DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring box to which a conduit is connected and in which a cable or the like inserted in the conduit is housed.

[0002]

2. Description of the Related Art In general, a cable routed behind a wall of a building is arranged on a peripheral wall of a wiring box placed behind the wall and connected to the wiring box so as to communicate with the inside of the wiring box. And is wired in the wiring box.

[0003] This type of wiring box is formed in a rectangular box shape having an opening by a synthetic resin material. And
A tubular pipe connecting portion into which a conduit can be inserted and connected is protrudingly formed on one of the upper and lower side walls. A mounting hole is formed on one side of the wiring box.

[0004] In this mounting hole, a wiring box is mounted on a pillar, a C-shaped steel, or the like constructed on the back side of the wall using mounting screws. Furthermore, the conduit is moved in the axial direction of the pipe connection part, the end of the conduit is inserted into the opening of the pipe connection part, the conduit is connected to the wiring box, and the cable is inserted through the conduit. Cables were routed inside the wiring box.

[0005]

For example, when installing a wiring box in a true wall of a wooden building, first, a plurality of bamboo bamboos laid in a lattice pattern between pillars are cut off to insert the wiring box. Holes are formed. Then, a wiring box is inserted between the bamboo bamboos through the hole and attached to the pillar. Thereafter, the end portion of the conduit is moved toward the tube connecting portion and inserted and connected.

In this case, a plurality of bamboo bamboos are assembled in a grid around the hole. Therefore, when the conduit is moved in the axial direction of the tube connecting portion, the bamboo bamboo becomes an obstacle, and there is a problem that it is very difficult to perform the operation of inserting and connecting the conduit to the tube connecting portion.

The wiring box is often installed in a wall near the floor. In this case, when connecting the conduit to the lower side of the wiring box, the distance between the wall surface on the lower end side of the wiring box and the floor is short, and it is difficult to expand and contract and bend the conduit. It is difficult to move the pipe connection part in the axial direction, and there is a problem that it is very troublesome to insert and connect the conduit into the pipe connection part.

Conversely, if it becomes necessary to release the connection after the conduit has been connected, it is difficult to move the conduit in the axial direction so as to pull out the conduit from the tube connection. There is a problem that it is very troublesome to extract the conduit.

The present invention has been made by paying attention to such problems existing in the prior art. An object of the present invention is to provide a wiring box capable of easily and reliably performing a connection or extraction operation of a conduit.

[0010]

A restricting portion 37 that protrudes inward and whose inner peripheral surface forms an arc shape is formed. On the inner peripheral surface of the tube connecting portion 31 facing the regulating portion 37, a ridge 38 as a locking portion is formed so as to protrude along the lateral direction of the tube connecting portion 31. Then, when the conduit 33 is connected to the conduit connection portion 31, the ridge 38 and the restricting portion 37 can prevent the conduit 33 from coming out of the conduit connection portion 31 upward and sideward. I have.

As shown in FIG. 2 and FIG.
A protrusion 39 is formed at the center on the bottom wall 17 side, and a screw hole 40 is formed at the center thereof. Then, as shown in FIG. 4, between the rear surfaces of the pair of pipe connection portions 31 and the protrusion 39, the steel 4
When the screw 29 is inserted into the screw hole 40 and the screw 29 is inserted, the steel material 41 can be prevented from falling out in the vertical direction by the head 29a of the screw 29.

As shown in FIG. 1, on the bottom wall 17 of the box main body 12, a cylindrical fixing portion 42 is provided at a position inward of the pair of short side walls 14 so that the front end thereof faces the opening. And a fixing hole 43 is formed at the center thereof. As shown by the two-dot chain line in FIG.
Reference numeral 4 denotes a rectangular shape made of a synthetic resin material or the like, and a holding hole 45 capable of holding a wiring device such as a switch is formed in the center thereof. Holes (not shown) corresponding to the fixing holes 43 of the wiring box 11 are formed at both upper and lower ends of the wiring device mounting frame 44. Then, the screw 46 shown by a two-dot chain line in FIG. 10 is screwed into the fixing hole 43 from the hole of the wiring device mounting frame 44 so that the wiring device mounting frame 44 can be mounted on the wiring box 11.

The operation of the wiring box 11 will be described below. As shown in FIG. 4, the long side wall 15 on which the claw portion 18 is formed is formed with respect to the C-shaped steel 25.
And the back surface of the claw portion 18 is engaged with the C-shaped steel 25. Further, the mounting screw 2 is inserted through the circular hole 20 of the through hole 22.
3 and the mounting screw 23 is inserted into a hole formed in the C-shaped steel 25 in advance. And the wiring box 1
1 is moved to a predetermined position.
Then, a screw-in wiring box 11 is attached and fixed to 5.

At this time, since the circular hole 20 of the through-hole 22 is connected to the groove 21 extending linearly, the wiring box 11 is moved around the mounting screw 23 by the length of the groove 21.
The wiring box 11 can be moved in the longitudinal direction, and the wiring box 11 can be securely fixed at a predetermined position. Also,
Since the outer surface of the claw portion 18 and the outer surface of the long side wall 15 are connected in an arc shape, they engage with the arc-shaped corner portion of the C-shaped steel 25.

Next, as shown in FIG. 5A, when the cable-containing conduit tube 32 is inserted through the opening of the tube connecting portion 31, the slit 36 of the tube connecting portion 31 is inserted as shown in FIG. 5B. The distal end side is elastically deformed with the insertion of the conduit tube 33 and expands outward. At this time, the expansion is smoothly performed by the slit 36, and the insertion of the conduit tube 33 can be easily performed. Further, after the conduit 33 has passed through the opening, the outer tube connecting portion 31 is elastically deformed and reduced in diameter to return to the original state. Also at this time, the diameter of the pipe connection portion 31 is smoothly reduced by the slit 36.

The base end of the pipe connection part 31 fixed on the short side wall 14 is shorter than the pipe connection part 31 on the distal end side of the slit 36. Therefore, when the conduit tube 33 is inserted into the tube connection portion 31, the base end side of the tube connection portion 31 is closer to the base end side of the tube connection portion 31 than when it is formed to have the same length as the distal end portion side. The resistance can be reduced, and the insertion operation of the conduit tube 33 can be easily performed.

As shown in FIG. 5C, when the conduit tube 33 is connected to the tube connection portion 31, the ridges 38 formed on the inner peripheral surface of the tube connection portion 31 become concave ridges 35 of the conduit tube 33. To lock. A restricting portion 37 protrudes from an opening of the pipe connecting portion 31 so as to face the protruding ridge 38. Therefore, the restricting portion 37 presses the conduit tube 33 inward of the tube connecting portion 31, and the protruding ridge 38 is firmly locked to the concave ridge 35. In addition, since the inner peripheral surface of the regulating portion 37 is formed in an arc shape, the restricting portion 37 surely comes into contact with the outer peripheral surface of the conduit tube 33. Therefore, the projecting ridge 38 and the restricting portion 37 can reliably prevent the conduit 33 from coming off in the axial direction and sideways.

When the cable conduit 33 is pulled out from the
Is pulled out to connect the conduit tube 33 to the wiring box 11.
Can be extracted from

Therefore, even if the distance between the lower end surface of the wiring box 11 and the floor surface is short, there is no need to move the conduit 33 in the axial direction, and the connection of the conduit 33 to the conduit connection portion 31 is not required. Alternatively, the extraction operation can be performed easily and reliably.
