Description
2~9~6 ~AN8LS FOR CONTAINING TBLECOMMUNICATIONS BQUIPM~NT
This invention relates to panels for containing telecommunications equipment.
In certain electronic installations such as transmission installations, electrical current breaker interface panels are used to interconnect certain items of equipment. Such a panel comprises a rigid structure carrying within it interface equipment and wiring and the lo panel may be installed in a stacked position with other equipment. The panel is also provided with manually operable switches which are mounted upon a breaker carrier structure for access from the front of the panel when this is in a use position.
Conventionally, to connect a breaker to wiring within the panel, this needs to be performed from the front of the panel. It is necessary to move the breaker carrier structure to a forward position, possibly by it being hinged, so as to enable the breaker to be secured by screws to the rear of the support, the rear then being in an accessible position from the front of the panel.
The problem with this conventional arrangement is that the carrier structure in operating like a swinging door requires space for its swinging operation. Further, a large mass or ~nest~ of electrical wiring may be present within the panel and swinging the carrier structure between open and closed positions disturbs the positions of the individual wires in the Unestu while causing them to flex and pull around each other, thereby placing undue stress and strain upon the wiring which may eventually lead to failure after repeated opening and closing of the carrier structure.
Further to this, upon opening of the carrier structure for the replacement or insertion of one of the breakers, the large number of wires extending to the door from within the panel may prove to be extremely obstructive to any procedure required.
20~9~6 The present invention seeks to provide a panel for containing telecommunications equipment which will overcome or minimize the above problems.
Accordingly, the present invention provides a 5 panel for containing telecommunications equipment comprising boundary wall means including a front wall which is formed with a plurality of electrical current breaker receiving chambers each of which has a forwardly facing front opening for reception and removal of a corresponding electrical current breaker into the chamber, and holding means for each chamber for detachably retaining the breaker in an operative position within the chamber, each chamber also having a rear opening to allow for the breaker to be connected to wiring within the housing.
The holding means may be of any structure, such as a front retaining plate, suitable for detachably holding a breaker within each chamber. Advantageously, however, the holding means comprises a latch for retalning the breaker within the chamber and at least one seating surface for abutting engagement with the breaker.
As may be seen from the panel according to the invention, with the chamber arrangement the breakers may be received and removed into the chambers through the front of - the housing without it being necessary to open the panel so as to provide access for the breakers from the rear. Upon removal of the breakers, any electrical wiring connected to the breakers will be automatically drawn from the front of the chamber for access purposes to the wiring and breaker terminals. Other wiring within the panel is thus not unduly interfered with and such other wiring does not cause a hindrance to the insertion and removal of breakers.
It is preferable that chambers are disposed in a rectilinear row and a wall extends along one side of the row and partly defines its chamber. Latches of the holding means for the row of chambers are formed by individually resiliently flexible parts of this wall.
2 ~
It ls also preferable that the chambers are provided by a chamber defining structure which is detachably mounted upon the panel. Thus this structure may be separately formed, e.g., by an advantageous molding operation, before being added as a single element to the rest of the housing.
It ls also preferred that each chamber unoccupied by a breaker is occupied by an electrically inoperative individual chamber closure member and this closure member lo is detachably retained within the chamber by a respective holding means. In this arrangement, it is preferable that each chamber closure member is secured through the rear opening of the chamber to electrical wiring which is to be used for connection to a breaker later to be inserted into the chamber upon removal of the closure member. The closure member is removable through the front opening of its chamber so as to draw with it, through the front opening and for wiring access purposes, the electrical wiring connected to the closure member. It follows therefore that when using closure members and adding a further breaker into a previously unused chamber, the electrical wiring is made accessible from the front of the panel to enable the electrical connections to be made easily.
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:-Figure 1 is an isometric view of a breaker interface panel to be disposed between other panels of telecommunications equipment;
Figure 2 is an isometric view, to a larger scale than Figure 1, of a chamber defining structure which is to form part of the panel of Figure l;
Figure 3 is a cross-sectional view through the structure of Figure 2 and taken along line III-III in Figure 2 with an electrical current breaker and a chamber closure member disposed in respective chambers;
4 2~9~fi Figure 4 is a cross-sectional view through the structure taken along line IV-IV in Figure 3; and Figure 5 is a view similar to Figure 3 with the breaker and the closure member removed from the front of the structure.
In the embodiment as shown in Figure 1, a breaker interface panel 10, for electrical disposition between two other panels of telecommunications equipment, comprises two side walls 12 and 14 extending forwardly from a rear wall o 16 of the panel. Each of the side walls 12 and 14 may comprise a printed circuit board or have a printed circuit board attached to the inside surface of the wall. Within the panel, as is well known in the telecommunication art, are provided brackets, such as bracket 18, for holding 15 various items of telecommunications equipment such as inductors 20, and a backplane 22 spaced from the front of the panel and extending partly between the side walls 12 and 14. Forwardly of the backplane 22 is disposed a conventional structure 24 for the sliding reception of edge cards (not shown) to be received through an opening 26 at the front of the panel, the opening defined by a front panel border 28. Between an inner edge of the border 28 and a short front wall 30, extending slightly inwardly from the side 12, extends a chamber defining structure 32 for holding electrical current breakers for connection to wiring within the panel.
As is more clearly shown by Figures 2, 3 and 4, the structure 32 is horizontally elongate and is formed with two horizontal rectilinear rows of chambers 34 30 extending from side to side of the structure. The chambers are of vertically elongate rectangular shape from a front of the structure 32 and are disposed one above the other from one row to the other, being partly defined by vertical walls 36 and a horizontal central wall 38, each wall 36 and 38 partly defining a chamber on each side of it. Chamber definition is completed by two end walls 40 and two horizontal top and bottom walls 42 and 44, the end walls 40 2Q59~6 and the top and bottom walls 42 and 44 also providing the boundaries for the structure 32.
