Ingeniørfirmaet Budde, Schou & Co._' _ ~ (54) Smeltesikringshus.Ingeniørfirmaet Budde, Schou & Co._ '_ ~ (54) Smeltesikringshus.

Smeltesikringshus til anbringelse af et antal sikringspropper af diazedtype, som omfatter en bunddel og en på bunddelen drejeligt monteret betjeningsklap, ved hjælp af hvilken huset kan indtage åben og lukket stilling, hvor betjeningsklappen er udformet som en åben æske, i hvilken sikringspropperne er anbragt ved hjælp af en holder og som, når huset er lukket giver kontakt til en til hver sikringsprop hørende strømførende kontaktskinne, der er anbragt i bunddelen.Melting fuse housing for mounting a number of diazed-type fuse plugs, which comprise a bottom part and a control flap rotatably mounted on the bottom part, by means of which the housing can assume an open and closed position, the control flap being formed as an open box in which the fuse plugs are arranged by means of a holder and which, when the housing is closed, provides contact to a live contact rail belonging to each fuse plug, which is arranged in the bottom part.

I kabelskabe anvendes for tiden enkelte sikringer bestående af smeltepropper, som holdes på plads ved hjælp af en gevindhætte. Ved udskiftning af en smeltet sikringsprop må hætten skrues af og proppen tillige fjernes, hvorved spændings- 2 142434 førende dele i kabelskabet delvis fritlægges. Derved opstår der en fare for berøring af spændingsførende dele. Anvendelse af en gevindhætte som holder for smeltepropper kan endvidere indebære risiko for, at hætten under visse forhold utilsigtet skrues af med påfølgende kontaktafbrydelse og driftsforstyrrelse til følge.In cable cabinets, individual fuses consisting of fuse plugs are currently used, which are held in place by means of a threaded cap. When replacing a molten fuse plug, the cap must be unscrewed and the plug also removed, thereby partially releasing live parts in the cable cabinet. This creates a danger of contact with live parts. The use of a threaded cap as a holder for fuses can also entail a risk that the cap will inadvertently be unscrewed under certain conditions, with consequent disconnection and operational disturbance as a result.

Formålet med opfindelsen er at fremstille et hus til et antal sikringspropper, som, samtidigt med at en kompakt og pladsbesparende udformning bevares, eliminerer risikoen for berøring af spændingsførende dele ved udskiftning af en eller flere propper. Dette opnås ved den i krav 1 angivne konstruktion.The object of the invention is to manufacture a housing for a number of safety plugs which, while maintaining a compact and space-saving design, eliminates the risk of contact with live parts when replacing one or more plugs. This is achieved by the construction specified in claim 1.

Opfindelsen skal nu forklares nærmere under henvisning til vedlagte tegninger, hvor fig. 1 viser huset ifølge opfindelsen delvis i et længdesnit, fig. 2 viser set ovenfra og i lukket stilling en del af bundpladen i huset, fig. 3 viser husets betjeningsklap set nedefra, fig. 4 viser nærmere udseendet af en slæde, som indgår i huset.The invention will now be explained in more detail with reference to the accompanying drawings, in which fig. 1 shows the housing according to the invention partly in a longitudinal section, fig. 2 shows a top view and in closed position a part of the bottom plate in the housing, fig. 3 shows the control flap of the housing seen from below, fig. 4 shows in more detail the appearance of a sledge which is part of the housing.

I fig. 1 betegner 1 husets bundplade og 2 dets betjeningsklap, som ved hjælp af akselen 2a er drejeligt lejret på lejeholderen la, som udgør en del af bundpladen 1. Et håndtag 3 er drejeligt lejret ved hjælp af en stift 12 på betjeningsklappen 2 og har et anlæg 3a, der i husets lukkede tilstand som vist på tegningen låser en fjederbøjle 6. Når håndtaget 3 føres opad, som det er antydet med pilen a, går den del af fjederbøjlen, der ligger an mod anlægget 3a, efterhånden fri af sit leje og kan føres over anlægget og videre over den på tegningen viste højre kant af betjeningsklappen 2, hvorved huset kan åbnes, ved at klappen 2 nu kan løftes fra bundpladen 1 og drejes omkring akselen 2a sådan som antydet med pilen b.In FIG. 1 denotes 1 the bottom plate of the housing and 2 its control flap, which by means of the shaft 2a is rotatably mounted on the bearing holder 1a, which forms part of the bottom plate 1. A handle 3 is rotatably mounted by means of a pin 12 on the control flap 2 and has an abutment 3a, which in the closed condition of the housing, as shown in the drawing, locks a spring bracket 6. When the handle 3 is moved upwards, as indicated by the arrow a, the part of the spring bracket which abuts the system 3a gradually becomes free of its bearing and can is passed over the system and further over the right edge of the control flap 2 shown in the drawing, whereby the housing can be opened, in that the flap 2 can now be lifted from the bottom plate 1 and rotated about the shaft 2a as indicated by the arrow b.

