Description
[technical field]
The utility model relates generally to a kind of electric coupler component of tool taking and holding device.
[background technology]
Electric connector is welded in the process on the circuit board, and industry generally adopts the vacsorb device to hold electric connector so that mechanically actuated operation effectively is positioned it on circuit board.But because of electric connector itself is not provided with the smooth flat that can supply the vacsorb device to draw, so, need usually finish suction operation by the taking and holding device that is installed on the electric connector.Promptly disclosed a kind of electric coupler component of tool taking and holding device for No. 6413111 as the United States Patent (USP) of announcing on July 2nd, 2002.
At present, the electric coupler component of a kind of tool taking and holding device that industry adopts, as shown in Figures 1 and 2, the electric connector 6 that should have electric coupler component 5 now is installed on the circuit board (not icon), this electric connector 6 has a top 61, a bottom 62 and four sides 63, these electric connector 6 tops 61 are arranged with and form a terminal conduction region 64, this conduction region 64 offers a plurality of terminal containing slots 641, contain conducting terminal 65 in these terminal containing slots 641, described conducting terminal 65 protrudes in terminal conduction region 64 surfaces.Described electric connector 6 is at 62 places, described bottom, from two opposite sides end 63 respectively symmetry be concaved with two grooves 66, and two opposite sides end 63 forms a limiting section 67 in the upper end of described groove 66.
The taking and holding device 7 that is used with this electric connector 6, system is installed on the described electric connector 6, described taking and holding device 7 comprises and is provided with the base portion 71 that smooth flat is drawn for vacsorb device (not icon), extend outward one first extension 72 and second extension 73 respectively by these base portion 71 two opposite sides ends, wherein said first extension 72 is provided with an operating portion 74 away from base portion 71 1 ends to extending away from the direction of base portion 71, the force application location when this operating portion 74 picks and places this taking and holding device 7 for the operator.Described first extension 72 and described second extension 73 respectively at away from base portion 71 1 ends to being provided with a holding part 75 with electric connector 6 combined directions (being downward direction herein) vertical extent, a hook part 76 is equipped with at the two ends of a side of these holding part 75 contiguous electric connectors 6 respectively.
When described taking and holding device 7 and described electric connector 6 are combined, firmly press down, two relative holding parts 75 are out of shape to the outside of described electric connector 6, thereby two described hook parts 76 are sticked in the corresponding recesses 66 of described electric connector 6 respectively, and fasten, and then described taking and holding device 7 is fixed on the described electric connector 6 with described limiting section 67 interferences.At this moment, vacsorb device (not icon) is drawn the smooth domain on base portion 71 surfaces of described taking and holding device 7, gets final product the precalculated position that the mat mechanically actuated operation effectively is positioned described electric connector 6 circuit board (not icon).
But because of described taking and holding device 7 and 6 of described electric connectors are sticked in respectively with two described hook parts in the groove 66 of described insulating body 61, and fasten with described limiting section 67 interferences, to reach the fastening effect of 6 of described taking and holding device 7 and described electric connectors, thereby when with described taking and holding device 7 when described electric connector 6 takes off, the thumb of one side hand of operator is broken described operating portion 74 obliquely off with the fingers and thumb, its normal application of force direction as shown in Figure 2, be obliquely a removal force F, this removal force F will produce a horizontal component Fx and a vertical component Fy who makes progress, its horizontal component Fx can make described taking and holding device 7 and 6 of described electric connectors more closely cooperate, thereby the removal force of dismounting taking and holding device 7 is increased, cause taking and holding device 7 not to be drawn out easily, at this moment, can extract smoothly for making taking and holding device 7, other at least one finger of this limit hand of operator will press the end of described base portion 71 away from operating portion 74, producing a horizontal component Fx ' opposite, and produce a downward vertical component Fy ' with component Fx direction.So, when the hook part 76 at taking and holding device 7 two ends detaches in the groove 66 of insulating body 61 in succession, because the retardance of effect of inertia and people's nervous system reaction, the end that described taking and holding device 7 is provided with operating portion 74 can continue to rotate obliquely, an end that is not provided with operating portion 74 then can continue oblique rotation down, so being provided with the holding part 75 of an end of operating portion 74, described taking and holding device 7 do not run into described terminal conduction region 64 possibly, conducting terminal 65 in the particularly described terminal conduction region 64, cause conducting terminal 65 to damage, and then influence the good serviceability of electric connector 6.
Therefore, be necessary existing electric coupler component is further improved.
