Tips: Shell of circular connector
The shell of circular connector consists of joint, shell, locking mechanism and rear cover, and is used to provide support and mechanical protection for built-in insulating mounting plate and contact pins. On the structures of plug or socket there are many locating keys and grooves that are used to provide accurate location when plug and socket are connected. Most of circular connectors have locking mechanisms, which provide connection and locking functions for the connection of plug and socket. Meanwhile, socket (fixed circular connector) also provides fixed device to fix circular connector onto equipment. Shell is made of aluminum, copper and stainless steel. The proportion and performance of materials are subject to different use environments and occasions. The space flight and aviation industry needs light electrical connector, so its shell is generally made of workable and light aluminum material.
Circular connector is used for connecting component and cable, cable and cable. It is a set of one plug and one socket, has simple and firm locking mechanism, easy to seal, insert and dismantle. Circular connector has 2/3/4/5/6/7 pin to select.
