Abstract
A novel vacuum AC contactor mainly solves the problems that after being stretched and compressed many times, a reaction spring in a contactor is weakened in elasticity, and can not timely enable a contact to be disconnected, and contactor performance is seriously affected. The novel vacuum AC contactor is characterized in that an adjusting screw and a cushion sleeve are further arranged in a contactor body, one end of the reaction spring is connected with an L-shaped crank arm, and the other end of the reaction spring is connected with the cushion sleeve which is connected with a screw, a part of the screw is exposed of the contactor body, and a handheld portion is connected with the exposed part of the screw. The novel vacuum AC contactor can control stretching amount of the spring through the adjusting screw, and greatly improves stability and service life of a mechanism.
Description
Technical field
The utility model relates to a kind of vacuum A.C. contactor, is specifically related to a kind of novel evacuated A.C. contactor.
Background technology
The eighties of last century the nineties middle and later periods, the vacuum A.C. contactor begins to enter industries such as power plant, metallurgy, chemical industry.And before this, these places are being controlled by circuit breaker.That is to say that we are drawing little mill with cart before this.And but the mechanical endurance of vacuum contactor is long and the characteristics of frequent operation, is again that circuit breaker is incomparable.
Be provided with reaction spring in the existing vacuum A.C. contactor, be mainly used in discharging armature, the contact is disconnected.This reaction spring is by after the Compression and Expansion repeatedly, and elasticity weakens, and timely break contact has a strong impact on the performance of contactor.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel evacuated A.C. contactor, has mainly solved in the contactor reaction spring by after the Compression and Expansion repeatedly, and elasticity weakens, and timely break contact has a strong impact on the problem of contactor performance.
The technical scheme that the utility model adopts is: a kind of novel evacuated A.C. contactor, comprise the contactor body, reaction spring, be provided with L type connecting lever in the described contactor body, also be provided with adjustment screw and cushion cover in the described contactor body, described reaction spring one end is connected with L type connecting lever, one end is connected with cushion cover, described cushion cover is connected with screw, and described bolt portion is exposed the contactor body, and is connected with the grip part on the screw of described exposed portions serve.
Described L type connecting lever is made up of connecting portion and driving section, and described connecting portion is connected by first bearing pin with the driving section, and described driving section is connected with the contactor body by second bearing pin.
The beneficial effects of the utility model are: can improve mechanism stability and useful life greatly by regulating the stroke that adjustment screw is come control spring.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-contactor body among the figure, 2-reaction spring, 3-L type connecting lever, 31-connecting portion, 32-driving section, 4-adjustment screw, 5-cushion cover, 6-grip part, 7-first bearing pin, 8-second bearing pin.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of novel evacuated A.C. contactor, comprise contactor body 1, reaction spring 2 is provided with L type connecting lever 3 in the described contactor body 1, also be provided with adjustment screw 4 and cushion cover 5 in the described contactor body 1, described reaction spring 2 one ends are connected with L type connecting lever 3, and an end is connected with cushion cover 5, and described cushion cover 5 is connected with screw 4, described screw 4 parts are exposed contactor body 1, and are connected with grip part 6 on the screw 4 of described exposed portions serve.
Described L type connecting lever 3 is made up of connecting portion 31 and driving section 32, and described connecting portion 31 is connected by first bearing pin 7 with driving section 32, and described driving section 32 is connected with contactor body 1 by second bearing pin 8.When L type connecting lever 3 breaks down, can change parts separately, do not need integral replacing.
The concrete use of the utility model is as follows: after the long-term use of contactor, the elasticity of reaction spring 2 weakens, and the user can regulate adjustment screw 4 by rotation grip part 6, compression or stretching reaction spring 2, the sensitivity of maintaining body and stability.
The beneficial effect of utility model is: can improve mechanism stability and useful life greatly by regulating the stroke that adjustment screw is come control spring.
