Inspection standards for automotive connectors

Following the continuous improvement of automobile performance, as an important part of the automobile connector is also put forward higher requirements. Host factory in the use of an automotive connector before, through the corresponding test specifications to check the quality of the connector. So what kind of requirements do the major OEMs have for the inspection specifications of automotive connectors and wiring harnesses?

The automotive connector test specification mimics the visible stresses on a crimped connector over its typical life cycle and ensures that the crimp is mechanically robust and the current is stable. The specification was developed primarily for use with a single automated copper wire. Only those other constructions or other central materials specifically mentioned somewhere are applicable. This specification does not apply to unspecified wires. This specification is based primarily on the ambient exposure levels acceptable for automotive equipment. In any pre-established automotive facility, it is assumed that if a product is accompanied by this specification, it will be necessary for that product to comply with the conditions depicted in this document. Before they can be recognized as practically usable automotive equipment, they must pass a special test that mimics the conditions in practice. Suppliers who have been certified as having passed the specific applicable part of this specification will not be required to carry out this test, as their products have already passed the test to a high degree of satisfaction. Any faults must be documented in the test report. Crimping equipment complying with this specification will take the crimping information from the part printing paper. Terminal suppliers on this test and crimp the selection of things have the basic responsibility, but also has the responsibility to provide specific crimping information, so that the wire assembly suppliers know specifically crimp things information to better in the practice of the production process to do a good job in the product crimping. Harness suppliers have the responsibility to recognize all crimps produced by each specification. Environmental exposure activities in the specification include thermal shock, temperature and humidity cycling, which are also used to apply pressure to the product terminals and cable bonding in the test environment to mimic field exposure.LV214-2010 will examine the crimp geometry of the mold, plating quality, wire and cable distribution of these shortcomings. In addition to having a connector system recognized as LV214-2010 to ensure that the overall product crimp height plan is acceptable, it is necessary to implement LV214-2010. test a connector system specification to also recognize those not detected by the LV214-2010, such as high-temperature exposure. The procedures included in the specification are programmed to include performance testing and opening of electric terminal crimping, which is only one component of an electric connector in a low voltage (0-48VDC), road vehicle using an electronic connection system with a maximum temperature of 125. Higher voltage and temperature testing will be necessary, assuming that the OEM customer agrees to these procedures for voltages and temperatures beyond this limit.

LV214-2010 test items include not bound: scale characteristics material characteristics classification class test end plates and directly connected parts terminal samples preparation connector and / or terminal cycle visual inspection circuit continuity monitoring terminal mechanical properties test polarization characteristics effects mixed parts engagement / separation force oscillation / mechanical shock terminal to terminal engagement / separation force terminal bending force terminal electrical properties test low power ( weak current) circuit resistance voltage drop maximum test current performance 1008 hours current cycling connector mechanical performance test terminal to connector stabbing/withdrawal force connector to connector cooperation/separation force (connector without mechanical assistance) connector to connector audible tower ring connector drop test mold cavity damage factor terminal/cavity polarization test connector electrical performance test insulation resistance connector environmental test thermal Shock temperature/humidity cycle high temperature exposure fluid resistance immersion pressure/vacuum leakage special test end plate pin adherence connector outboard structure mechanical strength strenuous duty test high pressure eruption violent oscillation
