DISTRIBUTING FRAME BACKGROUND OF THE INVENTION A distributing frameis described in Belgian Pat. No. 708 844 (O. WUYTS et al. l3). Therein the first separating means consist of a plurality of horizontal jumper supports which are arranged in horizontal planes defining lower and upper subsections, the second separating means consist of vertical bars'carrying these horizontal jumper supports arranged in a similar vertical plane which 'subdivides the jumpering section in identical front and rear subsections. However, when two of these distribution frames are arranged back to back, i.e. with their rear subsections adjacent each other, those jumper wires which are arranged in the rear subsections are not easily accessible.

SUMMARY OF THE INVENTION An object of this invention is to provide a distributing frame wherein the larger part of the jumper wires are accessible after they have been arranged on the horizontal jumper supports.

According to the present invention this is achieved by making one of the 2 second subsections much larger than the other of the second subsections.

The inventive distributing frame therefore provides a maximum front subsection so that most of the jumper wires are easily accessible. This distributing frame is also particularly suitable for being used in a back-toback arrangement with a similar distributing frame.

Another characteristic of the inventive distributing frame is that third separating means are mounted in the other second subsection to provide therein one or more first jumper wire guide channels each associated with a distinct one of said first subsections and each adapted for guiding jumper wires from the first groups of terminals into the associated first subsection, said first guide channels being arranged in said second direction.

Another" characteristic of the inventive distributing frame is that fourth separating means are mounted in the second subsection to subdivide it in second jumper wire guide channels associated with particular members of the first subsections to guide jumper wires from said first subsections to said second groups of terminals, said second guide channels being arranged in the second direction.

Hence, each jumper wire interconnecting terminals of a first group and a second group is arranged successively in a first guide channel, a first subsection and a second guide channel. In this way the chance of making errors is reduced since the jumper wires do not interfere with each other.

Another advantage of the inventive distributing frame comprises a first apertured means mounted in a free section provided between the first groups of terminals and the first separating means, the apertures of each of said first apertured means being associated with distinct ones of said second subsections.

A further advantage of the inventive distributing frame is that a second apertured means is mounted' in a free section provided between the second guide channels and each of the second groups, the apertures of each of said second apertured means being associated with distinct ones of said second guide channels.

The use of these apertured means or so-called fanning strips further aids to prevent errors.

This invention therefore comprises a distributing frame for a telecommunication exchange which includes a plurality of first groups of terminals. a plurality of second groups of terminals, and jumper wires used to interconnect tenninals of said first and second groups. At least one auxiliary first group of terminals is associated with the plurality of first groups of terminals, and at least one auxiliary second group of terminals is associated with the plurality of second groups of terminals, and jumper wires are connected between terminals of the first group and the associated auxiliary first group. and between terminals of the second group and the associated auxiliary second group. Further electric connections are also provided between said first and second auxiliary groups of terminals.

One embodiment of the inventive distributing frame for a telecommunication exchange includes a plurality of line side panels and a plurality of exchange side panels separated by a jumpering section, above the first and below the second panels, the jumpering section houses jumper wires for interconnecting terminals of the line side panels and exchange side panels. The jumpering section is subdivided into a rear subsection and a front subsection, wherein the front subsection is much larger than the rear subsection, by a plurality of vertical uprights arranged in the same vertical plane and carrying a plurality of hoiizontal jumper supports which are arranged in lower and upper horizontal planes defining a lower and-an upper subsection which are arranged in vertical direction. The rear subsection constitutes a single first guide channel, whilst the front subsection is subdivided in both a rear and a first guide channel which are arranged in the same horizontal direction as the front and rear subsections. In the jumpering section the jumper wires connected to terminals of an odd numbered pair of line side panels are led successively through an associated lower fanning strip directly in the lower subsection, in the rear guide channel, and finally through the middle aperture of an upper fanning strip to an exchange side panel. The jumper wires connected to terminals of an even numbered pair of line side panels are led successively through an associated lower fanning strip, in the first guide channel, in the upper subsection, in the front guide channel and finally through the front aperture of an upper fanning strip to an exchange side'panel.

