图1例示了一个具有两个服务器10和数据存储装置11的典型现代计算中心。 Figure 1 illustrates a typical modern computing center two servers 10 and data storage means having 11. 服务器10包括一些子系统12,分别安装在一些工业标准的19英寸机箱内。 Server 10 includes a number of sub-12, were installed in a number of industry-standard 19-inch chassis. 存储装置11的子系统13安装在一个自定义规格的机架内。 11 of 13 subsystem storage device installed in the rack a custom specification. 服务器10和存储装置11通常处在一个环境受控的数据中心或服务器机房内。 Server 10 and the storage device 11 generally within an environmentally controlled data center or server room. 子系统12-13相互连接,而且还通过电缆或光缆与外部通信链路连接。 12-13 interconnected subsystems, but also to connect with the outside through a cable or fiber optic communication link. AC或DC功率也必须提供给子系统12-13,通常从一个电源通过楼面下的电缆15分配。 AC or DC power must be supplied to the subsystem 12-13, usually from a power source through a cable under the floor 15 of distribution.

图1这种基于机柜/机架的结构具有以下一些优点:(1)子系统可以任意布置在机房内,受到的只是冷却和电缆铺设的限制,以及(2)子系统可以具有不同的形状因子。 Figure 1 this arrangement cabinet / rack-based has the following advantages: (1) sub-system may be arbitrarily disposed in the engine room, the only restrictions being cooled and the cable laying, and (2) sub-system may have a different shape factors . 然而,这种封装结构在操作上有以下一些缺点:(1)升级困难;(2)电缆需要管理;(3)连接器不可靠;以及(4)布线和电缆组件不可靠。 However, this package there are shortcomings in the operation of some of the following: (1) difficult to upgrade; (2) cable management needs; (3) connector unreliable; and (4) wiring and cable assemblies unreliable. 这些问题会使今天的高性能的计算机和通信系统的总体不可靠,从而导致增大拥有、维护和升级这种系统的成本。 The overall performance of today's computer and communication systems of these issues will be unreliable, leading to increased ownership, maintenance and upgrade costs of such a system.

当前的计算机和通信系统的第一个缺点是在需要扩展系统的容量或功能时会遇到困难。 The first drawback of the current computer and communication systems to expand capacity is needed or when the function of the system will encounter difficulties. 即使系统设计成能适应一定程度的发展,也会出现这种情况。 Even if the system is designed to accommodate a certain degree of development, will happen. 例如,为了将一个新的服务器接入网络,需要将一些附加的通信电缆接到一个网络交换机上。 For example, a new server in order to access the network, needs to be some additional communication cable connected to a network switch. 然而,如果这个交换机的容量已完全分配,自由网络端口不足,升级就会相当困难和昂贵,特别是在进行扩展的同时系统必须仍然运行的情况下。 However, if the capacity of the switch has been completely assigned, insufficient free network port, the upgrade can be quite difficult and expensive, especially in the case of simultaneously performing the broadening system must still run.

当前计算机和通信系统的第二个缺点是对互连电缆铺设和布线的管理。 A second drawback of the current computer and communication systems is the management of interconnection cabling and wiring. 如果一个计算机设施内有大量的线和电缆,维修和支持员工错误地连接或断开电缆的事情并不罕见。 If there are a lot of wires and cables in a computer facility, maintenance and support staff mistakenly connect or disconnect the cable thing is not uncommon. 也可能出现其他的错误,诸如将电缆插入错误的子系统和留下电缆没有连接之类,特别是在必须迅速恢复系统运行时。 Other errors may also occur, such as the cable into subsystems and error type cable is not connected to the left, particularly in the rapid recovery system must be running. 对于光缆来说,还必须选择适当的速度、波长和距离参数。 For cable, it must also choose the right speed, wavelength and distance parameters.

