る。 By the way, in this type of electrical connector, it is economically undesirable to manufacture or select and use many types of connectors depending on the outer diameter of the connecting wire, so for example, the applicable wire range is 0.3 to 0.85 mm 2 , 0.5 ~2.0
The wire connection parts 2 and 3 are ranked according to the width of the wire that can be crimped, such as mm 2 .
Generally, the inner diameter of the wire is molded to match the maximum outer diameter of the applicable electric wire.
