JP4200449B2 - Connection block for lamp - Google Patents

Description

  The present invention relates to a connection block for a lamp, particularly an annular lamp, comprising an insulator, an electrical contact provided therein for connecting a conductor and a base contact pin of the lamp, and a connection block for a lamp coupled to the connection block. It has an associated rockable stop-curving piece, which at least partly surrounds the lamp with a holding edge in use.

  For prior art, see page 161 of Applicants' main catalog 2004/2007. Sockets and holders belong to the “G10q annular lamp socket” of the type series 26, 712 shown there, and a socket and possibly a plurality of holders are used for each annular lamp. The socket and the holder have a substantially C-shaped or U-shaped retaining curved piece that is swingably supported by the housing and bent from the wire. The stop-curved piece is swung over the lamp after the lamp cap is fitted into the connection block of the socket, thus holding the lamp in the socket or holder.

  If the socket is a problem here, the socket consists of a connection block with integrated electrical contacts and a housing that surrounds the connection block, which also supports the stop-curved piece in a swingable manner and attaches to the lamp part Therefore, an attachment mechanism is provided. Therefore, the connection block and the housing together form a socket.

  In practice, such sockets and possibly one or more lamp holders are usually fixedly attached to the lamp plate. However, so-called floating arrangements are possible, and the socket is removed and only the connection block (and possibly the holder) is used. The invention therefore does not relate first to the lamp socket, but only to the connection block or to the connection block as a component of the annular lamp socket.

  The mounting of the annular lamp in a suitable electric lamp is performed so that the lamp cap is connected to the connection block. Then the stop curve and possibly the stop curve of one or more holders are swung on the ramp. The lamp is removed in the reverse order.

  In floating connections characterized by the fact that the connecting block is not attached to the lamp, the retaining curved piece of the holder, if present, is coupled to the lamp to make an electrical connection to the connecting block. When removing the lamp, first the lamp cap and the connecting block are separated from each other, and then the additional holder retaining curved piece is reversed or vice versa.

  But what is important here is that the contact pins of the lamp are securely fitted to the contact of the connection block, so that a large pulling force is generated when removing the lamp, and after suddenly overcoming this pulling force, Control over the resulting movement is lost and the ramp strikes a nearby part. This can damage the lamp or destroy it at all.

  This is where the present invention begins. For the most part, the problem underlying the present invention is to make available a connecting block with an attached stop-curved piece, which makes it easier for the user to handle when removing the lamp from the connection block. That is.

  The present invention solves this problem by the features of claim 1, and is therefore characterized in that a release mechanism is attached to the retaining curved piece and the base of the lamp and the connection block are separated from each other by the opening movement of the retaining curved piece. .

  That is, the important core of the present invention is that the stop curved piece and the discharge mechanism are combined, and the lamp base is released from the connection block by releasing (open swinging) the stop curved piece. This prevents the lamp from destructively hitting the lamp part or other adjacent object as described above, and is therefore a significant improvement, particularly in lamps of the type having a floating lamp connection. At the same time, handling becomes significantly easier. This is because the stopper bending piece is operated with one hand, so that the other hand of the user can support and hold the lamp. Impulsive movements when removing the lamp from the connection block are reliably avoided by the present invention. As a result, the connection block can be prevented from being pulled out by pulling the conducting wire. Such pulling creates a risk of damage at the connection.

  Since the discharge mechanism is transmission coupled with the connection block, a new advantage also arises simultaneously when the lamp is inserted into the connection block. That is, in this case, the lamp cap now presses the release mechanism that forces the stop piece to move. As a result, when the lamp is inserted, the stop-curved piece automatically reaches the working position at the lamp. This is advantageous not only in terms of simple handling, but also in terms of mechanical and electrical safety of the entire device.

  In a specific configuration of the principle according to the invention, the stop-curved piece acts on the lamp without any further restraint in the intermediate position, but the base contact pin on the lamp side is not yet completely disengaged from the contact of the connection block. The stop-curved piece and the release mechanism are related. This allows, if desired, the lamp cap and the connecting block to remain mechanically loosely coupled without the lamp falling off. However, it is possible to pull out the lamp with almost no force by the hand without being obstructed by the stop curved piece. In particular in this connection, it is advantageous if the stop-curved piece is elastically configured and / or provided, so that the stop-curved piece can be deflected if it is still in the drawing range of the lamp. The elasticity of the stop-curved piece is advantageous for automatic tolerance compensation.

  In an advantageous embodiment, the stop bend piece and the release mechanism constitute an integral member. This member can be a relatively simple plastic injection molded part. However, it is within the scope of the present invention that other materials, such as plates or wires, are also within the scope of the present invention.