当前计算机和通信系统的第三个缺点是连接器不可靠。 The current third disadvantage computer and communication systems are not reliable connector. 电连接器可能由于可能导致磨蚀的微摩擦磨损而随时间恶化。 Electrical connector may lead to erosion due to possible micro-friction and wear and deteriorate over time. 随着金属连接器的侵蚀,它的电阻增大,导致系统内出现间歇性故障或硬故障。 With the erosion of the metal connector, its resistance increases, resulting in intermittent failures in the system or hardware failure. 光连接器可以由于受到处置不当、震动或被手指油腻或灰尘污染而在系统内间歇性地开路。 Optical connectors can be due to improper disposal, vibration or dust contamination or greasy fingers and intermittently open circuit in the system. 此外,光电收发器也可能失灵。 In addition, optical transceivers may malfunction. 这些危险和故障导致系统的维护费用增大。 These risks and failures lead to system maintenance costs increase.

当前计算机系统的第四个缺点是电缆不可靠和成本高。 Current computer systems fourth disadvantage is that the cable is not reliable and high cost. 电缆和光缆都可能被断开、裂缝、弯曲、挤压或受到其他不当的处置。 And optical cables are likely to be broken, cracks, bending, squeezing or otherwise improper disposal. 基于玻璃的光缆还可能由于被踩或超过弯曲半径而损坏。 Also may be due to being stepped on or over bend radius and damage the glass-based fiber optic cable. 虽然电缆通常设计成能满足一定的系统参数,但它们并不总是制造成满足这样的容差。 Although the cables are typically designed to meet certain system parameters, but they are not always fabricated to meet this tolerance.

电缆也可能载有不合需要的在机架地或信号地处于不同电位的各子系统之间的屏蔽电流或地电流,特别是在这些子系统由不同的AC分支电路供电时。 Cable may also contain between subsystems in a rack or a signal to be at a different potential undesirable shield or ground current, especially when these subsystems from different AC branch circuit. 电缆也可能不希望地捡取外部电磁干扰或静电放电。 Cable also may not want to seizure external electromagnetic interference or electrostatic discharge. 这些不需要的屏蔽、地或信号电流可能在子系统之间的通信中引起间歇性错误或硬错误,导致在整个系统内出现暂时性的故障或硬故障。 These unwanted shield, or the signal current may cause intermittent errors or hard errors in communication between subsystems, resulting in a temporary failure or hard fault occurs within the entire system.

以上这些缺点都会增加现有计算机和通信系统的不可靠性、不灵活性和成本。 These drawbacks will increase the unreliability of existing computer and communication systems, inflexibility and cost. 因此,有必要开发一种互连可靠而简单的、扩展和维修容易的模块化计算机系统。 Therefore, it is necessary to develop a reliable and simple interconnection, expansion and maintenance easy modular computer system.

一个电容性耦合器包括一个半耦合器42和一个半耦合器43两个部分。 A capacitive coupler comprises two portions 43 a half coupler 42 and one half coupler. 虽然每个半耦合器既可以包括发送器和又可以包括接收器,但为了清晰起见图4中只示出了一个在半耦合器42上的发送器垫片44和一个在半耦合器43上的接收器垫片45。 Although each half-coupler may include both a transmitter and a receiver and can include, but for clarity in FIG. 4 shows only a half-coupler in the transmitter 42 on the spacer 44, and a half-coupler 43 receiver gasket 45. 发送半耦合器42处在子系统40的表面48上。 Send half coupler 42 at the upper surface 40 of the subsystem 48. 接收半耦合器43处在子系统41的表面49上。 Receiver half 43 at the upper surface of the coupler 41 of the subsystem 49. 半耦合器42将电信号传送给半耦合器43。 Half coupler 42 to electrical signals to the half-coupler 43. 这些信号是时变的,用来对在子系统40和41之间传送的信息编码。 These signals are time-varying, used to encode information between subsystems 40 and 41 are transmitted.

为了改善性能,子系统通常发送和接收差动形式的电信号,即正信号和负信号的互补对。 To improve performance, the differential transmission and reception subsystems typically form an electrical signal, i.e., the positive and negative signals of the complementary pair. 因此,需要两个垫片对在两个子系统上的相对半耦合器之间传送一个差动信号。 Therefore, the need for spacers between the two subsystems on two opposite half-coupler transmits a differential signal. 图5例示了一个支持差动传信的差动电容性耦合器。 Figure 5 illustrates a differential signaling support differential capacitive coupling. 这个差动电容性耦合器包括半耦合器52和53。 The differential capacitive coupler includes a coupler half 52 and 53. 半耦合器52包括差动垫片对54和55,分别与子系统引线50和51连接。 Half-coupler 52 includes a differential pair of shims 54 and 55, respectively connected to the leads 50 and 51 subsystem. 半耦合器53包括相对的差动垫片对56和57,分别与子系统引线58和59连接。 Half-coupler 53 includes opposing spacer 56 and the differential 57, respectively connected to the leads 58 and 59 subsystem. 垫片55和57传送差动信号的正信号。 Gasket 55 and 57 transmit a positive signal of the differential signal. 垫片54和56传送差动信号的负信号。 Negative signal pads 54 and 56 transmit differential signals.

