Before soldering, tires connecting to terminals shall be securely
3.1.35.2
fastened to the terminals by crimping the terminals firmly upon
the wire, or the wire upon the terminals, except in cases where
the mechanical configuration of the wire or design of the terminal
is such as to hold the wire securely in place without crimping,
or where the small size of the terminal makes crimping imprac-
ticable. For example, crimping is considered impracticable where
a relatively large wire goes through a thin section terminal as
on an electron tube socket, wafer switch, potentiometer, and the
like, in which a wire hole is usually provided and crimping
wrapping, or twisting is not feasible. The extent of the crimping
or wrapping shall be just sufficient to hold the wire in place
before soldering. In general, one-half to one turn of wire
about a terminal will be sufficient for mechanical securing of
the wire. In no case shall electrical connections be made by
clamping wires smaller than AWG No. 14 between metal parts
other than solderless terminals.
Whenever bolts, screws, nuts, studs, or rivets are used in a
3.1.35.3
r-f circuit, all connections thereto shall be securely soldered,
except that soldered connections are not considered practicable
at studs of molded phenolic capacitors meter terminals, and
other places where damage from overheating may result.
In no case shall electrical connections depend upon wires, lugs,
3.1.35.4
terminals, and the like, clamped between a metallic member and
an insulating material of other than a ceramic or vitric nature.
Such connections shall be clamped between metal members, pre-
ferably such as an assembly of two nuts, two washers, and a
machine screw. If such an assembly is not used, and maintenance
of a tight connection depends upon the resistance of an insulating
material of other than a ceramic or vitric nature to conpressive
stress or shear, such connections shall be securely soldered.
Whenever wires are run through holes in metal partitions, shields,
3.1.35.5
and the like, less than 1/8 inch in thickness, the holes shall be
equipped with suitable grommets or punched and rolled for mechani-
cal protection of insulation otherwise subject to abrasion.
Panels 1/8 into, or more, in thickness either shall have grommets
or shall have the hole edges rounded to a minimum radius of 1/16
inch. Care shall be exercised in the running of hookup wire to
insure that it is not carried over or bent around any sharp
corner or edge which might in time cut through the insulation.
In order to prevent deterioration of the conductor by heat, care
shall be taken to insure that wiring is not exposed to excessive
temperatures and that it cannot come in direct contact with heated
parts.
