Example 1

As shown in fig. 1-2, a charging gun plug and a charging gun mainly comprise a charging gun body 100 and a plug 200 assembled at the front end of the charging gun body through bolt fastening, wherein the plug 200 comprises a shell 21 and a base 22 clamped in the shell 21, and a plurality of through holes 221 and connecting terminals 300 with different sizes are arranged on the base 22, namely, the connecting terminals 300 are clamped through the through holes 221.

Specifically, as shown in fig. 3 to 5, a connecting wall 222 extending to one side of the housing 21 is provided at each through hole 221, a plurality of convex walls 223 are provided around the opening of the connecting wall 222 and gathered inwards in the circumferential direction at the end of the connecting wall 222, a stopper 224 is provided on the inner surface of the end of the convex wall 223, and a hole corresponding to the through hole 221 in the base 22 is provided on the housing 21. The channel includes a first connecting cavity 211 for mating with an external connector and a second connecting cavity 212 for positive engagement with a raised wall 223.

The second connecting cavity 212 is further provided with a clamping groove 2121 for clamping the sealing ring and a through groove 213 communicated with the first connecting cavity 211, when the base 22 is connected with the housing 21, the front end of the convex wall 223 is inserted into the second connecting cavity 212 and fixed under the limit of the wall, i.e. the convex wall 223 can not expand and rotate outwards any more.

As shown in fig. 6, two pin positioning seats are provided on the terminal, and a limit region 33 matched with the limit block 224, namely a first pin positioning seat 31 and a second pin positioning seat 32, is formed between the two pin positioning seats.

Specifically, the side of the stopper 224 near the connecting wall 222 is an inclined surface 2241, i.e. the lower portion of the stopper 224 is the inclined surface 2241 and the top portion is the flat surface 2242. When in use, the connection terminal 300 is inserted from the rear side of the base 22 (the side where the connection wall 222 is disposed is the front side), after the connection terminal 300 passes through the convex wall 223, the first pin positioning seat 31 at the forefront is mutually structured with the inclined surface 2241 first, under the action of pressure, the convex wall 223 is opened outwards, and when the limiting block 224 is in the limiting region 33, the limiting block is quickly rebound and clamped.

At this time, the flat surface 2242 is used to abut against the first pin positioning seat 31 to prevent the terminal from retreating, and the fitting is completed after the base 22 is connected to the housing 21, that is, after the convex wall 223 is inserted into the second connection chamber 212.

Further, a sealing ring is sleeved on the terminal, the sealing ring is sleeved on the front side part of the first contact pin positioning seat 31, and when the base 22 is assembled with the shell 21, the sealing ring is just embedded in the clamping groove 2121 of the second connecting cavity 212. The sealing ring is in interference fit with the clamping groove 2121, and the gap between the barrel groove and the connecting terminal 300 is fully filled through the pressure of the sealing ring, so that liquid is effectively prevented from penetrating into the second connecting cavity 212 from the first connecting cavity 211, and the overall waterproof effect is greatly improved.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