Den i fig. 1 viste udformning af huset er beregnet til at fastholde tre sikringspropper af hvilke den ene, betegnet 4, er vist på tegningen. Proppen 4 holdes, når huset er lukket, på plads dels ved hjælp af en holder 7 af i og for sig kendt udseende, dels ved hjælp af et støtteorgan 15, der befinder sig på begge sider af proppen, og hvis udseende vil fremgå nærmere af fig. 3. Holderens 7 øverste plane og cirkulære del 7a udgør en kontaktdel og ligger an mod proppens bagerste bundflade, og 142434 3 dens øverste del er udformet med et gribeorgan 7b, som ligger an mod proppens cylindriske overflade. 7c betegner holderens tilslutningsdel til et kabel 11 til tilslutning til en forbruger. Kontaktdelen 7a er fastholdt af den ene ende af en trykfjeder 8, hvis anden ende er anbragt i fjederkonsollen 2b, som danner et udskydende parti på betjeningsklappens overside. Fjederkonsollen 2b har et hul 2c med beskyttelsesglas til inspektion af proppens tilstand.The device shown in FIG. 1 is intended to hold three safety plugs, one of which, designated 4, is shown in the drawing. The plug 4 is held, when the housing is closed, partly by means of a holder 7 of a per se known appearance, partly by means of a support member 15, which is located on both sides of the plug, and whose appearance will appear more closely from fig. The upper plane and circular part 7a of the holder 7 constitutes a contact part and abuts against the rear bottom surface of the plug, and its upper part is formed with a gripping member 7b which abuts against the cylindrical surface of the plug. 7c denotes the connection part of the holder to a cable 11 for connection to a consumer. The contact part 7a is held by one end of a compression spring 8, the other end of which is arranged in the spring bracket 2b, which forms a projecting portion on the upper side of the control flap. The spring bracket 2b has a hole 2c with protective glass for inspecting the condition of the plug.

Bundpladen 1 består, som det bedst fremgår af fig, 2, af en plan horisontal del la, som til siderne begrænses af to opretstående vægge lb og lc. Bundpladen 1 er udformet med en hul fod ld til montering af en ikke vist fastspændingsskrue, som går gennem et hul le. Fastspændingsskruen er beregnet til at fastholde bundpladen til et fast underlagt hvis man vil fastholde kabelskabets skinnesystem ved hjælp af huset. Ved hvert tilslutningssted er bundpladens vægge lb og lc udformet med en flange lf til styring af en slæde 5, hvis udseende og funktion vil blive beskrevet nærmere nedenfor. På flangen lf er der en knast lg til styring af betjeningsklappen 2, når huset skal indtage lukket stilling. Bundpladen er endvidere udformet med en retangulær åbning lh for at give plads dels' til en skrue 10, dels til en jævntyk kontaktskinne 9. Skruen 10 har til opgave at fastspænde skinnen 9 til kabelskabets faseskinne og i en udskæring 9a i denne er anbragt en afbrydningsfjeder 13 for lysbue. Afbrydningsfjederens 13 fjedrende del er anbragt i en bro 14, som desuden danner støtte for kontaktskinnen 9. -The bottom plate 1 consists, as best seen in Fig. 2, of a planar horizontal part 1a, which is bounded on the sides by two upright walls 1b and 1c. The base plate 1 is formed with a hollow foot ld for mounting a clamping screw (not shown) which passes through a hollow le. The clamping screw is intended to hold the base plate to a fixed base if you want to hold the cable cabinet rail system by means of the housing. At each connection point, the walls 1b and 1c of the base plate are formed with a flange 1f for guiding a carriage 5, the appearance and function of which will be described in more detail below. On the flange 1f there is a cam lug for controlling the control flap 2 when the housing is to assume the closed position. The base plate is further formed with a retangular opening 1h to make room partly 'for a screw 10, partly for an evenly thick contact rail 9. The screw 10 has the task of clamping the rail 9 to the phase rail of the cable cabinet and in a cut-out 9a in it a disconnecting spring is arranged 13 for arc. The resilient part of the cut-off spring 13 is arranged in a bridge 14, which also forms a support for the contact rail 9. -

