Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, relates in particular to a kind of electronic card coupler that makes the electronic cards plant and be electrically connected to circuit board.

[background technology]

The prior art relevant with the utility model can be with reference to No. the 575237th, Taiwan patent announcement, and the electronic card coupler of its announcement comprises insulating body, is contained in conducting terminal and trip mechanism in the insulating body.This insulating body definition has the plant space of an electronic cards, trip mechanism comprises elastic component and is slidedly arranged on the sliding part of this insulating body, one-body molded on this sliding part have a pushing part, when electronic cards is inserted the plant space and is contacted the pushing part, this pushing part drive sliding part slides on insulating body and the while compression elastic piece under the effect of electronic cards insertion force, finish with connector until electronic cards and to peg graft, when moving back card, the elastic component elastic recovery is also pushed sliding part to the electronic cards exit axis, drives electronic cards with integrated this pushing part of sliding part and withdraws from.When above-mentioned electronic cards is inserted electronic card coupler, the pushing part is born the electronic cards insertion force and is driven sliding part slip and compression elastic piece, if the electronic cards insertion force is bigger, the possibility that just there is fracture this pushing part itself or disconnects with sliding part, for addressing this problem, must strengthen sliding part itself and with the bonding strength of sliding part, the way that present industry is taked is to increase the thickness of pushing part and further increase the pushing part and the thickness of slide mass junction, but strengthened sliding part and with the bonding strength of sliding part in also increased itself size, be unfavorable for the miniaturization of product.

[utility model content]

The purpose of this utility model is to provide a kind of electronic card coupler, and its trip mechanism has enough structural strengths and bonding strength and helps miniaturization.

The purpose of this utility model is achieved through the following technical solutions: a kind of electronic card coupler, in order to electrically connect electronic cards, comprise: insulating body, trip mechanism, some terminals that can electrically contact and be contained in this insulating body with electronic cards with plant space, described trip mechanism comprises slide mass and can bear the electronic cards insertion force and can drive the press block that electronic cards withdraws from, wherein said press block is a metal structure, and this press block can be connected with described slide mass installation.

Compared with prior art, the metal press block of the utility model electronic card coupler is mounted to the plastic cement slide mass, by the mode of installing, bonding strength between press block and the slide mass can be strengthened greatly, and press block is originally as metalwork, its structural strength can be suitable with thicker plastic cement press block, because metal press block itself and and slide mass between the raising of bonding strength, reduced press block itself under the effect of electronic cards insertion force and and slide mass between rupture may, simultaneously, because do not need to increase thickness to improve intensity, press block can have less size.
