Description

  The present invention relates to a wire connector for connecting wires wired indoors or the like to supply power.

  Conventionally, this kind of wire connector is used for indoor wiring in general houses, stores, building facilities, etc., for example, in Patent Document 1, especially in paragraph number [0001], it is used for buildings such as houses and buildings. In the connector for electric wire connection, paragraph numbers [0003] and [0013] show a plug-in type connector that can securely connect the electric wire with one touch.

  On the other hand, in recent years, lighting fixtures using light-emitting diodes with DC as a power source have been widely used, and these lighting fixtures are used in indoor wiring that is currently AC-distributed. Configured by providing a power supply unit that converts to direct current, connect the lighting fixtures that incorporate these DC power supply units to the wires wired indoors, using the above-described plug connectors, joint boxes and other wire connectors Have been used.

  For this reason, in order to be able to use these lighting fixtures without incorporating a DC power supply unit, for example, in Patent Document 2, particularly paragraph number [0003], a DC power supply device is installed in a distribution board such as a house. The AC / DC converter is converted into a DC power source, and a DC power source is supplied to a DC device from a DC outlet having a pair of positive and negative power supply units installed in each room via a DC supply circuit. A DC power distribution system has been proposed.

  However, when multiple lighting fixtures are installed on an electric wire wired indoors, the voltage drop occurs due to the long electric circuit for the appliances that are far from the power source due to the long electric circuit, and it lights at a predetermined brightness. A problem that cannot be done arises. In particular, when a direct current distribution system such as that disclosed in Patent Document 2 is used, a weak voltage distribution of about 48 V or 24 V is obtained, and it is more susceptible to a voltage drop. In addition, in an inverter device or the like, there is a possibility that an energization current to the electric wire in the electric circuit increases due to an increase in the correction current value due to the voltage drop.

  In Patent Document 2, in particular, paragraph [0008], a direct current supply line connected to the direct current power supply device is arranged in a loop so that the direct current in the loop is placed between the direct current power supply device and the direct current equipment. Two paths are formed from the connection point of the power supply device in one direction along the loop and a route in the other direction, and the impedance between the direct current power supply device and the direct current device is reduced, resulting in the direct current supply line. It is described that the voltage drop is kept small. However, in paragraph [0052], direct current outlets such as direct current outlets and hook ceilings are arranged at a plurality of locations on the loop formed by the direct current supply line, and direct current equipment is connected to the direct current outlets to connect direct current equipment. It only describes that DC power is supplied from a power supply device to a DC device via a DC supply line, and does not mention how to wire and construct a loop-shaped electric circuit indoors.

  However, the work of wiring a long DC supply line, that is, a long loop-shaped electric circuit indoors, causes a problem that the construction becomes complicated because the length and number of the electric wires increase. In addition, in stores and building facilities, the length of electric wires that run indoors is long, so loop-shaped electric circuits are inevitably long, making it difficult to keep the impedance of the electric circuit small, making it far from the power source. There is also a problem that it is difficult to suppress the voltage drop at the end of the loop.

  The present invention has been made in order to solve the above-described problem. A wire connection capable of suppressing a voltage drop by forming a loop-shaped electric circuit in a long electric circuit by a simple means and facilitating the construction. Is to provide a vessel.

First, the open end (the open end on the left in FIG. 2) of the red electric wire 11w1 connected to the first and second terminal portions 11 and 12 and the yellow electric wire 12w1 are connected by the closed electric wire w1. Further, the open end portion (the open end portion on the right side in FIG. 2) of the red feed wire 11w2 and the yellow feed wire 12w2 connected to the first and second terminal portions 11 and 12 is connected by the closed wire w2. The Thereby, a loop-shaped electric circuit L1 on the + pole side is formed.

  Similarly, the open end (the open end on the left in FIG. 2) of the blue electric wire 13w1 connected to the third and fourth terminal portions 13 and 14 and the green electric wire 14w1 are connected by the closed electric wire w3. .

In addition, each electric wire and feed electric wire made of F cable for constituting each loop-shaped electric circuit is wired by being stretched around a ceiling or the like in a store or the like, and is provided at a predetermined portion of the electric circuits L1 and L2 forming the loop shape. A DC power distribution device S is configured by connecting DC output portions such as the DC outlet C and the hooking ceiling H. In addition, in FIG. 2, each electric circuit L1 and L2 was expanded and illustrated up and down for convenience.

Note that each of the lighting fixtures D1 and D2 is configured as a fixture dedicated to a DC power distribution device, and unlike a fixture used in a conventional AC power distribution device, each of the lighting fixtures D1 and D2 has an individual DC power supply unit for lighting a light emitting diode. It is configured as a simple lighting fixture that does not. When the lighting fixtures D1 and D2 are turned on, the voltage drop is suppressed by the loop-shaped electric circuits L1 and L2. Therefore, the lighting fixtures D2 that are far from the DC power supply unit 18 and the lighting fixtures D1 that are close to each other are also predetermined. Illumination with a predetermined brightness can be performed by supplying a rated DC voltage.

  That is, since the electric circuits L1 and L2 are formed in a loop shape, between the DC power supply unit 18 and each of the lighting fixtures D1 and D2 that are loads connected to the loop electric circuit, A case where two paths, a path extending in one direction along the loop from the connection point of the DC power supply unit 18 and a path extending in the other direction, are formed along the loop, and are formed by a single electric circuit as in the past.

It is possible to reliably form a loop-shaped electric circuit in the electric circuit. At the same time, a complicated operation for configuring the loop-shaped electric circuit becomes unnecessary, the work for configuring the loop-shaped electric circuit is simplified, and workability can be improved.