Each breaker 46, as is shown by a comparison of Figures 3 and 4, is rectangular in cross-section so that a 5 breaker when inserted into a respective chamber 34 has its longitudinal access extending vertically.
The panel 32 is provided with a holding means in ; respect of each chamber for holding a breaker 46 within the chamber. With respect to the upper rectilinear row of lo chambers, the holdin~ means for each chamber comprises a flexibly resilient latch which is provided by an individually resiliently flexible part or finger 48 of the wall 42. As may be seen, the fingers 48 lie in a row with slots 50 formed rearwardly from the front edge of the wall 15 42 at each side of each finger 48 allowing for individual resilient flexibility of the finger about a fixed base connected to the remainder of the wall 42. At a forward end of each finger, the latch is completed by a conventional short downward latch protruberance 52. The lower row of chambers 34 is similarly provided with latches of locking means by fingers 54 formed in the wall 44 in a fashion similar to the fingers 48. The fingers 54 have upward end latch protruberances 56.
The holding means for each of the chambers 34 also includes at least one seating surface for abutting engagement with the breaker when this is disposed within the chamber. As may be seen more clearly from Figure 4, in respect of èach chamber, each vertical wall 36 is formed at its rear edge with an upwardly extending flange 58 which extends partly across a rear opening 60 of the chamber so that the flanges 58 at the two sides of the chamber approach each other. An additional L-shaped flange 62 extends rearwardly of each flange 58 to terminate in an inward projection 64 of the L-shape. Forwardly facing surfaces 66 of the flange 58 provide seating surfaces for abutting engagement with rear facing surfaces of the breaker, as will be described. The inward projections are .,:
, ,- ~
6 2 ~ 6 spaced-apart a distance to contact side surfaces of the breaker as this moves into an operative position, as will be described, so as to assist in breaker location. The end walls 40 are similarly provided with flanges (not shown) 5 which cooperate with flanges 58 and 60 on the adjacent vertical wall 36 for providing seating and location surfaces for breakers when received in the end chambers of each of the rows.
AS may be seen from Figure 2, at the forward edges lo of the sides 40 of the structure 32, are provided two vertical end flanges 70 having screw holes 72 for screwing the structure 32 at its ends to the panel border 28 and to the short front wall 30 of the panel 10.
Initially, with the panel equipped with its 15 required telecommunications elements and having a unest~
wiring 74 extending as necessary between the elements and to the structure 32, any individual wires required for connection to individual breakers are passed through the respective chambers 34 by passing the wires through the rear opening 60 and out through the forwardly facing front opening 76. This operation together with the assembly of the breakers onto the panel is performed with the structure 32 assembled into the rest of the panel as shown in Figure 1. Any breaker 46 that is immediately required for use with the panel 10 (Figure 3) is then connected by its terminals 78 to its respective wiring 74 and the breaker is inserted into its chamber by sliding it between the walls of the chamber and passing it beyond its flexed latch finger 48 or 54 into the chamber. Upon the breaker . 30 reaching its operative position (Figure 4), two vertical rearwardly facing surfaces 80 at sides of the breaker contact the seating surfaces 66 while rear side surfaces 68 of the breaker are located between the free ends of the .: inward projections 64. In this position of the breaker, if the breaker is in a chamber of the top row, then its finger 48 resiliently descends to engage its latch protruberance 52 in front of the breaker to hold it in its operative 7 2 ~ s ~
position. Similarly if the breaker is in the lower row, then the latch protruberance 56 holds the breaker in position. In the assembled position, each breaker has a forward facing manually operable toggle 86 for breaker operation and this toggle is partly shrouded at its sides by two forwardly facing finger guards 88 extending forwardly from the respective walls 36 or 40. These finger guards 88 help to prevent inadvertent operation of adjacent breakers.
lo To enable the individual breakers to be removed for replacement or inspection or repair, it is a simple matter to resiliently deflect the appropriate latch finger 48 or 54 to enable the respective breaker to be removed forwardly from the front opening of its chamber. This is the position shown in Figure 5. AS may also be seen from this figure, upon removal of the respective breaker, the wiring 74 attached to it is drawn forwardly through the chamber 34 and out through the front opening 76 so that it may be removed from the terminals 78, if required, and easily attached to a replacement breaker. Thus access to the inside of the panel, such as by moving of the structure 32, is completely unnecessary and the nest of wires 74 within the panel is thus virtually undisturbed by removal of any particular breaker 46.
In addition, the embodiment also includes an electrically inoperative individual chamber closure member 90 which is provided to fill and close any particular chamber 34 which is at any time unoccupied by a breaker.
Each closure member serves a double purpose in that it closes off an unused chamber so as to prevent inadvertent access through the chamber to the inside of the panel such as could cause damage to equipment within that panel, and it also enables easy access to wiring 74 which will subsequently be required for connection to a breaker assembled into that chamber. To this latter end, each of the closure members is connected at a rear facing side to the appropriate wiring 74 and, for convenience, terminals 8 2Q~56 78 such as are normally used upon a breaker may also be used for this purpose. As may be seen in Figure 3, each closure member is retained in position by a latch finger 48 or 54 in a similar manner to the location of the breakers s 46 in the operative positions. Upon removal of any closure member 90, this is necessarily removed through the front opening 76 of its respective chamber thereby drawing the associated wires 74 with it so as to provide access to these wires for connection to a breaker to be assembled io into the chamber. Hence with the use of the closure member, while the wires 74 associated with that particular chamber are protected before assembly of a breaker into the chamber, nevertheless the wires are immediately accessible for assembly to the breaker. Thus access into the inside of the panel is not necessary for breaker assembly purposes.
