Description

1 95088

The invention relates to a cross-connection strip for a telecommunication plant, in particular for a telephone plant, in which an elongate cross-connection vibration is provided with longitudinally spaced-apart contact strips 10 and for outgoing wires.

Such a cross-connect strip is known, for example, from DE 35 09 523 A1. According to it, the contact parts have contact points for protective plugs and disconnection or test plugs.

The contact parts can be formed in one or two parts. The two-part implementation has contact springs that press flexibly and open against each other. All contact points and terminals can be reached from the operating side. The intersecting terminals of the frequently changed output cross-connection wires 20 are located so high above the rear surface of the cross-connection strip that they extend past the inserted protective plug. The contact parts thus extend mainly in the insertion direction. The contact parts are adapted to the required shape mainly by bending and are guided and fastened between two housing parts of the cross-connection strip. The isolating contact points are then approximately halfway in the height direction between the contact points of the protective plugs and the terminals intersecting the insulation of the cross-connection wires.

The invention is based on the object of reducing the dimensions of the cross-connection strip and simplifying the manufacture.

This object is solved by the invention according to claim 1.

Since all material levels of the contact parts are oriented in the direction of use, the basic shape of the contact parts can be produced 95088 2 mainly by cutting cutting. The base of the contact parts is transverse to the longitudinal direction. The intersecting connection terminals are bent in the longitudinal direction by a simple bending of the base. The spring arms of the separating contact 5 can also be bent in the same way, so that two sufficiently resilient contact springs are obtained. Because the spring arms operate from the base, their height can be kept low.

10 The contact points of the protective plugs are close to the cutting terminals of the cables that are rarely changed. The contact points of the test and isolation plugs are located between the contact points of the protective plugs and the cutting terminals of the outgoing cross-connection wires. This allows the protective plug to be kept at a sufficient distance from the terminals of the cross-connection wires so that it does not prevent the connections from being made. The intersecting connection terminals of the cross-connection lines can then be placed correspondingly downwards, so that the structural height of the cross-connection strip is considerably reduced. By attaching the contact parts to one part of the housing, the contact parts can be installed much more simply. The contact parts only need to be pushed from behind into the corresponding placement compartments of the housing part on the drive side. The lid-like back of the case only has a closing function.

In the embodiment of the invention according to claim 2, in addition to the seldom-needed cutting terminals, the protective plug also covers the respective wiring space of the respective cable conductors. This provides enough ti-30 laa to connect the cross-connect wires and connect the test plug next to the protective plug.

In another development of the invention according to claim 3, the test plug can rest on the entire width of the cross-35 connection strip, as a result of which the plug contact points are less loaded.

The invention will be explained in more detail by means of an exemplary embodiment shown in the following drawing.

In the drawing, Fig. 5 shows a plan view of the cross-connection strip and the wires connected thereto, Fig. 2 shows an enlarged section of the cross-connection strip along the line II-II in Fig. 1, Fig. 3 is a plan view of the contact parts of the cross-connection strip

According to Figure 1, the elongate cross-connection strip 1 has connection terminals 2 intersecting the insulation, which are arranged on the drive side of the cross-connection strip 1 on both longitudinal sides. Connected to the connection terminals 2 are, for example, cross-connectable wires 3 from subscribers and, for example, output wires 4 leading to the relay device 20. The connection terminal 2 of the incoming line 3 and the opposite terminal 2 of the output line 4 are parts of a one-piece contact part 5. The protective and test plugs can reach the cross-connection strip 1 of the contact part through the plug openings 6, 7 of the housing 8, 9.

According to Figures 2 and 3, the housing consists of a front part 8 on the drive side and a cover-like rear part 9. The front part 8 has open compartments for contact parts 5 30 facing the rear part 9. The contact parts can be inserted into the front part 8 simply by pushing from behind and they are positioned and • fully attached to the front part in the correct position. The contact parts 5 are aside and perpendicular to the rear part 9, which is locked to the front part 8. The contact parts 5 have a base part 10 running along the rear part 9 between the cutting connection terminals 2, which connects the cutting connection terminals 2 to each other. The intersecting connection terminals 2 are turned at an angle of 90 ° by bending the longitudinal direction of the cross-connection strip 1 - 77— -. ____ 95088 4 si. In addition to the cutting terminals 2, cut-out fork-shaped plug contacts 11 and 12 for the protective plugs 13 and the test plugs 14 protrude from the base part 10. The plug contacts 11 and 12 are transverse to the longitudinal direction of the cross-connection strip 5 1 and parallel to the base part 10. The contacts are oriented by bending in the middle of the cutting terminals 2. This facilitates the visual alignment of the plug to the cutting terminals 2. The plug contacts 11 are also suitable for connecting a cable plug.

10

The protective plug 13 has push-in tabs 15 which are inserted between the flexible branches of the plug contacts 11. The push tabs 15 are arranged eccentrically on the protective plug 13. The protective plug covers the intersecting terminals 2 of the outgoing wires 4 and extends from the longitudinal side past the connection strip 1 by the width of the wiring space of the outgoing wires 4. The test plug 14 is likewise provided with push-tabs 16 inserted between the flexible arms of the plug-in contact 12. The push tabs 16 are likewise positioned 20 eccentrically on the protective plug 13 offset. This allows the plug contacts 11 and 12 to be placed close together so that the overall width of the cross-connect strip can be kept small. The protective plug 13 and the test plug 14 are placed close to each other on each other. The test plug 25 covers the relevant connection terminals 2 of the wires 3, e.g. from the subscribers. These wires can be made as cross-connection wires leading to another part of the cross-connection device. Since wire tests and wiring changes cannot be performed simultaneously, the test plugs can be pulled out when connecting the wires.

* According to Fig. 4, the plug contacts 12 (Fig. 2) have been replaced by isolating contacts 17, which are separated from each other by the push-tabs 16 of the test plug 14. Instead of the push-in tabs of the test plug 14 35, it is also possible to push the push-fit tabs of the isolating plug between the disconnect contacts 17 to disconnect. When the plugs are pulled out, the isolating contacts 17 are closed. The contact portions 19, 20 are made 5 95088 in two parts and are connected to each other via a disconnect contact 17 with the plugs pulled out. The separating contacts 17 have two spring arms 18 bent in the longitudinal direction of the cross-connection strip 1, which are approximately parallel to the pins 2 of the connection-5. The spring arms 18 are formed so that they can be placed in the same housing as the plug contacts 12 of the protective plug 14.
