Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, refers to especially a kind ofly electronic cards and circuit board are electrically connected and can guarantee that electronic cards correctly pegs graft and prevent the improper electronic card coupler of extracting.

[background technology]

Along with communication and development of computer, increasing electronic cards is devised to satisfy different needs, and therefore, the electronic card coupler that is used to electrically connect electronic cards and circuit board arises at the historic moment.For guaranteeing that electronic cards correctly is plugged in the electronic card coupler, electronic cards is provided with the oblique angle mostly, and electronic card coupler moves back and is provided with the oblique parts that cooperate with this oblique angle in the card thrust unit.When the electronic cards mistake was pegged graft, because of the existence of oblique parts, electronic cards is terminal can can't be inserted in the electronic card coupler and make electronic cards can't be inserted to the location, and Xiang Guan prior art can be consulted the flat 11-66247 of Japanese laid-open patent TOHKEMY number etc. therewith.Though this kind structure can guarantee electronic cards and dock with the final of electronic card coupler, but during the grafting electronic cards, the user generally has electronic cards oblique angle one end and inserts in advance, and the relative electronic card coupler in this oblique angle still can't be judged on the right side in the left side, this kind situation all has the situation of contact mat more complicated to the electronic cards both sides, so when the electronic cards mistake is pegged graft, the electronic cards leading edge can butt the contact jaw of electronic card coupler conducting terminal, easily cause conducting terminal excessively to be pressed down or can't be resiled by jack-up and make electronic card coupler destroy.In addition, when the user pulled out card accidentally in the course of the work, electronic cards can break away from electronic card coupler, the situation that causes the data that is stored in electronic cards to lose.

[summary of the invention]

The purpose of this utility model is to provide a kind of and guarantees that electronic cards correctly pegs graft, has the electronic card coupler that anti-mis-insertion/mistake is pulled out function.

The purpose of this utility model is achieved in that the utility model comprises insulating body, be mounted on the conducting terminal in the insulating body, be located at the trip mechanism and the anti-mis-insertion/mistake of insulating body one side and pull out member, wherein anti-mis-insertion/mistake is pulled out member and is comprised and be located at the elastic arm on the trip mechanism respectively and be located at discontinuous first fin in the insulating body, second fin and be located at first fin and second fin between interval trough, according to the plug-in card correctness, described elastic arm alternative is placed in the interval trough, and then cooperates the control trip mechanism could continue to move along the plug-in card direction with interval trough.In addition, when the user pulled out card accidentally in the course of the work, the lateral margin of electronic cards can compress the abutting part of elastic arm, and the end of elastic arm bumps against second fin, and this moment, card space is not enough can be prevented from electronic cards is taken out of because of moving back, thereby reached anti-function of extracting.

Compared with prior art, advantage of the present utility model is: that anti-mis-insertion/mistake is pulled out element structure to the utility model is simple, quite easy in the manufacturing, and owing to utilize original mechanism, does not need additionally to take up space more, and assembly manipulation is simply quick.

Trip mechanism is located at for 5 groups in the receiving space 231 of accommodating arm 23, comprises roughly L-shaped slide block 60, body 51 and the trace 64 that cooperates control slide block 60 to locate with body 51.Slide block 60 is provided with supporting arm 61 and is located at supporting arm 61 1 ends and is the trapezoidal arm 65 that supports.Wherein, the upper surface of supporting arm 61 offers a roughly V-shaped wedge groove 63, be provided with projection 633 in the wedge groove 63, and supporting arm 61 bottom surfaces is provided with chute 611, supporting arm 61 sides 613 vicinities support arm 65 ends and are provided with groove 615, and adjacent recess 615 places are provided with breach 617.Support arm 65 upper surfaces and be provided with first groove 651 and second groove 653, in the plug-in card process, preventing and conducting terminal 4 is interfered, and be provided with in the inboard and cooperate inclined-plane 655 and supporting surface 657.

Anti-mis-insertion/mistake is pulled out member 6 and is arranged on insulating body 2 one sides, in the present embodiment, anti-mis-insertion/mistake pull out member 6 comprise be located at discontinuous first fins 236 in the receiving space 231, second fin 238 and therebetween proper width interval trough 237 and be located at elastic arm 62 on trip mechanism 5 slide blocks 60.Wherein elastic arm 62 comprises the holding parts 621 that is mounted in supporting arm 61 grooves 615, extends from the vertical bending of holding parts 621 1 ends and along supporting arm 61 sides 613 and the connecting portion 623 established and be located at connecting portion 623 free-ended arc abutting parts 625.Described arc abutting part 625 ends stretch into the bottom that supporting arm 61 has chute 611 by supporting arm 61 breach 617, and arc abutting part 625 upper limbs exceed side 613.

Electronic cards 3 one sides that dock with the utility model are provided with a component, are a notch 30 in the present embodiment, and the electronic cards front end is provided with an oblique angle 31 with the homonymy that notch 30 is set.

Extremely shown in Figure 7 as Fig. 5, not during plug-in card, body 51 is housed in accommodating on the post in the spring guide groove, the one end supports that the other end then connects with slide block 60 1 sides on the substrate 21 of insulating body 2, be in release condition, slide block 60 is contained in insulating body 2 receiving spaces 231, and first fin 236 and second fin 238 are contained in slide block 60 chutes 611, trace 64 1 ends are arranged in the groove shape track 239, the other end is fixed in accommodates in the wall 23, and trace 64 can drive slide block along

first fin

236 and 238 slips of second fin when groove shape track 239 certain tracks are slided.

When inserting electronic cards 3, because of the notch 30 of electronic cards 3 abutting part 625 with elastic arm 62 fastens, and the oblique angle 31 of electronic cards 3 with support arm 65 cooperate supporting surface 657 butts, promote electronic cards 3 like this and drive supporting arm 61 and together move, this moment is because of not crimp of elastic arm 62, abutting part 625 does not fall in the interval trough 237 between two tracks, and supporting arm 61 moves along conducting terminal 4 one ends of plug-in card direction to electronic card coupler like this, until electronic cards 3 location.

If when plug-in card, mistake is with electronic cards Rotate 180 degree accidentally, the lateral margin that advances electronic cards 3 in the card process can be pressed onto the abutting part 625 of elastic arm 62, thereby force abutting part 625 ends to fall in the interval trough 237 of insulating body 2, can allow the user feel obviously to be obstructed when pushing away card, pull out effect thereby reach anti-mis-insertion/mistake.In addition, in the course of the work, when the user pulls out card accidentally, the lateral margin of electronic cards 3 can compress the abutting part 625 of elastic arm 62, make the end of abutting part 625 bump against second fin 238, this moment, card space is not enough can be prevented from electronic cards 3 is taken out of because of moving back, thereby reached anti-function of extracting.
