Description
Technical field
The utility model belongs to cable connection area, is specifically related to a kind of cable quick plug.
Background technology
In prior art, the quick connection scheme of welding cable and welding cable and welding cable and welding equipment is all that plug and socket is in mating connection, socket is provided with guide groove along receptacle axis direction on jack inwall, and the end of described guide groove is along jack inner ring surface draw-in groove in the shape of a spiral.Bossed dop is established in the front end of plug, is inserted by plug during connection along female receptor groove guide, and then rotary connector makes the dop on plug rotate along helical form draw-in groove, and plug end face is contacted because screwing with socket end face.
There is following shortcoming in said structure: because plug and socket is integral type rigid structure, therefore the operational stroke of 1 ~ 2.5mm is only had between in use screwing and unscrewing, and in actual production work, because carrying, vibrating, collide, expand with heat and contract with cold and very easily make the dop of plug loosen from draw-in groove under the many factors such as cable pulling, cause virtual connection, cause energising surface current amount unstable, when big current by time plugs and sockets will generate heat, burn out connector, and have the danger of initiation fire.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of cable quick plug.Be provided with in this plug and form close-fitting flexible member with socket, when after plug insertion socket, plug clamping section traction flexible member forms axial tightening power, because the elastic working interval of flexible member is very wide, axial tightening power still can be made to meet design objective even if produce certain relatively rotating by external action between plug and socket in the course of the work, ensure the steadiness that both plug and sockets face that is energized contacts and reliability.
For achieving the above object, the utility model have employed following technical scheme:
A kind of cable quick plug, this quick plug comprises header body and flexible member; One end of described flexible member and stiff end are connected with header body is restricted, and the other end of flexible member and inserted terminal are provided with the clamping section forming elasticity with socket and be connected.
As preferred version of the present utility model, described flexible member is by secure component and header body is restricted links together.
As another kind of preferred version of the present utility model, the stiff end of described flexible member stretches into the inner side of header body and is connected with header body is restricted, and the inserted terminal of flexible member stretches out the outside in header body.
Preferably, described flexible member is helical spring; Clamping section on described helical spring for being arranged on the projection dop on spring silk, or stretches to for what be arranged on helical spring inserted terminal end the overhanging dop that spring curls up areas outside.
Preferably, the inserted terminal of described flexible member is bending.
Further, the center line of the bending part of described bending flexible member is in the same plane.
Preferably, the stiff end of described flexible member and header body form interference fit.
Preferably, described helical spring overhanging dop is straight arm shape or tilts shape.
Further, the degree of depth of the length and socket inner card cage that tilt shape overhanging dop matches.
Preferably, be provided with step inside one end that described header body is connected with helical spring, the end head of described helical spring stiff end is fastened on described step place.
Principle of the present utility model and beneficial effect as follows:
1), be provided with flexible member in the utility model, described flexible member both can be spring, also can for the bending parts bent by metal material, and also namely flexible member is essentially and can produces elastically-deformable energy storage component.
For the plug with spring, spring one end is connected with header body is restricted, and the other end tilts and is set to overhanging dop.During connection, the spring one end of plug inserts in socket, and rotary connector makes the overhanging dop of spring rotate along the helical form draw-in groove on socket, and extension spring forms axial tightening power, and the end face of plug and the end face of socket are fit together because of tightening force.Because the elastic working interval of spring is very wide, even if make the overhanging dop of spring and draw-in groove contact position that certain change occur by external action between plug and socket in the course of the work, the axial tightening power of spring still can meet design objective, thus make plug and socket continue and firmly combine, the stability that the energising face that ensure that contacts and reliability.
It is pointed out that the restricted connection in the utility model refers to that interconnective parts should closely combine.
In addition, the draw-in groove of socket in the shape of a spiral, with certain stroke.And the flexible member in the utility model is under elastically-deformable effect, the whole stroke of socket draw-in groove can be made full use of, also namely in the whole stroke of socket draw-in groove, the clamping section of flexible member all can under elastically-deformable effect tightly inlay card in the draw-in groove of socket.
2), in the utility model, the fixed form of spring and header body has multiple, such as can adopt that the mode of tensioner is restricted to link together, also can adopt that secure component is restricted to link together, the utility model preferably have employed the affixed mode of interference fit.Interference fit is not only easy to process, also ensure that the fastness combined between spring and header body.
3), in the utility model the overhanging dop of spring can be set to straight arm shape, also can be set to tilt shape.The overhanging section tilting shape can produce larger distortion, and the overhanging section therefore tilting shape can obtain better fastening effect.
