Abstract

Cladding for electrical material intended for use in an operating environment includes a rear cladding section (11), which can be mounted against a wall or floor, and a first cladding section (21, 22) fixed to the rear cladding section. Edge parts of the various cladding sections, which are bordering against one another are angled to form a labyrinth-shaped overlap assembly, which protects against drip water while still allowing air to flow through. The first cladding section (21) extends higher than the rear cladding section (11), whereby it forms, when the cladding is mounted on a wall (10), a channel-shaped pocket (30) between the first cladding section and the wall, where an exhaust opening (29) protected against drip water can be positioned for ventilation air.

Den foreliggende opfindelse angår en kapsling til elektrisk materiel, specielt elektronisk udrustning bestemt til opstilling i procesmiljø.The present invention relates to an enclosure for electrical equipment, in particular electronic equipment intended for installation in a process environment.

Til en kapsling af denne art kræves blandt andet 5 a) at den skal give beskyttelse mod dryppende vand ved en drypvinkel på op til 30° fra lodlinien, b) at den er indrettet til kraftig luftgennemstrømning, så at den kan klare mindst 300 W tabseffekt med acceptabel indre temperaturstigning (ca. 10-15°C), 10 c) at den udgør en betryggende berøringsbeskyttelse (kapslings- klasse IP 20), d) at den har en servicevenlig udførelse med mulighed for lågelisning, og e) at den til speciel anvendelse skal kunne forsynes med pak-15 ning for høj kapslingsklasse.A housing of this kind is required, inter alia, 5 a) to provide protection against dripping water at a drip angle of up to 30 ° from the vertical, b) it is designed for strong air flow so that it can withstand at least 300 W loss power with acceptable internal temperature rise (about 10-15 ° C), 10 c) it provides a reassuring touch protection (enclosure class IP 20), d) has a service-friendly design with capability for low-visibility, and e) special use must be capable of being provided with a seal for high protection class.

De ovennævnte krav er vanskelige at opfylde samtidigt. Det er specielt vanskeligt at tilvejebringe en kapsling, som er drypvandsbe-skyttende ifølge krav a og samtidig giver god ventilation ifølge krav b.The above requirements are difficult to fulfill at the same time. It is particularly difficult to provide a housing which is drip-water resistant according to claim a and at the same time provides good ventilation according to claim b.

20 Kapslingen ifølge opfindelsen er af den art, som omfatter en bageste kapslingsdel bestemt til montering mod en væg eller et gulv samt en til den bageste,, kaplingsdel fikseret forreste kapslingsdel, hvor mod hinanden grænsende kantpartier af de forskellige kapslingsdele er vinkelformede, for eksempel som et L, U eller Z til dannelse af en 25 drypvandsbeskyttende overlapningssamling, som har et udad åbent spor (i princippet som vist i svensk fremlæggelsesskrift nr. 42066¾.The housing according to the invention is of the kind comprising a rear housing part intended for mounting against a wall or floor and a front housing housing fixed to the rear housing, where adjacent edge portions of the various housing parts are angular, for example as an L, U or Z to form a drip-water protective overlap assembly having an outwardly open groove (in principle, as shown in Swedish Patent Specification No. 42066¾).

Ved en sådan kapsling kan man få de ovennævnte krav opfyldt, ved at kapslingen ifølge opfindelsen gives de i den kendetegnende del af patentkrav 1 angivne særlige træk. Ved denne udførelse opnås, 30 at man let kan anbringe en mod dryppende vand beskyttet udstrøm-ningsibning for ventilationsluften i tilslutning til den over den bageste kaplingsdel dannede lomme.In such a housing, the above-mentioned requirements can be fulfilled by giving the housing according to the invention the special features specified in the characterizing part of claim 1. In this embodiment, it is achieved that one can easily place an outflow opening protected against dripping water for the ventilation air in connection with the pocket formed over the rear housing part.

