Abstract

The utility model relates to an electronic card connector. The outside of a supporting arm of an insulating base is dented with a guide slot, wherein a push handle is arranged in the guide slot. The front end of the push handle is provided with a connecting rod pivoted on the insulating base. The top wall of the other end of the connecting rod is just butted on the rear edge of an ejecting component arranged on another position of the insulating base. Therefore, the push handle can be pushed to drive the connecting rod to pivotally rotate. A top arm of the connecting rod is used for pushing out the ejecting component, and top plates on both ends of the ejecting component are used for disengaging the electronic card. Besides, the inner face relatively to the two supporting arms of the insulating base is respectively provided with alignment mechanisms to align and limit the inserting direction of the electronic card.

Description

Electronic card coupler

The utility model is relevant a kind of electronic card coupler, refers to a kind of have the card effect of moving back of the even application of force and the electronic card coupler to positive interaction that prevents wrong plug especially.

Present various digitalized electron product is as digital camera, PC etc., because the data that function and institute must store handle is more and more many, so all have additional the electronic cards device of the use of can pegging graft gradually.The electronic cards of using has less dimensions and less conducting end subnumber because it is pegged graft, therefore in the structure of the electronic card coupler of prior art, be not provided with any retreat-card device, but be concaved with bigger radian space at the opening part of electronic card coupler, directly grip electronic cards and insert or extract operation for the user.But this type of grips the electronic card coupler that electronic cards is carried out Plug Action voluntarily by the user; regular meeting suffers damage because of the improper or method fault of user's application of force; as the inserted terminal of conducting terminal because of discontinuity flexural deformation, the obstruction when causing insert electronic cards again next time and can't inserting smoothly.

On the electronic card coupler that other specification electronic cards are connected, because the conducting end subnumber is quite a lot of, the required contact engaging and separating force of electronic cards is bigger, so be provided with the structure of assisting to withdraw from electronic cards more, as Taiwan patent the 81216447th, 82205600,82216859,83107162, number and No. the 5149276th, 5152697,5286207,5324204,5421737,5470241,5492481 and 55076758, United States Patent (USP) etc.But the needed card strength of moving back of these electronic card couplers is bigger, and it is quite complicated that it moves back card, and be not suitable on the applied electronic card coupler of the utility model.

Because the related little and thin thickness of electronic cards size of this case, common people are not if add attention, be easy to hold electronic cards by mistake and the electronic cards reverse side is inserted, and the press-bending terminal takes place or the wrong plug terminal causes problems such as short circuit.There is partial monopoly that this situation is improved at present, as No. 5668365 patent of the U.S. etc., this patent mainly convexes with top stopping block on the plug surface appropriate location of electronic card coupler insulating body, the particular end angle of again electronic cards being inserted leading edge is made as oblique re-entrant angle, the end angle of not establishing oblique re-entrant angle when therefore the electronic cards reverse side inserts only will be blocked and can't be entered on top stopping block, remind the user to correct whereby.Yet this design is after electronic cards is inserted certain-length, and the user just can find the electronic cards wrong plug, therefore has the puzzlement that repetitiousness injects, extracts.

The purpose of this utility model is to provide a kind of and has uniform force application, can withdraw from the trip mechanism of electronic cards easily, and designs the electronic card coupler that aligns mechanism of restricted electronic cards direction of insertion.

The purpose of this utility model is achieved through the following technical solutions: a kind of electronic card coupler, include an insulating base frame, conducting terminal, push away handle, connecting rod, and member such as ejection piece, in the guide groove that the insulating base frame one supporting arm outside is arranged with, be equipped with and push away handle, push away the handle front end and be provided with the connecting rod that is articulated on the insulating base frame, and the top arm of the connecting rod other end just is resisted against the trailing edge of the ejection piece of being located at the insulating base frame another location, therefore can push and push away handle and make it drive connecting rod to pivot, and borrow its top arm that ejection piece is released and utilize the top plate portion at ejection piece two ends that electronic cards is withdrawed from.On the relative inner face of insulating base frame two supporting arms, respectively be provided with in addition and align mechanism, so that the function that aligns and limit the electronic cards direction of insertion to be provided.

Compare prior art, the utlity model has following advantage: it not only can borrow its even application of force to make to move back card motion more smooth, thereby prevent the user plug voluntarily electronic cards the infringement that may cause, and can allow the user notice that the certain surface that must correctly grip electronic cards could align insertion with electronic cards by means of aligning mechanism, damage terminal or cause system short-circuit thereby avoid the electronic cards reverse side to insert the back, to reduce the trouble of heavily covering insertion.
