In figure, wire frame 1, conductive plate 2, the first brace 21, horizontal part 211, vertical portion 212, the second brace 22, screw 3, bimetal leaf 4, groove 5, V-shaped groove 6, arc striking piece 7.
Embodiment
For accompanying drawing, embodiment of the present utility model is described further below:
As shown in the figure, a kind of terminal structure of miniature circuit breaker, comprise wire frame 1, conductive plate 2 and screw 3, described conductive plate 2 is positioned at wire frame 1, described screw 3 matches with conductive plate 2 through wire frame 1, described conductive plate 2 comprises first brace 21 of " L " shape and the second brace 22 of bending shape, one end of described first brace 21 is positioned at wire frame 1, described screw 3 cooperatively interacts through wire frame 1 and the first brace 21, one end of described second brace 22 is used for being connected with bimetal leaf 4, the other end of described first brace 21 is connected with the other end one of the second brace 22.By adopting integral type to process conductive plate, when assembling, one end penetrates in wire frame, the other end and bimetal leaf and arc striking piece are integrally welded, convenient and simple for operation, according to such scheme, because the conductive plate of the terminal structure of this miniature circuit breaker adopts integral structure, there is the advantages such as easy to assembly, process stabilizing, wiring fastness are strong and temperature rise is low.
In the present embodiment, described conductive plate 2 is integrally formed by connecting by cold stamping by described first brace 21 and the second brace 22.Adopt cold stamping mode to improve conductive plate moulding, but also there is advantage easy to process.
In the present embodiment, described first brace 21 comprises horizontal part 211 and vertical portion 212, described horizontal part 211 is positioned at wire frame 1, it is outer and be connected with the second brace 22 that described vertical portion 212 is positioned at wire frame 1, the upper surface of described horizontal part 211 is provided with 2 parallel distributions and is the groove 5 of strip, described groove 5 and screw 3 frictional fit.By the horizontal part of conductive plate being arranged 2 grooves, thus forming frictional fit with screw, improving frictional force, improve the stability regulated.
In the present embodiment, the horizontal part both sides being positioned at the centre of 2 grooves 5 described in are provided with corresponding V-shaped groove 6.By increasing V-shaped groove again on the basis of groove, further can improve frictional force, ensureing stability during screw operation.
In the present embodiment, described conductive plate 2 is integrally welded by the bimetal leaf 4 of the second brace 22 and circuit breaker, arc striking piece 7.Conductive plate 2 and bimetal leaf 4, arc striking piece 7 all adopt one to weld, and connectivity robustness is high, easy to assembly, and wiring fastness is strong.
Embodiment should not be considered as the restriction to utility model, but anyly done based on spirit of the present utility model
Improvement, all should within protection range of the present utility model.
