<Fixing the connector>

Slightly widen the external conductor of the coaxial cable, which is crimped to a contact on the internal conductor, in order to smoothly enter the shell inside the external conductor. Press in the external conductor end of the coaxial cable to just before the crimping part of the shell and put the sleeve into the crimping section. Then press in the coaxial cable until a ÒclickÓ sound can be heard. Confirm that the contact end point touches your finger cushion.

<Crimping external conductor>

Crimp the external conductor.

Insert thoroughly the sleeve into the crimping section of the shell and crimp. Put the sleeve in the hexagonal dice and closely stick the shell to the crimping dice. Pull the moving frame to the fixing frame side while pressing the coaxial cable and shell from both sides, and crimp until the ratchet is removed.

(Crimping width: 10 mm)

*Use the crimping tool in the direction shown in the illustration right.

Using the crimping tool in the reverse direction will not crimp correctly.

Completely put into the crimping section.

<Insulation test>

Insulation test of shell and contact

Using a tester, check the conductivity between the internal conductor and the external conductor in the connector. When the indication of the tester shows ∞ ohms, the insulation is appropriate.

<Conductivity test>

Conductivity test

After short-circuiting the one end of the connector crimped to the c o a x i a l c a b l e , c h e c k t h a t conductivity is attained.
