Among the figure: 1 outer box; 11 shell chambeies; 111 chutes; 112 retaining walls; 12 tapping screw thread holes; 2 sensitive switches; 3 end caps; 31 shell chambeies; 32 location holes; 33 holes; 4 driving members; 41 slip end faces; 42 working faces; 43 boss; 44 holes.
Embodiment
The utility model is a kind of auxiliary switch of circuit breaker, comprising: the outer box of a square cavity shape, connect an end cap on this outer box, and a breach is arranged on this end cap; A T font driving member, its upper end is arranged in the shell chamber of end cap, and stretch out outside the shell chamber lower end, and this driving member can move in the shell chamber; At least one sensitive switch places the driving member below, places on the bottom in shell chamber, and the contact of sensitive switch is subjected to end motion on the driving member and moves; Connect extension spring on this driving member, the other end of this extension spring is connected with outer box or end cap.
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, be provided with three sensitive switches 2 in the shell chamber 11 of outer box 1, the end cap 3 that cooperates with outer box 1 is locked on the outer box 1 by location hole 32 and the tapping screw thread hole 12 on the housing (also can adopt the inserts screw) for outer box 1 location.Driving member 4 is arranged in the shell chamber 31 of end cap 3, is provided with chute 111 in the outer box 1, and an end face 41 of driving member 4 is plugged in the chute 111 of outer box 1, can move up and down along chute 111.Driving member 4 is provided with the working face 42 of three projectioies, each working face 42 has the inclined-plane and directly over sensitive switch 2, be provided with the retaining wall 112 of location sensitive switch 2 in the outer box 1, three sensitive switches 2 are arranged in the outer box 1, dividing wall 112 is isolated from each other sensitive switch, and dividing wall 112 also limits the displacement of sensitive switch all directions simultaneously.Extension spring 5 one ends hang on the hole 44 on the driving member 4, and the other end hangs in the hole 33 on the end cap 3.
As shown in Figure 2, during boss 43 on external force pulling driving member 4, driving member 4 moves down in chute 111, and working face 42 triggers sensitive switches 2.After external force removed, under the effect of spring 5, driving member 4 returned to initial position.
