  The sliding cable duct 10 of this embodiment includes a cable duct body 16 that forms the side portion 12 and the back surface portion 14 of the sliding cable duct 10, and a sliding cable duct cover mechanism that forms the front portion of the sliding cable duct 10. 18. The cable duct main body 16 is a general-purpose one and is formed as a single piece. The cable duct main body 16 and the sliding cable duct cover mechanism 18 form an accommodation space S for accommodating a cable (electric wire).

(Sliding cable duct cover mechanism)
The sliding cable duct cover mechanism 18 includes a cable duct front portion 20 (hereinafter simply referred to as a front portion 20) that covers the front side of the sliding cable duct 10 and the front portion 20 in the front-rear direction (front and back directions) F1. A longitudinal movement mechanism 24 that can reciprocate in a sliding manner, and a front portion 20 that can reciprocate in a sliding manner in a cable duct short direction F2 (hereinafter simply referred to as a short direction F2) perpendicular to the longitudinal direction F1. A short-direction moving mechanism 26.

  The front part 20 is configured to be detachably engaged with the front side end part of the side part 12 of the cable duct body 16 at both left and right end parts when viewed from the front. The engaging structure Q is formed with the front side end of the. Further, the front part 20 has a DIN rail 30 on the front side. Here, the DIN rail 30 is a general-purpose rail for mounting the control device G, and the control device G can be mounted in a line in the vertical direction.

  The slide type cable duct cover mechanism 18 includes a front / rear direction slide plate 32 extending in parallel with the front / rear direction F1 from the rear surface side of the front portion 20 to the accommodation space S, and both side surfaces of the front / rear direction slide plate 32 so as to be slidable. And a front-rear direction guide member 34 for guiding from the front. The front-rear direction guide member 34 is attached to the back surface portion 14 of the cable duct body 16 and has a shape that extends in parallel to the front-rear direction F1 into the accommodation space S, and a groove portion 36 (see FIG. 3). The longitudinal movement mechanism 24 is formed by the longitudinal slide plate 32 and the longitudinal guide member 34. Further, the accommodation space S is divided into left and right by the front-rear direction guide member 34 and the front-rear direction slide plate 32.

  The sliding cable duct cover mechanism 18 is attached to the rear surface side of the front portion 20 and has a short-direction slide plate 42 having an engaging convex portion 40 parallel to the short-side direction F2 on the accommodation space S side. And an elongate short-side guide member 46 having an engaging concave portion 44 that engages with the mating convex portion 40 on the front direction side. An end portion of the front / rear direction slide plate 32 is fitted and fixed to the short direction guide member 46.

  The short direction moving mechanism 26 is formed by the short direction slide plate 42 and the short direction guide member 46. The engaging convex portion 40 has a truncated cone shape so that the vertical width gradually increases from the short-side slide plate 42 toward the accommodating space S, and the engaging convex portion 40 has a shape corresponding to this. Thus, the engagement convex portion 40 and the engagement concave portion 44 are not detached even when the front portion 20 is pulled out.

  With such a configuration, the front portion 20 does not slide in the front-rear direction (front-rear direction and the rear direction) or the left-right direction (short-side direction F2) in a state other than the intended time such as assembly work or maintenance work. .

(Function, effect)
Hereinafter, the operation and effect of the present embodiment will be described. In the present embodiment, the sliding cable duct 10 is mounted on the control panel C (see FIGS. 5 and 10) along the vertical direction. A cable K (see FIG. 10) is accommodated in the accommodation space S.

  In order to access the cable K accommodated in the sliding cable duct 10 for assembly work or maintenance work, first, the engagement between the side part 12 and the front part 20 is released. Since the cable duct body 16 is easily bent by pressing the side portion 12 with a finger from the left-right direction toward the center of the accommodation space S, this engagement is easily released.

  And the front part 20 is pulled out to the near side (front direction side). As a result, the front part 20 is positioned on the near side of the side part 12 and the movement of the front part 20 in the short direction F2 is not hindered by the side part 12.

  When the front part 20 is manually moved in the short direction F2, the front part 20 and the control device G are moved in the short direction F2, and the cable K accommodated in the accommodation space S is visually recognized from the front. It will be ready to. That is, the user can access the cable K with high work efficiency.

