Description

Electronic card connector

The utility model relates to a kind of electronic card connector, refers in particular to a kind ofly can and make it keep the electronic card connector of location with the electric connector terminal fixing.

Computer technology flourish, not only the accuracy to each assembly of computer structure itself requires more and more higher, and it is also more and more higher to the reliability requirement that connects between each assembly, and for the high density electrical connector terminal, guarantee the reliability that is in contact with one another between terminal, effective transmission of signal is seemed to be even more important.

The electronic card coupler terminal has dual mode usually with the connection of motherboard at present: the first is welded the correspondence position of electronic card coupler terminal and motherboard mutually, it two is that electric connector on electronic card coupler and the motherboard is pegged graft, and the latter be detachable connection mostly so that electronic card coupler is changed easily and keeped in repair.The electronic card coupler that electric connector on existing and the motherboard plugs, its termination contact section generally is housed in the detent mechanism, and relative configurations can be consulted United States Patent (USP) the 5th, 636, and 999,5,688, No. 130 cases.As shown in Figure 1, double-deck electronic card coupler 7 contains two row's terminals 70, and terminal 70 approximately is bent into " L " shape, and its first contact jaw 70 inserts detent mechanisms 8 and is contained in the reception room 82 from two row's terminal mouths 81, and is resisted against two walls of reception room 82 respectively.In addition, when electronic card coupler 7 when electric connector for socket 9 on the motherboard docks, this reception room 82 can be accommodated the joining section 90 of electric connector 9 in it just, and makes the terminal 91 of motherboard electric connector 9 contact and realize electrically conducting with terminal first contact jaw 70 of electronic card coupler 7 respectively.But, existing electronic card coupler terminal is in the detent mechanism wall by himself resilient abutment, lack necessary interference each other, thereby the elasticity of terminal weakens gradually along with the prolongation of service time, can not remain with two walls effectively against, simultaneously there is the gap easily between terminal and wall, under the contact pressure effect between terminal, can moves, thereby cause docking the connector terminals loose contact mutually and influence telecommunication transmission to wall.

The purpose of this utility model provides the reliable fixing electric connector terminal of a kind of energy and makes it keep the location, helps terminal and motherboard electric connector to stablize the contacting electronic card connector.

The purpose of this utility model can realize by following technical scheme: the utility model comprises electronic card coupler and the detent mechanism that engages with electronic card coupler, wherein this electronic card coupler comprises some " L " shape terminal, and be arranged to two-terminal row at least, and detent mechanism comprises a matrix, which is provided with terminal interface and reception room, wherein the terminal plug receptacle is corresponding to the terminal board setting, and terminal interface row and row's wall spacing is greater than two-terminal row's spacing; Reception room then extends setting along the terminal interface away from its Way in, be used to accommodate bonder terminal and motherboard electric connector, pass through said structure, after inserting, terminal can tightly be resisted against two walls of reception room all the time, when guaranteeing that the butt joint electric connector terminal inserts, the electronic card coupler terminal can not produce because of the contact pressure between terminal to the moving of sidewall, thereby keeps two electric connector terminal contact stabilizations.

Compared with prior art, the utility model is different by electric connector terminal row spacing and terminal interface spacing, can reach reliable fixing electric connector terminal and make it keep the location, helps terminal to stablize with the electric connector on the motherboard and contacts.

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