Embodiment

Please consult Fig. 1 simultaneously to shown in Figure 5, be to be three-dimensional exploded view of the present utility model, Figure 1A enlarged drawing partly, another three-dimensional exploded view, the three-dimensional exploded view of user mode, the top view of elastic lock and user mode stereo appearance figure, find out by knowing among the figure, the buckle structure of the utility model electric connector is by an insulating body 1, be located at the elastic lock 2 of insulating body 1 two sides, a complex conduction terminal 3 and a shield shell 4 are formed, so with regard to the primary structure feature of this case describe in detail as after, present embodiment is to be considered as the place ahead with the direction that electric connector of the present utility model is plugged in butt connector; Wherein:

Insulating body 1 is to make with plastic insulation material, this insulating body 1 has a base portion 11, be provided with plural terminals caulking groove 111 on the bottom surface of base portion 11, be provided with the slot 112 of an elongated corresponding to the below of these terminal caulking grooves 111, the rear two side outer rims of this base portion 11 respectively are provided with a protruding button 113 again;

Base portion 11 2 side central authorities are the integrated elastic locks 2 that stretch out, elastic lock 2 is divided into the buckling parts 21 that is positioned at leading portion again, and be positioned at the operating portion 22 of back segment, the terminal inboard of this operating portion 22 is and the terminal elastic arm 221 with elastic force that is connected of two sides of base portion 11, elastic arm 221 is made of one piece with base portion 11, the front end of the top surface of buckling parts 21 is to be provided with a profile groove 211, the bottom of this profile groove 211 is provided with one again and holds groove 212 under the arm, and profile groove 211 is to be used for being embedded a metal buckle 213;

Complex conduction terminal 3 is to make with the metal material with conductivity, and its front end is to have a butt end 31, and end is an Elastic Contact end 32;

Shield shell 4 is to make for metal material, and shield shell 4 bends a spacer 41 downwards corresponding to the position of aforementioned protruding button 113, and this spacer 41 is provided with a slotted eye 42 that can be fastened on this protruding button 113;

By above-mentioned member in when assembling, be that complex conduction terminal 3 is planted in the terminal caulking groove 111 by the bottom surface at insulating body 1 rear, the Elastic Contact end 32 of these conducting terminals 3 is to project upwards terminal caulking groove 111 outer (as shown in Figure 3), and then buckle 213 is assembled in from top to bottom in the profile groove 211 of buckling parts 21 front ends, after in buckle 213 is assembled in profile groove 211, again buckle 213 is pushed forward, buckle 213 is embedded hold location in the groove 212 under the arm, to make buckle 213 can not break away from, at last shield shell 4 is assembled on the insulating body 1 from top to bottom, slotted eye 42 on the spacer 41 is to buckle on the protruding button 113 of base portion 11 2 sides, make shield shell 4 firm covers overlay on insulating body 1 top, promptly finish the assembling of the utility model integral body.

In addition, elastic lock 2 of the present utility model also can be formed in one and make the structure that front end has buckle, so structure just need not installed metal buckle at front end in addition, and as shown in Figure 3, slot 112 of the present utility model is to be used to provide a flexible flat cable 5 to be inserted in it, the side that makes flexible flat cable 5 have contact 51 is flattened on the surface of Elastic Contact end 32, electrically connect to form, can assemble a fixed head 6 on flexible flat cable 5 surfaces more then, fixed head 6 is pushed down flexible flat cable 5, come off to prevent flexible flat cable 5.

The utility model is operating portion 22 outsides of pushing elastic lock 2 in use, make elastic lock 2 starts, be able to the utility model is planted on the butt connector (not shown), then the application of force is removed, operating portion 22 promptly utilizes the resilience force of itself and resets, make buckle 213 can be fastened on the butt connector, because

operating portion

22 and 11 of base portions have an elastic arm 221, therefore not only make operating portion 22 have preferable elastic force and have outside the preferable feel when pushing, can promote the resilience force of elastic lock 2 again, make elastic lock 2 more firm when fastening, and then can prolong whole useful life.In addition, elastic lock 2 is made of one piece with base portion 11, again in the buckling parts 21 front ends less metal buckle 213 of a volume of arranging in pairs or groups, reducing the manufacturing cost of buckle 213, and then not only can save whole cost and can promote chucking power again.
