Embodiment

See also Fig. 3 and Fig. 4, but being fastening, the ear clip device of the utility model electric connector inserts a side hole clipping 28 of the circuit board 27 of this electric connector, this electric connector includes: a plastics pedestal 30 and be located at terminal (non-this case design focal point of this plastics pedestal, so figure does not show), this ear clip device includes: panel element 40 and two hook parts 50 together, wherein:

The both sides of this plastics pedestal 30 all are provided with a storage tank 31 (diagram only simply illustrate a side), and the front and back ends of storage tank 31 respectively is provided with a pivoted hole 32.

This rise panel element 40 before, the rear end respectively is provided with the pivoted hole 32 that a pivot 41 is articulated in this plastics pedestal 30, it can rotate in this storage tank 31, its lower end is provided with one to the projecting inward jacking block 42 of plastics pedestal 30, this jacking block 42 peaks at a side-lower of this circuit board 27, play panel element 40 upper ends and be provided with a press section 43 and to the projecting inward clamping part 44 of plastics pedestal 30, these clamping part 44 fastenings are in a side hole clipping 28 of circuit board, this press section 43 is a horizontal shell fragment shape makes its springing up and down, one-body molded this clamping part 44 that is connected in of one end, its other end extends one downwards and is longitudinal slice 45 longitudinally, the front and back end of this longitudinal slice 45 respectively is provided with a groove 46, the below of this groove 46 is provided with 47 outsides, 47, the first inclined-planes, first inclined-plane that are inclination and is provided with first a card face 48 that is vertical plane.

This two hook part 50 is to collude the front and back ends that body is located at this plastics pedestal 30 1 sides top down, it is provided with the second card face 52 that second inclined-plane 51 and that is inclination is vertical plane, and this two hook part 50 is to play a groove 46 of panel element 40 and make its second card face 52 be stuck in the first card face 48 of panel element 40 through this respectively.

By above structure, use operation as follows, see also Fig. 5, when circuit board 27 inserted plastics pedestal 30, circuit board 27 1 side lower ends were to compress this jacking block that plays panel element 40 42 earlier, so made panel element 40 pivot to plastics pedestal 30.

See also Fig. 6, gradually go to the location when making its clamping part 44 fasten the hole clipping 28 of circuit boards, can the be bonded with each other extruding and make this pressure section 43 downward springing of second inclined-plane 51 of this first inclined-plane 47 that plays panel element 40 and hook part 50 when playing panel element 40.

When circuit board 27 continues to pressing down, when first inclined-plane 47 that has made panel element 40 staggers with second inclined-plane 51 of hook part 50, this pressure section 43 i.e. upwards resilience, as shown in Figure 4, play the second card face, the 52 mutual clampings of the first card face 48 with the hook part 50 of panel element 40, the clamping part 44 that play panel element 40 this moment is sticked in the hole clipping 28 of circuit board 27, and makes circuit board 27 locate really.

See also Fig. 7, in the time will taking off circuit board 27, pushing this press section 43 makes these longitudinal slice 45 declines and this first card face 48 and the second card face 52 is staggered and clamping no longer mutually, so can toward the 30 outer sideway swivels of plastics pedestal this play panel element 40, with circuit board 27 jack-up, 50 of this hook parts withdraw from via this groove 46.

By above explanation, the utility model can be concluded following advantage:

1. play panel element 40 behind fastening circuit board 27, play the second card face, the 52 mutual clampings of the first card face 48 with the hook part 50 of panel element 40, the panel element 40 of having died has clear and definite trip effect with plastics pedestal 30, if collude then this and play panel element 40 and can't pivot with respect to plastics pedestal 30 without taking off, so can guarantee the electrical connection of circuit board 27, reason is not subjected to the vibration of external force and has made panel element 40 produce pivot.

2. though need to do to take off to collude action in the operation of taking off circuit board 27, so take off collude the action be directly to push this press section 43, and the panel element 40 that pivoted also is to push this press section 43, to collude and pivot all be to push same position so take off, almost be that an action is finished, so can not cause inconvenience in the use because of trip design.

See also Fig. 8 and Fig. 9, be the utility model second embodiment, it is to include a panel element 40 and a hook part 50 together, it is identical with first embodiment haply, wherein difference is that the centre of this longitudinal slice that plays panel element 40 45 is provided with a groove 46, and this hook part 50 is located at the centre of this plastics pedestal 30 1 sides top; This is provided with a perforation 410 to make this hook part 50 be passed in the middle of playing panel element 40 epimeres in addition.

See also Figure 10, be the utility model the 3rd embodiment, it is identical with second embodiment haply, wherein difference is that the groove 46 of this longitudinal slice that plays panel element 40 45 connects a finedraw 410 to longitudinal slice 45 lower ends, so can make this longitudinal slice 45 slightly have the elasticity that to uphold, make when hook part 50 breaks away from via groove 46 comparatively smooth and easy.

More than the specific embodiment that in the detailed description of preferred embodiment, proposed 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, in fact, the utility model can be made many variations and implement.
