4. SETTINGS AND PROCEDURES UP TO OPERATION

Remarks
Coaxial cable connector connection
This section explains the method for connecting the BNC connector (coaxial cable connector plug) to
the cable.
(1) BNC connector and coaxial cable configuration
(2) Method for connecting the BNC connector and the coaxial cable
Point
Take the following precautions when soldering the contact to the internal conductor.
(1) Be sure that the solder does not creep up the soldered area.
(2) Be sure that there are no gaps in or biting into the contact and cable's insulation.
(3) Quickly do the soldering to prevent the insulation from deforming.
Fig 4.3 shows the BNC connector and coaxial cable configuration.

The following shows a method for connecting the BNC connector to the coaxial cable.
(a) Remove the coaxial cable's external sheath as
shown in the drawing at right. Be careful not
to damage the external conductor.
↓
(b) Place the nut, washer, gasket, and clamp on
the coaxial cable as shown in the drawing at
right, and then wrap the external conductor.
↓
(c) Cut the external conductor, insulator, and in-
ternal conductor to the dimension as shown
in the drawing at right. However, to cut the
external conductor to the same dimension as
the clamp's tapered portion, place the clamp
on before cutting.
↓
(d) Solder the contact to the internal conductor.
↓
(e) Insert the contact assembly in (d) into the plug
shell, and screw on the plug shell nut.
