Abstract

Installations boxes of the type that have means for connecting together two of more boxes and are intended to be recessed into walls are provided with circular stubs 11, 12 and 13 respectively pointing in opposite directions for receiving electrical leads, which stubs are oriented in line with or close to the bottom part of the box, however in such a way that the distance x from the upper surface of the stub or stubs to the upper edge part of the box constitutes a previously determined first distance. According to the invention, an essential characteristic thereof is that at least one first part 15, and 18, 19 respectively running in a horizontal direction and shaped as a shank, interacting with at least one part of at least one stub 13 and 11, 12 respectively, and of a second part 16 and 21 respectively, the surface of which that adjoins the shank 15 or the shanks 18, 19 interacts with a stub 13 or stubs 11, 12 essentially in a vertical plane and the opposite surface of which forms one limit plane for a second distance y, the second limit plane being formed in a known way by the front edge of the box. <IMAGE>

Description

82057111 'ES 10 15 20 25 30 och som skänkel utformad första del samverkande med åtmins- tone en del av åtminstone en rörstuts, samt av en andra del vars till skänkel eller skänklarna anslutande yta samver- kar med en rörstuts eller rörstutsar väsentligen i ett ver- tikalplan och vars motsatta yta utgör det ena begränsnings- planet för ett andra avstånd varvid det andra begränsnings- planet på i och för sig känt sätt bildas av dosans främre kant. Genom att rörstutsarna oavsett väggtjocklek oriente- ras nära dosans botten inses att utrymmet för kopplings- plintar inuti dosan alltid optimeras. 82057111 'ES 10 15 20 25 30 and as a leg shaped first part cooperating with at least tone part of at least one pipe socket, as well as of a second part whose surface joins the leg or legs together with a pipe fitting or pipe fittings essentially in a technical plane and whose opposite surface constitutes one of the plane for a second distance, the second limiting the plane in a manner known per se is formed by the front of the box edge. By orienting the pipe fittings regardless of wall thickness, near the bottom of the box it will be appreciated that the space for terminals inside the box are always optimized.

Beskrivning Uppfinningen kommer nedan närmare att förklaras i anslut- ning till bifogade ritning som visar en som exempel vald utföringsform. På ritningen visar fig. 1'en sidovy av en elektrisk installationsdoea, fig. 2 visar dosans motsatta sida och fig._3 är en ovanvy av dosan enligt fig. 1 och 2.Description The invention will be explained in more detail below in connection with to the accompanying drawing showing an example selected embodiment. In the drawing shows Fig. 1 is a side view of an electrical installation device; Fig. 2 shows the opposite side of the box and Fig. 3 is a plan view of the box of Figs. 1 and 2.

I samtliga figurer är den med heldragna linjer visade instal- lationsdosan förbunden eller förbindbar med en, med streck- prickade linjer blott antydd identisk dosa.In all figures, the installation shown in solid lines is the connection box is connected or connectable to a dotted lines merely hinted at identical box.

Föredraget utföringsexempel Den på ritningen visade kopplingdosan uppvisar en åt ett håll riktad rörstuts och två åt motsatt håll riktade rör- stutsar, men det inses, att antalet rörstutsar kan variera.Preferred embodiment The junction box shown in the drawing has one at a time directional pipe fittings and two opposite pipe fittings stubs, but it will be appreciated that the number of pipe stubs may vary.

En vanlig apparatdcsa har dock normalt tre stutsar, således i enlighet med utföringsexemplet.An ordinary appliance dcsa, however, normally has three sockets, thus in accordance with the working example.

