Description

Universal strip

The invention relates to a generic strip for telecommunications and data technology, which performs the functions of termination, isolation or connection.

Termination and isolation strips for use in telecommunications and data technology can be fitted with insulation piercing terminal contacts, which correspond to DE2,804,478 and can be wired in a planar fashion. The connection contacts on the cable core side and on the switching side of the switch can be arranged at the same operating level in front. The strip may be locked to the mounting bracket and, if necessary, it may be removed from the mounting bracket using a guiding tool and removed. The mount is also described in DE2,811,812C 2.

For example, the strip may be a standardized cable termination having twelve terminals, which may be configured so as to form a two-core cable in each housing 100. It can only be enlarged by further use of the termination in a new housing. Further sealing of the wiring in the predetermined space of the cable termination forces miniaturization of the components used at the expense of the active area of each connecting slot over the wiring area, thereby deteriorating the working conditions for the assembler and adversely affecting the clarity of the wiring.

Using well-known telecommunication and data technology components, it would be difficult to obtain a depiction of the area of authority between the network operator and the user, which is becoming increasingly important and necessary.

DE-G9400303.3 describes a terminal assembly in which two rows of terminal strips are arranged at an angle of 90 degrees to each other, wherein the termination strips allow the use of insulation-piercing terminal technology, which avoids the use of soldering and stripping, and which can be used without screws, for use in data and communication technology, which can be used in a small space in standard connection sockets.

The disadvantage is that only the termination cannot be completed, which does not enable isolation, switching operations, and detection and further functions.

The object of the invention is to develop a generic termination strip, spacer strip and connection strip with the aid of very different circuits, so that protection and measurement tasks in telecommunications and data technology are ensured in a very small space with increased wiring density, reliability and with high convenience and clarity for the operator, which is necessary to ensure a reliable separation between the network operator and the user's administrative area.

The object of the invention is achieved by a termination strip, a spacer strip or a connection strip for telecommunications and data technology, comprising two insulators with connection elements and having fixing elements arranged on one insulator for locking on a holding device, wherein:

the two insulators are arranged at an angle to one another, the connecting elements are formed on the two planes and are connected to the insulators introduced into the two planes, so that two rows of terminal strips are formed which are at an angle to one another, and, furthermore, further fixing elements for locking on the holding device are provided on this insulator.

According to the invention, preferably a 90-degree angle is formed between the two termination strips, preferably together with angled insulation-piercing terminal connection elements formed continuously in two planes, whereby a universal strip for telecommunications and data technology can be produced, by means of which termination, isolation and connection tasks are made possible, and also detection, measurement, protection and uninterrupted switching can be made possible. The connection and the corresponding functional elements, such as overvoltage protection plugs or the like, which can be inserted into the two-part insulating body, can be exchanged as required.

The protection of the individual strips can be ensured by inserting some kind of device or the protection of the individual dual cores can be achieved.

A considerable reduction in the bar size can be achieved, while the wiring boards are also becoming larger and clearer, so that the wiring density can be increased by 33%, while, in a standardized cable connection, a usable area is obtained in which each connection slot in the wiring area is actually increased by 40% 6.

When the strip is in the final position, the wiring side is directed towards the assembler, which makes it possible for the strip to be routed in a convenient, reliable and clearly visible manner.

The arrangement of the strips on two planes can be used to prevent the operation of wiring on the core side of the cable at the bottom by suitable measures, such as by means of a frame that can be lead-sealed.

The routing of the strips on two planes may further allow for separation of the hosting area, i.e., the network operator side (cable core side on the bottom) and the subscriber side (patch panel on the top).

The mounting frame, equipped with two rows of locking rows, provided with locking openings on the side surfaces such that a smooth upper edge is maintained, which eliminates any risk of injury to the assembler, ensures a convenient, reliable and clear wiring in the first locking position, and a safe final position, i.e. the second locking position, which is difficult to operate and which can only be released using a wiring tool.

The rear side of the mounting frame has an elongated hole which enables a continuously variable adjustment of the cable strands and/or the plug by just loosening the retaining device so that a number of cable strands can pass alternately over the rear wall of the mounting frame.

Further embodiments of the invention seek to secure the strip to the profile rail or to secure the strip by means of flanges.

The invention will be described in more detail below with reference to embodiments of termination strips, spacer strips and connector strips shown in the accompanying drawings, in which:

fig. 1 shows a front view of a bar made of an insulator divided into two parts (upper and lower);

fig. 2 shows a rear view of the strip according to fig. 1;

fig. 11 shows a side view of the mounting bracket according to fig. 10.

Termination, isolation and connection strips are most suitable for connecting plastic insulated cable cores and insulated conductors, for example for termination in order to form cable connections in telecommunications local area cable networks.

The termination may, for example, comprise ten cables each having ten twinax cables, a mounting bracket 9 and a sign holder with a plate (not shown) which may be used as an adapter to correct the cabling on the core side of the cables.

The structural design of the strip as claimed according to the invention allows to reduce the size of the terminated grid in such a way that the existing four terminals can be inserted into the grooves of the cable connection instead of three terminals as of today. The storage density of the connections is increased by 33%, the definition is greatly improved and at the same time a larger space is obtained for the switchboard.

The area available for assembly in the power distribution area is actually increased by 40% in each connection slot.

