Work Operation Procedures
1. With regard to cables, the wire to be used should have a conductor with a nominal cross-sectional area of 0.08 mm2
(AWG#28) or less in a finished form suited to each size.
2. First pass the cable bushing and the plug body in order over the cable, then cut the end at the dimensions indicated in the
above diagram.
3. Mount the P shell unit in the wiring jig and perform the solder wiring.
4. Use the cable crimping jig (HR10A-TC-02) to fix the clamp fitting to the cable.
5. After performing the wiring, tighten the plug body to the screw portion of the P shell unit using the specified torque (in the
above table).
6. Tighten the set screw so that the tip of the set screw falls into one of the two bosses of the clamp fitting. Note that the
tightening torque of the set screw is from 0.3 to 0.4 Nm.
7. Put the cable bushing over the plug body and complete the work.
Note that the use of paint lock (e.g., Locktight 263 manufactured by HENKEL JAPAN LTD.) is recommended on the
screw portion to prevent loosening of the P shell unit.
The aforementioned work procedure is for the soldered type. In the case of the crimp-style type, Steps 1 and 3 are changed as
follows:
1. With regard to cables, the wire to be used should have a conductor with a nominal cross-sectional area of 0.05 mm2
(AWG#30) in a finished form suited to each size.
3. Crimp a suitable crimp terminal to the conductor portion of the cable, then fit into the housing of the P shell unit.
Cable Assembly Procedures
The outline of wiring work for this diagram uses the soldered type as an example.
The jack side is also based on the work outline of the plug: however, the receptacle side does not require a special work
outline and has been omitted because of this.
