Present cylindrical electric connector is when plugging together, the general mode that is threaded that adopts realizes closely plugging together of connector plug and socket, this thread connecting mode is simple in structure, reliable operation, but operation relative complex, the fast-mating that can't realize plug and socket with separate, use inconvenient.
Patent application 201020112760 has proposed a kind of electrical connector plug and electric connector socket thereof, in this application, be provided with on the outer peripheral face of plug casing inserted terminal and plug together latch-up structure, the inserted terminal that plugs together latch-up structure has the elastic claw structure, be provided with the fixture block of projection on the termination of elastic claw, Socket casing endoporus inserted terminal is provided with the fixture block corresponding matching and realizes the draw-in groove that plugs and sockets reliably docks, when plug and socket plugs together, the inserted terminal of plug casing inserts the inserted terminal of Socket casing, the elastic claw that arranges on the plug inserted terminal shrinks, after connector plug and socket plug together, elastic claw opens, draw-in groove complementary fit on the fixture block of the projection of elastic claw and the Socket casing endoporus realizes reliably plugging together of connector plug and socket, when connector plug separates with socket, plug is applied a power, plug moves with respect to socket, deviates from the draw-in groove of the fixture block of the projection of elastic claw from the Socket casing endoporus, and elastic claw shrinks until connector plug separates with socket.The fast-mating that this structure can realize connector plug and socket with separate fast.But, elastic claw is that C shape elastic ring is realized, C shape elastic ring exists structure built on the sand, often stressed easy fracture, and the structure of annular can make the C shape elastic ring accuracy that run-off the straight meeting impact plugs together in motion process easily, causes occurring the situation that can not plug together.
Summary of the invention
Based on this, provide a kind of plug of cylindrical electric connector order of the present utility model, this plug construction is firm, can plug together fast, and reliability and accuracy are high.
Another purpose of the present utility model is to provide a kind of plug of cylindrical electric connector, and this plug construction is compact, good airproof performance, constructability and installation.
In order to achieve the above object, the utility model is realized in the following manner.
A kind of plug of cylindrical electric connector, this plug includes insulator, plug casing, contact pin, and a plurality of contact pins are set in the insulator, it is characterized in that this plug also includes elastic lock sleeve, described insulator is arranged in the elastic lock sleeve, and the plug casing cover lies on the elastic lock sleeve; Wherein, described plug casing has Access Division and accommodation section, and wedging position is in the front end of accommodation section, and the external diameter of Access Division is provided with at least one breach less than the accommodation section on the Access Division, so that tapered end protrudes from plug casing; Described elastic lock sleeve has elastic card buckle portion and a connecting portion, Elastic buckle section is positioned at the front end of connecting portion, and the external diameter of elastic card buckle portion is less than the external diameter of connecting portion, so that the elastic card buckle portion can be inserted in the above-mentioned Access Division smoothly, be provided with at least one outstanding tapered end on the elastic card buckle portion, tapered end stretches out in breach, cooperates with socket to carry out snap close; The end of described connecting portion is connected with the afterbody nut.
Have open slot on the described elastic card buckle portion, be extended with flexible connecting rod downwards from the top of open slot, the bottom of flexible connecting rod has tapered end.
Described tapered end, its cross section are triangle, trapezoidal or taper, so that can fast insert-pull under control.
Described plug also includes cable clip, the cable that connects in order to retrain contact pin, and described cable clip is positioned at the connecting portion of elastic lock sleeve, and the outer end is held by the afterbody nut.
Also be provided with the gib block that vertically arranges along the Access Division on the Access Division, so that plug and socket are pegged graft.
The joint portion of Access Division and accommodation section, the groove with a depression holds sealing ring in this groove, so that seal after pegging graft with socket.
Described elastic lock sleeve, the one end has external screw thread, to be connected with the afterbody nut; The external diameter of afterbody nut is connected with elastic lock sleeve so that extend in the accommodation section less than or equal to the internal diameter of above-mentioned accommodation section.
The utility model provides a kind of plug construction of cylinder shape connector that can fast insert-pull.This structure had both kept the convenient rapidly characteristics of electric connector plug, had kept again the steadiness of electric connector structure, had improved reliability and the accuracy of product.
Simultaneously, this plug construction is compact, good airproof performance, constructability and installation.