图6示出了一个支持一个差动信号的差动垫片对(如图5中的差动垫片对54-55)的侧视图。 Figure 6 shows a support for a differential signal of the differential pair of shims (shown in Figure 5, the differential pair of shims 54-55) a side view. 它包括一个不导电的基片60,上面淀积或贴有金属垫片61和62。 It comprises a non-conductive substrate 60, or a metal is deposited on top of spacer 61 and 62. 金属垫片61和62被一个非常薄的绝缘介电材料层65覆盖,而分别通过导电引线63和64与子系统电路(未示出)连接。 Metal shims 61 and 62 are a very thin insulating layer of dielectric material 65 covered, respectively, by conductive leads 63 and 64 and subsystem circuit (not shown). 优选的是,引线63-64通过基片内的小通路66接到金属垫片61-62上。 Preferably, the lead 63-64 through a small passage 66 within the substrate connected to the metal pads 61-62.

在本发明的一个优选实施例中,半耦合器用标准的多层厚膜丝网印刷过程陶瓷模块技术设计制造。 In a preferred embodiment of the present invention, the semi-coupled Used standard multilayer thick film screen printing process, a ceramic module design and manufacturing technology. 图6中的基片60用氧化铝制成,厚度为1毫米。 Figure 6 formed from alumina substrate 60, a thickness of 1 mm. 金属垫片61-62优选的是用7微米厚的银钯合金构成。 Metal gasket 7 is preferably 61-62 m thick silver-palladium alloy. 电介质涂层65优选的是用相对电容率或介电常数为8至10的7微米厚的标准可结晶丝网印刷厚膜介电材料制成。 A preferred dielectric coating 65 with a relative permittivity or dielectric constant of 7 microns thick 8-10 crystallizable standard screen printed thick film dielectric material. 一种优选的介电材料是DuPontElectrics QM44。 A preferred dielectric material is DuPontElectrics QM44. 垫片上的电介质涂层可以提供每个垫片大约500V的静电放电(ESD)隔离(或者在差动对垫片之间1000V的ESD隔离)和1兆欧的电阻。 Dielectric coating may be provided on each of the spacer shims of approximately 500V electrostatic discharge (ESD) isolation (or 1000V isolation between differential gasket ESD) and a one megohm resistor. 假设子系统电子设备提供了附加的ESD输入串联保护。 Assuming electronics subsystem provides additional input series ESD protection.

在两个电容性半耦合器适当对准以形成一个电容性耦合器时,电介质涂层65优选的是与相对的半耦合器的电介质涂层轻微物理接触。 In both capacitive coupling half is properly aligned to form a capacitive coupling, the dielectric coating 65 is preferably in contact with the opposite half of the coupler dielectric coating slight physical. 紧邻的差动金属垫片和电介质涂层以及任何不希望的插入空气隙形成了一个平行板电容器。 Metal gaskets and immediately adjacent differential dielectric coating and any undesirable air gaps inserted to form a parallel plate capacitor. 由于电容器的位移电流,时变信号在两个相对的半耦合器之间以电磁方式传送。 Since the capacitor of the displacement current, time-varying signal transmitted electromagnetically between two opposing half-coupler.

图7示出了图6的差动电容性半耦合器的顶视图。 Figure 7 shows a top view of FIG differential capacitive coupling half 6. 金属垫片71和72配置在基片70上,被一层介电材料(未示出)覆盖。 Metal shims 71 and 72 disposed on the substrate 70, is a layer of dielectric material (not shown) covers. 电引线74和75分别将垫片71和72连接到子系统的电子设备上。 Electrical leads 74 and 75 to liner 71 and 72 are respectively connected to the electronic equipment subsystems. 垫片71-72的外尺寸通常是每个边为5至9毫米。 Gasket outer dimensions are typically 71-72 each edge of 5-9 mm. 正垫片71和负垫片72之间的间距通常在2至6毫米范围内。 72 is the spacing between the spacer shims 71 and the negative is usually within the range of 2-6 mm.

