Tips: Installation way and shape of circular connector
The installation way of circular connector includes front installation and back installation. And the fixing ways include rivet, screw, rand or rapid locking of bayonet lock of connector. There is a kind of connector with plug and socket that both are free-ends, namely cable (neutral) connector.
Circular connector has different shapes. Users choose the shape of circular connector according to the outer structure (straight, right angle), external diameter of wire or cable, the fixing requirements of shell (volume, weight) and whether need to connect a metal flexible tube. For choosing a connector on the panel, the pearance and color should be considered.
Circular connector has simple and firm locking mechanism, easy to seal, insert and dismantle. Circular connector has female plug & male socket, 2/3/4/5/6/7/8/10/12 pin to select.
