Abstract

A terminal or junction box specially designed to be inset in a wall consists of a circular shell (10) to which both a bottom section (11) and a number of connecting pieces (12), which are positioned at a certain distance from the front edge of the box, connect. In this invention, the free lateral area (11) of the box is designed to detachably house a ring (13), which is preferably equipped with nail guides. The use of said ring allows box installation to be adapted to one of two wall thicknesses.<IMAGE>

Description

15 20 25 30 8Û02926-7 Dosan uppåt vända del är öppen. Ett antal i motsatta rikt- ningar förlöpande stutsar 12 är på känt sätt anordnade att upptaga icke visade ledningar och dessa stutsar är orienterade på ett på förhand bestämt avstånd från dosans främre kant 13 och detta avstånd a (mantelns fria yta) svarar mot dosans korrekta infästning i en vägg bestående av ett antal skivor av det material som används, exempel- vis med en total tjocklek av 26 mm. 15 20 25 30 8Û02926-7 The box facing upwards is open. A number of sockets 12 extending in opposite directions are arranged in a known manner to receive wires (not shown) and these sockets are oriented at a predetermined distance from the front edge 13 of the box and this distance a (free surface of the jacket) corresponds to the correct attachment of the box. in a wall consisting of a number of boards of the material used, for example with a total thickness of 26 mm.

Den uppfinningsenliga dosan uppvisar en ring 13 med åtmin- stone två spår 14 som i ett läge samverkar med styrpinnar 15 i dosans fria mantelparti. Ringen 13 kan därigenom lös- tagbart bringas att samverka med mantelytan 10 och ringens undre parti anligger mot stutsarnas 12 övre del.The box according to the invention has a ring 13 with at least two grooves 14 which in one position cooperate with guide pins 15 in the free jacket portion of the box. The ring 13 can thereby be releasably caused to co-operate with the mantle surface 10 and the lower part of the ring abuts against the upper part of the stubs 12.

Genom att vrida ringen 13 till det läge, som antydes ge- nom streckmarkeringar i fig.1 bibringas den en låsning mot axiell förskjutning relativt dosan och mantelytans fria parti har därigenom samtidigt reducerats till avstån- det b, som då svarar mot dosans infästning i en skiva av exempelvis 13 mm tjocklek, vars ena sida anligger mot rin- gens 13 övre parti. Ringens 13 höjd står således i sådan relation till avståndet a, att skivor av standardtjocklek kan användas.By turning the ring 13 to the position indicated by the line markings in Fig. 1, it is imparted to a lock against axial displacement relative to the box and the free portion of the mantle surface is thereby simultaneously reduced to the distance b, which then corresponds to the fastening of the box in a disc of, for example, 13 mm thickness, one side of which abuts the upper part of the ring 13. The height of the ring 13 is thus in such a relation to the distance a that discs of standard thickness can be used.

Ringen 13 uppvisar lämpligen två öron 16, som i ringens relativt dosan låsta arbetsläge blir orienterade tvärs stutsarnas 12 riktning, och genom att förse öronen 16 med genomgående borrningar 17 har man ytterligare under- lättat monteringen av dosan som nu enkelt kan fästas på plats.The ring 13 suitably has two ears 16, which in the locked position of the ring relative to the ring are oriented across the direction of the sockets 12, and by providing the ears 16 with through bores 17, the assembly of the box which can now be easily fixed in place has been further facilitated.

Ringen 13 medföljer följaktligen alltid dosan och tas bort vid behov. Dosan är dessutom på vanligt sätt försedd med andra apikanordningar eller -kanaler, icke visade på rit- ningen. Öronen 16 har lämpligen samma höjd som ringen 13.The ring 13 therefore always accompanies the box and is removed if necessary. In addition, the box is usually provided with other apical devices or channels, not shown in the drawing. The ears 16 suitably have the same height as the ring 13.

Claims

The invention may not be considered limited to the embodiment described and shown in the drawing, but may be modified within the scope of the appended claims. For example, the means 14, 15, which contribute to the ring 13 being prevented from displacing axially on the can surface of the box, may be of a different type than that shown and described. Apparatus or coupling box, specially arranged to be recessed into a wall, which box comprises a circular jacket (10), to which a bottom part (11) and a number of sockets (12) for receiving electrical wires adjoin , which sockets are oriented at a certain distance (a) from the front edge of the box, the free outer surface being arranged to releasably receive a ring (13) provided with nail instructions (16), by means of which the box is attachably adapted to either of two wall thicknesses, characterized in that the ring (13) and the mantle surface of the box have cooperating locking and guide means (14, 15) whereby the ring is axially displaceable but secured against rotation.

Box according to claim 1, characterized in that the ring (13) is equipped with inwardly curved grooves (14) for co-operation with guide pins (15).