  In another configuration, the stop bend piece and the release mechanism each form one arm of a double arm lever, such as a swing lever. In this case, both arms of the swing lever can be in a substantially C-shaped or L-shaped correspondence with each other.

  With regard to the arrangement and / or correspondence of the retaining curved piece with respect to the connection block, according to an embodiment of the invention, the swing lever is provided with its swing axis on the connection block. In this connection, a swing lever can be provided in the receiving gap on the front side of the connection block and held by a cover fitted on the front side of the connection block. The cover can be inserted and locked in such a way that it can be released again depending on the connection block.

  The invention is best understood from the following description of the embodiments illustrated in the drawings.

  FIG. 1 shows a ceiling lamp 10 having an electric lamp housing 11 and two annular illumination means 12, 13 which are generally called annular lamps due to their annular shape. Two lamp sockets 14 are attached to the lamp housing 11 or the lamp plate according to the number of lamps 12 and 13. The lamp cap is labeled 15. Reference numeral 16 denotes an arcuate swingable fixture, after the lamps 12 and 13 have been inserted into the associated socket 14, the fixture is partially applied around the respective lamp tube to provide an annular lamp. 12 and 13 are held.

  The electric lamp 10 shown in FIG. 2 is different from the electric lamp shown in FIG. 1 in that the lamp socket 14 is not provided and only the connection block 17 is provided. Of the connection blocks 17, only the connection block associated with the inner annular lamp 12 is visible in FIG. The lamp cap 15 and the connection block 17 are separated from each other by a stop curved piece 18. More about that below.

  For the sake of overall understanding, what is to be mentioned is that the lamp block 14 of FIG. 1 which can also be configured as a so-called two-stage socket is integrated with a connection block 17 as used “uncovered” in the embodiment of FIG. That is. In the embodiment of FIG. 1, it is important to fix the lamp socket 14 to the lamp plate 11 having a conductor lead-in portion (not shown) from the back side of the lamp 10. On the other hand, in the lamp shown in FIG. 2, the conductor connection is “floating”. This is because the correspondence of the connection block 17 to a predetermined location on any one of the lamp plates 11 can be selected relatively freely.

  For both electric lamps described so far, the relevance with regard to the installation and removal of the annular lamps 12, 13 is at least impulsive when the lamp base 15 is withdrawn from the socket 14 or when the lamp base 15 and the connection block 17 are separated. This is a shocking movement that can cause the lamp 12 or 13 to strike a nearby object and destroy it.

  The present invention therefore provides a discharge system which makes it very easy to separate the lamp cap 15 from the connection block 17 (exposed according to FIG. 2 or integrated into the socket housing according to FIG. 1) by simple handling. provide.

  FIG. 3 shows the connection block 17, the retaining curved piece 18 and the cover 39. The connection block 17 is a molded body made of an insulating material, particularly plastic or ceramic. The connection block 17 includes a contact 20 for conductively connecting an electrical connection conductor (not shown) and a base contact pin 21 (see FIG. 11) of the lamp base 15. For this purpose, the contact 20 has a screwless connection terminal 22 at its rear conductor connection end and a bifurcated spring 23 for receiving the lamp cap contact pin 21 at its opposite end. The bifurcated spring 23 of the contact 20 can also be seen in FIG.

  The retaining curved piece 18 has two swinging support protrusions 24, and the connection block 17 has a support protrusion receiving portion 25 indicated by 25 in FIG. 3, and these receiving portions 25 open toward the front surface 38 of the connection block 17. Therefore, the support protrusion 24 of the retaining curved piece 18 can be clip-fitted to the receiving portion 25. This state is shown in FIG.

  As can be further seen from FIGS. 3 and 4, the connecting block 17 has a gap 26 that opens towards the front, which accepts a part of the stop-curved piece 18 and is defined by a swing support projection 24. A movement space for swinging around the movement axis S is provided.

  In order to hold the retaining curved piece 18 on the connection block 17, the cover 39 already described is provided. This cover 39 has locking hooks 27 arranged opposite to each other on the side, and these locking hooks 27 are engaged from the inside behind the edge 28 of the connection block 17 and there are locking openings there. 29. The cover 39 has four through openings 40 for the contact pins 21 according to the number and arrangement of the lamp contact pins 21 (FIG. 11).

  With respect to the swing axis S defined by the swing support protrusion 24, the stop curved piece 18 is configured as a double arm lever, and one arm 30 of the stop curved piece 18 is the original stop curved piece 18 as a holding side. The arm 31 is a release mechanism 32, and the function of this release mechanism will be described later.

