Description

ES $ SYSTEM FOR THE TERMINATION OF THE PROTECTION OF A HIGH-SPEED CABLE Field of the invention The invention is generally related to the technique of electrical connectors and, particularly, to a system for the termination of the metallic protection of a high-speed cable. speed, such as a metallic cable braid. BACKGROUND OF THE INVENTION A typical high speed cable includes a core or central conductor surrounded by an internal dielectric element similar to a tube. A screen or protection is disposed outside the internal dielectric element to protect and / or ground the cable. The shield or screen is typically a tubular metal braid. However, one or more longitudinal conductive wires have also been used and are commonly referred to as "consumer wires". An insulating jacket surrounds the composite cable to the outside of the shield. Various types of connectors are used for the termination of high-speed cables. The connectors typically have contacts that are terminated in the core or center conductor of the cable. The connectors also have one form or another of a termination member to terminate the metal shield of the high speed cable, usually for grounding purposes. A typical system for such connectors terminate the metallic protection in the termination member by welding. Other systems use bending procedures to bend at least a portion of the terminating member securely to the metal interlock for common purposes. With the ever increasing miniaturization of electronic elements in various industries, such as in the computer and telecommunications industries, along with mini-whirling accompanied by electrical connectors, considerable problems have been encountered in terminating high-speed miniature cables, particularly for the termination of the protection or metallic screen of the cable. For example, the external diameter of a small coaxial cable may be in the order of 0.22 cm (0.090 inch). The outer diameter of the internal dielectric element surrounding the core / conductor may be in the order of 0.12 cm (0.051 inch), and the diameter of the core / central conductor may be in the order of 0.030 cm (0.012 inch). Coaxial cables have been used that still have smaller dimensional parameters. The problems for the termination of such very small coaxial cables often revolve around the termination of the metallic protection of the cable. For example, in case welding methods are used, applying heat (necessarily for welding) in a direct proximity to the metal shield, the heat can cause damage to the underlying internal dielectric element, in effect, substantially disintegrates or degrades the dielectric element internal. If conventional bending type terminations are used, typical bending forces often crush or deform the internal dielectric element surrounding the core / center conductor of the cable. The above problems are further complicated when the metallic protection of the high speed cable is not terminated with a cylindrical termination member, but the protection is terminated in a flat termination member or contact. For example, this is known to terminate the tubular or braided metal protection of the coaxial cable in a dimmer with a flat grounding circuit on a printed circuit board. This is often accomplished by simply providing the tubular metal braid of the coaxial cable in a "flexible connecting cable" or twisted strand, which, in turn, is soldered to the flat ground attenuator in the circuit board.

Another example of the termination of the metal braid or protection of a coaxial cable in a flat grounding member is shown in US Pat. No. 5,304,069, dated April 19, 994 and assigned to the assignee of the present invention. In this patent, the metallic braids of a plurality of coaxial cables are terminated in a grounding plate of a high speed signal transmission terminal module. The conductors / cores of the coaxial cables are terminated at the terminals of the module signals. In the termination of tubular metal braids or braids of high-speed cables in flat grounding contact attenuators such as in a printed circuit board, or in a flat grounding plate as referenced above in the Patent of the USA, or in any other flat or non-tubular termination member, the present invention has found various considerations about the designs considered. It will be understood that there is a transition zone created where the central core / conductor of the high speed cable goes from a "controlled environment" where the core / conductor is completely surrounded by a tubular metal braid or protection, in an "environment not controlled ", wherein the braid is extended away from the core / conductor for termination in the non-tubular termination member. It is desirable that this transition zone be maintained as small an area as possible and as short a length as possible (ie, lengthwise of the cable). Preferably, the metallic braid or protection will be terminated over an area (or at least two points) approximately 180 ° apart, relative to the core / center conductor of the cable. Preferably, the flat termination member will overlap or at least extend to the point where the metal shield or braid is separated from its tubular configuration surrounding the core / conductor of the cable. It is still further desirable that the metal braid or protection of any given high speed cab 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 solve many of the problems identified above and to satisfy many of the design parameters identified above as possible in an improved system for the termination of the metal shield. of a high-speed cable in