1, 5 Keys system can avoid mis-mating to ensure a correct interpolation.
2, adopt spiral keyway with clamps, which can check the plug and receptacle whether insert a right place by visually and hearing feelings.
3, three clamps installed on the surface of the receptacle (circumferential and even distributing) enter into the corresponding spiral keyways for receptacle connecting ,to the bottom of the keyway, “da” sound of the clamp heard, suggest that plugs in the right place which ensures connector absolutely locking.

Keyways with different angles on the external of the insulation, can be assembled by the producer according to the users’ needs to guarantee the plugs and receptacle with same categories will not be mistakenly inserted. So the same species to the same specifications assembly serial numbers corresponding to the plug and receptacle can be inserted. Different keys assembly corresponding number of plugs and receptacle can not be inserted. The key figure to Angle :

cooperating relations between plugs and sockets 
A, when plug and receptacle couple with each other, if plugs install pins receptacles should install holes, the same to the opposite.
B, plug and receptacle should have to choose a shell with same oil painting on its surface, precedent choosing color is black, army green or nickel plating.
C, appearance quality and operation is same to Y50EX.

Operating manners
1,when the corresponding 2 parts of the connectors connect by within bayonets, rotate bayonet cap to the right direction. When inserting safely, and bayonet in the place of the connecting is locking, a white bayonet pin can be seen through the observation hole on the circle of the connecting bayonet cap.
2, wires of the connector should be corresponding to the contact NO.,  welding time can not exceed three seconds (electric iron shall not exceed 45W).
3, welding-type connector after welding, the plywood or the wire-protecting covering of the electric coat should nip tightly.
4,When 2 parts of the connector have to insert for a long-term (such as storage and use), the safety hole on the connector will be wire linked and nipped tightly with the receptacle.
5, After separation of the two parts of the connectors, the two parts have to cover a dirty-Shield (or to be plugged to a empty receptacle.)
6, no inserting of the pin with receptacle.
7, connector installation, the use of staff should understand performance and usage of the connector.
8,Before un-tightly locking, prohibits using, when there is electric charge, prohibit the separation.
