- the enclosure 10 of the present invention has a rugged, substantially weather resistant and weather-tight construction that makes it ideal for outdoor telecommunications applications.
- the enclosure 10 also has a relatively large volume that makes it particularly applicable to telecommunications applications involving splicing of large pair count cables. Such applications can involve thousands of copper wire splices.
- the enclosure 10 could also be used at locations in telecommunications systems having both copper wire and fiber optic equipment.
- the enclosure 10 of the present invention could be configured to accommodate from 1,800 to 3,600 copper splice pairs and/or passive fiber optic equipment.
- the enclosure 10 could also be used to house large cable television equipment such as splitters or amps and active electronics. For use in such applications, the enclosure 10 should have an internal volume of approximately 10 cubic feet or larger.
- the illustrated enclosure has a relatively simple construction including a base section 12 and a single-piece cover or dome 14 .
- both the base section 12 and dome 14 have a rectangular configuration.
- the base section 12 has a front wall 16 , a rear wall 18 and opposing lateral sidewalls 20 and is open at the top and bottom.
- the dome 14 has a front wall 22 , rear wall 24 , opposing lateral sidewalls 26 and a top wall 28 and is open at the bottom.
- the dome 14 nests in a telescoping fashion over the base section 12 with the open bottom of the dome 14 fitting over the open top of the base section 12 so as to define an interior space within the enclosure 10 .
- the top wall 28 of the dome 14 is pitched so as to prevent an accumulation of snow or water on top of the enclosure 10 .
- the single piece, solid wall construction of the dome 14 eliminates the joints or seams that result from the multi-piece construction of the upper portion of existing metal cabinets. As will be appreciated, this effectively eliminates the opportunity for water leakage into the interior of the enclosure 10 , thereby creating a “bell-jar” effect. Additionally, by eliminating the doors, the risk that a technician will not securely close the enclosure 10 is substantially reduced.
- An additional advantage of the single piece, solid dome 14 is that a technician has unrestricted 3600 access to the interior of the enclosure 10 when the dome is lifted off the base section 12 . As a result, it is much easier to install and maintain the equipment in the enclosure 10 as compared to having to work through a doorway on a conventional metal telecommunications cabinet.
- the base section 12 and cover 14 are constructed of a non-metallic material, preferably plastic.
- Conventional metal telecommunications enclosures are generally painted to provide some protection against corrosion. However, these metal enclosures can get dented, scratched or otherwise banged up during installation and over time. This can result in damage to the paint leaving an area that is both unsightly and susceptible to corrosion.
- the dome 14 and base section 12 are made of a high-density polyethylene plastic material.
- the dome and base section 12 can be made using a rotational molding process.
- Other processes capable of producing large objects economically also could be used e.g., twin sheet blow molding, injection molding, etc.
- the enclosure includes an internal mounting frame 30 (see FIG. 4 ).
- the illustrated mounting frame includes a pair of legs 32 that are joined at their upper ends by a crossbar 34 .
- the internal mounting frame 30 can be made of metal to ensure that it has sufficient strength to support the cables, wire bundles or any other equipment housed in the enclosure.
- the mounting frame 30 can be made of galvanized steel that is powder coat painted to provide corrosion resistance. A non-metallic internal mounting frame could also be used.
- Each leg 32 of the mounting frame 30 is attached to a respective one of the lateral sidewalls 20 of the base section 12 .
- each leg 32 has a C-shaped cross-sectional configuration and a lower end of each leg is received in a corresponding C-shaped slot 36 in the base section 12 (see, e.g., FIGS. 9 and 10 ).
- the C-shaped slots 36 in the base section 12 are formed in channels 38 arranged on the inside of each of the lateral sidewalls 20 of the base section (see FIGS. 8-10 ).
- the legs 32 are secured in the C-shaped slots 36 via bolts 40 (see FIGS. 5 and 8 ).
- the base section 12 also includes channels 42 on the inside of the front and rear walls 16 , 18 of the base section. These channels 42 can be used as desired to receive and support any additional mounting frame legs, for example, if the mounting frame 30 includes three legs.
- the upper end of the base section 12 includes a neck 44 that is configured to assist technicians in placing the dome 14 on the base section as shown in FIG. 4 .
- the neck has a tapered or beveled leading edge 46 (see FIGS. 4 and 7 A) that helps direct the dome 14 over the neck 44 when the dome is lowered onto the base section 12 .
