And, the end of the adjustment clamp 520, 520 'is provided with a screw block 550 to which the setting bolts 540, 540' are coupled.

Hooks for guiding the cable that is joined or introduced with the cable entry clamp under such a basic configuration (fixed type (as shown in Korean Patent Publication No. 1992-0009867 "wall terminal box mounting stand") or variable type (Korean Utility Model Publication) Publication No. 93-7571, "forms shown in the improved terminal box and cable entry wall", etc.), and an auxiliary plate for fixing the terminal box {Korean Patent Publication No. 1992-0009867 "Wall terminal box mounting stand" Etc.}, the Republic of Korea Patent Publication No. 195-0001118 "Technical configuration for the coupling of the setting bolts (540, 540 ') shown in the" clamping device of the attachment "and the like can be further configured.

On the other hand, the cable entry walls according to the prior art (500, 500 ') is difficult to mass production due to the difficulty of manufacturing, there is a problem that can not maintain a stable and uniform quality. That is, the cable entry wall (500, 500 ') according to the prior art is formed by cutting the horizontal bar (512, 522) square bar, the vertical parts (514, 524) by cutting the angle' C ' Welding {cable entry wall 500 shown in FIG. 1 is a form in which the channel of the 'c' angle is directed outward, and cable entry wall 500 'shown in FIG. 2 is the channel of the' c 'angle. It is made to face outward}}. Therefore, since a series of product manufacturing processes such as cutting and welding of rectangular bars and angles are made by hand, mass production is difficult and stable and uniform quality due to machining error and product deformation generated in each process. You can't keep it. In particular, since the horizontal portions 512 and 522 and the vertical portions 514 and 524 are integrated by welding, a difference occurs in the quality of the product according to the welding proficiency, which causes a defect in the product due to poor welding.

Referring to Figures 5 to 7, looking at the manufacturing method of the cable entry wall iron according to a preferred embodiment of the present invention, first, as shown in Figure 5, to form a fixed clamp 20 and the adjustment clamp 20 ' In order to prepare each of the raw materials (20a, 20a ') (S1). Each raw material 20a, 20a 'prepared in this step S1 has a length L between both ends E1, E2 of which each horizontal portion 30 of the fixed clamp 20 and the adjustment clamp 20' is mounted. 30 ') and the same length as the entire length of the vertical portions 40, 40', and the width W between the upper and lower ends E3, E4 is each horizontal of the fixed clamp 20 and the adjustment clamp 20 '. It has the same length as the entire lengths of the upper surfaces 31 and 41 and both sides 32 and 42 of the sections 30 and 30 'and the vertical sections 40 and 40'. At this time, the length (L) and width (W) of each raw material (20a, 20a ') is a length including the curvature generated during bending. And, as in the preferred embodiment of the present invention, the horizontal portions 30, 30 'and the vertical portions 40, 40' of the fixed clamp 20 and the adjustment clamp 20 'face the lower surface 33, 43. Since it is possible to reinforce the strength of both sides (32, 42), the upper and lower ends (E3, E4) of each raw material (20a, 20a ') in the step (S1) of preparing each raw material (20a, 20a') The width W therebetween corresponds to the width of each of the horizontal portions 30, 30 ′ of the fixed clamp 20 and the adjustment clamp 20 ′ and the lower surfaces 33, 44 of the vertical portions 40, 40 ′. Make it longer. At this time, in the present embodiment, the lower surfaces 33 and 44 are formed on both sides 32 and 42 so as to be symmetrical with each other. However, if necessary, the lower surfaces 33 and 44 may be formed only on one side or long to one side. Thus, the step of preparing each raw material (20a, 20a ') may be made through a blanking process or a conventional cutting process of a wide plate (typically iron plate or stainless steel plate) press method.

Next, each of the raw materials 20a and 20a 'prepared as described above is formed by cutting the blanking surface 50a from the upper and lower ends E3 and E4 of the raw materials 20a and 20a' to be inwardly symmetrical through the blanking process of the press method. (S2). This step (S2) forms a blanking surface (50a) for the bending process consisting of the following, and forms a pinhole 62 to which the pin 122 for joining the adhesion plate 120 (see Fig. 4) is coupled later In addition, the setting bolts 100 (see FIG. 4) form the setting holes 60 to be inserted, and form the long holes 64 for coupling the additional mechanisms such as terminal boxes.

At this time, in the step (S2) to form the blanking surface 50a in the present embodiment, the blanking surface 50a is an outer end point formed by blanking from each side end (E1, E2) of each raw material (20a, 20a ') Lengths up to 51 correspond to the lower lengths L1 and L2 of the horizontal portions 30 and 30 'and the vertical portions 40 and 40' of the fixed clamp 20 and the adjustment clamp 20 '. To have. In addition, the inner end points 52 formed by blanking from each of the both ends E1 and E2 are formed with the horizontal portions 30 and 30 'and the vertical portions 40 and 40 of the fixed clamp 20 and the adjustment clamp 20'. It has a length corresponding to the upper length (L3, L4) of '). In particular, in the present embodiment in the step (S2) to form the blanking surface (50a), the blanking surface (50a) is an isosceles triangle with the inner end point 52 as the upper vertex, the outer end point 51 as both vertices of the lower side As formed by blanking in the shape of, as shown in FIG. 5, each of the horizontal portions 30, 30 ′ and the vertical portions 40, 40 ′ of the fixed clamp 20 and the adjustment clamp 20 ′ are in close contact with each other. The face 50 is formed. Of course, unlike the preferred embodiment of the present invention, the blanking surface 50a for bending the horizontal portions 30, 30 'and the vertical portions 40, 40' of the fixed clamp 20 and the adjustment clamp 20 '.
