[0068] In this embodiment, please refer to ​ and ​ , ​ is ​ an assembled structure schematic diagram of the housing 110 and the locking assembly 300 of the charging gun 1000 shown in the figure. ​ is ​ a partial cross-sectional view during the assembly of the housing 110 and the locking assembly 300 shown in the figure.

[0069] The locking assembly 300 is mounted on the housing assembly 100. Specifically, the locking member 310 is mounted within the first sub-slot 114a of the mounting slot 114 of the housing 110 through methods including, but not limited to, bonding, welding, or threaded connections. Driven by the second rubber core 370, the first conductive member 350, the second conductive member 360, the third connector 320, and the fourth connector 330 pass through the through-hole 1141 of the second sub-slot 114b and into the receiving cavity 113. Alternatively, the third connector 320 and the fourth connector 330 are located in the receiving cavity 113. One end of the first conductive member 350 extends into the receiving cavity 113 and is electrically connected to the third connector 320. The opposite end of the first conductive member 350 passes through the through-hole 1141 and is electrically connected to the locking member 310. One end of the second conductive member 360 extends into the receiving cavity 113 and is electrically connected to the fourth plug connector 330 , and the other end of the second conductive member 360 passes through the through hole 1141 and is electrically connected to the locking member 310 .

[0070] The second seal 340 is sealingly positioned within the second sub-groove 114b of the mounting groove 114. The projection of the second seal 340 along the negative Z-axis overlaps the projection of the via 1141 along the negative Z-axis. The second seal 340 sealingly abuts the bottom surface of the second sub-groove 114b of the mounting groove 114. The third protrusion 343 of the second seal 340 sealingly abuts the side surface of the second sub-groove 114b. In this embodiment, the second seal 340 helps improve the sealing effect of the charging gun 1000.

[0071] After the locking assembly 300 is installed, the cover plate 120 of the housing assembly 100 is mounted on the outer shell 110 to seal the mounting groove 114. Specifically, the cover plate 120 is snap-fitted and threadedly connected to the outer shell 110. The two support plates 121 of the cover plate 120 extend into the second sub-groove 114b of the mounting groove 114 and abut against the end surface of the second sealing member 340 facing away from the bottom surface of the second sub-groove 114b, thereby limiting the position of the second sealing member 340. This simple structure provides a better sealing effect.

[0072] Please refer to ​ 、 ​ and ​ , ​ yes ​ FIG. 1 is a schematic diagram of the assembly structure of the conductive component 200 and the housing component 100 of the charging gun 1000 . ​ yes ​ A partial cross-sectional view of a charging gun 1000 is shown. ​ yes ​ An enlarged view of point A in the charging gun 1000 is shown.

[0073] The conductive component 200 is installed on the housing component 100. Specifically, the first rubber core 285 drives the first plug-in component 260 and the second plug-in component 270 to extend into the receiving cavity 113 from the first opening 1131, and the first rubber core 285 is plugged into the second rubber core 370 located in the receiving cavity 113. Furthermore, the first plug-in component 260 is plugged into the third plug-in component 320 to achieve fixed connection and electrical connection, and the second plug-in component 270 is plugged into the fourth plug-in component 330 to achieve fixed connection and electrical connection, thereby realizing the electrical connection between the mating terminal 250, the locking member 310, and the conductive cable 280.

[0074] One end of the conductive cable 280 away from the plug rubber core 210 penetrates into the receiving cavity 113 from the first opening 1131, then passes through the second opening 1132 to the outside of the receiving cavity 113. The mounting seat 220 extends into the receiving cavity 113, and one end of the plug rubber core 210 extends into the receiving cavity 113. And, by means including but not limited to snap connection, bonding, or threaded connection, one end of the plug rubber core 210 is fixedly connected to the mounting portion 110a of the outer shell 110.

[0075] The first seal 130 is sleeved on the conductive cable 280, and the second protrusion 1313 on the inner peripheral surface of the first seal 130 seals and abuts against the outer peripheral surface of the conductive cable 280. It can be understood that the first seal portion 131 and the second seal portion 132 seal and abut against the outer peripheral surface of the conductive cable 280. In this embodiment, by providing the second protrusion 1313, the compression amount when the first seal 130 abuts against the outer peripheral surface of the conductive cable 280 is increased, thereby improving the sealing effect. When the second protrusions 1313 are multiple, the contact area between the first seal 130 and the conductive cable 280 is increased, making the sealing effect better.

