[background technology]
All need on the mobile phone at present to be equipped with a sim card connector to realize the electric connection of SIM card and mobile phone internal circuit board.Existing multiple electronic card coupler of accommodating SIM card, as No. 6231349, U.S. Pat, and US6354394 number, it all discloses a kind of electronic card coupler that is used to accommodate SIM card, such electronic card coupler mainly comprises insulating base, is contained in the plurality of conductive terminals in the insulating base and is covered in metal cap body on the insulating base.Each conducting terminal front end is provided with a pre-splenium, this pre-splenium is held in the insulating body, make conducting terminal be subjected to downward pressure in advance, increase the elastic restoring force of conducting terminal, and the mode that these conducting terminal utilization edges bury moulding is fixed in the insulating base, promptly in the insulating base forming process, simultaneously the edge of the conducting terminal on the strip is embedded in the insulating base, making conducting terminal and insulating base is one in itself.
Yet in terminal and insulating body forming process, because the terminal front end is subjected to the downward pressure of insulating body, therefore the terminal front end can produce power upwards to insulating body, like this in the insulating body forming process and uncolled when good, insulating body is easy to distortion, the power that the terminal front end makes progress can make the insulating body upper surface deform, and then has damaged the surperficial degree of insulating body.
In order to make insulating body reach flatness preferably, usually the terminal front end can be in free state, promptly do not fix with insulating body, but be the cantilever type setting, yet the terminal of this state is when the card plug, may scratch the surface of card, perhaps block front end and the conducting terminal front end is inconsistent, conducting terminal is deformed.
Therefore, be necessary existing electronic card coupler is improved to overcome the defective of prior art.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of electronic card coupler that is used to accommodate SIM card, and it has flatness good insulation body, and can protect electronic cards and conducting terminal.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electronic card coupler, it comprises insulating base, be contained in the plurality of conductive terminals in this pedestal of insulation and be covered in metal shell on the insulating base, wherein, insulating base is provided with the terminal hole that is used to accommodate described conducting terminal, each conducting terminal comprises the elastic arm that is provided with contact site, be used for the welding foot that contacts with printed circuit board (PCB), described conducting terminal is provided with the pre-splenium that extends to the contact site direction, and the contact site top is provided with the holding part with pre-splenium butt.
Compared to prior art; electronic card coupler of the present utility model is by being provided with a pre-splenium; this pre-splenium presses down the contact site front end in advance; insulating base is in forming process; can not be subjected to the power that conducting terminal contact site front end makes progress; and then insulating base can not be out of shape, but protection card and conducting terminal simultaneously.

Fig. 4 is a wherein conducting terminal stereogram of the utility model electronic card coupler.
[embodiment]
See also Figure 1 and Figure 2, the utility model electronic card coupler is used to accommodate SIM card, it comprises insulating base 3, be installed on the conducting terminal 2 in the insulating base 3 and be covered in metal shell 1 on the insulating base 3, insulating base 3 matches with metal shell 1 and is formed for accommodating the accepting groove 4 of described card, wherein, insulating base 3 usefulness plastic materials are made, metal shell 1 is used to shield static, provide a downforce to the card that is contained in the described accepting groove 4 simultaneously, will fix on insulating base 3.
Please again in conjunction with shown in Figure 3, insulating base 3 structure that roughly is square comprises bottom 30 and the vertical pair of sidewalls 31 of bending in 30 both sides from the bottom, wherein, bottom 30 is tabular, with the plug of support card, and which is provided with two row's terminal holes 301 of arranging along card plug direction.The inboard of each sidewall 31 is provided with groove 311, is formed at the projection 310 and a pair of through hole 312 that connects bottom 30 from groove 311 1 sides on groove 311 surfaces.
Described metal shell 1 comprises the arm 11 of main part 10 and 10 liang of lateral bucklings of autonomous agent, each arm 11 correspondence is held in the groove 31 of described insulating base 3, which is provided with described insulating base 3 on projection 310 perforate 110 that interlocks and hold, be formed with registration arm 111 from each arm 11 bottom to accepting groove 4 inner bendings.The through hole 312 that registration arm 111 is passed on the described insulating base 3 further fixes metal shell 1 and insulating base 3.Because the arm 11 of metal shell 1 is located in the insulating base 3 inboard set grooves 311, and then can dwindle the width of whole electronic card coupler.
Please continue to consult shown in Figure 4, the roughly rectangular frame structure of each conducting terminal 2, form by the sheet metal punching press, it comprises base portion 20, be positioned at the installation portion 23 of base portion 20 opposite sides, the connecting portion 21 that connects base portion 20 and installation portion 23, and the elastic arm 22 that is positioned at connecting portion 21 opposite sides, wherein, extend to form welding foot 231 under installation portion 23 1 side direction, this welding foot 231 is for fixing on the printed circuit board (PCB), close on welding foot 231 1 lateral elasticity arms 22 directions and extend to form pre-splenium 232, elastic arm 22 front ends upwards smoothly are bent to form and are used for and the contacted contact site 220 of card, contact site 220 free ends extend to form holding part 221 forward, this holding part 221 presses on described pre-splenium 232 belows, and partly edge is embedded in the insulating base 3.
In sum, conducting terminal 2 closes on welding foot 231 1 sides and is provided with the pre-splenium 232 that extends to elastic arm 22, a downforce is provided in advance the holding part 221 of elastic arm 22 ends by this pre-splenium 232, when conducting terminal 2 and insulating base 3 moulding, insulating base 3 need not the front end of conducting terminal 2 is carried out precompressed, conducting terminal 2 front ends equally can not produce power upwards to insulating base 3 yet, can prevent that like this insulating base 3 from upwards deforming in forming process, and then can obtain surperficial degree good insulation pedestal 3.In addition, because pre-splenium 232 in advance to the precompressed of contact site 22 front ends, is stuck in the plug process and can collide with contact site 220 tops, and then avoids terminal that card is scratched, perhaps block front end and conducting terminal 2 contact sites 220 tops are inconsistent, the situation that conducting terminal is deformed.
Conducting terminal is used for contacting with SIM card in the present embodiment, but its structural design is not limited only in such electronic card coupler.
