Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The present invention arranges tooth header reading device on proving installation, when plug-in unit is tested, plug-in unit inserts proving installation, tooth header reading device reads the identification characteristics information of anti-plug side set head on this plug-in unit, send to PC, PC, according to identification characteristics information setting test environment, drives proving installation to test plug-in unit.Because identification characteristics information and plug-in unit are unique corresponding, like this, according to identification characteristics information, automatically set test environment and relatively manually set, can effectively improve accuracy rate and the efficiency of plug-in unit identification.
Referring to Fig. 2, the plug-in unit identification system of universal test interface of the present invention is shown, comprise plug-in unit 1 and proving installation 3, plug-in unit 1 has rectangular insert 2, and rectangular insert 2 is provided with anti-plug side set head 8; Proving installation 3 has rectangular receptacle 4 and tooth header reading device 7; PC 6 is connected with proving installation 3 by test cable 5.
During probe card 1, plug-in unit 1 is inserted to proving installation 3, wherein, rectangular insert 2 inserts rectangular receptacle 4, makes plug-in unit 1 and proving installation 3 carry out information interaction; Anti-plug side set head 8 contacts with tooth header reading device 7, and tooth header reading device 7 reads the identification characteristics information of anti-plug side set head 8, sends to proving installation 3, and shows.Proving installation 3 sends to PC 6 by identification characteristics information, and PC 6 loads corresponding test procedure automatically according to identification characteristics information, builds test environment, drives proving installation 3 to detect plug-in unit 1.
Referring to Fig. 3, tooth header reading device of the present invention 7 structural drawing are shown.Tooth header reading device 7 comprises the shake-up display of 12 groups of parallel connections, and it is identical that each group is touched display device structure.Take first group of shake-up display as example, touch display and comprise microswitch K1 and light emitting diode D1, the anodic bonding of the fixed contact of microswitch K1 and light emitting diode D1, and connect signal output part D01; The second moving contact (2) is connected and ground connection with the negative electrode of light emitting diode D1 by resistance R 1, and the first moving contact (1) is connected with positive source.
When microswitch K1 is during in the second moving contact (2) position (default conditions), whole circuit is off state, digital quantity signal output terminal D01 is equivalent to directly be connected with ground, therefore light emitting diode D1 is low level, be output as 0 signal, light emitting diode D1 is because of positive ending grounding simultaneously, and no current flows through, and is non-luminous state.
When plug-in unit 1 inserts proving installation 3, anti-plug side set head 8 contacts with tooth header reading device 7, microswitch K1 is touched, make microswitch K1 when the first moving contact (1) position, form closed-loop path, digital quantity signal output terminal D01 is equivalent to be directly connected with+5V, now light emitting diode D1 high level, light emitting diode D1, because have electric current process in loop, is luminance.
Anti-plug side set head 8 has multiple location points, each location point is corresponding one by one with each microswitch of tooth header reading device 7, and as this location point has tooth, tooth can touch microswitch, make the digital quantity signal output terminal output high level that this microswitch is corresponding, lumination of light emitting diode; As this location point does not have tooth, just can not touch microswitch, the digital quantity signal output terminal output low level that this microswitch is corresponding, light emitting diode is not luminous.
In conjunction with Fig. 2 and Fig. 3, specific works process is as follows.
When plug-in unit 1 is not connected with proving installation 3,2 positions of microswitch K1-K12 in acquiescence, circuit is off-state, the equal output low level of digital quantity signal output terminal D01-D012;
After plug-in unit 1 is connected with proving installation 3, on plug-in unit 48 core rectangular inserts, anti-plug side set head 8 can be pressed corresponding microswitch K1-K12, corresponding microswitch K1-K12 is placed in to 1 position, partial circuit forms closed-loop path, therefore corresponding digital output end can be exported high level, and corresponding light emitting diode also can be lighted simultaneously.
No. 12 microswitches disconnect or closed information, can represent in theory the combination of 2^12=4096 kind low and high level, can distinguish the information of 4096 kinds of different electronic housing plug-in units, much larger than the quantity of current package types.The digital output signal on proving installation Dui12 road detects, and testing result is transferred to PC 6 by test cable line 5, PC 6 completely can be according to the various plug-in units 1 of not homotactic low and high level signal distinguishing, automatically load corresponding test procedure, build test environment, plug-in unit 1 is detected.
After test finishes, plug-in unit 1 is separation with proving installation 3, and the microswitch in proving installation 3 also returns to initial state, and whole circuit also recovers initial off-state.
The foregoing is only the preferred embodiment of the present invention, do not form limiting the scope of the present invention.Any any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present invention.
