Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler.

[background technology]

In recent years, electronic cards is widely used in the field of information processing, is therefore a kind ofly arisen at the historic moment in order to the electronic card coupler of accepting card, and electronic card coupler is installed on the circuit board, the signal between transmission electronic card and circuit board.When this type of electronic card coupler of design, what need consideration is that electronic cards is being inserted in the electronic card coupler reliably than under the low insertion force.

United States Patent (USP) the 6th, 358,074,5,746,607,5,527,192,5,286, No. 957 grade has disclosed the electronic card coupler that is used for this field, the plurality of conductive terminals that those electronic card couplers include insulating body and are provided with along insulating body longitudinal axis direction.Wherein, the contact site of conducting terminal is sphere shape and is provided with to make things convenient for electronic cards to insert electronic card coupler from insulating body axis of pitch direction.But there is following defective in this structure: when electronic cards is inserted, because of conducting terminal is not provided with guiding device, the conducting terminal contact site directly contacts with electronic cards, and frictional force is bigger therebetween, so the user need apply than big active force and electronic cards can be inserted in the electronic card coupler.Moreover, when electronic cards is inserted, bearing bigger pressure from the nearest conducting terminal of electronic cards direction of insertion, this may cause conducting terminal to produce excessive distortion and can not return to original state, thereby makes the disabler of electronic card coupler.

[utility model content]

The utility model purpose is to provide a kind of and makes the convenient grafting of electronic cards, and can avoid the electronic card coupler of conducting terminal excessive deformation.

For achieving the above object, the utility model is by the following technical solutions: this electronic card coupler comprises insulating body and conducting terminal, wherein insulating body is longitudinal, which is provided with the terminal containing slot of accommodating conducting terminal, conducting terminal comprises contact site, its lateral margin extends laterally and is provided with guidance part, and the side fluting of accommodating guidance part is set on the insulating body.

Compared to prior art, advantage of the present utility model is: this electronic card coupler is taked the design of the laterally disposed guidance part of conducting terminal contact site lateral margin, when electronic cards is pegged graft, electronic cards contacts with guidance part in advance, by the guidance part guiding electronic cards is inserted in the electronic card coupler, the suffered insertion force of conducting terminal contact site when therefore helping reducing the electronic cards insertion, and the disabler that excessive deformation causes electronic card coupler can not take place owing to being subjected to bigger insertion force in the conducting terminal contact site.

[embodiment]

Please refer to shown in Figure 1ly, the utility model electronic card coupler 500 comprises insulating body 1 and several conducting terminals 3.Wherein, insulating body 1 is approximately longitudinal, comprise having upper and lower surperficial 113,115 main part 11 and accommodate the terminal containing slot 12 of conducting terminal 3 along several of main part 11 longitudinal axis direction settings, these terminal containing slot 12 lateral plans are the convex shape (see figure 3).Main part 11 also is provided with side fluting 13 near each terminal containing slot 12 place, and insulating body 1 is provided with sidewall 111 between terminal containing slot 12 and side fluting 13, further be provided with passage 131 on the sidewall 111.

Conducting terminal 3 comprises contact site 31, elastic portion 32, connecting portion 33 and weld part 34, wherein elastic portion 32 slightly becomes C shape, contact site 31 own elasticity portions 32 1 end bending extensions, connecting portion 33 own elasticity portions 32 other end horizontal-extendings, its bearing of trend is consistent with contact site 31 bearing of trends, and weld part 34 bends the back horizontal-extending from connecting portion 33 downwards away from an end of elastic portion 32.The contact site 31 of conducting terminal 3 is provided with the fin 311 that roughly becomes T shape, this fin 311 comprises long limit 313 and minor face 314, setting is extended on the long limit 313 of above-mentioned fin 311 on contact site 31, and its bearing of trend is consistent with the bearing of trend of contact site 31, the minor face 314 of fin 311 is to extend along the long limit 313 vertical directions of fin 311 to be provided with, the insulation of contact site 31 sides extends laterally guidance part 312 is set, and this guidance part 312 links to each other with the minor face 314 of fin 311.

Please refer to Fig. 2 and shown in Figure 3, the elastic portion 32 of conducting terminal 3 and connecting portion 33 are contained in the terminal containing slot 12 of insulating body 1, the upper surface 113 of termination contact portion 31 outstanding insulating body 1 main parts 11, guidance part 312 free ends are contained in the side fluting 13, the lower surface 115 of weld part 34 stressing main portions 11 and parallel with lower surface 115.

Please refer to shown in Figure 4, during use, electronic card coupler 500 is installed on the circuit board 9, when electronic cards 7 when insulating body 1 axis of pitch direction is inserted electronic card coupler 500, the guidance part 312 of conducting terminal 3 provides longer inclined-plane slowly to insert for this electronic cards 7, the elastic portion 32 stressed elastic compression of conducting terminal 3, guidance part 312 move down and are contained in the insulating body 1 side fluting 13.

The conducting terminal 3 contact sites 31 lateral margin side direction of the utility model electronic card coupler 500 are provided with guidance part 312, this guidance part 312 provides long inclined-plane to make electronic cards 7 in the insertion of walking unhurriedly along conducting terminal 3 vertical directions, reduce the suffered insertion force of contact site 31, thereby can not make the termination contact portion 31 of conducting terminal 3 that excessive deformation take place and make the disabler of electronic card coupler 500.

In the above-described embodiment, guidance part 312 only is arranged on contact site 31 1 sides, and the contact site opposite side also can be provided with guide portion to satisfy different needs certainly.Moreover each conducting terminal 3 contact site 31 is equipped with guidance part 312 in the above-mentioned execution mode, also can select part terminal 3 that guidance part 312 is set certainly and also can realize above-mentioned functions.
