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 2, 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.
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 supply a SIM card (not icon) to be inserted to pivot end 102 by insertion end 101, and be contained in the receiving space 13 of this loam cake 11 and sidewall 12 formations.
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 bent sheet 113 near two side 12 place's approximate vertical, and wherein a bent sheet 113 inboard omiting have a L shaped butting section 114 to receiving space 13 diagonally extendings.When SIM card is inserted receiving space 13, slip over two shell fragments 112 through pushing and prop up, thereby but assisting users is inserted to the tram with SIM card for butting section 114.The pushing of two shell fragments 112 can make SIM card keep the location, can not influence and conducting terminal 30 stability in contact because of arbitrarily moving.
Two side 12 is respectively equipped with an articulated section 121 at pivot end 102, and these articulated section 121 terminal central authorities protrude out a pivot 122 (please in conjunction with Fig. 4 b, 5b).Protrude out three Access Divisions 123 with loam cake 11 plane almost parallels from insertion end 101 to pivot end 102 is equidistant approximately, the free end of this Access Division 123 is formed with a chamfering 1230 near insertion end 101 sides.Near a middle part being arranged between two pairs of Access Divisions 123 of insertion end 101 from the holding division 124 that caves in 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; And 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 pivoted holes 213 that are communicated with, and wherein that close end is free pivoted hole 213a, and another then is locking pivoted hole 213b (please in conjunction with Fig. 4 b, 5b).Protruded out two symmetrical boss 213c on the sidewall of two pivoted holes, 213 connections place, the space between the boss 213c can be crossed boss 213c and shifts one's position 213 of two pivoted holes for the pivot 122 of the articulated section 121 of metal shell 10 under user's promotion.For corresponding with the Access Division 123 on the metal shell sidewall 12, two arms 21 are provided with three pairs of buckling grooves 214.Each buckling groove 214 is irregular polygon, wherein from arm 21 lateral sunken insides darker be the first buckling groove 214a, and relatively depression more shallow be the second buckling groove 214b.The first buckling groove 214a slightly caves inward with the cell wall portion that the second buckling groove 214b is connected, and forms the recess 2140 that cooperates with Access Division 123 chamferings.And be provided with a fixing slot 215 between two buckling grooves 214 of holding division 124 corresponding sections, this fixing slot 215 caves on two arms 21 the first fixing slot 215a and the second fixing slot 215b, is intercepted by a projection 215c between two grooves.To upper surface 201 certain depth that only caves in, and the second fixing slot 215b is a groove to this first fixing slot 215a, is through to upper surface 201 from lower surface 202 from body 20 lower surfaces 202 that insulate.
As shown in Figure 3, earth terminal 40 is a bending sheet metal, have holding parts 42 that a weld part 41 that can be soldered to circuit board (not icon), extends from these weld part 41 1 end approximate vertical, this weld part 41 other end approximate vertical bending and extend the connecting portion 43 of holding parts 42 homonymies certainly, and the contact site 44 that extends from the bending of connecting portion 43 approximate vertical.The free end of holding parts 42 is formed with a pair of groove 421, and both sides have protruded out interference part 422, can conflict earth terminal accepting groove 211 sidewalls and produces interference, thereby earth terminal 40 is immobilizated on the insulating body 20.
As shown in Figure 6, the boss 213c that the application of force makes the pivot 122 of articulated section 121 cross 213 of two pivoted holes slips into locking pivoted hole 213b, and holding division 124 is crossed projection 215c and entered among the second fixing slot 215b.This moment, Access Division 123 moved to the second buckling groove 214b (can with reference to other correlation diagrams) by cooperating smoothly by the first buckling groove 214a of its chamfering 1230 and buckling groove 214 wall upper recess 2140, wherein the contact site 44 of corresponding earth terminal 40 contacting metal housings two walls 12 close 123 places, Access Division respectively.By the tight conflict of the Access Division 123 and the second buckling groove 214b, metal shell 10 gets final product snap lock in insulating body 20, and both can not throw off.
Be actually and be convenient to transport common need and metal shell is threaded to insulating body amounts to the position.Because when locking, contact site was to contact in the horizontal direction with metal shell, the active force of the vertical direction of the metal shell coplanarity that can not exert an influence, thereby insulating body and metal shell can lock and can not influence the performance of connector at any time.Therefore the utility model also can be removed the design (promptly remove holding division on the metal shell and reach fixing slot on the insulating body corresponding with it) of metal shell and insulating body engaging under open state, thereby makes whole sim card connector structure more simple.
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.
