Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and in particular to a cable terminal connection assembly, a cable assembly and a cable connector. Background Art

[0002] As the transmission rate requirements of connectors become higher and higher, the requirements for high-frequency performance indicators of connectors have become more stringent. How to reduce the high-frequency crosstalk of connectors is particularly important. Existing high-speed cable connectors usually include a shell, a cable assembly is installed in the shell, the cable assembly includes a cable and a cable terminal connection assembly connected to the cable, the cable terminal connection assembly includes a terminal module and a shielding structure, the terminal module includes differential terminals arranged in pairs, grounding terminals, and a plastic body that forms all terminals as a whole, the differential terminals arranged in pairs constitute a differential signal pair, the grounding terminal is arranged between two adjacent differential signal pairs to isolate and shield the two adjacent differential signal pairs, and the shielding structure is generally arranged on the periphery of each differential signal pair and connected to the grounding terminal. In order to ensure that the crosstalk between adjacent differential signal pairs is as small as possible, the shielding structure generally needs to be wrapped around the differential signal pair as much as possible, that is, the upper, lower, left, and right sides of the differential signal pair need to be shielded and grounded, the left and right sides are generally shielded by the grounding terminal, and the upper and lower sides are generally shielded by the shielding sheet, and the shielding sheet is connected to the grounding terminal.

[0003] However, since the shielding sheet is generally a stamped structure of a thin sheet material strip, the strength is relatively low, especially for long strip wafers. The strength of the thin sheet structure shielding sheet is relatively weak, resulting in poor overall structural stability of the cable terminal connection assembly. It is easy to warp and deform when subjected to external forces, affecting the assembly and shielding effect. In addition, the shielding sheet and the grounding terminal are usually connected by welding or spring-type abutment. When the welding process is used, the high temperature generated may damage other components, and there are certain constraints on the materials of the shielding sheet and the grounding terminal. When the materials are different or the differences are large, it is difficult to ensure the welding effect; and when the spring-type abutment method is used, the spring size requirements are very high, otherwise it is difficult to ensure the contact reliability. Therefore, it is very difficult for the shielding sheet to be in contact with the grounding terminal. Utility Model Content

[0043] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0044] The utility model improves the existing cable connectors to solve the problem that the shielding structure of the existing cable connectors adopts a shielding sheet, which has low strength and is easily warped and deformed when subjected to force, thus affecting the transmission performance of the connector.

[0045] The principle of the cable connector of the utility model is as follows: the shielding structure adopts a shielding installation shell, one side of the shielding installation shell is provided with a receiving groove, which can accommodate the terminal module and the cable, and the shielding installation shell is also provided with a plurality of bosses protruding from the receiving groove, each boss passes through the grounding piece of the terminal module and assembles the shielding installation shell and the terminal module together, each boss is connected with the grounding piece of the terminal module, and at the same time, there is a shielding contact part for contacting the cable shielding layer on the shielding installation shell and / or the grounding piece of the terminal module, so that the shielding installation shell, the grounding piece of the terminal module and the cable shielding layer are all electrically connected, and the cable is accommodated in the receiving groove of the shielding installation shell, thereby forming a multi-directional shielding for each differential pair of the terminal module, and improving the shielding effect. Since the shielding installation shell itself is a shell structure with high strength and basically no deformation, it can ensure that the shielding installation shell and the terminal module will not be deformed during and after the assembly process, so that the overall structural stability of the cable assembly is better, the shape is stable, and it is not easy to warp and deform, thereby ensuring the transmission performance of the connector.

[0046] Embodiment of the cable connector of the utility model:

[0047] The cable connector includes a connector housing and a cable assembly installed in the connector housing. Figure 1-4As shown, the cable assembly includes a cable terminal connection assembly and a cable 3 connected to the cable terminal connection assembly, the cable terminal connection assembly includes a terminal module 2 and a shielding installation shell 1 arranged on one side of the terminal module 2, the terminal module 2 includes a differential pair 201, a grounding piece 202 and a plastic body 203 connecting all the differential pairs 201 and the grounding piece 202 as a whole, adjacent differential pairs 201 are separated by the grounding piece 202, each differential pair 201 is connected to the cable 3, the shielding installation shell 1 has a receiving groove 102 for accommodating the terminal module 2 and the cable 3 on one side facing the terminal module 2, and the shielding installation shell 1 is provided with a plurality of protruding columns 104 protruding from the receiving groove 102, each protruding column 104 passes through the grounding piece 202 of the terminal module 2 and assembles the shielding installation shell 1 and the terminal module 2 together. The shielding installation shell 1 is connected to the grounding piece 202 of the terminal module 2. The grounding piece 202 of the terminal module 2 has a shielding contact portion for contacting the cable shielding layer 301. The shielding installation shell 1 and the terminal module 2 are assembled together through the protrusion 104, and the grounding piece 202 of the shielding installation shell 1 and the terminal module 2 is connected, and the grounding piece 202 of the shielding installation shell 1 and / or the terminal module 2 has a shielding contact portion that contacts the cable shielding layer 301, so that the shielding installation shell 1, the grounding piece 202 of the terminal module 2 and the cable shielding layer 301 are electrically connected, and the cable 3 is accommodated in the accommodating groove 102 of the shielding installation shell 1, thereby forming a multi-directional shielding for each differential pair 201 of the terminal module 2, thereby improving the shielding effect. The shielding installation shell 1 itself is a shell structure with high strength and basically no deformation. Therefore, it can ensure that the shielding installation shell 1 and the terminal module 2 will not be deformed during and after the assembly process, so that the overall structural stability of the cable assembly is better and it is not easy to warp and deform.

