Electrical equipment casing

Cross Reference to Related Applications

This application is the first patent application directed to the invention and its subject matter.

Technical Field

The utility model relates to a device for holding electrical equipment. The invention also relates to a method of manufacturing a housing for an electrical device.

Background

It is known to house electrical equipment, primarily to support the equipment and to restrict access to the equipment. Typically, such equipment is stored in a climate controlled environment, and standard metal racks and enclosures are available for this purpose. However, it is sometimes necessary to house electrical equipment at an external location, for example, when the equipment is required to perform operations related to a railroad. Furthermore, devices can handle traditional mains level or higher voltages, and therefore, it becomes more important to restrict access to the devices.

A problem arises when using metal cabinets for housing electrical equipment outdoors. Regular maintenance is necessary, otherwise the metal cabinet can deteriorate significantly due to weather reasons. This type of enclosure is also susceptible to graffiti, damage and theft.

To overcome the problems associated with the use of metal chassis, other materials have been utilized. The other materials typically have highly protective exterior surfaces, which can be of great benefit to the integrity of the cabinet structure. However, if these outer surfaces are penetrated during the manufacturing process, such structures would be compromised.

SUMMERY OF THE UTILITY MODEL

According to a first aspect of the present invention, there is provided a casing for housing electrical equipment, comprising: a substrate; a plurality of walls, each wall having a durable outer surface and side edges; connecting means for connecting said plurality of walls at adjacent edges without penetrating said durable outer surface; and a shell top.

In one embodiment, the substrate includes a durable lower outer surface and a durable upper inner surface; and the durable upper inner surface includes a base recess for receiving the lower edge of the wall. The edges may be bevelled such that the walls are connected at the adjacent edges by abutting the respective bevelled edges.

Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings. The detailed embodiments represent the best mode known to the inventors and provide support for the claimed invention. However, they are merely exemplary and should not be used to interpret and limit the scope of the claims. Their purpose is to provide teachings to those skilled in the art. The components and processes distinguished by ordinal words (e.g., "first," "second") do not necessarily define the order or ranking of any class.

Detailed Description

FIG. 1 shows a schematic view of a

Fig. 1 shows a housing 101 for accommodating electrical equipment. In this example, the enclosure 101 is located proximate to a railway line 102 and includes electrical equipment associated with a railway related system. The casing 101 is exposed to the environment and therefore should be constructed to resist environmental degradation. Additionally, the enclosure should be resistant to vandalism, including unauthorized painting.

The housing 101 includes a plurality of walls and a top. The walls and the shell roof are formed of a high pressure dense laminate of the type described with reference to fig. 2.

FIG. 2

Fig. 2 shows a high pressure dense laminate 201 comprising a core 202 and an outer surface 203. The outer surface includes a urethane acrylate adhesive. In one embodiment, a similar inner surface 204 is provided, which is also formed from a urethane acrylate adhesive.

Materials of the type shown in fig. 2 are available from commercial sources (e.g., the company Trespa International BV, the netherlands) under the trade name Trespa (registered trademark) Meteon (registered trademark). The material may be referred to as a "panel" because it primarily serves as an outer cover. A typical example has a thickness of 8 mm and the material has a life expectancy of 50 years.

The Trespa Meteon is a low-maintenance decorative building panel comprised of 70% by weight paper or residual wood from the softwood industry process and 30% by weight phenolic binder, forming the core 202. The binder is a fully hardened, insoluble thermosetting resin, which in this example is made of phenol/formalin.

In such formulations, the outer surface may be decorative and include pigments in a solvent-free urethane acrylate binder that is fully cured and hardened. This particular embodiment does not use heavy metals, biocides, plasticizers, inorganic fibers, halogens, and any ozone depleting products or preservatives.

Thus, in one embodiment, the walls and shell top are cut from a panel of high pressure dense laminate and have cut edges. The cut edge is protected by applying a primer. A grinding operation is performed on the cut edge, followed by a cleaning operation, prior to applying the primer.

