History and Development of Crimping
– Soldering wires has been common for at least a century
– Crimp terminals came into use in the middle of the 20th century
– AMP Incorporated introduced crimp barrel terminals in 1953
– Cannon Brothers experimented with machined contacts integrating crimp barrels in 1957
– Several standards for crimp connectors were published in the 1960s
Characteristics and Theory of Crimping
– Crimping is gas-tight, preventing corrosion
– Crimped connections are mechanically stronger than soldered ones
– Crimping can be used for cables of both small and large cross-sections
– Crimping is performed by inserting the terminal into the crimp tool
– The resulting connection may appear loose at the edges but is swaged or cold-formed in the middle
– Crimp-on connectors are attached by compressing them tightly around the wire
– Effective crimp connections are gas-tight and resistant to vibration and thermal shock
– There are two main classes of wire crimps: closed barrel and open barrel
– Crimping is also used to join wires to multipin connectors
– Crimp plug-and-socket connectors can be rear release or front release
Quality and Guidelines for Crimping
– A reliable crimped connection requires components from the same manufacturer
– All strands must be deformed enough to cold-flow into the terminal body
– The compression force should be neither too light nor too strong
– The connector body should not be overly deformed
– Wires and insulation must be in solid working condition without any damages or signs of wear
– Crimp Quality Guidelines provide standards for achieving proper crimping
– TE Connectivity Application Tooling offers resources and guidance for crimping
– The Electronic Installation Practices Manual by the U.S. Navy provides instructions for crimping
– The 2.8 mm Apex Terminal Crimp Guidelines offer specific guidelines for crimping terminals
– Crimp symbols are used to represent different types of crimping techniques
Tools and Equipment for Crimping
– A wide variety of crimping tools exist, designed for specific types and sizes of terminals
– Handheld tools, such as crimping pliers, are the most common
– Crimping tools can also include electrically powered hydraulic types and battery-operated tools
– Crimping tools are used for mass production operations
– Different sources provide catalogs and references for crimping tools
– Manual crimp tools are commonly used for fitting BNC and coaxial connectors
– Coax one-operation stripper is a typical tool used for stripping cables
– Understanding common mistakes and good practices in crimping is important
– E-Tech Components provides cross-sectioning services for crimped connections
– Tensile tests can be conducted to assess the strength of crimped connections
Wire Harness Manufacturing and Additional Resources
– Wire harness manufacturing involves crimping terminals onto wires
– Various terms, tools, and tips are important in wire harness manufacturing
– AMP Standard Terminals and Splices offer reliable options for crimping
– Proper crimping techniques are crucial to ensure secure and reliable connections
– Regular maintenance and inspection of crimped connections are recommended

Crimping is a method of joining two or more pieces of metal or other ductile material by deforming one or both of them to hold the other. The bend or deformity is called the crimp. Crimping tools are used to create crimps.
Crimping is used extensively in metalworking, including to contain bullets in cartridge cases, for electrical connections, and for securing lids on metal food cans. Because it can be a cold-working technique, crimping can also be used to form a strong bond between the workpiece and a non-metallic component.
