Abstract

A cable connection structure includes a pair of power cables, each having a conductor, and a sleeve being cylindrical and connecting the conductors of the pair of power cables, the sleeve including multiple first indents recessed in radial directions of the sleeve and located at positions separated from each other on a first outer circumference of the sleeve, and multiple second indents recessed in the radial directions of the sleeve and located at positions separated from each other on a second outer circumference that is different from the first outer circumference in an axial direction of the sleeve, at least one indent among the multiple indents arranged along a circumferential direction of the sleeve having a depth different from depths of other indents on the outer circumference of the sleeve.

Abstract

A connector is configured to be connected to an inlet of an electric apparatus having a storage battery. The connector includes a main body portion, an insertion portion, a first arm, a first preloading member, a release member, a solenoid, and a slide member. The slide member includes a support piece configured to come into contact with a back surface of a first front portion and a connection piece connecting a plunger and the support piece. The connection piece includes a first connection piece provided on a side of the plunger and a second connection piece provided on a side of the support piece. The support piece and the first connection piece are provided with a shift in position in a left-and-right direction.