Ved en særlig hensigtsmæssig udførelsesform for opfindelsen er den bageste kapslingsdel i det mindste over en del af sin højde 35 kileformet tilspidsende opad. Delingssporet, mellem den bageste og forreste kapslingsdels sideflader vil derved få en hældning i retning udad-nedad fra kapslingens lodrette bagside. Derved opnås bedre beskyttelse mod indtrængning af vand.In a particularly convenient embodiment of the invention, the rear housing portion is at least above a portion of its height 35 wedge-shaped tapered upwardly. The splitting groove, between the rear and front casing portion side faces, will thereby incline outwardly downward from the vertical rear face of the casing. This provides better protection against water ingress.

3 11, som er fastmonteret pi en væg 10, samt en til den bageste kapslingsdel fikseret forreste kapslingsdel, som i det viste udførelseseksempel består af en øvre del 21 og en nedre del 22. Den forreste kapslingsdels øvre del 21 strækker sig højere op end den bageste 5 kapslingsdel 11, hvorved der dannes en rendeformet lomme 30 mellem kapslingsdelen 21 og væggen 10.3 11, which is fixedly mounted on a wall 10, as well as a front housing portion fixed to the rear housing portion, which in the illustrated embodiment consists of an upper portion 21 and a lower portion 22. The upper housing portion 21 extends higher than the upper housing portion 21. rear 5 housing 11, thereby forming a gutter pocket 30 between housing 21 and wall 10.

Kapslingsdelen 21 er svingeligt ophængt i et lejringssted 31 (fig. 3) ved den øverste kant af den bageste kapslingsdel og kan svinges op og eventuelt løftes af ved inspektion og service.The enclosure member 21 is pivotally suspended in a bearing location 31 (Fig. 3) at the upper edge of the rear enclosure member and can be swung up and possibly lifted off by inspection and service.

10 Efter at den øverste kapslingsdel 21 er svinget op, kan den nederste kapslingsdel 22 svinges ned til den i fig. 3 viste stilling, hvor kapslingsdelen 22 hænger i et til den bageste kapslingsdel 11 fikseret bind 32. Derved opnås god tilgængelighed for det i kapslingen monterede materiel. Fig. 8 viser et eksempel pi en apparatbe-15 stykning med to elektronikenheder 33,34, et strømforsyningsorgan 35, en klemrække 36 og eksterne tilslutningskabler 37. Den ene elektronikenhed 34, der er monteret foran den anden elektronikenhed 33, er nedfældelig til den i fig. 3 viste stilling, hvorved også den bagved liggende enhed 33 er tilgængelig for service.10 After the upper casing portion 21 is swung up, the lower casing portion 22 can be pivoted down to the one shown in FIG. 3, where the casing part 22 hangs in a tie 32 fixed to the rear casing part 11. This provides good accessibility for the material mounted in the casing. FIG. 8 shows an example of an apparatus piece with two electronics units 33,34, a power supply means 35, a terminal block 36 and external connection cables 37. One electronics unit 34 mounted in front of the other electronics unit 33 is foldable to the one shown in FIG. 3, whereby the underlying unit 33 is also available for service.

20 Også i den forreste kapslingsdel kan der anbringes apparater, såsom manøvre- og indikeringsorganer. Til visse udrustninger kan det endvidere være hensigtsmæssigt, at den øverste kaplingsdel er forsynet med et indspektionsvindue.Apparatus, such as maneuvering and indicating means, may also be placed in the front housing. In addition, for some equipment, it may be appropriate that the upper housing portion be provided with an inspection window.

Fig. 4-7 viser forskellige varianter af den ovenfor beskrevne 25 kapslingstype. Fig. 4 og 5 viser eksempler på kapslinger, hvor den øverste og nederste del af kapslingen har forskellige dybdemål for tilpasning til de apparater, som skal placeres i kapslingen. Fig. 6 viser en udførelse, hvor den forreste kapslingsdel er udelt. Fig. 7 viser en udførelse, hvor delelinien 18 mellem den bageste kapslings-30 del 11 og de forreste kapslingsdele 21,22 er brudt.FIG. 4-7 show various variants of the enclosure type described above. FIG. 4 and 5 show examples of enclosures in which the upper and lower portions of the enclosure have different depth dimensions for adapting to the appliances to be placed in the enclosure. FIG. 6 shows an embodiment in which the front housing portion is distributed. FIG. 7 shows an embodiment in which the dividing line 18 between the rear casing part 11 and the front casing parts 21,22 is broken.

