Abstract

The resistance has a cartridge heater housed in a brass body and receiving current through terminals sealed in thermal cement. The terminals connect the heater across ceramics. A connector technology includes springs (6) receiving lugs (7) set on a wires (8). The wires including a power cable are set on the cable, and protective springs (11) are housed on the lugs. The springs, protective springs and wires are separated by glass fiber sheaths (12), teflon sheaths (13) and silica sheaths (14). A thermo-retractable sheath (15) imprisons the silica sheath.

Description

1 La présente invention concerne une résistance et sa connectique pourThe present invention relates to a resistor and its connectors for

sublimer le polystyrène servant d'isolation dans les cloisons du bâtiment afin de réaliser des galeries pour le passage des gaines électriques ou hydrauliques. Les résistances ainsi que leur connectique que l'on trouve traditionnellement dans le commerce, sont affectées de durée de vie très limitée, suite aux contraintes thermiques, mécaniques et chimiques qu'elles subissent. La résistance ainsi que sa connectique permettent de remédier à cet inconvénient. La résistance comporte en effet, selon une première caractéristique une cartouche chauffante logée dans un corps en laiton, chapeautée par une céramique. L'alimentation électrique de cette résistance se fait par l'intermédiaire de deux bornes en inox, solidaires de celle-ci. Du fait des tractions et torsions diverses, la connectique est composée de ressorts capables de résoudre ces contraintes mécaniques, tout en transmettant le courant. Diverses gaines ont été soigneusement choisies de manière à lutter contre les polluants chimiques que contiennent les polystyrènes composés d'additifs ; elles isolent les ressorts constituant la connectique de la chaleur ainsi que du courant électrique, très basse tension. La manipulation de cette résistance se fait par l'intermédiaire de sa prise en main, élément important de protection contre les brûlures pouvant être infligées à l'utilisateur. Les dessins annexés illustrent l'invention : La figure 1 représente la résistance non assemblée.  sublimate the polystyrene insulation used in the walls of the building to make galleries for the passage of electrical or hydraulic ducts. Resistors and their connectivity that is traditionally found in commerce, are affected by very limited life, due to thermal, mechanical and chemical stresses they suffer. The resistance as well as its connections make it possible to remedy this disadvantage. The resistance comprises, in fact, according to a first characteristic a heating cartridge housed in a brass body, capered by a ceramic. The power supply of this resistance is made by means of two stainless steel terminals, integral with it. Because of the various pulls and twists, the connector is composed of springs capable of solving these mechanical stresses, while transmitting the current. Various sheaths have been carefully selected to control the chemical pollutants contained in polystyrene compounds; they isolate the springs constituting the connection of the heat as well as the electric current, very low voltage. The manipulation of this resistance is done through its grip, important element of protection against burns that can be inflicted on the user. The accompanying drawings illustrate the invention: Figure 1 shows the unassembled resistor.

La figure 2 représente, en coupe, la résistance assemblée. La figure 3 représente la connectique de cette résistance, non assemblée, La figure 4 représente la résistance et sa connectique assemblée, Tous les plans sont à l'échelle 1. En référence à ces dessins, la résistance comporte une cartouche chauffante (1) logée dans un corps en laiton (2). Les bornes (3) assurent la liaison électrique de la cartouche chauffante (1) à travers la céramique (4). Le ciment thermique (5) solidarise cet ensemble. La connectique se compose des ressorts (6) dont le diamètre interne permet de se loger sur les bornes (3) légèrement en force. Ces mêmes ressorts (6) reçoivent les cosses (7) préalablement serties sur les fils (8) composant du câble d'alimentation (9). Afin que les tractions exercées sur la connectique ne puissent faire glisser les fils (8) dans leur câble d'alimentation (9), une bague (10) doit être sertie. Les ressorts protecteurs (11) protègent les fils (8) des torsions et chocs divers. L'isolation électrique est assurée par l'intermédiaire de la gaine 2905820 2 fibre de verre (12) à la limite de 4 centimètres de la résistance pour éviter qu'elle ne se consume. Cette isolation électrique est renforcée par la gaine téflon (13) qui assure aussi un rôle mécanique du fait de sa non porosité. L'isolation thermique est assurée par la gaine en silice (14) repliée sur elle-même pour éviter l'effilochage. Elle recouvre toute la connectique jusqu'à la céramique (4) 5 de la résistance. L'ensemble de ces trois gaines est prisonnier de la gaine thermo-rétractable (15) après l'avoir rétreinte. Une prise en main (16) en silicone recouvre cette gaine thermo-rétractable ( 15). La résistance selon l'invention est particulièrement destinée à sublimer le polystyrène servant d'isolation dans les cloisons du bâtiment, afin de réaliser des galeries pour le passage 10 des gaines électriques ou hydrauliques.  Figure 2 shows, in section, the assembled resistance. FIG. 3 shows the connection of this resistance, unassembled, FIG. 4 represents the resistance and its assembled connection, All the planes are at scale 1. With reference to these drawings, the resistor comprises a heated cartridge (1) housed in a brass body (2). The terminals (3) provide the electrical connection of the heating cartridge (1) through the ceramic (4). The thermal cement (5) secures this assembly. The connector is composed of springs (6) whose internal diameter allows to lodge on the terminals (3) slightly in strength. These same springs (6) receive the lugs (7) previously crimped on the son (8) component of the power cable (9). So that the pulls exerted on the connector can not slide the son (8) in their power cable (9), a ring (10) must be crimped. The protective springs (11) protect the wires (8) from various twists and impacts. Electrical insulation is provided through the sheath 2905820 2 fiberglass (12) at the limit of 4 centimeters of resistance to prevent it from being consumed. This electrical insulation is reinforced by the Teflon sheath (13) which also has a mechanical role due to its non-porosity. Thermal insulation is provided by the silica sheath (14) folded on itself to avoid fraying. It covers all the connectors to the ceramic (4) 5 of the resistance. All of these three sheaths are trapped in the heat-shrinkable sheath (15) after having shrunk it. A grip (16) silicone covers this heat-shrinkable sheath (15). The resistance according to the invention is particularly intended to sublimate the polystyrene serving as insulation in the building partitions, in order to make galleries for the passage of electrical or hydraulic ducts.
