Abstract

An electronic card connector comprises an insulation body, a conductive terminal which forms one body in the insulation body, a detection switch arranged on the insulation body and a metal shell which covers the insulation body. The insulation body, the conductive terminal and the metal shell form an accommodation space used for accommodating an electronic card. The detection switch comprises a first switch terminal arranged on a tail portion of the insulation body and a second switch terminal arranged on one side of the insulation body. The second switch terminal comprises first and second folding portions which are extended into the accommodation space. When the electronic card is inserted into the accommodation space, one side edge of the electronic card and a corner of a front end of the side edge correspondingly pushes the first and second folding portions respectively. Performance of the detection switch of the electronic card connector is stable.

Description

Electronic card coupler

Technical field

The present invention relates to electric connector field, espespecially a kind of electronic card coupler.

Background technology

Electronic card coupler is a kind of carrier for electronic cards such as accommodating identification card, storage cards, carries the instrumentality of electronic cards and system interconnect.System can be arranged usually for identifying the recognition instruction whether electronic cards is inserted, and recognition instruction needs by the sense switch installed on electronic card coupler to send to system.Described sense switch generally comprises two switch terminals, and after electronic cards is inserted, described two switch terminals produce the change connected, as by be closed to open circuit or by open circuit to closure state, thus produce recognition instruction and send to system.Usually, described sense switch comprises moved end and a static terminal, described moved end produces interference deformation and changes the contact condition with described static terminal after described electronic cards is inserted, and the general fillet with described electronic cards of described moved end or afterbody produce and interfere, this kind of mode is in superminiature card class formation, because electronic card coupler is small-sized, moving a little of electronic cards, likely causes the problem that sense switch is malfunctioning.

Summary of the invention

The object of the present invention is to provide the electronic card coupler that a kind of sense switch is reliable and stable.

For this reason, the invention provides a kind of electronic card coupler, comprise insulating body, be shaped in the conducting terminal in insulating body, be located at the sense switch on described insulating body, and the metal shell be covered in above insulating body, described insulating body, conducting terminal, and metal shell is enclosed to form the receiving space for accommodating electronic cards jointly, described sense switch comprises the first switch terminal being located at described insulating body afterbody, and be located at the second switch terminal of described insulating body side, described second switch terminal comprises extend in described receiving space first, the second two bending parts, when described electronic cards is inserted in described receiving space, one side of described electronic cards, and the corner of this side front end respectively correspondence push described first, second bending part.

Compared to prior art, the electronic card coupler of the present invention's design by arranging first, second two bending parts extended in described receiving space on second switch terminal, make the side of electronic cards, push first, second bending part described with corner simultaneously, when described corner pushes not in place, still second switch terminal and described first switch terminal can be disconnected by described first bending part of described side promotion and produce switching signal.

Embodiment

Refer to shown in Fig. 1 to Fig. 6, electronic card coupler of the present invention comprises insulating body 20, the conducting terminal 30 be shaped in described insulating body 20, be located at sense switch 40 on described insulating body 20 and the metal shell 10 of shade above described insulating body 20.Described insulating body 20, conducting terminal 30 and metal shell 10 are enclosed to form the receiving space 60 for accommodating electronic cards 50 jointly.

Refer to shown in Fig. 2, Fig. 3, described insulating body 20 comprises main part 23, be formed at the sidewall 21 of described main part 23 both lateral sides and be formed at the tail wall 22 of described main part 23 afterbody.A described sidewall 21 is positioned at plug-in card side and is provided with second switch terminal groove 211, and described sidewall 21 is provided with near tail wall 22 side and dodges space 212.

Refer to shown in Fig. 2 to Fig. 4, described sense switch 40 comprises the first switch terminal 41 be located on described insulating body 20 tail wall 22 and the second switch terminal 42 be located on a sidewall 21 of described insulating body 20.Described first switch terminal 41 is formed with described conducting terminal 30 integrated punching, comprises the first contact site 411 formed towards the bending of second switch terminal 42 side.The first bending part 422 that described second switch terminal 42 comprises holding parts 421, formed towards the bending of described receiving space 60 direction from described holding parts 421 front end, the second bending part 423 again formed to the bending of described receiving space 60 direction from described first bending part 422 front end and the second contact site 424 extended to form from described second bending part 423 front end.The protuberance 425 of described first bending part 422, second bending part 423 is positioned at described receiving space 60, under the non-insert state of electronic cards, the protuberance 425 of described second bending part 423 compared to the protuberance 425 of described first bending part 422 closer to the mid portion of described receiving space 60.Described first switch terminal 41, with under second switch terminal 42 normality, is in closure state, i.e. normally off.

Please consult shown in Fig. 5, Fig. 6 by emphasis, when electronic cards 50 is inserted in described electronic card coupler, a side 51 of described electronic cards 50 outwards pushes the first bending part 422 of described second switch terminal 42, the corner 52 being positioned at this side 51 front end pushes the second bending part 423 of described second switch terminal 42 laterally, makes the separated generation switching signal of described second switch terminal 42 and described first switch terminal 41.

Adopting separately in prior art pushes in the implementation process of described second switch terminal 42 by described corner 52, may exist and insert and electronic cards has been electrically connected but completely under insert state due to external force vibrations, it is not in place that described corner 52 pushes described second switch terminal 42, makes the situation that sense switch 40 lost efficacy.And the application by arranging first, second two bending parts 422 extended in described receiving space 60 on second switch terminal 42,423, make the side 51 of electronic cards 50, push first, second bending part 422 described with corner simultaneously, 423, when described corner 52 pushes not in place, still can promote described first bending part 422 by described side 51 and make second switch terminal 42 and described first switch terminal 41 disconnect generation switching signal.