a termination member, such as a grounding plate. Therefore, an object of the invention is to provide a novel and improved system or terminal for the termination of the metallic protections of a plurality of high-speed cables. In the exemplary embodiment of the invention, a terminal for termination of the protections of a plurality of high-speed cables is disclosed, each having an outer jacket and an internal metal shield with a portion of an outer jacket removed to expose a portion of the metal protection. The terminal includes a portion of the conductive ground connection plate. A clamping arm projects from the portion of the grounding plate to comprise the plurality of high speed cables in a direct coupling with the exposed portions of its metal shields. A welding connection is arranged between the clamping arm and the metal protections. As disclosed herein, the grounding plate is generally flat, and the clamping arm projects inwardly from one edge of the grounding plate. Preferably, a pair of clamping arms project from the opposite sides of the grounding plate, with the clamping arms projecting inwardly from the opposite edges of the grounding plate. In the preferred embodiment, each clamping arm is contoured to cooperate with the grounding plate to define the discrete chambers to respectively receive the plurality of high speed cables. Specifically, each clamping arm is corrugated to define generally semi-cylindrical portions to respectively comprise the plurality of high-speed cables. In an embodiment of the inventionEach clamping arm includes an opening for receiving the welding connection therethrough. In the preferred embodiment, the opening is a circumferentially extending slot. The slot is in the order of 0.10 cm (0.040 inches). In another embodiment, the welding connection is disposed inside the clamping arms by a welding material that has been deposited therein and subsequently turned to flow. Preferably, the welding material is deposited as an inlay on the inside of the clamping arms. Other objects, features and advantages of the invention will become apparent with the following detailed description taken in connection with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS The characteristics of this invention that are considered to be novel are described with particularity to the ar.exas claims. The invention, together with its objects and its advantages, can be better understood with reference to the following description taken in conjunction with the accompanying drawings, in which like reference numbers identify similar elements in the figures and in which: Figure 1 is a perspective view of an electrical connector of the type in which the invention is applicable; Figure 2 is a fragmented vertical section taken generally along line 2-2 of Figure 1; Figure 3 is a plan view of a projected form of metal from which the terminal or the grounding plate is formed; Figure 4 is a perspective view of the grounding plate with the clamping arms partially formed to receive the coaxial cables; Figure 5 is a perspective view of a grounding plate formed with a pair of coaxial cables placed therein, and with the cables prepared when removing the portions of the outer jackets to expose the metal shields; Figure 6 is a view similar to that of Figure 5, but showing four coaxial cables placed on the grounding plate; Figure 7 is a perspective view of the terminal module mountable in the connector of Figures 1 and 2; and Figure 8 is a view similar to that of Figure 7, but showing an alternative embodiment of the invention, wherein the welding material is embedded within the holding arms. With reference first to the drawings and in greater detail to Figures I and 2, the invention is included in a protected or shielded electrical connector, generally designated 10, which is a hybrid electric connector for terminating both the transmission line conductors of the slowest data and the drivers of the high speed or high frequency transmission lines. In particular, the electrical connector 10 includes a dielectric housing 12 (Figure 2) that mounts a plurality of data transmission terminals 14 (Figure 1). A conductive shield, generally designated 16, substantially surrounds the dielectric housing 12 and has a bushing portion 18 projecting forward about the corresponding ends of the data transmission terminals 14. A two-piece counter-cap (not shown) of substantially consistent with what is shown in the US Patent No. 5,358,428 dated October 25, 1994, is projected backwardly of the housing 12 and of the shield or screen 16. A molded sleeve 20 includes a strain relief element of the integral wire 22 which is in engagement with a cable Compound 24, which includes both data transmission lines and high-speed and high-frequency transmission lines. A pair of wing or butterfly screws 26 projects through the molded sleeve and includes externally threaded front distal ends 26a to secure the connector to a connector, panel or other complementary corresponding structure. As best seen in Figure 2, a high-speed signal transmission terminal module, generally designated 30, is inserted into a passage 31 in a dielectric housing 12 from the rear thereof. The terminal module includes a pair of identical terminal blocks 30a and 30b, which hold a grounding plate, generally designated 32, between them. Each terminal block includes a post 34 and a recess. The post of each terminal block extends from each terminal block through a hole or slot 44 (Figure 3) in the grounding plate and into a recess in the other terminal block to secure the terminal