Embodiment

See also Fig. 1 to Figure 10, a kind of electronic card coupler with terminal protecting function, it comprises a housing 1, a whirligig 2, one group of the first terminal 3, one group of second terminal 4.

This housing 1 comprises a pedestal 12, a loam cake 14.

This pedestal 12 comprises a rear wall 124, one left wall 126, the one right wall 128 that is connected.

The middle part of this rear wall 124 vertically convexes with a rear platform 129 forward, offers some the first terminal slots 127 side by side on this rear wall 124 above rear platform 129.Surround between this left side wall 126, right wall 128 and the rear platform 129 and form one first electronic cards tank 130.

Below rear platform 129, offer some second terminal slots 132 side by side on this rear wall 124.

Platform 138 before between the front end of this left side wall 126, right wall 128 sustained height that should rear platform 129 being provided with one.Be an opening 139 between platform 138 and the rear platform 129 before being somebody's turn to do.Platform 138 and both sides respectively offer the chute 137 of the thickness of a corresponding SD card and mmc card before being somebody's turn to do near this left side wall 126, right wall 128 places.

Vicinity should respectively offer a groove 135 in preceding platform 138 places on this left side wall 126, the right wall 128.

The two ends that this loam cake 14 is metallic plates are stamped to form vertically downward, and it covers above this pedestal 12.

This whirligig 2 is swivel plates, and it comprises a plate body 22, and each vertically is provided with a left plate 24, a right plate 26 left and right sides edge of this plate body 22.These plate body 22 upper surfaces are provided with some terminal containing slots 222 side by side.This plate body 22 is provided with some ejection pieces 223, and these some ejection pieces 223 are located at respectively in this terminal containing slot 222.On the internal face of this left plate 24 and right plate 26 left wall 126 that should pedestal 12, the chute 137 of right wall 128 are respectively offered a chute 224.Each outwards is equipped with a projection 226 left plate 24 of this plate body 22, the leading section of right plate 26, and this two projection 226 is contained in respectively in the groove 135 of left wall 126, right wall 128 of this pedestal 12.

This first terminal 3 comprises a fixed part 32, and the contact site 34 of an arch is established in this fixed part 32 front ends bending extension.This fixed part 32 is planted and is fixed in the first terminal slot 127 of this rear wall 124.This contact site 34 is stretched in this first electronic cards tank 130, and near this electronic card coupler in the inner part, so this first terminal 3 can be used for electrically connecting narrow and thick relatively MS card 5.

This second terminal 4 comprises a body 42, and a fixed part 44 is established in the rear end extension of this body 42, and the front end of this body 42 upwards bending extension is established the contact site 46 of an arch.This fixed part 44 is planted and is fixed in second terminal slots 132 of this rear wall 124.This body 42 is located at the below of this rear platform 129, these contact site 46 correspondences are located in some accepting grooves 222 of plate body 22 of this whirligig 2, because second terminal 4 has elasticity, therefore these some second terminals 4 make this plate body 22 downward-sloping certain angles with this whirligig 2 to pressing down.The contact site 46 of this second terminal 4 is located at this electronic card coupler in the outer part, so this second terminal 4 can be used for electrically connecting wide and thin relatively SD card 6 and mmc card (figure does not show).

During installation, these some the first terminals 3 are installed in the first terminal slot 127 of this pedestal 12, these some second terminals 4 are installed in second terminal slots 132 of this pedestal 12; Then this whirligig 2 is installed in this pedestal 12, this two projection 226 is contained in respectively in the groove 135 of left wall 126, right wall 128 of this pedestal 12, plate body 22 can be in this opening 139 places rotation, and contact site 46 correspondences of second terminal 4 are located in some accepting grooves 222 of this whirligig 2, this second terminal 4 was pressed in the contact site 46 that makes this second terminal 4 on this ejection piece 223 and was in below the height of this rear platform 129 this moment; The top that then loam cake 14 is contained in this pedestal 12 gets final product.

When inserting short and wide SD card 6, this card body is along the left wall 126 of this pedestal 12, the chute 137 of right wall 128 injects, block then in the chute 224 that body enters the left plate 24 of this whirligig 2 and right plate 26, thereby this plate body 22 is pulled upwardly, in the process that this plate body 22 rotates up, the move upward downside of the body 42 that withstands on second terminal 4 of this ejection piece 223, therefore also corresponding the moving upward of this contact site 46 exceeds the height of this preceding platform 138, platform 138 at grade before this plate body 22 is with this, after this card body continuation was injected and put in place, the conducting strip on this SD card 6 (figure does not show) electrically contacted and conducting with the contact site 46 of second terminal 4.

Because this second terminal 4 has elasticity, therefore these some second terminals 4 make this plate body 22 downward-sloping certain angles with this whirligig 2 to pressing down, and the contact site 46 of this second terminal 4 is in below the height of this preceding platform 138.When inserting long and narrow MS card 5, this MS card 5 is thicker and narrow, therefore can not enter in the chute 224 of the chute 137 of this pedestal 12 and whirligig 2, this MS card 5 passes through from the top of this second terminal 4, after continuation is inserted and is put in place, conducting strip on this MS card 5 (figure does not show) electrically contacts and conducting with the first terminal 3, can not contact with second terminal 4.

In the utility model; pedestal 12 two sides are provided with chute 137; installed whirligig 2 in this pedestal 12; also be provided with chute 224 on the whirligig 2; when therefore inserting short and wide SD card 6; by chute 224 and chute 137 and whirligig 2 is pulled upwardly; therefore the conducting strip that is installed in the contact site 46 of second terminal 4 of whirligig 2 upper surfaces and SD card 6 contacts and electrically conducts; and when inserting long and narrow MS card 5; this MS card 5 electrically contacts and conducting with the first terminal 3 by the back from the top of this second terminal 4; do not contact with second terminal 4; realized the peg graft purpose of multiple electronic cards of a connector; and prevented that effectively bad second terminal 4 is in the outer part hung in collision when the electronic cards of inserting with in the inner part the first terminal 3 couplings (MS card 5), better protection the terminal of connector.
