Abstract

A distribution block for telecommunication and data transmission applications, in particular for the main distribution frame of telephone and data lines. The distribution block includes insulation displacement contact elements for the connection of the subscriber cables as well as of the exchange office cables. One-piece contact springs are disposed in the interior of the modular-design distribution block. A mounting bracket, in particular for receiving distribution blocks is provided including a U-shaped tub. A device for guiding cables is rotatably moved in a partial section, and with cable guide portions. A reduction in size, an improvement of connection tasks, the individual protection of double wires, a reliable grounding and a cable guiding which is substantially resistant to buckling and bending are secured, is achieved by that one-piece contact springs disposed in the interior of distribution block. These springs are formed by insulation displacement connection contacts at the front and rear sides of the block by a telephone contact in a central section, the phone contact being composed of at least two contact surfaces which may be double contacts, and by a support surface. A tongue acts on the support surface with a cam. A tapping contact is provided in the front section of contact spring. A mounting bracket is provided with a tub bottom and contact lugs for the establishment of an electrically conducting and of a mechanical connection and openings for the insertion of protection plugs or the like. A device for guiding cables is provided including a rack frame or the like rigidly disposed cable guide portions that are positioned upwardly and downwardly offset to cable guide portions.