blocks 30a and 30b to the grounding plate 32 as a subassembly. Once this subassembly is inserted into the passage 31 in the housing 12 as shown in Figure 2, the terminal blocks are effective to hold the grounding plate between them. The terminal module is held within the dielectric housing by ramp or inclined locks 36 in each terminal block. Each terminal block 30a and 30b is over-molded around at least one high-speed signal terminal 38. The contact ends of a pair of terminals 38, together with the front end of the grounding plate 32 are shown projecting towards in front of the connector in Figure 1, inside the surrounding castellate portion 18 of the shield or screen 16. The rear ends 38a of the terminals 38 (Figure 7) are terminated in the central cores / conductors 52 of a plurality of coaxial cables , generally designated 40 in Figure 2. The invention is particularly directed to the shape of the terminations of the metal protections 56 of the coaxial cables in the grounding plates 32 as described below. More particularly, Figure 3 shows a proforma, generally designated "B", punched out of a conductive sheet metal material and from which the grounding plate 32 is formed. The proforma "B" is generally confi rmed in "T". "and includes a leg or rod portion 42, which will form a blade portion for the ground connection plate 32. The blade portion includes an opening 44 through which the posts 34 (FIG. terminal blocks 30a and 30b. A fin or arm 46 projects outwardly at one end of the leg 42, usually on each opposite edge of it. These fins will form the clamping arms of the grounding plate, as will be noted hereinafter. Each fin or clamping arm has an elongated slot 48 for facilitating the weld termination described hereinafter. When the cable shield 56 is welded to the grounding plate 32, it is desirable to use an iron weld having a relatively small tip. Although it is desirable to dimension the groove wide enough to facilitate the proper flow of weld through the groove, it should be narrow enough to prevent a relatively small iron welding tip from coming into contact with the shield or braid 56 of the wire , which can cause damage to the internal dielectric element 62. Each slot is in the order of approximately 0.10 cm (0.040 inches) in width, although it is considered that such a slot may be within the range of 0.27 cm to 0.25 cm (0.110). to 0.010 inches) wide. Finally, the teeth or prongs 49 are punched out at the opposite edges of the portion of the blade 42 to facilitate holding the sub-assembly of the grounding plate and the terminal blocks 30a and 30b within the housing. As will be seen hereinafter, once formed the ground connection plate 32 is provided with a positioning and securing arm on each side of the grounding plate to place and hold a pair of coaxial cables. The arms are located at the extreme rear distal end of the blade portion 42. With this structure, the grounding plate can terminate with one to four coaxial cables depending on the specifications of the connector. In some computer applications, three wires can be used to carry green and blue signals to the network for a monitor. A fourth cable can be used for flat screen monitors to carry the clock signals of pixel clock. Figure 4 shows the die-cut projection "B" of Figure 3 with fins 46 that have been bent inward to form a generally designed positioning and fastening arm 50a and a positioning and fastening arm, generally designated 50b. Each clamping arm is contoured in a corrugated configuration to define a pair of semi-cylindrical portions 52, which cooperate with the blade portion 42 to define discrete chambers 54 for receiving a plurality of coaxial cables, as described hereinbelow hereinafter . It can be seen that, after being formed, the slots 48 in the arms extend in a circumferential direction, around the portions of each chamber 54. It can also be seen that each grip arm extends fully through the blade portion. 42, leaving only a very small space 56 between the distal end of the arm and the blade portion. Therefore, the coaxial cables are completely surrounded substantially by the clamping arms and the blade portions 42. With this structure, the grounding plate can terminate with one to four coaxial cables depending on the specifications of the connector. Figure 5 shows the grounding plate 32 formed of Figure 4 with a pair of coaxial cables 40 positioned within the chambers 54 of the upper clamping arm 50a. At this point, it will be understood that each coaxial cable 40 is of a conventional construction, since each cable includes a core or central conductor 60 surrounded by an internal dielectric element similar to a tube 62. A metallic shield in the form of a metallic braid tubular 64 surrounds the internal dielectric element 62. An insulating jacket 66, like plastic or the like, surrounds the metallic braid 64 to form the entire composite coaxial cable 40. Figure 5 also shows that the core / center conductor 60 of each cable coaxial 40 has been unprotected to expose a given length thereof, which will be welded to the inner end of one of the high-speed signal transmission terminals 38 (Figure 7). The external insulating jacket 66 of each cable has also been recessed to expose a given length of the respective metal shield 64. Therefore, the exposed protection can be welded to the clamping arms 50a or 50b of the grounding plate 32 , as discussed below. As mentioned, Figure 5 shows the clamping arms 50a and 50b in position to receive the coaxial cables 40 prepared as described above. Figure 5 shows two coaxial cables 40 placed within the