Description

Electrical connection device and method for its ndse in action

The present invention relates to a 61ectrique connection device and a proc6d6 for its implementation.

The electrical connection device according to the invention is characterized in that it comprises a flexible clamping member having a bar and side walls starting from this base and a rigid intermediate member intended to be placed between these walls, means intended to allow this spacer element to be moved by the clamping member and constituted by at least one magnetic discontinuity on the surface of at least one of these. organ and 61ement, so that a force can be applied between the clamping member and the intercalary 616ment.

The invention also relates to a proc6d6 for the actuation of the device, characterized in that introdui.t of. conductors between. side walls. of the clamping member, place the spacer 1'616ment between these conductors and apply a force between the clamping member and a discontinuity provided on the spacer 1'616ment to push it back between these conductors and these walls. side.

The appended drawing represents, by way of example, one form of execution of the object of the invention. fig. 1 is a plan view of this embodiment; fig. 2 is a top view; fig. 3 is a plan view of a spacer; fig. 4 is a vertical sectional view along line 4-4 of FIG. 3; fig. 5 is a plan view of the device during its actuation;

fig. 6 is a side view of the device at the moment of its actuation with the aid of a pair of pliers, and FIG. 7 is a side view of the device when it is activated using a screwdriver. The device represented in FIGS. 1 to 4 comprises a clamping member 10 whose section has the shape of a flattened U with a slightly arcuate base, from which a pair of semi-circular side walls 11 and 13 originate. The side walls 11 and 13 are intended to receive conductors 14 and 16. The clamping member 10 is .in a conduoteur metal presenting properties. 61astic such that when arms 11 and 13 are dormed they tend to return to their initial shape and position. This member can, for example, be made of T.N. 245 Die Aluminum Company of America (page 817, Metals. Handbook of the American Society for Metals, Edition 1948).

An intermediate element 12 is associated with the clamping member 10. This intermediate element 12 has an edge. slightly tapered 20 joining behind at parallel sides. The parallel sides may be fluted and curved so that the conductors 14 and 16 fit between the side walls of the spacer 12 and the arms 11 and 13 of the clamp 10. The spacer 12 presents on its surface a series of discontinuities 22, 24, 26, 28 and 30. These discontinuities can be hollow or raised.

In service, the conductors 14 and 16 which can be of different sizes, the first being for example a main conductor and the second an auxiliary conductor, are arranged in the housings formed by <B>k</B>s arms 11 and 13 of the channels of the clamping member 10. The tapered end 20 of the 1'616-

interlayer 12 is introduced between the cables and slides along them. The dimensions of the clamp 10 and the spacer 12 are so determined that when the cable and spacer are inserted between the arms 11 and 13, they force the arms open, which, then their elasticity, firmly clamp the conductors 14 and 16 against the spacer 12. The spacer 12 could be wedge-shaped and tapered. Such a configuration does not give rise to a strong uniform grip over the entire length, but it is sufficient in many cases.

To slide spacer 12 between conductors 14 and 16, clamping member 10 has a discontinuity 18 on its outer surface. This discontinuity may take the form of a bump, a depression or an orifice in the surface. If the discontinuity 18 is formed by a boss or an orifice, an effort can be exerted using a pair of pliers, 38 of which an applies the jaws 40 and 42 between a wall of the discontinuity 18 and a wall of the gaps 22, 24, 26, 28 and 30 of the intermediate element 12. It is obvious that it is possible, when the jaw 42 is closed, to open it again and bring it into the next discontinuity of the intermediate element, by thus progressively advancing the latter between the conductors.

Alternatively, as shown in FIG. 7, when the discontinuity 18 of the clamping member 10 is formed by a hole, a screwdriver 36 can be inserted therein and use one of the walls of the hole as a point of support for the screwdriver used as a lever. .

It is obvious that the interealasre 1'61.6ment 12 can have only one discontinuity and that the clamping member can be provided with a series of holes so that the first screwdriver can be inserted Jans 1st First hole of 1 ' clamping member and move the discontinuity of the intermediate element 12 along the longitudinal axis of the clamping member until the screwdriver can be introduced into the next hole and thus cause this element to assume its different successive positions.
