Description

Energy storage elbow connector

Technical Field

The utility model relates to the field of connectors, in particular to an energy storage elbow connector.

Background Art

When electric vehicles are produced, connectors are often required for wiring operations. Connectors generally include plugs and sockets, through which different cables are electrically connected. The plug can be inserted into the socket so that the male terminal is electrically connected to the female terminal. In current technology, the plugs and sockets of some elbow connectors are fixedly installed by plugging and snap-fitting. When the user installs the socket and plug multiple times, the connection position of the socket and plug is easily worn or damaged during the force application process, which is not conducive to later use. In addition, existing connectors are generally designed for fixed standard cables and cannot adapt to cables of various specifications.

Therefore, an elbow connector is provided which can adapt to cables of different specifications and in which the plug and the socket are not easily separated.

Preferably, the socket further comprises a waterproof pad, and the waterproof pad is arranged in the middle part of the socket body.

The working principle of the utility model is as follows: when the plug back cover is installed on the plug body, the driving structure of the plug back cover will contact the wire clamping element. Since the driving structure is a conical surface and will gradually shrink, as the plug back cover shrinks from the socket copper bar, the driving structure applies pressure to the outer peripheral surface of the wire clamping element, and the clamping claws of the wire clamping element gather together under the action of pressure to clamp the cable. The wire clamping element clamps and fixes the cable, and can clamp and fix cables of different specifications, and the applicable range of cable specifications can be further changed by simply replacing the wire clamping element and the plug back cover.

The locking block is stuck in the first annular groove, and the locking block can prevent the socket body from displacing along the axis of the plug copper bar, preventing the socket body from detaching from the plug body.

The beneficial effects of the utility model are as follows: the driving structure applies pressure to the outer peripheral surface of the clamping element, so that the clamping element clamps and fixes the cable, and can clamp and fix cables of different specifications, with strong adaptability. The plug and the socket are fixed by a locking button, and the locking button limits the movement of the socket along its axis, preventing the socket body from being separated from the plug body, and the connection is tight and reliable.
