The upper section and the lower section of the second opening 124 may have the same cross-sectional area. In addition, the upper section and the lower section of the second opening 124 may have different cross-sectional areas, and in this case, the upper section of the second opening 124 may have a larger section than the lower section.

On the lower case seating part 130, the above-described lower case 110, cable 1, and upper case 120 are sequentially stacked, and the lower case 110 may be coupled to be detachable from the upper case 120. . The lower case seating portion 130 may be formed in a plate shape as illustrated. Furthermore, the lower case seating portion 130 may be formed in a polygonal or circular pipe shape.

A slit 131 is formed on an upper portion of the lower case seating portion 130. The slit 131 may be formed to overlap the first opening 112 and the second opening 124 of the lower case 110 described above. The width of the slit 131 may be formed to be greater than or equal to the vertical distance of the first straight portion 112a and the second straight portion 112b forming the bottom of the first opening 112 overlapping the slit 131. Can be.

The insertion unit 140 includes a cylindrical body portion 141, a fixing portion 142 protruding in the axial direction at the bottom, and an assembly portion 143 assembled with the lever 150 at the top. The insertion unit 140 and the lever 150 are not limited in their material as long as they are rigid materials, but may preferably be formed of polyketone materials among engineering plastics. Accordingly, it is possible to reduce the cost consumed by the material, it is possible to reduce the weight and have sufficient rigidity.

The body portion 141 and the fixing portion 142 of the insertion unit 140 include a first opening 112 of the upper case 120, a second opening 124 of the lower case 110 and a lower case seating portion 130. ) Penetrates the slit 131 and is formed to be fastened to each other.

Furthermore, the assembly portion 143 may be formed so that the lever 150 can be assembled and detached. The assembly unit 143 is formed in a circular shape as shown in the figure, the lever 150 may be assembled. The assembly portion 143 may be seated on the flat portion 122 of the upper case 120.

In detail, the height at which the assembly portion 143 is seated on the flat portion 122 and protrudes may be formed smaller than the vertical distance from the protrusion 121 to the flat portion 122. Since the height of the assembly portion 143 is formed smaller than the height difference from the protrusion portion 122 to the flat portion 123, protrusion by the assembly portion 143 and the lever 150 can be minimized.

On the other hand, the cross section of the fixing portion 142 is provided with a fifth straight portion 142a and a sixth straight portion 142b facing each other, and the fifth straight portion 142a and the sixth straight portion 142b are fifth. It may be connected by the curved portion 142c and the sixth curved portion 142d.

The closed figure forming the cross section of the fixing part 142 has a different aspect ratio, and the vertical distance between the fifth straight part 142a and the sixth straight part 142b is the fifth curved part 142c and the sixth curved part ( 142d) may be shorter than the vertical distance between. In addition, the vertical distance between the fifth curved portion 142c and the sixth curved portion 142d may be greater than the width of the slit 131.

Accordingly, the body portion 141 and the fixing portion 142 of the insertion unit 140 may be inserted into the first opening 112, the second opening 124 and the slit 131 and rotated at a predetermined angle. The predetermined angle may be preferably 90 degrees.

The lower case 110 is rotated by a predetermined angle after insertion due to a difference in the vertical distance between the fifth curved portion 142c and the sixth curved portion 142d of the fixing portion 142 and the width of the slit 131. The upper case 120 and the lower case seating portion 130 may be fixed.

Hereinafter, the fastening of the cable fixing device 100 by the insertion unit 140 and the lever 150 will be described in detail.

First, the lower case 110 is stacked on the lower case seating portion 130 and the cable 1 is disposed on the lower contact surface 111. Next, the upper case 120 is stacked on the lower case 110 to form a third opening 160 accommodating the cable 1. Subsequently, the lever 150 is assembled to the assembly portion 143 of the insertion unit 140, the second opening 124 of the upper case 120, the first opening 112 and the slit of the lower case 110 ( The body portion 141 and the fixing portion 142 of the insertion unit 140 are inserted to penetrate the 131). When the fixing part 142 is inserted into the slit 131, the lever 150 may contact the flat part 123. By rotating the lever 150 contacting the flat portion 123 in a predetermined angle direction, the insertion unit 140 can rotate a predetermined angle. That is, the vertical distance between the fifth curved portion 142c and the sixth curved portion 142d of the fixing portion 142 and the width of the slit 131 may be wider to be physically fixed. Furthermore, the lever 150 is pressed downward to press it. That is, since the lever 150 is rotated and lowered in the direction in which it is pressed, it can be compressed by the upper case 120 and fixed by the insertion unit 140. In addition, the lowered lever 150 may be inserted into the recess 125 to be concealed.

3 to 5 is a view showing the operating relationship of the cable fixing device 100 shown in Figure 1 in various directions. 3 to 5(a), the lever 150 of the cable fixing device 100 is lowered and compressed to show that the cable 1 is fastened. Meanwhile, referring to FIGS. 3 to 5(b), the lever 150 of the cable fixing device 100 is shown in an open state in which the lever 150 is not compressed.

The cable fixing device 100 of the present invention can easily fix the cable 1 in a one-touch manner using the lever 150. This has the effect of reducing the time and cost of fixing the cable.

In addition, when the lever 150 is pressed downward to insert the lever into the concave portion 125, the height of the assembly portion 143 is smaller than the height difference from the protrusion 122 to the flat portion 123. Therefore, the protrusion by the assembly part 143 and the lever 150 can be minimized. In addition, when the cable fixing device 100 is fastened, the lever 150 is concealed by the concave portion 125, and when the worker proceeds with additional work after fixing the cable, the lever 150 is accidentally pressed on the work. This is released to prevent the fastening of the cable fixing device 100 from being released.

In addition, in other embodiments described below, the same or similar reference numerals are assigned to the same or similar configurations as the previous examples, and the description is replaced with the first description.

Further, it is formed of an insertion unit 240 and a lever 250 extending in one direction to penetrate the lower case 210, the upper case 220, and the lower case seating portion 230. The lever 250 is assembled to the top of the insertion unit 240 and is formed to rotate. The lever 250 is lowered under pressure to compress the upper case 220. Accordingly, the upper case 220, the lower case 210, and the lower case seating portion 230 may be fixed by the insertion unit 240 and the lever 250.

The concave portion 225 of the cable fixing device 200 may be formed by being recessed in a direction different from that of FIGS. 1 to 5 described above. In detail, the recess 1225 may be recessed in the direction in which the second opening 224 is disposed in front of the cable fixing device 200.

Accordingly, when the cable fixing device 200 is fastened, the lever 250 is concealed by the concave portion 225 disposed on the front side, so that a separate device is disposed on the side, or the cable fixing device 200 is spaced apart from each other. Even when they are arranged side by side, interference with each other can be minimized when the lever 250 is pressed.

It will be apparent to those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit and essential features of the invention.
