Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a cable connector for stable cable terminal connection. Background Technology

[0002] Connectors are a common component in electrical engineering. Their function is to connect circuits on different devices or different modules in a circuit, so that current or signals can flow or be transmitted, and the circuit can perform its intended function.

[0003] One type of connector is the cable connector, which is mainly used to connect conductive terminals to cables. One end of the cable is connected to the conductive terminal inside the housing, and the other end of the cable is led out from the housing. Since they are mostly used for the transmission of large currents, the diameter of the cable is relatively large. Not only is it necessary to support and fix the cable connection part of the conductive terminal, but it is also necessary to limit the relative position of the cable to improve the connection stability of the cable. Utility Model Content

[0004] The purpose of this invention is to provide a cable connector that provides stable cable terminal connections.

[0005] To achieve the purpose of this utility model, a cable connector for stable cable terminal connection is provided, including a connecting shell, a terminal shell, conductive terminals, and a tail cap. The connecting shell has a first mounting hole along the insertion direction, and the inner wall of the first mounting hole has a bearing step. The first mounting hole is divided into an outer hole section and an inner hole section based on the bearing step. The outer wall of the terminal shell has a positioning block. The terminal shell is installed in the first mounting hole, and the positioning block is fixedly installed in the outer hole section. The terminal shell has a second mounting hole along the insertion direction, and the conductive terminal is installed in the second mounting hole. The outer end of the conductive terminal has an external connection part, and the inner end of the conductive terminal has an internal connection part, which has a cable hole. The tail cap includes an end wall, an outer... The inner and outer ring walls extend in the insertion direction. The inner ring wall is located inside the outer ring wall. The end wall is connected between the axial end of the outer ring wall and the axial end of the inner ring wall. A through hole is provided in the inner ring wall along the insertion direction. A positioning ring is formed between the outer ring wall, the end wall, and the inner ring wall. A first locking part is provided on the outer wall of the inner end of the terminal housing. The tail cap is connected to the inner end of the terminal housing. The inner end of the terminal housing is located inside the positioning ring. A second locking part is provided on the outer ring wall. The outer ring wall is located outside the terminal housing. The first locking part and the second locking part engage. The inner ring wall is located inside the terminal housing. The inner ring wall is adjacent to the inner end of the conductive terminal and forms a limit on the conductive terminal along the insertion direction. The through hole communicates with the cable hole.

[0006] A further alternative is to position the tail cap inside the first mounting hole.

[0007] A further proposed solution is to have multiple first deformation grooves on the outer ring wall, with the multiple first deformation grooves distributed circumferentially.

[0008] A further proposed solution is to have multiple second locking parts on the outer ring wall, with the multiple second locking parts distributed circumferentially, and multiple first deformation grooves and multiple second locking parts arranged alternately circumferentially.

[0009] A further proposed solution is to have multiple second deformation grooves on the inner ring wall, with these grooves distributed circumferentially.

[0010] A further proposed solution is to make the height of the outer ring wall greater than the height of the inner ring wall in the insertion direction.

[0011] A further proposed solution is that the first card section is arranged as a card block, and the first card section is arranged as a card slot, with the card slot engaging with the card block.

[0012] A further alternative is that the cable connector includes a pressure ring and a collar, with the collar fitted onto the outer wall of the terminal housing, a positioning block disposed on the collar, and the pressure ring interference fit onto the outer bore section. The pressure ring is adjacent to the collar and provides a limit to the collar along the insertion direction.

[0013] A further alternative is that the cable connector includes a cable, the end of which is located inside and connected to the cable hole, and the cable passes through the through hole and exits from the connector housing.

[0014] A further alternative is that the cable connector includes a waterproof plug located at the end of the inner bore section through which the cable passes.

[0015] The beneficial effects of this utility model are as follows: when the cable is connected to the conductive terminal, the end of the cable is located inside the cable hole and connected to the cable hole, and is fixed in place by the closing of the tail cap. That is, the outer ring wall is used to connect and fix the cable to the terminal housing, and the inner ring wall is used to limit the conductive terminal along the insertion direction, thereby allowing the conductive terminal to be stably assembled in the terminal housing. In addition, the cable passes through the through hole and is led out from the connecting housing, and the arrangement of the waterproof plug improves the overall protection of the connector and the connection stability of the cable. Furthermore, through the arrangement of the first deformation groove, the second deformation groove, and multiple locking parts, and the use of the relatively long outer ring wall, the connection redundancy and stability of the tail cap are improved. Moreover, the installation and positioning of the terminal housing by the pressure ring and the collar ensures that the terminal housing can be stably assembled. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0024] Reference Figures 1 to 7 The cable connector 1 includes a connecting housing 11, a terminal housing 12, a conductive terminal 15, a pressure ring 17, a waterproof plug 18, a collar 14, a cable 16, and a tail cap 13. The connecting housing 11 is provided with a first mounting hole 111 along the insertion direction Z. The first mounting hole 111 extends through the insertion direction Z. The inner wall of the first mounting hole 111 is provided with a bearing step 114. The first mounting hole 111 is divided into an outer hole section 112 and an inner hole section 113 based on the bearing step 114.

