Definitions
- This invention relates to a top clamp of the kind that includes a housing, suitably made of plastics, whose one end is open whilst the opposite end is closed by means of an end wall, a device for the twisting and the connection of conductors being arranged inside the housing.
- Top clamps of the kind related above are above all used for the connection of insulated conductors,having one or several leads,inside conduit boxes that can be recessed in walls or ceilings. More specifically,the connection is done thus that the insulation is stripped from the lead-ends of the conductors arriving in the conduit box and that are intended to be connected, where ⁇ upon the thus stripped lead-ends arebrought together to a bundle onto which a top clamp is applied which is rotated a plurality of turns, the in the inside of the top cla located twisting device -that in practice consists of a conically tapering thread provided metal sleeve - effecting an efficient twisting and by those means a permanent connection of the leads.
- the present invention aims to remove the above-mentioned drawbacks and to create a top clamp that not necessarily must be turned manually by the operator.
- the top clamp according to the invention is primarily characterized in that on the outside of the end wall a projection is arranged having a cross-sectional form, preferably a hexagonal cross-sectional form, corre- sponding to the cross-sectional form of a rotatable socket in per se known power actuated nut tighteners.
- FIG. 1 is a perspective view illustrating how a top clamp made in accordance with the invention can be made to rotate by means of a nut tightener in order to twist a plurality of conductors in a conduit box
- Fig 2 an enlarged perspective view showing a top clamp made in accordance with the principle of the invention.
- FIG. 1 designates a top clamp that r in a per se known manner,comprises a suitably conically tapering,plastic housing 2 into which an also conically tapering thread-provided metal sleeve 3 has been pressed.
- the plastic housing 2 is open at its larger end 4 whilst the narrower end is closed by means of an end wall 5.
- On the outside of the housing 2 two diametrically opposed wings 6,6' are formed /intended to facilitate the turning of the housing by means of the fingers of the hand.
- a projection 7 with an appropriate length, i.e. 2-6 mm, is formed on the outside of the end wall 5 and in this case having a hexagonal cross-section. More specifically,the cross-sectional form of this projection 7 corresponds to the cross-sectional form of a rotatable socket 8 in- eluded in a nuttightener of a per se known,suitably battery powered kind, in Fig 1 generally designated with 9.
- Fig 1 10 further denotes a conduit box whereto a plurality of different electric conductors 11 are brought together.
- the socket 8 is applied onto the projection 7 of the top clamp and the nut tightener 9 is started.
- the socket will then bring the top clamp into rotation whilst twisting the conductors in a per se known manner (for the sake of clarity the top clamp is shown separated from the conductors in Fig 1, although • in practice these after said rotation are closely connected to the metal sleeve 3) .
- the too clamp in question thus, by means of the projection 7, can be simply and quickly connected to,optional and/or known power actuated nut tighteners,thus eliminating all need or a manual turning by the operator.

Abstract
Un serre-fils de plafond comprend un logement (2) en plastique dont une extrémité (4) est ouverte tandis que l'extrémité opposée est fermée au moyen d'une paroi d'extrémité (5), un dispositif (3) permettant de torsader et de connecter les conducteurs étant agencé à l'intérieur du logement. Un élément en saillie (7) agencé à l'extérieur de la paroi d'extrémité (5) possède une forme de section transversale correspondant à la forme de section transversale d'une douille rotative dans un dispositif de serrage d'écrou à commande électrique connu en soi.
