Title: Electroconductive plastics element for heater or electronic device - contains synergistic mixt. of carbon or graphite powder and fibres and opt. metal fibres
Inventor: TEGETHOFF CHRISTOPH
IPC: C08K3/08
Filed: 1990-07-31
Abstract: Electroconductive plastics element (I) is based on thermoplastic plastics (mixts.) (II) and contains electroconductive carbon and opt. metals dispersed homogeneously in the (II) matrix. Novelty is that it contains (a-1) electroconductive C black (IIIA) and/or graphite powder (IIIB) or (a-2) electroconductive C fibres (IVA) and/or graphite fibres (IVB) in a concn. at least large enough to equal or exceed the percolation limit of the conductive particles in (II), (b-1) 0-5 (wt.)% (IV) or (b-2) 0-4% (III) and (c) 0-5% metal fibres (VA) and/or metallised C fibres (VB) so that (b) is 0% only if (c) is over 0%. USE/ADVANTAGE - (I) is claimed for use as heating element or electronic device, esp. in vehicle and aircraft technology. It is useful e.g. for heating elements for flat structures such as mats, liq. containers, exterior mirrors for vehicles, windscreen or headlamp washer units, etc. (I) has better electrical conductivity than usual, which is obtd. with a relatively low electroconductive filler concn., since the (a)-(b)-(c) combination has a synergistic effect and also a stabilising effect which prevents the danger of self-destruction. This makes it possible to produce (I) easily by commercial methods, e.g. extrusion or injection moulding. The conductivity can be adjusted in a relatively wide range without impairing the processability or the mechanical properties of the prod. The resistance/temp. coefft. can also be adjusted within a wide range, including small values at (very) low temps., e.g. at -15 to -40 deg.C, esp. if (V) are used.

Filed: 1992-04-01
Abstract: The aim of the invention is to reduce the design complexity of low-voltage switchgear for the output or distribution of electric power, the switchgear having a guideway in the switchgear cabinet. This aim is achieved by virtue of the fact that the switchgear is fitted, parallel to the rack direction, with cross-struts having guideways for the racks, and also that the guideways are integral with the cross-struts or are integrally stamped from the same material. This aim is also achieved by virtue of the fact that the racks have a floor and, on both sides, below the plane of the floor, an outwards-facing guide edge disposed parallel to the floor plane and integrally joined to the floor. The invention is particularly suitable for low-voltage switchgear with, located in racks, switchgear assemblies such as circuit breakers, motor-protection circuits, other protection circuits, etc., at least the electrical connection between the bus bars and the switchgear being of the plug-in-type.
