Abstract

PURPOSE:To obtain a cable holding device which has good workability and can easily hold and fix cables passed through a rectangular hole formed on a panel surface of a box body even when the connector section of the cable 3 is in the box body. CONSTITUTION:U-shaped grooves 13a and 13b are formed in corresponding to the cross-sectional shapes of cables 3 on one side faces of two holding bases 12a and 12b in their longitudinal direction and projecting sections are respectively provided on the lower surface of the bases 12a and 12b. After the cables 3 are put between the bases 12a and 12b, the bases 12a and 12b are coupled so as to hold the cables 3 in the holes formed of the grooves 13a and 13b. When the projecting sections on the lower surfaces of the bases 12a and 12b are put in a rectangular hole 4 on a panel surface 2, the coupled two holding bases 12a and 12b and panel surface 2 can be fixed to each other.

[Detailed description of the invention]

[Purpose of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable holding device for connecting cables inside a box such as a control panel.

0002

2. Description of the Related Art When a control panel or the like is installed in a place with severe environmental conditions, such as outdoors, if a connector section is provided outside the control panel, the connector section will rust or attract dust. Also, if the cables are large or the number of cables increases, stress will be placed on the connectors, making them more likely to break. For this reason, conventionally a connector part, which is a joint part of the cable, was provided inside the box.

0003

[Problems to be Solved by the Invention] A holding structure for cables connected inside a box for the purpose of dustproofing, drip-proofing, etc. is as shown in FIG. Open and connect the cable 3 to the two divided plates 5a and 5b.
Drill a large elongated hole 6 according to the thickness of the hole, and insert it into the screw 8.
The cable 3 and the elongated hole 6 are fixed to the panel surface 2 with a sealing material 7 and held. Therefore, there is a problem that the work is time-consuming.

Another method is to insert a special nut 10 of the support 9 into the cable 3, pass it through the round hole 11 of the panel surface 2, and then pass it through the cylindrical support 9 from the outside as shown in FIG. 5(a). Tighten nut 10. Then, Figure 5
As shown in (b), the cable 3 is held on the panel surface 2. (The positions of the support 9 and the nut 10 may be reversed.) However, in the cable holding structure having such a configuration, the work must be done from inside and outside the box. Also, pass a support/nut through each cable and secure it using a tool. As described above, there was a problem of poor workability. Further, since the support is cylindrical in shape, there is a problem in that it is difficult to apply a cable with a connector whose terminal is processed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cable holding device which can be used even with a cable with a terminal-treated connector and which is capable of holding the cable, attaching it to a panel, and fixing it with a single touch, and which has good workability. [Structure of the invention]

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned objects, the present invention provides a structure in which a concavo-convex portion corresponding to the cross-sectional shape of the cable to be connected inside the box is formed on the surface on the cable holding side, so that the cable can be passed through the box. A convex part is formed on the bottom surface of the box to be inserted into a hole in a panel surface of a part of the box, and a first cable holder that can be fixed to this panel surface, and a concave and convex part corresponding to the cross-sectional shape of this cable are used to hold the cable. A convex portion formed on a side surface and inserted into a hole in a panel surface of a part of the box through which the cable is passed is formed on the lower surface, and a second cable holder that can be fixed to this panel surface; The cable holding body and the second cable holding body each include a connecting part that slides to connect the cable holding side surface of the second cable holding body to the cable holding side surface of the first cable holding body. It is characterized by holding the cable by sandwiching the cable from both sides and fixing it to the panel.

[0007]

[Function] In a device configured in this way, the uneven portion formed on the cable holding side surface of the first cable holder and the uneven portion formed on the cable holding side surface of the second cable holder. pinch the cable from both sides. Furthermore, the cable holding side surface of the first cable holding body and the cable holding side surface of the second cable holding body are connected by sliding. Drop the protrusions formed on the lower surfaces of the connected first and second holders into the holes in the panel surface of the box,
Fix it to the panel surface.
