Description

Electronic card coupler

The utility model relates to a kind of electronic card coupler, refers in particular to a kind of electronic card coupler with electronic cards and circuit board electric connection.

Generally be electrical connected by electronic card coupler between electronic cards and circuit board, the some of them electronic card coupler is provided with arrangement for detecting and is used for detecting electronic cards and whether has been inserted into the tram.Relevant prior art can be with reference to United States Patent (USP) the 5th, 334,034,5,370,544,6,027,350 and 6,086, No. 426, the electronic card coupler arrangement for detecting that these prior aries disclosed generally includes one and moves a terminal and a fixed terminal, and wherein fixed terminal one end welds mutually with the first switch pad of being located at the circuit board that electronic card coupler assembles, and mobile terminal welds mutually with circuit board second switch pad.When electronic cards is not inserted to the location, originally mobile terminal is in fixed terminal and contacts/off-state, after electronic cards is inserted into the tram, utilize the electronic cards leading edge to compress mobile terminal and make mobile terminal and fixed terminal become disconnection/contact condition, whether have been inserted into the tram thereby reach the detecting electronic cards.But owing to adopt the separate type setting between fixed terminal and mobile terminal, therefore need use different moulds to make and unfavorable reduction mould and manufacturing cost respectively in the mill, and when assembling, also need assemble respectively and be unfavorable for improving efficiency of assembling.Simultaneously, its fixed terminal and mobile terminal one end all are connected with the corresponding switch pad of circuit board by welding, so need increase welding sequence in the mill and also be unfavorable for improving efficiency of assembling.

The utility model purpose is to provide a kind of whether switch terminal of being convenient to make and assemble has been inserted into the tram with the detecting electronic cards electronic card coupler that has.

The purpose of this utility model is achieved through the following technical solutions: the utility model includes insulating body, group is located at conducting terminal and switch terminal in the insulating body; Wherein switch terminal is the single-piece setting, comprises two elastic arms, and wherein each elastic arm is equipped with contact site and support division.When electronic cards is inserted, electronic cards leading edge pushing elastic arm support division, the elastic arm contact site moves down and is connected with first, second switch pad of circuit board respectively simultaneously.

Compared to prior art,, only need a mold when therefore making 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, can once directly organize and be located on the insulating body, not be beneficial to and enhance productivity thereby need not carry out welding sequence.

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

Fig. 1 is partial exploded view of the present utility model and concerns schematic diagram with the relevant position of electronic cards, circuit board.

When Fig. 2 was not inserted into the final position for the framework when the carrying electronic cards, the position of the utility model and circuit board and electronic cards concerned schematic diagram.

When Fig. 3 is inserted into the final position for the framework when the carrying electronic cards, the action schematic diagram of the utility model and circuit board and electronic cards.

Please refer to shown in Figure 1ly, the utility model electronic card coupler 1 comprises insulating body 10, conducting terminal 20, switch terminal 30 and framework 40.Wherein insulating body 10 comprises main part 100 and holding parts 120, aforementioned body portion 100 vertical two ends are provided with the terminal containing slot 101 that several run through main part 100 upper and lower surfaces, then are concaved with the chute 102 that extends with insulating body 10 parallel longitudinals at first lateral margin 103 and second lateral margin, 104 bottoms.Holding parts 120 extends setting from main part 100 first lateral margins 103 along main part 100 longitudinal directions, and holding parts 120 ends are provided with the projection 121 that a restriction electronic cards 5 is inserted into the final position, the upper surface of these projection 121 protrusion holding parts 120.Holding parts 120 is concaved with a recess 122 in projection 121 1 sides, and described recess 122 inboards are provided with the draw-in groove of offering to main part 100 inside along insulating body 10 longitudinal axis 123.Simultaneously, holding parts 120 contiguous recesses 122 places are provided with an opening 124 that is connected with draw-in groove 123.

Switch terminal 30 is made by the whole punching press of metal material, comprise two in the same way bending extension elastic arm 300 and connect the holding section 310 of two elastic arms 300.Above-mentioned two elastic arms 300 are provided with the arc support division 301 that protrudes holding section 310 upper surfaces at an end that is connected with holding section 310, then are provided with the contact site 302 that is the overhead kick shape at free end.310 middle parts, holding section are provided with protrusion holding section 310 upper surfaces and relative holding section 310 is the retaining sheet 320 that extend at certain inclination angle.

Framework 40 probably is "  " shape, comprise first, second relative sidewall 401,402 and connect the connecting wall 403 of first, second sidewall 401,402, first, second sidewall 401,402 tops are provided with groove 404 and accommodate the reception room 405 of electronic cards 5 with formation, and the bottom then convexes with slide rail 406 in opposite directions to above-mentioned reception room 405 inside.
