The invention relates to a current impedance weakening joint of a charging gun of a charging pile, the weakening joint comprises: a charging pile cable, a charging gun, a handle, a fixed switch, a impedance weakening joint, wherein the end of the charging pile cable is fixedly connected with bottom end of the charging gun, upper end of the charging gun is provided with with handle and is an integrated structure, right side of the the handle is in embedded installation with the fixed switch. The weakening joint has following beneficial effects: when the charging gun of the charging pile chargesan electric vehicle, the impedance weakening joint is inserted into a socket of the electric vehicle, so that a current column in the socket is rotationally shrunk and fixed by a alternating currentframe under buffering of a support column, so that the current contact on the alternating current frame is in contact and electrified with the current column under a suitable force, the rotation of the alternating current frame is used to attach outer wall of the current column, to avoid an impact caused by plug-in and plug-out during charging, leading to deformation of the outer wall of the current column or other alternating current components, thereby reducing a risk of poor contact when charging the electric vehicle, and effectively transmitting current to the electric vehicle to avoid excessive consumption of current impedance.
Description
technical field [0001] The invention relates to a current impedance weakened joint of a charging gun of a charging pile, and relates to the field of automobile charging piles. Background technique [0002] Car charging pile, a device for charging electric vehicles, can be fixed on the ground or walls, installed in public buildings and residential area parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. [0003] However, because the plug of the charging gun of the charging pile is composed of several grooves and matching metal current columns, the metal columns are deformed during long-term plugging and socket bumping. Although they can still be used, the deformed current columns may be different from the interface. The contact of the shrapnel is unstable, which will lead to poor contact. Poor contact will cause the current impedance to increase, so that the current will lose a lot of part in the impedanc...
