- the present invention relates to cabinets for housing electronic equipment. More particularly, the present invention relates to a cabinet for housing electronic equipment and a connection panel for cross-connecting the electronic equipment with various provider and/or subscriber lines, wherein the cabinet provides access to the connection panel, and access to the front and rear sides of the electronic equipment.
- connection panel (sometimes referred to as a feeder-distribution interface), within the cabinet, is used to connect subscriber lines to provider lines directly, or in parallel or serial, with terminals of certain electronic equipment also within the cabinet, such as surge protectors, switches, servers, etc.
- the electronic equipment is sensitive to temperature and humidity, so the cabinet's interior is environmentally controlled by employing a heat exchanger, dehumidifier, and/or air conditioner.
- the electronic equipment needs to be accessible only on its front side. In other words, a service technician only needs to access a front side of the various components of the electronic equipment in order to make routine maintenance checks and to modify certain parameters. No access to the rear side of the electronic equipment is typically needed.
- FIG. 1 shows a cabinet 11 , in accordance with the background art, having a first door 13 , which provides access to the front side of electronic equipment 15 housed within a first compartment 12 .
- the cabinet 11 also includes a second door 17 , which provides access to a connection panel 19 housed within a second compartment 14 .
- the first compartment 12 is separated from the second compartment 14 by a partitioning wall 16 . Therefore, the first compartment 12 can be climate controlled.
- FIG. 1 As can be seen in FIG. 1 , no access can be gained to the backsides of the electronic equipment 15 . It would be necessary to remove the electronic equipment 15 to access the backsides of the electronic equipment 15 . Removing the electronic equipment 15 is time consuming and can necessitate disconnections of cables between the electronic equipment 15 and the connection panel 19 . Moreover, the design of FIG. 1 includes a “dead space” 21 , which is unusable. Hence, the cabinet 11 is not compact.
- FIG. 2 illustrates a modified cabinet design 31 .
- the cabinet design of FIG. 2 is similar to the cabinet design of FIG. 1 , however the electronic equipment 33 is located on a swing out rack 35 .

- the cabinet 31 of FIG. 2 still includes the dead space 21 . Further, in order to permit the electronic equipment 33 to clear the partitioning wall 16 , the cabinet 31 requires additional dead space 18 . Hence, the cabinet 31 must be made wider than the cabinet 11 of FIG. 1 , and the compact nature of the cabinet 31 is made worse. It should also be noted that the swing out rack 35 must be robust in construction and must be accommodated within the cabinet 31 . Thus again, there is an increase in the size and weight of the cabinet 31 . Further, there is an increase in the overall cost of the cabinet 31 , associated with the cost of the additional swing out rack 35 .
- FIG. 3 illustrates another cabinet 41 in accordance with the background art.
- the cabinet 41 includes a third door 43 .
- the third door 43 allows access to the backside of the electronic equipment 45 within the cabinet 41 .
- the cabinet 41 still includes the dead space 21 . Further, the sweep of the third door 43 on a third side of the cabinet 41 limits the area at which the cabinet 41 can be installed. Now, the cabinet 41 must be sufficiently spaced from adjacent cabinets, buildings, trees, etc. on three sides, as opposed to two sides, with regard to the cabinets 11 and 31 of FIGS. 1 and 2 .
- FIG. 4 illustrates another cabinet 51 in accordance with the background art.

- the additional equipment 63 or connection panel can also be supported on another swing out rack 61 .
- the second door 55 provides access to splices, a load center, or environmental control equipment 67 .
- the sweep of a third door on a third side of the cabinet 51 limits the area at which the cabinet 51 can be installed.
- the cabinet 51 allows access to the rear sides of the electronic equipment 59 and 63 , there is again the cost and space associated with the one or two swing out racks 61 .
- the swing out racks 61 require that a clearance space 65 be provided within the cabinet 51 , so that the electronic equipment 59 and/or 63 can pivot out to the cabinet 51 .
- the compact nature of the cabinet 51 is adversely affected.
- FIG. 5 illustrates another cabinet 71 in accordance with the background art.
