FR2571899A1 - Connectors for electricity-conducting wires or cables - Google Patents

Abstract

The present invention relates to connectors for electricity- conducting wires or cables permitting connections without stripping the wire or cable. It comprises a non-conducting block 1, one or more grooves 2 on at least two faces. A fine point 3, inside the grooves 2, provides the electrical connection between two opposing grooves and serves to impale the electrical wire or cable. The interior of each groove 2 may or may not be coated with an adhesive material 4 as well as with one or more asperities 5 in the form of flexible hooks pointed inwards. Among the most useful applications, mention may be made of the connection of two wires or cables without removing the protective sheath.

Description

The present invention relates to wire connections or electrically conductive targets of the "domino" type.
In known devices of this type, the connections of wires or electrically conductive targets are made, for example, by means of "dominoes".

The wires or targets are stripped and then introduced into an electrically conductive groove and held in place by crushing using a screw. They are coupled to allow the passage of electric current.

This operation requires the stripping of the wire or cable with the risk of electrocution that this operation involves in case of negligence. It also requires the use of a screwdriver to lock the wire, as well as a sharp knife-type or wire stripper, for example. ue more, in the case where one or more wires come to detach from the fitting, these being aenuaes, there is a risk of short circuit.

ne connection of son or cables electrically conductive according to the invention consists of a block of non-conductive plastic or other material, having on at least two sides one or more grooves coupled in pairs.

 @ inside each one there is a fine point in @atiere conductive of electricity which will aim to ensure the electrical transmission between two wires or cables, and by the impaling process to make penetrate this fine point to the inside the wire or target without the need to strip it.

melon a second variant it can be applied to the walls of the groove with a flexible adhesive material allowing the sheath to be fixed to the wire or cable to the support.

According to a third variant, the interior of the groove may be equipped with one or more asperities in the form of fangs, for example, pointed inwards in semi-rigid material, which can bend when the wire or cable is introduced, and to prevent its removal.

In the event of one or more wires or targets dropping out, the possibility of a short circuit is highly improbable since the wires or cables are not stripped for use.

The present invention allows a quick connection of two wires or cables with greater security for the user since it does not require the removal of the protective sheath.

The invention will be better understood during the description given below by way of purely indicative and nonlimiting example which will aten identify the advantages and the secondary characteristics.

reference will be made to the accompanying drawing.

ba figure @ is a diagram representing the invention in the form of an element in non-conductive material (I) of electricity. I1 is provided with at least two grooves (2) opposite, having inside a point (3) serving as transmission. On the walls of the groove (2) an adhesive material (4) can be put as well as a fine point (5) in the form of a hook, for example, biased inwards to prevent the wire from being withdrawn. .

The device which is the subject of the invention can be used in all cases where it is necessary to connect two electric wires together.

Particularly interesting applications may be envisaged in the field of electricity.

Claims (4)

 CLAIMS.  I. Connections of wires or electrically conductive targets in the form of a block (I) of non-conductive material having on one or more of its faces one or more grooves (2) pairs in pairs, characterized by the fact that 'inside each groove (2) is a fine point (3> allowing after introduction of the wire or cable the transmission of electric current from one groove to another.  2. Fittings according to claim (I) characterized in that the contact between the electric wire or cable and the fitting is obtained by impaling the wire or target on the tip. (3)  3. Fittings according to claim I characterized by the presence on the walls of the groove (2) of an adhesive material (4) used for fixing.  4. Fittings according to claim (1) characterized by the presence on the walls of the groove (2) of one or more asperities (5) used for fixing.