图8并列例示了两个子系统A和B之间的多个差动电容性耦合器的优选实施例。 Figure 8 illustrates a plurality of parallel differential capacitive coupling between the two subsystems A and B of the preferred embodiment. 子系统A和B通常分别包括内部电子电路86和84,提供如前面所说明的计算和通信功能。 Subsystem A and B, respectively, generally comprises an internal electronic circuit 86 and 84, there is provided computing and communication functions previously explained. 子系统A的差动垫片对处在半耦合器80上。 A differential gasket on the subsystem in a half coupler 80. 子系统B的差动垫片对处在半耦合器81上。 Differential shim subsystem B in the upper half of the coupler 81. 子系统A的发送半耦合器通过发送电路88接到子系统电子设备86上。 A half-coupler subsystem transmits through the transmitting circuit 88 connected to the electronic device 86 on the subsystem. 子系统A的接收差动垫片对通过接收电路87接到子系统电子设备86上。 A reception differential shims subsystem through a receiving circuit 87 for receiving an electronic device 86 on the subsystem. 类似,子系统B的发送和接收差动垫片对分别通过发送电路85和接收电路89接到它的电子设备84上。 Similarly, the differential transmission and reception of each shim subsystem B through the transmission circuit 85 and reception circuit 89 connected to the electronic device 84 on it. 注意,子系统A的接收垫片对82子系统B的发送垫片对83相对。 Note that the receiving subsystem A spacer shim 82 of the transmission subsystem 83 relative to B.

由于有四个差动垫片对连接到子系统A的发送器88上和有四个差动垫片对连接到子系统B的接收器89上,因此有四个信道可以用来同时将数据从子系统A传送给子系统B。 Since there are four differential pair of shims A subsystem connected to the transmitter 88 and the gasket has four differential pair is connected to the receiver subsystem B on 89, so there are four channels of data can be used simultaneously A transfer from subsystem to subsystem B. 在相反方向上,四个信道可以用剩下的那些差动垫片对将数据从子系统B传送给子系统A。 In the opposite direction, the four channels can be used for the rest of those differential shim B transmits the data from the subsystem to the subsystem A.

每个子系统的发送和接收耦合器的数目取决于子系统电子设备需要的所需子系统互连通信带宽。 The number of transmit and receive coupler for each subsystem depends on the electronic device subsystems interconnected subsystems required communication bandwidth required. 例如,如果每个垫片或线对具有3.125吉比特/秒的能力,那么每个耦合器的四个单向差动线路的总带宽就为12.5吉比特/秒。 For example, if each line of the spacer or ability 3.125 Gbit / s, then the total bandwidth of each of the coupler of the four-way differential line on the 12.5 Gbit / s. 就双向来说,也就是12.5吉比特/秒进入子系统和12.5吉比特/秒送出子系统。 On two-way, it is 12.5 Gbit / s into the subsystem and 12.5 Gbit / s sent subsystem. 如果每个差动线路是8B/10B编码的,一对具有这四个双向信道的子系统之间的总可用带宽为20吉比特/秒,或2.5吉字节/秒。 If each differential line is 8B / 10B encoding, the total available bandwidth between the pair of subsystems having four bi-directional channel is 20 Gbit / s, or 2.5 gigabytes / sec.

半耦合器80可以按照基于分组的通信数据链路物理层标准(如Ethernet、Fibre Channel或InfiniBand)将一个或多个独立的比特串行数据信道传送给图8的半耦合器81。 Half-coupler 80 may be transferred to the half-coupler 81 of FIG. 8 in accordance with the communication data link physical layer standards (such as Ethernet, Fibre Channel, or InfiniBand) packets based on one or more separate bit serial data channel.

