like locating piece

36, and 38 both sides, stopper section in locating piece 36 the place aheads protrude out downwards respectively and form spacer 37.Connecting portion 35 is from the downward-sloping extension of pressure section 31 left ends, and the width of connecting portion 35 makes the rear end of banking stop 34 form scarce piece less than the width of pressure section, and connecting portion 35 horizontal-extending backward forms stopper section 38.

See also Fig. 5 and Fig. 6, first conducting terminal 50 is inserted in respectively in the first terminal groove 14 of first card slot 11, and second conducting terminal 60 is contained in respectively in second terminal groove 15 of second card slot 12.Keeper 30 is contained in the location notch 20, compressing sheet 32 wears and is positioned at pressing plate 18 belows and is replaced downwards by pressing plate 18, and compress the end face of the left side wall 26 of the front end of sheet 32 and second card slot 11, banking stop 34 is contained in the stopper slot 23, and the formed scarce piece in banking stop 34 rear ends is replaced the rear wall of stopper slot 23.Connecting portion 35 is resisted against the top of supporting plate 30, and stopper section 38 is inserted the left end of location notch 20 and is positioned at the below of base plate 17, and the locating piece 36 of stopper section 38 protrudes out in the location hole 21 that is positioned base plate 17.

See also Fig. 7, the perforate 44 of the forward and

backward side plate

42,43 of loam cake 40 respectively with insulating body 10 on fixedly projection 28 corresponding fastenings, so far, the utility model electronic card coupler 100 assembling is finished.

See also Fig. 8 and Fig. 9, when the utility model electronic card coupler 100 uses, first electronic cards 70 is inserted first card slot 11 of insulating body 10, and the upper surface of first electronic cards 70 is lower than base plate 17 planes of second card slot 12, the left side of first electronic cards 70 compresses the lower surface of sheet 32 front ends and the upper surface flush of first electronic cards 70 against the left side wall 26 of first card slot 11.At this moment, stir the pushing piece 33 of keeper 30 to the right, locating piece 36 skids off and slides against the lower surface of base plate 17 in location hole 21, along with pushing piece 33 further slides to the right, compressing sheet 32 skids off from pressing plate 18 lower ends, because of compressing the lower surface of sheet 32 front ends and the upper surface flush of first electronic cards 70, thereby compress that sheet 32 skids off pressing plate 18 and slide and withhold in the upper surface of first electronic cards 70 along the upper surface of first electronic cards 70, connecting portion 35 tilts to connect pressure section 31 and stopper section 38, base plate 17 is upwards replaced in the rear end of stopper section 38, connecting portion 35 compresses sheet 32 and makes that compressing sheet 32 replaces pressing plate 18 to upper support, thus, pressing plate 18 is upwards replaced to react on and is compressed sheet 32 and apply downward pressure because of compressing sheet 32, make to compress the upper surface that sheet 32 firmly compresses first electronic cards 70 that first electronic cards 70 is compressed sheet 32 and compresses and fix.At this moment, spacer 37 front ends are replaced the rear end face of supporting plate 13 and are limited keeper 30 and further travelled forward, and locating piece 36 skids off base plate 17 lower surfaces and protruding being exposed in the location notch 20, and banking stop 34 rear portions still are positioned at stopper slot 23.

See also Figure 10, second electronic cards 80 is inserted second card slot 12, the right-hand member of second electronic cards 80 slips over the upper surface of first electronic cards 70 and is covered on and is staggered stacked above first electronic cards 70, thus, the right-hand member of second electronic cards 80 is positioned at the top of first electronic cards 70 and first electronic cards 70 is covered fully.

When need take out first electronic cards 70, can take out second electronic cards 80 earlier, thereby 70 protruding exposing of first electronic cards, stir pushing piece 33 more left, make the stopper section 38 of keeper 30 slide left, the locating piece 36 of stopper section 38 is replaced the lower surface of second card slot, 12 base plates 17, slipping into location hole 21 until locating piece 36 also is sticked in the location hole 21 location, at this moment, the front end that compresses sheet 32 slip away first electronic cards 70 upper surface and be retracted into fully pressing plate 18 the below and with the end face of the left side wall 26 of first card slot 11, thereby, first electronic cards 70 is not subjected to the power that the compresses effect of spacer 30, at this moment, can make things convenient for first electronic cards 70 in first card slot 11, to withdraw from.

In sum, the utility model electronic card coupler 100 is fastened on first electronic cards, 70 upper surfaces and withholds first electronic cards 70 fixing by the sheet 32 that compresses of keeper 30, thereby, second electronic cards 80 can not make the electronic cards 70 of winning slide in first card slot 11 because of the friction effect of second electronic cards 80 when inserting and slipping over the upper surface of first electronic cards 70, first electronic cards 70 can be therefore not influenced and loosening yet, avoid first electronic cards 70 to depart from electrical contact position, and when first electronic cards 70 is subjected to applied external force, still can not depart from electrical contact position, thereby guarantee reliable and stable electric connection between first electronic cards 70 and the external circuit, to realize stable signal transmission.
