CRIMP TERMINATION

A crimp termination can be definied as the joining together of conductor and terminal through the proper mechanical displacement of the materials by squeezing the connector sleeves onto the conductor. The process is realized through a mechanical bond in lieu of thermal alloying. The primary concern in the selection of this termination method is proper execution of the crimp. This can only be realized through selection of proper tools and terminals, including contacts, lugs, etc., and wire sizes. Tools are now available which will properly execute the termination by means of ratchet, preset, positive cycle mechanisms. These tools will function properly over extended periods of time, with the augmentation of thorough test sampling cycles. This method lends itself well to semi- and fully-automated production methods. Crimp terminations offer the advantages of the selection of wire, insulation, and terminals without concern for thermal characteristics. This method also permits miniaturization and subminiaturization of circuitry with excellent mechanical and environmental parameters. The greatest single advantage of crimping, compared to soldering, is elimination of the human element always present in soldering. When proper tooling is used, crimps are as consistent as the tolerances that can be maintained on thejoined parts.