- This tapered or beveled edge 46 also defines an inward curl at the top of the base section 12 that helps enhance the rigidity of the base section.
- the neck 44 ends at a vertical rib 48 that extends around the base section 12 and against which the lower edge 50 of the dome 14 abuts when the dome is secured to the base section (see FIGS. 4 and 13 ).
- the lower edge 50 of the dome 14 can also be curled inward as best shown in FIG. 7A to enhance the rigidity of the dome.
- the dome 14 includes four vertically extending ridges 52 (see FIGS. 1-4 ).
- one vertical ridge 52 extends down the center of each side of the dome 14 .
- the vertical ridges 52 on the two lateral sidewalls 26 of the dome 14 align with the legs 32 of the internal mounting frame 30 to facilitate proper placement of the dome 14 on the base section 12 .
- the vertical ridges 52 on the front and rear walls 22 , 24 of the dome align with a third leg of the internal mounting frame in the event one is provided.
- the corresponding channels formed on the inside surface of the dome 14 by the vertical ridges 52 provide additional clearance space around the internal mounting frame 30 .
- the illustrated dome 14 also includes horizontally extending ridges 54 on each of the lateral sidewalls 26 that a technician can use as handles during removal and replacement of the dome 14 .
- the illustrated enclosure 10 includes a latching system or mechanism 56 that operates automatically when the dome 14 is lowered onto the base section 12 .
- the latching mechanism 56 is arranged at the lower edge 50 of the dome 14 and the upper edge or neck 44 of the base section 12 (see FIGS. 1-3 and 12 - 13 ) so as to provide, along with the solid single piece dome, a bell jar effect that provides protection against rising floodwaters.
- the illustrated latching mechanism 56 includes a pair of flap latches 58 with one flap latch 58 being arranged at the lower edge of each of the lateral sidewalls 26 of the dome (see FIG. 2 ).
- each flap latch 58 overhangs a slot or window extending upward from the lower edge 50 of the dome 14 .
- the overhanging portion of each flap latch includes an opening 59 that is adapted to snap over a corresponding post 60 arranged on the neck 44 of the base section 12 .
- the flap latches 58 are constructed of a resiliently flexible material, such as plastic, and are secured to the dome 14 in such a way that the flap latches 58 will deflect in an outward direction over the posts 60 as the dome 14 is lowered onto the base section 12 with the post extending into the slot or window in the dome behind the flap latch (see FIG. 12 ).
- the openings 59 in the flap latches 58 are aligned with the posts 60 on the neck 44 of the base section 12 . This allows the flap latches 58 to snap back inward over the posts 60 thereby securing the dome 14 to the base section 12 (see FIG. 13 ).
- the dome 14 can then be fastened in place via bolts 62 that can be threaded into the ends of the posts 60 .
- the bolts 62 can be conveniently attached to the base section 12 by short chains 63 so that they are not misplaced.
- other latching or securing systems can be used.
- one or more rotary locks may be provided at the lower edge of the dome that would engage complementary receptacles provided in the neck of the base section.
- One or more rotary locks also could be provided at a higher location on the dome. These higher rotary locks would engage complementary receptacles provided on the internal mounting structure.
- the joint between the dome 14 and the base section 12 can be configured to allow some airflow through the enclosure 10 .
- this is achieved by arranging a plurality of indentations 64 along the upper vertical rib 48 and neck 44 of the base section 12 (see FIGS. 2, 9 and 10 ). This arrangement places the airflow passages relatively low on the enclosure 10 so as not to adversely impact the bell jar effect achieved by using the large single piece dome 14 and low latching mechanism 56 .
- Each indentation 64 extends horizontally along the upper edge of the upper vertical rib 48 and then vertically into the neck 44 as best shown in FIGS. 9 and 10 .
- the indentations 64 form airflow paths underneath the lower edge 50 of the dome 14 through which air can flow into the enclosure 10 .
- the airflow paths could be formed in a variety of different ways, however, it is preferred that they be located at a relatively low point on the enclosure 10 so as preserve the bell jar effect.
- the base section 12 has a plurality of integrally formed, horizontally extending channels 66 (see FIGS. 1-4 ).
- the channels 66 extend into the interior of the base section 12 and define corresponding ridges on the inside surface of the walls of the base section 12 .
- This arrangement provides the walls of the base section 12 with a corrugated configuration that increases their strength and rigidity.
