[0037] In one embodiment of the connector of the present invention, please refer to Figures 1 to 10. The connector includes a plug 100 and a socket 200. The plug 100 includes a plug body and a first connecting conductor 110. A sleeve 120 is provided at one end of the plug body. The first connecting conductor 110 is arranged in the plug body. An end of the first connecting conductor 110 is provided with a plug-in portion 111 extending into the sleeve 120. An annular limiting groove 121 is provided on the outer side of the sleeve 120. The socket 200 includes a socket body and a second connecting conductor 210. A clearance hole 220 that is plugged into the sleeve 120 is provided on one side of the upper end of the socket body. A column 221 extends in the clearance hole 220, and an insertion hole 222 is provided in the column 221. The second connecting conductor 210 is arranged in the socket body, and a conductive sleeve 211 is provided on the upper end of the second connecting conductor 210 that extends into the insertion hole 222. An opening 223 connected to the clearance hole 220 is provided on the top side of the socket body. A locking structure 230 is provided on the top side of the column 221 for locking the plug 100 inserted into the socket 200. The locking structure 230 includes an elastic support member 231 and a clamping member 232. The elastic support member 231 is connected to the top side of the column 221. The clamping member 232 is provided on the elastic support member 231. One end of the clamping member 232 is provided with a downwardly extending clamping portion 233 and the other end is provided with a pressing portion 234. The clamping portion 233 is used to clamp into the annular limiting groove 121.

[0038] Specifically, the first connecting conductor 110 of the plug is disposed within the plug body, and has an inserting portion 111 extending into the sleeve 120. A clearance hole 220 is provided on one side of the upper end of the socket body, which is inserted into the sleeve 120. A column 221 extends into the clearance hole 220, and an insertion hole 222 is provided within the column 221. The upper end of the second connecting conductor 210 has a connecting sleeve 211 extending into the insertion hole 222. Therefore, the sleeve 120 of the plug body extends into the clearance hole 220 of the socket body, and the inserting portion 111 of the plug body is inserted into the insertion hole 222 within the column of the socket, thereby connecting the first connecting conductor 110 and the second connecting conductor 210, thereby achieving electrical connection between the plug 100 and the socket 200. This structure facilitates connection and removal of the plug 100 and the socket 200, and facilitates maintenance and replacement. Because the outer side of the plug sleeve 120 is provided with an annular limiting groove 121, the top side of the socket column 221 is provided with a locking structure 230. One end of the locking structure's clamping member 232 is provided with a downwardly extending clamping portion 233, which allows the clamping portion 233 to be snapped into the annular limiting groove 121, thereby locking the plug 100 and the socket 200 and ensuring the stability of the connection. The annular limiting groove 121 allows the plug 100 and the socket 200 to rotate relative to each other, facilitating the layout of the cable in the car. The other end of the clamping member 232 is provided with a pressing portion 234. The clamping member 232 is arranged on the elastic support member 231 on the top side of the column 221. By pressing the pressing portion 234, the clamping portion 233 is separated from the annular limiting groove 121, and the lock can be unlocked, which is convenient and simple to operate.

[0039] Further, refer to Figure 6 and Figure 7 , support walls 224 are formed on both sides of the opening 223, and a support member 240 is slidably connected to the support wall 224, which is used to be limited to the bottom side of the pressing portion 234. Specifically, the support member 240 is limited to the bottom side of the pressing portion 234 of the clamping member, keeping the clamping member 232 fixed, preventing accidental contact from loosening the connection between the plug 100 and the socket 200, thereby allowing the clamping portion 233 to be locked within the annular limiting groove 121 of the plug. Because the support member 240 is slidably connected to the support arm 224, the support member 240 no longer limits the pressing portion 234 when it slides, allowing the user to press the pressing portion 234 downward, separating the clamping portion 233 and the annular limiting groove 121, thereby unlocking the plug 100 and the socket 200.

