Description

Electronic card coupler

The utility model relates to a kind of electronic card coupler, is meant that especially a kind of employing thin type winding mode and circuit board are connected with group with the reduction whole height, and can firmly be combined on the circuit board so that the good electronic card coupler that electrically engages effect to be provided.

Electronic card coupler is used for winding at circuit board, goes into and itself and circuit board are electrically connected for the electronic cards group, effectively provides specific function to be beneficial to different electronic installations such as notebook computer group admittedly thereon whereby.With regard to regard at present common electronic card coupler design, these electronic card coupler great majority are directly to be arranged at appropriate location on the circuit board face, reach the transmission of telecommunication so that the terminal in a row that is convexly equipped with on the one end is engaged in respectively on the circuit board.Yet, the space that this design obviously additionally will be accommodated electronic cards also is arranged on the circuit board, many available spaces on the circuit board plate face have been taken, and electronic cards and electronic card coupler all have the height (or thickness) of certain degree, whole winding height can't be reduced, make electronic installation especially notebook computer be difficult for thin typeization.At present, existing design is set directly at circuit board plate edge with electronic card coupler, is beneficial to the slimming design to reduce whole height.But the numbers of terminals of electronic card coupler is numerous, must be located and align by instrument in the time of on being welded in circuit board, makes terminal engage poor effect to avoid engaging process to rock improperly.For overcoming the problems referred to above, common settling mode is the front end side screw that protrudes out joint at the electronic card coupler terminal, is locked so that this front is mounted on circuit board and by bolt.Yet bolt locking mode is quite wasted built-up time, and electronic card coupler mounted on circuit board also can increase assembled height.

The purpose of this utility model is to provide a kind of and has low clearance winding mode and in conjunction with firm electronic card coupler.

The purpose of this utility model is achieved in that this electronic card coupler comprises insulating body, its two opposite sides are respectively equipped with interface and composition surface, to be abutted against for butt joint electronic cards and circuit board respectively, in the composition surface of insulating body both end sides to extending meeting device away from the direction one, this meeting device is two cantilevers, which is provided with holding hole and be equipped with a retaining piece, and the side surface that the cantilever extending end relies on circuit board is provided with the butt depression can make the plate side of circuit board be installed in wherein, wherein this cantilever is provided with the height that highly is significantly less than insulating body, like this, with the circuit board butt after greatly reduce whole winding height, thereby saved the inner limited usage space of computer and helped the thin typeization of electronic installation.

Advantage of the present utility model is: the whole height after electronic card coupler and the circuit board winding is lower, and in conjunction with firm.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is that the first figure A-A is to cutaway view.

Fig. 3 is a partial sectional view of the present utility model.

See also Fig. 1, Fig. 2, the utility model comprises insulating body 1, is contained in plurality of conductive terminals 2 and meeting device 3 in this insulating body 1, wherein this insulating body 1 is provided with interface and composition surface, for butt joint electronic cards (not shown) and be abutted against mutually, be provided with the plurality of terminals accepting groove 11 that runs through two sides conducting terminal 2 with respectively between this interface and the composition surface with ccontaining corresponding number with circuit board 4.Electrically conduct with electronic cards with the interface that extends to insulating body and an end of conducting terminal 2 is made as docking section 21 (seeing also Fig. 2), its other end then is made as junction surface 22 electrically to be engaged on the circuit board 4.Meeting device 3 is that the two ends, composition surface of insulating body 1 are along extended two cantilevers 31 of electronic cards direction of insertion one in the present embodiment, its side surface parallel with electronic cards butt joint direction is made as first surface 311, and another surface relative with first surface 311 is made as second surface 312, and the second surface 312 of this cantilever 31 is provided with the butt depression 313 plate sides with power circuit board 4 and is installed in wherein (seeing also Fig. 3).This cantilever 31 is provided with holding hole 32 and can be retained on retaining piece 33 in the holding hole, wherein holding hole 32 is for being located at the rectangular through holes of adjacent and parallel perforation cantilever 31 on two cantilevers 31, and the 311 suitable indents of the first surface between two holding hole 32 form concave surface 321, so that can not protrude from outside the insulating body 1 after retaining piece 33 assemblings, and the contact position of concave surface 321 and two holding hole 32 all is set as inclined-plane 322, so that the insertion of retaining piece 33.33 of retaining pieces have fixing end 331, binding end 332 and fixing body 333, wherein fixing end 331 and binding end 332 are that fixing body 333 both sides bend towards same direction and form, and fixing end 331 convexes with away from a side of cantilever 31 first surfaces 311 a pair ofly to be diverged " V " shape and has certain flexible fixing pin 3311 mutually, its end has the holding section 3312 of overhead kick shape, this holding section 3312 can be interfered with set in advance hole on the circuit board 4 41 and cantilever 31 effectively is immobilizated on the circuit board 4 together with insulating body 1 integrated with it, thus the moving up and down of restriction insulating body 1.And the binding end 332 of retaining piece 33 is relatively short end, and its two lateral border has the interference part, this interference part be four square protruding 3321, it can be interfered with the inwall of the through hole 32 of described cantilever 31 and make retaining piece 33 strong fixs in holding hole 32.

See also Fig. 3 again, during assembling, make circuit board 4 be attached to described cantilever 31 second surfaces 312 so that its plate edge is connected to butt on the second surface 312 313 places of caving in, and the hole 41 of the fixing end 331 corresponding circuits plates 4 of retaining piece 33 is inserted in the through hole 32, fixing body 333 is taken just and is put on the concave surface between the two through hole 32 321 at this moment, borrow fixing end 331 to run through circuit board 4 and interfere with hole 41 elasticity on the circuit board 4, and thereby the projection 3321 and 32 inwalls that pass through binding end 332 are interfered insulating body 1 strong fix on circuit board 4, therefore effectively reduce the whole height after the assembling, thereby saved limited usage space in the computer.
