Description

The plastic casing of zero elevation board to board connector

The utility model relates to connector shell.

Existing connector shell is shown in Fig. 1,3: plastic casing 1 has the chute 10 of a depression to embed for a gusset 11 levels, and it is relative to be formed with lug 14 at bone groove 10 both sides inwall ora terminalis, this gusset 11 has parallel round arranged side by side 12, using provides whole row's guide pin 13 to plant, and obtains suitable clamping effect through the packing of chute 10 both sides lugs 14; It is equipped with three flanges arranged side by side 15 in the bottom surface, 15 of each flanges are reserved with dead slot and set for guide pin 13, and sees through flange 15 to each other to the interfering edge of guide pin.Make guide pin reach packing.By said structure, shown in Fig. 2,4: in the use, the connector that assembling is finished is arranged on the circuit board, and makes circuit board through welding, makes guide pin 13 and circuit board solid welding together, then through after the processes such as cleaning, plastic casing 1 is removed again; But with regard to first kind of structure, it is in removing housing 1 process, be mode from housing 1 both sides towards the central application of force, the fastening force that impels lug 14 to discharge to guide pin 13, and smoothly 1 group of housing is risen, right second kind of structure removes in the operation housing 1, then is to utilize mechanical arm or artificial hand to dial pattern, directly its group risen.These two kinds of plastic casing structures have following disappearance in the use:

1, first kind of connector plastic cement housing, owing to this gusset must embed in assembling in a horizontal manner,

Combination smoothly, but because of this plastic casing and gusset are very little on actual size, and both

Between adaptation must keep certain program again, otherwise will cause guide pin to press from both sides smoothly to pull fixing,

So structurally be difficult for reaching, and rather waste time and energy.

2, be installed on the circuit board and desire has been dialled when separating with guide pin when it, must be from two outsides towards central authorities

The fashion of extrusion of the application of force makes space increase between chute two side and gusset; Making guide pin break away from it compels

Tight effect and keeping somewhere smoothly on circuit board; This kind mode because of application of force inequality, causes portion easily

Part guide pin can't separate smoothly, and increases the puzzlement on using.

3, second kind of connector plastic cement housing is owing to only utilize the interfering edge between flat board that the guide pin clamping is unlikely

Come off,, can't separate plastic casing and guide pin smoothly in case interfering edge is too big; Interfering edge too

Little, come off because of external or human factor form in welding process easily again.

The purpose of this utility model provides a kind of plastic casing of the zero elevation board to board connector of again can be fast, easily plastic casing being separated with guide pin easy to assembly.

The purpose of this utility model is achieved in that the plastic casing of zero elevation board to board connector, comprise base, loam cake, it is characterized in that: susceptor surface central authorities are provided with the protuberance flank, both sides are that longitudinal fluting is arranged side by side, through hole has been passed through in the bottom, and the groove outside is corresponding jagged, and the breach inner face has oblique guiding face, the flank two ends are arranged with clamping face and keep supplying the mutual buckle of lid, and there are one a group of stop block and a flange in the surface; The loam cake top is that plane and two ends respectively are provided with a fastener that dead slot arranged, its bottom surface is provided with side by side and corresponding wedge, every group of relative inner face of wedge all forms wavy surface, and different lateral surface then forms oblique chimeric surface, uses to be subjected to the guiding face effect to embed formation packing in the breach.

Above-mentioned design, be subjected to wedge wavy surface and the mutual packing of breach to reach certain locating effect the guide pin that inserts, and when separating, make the packing of wedge release by mentioning loam cake to guide pin, and utilize fastener and stop block to detain card mutually, base is taken up in the lump, reach easily plastic casing is removed, and guide pin is kept somewhere effect in circuit board.

Be described further again below by accompanying drawing, embodiment.

Shown in Fig. 5-7: the utility model comprises base 20, loam cake 30, it is characterized in that: base 20 surperficial central authorities are provided with protuberance flank 21, both sides are that longitudinal fluting 22 is arranged side by side, through hole 24 has been passed through in the bottom, groove 22 outsides corresponding jagged 23, breach 23 inner faces have oblique guiding face 2 31, and flank 21 two ends are arranged with clamping face 26 and keep supplying and cover 30 mutual buckles, and there are one a group of stop block 27 and a flange 28 in the surface; Loam cake 30 tops are that plane and two ends respectively are provided with a fastener 31 that dead slot 32 arranged, its bottom surface is provided with side by side and corresponding wedge 34, every group of wedge 34 relative inner faces all form wavy surface 35, different lateral surface then forms oblique chimeric surface 36, uses to be subjected to guiding face 231 effects to embed formation packing in the breach 23.Wherein, stop block 27 has an inclined-plane grab 271 that is negative angle, and the two sides of flange 28 corresponding its directions are the inclined-plane 281 of gradient than orle.Wherein, the through hole 24 that extends out is formed on groove 22 bottoms, provides guide pin 25 to insert smoothly; Wherein, the dead slot 32 of fastener 31 embeds for stop block 27 flanges 28, and the internal face of dead slot 32 belows forms one and be negative inclined-plane grab 33, for and stop block 27 form mutually and fix, wherein, the gradient of the guiding face 231 of breach 23 is the gradient that is slightly larger than wedge 34 outside chimeric surfaces 36.Chimeric surface 36 is combined closely by the effect formation of guiding face 231.

Shown in Fig. 8,9: base 20 combines with loam cake 30, and every group of wedge 34 all embedded in the breach 23, and impels the inclined-plane grab 33 of fastener 31 to be snapped on the inclined-plane 281 of flange 28.Will the row of putting in order or whole group guide pin 25 insert by through hole 24, when guide pin 25 ran through and protrudes in groove 22, because gradient forces wedge 34 close to flank 21, mat wavy surface and more form packing made guide pin 25 can not cause loosening or come off because of the soldering operation; Again the connector of finishing is positioned over precalculated position on the circuit board, so that weld, all guide pins 25 are integral with the circuit board solid welding, upwards mention loam cake at last because chimeric surface 36 reinstatements are closed in wedge 34 outsides, and release is to the fastening force of guide pin, in the lump base is taken up simultaneously, easily plastic casing is removed and reach, and all guide pins are kept somewhere in circuit board.

Shown in Figure 10,11, in conjunction with the time, providing the clip pattern of fastener 31 inclined-plane grabs 33 in base 20 both sides stop blocks 27 and flange 28 is inclined-plane grab 271 and inclined-plane 281 designs that are negative angle, therefore, does not cost power and just can easily apace it be combined into one; Clamping structure is when having dialled loam cake, then can form the fixing effect of certain restriction, and since flange 28 to have the gradient that is inclined-plane 281 bigger, so fastener 31 can not be limited influence and can break away from smoothly, but when upwards meeting with stop block 27, then coincide mutually and reach the restriction of certain buckle, and be able to the effectiveness that when having dialled loam cake 30, in the lump base 20 taken up because of the inclined-plane grab 271 of its inclined-plane grab 33 and stop block 27 forms.
