Clip for fasterning cables on roof overhangs

Abstract

A clip engaging under the wall-side edge trim of panels for cladding roof overhangs solves the problem of laying connection cables for solar installations and monitoring said cables.

Description

[0001] Cable fastening clip for roof overhangs Z USAMMENFASSUNG A clamp, snapped under the wall-side end profile of panels for cladding roof overhangs, solves the problem of laying connection cables for solar systems and monitoring them.

[0002] Cable fastening clip for roof overhangs H INTERGRUND DER E RFINDUNGSolar panels and balcony power plants require the installation of larger-diameter connection cables, often along the front of the house. The simplest solution is often to remove the cladding from the underside of the roof overhang to run the cables underneath. However, this is also quite labor-intensive, so the cables are often simply nailed to the panels or the facade with clips. This is not only unsightly but often doesn't hold up in the long run. Furthermore, to optimize solar systems, it's necessary to monitor the interaction of different modules and their aging throughout the year and under varying sunlight. This should be possible regularly and as easily as possible. UFGABENSTELLUNGIt is therefore an object of the present invention to develop a simple and durable method for laying such cables, but also, for example, antenna cables, whereby these should remain accessible as much as possible and a possibility of monitoring individual strands over the course of the year should be provided. PREVIOUS ART DE 202009007419 U1 describes a closed cable duct for receiving and holding lines or cables that connect solar modules or photovoltaic modules to terminals.

Claims

US 10253504 A describes the installation of heating cables in channels that also run along the edge of a roof overhang. US 11862956 B2 describes a clamp with pockets arranged one behind the other, into which a cable can be clamped on one side and an object (e.g., a tile or a segment of a roof edge) on the other. OBJECTIVE OF THE INVENTION The objective of the present invention is therefore to create a fastening system that is visually unobtrusive, quick to install, and durable. Furthermore, the system should be as easy to monitor as possible. SOLUTION The inventive step is to utilize the favorable installation position at the roof overhang and to attach the cables to the end profile usually present there using a secure yet easy-to-use clamping device, and furthermore to make their current output readable by means of a simple LED display for each strand.One advantage that facilitates the design is that all European manufacturers of plastic panels for the underside of roof overhangs offer a similar profile for the wall-side edge, and these almost always feature a raised edge for rainwater drainage. Therefore, a system of clips was developed that encompasses this raised edge and offers recesses of 2 mm, 4 mm, and 6 mm to accommodate common cable diameters. The monitoring problem is solved by measuring the output of a coil through which the current of a strand is passed, embedded in the retaining clip. For clarity, the reading is displayed by one or more LEDs located directly next to or around the retaining clip. DESIGN AS SHOWN IN THE DRAWING Fig. 1 shows an example of the end profiles commonly used in Europe for a cover (1) on the underside of roof overhangs, with attached clamps (2-4) through which the cables (5, 6) are routed. A measuring coil (7) is integrated into the cable holder, and the reading is displayed by a chain of small LEDs (8) around the measuring point.