- the cabinet 71 includes first, second, third and fourth doors 73 , 75 , 77 , 79 .
- the first and second doors 73 , 75 allow access to the front side and rear sides of the electronic equipment 81 and 83 .
- the rear sides of the electronic equipment 81 and 83 are accessible when the electronic equipment 81 and 83 are swung out on swing out racks 85 and 87 .
- the third and fourth doors 77 and 79 provide access to a connection panel 88 .
- the cabinet 71 allows access to the rear sides of the electronic equipment 81 and 83 , there is again the cost and space associated with the two swing out racks 85 and 87 . Moreover, the swing out racks 85 and 87 require that clearance spaces 84 and 86 be provided within the cabinet 71 , so that the electronic equipment 81 and 83 can pivot out of the cabinet 71 . Thus, the compact nature of the cabinet 71 is adversely affected.

Abstract
Description
- 1. Field of the Invention
- The present invention relates to cabinets for housing electronic equipment. More particularly, the present invention relates to a cabinet for housing electronic equipment and a connection panel for cross-connecting the electronic equipment with various provider and/or subscriber lines, wherein the cabinet provides access to the connection panel, and access to the front and rear sides of the electronic equipment.
- 2. Description of the Related Art
- Outdoor cabinets that house electronic equipment and connection panels are generally known in the art. The connection panel (sometimes referred to as a feeder-distribution interface), within the cabinet, is used to connect subscriber lines to provider lines directly, or in parallel or serial, with terminals of certain electronic equipment also within the cabinet, such as surge protectors, switches, servers, etc. Often, the electronic equipment is sensitive to temperature and humidity, so the cabinet's interior is environmentally controlled by employing a heat exchanger, dehumidifier, and/or air conditioner.
- In some cabinets in use today, the electronic equipment needs to be accessible only on its front side. In other words, a service technician only needs to access a front side of the various components of the electronic equipment in order to make routine maintenance checks and to modify certain parameters. No access to the rear side of the electronic equipment is typically needed.

FIG. 1 shows acabinet 11, in accordance with the background art, having afirst door 13, which provides access to the front side ofelectronic equipment 15 housed within afirst compartment 12. Thecabinet 11 also includes asecond door 17, which provides access to aconnection panel 19 housed within asecond compartment 14. Thefirst compartment 12 is separated from thesecond compartment 14 by a partitioningwall 16. Therefore, thefirst compartment 12 can be climate controlled. - As can be seen in
FIG. 1 , no access can be gained to the backsides of theelectronic equipment 15. It would be necessary to remove theelectronic equipment 15 to access the backsides of theelectronic equipment 15. Removing theelectronic equipment 15 is time consuming and can necessitate disconnections of cables between theelectronic equipment 15 and theconnection panel 19. Moreover, the design ofFIG. 1 includes a “dead space” 21, which is unusable. Hence, thecabinet 11 is not compact. - Some of today's newer equipment requires occasional access to the rear panels of the electronic equipment—typically to access cable connectors or to adjust switches located on the backsides of the electronic equipment. Moreover, today's electronic equipment can accommodate more users and connections, hence larger connection panels are associated with the electronic equipment. To address the need for rear access to the electronic equipment, one solution, in accordance with the background art, is to modify the cabinet design.
