Description

Technical Field

[0001] The present invention relates to a cable component and a cable connector, belonging to the technical field of electrical connection devices. Background Art

[0002] Traditional ultra-micro rectangular connector plug contacts utilize twisted wire pins, which require a complex molding process. In response, Chinese invention patent application publication number CN114243367A discloses a compact contact and an ultra-micro rectangular electrical connector utilizing the same. The ultra-micro rectangular electrical connector comprises a plug and a receptacle. The plug includes a header housing, a pin insulator, a tooth spring pin, and a connecting cable. The connecting cable is crimped to the tooth spring pin, which is then inserted into the pin insulator. The pin insulator is then installed into the header housing. After the pin insulator is installed, the header housing is encapsulated with black resin glue to secure the connecting cable and pin insulator to the header housing. The receptacle has a similar structure, with the fixed cable also crimped to the crimping jack.

[0003] The above-mentioned tooth spring pins (i.e., plug terminals) are not in the form of twisted wires, and the molding process is simpler. However, whether it is a plug terminal or a crimping socket (i.e., a socket terminal), since the specifications of the terminals are relatively small, the specifications of the wire barrel crimped with the wire are also small, and the wire inserted into the wire barrel needs to be adapted to the wire barrel, which limits the specifications of the wires that can be connected to the terminals.

[0004] In this regard, the Chinese invention patent application, publication number CN113422255A, discloses a high-speed, ultra-fine coaxial connector assembly comprising a male connector and a female connector. The male connector comprises a male shield shell, a male insulator, male terminals, and a coaxial cable. The male terminals are injection-molded and fixed in a row within the male insulator. One end of the male terminals is a wiring terminal, and the other end has a plug-in terminal. The core of the coaxial cable is welded to the wiring terminal surface of the male terminal. Simultaneously, the shielding layers of all coaxial cables are welded between the upper and lower conductive strips, which are filled with solder to achieve common ground connection for the shielding layers of all coaxial cables.

[0005] The connection terminal surface of the above-mentioned male terminal (i.e., signal terminal) is welded to the core of the coaxial cable, which can adapt to a wide range of cable specifications. The coaxial cable contains a shielding layer, which ensures good shielding effect between cables. However, there is still relatively large crosstalk between the signal terminals, causing the connector to be unable to meet the requirements of higher transmission rates. Summary of the Invention

[0006] The object of the present invention is to provide a cable component to solve the problem that the crosstalk between the signal terminals of the existing connector is relatively large and cannot meet the requirements of higher transmission rates; the object of the present invention is also to provide a cable connector to solve the above problems.

The cores of each coaxial cable are respectively welded and fixed to the core welding planes of the corresponding signal terminals. Grounding terminals are injection-molded and fixed on the sides of each signal differential pair in the module insulator. The ends of the grounding terminals have common ground welding planes. The conductive strip includes a strip-shaped base and multiple cantilevers connected to the strip-shaped base. The cantilevers are welded and fixed one by one to the common ground welding planes of the grounding terminals.

[0018] The beneficial effect of the above technical solution is that: the present invention is an improved invention, and the improvement is that grounding terminals are injection-molded and fixed on the side of each signal differential pair in the module insulator, and the end of the grounding terminal has a common ground welding plane. The conductive strip includes a strip base and a plurality of cantilevers connected to the strip base. Each cantilever is welded and fixed on the common ground welding plane of the ground terminal in a one-to-one correspondence, so that each grounding terminal and the shielding layer of each coaxial cable are connected to the common ground through the conductive strip. In this way, the grounding terminals next to the signal differential pair can effectively improve the crosstalk between the signal terminals, so that the connector can meet the requirements of higher transmission rates.

[0030] In response to the technical problems existing in the prior art, the basic concept of the present invention is to set a ground terminal next to the signal differential pair, and use a conductive strip to achieve common ground connection between each ground terminal and the shielding layer of each coaxial cable, thereby improving the crosstalk between the signal terminals and enabling the connector to meet the requirements of higher transmission rates.

[0031] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0032] Example 1 of the cable connector of the present invention: like Figure 1 and Figure 2 As shown, the cable connector in this embodiment is an ultra-micro rectangular receptacle connector, comprising a housing and at least one cable component mounted within the housing. Specifically, the housing comprises an outer housing 1 and an inner housing 2 positioned within the outer housing 1. A receptacle insulator 3 is disposed within the inner housing 2, and the cable component is mounted on the receptacle insulator 3. In this embodiment, there are four cable components: two straight cable components 100 and two curved cable components 200. The two straight cable components 100 are arranged closely together, while the two curved cable components 200 are symmetrically arranged on either side of the two straight cable components 100.

