Abstract

An electronic card connector comprises an insulating body, conductive terminals, a card eject mechanism, a head plate and housing. The card eject mechanism comprises a slide block with an extruder, a connecting rod and an elastic body. Both ends of the head plate can lean against the extruder on the slide block. The head plate surface provides symmetric projections clamped with pressure spring leaves on the housing. Front ends of the conductive terminals are pre-installed into terminal through holes between front and rear surfaces of the head plate. When being plugged into a corresponding electronic card, front edge of the electronic card pushes the pressure spring leaves to go upward, so that clamping between the head plate projections and pressure spring leaves disappears, and the head plate moves backward. The conductive terminals inside can merge and reach the holes on the electronic card, so that electrical connection can be fulfilled between the electronic card and the conductive terminals. Therefore, the head plate cannot move in case of a non-corresponding electronic card being plugged into. The configuration can not only prevent electronic cards from damaging conductive terminals because of faulty plugging, but also maintain parallelism between conductive terminals in order to ensure perfect electrical connection.

Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, refers in particular to a kind of electronic card coupler of mispluging of preventing.

[background technology]

Along with popularizing of electronic products such as digital camera, mobile phone, PDA, the use of memory card is also more and more, the specification type of card is also very many, as SD Card (SD), Compact Flash Card (CF), Smart Media Card (SM), Memory Stick (MS) and xD-Picture Card (XD) or the like, the CF card is as the storage card that occurs the earliest, and price comparison is low, so the popularity rate of using is also higher.The contact terminal of present employed CF card is positioned at the anterior of card and is housed in electronic cards inside, the front end of CF card is two socket holes, contact terminal just is housed in the described jack, and the contact terminal that the conducting terminal of CF card connector will touch electronic cards must be aimed at and could realize in the jack that is inserted into electronic cards electrically connecting.Therefore, the conducting terminal of CF card connector also is to be located at side by side in the card connector insulating body, and is the terminal base that needle-like is convexly equipped with out insulating body, when inserting the CF card, if firmly too big or improper then being easy to of plug-in card can not be used the conducting terminal bending.

The prior art relevant with the utility model can be consulted the novel patent application case in Taiwan No. 93202139, this patent has disclosed a kind of CF card connector, it comprises: insulating body and plurality of conductive terminals, described insulating body is made up of a fixed mount and adjustable shelf, the plurality of conductive terminals front end is located in the terminal through-hole of fixed mount in advance, adjustable shelf is provided with the terminal hole of corresponding conducting terminal, described adjustable shelf and fixed mount are respectively equipped with the guide channel and the tongue that can cooperatively interact, the front end both sides of adjustable shelf are connected with spring respectively with both sides, fixed mount rear end, when the CF card inserts its preceding end in contact adjustable shelf, adjustable shelf is pushed backward and compressed spring, terminal in the adjustable shelf is exposed reach to electrically conduct with the CF card; And when the CF card was extracted out, under the booster action of spring, adjustable shelf was got back to original position, and terminal is got back in the terminal hole of adjustable shelf, can protect terminal can not damage because of external force directly contacts.Yet, when mistake is inserted into the electronic cards of other type in the CF card connector, because electronic cards type difference and can not make the stressed improper distortion that bends of conducting terminal easily with the conducting terminal corresponding matching of card connector.

In order to address the above problem, some electronic card coupler is provided with misplug prevention device, correlation technique can be consulted Chinese utility model patent and be announced CN 2490729Y number, this patent has disclosed a kind of electronic card coupler, the electronic cards that is used for being provided with an end oblique angle is electrically docked, comprise that insulating body, group are located at conducting terminal in the insulating body, cover shielding casing and anti-mis-insertion member in insulating body and conducting terminal periphery, described anti-mis-insertion member comprises a crimping shell fragment and the barrier sheet that can move with the crimping shell fragment.When electronic cards was correctly inserted, the oblique angle of electronic cards leading edge pressed down the crimping shell fragment and barrier sheet is moved down, and electronic cards is able to smooth grafting; And when the electronic cards mistake was inserted, the lateral margin of electronic cards then offseted with barrier sheet and is difficult to insert, thereby preventing that electronic cards from pegging graft because of mistake damages conducting terminal.Yet existing electronic cards kind is more and more, and the frequency that people use electronic cards to insert, extract electronic card coupler only has a kind of needs of protecting structure can not satisfy actual use also in continuous increase.

Therefore, be necessary existing electronic card coupler is improved so that electronic card coupler has the better protection function.

[utility model content]

The purpose of this utility model is to provide a kind of electronic card coupler that prevents to misplug and can keep the conducting terminal depth of parallelism.

The purpose of this utility model is achieved through the following technical solutions: a kind of electronic card coupler; in order to electrically to dock with corresponding electronic cards; comprise insulating body; group is located at the conducting terminal in the insulating body; be used for protecting the push plate and the shielding casing of terminal; described insulating body comprises rear wall and sidewall; being provided with electronic cards in sidewall accommodates; described push plate is located at the place ahead of conducting terminal in advance; push plate is provided with some and the corresponding terminal through-hole of conducting terminal; described shielding casing roof is provided with some crimping shell fragments, and described push plate upper surface is provided with and the crimping shell fragment projection of buckle mutually.When not inserting electronic cards, under elastomeric effect, the conducting terminal front end is hidden in the push plate with the protection conducting terminal; When inserting corresponding electronic cards, this electronic cards leading edge pushes the crimping shell fragment and makes it upwards to lift, thereby the projection of push plate and the buckle of crimping shell fragment are disappeared, electronic cards pushes push plate and moves to direction of insertion together, at this moment, conducting terminal passes push plate, and to stretch out in push plate outer and continue to extend in the jack of electronic cards, and utilize trip mechanism that electronic cards is pinned, and the jack of electronic cards contacted with conducting terminal form electric connection; And when the electronic cards of non-correspondence is inserted, the buckle of the projection of push plate and crimping shell fragment disappears not can complete obiteration, push plate can not move, so be provided with, both can prevent that electronic cards from pegging graft because of mistake damages conducting terminal, can keep the depth of parallelism between conducting terminal again, reach excellent electrical property and connect.

Compared to prior art, the utility model electronic card coupler push plate upper surface is provided with and the shielding casing crimping shell fragment symmetrical projection of buckle mutually, can prevent that electronic cards from because of the mistake grafting damages conducting terminal, can keep the depth of parallelism between conducting terminal again, reach excellent electrical property and connect.