在本发明的优选实施例中,假设物理层是基于比特串行的8B/10B数据编码、不归零和差动电压电平的。 In a preferred embodiment of the present invention, it is assumed the physical layer is based on bit serial 8B / 10B encoded data, not zero, and the differential voltage level. 8B/10B编码例如可参见美国专利4,486,739“Byte-oriented DC-balanced(0,4)8B/10B PartitionedBlock Transsmission Code”。 8B / 10B encoding, for example see U.S. Patent No. 4,486,739 "Byte-oriented DC-balanced (0,4) 8B / 10B PartitionedBlock Transsmission Code". 接收时钟可以由子系统电子设备从所接收的串行数据流得出。 Subsystems receive clock can be derived by the electronic device from the received serial data stream. 也可以采用其他数据链路和物理层协议,虽然一般说来电容性耦合器需要足够的带宽来传送数据链路码的最低频率分量。 Also possible to employ other data link and physical layer protocols, although the capacitive coupling generally requires enough bandwidth to transmit the data link code lowest frequency component.

图9例示地示出一个典型的立方形子系统模块的优选实施例的主要功能的方框图。 The main function of a block diagram of a preferred embodiment illustrated in FIG. 9 shows a typical embodiment of cubic subsystem module. 这个子系统包括一个8端口、低等待时间的基于分组的交换机芯片90,它与六个半耦合器91-96连接和通过网络接口芯片(NIC)98与内部处理器97连接。 This subsystem consists of an 8-port, low-latency packet-based switch chip 90, which is connected and 91-96 (NIC) 98 is connected to the internal processor 97 via the network interface chip with six half-coupler. 此外,交换机90还通过媒体访问控制器(MAC)91和编码器/解码器(ENDEC)和串行器/解串行器(SERDES)芯片92接到一个外部网上。 In addition, the switch 90 through the media access controller (MAC) 91 and the encoder / decoder (ENDEC) and serializer / deserializer (SERDES) chip 92 receives an external network. 这个连接通常位于在一个系统内的一个外部子系统的外表面,以便于接入。 This connection is usually located in the outer surface of a system according to an external subsystem, to facilitate access. 以上面所举耦合器的参数为例,这个立方形子系统将提供为20吉字节/秒(82.5)的进出子系统的总带宽。 Cited above, coupled with the parameters, for example, this subsystem will provide 20 cubic gigabytes / sec (8 2.5) out of the total bandwidth of the subsystem.

在本发明的优选实施例中,低损耗差动耦合器的特性阻抗应该从子系统电子设备经过线对传输线直到差动半耦合器接近于某个固定值,如100欧姆。 In a preferred embodiment of the present invention, the characteristic impedance should be low-loss from the differential coupler subsystem electronic device via wire until the differential pair of transmission lines is close to a half-coupling fixed value, such as 100 ohms. 传输线可以是两根分开的50欧姆同轴电缆;100欧姆差动对同轴电缆;100欧姆双绞线;或者双轴同轴电缆。 Transmission lines may be two separate 50-ohm coaxial cable; 100 ohm differential pair coaxial cable; 100 Ohm twisted pair; biaxial or coaxial cable. 差动传信线对是优选的,因为它在两根线上传送电磁信号,以电磁波传播的方式通过耦合器,而不传送任何显著的返地电流或其他可能引起不希望的噪声干扰的共模电流。 Differential signaling pairs are preferred because it transmits electromagnetic signals in the two lines, by way of an electromagnetic wave propagating through the coupler, but not to transfer any significant return ground current or other noise may cause undesirable interference co mode currents. 优选的差动信号电压电平通常是峰-峰值在1V以下。 Preferred differential signal voltage level is usually peak - at below 1V.

