DESCRIPTION OF PREFERRED EMBODIMENTS

(8) In FIGS. 1 and 2, a first embodiment of the electrical contact for electrical cables according to the present invention is depicted.

(9) According to this embodiment, the electrical contact comprises a base (1) which is a substantially flat surface which serves to support the electrical contact.

(10) Said electrical contact also comprises two cutting and connection elements (2), although it could only comprises one cutting and connection element (2), which are placed substantially opposing each other as can be observed in the figures. If it is so desired, the interior edges of each pair of cutting and connection elements (2) can be slightly displaced with respect to each other, as is shown in FIGS. 1 and 2.

(11) Furthermore, according to the embodiment depicted in FIGS. 1 and 2, the electrical contact comprises two arms (11) which extend from the base (1) defining a U shape and a cutting and connection element (2) extends from each arm (11) towards the interior of the electrical contact, preferably from the part furthest from the base (1) of each arm (11) and in a substantially perpendicular manner.

(12) In order to facilitate the tilting movement of the arms (11) with respect to the base (1), these arms (11) preferably have an arched shape.

(13) Each cutting and connection element (2) defines an initial cutting edge (3) and a cutting and connection portion (4) such that the initial cutting edge (3) is arranged closer to the base than the cutting and connection portion (4), thereby providing a decreasing cutting force as has been previously described.

(14) The initial cutting edge (3) is the edge which first contacts the electrical cable (10) when the cutting of the cover of the cable is started, while the cutting and connection portion (4) is the portion where the electrical cable (10 is placed in the final connection position thereof as is shown in FIG. 2.

(15) As is evident, from the initial cutting edge (3) to the cutting and connection portion (4), there is a section along which the cutting of the cover of the electrical cable (10) is carried out and on the cutting and connection portion (4) the cover has been completely cut and the connection is created with the nucleus of the electrical cable (10).

(16) In this embodiment depicted in FIGS. 1 and 2, the movement of the electrical cable (10) from the initial cutting edge (3) to the cutting and connection portion (4) is rotation as has been depicted by means of the arrow of FIG. 1.

(17) Furthermore, according to this embodiment, the initial cutting edge (3) is associated with a mouth (5) for the placement of the electrical cable (10).

(18) Furthermore, the or each cutting and connection element (2) also comprises a knurling which improves the adherence of the cover of the electrical cable with respect to the electrical contact itself with the corresponding improvement in the action of the cutting of the cover due to the fact that it is adhered to the contact and helps to break the possible plastic fibers of the cover of the electrical cable (10) better.

(19) The cutting and connection elements (2) in this example define a plane which forms an acute angle with the base (1), that is to say, said cutting and connection elements (2) are oblique with respect to the base (1), providing a short tangent.

(20) In the FIGS. 3 and 4, a second embodiment of the electrical contact for electrical cables according to the present invention is depicted. For reasons of simplicity, in this second embodiment, the same reference numerals are used to indicate the same elements as in the previous embodiment.

(21) In this embodiment, the base (1) is a substantially flat surface, which serves as a joining for the cutting and connection elements (2) by way of the arms (11) thereof. The cutting and connection elements (2) also comprise an initial cutting edge (3) and a cutting and connection portion (4), the initial cutting edge (3) being closer to the base than the cutting and connection portion (4).

(22) Furthermore, in this embodiment, the electrical contact for the electrical cables also comprises two arms (11) which extend from the base (1) defining a U shape, a cutting and connection element (2) extending from each arm towards the interior of the electrical contact in a substantially perpendicular manner, although in this case from the end of the arm (11) furthest from the base.

(23) In this embodiment, the initial cutting edge (3) is also associated with a mouth (5) for the electrical cable (10). Also in this embodiment, the cutting of the cover of the electrical cable (10) is carried out, defining a rotational movement, as is indicated by means of the arrow of FIG. 3.

(24) In the FIGS. 5 and 6, a third embodiment of the electrical contact for electrical cables according to the present invention is depicted. For reasons of simplicity, in this third embodiment, the same reference numerals are used to indicate the same elements as in the previous embodiments.

(25) In this embodiment, the base (1) is an edge of the electrical contact and the principal different is that the electrical contact has a plate shape and the mouth (5) is a hole associated with the initial cutting edge (3). This hole is substantially circular and the diameter thereof is greater than the diameter of the electrical cable whose cover is desired to be cut.

(26) In this embodiment, the displacement of the electrical cable (10) from the initial cutting edge (3) to the cutting and connection portion (4) is translational.

(27) As in the previous embodiments, the distance of the initial cutting edge (3) to the base (1) is less than the distance of the cutting and connection portion (4) to the base (1).

(28) The functioning of the electrical contact of the present invention is the same in the three embodiments. Firstly, the electrical cable (10) should be placed facing the initial cutting edge (3), which is facilitated owing the mouth (5).

(29) Then the user displaces the electrical cable (10), initiating the cutting of the cover thereof on the initial cutting edge (3), a time at which the maximum force is applied.

(30) Once the cutting has been initiated, the electrical cable (10) continues being displaced towards the cutting and connection portion (4), but applying less force.

(31) Once placed in this cutting and connection position (4), the cover of the electrical cable (10) will be completely cut, the electrical connection being carried out.

(32) In spite of the fact that reference has been made to specific embodiments of the invention, it is evident to a person skilled in the art that the electrical contact for electrical cables described is capable of having numerous variations and modifications, and that all the details mentioned can be replaced for others which are technically equivalent without departing from the scope of protection defined by the attached claims.
