electrical characteristics
Contact resistance and rated current
The operation method of the Y50X electrical connector: 1. When the two opposite parts of the electrical connector are connected by the inner bayonet, connect the card cap in the right-hand direction. When securely mated, the white detent can be seen through the inspection hole on the circumference of the connector cap when the connector cap is in the locked position. 2. The connecting wire of the electrical connector needs to be relative to the contact number, and the soldering time is not allowed to exceed 3 seconds (the soldering iron is not allowed to exceed 45 watts). 3. Welded connectors need to be clamped by the clamping plate or wire sheath of the cable cover after welding. 4. The two parts of the aviation plug need to be plugged together for a long time without separation (such as the whole machine storage and on-site use), which can Tighten the safety hole on the connector with the wire connection and the seat. 5. After the two parts of the electrical connector are separated, the dust cover should be closed on the two parts (or the plug pins should be inserted into the socket). 6. Do not insert the needle head and the needle seat against each other. 7. When installing the aviation plug, the user should be aware of the performance and usage of the electrical connector. 8. Before the electrical connector is locked, it must not be powered on. Never separate under load.
The matching relationship between the plug and the seat: a. When the plug and the seat are consistent, if the plug is equipped with pins, the seat should be equipped with holes, and vice versa; b. The plug and the seat should be selected from the same surface: Army green, nickel, or cadmium plating.
