Terminals - Wire Splice Connectors

Wire splice connectors are quick connectors that splice two pieces of wire together and are used extensively in many industries and applications. The 62759-1 standard defines the requirements for quality and performance for such splice connectors in the railway industry.

Requirements of the 62759-1 Standard

The requirements for the 62759-1 standard are comprehensive, covering the different types of wire splice connectors, the various materials used in their manufacturing, and their associated parameters such as resistance, pullout force, and insertion life. It also covers requirements for environmental conditions and the types of tests used to evaluate a splice connector. For example, it outlines the requirements for a pullout test, which is used to measure the mechanical forces that hold a wire in the splice connector.

Types of Wire Splice Connectors

The 62759-1 standard provides guidelines for two basic types of wire splice connectors: mechanical and heat-shrinkable. The mechanical splice connectors use a crimping tool to create mechanical interlocking between the two wire ends. Heat-shrinkable splice connectors are used when the wire ends need to be insulated and protected from moisture. They also provide additional protection against vibration and loosening.Both types of wire splice connectors have their own advantages and disadvantages. Mechanical splice connectors provide good tensile strength and are relatively easy to use and install. However, they are not suitable for high-temperature applications, as the force of the crimping can weaken over time. Heat-shrinkable connectors, on the other hand, can withstand higher temperatures and are better suited for vibration-prone environments. However, they require additional tools and steps to install and their performance can be affected by temperature changes.

Design Considerations

When designing a wire splice connector, the 62759-1 standard provides guidance for choosing the right material and considering the factors that affect the performance. These factors include the thickness, hardness, and tensile strength of the material used, as well as the size, height, and profile of the splice connector. The standard also outlines the requirements for the crimping tool and other tools used in the installation process.

Application Field and Working Principle

Wire splice connectors are widely used in many different industries, including automotive, rail, medical, and aerospace. In the railway industry, they are used to splice and mechanically secure cables and wires for signaling systems, power supplies, and telecommunication systems.Their working principle is relatively simple. Two pieces of wire are inserted into the splice connector and it is crimped or heated with a tool. The force of the crimping or heat causes the metal of the splice connector to interlock with the wire, creating an electrical and mechanical bond. This bond is further strengthened by the insulation provided by the material of the splice connector.
