Preferably, the central angle of the fan-shaped notch is 60°-120°.

Preferably, the outer diameter of the wire is smaller than the radius of the fan-shaped notch.

Preferably, the shape of the end of the screw is arc, and the arc of the end of the screw is adapted to the shape of the wire on the contact surface.

Preferably, the diameter of the screw is not smaller than the diameter of the wire.

Preferably, there is no less than one fixing screw.

Preferably, there are two fixing holes, and there are also two fixing screws corresponding thereto, and the two fixing holes are respectively located at the upper part and the lower part of the terminal body.

The beneficial effects of the utility model:

The utility model improves the conductive performance of the connection part between the terminal and the wire, and the tensile strength of the connection between the wire and the terminal is improved, so that the connection between the terminal post and the wire is more firm, and effectively solves the looseness between the terminal and the wire And the virtual connection phenomenon, and then put an end to the high temperature burning of the terminal to destroy the fault.

A terminal that increases the contact area angle between conductive conductors. The design structure enhances the conductivity of the terminal and the conductivity of the connected wire. The main body part of the terminal block is used to connect the wires. The main axis of the binding post is provided with a slotted hole. The utility model sets the cross-section of the slot to be fan-shaped. Therefore, the slots for accommodating the wires are fan-shaped cylinder slots. After the wire is placed in the terminal slot, the two sides of the fan-shaped slot are in tangential contact with the cylindrical wire to complete the connection. At this time, the wire is fitted along the axis of the fan-shaped groove. When the screw is tightened, its bottom surface is in contact with the wire and the wire is pressed tightly to fix it in the terminal. The two fixing holes are respectively located at the upper part and the lower part of the terminal body, and the fixing wires are stronger, firmer and more reliable. The arc shape at the end of the screw is adapted to the shape of the wire on the contact surface, so that the contact surface is larger and the wire is fixed more stably.
