A split-50 M-type 66 block with bridging clips attached. A 66 block is a type of punch-down block used to connect sets of wires in a telephone system. They have been manufactured in four common configurations, A, B, E and M. [a] A and B styles have the clip rows on 0.25" centers while E and M have the clip rows on 0.20" centers.
A punch-down block (also punchdown block, punch block, punchblock, quick-connect block and other variations) is a type of electrical connection often used in telephony. It is named because the solid copper wires are "punched down" into short open-ended slots which are a type of insulation-displacement connector .
Terminal blocks (also called terminal boards or strips) provide a convenient means of connecting individual electrical wires without a splice or physically joining the ends. Since terminal blocks are readily available for a wide range of wire sizes and terminal quantity, they are one of the most flexible types of electrical connector available.
Terminal symbol A terminal strip, to which wires can be soldered. A terminal is the point at which a conductor from a component, device or network comes to an end. [1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.
Punch-down blocks are intended to connect individual conductors punched down into each position in the block with a special punch-down tool. Punch-down terminations are also generally seen in telephone and network connectors, in patch panels and distribution frames , and in telephone equipment such as PBXs .

It is also known as "Combicon", which might be a Phoenix brand name; or more generically as a "pluggable terminal block" or a "two piece terminal block". [2] [3] The Euroblock is a solderless connector that uses screw terminals to clamp connecting wires. Once the wires are installed, the entire assembly is plugged into a matching socket in the ...
A punch block using krone contacts Cross connect field with krone connectors. Krone LSA-PLUS (or simply krone) is an insulation-displacement connector for telecommunications. It is a proprietary European alternative to 110 block. The Krone LSA-PLUS system is not limited to telecommunications, as it is also popular in broadcast systems, where ...
