The taking and holding device of electric connector
[technical field]
The utility model is the taking and holding device about a kind of electric connector, especially refers to a kind of taking and holding device that picks and places the electric connector that electric connector uses for the vacsorb device.
[background technology]
Electric connector is to draw by the vacsorb device correctly to be positioned on the circuit board, yet, electric connector can have many through holes for the surface of absorption, and the suction nozzle that can not directly utilize the vacsorb device adsorbs this electric connector, so generally button is held taking and holding device on electric connector, thereby comes mobile electric connector by drawing this taking and holding device.Relevant prior art of the present utility model sees also Fig. 1, this taking and holding device is a layer of transparent film 3, this film 3 is covered on electric connector 4 surfaces, the suction nozzle of vacsorb device comes mobile electric connector 4 by drawing film 3, yet because electric connector 4 middle positions are equipped with through hole (among the figure shown in the fine line), so need to use the film 3 of big thickness that the suction nozzle absorption of sufficient intensity for the vacsorb device is provided, cost is improved.
See also Fig. 2, be another related art, taking and holding device 5 is a plastic material, its middle section is provided with two through holes 51, contiguous through hole 51 positions, these taking and holding device 5 bottom surfaces are respectively equipped with along the elastic arm (not shown) of through hole 51 lengthwises to extension, and this elastic arm is clasped mutually with electric connector 6.Though material cost has been saved in this kind design, but because these taking and holding device 5 surfaces are provided with two through holes 51, so determined maximum inscribed circle A area is the spendable maximum area of suction nozzle of vacsorb device between these two through holes 51, so then define the spendable area of suction nozzle, and make the position of suction nozzle and dimension precision requirement higher, there is operate miss promptly may cause picking and placeing the adverse consequences of inefficacy slightly.
[summary of the invention]
The purpose of this utility model is to provide a kind of can save cost, and can effectively increase the taking and holding device of the electric connector of the area of drawing for the vacsorb device.
The purpose of this utility model is achieved in that the taking and holding device of this electric connector is provided with a plate-like body and film.Electric connector is provided with lid, the lid middle position is provided with a square through hole, regional parallel two through holes that run through body that are provided with of body center, body is respectively equipped with elastic arm near the contiguous through hole of the side position of electric connector, and this elastic arm is used for being clasped with the through hole of electric connector.Film system is covered on body surface, and covers two through holes of body.
Compared with the prior art, the utlity model has following advantage: because of film covers two through holes of body, so body all can supply vacsorb device suction operation away from the complete area of the side of electric connector.

[embodiment]
See also Fig. 3 to Fig. 5, electric connector 1 is provided with pedestal 11, lid is connected on the pedestal 11 and the lid 12 of pedestal 11 slips relatively, these lid 12 middle positions are provided with a square through hole 121 that runs through lid 12, it has four madial walls 1211, and wherein two parallel mutually madial walls 1211 form square buckling groove 122 near recessed lid 12 certain depths of an end of pedestals 11 certainly.
The taking and holding device 2 of electric connector comprises body 21 and film 22, this body 21 posts and is installed on the electric connector 1, it is a rectangular plate shape, be provided with bottom surface 211 near electric connector 1 one sides, the middle section of body 21 is provided with the two mutual parallel L shaped through holes of offering 212,211 contiguous through holes, 212 positions, bottom surface are provided with elastic arm 213 along through hole 212 lengthwises to extending respectively, and these two elastic arms, 213 tops relatively outwards projection are provided with Access Division 2131.See also Fig. 6, when body 21 and lid 12 buttons were held, the Access Division 2131 of body 21 elastic arms 213 was clasped with the buckling groove 122 of lid 12.
See also Fig. 7 and Fig. 8, body 21 engages with the elasticity of through hole 121 by elastic arm 213 and is installed on (as shown in Figure 6) on the electric connector 1, is covered on body 21 surfaces with layer of transparent film 22 then, and this film 22 covers two through holes 212 of body 21.Body 21 is generally plastic material, it has the advantage that cost is low and intensity is high concurrently, in addition, after film 22 covers through hole 212 (among the figure shown in the fine line), can can be extended to the side of whole body 21 for the operations area of vacsorb device absorption, and then can prevent to cause the problem that electric connector 1 lost efficacy that picks and places because of the scale error of suction nozzle.
Selecting for use of relevant film 22 in this embodiment, only need be used to cover through hole 212 than the small size material and get final product, and need not to possess bigger intensity and optional very thin material, this small size and selection standard as thin as a wafer, all escapable cost.
