[0018] Figure 4 This is a schematic diagram of the second embodiment of the present invention. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] First embodiment: refer to Figures 1 to 4 As shown, a water-proof connector includes a lower connector 1 and a terminal block 2 embedded in the lower connector 1. The terminal block 2 is provided with a plurality of partition cavities 201 for assembling terminal components. The top of the lower connector 1 is provided with a plurality of insertion holes 101 corresponding to the partition cavities 201. An upper waterproof pad 3 and a lower waterproof pad 4 are provided on the lower connector 1 between the insertion holes 101 and the partition cavities 201. Both the upper waterproof pad 3 and the lower waterproof pad 4 are provided with waterproof holes 5 that correspond to the positions of the insertion holes 101 and can be elastically opened and closed.

[0021] This connector features a two-layer waterproof pad structure, which can pass an overflow test and further enhance its waterproof and dustproof performance. Even if a small amount of water seeps into the upper waterproof pad 3, it will be blocked by the lower waterproof pad 4, preventing the water from directly contacting the terminal components. The water will evaporate and disappear, thus significantly reducing or completely preventing water from seeping into the partition cavity 201. During use, users can prevent water from entering the live terminal components and causing short circuits or interference.

[0022] A spacer X is provided between the upper waterproof pad 3 and the lower waterproof pad 4, and the upper waterproof pad 3 and the lower waterproof pad 4 are arranged vertically at intervals through the spacer X; the spacer X is used to maintain the distance between the upper waterproof pad 3 and the lower waterproof pad 4, and the spacer X is a rigid material that provides support for the upper waterproof pad 3 and the lower waterproof pad 4.

[0023] Specifically, the lower connector 1 includes a plug housing 6 and a top cover 7. The top cover 7 is connected to the top wall of the plug housing 6, and several sockets 101 are opened on the top cover 7. The upper waterproof pad 3 is disposed between the top cover 7 and the top wall of the plug housing 6. The upper waterproof pad 3 is assembled using the top cover 7, which facilitates the installation, disassembly and replacement of the upper waterproof pad 3.

[0024] The top wall of the plug housing 6 forms a spacer member X, and the top wall of the plug housing 6 is provided with a plurality of through holes 102 corresponding to the position of the socket 101. The lower waterproof pad 4 is disposed between the top wall of the plug housing 6 and the terminal block 2. The lower waterproof pad 4 is pressed into the plug housing 6 so that the lower waterproof pad 4 can be evenly stressed and can prevent the lower waterproof pad 4 from deforming.

[0025] Both the upper waterproof pad 3 and the lower waterproof pad 4 include a silicone pad 31. Several silicone bosses 32 extend from the silicone pad 31 and protrude into the insertion hole 101 or through hole 102. The silicone bosses 32 of the upper waterproof pad 3 are flush with the top surface of the top cover 7, and each silicone boss 32 forms a waterproof hole 5 through an H-shaped or cross-shaped cut. The shape of the silicone boss 32 matches the socket 101 or the through hole 102, filling the gap between them and preventing water from accumulating in the socket 101 or the through hole 102. When the pin of the upper connector is inserted, it can push open the waterproof holes 5 of the upper and lower layers. When the upper connector is decoupled, the diaphragm of the waterproof hole 5 resets and seals the upper and lower waterproof holes 5 again.

[0026] The top cover 7 has a ring cover edge 71 extending around its periphery, and the top wall of the plug housing 6 has a ring step 61 around its periphery. The top cover 7 is positioned and connected to the plug housing 6 by the ring cover edge 71 nesting on the ring step 61. This allows the top cover 7 to be directly positioned during installation, improving assembly efficiency. Moreover, the edges form a tortuous joint, which serves as a waterproofing mechanism, preventing water from seeping into the lower waterproof pad 4 through the joint between the top cover 7 and the plug housing 6.

[0027] The top cover 7 is provided with a first connecting part, and the plug housing 6 is provided with a second connecting part corresponding to the first connecting part. Through the cooperation of the first connecting part and the second connecting part, the top cover 7 can be detachably or non-detachably connected to the top wall of the plug housing 6.

[0028] Specifically, at least one pair of opposing inner sidewalls of the ring cover edge 71 are provided with a plurality of top cover snap blocks 72, which together form a first connecting part. The inner sidewall of the ring step 61 is provided with a plurality of upper snap interfaces 62 corresponding to the top cover snap blocks 72, which together form a second connecting part. The top cover 7 is fastened to the top wall of the plug housing 6 by the top cover snap blocks 72 and the upper snap interfaces 62, and at the same time, the upper waterproof gasket 3 is pressed tightly. This connection method is simple, quick, firm and stable, and can eliminate the need for fasteners, save costs and improve assembly efficiency.

[0029] The bottom of the plug housing 6 has at least one pair of sides with several buckle interfaces 63. The terminal block 2 extends with several terminal block buckle blocks 73 corresponding to the buckle interfaces 63. The terminal block 2 is fastened and fixed inside the plug housing 6 by the terminal block buckle blocks 73 and the buckle interfaces 63, and at the same time, the lower waterproof pad 4 is pressed. This connection method can fix the position of the terminal block 2, and directly press the lower waterproof gasket 4 after assembly. The connection is simple, quick, firm and stable, which can eliminate the need for fasteners, save costs and improve assembly efficiency.
