Preferably, a plurality of buckles 122 for connection are arranged on the outer wall of the assembly end 12, and the buckles 122 are close to the sealing limit groove 121 and are symmetrically distributed. In this way, when the fitting is connected with the assembly end 12 of the connector body 1 through the buckle 122 and is pressed on the sealing ring 2, the sealing ring 2 can be ensured to be uniformly stressed, and the problem of air leakage of the vehicle connector due to nonuniform stress of the sealing ring 2 is further avoided. Preferably, a limiting slot 1221 is provided on the clamping surface of the buckle 122 facing the connecting portion 13. In this way, the limiting clamping groove 1221 is arranged on the clamping surface of the buckle 122 facing the connecting part 13, and the limiting clamping groove 1221 can be used for limiting the protruding points on the accessory in a matched manner, so that the accessory is prevented from falling off; in the assembly process, the protruding points on the fittings are clamped in the limit clamping grooves 1221, namely, the assembly is in place, and the assembly is simple and convenient. Preferably, the snap-on beginning of the snap 122 is provided with a guide chamfer 1222. Thus, during assembly, the guide inclined plane 1222 of the buckle 122 can be utilized to guide the assembly direction, thereby facilitating assembly. Preferably, the side wall of the mounting end 12 is provided with a viewing hole 123, and the viewing hole 123 opens into a positioning groove (not shown in the figure) of the terminal spring piece 31 on the snap terminal 3 on the inner wall of the mounting end 12. Thus, when the vehicle sealing connector of the utility model is assembled, whether the terminal 3 is inserted in place or not can be observed through the observation hole 123, and the assembly qualification rate of the vehicle sealing connector of the utility model can be effectively improved. Preferably, the mounting end 12 is provided with a false proof tab 124, the false proof tab 124 being formed by a lateral projection of the mounting end 12. Thus, during assembly, if the assembly position and/or direction is wrong, the error-preventing convex groove 124 can be used to prevent assembly from being misplaced by an assembler.
