Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device which can easily connect internal wiring and external wiring in a showcase including a boat bottom type body case.

[0002]

2. Description of the Related Art As this type of showcase, a cold air circulation type open showcase shown in FIG. 4 is known. In the figure, the main body case 1 of the open showcase is an outer box 2 and an inner box 3 whose front surface is open and whose lower portion is formed of a heat insulation wall in a boat bottom shape.
The cold air circulation path 4 is formed between the outer box 2 and the inner box 3, and the inside 5 is formed inside the inner box. A fan 41 and a cooler 42 are arranged in the cold air circulation path 4, and
Is divided into upper and lower stages by shelves 51, and a canopy at the front end of the shelves 51 and at the upper front end of the main body case 1 is provided with fluorescent lamps 52 for illuminating the inside 5 and the front side of the open showcase, respectively. Further, on the lower front surface of the outer box 2, a wiring duct 71 is formed by a receiving plate 21 having a rear end portion fixed to the outer box 2 and projecting forward and a decorative panel 22 covering the front surface of the outer box. As shown in FIGS. 5 and 6, the wiring device 7 is provided with a mounting plate 72 whose upper end is fixed to the outer box 2 in the wiring duct 71, and the terminal plate 73 is supported by the mounting plate 72. Is installed. The lead wire 75, which is an internal wiring of the fan 41 and the fluorescent lamp 52, is drawn into the wiring duct 71 and guided from the back side to the front side through the through hole of the mounting plate 72, and the terminal at the tip is closely attached to the upper terminal of the terminal plate 73. Then, the machine screw 73a is tightened and connected.

On the other hand, a lead wire 76 having one end connected to a power source and serving as an external wiring has a terminal at the other end inserted and closely attached to a lower terminal of a terminal plate 73 and tightened and connected by a small screw 73b. Then, the internal wiring and the external wiring are connected via the terminal board 73, and the fan 41, the fluorescent lamp 52 and the like are supplied with power from the power source. The above open showcase has 5 shelves and 51 shelves.
The goods are effectively displayed and stored by using. Further, the inside air of the refrigerator is circulated through the cooler 42 by the fan 41 that is supplied with power via the wiring device 7, and this cold air flow
A cold air curtain is formed in the front opening of the container, and the inside of the refrigerator 5 is cooled and kept cool.

By the way, in the conventional open showcase, in order to connect the lead wire 75 to the terminal board 73, the lead wire 75 is mounted through the through hole from the narrow gap between the front surface of the outer box and the mounting plate 72. The connection work is extremely troublesome because it has to be connected to the lead-out terminal board 73 at the front of the board.
Further, when it is desired to increase the internal wiring by adding an electric circuit, it is difficult to reattach the mounting plate 72 to which the lead wire 75 is connected once it is removed from the outer box.
6 has a drawback in that the new internal wiring cannot be sent to the rear of the mounting plate due to an obstacle and it is almost difficult to newly carry out the internal wiring.

An object of the present invention is to provide a wiring device for a showcase, which can easily connect the internal wiring and can easily cope with the expansion of the internal wiring due to the addition of an electric circuit or the like.

[0006]

In order to achieve the above object, according to the present invention, a mounting plate is provided on a lower front surface of an outer box formed in a boat bottom shape of a main body case, and the main body is mounted on the mounting plate. In a wiring device for a showcase in which a terminal plate for connecting internal wiring and external wiring of a case is installed, a receiving plate fixed to the front surface of the bottom of the outer box and protruding forward is provided, and the mounting plate is rotated forward. A lower end of the mounting plate is movably supported by a hinge on the receiving plate, and an upper end of the mounting plate is detachably fixed on the front surface of the outer box.

[0007]

If the terminal plate is tilted forward to connect the internal wiring, a large working space is provided in the rear, and the connecting work can be easily performed. Also, if you want to increase the number of internal wiring, if you keep the existing wiring and release the upper fixing of the mounting plate and tilt it forward, a gap that can sufficiently insert new wiring between the upper end of the mounting plate and the front of the outer box. You can Therefore, the internal wiring can be easily added.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show an embodiment of the present invention, in which parts common to or the same as those in FIGS. 4 to 6 are designated by the same reference numerals. 1 to 3, a mounting plate 78 is formed in a hook shape having a leg 78a bent rearward from the lower end, and one hinge piece is fixed to the mounting plate 78 and the other hinge piece is fixed to the receiving plate 21. A small screw 7 supported at its lower end by the hinge 79a supported by the receiving plate 21 and detachable.
The upper end portion is detachably fixed on the front surface of the outer box 2 by 9b and installed in the wiring duct 71. The terminal plate 73 is attached to the attachment plate 78 as in the conventional case, and a through hole for passing the internal wiring is provided.

In the above structure, when connecting the lead wire 75 to the terminal plate 73, the small screw 79b is removed and the mounting plate 78 is tilted forward as shown in FIG. As a result, a large space is formed between the front surface of the outer box 2 in the wiring duct 71 and the mounting plate 73. Then, the lead wire 75 is guided onto the leg 78a, and the terminal at the tip is easily connected to the upper terminal of the terminal board 73 through the through hole by utilizing the space. Rear leg 78
The mounting plate 78 holding the lead wire 75 at a is rotated backward, and the upper end is fixed to the outer box 2 with the small screw 79b, and the wiring work is completed. In this way, the lead wire 75 is easily wired and connected. When it is desired to increase the number of internal wirings, the mounting plate 78 can be easily tilted forward while holding the lead wire 75 on the leg 78a by removing the small screw 79b as described above. Therefore, the lead wire to be added can be fed to the rear of the mounting plate 78 through the gap formed between the front surface of the outer box and the upper end of the mounting plate, and the wiring work of the additional lead wire 75 can be easily performed. Further, in this wiring device 7, since the mounting plate 78 is held by the small screws 79b and the hinge 79a at the top and bottom unlike the conventional case, the work is easily and surely performed when the lead wire 76 is connected to the terminal plate 73. There is an advantage that it is also useful for solving problems such as insufficient tightening of the small screws 73b, or the lead wire 76 being pushed backward sometimes to cause bending stress in the lead wire 76.

[0010]

According to the present invention, the mounting plate is provided on the lower front surface of the outer case formed in the boat bottom shape of the main body case, and the terminal for connecting the internal wiring and the external wiring of the main body case to the mounting plate. In the wiring device of the showcase where the board is installed,
A receiving plate that is fixed to the front surface of the bottom of the outer box and projects forward is provided, the lower end of the mounting plate is supported by the receiving plate so as to be pivotable forward, and the upper end of the mounting plate is detachable. Since it is fixed on the front surface, a large work space can be obtained by tilting the mounting plate forward during the work of the internal wiring, and the wiring work can be easily performed. In addition, the internal wiring can be added by tilting the mounting plate so that new wiring can be sent to the rear of the mounting plate, and it is possible to add the wiring without difficulty. Further, in connection of the external wiring, there is an advantage that factors such as insufficient tightening are eliminated and the connection is surely performed.
