As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 5, a waterproof structure of a switch of a charging gun includes:

the charging gun body 100 is provided with a groove 110, a boss 120 is arranged on the outer side of the groove 110, and a locking groove 130 is arranged on the boss 120; a micro switch 200 installed in the groove 110, and a locking hole 210 corresponding to the locking groove 130 is provided at a side of the micro switch 200; a waterproof layer 300 disposed on the bottom surface of the micro switch 200 for waterproofing the groove 110.

Specifically, this embodiment is convenient for assemble the micro switch 200 and the charging gun body 100, therefore, set up the recess 110 on the charging gun body 100, and set up the locking groove 130 on the boss 120 outside the recess 110, there is a screw thread structure in its locking groove 130, and simultaneously, set up locking hole 210 at the lateral part of micro switch 200, when assembling, install micro switch 200 in the recess 110, pass locking hole 210 through the screw simultaneously, and with locking groove 130 threaded connection, thereby can directly install micro switch 200 on the charging gun body 100, make the equipment between micro switch 200 and the charging gun body 100 convenient and simple, and improve the packaging efficiency.

Certainly, in order to enable the micro switch 200 to be assembled reasonably and quickly, the micro switch 200 in this embodiment includes a switch main body 220 and a fixing portion 230 disposed outside the switch main body 220, wherein an assembling groove 231 is disposed on a bottom surface of the fixing portion 230, and the locking hole 210 is disposed on the fixing portion 230.

When the micro switch 200 and the charging gun body 100 are assembled, the bottom of the switch main body 220 is directly inserted into the groove 110, the assembling groove 231 on the bottom surface of the fixing portion 230 covers the boss 120 on the outer side of the groove 110, and then the screw penetrates through the locking hole 210 on the fixing portion 230, so that the micro switch 200 and the charging gun body 100 can be assembled reasonably, conveniently and quickly.

Meanwhile, the cover mode of the assembling groove 231 and the boss 120 is adopted, so that liquid entering the interior of the charging gun body 100 can be prevented from flowing into the groove 110 from the side surface of the assembling position of the microswitch 200 and the charging gun body 100, and the waterproof performance between the microswitch 200 and the charging gun body 100 is effectively improved.

Referring to fig. 4 and 5, in order to better achieve the waterproof performance of the charging gun body 200 and the micro switch 100, the waterproof layer 300 is made of silica gel or PVC soft rubber, and the waterproof layer 300 includes a first waterproof portion 310 and a second waterproof portion 320, wherein the first waterproof portion 310 is disposed in the assembly groove 231, and the second waterproof portion 320 is tightly attached to the bottom side wall of the switch main body 220.

Since the micro switch 200 and the charging gun body 100 are connected with the locking groove 130 through the locking hole 210 and the screw thread by the screw, the locking hole 210 needs to be waterproof, and in this embodiment, the first waterproof portion 310 of the waterproof layer 300 is arranged in the assembly groove 231, and after the micro switch 200 and the charging gun body 100 are assembled and fixed, the fixing portion 230 and the boss 120 tightly press the first waterproof portion 310 by screwing the screw, so that the first waterproof line is realized by performing waterproof treatment on the locking hole 210 by the soft first waterproof portion 310, and the tighter the fixing portion 230 and the boss 120 press the first waterproof portion 310, the better the waterproof effect of the first waterproof portion 310 is;

in addition, referring to fig. 2, a waterproof groove 140 is further disposed on the boss 120, and the waterproof groove 140 is located between the locking groove 130 and the groove 110, so that when the first waterproof portion 310 is slightly seeped, the seeped liquid can be collected by the waterproof groove 140, and a second waterproof line is formed by the waterproof groove 140;

and after the bottom of the switch main body 220 is inserted into the groove 110, the second waterproof portion 320 forms an interference fit with the inner wall of the groove 110, the second waterproof portion 320 is tightly extruded through the outer side wall of the bottom of the switch main body 220 and the inner wall of the groove 110, so that the second waterproof portion 320 forms a third waterproof line, and finally, the waterproof effect of the groove 110 is better through the three waterproof lines, so that the waterproof performance between the micro switch 200 and the charging gun body 100 is improved.

Referring to fig. 4, the side wall of the second waterproof portion 320 is provided with a waterproof protruding grain 321, and the outer side wall of the bottom of the switch main body 220 and the inner wall of the groove 110 can better press the second waterproof portion 320 through the waterproof protruding grain 321, so as to improve the waterproof effect.

Finally, to facilitate the production of the micro switch 200 and the assembly with the charging gun body 100, the switch main body 220 and the assembly portion 230 in this embodiment are integrally formed, and to facilitate the installation and production of the waterproof layer 300, the first waterproof portion 310 and the second waterproof portion 320 are also integrally formed.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. The present invention can be smoothly implemented by those skilled in the art according to the drawings and the above description; however, those skilled in the art should understand that changes, modifications and variations can be made without departing from the scope of the present invention, which is equivalent to the present invention; meanwhile, any changes, modifications, evolutions, etc. of equivalent changes made to the above embodiments according to the essential technology of the present invention still belong to the protection scope of the technical solution of the present invention.
