Terminal ring connector BLOW 43-014# insulated, screw 4.3 mm for 4.3 mm cable

Insulated ring terminal connector BLOW 43-014# is designed for crimping onto wires with a 4.3 mm conductor end and for mounting under a 4.3 mm screw. The insulated sleeve provides electrical insulation and strain relief while the ring terminal ensures a reliable electrical and mechanical connection to screw-type terminals. It is suitable for control panels, automotive wiring, household appliances and various electrical installations where a secure, crimped ring connection is required.

Advantages

The insulated ring shape offers stable contact and prevents accidental wire pull-out when properly crimped. The insulation reduces the risk of short circuits and improves safety in compact assemblies. The metal ring is formed for consistent contact area and compatibility with standard 4.3 mm screw terminals, enabling predictable electrical performance and simplified installation.

Suitable for

• Terminal connections on control panels and relay blocks
• Automotive and vehicle electrical systems
• Household appliances and consumer electronics
• Industrial equipment and general-purpose wiring

Key specifications

• Terminal type: insulated ring connector
• Nominal screw diameter: 4.3 mm
• Wire end style: crimpable ring
• Insulation: polymer sleeve for electrical isolation and strain relief
• Material: conductive metal contact with insulating jacket
• Typical applications: screw-terminal connections in electrical assemblies

How to use

Strip the wire to the appropriate length so the conductor fully inserts into the metal barrel of the terminal. Insert the conductor into the barrel until the insulation meets the sleeve. Use a suitable crimping tool sized for the terminal to compress the barrel onto the conductor, ensuring a secure mechanical and electrical connection. Place the ring over the target screw and tighten the screw to the manufacturer-recommended torque for the terminal and mating hardware. Ensure the insulation covers exposed conductor and that the connection is mechanically secure.

Usage recommendations

Use the correct crimping die and tool for insulated ring terminals to achieve reliable crimps; verify connections visually and with a pull test where appropriate. Select terminal sizes and screw hardware that match the 4.3 mm nominal screw diameter to ensure proper fit and electrical contact. Avoid overheating the insulation and protect terminals from corrosive environments unless additional protection is applied.
