Description

The driving and reversing mechanism of electric connector

[technical field]

The utility model relates to a kind of electric connector, is meant a kind of driving and reversing mechanism of electric connector especially.

[background technology]

At present aspect the mechanism design of electronic product, have the driving and reversing mechanism of hiding the location when inserting and exposing function when withdrawing from and be applied in electronic product and computer peripheral product widely, such as Multi Media Card or memory card or the like, the employed memory card of computer has plurality of specifications such as Secure Digital Card (being called for short SDC), Muti Media Card (being called for short MMC), Smart Media Card (being called for short SMC), Memory Stick Card (being called for short MSC), XD-PictureCard (being called for short XDC) at present on the market ... or the like.

The connector of the above-mentioned memory card of connection is hidden the location and is withdrawed from and exposes for the memory card that makes insertion can insert at present, be to be provided with an advance and retreat card device in it, see also Fig. 1 and Fig. 2, be a kind of known memory card connector with driving and reversing mechanism, it is provided with a pedestal 10, most terminal 25, a push jack 20, a guide bar 26, an and spring 28, wherein:

This pedestal 10 is to be covered by a base 11 and loam cake 19 to form, please cooperate ginseng Fig. 3, this base 11 is to be the plastics ejection formation, be provided with the storage tank 18 that to place several different size memory cards in it, the one-body molded chute 12 that is provided with of one side, this chute 12 is to be heart type, the one end is a starting point 13, and being one stroke point 14, one umbilicate anchor point 15 and, the other end moves back card starting point 16, form several skewbacks 17 on this chute 12, make by starting point 13 → travel point 14 → anchor point 15 → move back 13 one-tenth one unidirectional circulations of card starting point 16 → starting point.

This most terminal 25 is to become number row to be located on this base 11.

This push jack 20 is the ㄇ shape, and storage tank 18 both sides of closing on base 11 are supported in its both sides, and one side front end is provided with a connecting hole 21.

These guide bar 26 two ends all become hook part 27 longitudinally, and the one end colludes the connecting hole 26 in push jack 20, and the other end colludes the chute 12 in this base 11.

This spring 28 be positioned at push jack 20 and base 11 rear ends between, the elastic force that it is return after providing push jack 20 to move in pedestal 10 again.

By above structure, the memory card that is inserted when push jack 20 drives this guide bar 26 and slides in chute 12 when promoting, because this chute 12 be unidirectional circulation, 26 elder generations of guide bar are pushed into after the travel point 14 by starting point 13 that elastic force by spring retracts and the anchor point 15 that arrives is located again when memory card inserts; When moving back card, also push memory card, 26 of guide bars are pushed into the elastic force that moves back after the card starting point 16 again by spring by anchor point 15 and retract and get back to starting point 13, so can reach the function of advance and retreat card.

Known be configured with following shortcoming, that is:

1. push jack 20 is to be plastics ejection formation person, plastic material intensity difference and be subjected to external force easily and accidentally fracture.

2. push jack 20 does not design with pedestal and does to engage slip, for push jack 20 can steadily be assembled in the pedestal, can steadily be placed on the base 11 and compress the location by loam cake again so need that push jack 20 is designed to the ㄇ shape, yet many and plastic material is fragile is more prone to fracture except materials used when push jack is designed to the ㄇ shape.

3. push jack 20 is to be positioned base 11, if base 11 is divided into most stromas when floating with respect to loam cake respectively, then push jack just can't be positioned on can several unsteady stromas.

4. this push jack and spring are to put to be assembled on the base 11, cover the location by loam cake again, so aptitude test advance and retreat effect after product needs overall package to finish if product test is defective, then need be pulled down reorganization or whole the calcellation.
