[ detailed description ] embodiments

Referring to fig. 1 to 5, an electrical connector assembly is disclosed, which includes a waterproof cover 10 and an electrical connector 20, wherein the waterproof cover 10 needs to prevent water from entering the electrical connector 20 during a waterproof test, and meets the plugging requirement. The waterproof cover 10 comprises a cylindrical part 11 with one end open and a cover plate 12 positioned at the other end of the cylindrical part 11, and the improvement is that: an inner convex ring 101 is inwardly provided on the inner wall surface of the cylindrical portion 11, and an outer convex ring 102 is outwardly provided on the outer wall surface of the cylindrical portion 11.

Specifically, the inner collar 101 and the outer collar 102 are offset from each other in the axial direction thereof, the outer collar 102 is located at a position near the opening of the cylinder part 11, and the inner collar 101 is located at a middle position of the cylinder part 11. The cover plate 12 includes an operating portion 121 extending outward from an edge thereof. The inner wall surface of the cylindrical part protrudes inwards to form a fool-proof part 110, and the fool-proof part 110 is vertically crossed with the inner convex ring 101.

The electrical connector 20 includes a front surface 201, a receiving cavity 202 penetrating the front surface 201, and a first cavity surface 220 and a second cavity surface 210 enclosing the receiving cavity. The electrical connector includes an outer cylinder 21 and a mating portion 22, and the receiving cavity 202 is formed between the outer cylinder 21 and the mating portion 22 and is used for receiving the waterproof cover 10. The first cavity surface 220 is formed as an outer wall surface of the abutting portion 22, and the second cavity surface 210 is formed as an inner wall surface of the outer tube portion 21.

After the fitting, the cover plate part 12 of the waterproof cover 1 tightly contacts and seals the front end surface 201 to prevent water from entering the electric connector 20; the cylinder portion 11 is inserted into the accommodation chamber 202, and the abutting portion 22 is inserted into the cylinder portion 11. The inner convex ring 101 is abutted to the first cavity surface 220 inwards, the outer convex ring 102 is abutted to the second cavity surface 210 outwards, namely, two opposite surfaces of the accommodating cavity 202 are provided with waterproof convex ring abutted parts, so that the waterproof area and the waterproof stroke are increased, small water drops are prevented from flowing into the accommodating cavity 202 through the front end surface 201, and meanwhile, the requirement of the insertion and extraction force can be met. The abutting portion 22 is recessed inward with a recessed portion, and the fool-proof portion 110 of the cylindrical portion 11 and the recessed portion are fitted to each other to achieve accurate insertion.

Referring to fig. 6-7, another electrical connector 300 is disclosed, which comprises a body 30, two waterproof rings 301 are sleeved on the outer surface of the body 30, and the two waterproof rings 301 are simultaneously matched with a butting connector to increase the waterproof stroke.
