At least one or a plurality of opening 110a-c can limit through the periphery of sealing until all opening 110a-c, and the periphery of said sealing comprises at least a portion of a pair of second beam 114 and a pair of first beam 108.Second beam 114 can limit for example along vertical L opposite external margin 116 at interval; Thereby limit second size or width W 2, the second sizes or width W 2 and be defined at least one second beam 114 between the external margin 116 of all second beams 114 along vertical L.Shading body 102 limits second distance D2, and second distance D2 quilt is along between the adjacent external margin 116 that vertically is limited to the second adjacent beam 114.Should be appreciated that second distance D2 can correspondingly reduce when second width W 2 increases, and second distance D2 can correspondingly increase when second width W 2 reduces.Should be appreciated that second distance D2 limits each opening 110a-c along corresponding size longitudinally, and one of them the second distance D2 of opening 110a-c can be different from one or more until all opening 110a-c.
Should be appreciated that first beam 108 that second beam 114 makes first electric connector 22 electric connection each other; Between following, to set up the common ground path: 1) two or more ground connection abutting ends 106 are until all ground connection abutting ends 106; 2) two or more ground connection installation ends 104 are until all ground connection installation ends 104 and 3) at least one ground connection abutting end 106 until all ground connection abutting ends 106 and at least one ground connection installation end 104 until all ground connection installation ends 104.When first and second electric connectors 22 and 24 match, and corresponding ground connection abutting end 106 and 66 (with reference to figure 4A) is when matching, and common ground shields 100 foundation and strides across the mating interface 30 of electric connector 22 and 24 and the common ground path of 34 extensions.Therefore, the common electrical grounding path that strides across first electric connector 22 is set up in common ground shielding 100 before first and second electric connectors 22 and 24 match.After first and second electric connectors 22 and 24 matched, common ground shielding 100 was also set up and is striden across mating interface 34, strides across the electrical ground path of at least two ground connection abutting ends 66 of second electric connector 24 until all ground connection abutting ends 66 particularly.Therefore; First and second electric connectors 22 and 24 can limit corresponding first and second grounding paths; When first and second electric connectors 22 and 24 matched, said first and second grounding paths limited first and second electric connectors 22 and 24 public grounding paths.
Should be appreciated that shading body 102 limits a plurality of holes 110, hole 110 can be extended between the first adjacent beam 108, and can between the second adjacent beam 114, extend.Though the plane endoporus 110 being limited vertical L and horizontal T is the general rectangular shape, should be appreciated that hole 110 can limit Any shape as required, for example, according to the geometry of the external margin 116 of the external margin 112 of first beam 108 and second beam 114.Though shading body 102 each first adjacent beam 108 between limit four second beams 114 and three respective openings 110a-c; But should be appreciated that shading body 102 can comprise a plurality of second beams 114 as required, to limit a plurality of respective aperture 110 as required.In addition, each opening 110a-c limits the long-pending respective area that equals first distance B 1 and second distance D2.Therefore; The area that should be appreciated that each opening 110a-c can change; For example, through changing first and second width W 1 and the W2 of first beam 108 and second beam 114 respectively, and the number through changing second beam 114 with between the second adjacent beam 114 of corresponding change along the distance of vertical L.Should also be clear that the accumulation area in hole 110, and the therefore accumulation area of opening 110a-c, limit total open area OA of shading body 102.Total open area OA of shading body 102 can increase and reduce, for example through the number of change opening 110a-c and further through change the size of opening 110a-c with aforesaid mode.Thereby, can provide to have different open area, and the external member of the common ground of one or more different area until all opening 110a-c shielding 100.
Recognized when first and second electric connectors 22 and 24 match; First and second electric connectors 22 and 24 limit mating area 118 along side direction A, and for example mating area 118 can be restricted at least one or both and the ground connection abutting end 66 of the signal electrical contact 44 of second electric connector 24 and at least one or two (with reference to figure 4A) overlapping areas of abutting end 50 of abutting end 38 and ground connection abutting end 106.Should also be clear that the impedance at mating area 118 places also increases when total open area OA of shading body 102 increases.For example; If not perforation of shading body 102; And therefore total open area is zero, and the impedance at mating area 118 places is lower than the expection impedance of electric coupler component 20 substantially, so that the impedance at mating area 118 places does not match about the expection impedance of electric coupler component 20.
