Embodiment
Now will be in detail with reference to the preferred embodiments of the present invention, the example of these embodiment shown in the drawings.
Hereinafter, the movable contact that is used for circuit breaker according to of the present invention is described with reference to the accompanying drawings in further detail.
Fig. 1 is an end view, has shown the part of application according to the circuit breaker of the movable contact of the first embodiment of the present invention; Fig. 2 is a perspective view, has shown the movable contact that is used for circuit breaker according to first embodiment of the invention; And Fig. 3 is a perspective view, has shown the integrated side plate of axle according to the movable contact that is used for circuit breaker of first embodiment of the invention;
As shown in the figure, the movable contact D that is used for circuit breaker comprises: the housing 10 with definite shape; A plurality of joints 20, these joints are connected in a side of housing 10 with predetermined interval; With the side plate 40 of integrated axle, side plate 40 has certain area, and has from the one side with the outstanding axial region 41 of certain-length, and side plate 40 is connected in two side surfaces of housing 10, thereby covers joint 20.
Load-side binding post 60 is connected in the outlet side fixed contact C2 of circuit breaker fixed contact C.Joint 20 and load-side binding post 60 interconnect by the lead (not shown).
Load-side binding post 60 is connected in the bottom 51 of carriage 50 by bolt 61.
The axial region 41 of the side plate 40 of integrated axle rotatably is inserted in the slot 53.
Be formed with through hole in the axial region 41 of the side plate 40 of integrated axle.Preferably, axial region 41 has certain thickness annular section.
The side plate 40 of integrated axle comprises: the base portion 42 with certain thickness and area; Be formed on a plurality of conjugate foramens 43 of base portion 42 with penetrating; With the axial region 41 that extends with certain-length from the bottom of base portion 42.
As shown in Figure 4, through hole 44 is formed in the axial region 41 with penetrating.Preferably, through hole 44 forms and has crooked edge.
Preferably, the thickness that has of axial region 41 is less than the thickness of base portion 42.
The axial region 41 of the side plate 40 of integrated axle forms by the part of outstanding base portion 42.More specifically, as shown in Figure 5, the part of base portion 42 is stamped into outstanding for becoming hemisphere.Then, the mid portion of ledge is by punching, thus the formation through hole.Then, ledge is pushed away, thereby forms with predetermined outer diameter and the outstanding axial region 41 of length.
The side plate 40 of integrated axle is connected in the both sides of housing 10 respectively by bolt 11.Bolt 11 inserts respectively in the conjugate foramen 43, thereby is connected in housing 10.The axial region 41 of the side plate 40 of integrated herein, axle is outwards arranged.