-
FIG. 2 illustrates a modifiedcabinet design 31. The cabinet design ofFIG. 2 is similar to the cabinet design ofFIG. 1 , however theelectronic equipment 33 is located on a swing outrack 35. If the technician opens thefirst door 32, access can be gained to the front sides of theelectronic equipment 33. If the technician, swings theelectronic equipment 33 out of thecabinet 31, using the swing outrack 35, access can be gained to the backsides of theelectronic equipment 33. - It can be seen that the
cabinet 31 ofFIG. 2 still includes thedead space 21. Further, in order to permit theelectronic equipment 33 to clear the partitioningwall 16, thecabinet 31 requires additionaldead space 18. Hence, thecabinet 31 must be made wider than thecabinet 11 ofFIG. 1 , and the compact nature of thecabinet 31 is made worse. It should also be noted that the swing outrack 35 must be robust in construction and must be accommodated within thecabinet 31. Thus again, there is an increase in the size and weight of thecabinet 31. Further, there is an increase in the overall cost of thecabinet 31, associated with the cost of the additional swing outrack 35. -
FIG. 3 illustrates anothercabinet 41 in accordance with the background art. Thecabinet 41 includes athird door 43. Thethird door 43 allows access to the backside of theelectronic equipment 45 within thecabinet 41. - As can be seen in
FIG. 3 , thecabinet 41 still includes thedead space 21. Further, the sweep of thethird door 43 on a third side of thecabinet 41 limits the area at which thecabinet 41 can be installed. Now, thecabinet 41 must be sufficiently spaced from adjacent cabinets, buildings, trees, etc. on three sides, as opposed to two sides, with regard to thecabinets FIGS. 1 and 2 . -
FIG. 4 illustrates anothercabinet 51 in accordance with the background art. Like thecabinet 41 ofFIG. 3 , thecabinet 51 includes first, second andthird doors first door 53 allows access to the front sides and rear sides of the electronic equipment 59. The rear sides are accessible when the electronic equipment 59 is swung out on a swing outrack 61, as described in relation toFIG. 2 . - The
dead space 21 within the cabinets ofFIGS. 1-3 has been replaced with additionalelectronic equipment 63 or a connection panel. The additionalelectronic equipment 63 or connection panel can reside on the base of thecabinet 51. Alternatively, theadditional equipment 63 or connection panel can also be supported on another swing outrack 61. Thesecond door 55 provides access to splices, a load center, orenvironmental control equipment 67. - As can be seen in
FIG. 4 , the sweep of a third door on a third side of thecabinet 51, again, limits the area at which thecabinet 51 can be installed. Although thecabinet 51 allows access to the rear sides of theelectronic equipment 59 and 63, there is again the cost and space associated with the one or two swing outracks 61. Moreover, the swing out racks 61 require that aclearance space 65 be provided within thecabinet 51, so that the electronic equipment 59 and/or 63 can pivot out to thecabinet 51. Thus, the compact nature of thecabinet 51 is adversely affected. -
FIG. 5 illustrates anothercabinet 71 in accordance with the background art. Thecabinet 71 includes first, second, third andfourth doors second doors electronic equipment electronic equipment electronic equipment racks fourth doors connection panel 88. - Although the
cabinet 71 allows access to the rear sides of theelectronic equipment racks clearance spaces cabinet 71, so that theelectronic equipment cabinet 71. Thus, the compact nature of thecabinet 71 is adversely affected. -
FIG. 6 illustrates another arrangement, in accordance with the background art, which includes first andsecond cabinets first cabinet 91 includes first, second, third andfourth doors second doors electronic equipment electronic equipment fourth doors second cabinet 92 includes fifth andsixth doors sixth doors connection panel 109. - As can be seen in
FIG. 6 , the arrangement requires the expense of twoseparate cabinets electronic equipment 101 and 103 (within the first cabinet 91) and the connection panel 109 (within the second cabinet 92) must pass outside of both of the first andsecond cabinets cabinets cabinets 91 and/or 92. Further, the sweep of the first throughsixth doors second cabinets - It is an object of the present invention to address one or more of the drawbacks associated with the cabinet designs of the background art.
- It is an object of the present invention to provide a cabinet design which allows access to a connection panel and the front and rear sides of electronic equipment housed within the cabinet, while maintaining a compact size for the cabinet.
- It is an object of the present invention to provide a cabinet design which allows access to a connection panel and the front and rear sides of electronic equipment housed within the cabinet, while reducing the overall cost of the cabinet.
- It is an object of the present invention to provide a cabinet design which allows access to a connection panel and the front and rear sides of electronic equipment housed within the cabinet, while providing greater flexibility in the cabinet's potential positioning, e.g. reducing the footprint required by the door sweeps to access the cabinet's contents.
