Buyer takeaway
Clarify the connector requirement
Compare product and solution paths
Prepare RFQ details before quotation
Define the approved configuration
Freeze the housing, terminal, seal, wire, cable, cavity plug, secondary lock and mating component before testing. A result is meaningful only for the exact configuration, assembly process and sample condition recorded in the test plan.
Electrical and thermal checks
Typical project reviews can include continuity, contact resistance, insulation, dielectric performance and temperature rise under defined current, cable, duty cycle and ambient conditions. Acceptance limits must come from the customer or controlled project specification.
Mechanical and assembly checks
Review mating and unmating force, terminal retention, connector lock engagement, polarization, CPA or secondary-lock operation, crimp condition and harness strain. Include checks before and after environmental exposure when required.
Environmental and sealing checks
Select temperature cycling, vibration, mechanical shock, water, dust, humidity, salt or fluid exposure according to the vehicle location. Record test method, severity, sample count, sequence and pass/fail criteria rather than using an IP label as the complete plan.
Close the evidence package
Link the plan to sample identifiers, drawings, equipment, raw data, photographs, deviations and approvals. Any material, tooling, terminal, seal or process change should trigger a documented review of affected validation evidence.
FAQ
Common questions
Common procurement and engineering questions related to this topic.
Is one standard test list suitable for every automotive connector?
No. Tests, severity, sequence and acceptance criteria depend on the application, vehicle location, electrical load, interface and customer specification.
Should the connector be tested without the wire and seal?
Component tests can be useful, but assembly validation should use the approved terminal, wire, seal, mating part and process because they affect real performance.
