NDT Circular Electric Connector for Nondestructive test equipment

Details:

1, use
YW1 series small circular and quick separation electric connector is used to connect the current of a variety of electronic equipment.
 
2, structural features
This series of products coupled by bayonet locking.  Fast plugging and separation, the use of the cable is convenient, and the contact is reliable.
 
3, Connection and Separation
When connecting, make the alignment on the chases between plug and receptacle first, then insert the plug into the receptacle, rotate hats of the bayonet clockwise until you find a convulsionary feeling caused by the clamp falled into the spiral groove or a "kacha" sound is made, and to check whether the bayonet cap is in instructed place or whether the clamp has been inserted into the chase. When separation, pushed bayonet cap forward slightly, and rotate hats of the bayonet counter-clockwise, then it will be separated after back pulling.
