[0002] In the field of batteries, it is necessary to set a connector to connect the battery cell so that the battery can be charged or discharged. In the connectors currently on the market, a plug-in portion is set at one end of the conductive terminal for plugging in the electrical device outside the battery, and a welding cup is set at the other end of the conductive terminal, and one end of the wire is welded to the welding cup, and the other end of the wire extends into the battery and is electrically connected to the battery cell. The presence of the wire will take up more space inside the battery. In addition, when repairing the connector, the wire will interfere, making it inconvenient to repair. Summary of the invention

[0003] The present application provides a connector, a connector assembly and a battery device.

[0004] The present application provides a connector, which includes a connector core and at least one first conductive terminal. The connector core is provided with at least one first mounting hole, and the first mounting hole passes through both ends of the connector core along the length direction of the connector. The first conductive terminal is positioned in the first mounting hole, and the first conductive terminal includes a first plug-in portion and a second plug-in portion located at opposite ends thereof. The first plug-in portion is used to plug with one of the external connection sockets, and the second plug-in portion is used to plug with the other external connection socket.

[0005] The present application also provides a connector assembly, comprising a connection socket and a connector. The connection socket is plugged into the connector to achieve electrical connection.

[0006] The present application also provides a battery device, including a battery cell, a circuit board and a connector assembly, wherein the circuit board is electrically connected to the battery cell, a conductive contact plate is provided on the circuit board, and a third conductive terminal of the connecting seat is connected to the conductive contact plate.

[0007] The connector of the present invention can be directly plugged into the connection seat on the circuit board by providing the first plug-in portion and the second plug-in portion at both ends of the first conductive terminal. Compared with the solution in which the plug-in portion is provided at one end of the conductive terminal, the welding cup is provided at the other end of the conductive terminal, one end of the wire is welded to the welding cup, and the other end of the wire is electrically connected to the circuit board, the connector of the present invention can omit the wire, has a simple structure, and is small in size. When the connector is used in a battery device, it occupies less space in the battery device. At the same time, when the connector needs to be repaired, the connector can be unplugged for repair without interference from the wire, and the repair is more convenient.
