FOREWORD NOTICE: Some test procedures are potentially dangerous. SAE Technical Reports do not purport to address all of the safety problems, if any,
6、 associated with their use. It is the responsibility of the user of an SAE Technical Report to establish and employ appropriate safety practices. Tests should only be conducted by individuals who have been properly trained in the test procedure and who are aware of any hazards which might be present
7、. Appropriate safety and health precautions must be employed when conducting any test. 1. SCOPE This SAE Standard encompasses connectors between two cables or between a cable and an electrical component and focuses on the connectors external to the electrical component. This document provides enviro
8、nmental test requirements and acceptance criteria for the application of connectors for direct current electrical systems of 50 V or less in the majority of heavy-duty applications typically used in off-highway machinery. Severe applications can require higher test levels, or field-testing on the in
9、tended application. 2. REFERENCES 2.1 Applicable Documents The following publications form a part of this specification to the extent specified herein.

17、ECTOR A coupling device, which provides an electrical junction, a mechanical junction, or both, between two cables or between one or more cables and an electrical component. Connectors can also provide for mechanical stability and geometric arrangement. 3.2 TERMINAL An electrically conductive device
18、 attached to a cable to facilitate connection to an electrical component, cable, or termination. 3.3 SEALED A system that creates a nonleaking union between mechanical elements when submerged in a water solution as defined in the tests within this document. 3.4 SIGNAL LEVEL CIRCUIT A circuit in whic
19、h open circuit voltage is typically less than 5 V and current is typically less than 0.05 A. Circuits of this energy level typically are not able to break through oxides, sulfides, or other contaminants, which can build up on the contact surfaces and prevent continuity. 3.5 POWER CIRCUIT A system us
20、ing two or more cables where current flows from the source to one or more electronic/electrical devices and back again to the source. The electrical energy is supplied at high levels of current and typical system voltage (system battery voltage). 3.6 CABLE Insulated stranded electrical conductor use
21、d to establish a single current path. 3.7 WIRING Collectively, the cables, harnesses, connectors, terminations, and supporting components used in the electrical wiring distribution system. 4. SAMPLE PREPARATION Samples shall be made on the connector manufacturers recommended tooling and checked for
22、conformance to the connector manufacturers standards. 4.1 Assembly All connector cavities shall be wired with manufacturers minimum approved cable outside diameter size except for test groups A and D which shall be be wired with manufacturers maximum approved conductor size in lengths sufficient to
23、accommodate testing. Cable diameter shall be checked and be within the connectors manufacturing specification. Crimp characteristics (i.e., height, width, etc.) shall be checked. To prevent capillary action on sealed connectors, all loose wire ends and test points (i.e., millivolt test connection) s

It is permissible to use separate sample sets for Low Voltage Resistance and Insulation Resistance when both are required in the same test sequence. For those sequences requiring both Low Voltage Resistance and Insulation Resistance, tw
26、o groups of 6 may be tested, one group going through the test sequence including Insulation Resistance without Low Voltage Resistance, and the second group going through the test sequence including Low Voltage Resistance without Insulation Resistance. Group A emphasizes mechanical, fluid, and therma

42、 the conductor. The effect of this temperature rise is additive to the ambient temperature conditions. The system working temperature shall not exceed the maximum applicable temperature rating of any component in the current carrying system. Consult the connector manufacturer for these material ther

NOTE: Design application currents should be obtained from SAE J1614. 6.5 Pressure Washing Test Method (Reference SAE J1455) - The mated and cabled connectors under test shall be mounted in its normal operating position with drain holes, if used, open. The test apparatus should be de
44、signed to provide 100% coverage of the exposed surface of the mated and cabled connectors using flat fan spray nozzles located 20 cm to 30 cm (7.9 in to 11.8 in) away. This apparatus should provide a source pressure of approximately 7000 kPa gage (1020 lbf/in2gage) with a flow rate of approximately
45、9460 cm3/min (150 gal/h). The test item should be exposed to the spray for 3 s of a 6 s period for a total of 375 cycles. The test should be run at 40 C (104 F) with water/detergent. An Insulation Resistance test (see 6.3) shall be conducted after this test. A sample test device is illustrated in Fi
