Adapter for power distribution bars

The invention relates to an electrical connection device direction for power distribution bars with continuous' connection, whose conductors in an open channel within are arranged on the rail "

Such for example from the "British patent 1000 ^ 30 "Known systems require the use of special connection devices for the beam guidance between the system and the devices to be supplied. These connection devices are called adapters «

The object of the invention is to create an adapter of this type, with one with a view to puncture accuracy

and adaptability improved construction.

In one embodiment, the adapter according to the invention

WCXDb uictioi 'cxu XOUXXCJ-CJaUCo vrcuau.Dc avuj uu.u gxusu j.ui

essential tubular jacket and a detachable base closing it on one side, movable contact members, a terminal block and a mechanical fastening device, which are all mounted on the base, so that they are accessible by removing the jacket from the base. This design facilitates access 2m to the internal parts for the purpose of pipe connection and maintenance.

Preferably eixtiiäll; döj? Adapter femei ⁵ a carrier that carries a ground contact and / or a switch that has a fuse. This support element engages releasably in the base and is easily removable when the jacket is removed from the base.

This embodiment is particularly advantageous in terms of it on the rationalization of manufacturing, as it enables a number of adapters to be assembled for different purposes Manufacture individual parts or modify an adapter by exchanging one carrier element for another.

Further advantages and details of the invention will emerge from the following description, in which, with reference

on the drawing exemplary embodiments of the invention in more detail are explained.

In the drawing shows Fig. 1 is an exploded view of an adapter

Fig. 2 is a perspective view of two different support elements

Fig. 3 is a perspective view of two further support elements.

The adapter shown in the drawings is for use only with a S tromvert eilerechi ene determined according to the "British patent 1000093O" and corresponds in some construction elements and punctures of the connection device, which the Forms the subject of British patent 1000925.

The adapter has a two-part housing, which consists of a substantially tubular jacket 1 and a flat sookel 2, which is used to sleep in the lower ? ^ de of the jacket can be snapped into place. Both parts 1 and 2 are preferably as molded parts made of electrically insulating Resin plastic material made. A rotatable connector unit 3 is arranged at one end of the base 2, which has a tubular body 4 which at its lower end has a flange 5 with a protruding one Pinger 6, which in the assembled adapter through a

He has one central SnM-H? κ sur inclusion of the signs »8 · ±» · β T-rena ·! * - mentes 9, the upper nose of which protrudes above the insert 7 · An Elemmhülsen 10 fits on the rabbit of the separating element 9 · The Klemmhtilse 10 has a pair of diametrically arranged, radially displaceable locks 11 and a central rectangular recess, which the nose of the separating element 9 and the vertical legs vcn two electrical Contact a 12 picks up, each of which is a radial Contact finger 13 has. The components described above the dreüberen steekereinhelt 3 are on this 7sise dor ** h.

Except for the Contacts 12 are all parts of the connector device, sweekmäfligerweise plastic molded parts.

Electrical connection to the contacts 12 is through. Conductor 14 produced, which end in 15 Steckhfilsen and the other ends of which are fastened in a Klemenbloek 16 -are that connect to siaem cables not shown

The terminal block 16 is fastened to the base 2 by means of a nut 17 ″ which is screwed onto a threaded nipple (not shown) passing through the base 2. The terminal block 16 and the nut 17 also serve to provide a mechanical Fastening device in the form of a substantially U-shaped element made of spring steel (or other suitable resilient material) to fasten, with a flat base plate 18 and opposing legs 19 »20, the free upper ends of which are resiliently movable towards and away from one another« one side the base plate 18 is elongated and shaped in such a way that it can snap into an annular groove on the circumference of the flange 5 of the tubular body 4. The base plate thereby simultaneously serves to axially fix the tubular body A _1, that is to say it holds it down on the base 2 and in a simplified manner this way further the manufacture and the assembly and disassembly ·

The upper ends of the legs 19 and 20 are to the outside Shaped concave brackets for insertion between opposing flanges of the power distribution bar, a Leg 20 has a recess in which a sleeve 21 with

"is attached to accommodate an operating sea hood 22. The inner end of the screw 22 comes to the opposite leg 19 to the plant, so that through Rotation of the screw through the sleeve and against the leg 19, the "two ochenkel 19 and 20 pressed apart and clamped between the flanges of the power distribution rail will. A push button 23 with an enlarged head 25 protrudes through an opening 24 in the jacket 1 the jacket 1 and the leg 19 is included. This push button 23 can be used in combination with the screw 22 be to the legs 19, 20 to facilitate the Remove from a power distribution rail to push towards each other. The preload and the spring action of the TJ element It is sufficient that the adapter is carried by the power distribution rail before it is tightened by tightening the screw 22 is attached.

The adapter is completed by a molded support member 26 which is shaped to be attached to one end of the Base 2 fits tightly into the jacket 1. The base 2 has a laterally undercut groove 27 with a dovetail cross section for receiving a corresponding projection 28 on the bottom of the carrier element 26. In this way the carrier element can be pushed into the correct position on the base 2 with the jacket I removed. By The carrier element is snapped into place

The carrier element shown in Pig «1 bears an errederbelasted earth conference 29, who was on an earth conductor? in the power distribution rail attacks »However tc« rm in the Carrier element too, -as in Tig. 2 is shown a fuse 30 (Pig. 2 A) or a switch arrangement 31 (Pig. 2 B), each of which has its own special line 3OL or 31L for connection to a contact 13. Figure 3 shows two further modifications in which the Earth line is omitted.

In this way it is clear that any one of the five illustrated Ausftihrungsfonaen the Träperelement during of assembling the adapter can be selected from standardized parts or within the useful life of the Adapter can be replaced by another.

The construction described above, in which oils are different electrical items are mounted on the Obex'fläche of the base 2, facilitates the assembly of the adapter and the laying or re-laying of the lines, for which purpose the jacket 1 is completely removable to the individual parts easily accessible.
