Description

Electronic card coupler

The utility model relates to a kind of electronic card coupler, especially refers to a kind of electronic card coupler that is used for electronic cards and circuit board electric connection.

Often realize being electrical connected between electronic cards and the circuit board by electronic card coupler, and the some of them electronic card coupler be provided with switching device with the detecting electronic cards whether be inserted into the final position, relevant prior art can be consulted United States Patent (USP) the 5th, 334,034,5,370,544,6,027,350 and 6, shown in 086, No. 426.In these prior aries, switching device includes one and moves a terminal and a fixed terminal, and originally be between mobile terminal and fixed terminal and contact/off-state, after electronic cards is inserted, the electronic cards leading edge compresses mobile terminal and makes mobile terminal and fixed terminal become disconnection/contact condition, thereby whether the detecting electronic cards has been inserted into the final position.But these terminals adopt separate type settings, need during fabrication to make respectively by different moulds to be unfavorable for reducing mould and manufacturing cost, and when assembling, need assemble respectively and are unfavorable for improving efficiency of assembling.

The utility model purpose is to provide a kind of electronic card coupler of being convenient to the switch terminal making and assemble that has.

The purpose of this utility model is achieved through the following technical solutions: the utility model comprises insulator foot, plurality of conductive terminals, framework and switching device, wherein said frame is provided with accepting groove in order to accommodate electronic cards, and framework one side is provided with push rod, switching device includes switch terminal at least and is located at the first switch pad and the second switch pad in order to match with switch terminal on the circuit board, this switch terminal one end and the first switch pad electrically connect, and the other end is provided with abutting part and contact site relatively.When the framework that promotes to be installed with electronic cards moves to electronic cards and conducting terminal on the described electronic card coupler contacts, the abutting part of pushrod actuation switch terminal, thus make contact site rotation and electrically connect with the detecting electronic cards whether be inserted into the final position with the second switch pad of circuit board.

Compared to prior art,, like this, only need a mold during manufacturing and can reduce die cost because switch terminal of the present utility model is the single-piece setting, and can once be made by punch forming; And in when assembling, switch terminal can once directly be organized and be located on the insulator foot and be beneficial to and enhance productivity.

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

Fig. 1 be three-dimensional exploded view of the present utility model and and electronic cards, circuit board between the position concern schematic diagram.

Fig. 2 is an electronic cards when not being inserted into the final position as yet, and the mutual alignment concerns schematic diagram between each member of the utility model.

Fig. 3 is when electronic cards has been inserted into the final position as shown in Figure 2, three-dimensional combination figure of the present utility model.

See also shown in Figure 1ly, the utility model electronic card coupler 1 comprises insulator foot 10, plurality of conductive terminals 11, framework 12 and switching device 13.Wherein insulator foot 10 vertical two ends are provided with some reception rooms 100, be used to accommodate conducting terminal 11, and bottom, insulator foot 10 both sides are provided with the chute 101 parallel with insulator foot 10 longitudinal axis.In addition, insulator foot 10 1 distolateral edge are provided with a projection 102 along the extension of insulator foot 10 longitudinal axis, and middle part, above-mentioned projection 102 upper and lower surface is concaved with groove 103, and projection 102 upper surfaces are higher than insulator foot 10 upper surfaces.

Framework 12 summarys are " ㄇ " shape, comprise first, second relative sidewall 120,121 and connect the connecting wall 122 of first, second sidewall 120,121, first, second sidewall 120,121 tops are provided with groove is accommodated electronic cards 2 with formation accepting groove 123, the bottom is then extended in opposite directions to above-mentioned accepting groove 123 inside and is provided with slide rail 124, and the ends that the first side wall 120 is connected with connecting wall 122 relatively are provided with from the outward extending push rod 125 of the first side wall.

Switching device 13 comprises retaining piece 130 and switch terminal 134, and wherein retaining piece 130 is the metalwork that a cross section is " ㄈ " shape, comprises connecting portion 131, bends weld part 132 and the Fixed Division 133 that is vertical setting with connecting portion 131 from connecting portion 131 two ends.Switch terminal 134 comprises abutting part 135 and contact site 136.In the present embodiment, retaining piece 130 is to be bent into by the whole punching press of metal material with switch terminal 134, wherein the abutting part 135 of switch terminal 134 be connecting portion 131 lateral margins from retaining piece 130 outwards bend extend curved, contact site 135 is located at contiguous abutting part 135 terminal positions, and extend to inferior division from abutting part 135, and contact site 136 terminal bendings are arc.
