This earthing contact socket, which forms a special component, has for the purpose of preservation in plugs of the above-mentioned known type the required elasticity a relatively great length «It is mechanical by a connecting means and electrically connected to said bracket.

The innovation creates the possibility of using the earthing contact socket shorter and easier to train.

According to a first feature of the innovation are the at least substantially U-shaped metal bracket, the legs of which facing away from the free end face of the insulating body and the

single
Earthing contact socket formed from a / sheet metal piece. In addition to saving material, this also simplifies production.

Be in accordance with a further feature of the innovation, the ground contact sleeve can in this case on which the legs of the yoke connecting l'eil by bending and partial ^ urückbiegen of this part _s connected in parallel extending side strips formed _s wherein at the location, this page strip weighed with the linking x'eil of the bracket are related, the insertion opening is arranged for a grounding pin.

The new features are described in detail below using the illustrations explained, which illustrate an embodiment of a Üteckers with the features of the innovation.

with a jury contact box formed on it «,

From Figures 3 to 6 inclusive, manufacturing phases of the U-shaped. Bracket with - ^ earthing contact socket can be seen.

The in S ¹ Ig. 1 connector shown in longitudinal section consists of an insulating body 1 made of rubber or other elastic insulating material 5 which can form a whole with the common 'sheath of the insulated conductor 2.

The two pins 3 of this connector are carried by a rigid body 4 made of insulating plastic material, which has a (in Fig. 1 and 2 to the right) end hervorra _& lug 5, which is a support of the central part 6 of a U-shaped ^ etallbugels whose outwardly exposed legs 7 form the two ürdungslamellen, over almost its entire length forms »

The body 4 with a flag 5 is in the usual way in the The insulating material of the insulating body 1 is embedded.

As can be seen from Figo 2, in the smock part 6 of the TJ-shaped Clamp the insertion opening 8 for yourself not

earth contact pin shown "

below is based on Figures 3 up to and including the way in which the U-shaped bracket and the ground contact socket are made from a piece of sheet metal, described in detail.

Fig. 3 shows the flat starting piece made of sheet metal, in

which already said insertion opening 8 at the point educated

is, on which two parallel side strips 10 are connected to the strip 9 to form the U-shaped bracket, which to the two interacting with each other

en,
'i'eil / of the earthing contact socket must be bent.

The following step of the manufacturing process is illustrated in FIGS. The side strips 10 are doubly curved and v / iron on a longitudinal profile, aas clearly can be seen from Figure 5, while the ends of the strip in Figure 5 can also be seen from the last-mentioned figure. V / eise are bent.

The comparison of FIGS. 3, 4 and 5 with FIG. 2 results without further ado that aie 'parts of the otreifen 9 to both Sides of the insertion opening 8 have a very different length

to record. In FIGS. 5, 4 and 5, the length is therefore of the lower part of the strip 9 drawn broken off.

From the part of the strip 9 which later becomes the middle part 6 of the UiE-shaped bracket is still a bent lip 11 punched out, which is used to attach to the U-shaped B-pgel to jei'eatigen the - ^ rdungsleiter. This is usually done by soldering »

A comparison of FIGS. 4 and 6 shows that the Formation of the U-shaped bracket uit ^ rdungskontaktbüchse thereby is completed, ate the two end parts of the "strip 9 bent at right angles to form the earthing lamellae 7 and also the bent back strips 10 'are bent at right angles so that their

and

and

End regions approach one another, those shown in FIG. 6 approach Education results.

From the cross-section according to Figure 1 it can be seen that in the rigid body 4 below the so _ö e-formed and close to the free (end face of the insulating body 1 lying ir-

the connection contact bushing is also formed a cavity 12 which is connected to picks up parts of a grounding contact pin protruding through the grounding contact socket.

Of course, are changes possible compared to the versions of the new connector described above and shown in the figures _? without deviating from the basic idea of the innovation "