[0025] A collar 14 is fitted onto the outer wall of the terminal housing 12. Multiple positioning blocks 141 are provided on the outer wall of the collar 14, evenly distributed circumferentially and arranged in a rectangular pattern. The terminal housing 12 is installed within the first mounting hole 111, and the positioning blocks 141 are fixedly installed within the outer hole section 112. A pressure ring 17 is interference-fitted onto the outer hole section 112 and located outside the multiple positioning blocks 141 based on the insertion direction Z. The pressure ring 17 is adjacent to the collar 14 and provides a limit to the collar 14 along the insertion direction Z. Alternatively, in addition to this embodiment, positioning blocks can be directly provided on the outer wall of the terminal housing, and installation and fixation within the outer hole section can also be achieved using these positioning blocks.

[0026] The terminal housing 12 has a second mounting hole 121 extending through the insertion direction Z. A conductive terminal 15 is installed within the second mounting hole 121. The outer end of the conductive terminal 15 has an external connecting portion 151, which connects to the conductive terminal of the other cable connector 2 when the cable connector 1 is connected to it. The inner end of the conductive terminal 15 has an internal connecting portion 152, which contains a cable hole 153. The cable hole 153 is a blind hole extending along the insertion direction Z. The end of the cable 16 is located within and connected to the cable hole 153. It can be fixedly connected to the cable hole 153 by interference fit.

[0027] The tail cap 13 includes an end wall 133, an outer ring wall 131, and an inner ring wall 132. Both the outer ring wall 131 and the inner ring wall 132 extend in the insertion direction Z. The inner ring wall 132 is located inside the outer ring wall 131. The end wall 133 is connected between the axial end of the outer ring wall 131 and the axial end of the inner ring wall 132. A through hole 138 is provided in the inner ring wall 132 along the insertion direction Z. A positioning ring 134 is formed between the outer ring wall 131, the end wall 133, and the inner ring wall 132.

[0028] The outer wall of the inner end of the terminal housing 12 is provided with a plurality of first locking parts 122, which are evenly distributed circumferentially and arranged in a locking block manner. The tail cover 13 is connected to the inner end of the terminal housing 12 and is located in the first mounting hole 111. The inner end of the terminal housing 12 is located in the positioning ring 134. The outer ring wall 131 is provided with a plurality of second locking parts 135, which are evenly distributed circumferentially and arranged in a locking slot manner. The outer ring wall 131 is located on the outer side of the terminal housing 12. The first locking parts 122 and the second locking parts 135 engage, that is, the locking slot engages with the locking block. The inner ring wall 132 is located on the inner side of the terminal housing 12.

[0029] The outer annular wall 131 is provided with a plurality of first deformation grooves 136, which are distributed circumferentially. The plurality of first deformation grooves 136 and a plurality of second locking portions 135 are arranged alternately circumferentially. The inner annular wall 132 is provided with a plurality of second deformation grooves 137, which are distributed circumferentially. In the insertion direction Z, the height of the outer annular wall 131 is greater than the height of the inner annular wall 132.

[0030] Since the through hole 138 communicates with the cable hole 153, the cable 16 passes through the through hole 138 and is led out from the connecting housing 11. The waterproof plug 18 is provided at the end of the inner hole section 113. The cable 16 passes through the waterproof plug. Furthermore, the inner ring wall 132 is located outside the conductive terminal 15 based on the insertion direction Z. The inner ring wall 132 is adjacent to the inner end of the conductive terminal 15 and forms a limit on the conductive terminal 15 along the insertion direction Z.

[0031] As can be seen from the above, when the cable is connected to the conductive terminal, the end of the cable is located inside the cable hole and connected to the cable hole. It is also fixed by the closing of the end cap. That is, the outer ring wall is used to connect and fix the cable to the terminal housing, and the inner ring wall is used to limit the conductive terminal along the insertion direction. This allows the conductive terminal to be stably assembled in the terminal housing. In addition, the cable passes through the through hole and is led out from the connecting housing. The arrangement of the waterproof plug further improves the overall protection of the connector and the connection stability of the cable.