[0048] The shielding mounting shell 1 and the terminal module 2 are assembled together by means of a number of bosses 104 on the shielding mounting shell 1. In a preferred embodiment, each boss 104 is riveted to the grounding piece 202 of the terminal module 2. The riveting process can achieve the fixed assembly and conduction of the boss 104 and the grounding piece 202 at the same time, simplify the structure on the basis of ensuring the contact reliability between the boss 104 and the grounding piece 202, and make assembly more convenient; secondly, it can avoid the high temperature generated during welding from damaging other components. Of course, during the assembly process, if the welding effect can be guaranteed and the damage to other components can be reduced, each boss 104 can also be welded to the grounding piece 202 of the terminal module 2, and the fixed assembly and conduction of the boss 104 and the grounding piece 202 can also be achieved at the same time.

[0049] like Figure 1-3As shown in , the depth of the receiving groove 102 is designed according to the height of the plastic body 203 protruding from the differential pair 201 and the grounding piece 202 and the radial dimension of the cable 3, so that the groove edge 103 of the receiving groove 102 fits with the grounding piece 202. In this way, the fitting contact area between the shielding mounting shell 1 and the grounding piece 202 can be increased, the shielding effect can be further improved, and the structural stability can be better. Of course, it can be understood that in actual applications, a small gap between the groove edge of the receiving groove and the grounding piece is also feasible.

[0050] The specific structure of the shielding installation shell 1 is as follows Figure 5-6 As shown, one side of the shielding installation shell 1 has a flat assembly surface 101 for assembling other components of the connector, and the other side of the shielding installation shell 1 has an accommodating groove 102 for accommodating the terminal module 2 and the cable 3. A protrusion 104 is provided on the groove edge 103 of the accommodating groove 102, and the protrusion 104 is used to pass through the grounding piece 202 of the terminal module 2 to assemble the shielding installation shell 1 and the terminal module 2 together. The accommodating groove 102 includes a first groove section 1021 and a second groove section 1022, the second groove section 1022 is connected to the rear end of the first groove section 1021, the first groove section 1021 is used to accommodate the terminal module 2, and the second groove section 1022 is used to accommodate the cable 3 connected to the terminal module 2. The depth of the first groove section 1021 is designed according to the height of the plastic body 203 protruding from the differential pair 201 and the grounding piece 202, so that the groove edge 103 of the first groove section 1021 can fit with the grounding piece 202. The depth of the second slot section 1022 is designed according to the radial dimension of the cable 3 so that the slot edge 103 of the second slot section 1022 can fit with the grounding piece 202. The second slot section 1022 is a contoured slot, and its shape is adapted to the outer shape of the cable 3 connected to the terminal module 2. After the cable 3 is connected to the terminal module 2, the shielding installation shell 1 and the terminal module 2 are assembled together. The shielding installation shell 1 and the terminal module 2 cooperate to clamp the cable 3 in the second slot section 1022. The slot wall of the second slot section 1022 fits with the cable shielding layer 301, which can constrain the cable 3. Of course, the shape of the second slot section can also be different from the outer shape of the cable connected to the terminal module. For example, the second slot section is a rectangular slot. In this case, part of the slot wall of the second slot section fits with the cable shielding layer, and there is a small gap between the remaining part of the slot wall and the cable shielding layer.