Fig. 3 viser betjeningsklappen set nedefra. I dens bund dvs. på undersiden af dens øvre plane overflade, er der, som beskrevet i forbindelse med fig. 1, en cirkulær fatning ,2b, der er udformet til at indeholde trykfjederen S. Desuden er vist det ovenfor nævnte inspektionshul 2c. En sikringsprop, hvis cylindriske ydre kontur er antydet med 4, er placeret i den ikke viste holder 7 ifølge fig. 1. Mellem hver props placering er der anbragt et støtteorgan 15, som består af et tyndt skelet 15a og af en grovere udskudt del 15b. Støtteorganet har til opgave at støtte den indsatte sikringsprop 4.FIG. 3 shows the control flap seen from below. At its bottom i.e. on the underside of its upper planar surface, as described in connection with FIG. 1, a circular socket, 2b, which is designed to contain the compression spring S. In addition, the above-mentioned inspection hole 2c is shown. A fuse plug, the cylindrical outer contour of which is indicated by 4, is located in the holder 7 not shown according to fig. Arranged between the location of each plug is a support member 15, which consists of a thin skeleton 15a and of a coarser projecting part 15b. The task of the support body is to support the inserted safety plug 4.

Fig. 4 viser et tværsnit langs den stiplede linie A - A i fig. 3 for nærmere at anskueliggøre støtteorganet 15's udformning i betjeningsklappen 2.FIG. 4 shows a cross section along the dotted line A - A in fig. 3 in order to illustrate in more detail the design of the support member 15 in the control flap 2.

4 1424344 142434

Bredden af betjeningsklappen, dvs- afstanden d mellem dens indervægge, er valgt under hensyn til diameterdimensionen på den anvendte sikringsprop og under hensyn til at give tilstrækkelig plads til gribeorganet 7b på holderen 7. Herved kan der spares plads i sammenligning med en sikringsliste, hvor sikringspropperne indsættes med f.eks. en gevindhætte for samme antal propper.The width of the control flap, i.e. the distance d between its inner walls, is chosen taking into account the diameter dimension of the securing plug used and taking into account sufficient space for the gripping member 7b on the holder 7. This can save space in comparison with a securing strip where the securing plugs inserted with e.g. a threaded cap for the same number of plugs.

Med henblik at gøre huset berøringssikkert er en bevægelig slæde 5 anbragt på bundpladen 1. Slæden, hvis udseende fremgår nærmere af fig. 5, er forsynet med et antal cirkulære huller 5a svarende til antallet af sikringspropper- Diameteren på et hul er valgt under hensyn til diameteren på den sikringsprop, der har højst tilladte mærkestrøm. Som det også fremgår af fig. 1 er slæden i den ene ende udformet med en knast 5b, der på sin side er udformet som en sporkurve 5c. Forneden og lagt an på sporkurven er anbragt en medbringer 5e fra betjeningsklappen 2. Når klappen 2 åbner huset i retning efter pil b, kommer medbringeren 5e til at glide ud ad kurven 5c og slæden 5 bliver forskudt efter pilen c. Dette medfører at hullet 5a forskydes så skinnen 9 bliver helt dækket af slæden, hvorved skinnen bliver utilgængelig når en prop eventuelt skal fjernes fra sin holder 7 i betjeningsklappen 2. Slæden udfører således, når huset åbnes, en langsgående bevægelse, og dækker i åben stilling de spændingsførende dele. Hullerne 5a i slæden 5 udformes hensigtsmæssigt sådan at de får samme funktion som paskontakterne i sikringspropper, dvs. forhindrer anvendelse af en for stor sikring med højere mærkestrøm end tilladt.In order to make the housing contact-proof, a movable carriage 5 is arranged on the bottom plate 1. The carriage, the appearance of which is shown in more detail in fig. 5, is provided with a number of circular holes 5a corresponding to the number of fuse plugs. The diameter of a hole is selected taking into account the diameter of the fuse plug which has the maximum permissible rated current. As can also be seen from FIG. 1, the carriage is formed at one end with a cam 5b, which in turn is designed as a track curve 5c. At the bottom and placed on the track basket is a carrier 5e from the control flap 2. When the flap 2 opens the housing in the direction of arrow b, the carrier 5e slides out of the basket 5c and the carriage 5 is displaced after the arrow c. This causes the hole 5a is displaced so that the rail 9 is completely covered by the carriage, whereby the rail becomes inaccessible when a plug may have to be removed from its holder 7 in the control flap 2. Thus, when the housing is opened, the carriage performs a longitudinal movement and covers the live parts in open position. The holes 5a in the carriage 5 are suitably designed so that they have the same function as the fitting contacts in securing plugs, i.e. prevents the use of an excessive fuse with a higher rated current than permitted.