[0033] The structures of the straight cable component 100 and the curved cable component 200 are basically similar, and the main difference lies in the shape of the terminals. The terminals in the straight cable component 100 are straight terminals 110 extending in a straight line, while the terminals in the curved cable component 200 have a bent portion and are curved terminals 210 extending in a Z shape. The straight cable component 100 is used as an example for explanation below.

[0034] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, a straight cable assembly 100 includes a terminal module and multiple coaxial cables 10 connected to the terminal module. The terminal module includes a module insulator 7 and multiple signal terminals 8 and multiple ground terminals 9 injection-molded and fixed within the module insulator 7. The signal terminals 8 are arranged in pairs to form signal differential pairs. The ground terminals 9 are located next to the signal differential pairs and are also arranged in pairs. That is, there are two ground terminals 9 between two signal differential pairs. Each signal terminal 8 and each ground terminal 9 is a straight terminal 110 as described above. For the four cable assemblies, each pair of signal terminals 8 is directly opposite a pair of ground terminals 9 to ensure shielding.

[0035] Combine Figure 10 As shown, each signal terminal 8 includes a signal strip 81. The strip routing is relatively uniform, which can ensure impedance continuity. One end of each signal strip 81 is exposed from the module insulator 7 to form a cable connection end, and the other end is also exposed from the module insulator 7 and connected to a signal round pin 82. The cable connection end has a core welding plane 811, and the core 104 of the coaxial cable 10 is welded and fixed on the core welding plane 811. Figure 5 As shown, the coaxial cable 10 in this embodiment is an ultra-fine coaxial cable with a specific specification of 36AWG, which includes an outer sheath 101, a shielding layer 102 located inside the outer sheath 101, an insulating layer 103 located inside the shielding layer 102, and a core 104 located inside the insulating layer 103. The ultra-fine coaxial cable has a shielding function and can transmit long-distance, high-speed differential signals.

[0036] like Figure 10 As shown, each grounding terminal 9 includes a grounding strip 91. One end of each grounding strip 91 is exposed from the module insulator 7 to form a common ground connection end, while the other end is also exposed from the module insulator 7 and connected to a grounding round pin 92. Furthermore, the grounding strips 91 of a pair of grounding terminals 9 are connected by a connecting structure 93, which improves shielding and enhances the high-speed transmission performance of the cable connector.

[0037] The common ground connection end has a common ground welding plane 911, and the ends of each wire core welding plane 811 and each common ground welding plane 911 are aligned, and each wire core welding plane 811 and each common ground welding plane 911 are coplanar. Figures 3 to 6As shown, the straight cable assembly 100 also includes conductive strips that are electrically conductive to the shielding layer 102 of each coaxial cable 10. In this embodiment, the conductive strips include an upper conductive strip 13 and a lower conductive strip 15 located on the upper and lower sides of the shielding layer 102 of each coaxial cable 10. The upper conductive strip 13 includes a strip-shaped base 131 and a plurality of cantilevers 132 connected to the strip-shaped base 131. Each cantilever 132 is elastic and can elastically deform relative to the strip-shaped base 131. The cantilevers 132 are also arranged in pairs, corresponding to the paired ground terminals 9. Each cantilever 132 is welded to the common ground welding plane 911 of the ground terminal 9, achieving common ground conductivity between the shielding layer 102 of each coaxial cable 10 and each ground terminal 9. The ground terminal 9 can effectively reduce crosstalk between the signal terminals 8, thereby further improving the shielding effect and enabling the cable connector to meet higher transmission rate requirements.

[0038] The module insulator 7 is formed with positioning protrusions arranged at intervals along the arrangement direction of the signal terminals 8 and the ground terminals 9. The positioning protrusions are located at the ends of the signal strip 81 and the ground strip 91, and there are positioning protrusions on both sides of each core welding plane 811. A core passage space for the core 104 of the coaxial cable 10 to pass through is formed between the positioning protrusions on both sides of the core welding plane 811. In this way, when the coaxial cable 10 is placed, the position of the core 104 can be located to facilitate the welding operation.

[0039] At the same time, there are the aforementioned positioning protrusions on both sides of each common welding plane 911, and a cantilever passage space for the cantilever 132 to pass through is formed between the positioning protrusions on both sides of the common welding plane 911. In this way, when the conductive strip 13 is installed, the position of the cantilever 132 can be positioned, thereby facilitating the welding operation.

