Abstract
The invention 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 rotation shaft, and the same side of the other end of the rotary arm elastically presses against a spring pipe. The rotary arm is of a plate-shaped structure made of stainless steel material, and the surface of the rotary arm is coated with a non-saturated resin layer. The side, elastically pressing against the spring pipe, of the other end of the rotary arm forms 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 material and thus has sufficient strength; the peripheral surface of the improved structure is further coated with the non-saturated resin layer so that good insulating performance is achieved; and meanwhile, the friction surface of the rotary arm is embedded with the metal pad having an arc surface, which improves the wear resistance.
Description
Technical field
The present invention relates to vacuum contactor, relate 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, adopt full unsaturated-resin to compress the structure forming, shortcoming is as follows:
(1) strength of materials adds poorly, under required structural strength, meets the demands with more material;
(2) coefficient of friction is large, not wear-resisting, cannot use in friction means.
2, adopt all-metal construction to utilize machine work to form, shortcoming is as follows:
(1) long processing time, precision are high;
(2) needing to increase insulator for structure isolates electrified body.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of vacuum contactor pivoted arm structure-improved, structural strength that this vacuum contactor has solved pivoted arm with pivoted arm structure-improved is poor, coefficient of friction greatly, the not wear-resisting and poor baroque problem of insulation property, realized the high strength of pivoted arm, high insulation, anti abrasive performance.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of vacuum contactor pivoted arm structure-improved, the one side connection of rotating axle of described pivoted arm one end, 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 unsaturated-resin layer, the side that described pivoted arm other end elasticity compresses bourdon tube forms rubbing surface, on described rubbing surface, is inlaid with metallic gasket.
As a further improvement on the present invention, described unsaturated-resin layer is coated in the surface of the described pivoted arm other end.
As a further improvement on the present invention, described metallic gasket is arc surface shape, and its protrusion direction is towards bourdon tube.
As a further improvement on the present invention, described pivoted arm has two relative edges that extend to the pivoted arm other end from pivoted arm one 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 a further improvement on the present invention, described sheet metal is stainless steel material.
The invention has the beneficial effects as follows: vacuum contactor of the present invention pivoted arm structure-improved adopts stainless steel material to make, have enough intensity, on its surrounded surface, be also coated with unsaturated-resin layer, realize good insulation property, simultaneously, the metallic gasket that is also inlaid with arc surface on the rubbing surface of pivoted arm, has improved resistance to wear.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is profile of the present invention;
Fig. 3 is entirety assembling schematic diagram of the present invention.
Embodiment
Embodiment: a kind of vacuum contactor pivoted arm structure-improved as shown in Figure 1, the one side connection of rotating axle 4 of described pivoted arm 1 one end, 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 described rubbing surface.
Preferably, described unsaturated-resin layer is coated in the surface of the described pivoted arm other end, and unsaturated-resin is coated in to pivoted arm surface, can obtain higher dielectric strength, and in this structure, unsaturated-resin bears is material pressure, does not have torsion.
Preferably, described metallic gasket is arc surface shape, and its protrusion direction is towards bourdon tube, and inlaying an arc surface metallic gasket at rubbing surface place can increase anti-wear performance, reduces coefficient of friction.
Preferably, described pivoted arm has two relative edges that extend to the pivoted arm other end from pivoted arm one 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.
Preferably, described sheet metal is stainless steel material, and making pivoted arm with stainless steel material can have enough intensity, and quality simple in structure is less.
