    The invention described above of this connector for the splicing of electric cables allows the secure connection between electric conductors, whether or not they are of the same section. The safety is provided by the material that is electrically insulating, that can not be in accidental contact with any driver, that does not have metallic elements with which we can make contact and that the unión is durable and will not be released after some time. This joint solution was proposed with the intention of being safer, but also more convenient and simple to splice cables, without having to use tools such as screwdrivers and can do them in inaccessible places. It is also a cheap solution, because of its economic manufacture, reduced raw material quantity, absence of mechanized elements and only 2 or three sets of male-female connectors are needed to cover the needs, number of conductors to be connected as different sections of cables to join.

    DESCRIPTION
    CONNECTOR FOR THE ELECTRICAL CABLES PACKING SECTOR OF THE TECHNIQUE
    The present invention deals with a connector for splicing electrical cables, whether multifilament or rigid copper cable (regardless of the cable sheath), consisting of two pieces, a male and another female, which, when fitted between them, allows The clamping of the cables to be spliced, prevents contact with the conductive cables and reuse is possible by disassembling and mounting it on different occasions. In addition, no tools, such as screwdrivers, are necessary to make the connection.
    For years, as a more usual method, systems such as electrical connection strips, consisting of a body of insulating or dielectric material, equipped inside a conduit or metal bushing, of tubular configuration, have been used for these joints. and necessarily having two threaded upper holes for, in combination with some thymes housed in the upper insulating element, to achieve the clamping of the conductive cables inside the conduction or aforementioned bushing.
    This last system described presents several drawbacks, first of all the considerable cost of the set, to which the requirement of mechanized driving or internal bushing, the assembly required by means of tools such as screwdrivers, mainly that are numerous cases where it is caused the cutting of the different wires of the conductor cable, and can even lead to faulty connections by accidental separation of these. Another safety problem presented by systems similar to this one is that it is possible to come into contact with the screws or metal fasteners, with the consequent danger of electric shock.
    Other systems, such as the splice called "rat tail" do not offer splice security, since the protective cap can be released or the splice is in the air, without protection. And using a connector or cap that protects it, it is likely that over time, this cap will come loose or not completely cover the conductors. Forcing to use electrical tape to protect that joint.
    image2
    Screwless systems have been created for the imprisonment of the conductors, but that forces a more complex design of the insulating body, with its consequent price increase.
    Another general drawback in existing systems is that they require several models to be used depending on the diameter of the conductor or the number of conductors to be spliced. For the
    10 which, by increasing the section of some of the cables or adding conductors to the joint, due to an extension or improvement of the electrical installation, causes having to use another joint model of greater or lesser size, as appropriate. Due to this it is necessary to have several models of joining systems to choose the chord to the union to be made.
    15 A correct and ideal splicing element, has to perform just that function: join or splice more than one cable. It must be a firm and secure union that the cables will not be separated, that when touched with bare hands there is no risk of contact with the cables or electrical contact, that it is durable and admit possible extensions in the
    20 installation, without worrying about buying larger items or having specialized tools for that function.
    The present invention patent aims, firstly, to reduce the cost of the assembly, and secondly to improve the constitution of the actual embossing, 25 presenting an embodiment for the fastening of the highly improved and at the same time simpler conductor cables. It also offers the possibility of reusing the same joint assembly if the splice of conductors in that installation is to be reduced or enlarged
    or union. It also allows the union without tools like
    screwdrivers, thus facilitating the assembly, disassembly or reuse in places that are little accessible or difficult to access.