In addition, common ground shielding 100 can be configured to when first and second electric connectors 22 and 24 match one or more at least until all opening 110a-c one in the signal contact 44 of overlapped signal contact 35 and second electric connector 24 or both at least in part.According to illustrated embodiment, the first opening 110a of common ground shielding 100 is at least a portion of overlapped signal contact 35 and signal contact 44 fully, for example, and at abutting end 50 places, at mating area 118.The 3rd opening 110c of common ground shielding 100 can; As shown in the figure at mating area 118; Overlap at least a portion of signal contact 44 of second electric connector 24, or can be at least a portion of the signal contact 44 of mating area 118 complete overlapping second electric connectors 24.The area of each opening 110a-c can be reduced to reduce crosstalking of mating area 118 places.For example, according to an embodiment, when first and second electric connectors 22 and 24 matched, the area of each opening 110a-c can be less than the wavelength of signal of signal contact 35 that is striden across first and second electric connectors 22 and 24 and 44 transmission.The area of opening 110a-c can be reduced when the frequency of the signal that strides across signal electrical contact 35 and 44 transmission increases.
Therefore the number that should understand individual opening 110a-c and area and the open area OA expection impedance that is adjustable to make the impedance at mating area 118 places to mate electric coupler component 20 substantially always; And crosstalk and be lowered; Allow common ground shielding 100 to set up the common ground path of the corresponding earthing component at the mating interface 30 that strides across first and second electric connectors 22 and 24 and 34 places simultaneously, for example at mating area 118 places with aforesaid mode.In other words, hole 110 can limit balance through the impedance of mating area 118 and the area of crosstalking, and wherein crosstalks to raise relatively with signal frequency (or wavelength).
In addition, the common ground of first electric connector 22 shielding 100 can with the corresponding ground plate 62 of second electric connector (with reference to figure 4B) at interval, for example; With signal contact 44 zone that transversely T aims at of second electric connector 24 in; To limit a plurality of slits 120, slit 120 limits first distance along vertical L, and first distance can be fully approaching; Or equal second distance D2 substantially.Slit 120 can be further between adjacent ground connection abutting end 66 transversely T limit second distance, second distance can equal first distance B 1 of between the first adjacent beam 108 of common ground shielding 100, extending substantially.For example, should be appreciated that first beam 108 can be aimed at along vertical L with ground connection abutting end 66 when first and second electric connectors 22 and 24 match.Therefore, slit 120 can limit corresponding area, and its impedance matching that is sized to keep substantially striding across mating area 118 also reduces crosstalking of mating interface 34 places simultaneously.For example, the area in each slit 120 can be less than the wavelength of the signal of the signal contact that strides across second electric connector 24 44 transmission.
As stated, shading body 102 by about signal electrical contact 35 at side direction A upper offset, so that shading body 102 and signal electrical contact 35 are along lateral spacing distance B 3 (with reference to figure 2E) for example.In addition, ground connection installation end 104 can with the installation end 40 of signal contact 35 transversely T aim at.Therefore, when becoming one with shading body 102 when ground connection mounting portion 104, common ground shielding 100 can be included in the transitional region 122 of extending between shading body 102 and each the ground connection mounting portion 104.Transitional region 122 can stretch out towards corresponding common column CL along vertical L backward and along side direction A.Ground connection mounting portion 104 can transversely extend back along vertical L from transitional region 122 position of T aligned in general at the installation end 40 with signal contact.
