Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field J] The present invention relates to a power supply node box for interconnecting power lines.

[Background Art] Conventionally, this type of power supply box for interconnecting power supply wires has a fixed length, and because the wire connection terminals are etched on both end faces of the box, ″a
When the cut dimensions of #I vary, the aesthetic appearance may be impaired,
There was a problem that the live parts were exposed and there was a risk of electric shock. In other words, if the power line is cut shorter than the specified length or longer than the specified length, the electric wire box cannot be fixed in the specified position when the electric wire is connected normally, and the aesthetics of the room will be impaired. There is a problem that
In order to avoid spoiling the aesthetics of the power line when it is cut short, as shown in Figure 4, if you try to forcibly place the power supply light box The core wire portion (live portion) of the I4 source #lY that had been removed was exposed and there was a risk of electric shock.

[Objective of the Invention] The present invention has been made in view of the above-mentioned points, and its purpose is to prevent damage to the aesthetics of the room or the risk of electric shock even if the cutting dimensions of the power line vary slightly. Our goal is to provide a power supply intbox that will never run out of power.

[Disclosure of the Invention 1 (!R Construction) The present invention provides a power supply joint box in which wire connection terminal portions are provided at both ends of the box, and both types of wire connection terminal portions are electrically connected within the box. By providing electric wire connection terminals at the back of each closed surface of the open box, and by forming electric wire storage pockets at each opening of the box, the aesthetic appearance of the interior can be maintained even if the cut dimensions of the power wires vary slightly. This is to ensure that there is no risk of electric shock or damage to the equipment.

(Embodiment 1) Fig. 1 shows an embodiment of the present invention, in which a box 1 consisting of a body 1a and a cover 1b has M
Wire connection terminal parts 2 and 3 are provided, and both type wire connection terminal parts 2 and 3 are provided.
In a power joint box similar to the conventional example, in which electrical connections are made within the box 1 using an L-shaped metal fitting acjfi 6.7, the wire connection terminal portion 2 is located further back from each closed surface of the box 1, which is open at both ends. , 3, each opening of the box 1 has a wire storage pocket 4,
5 was formed. Here, each of the connection terminals 2a and 3a of the electric connection terminal part 2.3 is formed by a terminal fitting 10 and a U-shaped locking spring 11 that is internally installed in the U-shaped part 10a of the terminal fitting 10. It consists of connecting terminals,
By inserting the end of the power wire (core wire) from which the insulation coating has been removed into the wire insertion hole, it can be connected with one touch.

By the way, in the embodiment, the terminal fittings 10 of the wire connection terminal portions 2 and 3 are connected to the long holes 6a bored at both ends of the metal plates 6 and 7.
, 7a, the end on which the screw stopper 12a is formed, is slidably screwed by a child screw 12 and a washer 13 having one screw hole, and this sliding attachment means is used to attach the wire connecting terminal portion 2.3. The cast positions can be adjusted freely.

Further, a guide rib 14a is protruded from the body 1a for smooth movement of the wire connection terminal portions 2, 3, and the guide groove 14b of the wire connection terminal portions 2, 3 is engaged with this guide lip 14a. By matching them together, you can slide smoothly. Note that the metal plates 6 and 7 are fixed to the body 1a by screws 15, and the body 1a is attached to a building material by a mounting screw (not shown) inserted through a mounting screw hole 16. Also, body 1
A locking protrusion 1 is provided on the inner surface of the end portion of the cover 1b that is covered with the cover 1b.
7 is provided in a protruding manner, and the second locking protrusion 17 engages with a front locking gate 18 provided on the body 1a, thereby preventing the cover 1b from coming off.

(Example 2) Figure tIfI2 shows another example, in which connecting screws 20 are used as the connecting terminals 2a and 3a of the wire connecting terminal parts 2 and 3 to connect the electric wire to the terminal 4r. There is a wire storage pocket in each opening of box 1 for $4.
．． Both types of wire connection terminal portions 2 and 3 are provided so that 5 is provided.

Figure 3 shows the power supply box X1 and X2 according to the present invention.
It is an explanatory diagram showing the arrangement procedure of the tuna.
FFI/, ) 1 Yu Mayuzu Toto ^ ke dead individual consumption Naoko J, arrange the stock box XL at the predetermined position (inside left corner), and connect the power supply #lY as shown in Fig. 3(b). Connect the left end to the wire connection terminal section 3 of the power supply box X1.

Next, the power supply IIAY is cut to a predetermined length, the insulation coating on the right end is removed, and the power supply box X2, in which the right end of the power supply MY is connected to the wire connection terminal section 2, is assembled as shown in FIG.
As shown in c), it may be placed at a predetermined position (right corner). At this time, even if there are variations in the cut dimensions of the power wire Y, as long as the variations are less than the dimension Z of the wire storage pocket 4.5, the aesthetics of the room will not be impaired, and the live parts will be exposed. This eliminates the risk of electric shock. In addition, in the case of the first embodiment, since the arrangement positions of the wire connection terminal portions 2 and 3 are freely adjustable by the slide attachment means, variations in the wire storage pocket portions 4 and 5 are absorbed by this slide adjustment dimension. This will allow you to increase the amount.

[Effects of the Invention J As described above, the present invention provides a power supply node box in which wire connection terminal portions are provided at both ends of the box, and both types of wire connection terminal portions are electrically connected within the box, in which both ends are open. By providing wire connection terminals on each of the closed surfaces of the box, each opening of the box has a pocket for storing wires. Since it is covered by the power line storage pocket, there is an effect that even if the cut dimensions of the power line vary somewhat, the aesthetics of the room will not be spoiled or there will be no risk of electric shock.
