[0035] Example 1

[0036] This embodiment provides a connector with a waterproof structure, as shown in the attached figure. Figures 1-3 As shown, it includes:

[0037] The main body includes a connecting pipe 11, which is a part of the main body. The main body also includes a connector end 12, which mates with one end of the connecting pipe 11. The connector end 12 is used to form a plug-in connection with other electrical components, creating an electrical connection. This is prior art and will not be described in detail in this embodiment. It should also be noted that a sealing structure is provided between the connector end 12 and one end of the connecting pipe 11, for example, through a sealing ring or other sealing method.

[0038] The sealing element 13 is provided with a through hole 131 and a glue filling cavity 132, and the through hole 131 is connected to the glue filling cavity 132.

[0039] Tail clip assembly 15, one end of which is connected to connecting pipe 11, and the other end of tail clip assembly 15 is connected to seal 13.

[0040] In the first state, after the insulation layer 141 is removed from the front end of the cable 14, the exposed conductor 142 is located at the front end of the cable 14. The exposed conductor 142 passes through the through hole 131 and the potting cavity 132, and the cable 14 extends to the through hole 131. At this time, the sidewall of the insulation layer 141 abuts against the inner wall of the through hole 131. The potting cavity 132 is filled with glue, and the potting cavity 132 forms a sealed filling effect through the glue filling method. The glue used here can be epoxy resin or silicone resin, etc., and those skilled in the art can adjust the relevant materials according to actual needs. After the glue filling is completed, the exposed position of the cable 14 is sealed, and liquids and rainwater cannot penetrate into the interior of the cable 14, forming an insulating and waterproof effect. At the same time, the cable 14 and the sealing element 13 form a modular structure, which makes it easier to install and fix.

[0041] In the second state, the exposed wire 142 passes through the connecting pipe 11 and connects to the connector end 12. Here, the wire 142 and the connector end 12 are riveted together to improve the electrical connection between them. The tail clip assembly 15 connects the connecting pipe 11 and the seal 13, and the tail clip assembly 15 forms a fixation between the connecting pipe 11 and the seal 13.

[0042] By applying adhesive, the exposed wires 142, cables 14, and seals 13 are modularized, forming a seal at the exposed areas to prevent rainwater or liquid from entering the inside of the cable 14, creating a waterproof seal and preventing short circuits inside the cable 14, thus improving the overall performance.

[0043] Specifically, as shown in the attached document Figures 2-3 As shown, one of the tail clip assembly 15 and the seal 13 is provided with a fixing groove 16, and the other of the tail clip assembly 15 and the seal 13 is provided with a protrusion 17 that mates with the fixing groove 16. The engagement of the fixing groove 16 and the protrusion 17 improves the connection and fixation effect between the tail clip assembly 15 and the seal 13, preventing the seal 13 from falling off. When the tail clip assembly 15 is provided with the fixing groove 16, the seal 13 is provided with the protrusion 17; conversely, when the tail clip assembly 15 is provided with the protrusion 17, the seal 13 is provided with the fixing groove 16. In addition, other anti-fall-off structures can be used between the tail clip assembly 15 and the seal 13.

[0044] Specifically, as shown in the attached document Figures 2-3 As shown, the tail clip assembly 15 has a fixing cavity 151, and the sealing element 13 is entirely located within the fixing cavity 151. The fixing cavity 151 has a fixing groove 16 on its side wall, and the sealing element 13 has a protrusion 17. The fixing groove 16 and the protrusion 17 cooperate to prevent the sealing element 13 from falling off. The connecting pipe 11 extends partially into the fixing cavity 151 to achieve connection and fixation between the connecting pipe 11 and the inner wall of the fixing cavity 151.

[0045] Specifically, as shown in the attached document Figures 2-3 As shown, the inner wall of the through hole 131 is provided with a raised rib 133. This improves the sealing effect between the inner wall of the through hole 131 and the insulation layer 141 of the cable 14. The number of raised ribs 133 can be adjusted according to actual needs; there can be one, two, or even more.

[0046] Specifically, through-hole 131 is filled with adhesive. Through-hole 131 is also filled with adhesive to further improve the overall sealing level.

[0047] Specifically, as shown in the attached document Figures 1-3As shown, the tail clip assembly 15 includes a first component 152 and a second component 153, which are joined together to form a connection between the connecting pipe 11 and the sealing element 13. The first component 152 and the second component 153 cooperate to form a clamping and fixing structure, making installation more convenient and fixing more stable.

[0048] Specifically, as shown in the attached document Figures 1-3 As shown, the first component 152 has a first fastening hole 1521, and the second component 153 has a second fastening hole 1531. Bolts pass through the first fastening hole 1521 and engage with the second fastening hole 1531. Fastening with bolts improves the connection strength between the first component 152 and the second component 153. There can be two first fastening holes 1521, symmetrically arranged, and two second fastening holes 1531, secured by two bolts. Alternatively, the first component 152 and the second component 153 can be hinged at one end, with the other end connected and secured by bolts passing through the first fastening hole 1521 and the second fastening hole 1531.

[0049] Specifically, as shown in the attached document Figures 1-3 As shown, both the first component 152 and the second component 153 are provided with a first fixing hole 154, and the connecting pipe 11 is provided with a second fixing hole 111 that mates with the first fixing hole 154. The connection and fixation between the tail clip assembly 15 and the connecting pipe 11 are achieved through the cooperation of the first fixing hole 154 and the second fixing hole 111.

[0050] Specifically, the seal 13 is made of rubber. After the first component 152 and the second component 153 are fixed, the seal 13 and the inner wall of the fixing cavity 151 form an interference fit, improving the sealing level. At the same time, the insulating layer 141 and the inner wall of the through hole 131 also form an interference fit, improving the sealing level.

[0051] Specifically, the connecting pipe 11 can be a bent pipe or a straight pipe. Those skilled in the art can adjust the shape of the connecting pipe 11 according to actual needs.

[0052] Specifically, connector 12 can be either male or female. When connector 12 is male, other electrical components are female; conversely, when connector 12 is female, other electrical components are male.

[0053] Specifically, to improve the overall sealing effect, a waterproof seal can be formed between the wire 142 and the connector end 12 using an adhesive-filled structure. The connection between the connecting tube 11 and the tail clip assembly 15 can be sealed using a sealing ring or other sealing structure.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
