The development according to claim 2 has the advantage that the largest possible area for recording the weight of the lamp is available and that the support connection by clamping effect is secured against unintentional I..oren. The measures proposed in claim 3 provide additional security for the plug head the connection position.

The development of the invention according to claim 4 ensures complete strain relief of the connection _: pins within the plug head.

an end plateS covered. In the end plate, there are also two diametrically opposite arc cutouts 6 which open up access to the connection space 7 within the cylinder wall 3. Within this connection space 7, there are two contact springs 8 cut out onto the arched cutouts 6, which are held with connection lugs 9 on connection pieces 10. The contact springs 8 each have contact shells 11 pressed in in the area of the intended contact position, as can be seen in particular in FIG The connection pieces 10 are firmly molded, for example injected, into the face plate S. The connection pieces 10 serve to connect a line core 12 of a connection line 13. The drawing shows a screw connection piece 10. _Of course, a crimp connection piece or a screwless connecting piece provide. it is important that the contact springs 8 are aligned in their course to the terminal end of the Bogenausschnitte6, see FIG.
