Abstract

The mounting frame is used as a subframe 1 for optical or electrical assemblies. Optical fibres are introduced onto horizontal trays located within the subframe. Further fibres can then be connected to these fibre ends by means of suitable plug connectors. The plug connectors are arranged on the side of the tray. The trays are suspended on guides 10, 11 which are attached to the inside of the side wall 3, 4 or to a comb structure 6. The comb structure allows a void 40 within the subframe in which connection to the plug connectors are made. <IMAGE>

Description

MOUNTING FRAME The present invention relates to a mounting frame for use as a subframe for optical or electrical assemblies.

Optical cables for communication of voice or data over large distances generally contain a large number of individual optical fibres, there being perhaps 160 fibres in a typical cable. In order to provide versatile means for coupling these fibres to each other and to the fibres of other cables, or to equipment, the cables are generally led into a frame in the form of a cabinet. The cabinet has two sets of fixing holes running down the front of each side wall of the cabinet, for the attachment of one or more intermediate frames or subframes ("panels") to the cabinet. Each of these subframes can hold a number of "trays" and is insertable into and removable from the main cabinet as a unit with the trays.

In the cabinet the cable is split into its constituent fibres, and these fibres are introduced into the trays with generally a considerable spare length of fibres coiled up and resting in each tray.

The ends of the fibres are attached to a number of adapters in the form of sockets. There may for instance be ten sockets, corresponding to ten fibres, mounted in a line on the tray. Further fibres can then be connected to these fibre ends by means of suitable plug connectors.

The line of adapters on the tray has in the past been arranged on the front edge of the tray, i.e.

facing the operator. In the case of optical networks this poses a safety hazard because if a plug is removed the light will leave the adapter unhindered and may strike the eye of the operator. While this may not be harmful if low-power laser systems are used it is still a nuisance; furthermore, in view of the tendency to use higher power lasers, particularly for voice transmission, it is desirable to avoid front-facing adapters altogether. Hence there has recently been a tendency to arrange the line of adapters on the side of the tray.

A consequence of the side-mounting of the adapters is that a gap must be provided between the adapters and the adjacent side wall of the frame, to allow room for the plugs and associated cables. This gap means that the corresponding side of the tray is not supported by the rail in the frame cabinet and must be supported in some other way. This could be done by placing horizontal bars across the whole width of the front of the frame; however, since the height of the trays is, for a standard data communications tray, only 1.75 inches (4.4cm), these bars make it impossible for the operator to insert his hand into the space between the adapters and the adjacent side wall of the frame, so that plugs cannot be inserted into or removed from the adapters while the tray is in place.

According to the invention there is provided a sub-frame for supporting trays of optical or electrical equipment in a cabinet-shaped main frame, the sub-frame comprising a first side wall member having means for horizontally guiding one side of the trays into and out of the cabinet when the sub-frame is installed therein, a second side wall member opposite the first side wall member, means for connecting the side wall members, and a comb-shaped structure fixed in the sub-frame parallel to, and in between, the side wall members and spaced from the first side wall member by the width of a tray, the tines of the comb being adapted to provide means for horizontally guiding the other side of the trays.

The comb structure provides support for the sides of the trays opposite the first side wall member, and provides a free space between these tray sides and the second side wall member of the sub-frame, making the adapters easily accessible without removing the trays from the sub-frame.

Advantageously the subframe is of a height corresponding to three trays, i.e. 13.3cm, since this is the smallest height into which a hand can easily be inserted to operate on the adapters. However, a height of four or six units could also be useful. In a standard 19-inch (48cm) data communications frame the internal width is 44cm, and the width of the trays is 31cm, leaving a width of 13cm for manual insertion.

The side walls may be held together by four elongate structural members extending horizontally between corresponding corners of the side walls, forming a box shape; this allows access to the trays from the rear for the introduction of cables and fibres.

In a similar fashion the side walls themselves need not be solid as long as they have the necessary rigidity to support the trays and maintain the shape of the sub-frame. Indeed, conceivably the first side wall member could itself include a comb-shaped structure spaced from the side of the sub-frame, leaving a certain amount of space on both sides of the trays.

The guide means provided by or on the tines of the comb may advantageously have a cross-section in the shape of a simplified capital G, the trays having a downwardly extending lip fitting into the G so that the tray rests securely in the G in operation.

The tines themselves can be made of low-friction plastics material or, advantageously, the comb may be formed by a comb-shaped sheet steel piece to the tines or arms of which the required number of plastics Gchannels may be attached. The G-channels may then be extruded members cut to the required length.

