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 circuit board, and whether fully most of electronic card coupler is provided with arrangement for detecting to detect electronic cards insertion by electronic card coupler.Relevant prior art can be consulted United States Patent (USP) the 5th, 334,034,5,370,544,6,027,350 and 6,086, shown in No. 426, the arrangement for detecting that these prior aries disclosed generally includes one and moves a terminal and a fixed terminal, and originally mobile terminal is in fixed terminal and contacts/off-state, and after electronic cards was inserted, electronic cards leading edge or lateral margin compressed mobile terminal, make mobile terminal and fixed terminal become disconnection/contact condition, thereby whether the detecting electronic cards is inserted fully.But, because this arrangement for detecting has two terminals, need during fabrication to make respectively and be unfavorable for reducing mould and manufacturing cost, and when assembling by different moulds, need assemble respectively and be unfavorable for enhancing productivity.And for example United States Patent (USP) the 6th, 130, shown in No. 387, though it discloses a kind of design with single type detecting terminal, but its detecting terminal is housed in the insulator foot fully, makes insulator foot oversize, is unfavorable for reducing insulator foot shared area on circuit board.

Whether the utility model purpose is to provide that a kind of volume is less has an electronic card coupler of being convenient to the switch terminal making and assemble, insert fully with the detecting electronic cards.

The purpose of this utility model is achieved through the following technical solutions: a kind of electronic card coupler, comprise insulator foot, plurality of conductive terminals and switch terminal, wherein have some reception rooms on the insulator foot, conducting terminal is housed in the above-mentioned reception room, insulator foot one side is provided with an accepting groove in addition, this accepting groove and reception room be arranged in parallel to accommodate switch terminal, this switch terminal is the single-piece setting, the one end is provided with weld part and the first switch contact mat butt that is located on the circuit board, the other end is provided with abutment arms and contact arm relatively, after electronic cards is inserted, electronic cards presses down the abutment arms of protruding the insulator foot upper surface, contact arm is moved down and with circuit board on the electrical butt of second switch contact mat, whether insert fully with the detecting electronic cards.

Compared to prior art, switch terminal of the present utility model is the single-piece setting, and can once be made by punch forming, only needs a mold when making like this and can reduce die cost.And, can once directly organize to be located at and be beneficial on the insulator foot enhance productivity in when assembling.In addition, accepting groove is positioned at insulator foot one side, and be arranged in parallel with reception room on the insulator foot, pedestal needn't be set in addition accommodating switch terminal, thereby can reduce the volume of electronic card coupler and the area of shared circuit board.

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

Fig. 1 is that switch terminal, the group of the utility model first embodiment is provided with the location resolution schematic diagram between insulator foot, electronic cards and the circuit board of conducting terminal.

Fig. 5 is the switch terminal of the utility model second embodiment, the three-dimensional exploded view that group is provided with insulator foot, electronic cards and the circuit board of conducting terminal.

Fig. 6 is the assembling schematic diagram of embodiment and circuit board as shown in Figure 5.

See also Figure 1 and Figure 2, the utility model electronic card coupler 1 comprises insulator foot 10, conducting terminal 11 and switch terminal 12.Wherein insulator foot 10 is provided with some reception rooms 100, and insulator foot 10 1 sides are provided with and the parallel accepting groove 101 of described reception room 100 bearing of trends, this accepting groove 101 is communicated with insulator foot 10 axial two ends, and in accepting groove 101, be provided with projection 102, and on the two side of accepting groove 101, offer draw-in groove 103.

Conducting terminal is located in the reception room 10 for 11 groups, the contact site 110 that is located at conducting terminal 11 1 ends protrudes insulator foot 10 upper surfaces to contact with electronic cards 2, and be located at first weld part 111 of the relative other end, be welded on the circuit board 3 of insulator foot 10 belows, can make like this between electronic cards 2 and the circuit board 3 and form path.

Switch terminal 12 is made by the whole punching press of metal material, comprise Fixed Division 120, second weld part 122 and elastic portion 123, described Fixed Division 120 1 ends are extended with first connecting portion 124 to direction bending and are connected with second weld part 122, and the other end bends to the opposite direction of above-mentioned direction and is extended with second connecting portion 125 and is connected with elastic portion 123.In addition, 120 both sides, described Fixed Division respectively are outward extended with ratchet 121.When 12 groups of switch terminals are located in the accepting groove 101, are mounted in by ratchet 121 in the draw-in groove 103 of above-mentioned insulator foot 10, thereby switch terminal 12 firm groups are located on the insulator foot 10.And the lower surface that second weld part 122 of switch terminal 12 protrudes insulator foots 10 with solid welding on the first switch contact mat 31 on the circuit board below the insulator foot 10 3.Elastic portion 123 1 ends are connected with second connecting portion 125, and the other end then extends and is bent with arc abutment arms 126, these abutment arms 126 both sides along abutment arms 126 bearing of trends and relatively the reverse bending of abutment arms 126 overbending directions be extended with arc contact arm 127.After 12 groups of switch terminals are located in the accepting groove 101 of insulator foot 10, the end lower surface that elastic portion 123 links to each other with second connecting portion 125 is fitted on projection 102 end faces, the relative other end then is unsettled and is arranged in the accepting groove 101, and abutment arms 126 and contact arm 127 protrusion insulator foots 10 front ends.

See also shown in Figure 3ly, when electronic cards 2 was not inserted fully, the abutment arms of switch terminal 12 126 was protruded insulator foots 10 upper surfaces, and contact arm 127 does not contact with circuit board 3.When electronic cards 2 was inserted fully, electronic cards 2 leading edges pressed down abutment arms 126, and contact arm 127 contacts with second switch contact mat 32 on being located at circuit board 3, is connected (as shown in Figure 4) with corresponding detection circuit on the circuit board 3.Like this, form path, whether insert fully with detecting electronic cards 2 thereby make between first, second

switch contact mat

31,32 by switch terminal 12.

Fig. 5 and Fig. 6 are second embodiment of the present utility model, compare with first embodiment, its difference is that the abutment arms 131 on the switch terminal 13 is to be bent into arc and to be formed by whole extension of elastic portion 130, and is one circular-arc in abutment arms 131 terminal bendings, to form contact arm 132.Insulator foot 10 upper surfaces are protruded on abutment arms 131 tops when not inserting electronic cards 2, after electronic cards 2 is inserted fully, electronic cards 2 leading edges press down abutment arms 131 moves down contact arm 132, and then makes the second switch contact mat 32 electrical butts on contact arm 132 and the circuit board 3.
