Description

Electronic card coupler

The utility model relates to a kind of electronic card coupler, refer in particular to a kind of its earthing device can be directly and the ground path of circuit board constitute electrical contacting electronic card connector.

The prior art relevant with the utility model sees also the TaiWan, China patent application No. 85216014, as shown in Figure 1, existing electronic card coupler 10 is electrically connected on the first circuit board 12, wherein electronic card coupler 10 comprises insulating base frame 14, this insulating base frame 14 is provided with terminal accommodating district 16, and plurality of conductive terminals 18 is located at wherein.These conducting terminals 18 have welding ends 20, this welding ends 20 is done the design that raises with respect to first circuit board 12, promptly this welding ends 12 is towards doing suitable bending away from the direction of first circuit board 12, welding ends 20 is connected on the second circuit board 22 with perforation means then, and this second circuit board 22 is plugged on the switching electric connector 24 on the first circuit board 12.The earthing device (not shown) that is positioned at insulating base frame 14 close first circuit board one sides is provided with some earth terminals 26, these earth terminals 26 and conducting terminal 18 are done to bore a hole after the same bending and are connected on the second circuit board 22, by the electrical switching of switching electric connector 24, earthing device (not shown) and the corresponding line on the first circuit board 12 on the electronic card coupler 10 are electrically connected then.

Yet, because earth terminal 26 all is connected on the second circuit board 22 with the welding ends 20 of conducting terminal 18, cause the bending design of earth terminal 26 to make that welding ends 20 is forced to also do bigger bending to same direction, the certain height and the welding ends 20 that makes conducting terminal 18 accounts for, thus the loss of computer inner space caused.As shown in Figure 1, the welding ends of conducting terminal 18 20 and earth terminal 26 insert behind the second circuit boards 22 must through welding process with second circuit board 22 on electrically connect, this operation will expend processing costs such as more manpower, equipment inevitably.The earth terminal of earthing device palpus process second circuit board and switching electric connector connecting on the earthed circuit that can be electrically connected to first circuit board in addition, the obviously oversize and electric contact region by many different components therebetween of this ground connection approach distance, its contact impedance is obviously excessive, is unfavorable for the rapid eliminating of electrostatic charge on the earthing device.

The purpose of this utility model is, a kind of electronic card coupler is provided, this electronic card coupler can be directly and the earthed circuit of circuit board connect and effectively improve ground connection usefulness.

The purpose of this utility model is to realize like this, electronic card coupler comprises insulating base frame and some conducting terminals that is contained in the insulating base frame, near circuit board one side one ground strip is set at insulating base frame simultaneously, ground strip is provided with the flexible earth terminal of tool, at electronic card coupler with after adaptor connector on the circuit board is connected, the earth terminal of ground strip can be directly with circuit board on corresponding connection pad contact and realize electrically connecting.

Owing to adopted above scheme, the utlity model has following advantage, can before and after pegging graft, electronic cards get rid of electrostatic charge on it or noise rapidly to guarantee the stability and the reliability of the transmission of electronics cassette group mould electronics.And therefore the arrangement that need not consider earthing device can effectively reduce electronic cards and connect whole height, and then saves the inner space of electronic installation
