Description

SYSTEM FOR COMPLETING THE SHIELD OF AN ALT CABLE * VKT.?ptpAn Field of the Invention This invention generally relates to the technique of electrical connectors and particularly to a system for terminating the metallic shielding of a high speed cable, such as the metallic fabric of the cable. BACKGROUND OF THE INVENTION A typical high-speed cable includes a conductor or central core surrounded by a tube-type inner dielectric. A shield is arranged outside the internal dielectric to shield and / or ground the cable. The shield is typically a tubular metal weave. However, one or more longitudinal conductor wires have also been employed and are commonly referred to as "ground return wires". An insulating jacket surrounds the composite cable outside the shield. Different types of connectors are used to terminate high-speed cables. The connectors typically have contacts that terminate in the core conductor core of the cable. The connectors also have one form or another of a termination member, to terminate the metallic shielding of the high speed cable, usually for grounding purposes. A typical system in these connectors terminates the metal shielding to the termination member by welding. Other systems utilize folding procedures, to fold at least a portion of the termination member securely to the metal fabric for common bonding purposes. With ever-increasing miniaturization of electronic components in various industries, such as the computer and telecommunications industries, along with the accompanying miniaturization of electrical connectors, considerable problems have been encountered in terminating miniaturized high-speed cables, particularly for finishing metallic shielding of the cable. For example, the outside diameter of a small coaxial cable may be in the order of .2286 cm (.090"). The outer diameter of the inner dielectric surrounding the conductor / core may be in the order of .1295 cm (.051). ") and the diameter of the core conductor / core can be in the order of .03048 cm (.012"). Coaxial cables that have even smaller dimensional parameters have been employed.The problems to finish these very small coaxial cables often surround Around finishing the metallic shielding of the cable, for example, if welding methods are used, applying heat (necessary for welding) in direct proximity to the metallic shielding, can cause thermal damage to the underlying inner dielectric and in fact, substantially disintegrate or degrade in internal dielectric If conventional pleat-type terminations are used, typical fold forces will often crush or deform the interior dielectric It surrounds the conductor / core of the cable. The above problems are further complicated when the metallic shielding of the high speed cable is not terminated to a cylindrical termination member, but the shielding is terminated with a contact or flat termination member. For example, it is known to terminate the tubular metal shield or fabric of a coaxial cable in a flat ground circuit pad on a printed circuit board. This is most often achieved by simply gathering the tubular metal fabric of the coaxial cable into a twisted strand or "pig tail" which in turn is welded to the flat ground pad in the printed circuit. Another example for terminating the shield or metal fabric of a coaxial cable to a flat earth member is illustrated in US Patent No. A. No. 5,304,069, dated April 19, 1994 and granted to the assignee of the present invention. In that patent, the metallic fabrics of a plurality of coaxial cables are terminated in a ground plate of a high-speed signal transmission terminal module. The conductors / cores of the coaxial cables are terminated in signal terminals of the module. To finish high-speed wire tubular armor or fabric in flat ground contact pads as in a printed circuit, or on the planar earth plate as in US Pat. previously referred to, or any other flat or non-tubular termination member, various design considerations shall be taken into account as has been found with the present invention. It will be understood that there is a transition zone created where the conductor / core of the high-speed cable passes from a "controlled environment" wherein the conductor / core is completely enclosed by the tubular metal shield or fabric to an "environment not controlled "wherein the tissue extends away from the conductor / core to terminate the non-tubular termination member. It is convenient that this transition zone be kept in an area as small as possible and as short as possible (ie lengthwise of the cable). Preferably, the metallic fabric or armor will be terminated over an area (or at least two points) spaced approximately 180 ° relative to the conductor / core of the cable. Preferably, the flat termination member should overlap or at least extend to the point where the metal shield or fabric is separated from its tubular configuration surrounding the conductor / core of the cable. Still further, it is desirable that the metal shield or fabric of any given high speed cable be terminated on the same side of the flat termination member as the core / center conductor of the cable. The present invention is directed to solving the problems identified above and satisfying the most possible of the previously identified design parameters in an improved system for terminating the metal shielding of a high speed cable to a termination member such as a ground plate. An objective therefore of the invention is to provide a new and improved system or terminal for terminating metallic shielding of high-speed cables. In the exemplary embodiment of the invention, the system is adapted to terminate the shielding of a high speed cable having an outer cover and an inner metallic shield as a portion of the outer cover removed to