    专利说明:
    POWER TRACK The invention relates to a power track, especially a power track made of metal, having an essentially U-shaped cross-section and having parallel side walls that laterally delimit a retaining channel and carry respective dielectric support rails in turn each carrying a respective plurality of uninsulated, bare electrical conductors that are insulated from one another, parallel to one another in the rail longitudinal direction, opposite one another, and exposed in the retaining channel, three of the conductors being used as phase conductors and one being used as neutral conductor, a ground conductor that is likewise exposed in the retaining channel also preferably being provided on a base of the power track. Such a power track may be found for instance in FIG. 3 of DE OS 22 50 738. Proceeding from this prior art, the underlying object of the invention is to provide a power track of this type that, in addition to three-phase rotary current operation also permits the additional connection of other consumers or of signal transmissions. To attain this object it is proposed that between each conductor pair on a respective support rail are a fifth and a sixth bare conductor that are insulated from the conductors of the respective conductor pair, the fifth and sixth conductors being opposite one another and being exposed in the retaining channel, the fifth and sixth conductors being used as control conductors for an electrical or electronic control or as additional power conductors for other electrical consumers. This arrangement makes it possible not only for the three phase conductors and the neutral conductor to be used as connectors for the phases during three-phase rotary current operation, but also for other consumers, for instance emergency light, safety illumination, other low voltage consumers or even alternating current consumers, signal transmission, and the like to be connected using the fifth and sixth conductors. In a manner known per se, support formations for an adapter inserted into the power track are formed on the outer edges of the side walls remote from the base of the power track, one of these support formations preferably holding a bare ground conductor that is exposed in the retaining channel. -1- The arrangement of another ground conductor in one of these support formations is an option that is provided depending on the design of the adapter and that is compatible with the power track. Normally a ground conductor is eccentrically provided on the base of the power track, as is known from the prior art cited in the foregoing. Additionally or alternatively, a ground conductor may be arranged in the support formation of the power track. In order to fashion an arrangement in which creep voltages flowing between the phase conductors the neutral conductor, and the fifth and sixth conductors are suppressed, each dielectric support rail has seat grooves delimited by a first lateral bar, a center bar, and a second lateral bar, for receiving a phase conductor and/or neutral conductor, the center bar being forked in a U shape at its outer edge remote from the respective side wall of the power track to which the support rail is fixed, and the fifth or sixth conductors are into the respective forks so as to be positioned at the base of the respective fork while the fork legs project sufficiently beyond the fifth or sixth conductor to prevent creep voltages to the phase conductors or the neutral conductor. This embodiment ensures that creep voltages can be prevented. Moreover, to improve this behavior the center bar can be of reduced thickness in the area between its base and the insulating clips holding the phase conductors or the neutral conductor for forming an extended creep-voltage flow path. In addition, in a manner known per se an air gap is formed between the dielectric support rail and the side wall holding it, at least at the phase conductors or the neutral conductor. Preferably also the support rails each hold the two phase conductors or one phase conductor and the neutral conductor in a plane lying parallel to the side wall of the power track and the fifth conductor and the sixth conductor each lie in a plane that is offset toward the interior of the power track with respect to this plane. Also preferably the outer edges of the first and second lateral bars and the ends of the fork legs of the center bar lie in a plane that extends parallel to the side walls of the power track. Moreover, the phase conductors, the neutral conductor, and the fifth and sixth conductors are protected from manual contact by being recessed in the respective support rails. One special characteristic the end of the power track is fitted with a connector, input, or end piece formed as a coupling that is made of insulating material and has a connecting conductor that is in contact with the phase conductors, the neutral conductor, the fifth and sixth conductors, and -2with a ground contact, parts of the coupling made of insulating material engaging in cavities of the power track that are formed between the support rail and the side walls of the power track and in a space that is formed between a support bar for the fifth or sixth conductor and the insulating bar adjacent thereto that holds the area of each phase conductor or of the neutral conductor that is adjacent the support bar. The inventively power track can both be connected to a three-phase current and also permit connection to signal transmission and the like. In one conventionally accepted design of the power track, for instance, 3 x 16 amperes can be connected via the phase conductors for three-phase rotary current operation. In addition, a load with 10 amperes for other