Definitions

  • the present invention concerns an electric branch joint between a primary conductor and one or more secondary conductors, it being understood here and in the following that by electric conductor it is meant: a wire composed of an electric conducting material inner 5- core and an outer insulating sheath.
  • Present invention's scope is thus to obtain an electric branch joint with no primary wire interruption, not requiring any weld, being already protected by insulating materials, easy to install and 5. inexpensive.
  • a joint which includes an external shell made up of two half-shells, capable of housing a connecting terminal made up of a single piece of conducting material and so designed that it can receive and firmly hold by means of a grub screw a 10. conductor whose insulating sheath had been removed from a certain area, said connecting terminal being provided with four possible exit connections, set at right angles with each other.
  • the two half-shells be identical. They can be equipped with guides and two sliding blocks to obtain a simple shell 15. snap closure.
  • the two half-shells can also be symmetrical, so that they can be turned around, for shifting the exit connections.
  • Said connecting terminal can be shaped as a parallelepiped and in particular have a square cross-section so that it can be rotated
  • This terminal is provided at each end with two deep slots, at right angles with each other, internally threaded.
  • a grub screw with socket head, externally threaded In each slot there is therefore a housing for a conductor, that can be deeply screwed into the slot. In each slot there is therefore a housing for a conductor, that can be
  • one of the slots has its walls pierced by two holes: in this slot it is thus possible to pass through an additional conductor, at right angles with the conductor housing mentioned above.
  • the connecting terminal operates in this manner, e.g. : the primary conductor, having its insulating sheath removed from the interested zone, is housed in the above mentioned slot, transmitting current by direct contact of its conducting core with the connecting terminal slot throat.
  • the secondary conductor having its insulating sheath
  • the above detailed connecting terminal is held inside an insulating shell, composed of two half-shells, to protect and insulate it.
  • the two half-shells forming the protective shell are preferably not only identical, but symmetrical about a transversal plane, so that they can be joined to form the shell in two different ways, allowing for various assembly combinations.
  • Said half-shells are equipped with guides, on which two sliding 5. blocks can snap the shell.
  • Fig. 1 shows a perspective exploded view of the proposed connecting terminal; 10.
  • Fig. 2 and 3 show respectively an external and an internal view of one half-shell;
  • Fig. 4 shows a sectional view of the two half-shells coupled, one of them being sectioned through line 4-4 as shown in Fig. 2;
  • Fig. 5 shows a left side view of the half-shell shown in Fig. 2; 15.
  • Fig. 6 and 7 show respectively a view through section-lines 6-6 and 7-7 as shown in Fig. 2;

  • Each half-shell G is formed by a body 30, lying all at one side of 5. plane Y-Y, this one being-- the .contact plane between the two half-shells.
  • the body 30 has_an internal cavity -29 where connecting terminal M is housed, and lateral edges; two of them, on opposite sides, are equipped with two guides 20, interrupted at their mid-point by a projection 21.
  • Body 30 is provided with a hole 22,
  • U-section shaped slide block 40 ( Figures 8-10) has projections 41 interrupted by a recess 42, thus enabling it to receive projection 21. As shown in Fig. 9, the sliding block is shaped to accept the 20. facing edges of body 30, equipped with guides 20.
  • Connecting terminal M is located in cavity 29 of the half-shell and held within the shell by the other half-shell, set on the first half-shell in accordance with the type of branching required.

Abstract

Raccord de dérivation électrique permettant la connexion électrique de deux conducteurs, sans interruption du câble principal. Ledit raccord se compose d'un matériau conducteur de borne, qui véhicule un courant électrique dans toutes les directions, de deux demi-boîtiers isolants équipés de guides, et de deux blocs coulissants permettant une fermeture simple à enclenchement des deux demi-boîtiers, par glissement desdits blocs sur lesdits guides.
