Ring / Battery Crimp Terminal Connectors

Ring terminal connectors are an essential component in electrical systems where a reliable and secure wire connection is required. These connectors create a strong, crimped or soldered bond between a wire and a screw or stud-type terminal, making them ideal for automotive, industrial, and marine applications. Whether you're working with heavy-gauge wires or smaller electronics projects, you'll find the right ring connector for the job right here.

What Are Ring Terminal Connectors?

A ring terminal connector consists of a metal ring that is crimped onto a stripped wire. The ring end is then bolted or screwed down to form a tight electrical and mechanical connection. This secure design makes them perfect for applications exposed to vibration, such as engines or machinery, where disconnection could pose a safety risk or cause a failure.

Also referred to as circle wire connectors or wire ring connectors, they come in a variety of sizes, insulation types, and metals depending on the voltage and amperage requirements of your project.

Types of Ring Wire Connectors We Offer

Our extensive inventory includes:

• Insulated ring terminal connectors – Vinyl, nylon, or heat-shrink insulation for added protection and strain relief.
• Non-insulated ring connectors – Ideal for environments where insulation is not necessary or when additional heat protection is applied.
• Heat shrink ring terminals – Provide weatherproofing and a tight seal for outdoor or marine use.
• Large gauge ring connectors – Designed for heavy-duty power and ground wires in automotive or industrial settings.
• Small ring connectors – Perfect for delicate electronics and low-voltage applications.

Available in a wide range of stud sizes and wire gauges, our ring terminals ensure that you’ll find the right fit for your cable and application.

Common Applications for Ring Terminal Connectors

Ring wire connectors are commonly used in:

• Automotive wiring – for battery cables, grounding wires, and electrical systems.
• Marine electronics – thanks to corrosion-resistant materials and weatherproof variants.
• Industrial control panels – for terminating wires on circuit breakers and terminal blocks.
• Household appliances – for stable, solderless connections inside devices.

The circular shape of the terminal ensures maximum surface contact with the mounting point, which means lower resistance and better current flow, even under demanding conditions.