- These and other objects are accomplished by a cabinet including a first compartment for housing electronic equipment, such as equipment used to provide telephone service and/or voice and data networking services. The front of the equipment housed in the first compartment is accessible via at least one door. The cabinet also includes a second compartment accessible by a second door, on an opposite side of the cabinet. The second compartment is for housing a connection panel, which allows subscriber lines to be connected to provider lines and/or terminals of the electronic equipment. A partitioning wall separates the first and second compartments and includes an access port communicating the first and second compartments. When the connection panel is moved, e.g. pivoted by use of a hinge, a service technician can gain access to the rear of the electronic equipment housed in the first compartment via the access port. An access panel can be used to close the access port so that the temperature and/or humidity of the first compartment can be regulated, as compared to the conditions in the second compartment and outside of the cabinet. The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

FIG. 9 is a cross sectional view similar toFIG. 8 , but illustrating the connection panel in a second position allowing access to a rear side of the electronic equipment; and -
FIG. 10 is a plan view illustrating an alternative embodiment of the cabinet inFIG. 7 , wherein double swinging doors are provided on each side of the cabinet. -
FIGS. 7 and 8 illustrate anoutdoor cabinet 111, in accordance with the present invention. Thecabinet 111 includes afirst compartment 113 for housingelectronic equipment 115. Thecabinet 111 also includes asecond compartment 117 for housing aconnection panel 119. - A
first door 121 provides access to thefirst compartment 113. Once thefirst door 121 is opened, a service technician can access the front side of theelectronic equipment 115 to perform maintenance operations or to set control parameters. - The
first door 121 can be attached to afirst side 112 of thecabinet 111 by a horizontal hinge. Alternatively, thefirst door 121 could be attached to thefirst side 112 of thecabinet 111 by a vertical hinge, or thefirst door 121 could be a removable door, e.g. a panel secured to thecabinet 111 by screws. - Typically, a
first lock 114 is attached to thefirst door 121. Thefirst lock 114 restricts access to thecabinet 111, so that only an authorized service technician can access thefirst compartment 113. - A
second door 123 provides access to thesecond compartment 117. Once thesecond door 123 is opened, a service technician can access the front side of theconnection panel 119 to cross connect cables via theconnection panel 119, or to splice wires directly. - The
second door 123 can be attached to asecond side 116 of thecabinet 111 by a horizontal hinge. Alternatively, thesecond door 123 could be attached to thesecond side 116 of thecabinet 111 by a vertical hinge, or thesecond door 123 could be a removable door, e.g. a panel secured to thecabinet 111 by screws. - Typically, a
second lock 118 is attached to thesecond door 123, so that only an authorized service technician can access thesecond compartment 117. A key or code for thesecond lock 118 may be different than a key or code for thefirst lock 114. By this arrangement, limited access to the first andsecond compartments cabinet 111 can be accomplished. For example, less-trained service technicians may be given access to only thesecond compartment 117. - As seen in
FIGS. 7 and 8 , athird compartment 125 is provided below the first andsecond compartments third compartment 125 may house power backup equipment, such asbatteries 127. Athird door 129 controls access to thethird compartment 125. - The
third door 129 can be attached to thefirst side 112 of thecabinet 111 by a horizontal hinge. Alternatively, thethird door 129 could be attached to thefirst side 112 of thecabinet 111 by a vertical hinge, or thethird door 129 could be a removable door, e.g. a panel secured to thecabinet 111 by screws. In another preferred embodiment, thethird door 129 is a drawer front, and thebatteries 127 are supported on a drawer base and may be withdrawn from thethird compartment 125 of thecabinet 111. Of course, thethird door 129 may optionally include a lock. - As illustrated in
FIG. 8 , thecabinet 111 may rest upon aslab 131 placed upon theground 133.Underground Cables 135 enter into anentrance area 137 from beneath thecabinet 111. Preferably, theentrance area 137 is located adjacent and beneath a lower edge of theconnection panel 119. - As illustrated in
FIG. 8 , apartitioning wall 141 separates thefirst compartment 113 from thesecond compartment 117. Thepartitioning wall 141 includes at least oneaccess port 143. Theaccess port 143 communicates the space within thefirst compartment 113 with the space within thesecond compartment 117. - An