conductors may be accommodated using the fifth and sixth conductors, or alternatively they may be used for signal transmission or other installations. The air gap and creep paths are retained. One embodiment of a power track is shown in the only figure where a power track is shown in an end-face view. A power track 1 made of metal is provided that has an essentially U-shaped cross section. Parallel side walls of the power track flank a retaining channel 2 that is closed delimited at the top side by a base of the power track 1. Support rails 3 made of insulating material are arranged on the side walls of the power track 1 and fixed by deformable bars 4. These support rails 3 each receive a plurality of uninsulated bare electrical conductors 5, 6, 7, 8 that are insulated from one another, extend parallel to one another in the rail longitudinal direction, are opposite one another, and are exposed in the retaining channel 2. Of these conductors, three are used as phase conductors, for instance the conductors 5, 6, 7. One of these conductors is used as a neutral conductor, for instance the conductor 8. In addition, formed or provided in the illustrated embodiment on the base of the power track 1 is a ground conductor 9 that is also exposed in the retaining channel 2. Arranged between each conductor pair 5, 6 or 7, 8 that is held in a support rail 3, insulated from the conductors 5, 6 or 7, 8 of the conductor pair, is a fifth conductor 10 and a sixth conductor 11. The fifth and sixth conductors 10, 11 are disposed opposite one another. Again, both conductors are exposed in the retaining channel 2. These fifth and sixth conductors 10, 11 may be used for instance as control conductors for electrical or electronic controls or may even be connected to a power supply as an additional power conductor for other electrical consumers. Support formations 12, 13 for an adapter inserted into the power track 1 are formed on -3the outer edges of the side walls remote from the base of the power track 1. In the illustrated embodiment, one of these support formations, specifically the support formation 13, is fitted with an additional bare ground conductor 14 that is exposed in the retaining channel 2. Each support rail 3 made of insulating material has a chamber, delimited by a first lateral bar 15, a center bar 16, and a second lateral bar 17, for receiving a phase conductor or neutral conductor 5, 6, 7, 8. The center bar 16 is forked in approximately a U-shape at its outer edge remote from the side wall of the support rail 1, to which the support rail 3 is fixed, the fifth or sixth conductor 10, 11 being inserted into the fork so that the conductor is positioned at the base of the fork and the fork legs 22 project sufficiently beyond the fifth and sixth conductors 10, 11 to prevent creep voltages between the conductors 5, 6, and 10 or 7, 8, and 11. The center bar 16 is of reduced thickness in the area between its base 18 and the insulating clips 19 holding the phase conductor 5, 6, or 7 or the neutral conductor 8 for forming an extended creep-voltage flow path. Empty spaces are formed between the support rail 3 made of insulating material and the side wall of the power track 1 holding it at the phase conductors 5, 6, 7 or neutral conductor 8. These chambers formed by these spaces are labeled 20. As may be seen from the drawing, the support rails 3 each carry the two phase conductors 5, 6 or the phase conductor 7 and the neutral conductor 8 in an outer plane extending parallel to the side wall of the power track 1. The fifth conductor 10 and the sixth conductor 11 are each arranged in a plane that is offset toward the interior of the power track 1 with respect to the outer plane. This embodiment also makes it possible for the additional fifth and sixth conductors 10, 11 to be arranged inside the power track 1 and to provide enough distance between the conductors to prevent leak currents. The outer edges of the first and second lateral bars 15, 17 and the ends of the fork legs 22 of the center bar 16 lie in an inner plane that also extends parallel to the side walls of the power track 1. All the conductors, that is, the phase conductors 5 through 7, the neutral conductor 8, and the fifth and sixth conductors 10, 11, are protected from manual contact in that they are recessed -4in the respective support rails 3. Not shown in the drawing is a coupling piece or the like that is inserted into the end of the power track 1 as a connector, input, or end piece. Such a coupling piece comprises insulating material and is in contact with the phase conductors, the neutral conductor, the fifth and sixth conductors, and with a ground contact of the power track 1 when it is inserted into the power track. When assembled in this way, parts of a dielectric coupling piece engage in the chambers 20 of the power track 1 that are formed between the support rail 3 and the side walls of the power track 1 and in a space 21 that is formed between the support bar for the fifth conductor 10 or sixth conductor 11 and the insulating bar 19 adjacent thereto that holds the part of each phase conductor 5, 6, 7 or of the neutral conductor 8 that is adjacent to the support bar. What this arrangement achieves is that the air gap is extended at the separation joint between the end of the power track 1 and the coupling piece inserted therein in terms of the air gap between the contacts so that a high degree of operational reliability is attained. The invention is not limited to the illustrated embodiment, but rather may vary widely within the context of the disclosure. All of the individual and combined features disclosed in the description and/or drawing are considered essential to the invention. -5-
