Recently, as shown in Fig. 2, the body part 10 is manufactured in the form of a horizontal partition wall 11 formed therein using an "H" channel, The communication cables are separated from the upper and lower portions of the horizontal partition wall 11 and then the upper and lower covers 20 and 60 are attached to the upper and lower openings of the body 10, A raceway has been developed in which various electric and communication cables disposed inside the body 10 are short-circuited or electrical characteristics are deteriorated by mounting the lighting device A on the bottom surface of the lower cover 60.

However, in the conventional raceway as described above, since the horizontal partition wall 11 is not provided inside the connection case 30, various electric and communication cables are combined and tangled within the connection case 30, And there is a great risk that the electrical properties will deteriorate.

In addition, in the conventional raceway, it is very difficult to mount the lower cover 60 because the cable disposed below the horizontal partition wall 11 is struck down by its own weight. To prevent this, The work must be fixed to the body part 10. Such an operation is performed in the form of a top-view operation, and thus there is a problem that workability is largely poor.

Since the connecting body 30 has a structure in which the engaging portion of the cross-sectional shape is protruded and fixed to the body 10 in the direction in which the body 10 is engaged, There arises a problem that different types of connecting sleeves 30 must be manufactured.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. The same reference numerals are used for the same components, and only the different portions are described for the sake of clarity.

3 to 7, the raceway for fixing a lighting fixture of the present invention includes a body 110 having a lighting unit (not shown) fixed on a bottom surface thereof, And a connection case 130 connected to the body 110.

The body part 110 according to the present invention is formed in a channel shape having an opened upper part formed of a bottom part and a side wall part extending upward from both sides of the bottom part. The upper cover 120 is coupled to the upper part of the opened body part 110.

The connecting body 130 is divided into a lower body 131 and an upper body 132.

The lower body 131 has a sidewall having a predetermined height along the bottom and is open at an upper portion. Each side wall has a body communication groove 133 formed by cutting the upper end of the sidewall so that the upper end is opened.

The upper body 132 has a side wall having a predetermined height along the upper surface, and a lower portion is opened. Each side wall is formed with a body portion communication groove 133 formed by cutting the lower end of the side wall so as to open the lower end.

The body communicating groove 133 of the upper body 132 and the body communicating groove 133 of the lower body 131 are formed at positions corresponding to each other and facing each other.

The body portion communication grooves 133 formed in the upper body 132 and the lower body 131 may be formed on all the side walls or only on the side walls communicating with the body 110. The body communicating groove 133 may be formed such that the side wall is cracked and the cracked portion is separated from the side wall only when the operator applies a force more than a predetermined amount by the hand.

A screw engagement piece 134 is formed at an upper corner of the lower body 131. The screw fastening piece 134 is formed to be bent horizontally from the side wall of the lower body 131 toward the inside of the lower body 131, and a screw fastening hole 134a is formed at the center thereof. A screw through hole 132a corresponding to the screw fastening piece 134 is formed at the corner of the upper body 132. The lower body 131 and the upper body 132 are tightly coupled with each other by a fastening screw 136 which is passed through the screw through hole 132a and fastened to the screw fastening hole 134a of the screw fastening piece 134 .

On the inner side of the lower body 131, a first upper and lower partitioning member 137 for vertically dividing the lower body 131 and the upper body 132 is disposed. The first upper and lower partitioning member 137 includes a horizontal upper plate 137a formed with cutouts for avoiding interference with the screw coupling pieces 134 of the lower body 131 and a lower upper plate 137b bent downward from the horizontal upper plate 137a, 131). The height of the horizontal upper plate 137a is set to be equal to the height of the upper end of the lower body 131 so that the first upper and lower partitioning members 137 divide the lower body 131 and the upper body 132 precisely .

The body 110 is connected to the lower body 131 through a connecting member 140. The connection member 140 includes a connection panel 141 having one end engaged with the body 110 and a first screw 142 passing through the lower body 131 and coupled to the other end of the connection panel 141, And a second screw 143 that passes through the connection panel 141 and is fastened to the bottom of the body 110.

In this case, a coupling groove 141a is formed in the bottom surface of the connection panel 141 along the longitudinal direction, and a coupling protrusion 111 (see FIG. 1), which is fitted into the coupling groove 141a, May be formed.

