Abstract
The utility model relates to the assembly structure of a kind of thermal relay and contactor.Mainly solve certain angle can appear in existing thermal relay rotary motion around two product contact points, the cell wall distance of rotating aft hook and contactor increases, and causes linking up with the cell wall pasting not close contact, thus the problem that wire is easily loosened.Comprise contactor case, thermal relay shell, described contactor case is provided with draw-in groove, and described thermal relay shell is provided with hook, and the both sides of described hook are provided with the boss of outwardly convex, described hook inserts in draw-in groove, the outer surface of described boss and the contactor surface at draw-in groove place inconsistent.Hook both sides are made with two projections, and one is prevent thermal relay product axial deflection in use procedure, threatens to the compression of wire; Two is avoid hook to rupture with contact when another wall of tank extrudes mutually, the intensity that increase is linked up with.
Description
Technical field
The utility model relates to a kind of thermal relay, refers in particular to the assembly structure of a kind of thermal relay and contactor.
Background technology
Coordinating of contactor and thermal relay is fixedly ensured by the assembly structure of thermal relay and contactor and wire, when existing thermal relay coordinates with contactor, owing to there is certain gap between two product the latter halfs, make thermal relay can occur the rotary motion of certain angle around two product contact points, the cell wall distance of rotating aft hook and contactor increases, cause linking up with the cell wall pasting not close contact, contact fixation between contactor and thermal relay is mainly through wire tensioning, thermal relay product is because self gravitation effect meeting is to wire effect one opposite force, wire is caused easily to fluff dynamic.
Utility model content
In order to overcome shortcoming and the weak point of background technology, the utility model provides the assembly structure of a kind of thermal relay and contactor, solve certain angle can appear in existing thermal relay rotary motion around two product contact points, the cell wall distance of rotating aft hook and contactor increases, cause linking up with the cell wall pasting not close contact, thus the problem that wire is easily loosened.
The technical solution of the utility model is: the assembly structure of a kind of thermal relay and contactor, comprise contactor case, thermal relay shell, described contactor case is provided with draw-in groove, described thermal relay shell is provided with hook, the both sides of described hook are provided with the boss of outwardly convex, described hook inserts in draw-in groove, the outer surface of described boss and the contactor surface at draw-in groove place inconsistent.
Described boss is integrally formed by connecting with hook.
Described boss is symmetrical along the center line of hook.
Described boss is square, triangle, semicircle or half elliptic.
Described boss is connected with thermal relay shell one.
the utility model has following beneficial effect:hook both sides are made with two projections, and one is prevent thermal relay product axial deflection in use procedure, threatens to the compression of wire; Two is avoid hook to rupture with contact when another wall of tank extrudes mutually, the intensity that increase is linked up with.
Accompanying drawing explanation
Fig. 1 is exploded view of the present utility model.
Fig. 2 is another angle decomposition figure of the present utility model.
Fig. 3 is internal structure schematic diagram of the present utility model.
Fig. 4 is the schematic enlarged-scale view at A place in the utility model Fig. 3.
In figure, contactor case 1, thermal relay shell 2, draw-in groove 3, hook 4, boss 5, contactor surface 6.
Embodiment
Be described further for embodiment of the present utility model below:
As shown in the figure, the assembly structure of a kind of thermal relay and contactor, comprise contactor case 1, thermal relay shell 2, described contactor case 1 is provided with draw-in groove 3, described thermal relay shell 2 is provided with hook 4, the both sides of described hook 4 are provided with the boss 5 of outwardly convex, and described hook 4 inserts in draw-in groove 3, and the contactor surface 6 at the outer surface of described boss 5 and draw-in groove 3 place is inconsistent.In the both sides of hook, 2 boss are set, the thickness of boss and width are arranged according to the size of draw-in groove, during installation, hook is pushed in draw-in groove, and make the contactor surface contacting at draw-in groove opening part on the surface of boss, according to such scheme, hook both sides are made with two projections, one is prevent thermal relay product axial deflection in use procedure, threatens to the compression of wire; Two is avoid hook to rupture with contact when another wall of tank extrudes mutually, the intensity that increase is linked up with.
In the utility model, described boss 5 is integrally formed by connecting with hook 4.Described boss 5 adopts integrated injection molding to form with hook 4, is convenient to processing, and improves the intensity of hook further.
In the utility model, described boss 5 is symmetrical along the center line of hook 4.Boss 5 structure of both sides is identical, is symmetrically distributed in the both sides of hook, ensures location, both sides uniformity, stability when assembling is effectively improved.
In the utility model, described boss 5 is square, triangle, semicircle or half elliptic.The formation of boss can be carried out selecting different shapes as required.
In the utility model, described boss 5 is connected with thermal relay shell 2 one.The inner surface of boss 5 and thermal relay shell 2 are wholely set and form.Easy to process, intensity is high.
Embodiment should not be considered as the restriction to utility model, but any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