In an embodiment, the enclosure provides a housing for electrical equipment and comprises a base, a plurality of walls, and a roof, wherein each wall has a durable outer surface and side edges, and connecting means for connecting the plurality of walls at adjacent edges (without penetrating the durable outer surface).

FIG. 3

Fig. 3 shows a base panel 301 for a chassis. A preferred construction method involves cutting a substrate recess 302 into the upper surface 303 of the substrate panel 301. Prior to gluing, the edges 304 and the cut-out depression are protected by applying a primer. For the application described with reference to fig. 1, an adhesive made for structural glazing is considered acceptable when the housing is exposed to environmental conditions, taking into account the inherent resistance of the adhesive to degradation under ultraviolet light. This type of adhesive is supplied by Sika Services AG of switzerland and has the trade name Sikasil (registered trademark). Prior to applying the adhesive, the surface (e.g., substrate recess 302) must be clean, dry, and free of oil. Mechanical grinding was performed on the surfaces to be bonded using a centrifugal grinder with a particle size value of 80.

After the grinding operation, the surface is cleaned with a clean, oil-free and lint-free cloth or cleaning paper immersed in a suitable cleaning solution (e.g., a commercial Sika cleaning 205 manufactured by Sika Services AG). Wiping should be done in one direction only and the cleaning cloth should be replaced regularly. Thereafter, a 10 minute ventilation period is required before any further action can be taken.

After the surface has been cleaned, a primer, such as a commercial Sika Tack panel primer manufactured by Sika Services AG, is applied. The primer is applied uniformly with a brush or felt on the machined surface and requires a venting period of at least 30 minutes before the adhesive is applied.

A similar priming operation is applied to the edge 304 of the base panel 301, although no adhesive is required per se.

FIG. 4

Fig. 4 shows a first wall 401 of the cabinet, cut from the panel shown in fig. 2. The wall 401 has a durable outer surface 402 and in this embodiment also a similar durable inner surface 403. Connecting means are provided to connect the walls at adjacent edges (e.g., edge 404). In one embodiment, integrity is maintained by joining the walls at adjacent edges without penetrating the durable outer surface.

To this end, in the embodiment of FIG. 4, the edges (including the first edge 404) are beveled. The walls are then joined at adjacent edges by abutting the respective beveled edges.

In this embodiment, the connection means comprises a plurality of connection members as described with reference to fig. 6.

FIG. 5

To account for the spread of the connectors, holes 501 are cut in the beveled edges 404. Similar holes are cut in the other beveled edges and additional holes are cut in each beveled edge. In the example shown in fig. 5, a single aperture 501 is shown for illustrative purposes. However, additional apertures may be included in each angled edge, with appropriate spacing between apertures for different sized chassis.

In the embodiment described with reference to fig. 11 to 16, a total of 3 holes are cut in each beveled edge to accommodate 3 similar connecting means between the beveled edges.

FIG. 6

In an embodiment, each connector comprises a first connector portion 601 which engages with a second connector portion 602. The first connector portion 601 is located in the first inclined edge and the second connector portion 602 is located in the second inclined edge.

In an embodiment, the two beveled edges receive a substantially similar component as the second portion 602 via their respective apertures. The first portion 601 includes a positioning section 603 and an extension section 604. Thus, the first connector portion 601 is first positioned in a channel (similar to channel 605) by its positioning section 603, and thereafter engagement is achieved by receiving the extension section 604 in the second portion 602.

FIG. 7

As shown in fig. 7, the second portion 602 is positioned in the hole 501 using a suitable application tool 701.

FIG. 8

After the application tool (as described with reference to fig. 7) has been used, the first portion 601 is positioned (in the second portion 602) by means of the positioning segment 603. The resulting combination effectively defines a first partial subassembly and each subassembly of this type is assembled independently, as shown in fig. 8.

Examples of such connectors are available through OVVO technology (registered trademark) of lousbane of the republic of ireland.

Installation instructions from the OVVO technique indicate that the connectors should be received in the holes 501 such that they are flush with the surface of the rim 404. However, in this embodiment, the holes 501 are ground to a shallower depth so that they extend slightly beyond the surface of the rim 404 when the connector portions are received. Thus, as the edges come together, a gap is created between them for receiving an adhesive of the type described above.