Delesporet 19 mellem sidefladerne af kapslingsdelene 21 og 22 behøver ikke at være horisontalt, idet vinklen β (i fig. 4) mellem delesporene 18 og 19 kan variere inden for vide grænser.The dividing groove 19 between the side surfaces of the housing portions 21 and 22 need not be horizontal, since the angle β (in Fig. 4) between the dividing grooves 18 and 19 can vary within wide limits.

Ved de i fig. 1-8 viste udførelsesformer er den bageste kaps-35 lingsdel 11 i det mindste på en del af sin højde kileformet tilspidsende opad. Derved vil delesporet 18 mellem sidefladerne af den bageste kapslingsdel 11 og den forreste kapslingsdel 21,22 hælde udad-nedad fra kapslingens lodrette bagside. I de viste udførelseseksempler er vinklen a (i fig. 4) mellem delesporet og den lodrette linie 15°, menIn the FIG. 1-8, the rear casing portion 11 is at least part of its height wedge-shaped tapered upward. Thereby, the dividing groove 18 between the side surfaces of the rear casing portion 11 and the front casing portion 21.22 will incline outwardly from the vertical rear face of the casing. In the illustrated embodiments, the angle α (in Fig. 4) between the dividing groove and the vertical line is 15 °, but

DK 158436 BDK 158436 B

4 denne vinkel kan i princippet have en hvilken som helst anden værdi, fortrinsvis dog ikke overstigende 45°. Ved delesporets hældning opnås bedre beskyttelse mod indtrægning af vand, hvorved denne kapslings samling også kan udføres uden pakning for tilveje-5 bringelse af bedre ventilation.4 this angle may in principle have any other value, preferably not exceeding 45 °. The slope of the dividing track provides better protection against water ingress, whereby the assembly of this housing can also be carried out without a gasket to provide better ventilation.

Mod hinanden grænsende kantpartier af de forskellige kapslings-dele er vinkelformede, for eksempel som et L, U eller Z, og kaps-lingssamlingerne er udført således, at den øverste kapslingsdel "lapper over" den nedre. Derved fås en drypvandsbeskyttende 10 samling, som samtidig tillader god ventilation. Hvis der i stedet ønskes en helt tæt samling, kan denne udføres i henhold til fig. 9, som viser et tværsnit gennem en sådan samling mellem en øverste kapslingdel 22 og en nederste kapslingsdel 11, hvor en pakning 40 er anbragt mellem kapslingsdelene. For denne type af samlinger med 15 eller uden pakning er det karakterisktisk, at de har et udad åbent spor (for eksempel sporene 18,19).Adjacent edge portions of the various enclosure portions are angular, for example, as an L, U or Z, and the enclosure assemblies are designed so that the upper enclosure portion "overlaps" the lower one. Thereby, a drip-water-resistant joint is obtained which at the same time allows good ventilation. If a completely dense joint is desired instead, this can be carried out according to FIG. 9, which shows a cross section through such an assembly between an upper housing portion 22 and a lower housing portion 11, where a gasket 40 is disposed between the housing portions. For this type of joints with 15 or without gasket, it is characteristic that they have an outwardly open groove (for example, grooves 18,19).

I fig. 4 viser pilene A og B, hvorledes ventilationsluften strømmer ind i henholdsvis ud af kapslingen.Køleluften strømmer ind gennem en med insektbeskyttelse, for eksempel et finmasket net, 20 forsynet ventilationsåbning i den bageste kapslingsdels bundplade 13, der er forsænket for at give drypkant og plads for et eventuelt filter. Også spalten i den vandrette kapslingssamling 17 på kapslingens nedadvendende side kan anvendes til køleluftindtag. Udstrømningen sker opadtil fra den forreste kapslingsdel 21 gennem en 25 åbning 29 (fig. 10) til lommen 30, i hvilken insektbeskyttelse og et eventuelt filter anbringes.In FIG. 4 shows the arrows A and B, how the ventilation air flows into and out of the housing, respectively. for a possible filter. Also, the slot in the horizontal casing assembly 17 on the downward facing side of the casing can be used for cooling air intake. Outflow occurs upwardly from the front casing portion 21 through an opening 29 (Fig. 10) to the pocket 30 into which insect protection and an optional filter are placed.

