Abstract

Device for connecting multiple taps on an electrical supply line with twisted insulated electrical conductors. It includes sockets 7, 8 or tap-off blocks connected by short insulated conductors 9, 10, 11 to insulation piercing connectors attached to each of the insulated conductors of the power line, the socket current or the tap-off unit being held on the power supply line using at least one clamp 4.

Description

Device for connecting multiple leads on a line

  electric conductor with twisted insulated conductors.

  The present invention relates to a connecting device

  multiple branches on a power line with

  twisted insulated conductors, such as a line with two phase conductors and a ground conductor or three phase conductors, and

a ground conductor.

  For both final installations and site installations, a box with a number of branches equal to the number of

  derived lines to supply power.

  These diversions are generally of great length and come to constitute obstacles in a large area in the vicinity

  In addition, if the number of derived lines required

  re goes beyond the possibilities of connection to the cabinet, it is necessary to replace the cabinet by another more important or

to add another.

  The object of the present invention is to provide an arrangement

  plug-in system that avoids the presence in a large area of long drop cables and allows connection

  the needs of the additional derived lines on the supply line.

according to need.

  The connecting device according to the invention is

  characterized in that it includes sockets or branch blocks connected by insulated conductors of short length

  insulation-piercing connectors attached to each of the con-

  insulated conductors of the power line, outlets or bypass blocks being maintained on the line

  feeding with at least one stirrup.

  Preferably, the sockets or blocks of debris

  are placed on the feed line at equidistant intervals. Figure 1 shows in plan a socket

  phase conductors and a ground conductor.

  In FIGS. 1 to 3, the supply line 100 comprises the phase conductors 1 and 2 and the earth conductor

  short-lived conductors 9, 10, 11 respectively to connections

  insulators 16, 17, and 18, fixed to the conductors

  phase 1, 2 and the earth conductor 3.

  These connectors will be waterproof for use in damp locations. Caps 14, 15 protect the dual socket

dust and moisture.

  The branch block of FIGS. 4 and 5 is also arranged on a phase-conductor feed line 21,

22 and earth conductor 23.

  It is fixed on the line by the stirrups 24 The conductors are held inside the body 24 A in the semicircular channel by the cap 26 The branches 27, 28 are connected by short conductors 29, 30, 31 to insulation piercing connectors not shown in these figures, but

similar to those of Figure 3.

  The device of the invention is particularly useful

  not only for permanent electrical installations, but also for construction sites where electrical power connections -3- are multiple and often scattered over the entire surface of the construction site One or more twisted supply lines can be installed and then mounted thereafter outlets or bypass blocks as needed near the user's premises Or a twisted power line can be pre-equipped from a series of spaced outlets before it is installed on the

  to provide a twisted power line at fixed intervals

  in congested or heavily trafficked areas

  connection and connection to luminaires.

  The device of non-halogenated material can naturally be formed for applications where fire safety is essential, such as tunnels, subways, pedestrian galleries, etc.
