Abstract
The invention discloses a kind of vacuum contactor pivoted arm structure-improved, the side of described pivoted arm one end connects rotary shaft, the same side elasticity of the described pivoted arm other end compresses bourdon tube, described pivoted arm is the platy structure that stainless steel material is made, described pivoted arm surface-coated forms unsaturated-resin layer, described pivoted arm other end elasticity compresses the side of bourdon tube and forms rubbing surface, and described rubbing surface is inlaid with metallic gasket.The vacuum contactor pivoted arm structure-improved of the present invention uses stainless steel material to make, and has enough intensity, is also coated with unsaturated-resin layer on its surrounded surface, realize good insulating properties, meanwhile, the rubbing surface of pivoted arm is also inlaid with the metallic gasket of arc surface, improves wearability.
Description
Technical field
The present invention relates to vacuum contactor, particularly relate to the pivoted arm structure-improved of a kind of vacuum contactor
。
Background technology
Existing catalyst pivoted arm structure is two kinds:
1, using the structure that full unsaturated-resin compresses, shortcoming is as follows:
(1) strength of materials adds difference, meets requirement with more material under required structural strength；
(2) coefficient of friction is big, the most wear-resisting, it is impossible to use in friction means.
2, using all-metal construction to utilize to be machined into, shortcoming is as follows:
(1) long processing time, precision height；
(2) in structure, need to increase insulator electrical body is isolated.
Summary of the invention
In order to overcome drawbacks described above, the invention provides a kind of vacuum contactor pivoted arm structure-improved,
The structural strength that this vacuum contactor pivoted arm structure-improved solves pivoted arm is poor, coefficient of friction is big
, the most wear-resisting and poor baroque problem of insulating properties, it is achieved that the high intensity of pivoted arm, high absolutely
Edge, anti abrasive performance.
The present invention is to solve that its technical problem be the technical scheme is that
A kind of vacuum contactor pivoted arm structure-improved, the side of described pivoted arm one end connects rotary shaft,
The same side elasticity of the described pivoted arm other end compresses bourdon tube, described turn
Arm is the platy structure that sheet metal is made, and described pivoted arm surface-coated forms unsaturated-resin layer
, described pivoted arm other end elasticity compresses the side of bourdon tube and forms rubbing surface, on described rubbing surface
It is inlaid with metallic gasket.
As a further improvement on the present invention, described unsaturated-resin layer is coated in the described pivoted arm other end
Surface.
As a further improvement on the present invention, described metallic gasket is arc surface shape, its protrusion direction court
To bourdon tube.
As a further improvement on the present invention, described pivoted arm has and prolongs to the pivoted arm other end from pivoted arm one end
Two relative edges stretched, described two relative edges are perpendicular to platy structure to the same side and extend side
Limit, the height of described side gradually reduces from pivoted arm one end to the pivoted arm other end.
As a further improvement on the present invention, described sheet metal is stainless steel material.
The invention has the beneficial effects as follows: the vacuum contactor pivoted arm structure-improved of the present invention uses stainless
Steel material is made, and has enough intensity, is also coated with unsaturated-resin on its surrounded surface
Layer, it is achieved good insulating properties, meanwhile, is also inlaid with arc surface on the rubbing surface of pivoted arm
Metallic gasket, improve wearability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the profile of the present invention；
Fig. 3 is the overall assembling schematic diagram of the present invention.
Detailed description of the invention
Embodiment: a kind of vacuum contactor pivoted arm structure-improved as shown in Figure 1, described pivoted arm 1 one
The side of end connects rotary shaft 4, the described pivoted arm other end same
Side elasticity compresses bourdon tube 5, and described pivoted arm is the platy structure that sheet metal is made, described pivoted arm
Surface-coated forms unsaturated-resin layer 2, and described pivoted arm other end elasticity compresses the side of bourdon tube
Form rubbing surface, described rubbing surface is inlaid with metallic gasket 3.
It is also preferred that the left described unsaturated-resin layer is coated in the surface of the described pivoted arm other end, by unsaturation
Resin is coated in pivoted arm surface, can obtain higher dielectric strength, and unsaturated in this structure
Resin born for material pressure, there is not torsion.
It is also preferred that the left described metallic gasket is arc surface shape, its protrusion direction is towards bourdon tube, in friction
Inlay an arc surface metallic gasket at face and can increase anti-wear performance, reduce coefficient of friction.
It is also preferred that the left described pivoted arm has two relative edges extended from pivoted arm one end to the pivoted arm other end,
Described two relative edges are perpendicular to platy structure and extend side, the height of described side to the same side
Degree gradually reduces from pivoted arm one end to the pivoted arm other end.
It is also preferred that the left described sheet metal is stainless steel material, making pivoted arm with stainless steel material can have foot
Enough intensity, and simple in construction quality is less.