The above mentioned and other objects and features of the invention will become more apparent and the invention itself will be best understood by referring to the following description. of an embodiment taken in conjunction with the accompanying drawing wherein:

BRIEF DESCRIPTION. OF THE DRAWINGS FIG. 1 is a perspective view of a distributing frame according to the present invention;

FIG. 2 is an enlarged view of part of FIG. 1 after it has been partly equipped;-

FIG. 3 is a schematic view of a distributing frame according to the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 show the main distributing frame for a telecommunication switching system. Only part of the elements shown in FIG. 2 is represented in FIG. 1. The distributing frame as shown in FIGS. 1 and 2 constitute two sub frames 1 and 2 which are mounted back to back. As these two sub frames are identical only one of 3 them, i.e., sub frame 1, is described in detail hereinafter.

The sub frame 1 comprises three functional parts arranged one above the other: a lower or line side part 3, a middle or jumpering section 4 and an upper or exchange side part 5.

The line side part 3 includes a plurality of pairs of line side panels, such as 6, 7 and 8, 9 arranged in a row. Each of these pairs of panels carries a first group of line side terminals which are perpendicular to the plane of the panel and extend at both sides thereof. For instance, line side panel 7 carries the line side terminals schematically represented by 10. Line cables (not shown) are led through respective cable clamps, such as 11, provided at the bottom of the sub frame and are connected to the line side terminals e.g. by means of wrapped connections.

The exchange side. part includes a plurality of exchange side panels, such as 12, 13, arranged in a row.

Each of these panels carries a plurality of line-controlling keys and a second group of exchange side terminals which are strapped (not shown) to these keys and which extend at both sides of the panel. For instance, panel 13 carries the line-controlling keys and the exchange side terminals schematically representedby l4 and 15 respectively. Exchange cables (not shown) are led through respective cable clamps, such as 16, provided at the upper side of the sub frame and through holes 17 of a respective fanning strip such as 18, and are connected to the exchange side terminals e.g. by means of wrapped connections.

The jumpering section 4 houses jumper wires interconnecting line and exchange side terminals. At its lower and-upper sides the jumpering space 4 is delimited by a pair of longitudinally extending beams 19, and 21, 22 respectively.- The beams of each of these pairs are united by a plurality of horizontally mounted lower and upper transverse rods which are perpendicular-to these beams. For instance, the lower beams 19 and 20 are united by the lower transverse rods, such as 23, 24, and 26, whilst the upper beams 21 and 22 are united by the upper transverse rods, such as 27, 28, 29 and 30. The adjacent pairs of lower and upper transverse rods are united by vertical uprights each carrying a pair of intermediate horizontal transverse rods or jumper supports which are parallel to the lower and upper transverse rods. For instance, the pairs of lower and upper transverse rods 23, 27; 24, 28; 25, 29; and 26, 30 are united by the vertical uprights 31, 32, 33 and 34 respectively, these rods carrying the pairs of horizontal jumper supports 35, 36; 37, 38; 39, 40; and 41, 42 respectively. Hereby the lower or jumper supports 37, 39 and 41 are located in a first horizontal plane or level, whilst the upper or jumper supports 36, 38,

and 42 are located in a second horizontal plane or level. The set of vertical uprights 31 to 34 are located in a same vertical plane. The vertical uprights are further united in pairs by horizontal longitudinal rods which are perpendicular to the transverse rods. For instance, the vertical uprights of the pairs 31, 32 and 33, 34 are united by the horizontal longitudinal rods 43 and 44 respectively. Finally, adjacent upper transverse rods and upper jumper supports are united by vertical uprights located in a same vertical plane parallel to that wherein the vertical uprights 31 to 34 are located. For instance, the transverse rods of the pairs 27, 36; 28, 38; 29, 40 and 30, 42 are united by the vertical uprights 45, 46, 47 and 48 respectively.

At its lower and upper sides the jumpering section 4 further comprises four-apertures .and three-apertures fanning strips which are transversely mounted between the longitudinal beams 19, 20 and 21, 22 respectively and in front of a longitudinal rod. For instance, lower and upper fanning strips 49, 51 and 50, 52 are mounted adjacent the longitudinal rods 43 and 44 respectively. The lower fanning strips 49 and 50 have the four apertures 53 to 56 and 57 to 60 respectively, whilst the upper fanning strips 51 and 52 have the three apertures 61 to '63 and 64 to 66 respectively.

