Description

Sim card connector

Technical field

The utility model relates to a kind of electronic card coupler, refers in particular to a kind of subscriber identification card (Subscriber Identity Module, SIM card) connector that is applied in information or communication apparatus inside.

Background technology

Along with the development of information technology, personal communication apparatus such as mobile phone obtain application more and more widely.Wherein as the SIM card of user identity identification, realize and being electrically connected of circuit board by a sim card connector.Correlation technique can be with reference to United States Patent (USP) the 5th, 996, and No. 891, it discloses a kind of sim card connector commonly used.Such sim card connector roughly comprises metal shell, an insulating body, the plurality of conductive terminals that is contained in insulating body and a corresponding pin connected assembly for the SIM card plant.Pin connected assembly comprises the articulated section that extends metal shell one end, with the pin joint seat that extends insulating body one end.The articulated section can be contained in the pin joint seat, thereby realizes the pivot joint of metal shell and insulating body.The SIM card of inserting can not deviate from metal shell against the pin joint seat surface by end.

Because metal shell can rotate with respect to insulating body, the continuous friction of SIM card and pin joint seat will cause rotation not smooth.Simultaneously, because of SIM card is the relative metal shell that is contained in, the continuous variation of its position very easily causes the loose contact with the contact position generation deviation of conducting terminal.For cooperate SIM card against, the profile of pin joint seat also is restricted, and can not satisfy the demand of product diversification.Thereby existing sim card connector is needed badly and is improved.

Summary of the invention

The purpose of this utility model is to provide a kind of sim card connector, and it can guarantee stable being immobilizated in the metal shell of SIM card, provides necessary assurance for realizing high communication quality.

For achieving the above object, the utility model sim card connector adopts following technical scheme, and it comprises: a metal shell, one and the insulating body that articulates of this metal shell, and some conducting terminals that place in this insulating body.

This metal shell has a loam cake, and one end approximate vertical is extended with at least one kink, and wherein at least one kink is slightly to SIM card direction of insertion diagonally extending one L shaped butting section.When SIM card is inserted, can be kink and butting section against, on the one hand assisting users is inserted to the tram with it, prevents that on the other hand it from deviating from metal shell.This loam cake also is provided with at least one shell fragment along the SIM card direction of insertion, can compress SIM card and make it keep stable.

The beneficial effect of the utility model sim card connector is: what SIM card can be stable is immobilizated in the metal shell, guarantees and good being electrically connected of conducting terminal.Because of SIM card need not against insulating body, can guarantee metal shell and the glitch-free rotation of insulating body on the one hand, can too much not limit the insulating body profile on the other hand.

Embodiment

For ease of better understanding the utility model, existing preferred to of the present utility model one in conjunction with the accompanying drawings

Embodiment is described in detail as follows:

As shown in Figure 1, the utility model sim card connector 1 comprises a metal shell 10, an insulating body 20 that can articulate with this metal shell 10, and places plurality of conductive terminals 30 and earth terminal 40 in this insulating body 20.

Please in the lump with reference to figure 2, this metal shell 10 comprises a loam cake 11 and from the two side 12 that these loam cake 11 both sides approximate vertical protrude out, can be inserted to pivot end 102 by insertion end 101 for a SIM card 2 (asking for an interview Fig. 3).

Be penetrated with some circles or similar oval-shaped through hole 111 on this loam cake 11.Loam cake 11 about center are extended with two shell fragments 112 to pivot end 102, and its pivot end 102 is extended with two kinks 113 near two side 12 place's approximate vertical, and wherein a kink 113 inboard omiting have a L shaped butting section 114 to insertion end 101 diagonally extendings.

Two side 12 is respectively equipped with an articulated section 121 at pivot end 102, and each articulated section 121 terminal central authorities protrudes out a pivot 122.Also roughly equidistantly be extended with three Access Divisions 123 with loam cake 11 plane almost parallels in addition on the sidewall 12, near a middle part being arranged between two pairs of Access Divisions 123 of insertion end 101 from the holding division 124 of depression outside to inside.

Insulating body 20 roughly is H shape, and wherein respectively there is a pair of earth terminal accepting groove 211 position of H shape two arms 21 symmetries, is used to accommodate earth terminal 40; The transverse part 22 of H shape is provided with plurality of conductive terminals accepting groove 221, is used to accommodate corresponding conducting terminal 30.Two arms, 21 1 ends are pin joint seat 212, which is provided with two pivot connected slots 213 that are communicated with, and wherein that close end is free pivot connected slot 213a, and another then is locking pivot connected slot 213b.Protruded out two symmetrical boss 213c on the sidewall of both connections place, the space between the boss 213c can be crossed boss 213c and shifts one's position 213 of two pivot connected slots for the pivot 122 of articulated section 121 on the metal shell 10 under user's promotion.Corresponding with the Access Division 123 on the metal shell sidewall 12, two arms 21 are provided with three pairs of buckling grooves 214, and be provided with a fixing slot 215 between two buckling grooves 214 of holding division 124 corresponding sections, to protrude out that a projection 215c separates it be the first fixing slot 215a and the second fixing slot 215b to this fixing slot 215 at the middle part approximately.

Earth terminal 40 is a bending sheet metal, have one can be soldered to weld part 41 on the circuit board (not icon), from these weld part 41 approximate vertical along the holding parts of stretching 42, these holding parts 42 almost parallels extend the connecting portion 43 of weld part 41 tops certainly, and from bending of connecting portion 43 approximate vertical and the contact site 44 that slightly extends to weld part 41 place plane inclinations.Holding parts 42 earth terminal accepting groove 211 sidewalls of can conflicting produce to be interfered, thereby earth terminal 40 is immobilizated on the insulating body 20.

When pivot 122 was contained in free pivot connected slot 213a, metal shell 10 can rotate freely with respect to insulating body 20.As Fig. 3, Fig. 4,, SIM card 12 is inserted along the two side by insertion end 101 with insulating body 20 at an angle the time (not amounting to) at metal shell 10, slip over two shell fragments, 112 contact butting sections 114 through pushing.Slightly application of force pushing butting section 114 makes SIM card contact kink 113, is about to SIM card and is inserted to the tram.By the pushing of two shell fragments 112 and kink 113, butting section 114 against making SIM card 2 keep the location, can not be subjected to the influence of metal shell 10 rotations and be shifted.Because of not contacting, therefore can not influence the rotation of metal shell 10 with respect to insulating body 20 with insulating body 20.In addition, pin joint seat 212 profiles of insulating body 20 ends also can cooperate the corresponding adjustment of shape of product.

Technology contents of the present utility model and technical characterstic disclose as above, yet those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and done all replacement and modifications that does not deviate from the utility model spirit.Therefore, protection range of the present utility model should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present invention and modifications, and is contained by the present patent application claim.