[0040] Further, refer to Figure 6 and Figure 7 A limiting member 250 is provided on the top side of the column 221. The limiting member 250 extends to both sides to the top side of the support wall 224 and forms a limiting gap 251 with the top side of the support wall 224. A guide portion 241 extends from the support member 240 and extends into the limiting gap 251. Specifically, because the limiting member 250 forms a limiting gap 251 with the top side of the support arm 224, the guide portion 241 extends from the support member 240, so that the support member 240 slides in the limiting gap 251. Grooves are also provided on both sides of the support wall 224, and protrusions are correspondingly provided on the guide portion 241, so that when the support member 240 is in the limiting gap 251, the protrusions engage with the grooves, allowing the support member 240 to slide and stabilize both sides of the support arm 224, thereby preventing the support member 240 from slipping and being lost.

[0041] Further, refer to Figure 5 and Figure 8 The second connecting conductor 210 includes a connector 212, a conductive sleeve 211 disposed at the upper end of the connector 212, and a connecting sleeve 213 disposed at the lower end of the connector 212. The connecting sleeve 213 connects to the conductive wire 300. The connecting sleeve 213 is arranged perpendicular to the conductive sleeve 211. Specifically, the connecting sleeve 213 of the second connecting conductor connects to the conductive wire 300 to enable power transmission. The perpendicular arrangement of the connecting sleeve 213 and the conductive sleeve 211, which allows the conductive wire 300 to be positioned perpendicular to the conductive sleeve 211, helps reduce bending or twisting of the line, reduces damage to the conductor, and improves line safety.

[0042] Further, refer to Figure 8 The connecting sleeve 211 is formed by stamping and stretching at the upper end of the connecting piece 212, and the connecting sleeve 213 is formed by rolling at the bottom end of the connecting piece 212. Specifically, by increasing the area of the second connecting conductor 210, the contact surface with the first connecting conductor 110 and the wire 300 is increased, thereby improving the reliability of power transmission.

[0043] Further, refer to Figure 9 and Figure 10An elastic sleeve 260 is also provided inside the conductive sleeve 211. The elastic sleeve 260 is distributed with a plurality of through slots 261. Elastic arms 262 are formed between adjacent through slots 261. The elastic arms 262 bend toward the center of the elastic sleeve 260. A limiting ring 214 is also provided at the mouth of the conductive sleeve 211 for limiting the elastic sleeve 260. Specifically, the elastic arm 262 bends toward the center of the elastic sleeve 260 to ensure that the first connecting conductor 110 of the plug is inserted into the insertion hole 222 and connected to the elastic sleeve 260, thereby realizing the transmission of electrical energy between the conductors and avoiding the first connecting conductor 110 and the second connecting conductor 210 from being directly tightly fitted and affecting the separation and damaging the contact surface of the conductors. A limiting ring 214 is provided at the mouth of the conductive sleeve 211 to limit the elastic sleeve 260. When the plug portion 111 is inserted into the sleeve 120 , the retaining ring 214 and the plug portion 111 are sealed to prevent the heat generated during power transmission from causing the plastic of the plug body and the socket body to melt into the conductive sleeve 211 and affect current transmission.

[0044] Further, refer to Figure 9 A plug 270 is also mounted on the end of the elastic sleeve 260 away from the retaining ring 214. A retaining flange 271 is provided at the end of the plug 270, which is retained outside the conductive sleeve 211. Specifically, the retaining flange 271 of the plug is retained outside the conductive sleeve 211, sealing the conductive sleeve 211 and preventing the plastic of the socket body from melting when heated and entering the conductive sleeve 211, which could affect current transmission.

[0045] Further, refer to Figure 9 The elastic sleeve 260 is stamped with a plurality of inwardly extending limiting portions 263. The outer wall of the plug 270 is provided with a slot 272, which engages with the limiting portions 263. Specifically, the slot 272 engages with the limiting portions 263, so that the plug 270 and the elastic sleeve 260 are stably connected and fixed in the guide sleeve 211.

[0046] Further, refer to Figure 10 The outer side of the column 221 is further provided with a sealing groove 225, and a sealing ring is provided in the sealing groove 225. Specifically, the sealing ring ensures the sealing of the connection between the plug 100 and the socket 200, and plays a waterproof role.

[0047] Further, refer to Figure 3 The plug body is provided with a connecting flange 130, and a sealing gasket 131 is provided on one side of the connecting flange 130. Specifically, the sealing gasket 131 can prevent water from entering the plug body and avoid short circuit of the internal circuit when water is encountered.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
