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, places plurality of conductive terminals 30 and earth terminal 40 in this insulating body 20, and the pin connected assembly 50 of this metal shell 10 of a pivot joint and insulating body 20.
Please in conjunction with 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, and the free end of Access Division 121 is formed with a chamfering 1210 near insertion end 101 sides.
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.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.Each buckling groove 212 is irregular polygon, wherein 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.
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.
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.Pin joint seat 52 comprises the pivot connected slot 520 that a cell wall profile becomes closed curve, and this pivot connected slot 520 comprises the first pivot connected slot 520a, second a pivot connected slot 520b who is communicated with again, and a boss 520c who separates this first and second pivot connected slot 520a, 520b.This boss 520c is formed at the downside of pivot connected slot 520 cell walls and roughly locates in the centre position, it can try hard to recommend outside and cross boss 520c under moving with the space between relative pivot connected slot 520 walls for articulating projection 510, thereby between two pivot connected slot 520a, 520b, shift one's position, and follow corresponding feel to help the user to confirm to be pushed into correct position.
As shown in Figure 2, when pivot joint projection 510 was positioned at first pivot connected slot 520, 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.Please in conjunction with Fig. 3,4,5, when pivot joint projection 510 was positioned at the second pivot connected slot 520b, Access Division 121 moves into the second buckling groove 212b and cell wall is closely conflicted, and contacts with the contact site 44 of earth terminal 4.By the interference of the Access Division 121 and the second buckling groove 212b wall, and earth terminal 4 to its stop that metal shell 10 snap lock can not break away from 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.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.
