Finally, in the configuration for the market Turkish, type "UPS", represented in figure 8, the base will be, as explained above, provided with contacts (3) for the correct fixing of the pins of the plug, and the grounding contact, consisting of an identical contact to the of the "schuko" configuration, formed by the arms (16) extended by (17) and plate (18), completing with a spike cylindrical vertical (12), identical to that of the base type "French", leaving all this set of grounding fixed in the corresponding place (4) of the base body (1), by means of rivet (14).

The contact plates (13) and (18) have lateral fins (15) that are introduced under the lugs (4a) that serve as a guide to avoid that, in the assembly, the force exerted upwards by the electrical conductors cause the bent of said contact plate.

Between the fins (15) are located, by below, longitudinal grooves (15a) as seen in the Figure 12, which will be used for correct positioning and tightening of the electrical conductors in the contact zone for the embordered

It should also be noted that in the last three "French", "schuko" and "UPS" settings, are place a screw (10) together with the locknut (11) on the motherboard contact (13) and (18), to get a flange correct electrical conductor that will be placed there.

The mechanism object of the present patent of invention is complemented by a fixing frame (6), which It is designed for use in any of the four configurations described above, so identical to the base body (1) that will be mounted with the frame (6) will be used, without any variation, for anyone of these configurations.

Said fixing frame (6) has, on its face top, various holes (19), typical of these racks, which they will allow their proper support in the place where the mechanism will be recessed for later operation.

By its inferior face, the frame (6), has a Octagonal perimeter vertical tab (20), located just next to the entire perimeter of its central opening (6a). In the Figure 20 the indicated can be clearly seen.

The different elements that such a frame has (6) and which will be described below, allow mounting and fixing the properly on the base body (1), first of all in the "Bipolar" and "French" settings, while the assembly for "schuko" and "UPS" configurations it will require giving the repeated frame (6) a simple 180 ° turn. In these cases the separation distance between the frame (6) and the body (1) will vary approximately 3 mm.

Next to its four vertices of the frame (6), there are rectangular openings (21), coinciding in the corresponding sides of the octagonal vertical flange (20).

In these four specific places, the tab (20) has a stepped profile, with a step area (22) of greater height, and another contiguous area (23) of smaller height. These steps are arranged in opposite position two to two so that when the frame (6) is mounted on the base body (1), they will stop on side benches (27) that have the turrets (5), the frame being more or less separated from the base (1) according to butt the steps (22), of greater height, or the steps (23), of smaller height.

Said rectangular openings (21) allow the frame (6) is placed on the base body (1) for its correct assembly, entering through these openings (21) by the top of the turrets (5), this operation that effect easily, thanks to the slight flexion of their own turrets, given the flexibility of the material of the same.
