Description

DEVICE FOR THE ELECTRICAL INTERCONNECTION OF CABLES
Technical Field
The present invention relates to a device for the interconnection of cables and other electrical components required for wiring operations.
Background Art
The devices commonly used for the interconnection of electrical cables and other elements, e.g. connection cable-heads, electrical sockets and the like, have a connection body in which the elements to be connected can be inserted.
Inside the connection body are connection means provided with special conductor bodies adapted to electrically connect the electrical components after a breakage of the insulating enclosure of the components themselves.
The connection body can be inserted in a protective outer enclosure, e.g. provided with cable gland means adapted to prevent the transmission of tensile forces to the extremities of the components connected to one another.
A known type of device for the interconnection of cables and other components has a connection body placed between two guiding portions in which the components to be electrically connected can be inserted.
With the connection body are associated conductor bodies provided with fork incision extremities adapted to interact with the electrical components to be connected.
The guiding portions can be moved close to the connection body so as to press the electrical components against the incision extremities in order to make a cut on the insulating enclosure of the components themselves and thus create the electrical connection.
A drawback of this type of known device is linked to the breakage of the insulating enclosure, required to create the electrical connection between the components.
Known devices, in fact, are provided with fork-shaped, sharp conductor bodies, in which the components to be connected can be pressure-fitted.
The forks cut through the insulating enclosure and come into contact with the conductor wires inside the cables.
This solution does not guarantee a perfect connection inasmuch as breaking by cutting or incising the outer enclosure allows obtaining a shallow contact area, often insufficient to create a stable and effective contact.
Furthermore, cuts or incisions made on the enclosure tend to expand over time, exposing the conductor wires, increasing power losses and the risk of malfunctioning.
This latter possibility can assume greater relevance in the event of the device being accidentally infiltrated with water.
In this case, contact between the wires exposed by the incision and the water would cause damage to the entire electrical system.
Description of the Invention
The main aim of this invention is to provide a device for the interconnection of cables and other electrical components which allows the effective and safe interconnection between the components.
One object of this invention is to provide a device for the interconnection of cables and other electrical components which is able to maintain its functionality over time.
A further object of the present invention is to provide a device for the interconnection of cables and other electrical components that is able to minimize the risk of contact between electrical wires and water or other liquid substances.
Another object of the present invention is to provide a device for the interconnection of cables and other electrical components that allows overcoming the aforementioned drawbacks of the prior art within the scope of a simple, rational, easy, efficient to use and cost effective solution.
The aforementioned objects are achieved by the present device for the interconnection of cables and other electrical components having the characteristics of claim 1.

Embodiments of the Invention
With particular reference to these illustrations, reference numeral 1 globally indicates a device for the interconnection of cables and other electrical components.
The device 1 comprises a substantially cylindrical connection body 2 and having at least one insertion seat 3.
In particular, the connection body 2 comprises a first portion 4 and a second portion 5, comprising respective insertion seats 3, associated with one another to form a prismatic coupling.
Moreover, the connection body 2 comprises a locking ring nut 6 associated with the first portion 4, but the solution cannot be ruled out in which it is associated with the second portion 5.
The ring nut 6 can be screwed onto the first portion 4, thus allowing the tightening of the connection body 2.
The device 1, conveniently, comprises at least one slider element 7 associable with at least one cable 8 to be electrically connected, the slider element 7 being inserted in the insertion seat 3 along a sliding direction and carrying the cable 8 close to the connection body 2.
Conveniently, the sliding direction is substantially parallel to the cylindrical axis of the connection body 2.
The slider element 7 carries the cable 8, associated therewith, to the insertion seat 3 into contact with the bottom of the seat itself.
Advantageously, the slider element 7 comprises at least one guiding duct 9 adapted to position the cable 8 for its approach to the connection body 2.
A user can place or insert the cable 8 in the guiding duct 9 in order to insert the slider element 7 into the insertion seat 3 and thus carry the cable into contact with the bottom of the seat itself.
The guiding duct 9, in fact, comprises a proximal section 10 proximal to the connection body 2 facing the connection body itself, thus allowing the positioning of the cable 8 in the proximity of the connection body 2.
The device 1 comprises at least one connection element 11 inserted in the connection body 2 and adapted to come into contact with the cable 8 to make an electrical interconnection.
According to the invention, the connection element 11 comprises a perforating extremity 12 that extends in the insertion seat 3.
The perforating extremity 12 is substantially pointed and is adapted to penetrate into the cable 8 when this is approached to the connection body 2 by the slider element 7.
Therefore, when the slider element 7 is inserted in the insertion seat 3, the cable 8 brought by the guiding duct 9 is pressed against the perforating extremity 12 which penetrates it, perforating the insulating enclosure of the cable itself and coming into contact with the conductor wires generally contained inside the enclosure.
In the present embodiments, the connection element 11 is of the type of a conductor bar provided with two conductor portions interlocked into one another, but different solutions cannot be ruled out, e.g., conductors in a single body piece.
Advantageously, the device 1 comprises at least one gasket element 13 co- molded on the connection body 2 and surrounding at least partly the same connection body 2.
The gasket element 13 is made of polymeric material and has the function of ensuring the water tightness of the device 1 in the zones where several elements are joined together, e.g., in the area of contact with the ring nut 6. The device 1 also comprises a cable gland assembly 14, 15 screweable onto the connection body 2 at the insertion seat 3 and interacting with the cable 8 for the reduction of tensile forces exerted on the same cables.
