11、B.) 1 Introduction 1.1 Scope This procedure is to define a method of detecting a discontinuity of one microsecond or longer in a mated electrical connector, contact or socket. This procedure shall not be used for durations less than one microsecond; see EIA-364-87, Test Procedure for Nanosecond Even

12、t Detection. 1.2 Definition A discontinuity is defined as a series loop resistance of 10 ohms or greater lasting for one microsecond or longer, measured at the detector input unless otherwise specified in the referencing document. 2 Test Resources 2.1 Equipment The test equipment shall consist of a

13、detector and a power supply (internal or external to the detector) and associated wiring. 2.1.1 Detector A detector shall be used that will register when a resistance is detected, indicating that a discontinuity , see 1.2, has occurred. 2.1.2 Power supply The power supply may be separate from the de

14、tector. The power supply shall be capable of supplying 100 milliamperes dc. The power supply shall be capable of supplying open circuit voltage not to exceed 5.0 volts. Power supply regulation response time shall be 0.1 microseconds or better. EIA-364-46C Page 2 3 Test specimen 3.1 Description The t

15、est specimens shall consist of fully terminated connectors. 4 Test procedure 4.1 Contacts shall be wired in one or more series circuit(s) with each circuit connected to a separate detector channel, or shall be individually connected to a separate detector channel (one detector channel for each conta

16、ct). The maximum initial resistance of any individual series loop circuit shall not exceed 3 ohms. If the resistance exceeds 3 ohms, additional circuits shall be required and connected to additional detectors. 4.2 False failure may be caused by electrical noise or interference. If a discontinuity is

17、 indicated, the detector shall be reset. If any further discontinuities occur, the time and test parameters resulting in said discontinuity shall be recorded and reported. Specimens shall not be failed by a single discontinuity indication when the detector is reset and the discontinuity does not rec
