Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model relates to a charging socket, including socket portion 1 and spring 2, socket portion is equipped with a plurality of upper contact piece 3 and a plurality of lower contact piece 4, and upper contact piece is equipped with interior convex part 5 in, and the back of going up interior convex part is equipped with recess 6, and spring mounting is in the recess, and lower contact piece is equipped with interior convex part 7 down. The upper contact piece and the lower contact piece are both of sheet structures with certain lengths, so that shaking type elastic deformation can occur to the upper contact piece and the lower contact piece, and the charging plug is convenient to connect and install. And the length of the upper contact piece is greater than that of the lower contact piece, so that the upper contact piece is easily subjected to plastic deformation after the structure is repeatedly plugged, and the upper inner convex part of the upper contact piece cannot be contacted with the charging plug. And the spring supplements the upper inner convex part and keeps the upper inner convex part in contact with the charging plug. Go up interior convex part and interior convex part homoenergetic down and contact with charging plug, increase electrically conductive area.

A common embodiment is that the number of upper and lower contacts is 3.

According to the above embodiment, preferably, the plurality of upper contact pieces and the plurality of lower contact pieces are wound into the circular holes, the lower contact pieces are located between the adjacent upper contact pieces, the upper inner convex portions and the lower inner convex portions are located inside the circular holes, and the grooves are located outside the circular holes. The embodiment discloses a specific structure of an upper contact piece and a lower contact piece. The round hole is used for accommodating an inserted charging plug.

According to the above embodiment, preferably, the adjacent upper contact pieces constitute the rectangular through groove, and the lower contact piece is located in the rectangular through groove. The present embodiment discloses a relative positional relationship of an upper contact piece and a lower contact piece.

According to the above embodiment, preferably, the grooves of the plurality of upper contact pieces constitute the annular groove in which the spring is mounted. The embodiment discloses a concrete connection mode of spring and recess, and the spring twines in the annular groove, for the upper contact piece provides radial force, compensates rocking of upper contact piece, keeps the contact of upper contact piece and charging plug.

According to the above embodiment, it is preferable that the spring further comprises a housing 8 covering the upper contact piece, the lower contact piece and the spring, the housing is fixedly connected with the socket portion, and the housing is provided with a through hole 9. The shell can protect the whole socket structure, and prevents impurities from falling into the socket part to influence the product performance. The shell and the socket part can be connected through threads, and the shell is convenient to detach and maintain.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