The cable gland assembly 14, 15, in fact, counteracts the tensile forces adapted to move the cables 8 away from the connection body 2.
The cable gland assembly 14, 15 comprises a supple portion 14, made of a supple polymer material, wrapped around the cable 8, and a compression extremity 15, containing the supple portion 14 and which can be screwed onto the connection body to compress the supple portion 14.
Such compression on the supple portion 14 makes it possible to counteract the tensile forces, thus preventing the cable 8 from coming off the connection body. The compression extremity 15 comprises a first part 16 which can be screwed onto the connection body 2 and a closing cap 17 which can be screwed onto the first part 16.
In the present embodiments, the devices 1 illustrated comprise at least two insertion seats 3, of which a first seat 3 a and a second seat 3b arranged at the ends of the connection body 2.
The two seats 3a, 3b are positioned symmetrically with respect to the central axis which divides orthogonally the connection body 2.
The devices 1 illustrated also comprise at least two slider elements 7 of which a first slider 7a inserted in the first seat 3a and a second slider 7b inserted in the second seat 3b.
The first slider 7a and the second slider 7b carry respective cables 8 of which a first cable 8a carried by the first slider 7a and a second cable 8b carried by the second slider 7b.
The slider elements 7a, 7b illustrated also comprise a plurality of guiding ducts 9 adapted to position a plurality of first cables 8a or of second cables 8b, so as to allow for a multi-polar interconnection.
The devices 1 illustrated comprise a plurality of connection elements 11, one for each first cable 8a and each second cable 8b to be connected.
In particular, each connection element 11 comprises at least two perforating extremities 12 of which a first extremity 12a which extends in the first seat 3 a to perforate a first cable 8a and a second extremity 12b which extends in the second seat 3b to perforate a second cable 8b.
Furthermore, the devices 1 shown also have two gasket elements 13 and two cable gland assemblies 14, 15.
The gasket elements 13 are interposed between the cable gland assemblies 14, 15, placed at the extremities of the connection body 2, and the ring nut 6, placed substantially at the center of the connection body 2.
This way, by screwing up the cable gland assemblies 14, 15 and the ring nut 6, the gasket elements 13 are pressed, thereby ensuring the water tightness of the device 1.
In a first embodiment illustrated in Figures 1 to 3, the device 1 comprises six connection elements 11 with respective first extremities 12a and second extremities 12b.
Each of the slider elements 7a, 7b has six guiding ducts 9 adapted to carry respective cables 8a and 8b, so as to make a six-pole connection.
Advantageously, each guiding duct 9 comprises a proximal section 10 proximal to the connection body 2 substantially orthogonal to the relative perforating extremity 12.
This way, the cable 8 is perforated on its lateral surface, allowing the penetration of the perforating extremity 12 orthogonal to the direction of extension of the cable itself.
In a second embodiment shown in Figures 4 and 5, the device 1 comprises three connection elements 11 with respective first extremities 12a and second extremities 12b.
Each of the slider elements 7a, 7b has three guiding ducts 9 adapted to carry the respective cables 8a, 8b so as to make a three-pole connection.
Advantageously, the guiding duct 9 comprises a proximal section 10 proximal to the connection body 2 substantially parallel to the perforating extremity 12. This way, the cable 8 is perforated in the section transversal to the direction of extension of the cable itself, thereby allowing the axial penetration of the cable. The operation of the present invention is as follows.
The cables 8 to be connected are inserted into the slider elements 7 and made to run along the guiding ducts 9.
The slider elements 7, with the cables 8 in position, are inserted into the insertion seats 3 until the proximal sections 10 come into contact with the connection body 2.
The sections of cables 8 positioned in the proximal sections 10 are pushed onto the perforating extremities 12 which extend into the insertion seats 3, causing the perforation of the insulating enclosure containing the conductor wires of the cables themselves.
By screwing up the ring nut 6 and the cable gland assemblies 14, 15, the connection body 2 is tightened and the cable gland assembly 14, 15 is operated. In the first embodiment, the six cables 8a and the six cables 8b are brought into contact with their respective extremities 12a, 12b through the proximal section 10 orthogonal to the extremities themselves.
This way, a six-pole interconnection is obtained with penetration of the lateral surface of the cables.
In the second embodiment, the three cables 8a and the three cables 8b are brought into contact with their respective extremities 12a, 12b through the proximal section 10 parallel to the extremities themselves.
This way, a 3 -pole interconnection is obtained with axial perforation of the cables to be connected.
Embodiments other than those illustrated cannot be ruled out, e.g. in which there is a number of cables to be connected in a different manner.
It has in practice been ascertained that the described invention achieves the intended objects and, in particular, the fact is underlined that the device provided for the interconnection of cables and other electrical components allows an effective and safe interconnection between the components.
Penetration through the pointed extremity does in fact allow an effective connection, inasmuch as the extremity penetrates deeply, ensuring an optimal and safe connection, inasmuch as there are no potentially dilatable cutting zones such as to become exposed areas.
The particular assembly of the device by means of the ring nut and the co- molded gaskets allows maintaining the functionality of the device over time. Furthermore, the device thus provided allows minimizing the risk of contact between electrical wires and water or other liquid substances, both thanks to perforation by means of the pointed extremity, and thanks to the use of co- molded gaskets aimed at ensuring the water tightness of the device.
The device, therefore, ensures a high degree of water tightness and protection of the electrical connections from malfunctions due, e.g., to infiltrations of water inside the device itself once this has been assembled.