På skruen 10 undet husets bundplade er der hensigtsmæssigt fastskruet en metaldel, som har plan underside og som når huset monteres til kabelskabet giver kontakt til dettes skinne. Denne elektriske forbindelse kan også tjene til mekanisk fastholdelse af huset.On the screw 10 without the bottom plate of the housing, a metal part is suitably screwed, which has a flat underside and which, when the housing is mounted to the cable cabinet, provides contact to its rail. This electrical connection can also serve for mechanical maintenance of the housing.

Håndtaget 3 er ved anlægget 3a hensigtsmæssigt udformet med en ekscentrisk virkning, således at låsningen af betjeningsklappen til bundpladen sker som en kombination af en snaplås og en ekscenterlås.The handle 3 at the abutment 3a is suitably designed with an eccentric effect, so that the locking of the control flap to the bottom plate takes place as a combination of a snap lock and an eccentric lock.

Når sikringspropperne skal anbringes i huset, åbnes dette, hvorved slæden 5 forskydes, så at den i husets åbne stilling dækker de strømførende dele (kontaktskinnen 9). Hver prop anbringes, sådan som det fremgår af fig. 1, dvs. med den del, der har den største cylinderdiameter i holderen 7, hvorved proppen 142434 5 holdes på plads ved hjælp af støtteorganet 15 på begge sider. Derefter lukkes huset ved at betjeningsklappen 2 lukkes ned mod bundpladen 1, og huset låses i sin lukkede stilling med håndtaget 3, sådan som det er beskrevet ovenfor. Når huset lukkes bliver kontaktfjedrene derved sammenpressede og et godt kontakttryk sikres for propperne. Hvis sikringsproppen er brændt fast på kontaktskinnen 9, påvirker den bevægelige slæde 5 proppen i tværretningen, når huset åbnes, så proppen løsnes.When the fuse plugs are to be placed in the housing, this is opened, whereby the slide 5 is displaced so that in the open position of the housing it covers the live parts (contact rail 9). Each plug is placed as shown in FIG. 1, i.e. with the part having the largest cylinder diameter in the holder 7, whereby the plug 142434 5 is held in place by the support means 15 on both sides. Then the housing is closed by closing the control flap 2 against the bottom plate 1, and the housing is locked in its closed position with the handle 3, as described above. When the housing is closed, the contact springs are thereby compressed and a good contact pressure is ensured for the plugs. If the safety plug is burned onto the contact rail 9, the movable carriage 5 acts on the plug in the transverse direction when the housing is opened, so that the plug is loosened.

Huset består fortrinsvis af et syntetisk materiale med god styrke og temperaturbestandighed, f.eks. glasfiberarmeret polyester.The housing preferably consists of a synthetic material with good strength and temperature resistance, e.g. fiberglass-reinforced polyester.

Det foreslåede hus er først og fremmest beregnet til at indeholde tre sikringspfopper til en trefaseforbruger, men kan givetvis også udformes til et kabelskab med et større antal propper til enfaseforbrugere.The proposed housing is primarily intended to contain three fuse pops for a three-phase consumer, but can of course also be designed for a cable cabinet with a larger number of plugs for single-phase consumers.