To prevent inadvertent removal of the tray by pulling it too far out of the cabinet a pin may be inserted transversely across the lower part of each Gchannel, and the lower edge of the lip of the tray may have corresponding cutouts so that in the fully inserted and extracted positions the tray, having slid over the pin, comes to rest in the correct position by engagement of the pin with the appropriate cutout.

For a better understanding of the invention, an embodiment will now be described with reference to the accompanying drawings, in which: Fig. 1 shows a perspective view of a subframe in accordance with the invention; Fig. 2 shows a G-channel member; Fig. 3 shows a tray for insertion into the subframe; and Fig. 4 shows a section through the edge of a tray resting in the G-channel.

Figure 1 shows a subframe 1 for insertion into a main frame or cabinet, in which it is held by virtue of fixing plates 5 by means of bolts passing through holes 5a. The subframe has horizontal structural members 41, 42, 43, 44 connecting the four corners of side walls 3 and 4, the fixing plates 5 protruding outwardly from the side walls for fixing to the cabinet. In a standard data communications cabinet of nominal width 19 inches (48cm) the distance between the side walls is 44cm. The two rear structural members 44 and 43 define a rear access space 2 through which the cables can be introduced.

A comb-shaped structure 6 is fixed to the structural members 41, 43 and 44 parallel to and at a spacing d from the left-hand side wall 3 in the Figure.

The comb 6 consists of a steel sheet 7 having a spine 8 and arms 9, a stiffening plate 8a being formed by bending the sheet at a right angle. The arms or tines 9 of the comb each have a channel 10 fixed to them, and there are corresponding runners or channels 11 on the side wall 3 so that a tray can slide on the channels for insertion into and removal from the subframe, and thus from the cabinet.

Fig. 2 shows a length of a suitable G-channel 10.

The cross-section has the shape generally of a capital G, with a longitudinally extending central recess 12 and a longitudinal aperture or mouth 13. In use the edge of the tray passes through the mouth 13, resting on the lip 14. A pin 15 is inserted across the end of the recess 12 for stopping the tray in its fully extracted position, as described in more detail with respect to Fig. 3.

A tray suitable for insertion in the subframe is shown in Fig. 3. A bundle of fibres (not shown) enters the tray 20 from the left in the Figure, and separated fibres are mounted in adapters 30 (see Fig. 4) which are then fitted in apertures 29. The base 21 of the tray is bent upwards at the front and rear to form front and rear walls 22, 23 and is bent downwards at the sides to form rails 24, 25. The rails are to be inserted into the mouth 13 of the G-channels, as described above. The lower edge of the rails 24, 25 has three cutouts 26, 27: the front cutout 26 of each rail engages with the corresponding pin 15 when the tray is fully inserted while one of the rear cutouts 27 engages with the same pin when the tray is pulled out for examination.The height of the longitudinal recess 12 with the pin 15 is such as to allow the tray to be lifted so that the rails 24, 25 can travel over the pins 15.

The tray 20 further has a side bracket 28 attached along one edge by means of rivets 31, as can best be seen from Fig. 4. Attachment of the bracket 28 is slightly inward of the side edge of the tray so as to allow space for the top of the G-channel 10 while the tray is in use by virtue of a double-right-anglç bend in the bracket near the riveted edge. The bracket then extends further horizontally for several centimetres so that it projects entirely beyond the comb structure, whereupon it is bent upwards to form a sidepiece 32.

The holes 29 (Fig. 3) for mounting the adapters 30 are formed in this sidepiece 32.

It will be seen that the bracket with the adapters projects well beyond the plane of the comb 6. The open front edge of the comb nevertheless allows insertion and removal of the trays with the adapters without hindrance by the comb structure.

When the assembled tray is mounted in the subframe the adapters 30 project into the space 40 (Fig. 1) at the side of the trays and are therefore freely accessible. Since the subframe 1 accommodates three trays there is sufficient space between bottom and top front structural members 41 and 42 for an operator to insert his hand into this side space 40, so that removal of individual trays of the subframe is not necessary for operations merely involving inserting and removing plugs from the adapters.

While Figure 1 shows only one comb-shaped structure 6, clearly the subframe 1 could have two such combs 6 spaced from the respective side walls of the subframe so as to provide a side space 40 on either side of the sets of trays.

Although the invention has particular application for optical couplers, it could be used for electrical equipment also.
