Abstract

The utility model discloses an industrial socket and a plug; the socket is composed of a fixing screw, a plug bush, a plug bush fixing stand and a socket stand and the plug is composed of a locking nut, a plug casing, a plug body, a bolt and a fixing screw. A cone-headed ejector pin is arranged inside the plug bush of the socket and abutting against the fixing screw. An expansion hole is arranged at the center of an expansion slot of the bolt of the plug. The cone head of the ejector pin faces rightly the expansion hole in interference fit. The utility model has the advantages of good connecting and contacting effect, non-deformation, long service life, security and reliability.

Description

A kind of socket for industry plug

One, technical field

The utility model belongs to the plugs and sockets technical field, especially relates to a kind of socket plug of industrial use.

Two, background technology

The socket for industry that institute produces and uses in the present actual life, the contact of plug is mainly finished by dual mode, first kind is that the latch of plug is finished the purpose of contact axially being sawn into two lobes by its elasticity, second kind is that the sleeve of socket is sawn into two to three lobes, finish the purpose of contact by its elasticity, but these two kinds all have not enough point, first kind of mode is permanent use after the external force of two semi-round bars when being used of latch gradually to internal strain, lose the desired elasticity of designer, and the diameter of the pole of actual contact equals to diminish comparatively speaking, loose contact causes producing electric spark, the second way also is also to follow the string after long-time the use, causes loose contact and produces electric spark.

Three, summary of the invention

The novel purpose of this use be to improve the deficiency of prior art and provide that a kind of plug sleeve closely contacts, indeformable, long service life, safe and reliable industrial socket plug.

The purpose of this utility model is to realize like this, a kind of socket for industry plug, form socket by fixed screw, sleeve, sleeve fixed mount and receptacle holders, form plug by locking nut, plug overcoat, plug body, latch and fixed screw, be characterized in the sleeve of socket, being provided with circular cone capitiform thimble near fixed screw, the dilatation joint center of the latch of plug is provided with inflation port, the nose cone of thimble and inflation port over against and interference fit.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts and be provided with circular cone capitiform thimble near fixed screw in the sleeve of socket, the dilatation joint center of the latch of plug is provided with inflation port, the nose cone of thimble and inflation port over against and interference fit, stretch into inflation port by thimble, thereby dilatation joint is expanded closely to be contacted with sleeve, this structure has guaranteed latch, sleeve is indeformable in the long-time back of using, contact is good, prolonged useful life, avoided latch, the sleeve loose contact produces the problem of electric spark, has guaranteed the safety of electric equipment.

Four, description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a plug construction schematic diagram of the present utility model.

Fig. 2 is a socket schematic diagram of the present utility model.

Fig. 3 is a partial sectional view of the present utility model.

Five, specific embodiments

Embodiment, a kind of socket for industry plug, with reference to Fig. 1, Fig. 2, Fig. 3, be to be fixed with sleeve fixed mount 4 on the receptacle holders 5 that insulate, be provided with sleeve 2 in the sleeve fixed mount 4, be provided with circular cone capitiform thimble 3 near fixed screw 1 in the sleeve 2, the outer wall of receptacle holders 5 is provided with screw thread, plug overcoat 7 internal fixation have plug body 8, the outside head of plug overcoat 7 be provided with can with the nut 6 that is threaded on the socket, plug body 8 is provided with latch 9, the rear portion of latch 9 is provided with fixed screw 10, and the dilatation joint center of latch 9 is provided with inflation port 11, the nose cone of thimble 3 and inflation port 11 over against and interference fit, sleeve in the present embodiment, latch is all 4, and this has constituted a kind of static structure of the present utility model.

When using the utility model, firmly with in the plug insertion socket, being about to latch 9 inserts in the sleeve 2, this moment, sleeve 2 interior thimbles 3 inserted in the inflation port 11 of latches 9, being threaded on the nut on the plug and the socket screwed, thimble 3 is got into along inflation port 11 simultaneously, two semicircle rods of latch 9 contact with sleeve 2 inwalls tightly at axial vertical direction spreading, nut is screwed to thimble 3 can not get into again till, guaranteed that like this latch 9 contacts with the tight of socket 2, contact is good, is fit to the requirement of big electric current, can not produce electric spark because of loose contact, guarantee the safety of electrical equipment.