此外,电容性耦合器设计成使得它的频率响应在预期的工作范围中可合理达到的前提下尽可能不衰减,通常频率通带从100兆赫到7吉赫。 Furthermore, the capacitive coupling is designed such that its frequency response at the desired operating range as reasonably achievable premise does not decay, usually the frequency passband from 100 MHz to 7 GHz. 高频滚降要求由接收电子设备的能力确定,以从信号恢复编码数据,在接收电子设备给出接收“眼图”。 High frequency roll-off is determined by the capacity requirements of the receiving electronic device, to recover the signal from the encoded data, received by the receiving electronic apparatus is given in the "eye diagram." 这些信号处理电路可以包括在发送之前或在接收之后对编码信号执行反变换的能力,以便除去与频率有关的码间干扰。 These signal processing circuits may be included in or before sending a coded signal to the ability to perform an inverse transform in order to remove inter-code interference frequency dependent after reception. 低频滚降要求由需要通过耦合器发送的最低频率给出,如由物理层代码和信道比特错误可靠性所规定的。 Low-frequency roll-off request from the lowest frequency to be transmitted through the coupler is given, such as the physical layer channel bit error code and the reliability requirements. 随着所传送的数据速度和频率内容的增加,对最小电容的要求降低。 With increased speed and frequency content of the transmitted data, the requirements for minimum capacitance decreases. 例如,8B/10B码将代码规定成在链路上不能有连续五个以上的比特具有同样极性。 For example, 8B / 10B code is a predetermined code into the link can not have more than five consecutive bits having the same polarity. 例如,一个3.125吉比特/秒信号(具有320ps比特信元宽度)没有显著的在1/((5+5)0.32ns)=312兆赫以下的低频内容。 For example, a 3.125 Gbit / s signal (having a bit cell width 320ps) no significant at 1 / ((5 + 5) 0.32ns) = 312 MHz or less low frequency content.

在本发明的优选实施例中,在构建期间和垫片淀积之前,用标准硅片研磨机将半耦合器氧化铝基片研磨到正负3微米的平坦容差或者在必要的垫片区域有更好的平坦容差。 In a preferred embodiment of the present invention, prior to and during the build spacer deposition, using a standard silicon wafer grinder half coupler alumina substrate polished flat to plus or minus 3 micrometers or tolerances necessary spacer region have a better flatness tolerance. 这样做可以大大减小在相对的电容性半耦合器之间形成不希望有的空气隙。 This can be greatly reduced between the opposed capacitive coupling half formed undesirable air gaps. 由于耦合器可以模型化成两个电容器串联,第一个是由于任何空气电介质形成的Cair,第二个是由于垫片上的电介质涂层形成的Ccoating,因此电容性耦合器的总近似电容可通过1/(1/Cair+2/Ccoating),接近于Cair,即使Ccoating无限增大也不能超过Cair。 Since the coupler can be modeled as two capacitors in series, the first one is for any Cair air dielectric formed, the second is due to the dielectric coating Ccoating spacer formed on, and therefore the total capacitive coupling of the capacitor can be approximated by 1 / (1 / Cair + 2 / Ccoating), close to Cair, even Ccoating unlimited increase can not exceed Cair. 然而,优选采用高的介电膜电容率,因此是高的Ccoating,因为这会导致更接近由空气隙决定的电容Cair的总电容。 However, it is preferable to use a high permittivity dielectric film, and therefore is high Ccoating, because this leads to closer to the total capacitance of the air gap determines the capacitance Cair. 典型的在接触的半耦合器之间形成的电容,取决于半耦合器的大小和陶瓷衬底的平坦度,在20至100皮法之间。 Typical capacitance between the contact half-coupler formed, depending on the flatness of the size of half couplers and ceramic substrate, between 20 and 100 picofarads.

除了氧化铝之外,耦合器基片的另一种优选材料是柔性的聚酰亚胺膜而不是刚性的陶瓷板。 In addition to alumina, another preferred coupler of the substrate material is a flexible polyimide film instead of a rigid ceramic plate. 聚酰亚胺膜基片的优点是它不需要是精确平坦的,而只需要与它的相对的柔性聚酰亚胺半耦合器一致。 Advantages of the polyimide film substrate is that it does not need to be precisely planar, but only need to be consistent with its opposite flexible polyimide half-coupler.

至于金属垫片上的电介质涂层,除了Dupont QM44之外,也可以使用其他高介电的材料,如基于钛氧化物的钛酸钡,它的介电常数为30至60。 As for the dielectric coating on the metal gasket, in addition Dupont QM44 addition, also possible to use other high dielectric material, such as titanium oxide, barium titanate-based, it has a dielectric constant of 30 to 60.

