Work procedure

1.Disassembly of connector

(1)To remove the plug, remove the set screw, fit a receptacle adaptive to the P

shell unit to fix, and remove he cord tube.

(2)To remove the cord clamp, remove the cord tightening screws. (Note 1)

2.Connection

2.1 Soldering type

(1)Use the cable so that the conductor can be soldered properly into the solder

pot with the cable sheath diameter adaptive to each cord clamp.

(2)After the terminal treatment of the cable with a size given in Table 1, thread

on the cable the clamp, washer, gasket, cord tube and coupling in this order

and direction as shown above.

(3)Solder 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 to meet the C size. (Note 2)

2.2 For crimping type connectors

(1)Please make sure to use a cable with the correct outer diameter for the cord

clamp. It is also important that the wire and its outer diameter are appropriate

for the crimp contacts.

(2)Pass the cables in order through the 1) tightening fitting, 2) washer, 3)

gasket, 4) cord tube, and 5) coupling in the direction shown on the above

figure, following terminal treatment as shown in Table-2.

(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,

please make adjustments so that the dimension for Section C shall be

satisfied. Note 2 )

3.Assembly of connector

(1)Fit the connected P shell unit to the receptacle fixed with a vice or the like.

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 preventing the cable from being ratated. And, Loctite Japan Co

Ltd. is recommended to be applied as locking. (Note 3)

(3)Torque the set screw to 0.2 to 0.25N·m.

(4)Torque the cord tightening screw (two positions) to 0.65 to 0.7N·m.(Note 1, 3)

Plug assemblies procedure

The receptacle side is omitted because no special procedures are required.

Diagrammatical view

Note 1 : Not required if a simple type cord clamp is used.

Note 2 : Please maintain this dimension until assembly is complete.

Note 3 : Cable clamping force, cable rotation force, and others aspects may differ depending on the cable construction.

We recommend that you verify the suitability of the cable assembly before use or production.
