In one embodiment, as shown in fig. 2, 3 and 4, the cover 22 has a second groove 221 on an outer wall of an end thereof adjacent to the slot of the insertion slot 211, and each terminal assembly 2 further includes a second sealing ring 23, and the second sealing ring 23 is accommodated in the second groove 221 and abuts against an inner wall of the first accommodating cavity 111.

It can be understood that, by providing the second groove 221 on the outer wall of the cover 22 and installing the second sealing ring 23 in the second groove 221, the second sealing ring 23 abuts against the inner wall of the first accommodating cavity 111, so that water or vapor is effectively prevented from entering the connection between the socket terminal 13 and the terminal assembly 2 from between the wall of the first accommodating cavity 111 and the cover 22, which results in the failure of the charging socket 100. In the present embodiment, the overall waterproof performance of the charging inlet 100 can be improved to the IP67 level.

In this embodiment, the protruding first protruding one end that holds chamber 111 of closing cap 22 is equipped with the boss, and the boss extends towards the radial direction of closing cap 22 to make the boss form second recess 221 with the outer wall cooperation of closing cap 22, locate on terminal 21 when closing cap 22 cover, and when stretching into first chamber 111 that holds, the boss with the first spacing butt of the opening tip that holds chamber 111, thereby make the sealed first opening that holds chamber 111 of second sealing washer 23, effectively improve sealed effect.

In one embodiment, as shown in fig. 2, 3 and 4, the cover 22 is provided with a locking groove 222 and a sliding groove 223 communicated with the locking groove 222, the inner wall of the first accommodating cavity 111 is provided with a boss 112, and the boss 112 slides into the locking groove 222 through the sliding groove 223.

It is understood that the mounting of the terminal assembly 2 in the first accommodating chamber 111 is achieved by the snap-fit engagement of the boss 112 and the card slot 222 by providing the card slot 222 on the cover 22 of the terminal assembly 2 and providing the boss 112 on the inner wall of the first accommodating chamber 111. Further, by providing the slide groove 223 communicating with the card slot 222, the terminal assembly 2 is facilitated to be easily installed in the first accommodating chamber 111 through the slide groove 223. In this embodiment, when the terminal assembly 2 is installed in the first accommodating cavity 111, the boss 112 slides into the slot 222 through the sliding slot 223, so that the terminal assembly 2 is installed in the first accommodating cavity 111 through the matching between the slot 222 and the boss 112.

When the terminal assembly 2 is mounted in the first accommodating cavity 111 by the engagement of the card slot 222 and the boss 112, and one end of the terminal 21 is inserted into the mounting groove 131 of the receptacle terminal 13, the fastener 3 is inserted through the through hole 212 and the mounting hole 132 of the terminal 21, so that the terminal assembly 2 and the receptacle terminal 13 are stably mounted.

In use, the portion of the charging socket 100 that fails, which is usually in contact with the pins of the charging gun, is the insertion groove 211 of the terminal assembly 2. The socket terminal 13 is connected to the terminal assembly 2, and electrically conducted to thereby form a charging path. When the terminal assembly 2 needs to be replaced, the terminal assembly 2 of the charging socket 100 can be replaced by removing the fastener 3 and then directly removing the terminal assembly 2 from the mounting groove 131 of the socket assembly 1 for replacement.

The utility model discloses a socket 100 charges through passing through fastener 3 with terminal subassembly 2 and socket terminal 13 and realizing fixed connection, can ensure that the area of contact of terminal subassembly 2 and socket terminal 13 is inseparable and electrically conductive high-effect, is favorable to reduceing the temperature rise that produces between this two parts. Through set up first sealing washer 14 between the chamber wall in socket terminal 13 and first chamber 111 that holds, usable first sealing washer 14 prevents that rainwater, dust from getting into socket subassembly 1's line ball region, under the common guarantee of the rear end seal line body, can make socket subassembly 1 whole protection level reach IP67 level. The problem of overhigh temperature rise of the terminal assembly 2 is simply and effectively solved by increasing the contact area between the terminal assembly 2 and the socket terminal 13.

In the present embodiment, the terminal assembly 2 is reversely unlocked, the terminal assembly 2 is taken out, and a new terminal 21 is replaced, using a special tool; in the installation process, the terminal 21 is firstly installed in the installation groove 131 of the first accommodating cavity 111 and pressed in place, the fastener 3 penetrates through the through hole 212 and the installation hole 132, the fastener 3 is screwed, then the second sealing ring 23 is installed, and finally the sealing cover 22 is rotated in the locking direction, so that the fixation and the locking are completed, and the assembly efficiency is effectively improved.
