Description

File number: 5148-004 Revision: as filed Date: 26-03-2008 Title of the Invention [0001] Neon Connector Cross-Reference to Related Applications [0002] There are no cross-related applications.
Field of the Invention [0003] The present invention relates generally to means to provide an insulated connection between the wires of the power supply cable and a neon tube electrode required in the installation of neon tubes and more particularly to a neon connector which is adaptable to a plurality of power supply cable sizes.
Background of the Invention [0004] Neon signs comprise glass tubes which are bent into various configurations and have electrodes sealed into their opposite ends. The color of the light which is emitted when a high electric potential is applied across the electrodes depends on the particular inert gas with which the tube is filled. Argon, krypton and neon are the most commonly used gases, but for the sake of brevity, all light emitting gas filled tubes to which the new connector is applicable will be called 'neon' tubes herein.
[0005] Wires typically extend from the electrodes through the pinched-off ends of the glass tube and insulated wires in a cable which extend from a high voltage power supply are directly connected to the electrode wires and the connections are wrapped with insulating tape or a heat-shrinkable insulating tube. Fine gauge supply wire is used because the current through a neon tube is relatively small, in the milliampere range, but the power supplies have high output voltage. Voltages may range from about 6,000 volts to 15,000 volts which, needless to say, produces trauma when voltages at that level are File number: 5148-004 Revision: as filed Date: 26-03-2008 accidentally applied to the human body. The lead wires from the power supply to the neon tube are usually covered with a very flexible insulating material such as rubber.
[0006] A neon tube electrode, especially those used in modern advertising signs, often must be mounted outdoors where it is subject to a variety of adverse weather conditions.
The electrical connection between each tube electrode and its associated power cable such as GTO cable, requires protection from moisture and other adverse components of the environment. If these connections are not properly covered, the useful life of the sign will decrease and hazardous shorts can occur which create a safety hazard at the site of such signage.
[0007] The voltage necessary to start neon tubes changes depending of the charge needed for a particular neon sign. The cable sizes are thus variables and it is usually necessary to have a plurality of connector parts to adapt to the multiple cable sizes that are used.
[0008] Thus a need still exists for a neon connector which is simple to install and which is adaptable to a plurality of cable sizes. It is toward this need that the present disclosure is directed.

Objects of the Invention [0009] Accordingly, it is the principal object of the present invention to provide an insulated connection between a power supply cable and a neon tube electrode.
[0010] It is another object of the present invention to provide a neon connector which is adaptable for different cable sizes.
[0011] Another object of the present invention is to provide a neon connector which is simple to install and which has the versatility for use with straight on or double back installations.

File number: 5148-004 Revision: as filed Date: 26-03-2008 [0012] Other and further objects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
Summary of the Invention [0013] The aforesaid and other objectives of the present invention are realized by generally providing a neon connector providing an insulated connection between the neon electrode of a neon tube and the wires of a power supply cable, the neon connector being adaptable to a plurality of cable sizes, the neon connector comprising a cable sleeving adapter portion having a generally cylindrical shape, the cable sleeving adapter portion comprising a cylindrical cavity, and wherein the cylindrical cavity has a plurality of longitudinally extending sections, each section having a predetermined diameter, and a housing portion, the housing portion comprising at least one opening to receive the electrode .
[0014] The present invention, in another embodiment, provides a neon connector providing an insulated connection between the neon electrode of a neon tube and the wires of a power supply cable having a predetermined diameter, the neon connector comprising a cable sleeving adapter element having a generally cylindrical shape, the cable sleeving adapter element comprising a cylindrical cavity having a first end having a first diameter and a second end having a second diameter corresponding to the predetermined diameter, and a housing element, the housing element comprising at least one opening to receive the electrode of the neon tube.
[0015] The neon connector of the present invention is adaptable to the straight on type of installation as well to the double back type of installation. For a straight on type of installation, the housing portion is a sleeve portion having a generally cylindrical shape and comprising a first end and a second end. For the double back type of installation, the File number: 5148-004 Revision: as filed Date: 26-03-2008 housing portion is an end cap portion, the cap comprising a first and a second cylindrical cavities.
[0016] In a preferred embodiment, to install the neon connector, the cable sleeving adapter portion is cut prior to the installation at predetermined position, as necessary to accommodate the actual size of the cable to be used. The cable sleeving adapter portion is cut at predetermined positions so that is it adapted to receive a particular cable size. The predetermined positions may be indicated by different means, such as for example, a parting line or an arrow.
[0017] In another embodiment, the sleeving adapter element or portion is distinct from the housing portion or element and is available in a plurality of configuration, each designed to be used with a given cable size.
[0018] For a straight on type of installation, the housing portion is a sleeve portion. The cable sleeving adapter portion is slid on the cable by inserting the cable into the first extremity of the cable sleeving adapter portion. The sleeve portion is then slid on the cable by inserting the cable into its first extremity. The wires of the power supply cable are connected to the electrode of the neon tube, and the cable sleeving adapter portion is then inserted into the sleeve portion through its first extremity and the electrode of the neon tube is inserted into the sleeve portion through its second extremity.
[0019] For a double back type of installation, thus with an end cap portion, the cable sleeving adapter portion is slid on the cable as mentioned previously, through the first extremity. The connection is made between the wires of the power supply cable and the electrode of the neon tube. The neon electrode is then inserted into the first cavity of the end cap portion and the cable sleeving adapter portion into the second cavity of the end cap portion.
[0020] The cable sleeving adapter portion is preferably designed so that a force is necessary to remove the power supply cable. This force is typically of three pounds but it File numbec 5148-004 Revision: as filed Date: 26-03-2008 may vary. Each portion of the cable sleeving adapter having a particular diameter has a minimal length which is chosen so it is possible to have the desired friction to obtain the retention force for each diameter.
[0021] The cable sleeving adapter portion and the housing portion are made of a material which is prefererably slightly resilient and which is preferably also flame retardant, such as, for example, PyroleneTm.
[0022] The features of the present invention which are believed to be novel are set forth with particularity in the appended claims.

