[0037] See also Figure 1-Figure 9, which is a schematic structural diagram of a waterproof cable connector provided in one embodiment of the utility model, the waterproof cable connector comprises a plug-in assembly, a docking assembly arranged at the periphery of the plug-in assembly, a transfer assembly rotatably connected to the periphery of the docking assembly, and a fixing assembly rotatably connected to the periphery of the transfer assembly, wherein:

[0038] In order to achieve the function of connecting the wire core 610 inside the cable, the connector assembly includes a first connector 110 and a second connector 120 arranged opposite to the first connector 110, and the first connector 110 and the second connector 120 together enclose a plug-in area for connecting the wire core 610. The first connector 110 is provided with a first threaded hole 111 and a first terminal hole 112, and the second connector 120 is provided with a second threaded hole 121 and a second terminal hole 122. The first terminal hole 112 is provided with a female terminal 113 for accommodating the wire core 610, and the second terminal hole 122 is provided with a male terminal 123 for accommodating the wire core 610. The female terminal 113 is provided with a female end hole 114 aligned with the first threaded hole 111, and the male terminal 123 is provided with a male end hole 124 aligned with the second threaded hole 121.

[0039] During installation, the female terminal 113 is first inserted into the first terminal hole 112, and can be connected to the first connector 110 by gluing, and the first threaded hole 111 is aligned with the female end hole 114, and the fastener 700 is screwed to the first threaded hole 111 and inserted into the female end hole 114, and the wire core 610 placed therein along the length direction of the female terminal 113 is fixed inside the female terminal 113. Similarly, the male terminal 123 is inserted into the second terminal hole 122, and can be connected to the second connector 120 by gluing, and the second threaded hole 121 is aligned with the male end hole 124, and the fastener 700 is screwed to the second threaded hole 121 and inserted into the male end hole 124, and the wire core 610 placed therein along the length direction of the male terminal 123 is fixed inside the male terminal 123. Since the female terminal 113 is provided with a connecting step 115 on its outer periphery and the male terminal 123 is provided with a male step 125 on its outer periphery, the male terminal 123 can be inserted into the female terminal 113 to complete the connection of the wire cores 610 between the two cables and perform data transmission; and the connecting step 115 is axially positioned with the first docking member 210 through an elastic member 800.

[0040] In order to connect the first connector 110 and the second connector 120 and prevent them from loosening, a docking assembly and a transfer assembly are provided on the periphery of the first connector 110 and the second connector 120. The docking assembly includes a first docking member 210 provided on the periphery of the first connector 110 and a second docking member 220 provided on the periphery of the second connector 120. The end surface of the first docking member 210 is provided with a recessed portion, and the end surface of the second docking member 220 is provided with a protruding portion. When the second docking member 220 is connected to the first docking member 210, the protruding portion is embedded in the recessed portion. In this embodiment, the connector assembly, the docking assembly, the docking assembly and the fixing assembly are all cylindrical. Therefore, when the protruding portion is embedded in the recessed portion, the first docking member 210 and the second docking member 220 are rotated at a preset angle, and then the first docking member 210 and the second docking member 220 are fixed together.

[0041] In order to achieve good waterproof performance, a first seal 410 is provided on the inner periphery of the recessed portion. When the protruding portion is embedded in the recessed portion, due to the extrusion of the protruding portion, the first seal 410 is respectively interference fit with the protruding portion and the recessed portion, thereby achieving good waterproof performance.

[0042] In order to further reinforce the first docking member 210 and the second docking member 220, and to connect with the adapter assembly, a docking threaded portion is provided on the outer periphery of the first docking member 210 and the second docking member 220, so the adapter assembly is rotatably connected to the outer periphery of the first docking member 210 and the second docking member 220. The adapter assembly includes a first adapter 310 threadedly connected to the first docking member 210, and a second adapter 320 threadedly connected to the second docking member 220. A second sealing member 420 is also provided on the outer periphery of the first docking member 210 and the second docking member 220. After the first adapter 310 and the first docking member 210, the second adapter 320 and the second docking member 220 are threadedly connected, the second sealing member 420 is squeezed, so that the second sealing member 420 is interference-fitted with the first adapter 310 and the first docking member 210, the second adapter 320 and the second docking member 220 on both sides, thereby ensuring the waterproofness between the adapter assembly and the docking assembly.

[0043] In order to further enhance the waterproof performance, a sealing sleeve 430 is provided inside the first adapter 310 and the second adapter 320. The outer diameter of the sealing sleeve 430 increases successively, so that it is isosceles trapezoidal and is sleeved on the outer periphery of the cable 600. However, due to the limited internal space of the first adapter 310 and the second adapter 320, the sealing sleeve 430 is squeezed so that it is tightly pressed on the outer periphery of the cable 600. In order to reinforce the first adapter 310 and the second adapter 320, a transfer thread portion is provided on the outer periphery thereof, so as to rotatably connect the first fixing member 510 and the second fixing member 520 on the outer periphery of the first adapter 310 and the second adapter 320 respectively. The inner periphery of the first fixing member 510 and the second fixing member 520 is provided with an internal thread, and the first fixing member 510 and the second fixing member 520 seal the sealing sleeve 430 in the first adapter 310 and the second adapter 320, thereby achieving a better waterproof effect.

[0044] In summary, according to a waterproof cable connector proposed by the utility model, a plug-in area for cable connection is synthesized by using a first connector and a second connector, and a docking component and an adapter component are sleeved on the outside of the first connector and the second connector to connect the first connector and the second connector, and a seal and a sealing sleeve are respectively provided between the docking component and the plug-in component, and between the docking component and the adapter component to ensure the dryness and waterproofness of the cable connector. Specifically, the first connector and the second connector are arranged relative to each other to connect two cables respectively, and the docking component is sleeved on the outer periphery of the first connector and the second connector to fix the first connector and the second connector, and the docking component is provided with seals inside and outside to ensure the dryness between the first connector and the second connector. The outer periphery of the docking component is rotatably connected with the adapter component, and while reinforcing the docking component, a sealing sleeve is also provided inside, which is sleeved on the outer periphery of the cable, and is rotatably connected to the outer periphery of the adapter component through the fixing component to press the sealing sleeve on the outer periphery of the cable to achieve the purpose of interference fit, so that the wire core has good waterproof performance from both axial and radial directions.
