Description

Electronic card coupler

Affiliated technical field

The utility model relates to a kind of electronic card coupler, especially relates to a kind of retreat-card device of electronic card coupler.

Background technology

Because the electronic card form Storage Media has compact, high storage capacity, shatter-proof, excellent specific property such as repetitive memory repeatedly, therefore be used in widely on information household appliances, personal computer or the portable digital product in recent years.When yet electronic cards is connected with computer, must be by the media of connector, so that the reading and storing of main frame as transmission.

Electronic cards is installed on connector efficiently or takes out for convenient, thereby designed the retreat-card device of a lot of layout architectures, realize this purpose from connector.Existing electronic card coupler 100 as shown in Figure 6, this retreat-card device is made of slide block 102, guide rod 104, spring 108, slide block 102 is located in the set slideway of insulating body 107, be provided with 104 movable ends, 105 slips of confession guide rod and have ladder chute 103 in slide block 102, the other end 106 of guide rod 104 is a stiff end, rotatable being positioned on the insulating base frame side suppressed on guide rod 104 by the set shell fragment 101 of metal shell again, prevents to beat and breaks away from sliding trace.Be resisted against between insulating base frame and the slide block 102 by spring 108 and form retreat-card device, when electronic cards is inserted this connector and promoted slide block, in chute, slide, realize moving back the card effect by guide rod.Yet the retreat-card device of this structure is complex structure not only, and slide block thickness is thicker relatively, and whole connector height is increased, and also comparatively inconvenience of parts assembling, moves back also instability comparatively of card performance.

Therefore, at the existing defective of above-mentioned electronic card coupler, be necessary existing card connector retreat-card device is carried out design improved in fact, so that a kind of electronic card coupler with the retreat-card device of optimizing structure to be provided.

Summary of the invention

Main purpose of the present utility model is to provide a kind of electronic card coupler, the set relative insulating base frame sidewall of guide rod of this connector retreat-card device is skewed, one end is fixed in the insulating base frame side end face, one end is movable in the set plane of slide block, realize moving back the card effect by producing deformation with the prominent guidance part conflict of establishing in plane, so structure is to reduce whole connector height.

For achieving the above object, can be realized by the following technical programs:

The utility model electronic card coupler, it comprises metal shell, insulating base frame, be contained in the conducting terminal of insulating base frame, be installed on the retreat-card device of insulating base frame side.Described retreat-card device is made up of slide block, spring, guide rod, slide block is located in the set slideway of insulating body, be provided with the plane that supplies guide rod one end activity in slide block, and on the plane, dash forward and establish the active path of a guidance part with the guiding guide rod, the other end of guide rod is fixed on the insulating base frame sidewall conduit and is inclined with sidewall, be resisted against between insulating base frame and the slide block by spring and form retreat-card device, when electronic cards is inserted this connector promotion slide block, move back card against producing recoverable elastic deformation with realization by guide rod and guidance part.

Compared with prior art, the retreat-card device of the utility model electronic card coupler slides for guide rod by the plane is set, increase connector thickness to reduce prior art step trough structure, guide rod and sidewall are inclined simultaneously moves back card principle against producing recoverable elastic deformation with realization with guidance part.

For the personnel that the purpose of this utility model and architectural feature can further be allowed be familiar with this technology understand, cooperate appended graphicly, with a concrete case study on implementation the utility model is described further.

Utility model:

The 1-insulating base frame, 11-slideway, 12-conduit, 2-metal cap body, 3-slide block, the 31-plane, 32-guidance part, 321-skew wall face, 33-teat, 34-skew wall, the 35-pushing portion, 4-spring, 5-guide rod, 51-stiff end, the 52-movable end, 53-primary importance, the 54-second place, 55-the 3rd position, 56-the 4th position, 57-the 5th position, 58-the 6th position, 59-the 7th position, the 6-conducting terminal, 7-switch terminal, 8-electronic cards, 9-electronic card coupler.

Embodiment

As shown in Figure 1, the utility model electronic card coupler, the retreat-card device that it comprises metal shell 2, insulating base frame 1, is contained in the conducting terminal 6 of insulating base frame 1, is installed on the switch terminal 7 of insulating base frame 1 side and is assemblied in the insulating base frame opposite side.Retreat-card device is by slide block 3, spring 4, guide rod 5 is formed, slide block 3 is located in the set slideway 11 of insulating body 1, simultaneously with reference to shown in Figure 2, be provided with the plane 31 that supplies 52 activities of guide rod 5 movable ends in slide block 3, and the prominent guidance part 32 of establishing produces fixedly active path with guiding guide rod movable end 52 on plane 31, the stiff end 51 of guide rod 5 is fixed positioned in the set conduit 12 of insulating base frame 1 sidewall simultaneously, described conduit 12 is the inclined groove, inclined when forcing guide rod 5 stiff ends 51 fixedly with respect to insulating base frame sidewall 10, be resisted against between insulating base frame 1 and the slide block 3 by spring 4 and form retreat-card device.

As Fig. 3, shown in 4, when electronic cards 8 insertion electronic card couplers 9 promote, simultaneously with reference to shown in Figure 5, partial enlarged drawing for A position cutaway view among Fig. 4, guide rod 5 one end stiff ends 51 are fixed in the set conduit of insulating base frame end face 12, the other end is a movable end 52, this moment is by the insertion of electronic cards 8, promote the set pushing portion 35 of slide block 3, shown in the figure direction of arrow, for guide rod 5 movable ends 52 move the signal track position, movable end 52 move freely and with guidance part 32 skew wall faces 321 against, make guide rod 5 relative horizontal planes that the bent change of elasticity can take place, movable end 52 moves to the second place 54 by primary importance 53 along the arrow direction, because elastic-restoring force effect, movable end 52 is beated to the 3rd position 55, by 33 guidings of set teat, being retracted into the 4th position 56 by the 3rd position 55 is again held, electronic cards was accommodated in this connector and fixed this moment, when moving back card, movable end 52 skips to the 5th position 57 by the 4th position 56 and is released, answer motive force by described spring 4, relative slide block 3, movable end 52 by the 5th position 57 again through the 6th position 58, turn back to initial condition through 34 guidings of set skew wall by the 7th position 59 again, move back the card cycle thereby form one.So, driving by inserting electronic cards 8, is to be fixed by guide rod 5 one ends fully, the other end and guidance part 32 skew wall faces 321 against and generation deformation, thereby produce to restore according to predefined paths, make the movable end 52 of guide rod 5 hold or be released to produce and move back the card effect by guidance part 32.

The height of this connector slide block can carry out slimming, can guarantee stability of structure fully, makes the card that moves back that retreat-card device can be well on, so since, the height of whole connector is minimized, thereby reduces the product height.

Practical case and accompanying drawing that the utility model is lifted, only for the utility model is illustrated, be to make and be familiar with purpose and the effect that this operator can understand the utility model strictly according to the facts, but the utility model there is not any restriction, the utility model also can still have other variation execution mode, so allly be familiar with this operator and carry out other pattern under this case utility model spirit and implement not breaking away from, the equivalence that all should be considered as this case claim is implemented.
