Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, refers to a kind of electronic card coupler for the plant of plurality of specifications memory card especially.

[background technology]

General known electronic card coupler, be subjected to most user's welcome with the All-in-One electronic card coupler, its reason is that the All-in-One electronic card coupler can use for inserting the dissimilar memory card of most kinds, as SD (Secure Digital) card, MS (Memory Stick) card, XD (Extreme Digital) card etc., the user need not buy multiple connector can use multiple memory card.

Yet, because the All-in-One electronic card coupler generally all comprises the terminal group of docking with different electronic cards of arranging more, when inserting the electronic cards of docking, tend to collide the terminal group (is preceding with insertion end) at front row with back row's terminal group, cause front-seat terminal group distortion, and easily cause short circuit.In order to solve this kind problem, for example United States Patent (USP) discloses a kind of All-in-One electronic card coupler No. 6641413.

Described All-in-One electronic card coupler comprises an insulating body, is contained in a first terminal group and one second terminal group, a sliding component and a resetting device of described insulating body, is inserted by insertion end and docks with corresponding terminal group for two kinds of dissimilar electronic cards C1 and electronic cards C2.Described the first terminal group is contained in the front end (is preceding with insertion end) of described insulating body, and described second terminal group is contained in the rear end of described insulating body.Each terminal of each described terminal group comprises a weld part, a contact site, and a junction that connects described weld part and described contact site.Described sliding component has one first resettlement section, one first stopper section of being located at front end; Be located at one second resettlement section, one second stopper section of rear end, and be located at a tabular press section that is provided with near rear, described first stopper section.When not inserting any described electronic cards, the press section of described sliding component presses on its below with the termination contact portion of described the first terminal group, when the SD card C1 that docks with described the first terminal group inserts, its side is contained in described first resettlement section of described sliding component, leading edge is against described first stopper section, so promote described sliding component backward slippage can not advance until being subjected to described insulating body backstop.

Simultaneously, along with moving behind the described press section, the contact site of described the first terminal group exposes, thereby can contact with the contact of the SD card C1 that inserts.When a MS card C2 inserts, its width is narrow and directly enter described second resettlement section than SD card C1, leading edge is against described second stopper section, and then promote described sliding component backward slippage until by described insulating body backstop, and contact with the termination contact portion of described second terminal group, because MS card C2 directly crosses described press section when inserting, thus described the first terminal group can not collided, so need not to worry the terminal distortion of described the first terminal group.

In addition, the described sliding component of described existing All-in-One electronic card coupler and described resetting device start along with the spring of described resetting device is compressed in the propelling of described electronic cards, are played the driving member effect of described resetting device together.

This electronic card coupler design defect is: described All-in-One electronic card coupler on the surface, though solved the short circuit problem that the electronic cards that matches with back row's terminal group is planted and may be caused, can not cause collsion damage to front-seat terminal group yet, but, in fact because the contact site of front-seat terminal group is in the state of stressed extruding always, easilier cause front-seat terminal group elastic fatigue and permanent deformation, can't closely contact with the described electronic cards that cooperates, cause electrically connect unstable.

Therefore, be necessary to design a kind of new electronic card coupler, to address the aforementioned drawbacks.

[utility model content]

The purpose of this utility model is to provide a kind of preventing because of what the electronic cards plant caused described front-seat terminal to be caused short circuit, and there is not the electronic card coupler of the problem of stressed extruding in front-seat terminal group.

In order to achieve the above object, the utility model electronic card coupler, comprise: an insulating body, it has a receiving space of planting with for described electronic cards, described receiving space one end is provided with an openend, offer one first slide rail and connect one second slide rail of described first slide rail at the inner corresponding described receiving space of at least one side of described insulating body, described first slide rail is near described openend, and described second slide rail is lower than described first slide rail; One slippage pedestal, it is installed in the described receiving space, and described slippage pedestal has a plug-in card space, bottom, described plug-in card space is provided with a through hole and is communicated with described receiving space, and be provided with at least one guide pillar at least one outside of described slippage pedestal, described guide pillar be slidingly matched described first slide rail and described second slide rail are provided with the described electronic cards that a stop section correspondence is alternatively inserted different size at least one inboard place of described slippage pedestal; And the two-terminal group is installed on respectively in the described insulating body at least, and each described terminal group is respectively equipped with most terminals, in the described terminal group, at least one described terminal has a docking part and enters described receiving space, the described docking section of each of described terminal group cooperates wherein each described contact site configuration specification of a described electronic cards, and the described docking section of wantonly two different described terminal group in described receiving space according to being of described openend apart from distance before and after dispose; When a selected described electronic cards enters described plug-in card space and abuts to described stop section, at least one contact site of described electronic cards just between described openend and the predetermined described docking section that connects, and is crossed the docking section of other the described terminal group between described openend and the described docking section of being scheduled to connect along approach axis.

Compared with prior art, it is by establishing two sections slide rails with difference in height in described insulating body both sides, and further be provided with can slippage on described two sections slide rails described slippage pedestal, its beneficial effect is:

1. the described slide rail position relative fixed of the described guide pillar on the described slippage pedestal on described insulating body can prevent plug-in card, described electronic cards produces and beats or get loose when moving back card in described plug-in card space.

2. when described electronic cards and front-seat terminal group connect, in the raw, there be not any contact in described electronic cards with back row's terminal group to described back row's terminal group, and is not subjected to any extruding when non-butt joint, electrically connect and stablize, improved product overall performance and life-span.