Den visade inštallationsdosan är till sin allmäna ubpbygg- nad väl känd och framställd av formsprutad polyeten eller polyamid. Den har en mantelyta 10 som kan vara slät eller försedd med en eller flera rillor. Ett antal i varandra mot- satta riktningar förlöpande rörstutsar 11; 12, 13 är anord- nade att upptaga icke visade s.k. VP-rör vari elektriska ledningar härbärgeras. Stutsarna 11, 12, 13 är så oriente- 15 20 25 30 8205741-"5 rade att sträckan x från stutsens eller stutsarnas övre yta till dosans framkant utgör ett på förhand bestämt förs- ta avstånd. Vanligen innebär detta att rörstutsarnas undre sektor 11, 12, 13 ligger i flukt med eller nära dosans bot- ten. I ungefär 900 relativt stutsarnas längdriktning finns förbindningsorgan 14 som användes att sammankoppla en dosa med en annan.The installation box shown is for its general construction well known and made of injection molded polyethylene or polyamide. It has a mantle surface 10 which can be smooth or provided with one or more grooves. A number of set directions extending pipe sockets 11; 12, 13 are arranged nade to record not shown so-called VP pipes in which electric wires are housed. The nozzles 11, 12, 13 are so oriented 15 20 25 30 8205741- "5 that the distance x from the top of the nozzle or nozzles surface to the leading edge of the box constitutes a predetermined dissociate. Usually this means the lower of the pipe fittings sectors 11, 12, 13 are in line with or close to the bottom of the box. ten. In about 900 relative to the longitudinal direction of the stubs there are connector 14 used to interconnect a box with another.

För att kunna anpassa tvâ eller flera med varandra samman- kopplade dosor anvisas enligt det valda utföringsexenmlet tvâ olika anordningar i beroende av om antalet rörstutsar är en eller flera än en.In order to be able to align two or more with each other coupled boxes are indicated according to the selected embodiment two different devices depending on the number of pipe fittings is one or more than one.

I fig. 1 visas exemplet med tvâ bredvid, men på något radi- ellt avstånd från varandra anordnade rörstutsar 11, 12. Den nya anordningen består här av en första del, utformad som en horisontellt förlöpande skänkel 15 samt en till ena skän- keländen sig anslutande andra del 16.Fig. 1 shows the example with two next to it, but on some spaced apart pipe fittings 11, 12. The the new device here consists of a first part, designed as a horizontally extending leg 15 and one to one leg keländen sig connecting second part 16.

Skänkeln 15är med presspassning införd mellan rörstutsarna 11, 12 och företrädesvis är åtminstone en del av skänkelns 15 mot rörstutsarna 11, 12 anliqgande ytor komplementära till rörstutsen. Den andra delen 16 är ungefär i centrum ansluten till skänkeldelen 15 och anordnad att anligga mot den övre ytan av åtminstone två närliggande rörstutsar. De- len 16 har en sådan axiell utbredning att den anligger mot övre ytan av åtminstone två närliggande rörstutsar och dess övre yta utgör det ena begränsningsplanet för ett andra av- stånd y varvid nämnda andra avstânds andra begränsningsplan på känt'sätt bildas av dosans främre kant. Skänkelns 15 fria ände kan även anligga mot ansatsen 17. Anordningen 15, 16 är framställd som en enhet. Det inses också, att de ut- rymmen mellan delarna 15 och 16 vilka begränsas av en cirkel- sektor av rörstutsarna 11, 12 kan utfyllas och således bil- da del av anordningen. 4.The leg 15 is inserted between the pipe fittings with a press fit 11, 12 and preferably is at least a part of the leg Surfaces adjacent to the pipe fittings 11, 12 are complementary to the pipe socket. The second part 16 is approximately in the center connected to the leg part 15 and arranged to abut against the upper surface of at least two adjacent pipe sockets. The- The shaft 16 has such an axial extension that it abuts against upper surface of at least two adjacent pipe fittings and its upper surface constitutes one boundary plane for a second position y wherein said second distance is the second boundary plane in a known manner formed by the leading edge of the box. The leg 15 free end can also abut against the shoulder 17. The device 15, 16 is made as a unit. It is also recognized that the the space between the parts 15 and 16 which are limited by a circular sector of the pipe fittings 11, 12 can be filled in and thus then part of the device. 4.
