Definitions

  • This invention relates to an energy carrying cord location of joining insulator for insulating an energy-carrying cord joint during the joint forming process that involves the joining of a number of individual energy carrying wires, against both an exposure to the environment and a transfer of energy between separate lines of energy carrying wires. While not so limited the invention finds useful application for isolating electrical cord joints.

  • an energy carrying cord location of joining insulator according to the invention in the form of an electrical cord location of joining insulator is generally indicated by reference numeral 10.
  • the insulator 10 comprises a linearly extending insulating housing 12 that is constituted from at least two sealably inter-engageable housing parts 14 (as shown in their engaged conditions in figures 2, 3, and 8) that, once engaged, define a generally tubular wire connecting zone 16, locations of sealable cord access to the housing 12 extending along apertures 18 formed at opposite ends of the housing 12, at least once constituted from its parts 14, and a linearly extending wire isolating facility generally indicated by reference numeral 20 and discussed below in detail for each of the embodiments, along which a number of inter-isolated wire

  • the wire-connecting zone 16 is consequently formed once the bodies 24 are secured to one another.
  • the wire isolating facility 20 is in the form of a wall defining formation as provided by a tri-wall facility 30 of which the various walls 32 radiate at fixed inter wall spacings from a common central axis 34, as more clearly shown in figure 4. While the facility 30 fully removably fits the housing 12 its diameter is selected to snugly fit the inner end regions 36 of the opposite bodies 24. The length of the facility 30 is in fact selected so that its one half fits the inner end region 36 of the one body 24 and its other half the inner end region 36 of the other body 24 resulting in a firm and snug overall fit of the facility within the zone 16 once the bodies 24 are fully engaged.

  • the cross sectional areas of the bodies 24 narrow in the direction of their aperture presenting ends, at least from beyond the reach of the facility 30, forming tapering end regions 38.
  • the insulator 10 incorporates cord end region sealing in the form of a ring seal 42 that is locatable onto the end lengths 44 of each of opposite cords 40.
  • the degree of body narrowing or tapering is naturally coordinated with the diameter of the seals 42 as in turn adequately snugly fitting the relevant cord end lengths 44 to cause the bodies 24 to progressively pinch the seals 42 onto the cord end lengths 44 in sealing the cords 40 in their apertures 18 on the progressive engagement of the bodies 24. It will be appreciated that variation in seal diameter can accommodate a variety of cord diameters while the insulator 10 can also be made in a variety of sizes.

  • the arms 48 are receivable down guides 52 presented by the other section 46 that are formed with bottom end catch formation snap fit apertures 54.
  • the snap fit configuration will naturally be configured to obtain a sealing fit between the sections 46 once the catch formations 50 are received in the apertures 54.

  • the subsequent step involves the operative positioning of the facility 30 within the connecting zone 16 and amongst the joined wiring 62 in a way that results in each of the lengths of joined wiring extending along a wire accommodating path 22 thus being sealed against short circuiting from one another by the walls 32 of the facility 30.

During such engagement the opposite halves of the facility 30 become received within the inner end regions 36 of the bodies 24 until becoming firmly lodged within the connecting zone 16.

  • a cord joining action commences by the location of cord end lengths of cords 40 along the end recesses 61 formed along the section 46 that houses the core 58 and that on combination with the matching recesses 63 of the other section 46 on their engagement form the apertures 18.
  • Matching wiring ends are subsequently secured into forming lengths of joined wiring 62, again typically by a soldering process.
  • the lengths of joined wiring 62 are each located along a channel 56 causing their separation against short-circuiting by way of the separating wall 60.

Abstract

Isolateur (10) de jonction et d'étanchéité pour un cordon électrique, comprenant un boîtier isolant (12) constitué de deux corps (24) en forme de coque pouvant être emboîtés l'un dans l'autre de manière étanche qui, une fois emboîtés, définissent une zone de connexion de fil (16), des ouvertures (18) d'accès du cordon à la zone (16) et un élément linéaire d'isolation de fil sous la forme d'un élément à trois parois (30) qui peut être situé le long de la zone (16) et sépare des longueurs de fil (62) connectées pour les protéger contre les courts-circuits. L'étanchéification du cordon le long des ouvertures (18) est réalisée par des joints (42) qui se retrouvent pincés sur les extrémités du cordon lors de l'emboîtement des corps (24).
