Wire guide element for a distributor unit in telecommunication systems. The plug connector strips of the distributor unit are secured to the edges of a vertically aligned U-shaped carrier part. A hollow plastic member is used as a wire guide element for the lines proceeding between neighboring distributor units arranged at both sides. With the guide peg present at the under side, this hollow plastic member is plugged, on the one end, onto the upper edge of the leg of the carrier part and, on the other hand, is snapped onto the retainer plate joined in this region to the carrier part at the back side. At least one hook attached to the upper side parallel to the plate also serves for the ordered guidance of lines. At its front side, the hollow member has a slot specifically designed for the insertion of lines.

Distributor unit for attaching and connecting electrical lines in telecommunication systems. A rail (5) is secured in two different positions in a simple manner from a servicing side and is provided for the acceptance of accessory equipment (15). The two positions are in the upper end region of the carrier part (1) vertically aligned with its long side in that the rail (5) is hooked to or, respectively, plugged onto the upper edge of a plate (4) that is rigidly connected to the carrier part (1). The edge of the plate (4) provided for the plug fastening of the distributor unit extends beyond the upper edge of the carrier part (1) in a longitudinal direction. Different accessory equipment is easily attached to the front side of the rail independently of the wiring of the distributor. The parts of the distributor normally covered by the planar extent of the rail toward the servicing side are accessible at any time in the respectively other position of this rail.

A distributor strip is composed of an underpart housing and of a contact part housing mechanically joined thereto. The contact part housing contains the contact parts of the contacts belonging to the line leads in corresponding receptacle chambers. The mechanical joining of the housing parts occurs with the assistance of a plurality of cache elements arranged in a row. Guide elements that engage at the cooperating shape-matched to one another upon joining at present at the end-face limiting wall surface. An accurate guidance of the contact part housing to be introduced and, therefore, a secured position of this housing relative to the cache elements are therefore effected when the two housing parts are joined, for example given the utilization of what are referred to as channel and spring elements. This pre-centering also secures the adhesion of the two housing parts, particularly when such cache elements are present exclusively at one elongate side.

A housing for a protective plug including a surge arrester is composed of a pedestal-like lower portion and of an upper portion which is joined of one piece thereto via film hinges. The upper portion is preferably composed of two halves that, for closing the protective plug housing are pivoted towards one another and mechanically joined to one another by appropriate interlock elements. The lower portion contains receptacle chambers for contacts that, proceeding from a base, comprise a double spring contact downwardly in the plug-in direction and a clamp terminal in the upward direction. Three identical contacts are present that are each respectively connected via their clamp terminals to terminal pins of the surge arrester. A pin-shaped projection extends from the upper side of a distributor strip to serve as cooperating contacts for the double spring contacts. Each such contact also has a pin-shaped projection extending from the bottom side for connection to switching equipment. Also, such pin-shaped contacts may be insulation-pierce contacts. The contact element comprises an offset between the center line of the double spring contact and the actual terminal of the terminal legs of the surge arrester that are in alignment. Given receptacle chambers that are arranged offset relative to one another, the surge arrester can be introduced thereinto on a straight line without a deformation of its terminal legs adapted thereto when the individaul contact elements are introduced into the receptacle chambers in a defined, mutually turned position.

An attachment unit for attaching and connecting electrical lines or cabling wherein the edge region of one side wall of a carrier part, preferably manufactured as an extruded profile, comprises a full-cylinder shape acting as a pivot point which the plug strips are plugged onto with cooperating, hollow-cylindrical cut-out portions. In the position of use, these plug strips are screwed to a screw channel of the carrier part formed in an opposite side wall of the carrier part via a corresponding fastening flange formed at an end of the plug strips. Also, cable and wiring channels are formed through the carrier part by the specific shaping of a side wall of the carrier part and partitions. Further screw channels present in the extruded profile of the carrier part make possible the fastening of a base plate and the fastening of carrier plates, or, respectively, webs that service wiring or cabling or serve for the acceptance of other assemblies. An alternate hollow-cylindrical cut-out portion is provided at the plug strip symmetrically vis-a-vis the position of the fastening flange. Plug strips having posts or terminals arranged above one another on opposite face sides of the plug strip can be employed since the plug strip, having strain-relieving connecting wires, can be turned over by 180 degrees and refastened, using the alternate cut-out portion, for processing of a respective other face side.

Insulation-opening contact sections of contacts for incoming lines exit at one long side of a main distributing strip while insulation-opening contact sections of other contacts for the outgoing lines exit an opposite long side of the main distributing strip. The end sections of the contacts comprise contact poles for producing a separable electrical connection. A channel-like wiring space is limited at the inside by a long side of the main distributing strip. A transverse web extending to the long side divides the wiring space into a wiring space for the service side and a wiring space for the system side.
