Electronics and instrumentation case and corner piece for that

Background of the Invention

The present invention relates to an electronics and instrumentation enclosure for use in electronics, electrical and instrument mounting, comprising four angular members having first mounting means for mounting a PE / N rail or the like and attaching points for attachment to the corner members of a deck structure. for securing the rail, the first struts extending from the first corner to the second corner and the second extending at a distance from the first strut 10 parallel to the first strut from the third to the fourth corner, the supports being separate from the angles and a first mounting means for mounting the PE / N rail or the like in the corner portion.

15 The components to be mounted on the mounting rail are typically modular components and the mounting rail is typically a DIN rail.

The invention also relates to a corner portion for an electronics and instrumentation housing comprising a first mounting means for mounting a PE / N rail or the like to a corner portion and an attachment point 20 for mounting on a corner portion of a cover structure comprising a first mounting means for securing the support; which is the support for mounting the component rail • • · • * · *.

• ·: Y: There are many types of enclosures used in electronics, electrical and appliance installation. However, in many enclosures the basic functions are the same; • «· 25, ie the enclosure must have a connection point where the electrical wires to be inserted inside the enclosure can be attached; in addition, the enclosure must have supports that can be used to • • · mount a mounting rail that supports the components. The mounting rail is. . often a DIN rail (DIN-15 or DIN-35) to which modular components such as fuses, circuit breakers, transformers, etc. can be mounted

'·; · 30 Known cases where the supports are attached to the bottom plate of the case.

: In cases where the supports are separate, elongated pieces attached to the bottom of the case: the bottom plates of the case must have different sizes depending on the size of the case. This will significantly increase the manufacturing cost. The bottom plate can also make it difficult to install the case if the mounting base is not level: '· 35 different types of mounting brackets must be used on the walls of the case and aesthetically pleasing gaps remain between the base and the base. Further, in all applications 2 110.28, the bottom is not necessary: for example, in applications where the housing is not required to withstand dust or water, the bottom plate is a useless, cost-increasing component.

Also known are bottomless housings in which said supports are integrated integrally with the corner portions of the housing. When the brackets are integrated, each housing size must have a different support bracket unit. Because the design of the corner parts is typically relatively complex, the corner parts are made of plastic. Thus, known support-corner unit units are relatively large plastic units. Manufacturing a plastic unit is expensive because of the fact that a plastic mold for making it is very expensive. A large plastic mold is typically expensive. While custom molds are naturally required for different sized plastic units, the manufacturing of the support-corner unit constitutes a significant part of the manufacturing cost of the electronics and instrumentation case.

Regardless of whether the housing has an integrated support-15 corner unit or includes a separate support to be attached to the base, the wires and cables are more or less difficult to connect due to the relatively closed construction of the housing. The insertion of cables into the enclosure requires that the base and / or supports comprise a plurality of debonding blanks, i.e. breakthrough blanks or break-in blanks, which must be broken in order to enter the enclosure. The more wires or cables you have to insert into the case, the more difficult the job.

Y 35 Figure 1 shows an electronic and instrumentation Y ·; Fig. 3 is a perspective view of Fig. 2, Fig. 4 shows a detail (corner piece) of Fig. 2, and Fig. 5 shows a second detail (support) of Fig. 2.

Detailed Description of the Invention

The electronics and instrumentation enclosure shown in Fig. 1 comprises a cover structure 13 with an opening so that the in-line fuses 50 or other module components contained within the enclosure are accessible and visible. The lid structure is secured to the corner body portions 1 to 4 of the housing body structure by four screw-like members 51 with an eccentrically mounted tile at its ends. The tiles are not shown as they are known in the art. By rotating the members arranged in the locking position 51 semicircularly, the slabs are released from their respective attachment points (9 in Fig. 3) and the deck structure can be lifted out of the frame structure below.

Figures 2 and 3 illustrate the housing frame structure obliquely from above. As shown above, the cover structure 13 of Figure 1 engages at points 9-12 of the frame structure.

The frame structure comprises four identical angular sections 1-4 and their associated brackets 14, 15. A standard DIN-20 mounting rail 16 (DIN-15 or DIN-35), etc., to which the automatic fuses of Figure 1 are attached, is mounted on the supports 14, 15. 50 (or other module components) are attached. For the sake of simplicity, the latter have been omitted from Figure 2. PE / N rails 30, 52 are also fastened to the corner sections 1-4.

