The RJ-11 is mainly used to link telephone networks connector. It is small and has four contacts measures to support 4-way 2 cables. It is the most widely used globally for connecting conventional telephones, which generally tend to use only the two central threads to a single line or a twisted pair connector. And the four wires are used only for telephony equipment special using double line or two telephone pairs. After crimp the cable, it is almost impossible to disarm the RJ-11 without causing its deactivation.

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.