- at least a portion of the base section 12 is typically filled with dirt and/or gravel and buried in the ground.
- Underground cable can be fed into the interior space of the enclosure 10 through the open lower end of the base section 12 .
- the base section 12 can have a split configuration. Specifically, the base section 12 could comprise mating front and rear housing sections that could be separated from each other without disturbing (e.g., removal of) the internal mounting frame 32 .
- a flange 68 that extends outward at the lower end of the base section 12 further enhances the stability of the base section in the ground.
- the flange 68 includes a horizontal upper leg 70 that extends outward away from the walls of the base section 12 , a vertically extending connecting portion 72 and a lower leg 74 that extends horizontally back inwards toward the center of the base section 12 .
- This curled back construction of the flange 68 provides the base section 12 with additional rigidity as well as a solid base for mounting either in the ground or above ground on a pad or the lid to a below grade enclosure or vault as described in greater detail below.
- the base section 12 is adapted to receive mounting stakes 76 .
- two mounting stakes 76 are typically driven into the ground to a depth where the upper ends of the stakes extend up into the base section 12 .
- the upper ends of the stakes are then connected to the base section 12 (see FIG. 14 ).
- the lower leg of the flange 68 on the base section 12 includes a cutout portion 78 that allows the stakes 76 to pass upwards into the inside of the base section 12 .
- the enclosure 10 is adapted such that the stakes 76 are received in the channels 38 on the inside of the lateral sidewalls 20 of the base section 12 in which the legs 32 of the mounting frame 30 are supported (see FIGS. 5 and 14 ).
- the legs 32 are received in the slots 36 in the bodies of the channels 38 themselves while the stakes 76 are received in the inside facing groove defined by the channels 38 .
- the stakes 76 can be secured to the base section 12 using the same bolts 40 used to secure the mounting frame legs 32 in the slots 36 .
- the channels 42 on the inside of the front and rear walls could also be used as attachment points for, mounting stakes.
- the base section 12 can be dimensioned such that the channels 38 are spread apart a distance corresponding to a standard stake spacing distance used with existing metal cabinets. This allows the enclosure 10 to be retrofitted into locations that previously had used a metal cabinet without removing the existing stakes. In a retrofit situation, the new enclosure 10 can simply be lowered down over the existing stakes. As can be appreciated, eliminating the need to dig holes for new stakes around buried utility lines substantially simplifies the installation process.
- each bracket 94 includes a first vertical leg 96 that is received in a respective one of the inward facing grooves defined by the channels 38 on the lateral sidewalls 20 of the base section 12 .
- the vertical leg 96 can be secured in the groove using the same bolts 40 used to secure the mounting frame legs 32 in the slots 36 .
- the channels 42 on the inside of the front and rear walls of the base section could also be used as attachment points for the brackets 94 .
- each bracket includes a second horizontal leg 98 that extends into the space between the upper and lower legs 70 , 74 of the flange 68 .
- This second leg 98 includes an opening through which the pad mounting bolts 92 extend when the enclosure 10 is secured to the pad 91 .
- the second horizontal leg 98 of the bracket 94 in this case, has an increased thickness that substantially corresponds to the distance between the upper and lower legs 70 , 74 of the flange 68 .
- the second horizontal leg 98 prevents the flange 68 from deflecting when the pad mounting bolts 92 are tightened down into the pad 91 .
- the mounting frame 30 can include a bonding or grounding strap or bracket 80 that is adapted for easy installation and removal.
- the bonding/grounding strap 80 includes an attached bond bar 81 (see FIGS. 9-11 ) that can be used for grounding the equipment housed in the enclosure 12 .
- each end of the bonding/grounding strap 80 includes a keyhole shaped slot 82 that, in this case, has a relatively larger lower portion 86 and a relatively smaller upper portion 88 (as best shown in FIG. 11 ). As shown in FIG.
- the smaller upper portion 88 of the keyhole slot 82 is sized smaller than the head of a conventional mounting bolt 84 received in the mounting frame legs 32 . Accordingly, when the bolt 84 extends through the upper portion 88 of the keyhole slot 82 and is tightened down, the bonding/grounding strap 80 is secured to the mounting frame 30 .
- the lower portion 86 of the keyhole slot 82 (best shown in FIG. 11 ) is sized larger than the head of the bolt 84 so as to allow the bonding/grounding strap 80 to be installed and removed without completely removing the mounting bolts 84 .
