Abstract

Subscriber lines (10) are secured e.g. by screw clamps (19) to contact parts (18) which project from stripping connection terminals (7) with contact flanges (11) into terminal slots. The connection terminals (7) are joined to stripping terminals (4) to which are connected the internal lines leading to the exchange equipment. The flanges (11) on the inner ends of the contact parts (18) are inserted into the connection terminals (7) of contact pieces (3) in the housing (20). USE/ADVANTAGE - Esp. in a telephone exchange. A distributor moulding with little modification of individual parts is accessible for connection of lines having widely different nature and thickness.

Description

Overhead lines (10) of very different wire thicknesses, which lead to the subscribers, are connected to the contact elements (18) by means of screw clips (19), which extend into the terminals of the cutting clamps (7). These connection terminals (7) are provided with cutting terminals (4) to which the internal conductors (5) leading to the switching device are connected.

This makes it easy to connect the contact elements (18) to the connection terminals (7).

BACKGROUND OF THE INVENTION The present invention relates to a line arrangement for telecommunication, in particular a telephone apparatus, where switching wires of a very different nature and thickness, such as overhead lines, can be connected to the line organizer.

Such apparatus is known, for example, from EP-0209 741 A2 (= AU-Appl. No. 60571/86, IE-Appl. No. 1980/86). Accordingly, the line organizer consists of a strip-like elongated housing having cutting clips arranged side-by-side for connecting the switching wires. The cutting clips are part of the contact elements on which the additional protruding screw clips are welded. For example, the wires leading to the telephone subscribers can be connected to these screw terminals. In countries where telephone subscriber density is relatively low, overhead lines are typically designed as backbone lines, which may have multiple core diameters relative to telecommunication equipment's multiple switching cables. Their materials are relatively hard, high strength and stiff.

It is also known according to EP-0 323 574 A1 (= AU-Appl. No. 27527/88) a sorting strip in which U-shaped contact elements are arranged side by side in the longitudinal direction of the sorting strip. The contact elements have cut-off clips at both ends of their stems, to which switching wires of small diameter and small diameter can be connected. However, such clips are not suitable for connecting overhead lines.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sorting strip which, with a slight modification of each element, is also suitable for connecting air ducts.

The present invention solves this problem by providing a line arrangement for telecommunication equipment in which the various switching wires are connected to suitable contact elements, such as screw terminals, and the contact elements have a contact stem which fits into the respective fork-like connector terminals.

Here, the contact elements leading to the overhead lines are pressed into the terminal block to form a contact instead of a thin switch wire. This connection process corresponds to the pressure of the switching wire at the connection terminal. Expensive welding of the contact elements leading to the subscriber leads is therefore not required. Thus, it is possible to use materials of different thicknesses and types for the connection terminals and the contact elements leading to the ducts. These unique materials are thus optimally matched to the various functions. Modification of the contact elements carrying the connector terminals is not, or only slightly necessary. The housing housing these contact elements may also remain substantially unchanged. The contact elements leading to the ducts may, for example, end in screw terminals.

Connecting three-wire power lines known from DE 3 418 355 to plugs that can be plugged into socket strips. The plugs have screw terminals which are connected to the plugs. These protrude from the plug and can be plugged into the fork-like contacts of a power rail.

The common housing of the contact elements and the connection terminals can be produced at a significantly lower cost than the individual plugs for the individual wires that could be attached to the sorting strip. The individual plugs should then be secured, for example, with screws to the grid to accommodate the high forces involved in connecting the wires. Placing the contact elements and the grid and the terminal clamps in a common housing results in a cost-effective, compact and stable line organizer to which the overhead lines can be directly connected.

In a preferred embodiment of the invention, the contact elements are formed as claw spring clips.

The claw spring clip may be designed as a standard commercial terminal clip such as that found in light switches. Wires with a large diameter difference can be easily and securely attached to such spring clips.

In a further preferred embodiment of the liner according to the invention, the release arms of the spring clips are resiliently disposed on a common rod which, with their projecting pins, fits into the recesses of the arrangement bar.

These release arms are required to compress the spring arms of the spring clips to release the fixed wire. Due to the fixing on a separate rod, it is possible to remove the release rods covering the spring clips. All this facilitates the replacement of the contact elements for the overhead lines. Because the connectors are accessible, conventional wires can be directly connected to the connector terminals instead of individual overhead lines. These cables do not require spring clips. The release arms can then be reinserted. The arms also cover the contact portions.

The invention will now be described in more detail with reference to the embodiments shown in the figure, wherein

1-4. According to Figs. 1 to 4, the strip (1) has an elongated housing (2) in which transverse contact plates (3) are arranged side by side in the longitudinal direction. The contact plates are substantially U-shaped and are formed at one end of the stem (4) as cutting clips to which internal conductors (5) are connected to a switching device. The contact plates (3)

EN 206 797 Β from the base section, the contact springs are bent to the side (6) to connect protected plugs. At the other end, the contact plates (3) are formed as terminal forks (7), which are similar to or similar to the cutting terminals for connecting the switching wires.

The housing (2) expands laterally beyond the contact plates (3). In this section, the connection terminals (7) are provided with contact elements (8), which are formed essentially as claw (9) spring clamps. These spring terminals, known in the art of assembly, such as those used in light switches, are designed so that overhead lines (10) that lead to subscribers and are stripped at their ends are securely contacted by simple plugging.

The contact elements (8) extend into the terminal slots (12) of the connection terminals (11) by means of contact stems and are secured there by contact. The insertion is similar to the insertion of the coupling wire into the cutting clip from the open side of the terminal slot (12).

The overhead lines (10) have two wires as backbone wires, each of which is plugged into two adjacent spring clips (9). Each pair of spring clips (9) is provided with a release lever (13) which is elastically pivotally mounted on the common through rod (14).

This rod comprises projection pins (15) which are releasably inserted in the respective recesses (16) of the housing (2). It is also possible that not all terminal blocks (7) receive contact elements (8). By removing the rod (14) provided with the release levers (13), these connection terminals (7) become accessible, so that ordinary switching wires can also be directly connected.

The part of the housing (2) which receives the spring clips (9) can also be formed as a separate unit, which can be fastened to the base housing of the contact plates (3), for example by gluing. However, the two housing parts can be secured separately on a common carrier.

According to Fig. 5, on the other sorting strip (17), instead of the spring clips (Fig. 2), the other contact elements (18) are provided with screw terminals (19), to which also air ducts (Fig. 2) can be connected. The inner ends of the contact elements (18) are also formed by contact pins (11) located in the connection terminals (7) of the contact plates (3). These are taken up by a housing (20) which is similar to the other sorting strip (2) in the area of the contact plates (3).
