Embodiment

See also Fig. 3, Fig. 4 and Fig. 5, the side fastener of the utility model electric connector is the dual-side that is arranged at the plastics pedestal 35 of electric connector, uses the side that buckle inserts the circuit board 38 of electric connector, and it includes a main body 40 and an elastic arm 50, wherein:

This main body 40 includes a lamina perpendicularis 41 and a level board 42 that is vertical, lamina perpendicularis 41 1 sides are that integral body is connected so be a firm angular frame with level board 42 1 sides, the one end is connected in the configured slot 36 of plastics pedestal 35 1 sides, protrude forward in the middle of the front end of this lamina perpendicularis 41 and be provided with one first block 43, these first block, 43 belows form a space 44, direction level board 42 directions are bent to form one second transverse plate 49 on the front end of this lamina perpendicularis, the front end of this level board 42 is provided with a protuberance 45 forward, this protuberance 45 is provided with one second block 46, the leading portion of other this lamina perpendicularis 41 goes out one the 3rd block 47 to a side blow belling and uses the hole clipping 39 of fastening in circuit board 38 sides, these level board 42 upper punch bellings go out a grounding elastic part 48, and level board 42 rear ends connect a locating surface of down stretching 410.

The level board 42 that this elastic arm 50 is autonomous agents 40 upwards bending is vertical direction, its rear end 51 is connected in level board 42 and its front end 52 openings, its leading portion is provided with the clamping part 53 and a clicking section 54 of a buckle circuit board 38, the upper end of this clamping part 53 is the inclined-plane and the lower end is horizontal plane, its front end lower edge 55 is butted on second block 46 and is bent to form one first transverse plate 56 to first block 43 of this lamina perpendicularis 41, this first transverse plate 56 is positioned at second transverse plate, 49 belows of main body 40 and one side block in this second block 46, when elastic arm 50 during to lamina perpendicularis 41 springing of this main body 40, this first transverse plate 56 can support and terminate in this first block 43.

See also Fig. 6, in the time of after circuit board 38 tilts to insert electric connector, will depressing the location, can oppress the inclined-plane of clamping part 53 upper ends of elastic arm 50 earlier, make elastic arm 50 to lamina perpendicularis 41 springing, this moment, the front end lower edge 55 of elastic arm 50 left second block 46, and first transverse plate 56 supports and terminates in first block 43 simultaneously.

See also Fig. 7, lasting when pressing down when circuit board 38, first transverse plate 56 of elastic arm 50 is subjected to stopping of first block 43, so can only move down; See also Fig. 8, circuit board 38 continues when pressing down, and this moment, first transverse plate 56 of elastic arm 50 broke away from stopping of first block 43, so can be moved laterally by the space 44 of first block, 43 belows; See also Fig. 5, when circuit board 38 skidded off the inclined-plane of clamping part 53 upper ends, elastic arm 50 was that resilience makes clamping part 53 fastenings above circuit board 38, the 3rd block 47 then fastening in the hole clipping 39 of circuit board 38.

More than be the action specification of inserting

circuit board

38,54 elastic arm reached outward slightly depress springing from the clicking section with finger, can make circuit board break away from clamping part 53 and tripping so can be taken out if will take off 38 of circuit boards.Though need have in the operation and press work, so can't cause operational inconvenience, because the stroke that the utility model pressed down is very short, and when stirring, have the component that some press down naturally, so when first transverse plate 56 is stopped by first baffle plate 43, it is displaced sideways toward coming downwards to space 44 naturally again, so still very smooth and easy in the operation.

See also Fig. 5, after circuit board 38 inclination insertion electric connectors are depressed the location, clamping part 53 be snapped on the

circuit board

38 and 47 fastenings of the 3rd block in the hole clipping 39 of circuit board 38 sides, firm by this locating circuit board 38, this moment, the front end lower edge 55 of elastic arm 50 was butted on second block 46 of main body 40, and second transverse plate 49 of main body 40 is butted on first transverse plate 56 of elastic arm 50, so when testing with impulsive force up and down, because elastic arm 50 is subjected to second transverse plate 49 and second block, the 46 fastening above-below directions of main body 40, so can not be shifted because of impulsive force up and down.

See also Fig. 9, when with the test of the impulsive force of side direction, when elastic arm 50 was displaced sideways because of the impact force action of side direction, first transverse plate 56 can support and terminate in first block 43, this moment, clamping part 53 still was snapped on the circuit board 38, so not reason lateral forces and tripping disengaging of circuit board 38.

Though by above explanation as can be known the utility model structure under the impulsive force up and down or the impact of the impulsive force of side direction, all can make circuit board 38 that firm location is arranged, especially all can make clamping part 53 still in the scope of buckle circuit board 38 moving of the elastic arm that impulsive force causes 50 of side direction, solve the impulsive force problem that known person is difficult to resist side direction.

The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to be easy to illustrate technology contents of the present utility model, and be not with the utility model narrow sense be limited to this embodiment, the utility model is to make many variations when implementing.
