Plug-in light

The invention relates to a plug-in lamp with a socket for receiving a light bulb, one that surrounds the socket Housing and a reflector screen, furthermore with contact pins arranged at the rear end of the housing, with in the socket arranged socket contacts and conductors.

Such plug-in lights are plugged into wall sockets as simple, yet effective lighting fixtures. she are used on a large scale where a fixed installation of lights is too expensive and where the position of wall sockets enables such wall lights to be attached.

In the known wall lights of this type, the contacts are pins at the rear end into a standard Schuko · ^ Plug inserted, which is connected to the housing. The contact pins are wired to a commercially available one Ceramic socket connected. A switch mounted in the housing is also included in the wiring.

The invention is based on the object of a plug-in lamp of the kind assumed to be known from simple prefabricated units, whereby wiring is not required and the assembly, at least largely dispensing with separate ones

Connecting elements such as screws, rivets or the like should be possible.

According to the invention, this object is achieved by., that the contact pins sit at the rear end of a circuit board carrying the current conductors, which is on its front side Carrying socket contacts and which is encompassed at its front end by the socket divided in the longitudinal direction, which is locked with the housing.

Preferred embodiments of the invention are described in the subclaims.

The plug-in lamp according to the invention consists of a few, simply structured individual parts that are simply put together for assembly. The assembly is under extensive To do without tools by unskilled workers. It is sufficient to simply slide the different components, which are locked together via corresponding molded connecting means and in their assembly position be determined.

The version of the subject of the application differs from the usual versions, since they only have the mechanical receptacle for the light bulb forms, but does not itself carry the socket contacts., The socket contacts are instead molded onto the circuit board. This separation enables a particularly simple production the socket according to the application made of heat-resistant plastic, for example from polybiatylene terephthalate. The case and the reflector screen are made from the usual plastics, for example from ABS or polycarbonate

The following is a preferred embodiment of the invention described in detail with reference to the drawing. It

The circuit board 3 is connected to the socket 11 by first pushing the recesses 25 of the circuit board 3 onto the pins 24 of the socket 11. Then the two halves of the frame, which are connected by a film hinge 28, are folded together and the pegs 24 passing through the recesses 25 engage in the peg holes 27. The unit consisting of socket 11 and printed circuit board 3 thus preassembled is pushed into longitudinal guide grooves 12 and 13 from end face 21. It is inserted so deep that the locking lugs 1 ^! 4 and 15 of the version: jn associated recesses 16 and 17 of the housing 2 are resiliently engaged. In an embodiment with a reflector screen 1, as shown, the circuit board and the socket must first be inserted through the through opening 20 of the reflector screen before inserting the unit consisting of circuit board 3 and socket 11 and only then can the described insertion of the circuit board until it latches take place. The reflector screen is then immovable in the axial direction, but is mounted rotatably about the longitudinal axis 21 of the mount 11. The reflector screen 1 is held between the front edge 22 of the housing 2 and the collar 23.
