Embodiment
Below, cooperate graphic some preferred embodiments of enumerating now, in order to detailed structure of the present utility model and effect to be described.The tenth figure is this sectional perspective constitutional diagram of creating the 4th preferred embodiment.
See also Fig. 1 to shown in Figure 3, the card connector 10 for the utility model first preferred embodiment is provided mainly comprises:
One housing 20 cooperates a cover plate 12 to be formed by a pedestal 21, housing 20 have one be positioned at front end open 22, and one oneself open the 22 plug-in card spaces 23 that extend to housing 20 inside.Housing 20 can be inserted in order to the memory card 48 that cooperates MS (Memory Stick) specification in opening 22 and plug-in card space 23.
Plug-in card space 23 2 sides of housing 20 form two sidewalls 24 respectively, and wherein a sidewall 24 nearly openings 22 places have a room 25, and room 25 is communicated in plug-in card space 23.Have in the room 25 of pedestal 21 one be cylindric upwardly extending first location division 42 and be skewed within wall 26, inwall 26 has a location notch 27, is provided with a fixed part 28 that is cylindric horizontal expansion in the location notch 27.Sidewall 24 has one second location division 29 and a top 45 respectively in room 25 2 sides.
One stop part, 30, one ends have a joint portion 31 and single order portion 36 in order to be incorporated into first location division 42, and the other end has a bearing surface 32, and in the present embodiment, joint portion 31 is a circular groove.Has an inclined-plane 33 between bearing surface 32 and the joint portion 31.Bearing surface 32 belows of stop part 30 are provided with a catch 34 and a cylindrical fixed part 35.Stop part 30 is located in the room 25 of pedestal 21, makes joint portion 31 be sheathed on first location division 42 of room 25, and stop part 30 can be located in the room 25 to deflection.
One elastic component 40 is the compression spring, and elastic component 40 is located in the room 25 of pedestal 21, and an end is sheathed on the fixed part 28 of pedestal 21, and the other end is sheathed on the fixed part 35 of stop part 30.The bearing surface 32 that the elastic force of elastic component 40 can promote stop part 30 moves towards protruding from plug-in card space 23 directions, if after stop part 30 was promoted by the elastic force of elastic component 40, catch 34 was butted on the top 45 of pedestal 21, stop part 30 just can not break away from room 25.
By above-mentioned structure explanation of the present utility model, when MS memory card 48 is desired opening 22 via housing 20 and is inserted plug-in card spaces 23, if putting of MS memory card 48 is in the right direction, as Fig. 1 and shown in Figure 3, the circular arc limit 49 of MS memory card 48 is inserted earlier and is opened in 22, circular arc limit 49 can bearing surface 32 outer rims direct and stop part 30 be in contact with one another, and along with MS memory card 48 when plug-in card space 23 pushes housing 20, circular arc limit 49 continues to promote stop part 30 deflections and compression elastic piece 40, make bearing surface 32 gradually in the retraction room 25, MS memory card 48 can insert housing 20 smoothly.And when MS memory card 48 is extracted housing 20, the involution elastic force of elastic component 40 then can promote stop part 30 deflections again, make bearing surface 32 protrude from plug-in card space 23 from sidewall 24, be butted on second location division 29 up to the rank of stop part 30 one 36, catch 34 is butted on till the top 45.
As Fig. 4 and shown in Figure 5, if MS memory card 48 is put the direction interpolation that becomes to turn one's coat and is inserted housing 20, and not to open 22 with what housings 20 were inserted on circular arc limit 49 earlier, but inserting housing 20 with a rectangular shape corner wherein, MS memory card 48 rectangular-shaped corner end faces can directly be resisted against the bearing surface 32 of stop part 30.Because the corner end face and the bearing surface 32 mutual contacts of rectangular shape, MS memory card 48 can't promote stop part 30 towards room 25 intrinsic deflections, and MS memory card 48 just can't insert in housing 20 again.Figure 6 and Figure 7 for another example, as long as MS memory card 48 is not to insert housing 20 with correct direction, at right angles the corner end face of shape all can contact at bearing surface 32, make MS memory card 48 can't insert connector 10.
By this, but the utility model can utilize the technical characterictic of the pedestal setting deflection stop part of housing, when the MS memory card inserts pedestal with correct direction, the MS memory card can promote stop part deflection, if and the MS memory card is when inserting pedestal with the opposite way round, memory card will be subjected to the contact of stop part and can't insert pedestal, reaches the purpose that prevents that the MS memory card from mispluging.
In addition, as shown in Figure 8, be the card connector 50 that the utility model second preferred embodiment is provided, its major technique feature and first preferred embodiment are roughly the same, and characteristics are do not have fixed part in the room 52 of pedestal 51, elastic component 53 1 ends are sheathed on the fixed part 55 of stop part 54, the other end then is located in the location notch 56, and by this, elastic component 53 also can provide the elastic force that promotes stop part 54 deflections, make bearing surface 57 protrude from sidewall 58, catch 59 is butted on top 60.
Also can utilize multiple mode to mutually combine between stop part provided by the utility model and the pedestal.As shown in Figure 9, the card connector 61 that the 3rd preferred embodiment is provided by the utility model, its major technique feature is also roughly the same with first preferred embodiment, the joint portion 66 of stop part 63 is sheathed on first location division 65 of pedestal 62, make the stop part 63 can be in pedestal 62 deflections, have a top 67 and characteristics are 62 of pedestals in relative stop part 63 belows, pedestal 62 does not have second location division, and stop part 63 does not need rank portion yet.By this, top 67 can not break away from stop part 63 with room 68 in order to the catch 64 of butt stop part 63 mutually.
For another shown in Figure 10, the card connector 70 that is provided for the utility model the 4th preferred embodiment, its major technique feature is also roughly the same with first preferred embodiment, characteristics are that then pedestal 71 still is provided with second location division 73 and and is the first circular- arc location division 75, and 74 surfaces, joint portion of stop part 72 are for being the arc surface of corresponding first location division 75, when the elastic force of elastic component 77 acts on stop part 72, stop part 72 can utilize joint portion 74 to be embedded in first location division 75 and deflection, and catch 78 is butted on top 76.By above-mentioned multi-form structure, the utility model still can be reached and make stop part deflection, and prevents the function that the MS memory card misplugs.
