6.1 Spring Clamp Terminal Block
This section explains the wiring for a spring clamp terminal block.
Applicable wire
A wire that can be connected to a spring clamp terminal block is as follows.
Wire end treatment
Strip the cable jacket approximately 10 mm from the tip, and connect a wire ferrule to the stripped part.
If the stripped part is too long, the exposed wire may touch a material part of the terminal, and it may result in electric shock or
short-circuit among the adjacent terminals.
On the other side, if the stripped part is too short, it may cause contact failure to the spring clamp terminal.
Depending on the thickness of a sheath, it may be difficult to insert into an insulation sleeve. Select the wires by referring to
the external dimensions.
The following table shows wire ferrules and tools for the wire ferrules that are suitable for terminal blocks. If the items other
than those are used, the wire ferrule may not be able to remove. Before using a wire ferrule, check that it can be removed.
