The Strain Relief Device Of The Heavy-duty Connector Is Matched With The Material Of Its Terminals.

Strain Relief Devices: Strain relief devices or back covers for 12v heavy duty connector applications can be a primary standard for the additional safety provided by non-conductive strain-relief housings. If terminals or wires are dislodged from their fixed positions within the heavy duty crimp connectors housing due to mechanical overload, stress relief devices prevent “live” wires from contacting other parts or “neutral” conductive components in heavy duty waterproof electrical connectors applications.

heavy duty connector Housing and Terminal Materials and Terminal Plating: Materials and plating are often one of the final major decisions. Most heavy duty electrical connectors terminals are made of nylon plastic. The flammability rating of nylon is typically 94V-0, equivalent to UL 94V-2. A higher 94V-0 rating indicates that the nylon extinguishes fire faster (in case of ignition) than 94V-2 nylon. A 94V-0 rating does not imply a higher operating temperature rating for heavy duty power connectors applications, but it does indicate higher flame retardancy. For most heavy duty connector 24 pin applications, 94V-2 material is sufficient.