- the mounting bolts 84 can be loosened so that the bonding/grounding strap 80 can be lifted into a release position wherein the bolt heads are aligned with the larger lower portion 86 of the keyhole slots 82 as shown in FIG. 10 .
- the bonding/grounding strap 80 can then be pulled generally horizontally off the mounting frame 30 with the bolt heads passing through the larger portion 86 of the keyhole slots 82 (see FIG. 11 ).
- the bonding/grounding strap 80 is placed on the mounting frame 30 with the bolt heads extending through the larger lower portion 86 of the keyhole slots 82 (see FIG. 10 ).
- the bonding/grounding strap 80 is then lowered so that the bolts are arranged in the smaller upper portion 88 of the keyhole slots 82 (see FIG. 9 ).
- the bolts 84 can then be tightened down on the bonding/grounding strap 80 securing it in position.
- the enclosure 10 alternatively could have a conventionally configured bonding/grounding strap.
- the mounting frame 30 and the enclosure 10 could be adapted to receive bonding/grounding straps already used in existing metal cabinets.
- the bonding/grounding strap for the existing metal cabinet can be removed and reattached to the mounting frame 30 of the enclosure 10 without having to remove any of the equipment attached to the bonding/grounding strap.
- the base section 12 of the enclosure 10 could be adapted to receive the mounting frame used in conventional metal telecommunications cabinets. In such a case, when replacing the metal cabinet, the mounting frame could be removed from the existing metal cabinet and remounted in the new enclosure 10 .

Description
- This invention pertains to a housing for telecommunications equipment.
- At particular points in telecommunications systems, there is a need to splice large pair count cables. One example of such a point would be branching location where one or more large copper cables are divided into a number of smaller cables. A single branching location could have thousands of copper wire splices. Typically, these splices are housed in large outdoor metal cabinets. Such cabinets can be up to five feet tall, three feet across and one foot deep. These metal cabinets are also used to house large fiber-optic and cable television equipment either separately or in the same enclosure with the copper splices.
- The metal cabinets used in these applications generally comprise several pieces of painted galvanized steel that are assembled together with metal hardware to form the cabinet. These cabinets have front doors, and sometimes rear doors, that provide access to the interior of the cabinet. The cabinets are generally secured to the ground using separate metal stakes or mounted on concrete pads.
- Unfortunately, these metal cabinets have a number of drawbacks. For example, they are not particularly resistant to dings, dents and scratches and can become quite beat-up over time or even during the installation process. This adversely affects not only the appearance of the cabinet, but also makes it more susceptible to corrosion. Moreover, because these cabinets are constructed of multiple pieces that are bolted together, they can be difficult to seal against the weather. The doors to the cabinet also can easily be knocked or left open or ajar by careless technicians further compromising the security and integrity of the cabinet. These issues are of particular concern in areas subject to flooding because floodwater can infiltrate the cabinet and the telecommunications equipment can become submerged.
- Another significant issue with these metal cabinets is that access to the interior can be awkward and quite limited. In particular, when installing equipment or performing maintenance in a metal cabinet, the only access is through the doors. If there are only doors on the front of the cabinet, the technician will have unrestricted access to only one side of the equipment. While this can be alleviated somewhat by providing an extra set of doors on the rear of the cabinet, access to the sides will still be limited and, as noted above, the extra doors increase the potential for ajar, misaligned or otherwise improperly sealed parts that compromise the integrity of the cabinet.
- The invention provides an outdoor enclosure for housing telecommunications equipment. The enclosure includes a base section having a generally rectangular cross-sectional configuration including a front wall, a rear wall and a pair of lateral sidewalls. The base section is open at an upper end and a lower end and is made of a non-metallic material.
- The enclosure also includes a single-piece, solid dome having a generally rectangular cross-sectional configuration including a front wall, a rear wall, a top wall and a pair of lateral sidewalls. The dome is open at a lower end and the lower end of the dome is engageable with the upper end of the base section so as to define an interior space in the enclosure. The dome is made of a non-metallic material.
- A latching mechanism is arranged at the upper end of the base section and the lower end of the dome. The latching mechanism is operable to automatically latch the dome and base section together when the dome is arranged on the base section in a predetermined correct orientation.
