Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted actuators, in particular to a wiring terminal structure. Background Art

[0002] With the development of the economy, the automobile industry has developed rapidly. In order to ensure the stable operation of the automobile powertrain, it is necessary to equip it with a complete actuator. Therefore, various actuators with motors are widely used in automobile powertrains, including hydraulic actuators, gear selection and shift actuators, brake assist, etc.

[0003] Most existing actuators use a controller to control the motor-driven execution structure. The controller is connected to the vehicle's upper control structure through a connector. The connection stability between the connector pins and the PCBA determines the working stability of the entire actuator. Traditional controllers and connectors use soldering and clamping processes to directly weld the connector pins and PCBA together. When the entire vehicle vibrates, the rigid connection can easily lead to weld breakage, resulting in poor contact and causing the actuator to malfunction. Therefore, improvement is necessary. Utility Model Content

[0005] The above-mentioned technical problem of the present invention is solved by the following technical solution: a terminal structure, including a circuit board, a plurality of wiring slots are provided on the circuit board, each of the wiring slots is provided with a terminal, the terminal is formed by stamping and winding a one-piece sheet, the joint of the terminal is not sealed, the terminal has a connector pin inserted therein, and the terminal includes a limit plate resting on the surface of the circuit board and a plug-in body extending to the bottom of the circuit board. The terminal of the present invention is formed by stamping and winding a one-piece metal sheet, and an assembly gap is reserved at the joint on one side, so that when the terminal is inserted into the circuit board, it can be better assembled, eliminate tolerances, and reduce production costs to a certain extent. After the terminal is inserted into the circuit board, it is welded and fixed, and finally the connector pin is inserted into the terminal.

[0006] Preferably, an assembly gap is reserved at the joint of the terminal block. The terminal block of the utility model is formed by stamping and winding an integral metal sheet, and an assembly gap is reserved at the joint on one side. When the terminal block is inserted into the circuit board, it can be better assembled, eliminate tolerances, reduce the dimensional accuracy of the terminal block, and reduce production costs to a certain extent.

[0007] Preferably, the top of the terminal block is integrally formed with an arc-shaped guide plate that opens to both sides. The arc-shaped guide plate and the terminal block are stamped and wound as a single piece, and the arc-shaped guide plate serves to guide the pins of the connector when inserting them, allowing for quick and accurate insertion of the connector.

[0008] Preferably, the plug body is integrally formed with a plurality of inward-bending spring pieces. The terminal block of the present invention clamps the pins with the plurality of inward-bending spring pieces, eliminating the need for welding and reducing process costs. In addition, the inward-bending spring pieces can ensure that the terminal block is always clamped during vehicle operation, ensuring connection stability. At the same time, the elastic clamping of the terminal block can prevent contact instability during operation.

[0009] Preferably, the inward-bending spring piece and the connector pin are coaxially distributed. The inward-bending spring piece and the connector pin are vertically coaxially arranged to ensure that the connector pin is smoothly inserted and clamped by the inward-bending spring piece.