[0051] like Figure 4-5As shown in , a side tail of the shielding installation shell 1 facing away from the terminal module 2 is provided with a avoidance groove 105 for avoiding the cable connected to another cable terminal connection assembly, and the avoidance groove 105 and the accommodating groove 102 are arranged in a staggered manner in the arrangement direction of the differential pair 201. When there are more than two cable assemblies, the cables 3 of the same cable assembly are arranged in sequence in the arrangement direction of the differential pair 201, and the cables 3 of different cable assemblies are arranged in sequence perpendicular to the arrangement direction of the differential pair 201. The avoidance groove 105 is provided at the side tail of the shielding installation shell 1 facing away from the terminal module 2 to avoid the cables 3 of the adjacent cable assembly, which is conducive to reducing the installation space of the cables 3 and making the structure more compact. At the same time, the avoidance groove 105 can constrain the cables 3 of the adjacent cable assembly. The avoidance groove 105 and the accommodating groove 102 are arranged in a staggered manner in the arrangement direction of the differential pair 201, so that the cables 3 of each cable assembly can be staggered in the arrangement direction of the differential pair 201. The connector housing is a conductive housing, and rows of protrusions are provided on the connector housing. The number of rows of protrusions is equal to the number of cable assemblies. The rows of protrusions can abut downward on the shielding mounting shell of the cable assembly to electrically connect the connector housing with the shielding mounting shell of each cable assembly, so that the cables of each cable assembly are staggered in the arrangement direction of the differential pair. The rows of protrusions on the connector housing can pass through the cable gaps of adjacent cable assemblies and abut on the shielding mounting shell of the corresponding cable assembly, making the overall structure of the connector more compact. Of course, the avoidance groove can also be not provided on the shielding mounting shell.

[0052] The grounding member 202 of the terminal module 2 has a shielding contact portion for contacting the cable shielding layer 301, and the grounding member 202 is in contact with the cable shielding layer 301 through the shielding contact portion. Figure 7As shown in , the grounding member 202 includes a grounding terminal 2021 located beside each differential pair 201 and an integral connection portion 2022 integrally connecting the tail of each grounding terminal 2021. Adjacent differential pairs 201 are separated by the grounding terminal 2021. The integral connection portion 2022 forms an escape space for the cable 3 connected to the differential pair 201 on one side facing the thickness direction of the terminal module 2. The shielding contact portion is arranged on the integral connection portion 2022. The tails of each grounding terminal 2021 are integrally connected to connect each grounding terminal 2021 to the same ground. The shielding contact portion is arranged on the integral connection portion 2022. The shielding contact portion is in contact with and connected to the cable shielding layer 301, so that all the grounding terminals 2021 and the cable shielding layer 301 of each cable 3 are all connected to the same ground, forming a shield around each differential pair 201, further improving the shielding effect. The one side of the integrated connection portion 2022 facing the thickness direction of the terminal module 2 forms an escape space for the cable 3 connected to the differential pair 201, and the cable 3 is stuck in the receiving groove 102 of the shielding installation shell 1. This arrangement is conducive to reducing the height of the shielding installation shell 1 and thus reducing the overall size of the cable assembly. The grounding member 202 is provided with an installation hole 2023 for the protrusion 104 on the shielding installation shell 1 to pass through.

[0053] like Figure 7 As shown in , the shielding contact part is specifically a contact spring 204 arranged in pairs and in a V-shape. The root of the contact spring 204 is fixedly connected to the integral connection part 2022, and the free end is tilted and cantilevered upward. The roots of the two contact springs 204 of the same pair are close to each other, and the free ends are far away from each other, so that the two contact springs 204 of the same pair are arranged in a V-shape. The contact spring 204 is used to elastically abut against the cable shielding layer 301 and press the cable 3 into the second groove section 1022. On the one hand, it is more conducive to improving the contact reliability between the cable shielding layer 301 and the grounding member 202, and on the other hand, it can make the cable more reliably constrained. Of course, in another embodiment, a convex bump can also be set on the integral connection part of the grounding member as a shielding contact part to contact and conduct with the cable shielding layer; or, the cable shielding layer is directly in contact with the surface of the grounding member, and the surface of the grounding member facing the cable constitutes the shielding contact part.

[0054] In the above embodiment, a shielding contact portion is provided on the grounding member 202 of the terminal module 2, and the shielding contact portion is in contact with the cable shielding layer 301, so that the shielding installation shell 1, the grounding member 202 of the terminal module 2 and the cable shielding layer 301 of each cable 3 are all connected to the same ground. Of course, in other embodiments, a shielding contact portion can also be provided on the shielding installation shell, for example, a spring piece or a convex bump is provided on the slot wall of the receiving slot of the shielding installation shell, and the spring piece or the convex bump is in contact with the cable shielding layer, so that the shielding installation shell, the grounding member of the terminal module and the cable shielding layer of each cable are all connected to the same ground; or shielding contact portions are provided on both the shielding installation shell and the grounding member of the terminal module, a spring piece or a convex bump is provided on the slot wall of the receiving slot of the shielding installation shell as a shielding contact portion, and a contact spring piece is provided on the grounding member of the terminal module as a shielding contact portion, and the shielding contact portion of the shielding installation shell and the shielding contact portion of the grounding member are both in contact with the cable shielding layer, so that the shielding installation shell, the grounding member of the terminal module and the cable shielding layer of each cable are all connected to the same ground.