As stated, common ground shielding 100 also can comprise at least one rib 124, for example a plurality of ribs 124, rib 124 support shading body 102 and from shading body 102 along the outside projection of side direction A to limit abutting end, for example the ground connection abutting end 106.According to illustrated embodiment, at least one until all ribs 124 from corresponding one first beam, 108 outside projections.According to illustrated embodiment, each rib 124 is molded and makes its protrusion to corresponding one first beam 108, and therefore becomes one with said corresponding one first beam 108.Therefore, rib 124 also can be called as protuberance, can construct as required alternatively though should be appreciated that rib 124.Rib 124 can be substantially constructed like the rib 74 of following ground plate 62 about second electric connector 24 saidly; And can be from first beam 108 along side direction A outside projection one distance; When first and second electric connectors 22 and 24 match; Be enough to the earthing component 59 with second electric connector 24, and particularly with ground connection abutting end 66, contact.Therefore, the ground connection abutting end 106 of first electric connector 22 can limit through the rib 124 from the 108 outside projections of first beam.At least a portion of rib 124 can be for example body 39 places and signal contact 35 transversely T aim at.For example, at least a portion of rib 124 can be placed in the adjacent differential signal that limited signal contact 35 between 45, and therefore replaceable discrete grounding contact.Thereby, first electric connector 22 can comprise replacement the adjacent differential signal of traditional electrical connector between the common ground shielding 100 of the discrete grounding contact that extends.
The selected performance characteristic that should be appreciated that common ground shielding 100 can be adjusted as required.For example; The area that opening 110a-c limits can be adjusted as stated; Total open area OA that shading body 102 limits can adjust as stated, and shading body 102 can further be adjusted with respect to the position of the signal contact 44 of second electric connector 24 when first and second electric connectors 22 and 24 match.For example; Shading body 102 can be arranged at vertical back of ground connection installation end 104; Or compare more near ground connection installation end 104 with the described embodiment of Fig. 2 A-E; This can 1) when first and second electric connectors 22 and 24 match; The part of the total open area OA that for example reduces at abutting end 50 place's overlapped signal electrical contacts 44, and 2) when first and second electric connectors 22 and 24 match, increases the slit 120 that is arranged between common ground shielding 100 and the ground plate 62 size along vertical L.In addition; Shading body 102 can be arranged at vertical front of ground connection installation end 104; Or compare further from ground connection installation end 104 with the described embodiment of Fig. 2 A-E, this can 1) when first and second electric connectors 22 and 24 match, the part of the total open area OA that for example increases at abutting end 50 place's overlapped signal electrical contacts 44; And 2) when first and second electric connectors 22 and 24 match, reduce to be arranged at the longitudinal size in the slit 120 between common ground shielding 100 and the ground plate 62.
And with reference now to 3A-D, shading body 102 and signal electrical contact 35 quilts are along side direction A spacing distance D4.Distance B 4 can be provided with size as required, and according to illustrated embodiment greater than distance B 3 (with reference to figure 2E).For example, common ground shielding 100 can comprise a plurality of dactylozoites 126, and dactylozoite 126 extends towards corresponding common column CL along side direction A forward and from shading body 102 along vertical L from shading body 102.According to illustrated embodiment, dactylozoite 126 extends from first beam 108.Dactylozoite 126 can be as shown in the figure becomes one with shading body 102, maybe can separate so that dactylozoite 126 and shading body 102 electric connection each other when by connector shell 31 supports from shading body 102.Each dactylozoite 126 as shown in the figure can be bifurcated, or can limit single solid dactylozoite as required.Should be appreciated that ground connection abutting end 106 can limit through dactylozoite 126, so that dactylozoite 126 is configured to electrically contact with the earthing component 59 of second electric connector 24.Transitional region 122 between ground connection installation end 104 and the shading body 102 can extend to the degree of depth that equals transitional region 122 so that shading body 102 is in substantially parallel relationship to common column CL extension along side direction A.
When first and second electric connectors 22 and 24 matched, dactylozoite 126 can contact earthing component 59, and contacted the ground plate body 64 of second electric connector 24 particularly.Alternatively, dactylozoite 126 can be configured to contact when 24 match when first and second electric connectors 22 the ground connection installation end 68 of second electric connector 24.Should be appreciated that the common ground shielding can also comprise aforesaid rib 124 and dactylozoite 126.Rib 124 can extend laterally the degree of depth that equals dactylozoite 126 and transitional region 122 substantially to limit from shading body 202 along side direction A; Thereby when first and second electric connectors 22 contact the earthing component 59 of second electric connector 24 when 24 match, for example at corresponding installation end 66 places.