expose a portion of the metal shield. The system includes a two-part conductor termination member, which includes a cable receiving part and a terminal part. The cable receiving part includes a receptacle for receiving the high speed cable in direct coupling with its exposed metallic shield. A solder connection is applied between the exposed metal shield and the part that receives the cable in the receptacle. The terminal part is adapted to ground the metal shield. Additional intercoupling arrangement means are provided between the cable receiving part and the terminal part, to mount the cable receiving part in the terminal part in conductivity therewith. As described herein, the terminal part comprises a ground plate. The cable receiving part includes a pair of receptacles on each opposite side of the ground plate for receiving a pair of high speed cables in a generally parallel side-by-side relationship on both opposite sides of the ground plate. The receptacles are substantially cylindrical. In the preferred embodiment, each part is punched and formed of a conductive sheet metal material. The terminal part comprises a generally planar ground plate having a pair of projecting positioning arms on each of its sides to locate the cable receiving part therebetween. the complementary intercoupling mounting means includes a pair of elastic jaws in the cable receiving part, for clamping the terminal part between the projecting positioning arms thereof. Other objects, features and advantages of the invention will be apparent from the following detailed description taken in connection with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS The characteristics of this invention that are considered novel, are set forth with particularity in the appended claims. The invention, together with its objectives and the advantages thereof can be better understood by reference to the following description, which is taken in conjunction with the accompanying drawings, in which like reference numbers identify similar elements in the figures and where: FIGURE 1 is a perspective view of an electrical connector of a type in which the invention is applied; FIGURE 2 is a fragmented vertical section that is generally taken on line 2-2 of Figure 1; FIGURE 3 is a plan view of the terminal part of the two-part termination member; FIGURE 4 is a perspective view of a die-cast metal preform from which the cable receiving part of the two-part termination member is formed; FIGURE 5 is a side elevational view of the cable receiving part; FIGURE 6 is an end elevation view of the cable receiving part; FIGURE 7 is a perspective view of the cable receiving part receiving a plurality of coaxial cables; FIGURE 8 is a perspective view of the receiving part of cable and cables mounted on the terminal part; and FIGURE 9 is a perspective view of the terminal module mountable in the connector of Figures 1 and 2. With reference to the drawings in greater detail and first to Figures 1 and 2, the invention is incorporated in a shielded electrical connector, generally designated 10, which is a hybrid electrical connector, to terminate both slower data transmission line drivers and high speed conductors or high frequency transmission lines. In particular, electrical connectors 10 include a dielectric housing 12 (Figure 2) that mounts a plurality of data transmission terminals 14 (Figure 1). A conductive shield, generally designated 16, substantially encloses the dielectric housing 12 and has a cover portion 18 projecting forward with respect to the coupling ends of the data transmission terminal 14. A two-piece rear cover (not shown) substantially in coupling with that illustrated in the US Patent No. 5,358,428, dated October 25, 1994, is projected rearwardly of the housing 12 and shield 16. A molded sleeve 20, includes an integral cable strain relief 22 which is in engagement with a composite electrical cable 24, which includes both data transmission lines and high-frequency or high-speed transmission lines. A pair of knurled head screws 26 projects through the molded sleeve and includes externally threaded front distal ends 26a, for clamping the connector to a complementary docking connector, panel or other structure. As best seen in Figure 2, a high-speed signal transmission terminal module, generally designated 30, is inserted into a passage 31 in the dielectric housing 12, from its rear. The terminal module includes a pair of identical terminal blocks 30a and 30b that hold a ground plate, generally designated 32 therebetween. Each terminal block includes a post 34 and a recess. The post from each terminal block extends from each terminal block through a hole or slot 44 (Figure 3) in the ground plate and into a recess in the other terminal block to hold the terminal blocks 30a and 30b to the plate of ground 32 as a substation. Once this subassembly is inserted into the passage 31 in the housing 12 as illustrated in Figure 2, the terminal blocks are effective to hold the ground plate between them. The terminal module is maintained within the dielectric housing by ramp locks 36 in each terminal block. Each terminal block 30a and 30b is over-molded at least with respect to a high-speed signal terminal 38. The contact ends of a pair of the terminal 38 together with the forward end of the ground plate 32, are illustrated projecting forward. of the connector in Figure 1, inside the surrounding cover portion 18 of the shield 16. The rear ends 38a of the terminals 38 (Figure 9) are terminated in the core conductor / core 52 of a plurality of coaxial cables, generally designated 40 in Figure 2. The invention is particularly directed in the manner of terminating the metal shields of the coaxial cables in the inner plate 32 as described below.