FIG. 9

As shown in fig. 9, in this embodiment, the walls are assembled by receiving the extensions 604 in respective channels 605. Prior to attachment as shown in fig. 9, an adhesive is applied to each surface.

FIG. 10 shows a schematic view of a

As shown in fig. 10, the first wall 401 has been connected to the second wall 1001. The position of the connectors is such that a gap 1002 is created between the first wall 401 and the second wall 1001. Gap 1002 provides space for adhesive that was previously applied to the beveled edges, including edge 404.

Thus, the extension 604 is located in the channel 605. The extension is then secured by the channel by displacement of the second wall 1001 relative to the first wall 401.

FIG. 11

The utility model provides a method for constructing a casing for containing electrical equipment. As described with reference to fig. 3, a substrate recess 302 is cut into the upper surface 303 of the substrate 301. The first wall 401 is located in a portion of the substrate recess.

In the arrangement shown in fig. 11, the beveled edge 404 includes a first connector 1101, a second connector 1102, and a third connector 1103.

FIG. 12

According to the method of this embodiment, the second wall 1101 is also located in a portion of the base recess 302. Thus, as described above, both the first and second walls include durable outer surfaces and side edges.

FIG. 13

As depicted in fig. 13, the first edge 404 of the first wall 401 has been connected to the second edge of the second wall 1001. Furthermore, this connection has been achieved without penetrating the durable outer surface of the first wall and without penetrating the durable outer surface of the second wall.

FIG. 14

Fig. 14 shows the inner surface 402 of the first wall 401. Also shown is the inner surface 1401 of the second wall 1001, the two walls being connected at their edges. In this embodiment, the chassis also includes a stiffener 1402 located at an inner corner defined by the connected edges of the walls. In one embodiment, the reinforcing ribs 1402 have a substantially triangular cross-section and are attached to the inner corners using an adhesive of the type described above.

In one embodiment, a large amount of adhesive is applied to ensure that a weather tight seal is established, and any excess adhesive on the outer corners can be removed by using a suitable tool.

FIG. 15 shows a schematic view of a

After attaching the second wall 1001 to the first wall 401 (described with reference to fig. 12 and 13) and deploying the ribs 1402 (described with reference to fig. 14), a similar operation may be performed to attach the third wall 1501.

FIG. 16

To complete the entire chassis, a fourth wall 1601 is attached to the third wall 1501 and the second wall 1001. To leave access, a hinged door 1602 is provided as part of the fourth wall.

A shell top 1603 is used and a lower surface of shell top 1603 may include a shell top recess, substantially similar to base recess 302, for receiving an upper edge of a wall.

In the embodiment shown in fig. 16, the side edges at the top of each sidewall (including third wall 1501) have an angle such that the housing top 1603 is angled when engaged with the wall.

FIG. 17

Fig. 17 shows an alternative connection means for connecting the walls at adjacent edges. In this alternative embodiment, fitting 1701 has an outer portion 1702 and an inner portion 1703. The outer portion 1702 and the inner portion 1703 may be molded from a thermoplastic material, such as polyvinyl chloride (PVC). Outer portion 1702 defines an elongate right-angled channel section with elements 1704 extending inwardly from the apex of the channel. Similar to the outer portion 1702, the inner portion 1703 defines a second, long, right-angled channel segment. The inner portion 1703 has elements 1705 extending outwardly from the apex of the channel. The two parts are joined by sliding the opposing halves toward each other, engaging element 1704 with element 1705.

Thus, in this alternative embodiment, fitting 1701 has a "two-part" structure including opposing halves that, when connected, define a V-shaped channel section. As shown, in this alternative embodiment, adjacent walls are aligned relative to outer portion 1702 and abut inwardly extending elements 1704. The inner portion 1703 is then pushed against the inside corner of the adjacent wall and the inwardly extending elements 1705 of the outer portion 1703 engage with the outwardly extending elements 1704 of the inner portion 1703 to join the two parts.