[0076] The inclined guiding portion 133 and the second seal portion 132 sequentially extend into the receiving cavity 113 from the second opening 1132. The second outer peripheral surface 1321 of the second seal portion 132 faces away from the conductive cable 280, and the first protrusion 1322 ([ ​ ) on the second outer peripheral surface 1321 seals and abuts against the inner peripheral surface of the receiving cavity . The stepped surface 1312 of the first seal portion 131 seals and abuts against the abutting end surface 112 of the handheld portion 110b. In this embodiment, by providing the inclined guiding portion 133, the first seal 130 is more easily extended into the receiving cavity 113, facilitating assembly. By providing the first protrusion 1322, the compression amount when the first seal 130 abuts against the inner peripheral surface of the receiving cavity 113 is increased, thereby improving the sealing effect.

[0077] In the X-axis direction, the end cap 140 is fixedly connected to the outer shell 110, and the end cap 140 is installed at one end of the handheld part 110b away from the installation part 110a. Specifically, the end cap 140 is sleeved on the conductive cable 280, and the threaded hole 143 of the end cap 140 is threadedly connected to the external thread of the handheld part 110b to achieve a fixed connection. Among them, in the X-axis direction, the through hole 141 communicates with the receiving cavity 113, and the sealing groove 142 communicates with the receiving cavity 113. It can be understood that the conductive cable 280 passes through the receiving cavity 113 and the through hole 141. The second groove wall surface 1422 of the sealing groove 142 of the end cap 140 is spaced opposite to the abutting end surface 112 of the handheld part 110b. It can be understood that a sealing groove 142 is provided on the inner peripheral surface of the through hole 141 of the end cap 140 near the abutting end surface 112.

[0078] Correspondingly, the first seal 130 is sealingly positioned in the sealing groove 142 of the end cap 140. Specifically, the first sealing portion 131 of the first seal 130 is sealingly positioned in the sealing groove 142. The first outer peripheral surface 1311 of the first sealing portion 131 faces away from the conductive cable 280. The first groove wall surface 1421 of the sealing groove 142 faces the first outer peripheral surface 1311 of the first seal 130. The first outer peripheral surface 1311 is sealingly abutted against the first groove wall surface 1421 of the sealing groove 142. The end surface of the first sealing portion 131 facing away from the second sealing portion 132 is sealingly abutted against the second groove wall surface 1422 of the sealing groove 142. That is to say, the first seal 130 is sealingly clamped between the conductive cable 280, the outer shell 110 and the end cap 140, so that a sealed state is maintained between the conductive cable 280, the outer shell 110 and the end cap 140.

[0079] In this embodiment, the sealing between the conductive cable 280, the outer shell 110 and the end cap 140 can be achieved through the first seal 130. The structure is simple, the cost is low, and it is more convenient for users to repair.

[0080] By setting the first seal 130 as the first sealing portion 131 and the second sealing portion 132, and the second sealing portion 132 extends into the receiving cavity 113, the abutting area of the first seal 130 with the outer shell 110, the end cap 140 and the conductive cable 280 is larger, thereby improving the sealing effect.

[0081] By setting the inclined first outer peripheral surface 1311 to abut against the inclined first groove wall surface 1421, the first groove wall surface 1421 can limit the first seal 130 to prevent the first seal 130 from loosening, thereby ensuring that the first seal 130 has a good sealing effect for a long time.

[0082] By setting the second groove wall surface 1422 to abut against the first seal 130, the second groove wall surface 1422 positions the first seal 130 to prevent the first seal 130 from loosening, thereby ensuring that the first seal 130 has a good sealing effect for a long time.

[0083] In this embodiment, the locking member 310 can be a mechanical lock or a microswitch. When the charging gun 1000 is inserted into the charging port of the electrical device, the locking member 310 is opened so that the charging gun 1000 is locked to the charging port of the electrical device to prevent the charging gun 1000 from falling off. And by using a plug-in connection to connect the locking member 310, the locking member 310 can be disassembled, which is convenient for maintenance and replacement. When the locking member 310 is installed in the installation groove 114, since the bottom surface of the installation groove 114 faces away from the cavity wall surface of the receiving cavity 113, it is beneficial to avoid signal interference.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application.
