Abstract: A plug includes a housing, a plurality of plug shells that are accommodated in the housing in a manner to protrude from the housing by a predetermined length A, a plurality of plug bodies that are accommodated in the plug shells respectively, and a plurality of plug contacts that are fixed to the plug bodies respectively. A receptacle includes a receptacle shell, a receptacle body, and a receptacle contact. The receptacle shell includes: an accommodation portion that entirely accommodates ends of the plurality of plug shells protruding from the housing, and whose insertion-direction length B satisfies B<A.

Abstract: A vehicle electrical connector includes an outer shell, an inner shell, and a conductive assembly. The outer shell includes a groove and assembling channels. The assembling channel extends from an opening on an outer side of the groove toward an inner tubular wall surface of the groove. The inner shell is in the outer shell and includes a base and a casing. The casing extends outward from one side of the base. The inner shell includes buckle blocks outside the casing. The buckle block is guided in the assembling channel through a path of the assembling channel, so that the buckle block is positioned in the assembling channel. Hence, after the inner shell is axially inserted into the outer shell and then rotated into a predetermined position, the inner shell and the outer shell can be stably held with each other.

Abstract: A female connector includes an insulating body, a terminal module, at least one elastic element and at least one lateral shell. At least one side of the insulating body defines an opening. A middle of the insulating body defines an accommodating space. The terminal module is mounted in the accommodating space. The terminal module includes a plurality of terminals. The at least one elastic element is mounted to a surface of the insulating body which is parallel to an extending direction of each terminal. The at least one elastic element has a clamping portion, and a transverse width of the clamping portion is equal to a distance between two inner surfaces of two sides of the insulating body. The at least one lateral shell is assembled to at least one side surface of the insulating body.