A groove 112 is formed at the center of the coupling protrusion 111 and a second screw 143 is coupled to the coupling protrusion 111 along the longitudinal direction of the coupling protrusion 111. At the bottom of the coupling panel 141, And a plurality of second engagement grooves 141b to which the first engagement grooves 142 are coupled may be formed to be parallel to each other along the length direction. A through hole 131a through which the first screw 142 passes is formed on the side wall of the lower body 131. [

Meanwhile, the left and right partition panels 150 may be provided in the body 110. The left and right partition panel 150 includes a horizontal part 151 formed with a protrusion 151a to be fitted into the groove 112 of the coupling protrusion 111 and a body part 110 extending from the horizontal part 151, And a vertical part 152 extending vertically to the upper end of the body part 110 and dividing the inside of the body part 110 to the left and right. In this case, the left and right partition panels 150 can separate the cables passing through the inside of the body 110 left and right.

The body 110 may further include a second upper and lower partition member 160 placed on the bottom of the connection panel 141 to divide the inside of the body 110 up and down. The second upper and lower partition member 160 is installed in a coupling section of the connection panel 141, which is difficult to install in the left and right partition panels 150, to separate the cables passing through this section in the vertical direction.

The second upper and lower partitioning member 160 does not move in the forward and backward directions inside the body 110 because both ends of the second upper and lower partitioning member 160 are closely contacted to the coupling body 130 with the ends of the left and right partitioning panels 150.

The lighting apparatus fixing raceway having the above-described structure fixes the connection member 140 to the body 110 with the second screw 143 and then fixes the connection member 140 using the first screw 142. [ And then the anchor bolts and the anchors fixed to the ceiling are fixed to the ceiling of the body 110 to securely fix the ceiling.

After the lighting device is installed on the bottom surface of the body part 110, cables extending from the lighting device are disposed inside the body part 110. At this time, the left and right partition panels 150 are coupled to the inside of the body 110, and the upper body 132 is not coupled to the lower body 131, but only the first upper and lower partitioning members 137 are connected to the lower body 131 ). ≪ / RTI >

Various communication cables and electric cables installed in the body 110 are separated and arranged on the left and right sides of the left and right partition panels 150 in the process of passing through the body 110. Therefore, a phenomenon of deterioration of short-circuiting and electrical characteristics between the cables is prevented.

In addition, since the cables passing through the inside of the body part 110 are separated and disposed in the left and right direction through the left and right partitioning panels 150 in a state of being seated inside the body part 110, It is possible to perform the excretion operation very easily and easily without a difficult top view such as fixing the cable to be sagged down and fixing the lower cover to the opened lower part of the body part 110 because the lower part is opened.

The partitioned portion of the left and right cables is inserted into the coupling housing 130 through the body communication groove 133 of the lower body 131 after passing through the left and right partitioning panels 150, (Right side) is discharged to the body 110 connected to the other side of the coupling 130 via the upper part of the first upper and lower partitioning member 137. Therefore, since the cables disposed inside the coupling housing 130 do not overlap or tangle, the short-circuit between the cables and electrical characteristics are not deteriorated.

Since the groove 112 is formed on the bottom of the connecting member 140 so that the protrusion 151a of the left and right partitioning panels 150 can be fitted to the bottom of the connecting member 140, The left and right partition panels 150 can not be installed. Accordingly, when the second upper and lower partitioning member 160 is provided in the body 110, the second upper and lower partitioning member 160 divides the cables that pass through the left and right partitioning panels 150 into upper and lower portions, The cables, which have exited through the connector 150, can be stably installed without being overlapped or tangled in the process of being inserted into the connector housing 130.

Since the connection housing 130 is selectively connected to the body 110 in various directions using the separate chain connection panel 141, the connection body 130 can be connected to the body 110 in various ways depending on the connection direction of the body 110, Since it is not necessary to produce the shape of the branch, the manufacturing cost is low and the specification management is easy.

When the upper cover 120 is assembled to the opened upper end of the body part 110 and the upper cover 120 is assembled to the lower cover after the completion of the laying of the cable, the operation of draining the cable is completed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be takeners of ordinary skill in the art, And such variations are within the scope of the present invention.
