Description
Technical field
The present invention relates to a kind of female terminal structure of connector, particularly one connector used for electric vehicle.
Background technology
Along with the propelling of electric automobile, the application of connector used for electric vehicle is more and more extensive, and require more and more higher to the contact reliability of connector contact, current connector used for electric vehicle generally adopts wire spring socket as the female end of plug connector, the connector female end used for electric vehicle of current appearance is that line spring one end and the bending of inner sleeve one end are fixed, dispersing sexual state outside the line spring other end stretches in the inner sleeve other end, overcoat is set in outside of inner cover by split-type structural, this kind of structure makes the line spring other end and workpiece push against by line spring one end elasticity of flexure after the male end of connector is inserted, the grafting realizing male and female end is fixed, this kind of structure contact engaging and separating force is little, Long-Time Service line spring is easily out of shape the power of following the string, cause connector loose contact, and due to the line spring other end be diversity structure, it easily occurs to be wound around distortion in inner sleeve, follow the string and push against power, it is gone back easily and overcoat inside bottom surface interferes, male end is caused to be difficult to insert and extract smoothly, and due to overcoat be split, after Long-Time Service, overcoat easily gets loose, connector is caused to lose efficacy.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of connector used for electric vehicle, this connector structure used for electric vehicle is simple, and firm plug, uses stable, long service life.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of connector used for electric vehicle, comprise overcoat, inner sleeve and line spring, described inner sleeve is Ring-cylindrical structure, some line springs successively along inner sleeve madial wall arrangement and inner sleeve medial surface is entirely coated, the outside bending of line spring inward at both ends cover is also coated on outside inner sleeve two ends, line spring is positioned at the arcuate structure that the part inside inner sleeve is protruded towards inner sleeve axis direction in centre, overcoat one end is provided with cylindrical chamber, and inner sleeve and the line spring put in being coated on just closely are inserted in the cylindrical chamber of overcoat one end.
As the further improvement of invention, there is angle in described some line spring bearing of trends and inner sleeve generatrix direction.
As the further improvement of invention, described line spring bearing of trend and inner sleeve generatrix direction angle are 7 °-11 °.
As the further improvement of invention, described inner sleeve periphery both ends form the ledge structure that radial direction inside contracts, and the bending edges at line spring two ends is just placed in the space that ledge structure that overcoat and inner sleeve lateral wall inside contract formed, and inner sleeve interlude is tight against overcoat madial wall.
As the further improvement of invention, described overcoat is structure as a whole.
As the further improvement of invention, the cylindrical chamber opening part of described overcoat one end forms the expanding structure that a loop diameter extends out, and this expanding structure internal fixtion is inserted with protection decorative cover, and protection decorative cover is covered in the line spring bending edges of inner sleeve end just completely.
As the further improvement of invention, one end that described protection decorative cover overlaps open outer side is toward the outside concordant with overcoat one end end face.
As the further improvement of invention, the inside edge, one end that described protection decorative cover overlaps open outer side is toward the outside formed with fillet structure.
As the further improvement of invention, described sleeve side wall is also provided with the venthole be communicated with cylindrical chamber root.
Advantageous Effects of the present invention is: the present invention is by adopting dog leg line spring, and in the middle of online spring, the curvilinear structures protruded towards inner sleeve axis direction is set, substantially increase the elasticity of line spring, and can keep for a long time not easily deforming, by line spring in the tilted distribution of inner sleeve, improve the contact area of line spring and male end, further increase contact engaging and separating force, the long-time stability that effective maintenance connector connects, overcoat adopts integrative-structure, ensure that it is combined with inner sleeve long-term close, avoid getting loose, effectively extend the life-span of connector, arrange protection decorative cover at mantle cavity body opening part to protect line spring bending edges, truncation Line spring bending edges when avoiding public terminal plug to insert, line spring bending edges is avoided to be hit distortion, its elastic force is avoided to weaken, structure of the present invention is simple, grafting is stablized, not yielding, long service life, good looking appearance.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present invention.
Embodiment
Embodiment: a kind of connector used for electric vehicle, comprise overcoat 1, inner sleeve 2 and line spring 3, described inner sleeve 2 is in Ring-cylindrical structure, some line springs 3 are successively along the arrangement of inner sleeve 2 madial wall and by entirely coated for inner sleeve 2 medial surface, bending outside line spring 3 inward at both ends cover 2 is also coated on outside inner sleeve 2 two ends, line spring 3 is positioned at the arcuate structure that the part inside inner sleeve 2 is protruded towards inner sleeve 2 axis direction in centre, overcoat 1 one end is provided with cylindrical chamber, and inner sleeve 2 and the line spring 3 be coated in inner sleeve 2 are just closely inserted in the cylindrical chamber of overcoat 1 one end.
The coated inner sleeve 2 of line spring 3 two ends bending, realize the stationary positioned of line spring 3, simultaneously for line spring 3 provides the elastic force along inner sleeve 2 radial direction, line spring 3 is positioned at inner sleeve 2 inboard portion in the curvilinear structures protruded to inner sleeve 2 inside, the elastic range that line spring is 3 is large, when connector male inserts, line spring 3 two ends and centre all provide elastic force tightly to prop up male end circumferential surface, ensure that connector male and female end connects closely, avoid the deformation failure of Long-Time Service line spring 3, and line spring 3 two ends are all fixed, not easily there is confusion and winding in its ordered arrangement in inner sleeve 2, more can not there is mutual interference, can ensure that male end is inserted smoothly and extracts, and this connector structure is simple, be convenient to manufacture, low cost of manufacture, long service life.