  Therefore, when the control device G and the cable duct body 16 are mounted in the same region when viewed from the front side, even if a large space is not formed on the side surface of the slide cable duct 10, The accommodation space S can be easily opened. Therefore, the slide type cable duct cover mechanism 18 and the slide type cable duct 10 that greatly improve the storage efficiency of the control device G in the control panel C without impairing the maintainability of the control device G can be obtained. Can be reduced in size.

  Further, since the front-rear direction moving mechanism 24 and the short-side direction moving mechanism 26 are slide-type moving mechanisms, the front portion 20 can be smoothly moved by a simple mechanism.

  In addition, after the assembly work and the maintenance work are finished and the access to the cable K is finished, the sliding cable duct 10 is easily housed (the cable K is housed and the front portion 20 is obtained) by performing the reverse procedure. Is engaged with the side portion 12).

  Further, by dividing the accommodation space S into left and right by the front / rear direction guide member 34 and the front / rear direction slide plate 32, the use of the control cable wiring route can be for clean and dirty, for in-panel wiring and for out-board wiring. Therefore, no duct separator is required, and the equipment can be downsized and the cost of the control panel C can be reduced.

  In the above description, the control device G is disposed in the vertical direction. However, when the sliding cable duct 10 is mounted on the control panel C, it is rotated by 90 °, that is, the DIN rail 30 is horizontal. Even when the control devices G are arranged in the direction and arranged in the horizontal direction, the same operation is performed.

  Further, a cavity (for example, a slit-shaped cavity 48) may be formed in the side portion 12 of the cable duct body 16. Thereby, since the accommodation space S communicates with the external space, the heat in the accommodation space S can be efficiently dissipated to the outside. Moreover, the weight reduction of the cable duct main body 16 is also realized.

[Second Embodiment]
Next, a second embodiment will be described. FIG. 5 is a plan sectional view showing that the slide type cable duct of the present embodiment is mounted on the control panel. In the sliding cable duct cover mechanism 18A of the present embodiment, the materials of the constituent members of the front portion 20A, the front-rear direction moving mechanism 24A, and the short direction moving mechanism 26A are made higher than those of the first embodiment. The shape is the same as that of the first embodiment (for example, a metal such as aluminum).

  In the present embodiment, heat generated from the control device G propagates to the front portion 20A. Then, it propagates to the short direction moving mechanism 26 </ b> A and the front / rear direction moving mechanism 24 </ b> A and is dissipated from these surfaces and the surface of the control panel C.

  Thereby, the control device G can be efficiently cooled by releasing the heat generated from the control device G mounted on the DIN rail 30 to the outside through the slide cable duct cover mechanism 18A. A control device having a large amount of heat generation can be mounted in the control panel. These effects become more prominent by forming the cavity 48 in the side portion 12 of the cable duct body 16 as described in the first embodiment.

  If the cable duct body 16 is also made of a material having a high thermal conductivity, the amount of heat radiated from the surface of the control panel C via the cable duct body 16 is large, so this cooling effect is further increased. Then, by increasing the contact area between the sliding cable duct and the control panel C, this cooling effect is further increased.

[Third Embodiment]

In the front portion 60, conductive tapes 62R and 62L are attached to both sides 30SR and 30SL on the back side of the DIN rail 30 so as to be electrically insulated from the DIN rail 30, respectively. The positive electrode 56P of the terminal block 56 and the conductive tape 62R are electrically connected by the embedded wiring 64R, and the negative electrode 56M of the terminal block 56 and the conductive tape 62L are electrically connected by the embedded wiring 64L.

  Each clamp for fixing the control device G to the DIN rail 30 is configured to be electrically connected to the positive electrode and the negative electrode of the control device G, respectively.

  In the present embodiment, the positive electrode and the negative electrode of the external power source (for example, DC 24V) are connected to the positive electrode 56P and the negative electrode 56M of the terminal block 56, respectively. The external power source connected to the terminal block 56 is electrically connected to the conductive tapes 62R and 62L through the non-electric shock routes, that is, the embedded wirings 64R and 64L. Therefore, by mounting the control device G on the DIN rail 30, it is possible to perform both the mounting process of the control device G on the DIN rail 30 and the wiring process of the external power source to the control device G at the same time. Can be greatly shortened.
