ABSTRACT:
DESCRIPTION
1. Field of the Invention
The invention relates to a wedge connector with insulation perforating device, for connecting electrical conductors provided with an insulating covering, comprising: [a] an external C-shaped member, determining two first curved wings, the respective bottoms of which define mutually inclined longitudinal lines; [b] a wedge member having two mutually inclined concave active edges; and [c] at least one intermediate member comprising electrically conducting material and which is adapted to be located between said external member and said wedge member.
2. Prior Art Reference
Document EP 0 810 688 describes a connector for obtaining an electrical bridge between two electrical conductors having an insulating covering. This bridge is based on an electrically conducting intermediate member provided externally with perforating means which may be applied to portions of two insulated conductors, located respectively in the wings of the external member. The insertion of a wedge in the intermediate member causes the engagement of these perforating means with the insulating covering and the consequent establishment of an electrical connection between both conductors.
Nevertheless, this connector has the drawback that it allows a large relative sliding between the conductor and the perforating means, whereby it frequently causes serious tears in the insulating covering, which is an unfavourable circumstance as far as obtaining a long-lasting connection is concerned.
SUMMARY OF THE INVENTION
It is an object of the invention to overcome the abovementioned drawback. This object is achieved with a connector of the type first mentioned above which is characterised in that said intermediate member has a plurality of perforating teeth and surrounds in part at least one portion of a conductor disposed between said wedge member and said intermediate member.
The invention also contemplates that said intermediate member is C-shaped and forms two second curved wings between which there extends a generally flat portion. Each of said two second curved wings is adapted for surrounding in part a portion of one of said electrical conductors and each of them is provided with said perforating teeth projecting internally from the concave surface thereof.
Said perforating teeth preferably form pairs of teeth, in such a way that both teeth of one same pair project from respective facing longitudinal portions of a wing, in which there is formed an opening.
According to another preferred feature of the invention, in the longer transverse edge of said flat portion of said intermediate member, there extends a stop member formed by a fold, which by engagement with a transverse edge of said external member, is adapted to limit the sliding of said intermediate member relative to said external member.
