Description

Electronic card coupler

The utility model relates to a kind of electronic card coupler, is meant especially a kind ofly to move back card with two-part, and moves back card and operate electronic card coupler easily.

With the miniaturization and the multifunction of computer, existing computer all disposes the electronic card coupler of planting for storage card, I/O card.Relevant patent case can reach United States Patent (USP) the 4th, 818,239,4 with reference to No. the 80207449th, 81216447,81217278,82205600,83202199,83107162,8328140, Taiwan patent application, 878,856,4,810,203,5,085,590,5,149,276,5,176,523,5,286,207,5,290,174,5,324,204 and 5,334, No. 046 etc.But above-mentioned existing electronic card coupler all exists jointly and remains improved shortcoming, and promptly it moves back the card inconvenient operation.See also Fig. 1, the trip mechanism 5 of existing electronic card coupler comprises guide rod seat 50, liftout plate 51, rocking bar 52, cover plate 53 and push rod 54, wherein this guide rod seat was located at the both sides of inserted terminal 601 of the insulating base frame 60 of connector 6 in 50 minutes, can with the holding arm 602 cover card connection one of both sides.And this liftout plate 51 is located between the two guide rod seats 50, and an end is articulated by rocking bar 52, and the other end is for ejecting end.One end of this rocking bar 52 and push rod 54 articulate, and relative the moving of the promotion of drawn stem 54.This push rod 54 is located in the guide rod seat 50 of a side, and the one end is provided with press button 501, and tractional force can be provided, and pushes this press button 501 when moving back card, push rod 54 can be moved vertically, makes rocking bar 52 interlock liftout plates 51 ejections operation.

Yet because whole electronic card coupler sees also shown in Fig. 2 A with concealed a jiao of being housed in portable computer, when not planting electronic cards 8, the press button 501 of this push rod 54 is inboard shell 7; And after inserting electronic cards 8, shown in Fig. 2 B, though press button 501 is ejected and is positioned at than the outside, but still may be positioned at the inboard of shell 7, this is because when inserting electronic cards 8, the only rough interlock distance (general about 3 to 6mm) that equals between electronic cards and liftout plate of the displacement of push rod 54 and press button 501.Finger still may must stretch in the computer casing 7 when therefore moving back card, and with the press button 501 of pushing this push rod 54, this action not only is not easy on the application of force, neither be very convenient in the operation, and easy mistake is pressed onto the electronic cards 8 of next-door neighbour's press button 501.

The purpose of this utility model is to provide a kind of electronic card coupler, when moving back card, the push rod in the trip mechanism can be protruded in outside the housing by being housed in to become in the portable computer housing, can finger need not be stretched in the housing and push easily by the outer directly pressing operation of housing.

Another purpose of the present utility model is to provide a kind of electronic card coupler, and during with plug-in card not, the push rod of trip mechanism can not released by interlock, all is positioned at the portable computer housing at plug-in card.

The purpose of this utility model is achieved in that promptly provides a kind of electronic card coupler, and it is assembled on computers, and it comprises: an insulating base frame, which is provided with the terminal accommodating district, and described accommodating area has inserted terminal and welding ends; Several conducting terminals are installed with in described terminal accommodating district, have inserted terminal and welding ends; One trip mechanism, be located at the inserted terminal of described insulating base frame, at least comprise guide rod seat, liftout attachment and push rod, wherein said guide rod seat is located at the inserted terminal both sides of described insulating base frame, described push rod is located in the guide rod seat of a side, and it has the pushing end that promotes described liftout attachment and ejection electronic cards vertically; One location guiding device is located between described guide rod seat and the described push rod, and it guides described push rod to move axially, and the pushing end of locating described push rod is positioned at the primary importance of approaching described insulating base frame and is positioned at the second place away from described insulating base frame.

The advantage of the utility model device is that it can move back the card operation directly pushing of the computer casing outside, and processing ease is convenient, and safe and reliable, practicality is good.Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
