Abstract
The utility model discloses an improved structure of a rotary arm for a vacuum contactor. One side of one end of the rotary arm is connected with a transmission shaft, while the identical side of the other end of the rotary arm is pressed against a spring pipe. The rotary arm is of a plate-shaped structure made of stainless steel materials, and the surface of the rotary arm is coated with a nonsaturated resin layer. The other end of the rotary arm is elastically pressed against one side of the spring pipe to form a friction surface. The friction surface is embedded with a metal pad. The improved structure of the rotary arm for the vacuum contactor is made of the stainless steel materials, thereby being sufficient in strength; the peripheral surface of the improved structure is further coated with the nonsaturated resin layer, thereby achieving a good insulating property; and simultaneously, the friction surface of the rotary arm is also embedded with the metal pad having an arc surface, thereby improving wear resistance.
Description
Technical field
The utility model relates to vacuum contactor, relates in particular to the pivoted arm structure-improved that a kind of vacuum contactor is used.
Background technology
Existing contactor pivoted arm structure is two kinds:
1, the structure that adopts full unsaturated-resin compression to form, shortcoming is as follows:
(1) strength of materials adds poorly, will meet the demands with more material under required structural strength;
(2) coefficient of friction is big, and is not wear-resisting, can't use in friction means.
2, adopt all-metal construction to utilize machine work to form, shortcoming is as follows:
(1) long processing time, precision height;
(2) being used for structure needs the increase insulator to come electrified body is isolated.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of vacuum contactor pivoted arm structure-improved, this vacuum contactor is poor with the structural strength that the pivoted arm structure-improved has solved pivoted arm, coefficient of friction greatly, the not wear-resisting and baroque problem of insulation property difference, realized the high strength of pivoted arm, high insulation, anti abrasive performance.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of vacuum contactor pivoted arm structure-improved, one side of described pivoted arm one end connects rotation axis, the same side elasticity of the described pivoted arm other end compresses bourdon tube, described pivoted arm is the platy structure that sheet metal is made, described pivoted arm surface-coated forms the unsaturated-resin layer, the side that described pivoted arm other end elasticity compresses bourdon tube forms rubbing surface, is inlaid with metallic gasket on the described rubbing surface.
As further improvement of the utility model, described unsaturated-resin layer is coated in the surface of the described pivoted arm other end.
As further improvement of the utility model, described metallic gasket is arc surface shape, and its protrusion direction is towards bourdon tube.
As further improvement of the utility model, described pivoted arm has two relative edges that extend from pivoted arm one end to the pivoted arm other end, described two relative edges extend side to the same side perpendicular to platy structure, and the height of described side reduces from pivoted arm one end to the pivoted arm other end gradually.
As further improvement of the utility model, described sheet metal is stainless steel material.
The beneficial effects of the utility model are: vacuum contactor of the present utility model adopts stainless steel material to make with the pivoted arm structure-improved, have enough intensity, on its surrounded surface, also be coated with the unsaturated-resin layer, realize the good insulation performance performance, simultaneously, on the rubbing surface of pivoted arm, also be inlaid with the metallic gasket of arc surface, improved resistance to wear.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is profile of the present utility model;
Fig. 3 is whole assembling schematic diagram of the present utility model.
Embodiment
Embodiment: a kind of vacuum contactor pivoted arm structure-improved as shown in Figure 1, one side of described pivoted arm 1 one ends connects rotation axis 4, the same side elasticity of the described pivoted arm other end compresses bourdon tube 5, described pivoted arm is the platy structure that sheet metal is made, described pivoted arm surface-coated forms unsaturated-resin layer 2, the side that described pivoted arm other end elasticity compresses bourdon tube forms rubbing surface, is inlaid with metallic gasket 3 on the described rubbing surface.
Preferable, described unsaturated-resin layer is coated in the surface of the described pivoted arm other end, and unsaturated-resin is coated in the pivoted arm surface, can obtain higher dielectric strength, and unsaturated-resin bears in this structure is not have torsion by material pressure.
Preferable, described metallic gasket is arc surface shape, and its protrusion direction is towards bourdon tube, and inlaying an arc surface metallic gasket at the rubbing surface place can increase anti-wear performance, reduces coefficient of friction.
Preferable, described pivoted arm has two relative edges that extend from pivoted arm one end to the pivoted arm other end, and described two relative edges extend side to the same side perpendicular to platy structure, and the height of described side reduces from pivoted arm one end to the pivoted arm other end gradually.
Preferable, described sheet metal is stainless steel material, making pivoted arm with stainless steel material can have enough intensity, and quality simple in structure is less.
