What is the Discrete Wire Termination spec of RJ type connector?
RJ type connector is wildly used in consumer, communication industry. How to ensure the wire termination properly? Please refer to IPC standards.
Target - Class 1,2,3
• All wires are bottomed in connector and visible through the front of the connector.
• The primary strain relief is crimped tightly against the cable jacket.
• The cable jacket extends past the point of the strain relief.
• For connector without a loading bar, the secondary strain relief is crimped so that it is in contact with the insulation.
• The contacts are crimped so that no part of the contacts are above the plane created by the top of the plastic dividers between the contacts.
Acceptable - Class 1,2,3
• Wires are not bottomed but all are within 0.5 mm [0.02 in] or less of the end wall but all are inserted at least past the terminal.
• Contacts meet the connector manufacturers crimp height specification.
Defect - Class 1,2,3
• The primary strain relief is not in tight contact against the cable jacket or is not latched.
• The cable jacket does not extend past the primary strain relief.
• Wire ends are not within 0.5 mm [0.02 in] or less of the contact end wall. or are not inserted past the terminal.
• All wire ends are not visible through the face of the connector.
• Connector without loading bar the secondary strain relief is not in contact with the wires or is not latched.
• The contacts are not crimped sufficiently and extend above the plane created by the top of the plastic dividers between the contacts
