Card access(Crimp)The process is to use special tools to apply sufficient pressure to the wires and crimping terminals at room temperature,Plastic deformation,So as to achieve a reliable electrical connection.
The principle of crimping is:When a dedicated crimping tool is used to apply sufficient pressure to the wire and the crimping terminal, the two base metals of the terminal and the wire are in close contact, and the temperature of the crimping area rises at this time, and the diffusion phenomenon occurs, and the two crimping parts An alloy layer is formed between the contact surfaces, so that the two crimping parts are firmly combined into a whole, and a reliable electrical connection is formed.
Compared with soldering, crimping has significant advantages: less process and high production efficiency; crimping is cold processing, does not require power supply, and is not subject to site restrictions; crimping does not require solder flux and does not pollute the environment; and the mechanical properties of crimping Stable and highly reliable. However, crimping requires special crimping tools. The crimping point can only be crimped once. Once crimped, the terminal is irretrievable.prefix = o ns ="urn:schemas-microsoft-com:office:office"
due toMDFAnd the diversity of modules and card connection tools are also different.The clamping knife has the function of clamping the twisted pair into the reed. When clamping, the twisted pair can complete the insulation displacement, splicing, and cutting off excess wires at the same time through the bayonet of the reed and the pressure of the clamping knife. The clamping knife also has auxiliary functions such as wire hooking, wire removal, introduction into the reed slot, positioning, and module installation.
