Description
Technical field
The utility model relates to a kind of contactor, particularly relates to the contactor that has independent nut in a kind of terminals seed cell.
Background technology
At present, the contactor of prior art generally is made up of base, an insulation body and an overhead guard that is used for installing device, and wherein, the insulation body is contained in the upper end of base, and overhead guard is connected in the upper end of the insulation body.Be provided with several terminals seed cells in this insulation body, and the screw assemblies of contact plate, band watt pad is housed in the terminals seed cell.The structure of this contact plate sees also shown in Figure 1, this contact plate 1 ' be provided with the contact to match with the screw of locking outer lead with screw assemblies with being used for.Because the material of copper is softer, make that the moment of torsion that contact plate 1 ' screw of self can bear is less, therefore, when the user guarantees that lead connects reliable more and need apply bigger moment of torsion and lock lead the time, sliding dental phenomenon takes place easily, and whole contactor can not be used.This will cause a large amount of wastes of precious metals such as copper, silver.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, the contactor that has independent nut in a kind of terminals seed cell is provided, it improves the structure of the contact plate of contactor, and design one and independently and by the nut that the rigidity material constitutes match with contact plate, make the screw thread in the nut be not easy to take place the phenomenon of sliding tooth.
The technical scheme that its technical problem that solves the utility model adopts is: have the contactor of independent nut in a kind of terminals seed cell, comprise a base that is used for installing device, an insulation body and and an overhead guard; The insulation body is contained in the upper end of base, and overhead guard is connected in the upper end of the insulation body; Be provided with some terminals seed cell in this insulation body; The screw assemblies of contact plate, band watt pad is housed in the terminals seed cell; Also comprise a nut; Be provided with a through hole that can allow the double-screw bolt of screw assemblies pass in this contact plate; The bottom of terminals seed cell is provided with a draw-in groove that is used for the described nut of setting-in; This nut is provided with the screwed hole that the double-screw bolt with described screw assemblies is complementary; Contact plate is contained in the upper end of nut, and the through hole of contact plate is concentric with the screwed hole of nut; The double-screw bolt of described screw assemblies passes behind the through hole of contact plate and to spin mutually with the screwed hole of nut and be locked in the bottom of terminals seed cell.
Described nut be shaped as non-circular structure, described draw-in groove is made as the structure that the shape with nut is complementary.
Described nut is made of the rigidity material.
The front end side wall of described contact plate outwards is provided with an epitaxy part that is down T-Type structure, and the top of this outer portion is bending structure, and is fixed in the front end side wall of contact plate; The front end cell wall of described draw-in groove is provided with one and is used for first breach that the bending structure of described outer portion is stepped down.
The beneficial effects of the utility model are, because the nut to contact plate designs separately, and make it to constitute by the rigidity material, when making this independently nut matching with screw, be not easy to make the screw thread of nut that the phenomenon of sliding tooth takes place because of the moment of torsion of turn screw assemblies is excessive; Because shape that will this independent nut is made as the structure of non-fillet, and correspondingly, in the terminals seed cell, be provided with a draw-in groove that is used for this independent nut of setting-in, make this independent nut rotation can not take place; Owing to be provided with a breach, make the front end cell wall of this draw-in groove to dodge, so that contact plate can be connected in the terminals seed cell securely to the bending structure of the outer portion of contact plate at the front end cell wall place of draw-in groove.Obviously, the design of independent nut of the present utility model has simple in structure, outstanding effect characteristics.
Below in conjunction with drawings and Examples the utility model is described in further detail; But the contactor that has independent nut in a kind of terminals of the present utility model seed cell is not limited to embodiment.
Description of drawings
Fig. 1 is the structural representation of the contact plate of prior art;
Fig. 2 is an exploded perspective view of the present utility model;
Fig. 3 is the structural representation of the insulation body of the present utility model.
Embodiment
Embodiment sees also Fig. 2, shown in Figure 3, has the contactor of independent nut in a kind of terminals of the present utility model seed cell, comprises that one is used for base 1, the insulation body 2 and an overhead guard 3 of installing device; The insulation body 2 is contained in the upper end of base 1, and overhead guard 3 is connected in the upper end of the insulation body 2; Be provided with several terminals seed cells in this insulation body 2, and contact plate 21 is housed in the terminals seed cell, has watt the screw assemblies 22 and the nut 24 of pad 23; This watt pad 23 rotating double-screw bolt tops that are connected to screw assemblies 22; Contact plate 21 is contained in the upper end of nut 24; Be provided with a through hole 211 that the double-screw bolt of screw assemblies 22 is passed in this contact plate 21; Be provided with in the nut 24 one with this through hole 211 screwed hole 241 concentric and that be complementary with the double-screw bolt of screw assemblies 22; The bottom of terminals seed cell is corresponding to be provided with a draw-in groove 25 that is used for this nut 24 of setting-in; Through hole 211 back that the double-screw bolt of described screw assemblies 22 passes contact plate 21 spins mutually with the screwed hole 241 of nut 24 and is locked in the bottom face of terminals seed cell.
Wherein,
The front end side wall of contact plate 21 outwards is provided with an epitaxy part 212 that is down T-Type structure, and the top of this outer portion 212 is bending structure, and is fixed in the front end side wall of contact plate 21; The front end cell wall of described draw-in groove 25 is provided with one and is used for breach 251 that the bending structure of described outer portion 212 is stepped down.
The contactor that has independent nut in a kind of terminals of the present utility model seed cell, compared with prior art, because its contact plate 21 is made as two independent structures with nut 24, and nut 24 is made of the rigidity material, make when the bigger moment of torsion turn screw assemblies 22 of usefulness, be not easy to make screw thread in the screwed hole 241 of nut 24 to deform and produce the phenomenon of sliding tooth.In addition, the shape of nut 24 is made as non-circular structure, and correspondingly be provided with the draw-in groove 25 that is used for this nut 24 of setting-in in the bottom of terminals seed cell, make that nut 24 embeds these draw-in grooves 25 after, can not take place from then make screwed hole 241 mismatches of screw assemblies 22 and nut 24.Moreover, because the front end cell wall of draw-in groove 25 has a breach 251, make the front end cell wall of this draw-in groove 25 to dodge, so that contact plate 21 can be connected in the terminals seed cell securely to the bending structure of the outer portion 212 of contact plate 21.
The foregoing description only is used for further specifying the contactor that has independent nut in a kind of terminals of the present utility model seed cell; but the utility model is not limited to embodiment; every foundation technical spirit of the present utility model all falls in the protection range of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
