Definitions

  • This invention refers to a terminal box, of those used in various installations, to route and bypass cables provided with a core and insulation sheathing.
  • a typical case is the box used in the bypass of a multiple cable bundle, which consists of a box with an access cover. Splicing and bypassing is carried out inside the box, either manually or using more or less sophisticated splicing devices.
  • the cables to be bypassed must be cut in order to splice them to the same line or to the corresponding bypasses, using terminal strips with bolted mechanical splices or similar.
  • connection box of this invention has special technical features that enable electrical cables to be bypassed in a quick, simple and safe manner, without using coupling screws or clamps on the cable or cables to be connected and without the need to strip the cables to be connected.
  • connection box of the invention consists of a base or box containing one or more sockets with slots to house separate electrical connectors.
  • Each connector consists of an electrically conductive metal plate with at least one notch with cutting edges to tightly insert the cable or cables sideways.
  • This notch has a smaller width than the external diameter of the cable and equal or slightly smaller than the diameter of the conductive core, so that when the cable is inserted in the aforementioned notch, the sheathing of the cables to be connected is cut and the core becomes in close contact.
  • the connector is made of electrically conductive material, the conductive cores of all cables inserted in the same connector are directly interconnected.
  • the cover of the box has projecting parts, which press the connected cables sideways, preventing them from coming out of the corresponding notches.
  • the connectors are flat and the notches of each connector are at two levels, in order to place the main cables in one of them and the bypass cables in the other. This means that the insertion position of the main cables and of the bypass cables can be distinguished reducing the risk of error in insertion.
  • the connectors can optionally consist of flat parts, folded in a "U”, with the connection notches aligned and shaped in the respective sides of the "U” configuration.
  • connection box may have connectors with notches of different widths so that cables with different diameters can be electrically connected in the same box.
  • the cover and the base may be joined using complementary press-on elements, threaded tightening elements or any other conventional fastening element, as this does not affect the essence of the invention.
  • the box consists of a lower base (1) and a cover (2), which in the assembly position form openings (11), which are longitudinally facing each other for the inlet and outlet of conductor cables (3), and side openings (12) for the outlet of bypass conductor cables (3).
  • a socket (13) with slots (14) to insert the electrical connectors (4) is at the bottom of the box (1).
  • each electrical connector (4) consists of a flat, electrically conductive metal part, with two notches (41) with cutting edges to insert the cables (3) to be connected.
  • the notches in the connector are placed at two different heights, with the upper notch (41) aligned with a castellated shape projecting part to route the main cable (3), and the lower notch (41) aligned with a housing to place the bypass cable (3).
  • the width of the notches (41) is smaller than the outer diameter of the cables (3) to be connected, so that when the cables (3) are inserted inside, the cutting edges cut the sheathing of the cables (3), make contact with the core, and therefore the connector (4) ensures the electrical interconnection of the main and bypass cables (3), inserted in the notches (41).
  • connectors enable a cable (3) to be bypassed without the need to cut its core nor to strip or remove part of the sheathing, as the sheathing is cut by the cutting edges of the connector when the cable is inserted sideways in the notch of the connector.
  • the notch (41) is sufficiently deep to house at least one cable (3), although it has also been planned that two or more cables (3) can be inserted in the same notch (41) of the connector (4), so that they are electrically connected by contact of the corresponding cores with the connector (4).
  • the connectors (4) consist of flat parts, folded in a "U”, with cutting-edged notches (41) on the sides, so that the cables (3) to be connected can be inserted sideways.
