Description

The composite memory card connector

Technical field

The utility model relates to a kind of memory card connector, particularly a kind of composite memory card connector.

Background technology

With reference to Fig. 1, existing a kind of composite memory card connector 9 comprises a MS terminal group 91 of pegging graft for MS (Memory Stick) memory card (scheming not show), a SD terminal group 92 that supplies SD (Secure Digital) memory card (figure does not show) to peg graft, and reaches an xD terminal group 93 of pegging graft for xD (Extreme Digital) memory card (scheming not show).In addition, with reference to Fig. 2, the little a lot of MS-Duo memory card of a kind of volume ratio MS memory card (figure does not show) can utilize a MS-Duo adapter 94 (MS-Duoadaptor) to be plugged in MS terminal group 91 for interface.

Manufacturing for convenience also reduces the volume that MS-Duo adapter 94 takies, and its diapire 941 is made for the insulation material, and roof 942 and two side 943 are formed by sheet metal, and sheet metal coats to diapire 941 surperficial two side areas 944.But because MS terminal group 91 is positioned at the most inboard of electronic card coupler 9, therefore as shown in Figure 3, when MS-Duo adapter 94 inserted electronic card coupler 9, its two side areas 944 can contact xD terminal group 93 be positioned at the sense switch that outermost power supply terminal 931,932 and detection terminal 933 and earth terminal 934 are formed.So can be coated with an insulating barrier on two side areas 944 surfaces, when avoiding MS-Duo adapter 94 to insert electronic card couplers 9, its two side areas 944 (being coated with sheet metal) makes detection terminal 933 and earth terminal 934 short circuits, and cause that system erroneous judgement inserts be the xD memory card, cause the signal entanglement; And avoid because its two side areas 944 (being coated with sheet metal) contact power supply terminal 931,932 (or only contact one of them also can); and make the power turn-on of xD terminal group 93; but increase electric current and can not arrive default earth terminal via normal loop; make this newly-increased electric current seek earth terminal at random, cause part assembly on the circuit board (figure do not show) because this improper electric current is by causing damage.

Yet, though MS-Duo adapter 94 two side areas 944 are coated with insulating layer coating and can avoid the problems referred to above, but after the process of repeatedly pegging graft and pulling out, because zone 944 usually rubs with terminal 931,932,933,934, make insulating barrier be drawn together to remove and metal level is come out once more, and still can cause the generation of the problems referred to above.

(be the MS-Duo adapter, as shown in Figure 7) the 82 or the 3rd memory card (be the MS memory card, figure does not show) is electrically connected with circuit board second terminal group, 3 usefulness for second memory card.Second terminal group 3 comprises a plurality of conducting terminals 31 and is fixedly arranged on end wall 13, conducting terminal 31 respectively have contact site 312 and that a fixed part 311 that is fixed in end wall 13, extends toward insertion slots 14 by fixed part 311 by fixed part 311 toward the weld parts 313 that extend and be welded in circuit board away from the bending of insertion slot 14 directions.In addition, the 3rd terminal group 4 usefulness are electrically connected with circuit board for the 4th memory card (be the SD memory card, figure does not show).

With reference to Fig. 5 and Fig. 6, when first memory card 81 by inserting port 15 when the plant direction of composite memory card connector 100 enters insertion slot 14 and arrive assigned address, first of the first terminal group 2, two switch elements 5,6 first, two conduction elastic arms 52,62 contact part 523,623 are subjected to pushing of first memory card 81 and touch first, two conducting strips 51,61 second junction 514,614, simultaneously, first, two conducting terminals 53,63 contact site 532,632,633 are also pushed and are contacted first, two conducting strips 51,61 first junction 513,613, make and win, two switch elements 5,6 are in a conducting state (on).What deserves to be mentioned is, the first conduction elastic arm 52 of first switch element 5 is the detection terminals 933 (with reference to Fig. 1) that are used for replacing known connector 9, first conducting terminal 53 then has identical function with the earth terminal 934 of known connector 9, first switch element 5 is used as judges the sense switch whether first memory card 81 pegs graft; Second 62 of the elastic arms of conduction of second switch unit 6 are the weld parts 935 (with reference to Fig. 1) that are used for replacing the power supply terminal of known connector 9, therefore, when second switch unit 6 during at status of electrically connecting, could contact with second junction 614 by the second conduction elastic arm 62 by the power supply of circuit board supply and to conduct to second conducting terminal 63, and conduct to guide card 812 on first memory card 81 by second contact site 632 and/or auxiliary contact site 633.And a plurality of guide cards 811,812,813 on first memory card 81 contact with first, second and third contact site 532,632,712 and auxiliary contact site 633 respectively, and the contact site the 532,632, the 633rd of first and second conducting terminal, are sandwiched between first junction 513,613 and the guide card 811,812.

With reference to Fig. 5 and Fig. 7, when second memory card 82 inserts composite memory card connector 100, because second memory card, 82 width are narrow than first memory card 81, so its left and right sides can not push against first and second conduction

elastic arm

52,62, make first and second conduction

elastic arm

52,62 can not contact, and make first and

second switch element

5,6 be in a not on-state (off) with first and second conducting strip 51,61.Therefore, struck off and become conduction region even the sheet metal zone 821 that is covered with insulating barrier is criticized in second memory card, 82 diapire both sides, and contact, also can not cause system's erroneous judgement or electric power starting to cause the situation of circuit board damage with first and second conducting terminal 53,63.

Conclude above-mentioned, utilize the design of first and

second switch element

5,6, the utility model composite memory card connector 100 can avoid second memory card (being the MS-Duo adapter) 82 to insert the terminal misoperation that is caused, with accurate differentiation second memory card 82 and first memory card (being the xD memory card) 81, the situation that can avoid entanglement of generation systems signal or circuit board to damage is so can reach the purpose of this utility model really.

The above, it only is preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, all simple equivalent of being done according to the utility model claim scope and utility model description change and modify, and all belong to the scope that the utility model patent contains.
