Description
Technical field
The present invention's design relates to a kind of technology of sliding and electrically contacting of simulating, and specially refers to a kind of slip and electrically contacts simulated testing system.
Background technology
In communication, computing machine, measurement, control and all kinds of electronic system, need a large amount of electronics to connect.They play between the various electronic component circuit, between the equipment and even the effect of maintaining each other between the system.Electrically contacting is to specialize in the science that electronics connects, and is to be used for describing a kind of state that two assemblies produce because of charged contact.Electronics connects to be realized through physical construction mostly.In real life; The for example plug of the plug of earphone, power connection, latch are relatively and the plug of socket or the like; The capital produces significantly motion, and the relevant sizable motion of relative motion amplitude that switches on and off between electronic devices and components is called as slip.Friction and wear is the important phenomenon of sliding and to electrically contact, and friction will make the energy loss in the sliding process, wearing and tearing then make surface metal particularly noble metal lose rapidly, expose base metal, thereby cause corrosion and loose contact.
For the better influence of research sliding phenomenon to electrically contacting, reduce sliding friction and the loss that wearing and tearing cause electrical equipment, improve the reliability of electrical equipment.Assessment, function life-span to this index of electric connector are predicted so that in the malfunction analysis procedure, laboratory simulation is present internationally recognized effective means.Contact Resistance is as an important indicator that weigh to slide lost efficacy, and dynamically reproduced the variation of contact resistance in the sliding process and to the electrical contact performance effect, is to analyze and key parameter that research is slided.
Electrically contacting the field, particularly using low voltage connector for communication, the contact pressure of employing is less; But wider range that contact pressure changes; To gram forces up to a hundred, the amplitude of slip does not also wait from several millimeters to tens millimeters from several gram forces, and the cycle of slip, generally all this was longer.Thereby in research and analysis, the method that often adopts the laboratory to quicken simulation is quickened the process that connector slides, and simulation is slided and lost efficacy.
The Contact Resistance test macro is the experimental provision that quickens simulation connector sliding phenomenon; Generally electrically contact right relative motion through the control linkage device; Quicken the process that the simulation connector slides; Right contact resistance value and the automatic record of contact in the test sliding process, test is slided to the influence of electrical contact performance.
Fig. 1 is existing Contact Resistance test system structure synoptic diagram.As shown in Figure 1, comprise Contact Resistance test cell 11, sliding stand module 12, computer unit 13 and pedestal 14.Wherein,
Contact Resistance test cell 11 comprises constant current source 111, normal pressure bringing device 112, test contact 113, test sample 114, reaches digital multimeter 115.
Constant current source 111 first ends link to each other with test contact 113, and second end links to each other with test sample 114; Being set at test contact 113 offsides that digital multimeter 115 first ends of dc voltage measurement shelves link to each other with constant current source 111 links to each other; Test sample 114 offsides that second end links to each other with constant current source 111 link to each other, the CC that connects and composes four-point method between constant current source 111, test contact 113, test sample 114 and the digital multimeter 115;
Test sample 114 is fixed on print fixed station 121 surfaces, and test contact 113 contacts with test sample 114 and forms test access in the test;
Be set at the digital multimeter 115 of dc voltage measurement shelves, link to each other with computer unit 13, send data to computer unit 13 through 232 serial ports;
Test sample 114 is fixed on fixed station 121 surfaces on the slide block of ball screw assembly, 122, and the leading screw of ball screw assembly, 122 is connected with stepper motor 123, can rotatablely moving of stepper motor 123 be converted to the rectilinear motion of fixed station 121.Computer unit 13 sends to motor driver 124 with signal; Through the frequency of the pulse signal that sends and the rotating speed and the stop position of quantity control step motor 123, promptly may command test sample 114 is with respect to the point-to-point speed and the stop position of test contact 113.Through changing the counterweight weight that is applied on the normal pressure bringing device 112, then can the contact pressure of regulating action between test contact 113 and test sample 114, can carry out the Contact Resistance test under the different contact pressures;
Pedestal 14 is used for the physical construction of support system, the isolation environment vibration, impacts the influence to the Contact Resistance test
But there is following problem in the existing glide Contact Resistance Test System:
1, less stable in the Contact Resistance test process.Under sliding condition,, certain roughness is arranged all because contact and print surface are not absolute level and smooth; So when contact slides with respect to print; Contact can produce jump phenomena because of the instantaneous impact that makes progress, and this normal pressure bringing device does not suppress the upwards structure of spring of contact, causes the size of normal pressure to suddenly change; And contact causes the circuit between contact and the print to open circuit when upwards bouncing, and causes the experimental data sudden change.
2, the accurate location that can't on the experiment print, carry out slipway location is chosen.The installation of print on objective table do not have locating device, and dismounting can't make follow-up slip be positioned on original slideway after installing again, limited the experiment of slip repeatedly at experiment print same position.
3, can't be at the different eroded areas foundation of slideway and the direct relation of swept resistance.Resistance measurement in the sliding process is identical time interval sampling, is variable motion and slide, and each resistance value can't be corresponding with the contact position in the slideway.
4, can't measure the temperature value of contact interface.The existing glide Contact Resistance Test System does not have temperature measuring equipment.
5, TCH test channel is less.The existing glide Contact Resistance Test System has only 1 passage, can only be to a groups of contact to quickening the sliding die draft experiment, and conventional efficient is very low.
