Abstract
The utility model relates to an automatic secondary lock catch structure of a connector. The automatic secondary lock catch structure comprises a main body and a mounting base, wherein the mounting base is arranged on the main body, and outer pin holes are formed in positions of the left side edge and the right side edge of the mounting base respectively; a primary lock catch is arranged on the mounting base, wherein an inner pin hole is formed in a position where the middle of the primary lock catch is located; two rectangular fixed blocks are arranged on the rear portion of the mounting base, wherein the fixed blocks and the mounting base are of an integrated structure; a secondary lock catch is sleeved on the primary lock catch. According to the automatic secondary lock catch structure of the connector, the automatic secondary lock catch is used, primary locking and secondary locking or primary unlocking and secondary unlocking can be realized at the same time, automatic reset can be realized, therefore, the steps of manual secondary locking or unlocking are reduced, the situation that secondary locking is left out is prevented, and safety and stability are improved; meanwhile, simultaneous locking or unlocking of the primary lock catch and the secondary lock catch can be realized, the automatic secondary lock catch structure of the connector is easier and more convenient to use and operate, and can be used to support the use of various connectors.
Description
Technical field
The utility model relates to connector technique field, relates in particular to a kind of secondary auto-fastening structure of electric connector.
Background technology
At present, in the power supply unit (as new-energy automobile, steamer etc.) of some large electric currents, cable, as a kind of medium that conducts electricity, is also the part that must not lack, and meanwhile, is directly connected to the performance of power supply unit for the quality of the connector quality on cable.Probably minutes two kinds of the connectors of current use: a kind of employing be the structure of a snap close, although this easy to connect, for the generation of some fortuitous events, be difficult to its stability of assurance; What the second adopted is the structure of secondary snap close, after having inserted a snap close, need workman manually secondary snap close is pushed away (by, draw) put in place, as workman forgets, secondary snap close is pushed away (by, draw) put in place, secondary snap close is by ineffective.And when connector is unpluged, need workman separately to do more than twice or twice action, and meanwhile, operation is too complicated, and stability and security performance can not get good assurance.
Summary of the invention
The utility model provides the connector secondary that a kind of purposes is wide, easy to operate, performance is good auto-fastening structure in order to address the above problem.
In order to address the above problem, the technical solution adopted in the utility model is: a kind of connector secondary auto-fastening structure, comprise main body and mount pad, and described main body is provided with mount pad, and the left and right sides marginal position of described mount pad is respectively equipped with outer pin-and-hole; On described mount pad, be provided with snap close one time, and the position at the place, middle part of a snap close is provided with inner pinhole; The rear portion of described mount pad is provided with the fixed block of two rectangles, and fixed block and mount pad are integrated; On a described snap close, cover has secondary snap close.
The better effects if playing for snap close, between described outer pin-and-hole and inner pinhole, by latch fixed-link, and on latch medium position, cover has a torsion spring.
In order further a snap close to be had effect better, one end of a described snap close is connected with the guide pad of two rectangles, and guide pad and a snap close are integrated.
For the better effects if further snap close being played, the centre position at the guide pad place of described two rectangles is provided with a circular draw-in groove.
Self-locking better effects if for secondary snap close and snap close are played, is provided with a hollow chute in described secondary snap close, be provided with a block in described chute.
For the self-locking better effects if that further makes secondary snap close and snap close play, described block reverse side is established a root post, and column and block are integrated.
Self-locking better effects if in order further to make secondary snap close and snap close play, is provided with a Compress Spring between described draw-in groove and column.
Of the present utility model producing effect is: this connector has adopted secondary automatic locking, once lock or unblank with secondary to realize simultaneously and can automatically reset, reduced the step that artificial secondary is locked or unblanked, prevented from omitting the situation that secondary is locked, improved safety and stability, meanwhile, because once can realize and lock or unblank with secondary snap close simultaneously, use operation easier, and can supporting the use for multiple connector.
Accompanying drawing explanation
Fig. 1 is the structural representation of connector secondary auto-fastening structure described in the utility model;
Fig. 2 is the assembling schematic diagram of connector secondary auto-fastening structure described in the utility model;
Fig. 3 is the structural representation of secondary snap close described in the utility model;
In figure: 1-latch, 2-torsion spring, 3-main body, 31-mount pad, the outer pin-and-hole of 32-, 33-fixed block, snap close of 4-, 41-inner pinhole, 42-draw-in groove, 43-guide pad, 5-Compress Spring, bis-snap closes of 6-, 61-chute, 62-block, 63-column.
Embodiment
Below in conjunction with accompanying drawing, connector secondary auto-fastening structure described in the utility model is described in further detail:
As shown in Figure 1: a kind of connector secondary auto-fastening structure described in the utility model, comprise main body 3 and mount pad 31, described main body 3 is provided with mount pad 31, and the position, both sides of the edge of mount pad 31 is respectively equipped with outer pin-and-hole 32; On described mount pad 31, be provided with one time snap close 4, and the position at the place, middle part of a snap close 4 is provided with inner pinhole 41; The rear portion of described mount pad 31 is respectively equipped with the fixed block 33 of two rectangles, and fixed block 33 is integrated with mount pad 31; One end of a described snap close 4 is connected with the guide pad 43 of two rectangles, and guide pad 43 and a snap close 4 are integrated.The centre position at guide pad 43 places of two described rectangles is provided with a circular draw-in groove 42.Meanwhile, between outer pin-and-hole 32 and inner pinhole 41, by latch 1 fixed-link, and on latch 1 medium position, cover has a torsion spring 2, and torsion spring 2 can provide the torsion making progress for snap close 4 once here; On a described snap close 4, cover has secondary snap close 6, and in secondary snap close 6, is provided with a hollow chute 61, and in chute 61, is provided with a block 62, and described block 62 reverse side are established a root post 63, and column 63 is integrated with block 62; And, between described draw-in groove 42 and column 63, be provided with a Compress Spring 5, meanwhile, Compress Spring 5 one end are placed in chute 61, and the other end is placed on column 63, and the effect that Compress Spring 5 here plays is to provide an outside elastic force.
After a snap close 4 is locked, under the pressure of Compress Spring 5, promote backward secondary snap close 6, and prevent that by the fixed block 33 on mount pad 31 secondary snap close 6 from moving down, make secondary snap close 6 fixing, thereby reaching a snap close 4 can not rotate up and down, realize secondary automatic locking, and do not need to promote manually to lock; Again by promote forward and secondary snap close 6 is realized snap close 4 and secondary snap close 6 is opened to pressing down simultaneously, after opening, by the elasticity of torsion spring 2 and Compress Spring 5, recover to realize snap close 4 and secondary snap close 6 automatically resets.
