Definitions

  • This invention relates to a non PVC permanent connector suitable for, although not limited to, connecting flexible electrical cables, cords, flexes and the like to each other for extending or joining the same for
  • an electrical flex or cord is a flexible insulated cable often used for carrying electrical current from an electrical power source to an electrical apparatus.
  • a cable comprises of two, three or four electrical conductors that are each encased in a protective and non-conducting sheath of plastic, or the like, insulating material.
  • the insulating sheath material is partially removed so as to expose the conductors, after which the conductors of one cable are connected to corresponding conductors of the other cable. It will be appreciated that respective conductor connec tions should again be insulated to prevent, for example, electrical short circuit.
  • Different cable connectors for connecting and lengthening electrical cables or cords are available on the market. These include, for example, male and female connectors, wherein the male connector is crimp-fitted to one cable and the female connector crimp-fitted to another cable. These types of connectors also may be in the form of spigot and socket type arrangements.
  • Another known cable connector provides a substantially tubular body having two opposite open ends that are dimensioned for receiving end portions of two conductors to be connected. Once the end portions of the respective conductors have been positioned in the tubular body, the latter is crimp-fitted to the conductors so as to grip the respective end portions of the two conductors in electrical contact.
  • the conductors are maintained in the tubular body by means of screws extending through a wall of the tubular body and engaging the respective conductors.

  • known cable connectors generally all suffer from one or more disadvantages. Some of the prior art connectors are relatively complicated in their design and hence are relatively expensive. Other connectors provide relatively little efficiency in keeping the conductors in electrical contact, or are relatively dangerous to use and difficult to apply as special tools are required to enable the connection. Yet a further disadvantage of some known cable connectors is that they are sometimes unsafe to use, especially in domestic environments. Object of the invention

Abstract

Extend O Cord est un connecteur permanent non PVC destiné (la liste n'étant pas exhaustive) à connecter des fils électriques souples, des cordons, des circuits imprimés souples et d'autres éléments similaires entre eux de façon à rallonger ou connecter ces éléments dans le cadre de l'utilisation d'appareils électriques (1, 7). Des inserts en laiton galvanisé avec des protecteurs de fil permettent à l'utilisateur de connecter, modifier ou rallonger n'importe quel cordon électrique à deux ou trois conducteurs allant jusqu'à 16 AMP, 250V ou deux à quatre conducteurs allant jusqu'à 32 AMP, 380V, assurant un flux de courant continu (2, 4). Extend O Cord est facile à assembler et il est prêt en quelques minutes. Le produit fini est antichoc, étanche, ignifuge et, même si on l'étire(1, 3, 6), il reste intact. Le canal isolant central en forme de U et la charge polyuréthane Fastcast offre une tranquillité d'esprit par l'élimination des courts circuits électriques (6, 8).
