Abstract
The utility model relates to a connector. The connector comprises a housing. A via is disposed in the middle of the housing. A diameter of the via is larger than a diameter of a wire. A head end of the housing is provided with external threads. An outer end of the via in the housing is in a cone shape. The connector also comprises a nut with a taper hole and a sealing retainer ring. An overall of the sealing retainer ring is in a hexagon shape. A dimension of a conical surface B on an upper end of the hexagon is matched with a dimension of a taper hole on an outer end of the housing. A dimension of a conical surface A on a lower end of the hexagon is matched with a dimension of a taper hole on the nut. The sealing retainer ring is provided with a hole inside, and a diameter of the hole is larger than an external diameter of the wire. The wire is inserted into the hole of the sealing retainer ring, and then the nut is screwed in the external threads of the housing. With the nut gradually screws tightly, the taper hole of the nut extrudes the sealing retainer ring to deform. The conical surface B of the sealing retainer ring extends upward under the action of the taper hole of the housing and joints with an outer surface of the wire, and the conical surface A extends downward and joints with the outer surface of the wire, thereby achieving sealing of the wire.
Description
Technical field
The utility model relates to a kind of electric component, is specifically related to a kind of connector.
Background technology
As everyone knows, communication cable in the colliery connects needs to use the intrinsic safety type connector, and it is little that it has a volume, in light weight, easy to connect, characteristics such as safe and reliable, mainly being applicable to has vibration, impact, trickle and coal dust is arranged and the occasion of property admixture of gas such as gas in the colliery.Existing intrinsic safety connector mainly is used in the O-ring seal that the outside diameter of cable is complementary and realizes sealing, during connection, need be with clamp nut on the stube cable lead string, and pad and sealing ring insert Connection Block respectively, therefore use loaded down with trivial details inconvenience.
Summary of the invention
The utility model provides a kind of mine intrinsic safety connector in order to overcome the deficiency of above technology.
The technical scheme that its technical problem that overcomes the utility model adopts is:
Intrinsic safety connector of the present utility model, comprise housing, be provided with through hole in the middle of the described housing, the diameter of described through hole is greater than the diameter of electric wire, it is taper that described housing head end is provided with its interior bone outer end of external screw thread, also comprise nut and sealing collar with taper hole, described sealing collar integral body is hexagon, the size of the conical surface B of its upper end and the size of housing outer end taper hole are complementary, the size of its lower end conical surface A and the taper hole size on the nut are complementary, and porose its aperture are set greater than the external diameter of electric wire in the described sealing collar.
In order better to realize fixed effect and sealing effectiveness, the conical surface B top of above-mentioned sealing collar is provided with sharp metal slice head.
The beneficial effects of the utility model are: electric wire is inserted in the hole of sealing collar, afterwards nut is screwed on the external screw thread of housing, along with screwing gradually of nut, the taper hole crush seal collar distortion of nut, under the taper hole effect of housing, extend upward and be fitted in the outer surface of electric wire from the conical surface B of sealing collar, its conical surface A extension downwards is fitted in the outer surface of electric wire, thereby has realized the sealing to electric wire.Assembling process simply saves time, and sealing property is reliable, has improved efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1. housing 2. nuts 3. conical surface A 4. seal collars 5. conical surface B 6. electric wires.
Embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing.
Intrinsic safety connector of the present utility model, comprise housing 1, be provided with through hole in the middle of the described housing 1, the diameter of described through hole is greater than the diameter of electric wire 6, it is taper that described housing 1 head end is provided with its interior bone outer end of external screw thread, also comprise nut 2 and sealing collar 4 with taper hole, described sealing collar 4 integral body are hexagon, the size of the conical surface B 5 of its upper end and the size of housing 1 outer end taper hole are complementary, the size of its lower end conical surface A 3 and the taper hole size on the nut 2 are complementary, and porose its aperture are set greater than the external diameter of electric wire 6 in the described sealing collar 4.Electric wire 6 is inserted in the hole of sealing collar 4, afterwards nut 2 is screwed on the external screw thread of housing 1, along with screwing gradually of nut 2, taper hole crush seal collar 4 distortion of nut 2, under the taper hole effect of housing 1, extend upward and be fitted in the outer surface of electric wire 6 from the conical surface B 5 of sealing collar 4, its conical surface A 3 extension downwards is fitted in the outer surface of electric wire 6, thereby has realized the sealing to electric wire.Assembling process simply saves time, and sealing property is reliable, has improved efficient.
Conical surface B 5 tops of above-mentioned sealing collar 4 are provided with sharp metal slice head.Sealing collar 4 metal slice heads are inserted into namely can play in the crust of electric wire 6 and prevent that electric wire 6 is loosening and can strengthen sealing again in the process that nut 2 screws.
Claims (2)
