Product Wiring Procedure (Plug Side)
Wiring procedure (plug side) schematic
Work Procedure
1. Connector Disassembly
(1) To remove the plug, remove the set screw, fit an applicable receptacle to the P shell unit to fix, and remove the cord tube.
(2) To remove the cord clamp, remove the 2 cord tightening screws. (Note 1)
2. Wiring
2-1 Solder Type
(1) Use the cable so that the conductor can be soldered properly into the solder pot and with the applicable cable sheath diameter used for each cord clamp.
(2) After terminal processing the cable to the dimensions shown in Table-1, apply the fastening bracket, washer, gasket, cord tube, and coupling in that order to the cable in the direction shown in the above diagram.
(3) Solder the wires to connect the conductors to the terminals of the P shell unit. Shrinkable tube is recommended to be used at the connecting part because insulating performance might deteriorate due to solder whiskers or dewing. After connecting, adjust so that the dimensions of the C portion are satisfied. (Note 2)
2-2 Crimping Type
(1) Make sure to use a cable with the correct outer diameter for the cord clamp. It is also important that the conductor and its outer diameter are appropriate for the crimp contacts.
(2) After terminal processing the cable to the dimensions shown in Table-2, apply the fastening bracket, washer, gasket, cord tube, and coupling in that order to the cable in the direction shown in the above diagram.
(3) After crimping the applicable crimping contacts onto the conductor, insert the crimping contacts into the contact holes of the P-shell unit. After inserting, adjust so that the dimensions of the C portion are satisfied. (Note 2)
3. Connector Assembly
(1) Fit the connected P shell unit to the receptacle fixed with a vice or the like and insert into the coupling and cord tube. Torque the cord tube to the level as given in Table-3.
(2) Fit the gasket, washer and clamp. Torque the clamp to the level as given in Table-3 while ensuring the cable does not rotate.
(3) Torque the set screw to 0.2 to 0.25 N·m.
(4) Torque the cord tightening screw (two positions) to 0.65 to 0.7 N·m. (Note 1) (Note 3)
Note 1. Not required if a simple type cord clamp is used.
Note 2. Maintain these dimensions until assembly is complete.
Note 3. Cable clamping force, cable rotation force, and others aspects including waterproof performance may differ depending on the cable construction. Verify the suitability of the cable assembly before use or production.

Product Usage Precautions
- 1. Make sure the power is off before mating or un-mating the connector.
- 2. Use connectors with socket (female) contacts at the power side of the circuit.
- 3. Always use the screw lock function of the connector (state when tightened to maximum degree.)
- 4. Use connectors in combination with other waterproof types.
