[embodiment]

See also Fig. 1 to shown in Figure 6, it discloses the utility model electronic card coupler 100, be used to accommodate rectangle and L shaped two kinds of electronic cards, it comprises insulating base frame 1, be contained in conducting terminal 4 in the insulating base frame 1, be covered in the shield shell 2 on the insulating base frame 1, the trip mechanism 5 that is installed on insulating base frame 2 and bonding pad 8, and is housed in the guide rail 7 in the shield shell 2.

Insulating base frame 1 is provided with a base portion 10, the support arm 12 that extends in the same way respectively from base portion 10 left and right sides and extends in the middle of base portion 10 and the hyoplastron 11 between described support arm 12.Be provided with some grooves 110 of wearing that can supply conducting terminal 4 to wear in described base portion 10 and the hyoplastron 11.Described support arm 12 be formed with respectively that guiding rectangle and L shaped electronic cards are inserted and with hyoplastron 11 guiding groove 120 at interval.In the described electronic cards insertion process, mat guiding groove 120 guiding is inserted, make it with hyoplastron 11 in conducting terminal 4 electrically connect, and hyoplastron 11 is housed in electronic cards and connects in the cavity that end forms.In the present embodiment, the contact site 40 of conducting terminal 4 is contained in wearing in the groove 110 of hyoplastron 11, and fixing with insulating base frame 1 by holding parts 41, roughly is vertical weld part 42 with contact site 40 in addition, in order to weld with preinstalled circuit plate (not shown).

In addition, extending internally from base portion 10 and a support arm 12 forms the roughly L-shaped support lamellar body 13 in cross section, and described support lamellar body 13 is contiguous with guiding groove 120, and is provided with mat base portion 10, support arm 12 around the receiving space 130 that forms.The otch 101 that described base portion 10 protrudes out a projection 131 and is positioned at projection 131 inboards and communicates with receiving space 130 to receiving space 130, described support arm 12 inboards are provided with some embeded slots 122, in addition in support arm lamellar body 13 be formed with the chute 132 that runs through wherein, with at interval holding hole 133 of chute 132 1 ends, fixing boss 135 and the limiting section 134 relative with support arm 12.

See also Fig. 2 and shown in Figure 3, shield shell 2 is for having L shaped two metal sheets body structure respectively, first housing 20 and second housing 21 that connects with it, described first housing 20 and second housing 21 connect the receiving space 25 of accommodating rectangle and L shaped electronic cards with formation up and down.Certainly in another preferred embodiment, second housing 21 need not be set, directly form receiving space 25 and accommodate electronic cards by first housing 20.

Described first housing 20 is roughly L-shaped, comprises L-shaped base portion 22 and the alar part 23 that bends respectively from the base portion left and right sides downwards.Be formed with the lug 230 of some each intervals on the described alar part 23, described lug 230 forms the guiding groove (not label) that inserts in order to the guiding electronic cards.In addition, then be provided with and on base portion 22, be provided with the shell fragment 220 that extends into receiving space 25 for the location division 231 that is positioned on the preinstalled circuit plate, when the rectangle electronic cards is inserted, can prevent that it from rolling in two alar parts, 23 outsides.

The roughly L-shaped body structure of described second housing 21 is provided with the fixing lamellar body (not label) that connects mutually with first housing in its left and right sides.

Moreover, see also Fig. 2 to shown in Figure 6, further organize on the receiving space 130 of this insulating base frame 1 to be provided with and push the trip mechanism 5 that is cycle slip action for rectangle and L shaped electronic cards secondary.This trip mechanism 5 has a pedestal 50, reaches and pushing part 51 parallel and holding parts 52 at interval with pedestal 50 pushing part 51 vertical and the subcards pushing and pressing of can powering in pedestal 50 inboard formation one, is formed with slipping part 53 in pedestal 50 outsides.Be formed with circulation guide groove 530 in the described slipping part 53 for guide rod 54 slippages and location, and corresponding with chute 132 and can be in chute 132 reciprocating fins 532.In the present embodiment, slipping part 53 forms a cascaded surface 533 with pedestal 50, and pushing part 51 vertical directions are long than holding parts 52, and in other words, electronic cards can push against pushing part 51 and drive trip mechanism 5 motions in insertion.

When trip mechanism 5 connects with insulating base frame 1, pedestal 50 and slipping part 53 are housed in the receiving space 130, cooperating of cascaded surface 533 and limiting section 134 wherein, the pedestal 50 of trip mechanism 5 and slipping part 53 are limited in make shuttling movement in the receiving space 130 to avoid skew.Guide rod 54 1 ends are installed in the holding hole 133, and the other end is slippage and location in circulation guide groove 530.Between the projection 131 of slipping part 53 1 ends and insulating base frame 1, be provided with an elastic parts 56, so that the restoring force of trip mechanism 5 to be provided.

It is relative with otch 101 front and back that described pushing part 51 and holding parts 52 exceed limiting section 134, and described pushing part 51 can be contained in the otch 101.When electronic cards is inserted, its front end pushing and pressing pushing part 51, driving trip mechanism 5 moves in receiving space 130, guide rod 54 is also located from the initial position slippage in circulation guide groove 530, after electronic cards is inserted fully, guide rod 54 is limited at the position, a location of circulation guide groove 530, when need move back card, push electronic cards once more, make electronic cards pushing and pressing pushing part 51, guide rod 54 breaks away from the position location of circulation guide grooves 530 and the strain slippage of mat elastic parts 56 navigates to initial position, and trip mechanism 5 also drove electronic cards and broke away from hyoplastron 11 this moment.

For avoiding trip mechanism 5 to break away from the motion of insulating base frame 1 and restriction guide rod 54, further organize on the insulating base frame 1 and be provided with fixing lamellar body 6.Described fixing lamellar body 6 structures and support lamellar body 13 broadly similars, comprise the main part 60 corresponding, be arranged at its edge and in order to cooperating fixing tabling piece 61, and be arranged on another edge and block button hole 62 in order to cooperate with fixing boss 135 on the insulating base frame 1 with embeded slot 122 on the insulating base frame 1 with receiving space 130.In addition, be provided with on the main part 60 of fixing lamellar body 6 to its inner elastic piece structure 63 that extends, this elastic piece structure 63 is contiguous with guide rod 54, prevents that guide rod 54 from coming off in holding hole 133 and circulation guide groove 530 in motion process.

In order to realize the stable fixing of electronic cards and electronic card coupler 100, one metal clips 59 that roughly is v shape structure is installed on the holding parts 52 of trip mechanism 5, described metal clips 59 is between holding parts 52 and pushing part 51, after electronic cards is inserted, this v shape metal clips supports electronic cards, and the fixing that can realize electronic cards and electronic card coupler 100 is to avoid electronic cards and get loose or to rock.Described metal clips 59 can adopt assembling or integrally moulded mode to cooperate with holding parts 52.Certainly, in another embodiment, described metal clips 59 also can be arranged on the pushing part 51 and holding parts 52 can be provided with, after electronic cards is inserted, and metal clips 59 fixings on the mat pushing part 51.Certainly, what noted this moment is, this metal clips 59 keeps at a certain distance away with hyoplastron 11, the pushing part 51 and drive trip mechanism 5 motions so that electronic cards can be conflicted.

In addition, move back the card function, also can another trip mechanism 9 be set in shield shell 20 long sides for the ease of better realization, move back card with trip mechanism 5 collaborative realizations, its detailed structure and operation principle have been known by industry to be known, and irrelevant with the feature of the utility model, so be not described further at this.
