Abstract

Device to swage a sleeve (7) on a cable (8) comprises two half bodies (1,2) with recesses (3,4) and cooperating pins (5,6) to attach them together. Once the two half bodies assembled they are forming a housing, whose section is smaller than the cable section.

Description

The invention relates to a device for shrinking a sleeve on cable to ensure the connection between the sleeve and the Gable.

The connection of cables end to end or on a support is traditionally carried out using a tubular sleeve threaded and then compressed on the cable. The operator must proceed by successive small offset passes with partial overlap of the passes, which bends the connection made.

The use of sleeve holding devices during the operation does not eliminate the risk of making a curved connection.

The device according to the invention overcomes this drawback. According to a first characteristic, it comprises a set of two half-bodies defining a closed profile opposite, for example and without limitation a hexagonal profile, of section smaller than the section of the initial profile of the sleeve threaded on the cable. Each half-body has housings capable of receiving guide forms integral with the half-body opposite. When the operator compresses the sleeve between the half-bodies to ensure its constriction on the cable, this guidance maintains, at each compression pass, the coaxial half-bodies guaranteeing the final straightness of the connection.

According to the particular embodiments - The guide shapes can constitute a part of the half-bodies.

- The reception housings can be attached to the half-bodies - A half-body can group together the guide shapes, the half-body opposite then grouping together the reception housings.

The accompanying drawings illustrate the invention - Figure 1 shows in section the device according to the invention. - Figure 2 shows in section a variant of the device according to the invention. - Figures 3, 4, 5 and 6 show in section the realization of the constriction by the device.

Referring to Figure 1, the device comprises two half-bodies (1) and (2) defining opposite closed profile section lower than the initial section sleeve (7) to be constricted on the cable (8). Each half-body has housings (3) and (4) capable of receiving guide shapes (5) and (6) integral with the half-body opposite. The sleeve (7) is constricted on the cable (8) the approximation printed by the operator of the half-bodies (1) and (2) towards one another. The lengths of the guide shapes (5) and (6) and of the housings (3) and (4) are such that the half bodies (1) and (2) are positioned relative to each other before and during the shrinking phase the sleeve (7) the cable (8).

In the embodiment according to FIG. 2, the housings (3) and (4) are placed on the same half-body (1) the guide shapes (5) and (6) are placed on the half-body (2) .

According to a variant not illustrated, the guide shapes (5) and (6) can constitute part of the half-body (1) or (2).

According to another variant not shown, the receiving housings (3) and (4) may consist of elements added to the half-body (1) or (2).

The device according to the invention is particularly intended for work of fitting fittings on overhead line conductor cables.

Claims (4)

1) Device for shrinking a sleeve (7) threaded on a cable (8) characterized in that it comprises two half-bodies (1) and (2) defining opposite profile section smaller than the section of the initial profile of the sleeve (7) and equipped with housings (3) and (4 able to receive guide shapes (5) and (6) positioning the half-bodies (1) and (2) relative to each other when operator compresses the sleeve (7) between the half-bodies and (2). 2) Device according to claim 1 characterized in that the housings (3) and (4) are placed on one of the half-bodies (1) or (2) and the guide shapes (5) and (6) are placed on the other half-body respectively (2) or (1). 3) Device according to claim 1 or claim 2 characterized in that the forms of guides constitute a part of the half-body (1) or (2). 4) Device according to claim 1 or claim 2 or claim 3 characterized in that the receiving housings consist of elements attached to the half-bodies (1) or (2).