access door 145 is employed to block theaccess port 143. Theaccess door 145 can be attached to thepartitioning wall 141 by a vertical or horizontal hinge. Alternatively, theaccess door 145 could be a removable door, e.g. a panel secured to thepartitioning wall 141 by screws. In a preferred embodiment, theaccess door 145 is pivotably connected to thepartitioning wall 141 by ahorizontal hinge 150. - As illustrated in
FIG. 9 , ahorizontal hinge 151 pivotably connects theconnection panel 119 to thecabinet 111. Hence, when thesecond door 123 is opened, a service technician can release alatch 158, and pivot a top edge of theconnection panel 119 away from thefirst compartment 113. - Once the
connection panel 119 is pivoted away from thefirst compartment 113, the service technician can manipulate theaccess door 145. For example, the service technician can release alatch 156, and pivot a top edge of theaccess door 145 away from thefirst compartment 113. - Once the
access door 145 has been moved away from theaccess port 143, as illustrated inFIG. 9 , the service technician has access to theback sides 161 of theelectronic equipment 115. Hence, the backsides of theequipment 115 are accessible via thesecond compartment 117, when theaccess door 145 is opened, and thefront sides 163 of theelectronic equipment 115 are accessible when thefirst door 121 is opened. - In a preferred embodiment, the
first door 121 and theaccess door 145 are capable of sealing with thefirst side 112 of thecabinet 111 and thepartitioning wall 141, respectively. By this arrangement, thefirst compartment 113 can be climate controlled, independent of the second andthird compartments electronic equipment 115 is often susceptible to temperature and humidity, whereas theconnection panel 119 and thebatteries 127 are not. Therefore, thefirst compartment 113 can be separately climate controlled, and the expense of climate controlling the second andthird compartments second compartment 117 does not create a climate shock to theelectronic equipment 115 located in thefirst compartment 113. - It would also be possible to have the
latch 156 being operable by a key or code which is different from the key or code that opens thesecond lock 118. By this arrangement, a service technician with access to theconnection panel 119, would not by necessity also have access to the rear sides of theelectronic equipment 115. - Instead of having a
latch 156 with a different coding or keying, it would also be possible to lock theaccess door 145 using alatch 160 which is only accessible from within thefirst compartment 113. Therefore, a service technician having access to the first compartment via thefirst door 121 could disengage thelatch 160 so that the rear sides of theelectronic equipment 115 could be accessed via theaccess port 143. -
FIG. 9 also illustrates asensor 170 attached to thepartitioning wall 141 and located adjacent to theaccess door 145. Thesensor 170 may be of any known design, such as a reed switch, which senses the presence of a metal strip attached to the edge of theaccess door 145. Thesensor 170 can be used to activate an alarm when theaccess door 145 is opened or to create a log of the event in a memory.Such sensors 170 may optional be included in combination with the first andsecond doors connection panel 119, to sense movement of these elements. -
FIG. 10 illustrates a modifiedcabinet 211, in accordance with the present invention. The modifiedcabinet 211 has thefirst door 121 replaced by twofirst doors 121 a and 121 b. Further, thesecond door 123 is replaced by twosecond doors electronic equipment 115 can include a first stack ofelectronic equipment 115 a and a second stack ofelectronic equipment 115 b. In all other regards, the modifiedcabinet 211 can be constructed in a same or similar manner, as discussed in relation toFIGS. 7-9 . - Although the drawings illustrate a
single connection panel 119, it should be appreciated that two or moreseparate connection panels 119 could be included within thesecond compartment 117. Under such circumstances, at least one of theconnection panels 119 would be moveably mounted in thesecond compartment 117, to provide access to one ormore access ports 143 located behind it. Further, it would also be possible that several or all of theconnection panels 119 could be moveable to revealseveral access ports 143 located behind them. - Although
horizontal hinges access door 145 andconnection panel 119, it should be appreciated such hinges may be vertical hinges or even replaced with other hardware, such as a four bar linkage with or without spring/cylinder movement assistance to enable movement of theaccess door 145 and theconnection panel 119. - In the drawings, the sides of the
cabinets - As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalence of such meets and bounds are therefore intended to be embraced by the appended claims.