Thus, the strip can be routed on two planes, so that the cable core side is at the bottom, while the switchboard side is rotated 90 degrees, which points upwards towards the assembler, and the ability to handle the cable core side (network operator area) is reduced by appropriate measures, for example by means of lead-sealable frames. The separation of the operator side from the user side of the network may separate the hosting area.

The structure of the strip can be seen from the illustrations in fig. 1-5. The insulator of the strip may be divided into two parts, which correspond to fig. 1-5, comprising an upper part 3 and a lower part 4. Upper part 3 and lower part 4, once fitted with insulation piercing terminal contact elements 7, 8, can be interlocked at an angle of 90 ° by means of locking openings 10 provided on both sides of strip upper part 3 and locking hooks 37 provided on both sides of strip lower part 4 (fig. 6, 8).

The insulation formed by the upper part 3 and the lower part 4 (housing part) can have the same structure for the function of forming different strips (terminating, isolating or connecting strips). The function of the different strips can be achieved by assembling different insulation-piercing terminal connection elements according to fig. 6 and 8, and by assembling additional external devices or the like.

As shown in fig. 1, the termination strip 1 formed on the upper part 3 has a connection groove 11 and the termination strip 2 formed on the lower part 4 has a connection groove 12, which are at 90 degrees to each other, and the wiring is thus performed in each case.

The termination strip 1 forms a wiring side RS for connecting outgoing lines on the subscriber side and the termination strip 2 forms a cable side KS for connecting incoming lines of a network operator.

Fig. 1 further shows known means 32, 33 for routing the cable cores, and locking elements 5 for locking the strip to a mounting frame 9 (fig. 10, 11) or a not shown structure. The strips may be arranged in rows as desired.

Simply locking the strips to the mounting 9 saves time consuming screw fixing work and also provides the ability to easily disengage individual strips from the mounting 9 by means of an unlocked tab which can be folded out of the wiring mechanism, if desired, which is not shown.

The strip can be locked in two positions on the mounting 9, as shown in the mounting 9 of fig. 10 and 11. In fig. 11, two rows of locking rows on the side walls 34 of the mounting frame 9 are shown. In order to facilitate the arrangement of the strip with the lead-in cable cores on the cable side KS, the strip is initially moved into its wiring position I (fig. 11), whereby it is locked by the locking element 6 into the locking opening 18 of the locking row 16 (fig. 2). Thereafter, the strip can be removed and locked in the final position II by rotating it 90 degrees relative to the locking elements 5 (fig. 1-4) locked in the locking openings 19 of the locking row 17 (fig. 11). The strip locked in the final position can be released as long as the locking is opened by using the opening piece, while the strip locked in the wiring position I can be released without any help. This makes it possible to clearly reach the wiring board, which is significantly larger than the prior art, facing the assembler, thus ensuring reliable and convenient wiring.

The locking openings 18, 19 provided in the side walls 34 of the mounting frame 9 have the advantage that the edges 35 of the side walls 34 are relatively smooth, which does not cause any risk of damage when fitting the strip.

As shown in fig. 10, the mounting bracket 9 has elongated holes 21 which allow for an infinitely variable adjustment of the cable strands or plugs, which prevents the cable strands of the cross-wires from being completely loosely held on the rear wall of the mounting bracket 9.

Fig. 4 shows a plan view of the bar facing the assembler when it is locked in the final position II of the mounting frame 9. The connection slots 11 and 13 face the fitter on the distribution board side RS, relative to which the connection slot 12 can be turned 90 degrees, which is on the cable side KS.

The strips can be designed as isolating strips or connecting strips according to the cross section shown in fig. 5, whereby isolating connecting elements 7 can be fitted.

The isolating connection element 7 according to fig. 5 and 6 is formed by a U-shaped insulation-piercing terminal connection contact 24 with an option contact 25 and an L-shaped insulation-piercing terminal connection contact 26 with an option contact 27. The two selection contacts 25 and 27 form a function selection connection 28 in the plane of the wiring side RS, through which any desired function selection element 15, not shown, can be inserted in order to perform a desired function, such as overvoltage protection. The isolation point 14 can also be designed as a connection point which is angled 36 on the selective contact arm 25, the angle of which can be omitted, and the contact arm 25 continues in a straight line.

The subscriber's drop cable core may be connected to insulation-piercing terminal connection contact 24 and the network operator's drop cable core may be connected to insulation-piercing connection contact 26, which may be rotated 90 degrees relative to connection contact 24.

Fig. 6 shows a plan view of the insulation-piercing terminal connection element 7 (isolated contact).

Fig. 7 shows a cross-sectional view of a strip configured with insulation-piercing terminations that can be connected to contacts 8 to form a termination strip.

The insulation-piercing terminal connection strip 8 is integrally formed of two insulation-piercing terminal connection contacts 29, 30 arranged at 90 degrees to each other, and a function selector 31.

The function selector 31 and the insulation-piercing terminal connection contact 29 can be accessed from the wiring side RS, while the insulation-piercing terminal connection contact 30 can be arranged from the cable side KS.

Fig. 8 shows a plan view when insulation-piercing terminal connection contact 8 is used in the strip according to fig. 7. Insulation-piercing terminal connection contact 29 can thus be angled at 45 degrees with respect to function selector 31.

Fig. 9 is a sectional schematic view showing how the connecting element of the strap locked on the mounting frame 9 is formed substantially dust-proof and succinctly by locking the insertion slot 22 on the mounting frame 9 and by means of the dust cover 23.
