Definitions
- the object of the present invention is to further improve new, in particular touch-proof frames, especially with regard to installation size and ease of use. This is achieved through several measures.
- the main goal is to shorten the new version compared to the previous version, in order to at least partially compensate for the longer length of the energy-saving lamps compared to incandescent lamps.
- This is achieved according to the invention in that the connecting terminals are arranged in a ring outside the protective collar, which protects against contact of the lamp contacts when the lamp is inserted into the socket. This applies particularly to new, touch-proof frames.
- a device for attaching the socket e.g. on a wall, serving base plate is provided with a central feed for the power lines and channels or cavities for receiving the wires that lead to the ring-shaped terminals are available.
- the feeder can expediently be provided with a pipe thread in order to be able to screw the new version onto a pipe in the previously customary manner.
- connection terminals results in a substantial shortening, which should not, however, result in the use of standardized parts being lost. Therefore, according to the invention, it is proposed that appropriate threads should also be attached to the circumference of the frame in the new frame as in the previous frames.
- a particularly advantageous embodiment is not just a thread on the outer circumference of the socket. but also to provide a second thread on the protective collar.
- Figures 1 to 3 show an example of a socket according to the invention for lamps with a conventional Edison screw base.
- Fig. 1 shows a side view of the holder with the protective cover attached
- Fig. 2 shows a section through this holder
- Fig. 3 is a plan view with the protective cover removed.
- 4 to 8 show an example of a version according to the invention with a touch-proof contact system, corresponding approximately to the German patent application 197 23 029.6.
- FIG. 5 shows a section through such a holder and FIG. 6 shows a top view of this holder with the protective cover removed.
- 7 and 7a show the lamp base matching the socket in plan and elevation.
- Fig. 8 is a view of the socket with the protective cover attached.
- FIGS. 1 and 2 The main advantages of the inventive concept can be clearly seen in FIGS. 1 and 2.
- the height of the socket is practically less than half of the hitherto usual sockets in which the connection contacts are arranged axially behind the contact system.
- the possibility of providing an external thread (8) both on the protective collar (2) and on the outer circumference of the housing makes this new version compatible with almost all currently used versions.
- the thread (7) on the protective collar (2) corresponds to the internationally standardized dimensions of an Edison socket E14 and the external thread (8) can correspond to the dimensions of the Edison screw thread E27, which is also standardized worldwide.
- Luminaires with a socket according to the invention could be used compatible with both the accessories for the E14 and for the E27 system.
- the section Fig. 2 through this version shows the simple structure with a central screw thread (12) for lamps with E14 base.
- the ground contact (17) is designed as a simple stamped part and is designed in connection with the contact spring (19) as a screwless terminal.
- the power lines (13) can be plugged in through the holes (11), the adjacent hole (11) serving to push back the contact springs (19) with a pin in order to release the wire connection again.
- the centrally arranged contact system for receiving the lamp base has a thread (7) on the protective collar (2) in order to be able to attach accessories such as lampshades, among other things.
- accessories are available and standardized everywhere on the world market and the version shown as an example is compatible with the accessories for E14 sockets. 5
- an external thread (8) is provided on the largest diameter of the socket, which, for example, corresponds to the standards for an Edison screw thread E27. This makes this socket compatible with all accessories that are available for E27 sockets.
- the installation of the new sockets is extremely simple, as it basically only consists of three plastic components, namely the housing (1), the base plate (10) and a protective cover (9), which protects the connected, stripped wire leads (28) from contact protects, as shown in Fig. 6.
- the power lines can e.g. are inserted axially into the socket through holes (20), the holes (21) for fastening the socket, e.g. on a wall, do not protrude beyond the external thread (8). Both the fastening holes (21) and the holes (20) for the power lines are covered by the protective cover (9) after installation.
- FIGS. 4 to 8 The touch-proof version shown in FIGS. 4 to 8 is a further schematic example to explain the inventive concept.
- the sectional drawing in Fig. 4 shows how a lamp with a touch-proof lamp base (16) can be used.
- a plan and elevation of such a lamp base (16) is shown as an example in FIGS. 7 and 7a.
- it is a pin base with four base pins (22) which are contained in a base extension (26).
- Locking profiles (25) on the base attachment secure the lamp after insertion in cooperation with resilient catches (24), as shown in Fig. 4.
- the lamp base (16) with its locking profile (25) is shown in Fig. 4 with dashed lines.
- the lamp base (16) lies on the protective collar (2) after the lamp has been inserted. In order to 6 The penetration of dust or even insects often observed in previous versions is reliably avoided.
- FIG. 5 shows a section through the contact system.
- the resilient contacts (4) rest on the base pins (22) which protrude through the holes (23).
- the live, springy contacts (4) are located behind the holes (23) and are safe to touch even when changing the lamp.
- connection terminals (3) are shown as screwless terminals, for example, the contact springs (19) also reliably clamping the bare ends of the insulated cable wires (28) which are inserted through the holes (11).
- Fig. 4 is shown schematically how the power line (13) with the insulated line wires (28) is used centrally in the base plate (10), in this example the central entry is designed as a pipe thread (5), which is an assembly of Socket on a tube end of the appropriate diameter is permitted, as is common in the lighting industry worldwide.
- an assembly opening (29) can be provided, which is accessible from the outside, which facilitates the insertion of the insulated cable cores (28) into the channels (6).
- the protective cover (9) is placed on the holder according to FIG. 6 and fastened, for example, with two cover screws (14).
- the associated threads (15) are provided in the housing (1).
- a snap connection which can only be released with a tool, is also possible in this case in order to make the assembly of the protective cover (9) even easier.
- the same also applies to the assembly of the base plate (10) with the housing (1).
- the cutouts (27) may serve to position the protective cover (9), which can also have corresponding projections (30), as shown in FIG. 1. 7
- the two versions according to the invention shown schematically as an example cannot of course exhaustively describe the inventive idea. In contrast to these examples, all parts can be designed differently. This applies to the contacts as well as to the locking system and the connection terminals. The examples shown serve only for a better understanding of the invention.