[0040] Furthermore, a positioning protrusion is shared between the common ground welding planes 911 of a pair of ground terminals 9, between the core welding planes 811 of a pair of signal terminals 8, and between adjacent common ground welding planes 911 and core welding planes 811, respectively. This can simplify the structure and make the spacing between the terminals as small as possible.

[0041] Furthermore, at least two of the positioning protrusions are long positioning protrusions 71, and the rest are all short positioning protrusions 72. The length of the long positioning protrusions 71 is greater than that of the short positioning protrusions 72. The lengths of the long positioning protrusions 71 and the short positioning protrusions 72 are consistent. One end of the length direction of each long positioning protrusion 71 is aligned with the end of each wire core welding plane 811 and each common ground welding plane 911, and the other end of the length direction of each long positioning protrusion 71 extends beyond the end of each wire core welding plane 811 and each common ground welding plane 911. The strip-shaped base 131 and the lower conductive strip 15 are blocked by the long positioning protrusions 71. In this way, when installing the upper conductive strip 13 and the lower conductive strip 15, the long positioning protrusions 71 can be used for positioning to prevent the two conductive strips from being too close to the signal terminal 8.

[0042] Furthermore, a long positioning protrusion 71 is provided between the common ground welding plane 911 of each pair of ground terminals 9, and the positioning protrusions on both sides of each core welding plane 811 are short positioning protrusions 72. With this arrangement, firstly, the long positioning protrusions 71 are evenly spaced, which provides a better blocking effect on the upper conductive strip 13 and the lower conductive strip 15. Secondly, the long positioning protrusions 71 are sandwiched between a pair of cantilever arms 132. Compared with the short positioning protrusions 72, the long positioning protrusions 71 have a larger contact area with the cantilever arms 132, which can better block the cantilever arms 132 and prevent them from deforming or moving during the welding process.

[0043] Furthermore, since the coaxial cable 10 has a certain diameter, when the upper conductive bar 13 is placed on the shielding layer 102 of each coaxial cable 10, the upper conductive bar 13 is higher than the common ground welding plane 911, so each cantilever 132 extends downward at an angle. On this basis, the height of each long positioning protrusion 71 is greater than the height of each short positioning protrusion 72, which makes the contact area between the long positioning protrusion 71 and the cantilever 132 larger, thereby improving the blocking effect.

[0044] In addition, the lower conductive bar 15 and the upper conductive bar 13 are both made of copper sheets. The shielding layer 102 of the coaxial cable 10 is sandwiched between the strip-shaped base 131 of the upper conductive bar 13 and the lower conductive bar 15. A receiving groove 74 for accommodating the lower conductive bar 15 is formed on the module insulator 7. The other end of the long positioning protrusion 71 in the length direction extends into the receiving groove 74. When the lower conductive bar 15 is placed in the receiving groove 74, the other end of the long positioning protrusion 71 in the length direction cooperates with the lower conductive bar 15 to stop it, so that the installation of the lower conductive bar 15 can be positioned so that it maintains a certain distance from the signal terminal 8.

[0045] The strip base 131 of the upper conductive bar 13 and the lower conductive bar 15 are connected to the shielding layer 102 of each coaxial cable 10 through welding. The strip base 131 of the upper conductive bar 13 and the lower conductive bar 15 are filled with molten metal 14. The molten metal 14 is specifically solder. The solder is filled between the strip base 131 and the lower conductive bar 15, which not only improves the common ground conduction effect, but also avoids excessive solder contact with the module insulator 7, thereby avoiding local overheating of the module insulator 7 and causing deformation.

[0046] In addition, if Figure 3 As shown, the straight cable component 100 also includes an insulating glue 12 coated and fixed on the outside of the welding part between the core 104 and the core welding plane 811 and the outside of the welding part between the cantilever 132 and the common ground welding plane 911, so as to form protection for the welding part, and the insulating glue 12 is transparent glue for easy observation.

[0047] Each signal terminal 8 and each ground terminal 9 is stamped and formed using a single die. To facilitate electroplating, a connecting structure is retained between the signal terminals 8 and between the signal terminals 8 and the ground terminals 9 after initial stamping. Connecting structures are not provided at the ends of the terminals; the connecting structure is located in the middle of the strip. A cutting window 73 is formed in the module insulator 7 to expose the connecting structure between a pair of signal terminals 8 and the connecting structure between a signal terminal 8 and an adjacent ground terminal 9 after injection molding, allowing the connecting structure to be cut, thereby enabling the connector's basic signal transmission function. Of course, the connecting structure 93 between the pair of ground terminals 9 is also exposed, but does not need to be cut.