The lower fanning strips are each associated with a pair of line side panels, while the upper fanning strips are each associated with an exchange side panel. Each of the two rear apertures of each lower fanning strip is used to guide jumper wires connected to terminals of a distinct one of the line side panels of the associated pair. For instance, the rear apertures 53, 54 and 57, 58 of the lower fanning strips 49 and 50 are used to guide jumper wires connected to terminals of the line side panels 6, 7, 8 and 9respectively. The front apertures of the lower fanning strips, such as 55, 56, 59, 60 of the fanning strips 49 and 50 are not used. The apertures of the upper fanning strips are used to guide jumper wires connected to terminals of the associated exchange side panel. For instance, the apertures of the upper fanning strips 51 and 52'are used to guide jumper wires connected to terminals of the exchange side panels 12 and 13 respectively. More particularly, the middle and front apertures, such as 61, 64 and 62, 65 of the upper fanning strips such as 51 and 52 are used to guide jumper wires connected to terminals of the first and second pairs of line side panels 6, 7 and 8, 9 respectively. Likewise, the jumper wires connected to the other odd numbered and other even numbered pairs of line side panels (not shown) are led through the middle and front apertures of the upper fanning strip associated with the exchange side panel to which they are connected respectively. The rear apertures such as 63, 66 of the upper fanning strips, such as 51, 52 are used to guide jumper wires connected to terminals of line side groups forming part of the sub frame 2.

From the above it follows that the jumpering section 4 may be considered as being subdivided in two first subsections arranged in vertical direction and in two second subsections arranged in horizontal direction: a lower first subsection located between the jumper supports 35, 37, 39, 41 and 36, 38, 40, 42 and an upper first subsection located above the jumper supports 36, 38, 40, 42; a rear and a front second subsection located behind and in front of the vertical uprights 31 to 34 respectively, the front subsection being much larger than the rear one.

The longitudinal rods 43, 44 may be considered as defining in the rear second subsection a single first jumper wire guide channel, but obviously more such longitudinal rods could be provided to define in the rear second subsection aplurality of such first jumper wire guide channels arranged in horizontal direction.

The front second subsection may be considered as being subdivided in:

a rear second jumper wire guide channel located between the;ve;rti cal uprights 31 to 34 and 45 to 48; a front second jumper wire guide channel'located in front of thejve'rtical uprights 45 to 48, these second guide channels extending in horizontal direction.

It should be noted that the first guide channel is associated with the upper first subsection, while the rear and front second guide channels are associated with the lower and upper first-subsections respectively: More overfthe middle and front apertures of theilippr fang. ning strips are associated with -the rear and front 'second g ide'cha'nnels.

FIG. 2 shows how a pluralityfofjumper'wire biindles channel defined between thevertical uprights 31 to 34 and the vertical uprights 45 "to" 48fand finally through the middle aperture 61 of th'eupper fanning strip 51 to the exchange side panel 12; 1 I jum'per wire bundles 69 and 70 which are'connected to terminals of the respective panels 6 and 70f the first pair of line side panels 6, 7 are led successively through the respective apertures 53 and 54 "of' the lower fanning strip 49 onto the jumper supports 37 and of the lower first subsection defined between .the lower jumper supports 35, 37, 39,41 and the upper jumper supports 36, 38, 40, 42" into the rear second guide channel defined between the vertical uprights 31 to 34' and the vertical uprights 45 to 48 and finally through themiddle aperture 64 of the upper fanning strip '52to the exchange side panel 13; jumper wire bundle 71 which is'connected to terminals of the panel 8 of the second pair of line side panels 8,