    The system is provided with a first piece (male) through which the cables to be spliced, properly stripped, are inserted. The tips of these cables are twisted together and bent through this tube. Then, with the second piece (female), which acts as
    35 plug of the set, thanks to its conical shape, catches, holds and joins the electrical cables to be spliced. This second piece is introduced until a protruding pivot or notch fixes it to the first piece. With this system the cables are immobilized, although that immobilization can be undone and thus be able to reuse the system for another occasion, pulling the piece that acts as a plug, overcoming the resistance offered by the retention of the pivot or
    image3
    5 notch
    This system described in this patent, eliminates the difficulties or limitations that, sometimes, exist in a union or splicing of cables, at the time of proceeding: whether for space, lack of tools or having to have elements of various sizes or
    10 references to be able to make the splice, or expand the amount of cables to be spliced.
    This invention allows the connection from 2 to 7 conductors with the same size of splice connector. And to cover the different diameters of conductive cables that exist, only with 2 or 3 models or sizes, the needs are covered. For the
    15 that the models to be available for different installations or electrical connections are simplified. BACKGROUND OF THE INVENTION
    20 For the splicing of electric cables, different systems are known in the state of the art, depending on the number of wires to be spliced, different wire retention systems, method of contact between wires.
    For example, document ES 0162433 U deals with an improvement of the power strip
    25 splicing, or electrical connection strips, eliminating the conductive tubular element by a tongue, of electrically conductive tile-shaped material, its possible axial displacement being limited by an internal flange. But it maintains the use of screws to make the union.
    30 Document ES 0334416 A1 also deals with an improvement of the typical strip, replacing the tubular element with parts that improve the clamping of the conductors, by means of movable plates that tighten the fastening screws. Per this system also complicates the design and increases the amount of metal parts.
    35
    image4
    Document ES 0288894 U is a splicing system that, by means of a sheet or flexor tongue, allows quick connection by clamping the cables introduced by the openings of the skirt and imprisoned with the support piece. Although this system is of simple construction, without needing tools for its union and that allows the extension or
    5 variation in the number of conductors to be spliced, it still has metal parts, which can be permanently bent and cannot be reused in the future. It is also necessary to be able to introduce the cables correctly in the sheet, so that they are perfectly imprisoned, so using cables of different sections can cause them to come loose if they are on the same tab as a cable with a larger section.
    10 Document ES 2382291 T3 describes a connector and plug connection system. Nor does it use fastening screws, but rather tabs that press the cables one by one. The connector is of the male-female type and has pins for interlocking or fastening to another support element. But this system is still very complicated to
    15 manufacturing and only allows the connection of cables one by one, having to make bridges between the chambers to join cables of the same polarity.
    Document ES 2193312 T3 describes a simple system that, by means of a sheet of metal, imprisons the different conductors to be joined by means of flexible tabs, and
    20 allows the union of different conductors, even of different diameters, thanks to the flexion, to a greater or lesser extent, of the tabs. It is a simple manufacture, because it only consists of a mechanized sheet but has no protection with any insulating material. And it is also true that the pressure exerted on a cable of greater diameter is not the same as for one of smaller diameter and some conductor may come loose.
    25 Document ES 0216602 U describes a simpler joining system than the previous ones. Tubular shaped pieces (male-female) are inserted to make the union. It has some metallic element of easy manufacture and its assembly in uncomfortable places is feasible. The placement of the conductor cables does not need a tool
    30 insertion as they are inserted into the tubular connectors and the filaments are flexed to attach them to their own connector. But this system can only be used in wire-to-wire or wire-to-terminal connections, so it would not serve to join several conductors of the same polarity that we want to join.

    EXPLANATION OF THE INVENTION
    The invention consists of a connector for the connection of electrical cables, consisting of two parts, male-female, which, when fitted between them, allows the clamping of the cables to be spliced, prevents contact with the conductive cables.
    or metal parts and its reuse is possible by disassembling and assembling it on different occasions, and all this without using tools such as screwdrivers.
