Smoke cus te rme! Dung Description; Electrical busbar trunking system with changeable cable outlets

The invention relates to an electrical busbar trunking system with variable line outlets. Such busbar trunking systems consist of prefabricated busbar boxes that are assembled on site at the consumer's premises to form a distribution system, the length of which can be up to 100 m and more. The rail boxes are long housings made of sheet metal or plastic with built-in, preferably bare busbars, which are provided at individual points with line connection devices for the cable outlets * The assembly of the boxes and the electrical connection of the rails is usually done by screwing.

The object of the invention is to simplify the assembly of the trunking units is thus to reduce to ^1, the assembly times and costs to the consumer * invention, this is achieved in accordance with _(that a connecting element is provided between each two concatenated, crates, the both contact elements for a detachable electrical connection ^ the busbars as well as is equipped with means for a detachable mechanical connection of the boxes. As contact elements such for a detachable screwless electrical connection of the busbars can be provided, e.g. _e according to the type of contact sockets or Kontakttu.'pen for round rails or, according to the type of Lyra contacts or the like, for flat bars, are preferably those known constructions which, due to their design, cause an increase in contact pressure at the coupling point in the event of a short circuit n take place, with resilient latching lugs on the connecting element snap into corresponding recesses in the boxes to be assembled in a self-locking manner.

In Figs. 1 and 2, an embodiment of the invention is shown. The rail box consists of a long housing 1 which is closed by a cover 2. In its interior, rigid unisoUerte conductors 3 are arranged and fixed in position by support members. 4 At individual predetermined positions of the track box terminal devices L · are attached via which the

Branch lines 6 to the consumer are connected to the busbars 3 will·

According to the invention, a connecting element 7 is provided at the joints between two adjacent trunking units, which on the one hand with contact elements 8 for a releasable electrical connection of the busbars 3 and on the other hand with means 9 for a releasable mechanical connection Connection of the two boxes is provided with the connecting element 7,

Lie contact elements 8 (Fig, 2) are designed in the embodiment for a releasable screwless electrical connection and consist of contact sleeves for round rails, which can be slotted at both ends 8a and self-resilient or externally sprung 8b. They have a collar 8c on one side and are held captive in the connecting element 7 in the bores of its insulating body by flanging 8d. The busbars 3 of the busbar boxes to be connected are inserted into the sockets 8. The two long housings 1 are mechanically connected at the same time by a form fit. In the exemplary embodiment, an elastic form fit is shown by simply snapping into one another, in which a suitable number of resilient locking lugs 9 of the connecting element automatically lock into corresponding recesses Io of the long housing 1 when the boxes are pushed on.

Of course, other known means for the mechanical It is possible to connect the long housings. For example, it can be advantageous to lock the mechanical connection to a separate element, for example a resilient clip to be assigned. Then enough for that Joining the housing together is already a simple form fit, the last degree of freedom of which is blocked by the clamp. Can do the same the electrical connection can also be made by screw connections, the clamping screws of which through suitable closable openings in the trunking box and are similar in the connecting element. The connecting element 7 can can also be designed in variants as L, T or cross pieces and are used as a component for changing direction and branching the rail lines *
