Tips: Termination way of circular connector
Termination way refers to the connection way between the contact pair of electrical connector and wire or cable.
Solder termination: Wire is welded in the solder cup of contact.
Crimp termination: Wire is crimped inside the crimping cylinder of contact, which can be separated from circular connector by contact withdrawal tool. The dismountable contact can both plug in the front end and back end of circular connector. Dismountable contact in the back end is suggested.
The use environment and requirements for field repair are considered in the choice of termination way.
Circular connector has simple and firm locking mechanism, easy to seal, insert and dismantle. Circular connector has 2/3/4/5/6/7/8/9/10/11/12/14 pin, different shapes of plug & socket to select.