概括地说,电容性半耦合器安装在子系统的外表面上,使得它们刚好以轻微压力与相对的半耦合器接触,以便尽量减少任何插入的空气。 Broadly speaking, the capacitive coupling half mounted on the outer surface of the subsystems, such that they are just a slight pressure contact with the opposite coupling half, in order to minimize any intervening air. 在耦合器的承载件的表面上可以提供一些对准凸起和凹陷,使得发送垫片恰好与相对的接收垫片对准。 On the surface of the carrier member of the coupler can provide some alignment projections and recesses, so that the transmission spacer is exactly aligned with the relative received gasket. 图10示出了带有一个对准机构和在半耦合器之间提供轻微压力的承载件的电容性耦合器的一个优选实施例。 Figure 10 illustrates a capacitive coupling of a carrier having a preferred alignment mechanism between the half and the coupler provides a slight pressure embodiment. 垫片103安装在氧化铝基片1001上,而氧化铝基片1001安装在塑料承载件101上。 Spacer 103 is mounted on an alumina substrate 1001, and an alumina substrate 1001 is mounted on a plastic carrier member 101. 塑料承载件101再安装在一个子系统表面的开口(未示出)内。 Plastic carrier 101 to install in the open surface of one subsystem (not shown). 有一个弹簧机构104缓和地将与基片100相连的承载件101从子系统的中央向外推。 There is a spring mechanism 104 will be gently pushed outwardly from the central subsystem 101 and the substrate 100 is connected to the carrier member. 在两个子系统相互滑过时,用塑料承载件101将两个半耦合器的基片相互分开,相互移过。 Slide over each other when the two subsystems, the plastic carrier 101 with two half couplers substrate separated from each other, moved past each other. 塑料承载件101具有凸起106,在移动时凸起106将相对的塑料承载件102推离,而在适当位置时凸起106进入相对的承载件102上的凹陷(类似承载件101上所示的凹陷108)内。 Plastic carrier 101 having a projection 106, the projection 106 relative to push away the plastic carrier 102 while moving, in position while the projection 106 enters the recess opposite bearing member 102 (similar to the carrier member 101 shown on the depression 108) inside. 半耦合器承载件上的凹陷108可以具有圆锥形状,以引导与它们相对的凸起更为准确地进入适当位置。 Depression half coupler bearing member 108 may have a conical shape, with their relative to the guide projection more accurately to the appropriate position. 塑料承载件101-102需要一些侧向运动的自由度,以适应子系统的对准误差。 101-102 plastic carrier need some degree of freedom of lateral movement, to accommodate alignment errors subsystem.

重要的是应与相对的耦合器垫片对准,因为任何对准误差将减小耦合器的有效电容,从而降低它的性能。 Is important to the alignment of the gasket opposite the coupler, as any misalignment will reduce the effective capacitive coupling, thereby reducing its performance. 差动耦合器垫片在差动半耦合器的正、负垫片的方向上的对准误差不应该超过正、负垫片之间间距的若干分之一,否则会有不希望有的正与负垫片耦接的情况发生。 Differential coupling gasket on the positive and negative direction of the differential gasket half coupler alignment error should not exceed the positive and negative space between one of several sub-gasket, or there are undesirable the case of negative spacer coupled occur. 在与差动半耦合器的这两个垫片垂直的方向上的对准误差不应该超过离任何周围垫片或基片边缘的距离的若干分之一,或者大到使耦合器的电容有明显降低并损害信号质量。 In the direction of the differential of these two half-coupler gasket perpendicular alignment error should not exceed the distance from any one of several points around the edge of the substrate or a gasket, or as large as the capacitance of the coupling device has significantly reduced and damage signal quality.

虽然以上是结合本发明的优选实施例对本发明进行具体说明的,但熟悉该技术领域的人员可以理解,在不背离本发明的精神实质和专利保护范围的情况下其中无论在形式上还是在细节上都可以作出种种改变。 While the above is a combination of preferred embodiments of the present invention, the present invention will be specifically described, but the person familiar with the art will be appreciated that, without departing from the spirit and scope of the present invention patent case wherein both in form and in detail Xanadu various changes may be made. 因此,应认为所说明的只是例示性的,而本发明的专利保护范围仅由所附权利要求书规定。 Therefore, to be considered the illustrated exemplary only, and the scope of the patent protection of the invention is only defined by the appended claims book.