- A mounting frame is supported on the base section so as to be arranged in the interior space when the dome is engaged with the base section. The mounting frame has two or more legs and each leg is secured to the base section by at least one fastener. Two or more mounting stakes are attachable to the base section using the fasteners connecting the mounting frame legs to the base section.
- A bonding/grounding strap is provided that has first and second ends each of which is attachable to a respective one of the legs of the mounting frame. Each of the first and second ends of the bonding/grounding strap has a keyhole slot for receiving a fastener. The keyhole slots having a first portion that is larger than a head of the fastener such that the head can pass through the first portion and a second portion that is smaller than the head of the fastener such that the head is prevented from passing through the slot.

FIGS. 1-4 of the drawings, there is illustrated an exemplary outdoortelecommunications equipment enclosure 10 constructed in accordance with the teachings of the present invention. As described in greater detail below, theenclosure 10 of the present invention has a rugged, substantially weather resistant and weather-tight construction that makes it ideal for outdoor telecommunications applications. Advantageously, theenclosure 10 also has a relatively large volume that makes it particularly applicable to telecommunications applications involving splicing of large pair count cables. Such applications can involve thousands of copper wire splices. Theenclosure 10 could also be used at locations in telecommunications systems having both copper wire and fiber optic equipment. For example, theenclosure 10 of the present invention could be configured to accommodate from 1,800 to 3,600 copper splice pairs and/or passive fiber optic equipment. Theenclosure 10 could also be used to house large cable television equipment such as splitters or amps and active electronics. For use in such applications, theenclosure 10 should have an internal volume of approximately 10 cubic feet or larger. - To help ensure that the
enclosure 10 is secure against both unauthorized entry and adverse weather conditions, the illustrated enclosure has a relatively simple construction including abase section 12 and a single-piece cover ordome 14. In the illustrated embodiment, both thebase section 12 anddome 14 have a rectangular configuration. As shown inFIGS. 1-4 , thebase section 12 has afront wall 16, arear wall 18 and opposinglateral sidewalls 20 and is open at the top and bottom. Thedome 14 has afront wall 22,rear wall 24, opposinglateral sidewalls 26 and atop wall 28 and is open at the bottom. Thedome 14 nests in a telescoping fashion over thebase section 12 with the open bottom of thedome 14 fitting over the open top of thebase section 12 so as to define an interior space within theenclosure 10. In this case, thetop wall 28 of thedome 14 is pitched so as to prevent an accumulation of snow or water on top of theenclosure 10. - Advantageously, the single piece, solid wall construction of the
dome 14 eliminates the joints or seams that result from the multi-piece construction of the upper portion of existing metal cabinets. As will be appreciated, this effectively eliminates the opportunity for water leakage into the interior of theenclosure 10, thereby creating a “bell-jar” effect. Additionally, by eliminating the doors, the risk that a technician will not securely close theenclosure 10 is substantially reduced. An additional advantage of the single piece,solid dome 14 is that a technician has unrestricted 3600 access to the interior of theenclosure 10 when the dome is lifted off thebase section 12. As a result, it is much easier to install and maintain the equipment in theenclosure 10 as compared to having to work through a doorway on a conventional metal telecommunications cabinet. - To provide protection against dents and scratches as well as corrosion resistance, the
base section 12 and cover 14 are constructed of a non-metallic material, preferably plastic. Conventional metal telecommunications enclosures are generally painted to provide some protection against corrosion. However, these metal enclosures can get dented, scratched or otherwise banged up during installation and over time. This can result in damage to the paint leaving an area that is both unsightly and susceptible to corrosion. Through the use of anon-metallic dome 14 andbase section 12, the potential for such corrosion damage is eliminated with the present invention. According to a preferred embodiment of the present invention, thedome 14 andbase section 12 are made of a high-density polyethylene plastic material. Moreover, to ensure that thedome 14 andbase section 12 have the rigidity and strength necessary for an enclosure of this size, the dome and base section can be made using a rotational molding process. Other processes capable of producing large objects economically also could be used (e.g., twin sheet blow molding, injection molding, etc.) - To support the cabling, splices or other electronics, the enclosure includes an internal mounting frame 30 (see
