[0001] This application relates to the field of cable connector technology, specifically to a wire end connector and connector module. Background Technology

[0002] With the continuous increase in bandwidth and network speed requirements, traditional PCB interconnects are increasingly unable to meet performance and cost demands. Traditional printed circuit board (PCB) interconnects are gradually evolving into high-speed cable connections. Cable connectors are mainly used for signal transmission between various digital program-controlled exchanges, optoelectronic transmission equipment, and patch panels in transmission equipment, for transmitting data, audio, video, and other communication devices, and are now rapidly expanding into various fields.

[0003] In the prior art, the wire connector includes a base, a top cover, a PCB board, and a mold. The base and the top cover are usually assembled by attaching the top cover to the base. However, during the actual assembly process, operational errors may cause inaccurate assembly positions, resulting in an unstable structure. Utility Model Content

[0004] This application mainly provides a wire-end connector and connector module, which can avoid the situation where the top cover and base are not assembled in an accurate position, resulting in an unstable structure.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a wire end connector, the wire end connector comprising: a base having an accommodating space; a PCB assembly disposed within the accommodating space; and a top cover, one of the base and the top cover having a guide protrusion, and the other of the base and the top cover having a guide groove, the guide protrusion being inserted into the guide groove and sliding along the guide groove, so that the top cover slides relative to the base in the extending direction of the guide groove until it covers the base.

[0006] In one specific embodiment, the base is further provided with a first sealing part, and the upper cover is provided with a second sealing part, the first sealing part and the second sealing part being configured to cooperate with each other.

[0007] In one embodiment, the top cover includes a stop surface disposed on one side facing the extension direction of the guide groove, the stop surface being used to stop the PCB assembly in the sliding direction in which the top cover slides relative to the base.

[0008] In one specific embodiment, the PCB assembly includes a PCB board and a mold, the PCB board being disposed within the accommodating space, and the mold being injection molded within the accommodating space.

[0009] In one specific embodiment, the PCB board is provided with pads and a gold finger row, wherein multiple gold fingers in the gold finger row are arranged at equal intervals with the pads.

[0010] In one specific embodiment, the base is provided with a first fastening part, and the upper cover is provided with a second fastening part, wherein the first fastening part and the second fastening part are fastened together.

[0011] In one specific embodiment, there are multiple first fastening parts, which are respectively disposed on different sides of the base; there are also multiple second fastening parts, which are respectively disposed on different sides of the top cover.

[0012] In one specific embodiment, the wire connector further includes a resilient latch, and the base has a mounting groove in which the resilient latch is installed.

[0013] In one specific embodiment, the wire end connector further includes a pull strap, the elastic buckle has a first pull strap mounting hole, the upper cover has a second pull strap mounting hole, and the pull strap passes through the first pull strap mounting hole and the second pull strap mounting hole in sequence.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a connector module, which includes a board-end connector and the wire-end connector, wherein the wire-end connector and the board-end connector are detachably connected.

[0015] The beneficial effects of this application are as follows: Unlike the prior art, the wire-end connector for robots provided in this application includes: a base forming an accommodating space; a PCB assembly disposed within the accommodating space; and a top cover, one of the base and the top cover having a guide protrusion, and the other of the base and the top cover having a guide groove. The guide protrusion is used to insert into the guide groove and slide along the guide groove, so that the top cover slides relative to the base in the extension direction of the guide groove until it covers the base, thereby clamping the PCB assembly between the base and the top cover. With this arrangement, during the assembly of the top cover and the base, on the one hand, the guiding effect of the guide groove can improve the ease of assembly; on the other hand, the cooperation between the guide protrusion and the guide groove can position the top cover and the base during assembly.

[0026] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a three-dimensional assembly structure diagram of the embodiment of the wire connector 10 provided in this application. Figure 2 yes Figure 1 A three-dimensional exploded view of the center-end connector 10. In this embodiment, the center-end connector 10 includes a base 11, a PCB assembly 12, and a top cover 13.

[0027] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 2 A three-dimensional structural diagram of the central base 11. Figure 4 yes Figure 2 A three-dimensional structural diagram of the upper cover 13 shows that the base 11 forms an accommodating space 101, and the PCB assembly 12 is disposed within the accommodating space 101.

[0028] Furthermore, one of the base 11 and the top cover 13 is provided with a guide protrusion 11a, and the other of the base 11 and the top cover 13 is provided with a guide groove 13a. The guide protrusion 11a is used to insert into the guide groove 13a and slide along the guide groove 13a, so that the top cover 13 slides relative to the base 11 in the extension direction of the guide groove 13a until it covers the base 11, thereby allowing the PCB assembly 12 to be sandwiched between the base 11 and the top cover 13. With this arrangement, during the assembly process of the top cover 13 and the base 11, on the one hand, the guiding effect of the guide groove 13a can improve the ease of assembly, and on the other hand, the cooperation between the guide protrusion 11a and the guide groove 13a can position the assembly of the top cover 13 and the base 11. The positioning method is simple and avoids the situation where the assembly position of the two is inaccurate, resulting in an unstable structure.

