Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, relates in particular to a kind of electronic card coupler that is provided with switching device.

[background technology]

The novel patent announcement of TaiWan, China has disclosed a kind of electronic card coupler that is provided with switching device for M288443 number; It comprises insulating body, is placed in the conducting terminal in the insulating body and is covered in the shielding casing on the insulating body; Said shielding casing is torn away from the electronic cards insertion end and is formed a shell fragment that extends to receiving space; The terminal corresponding position of insulating body and shell fragment is provided with a contact terminal; Said shell fragment and contact terminal have constituted the switching device of electronic card coupler, and said contact terminal is installed on the insulating body end and is a frame shape structure, and form an accepting hole of accommodating said shielding casing shell fragment end.When electronic cards was not inserted electronic card coupler, said shell fragment was positioned at the contact terminal accepting hole and is not connected with contact terminal, is in off-state; When electronic cards was inserted electronic card coupler, the electronic cards pushing tow shell fragment that makes progress made shell fragment upwards electrically connect conducting with the upper side frame of contact terminal accepting hole, thereby realizes switching function.

But above-mentioned electronic card coupler requires smoother to the contact between contact terminal and the shell fragment, and in process of producing product, the contact of said contact terminal might form and rough contact-making surface, thereby influences the contact performance of switching device.

Therefore, necessary a kind of electronic card coupler that can overcome aforementioned disadvantages is provided.

[utility model content]

The purpose of the utility model is to provide a kind of switching device contact good electron card connector.

For reaching above-mentioned purpose; The utility model adopts following technical scheme: a kind of electronic card coupler; Comprise insulating body, be contained in the interior conducting terminal of insulating body, be covered in shielding casing and switching device on the insulating body; Insulating body comprises base portion and the afterbody that forms away from electronic cards insertion end one side at base portion; Said switching device comprises shell fragment terminal and contact terminal, and the shell fragment terminal is to tear formation from the corresponding insulating body afterbody of shielding casing one end, contact terminal be arranged at insulating body afterbody and shell fragment terminal corresponding position and with the shell fragment termination contact; Said contact terminal comprises that connecting portion reaches the contact of the circular arc type bending structure that extends to form from connecting portion.

Compared with prior art, the utlity model has following beneficial effect: through contact terminal the contact of circular arc type bending structure is set, has solved the unstable defective of prior art switching device electrical contact performance.

[embodiment]

Please referring to figs. 1 through shown in Figure 3, the utility model electronic card coupler 100 comprises insulating body 10, is installed on the conducting terminal 30 in the insulating body 10 and is covered in the shielding casing 20 on the insulating body 10.Said insulating body 10 is set as the receiving space 5 that is used to accommodate electronic cards with shielding casing 20 one common peripheral.

Said insulating body 10 comprises base portion 11, be positioned at base portion 11 both sides and away from electronic cards insertion end one side is one-body molded afterbody 13 arranged with the integrated sidewall of base portion 11 12, base portion 11.Said conducting terminal 30 is contained in said insulating body 10 base portions 11.Said sidewall 12 bottom surfaces are provided with some draw-in grooves 121.The opening 131 that connects before and after said insulating body 10 afterbodys 13 offer.

Said shielding casing 20 is covered on the insulating body 10; It comprises the fastener 22 in the insulating body 10 bottom surface draw-in grooves 121 that is fastened in that

main part

21 and 21 liang of lateral bucklings of autonomous body extend to form, and the draw-in groove 121 that promptly said sidewall 12 bottom surfaces form holds with fastener 22 mutually.Said main part 21 is torn on the direction of corresponding insulating body 10 afterbodys 13 openings 131 and is formed with shell fragment terminal 23; Said shell fragment terminal 23 extends to form in electronic cards receiving space 5; The shell fragment terminal 23 terminal contact feets 231 that form, said contact feet 231 is positioned at insulating body 10 openings 131 positions.

Said electronic card coupler 100 comprises a switching device 6; Said switching device 6 comprises the shell fragment terminal 23 and the contact terminal 40 of shielding casing 20; Said contact terminal 40 comprises connecting portion 41 and the weld part 42, the contact 43 that extend to form from connecting portion 41; Said connecting portion 41 is platy structure substantially and is shaped in insulating body 10 base portions 11; Said contact 43 is circular arc type and is bent to form down " U " type structure and is positioned at insulating body 10 openings 131 positions, and " U " type structure of falling of said contact 43 forms the smooth contact site 431 that is in contact with one another with shielding casing 20 shell fragment terminals 23 contact feets 231 in top in insulating body 10 openings 131.The contact 43 of said circular arc type bending offers breach 44 at the top, said breach 44 laterally runs through to be offered.Said contact 43 is the circular arc type bending structure, through form the whole contact performance that smooth contact site 431 can improve switching device 6 in the top.Contact terminal 40 integral body take shape in the insulating body 10; The contact 43 of circular arc type bending structure is unfavorable in forming process, locating; Cause contact 43 dislocation easily; And the breach 44 that is provided with on the contact 43 can let die insert into the inner in forming process whole contact terminal 40 is positioned, thereby has solved orientation problem.

The switching device 6 of said electronic card coupler 100 is not when electronic cards is inserted; Shell fragment terminal 23 contacts conducting with contact terminal 40, after electronic cards is inserted, and the electronic cards pushing tow shell fragment terminal 23 that makes progress; Shell fragment terminal 23 and contact terminal 40 are broken off, thereby realize switching function.

The utility model electronic card coupler 100 is provided with the contact 43 of circular arc type bending structure through contact terminal 40, has solved the unstable defective of prior art switching device electrical contact performance.
