Description
Technical field
The utility model relates to electromagnetic contactor technical field, especially a kind of structure of contact terminal of electromagnetic contactor.
Background technology
Contactor (Contactor) is a kind of is used for switching on and off continually at a distance the electrical equipment of AC-DC Circuit and large volume controlled electric current.Its basic functional principle is the electromagnetic mechanism by consisting of coil, static iron core and moving iron core (or claiming armature), converts electromagnetic energy to mechanical energy, drives the contact unit action of contactor.In existing contactor, contact unit consists of the main contact and the auxiliary contact that are contained in contactor housing conventionally, and wherein main contact is for break-make major loop.
In prior art, the structure of contact terminal of electromagnetic contactor, its main noddle on contactor surface is sphere or arc, in the process frequently switching on and off, between movable contact and fixed contact, electron repelling power causes that contact area diminishes, contact resistance becomes large, contact temperature rising, cause contactor noise to become large, overall performance declines, even overheated scaling loss.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of structure of contact terminal of electromagnetic contactor rational in infrastructure, thereby improves dependability, and the overall performance of electromagnetic contactor improves, and contact area is large, eliminates contact noise.
The technical scheme that the utility model adopts is as follows:
A structure of contact terminal for electromagnetic contactor, comprises framework, and described frame mid portion is provided with movable support, and described movable support middle part perforate, is fixed with moving contact platform in described hole, and Compress Spring is installed at the top that is positioned at moving contact platform; Bottom, described moving contact platform two ends is separately installed with upper contact position, and described upper contact is provided with a plurality of projections on position; Be positioned on the framework at movable support two ends and be connected with respectively fixed contact platform, on described fixed contact platform, lower contact position is installed, described lower contact is provided with a plurality of projections on position equally; Described upper contact position is relative with lower contact position installs, and described upper contact position is identical with boss number set on lower contact position.
Further improvement as technique scheme:
On described upper contact position and lower contact position, be respectively arranged with two projections.
On described upper contact position and lower contact position, be respectively arranged with three projections.
The U-shaped structure that described fixed contact platform is laterally placed.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to operate, by controlling the rise and fall of movable support, can complete easily quiet contact point with the contact of moving contact point with separated, position, contact adopts identical wavy shaped configuration, remains enough abundant contacts between the contact that contact-making surface is, contact area is large, effectively can remove the increase of contact noise or contact contact resistance, degradation deleterious effects under electric conductivity.The overall performance of electromagnetic contactor improves, and dependability is good.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the structure of contact terminal of the electromagnetic contactor of the present embodiment, comprises framework 1, framework 1 middle part is provided with movable support 4, movable support 4 middle part perforates, are fixed with moving contact platform 3 in hole, Compress Spring 2 is installed at the top that is positioned at moving contact platform 3; Moving contact platform 3 bottoms, two ends are separately installed with upper contact position 5, are provided with a plurality of projections on upper contact position 5; Be positioned on the framework 1 at movable support 4 two ends and be connected with respectively fixed contact platform 7, lower contact position 6 is installed on fixed contact platform 7, on lower contact position 6, be provided with equally a plurality of projections; Upper contact position 5 installation relative to lower contact position 6, upper contact position 5 is identical with boss number set on lower contact position 6.
On upper contact position 5 and lower contact position 6, be respectively arranged with two projections.
On upper contact position 5 and lower contact position 6, be respectively arranged with three projections.
The U-shaped structure that fixed contact platform 7 is laterally placed.
In actual use procedure, drive movable support 4 to move downward, when it moves downward, upper contact position 5 contacts with lower contact position 6, effect due to Compress Spring 2, Compress Spring 2 exerts pressure to fixed contact platform 7, makes upper contact position 5 be adjacent to lower contact position 6, makes to switch on after its contact.Due to protruding design, as shown in Figure 3, after upper contact position 5 contacts with lower contact position 6, produce two contacts wire 8.As shown in Figure 4, after upper contact position 5 contacts with lower contact position 6, produce three contacts wire 8.Contact area is large.
As shown in Figure 3 and Figure 4, the contact face of lower contact described in the utility model position 6 correspondences, can be smooth, can be also to have minute protrusions.
On the other hand, as shown in Figure 4, upper contact position 5 and lower contact position 6 salient point are separately mutually corresponding, and the boss of same number is in contact with one another.But the not corresponding situation about being in contact with one another of the boss that also has in some cases, upper contact position 5 and lower contact position 6.
Also have special circumstances, the contact site on above-mentioned upper contact position 5 and the contact-making surface at lower contact position 6 is mutually corresponding, forms concaveconvex shape bonded to each other.
Due to upper contact described in the utility model position 5 and the 6 several contacts site of formation, lower contact position.Contact area increases greatly.On a plurality of fulcrums, by electric current, the electric current flowing through on each fulcrum is reduced, electromagnetic repulsive force also reduces (electromagnetic repulsive force and electric current square be directly proportional) along with reducing of current flowing on a fulcrum.So the utility model can be removed the increase of contact noise or contact contact resistance, degradation deleterious effects under electric conductivity.The overall performance that is applicable to electromagnetic contactor can be improved.
A plurality of waveforms that convex to form that arrange on upper contact described in the utility model position 5 and lower contact position 6, it has not only increased contact area, has also played the effect of shunting, reduces electromagnetic repulsive force.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection range of the present utility model, can be done any type of modification.