Therefore electric coupler component 20 can comprise the crosstalk shields that can cooperate through common ground shielding 100 and first and second of ground plate 62 qualifications respectively.First can cooperate twines crosstalk shields, and for example the common ground shielding 100, comprise the first contact dactylozoite, and for example dactylozoite 126, and second crosstalk shields can limit the second contact dactylozoite, for example the dactylozoite that limits of ground connection abutting end 66.When first and second electric connectors 22 and 24 mate with each other, the first contact dactylozoite, for example dactylozoite 126; But entity contact ground plate 62, and the second grounding contact dactylozoite, for example; Dactylozoite ground connection abutting end 66 limits shields 100 but entity contacts common ground.
Alternatively, the degree of depth of rib 124 can be electrically connected when first and second electric connectors 22 and 24 match, to have only dactylozoite 126 to set up with the earthing component 59 of second electric connector 24 less than the degree of depth of dactylozoite 126.Should be appreciated that ground connection abutting end 106 can limit any proper depth on side direction A as required, with corresponding adjustment shading body 102 about signal electrical contact 35, and therefore common column CL, the offset or dish D4 on side direction A.
Thereby; Should be appreciated that the external member of electric connector 22 is configurable has different performance characteristics; Crosstalking or when being used for reducing unlike signal frequency and wavelength for example about other the identical electric connector that comprises discrete grounding contact rather than common ground shielding 100 by adjustment by adjustment, and can further dispose the operating process that is used at electric connector 22 and under the different impedance level, operate.For example, each of a plurality of electric connectors 22 can comprise the opening 110a-c of different numbers, and opening 110a-c has different areas, different total open area OA, and shading body can be located with respect to signal contact 35 differently.For example, the lengthwise position of shading body 102 can be different, and about signal contact 35 biasings.In all these different configurations, should be appreciated that open area, the zone that for example limits the opening 110a-c that extends through shading body 102, the position can be different from the connector to the connector.This position can be along the direction of the common column CL that is in substantially parallel relationship to signal contact, and along the direction perpendicular to the common column CL of signal contact is different substantially.
First electric connector 22 can be called as plug or pin connector, and its electrical contact 33 is configured to admitted by the complementary electrical contact of second electric connector 24, and second electric connector 24 can be described as socket connector.Alternatively, the electrical contact 33 of first electric connector 22 can be arranged to the complementary electrical contact of admitting second electric connector 24, thereby first electric connector 22 can be described as socket connector and second electric connector 24 can be described as pin connector.In addition; Because being oriented to, mating interface 30 is in substantially parallel relationship to mounting interface 32; So first electric connector 22 can be described as vertical connector, though should be appreciated that first electric connector can be provided as any expection be configured to substrate 28 is electrically connected to second electric connector 24.For example, first electric connector 22 can be configured to rigging-angle connector, and mating interface 30 is oriented to substantially perpendicular to mounting interface 32 thus.

Each lead frame assembly 46 also comprises earthing component 59; Can be configured to ground plate 62 according to illustrated embodiment earthing component 59; Or can be configured to independent ground connection electrical contact alternatively; Said ground connection electrical contact carried by lead frame housing 48 and be arranged to adjacent with the signal electrical contact 44 of second electric connector 24, for example with the differential signal that limits signal electrical contact 44 to adjacent.According to illustrated embodiment, each ground plate 62 is through a corresponding carrying of lead frame housing 48.Ground plate 62 limits the opposite ground connection installation end 68 that is arranged to the ground connection abutting end 66 that cooperates with the complementary grounding contact of electric connector 22 and is configured to be connected to substrate 26.
