What is the standard for crimping wire harness terminals? What are the evaluation criteria?

The crimping standard for wire harness terminals refers to the specifications and requirements for correctly crimping wire harness terminals to ensure stable and reliable electrical connections. The following is an overview of general wire harness terminal crimping standards and evaluation criteria:
Crimping standard:
Crimping pressure: It is required to have an appropriate crimping pressure, which should not be too low to cause poor electrical contact, nor too high to cause deformation or damage to the wiring harness terminals.
Crimp length: The correct crimping length is required to ensure that the wire harness is fully inserted into the terminal slot and in close contact with the conductor.
Crimp position: It is required to place the wire harness correctly in the terminal slot to ensure good electrical contact and reliable connection.
Crimping tool: It is required to use appropriate crimping tools, such as crimping pliers or crimping machines, to ensure crimping strength and consistency.
Evaluation criteria:
Electrical connection reliability: Evaluate whether the crimped wire harness terminals can provide stable electrical connections through resistance testing or electrical performance testing.
Physical connection quality: Check the physical connection between the crimped harness terminals and wires, including whether the contact between the pins and wires is firm.
Appearance quality: Evaluate the appearance of the crimped wire harness terminals and check for any obvious exposed wire harness, damaged or deformed wire harness terminals, etc.
In addition, there may be specific crimping standards and evaluation criteria for different types of wire harness terminals. These standards are typically developed by manufacturers or industry organizations and may vary depending on the materials used, electrical requirements, and application areas. Therefore, in specific applications, it is recommended to refer to relevant manufacturer documents, technical specifications, or industry standards to ensure correct crimping and evaluation.
