In IEC connector or cable with a base (usually plastic) and a plug to connect to the socket (plug), if we put these two things we would get the named SCHUKO is the overall connector. The schuko not determine the type of connector. It would be determined by the specification of the International Electrotechnical Commision (IEC). We leave a small sample of Schukos internationally.

Within the different types of electrical cables we can find single or multifilament cables. The difference lies in the number of conductors that make up the cable. Single wire cables contain only a single conductive wire, whereas multi-wire cables contain more than one wire. Do not confuse multifile (A) or single wire (B) with monopolar (C), bipolar (D) or multipolar (E) cable. Monopolar cables have only oneSingle conductor, bipolar cables have two conductors, while multi-pole cables have more than two conductors. It may be said that any unipolar, bipolar or multipolar cable can be single-ended or multi-stranded. In the case of single wire cables we will talk about rigid cables, whereas the multifilament cables will be flexible.
In the following table you can see the difference between them.
