Such isolator has that the clean and tidy nature of whole part is better, elastomeric element durable's advantage.
Description
Technical field
This utility model belongs to technical field of electricity, concretely relates to isolation switch.
Background technology
Isolation switch includes acting arm, mounting seat and static contact, acting arm is hinged in mounting seat, move acting arm to realize the contact of itself and static contact or separate, acting arm includes the side panel of both sides, there is screw on the side panels, by screw, two side panels are coupled together with screw, be locating part between two side panels；In prior art, spring is set between the outer end and side panel of screw, such acting arm has that whole parts cleaning is poor, spring easily tired, be easily damaged, long-time use also has acting arm and accommodates unstable shortcoming.
Summary of the invention
The shortcoming that the purpose of this utility model is aiming at prior art, it is provided that a kind of whole parts cleaning is better, a kind of isolation switch improving acting arm of elastomeric element long-lived isolation switch.
The technical solution of the utility model is achieved in that a kind of isolation switch improving acting arm, including acting arm, mounting seat and static contact, acting arm is hinged in mounting seat, acting arm includes the side panel of both sides, there is screw on the side panels, by screw, two side panels are coupled together with screw, be locating part between two side panels；It is characterized in that: described acting arm is provided with butterfly reed between the outer end and side panel of screw, described butterfly reed is the butterfly steel disc with interstitial hole.
Saying further, described butterfly reed has concave side and convex side, and it is a pair butterfly reed that the concave side of two butterfly reeds or convex side are oppositely arranged, and the butterfly reed installed between the outer end and side panel of screw is a pair butterfly reed or multipair butterfly reed.
The beneficial effects of the utility model are: such isolation switch has that whole parts cleaning is better, the long-lived advantage of elastomeric element；The butterfly reed installed between the outer end and side panel of screw is a pair butterfly reed or multipair butterfly reed, has the better advantage of elastic effect.

Wherein: 1, side panel 2, screw 3, locating part 4, butterfly reed 5, interstitial hole 6, concave side 7, convex side 8, acting arm 9, mounting seat 10, static contact.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As shown in Figure 1,2,3, 4, a kind of isolation switch improving acting arm, including acting arm 8, mounting seat 9 and static contact 10, acting arm 8 is hinged in mounting seat 9, acting arm 8 includes the side panel 1 of both sides, there is screw on the side panels, by screw, two side panels are coupled together with screw 2, be locating part 3 between two side panels；It is characterized in that: described acting arm 8 is provided with butterfly reed 4 between the outer end and side panel of screw 2, described butterfly reed is the butterfly steel disc with interstitial hole 5.
Described butterfly refer to butterfly reed mid portion and about part not in one plane, the middle concave of side goes down, around protrude, opposite side is contrary, just as the structure that plate processes.
This utility model takes butterfly reed, and it has good springiness, long-lived advantage.
Saying further, described butterfly reed has concave side 6 and convex side 7, and it is a pair butterfly reed that the concave side 6 of two butterfly reeds or convex side 7 are oppositely arranged, and the butterfly reed installed between the outer end and side panel of screw is a pair butterfly reed or multipair butterfly reed.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and change or the modification made all are encompassed in the scope of the claims of the present utility model.