FIG. 4 ). The illustrated mounting frame includes a pair oflegs 32 that are joined at their upper ends by acrossbar 34. Theinternal mounting frame 30 can be made of metal to ensure that it has sufficient strength to support the cables, wire bundles or any other equipment housed in the enclosure. In particular, the mountingframe 30 can be made of galvanized steel that is powder coat painted to provide corrosion resistance. A non-metallic internal mounting frame could also be used. - Each
leg 32 of the mountingframe 30 is attached to a respective one of thelateral sidewalls 20 of thebase section 12. In this case, eachleg 32 has a C-shaped cross-sectional configuration and a lower end of each leg is received in a corresponding C-shapedslot 36 in the base section 12 (see, e.g.,FIGS. 9 and 10 ). The C-shapedslots 36 in thebase section 12 are formed inchannels 38 arranged on the inside of each of thelateral sidewalls 20 of the base section (seeFIGS. 8-10 ). Thelegs 32 are secured in the C-shapedslots 36 via bolts 40 (seeFIGS. 5 and 8 ). In this case, thebase section 12 also includeschannels 42 on the inside of the front andrear walls channels 42 can be used as desired to receive and support any additional mounting frame legs, for example, if the mountingframe 30 includes three legs. - The upper end of the
base section 12 includes aneck 44 that is configured to assist technicians in placing thedome 14 on the base section as shown inFIG. 4 . The neck has a tapered or beveled leading edge 46 (seeFIGS. 4 and 7 A) that helps direct thedome 14 over theneck 44 when the dome is lowered onto thebase section 12. This tapered orbeveled edge 46 also defines an inward curl at the top of thebase section 12 that helps enhance the rigidity of the base section. Theneck 44 ends at avertical rib 48 that extends around thebase section 12 and against which thelower edge 50 of thedome 14 abuts when the dome is secured to the base section (seeFIGS. 4 and 13 ). Thelower edge 50 of thedome 14 can also be curled inward as best shown inFIG. 7A to enhance the rigidity of the dome. - To further assist technicians in placing the
dome 14 on thebase section 12, thedome 14 includes four vertically extending ridges 52 (seeFIGS. 1-4 ). In this case, onevertical ridge 52 extends down the center of each side of thedome 14. Thevertical ridges 52 on the twolateral sidewalls 26 of thedome 14 align with thelegs 32 of the internal mountingframe 30 to facilitate proper placement of thedome 14 on thebase section 12. Thevertical ridges 52 on the front andrear walls dome 14, the corresponding channels formed on the inside surface of thedome 14 by thevertical ridges 52 provide additional clearance space around the internal mountingframe 30. The illustrateddome 14 also includes horizontally extendingridges 54 on each of thelateral sidewalls 26 that a technician can use as handles during removal and replacement of thedome 14. - To secure the
dome 14 to thebase section 12, the illustratedenclosure 10 includes a latching system ormechanism 56 that operates automatically when thedome 14 is lowered onto thebase section 12. Advantageously, thelatching mechanism 56 is arranged at thelower edge 50 of thedome 14 and the upper edge orneck 44 of the base section 12 (seeFIGS. 1-3 and 12-13) so as to provide, along with the solid single piece dome, a bell jar effect that provides protection against rising floodwaters. The illustratedlatching mechanism 56 includes a pair of flap latches 58 with oneflap latch 58 being arranged at the lower edge of each of thelateral sidewalls 26 of the dome (seeFIG. 2 ). A portion of each flap latch 58 overhangs a slot or window extending upward from thelower edge 50 of thedome 14. The overhanging portion of each flap latch includes anopening 59 that is adapted to snap over a corresponding post 60 arranged on theneck 44 of thebase section 12. - The flap latches 58 are constructed of a resiliently flexible material, such as plastic, and are secured to the
dome 14 in such a way that the flap latches 58 will deflect in an outward direction over the posts 60 as thedome 14 is lowered onto thebase section 12 with the post extending into the slot or window in the dome behind the flap latch (seeFIG. 12 ). Once thedome 14 reaches its fully closed position, theopenings 59 in the flap latches 58 are aligned with the posts 60 on theneck 44 of thebase section 12. This allows the flap latches 58 to snap back inward over the posts 60 thereby securing thedome 14 to the base section 12 (seeFIG. 13 ). To further prevent any unintentional dislodging of thedome 14, it can then be fastened in place viabolts 62 that can be threaded into the ends of the posts 60. As in the case of the illustrated embodiment, thebolts 62 can be conveniently attached to thebase section 12 byshort chains 63 so that they are not misplaced. As will be appreciated by those skilled in the art, other latching or securing systems can be used. For example, one or more rotary locks may be provided at the lower edge of the dome that would engage complementary receptacles provided in the neck of the base section. One or more rotary locks also could be provided at a higher location on the dome. These higher rotary locks would engage complementary receptacles provided on the internal mounting structure. - If desired, such as to facilitate operation of the equipment housed in the
