Abstract

The utility model relates to an electronic card connector structure. The electronic card connector structure comprises an insulating body which is provided with a plurality of terminal containing ducts, and a plurality of conductive terminals. The utility model is characterized in that the contact parts of the conductive terminals are hooks with big curvature and small curvature, and the hooks are connected into integration by interconnecting pieces. The conductive terminals can be divided into two classes: long terminals and short terminals. The long terminals and the short terminals are arranged and assembled in the corresponding terminal containing ducts of the in insulating body in the alternate and opposite form. Therefore, a circuit board can be fixedly clamped by the conductive terminals of the electronic card connector. As a result the effects that the assembly is quick and the cost is reduced are achieved.

Description

The electronic card coupler structure

The utility model relates to a kind of electronic card coupler structure, refers to that especially a kind of terminal of electronic card coupler can insert and put mode and circuit board electric connection, and need not to establish in addition the electronic card coupler structure of changeover mechanism.

Electronic card coupler early adopts the through hole solder technology that its conducting terminal is welded on the circuit board, the defective of the method is apparent, both line constructions of destructible circuit board thereby influence its performance, fragile again its conducting terminal causes the unnecessary man-hour and the waste of raw material during winding, manufacture the table rising thereby make, so at present main adopt two kinds of patterns that are connected with circuit board are arranged, a kind of is the surface adhesion type, another kind switches through meet sb. at the airport structure or adaptor connector type for other.Adopt the conducting terminal of the existing electronic card coupler of surface adhesion technology generally to be provided with two row or multi-row, but its extend to circuit board one end then often and do one row or two rows, its conducting terminal then seems too intensive and has increased the technical difficulty that surface adhesion engages with the bonding end that engages of circuit board surface like this, make it be difficult for realizing a large amount of production, and be difficult to control the flatness of carrying out surface adhesion joint conducting terminal, make that its telecommunication quality of connection is difficult to guarantee.If take the way of changeover mechanism or adaptor connector, thereby then not only additionally set up outside member and processing procedure can raise the cost, also can increase its space shared on circuit board because of setting up changeover mechanism or adaptor connector.

The purpose of this utility model is to provide a kind of electronic card coupler structure, and this electronic card coupler structure has low cost of manufacture, saves the advantage in space, and can effectively reduce the grafting resistance.

On the electronic card coupler each conducting terminal that is characterised in that of the present utility model is at least the upper and lower row that one is long and the other is short disposes, and respectively arranging adjacent both ends arranges with long terminal and short terminal intervals respectively, the drop of deploying makes circuit board contact with upper and lower row's terminal with different time thus, thereby the resistance can effectively reduce electronic card coupler and circuit board and peg graft the time, and the contact jaw that contacts with circuit board is arranged to specific bending shape, make it and circuit board can be clamped, thereby need not extra auxiliary part and can finish winding with circuit board.

According to above-mentioned feature, the upper and lower row of electronic card coupler is corresponding, and to become the conducting terminal of row also to be configured to long and short conducting terminal relative, circuit board is contacted respectively with upper and lower row's terminal with different time, resistance in the time of can further disperseing electronic card coupler and circuit board to peg graft, thereby can effectively reduce relay.

The utility model utilize the special tectonic of conducting terminal can be directly and circuit board insert and put the winding one, the advantage of have low cost of manufacture, saving the space, and, conducting terminal utilizes its specific formation, contact with circuit board with different time points when making winding, thereby can effectively reduce the grafting resistance, and have winding rapidly, characteristics easily.

The utility model is described in further detail below in conjunction with drawings and Examples:
