According to the invention, a lamp socket consists of an insulating housing with a support part for a tubular lamp and means for fastening the fit on a carrier plate and contact springs. inside the socket housing and the fit is thereby characterizedj that the insulating housing is one of a Piece of existing plastic molding is that an im essentially rectangular body part with separate cavities that extend parallel to each other from a flat end surface of the body part to receive the contact springs, two elastic Arms made from one piece - from two opposite sides of the body portion and beyond the end surface extend and deviate slightly from the axis of the cavities and with outward extensions, while the section carrying the tubular lamp is perpendicular to the cavities and the elastic arms extending from one of the remaining sides of the body portion, the inner end thereof through corresponding ones Openings communicating with each of the cavities.

For further features and advantages of the invention, see from the following description of an embodiment shown in the accompanying schematic drawing. .

A socket housing 1 is made in one piece from resilient plastic and has a tube support section 2, a body section 3 and two flexible fastening arms 4. The tube support section 2 is of a tubular shape and adapts to that of one end of a fluorescent tube 5. A wall 6 separates the tube support section 2 from the body section J and holes 7 extend through the wall 6 for the passage of the contact pins 8 of the fluorescent tube 5.

The body portion 3 has two cavities 9 which

arranged essentially perpendicular to section 2 are and each cavity is in communication with the interior of the pipe support section 2 via corresponding Holes 7 · Protruding parts Io extend the walls of each cavity 9, and an opening 11 lies in the bottom of each cavity 9 in alignment with the outstanding parts Io.

The two holding arms K extend out at a slight angle from opposite sides of the body section 3. Each arm has a transverse slot 14 near its outer free end which forms a protruding part 15.

The contact springs 16 are designed so that they are in engage corresponding cavities 9 and have a wire clamping part 17 and a contact portion 18. The contact section 18 is U-shaped, the legs being slightly inclined towards one another. Of the The base part of the contact section 18 is essentially flat and has a hole 2o. Each leg of the U-shaped Contact section 18 has a part which is sheared off in an outward direction and which forms an attachment part 21.

During assembly, the contact springs 16 are

A contact part 16 can be removed from its cavity by inserting a forked one (not shown) Tool in the opening 11 to the extension parts 21 from the protruding parts Io of the housing to free. When two contact springs are 16 in. the caves 9 are arranged, two versions 1 are on two ends of the fluorescent tube 5 arranged, wherein the tube carrying sections 2 around the ends of the tube ■ give and the contact pins 8 through the holes 7 extend into engagement with corresponding contact springs 16. The fastening arms 4 of each socket 1 are then pressed towards each other and in accordingly shaped plate openings introduced. The attachment |

arms Λ are then released to spring back to their normal position and the slots I ^ engage the edges of the openings in the plate ...

If desired, an additional mounting hole can be added 15 in a curved extension 12 of the body portion 3 of the insulating housing to allow an additional fastening screw to pass through. · ■ -, - "· - ■ - 909842/0742
