Referring to Figs. 1 to 3, the cable rack 1 includes a receiving portion 11 and a vertical portion 12.

One end of the receiving portion 11 is connected to the inner peripheral surface of the air-lit steel hole 2. Referring to Fig. 1, the receiving portion 11 protrudes inward from the inner circumferential surface of the air-

2 and 4, the aerial lighting steel hole 2 is illustratively used to provide the connection of the power cable of the aerial lighting 3 and the installation space of the isolation transformer 4 for aviation equipments have. An example of a specific sub-configuration of the air-lit steel ball 2 will be described later.

1 to 3, the vertical portion 12 extends upwardly from the other end of the receiving portion 11. As shown in Fig.

Illustratively, the vertical portion 12 may be formed in a direction perpendicular to the receiving portion 11, as shown in Figs. The present cable rack 1 may have an L shape as shown in Figs.

Referring to Figs. 2 and 3, the receiving portion 11 and the vertical portion 12 form a mounting space 17 in which the cable 0 for air conditioning is mounted.

Illustratively, the cable (0) for aerial lighting can be mounted on the mounting space (17) a plurality of times along the circumference of the inner circumferential surface of the aerial lighting steel hole (2). In this case, the air-conditioning cable 0 can be stacked in the mounting space 17 in a plurality of layers.

At this time, the fact that the air-conditioning cables 0 are laminated sequentially is not limited to the fact that the air-conditioning cable 0 is laminated on the upper side in the vertical direction so as to be positioned on one straight line as shown in Fig. 3, But it means that the cable for airplane equipments 0 is stacked at a somewhat oblique angle.

That is, the width set in advance is set so that the cable 0 for air conditioning can be mounted on the stationary space 17, while the cable 0 for air conditioning is arranged side by side in the width direction (3 o'clock-9 o'clock direction in Fig. 3) And can be set within a range of width that prevents being arranged and mounted. It is preferable that the preset width of the receiving portion 11 is set to a width that takes into consideration the diameter of the air-lighting cable 0 to be mounted on the receiving portion 11 and a predetermined tolerance.

If the width of the receiving portion 11 is excessively large, the space occupied by the receiving portion 11 in the air hole 2 is increased, and when the insulating transformer 4 for aviation equipments is mounted or maintained The work space in which the work is performed is reduced. Therefore, it is necessary for the receiving portion 11 to have a width capable of mounting the air-conditioning cable 0 and ensuring the maximum working space.

That is, the receiving portion 11 has a predetermined width for sequentially stacking the air-conditioning cable 0 in the mounting space 17, so that the air-illuminating cable 0, which is placed in the mounting space 17, It is possible to accommodate the air-conditioning cable 0 while closely contacting the inner circumferential surface of the air-conditioning steel hole 2, thereby maximizing the work space.

Further, since the receiving portion 11 is formed to have a predetermined width, it is possible to prevent the air conditioning cable 0 from becoming entangled in the mounting space 17.

Illustratively, as shown in FIG. 3, if the cable 0 for air conditioning is mounted in a plurality of layers in the mounting space 17, if the width of the receiving portion 11 is too large, You can get tangled together. However, according to the present cable rack 1, when the support portion 11 is formed to have a predetermined width, when the air-conditioning cable 0 is mounted in a plurality of layers in the mounting space 17, , It is possible to prevent the air conditioning cable (0) from becoming entangled in the mounting space (17).

As a result, the stability of the state of the cable 0 for air conditioning can be improved and the cleanliness of the air conditioning cable 0 can be improved.

If the width of the receiving portion 11 is too large, the cable for air conditioning 0 can flow in the mounting space 17, and the mounted cable for air-conditioning 0 can be separated from the mounting space 17 .

However, according to the present cable rack 1, since the receiving portion 11 is formed to have a predetermined width, it is possible to fix and fix the cable 0 for aviation equipments stably mounted on the cable rack 1.

3, the cable rack 1 includes an insulating layer 13 formed on the upper surface of the receiving portion 11 and the surface of the vertical portion 12 facing the inner circumferential surface of the air- can do.

The upper surface of the receiving portion 11 and the surface of the vertical portion 12 facing the inner circumferential surface of the airtight steel hole 2 when the cable 0 for air- (0). Therefore, even if the outer cover of the air-conditioning cable 0 is damaged, the insulation protection can be achieved.

For the purpose of maximizing insulation protection, an insulation layer 13 may be formed on the entire surface of the cable rack 1, as shown in FIG.

The insulating layer 13 may be, for example, a polyvinyl chloride tube.

Vinyl tubes are made of a mixture of vinyl chloride resin as the main component. They are used for wire insulation of electrical appliances, telecommunication equipment and measuring instruments because they are flame retardant, have excellent resistance to oil and grease, chemical resistance and abundant flexibility.

The vertical section 12 is provided so that its upper end corresponds to the insertion port 2111 so that the air conditioning cable 0 drawn through the insertion port 2111 extends along the circumference of the inner circumferential surface from the upper side of the lower housing 21 Can be. Accordingly, when the operator arranges or mounts the air-conditioning cable 0 on the cable rack 1, the operation can be facilitated.

Since the cable rack 1 is disposed on the upper side in the lower housing 21 as described above, the work space on the lower side of the lower housing 21 can be secured more widely, The operation for mounting or maintenance of the vehicle can be made easier.

It is preferable that the height of the vertical portion 12 is set to a height at which the air conditioning cable 17 can be sequentially stacked in the mounting space 17 as desired.

1, 2 and 4, a flange 213 protruding inward along the periphery of the opening of the lower housing 21 may be formed.

At this time, as shown in FIG. 2, the receiving portion 11 may be formed so as to protrude less inward than the flange 213. That is, the receiving portion 11 may have a protruding length smaller than the protruding length of the flange 213.

1, when the flange 213 is formed along the periphery of the opening of the lower housing 21, there is a side in which the accessibility of the operator is hardly ensured in the space right under the flange 213.

That is, since the support part 11 is formed so as not to protrude inwardly of the flange 213, the cable hanger 1 can utilize the lower space of the flange 213, which is relatively difficult for the operator to access, 0) can be mounted in a space-efficient manner, so that the range of the working space available to the operator in the lower housing 21 can be maximized.

The width of the receiving portion 11 of the present cable fastener 1 can be set in consideration of the previously set width and the length of the flange 213 protruding inward of the lower housing 21. [

In other words, the receiving portion 11 is formed so that the air-illuminating cable 0 can be sequentially stacked, and the receiving portion 11 can be formed so as not to project further inward than the flange 213.