Ground connection installation end 68 can stretch out greater than the distance of the installation end 52 of signal electrical contact 44 along vertical L, and is as shown in the figure, or the distance of the abutting end 50 that equals signal electrical contact 44 substantially of can stretching out as required.Ground plate 62 limits and is arranged at a plurality of slits 79 between the adjacent abutting end 66.Ground plate 62 is configured to differential signal at adjacent row CL in addition provides electric screen between to 45.Ground plate 62 can by any suitable electric conducting material for example metal form, and comprise body 64, a plurality of abutting ends 66 that extend forward from body 64 and from body 64 to a plurality of installation ends 68 that extend below.Ground connection abutting end 66 can be constructed with installation end 52 like top abutting end 50 about signal electrical contact 44 with installation end 68 saidly.The ground plate 62 of each lead frame assembly 46 can be attached to lead frame housing 48 discretely or pass through the lead frame housing 48 coating shapings of respective leadframe assembly 46.For example, ground plate 62 can comprise lock bolt 89 (with reference to figure 1), and lock bolt 89 is from 64 extensions of ground plate body and be arranged to bonding wire frame shell 48 so that ground plate 62 is fixed to lead frame housing 48.
Continue with reference to figure 4A-F, each ground connection abutting end 66 of ground plate 62 can be configured to from body 64 along side direction A and vertical outward extending dactylozoite of L.For example, ground connection abutting end 66 can comprise the corresponding neck 61 that vertically extends forward from body 64.Neck 61 can be crooked in side direction on the direction of the signal contact 44 of lead frame assembly 46, so that corresponding abutting end 50 rough alignment of ground connection abutting end 66 and signal contact 44.Thereby ground connection abutting end 66 is configured to cooperate with the ground connection abutting end 106 of complementary first electric connector 22.Each abutting end 66 of ground plate 62 also can comprise the dactylozoite of a pair of horizontal bifurcated, the dactylozoite of said a pair of horizontal bifurcated comprise extend forward respectively vertically first or go up dactylozoite 63a and second or dactylozoite 63b down.Dactylozoite 63a and 63b can be crooked and be configured to cooperate with the abutting end 38 of electrical contact 35. Dactylozoite 63a and 63b flexible with bending when cooperating with abutting end 38, thereby normal force is provided.Compare with the dactylozoite 43 of signal electrical contact 44, dactylozoite 63a and 63b can further vertically extend forward.Each abutting end 66 stretches out and limits each the opposite end of dactylozoite 63a and 63b from ground plate body 64.
Each installation end 52 of ground plate 62 can limit from body 64 laterally to the neck that extends below 67 and from neck 67 to the installing terminal that extends below 69.Neck 67 and/or installing terminal 69 can tilt or bending towards electrical contact 44.Installing terminal 69 can limit and be arranged to pinprick formula or any suitable optional shape that is electrically connected to substrate 26.For example, installing terminal 69 can be pressed in the via hole that extends in the substrate 26, with the electric mark electric connection that extends or extend through substrate 26 along substrate 26.
The body 64 of ground plate 62 limits first outer surfaces 72 and about the second opposite outer surface 70 of first outer surface, 72 side direction.Second outer surface 70 can flush with the outer surfaces 58 of lead frame housing 48, but the outer surfaces 58 of projection process lead frame housing 48, or can inwardly concave about the outer surfaces 58 of lead frame housing 48.Thereby the size of electric connector 24 can remain unchanged with respect to the electric connector that its IMLA is carrying discrete grounding contact, for example, at United States Patent(USP) No. 7,497, those that describe in 736, the disclosure of this patent is incorporated into way of reference by integral body.First outer surface 72 is facing to the signal electrical contact 44 of lead frame assembly 46.Ground plate 62 can comprise engagement member, for example is installed in the first lip 65a in the slit in the outer surface 58 that extends laterally to lead frame housing 48 and is installed in lead frame housing 48 tops to catch the second lip 65b of lead frame housing 48 and ground plate 62.
Ground plate 62 can conduct electricity.For example, ground plate can be the metal crosstalk shields of impression and therefore reflect the electromagnetic energy that signal contact 44 produces in the use.Should be appreciated that ground plate 62 can be arranged to the absorption electromagnetic energy alternatively.For example; Ground plate 62 can be processed by one or more electroconductive magnetic absorbing materials; For example (Randolph, commercial
