Description
Technical Field
The utility model belongs to the technical field of transfer switches, and particularly relates to a transfer switch.
Background
The change-over switch has wide and various application in the industrial and household fields, realizes the switching of a load circuit between a main power supply and a standby power supply in a low-voltage distribution circuit, and ensures the continuity of power supply. Common change-over switches adopt operating mechanism to drive the circuit breakers of piecing together in its both sides and realize the switching function, and other change-over switches then use interlocking mechanism to connect the circuit breakers of both sides and realize switching requirement.
The existing change-over switch is generally provided with a spring piece at a wiring terminal, an opening is pressed below a screw, the spring piece is easy to deform in the crimping process, so that the screw torque force is too small, the change-over switch is poor in contact, and the traditional spring piece structure is easy to cause the loose line between a static contact plate and a terminal, so that the problem of poor contact is also caused. It is therefore necessary to relate to a change-over switch.
Disclosure of Invention
According to the change-over switch, the static contact plate is fixed on the shell, the lead is arranged between the static contact plate and the wire frame, the clamping wire is more fastened, the wire frame is driven to act by adjusting the wire screw, the torsion of the wire screw is effectively improved, and the connection is more stable.
In order to solve the problems, the utility model adopts the following technical scheme.
A change-over switch comprises a shell, wherein a locking part is integrally formed in the shell, a static contact plate is clamped by the locking part, one side of the static contact plate is inserted into a wire frame positioned on two sides of the shell, the static contact plate is bent upwards towards the side of the wire frame to form a bending part, and the bending part is abutted to the side wall of the wire frame.
Preferably, a linkage assembly is further arranged in the shell, the linkage assembly comprises a connecting piece, an upper movable contact plate and a lower movable contact plate are respectively arranged on the connecting piece, and a spring is arranged between the shell and the connecting piece.
Preferably, the upper movable contact plate and the lower movable contact plate are both provided with movable contacts.
Preferably, a fixed contact is arranged on one side of the fixed contact plate, which is far away from the wire frame, and corresponds to the movable contact.
Preferably, the static touch plate and the wire frame are arranged in a vertically staggered manner.
Advantageous effects
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, the static contact plate is fixed on the shell, the lead is arranged between the static contact plate and the wire frame, the wire clamping is more fastened, the wire frame is driven to act by adjusting the wire connecting screw, the torsion of the wire connecting screw is effectively improved, and the connection is more stable.