upper clamping arm 50a in a lengthwise manner, so that the metallic protections 64 of the cables are in register with the clamping arm in the internal part thereof. Each coaxial cable is positioned longitudinally within one of the chambers 54 defined by the half-cylindrical portions 52. The coaxial cables can be placed within the clamping arm by a slight pressure adjustment. Alternatively, the clamping arms can be formed initially to freely receive the coaxial cables longitudinally therein, whereas the only initial function of the arms is the placement of the cables, and subsequently, the arms can be further formed to positively clamp the coaxial cables and having completely closed spaces 56. In such an embodiment, the free end of the clamping arms 50a and 50b may include some type of latch (not shown) for coupling or overlaying a portion of the grounding plate 32 or the other arm of clamping in order to completely enclose the coaxial cable. It will be understood that the clamping arms are not bent over the metal guards as is typical in the bending technique. Instead, a quantity of force is used to lightly form the clamping arms inwards, solely for the purpose of holding and retaining the coaxial cables before welding. The clamping or bending pressure shall not be excessive in order not to damage the underlying internal dielectric material 62 to any degree, which may affect its electrical performance. The grounding plate 32 is then connected mechanically and electrically to the metallic protections 64 of the coaxial cables when welding the metal protections to the clamping arm 50a when applying welding through the slot 48 in the clamping arm, as in " S "in Figure 5. As mentioned above, the slots are formed in the approximate order of 0.10 cm (0.040 inches) in width to prevent the application directly from the concentrated heat to the metal shield, whose heat may cause damage to the element underlying internal dielectric. The groove will at least be narrow enough to prevent any iron solder or used tool from passing through the groove and this in a direct coupling with the metal shield. Such coupling can cause damage to the underlying internal dielectric element. In essence, the slots restrict the amount of heat to be welded, which is transmitted inwardly to the internal dielectric element. On the other hand, the grooves extend in a circumferential direction to provide a large circumferential area of access to the metal guards in a circumferential direction. Once the two coaxial cables 40 are welded to the upper clamping arm 50a as shown in Figure 5, the grounding plate 32 is inverted as shown in Figure 6 and another pair of coaxial cables is inserted into the Chambers 54 of the other clamping arm 50b and is welded thereto, as described above in relation to Figure 5. Once the subassembly of Figure 6 is manufactured, including the welding procedures, this subassembly is assembled in the terminal blocks 30a and 30b including high-speed signal transmission terminals 38 for forming the terminal module 30 as shown in Figure 7 and as described above in relation to Figure 2. The central cores / conductors 60 of the coaxial cables are then connected, by welding or other means to be secured to the inner ends 38a of the terminals 38, while the terminal blocks 30a and 30b clamp to the portion of the cable. uchilla 42 of the grounding plate 32 therebetween, as shown in Figure 2. If desired, the terminal blocks 30a and 30b can be mounted on the blade portion 42 of the grounding plate 32 prior to inserting the cables 40 into the holding arms 50a and 50b. In other words, the grounding plate 32 will have the terminal blocks mounted therein at the beginning of the termination process. Figure 8 shows an alternative embodiment of the invention, wherein the slots 48 have been removed and the welding material is deposited or embedded in the internal part of the clamping arms 50a and 50b as indicated by the dotted lines 70 and subsequently they return to flow during the welding process. Once the clamping arms are formed as shown in Figure 8, the embedded welding material is not visible to the outside of the structure. During processing, after the coaxial cables are inserted into a position within the clamping arms, and with the metal clamps in register with the arms, the embedded welding material is heated and flows again to mechanically and electrically connect the clamping arms to the metal protections of the coaxial cables. In the alternate mode, it is considered that by using coaxial cables having internal dielectric elements that can withstand relatively high temperatures without deforming or degrading, it may be possible to eliminate the slots 48 or scale 70 in the clamping arms 50a and 50b. In this case, the welding will be applied along the guide or exit edges (or both) on the arms where they are in contact with the metal protections. The concepts of the invention have been shown and described herein in conjunction with the termination of the metal shields of a plurality of coaxial cables in a termination member, in the form of a grounding plate. However, it will be understood that the concepts of the invention are equally applicable for terminating metal protections with other types of termination members, such as the same individual electrical terminals. It will be understood that the invention can be included in other specific forms without departing from the spirit or central characteristics thereof. Therefore, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention will not be limited by the details provided herein.