  5 to 7 show the connection block 17 with the stop curve piece 18 integrated so as to be able to swing, in three characteristic positions.

  FIG. 5 shows the stop-curved piece 18 in an operating position in which the stop-curved piece 18 partially encloses the lamp or its lamp cap not shown here on the side farther from the connection block 17 from above. . In this first extreme position, the release mechanism 32 is in a non-operating position where it is retracted into the gap 26 of the connection block 17 and does not act.

  Another extreme position is shown in FIG. Here, the stop-curved piece is swung back to the place where the stop-curved piece 18 no longer contacts the lamp. On the other hand, the release mechanism 32 is in the position that protrudes most from the connection block 17, that is, the original release position.

  FIG. 6 shows the intermediate position. Here, the discharge mechanism 32 is ejected from the connection block 17 so that the discharge mechanism 32 pushes the lamp cap away from the connection block 17 until the contact pin of the lamp cap is still in contact with the contact of the connection block 17. On the other hand, the stop bending piece 18 is now swung open until the lamp can be separated from the connection block 17 by hand with almost no force.

  The state shown in the perspective view in FIGS. 5 to 7 is also shown in FIGS. 8 to 10, but for the detailed description of FIGS. 5 to 7, the individual descriptions of FIGS. 8 to 10 are unnecessary. However, it should be noted with reference to FIG. 9 that the stop-curved piece 18 is made of an elastic material or is elastically configured so that it is still not partially disturbed by the stop-curved piece 18 that is also behind the ramp 12. It is advantageous if the lamp cap 15 can be withdrawn from the connection block 17.

  Based on the above description, it can now clearly be seen that the release mechanism 32 is moved in the direction of the arrow 34 by opening the stop bend 18 in the direction of the arrow 33. Thereby, the lamp cap 15 is released from the connection block 17 at the same time until the lamp 12 is released and the position shown in FIG. 7 or 10 is reached. At this position, the lamp cap contact pin 21 is in contact with the contact 20 inside the connection block 17. The lamp 12 can be easily grasped and removed according to no force at all without any trouble.

  Conversely, when the base 15 of the lamp 12 is inserted into the connection block 17, starting from FIG. 7 or 10, the insertion of the lamp base 15 causes the discharge mechanism 32 to move in the direction of the arrow 35, so that the stop curved piece 18 is also inserted. At the same time, they are swung together in the direction of arrow 36. This means that the insertion of the lamp cap 15 into the connection block 17 brings the stop-curved piece 18 into a position (see FIGS. 5 and 8) that automatically locks the lamp 12 according to the force.

  The stop-curved piece 18 having two lever arms 30 and 31 and formed almost like a swinging lever consists of one piece as shown in the drawing, and in the illustrated embodiment, consists of a plastic injection molded part. It should be noted that the stop curved piece 18 has two stopper projections 37, and these stopper projections 37 significantly limit the opening swing of the stop curved piece 18 in the direction of the arrow 33.

  Finally, FIG. 12 shows that differently sized retaining bends 18 and 18 ′ can be used in the same connection block 17 to allow for lamps with different tube diameters and base diameters.

  Fig. 3 shows a perspective view of an electric lamp with two annular lamps, each electrically connected by a lamp socket.   FIG. 2 shows a perspective view of a lamp similar to the lamp of FIG. 1 with one connection block for each of two annular lamps.   FIG. 4 shows an exploded perspective view of a connection block according to the invention with a combined stop-curve-release mechanism and cover for the connection block.   FIG. 4 shows an exploded perspective view of different positions of a connection block that has been assembled and has a combined stop-curve-release mechanism.   FIG. 5 shows a perspective view of a connection block that has been assembled and has a stop-curve-release mechanism combination in one position.   FIG. 9 shows a perspective view of a completed connection block with a stop-curve-release mechanism combination in another position and assembled.   FIG. 6 shows a perspective view of a connection block that has been assembled with a stop-curve-release mechanism combination in yet another position.   FIG. 6 shows a perspective view of a connection block with a stop curved piece-release mechanism combination in a position corresponding to FIG.   FIG. 7 is a perspective view of a connection block having a stop curved piece-release mechanism combination in a position corresponding to FIG. 6.   FIG. 8 is a perspective view of a connection block having a stop curved piece-release mechanism combination in a position corresponding to FIG. 7.   Figure 2 shows a longitudinal section through a connection block with a fully discharged lamp.   The side view of the connection block which has a stop curved piece of a different structure is shown.