Detailed Description of the Preferred Embodiment [0035] A novel neon connector will be described hereinafter. Although the invention is described in terms of specific illustrative embodiment(s), it is to be understood that the embodiment(s) described herein are by way of example only and that the scope of the invention is not intended to be limited thereby.
[0036] Figures 1, 2 and 3a illustrate the cable sleeving adapter portion 100.
Figure 3b show a second embodiment of the cable sleeving adapter portion. The cable sleeving File number: 5148-004 Revision: as filed Date: 26-03-2008 adapter portion 100 has a generally cylindrical shape. The cable sleeving adapter portion of Figure 3a comprises two cylindrical cavities, a first cylindrical cavity 110 and a second cylindrical cavity 115 each one having different diameters to accommodate two sizes of cable (not shown). The parting line 120 indicates where the cable sleeving adapter portion 100 has to be cut when a cable having a size corresponding to the second cylindrical cavity 115 is used. There is preferably a flat section 130 on the cable sleeving adapter portion 100. A portion of the second cylindrical cavity 115, the longer portion, is slightly tapered to facilitate the insertion or the removal of the cable.
[0037] The second embodiment of Figure 3b comprises four cylindrical cavities 160, 162, 164 and 166. Preferably, a portion of the fourth cylindrical 166, the longer portion, is slightly tapered.
[0038] Figures 4a and 4b show the connection between a neon tube 430 and a cable 405.
The cable sleeving adapter portion 410 is cut if necessary to correspond to the cable size to be used. The cable sleeving adapter portion 410 is slid over the cable 405 followed by the housing portion 415. The wires 420 are then connected to the electrode 425 of the neon tube 430. When this connection is made, the cable sleeving adapter portion 410 is inserted into the first end 442 of the housing portion 415 and the neon 430 is inserted into the second end 444 of the housing portion 415.
[0039] Figures Sa to 5d show the neon connector, comprising a housing portion 140 and the cable sleeving adapter portion 100, as used with four sizes of cable (the wires of the electrode and of the cable are not shown in some of the figures). The housing portion shown in these figures is of the straight on type, also called a sleeve portion. The neon electrode 225 of the neon tube 220 is inserted into the sleeve portion 140 through the second end 144 and the cable sleeving adapter portion through the first end 142. In Figure 5a, the cable sleeving adapter portion 100 is used as is, the cable 210 corresponding to the first diameter 230. In Figure 5b, the cable sleeving adapter portion 100 is cut so that a cable 212 corresponding to diameter of the second cylindrical cavity 232 may be used.
Similarly, in Figures 5c and 5d, the cable sleeving adapter portion 100 is cut to File number: 5148-004 Revision: as filed Date: 26-03-2008 accommodate cable 214 and 216 having diameters corresponding to the third cylindrical cavity 234 and the fourth cylindrical cavity 236 respectively.
[0040] Similarly, in Figures 6a to 6d, a double back type of housing portion is shown, also referred as an end cap portion. The end cap portion 310 comprises a first cylindrical cavity 350 and a second cylindrical cavity 355 that are adapted to receive the neon electrode 335 of the neon tube 320 and the cable sleeving adapter portion 100 respectively. It is possible to see the utility of the flat section 130 in these picture; indeed, it allows the cable sleeving adapter portion 100 to be closer to the neon tube 320. The neon electrode 335 of the neon tube 320 is inserted into the electrode cavity 350 of the end cap portion 310 and the cable sleeving adapter portion into the cavity 355. In Figure 6a, the cable sleeving adapter portion 100 is used as is, the cable 210 corresponding to the first cylindrical cavity 230. In Figure 6b, the cable sleeving adapter portion 100 is cut so that a cable 212 corresponding to the second cylindrical cavity 232 may be used.
Similarly, in Figures 6c and 6d, the cable sleeving adapter portion 100 is cut to accommodate cable 214 and 216 having diameters corresponding to the third cylindrical cavity 234 and the fourth cylindrical cavity 236 respectively.
[0041] Figures 7 and 8 show the connection between a neon tube 730 and a cable wherein the cable sleeving adapter portion and the housing portion are unitary. The cable sleeving adapter portion 710 is cut if necessary corresponding to the cable size to be used.
The cable sleeving adapter portion 710 is slid over the cable 705 until the cable exits at the opposite end of the housing portion so that the wires of the cable are accessible. The wires 720 are then connected to the electrode 725 of the neon tube 730. When this connection is made, the neon 730 is inserted into the housing portion 715.
[0042] In Figure 9, a double back type of housing portion and a cable sleeving adapter portion that are unitary. The end cap portion 910 comprises a first cylindrical cavity 950 and a second cylindrical cavity 955 that are adapted to receive the neon electrode 935 of the neon tube 920. The cable sleeving adapter portion 900 is connected to the housing portion 910. The cable 920 is inserted into the cable sleeving adapter portion 900 and the File number: 5148-004 Revision: as filed Date: 26-03-2008 wires of the cable 920 are pull out of the cavity 950 to be connected to the neon electrode 935. The neon electrode 935 of the neon tube 920 is then inserted into the electrode cavity 950 of the end cap portion 910.
[0043] While illustrative and presently preferred embodiment(s) of the invention have been described in detail hereinabove, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
