RS Pro Tubular Ring Terminals

RS Pro range of heavy duty tubular ring terminals made from copper with a tin plating. These heavy duty tubular ring terminals are ideal for use on multi-stranded cables. Versions of these ring terminals are available with a flared or a chamfered entry for ease of wire insertion.

Features and Benefits

• Robust, thick-walled design
• Closed barrel ensures crimp terminal fits securely around the cable
• Copper body material provides high conductivity and is easy to crimp
• Tin plating on crimp terminal provides resistance to corrosion, added strength, a reduction in friction and makes it easier to solder
• Funnel-shaped internal barrel for easy wire insertion

Applications

Non-insulated wire terminals are used in applications where there is not any danger of someone short-circuiting the connection by inadvertently touching it. These crimp ring wire connectors are used in a wide range of industries for connecting multi-stranded power cables to electrical components in more heavy duty applications. Applications include cabling and wiring in industrial control systems and industrial machines, automotive applications, communication equipment, power supplies and domestic appliances.

Selecting the Correct Ring Terminal Size

When selecting the right ring terminal for your application, you should consider the following:

• The wire gauge mm (metric) or AWG (American Wire Gauge) of the wire or cable you are using
• The stud size to which you will be connecting the ring terminal.
• The inner diameter of the ring terminal

How to Crimp a Ring Terminal

Firstly, select the correct sized ring terminal. Strip the end of the wire and cut it to the same length as terminal. Insert the wire into the terminal barrel making sure no bare wire is visible. The crimp terminal is then ready to be crimped on to the end of the cable using the correct crimp tooling. These crimp tools include a heavy-duty ratchet crimping tool or a hydraulic crimping tool. The handles of a ratchet tool will remain locked until a full crimp cycle is completed which will prevent partial crimps. The barrel of the ring terminal is simply inserted into the appropriate crimping section. The tool handles can then be squeezed together until the ratchet mechanism allows them to be released. A heavy-duty hydraulic crimping tool will provide an audible click when full crimp pressure is achieved which also ensures the crimping cycle is complete. The crimped ring terminal can now be placed over the stud or post and secured in place with a nut or by soldering.

Suitable Crimp Tools

Heavy duty hand held crimp tool (stock number 445-611)
Hydraulic crimp tool, (stock number 445-885) and die set (stock number 454-873)
