I 10 Claims.
-1 This invention relates to improvements in couplings or connectors, particularly --electrical connectors of the quick detachable, irictionagrip plug-and-socket type. The objects of the inventionare to devise a'strong, simple, economical and efficient electrically conductiveconnectorof the above type that will provide increased friction between the plug 'and: socket members at theirsurface of contact and thus-prevent separation or-loss of surface contact of said members under service conditions and that will Provide for cleaning the contact surface of the socket member by theplug member during the engagement and disengagement thereof. The invention consists in a hollow cy-l-indrioal plug member with oblique circumferentially-spaced slits therein and a member having a cylindrical socket of smaller diameter than the slitportion of said plug member, whereby endwise insertion of said plug member in saidsocket member will compress the slit portion and cause it to bear resiliently against the wall of saidsocket. The
invention also consists :inproviding the slit hollow cylindrical plug member with a central reinforcing pinor core and in providing an-annular space between said plug and core adaptedto permit the slitportion to spring radially inwardlywhen said plug is forced into-said socket. Thei-nvention also consists in the electrical connector and in the parts and combinations and arrangements of parts hereinafter described and claimed.
'.In the accompanying drawing, which for-ms part of this specification and wherein likesymbols refer to like parts wherever they occur,
Fig. 1 is a side elevational View of an electrical connector embodying my invention,
'Fig. 2 is an end elevational view thereof,
Fig. 3 is a cross-sectional view on the line 3-4 in Fig. 1,
Fig. 4 isa side elevational View of the plug member of the connector,
"Fig. 5 is a central long-itudinalsectional view of the socket member of the connector,
Fig. 6 is an enlarged central.longitudinaksection on the line 6-6 in Fig. 4,
'Fig. 7 is a cross-sectional view onthe line 1-1 in Fig. 6 and Fig. 8 is an enlarged fragmentary central longitudinal sectional view on the line 88.in,Fig.I .1.
In the accompanying drawing, our invention is shown embodied in-an electrical connector of the friction grip, axially engageable -and disenhaving.-a cylindrical ax ial; :socket .2 opening through one end thereof and-an electrically.conductive inemberfl having a reduced hollowscylindrical plug tat-one end thereof :adapted for endwise insertion in and removal fromusaidfcylindiiical socket. Located withinand extending: from end to end of 'thetubular plug portion d'of'the member 3 is a centralcore or pin 5'thatx'ispressfitted in or otherwise rigidly secured to; said :memher at the inner end zof said hollow plug portion. The pin 5 is of smaller diameterthan thejinside diameter of the hollow plug-4 so as to provide an annular clearance -space'-6 between saidlz zpin and plug.
.In the engagedposition of the plug andsocket members"! and -3., the annular :shoulder 1 formed by the reduced-tubular plug portion 4 0f the member "3 abutsagainst the adjacent plug receiving end of the member I. At'their remote ends, each of the plug and Socket members l and 3 has intersecting axial and diametr-al holes (18 therein adapted to receive the wires zorwcabl'es not shown) that are to be electrically connected by said members.
The tubular or' hollow cylindricalplug portion 4 of the member 3 has end portions 9 of "slightly portion and terminate in -thesmallertdiameter end portions 9 thereof. These 'circumferential ly spaced oblique or helicalslits I I dividethe large diameter intermediateporti'on ill of the hollow plug 4'into a series of relativelythick-circumferentially spaced obliquely or, helicall'y 'dispose'dlradially. resilient sections 42. i'Ihus, when the hollow cylindricali-plug portion i 10f .the phIg member -3 is forced into: the cylindricalfsocket' -t of the socket member I, the circumterenti-ally spaced obliquely or helically.disposedssections I2 ofthe larger diameter intermediate portioni fl of said plug portion are forced radially "inwardly and thus bear resiliently against' the wall-of said cylindrical socket with av pressurev suflicient to frictionally resist endwise 'separationzlo'f sa-id members. The-annular clearance space fi 'ba tween the tubular plug portion-' 4 of theplug member-3' and the centralupin or core S- therein permits the slit large diameter intermediate portion Hl of said tubu lartplug portion to spring radially, inwardly; 1 and s-ai'd 1 pin also-1prewer'its 3 said tubular plug portion from being crushed or bent. The desired amount of friction between the plug and socket may be obtained by varying the diameter of the intermediate portion in, the length and width of the helical or oblique sections l2 thereof and the width of the annular clearance space 6 between the reinforcing or supporting pin and the hollow plug 4. The small diameter portion 9 at the entering end of the plug 4 serves as a pilot for guiding said plug into the socket 2; and the oblique or helical slits Ii provide cutting edges that function after the manner of a reamer to keep the wall of the cylindrical socket 2 bright and clean and electr diameter cylindrical socket to bear resiliently throughoutits entire length against the wall thereof and thus frictionally resist endwise separation of said members.
