It is called TB110 or terminal block 110 to the type of block system for the connection of certain wiring systems, such as in network installations, typical connector used in most patch panels.

The denomination 110 refers to the type of encapsulation available to the connectors, a crimp system that needs to press the connection cable downwards.

One of the advantages of this type of connectionres is its small size, guaranteeing more connectors in less space.

This type of connector requires a special tool, called an impact tool, which performs two functions at the same time.

Once the cables are placed in their corresponding positions we will use the crimping tool pressing down with the side of the blade on the outside, thus getting to press the cable towards abajo, crushing it, in turn the blade will cut the excess wire.

The RJ12 connector is a phone that has the same dimensions as the RJ11 connector, the difference is that it has 6 contacts, instead of 4.

This connector is for a cable crimp wire 6 and has 6 positions (where the blades are housed) and 6 contacts (6P6C), implying that all are used.