    The system is provided with a first piece where the cables are inserted
    10 splicing, properly peeled. The tips of these cables are folded through this tube. And then, with the second piece, which acts as a plug for the assembly, thanks to its conical shape, it catches, holds and joins the electrical cables to be spliced. This second piece is introduced until an outgoing pin fixes it to the first piece. With this system the cables are immobilized, although that immobilization can be undone and thus be able to reuse
    15 the system for another occasion. BRIEF DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help
    A better understanding of the features of the invention is accompanied as an integral part of said description, a set of drawings in which, with an illustrative and non-limiting nature, the following has been represented:
    Figure 1.- Shows a perspective view of the separate devices of the invention,
    25 unassembled. Figure 2.- Shows two perspective views of the devices of the invention mounted in their final position. Figure 3.- Shows a sectional view of the devices of the invention mounted in their final position.
    Figure 4.- Shows a view of the process of assembling cables with the devices of the invention. Figure 5.- Shows a view of the stripped cables for assembly. Figure 6.- Shows a view of the position that the cables should adopt in the assembly in the device of the invention.
    35 Figure 7.- Shows a view of the final assembly position of the devices of the
    image6
    invention. Figure 8.- Shows a sectional view of the final position of the assembly of the devices of the invention.
    5 Figure 1.- Shows a perspective view of the devices of the invention separated, unassembled, where all parts of the system can be identified. The female plug (1), has a flange (4) on the side that is fully covered to facilitate the thrust by joining the elements in the direction marked by the figure. It has a retention element (3) with a flange that will be attached to the edge of the male element (2). The element
    10 or male tube (2) has a conical shape on the outside to facilitate assembly.
    Figure 2.- Shows two perspective views of the devices of the invention mounted in their final position. By pushing the male element into the female, the retention pressure (5) will fix the elements. That retention is easily removable for your
    15 disassembly.
    Figure 3.- Shows a sectional view of the devices of the invention mounted in their final position. In this view you can see the conical shape of the two elements (male-female) to facilitate the pressure of the cables and thus their union.
    Figure 4.- Shows a view of the process of assembling cables with the devices of the invention. In the assembly process, any type of cable can be chosen. The cable wrap, at the ends to be spliced, will have to be "stripped" to allow them to be braided.
    25 Figure 5.-Shows a view of the stripped cables for assembly. It is also appreciated that once braided, they have to bend towards themselves. So the length to be stripped must be adequate to perform this step. This bending can also be done after inserting them into the male element, as shown in the
    30 next figure.
    Figure 6.- Shows a view of the position that the cables should adopt in the assembly in the device of the invention. When the cables to be spliced have been introduced, the end of the stranded wires must be bent inwards towards them
    35 cables, resting on the male element.
    image7
    Figure 7.- Shows a view of the final position of the assembly of the devices of the invention. Next we push the female element (plug), pushing with the flange (4) that helps to make pressure, until the retaining element (5) is encased in the other element.

    Figure 8.- Shows a sectional view of the final position of the assembly of the devices of the invention. In this view, it can be seen that when the female element (1) is introduced, the twisted cables (6) are trapped in the gap between the male element (2) and the female. Because the elements have a certain elasticity,
    10 can be adapted to make more pressure on the cables and retain them better. PREFERRED EMBODIMENT OF THE INVENTION
    The preferred form of manufacturing would be in plastic, by injection mold. As
    15 its conical shape will allow a good demoulding and easy manufacturing. The material to be used must be a plastic that allows a certain elasticity, because when holding the cables it can become deformed so that they are tightened between the walls of the male and female element. Besides, it must have elasticity so that the retaining element can function and be reused on different occasions.
    20 Also, the plastic material must have sufficient insulating properties to comply with the regulations for materials in electrical installations. The mass production with injection mold has the disadvantage that a mold has a considerable cost. That is why you have to make a mold with the maximum possible parts, so in each plastic injection of the machine, a large number can be made
    25 pieces, so the cost per piece will be negligible. Besides, with the great demand that the electricity market has on conductor splicing elements, the production will be massive. This will allow the amortization of the mold to be distributed among thousands of pieces, so it will not represent an increase in the cost price of each piece.
