Description

Electric connector

[technical field]

The utility model is about a kind of electric connector, refers in particular to a kind of electric connector that flexible PCB is electrically connected to circuit board.

[background technology]

The electric coupler component that flexible PCB is electrically connected to circuit board comprises pin connector and socket connector, and pin connector connects mutually with flexible PCB, and socket connector is inserted in circuit board.Existing socket connector comprises insulating body, be inserted in signal terminal in the insulating body, be connected to the earth terminal of insulating body and be coated on the shielding casing of insulating body outer surface.Wherein the earth terminal of socket connector not only connects mutually with the earth terminal of pin connector, and must connect mutually with shielding casing.

The United States Patent (USP) 6th of relevant patent as announcing November 13 calendar year 2001,315, No. 616 disclose, the earth terminal of the socket connector of existing electric coupler component needs in signal terminal is inserted in the terminal storage tank that a side of socket connector insulating body offers, and this earth terminal and signal terminal are provided with the terminal storage tank insulation wall interference engagement of protruding thorn and socket connector insulating body by its sidewall and are immobilizated in the terminal storage tank, because it is more that the insulating body of this socket connector is offered the number of terminal storage tank, so two-terminal storage tank spacing is less, institute diminishes every insulation wall attenuation and its intensity, terminal interferes protruding thorn fully not interfere in the insulation wall, thereby cause the fixing degradation of storage tank to terminal, earth terminal and signal terminal easily produce the phenomenon that gets loose in the terminal storage tank, and then and the terminal of pin connector between easily produce and connect unstable defective.

Thereby the earth terminal of this socket connector is to press together by its part and shielding casing to realize being electrically conducted, and this earth terminal also is provided with cantilever-shaped junction and pushes cooperation mutually with the earth terminal of pin connector, and the earth terminal of this socket connector is subjected to the extruding of pin connector earth terminal and pushes the shielding casing of socket connector.At this socket connector after repeatedly pegging graft with pin connector, this socket connector earth terminal be subjected to the extruding of pin connector earth terminal and push the shielding casing of socket connector repeatedly.Because of the shielding casing of this socket connector is a monolayer constructions will, so rigidity is not good,, not only influence the outward appearance of socket connector, and easily generation can't correctly cooperate with butt connector in that to stand to push the back repeatedly yielding, and the defective that conducting terminal can't be electrically conducted.

The earth terminal of this socket connector and shielding casing are two assemblies of independent separate, need develop two molds during manufacturing, and cost is higher, and the product development fabrication cycle is longer.In addition, contacting the position between earth terminal and shielding casing is that the relatively poor interplanar of two elasticity contacts, thus its contact steadiness be difficult for guaranteeing, if extruding force then easily produces breaking phenomena inadequately therebetween.

[utility model content]

The purpose of this utility model is to provide a kind of and docks well, connects stable electric connector.

The purpose of this utility model is achieved in that this electric connector comprises the shielding casing of insulating body, coated insulation body and is placed in the interior signal terminal of insulating body.Shielding casing is provided with two retaining walls that are parallel to each other, wherein a retaining wall is provided with and spaced apart several windows that is provided with for double-deck, extend in one of window sidewall and to be provided with cantilever-shaped earth terminal, extend in this retaining wall and be provided with several and connect pin, this connects pin and is inserted in circuit board and electrically conducts with circuit board.Insulating body offers several storage tanks, and shielding casing extends and to be provided with several pins being inserted in this storage tank, and the setting of staggering mutually of the pin of shielding casing and window.

Compared with prior art, the utlity model has following advantage: the shielding casing and the earth terminal of this electric connector are formed in one, therefore can avoid insulating body to influence its fixing performance, thereby guarantee that insulating body is firm to the signal terminal fixing because of offering the ccontaining earth terminal of terminal storage tank in addition.The shielding casing part of this electric connector is provided with for bilayer so rigidity is better, not yielding.

[embodiment]

See also Fig. 1 and Fig. 2, the utility model electric connector 1 can be electrically connected at that circuit board (not shown) is gone up and match with another flexible circuit board connector (not shown) and flexible PCB is electrically connected to circuit board, and it comprises insulating body 2, shielding casing 3 and is placed in signal terminal 4 in the insulating body 2.Insulating body 2 comprises base portion 21 and auxiliary section 22, wherein base portion 21 longitudinallies are formed with mating surface 211, auxiliary section 22 is vertically to extend from one of base portion 21 longitudinallies side, base portion 21 and auxiliary section 22 relative opposite sides keep at a certain distance away and offer several accepting grooves 212, and the arragement direction of these several accepting grooves 212 is parallel with auxiliary section 22 bearing of trends.22 sidewall spacers towards accepting groove 212 offer several storage tanks 221 in the auxiliary section, and this storage tank 221 is to extend and one runs through base portion 21 along the direction vertical with mating surface 211 away from an end of mating surface 211 from this sidewall.

Signal terminal 4 is inserted in the storage tank 221 of insulating body 2, and it comprises holding parts 41 and the contact site 42 and afterbody 43 that extend from holding parts 41 opposite ends.Holding parts 41 can be immobilizated in signal terminal 4 in the storage tank 221 with the madial wall interference engagement of storage tank 221, and afterbody 43 is inserted in circuit board to be electrically conducted with circuit board, and contact site 42 can be electrically conducted with the signal terminal (not shown) of butt connector.

Shielding casing 3 is coated on the outer surface of insulating body 2, it is provided with two retaining walls that are parallel to each other: first retaining wall 31 and second retaining wall 32, wherein second retaining wall 32 can be connected to the mating surface 211 of insulating body 2, second retaining wall 32 is that bearing surface 321, the second retaining walls 32 are bottom surface 322 with the surface that circuit board connects with the surface that mating surface 211 connects.Bearing surface 321 is extended with pin 323 to be inserted in the accepting groove 212 and shielding casing 3 is connected to insulating body 2 in the relevant position of the accepting groove 212 of insulating body 2 to insulating body 2 directions.Bottom surface 322 is extended two in the position of contiguous bearing surface 321 to the circuit board direction and is connected pin 327, and this connects pin 327 and is inserted in circuit board and electrically conducts with circuit board, thereby with signal ground.Second retaining wall 32 extends a segment distance away from a side direction bearing surface 321 directions bending of bearing surface 321, second retaining wall 32 is provided with, to increase by second retaining wall 32 in the rigidity of longitudinally for double-deck in this part.

Second retaining wall 32 offers several square window 324 along accepting groove 212 positions of the corresponding insulating body 2 of its longitudinally, and the setting of staggering mutually of this window 324 and pin 323.Sidewall in window 324 close bearing surfaces 321 is extended with cantilever-shaped earth terminal 325 to the direction one away from bearing surface 321, these earth terminal 325 integral body are extended to first retaining wall 31 inclinations, one angle, and its free terminal convexes with junction 326 to match with the earth terminal (not shown) of another butt connector to first retaining wall, 31 directions.