9 is led successively through the respective aperture 57 of the lower fanning strip 50 into the first guide channel located behind the longitudinal rods 43 and 44, then on the upper jumper supports 40 and 38 of the upper first subsection delimited by the upper jumper supports 36, 38, 40, 42 and the upper transverse rods 27 to 48, then into the front second guide channel located in front of the vertical uprights 45 to 48, and finally through the front aperture 62 of the:

upper fanning strip 51 to the exchange side panel 12;

jumper wire bundle 72 which is connected to terminals of the panel 8 of the second pair line side panels 8, 9 is led successively through the respective aperture 57 of the lower fanning strip 50 into the first guide chan-' nel located behind the longitudinal rod 44, then on the upper jumper support 42 of the upper first subspace delimited by the upper jumper supports 36, 38, 40, 42 and transverse rods 27 to 30; etc. (not shown);

jumperwire bundle 73 which is connected to terminals of the panel 9 of the second pair of line side panels 8, 9 is led successively through the respective aperture 58 of the lower fanning strip 50 into the first guide channel located behind the longitudinal rod 44, then in the first second guide channel located in front of the vertical uprights 45 to 48, and finally through the front aperture 65 of the upper fanning strip 52 to the exchange side panel 13;

jumper wire bundle 74 which is connected toterminals of a line side panel belonging to the sub frame 2 is led through the aperture 63 of the upper fanning strip to the exchange side panel 12.

It is clear that the above described subdivision of the jumpering space 4 in first and second subsections and in first and second guide channels permits the arrange'-" odd and even numbered'pairs of-line,

highlln this case:

onnected to terminals of the 'de-n lsfa ranged tin a row are led in"th'e l'owei an per first subsections I respectivelyl i.e. i n"a ,cyelicj it clear that the j umper wiresare thus equally distributed over these I first subsections and' that this so reduces the chance "of making errorst- Since the jumper wire-s Sc v r c. 3 wh'ferein the frames 1' and 2 with their. constituentparts 3, 4, 5 and 3 4-'a'nd 5 are schematically: represented, When the number of-lineside panels and exchaiige side panels arranged inthe-partsli, .3; and 4, 4' respectively are relatively high, obviouslyithe lengthtof the jumper wires arranged in th jjump erin g sections'4 and 4 becomes a'pair of auxiliary blocks of terminals75, 76;;77, 78 and I '75, 76'; 77, 78".is associated-to each of the ends of the line side parts 3 and 3' respectively; b v a pair of lower andzupper auxiliary; blocks of terminals 79, 80; 81,82 and 79'., 80", 81', 82, which are identical to'the abovementioned onesis associated to each of the ends of the exchange side parts 5 and, 5 respectively. f.

Hereby terminals of the-lower auxiliary blocks of terminals associated with-the exchangeside panelsof a sub frame are connected to terminals of-the-auxiliary blocks of terminals'associated with. the line side panels of the same sub frame via further electric connections,

e.g.: wire 83 connects terminals-of the auxiliary blocks and ofsub frame 1; v a 31 wire 84 connects terminals of the auxiliary blocks 77 and 78 of sub frame 1; wire 85 connects terminals of the auxiliary blocks 77 and 79' of sub frame 2; wire 86 connects terminals of the auxiliary blocks 76 and 80 of sub frame 2. The terminals of the upper auxiliary blocks of terminals associated with the exchange side panels of a sub frame are connected to terminals of the auxiliary blocks of terminals associated with the line side panels of the other'sub frame via further electric connections,

e.g.. wire 87 connects terminals of the blocks 77 and 81 of the sub frames 1 and 2 respectively; wire 88 connects terminals of the blocks 76 and 82' of the sub frames 1 and 2 respectively;

wire 89 connects terminals of the blocks 81 and 76' of the sub frames 1 and 2 respectively;

wire 90 connects terminals of the blocks 82 and 75' of the sub frames 1 and 2 respectively.

With this arrangement, the jumper wires connected to terminals of a line side panel, respectively exchange side panel, are arranged in the jumpering section in an analogous way as described above in relation with FIGS. 1 and 2, but instead of being connected to terminals of an adjacent exchange side panel, respectively line side panel, these jumper wires are connected to terminals of an adjacent auxiliary block of terminals. This arrangement obviously permits to use jumper wires having lengths much smaller than if one would directly interconnect terminals of line and exchange side panels by jumper wires in case the number of these panels is very high.

While the principles of the invention have been described above in connection with specific apparatus it is to be clearly understood that this description is made 7 only by way of example and not as a limitation on the scope of the invention.
