Tips: Insulating mounting plate of circular connector
Insulating mounting plate is called base or insulator which is used to arrange contacts according to the wanted position and distance and ensure the insulation among contacts and between contact and shell. Good insulation resistance, voltage resistance and workability are the basic requirement for choosing insulating materials for insulator. The materials of insulator are generally composed of plastics, silicone rubber and pouring sealant with good electrical conductivity. Generally, thermoplastic plastic and thermosetting plastic are adopted.
Circular connector has simple and firm locking mechanism, easy to seal, insert and dismantle. Circular connector has 2/3/4/5/6 pin, different shapes of plug & socket to select.
