Description
2888051 12888051 1
La présente invention concerne un dispositif de connexion rapide entre deux câbles électriques. The present invention relates to a device for fast connection between two electric cables.
Les installations électriques requièrent couramment l'alimentation de plusieurs consommateurs électriques depuis une même source. La source peut être triphasée et les consommateurs fonctionner en monophasé. Electrical installations commonly require the power supply of several electrical consumers from the same source. The source can be three-phase and consumers operate in single phase.
On utilise couramment un câble d'alimentation principal triphasé avec 5 conducteurs (3 phases, un neutre et une terre) ou 4 conducteurs sans neutre depuis lequel on raccorde des câbles dérivants monophasés avec 3 conducteurs (une phase, un neutre et une terre) ou des câbles biphasés avec 2 phases et une terre. A three-phase main power cable with 5 conductors (3 phases, one neutral and one earth) or 4 conductors without neutral is used, from which single-phase drift cables with 3 conductors (one phase, one neutral and one earth) are connected or two-phase cables with 2 phases and one earth.
Le câble dérivant qui ne doit supporter que le courant de chaque consommateur est en général d'une section inférieure à celle du câble d'alimentation qui doit supporter le courant cumulé de tous les consommateurs installés sur sa ligne. The drifting cable which only has to support the current of each consumer is generally of a section smaller than that of the power cable which must support the cumulative current of all the consumers installed on its line.
Une installation bien faite doit garantir l'équilibrage des phases et l'on doit s'assurer que l'on raccorde alternativement la phase de la dérivation monophasée sur les phases L1,L2 et L3 du câble d'alimentation. Proper installation must guarantee phase balancing and ensure that the phase of the single-phase bypass is alternately connected to the L1, L2 and L3 phases of the power cable.
Le raccord des câbles de dérivation sur le câble d'alimentation se fait usuellement par le truchement d'une boîte de connexion comportant un bornier à vis et plusieurs entrées de câble. The connection of the drop cables to the power cable is usually done through a junction box with a screw terminal block and several cable entries.
Le câble d'alimentation doit être coupé et chaque conducteur dénudé et introduit dans la boîte de connexion par un des orifices d'entrée de câble et chaque conducteur doit être raccordé sur un bornier de dérivation à vis. Le même câble d'alimentation doit subir la même opération pour sortir de la boîte. The power cable must be disconnected and each conductor stripped and inserted into the junction box through one of the cable entry holes and each conductor must be connected to a screw junction terminal block. The same power cable must undergo the same operation to exit the box.
Le câble de dérivation doit également subir la même opération pour obtenir une boîte permettant un raccordement électrique en T. L'installateur doit prendre garde sur site à raccorder en alternance, dans chaque boîte de connexion, la phase de la dérivation sur la bonne phase du câble triphasé d'alimentation pour garantir un bon équilibrage. The bypass cable must also undergo the same operation to obtain a box allowing electrical connection T. The installer must be careful on site to alternately connect, in each junction box, the phase of the derivation on the right phase of the three-phase power cable to ensure proper balancing.
Cette opération se fait usuellement sur le site d'installation et les boîtes sont fixées sur une paroi avant que les raccordements ne soient exécutés. This is usually done at the installation site and the boxes are attached to a wall before the connections are made.
2888051 2 Ce travail est souvent fait en hauteur avec un opérateur sur une échelle ou un quelconque moyen de levage dans des conditions de travail malaisées et éventuellement dangereuses. Ces mauvaises conditions peuvent conduire à des défauts de connexion potentiellement dangereux. 2888051 2 This work is often done in height with an operator on a ladder or any lifting device in difficult and possibly dangerous working conditions. These poor conditions can lead to potentially dangerous connection faults.
On connaît des dispositifs qui tentent d'améliorer les dérivations en utilisant du câble plat percé par des contacts en forme d'aiguilles, mais ils forcent à utiliser des câbles plats plus coûteux que des câbles ronds ordinaires et les contacts-aiguilles qui viennent se piquer dans le cuivre des conducteurs n'ont pas la capacité de passer du courant de puissance comme par exemple les 6 ampères que peuvent consommer certaines lampes de 1000 W. Le dispositif de connexion selon la présente invention permet d'effectuer des connexions de dérivation de puissance sans couper le câble principal d'alimentation, sans avoir à visser, avec un temps d'assemblage minimal et en garantissant un raccord électrique parfait qui puisse être contrôlé en atelier avant livraison. Devices are known which attempt to improve the leads by using flat cable pierced by needle-shaped contacts, but they force to use flat cables more expensive than ordinary round cables and needle contacts that come prick in the copper of the conductors do not have the capacity to pass the power current such as for example the 6 amps that can consume some lamps of 1000 W. The connection device according to the present invention allows to make power bypass connections without cutting the main power cable, without having to screw, with a minimum assembly time and ensuring a perfect electrical connection that can be controlled in the workshop before delivery.
