The present invention relates to a rapid explosion-proof charging gun. The charging gun comprises a plug component and a socket component. The socket component comprises a self-locking structure. Theself-locking structure comprises an installing plate, a pulling rod, a pulling ring arranged at the rear of the pulling rod, a stopping block arranged at the front part of the pulling rod, and a spring sleeving the pulling rod. The inner part of the installing plate is a groove, the groove is provided with a through hole, the pulling rod penetrates the through hole, and the pulling rod can slide forward and backward relative to the through hole. The stopping block can slide forward and backward relative to the groove of the installing plate. One end of the spring contacts with the groove of the installing plate, and the other end of the spring contacts with the stopping block. The plug component comprises a guiding groove, the guiding groove is arc-shaped, and one end of the guiding grooveis provided with clamping slot. The pulling rod can slide along the guiding groove, and when the front end of the pulling rod is inserted in the clamping slot, the plug component and the socket component are locked. According to the charging gun, by using the structure, the installation and the dismantling are convenient, and the connection efficiency is improved.

The invention discloses an automobile charging socket. The automobile charging socket includes a base having an inner cavity, a plurality of contact terminals are arranged in the inner cavity of the base, each contact terminal has an insertion hole used for insertion of a contact pin of charging equipment, and at least one circle of conductive wire which is used for contact with the contact pin and is in the shape of a spiral spring is arranged inside the insertion hole. The automobile charging socket provided by the invention adopts the conductive wire in the shape of a spiral spring to contact with the contact pin of the charging equipment for conduction, thus a contact area of the contact pin of the charging equipment and the conductive wire during charging can be greatly increased, contact resistance of the contact pin of the charging equipment is reduced, and a temperature rise is lowered. By adoption of the conductive wire in the shape of a spiral spring, the contact pin of the charging equipment and the conductive wire have a certain buffering effect, and thus the plugging and unplugging life of the contact pin can be greatly prolonged.

The invention relates to a signal connector used for print circuit boards, comprising a plug and a socket; wherein the plug comprises a plug insulating body and a plug contact. The plug insulating body is internally provided with a contact containing cavity, and the plug contact comprises an insertion contact component and a weld line contact component, wherein the weld line contact component is fixedly arranged at the rear end of the contact containing cavity, the insertion contact component coaxially thrusts and is arranged at the front end of the contact containing cavity. An insertion contact component radial wobble clearance is arranged between the insertion contact component and the contact containing cavity, a pressure spring is arranged between the weld line contact component and the insertion contact component, and axial space is arranged between the weld line contact component and the insertion contact component.

The invention discloses a bus-bar connector which comprises a rubber core and a conductive terminal, wherein a channel penetrating through the terminal is formed in the terminal; the front and rear ends of the channel are matched with a male plug-in pin; the rear end of the terminal is fixedly connected with a pin tail; two first elastic pieces opposite to each other and two second elastic piecesopposite to each other are respectively fixedly arranged at the front end of the channel; third elastic pieces corresponding to the first elastic pieces one by one are fixedly arranged at the rear endof the channel; one first elastic piece and the corresponding third elastic piece are connected by virtue of a fourth elastic piece arranged between the two; contact surfaces in contact fit with themale plug-in pin are arranged on the first elastic pieces, the second elastic pieces, the third elastic piece and the fourth elastic piece. The bus-bar connector disclosed by the invention has the beneficial effects that the contact stability, contact reliability, plug-in force and plugging / unplugging life between the terminal and the male plug-in pin can be effectively improved, and a plugging bias phenomenon caused while plugging the terminal and the male plug-in pin is avoided.

The invention discloses a charging connector and wire harness assembly for an electric vehicle and a hybrid electric vehicle. The charging connector and wire harness assembly comprises a plug part and a socket part. The plug part comprises a metal inserting core, and the socket part comprises a metal inserting sleeve. The shape of the periphery of the metal inserting core is matched with that of the interior of the metal inserting sleeve, and the metal inserting core is arranged to be cylindrical. A rubber inserting core is assembled in an inner cavity of the cylindrical metal inserting core, and the length of the rubber inserting core is larger than the length of the cylindrical metal inserting core. A rubber inserting sleeve is arranged on the periphery of the metal inserting sleeve in a sleeved mode. Compared with the prior art, the charging connector and wire harness assembly for the electric vehicle and the hybrid electric vehicle has the advantages that the rubber inserting core and the rubber inserting sleeve play a role of buffering and rigid collision is prevented.