I de tilfælde, hvor luftgennemstrømning ikke kræves, og hvor man vil have en helt tæt kapsling, udføres detaljen X i fig. 5 med pakningen 40, som vist i fig. 11.In those cases where air flow is not required and where a very dense enclosure is desired, the detail X in FIG. 5 with the gasket 40, as shown in FIG. 11th

30 Den bageste kapslingsdels tag- og bundplader 12 henholdsvis 13 rager ud på bagsiden af rygpladen 14 (fig. 11), hvorved kapslingens bagside får afstand fra væggen. Derved fås en ventilationsspalter 28 mellem væggen og rygpladen, hvilket forbedrer kølingen.The roof and bottom plates 12 and 13 respectively of the rear housing portion protrude on the back of the back plate 14 (Fig. 11), thereby leaving the back of the housing away from the wall. This provides a ventilation gap 28 between the wall and the back plate, which improves cooling.

I fig. 12-14 er vist en udførelse af en kapsling, hvor den 35 bageste kapslingsdel 11 udgøres af en bærende ramme udført af stål eller strengpresset i aluminium eller plast. Denne konstruktion er egnet til større kapslinger med relativt tung apparatbestykning.In FIG. 12-14, an embodiment of a housing is shown in which the rear casing part 11 is constituted by a support frame made of steel or extruded in aluminum or plastic. This construction is suitable for larger enclosures with relatively heavy device casting.

Rammen er forsynet med to vandrette på hvert sit rammesidestykke i samme højde anbragte bærearme 15, der kan være placeret i forskelli-The frame is provided with two horizontal support arms 15 arranged on each of its frame side pieces, which can be placed in different shapes.

I den 5 nederste del af kapslingen findes der en strømretter 41, medens en tilhørende rammekonstruktion 42 er anbragt i den øverste del af kapslingen. Rammekonstruktionen er let tilgængelig for service efter opsvingnmg af hætten 21, hvorefter også lågen 23 kan svinges ned, hvis strømretteren skal tilses.5 ge height positions on the frame. In addition, the support arms may be joined by a transverse beam. The front portion of the housing is constituted by a swiveling cap 21 disposed above the support arms 15 and a cap 22 with a cover 23 disposed below the support arms. In the lower part of the housing there is a rectifier 41, while an associated frame structure 42 is arranged in the upper part. of the housing. The frame structure is readily available for service after the cap 21 has been swung up, after which the lid 23 can also be swung down if the inverter is to be fitted.

10 Fig. 15 og 16 viser to varianter af samme type af rammebaseret kapsling, som beskrevet ovenfor i forbindelse med fig, 12-14. Udførelsen i fig. 15 adskiller sig fra den i fig. 12 viste ved, at den nederste kapslingsdel 22 udgøres af en hel afløftelig kappe uden låge. Ved udførelsen i fig. 16 er bærearmene 15 anbragt ved den 15 nederste ende af rammens sidestykker, og den forreste kapslingsdel 21 udgøres af en enkelt opsvingelig og afløftelig hætte. I visse tilfælde kan det ved en kapsling af den udførelse, som er vist i fig.FIG. 15 and 16 show two variants of the same type of frame-based enclosure, as described above in connection with Figs. 12-14. The embodiment of FIG. 15 differs from that of FIG. 12 shows that the lower housing portion 22 is made up of a fully removable cover without a door. In the embodiment of FIG. 16, the support arms 15 are positioned at the lower end of the frame side members, and the front casing portion 21 is constituted by a single retractable and removable cap.
