Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, refers in particular to a kind of electronic card coupler with improved trip mechanism.

[background technology]

Electronic card coupler is widely used in and connects electronic cards and electronic equipment.Corresponding multimedia card (Multimedia Card) and safe digital card (Secure Digital Card) volume is less, moving back card is difficult for, the connector of this type of electronic cards generally is provided with retreat-card device and assists to move back card, announce 2.5mm Pitch Multimedia Card Connector in the product catalog as Mo Liesi (Molex) company's site, just be provided with retreat-card device, after inserting electronic cards, again electronic cards is pushed away forward, can realize moving back card.

The electronic card coupler that Japan special permission publication 2000-251024 number, 2000-251025 number, No. the 6332791st, United States Patent (USP) and U.S.'s publication application disclose for 2001/0055896A1 number is equipped with similar retreat-card device.With U.S.'s publication is for 2001/0055896A1 number example, please refer to shown in Figure 4ly, and the retreat-card device of electronic card coupler 200 is included in heart type cam 66, slide bar 64, actuated slider 63 and the spring 62 that insulating base 60 side arms 61 upper surfaces are arranged with.Wherein actuated slider 63 front ends extend laterally actuation part 67 are set.Spring 62 front ends are fixed on the insulating base 60, and spring 62 rear ends link to each other with actuated slider 63 front ends, and actuated slider 63 rear ends and slide bar 64 front ends link together, and slide bar 64 rear ends place in heart-shaped cam 66 guide groove (not label) on every side.When inserting electronic cards (not icon), the electronic cards front end is against the actuation part 67 of actuated slider 63, promoting actuated slider 63 and slide bar 64 together moves forward, slide in the guide groove around the heart-shaped cam 66 in slide bar 64 rear ends, spring 62 compressions are also accumulated restoring force, after electronic cards was inserted fully, slide bar 64 rear ends were positioned at the latched position C of heart-shaped cam 66.When moving back card, promote electronic cards forward, slide bar 64 rear ends are withdrawed from from heart-shaped cam 66 latched position C, spring 62 discharges restoring force, the actuation part 67 that drives actuated slider 63 ejects electronic card coupler 200 with electronic cards, and slide bar 64 retreats to off-position D, moves back card motion thereby finish.But the heart-shaped cam 66 of this trip mechanism is located at the upper surface of insulating base 60 side arms 61, has increased the width of electronic card coupler 200, takies electronic equipment than large tracts of land.Slide bar 64 adopts hinged or one-body molded mode with being connected of actuated slider 63 simultaneously, and operation is comparatively complicated, is unfavorable for saving cost.

Electronic card coupler 300 as shown in Figure 5, trip mechanism comprise spring 71, actuated slider 73 and slide bar 74, and actuated slider 73 1 sides are concaved with guide groove 72, and guide groove 72 rear portions are provided with latched position E.Spring 71 rear ends are fixed on the housing 70, and front end links to each other with actuated slider 73 rear ends, and slide bar 74 front ends are fixed together with integrated mode and insulating base 75.The effect of the effect of guide groove 72 and aforementioned heart-shaped cam 66 is roughly the same, slide bar 74 rear ends are held in the latched position E of guide groove 72 after inserting electronic cards, when moving back card, promote electronic cards forward, slide bar 74 rear ends skid off latched position E by the restoring force of spring 71, get back to guide groove 72 front ends.This defective that has overcome above-mentioned increase electronic card coupler width by the structure that guide groove 72 is located at actuated slider 73 sides, but slide bar 74 and insulating base 75 one-body molded settings, need an ad hoc cover integrated mould, and this one-body molded operation is comparatively complicated, is unfavorable for saving cost.

The trip mechanism of the electronic card coupler that Japan's special permission publication is disclosed for 2001-085089 number and the trip mechanism of electronic card coupler shown in Figure 5 300 are roughly the same, slide bar wherein is not to be connected with insulating base in integrated mode, but be fixed together with pin riveted way and insulating base, it is bigger that but this affixed mode not only takes up space, and production process is also very complicated.

[utility model content]

The utility model purpose is to overcome the prior art defective, and the electronic card coupler of a kind of processing procedure trip mechanism simple with low cost is provided.

The utility model electronic card coupler comprises insulating base, organizes the trip mechanism that is located at plurality of conductive terminals, the shielding casing on the insulating base and is assembled in insulating base one side.Wherein insulating base one end is provided with location notch, and the corresponding end of shielding casing is provided with the fixing pin.Trip mechanism comprises spring, actuated slider and slide bar, and the actuated slider side is provided with guide groove, and slide bar one end places in the guide groove of actuated slider, and the other end is housed in the location notch, and is positioned in the location notch by the fixing pin of shielding casing.

Compared to prior art, the slide bar of the utility model trip mechanism is retained on the insulating base by shielding casing, is easy to processing, thereby provides cost savings.