The corner portions 1 to 4 comprise a first grooved recess 5 to 25 · 8 for receiving a PE / N rail 30. Recesses 5-8 have bore 41 (see Figs.

The corner portion 1), the hole or recess where the rail 30 is secured by the screw 60. As shown in FIG. 2, the corner portions 1-4 comprise a second grooved recess 25-28 with bores 42 to which the rail can be attached. The recesses 5, 25 and their bores 41, 42 are arranged symmetrically with respect to the line X-X on both sides of this line, which passes through the corner pieces and is at an angle of 45 ° to the supports 14, 15. In other respects, the corner piece 1 is symmetrical with respect to the line X -X.

Reference numerals 17-20 indicate the first fastening means for the corner portions 1-4 by which the supports 14, 15 engage the corner portions. The first fastening means 35 consist of elevation pieces 17-20 having a hole in which the supports 14, 15 are fastened by screws 61. Reference numeral 39 indicates a lateral support of the corner piece 1 which prevents the support 14 from rotating relative to the corner piece when the support 14 is in place 17.

Fig. 2 shows that the corner parts 1-4 also comprise the second fastening means 21-24. The second fastening means 21-24 and the first fastening means 17-20 are arranged symmetrically to the lines X-X and X '-X' drawn on the angles, . The purpose of the second securing means 21-24 is to function in the same manner as the first securing means 17-20, i.e. receiving the supports, if the angular parts 1 to 4 are rotated 90 °.

10 The line X-X of the corner portion 1 is provided with a mounting lug with mounting holes 31 for fastening the corner piece and the casing directly to the base, typically to a wall, cf. Fig. 3. Alternatively, the base may be, in the case of a dense housing structure, the housing base portion 29. The corner portions 2-4 have corresponding fastening lugs with fastening holes 32-34. for reception. The raised portion 35 has a hole for a screw (not shown) for attaching the PE / N rail 52 to the angled portion. Corner portions 2-4 have corresponding protuberance portions 36-38. When lines are drawn from the hole in the protuberance portion 35 to the bores 41 and 42 of the recesses 5 and 25, a rectangular angle is formed with the hole of the protrusion portion located at the tip. Thanks to the said positioning, the PE / N rails of the same length as the recesses 5 and 8 (and 15 and 28) can be attached to the raised members 35 and 38. Thus, the same PE / N rail can alternatively be placed in recesses 5 and 8 or on the base members 35 and 38. The raised parts 35 and 38 are located higher than the recesses 5 and 8.

The purpose of the above arrangement is that by turning the · ···. 25 parts 90 °, alternatively it can be mounted at any of the four corners of the frame structure of Figure 2. That is, the angular part 1 could alternatively be in place of the angular part 4, whereby the recess 25 and bore 42 * * * '·' of the angular part 1 would be used to secure the rail 30, the securing lug 21 would be used to secure the support 15. Because of that,

: 30 that the latches 31-34 and the lugs 35-38 are arranged as described,

I «I

the angular member can be rotated 90 ° so that the same mounting lugs and the same heeling members act as clamping means. The same operation, but in a much more complex manner, could be accomplished by using in each corner portion two raised portions and two securing lugs symmetrically aligned with the X-35 X line, whereby the recess portions should have recesses of: '* ,! additional drilling.

116028 6 The DIN rail 16 is fixed to the supports 14, 15 by means of screws 54, 55, for which the supports comprise holes 53.

Figure 4 shows that there is a large amount of space S between the support 14 and the base 29, which facilitates the installation of the cables.

In Fig. 4, reference numeral 9 indicates the upper end of the corner portion 1 and the attachment point to which the screw member 51 of Fig. 1 engages. The plate at the lower end of the screw member 51 is positioned beneath the surface 56 when the cover structure 13 is locked in the corner portion 1. Reference numeral 57 indicates a pin to insert a corresponding hole in the contact guard plate (not shown). Corner portions 2-4 have corresponding attachment points 10 -12.

Figure 5 shows that the support 14 of Figure 2 is a simple profile piece. It is light and stiff. Preferably, the support 14 is made of metal. Preferably, the support comprises weakening points 55 which allow the support 14 to be manually breakable to the desired length, depending on the size of the housing.

The invention has been described above by means of only one preferred embodiment and it is therefore emphasized that the invention is practicable in many ways within the scope of the appended claims. Thus, for example, instead of grooves 5 to 8, 25 to 28, mounting means formed in other ways may be used; instead of the lifting members 17-24, 20 other fastening means may be used.