More particularly, the invention contemplates a two-part termination member that includes a terminal part, generally designated 42 in Figure 3, and a cable receiving part, generally designated 44 in Figures 4 through 6. In fact, the plate ground 32 forms a generally planar elongated blade portion of the terminal portion 42 as clearly illustrated in Figure 3. The ground plate includes the opening 44 (Figure 3) through which the posts 34 (Figure 2) of terminal blocks 30 and 30b extend. The end portion is punched and formed of conductive sheet metal material, and a pair of spikes or teeth 46 are punched at the opposite edges of the ground plate 32 to facilitate holding the sub-assembly of the ground plate. and terminal blocks 30 and 30b within the housing. Finally, a pair of stepped portions 48, project from each opposite side of the ground plate 32 at their opposite edges, to place and receive the part of the cable structure 44 between them in the direction of the arrow "A" (Figure 3). With reference to Figures 4 to 6, the receiving part of the cable 44 is also punched in shape from conductive sheet metal material. Figure 4 shows a pre-for a, generally designated "B" stamped from conductive sheet metal material and from which the cable receiving part is formed. The preform includes an elongated planar base 50 having longitudinally projecting end portions 52.

The end portions will form spring jaws of the cable receiving part as will be seen below. A pair of fins 54 project laterally outward from each side of the base 50 of the prefor to "B". These fins will form the positioning and securing arms of the cable receiving part, as will be seen later. Each arm 54 has a slot 56 for purposes described below. When a coaxial cable shield is attached to the cable receiving part 44 by welding, it is convenient to use a soldering iron having a relatively small tip. Although it is convenient to dimension the grooves 56 sufficiently wide to facilitate adequate welding flow through a groove, it should be narrow enough to avoid between the relatively small tip of the soldering iron contact the coaxial cable shield, which may result in damage to the cable. underlying dielectric of the cable. Each slot 56 is in the order of approximate width of .1016 cm (.040") although it is considered that this slot may be in the range of .0254 to .2794 cm (.010 to .110") in width. The die-cut preform "B" (Figure 4) is formed in the cable receiving part 44 as illustrated in Figures 5 and 6. It can be seen that the base 50 has been bent or formed intermediate to its opposite ends, in such a way that the end portions 52 now form a pair of opposed spring or spring jaws. The tips of the spring jaws are flared outward to define a mouth 58 therebetween. Fins 54 in the reformer are formed or curled inwards as best seen in Figure 6 to form 4 generally cylindrical receptacles 60. These receptacles are provided to receive four coaxial cables as described below. Therefore, once formed, the cable receiving part 44 is provided with a pair of clamping positioning arms 54 and a pair of receptacles 60 on each opposite side of the jaws 52. When assembling, the mouth 58 between the jaws it receives a trailing edge 62 (Figure 3) or ground plate 32 of the terminal part 42 as will be seen below. With this structure, the two-part termination member can terminate from one to four coaxial cables depending on the connector specification. In some computer applications, three wires can be used to carry the red, green, and blue color signals for a monitor. A fourth cable can be used for flat screen monitors to carry the clock signals of pixel clock. Figure 7 shows the cable receiving part 44 which is terminated by four coaxial cables 40. At this point, it will be understood that each coaxial cable 40 is of a conventional construction since each cable includes a central conductor or core 64 surrounded by an internal dielectric type tube 66. A metallic shield in the form of a tubular metallic fabric 68 surrounds the inner dielectric 54. An insulating liner 70, such as plastic or the like, surrounds the metal fabric 68 to form the total composite coaxial cable 40. Figure 7 also shows the core / center conductor 64 of each coaxial cable 40 that is has detached to expose a particular length that will be welded, welded or otherwise attached to the inner end 38a of one of the terminals for high speed signal transmission 38 (Figures 2 and 9). The outer insulating cover 70 of each cable has also been cut back to expose a determined section of the respective metallic shield 68. Therefore, the exposed shield can be welded to a respective one of the positioning and holding arms 54 of the part cable receiver 44 as discussed below. Figure 7 shows the prepared coaxial cables that are inserted in proper alignment within the receptacles 60 of the arms 54, with the metal shields exposed from the cables aligned with the arms. The next stage in processing the terminal module which consists in forming or slightly folding the clamping arms 54 of the cable receiving part 44 in clamping engagement with the coaxial cables with respect to the exposed metal shields as illustrated in Figure 7. There will be it being understood that