The points which are generally a copper alloy and may be conical, flat or threaded, ensure electrical contact. The internal size of the channels are manufactured according to the norms of cable diameters to ensure a tight fit. USE/ADVANTAGE - Connection of two single wires, several cables, extension of cables, shunting. No tools required, quick operation.

Description

CONNLTMR AR @ OCHES FOR LINKS, BYPASSES AND FITTINGS
FHS OR CASDES CONDUCHES OF ELECIRICHE
The present invention relates to an electrical connection device for connecting wires or cables to one another and thus allowing transmission or bypass of the current between the transducers.

 These connections are traditionally defined by a device comprising screws which hold the conductors inside an insulating box.

These very widespread connectors require the use of divwers, cutter screwdrivers, wire strippers ...; and in particular the preparation of wires or cables by the systematic creation of a splice or a stripping of the insulating sheaths of these wires; therefore involving numerous manipulations.

 The device according to the invention allows to overcome these drawbacks. It indeed comprises, according to a characteristic remère, a body made up of insulating material in which are inserted metallic relatives having sharp points. These pins. of which only the points protrude inside of grooves in which the wires to be connected will be placed, allow the transmission of the current when by pressure the sharp points penetrate into the conductor of the wire through the protective sheath of this cable.

 The body of the device is manifactured in its dimensions, in particular internal, so that the different dimensions are related to the standards of wires or cables which it is worth connecting. Indeed, the device by its shapes will come very tightly and securely close around the cables so that the tips of the pins penetrate by the pressure exerted on the window, in conductors generally made of copper alloy.

 The body of the device is according to another characteristic, composed of two parts articulated by a hinge, obtained according to the falxication mode, by the small thickness of material at this location, allowing, thanks to its flexibility and elasticity, to articulate the das parts constituting the body of the invention.

 The booches embedded in the mass are arranged in the axis of the caes of the grooves intended to receive the cables and in particular so that their points protrude sufficiently to reach during penetration, the conducting element of these cables.

 According to the particular embodiment, a simple pressure of the fingers is enough to close the device on the cables or wires to be connected; by clipping its parts into a dovetail type system, playing on the elasticity of the material.

 The closure of the device ensures, in addition to the desired connection, the solidity of the connection of the wires, by the penetration of the tips of the pins and the constant pressure of the body of the device on the cables, which it maintains tightly by slight crushing and circulation, by its dimensions which con has mentioned above the relationship with those of the cables and again by the shape of its bitted ends, which pinch the said cables or wires more.

 According to another characteristic, the cables, which it suffices to cut braidedly, will be positioned in the hollow of the grooves in abutment on an extra thickness made at the median axis of the body of the device.

According to particular embodiments:
-The device can in the above conditions, and its adaptations, ensure the connection of one type of cable or wire to several others, thus multiplying the outputs or phase inputs for example, neutral, grounding or other transmission as required.

 -The device in the case of cables with several conductors, can be adapted individually to each of the conductors, so as to allow the multiple combinations desired, such as simple extension of cable by junction, or branching into several cables.

 -The pins of the device can be inserted in only one of the two parts constituting the invantion.

 -The pins can be of various shapes, cylindrical, flattened, square section or any other and can have conical points or any other shape permitting penetration.

The accompanying drawings illustrate the invention:
Plate 1/1:
Figure 1 shows a longitudinal section of the invention in its adaptation to a cable daux conducxteurs.

 Figure 2 shows the cross section of the same adaptation of the device.

 Figure 3 shows the uve section from the top of the same adaptation.

 Figure 4 shows a perspective of the invention without the positioning of the wires for clarity6.

Plate 2/2:
FIG. 5 very schematically represents the case of a connection adaptation between a cable with two conductors with two cables of the same type.

FIG. 6 represents the schematic section of the case of FIG. 5.
FIG. 7 represents the individual connection of the conductors of a cable with three conductors in those of a simple extension.

 FIG. 8 represents the individual connection of the conductors of a cable with three conductors in the case of a double extension.

 With reference to these drawings, the device comprises a body (2), into which are inserted pins (1), penetrating by pressure into the conductors (6) through their sheaths (5).

The wires are positioned in abutment on an additional thickness (3) in housings in the form of grooves (9) and are held by crushing, more particularly at the bevelled ends (4) of the device.

 The two parts forming the body of the device are articulated by a hinge (8), formed by the small thickness of material at this location.

 The two parts are closed by male-female interlocking of the dovetail type.

 According to these principles, Figures 5,6,7,8, are examples and demonstrate that the adaptations of the device can be numerous and in no case limited to the representations of the appended figures.

Important:
No scale has been respected in the figures and the general proportion of the ratings does not refer to any reality. Indeed, as stated in the characteristic, the dimensions of the device vary according to the standards of the wires or cables to which they adapt in different configurations of desired connections.

 The device according to the invention is therefore particularly intended for the connection of electrical wires and cables.
