Secure Ring Terminal Connections for Electrical Installations

Ring terminals provide a dependable method of connecting electrical conductors to screw and stud terminals. The Partex UBR37 features a closed-ring connection designed to fit a compatible M3.5 fixing. Unlike open-ended terminal designs, a ring terminal remains captured around the fixing until the screw or nut is removed, helping provide additional connection security in equipment exposed to routine handling or vibration.

For correct installation, the conductor should be stripped to the appropriate length and inserted into the terminal barrel before crimping with a suitable tool and die. The finished connection should be inspected for secure conductor retention before being attached to the terminal stud. The fixing should then be tightened according to the equipment manufacturer's recommendations. Selecting the correct conductor size and terminal type is essential for achieving a reliable electrical connection.

Typical Applications

• Industrial electrical control panel wiring.
• Electrical equipment and component connections.
• Machinery wiring and automation installations.
• Terminal stud and screw connection points.
• Electrical distribution and control equipment.
• OEM equipment assembly and manufacturing.
• Electrical maintenance and cable replacement.
• General-purpose electrical cable termination.
