Description

Electronic card coupler

The utility model relates to a kind of electronic card coupler, relates in particular to a kind ofly electronic cards and circuit board are electrically connected and to have the electronic card coupler of arrangement for detecting with the insertion state of detecting electronic cards.

Usually borrow an electronic card coupler to be electrical connected between electronic cards and circuit board, and whether some electronic card coupler also is provided with arrangement for detecting, insert fully in order to the detecting electronic cards.The prior art relevant with the utility model, as United States Patent (USP) the 5th, 013,255,5,334,034,5,370,544 and 6,004, shown in No. 155 grades.The arrangement for detecting of these prior aries generally includes one and moves a terminal and a fixed terminal, and originally be between mobile terminal and fixed terminal and contact/off-state, after electronic cards is inserted, compress mobile terminal by the electronic cards leading edge, make mobile terminal and fixed terminal become disconnection/contact condition, thereby realize whether the detecting electronic cards has been inserted into the final position.But United States Patent (USP) the 5th as described above, 334,034 and 5,370, shown in No. 544, could contact with fixed terminal reaching on-off action, thereby easily elastic fatigue take place in use for some time and can't return to initial condition to match with fixed terminal because the mobile terminal of these existing structures need produce bigger deflection, and it is comparatively complicated that it compresses arm configuration, is unfavorable for making.

The purpose of this utility model is to provide a kind of electronic card coupler with arrangement for detecting, and wherein this arrangement for detecting is convenient to make and anti-aximal deformation value, thereby can increase life of product and save cost.

The purpose of this utility model is achieved through the following technical solutions: the utility model electronic card coupler, comprise insulating body, be housed in conducting terminal and arrangement for detecting in the insulating body, wherein the arrangement for detecting group is located on the insulating body, comprise flexible terminal and fixed terminal, and flexible terminal is provided with elastic arm, own elasticity arm one end is the linking arm of forked extension and compresses arm, and compress the oblique setting of arm own elasticity arm one end and the certain distance that interlaces, fixed terminal then comprises group connecting part and afterbody, when electronic cards is inserted toward arrangement for detecting one end by slot one end, the electronic cards leading edge compresses the elastic arm of flexible terminal, make the arm that compresses of flexible terminal move and electrically connect, whether insert fully with the detecting electronic cards with fixed terminal along the electronic cards direction of insertion.

Compared to prior art, the elastic arm of the flexible terminal of the utility model electronic card coupler arrangement for detecting and compress the certain distance that interlaces between the arm, when electronic cards compresses elastic arm, compressing arm only need move very little distance and can contact with the group connecting part of fixed terminal, thereby the difficult elastic fatigue that produces, and flexible terminal adopts vertical assembling mode with fixed terminal on insulating body, also can save to take up room.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is an arrangement for detecting stereogram of the present utility model.

Fig. 3 is a three-dimensional combination figure of the present utility model.

Please refer to Figure 1 and Figure 2, the utility model electronic card coupler 1 comprises insulating body 10, conducting terminal 20, arrangement for detecting 30 and write-protect terminal group 40.Wherein insulating body 10 comprises diapire 101, the first side wall 102 and second sidewall 103, and diapire 101 is provided with the terminal containing slot 105 that plural number runs through its upper and lower surface, and be formed with slot 104 between described diapire 101 and two sidewalls 102,103, and be provided with first retaining wall 106 and second retaining wall 107 at slot 104 front ends.First retaining wall 106 comprises mutual vertically disposed vertical blocks 108 and horizontal block 109, offers first accepting groove 110 in the middle of the vertical blocks 108, and is provided with first opening 111 at vertical blocks 108 front surfaces.In addition, horizontal block 109 and between the rectangular block 115 of slot 104 front center, be formed with second accepting groove 112 and second opening 113.The first side wall 102 middle parts are provided with breach 114 simultaneously, in order to accommodate write-protect terminal group 40.

In 20 groups of terminal containing slots 105 that are located on the insulating body 10 of conducting terminal, which is provided with contact site 201 and weld part 202, wherein contact site 201 protrudes from the upper surface of insulating body 10 diapires 101, and weld part 202 then can be welded on the circuit board (not shown).

Arrangement for detecting 30 is made up of flexible terminal 301 and fixed terminal 307, wherein flexible terminal 301 is provided with elastic arm 302, own elasticity arm 302 1 ends are the linking arm 303 of forked extension and compress arm 304, and linking arm 303 1 ends are provided with holding parts 305, and holding parts 305 1 ends also bend and are extended with afterbody 306.In addition, describedly compress the oblique at an angle extension of arm 304 own elasticity arms 302 1 ends, make compress arm 304 terminal with the elastic arm 302 free ends certain distance that interlaces; 307 of fixed terminals comprise group connecting part 308 and the afterbody 309 that extends from the bending of group connecting part one end.

Please refer to shown in Figure 3ly, during assembling, the holding parts 305 of flexible terminal 301 is retained on the insulating body 10 in first accepting groove 110 on first retaining wall 106, and 306 of afterbodys pass first opening 111 and are welded on the circuit board.The group connecting part 308 of fixed terminal 307 is retained in second accepting groove 112 between first retaining wall 106 and the rectangular block 115, and 309 of afterbodys pass second opening 113 and are welded on the circuit board.

In the present embodiment, when electronic cards (not shown) was not inserted toward the insertion of arrangement for detecting 30 directions fully by slot 105 1 ends, the arm 304 that compresses of flexible terminal 301 did not contact with the group connecting part 308 of fixed terminal 307; And when electronic cards was inserted fully, the electronic cards leading edge compressed the elastic arm 302 of flexible terminal 301 earlier, and flexible terminal 301 activates and compresses arm 304, the group connecting part 308 that compresses arm 304 and fixed terminal 307 is electrically connected, thereby whether the detecting electronic cards was inserted fully.Yet, also can omit fixed terminal 307, when electronic cards was inserted fully, the electronic cards leading edge compressed the elastic arm 302 of flexible terminal 301, make flexible terminal 301 compress arm 304 directly with circuit board on corresponding electronic circuit (not shown) electric connection.
