[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. 6068514, United States Patent (USP), and TaiWan, China patent M317095 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.

Therefore, be necessary the conducting terminal of 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, but conducting terminal inside self provides precompression.

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 insulation in this pedestal plurality of conductive terminals 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, reach the fixed arm that own elasticity arm one side extends to form, the end of fixed arm is provided with and is used for the welding foot that contacts with printed circuit board (PCB), described fixed arm is provided with the pre-pressure arm that extends to elastic arm, and this pre-pressure arm is crimped on the elastic arm.

Compared to prior art, electronic card coupler of the present utility model is by being provided with a pre-splenium in conducting terminal self, in conducting terminal and insulating body assembling process, this pre-splenium can reduce conducting terminal and act on the power that makes progress on the insulating body, and conducting terminal self has elastic restoring force preferably, can contact with card is stable.

[embodiment]

See also shown in Figure 1, the utility model electronic card coupler is used to accommodate SIM card (not shown), it comprises insulating base 3, be installed on the plurality of conductive terminals 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, and will fix on insulating base 3.

See also shown in Figure 2, insulating base 3 structure that roughly is square, comprise bottom 30 and the pair of sidewalls 31 that 30 both sides vertically bend 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, terminal hole 301 both sides are formed with plurality of fixed hole (not label), and these fixing holes penetrate bottom 30 upper surface at present embodiment, also can be blind bore up and down in other embodiments.Each sidewall 31 top is the recessed step surface 311 that is formed with downwards.

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 on the sidewall 31 of described insulating base 3, and main part 10 is fixed on the step surface 311 on described insulating body 3 sidewalls 31 just, at this moment, the upper surface of main part 10 and sidewall 31 the highest vertically highly suitable can be reduced the whole height of electronic card coupler like this.

Please continue to consult shown in Figure 3, each conducting terminal 2 structure that roughly takes the shape of the letter U is formed by the sheet metal punching press, and it comprises fixed arm 20, elastic arm 21 and the linking arm 22 that elastic arm 21 is connected with fixed arm 20, elastic arm 21 is positioned at fixed arm 20 tops, linking arm 22 curved extensions.Elastic arm 21 comprises waist 210 and continues the elastic portion 211 of extension from waist 210, waist 210 is offered a roughly T-shaped perforate 212, the narrower side of this perforate 212 is near contact site 211, and a side of broad is away from contact site 211, and this narrower side and broad one side can be exchanged certainly.Fixed arm 20 both sides are respectively equipped with the branch 201 of bending straight up, fore-end extends to form weld part 202, centre is torn the pre-pressure arm 203 that formation is vertically extended towards elastic arm 21, this pre-pressure arm 203 is T word configuration, it comprises broad head 2031 and narrower extension 2030, head 2031 is gone into a narrower side by a sideslip of perforate 212 broads of described elastic arm 21, because the width of head 2030 is greater than the width of described perforate 212 narrower sides, and the whole height of pre-pressure arm 203 is less than elastic arm 21 and the height of fixed arm 20 under free state, the head 2030 of therefore pre-pressure arm 203 is crimped on the waist 210, make elastic arm 21 have the upwards trend of strain, be conducting terminal 2 in not being installed on insulating body 3 time, a downward precompression that self provides is provided in advance.In most preferred embodiment, the head 2030 of pre-splenium 203 is exposed to outside the insulating body 3, so that reduce the whole height of insulating body 2.

In sum, by conducting terminal 2 a pre-splenium 203 is set self, bury before moulding crosses at conducting terminal 2 and insulating body 3 edges, conducting terminal 2 is subjected to downward pressure in advance, and then in conducting terminal 2 and insulating body 3 assembled formation processes, this pre-splenium can reduce conducting terminal 2 and act on the power that makes progress on the insulating body 3, under the optimum state, the power that insulating body 3 can not made progress by conducting terminal 2, and then can prevent insulating body 3 distortion, make insulating body 3 have flatness preferably, and conducting terminal has elastic restoring force preferably, can contact with card is stable.

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.
