Furthermore, in the context of the present description, it will be considered that all elongated objects will have an implicit “longitudinal axis” or “centerline”, such as the longitudinal axis of a line for example, or the centerline of a bore, for example, and that expressions such as “connected” and “connectable”, or “mounted” and “mountable”, may be interchangeable, in that the present invention also relates to a kit with corresponding components for assembling a resulting fully assembled and operational wedge cartouche (and/or at least one line including the same).
Moreover, components of the present system(s) and/or steps of the method(s) described herein could be modified, simplified, altered, omitted and/or interchanged, without departing from the scope of the present invention, depending on the particular applications which the present invention is intended for, and the desired end results, as briefly exemplified herein and as also apparent to a person skilled in the art.
In addition, although the preferred embodiments of the present invention as illustrated in the accompanying drawings comprise various components, and although the preferred embodiments of the wedge cartouche and corresponding parts as shown consist of certain geometrical configurations as explained and illustrated herein, not all of these components and geometries are essential to the invention and thus should not be taken in their restrictive sense, i.e. should not be taken so as to limit the scope of the present invention.

Optionally also, and as can be easily understood when referring to the accompanying drawings, the front transversal section (87) is provided with a protruding edge (89) for abutting against a corresponding outer slit (91) of the first wedging component (7a) of the wedge cartouche (1).
Additionally, the front section (71) of the handle assembly (65) may comprise a foldable tab (93) operable between opened and closed configurations, the foldable tab (93) being configured for selectively folding in front of the groove (85) of the front section (71) of the handle assembly (65) in order to maintain the retaining pin (43) in said groove (85) of the front section (71) of the handle assembly (65) when operated in the closed configuration.
The foldable tab (93) may be further configured to be removably maintained against the front section (71) of the handle assembly (65), in the closed configuration, via an interlocking assembly (95).

In contrast, the first and second wedging components (7a,7b) of the wedge cartouche (1) are preferably made of a metallic material, such a stainless steel or aluminum (ex. for better electrical conductivity, when desired), for example, although other suitable materials are also contemplated for the present wedge cartouche (1).
Preferably, handle assembly (65) is made of a color different than that of the at least one wedging component (7), whether the first and/or second wedging components (7a,7b), in order to enable a user of the wedge cartouche (1) to visually determine at a distance whether or not the handle assembly (25) is mounted onto the wedge cartouche (1).
As may now be better appreciated in view of the above description, the present wedge cartouche (1) is advantageous in that it consists of a competitive wedge-tap which is easier and faster to install then other products known to the Applicant. Moreover, the present wedge cartouche (1) is also advantageous over conventional systems in that a user thereof, does not need to require the use of any specific tools for the installation of the wedge cartouche (1). Indeed, the present wedge cartouche (1) is preferably designed to be “self-sufficient”.
As previously explained, the present wedge cartouche (1), also referred to as “wedge-tap”, may consist of at least two different parts, namely the main body, referred to herein as the containment assembly (5), and the center wedge cartouche or “wedge assembly”, which according to a given embodiment, is filled with a blank cartridge (17).
As also explained herein, and as can be easily understood when referring to the accompanying drawings, a possible manner in which to use the present wedge cartouche (1) is simplified with respect to other conventional systems known to the Applicant.
The way it works can be essentially summarized as follows: inside the wedge assembly, there is a blank cartridge (17) filled with a specific amount of explosive powder (19) taken in a barrel (23) or a canon. This assembly is inoperative and stable until the retaining pin (47), which could simply consist of a conventional nail (51), for example, is removed from the striker (37), after which, this action releases the spring (51) and propels the striker (37) onto the primer (21) of the blank cartridge (17). The shock between the striker (37) and the cartridge (17) results in an explosion or burst of the blank cartridge (17) which builds a pressure zone inside the barrel (23) or canon. As a result thereof, the upper part of the wedge cartouche (1), that is, the top wedging component (7a) is propelled in the canon axis. Consequently, the cables (3) are now tightened against the main body (5a) of the containment assembly (5), and against upper and lower gripping portions (63) of the wedge assembly.
Referring to
As can be easily understood, the present wedge cartouche (1) provides several advantages over conventional systems, in that, as mentioned earlier, it is a product that does not need any specific tool for its installation. It is also advantageous that it is very fast to install. By virtue of its design, the product is meant to be easily installed at a proper position within the containment assembly (5). The product is also safe to use, in that, there is little or no noise, and no projectile, and also, no specific licence is required due to the use of blank cartouches, etc.
The present wedge cartouche (1) has also been designed to be safe when manipulating in that the handle assembly (65), is a safety component that the handle (97) cannot be removed during manipulation.
Furthermore, as can be easily understood when referring to
Thus, in view of the above, and as may now be better appreciated, the present wedge cartouche is advantageous over other related wedging devices and/or methods in that it enables to wedge a portion of at least one line (and/or to wedge at pair of power lines together for an electric connection thereinbetween, for example) in a simpler, easier, faster, cleaner and/or more convenient manner than what is possible with other conventional systems.
Finally, and as can be easily understood, the present wedge cartouche (1) and corresponding parts can be made of substantially rigid materials, such as metallic materials, hardened polymers, composite materials, and/or the like, as well as other possible combinations thereof, depending on the particular applications for which the tensioning assembly (1) is intended, and the desired end results.
Of course, and as can be easily understood by a person skilled in the art, the scope of the claims should not be limited by the possible embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
