Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, is meant that especially a kind of both sides are provided with the electric connector of side retainer.

[background technology]

See also Fig. 1, be known electric connector, it is to include an insulation shell 11, most the first terminal 12, most second terminal 13, and two side retainers 14, wherein this first terminal 12 is terminal grooves that row is located at these insulation shell 11 front rows, and its pin 121 is the bottom surface that level is positioned at this insulation shell 11; This second terminal 13 is terminal grooves that row is located at this insulation shell 11 back rows, and its pin 131 also is the bottom surface that level is positioned at this insulation shell 11, is the same level face with the pin 121 of the first terminal 12; This side retainer 14 is both sides that installing is positioned this insulation shell 11, it is to be provided with a locating surface 141 and an elastic arm 142, this locating surface 141 is same horizontal plane with the pin 121,131 of first and

second terminal

12,13, this elastic arm 142 be provided with a clamping part 143 near end.

When electric connector is welded in motherboard when (figure does not show), because the length of this side retainer 14 is very long, so need to be fixedly welded on motherboard by this locating surface 141, when the circuit board 15 of desire connection inserted connection, this clamping part 143 can be snapped in the hole clipping 151 of circuit board both sides.

[embodiment]

Seeing also Fig. 2 and Fig. 3, is the utility model one preferred embodiment, and it is to include: an insulation shell 20, most the first terminal 40, most second terminal 45, and two side retainers 50, wherein:

Please cooperate and consult Fig. 4, Fig. 5 and Fig. 6, this insulation shell 20, be that row is provided with the first terminal groove 21 and second terminal groove 22,22 of this first terminal groove 21 and second terminal grooves form a link slot 27, its both sides respectively are provided with a location notch 23, and these location notch 23 1 sides are provided with a flexure strip 24, and the inner face of this flexure strip 24 is provided with a fixture block, be to be a projection 25, this projection 25 is provided with and imports inclined-plane 26.

This first terminal 40 is to be inserted in the first terminal groove 21 of this insulation shell, and its pin 41 is the bottom surface that level is positioned at this insulation shell 20.

This second terminal 45 is to be inserted in second terminal groove 22 of this insulation shell, and its pin 46 is the bottom surface that level is positioned at this insulation shell 20.

Please cooperate and consult Fig. 7, Fig. 8, Fig. 9 and Figure 10, this side retainer 50 is provided with a main body 51, it is to make with the good metal material punching press of elasticity, the one end is provided with a wedged connecting structure, it is the blocked hole 52 for circle, its other end is provided with an elastic arm 53 and a level board 54 longitudinally, these elastic arm 53 1 ends are provided with Plug Division 55, this Plug Division stamps out an elastic clamping hook 56, these level board 54 both sides respectively are provided with first block 57, second block 58 of a projection respectively, and plate face central authorities down stamp out a level to locating surface 59; An and fastener 61, it is with the plastic material ejection formation, the one end is provided with Plug Division 55 insertions that connecting hole 62 can be this main body 51, be provided with elastic clamping hook 56 fastenings that groove 63 (see figure 10)s can be this main body 51 in this connecting hole 62, the one side is provided with a draw-in groove 64 and an interlocking portion 65, this draw-in groove 64 is provided with an end face 66 and a side is open, the other end then connects this interlocking portion 65, first block 57 of the corresponding main body 51 in its bottom surface, second block 58 is provided with first groove 67, second groove, 68 (see figure 9)s, when this fastener 61 can be respectively this first block 57 during to two side shiftings, 58 blocks of second block, one end of other first groove 67 is provided with guiding incline 69, but in order to first groove, the 67 packings assembling of first block 57 with the fastener 61 of main body 51, using and making both is benchmark with second block 58 in assembling.

By above structure, when the main body 51 of this side retainer 5 is inserted location notch 23 location of insulation shell, this flexure strip 24 is backed down earlier, its blocked hole 52 is projection 25 clampings of flexure strip 24 inner faces after main body 51 enters, because this projection 25 is provided with the elasticity that imports inclined-plane 26 and cooperate flexure strip 25, thus be very easy to assembly, and can form firm clamping effect, the packing of need not exerting all one's strength in the assembling, the destruction that also can not cause insulation shell.

In the use, the utility model is that weldering is tied on motherboard, because side retainer 50 still can pivot after assembling with insulating base frame 20, form coplane so can guarantee its locating surface 59 and the pin 41 of terminal 40 and the pin 46 of terminal 45, when the link slot 27 of circuit board insertion insulation shell 20 connects, the interlocking portion 65 that the hole clipping of its both sides can be side retainer 50 fastens, the circuit board side then snaps in draw-in groove 64, so circuit board is subjected to the blocking of fore-and-aft direction and above-below direction, can reach fixed effect.

Side retainer 50 of the present utility model is to adopt main body 51 and fastener 61 to make recombinant respectively to form, so can select for use suitable material to make according to need in manufacturing, except the foregoing description mode, this fastener 61 also can adopt aluminium extruded type or metal stamping and pressing moulding to make.

So reason of assembling the side retainer easily of the present utility model be when assembling this side retainer wedged connecting structure be to be the location notch that relaxed state enters insulation shell, make buckle by the springing of the flexure strip of insulation shell again, so more or less freely in the assembling.

Moreover, when these blocked hole 52 circular holes, the main body 51 that can make side retainer 50 is that pivot pivots with the projection 25 of this insulation shell 20, so can adjust the position of its locating surface 59 by the pivot of main body 51, make the

41,46 that cooperates first and

second terminal

40,45 form coplane effect person.

Because the utility model this side retainer and insulating base frame in design still can pivot after assembling, moving interval with an above-below direction, so suitable tolerance of tolerable on making, still all can reach the demand of side retainer and terminal coplane, so make to go up more or less freely and more can guarantee the effect of coplane.

The wedged connecting structure of side retainer is to adopt blocked hole in the above-described embodiments, and the fixture block on the flexure strip of insulation shell directly is designed to a projection and cooperates clamping to get final product with blocked hole; Right if the wedged connecting structure of side retainer is designed to projection, then the fixture block on the flexure strip of insulation shell then can middlely design groove or bore a hole and cooperate clamping, so also can reach same effect.

Cooperating and consult Figure 11 and Figure 12, is another embodiment for side retainer of the present utility model, and its difference is that this elastic arm 53 is to adopt to a lateral buckling to form an elasticity arm of force, and this locating surface then is to adopt downward bending mode to form in addition.

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 also can be made many variations and implement.
