Typical Applications:

Splice crimps are used in a wide range of industrial, commercial and domestic applications. Splice Connectors are used to make quick splices or connections with two or more pieces of wire. These splices are normally crimped or soldered so that the power conducted from the source cable to the next cable is transferred at inacceptable conductivity and pull-out resistance performance level. They can be found almost anywhere where an electrical connection is required. Some of the most common are

• Industrial control systems
• Automotive and transportation sector
• Machine building
• Electrical and electronic equipment
• Commercial and domestic appliances


Is there a crimp tool that you can use for crimping connectors?
Any good quality ratchet style crimp tool or plier tool designed for crimping terminals would suffice. RS PRO offers a range of reliable, cost-effective tools. For crimp tools please see stock numbers 241-4710, 445-611, 534-806 and 445-885.

What is the difference between un-insulated and insulated crimp tools?
