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, place plurality of conductive terminals 30 and earth terminal 40 in this insulating body 20, and a pin connected assembly 50 that is used to articulate this metal shell 10 and insulating body 20.

Please refer to Fig. 3, Fig. 4, this metal shell 10 comprises the two side 12 that a loam cake 11 reaches from these loam cake 11 both sides approximate vertical protrude out, can supply a SIM card (not icon) to be inserted to pivot end 102, and be contained in the receiving space 13 of this loam cake 11 and sidewall 12 formations by insertion end 101.

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.Equidistantly approximately on the two side 12 protrude out three Access Divisions 121 with loam cake 11 plane almost parallels, the free end of Access Division 121 is formed with a chamfering 1210 near insertion end 101 sides.Near a middle part being arranged between two pairs of Access Divisions 121 of insertion end 101 from the holding division 122 that caves in outside to inside.

Insulating body 20 roughly is H shape, and respectively there is a pair of earth terminal accepting groove 211 position of these H shape two arms 21 symmetries, is used to accommodate earth terminal 40.The transverse part 22 of this H shape is provided with plurality of conductive terminals accepting groove 221 in addition, is used to accommodate corresponding conducting terminal 30.For corresponding with the Access Division 121 on the metal shell sidewall 12, two arms 21 are provided with three pairs of buckling grooves 212, and each buckling groove 212 is irregular polygon.From arm 21 lateral sunken insides darker be the first buckling groove 212a, and relatively depression more shallow be the second buckling groove 212b.The first buckling groove 212a slightly caves inward with the cell wall portion that the second buckling groove 212b is connected, and forms the recess 2120 that cooperates with the chamfering 1210 of Access Division 121.And be provided with a fixing slot 213 between two buckling grooves 212 of holding division 122 corresponding sections, this fixing slot 213 caves on two arms 21 the first fixing slot 213a and the second fixing slot 213b, is intercepted by a projection 213c therebetween.To upper surface 201 certain depth that only caves in, and the second fixing slot 213b is a groove to this first fixing slot 213a, is through to upper surface 201 from lower surface 202 from body 20 lower surfaces 202 that insulate.

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.Holding parts 42 earth terminal accepting groove 211 sidewalls of can conflicting produce to be interfered, thereby earth terminal 40 is immobilizated in earth terminal accepting groove 211.

Pin connected assembly 50 comprises the articulated section 51 of two side 12 ends that extend metal shell 10, and the pin joint seat 52 that extends of two arms, 21 ends of the body 20 that insulate certainly.Articulated section 51 about centre protrude out one and articulate projection 510.Please in conjunction with Fig. 5, pin joint seat 52 comprises a pivot connected slot 520, and this pivot connected slot 520 comprises the first pivot connected slot 520a, the second pivot connected slot 520b of depression, and a boss 520c who is recessed to form by this two pivot connected slot.Pivot joint projection 510 can be crossed boss 520c and shift one's position between two pivot connected slot 520a, 520b under the user promotes, and follows the corresponding buckle sound to help the user to confirm to be pushed into correct position.

As Fig. 2, when pivot joint projection 510 was positioned at the first pivot connected slot 520a, this metal shell 10 can rotate freely with respect to insulating body 20, that is, metal shell 10 articulates to open mode with insulating body 20.Metal shell 10 is fastened on insulating body 20, and the application of force makes pivot joint projection 510 stride across boss 520c and be contained in the second pivot connected slot 520b from the first pivot connected slot 520a.As Fig. 6, Access Division 121 is positioned at the second buckling groove 212b and contacts with the contact site 44 of earth terminal 40 at this moment, and 122 of holding divisions stride across projection 213c and are contained in the second fixing slot 213b.Interference by Access Division and clamping cell wall can be with these metal shell 10 snap lock in insulating body 20, that is, metal shell 10 articulates with lock mode with insulating body 20.

The utility model adopts above-mentioned pin connected assembly that metal shell and insulating body are articulated, and is convenient to operation, and guarantees in needs metal shell to be locked in insulating body, prevents that both break away from.The designs of two depression pivot connected slots and boss can prevent to articulate projection and arbitrarily move in pivot connected slot on the pin joint seat, thereby have convenient transportation, connect stable effect.Simultaneously since contacting of metal shell and earth terminal can effectively shield and the various electromagnetic interference of filtering.

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.