[0029] Please refer to the following: Figure 2 and Figure 5 , Figure 5 yes Figure 2 The front view of the PCB board is shown in the schematic diagram. The PCB assembly 12 includes a PCB board (Printed Circuit Board) 121 and a mold 122. The PCB board 121 is disposed in the accommodating space 101, and the mold 122 is injection molded in the accommodating space 101.

[0030] Specifically, in practical applications, the assembly process of the wire connector 10 is as follows: First, the PCB board 121 is placed in the accommodating space 101. Then, the upper cover 13 is slid onto the base 11 as described above to limit the PCB board 121. Finally, injection molding is performed into the accommodating space 101 through the injection hole to form the mold body 122, thereby encapsulating the PCB board 121 in the accommodating space 101. In this embodiment, the mold body 122 includes an inner mold 1221 and an outer mold 1222.

[0031] The PCB board 121 is provided with pads 1211 and gold finger arrays 1212. Multiple gold fingers in the gold finger array 1212 are equally spaced from the pads 1211, that is, the distance between each gold finger and the pad 1211 is the same. This single pad setting method simplifies the complexity of PCB board routing and improves the SI performance of the PCB board 121.

[0032] Further reading Figure 3 and Figure 4 The base 11 is also provided with a first sealing part 11b, and the upper cover 13 is provided with a second sealing part 13b. The first sealing part 11b and the second sealing part 13b are configured to cooperate so that during the injection molding process of forming the mold body 122, the first sealing part 11b and the second sealing part 13b cooperate to seal tightly and avoid glue overflow.

[0033] Optionally, the upper cover 13 includes a stop surface 13c provided on one side facing the extension direction of the guide groove 13a. The stop surface 13c is used to stop the PCB assembly 12 in the sliding direction of the upper cover 13 relative to the base 11. That is, during the assembly of the upper cover 13 and the base 11, when the stop surface 13c stops the PCB assembly 12, it indicates that the upper cover 13 is installed in place.

[0034] Furthermore, in this embodiment, the base 11 is provided with a first fastening part 11c, and the upper cover 13 is provided with a second fastening part 13d. The first fastening part 11c and the second fastening part 13d are fastened together. That is, during the assembly of the upper cover 13 and the base 11, after the upper cover 13 is placed on the base 11, the first fastening part 11c and the second fastening part 13d are fastened together to prevent the upper cover 13 from falling off the base 11 and to improve the structural stability.

[0035] Optionally, there are multiple first fastening parts 11c, which are respectively disposed on different sides of the base 11, and multiple second fastening parts 13d, which are respectively disposed on different sides of the top cover 13.

[0036] Further reading Figure 1 and Figure 2 In this embodiment, the wire connector 10 also includes an elastic latch 14. The base 11 has a mounting groove 102, and the elastic latch 14 is installed in the mounting groove 102 so that the wire connector 10 and the board connector can be detachably snapped together.

[0037] The elastic buckle 14 can be a press-type elastic buckle or a pull-type elastic buckle. In this embodiment, the elastic buckle 14 is a pull-type elastic buckle. That is, in this embodiment, the wire connector 10 also includes a pull strap 15. The elastic buckle 14 has a first pull strap mounting hole 103, and the upper cover 13 has a second pull strap mounting hole 104. The pull strap 15 passes through the first pull strap mounting hole 103 and the second pull strap mounting hole 104 in sequence, so that when the pull strap 15 is pulled, the elastic buckle 14 can undergo elastic deformation, thereby detaching the wire connector 10 from the board connector.

[0038] Please see Figure 6 , Figure 6 This is a three-dimensional structural diagram of an embodiment of the connector module 20 provided in this application. The connector module 20 in this embodiment includes a board-end connector 21 and a wire-end connector 10 as described in the above embodiments.

[0039] The wire connector 10 and the board connector 21 are detachably connected. In this embodiment, the detachable connection between the two is achieved by the elastic latch 14 mentioned above.

[0040] The beneficial effects of this application are as follows: Unlike the prior art, the wire-end connector for robots provided in this application includes: a base forming an accommodating space; a PCB assembly disposed within the accommodating space; and a top cover, one of the base and the top cover having a guide protrusion, and the other of the base and the top cover having a guide groove. The guide protrusion is used to insert into the guide groove and slide along the guide groove, so that the top cover slides relative to the base in the extension direction of the guide groove until it covers the base, thereby clamping the PCB assembly between the base and the top cover. With this arrangement, during the assembly of the top cover and the base, on the one hand, the guiding effect of the guide groove can improve the ease of assembly; on the other hand, the cooperation between the guide protrusion and the guide groove can position the top cover and the base during assembly. The positioning method is simple and avoids inaccurate assembly positions, which could lead to an unstable structure.

[0041] The above description is only a partial embodiment of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the scope of patent protection of this application.
