Description

Electronic card coupler

The utility model is a kind of electronic card coupler, relates in particular to a kind ofly to have positioner and by its electronic card coupler that can position the particular elements in the trip mechanism.

The design relevant with this case please refer to No. the 85103753rd, TaiWan, China patent application etc., wherein in the design of these existing electronic card couplers, its trip mechanism includes push rod, is connected with push rod one end and is the folding force section that 90 degree can freely bend, and is connected to be used for withdrawing from the ejecting mechanism of electronic cards with the push rod other end.Wherein push rod is arranged in the track set on this electronic card coupler sidewall, and when when moving back card, this push rod can be under the effect of external force and slide in orbit, and then drives ejecting mechanism and rotate action and borrow its end to withdraw from electronic cards.Yet, in the process that reality is made, this type of has the chute by direct setting on the electronic card coupler sidewall to be constituted in order to the track of accommodating push rod, also by being formed by the through hole on the projection of sidewall ejection formation, no matter be to slide or the formed track of through hole, the mismatch error that has a certain size between itself and push rod inevitably, thereby, after the electronic card coupler assembling, it will cause push rod because of the influence of this mismatch error and with respect to track to a certain degree crooked take place with the affixed force section of this push rod one end, and this crooked phenomenon can't be improved by other any structure.Thereby, in moving back the process of card, this push rod and force section thereof will produce with respect to track frequently and rock unstable situation, make the active force that moves back card usefulness move back the card application of force because of being difficult for aligning to increase, in addition, rocking and also will produce the sound or cause abrasion even the fracture that blocks the top situation improperly and then cause associated components frequently.

One of the utility model purpose is to provide a kind of and push rod on the trip mechanism is suitably located and then make the electronic card coupler that moves back card stroke all-the-time stable unanimity by positioner.

Another purpose of the present utility model is to provide a kind of electronic card coupler that the push rod on the trip mechanism is positioned the active force that push rod is applied when reducing to move back card by positioner.

Another purpose of the present utility model is to provide a kind of push rod on the trip mechanism being positioned to reduce this push rod by positioner to produce the electronic card coupler that rocks, sends situations such as the sound and wearing and tearing.

The purpose of this utility model is to realize like this, this electronic card coupler includes insulating body, be fixed in several conducting terminals on the insulating body, be shielded in the shielding casing in the insulating body outside and be located at trip mechanism on the one sidewall and structure such as positioner, wherein trip mechanism include push rod, with affixed force section of push rod one end and the rotary ejecting mechanism that is connected with the push rod other end, the turn by this ejecting mechanism gets final product the electronic cards that will dock with conducting terminal and withdraws from.Positioner then includes matrix and reaches in order to this matrix is fixed in the Fixed Division on the shielding casing sidewall, wherein matrix can be accommodated the location to push rod, and deflection, loosening does not take place so that this push rod bears against in the process of start on the sidewall of shielding casing all the time.

Compared with prior art, the utlity model has following advantage:

1. push rod on the trip mechanism is born against in the process of start on the sidewall of shielding casing all the time and deflection, loosening does not take place.

2. can reduce in moving back the card process active force to push rod applied.

3. can reduce push rod produces in moving back the card process and rocks, sends situations such as the sound and wearing and tearing.