[0048] like Figures 3 to 5 、 Figure 7 and Figure 8 As shown, the terminal module further includes a socket contact 11 connected to the outside of each signal extruded round pin 82 and each ground extruded round pin 92. Figure 9 As shown, the receptacle contact 11 is manufactured by stamping and rolling, and includes a receptacle section 111 and a sleeve section 112 connected to the receptacle section 111. The receptacle section 111 is used to insert and electrically connect the pin contact of the adapter connector. The sleeve section 112 is mounted outside the signal extruded round pin 82 and the ground extruded round pin 92. The overlapping areas with the signal extruded round pin 82 and the ground extruded round pin 92 are laser welded to ensure fixation and electrical connection. Furthermore, the sleeve section 112 is provided with barbs 113, which are designed to interference fit with the mounting holes in the receptacle insulator 3, ensuring stable installation between the cable component and the receptacle insulator 3.

[0049] Therefore, the end of the terminal module provided with the socket contact 11 constitutes the plug-in end, and the end provided with the wire core welding plane 811 constitutes the connection end. Then, the straight terminals 110 (including the signal terminals 8 and the grounding terminals 9) in the straight cable component 100 extend in a straight line from the plug-in end of the terminal module to the connection end, and the bent terminals 210 (also including the signal terminals and the grounding terminals) in the bent cable component 200 extend in a Z-shape from the plug-in end of the terminal module to the connection end. Figure 2 As shown, the spacing between the straight terminals 110 and the curved terminals 210 at the terminal module connection terminals is greater than the spacing between the terminal module plug-in terminals. This ensures the proper spacing between the plug-in terminals while arranging the coaxial cables at the connection terminals. Specifically, the coaxial cables connected to the signal terminals 8 in the straight cable assembly 100 are located between the straight cable assembly 100 and the curved cable assembly 200, while the coaxial cables connected to the signal terminals in the curved cable assembly 200 are located on the side facing away from the straight cable assembly 100.

[0050] During the manufacture of the cable connector in this embodiment, the various cable components are first fabricated. For each cable component, the terminal module is first fabricated. The terminals are integrally overmolded with adhesive to form the insulator component. Cutting windows in the module insulator are used to separate the connecting structure between a pair of signal terminals and the connecting structure between a signal terminal and an adjacent ground terminal. The extruded pins of the signal and ground terminals are then assembled with the receptacle contacts. The overlapping portions of the two components are then laser welded together to form a single, welded component.

[0051] Then connect the coaxial cable, taking the straight cable component as an example, such as Figure 5 As shown, the lower conductive strip 15 is placed in the receiving groove 74 of the module insulator 7, and the lower conductive strip 15 cooperates with the end face stop of the long positioning protrusion 71. Then, the core 104 of the stripped coaxial cable 10 is placed on the core welding plane 811. It should be noted that a certain length of the insulating layer 103 needs to be exposed on the rear side of the core 104, and a certain length of the shielding layer 102 needs to be exposed on the rear side of the insulating layer 103. The shielding layer 102 corresponds to the lower conductive strip 15. Then, the upper conductive strip 13 is placed, and the strip-shaped base of the upper conductive strip 13 corresponds to the shielding layer 102, and cooperates with the end face stop of the long positioning protrusion 71. The cantilever 132 of the upper conductive strip 13 overlaps the common ground welding plane 911, and welding is performed between the core 104 and the core welding plane 811, and welding is performed between the cantilever 132 and the common ground welding plane 911, and the deposited metal 14 is filled between the strip-shaped base of the upper conductive strip 13 and the lower conductive strip 15, as shown in FIG. Figure 4 After welding, the insulating glue 12 is applied to the outside of the welding part between the core 104 and the core welding plane 811 and the outside of the welding part between the cantilever 132 and the common ground welding plane 911. Figure 3The bent cable components are the same as above and will not be repeated.

[0052] The next step is to assemble the cable components and combine them Figure 1 and Figure 2 As shown, the straight cable assembly 100 and the curved cable assembly 200 are respectively installed on the socket insulator 3. The jack contacts of the cable assemblies pass through the mounting holes on the socket insulator 3 and form an interference fit with the mounting holes. Assembling one cable assembly completes the installation of a row of terminals, improving assembly efficiency. The socket insulator 3 and the four cable assemblies are then installed together into the inner housing 2, and finally into the outer housing 1. The outer housing 1 is longer than the inner housing 2. Glue is poured at the rear of the outer housing 1, filling the area where the cutting window is located and where the coaxial cables are welded to the terminals, thereby securing and sealing the cable assemblies to the outer housing 1. Finally, a wire clamping plate 5 is installed at the rear of the outer housing 1 using screws 6 to bundle the coaxial cables. Furthermore, a threaded locking assembly 4 is installed on the outer housing 1. When the cable connector is plugged into the adapter connector, the threaded locking assembly 4 can be used to lock the cable connector to the adapter connector.

