Description

Spring piece type wiring terminal

Technical Field

The utility model relates to a shell fragment formula binding post.

Background

Traditional circuit breaker binding post inserts the wire in the wiring hole, operates fastening screw again for the preforming of fastening screw rear end compresses tightly to the wire, and the defect of this kind of mode of connection lies in: because the operation force direction of the fastening screw is vertical to the insertion direction of the lead, the operation is complicated, and if the installation space of the circuit breaker is limited, the wiring fastening operation is inconvenient.

Disclosure of Invention

In view of this, the utility model aims at providing a convenient operation, need not screw-thread fastening, the direction of operation is the same with the direction of insertion of wire, the lower shell fragment formula binding post of requirement to installation space.

In order to realize above mesh, the utility model discloses a such shell fragment formula binding post, including lug, shell fragment and wiring board, the lug intermediate position be equipped with the baffle, the baffle separate into two wiring rooms around with the lug, two wiring rooms are located around, the left surface of lug on be equipped with a set of trompil separately, the trompil include wiring hole and preforming hole, the wiring room in be equipped with the fulcrum, the shell fragment including integrated into one piece's armful line portion in order, bulldoze portion, flexion and supporting part, the wire can pass the wiring hole reachd armful line portion, armful line portion be close to global of wiring board, bulldoze the position and the preforming hole adaptation of portion, the fulcrum is walked around to the flexion, the supporting part support and press in the inner wall of wiring room. Compared with the prior art, the invention has the beneficial technical effects that: through the setting of above structure, when needs wiring, only need insert the wiring hole with the wire, insert the clamp plate hole and act on the portion of bulldozing with operating tool, form the window between shell fragment and the connecting plate this moment, the wire of being convenient for passes through the window, and the operating tool is withdrawn from this moment, embraces line portion and connecting plate and embraces the wire tightly, the utility model has the characteristics of convenient operation, need not that the direction of insertion of screw-thread tightening, operation direction and wire is the same, and is lower to installation space's requirement.

Particularly, the wiring holes and the pressing sheet holes of the two wiring chambers are arranged in a crossed and opposite angle mode, the supporting points of the two wiring chambers are arranged in a staggered mode, and the opening directions of the elastic sheets of the two wiring chambers are opposite. Through the arrangement of the structure, the wiring boards of the two wiring chambers can be staggered up and down, and the electrical insulation distance between the two wiring boards is ensured.

Particularly, the supporting part is provided with a square hole, the shape of the wiring board is adapted to the inner wall of the wiring chamber, and one end of the wiring board penetrates through the square hole in the elastic sheet and extends out of the wiring chamber. Through the arrangement of the structure, the connection plate can be conveniently fixed with the internal electric connection position of the circuit breaker.

Particularly, the wire holding part of the elastic sheet is of a double-bending structure, one end of the wire holding part close to the pushing part is bent in a direction deviating from the pushing direction, and the tail end of the wire holding part is bent in a direction converging and crossing with the wiring board. Through the setting of above structure, not only increased the motion angle of shell fragment, increaseed the wiring window, moreover, can also strengthen the intensity of shell fragment, even the wire of heavy current specification is connected, also can guarantee the power of holding tightly of shell fragment. In addition, the wiring board and the elastic sheet jointly hold the wire tightly, the inner wall of the wiring block is subjected to small pressure, and the wiring block is not deformed even if a product is heated due to electrification.