enclosure 10, the joint between thedome 14 and thebase section 12 can be configured to allow some airflow through theenclosure 10. In the illustrated embodiment, this is achieved by arranging a plurality ofindentations 64 along the uppervertical rib 48 andneck 44 of the base section 12 (seeFIGS. 2, 9 and 10). This arrangement places the airflow passages relatively low on theenclosure 10 so as not to adversely impact the bell jar effect achieved by using the largesingle piece dome 14 andlow latching mechanism 56. Eachindentation 64 extends horizontally along the upper edge of the uppervertical rib 48 and then vertically into theneck 44 as best shown inFIGS. 9 and 10 . When thedome 14 is on thebase section 12, theindentations 64 form airflow paths underneath thelower edge 50 of thedome 14 through which air can flow into theenclosure 10. As will be appreciated by those skilled in the art, the airflow paths could be formed in a variety of different ways, however, it is preferred that they be located at a relatively low point on theenclosure 10 so as preserve the bell jar effect. - To help stabilize the enclosure when it is mounted in the ground, the
base section 12 has a plurality of integrally formed, horizontally extending channels 66 (seeFIGS. 1-4 ). Thechannels 66 extend into the interior of thebase section 12 and define corresponding ridges on the inside surface of the walls of thebase section 12. This arrangement provides the walls of thebase section 12 with a corrugated configuration that increases their strength and rigidity. When in use, at least a portion of thebase section 12 is typically filled with dirt and/or gravel and buried in the ground. Underground cable can be fed into the interior space of theenclosure 10 through the open lower end of thebase section 12. The corrugated configuration of the walls of thebase section 12 allows the dirt or gravel to infiltrate better around the base section thereby making the base section harder to remove from the ground. To simplify retrofitting of theenclosure 10 into applications that previously had used conventional metal telecommunications cabinets or to facilitate repair or replacement of the equipment housed in the enclosure, thebase section 12 can have a split configuration. Specifically, thebase section 12 could comprise mating front and rear housing sections that could be separated from each other without disturbing (e.g., removal of) the internal mountingframe 32. - A
flange 68 that extends outward at the lower end of thebase section 12 further enhances the stability of the base section in the ground. As best shown inFIG. 7B , in the illustrated embodiment, theflange 68 includes a horizontalupper leg 70 that extends outward away from the walls of thebase section 12, a vertically extending connecting portion 72 and alower leg 74 that extends horizontally back inwards toward the center of thebase section 12. This curled back construction of theflange 68 provides thebase section 12 with additional rigidity as well as a solid base for mounting either in the ground or above ground on a pad or the lid to a below grade enclosure or vault as described in greater detail below. - For applications in which the
enclosure 10 is mounted in the ground, thebase section 12 is adapted to receive mountingstakes 76. When used, two mountingstakes 76 are typically driven into the ground to a depth where the upper ends of the stakes extend up into thebase section 12. The upper ends of the stakes are then connected to the base section 12 (seeFIG. 14 ). As shown inFIG. 5 , the lower leg of theflange 68 on thebase section 12 includes acutout portion 78 that allows thestakes 76 to pass upwards into the inside of thebase section 12. To enhance the stability of thebase section 12 and mountingframe 32, in the illustrated embodiment, theenclosure 10 is adapted such that thestakes 76 are received in thechannels 38 on the inside of thelateral sidewalls 20 of thebase section 12 in which thelegs 32 of the mountingframe 30 are supported (seeFIGS. 5 and 14 ). In particular, thelegs 32 are received in theslots 36 in the bodies of thechannels 38 themselves while thestakes 76 are received in the inside facing groove defined by thechannels 38. Thestakes 76 can be secured to thebase section 12 using thesame bolts 40 used to secure the mountingframe legs 32 in theslots 36. If desired, thechannels 42 on the inside of the front and rear walls could also be used as attachment points for, mounting stakes. - Advantageously, the
