[0047] Furthermore, the front side of the lamp board 22 fits against the inner wall of the inner groove 104, and the lamp beads 23 are located within the light-transmitting hole 105; preferably, the light-transmitting hole 105 is a fan-shaped hole formed by several partition ribs 107 surrounding each other. Preferably, the lamp board 22 is a PCB ring electrically connected to the PCBA board 7; the PCBA board 7 is connected to the rear side of the mounting platform 11 by screws and is located inside the cavity of the housing 3. Its beneficial effects are: this setting further simplifies the product size, and the light propagation distance is short, making the markings more eye-catching.
[0048] Furthermore, the indicator sealing ring 21 is made of transparent rubber, which is integrally connected to the outer groove 102 and the sealing ring groove 106 through secondary rubber coating; its beneficial effect is that this setting is easy to process and manufacture, and effectively simplifies assembly.

The fixing port 31 is symmetrically provided with a second through hole 32. The fixing port 31 is fitted with the fixing platform 103 and the first screw 6 passes through the second through hole 32 and is screwed into the threaded hole of the fixing platform 103 to achieve a tight connection between the two.
[0050] Furthermore, the rear mounting platform 11 of the mounting base 1 extends into the inner cavity of the housing 3, and the front side of the PCBA board 7 is electrically connected to the first sensor 9. The PCBA board 7 controls the circuit's on / off state based on the conduction or closure signal of the first sensor 9.
[0051] The upper surface of the mounting platform 11 has two symmetrical lugs 111 in the middle, two symmetrical screw posts 112 and a first through hole 110 at the front end, with the first through hole 110 located between the two screw posts 112.
[0052] The mechanical lock 5 includes a lock body 51, a button 52, a spring 53 and a spring seat 54. The spring seat 54 is connected to the screw hole post 112 by a screw.

[0053] Two lugs 111 are rotatably connected in the middle of the lock body 51 via a hinge 55. The left arm of the lock body 51 is equipped with a detection element 56 that cooperates with the first sensor 9. The upper end of the left arm is attached to the lower end of the button 52. The limiting post 511 on the upper surface of the right arm of the lock body 51 is sleeved with the lower end of the spring 53. The lock connector 15 on the lower surface of the right arm passes through the first through hole 110 and cooperates with the positioning hole 011 of the charging gun 01.
[0054] The charging gun 01 is inserted into the socket 100 and can push the lock connector 510 upward. The lock body 51 rotates counterclockwise and compresses the spring 53. When the insertion is completed, the positioning hole 011 is located below the lock connector 510. The spring 53 returns to its original position and causes the lock body 51 to rotate clockwise, thereby pushing the lock connector 510 to automatically fall into the positioning hole 010, realizing the locking action of the lock body 51.
[0055] Pressing button 52 compresses the spring 53 of the lock body 51, causing it to rotate clockwise. The lock connector 510 disengages from the positioning hole 010 and unlocks. The detection element 56 approaches the first sensor 9 and generates a signal. The PCBA board 7 controls the circuit's on / off state based on the conduction or closure signal of the first sensor 9. Pulling out the charging gun 01 causes the spring 53 to return to its original position counterclockwise, allowing the lock body 51 to rotate counterclockwise and reset.
[0056] The detection element 56 is a magnetic component, a blocking post, or a proximity block, and the first sensor 9 is a magnetic sensor, a photosensitive sensor, or a proximity switch.
[0057] The advantages of this mechanical lock 5 are: compact overall structure, easy operation, good locking performance, and high security performance.
[0058] Furthermore, a protective cover 8 is rotatably connected to the front end of the socket. The beneficial effect of this design is that it further enhances safety protection performance.
[0059] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