the clamping arms do not fold over the metal shields as is typical in the folding technique. On the contrary, a quantity of folding force is used to slightly form the clamping arms inwards, in order to only hold or retain the coaxial cables before welding. The folding or clamping pressure should not be excessive which can deform or damage the underlying inner dielectric material 66 of the wires 40 in any proportion, which can affect its electrical performance. The cable receiving part 44 is then mechanically and electrically connected to the metal shields 68 of the coaxial cables by welding the metal shields to the clamping arms 54 by welding through the slot 56 in the clamping arms as in "S" "in Figure 7. As stated above, the slots are formed in the order of .1016 cm (.040") wide, to avoid the application of concentrated heat directly to the metal shields, which can cause thermal damage to the Underlying interior dielectric material The grooves should be narrow enough to at least prevent any tool or soldering iron that was used from passing through the slots and a direct coupling with the metal shield This coupling can result in damage to the underlying interior dielectric. In essence, the grooves restrict the amount of welding heat that is transmitted inward to the inner dielectric material. side, with the grooves extending in a circumferential direction as illustrated, the grooves provide a large circumferential area of access to the metal shields in a circumferential direction. Preferably, each slot extends at least approximately 180 ° around the respective coaxial cable. Alternatively, it is considered that by using a coaxial cable having an internal dielectric that can withstand relatively high temperatures without deformation or degradation (such as aerated teflon) it may be possible to eliminate the slot 56 in the clamping arms 54. In that In this case, welding will have to be applied on the front or rear edges (or both) of the arms where the metal shields 68 contact. Still in another alternate embodiment, the arms 54 again will not include the slots 56 and some means will be employed in the interior surface of the arms 54 for applying welding between the arms and the metal shields 68. These means may include a tin / lead coating, an upper welding coating or a welding insert on the inner surfaces of the arms 54. The outer surfaces of the arms will be heated with a soldering iron or other tool, which can cause the coating, upper coating and welding or welding insert flow, interconnecting the inner surface of the arms to the metallic shields. Once the coaxial cables 40 are mechanically and electrically connected to the cable receiving part 44 as illustrated in Figure 7, the cable receiving part is mounted to the trailing end of the terminal portion 42 as illustrated in Figure 8. This is achieved by sliding the cable receiving part over the terminal part in the direction of arrow "A" (figure 3). The trailing edge 62 (Figure 3) of the ground plate 32 enters the mouth 58 (Figure 5) between the clamping jaws 52 of the cable receiving part. Positioning arms 48 projecting from the ground plate, suitably position the cable receiving part laterally of the terminal part as the spring jaws 52 hold opposite sides of the ground plate 32. If necessary, the two parts can be welded permanently together by applying welding connections between spring jaws 52 of the receiving part of the cable 44 and the ground plate 32 of the terminal part 42. Once the sub-assembly of Figure 8 is manufactured, including the procedures of welding, this sub-assembly is assembled to terminal blocks 30a and 30b, including high-speed signal transmission terminals 38 to form the terminal module 30 as illustrated in Figure 9 and described above with reference to Figure 2. Nucleus / central conductors 52 of the coaxial cables are then connected by welding, welding or otherwise holding the ends 38a of the terminals 38, while the terminal blocks 30a and 30b clamp the ground plate 32 of the terminal part 42 therebetween, as illustrated in Figur * 2 and described above. The terminal module is then mounted within the dielectric housing 12 as illustrated in Figure 2. If desired, the blocks 30a and 30b can be mounted to the ground plate 32 of the terminal portion 42 before mounting the cable receiving portion 44. above. In other words, the ground plate 32 illustrated in the Figure will have the terminal blocks mounted at the beginning of the termination process. The concepts of the invention have been illustrated and described here in conjunction with terminating the metal shields of the coaxial cables 40 to a two-part termination member including the ground plate 32. However, it will be understood that the concepts of the invention they are equally applicable for terminating metal shields to other types of termination members, such as individual electrical terminals. It will be understood that the invention can be incorporated in other specific forms without departing from the spirit or central feature thereof. The present examples and embodiments thereof shall be considered in all respects as illustrative and not restrictive and the invention is not limited to the activated details.