[0053] It should be noted that the adapter connector can also be a connector for connecting a coaxial cable. The structure of the adapter connector and the connection method with the coaxial cable are the same as the cable connector in this embodiment, in which case it is a wire-to-wire form; of course, the adapter connector can also be a connector for connecting a printed circuit board, in which case it is a board-to-wire form.

[0054] Embodiment 2 of the cable connector of the present invention: like Figure 11 As shown, the difference from Example 1 is that the number of signal terminals 8 and ground terminals 9 is different, and no connecting structure is set between a pair of ground terminals 9. Before injection molding, there is a connecting structure between a pair of signal terminals 8, between the signal terminal 8 and the adjacent ground terminal 9, and between a pair of ground terminals 9. After the injection molding is completed, all the connecting structures are cut off through the cutting window.

[0055] In other embodiments of the cable connector, the cable connector may also be a plug connector, and in this case, the contact piece connected to the rounded pin in the terminal module is a pin contact piece.

[0056] In other embodiments of the cable connector: depending on specific product requirements, there may be only two cable components, all of which are straight cable components. Of course, there may also be only one cable component.

[0057] In other embodiments of the cable connector: the outside of the welding parts of the wire core welding plane and the outside of the welding parts of the cantilever and the common ground welding plane may no longer be coated with fixed insulating glue. After the cable components are installed in the outer shell, the glue poured at the tail of the outer shell can also flow to the outside of the above-mentioned parts.

[0058] In other embodiments of the cable connector: when the spacing between the terminals is large enough and the size of the positioning protrusions is relatively small, there can be two positioning protrusions between two adjacent terminals, that is, the terminals no longer share positioning protrusions, and each terminal is configured with a set of positioning protrusions.

[0059] In other embodiments of the cable connector: after electroplating and before injection molding, all the connected material structures that need to be cut can be cut off, so that no cutting window needs to be reserved on the module insulator during injection molding.

[0060] In other embodiments of the cable connector, the ground terminals may not be arranged in pairs, and there may be only one ground terminal between a pair of signal differential pairs.

[0061] In other embodiments of the cable connector: low-temperature silver brazing can be used to achieve conductivity between the upper conductive strip, the lower conductive strip and the shielding layers of each coaxial cable. At this time, the deposited metal between the strip base of the upper conductive strip and the lower conductive strip is a silver-based low-temperature solder.

[0062] In other embodiments of the cable connector: the upper conductive bar and the lower conductive bar may be connected to the shielding layer of the coaxial cable instead of being welded. For example, spring claws may be formed on the upper conductive bar and the lower conductive bar, and the spring claws are in contact with the shielding layer of the coaxial cable for conduction. Of course, in this case, the upper conductive bar and the lower conductive bar need to be fixed to the module insulator to ensure the conduction effect. The fixing method may be to interference fit the conductive bar in the accommodating groove.

[0063] In other embodiments of the cable connector, only the upper conductive strip can be used to achieve conduction with the shielding layers of each coaxial cable, and the lower conductive strip is no longer used, that is, there is only one conductive strip, and the long positioning protrusion only blocks the upper conductive strip.

[0064] In other embodiments of the cable connector, all the positioning protrusions may be long positioning protrusions, and each protrusion may block the upper conductive strip or the upper conductive strip and the lower conductive strip.

[0065] In other embodiments of the cable connector: the positioning protrusions can also all be short positioning protrusions, and the short positioning protrusions do not block the upper conductive bar or the upper conductive bar and the lower conductive bar. When installing the upper conductive bar or the upper conductive bar and the lower conductive bar, the position of the conductive bar needs to be controlled so that it is not too close to the signal terminal.

[0066] In other embodiments of the cable connector, the positioning protrusion may no longer be formed on the module insulator.

[0067] In other embodiments of the cable connector, the terminal module may not include a socket contact or a pin contact, and in this case, the rounded pins of the terminal are directly plugged into the adapter connector.

[0068] The embodiment of the cable component in the present invention is as follows: the specific structure of the cable component is the same as the straight cable component or the curved cable component in any embodiment of the cable connector described above, and will not be repeated here.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