base section 12 can be dimensioned such that thechannels 38 are spread apart a distance corresponding to a standard stake spacing distance used with existing metal cabinets. This allows theenclosure 10 to be retrofitted into locations that previously had used a metal cabinet without removing the existing stakes. In a retrofit situation, thenew enclosure 10 can simply be lowered down over the existing stakes. As can be appreciated, eliminating the need to dig holes for new stakes around buried utility lines substantially simplifies the installation process. - As shown in
FIGS. 15 and 16 , when mounting theenclosure 10 on apad 91,pad mounting bolts 92 can be extended into the pad through theflange 68. A generally L-shapedbracket 94 can also be provided at each bolt location. As best shown inFIG. 16 , eachbracket 94 includes a firstvertical leg 96 that is received in a respective one of the inward facing grooves defined by thechannels 38 on thelateral sidewalls 20 of thebase section 12. Thevertical leg 96 can be secured in the groove using thesame bolts 40 used to secure the mountingframe legs 32 in theslots 36. Thechannels 42 on the inside of the front and rear walls of the base section could also be used as attachment points for thebrackets 94. To receive thepad mounting bolts 92, each bracket includes a secondhorizontal leg 98 that extends into the space between the upper andlower legs flange 68. Thissecond leg 98 includes an opening through which thepad mounting bolts 92 extend when theenclosure 10 is secured to thepad 91. To provide support for theflange 68, the secondhorizontal leg 98 of thebracket 94, in this case, has an increased thickness that substantially corresponds to the distance between the upper andlower legs flange 68. Thus, the secondhorizontal leg 98 prevents theflange 68 from deflecting when thepad mounting bolts 92 are tightened down into thepad 91. - For supporting the cables or other equipment in the
enclosure 10, the mountingframe 30 can include a bonding or grounding strap orbracket 80 that is adapted for easy installation and removal. In the illustrated embodiment, the bonding/grounding strap 80 includes an attached bond bar 81 (seeFIGS. 9-11 ) that can be used for grounding the equipment housed in theenclosure 12. To facilitate attachment to the mountingframe 30, each end of the bonding/grounding strap 80 includes a keyhole shapedslot 82 that, in this case, has a relatively largerlower portion 86 and a relatively smaller upper portion 88 (as best shown inFIG. 11 ). As shown inFIG. 9 , the smallerupper portion 88 of thekeyhole slot 82 is sized smaller than the head of aconventional mounting bolt 84 received in the mountingframe legs 32. Accordingly, when thebolt 84 extends through theupper portion 88 of thekeyhole slot 82 and is tightened down, the bonding/grounding strap 80 is secured to the mountingframe 30. Thelower portion 86 of the keyhole slot 82 (best shown inFIG. 11 ) is sized larger than the head of thebolt 84 so as to allow the bonding/grounding strap 80 to be installed and removed without completely removing the mountingbolts 84. In particular, to remove the bonding/grounding strap 80, the mountingbolts 84 can be loosened so that the bonding/grounding strap 80 can be lifted into a release position wherein the bolt heads are aligned with the largerlower portion 86 of thekeyhole slots 82 as shown inFIG. 10 . The bonding/grounding strap 80 can then be pulled generally horizontally off the mountingframe 30 with the bolt heads passing through thelarger portion 86 of the keyhole slots 82 (seeFIG. 11 ). - The same procedure is used in reverse to install the bonding/
grounding strap 80. Specifically, the bonding/grounding strap 80 is placed on the mountingframe 30 with the bolt heads extending through the largerlower portion 86 of the keyhole slots 82 (seeFIG. 10 ). The bonding/grounding strap 80 is then lowered so that the bolts are arranged in the smallerupper portion 88 of the keyhole slots 82 (seeFIG. 9 ). Thebolts 84 can then be tightened down on the bonding/grounding strap 80 securing it in position. As will be appreciated, theenclosure 10 alternatively could have a conventionally configured bonding/grounding strap. Moreover, the mountingframe 30 and theenclosure 10 could be adapted to receive bonding/grounding straps already used in existing metal cabinets. This makes it much easier to replace metal telecommunications cabinets already installed in the field with the enclosure of the present invention. In particular, the bonding/grounding strap for the existing metal cabinet can be removed and reattached to the mountingframe 30 of theenclosure 10 without having to remove any of the equipment attached to the bonding/grounding strap. Likewise, thebase section 12 of theenclosure 10 could be adapted to receive the mounting frame used in conventional metal telecommunications cabinets. In such a case, when replacing the metal cabinet, the mounting frame could be removed from the existing metal cabinet and remounted in thenew enclosure 10. - All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
