An improved floating connector can be employed for, among other things, connecting a traction battery to the drive of an electrically-driven vehicle. The self-aligning floating connector can be used to mate connectors of the battery and the electric drive despite misalignment. The floating connector has a frame and a contact housing movable inside an aperture of the frame. The contact housing is rotatable about an axis that extends perpendicularly to the surface defined by the aperture. The essentially oval outer surface of the contact housing can cooperate with the aperture to provide a limit stop for the relative movement of the contact housing and the frame. The angular movement of the contact housing inside the aperture can be sterically constrained to limit the rotation of the contact housing relative to the frame to a pre-defined angular range. A system with a floating connector and a mating connector is also disclosed.

The lock includes a shaft portion. The lock receiving portion includes a bottom surface opposite to the shaft portion in the axial direction thereof and a side surface for guiding the rotation of the shaft portion. At least one of the lock piece and the lock receiving portion includes a spring portion that presses the shaft portion toward the bottom surface.

The invention provides a double-breakpoint moving contact apparatus. The apparatus comprises a moving contact limiting component, a first moving contact shaft, a first moving contact spring, a second moving contact spring, a first limiting component shaft, a second limiting component shaft and a moving-contact contact blade. The moving contact limiting component and a moving contact shell form a moving contact installation space. The first limiting component shaft is arranged on an upper end surface of an inner side of the moving contact limiting component. The second limiting component shaft is arranged on a lower end surface of the inner side of the moving contact limiting component. The first moving contact spring sleeves the first limiting component shaft. One end of the first moving contact spring is connected to the upper end surface of the inner side of the moving contact limiting component and the other end is connected to an upper side surface of the moving-contact contact blade. In the invention, a rotary-type double-breakpoint structure is adopted; the moving-contact contact blade adopts a multiple-piece type and a model with main and auxiliary contacts. Through using the double-breakpoint structure, a short-circuit connection and disconnection capability of a product can be effectively increased. Through using a multiple-piece type contact structure, a short time connection and short-term tolerance capability can be increased. And damages of an arc to a main contact can be reduced.
