Fig. 2 is the three-dimensional exploded view of the utility model electronic card coupler.

[embodiment]

See also shown in Fig. 1,2, the utility model electronic card coupler 1 comprises insulating body 10, plurality of conductive terminals 20, a pair of retaining sheet 30 that is installed on insulating body 10 both sides, switch terminal 40 and lid 50.

Insulating body 10 roughly is flat tabular with the plastic material moulding, and it comprises that being provided with some first of conducting terminals 20 of accommodating accommodates that conduit 13, second is accommodated the base portion of conduit 14 and switch terminal first support slot 101 (not label) and the

retaining edge

11,12 and 17 of the protrusion that forms respectively from three sides of described insulating body base portion.Retaining edge 17 parts stretch out and form a rectangle end 171, and these rectangle end 171 upper surfaces are provided with two square aperture grooves 1711, and the middle part of one side is provided with switch terminal second support slot 1712.First accommodates conduit 13 and second accommodates the both sides that conduit 14 symmetries are positioned at base portion, and two accommodate and are respectively equipped with caulking groove 131 and 141 in the conduit.Dig respectively near the position at middle part with the base portion intersecting area at retaining

edge

11 and 12 and to be provided with depressed part 15 and 16, keep off

edge

11,12 simultaneously and be respectively arranged with the slit 110,120 of locating retaining sheet 30 in the corresponding position that forms depressed part 15,16.

Conducting terminal 20 all has the weld part 24 of reaching the electrical contact site that contacts 21 with electronic cards and being welded in circuit board, weld part 24 is to be extended to form by fixed part 23 bending downwards, wherein fixed part 23 both sides stretch out and are provided with inlay 231, and kink 22 links to each other with contact site 21 and fixed part 23 respectively.After conducting terminal 20 was assembled in corresponding terminal accommodating conduit, fixed part 23 was contained in the support that is subjected to the conduit inner platform behind the conduit, and the inlay 231 of its both sides embeds and conducting terminal cooperated with insulating body 10 stablize simultaneously.

Retaining sheet 30 is mounted in the slit 110 and 120 that forms on the insulating body 10 retaining edge, it comprises that one has holding section 31, horizontal part 32 and the connecting portion 33 of leg, via connecting portion 33 holding section 31 and horizontal part 32 are fused, described retaining sheet 30 assembling backs and the insulating body 10 common card receiving spaces that form, by the block positioning function of retaining edge and retaining sheet 30 on the insulating body 10, make the electronic cards of insertion realize that with conducting terminal excellent electrical property contacts.

Switch terminal 40 comprises first switch terminal 41 and second switch terminal 42, first switch terminal 41 is provided with the holding body 411 that is " H " type, the mid portion of holding body 411 stretches out and forms first leg 412 and first elastic contact part 413, second switch terminal 42 is provided with the holding section 421 that is T-shape, and holding section 421 stretches out and forms second leg 422 and second elastic contact part 423.
