Continuation is referring to Fig. 2 and in conjunction with shown in Figure 3, during insulating body 10 moulding, be one-body molded with at least two group electric terminals and first flexible terminal 21 and second terminal 22, these insulating bodies 10 are formed by central dividing plate 11 has first receiving space 111 and second receiving space 112 that two different directions insert.Constitute and to have the first side wall 12, second sidewall 13, the 3rd sidewall 14 and the 4th sidewall 15 between accommodating, on second sidewall 13, be provided with a hollow-out parts 16 to dividing plate 11 near the 3rd sidewall 14, these hollow-out parts 16 are convenient to first flexible terminal 21 and second flexible terminal, 22 front ends are ccontaining, be provided with the hollow out chute 114 of chute 113 and perforation dividing plate 11 side by side near the 3rd sidewall 14 places at dividing plate 11, be provided with chute 141 in the 3rd sidewall 14 in addition, chute 113 is provided in the 3rd terminal 60 and slides, and other two chutes structure then is provided in slide block 30 operations.

First flexible terminal 21 and second flexible terminal, 22 structures are basic identical, be fixed on insulating body the 3rd sidewall 13 and extension in hollow-out parts 16, its concrete structure as shown in Figure 4, by edge-on main leaf 211,221 front ends extend shake-up arm 212,222, these two shake-up arms 212,222 bendings are to be in opposite directions and bending when forming, form a mouth-clamped type structure, each touches arm 212,222 upper punches are provided with contact site 213,223, two contact sites 213,223 clearance distance is less than the thickness of the 3rd terminal 60 inserted terminals 61, so that two contact sites 213,223 all can contact with the inserted terminal 61 of the 3rd terminal 60; Outside horizontal Zhang Shenzai vertically bends out a changeover portion 214,224 in edge-on main leaf 211,221 tail end bottom edge, and does not hold formation welding ends 215,225 in changeover portion.

20 of trip mechanisms are by slide block 30, connecting rod 40 and spring 50 constitute, in the present embodiment, only slide block 30 is specifically addressed explanation, as Fig. 2 and shown in Figure 5, main piece 31 in the middle of slide block 30 has one, middle main piece 31 has a broad gauge road 311, continuous respectively edge-on projection 32 and the flat projection 33 of being connected to of main piece 31 two side faces front ends in the centre, edge-on projection 32 outer side surfaces are provided with the rail groove 321 of doing motion for connecting rod 40, and on flat projection 33 walls 331, offer groove 332, in groove 332, be provided with one group of through hole 333 that runs through flat projection 33 side by side, described groove 332 is provided in 60 grafting of the 3rd terminal with through hole 333 and fixes, and flat projection 33 walls 331 opposite face front ends have a tail end 34, but these tail end 34 holdings the 3rd terminal 60 front ends, to prevent run-off the straight, has the inclined-plane 35 of promotion in flat projection 33 rear ends.

The 3rd terminal 60 structures are also comparatively simple, and 60 assemblings of the 3rd terminal are fixed in slide block 30 grooves 332.Have inserted terminal 61 and back stiff end 62 before one, extend in stiff end 62 downside appropriate locations and convex with the fixed part 63 at a stalemate, and be provided with wedge mouth 64 at a stalemate with corresponding through hole 333.

Become these card connector 100 arrangement for detecting by last concrete described insulating body 10, first flexible terminal 21 and second flexible terminal 22, trip mechanism 20 and the 3rd terminal 60 are just capable of being combined.Card connector 100 each assembly are installed on the insulating body 10, electronic cards 200 is pressed Fig. 6 (for ease of explanation, not shown metal clamshell 80 down during plug-in card) direction is inserted in second receiving space 112 shown in, electronic cards 200 side skew walls 201 touch and are against on slide block 30 inclined-planes 35, as shown in Figure 7, slide block 30 is in electronic cards 200 effect

lower edge chutes

141 and 114 forward end operations, when the 3rd terminal 60 is assembled in slide block 30 grooves 332, its the 3rd terminal 60 lateral edges 65 are a little more than the wall 331 of flat projection 33, the 3rd terminal 60 retinue slide blocks 30 are done to move together, and move to previous crops along chute 113; When electronic cards 200 insertions put in place, inserted terminals 61 just in time insert in 223 gaps of leaving of contact site of the contact site 213 of first flexible terminal 21 and second flexible terminal 22 before the 3rd terminal 60, first flexible terminal 21 and second flexible terminal 22 are as the mouth-clamped type structure, inserted terminal 61 two side faces fully contact (as shown in Figure 8) with contact site 213 with contact site 223 respectively before making the 3rd terminal 60, to form the arrangement for detecting structure, realize the data access reading.When electronic cards 200 application of forces, under trip mechanism 20 effects, slide block 30 drives the 3rd terminal 60 and replys original position again, and the 3rd terminal 60 breaks away from and first flexible terminal 21 and second flexible terminal 22.

By above-mentioned explanation, the running mechanism of the utility model card connector arrangement for detecting is very simple as can be known, fix one the 3rd terminal 60 by trip mechanism 20 installings, utilization is moved back two flexible terminals that set firmly on card operation principle and the insulating body 10 and is contacted, these flexible terminals with the mouth-clamped type structure can be firm 60 clampings of the 3rd terminal are contacted, can reach more stable detecting effect, further the stability of electron gain card use.

Be familiar with enforcement utility model purpose and the effect that this operator understands the utility model spirit strictly according to the facts for making, for embodiment and accompanying drawing only be that the utility model is illustrated, not to the utility model any restriction in addition, the utility model still can have other variation execution mode, so allly be familiar with this operator and carry out other pattern under this case utility model spirit and implement not breaking away from, the equivalence that all should be considered as this case claim is implemented.
