The low-voltage circuit breaker is also called an automatic switch, and is an electric appliance which not only has the function of a manual switch, but also can automatically perform voltage loss, undervoltage, overload and short-circuit protection. It can be used to distribute electric energy, start asynchronous motor infrequently, protect power supply circuit and motor, and has been widely used.

The circuit breaker is used for connecting the main circuit and an external circuit. Generally, the wiring terminals are arranged to be connected with external leads, the wiring direction of the wiring operation of the conventional circuit breaker wiring terminals is perpendicular to the wiring direction, namely, the direction of external force used for the wiring operation is not in the same direction as the wiring direction of the leads, at least two directions of spaces are needed in the wiring process of the wiring terminals to operate, but some circuit breakers need to be installed in narrow spaces at present, only the wiring direction of the circuit breakers has a space for wiring operation, and the conventional wiring terminals cannot meet the wiring connection of the wiring terminals under the condition.

In order to solve the technical defect that the occupied space is large when the space in at least two directions is needed to be operated in the existing wiring process of the wiring terminal, one of the existing solutions is that the elastic sheet type connection mode is adopted when the electric connection with the smaller current specification is used, but the elastic sheet type wiring mode is used for connecting the lead with the large current specification, the rigidity of the required spring sheet is large, the deformation angle is large, the required operating force is large, and the operation difficulty is increased.

In order to achieve the technical purpose, the invention designs a composite wiring terminal, which is characterized in that: the wiring clamp comprises a wiring clamp, a spring piece, a rotating shaft, a first wiring board, a screw and a nut;

the spring piece is arranged on the rotating shaft in the jointing clamp and can rotate around the rotating shaft;

the first wiring board is arranged on one side of the top end of the wiring clamp;

a wiring space is reserved between the first wiring board and the elastic arm end on one side of the spring piece and is used for inserting an external lead;

the terminal is characterized in that a nut is arranged on the side of the bottom side of the jointing clamp, the nut is arranged on the jointing clamp, the screw penetrates through one end of the nut and can push the support arm end on the other side of the spring piece to enable the spring piece to rotate, and the spring arm end can compress an inserted external lead in the rotation process of the spring piece.

Preferably, the end of the screw contacting with the spring plate is a smooth surface without threads.

Preferably, the first wiring board is made of a conductive material.

Further, the wiring clamp can be formed by clamping the wiring board II and the wiring seat.

Further, the first wiring board and the wiring clamp are integrated.

Further, the nut and the jointing clamp are integrated.

Advantageous effects

The combined type wiring terminal provided by the invention adopts a mode of combining the screw and the spring piece, not only solves the problem that the wiring direction is not in the same direction, but also solves the technical problem that the operation force is large and the external wiring harness is difficult to insert through the transmission of the screw.
