- the base 100 is molded onto the pins 200, 300, 400 so that they each have an electrical connection part 201, 301, 401 projecting from the rear face 102 of the base 100 .
- the electrical plug shown more particularly in FIG. 2 comprises an electrical supply cable 500, the electrical wires 501, 502, 503 (here partially shown) are intended to be connected to the connection pins 200, 300, 400.
- the electrical plug comprises a U-shaped connecting element made of molded plastic, and intended to be fixed by complementarity d - shape on the rear face 102 of the base 100, straddling the electric power cable 500, pressing against it in order to secure it with said base 100.
- this connecting element 600 which will be called “jumper” in the following of text, has two vertical branches 620, 630 capable of being engaged respectively in two housings 130, 140 provided in the base 100 on either side of said bearing surface 110 so that the internal face 610 of said jumper 600 is supported on said portion of the power supply cable 500 in order to press it against the bearing surface 110.
- a row of three teeth 621, 622, 623, 631, 632, 633 is formed on the external face of each branch 620, 630 of the jumper 600 giving each branch 620, 630 a rack profile.
- each tooth 621, 622, 623, 631, 632, 633 of each branch 620, 630 of the U-shaped connecting element 600 extends obliquely with respect to the longitudinal direction of said branch, in the direction of the base 640 of said connecting element 600.
- the housings 130, 140 provided in the base 100 for mounting the connecting element each have a recess 131, 141 of shape complementary to that of the teeth of said branches. The mounting of the jumper 600 on the base 100 is then carried out by the cooperation of a tooth of each branch with the complementary recess in the corresponding housing of said base.
- the jumper 600 can be mounted, via its branches having a rack profile, depending on the shape and / or the size of the electric cable used, in three different positions more or less close to the base, corresponding to the attachment of a pair of teeth in said housings provided on either side of the bearing surface of the base. It will be noted that, according to variant embodiments of the jumper, not shown, it can be envisaged that a greater or lesser number of teeth per row to allow a greater or lesser number of positioning of the jumper on the base.
- FIG. 3 it can be seen that the internal face 610 of the jumper 600, intended to be applied against the electric supply cable 500, is provided with a rib 61 1.
- this rib 61 1 sinks slightly into the sheath 510 of said cable, locally causing plastic deformation of the sheath 510, which contributes to maintaining the cable on the base 100.
- the bearing surface 110 of the base 100 intended to receive the electric cable 500, is provided with an orifice 12 positioned opposite the zone of application of the rib 61 1 of the jumper 600 on the cable 500.
- the bearing surface 110 of the base on which said portion of electric power cable 500 is applied is shaped so as to frictionally retain said portion cable on said bearing surface 110 once the jumper 600 is mounted on the base, straddling the cable.
- said bearing surface 110 includes notches 111 transverse to the longitudinal direction of the cable 500, distributed around the orifice 112 and on which the sheath 510 of the cable 500 is applied.
- the tail of the base 100 has a flared portion in seat 120 behind the bearing surface 1 10, shaped to optionally receive the cable stressed in bending, during the use of the electrical plug.
- the bearing surface 110 comprises projecting outwards a row of three pins 110a.