Il permet aussi d'équilibrer les phases en choisissant dans chaque dispositif de connexion la phase du câble triphasé à laquelle sera raccordée la phase du câble de dérivation. It also makes it possible to balance the phases by choosing in each connection device the phase of the three-phase cable to which the phase of the branch cable will be connected.
Le dispositif de connexion selon l'invention présente un socle équipé de guidages axiaux, un jeu de contacts double face avantageusement rassemblés sur un support et un couvercle de dérivation avec sortie de câble. The connection device according to the invention has a base equipped with axial guides, a set of double-sided contacts advantageously assembled on a support and a bypass cover with cable outlet.
Le socle est destiné à recevoir le câble principal dont on aura préalablement retiré sur une courte longueur la gaine extérieure et écarté chaque conducteur qui sera aligné dans chacun des guidages. Les conducteurs isolés se trouvent ainsi alignés dans le même plan de socle, mais sans avoir été coupés. The base is intended to receive the main cable, the outer sheath of which will have been removed for a short distance and spaced apart each conductor which will be aligned in each of the guides. The insulated conductors are thus aligned in the same base plane, but without having been cut.
La plaque intermédiaire porte-contacts est équipée du nombre de contacts nécessaire, par exemple 5 contacts correspondants à trois phases, un neutre et une terre. The contact carrier intermediate plate is equipped with the necessary number of contacts, for example 5 corresponding contacts in three phases, a neutral and a ground.
Ces contacts sont disposés de façon à correspondre aux guidages du socle. Ils sont de type auto-dénudant à double face composés par exemple de deux pinces adossées. Lors de la fermeture du dispositif, ils sont destinés à mettre au même potentiel les 2888051 3 conducteurs du câble d'alimentation avec ceux du câble dérivant par une simple opération de pression élastique. These contacts are arranged to correspond to the guides of the base. They are double-sided self-stripping type composed for example of two clamps backed. When closing the device, they are intended to put the same potential 2888051 3 conductors of the power cable with those of the drifting cable by a simple operation of elastic pressure.
Les contacts ont une forme à peu prés symétrique comme un tube évidé et découpé comme une lyre de préférence double. La lyre étant double et pinçant le câble sur ses faces intérieures, elle permet ainsi de faire plusieurs points de contact par pincement sur le conducteur dénudé. The contacts have a shape almost symmetrical like a tube hollowed out and cut like a lyre preferably double. The lyre being double and pinching the cable on its inner faces, it allows to make several points of contact by pinching on the stripped conductor.
Les bords extérieurs de ce tube sont suffisamment coupants pour traverser l'isolant du câble pressé dans le contact et le contact est suffisamment élastique pour pincer le conducteur enfoncé dans la lyre. The outer edges of this tube are sufficiently sharp to cross the insulation of the cable pressed in the contact and the contact is sufficiently elastic to pinch the driver driven into the lyre.
La fente de pincement peut être d'une épaisseur différente de chaque côté pour raccorder deux câbles de sections différentes. The nip slot can be of different thickness on each side to connect two cables of different sections.
Dans une forme particulière de l'invention, les faces de contact intérieures des pinces présentent des découpes perpendiculaires a leur axe permettant d'immobiliser axialement le câble connecté. In a particular form of the invention, the inner contact faces of the clamps have cutouts perpendicular to their axis for axially immobilizing the connected cable.
Le couvercle dérivant reçoit le câble dérivant et est équipé de rainures. Le choix de la rainure dans laquelle on dispose la phase du cable dérivant détermine la phase du câble d'alimentation à laquelle elle sera raccordée. The drifting lid receives the drifting cable and is equipped with grooves. The choice of groove in which the phase of the drifting cable is available determines the phase of the power cable to which it will be connected.
