In more detail, the cable fixing device 100 may include three support parts each extending perpendicular to the bottom surface of the body part 11 on the left and right sides of the body part 11. Here, the six support parts respectively provided on the left and right sides may be disposed at positions spaced apart from each other by a predetermined distance from each side. For example, the support parts disposed on the left side may be provided at the upper left side, the left middle side, and the lower left side, respectively, and the two support grooves may be provided at the left side by providing the respective support parts spaced apart from each other at regular intervals. Similarly, the support parts disposed on the right side may also be provided at the upper right side, the right middle side, and the lower right side, and two support grooves may be provided. In the cable fixing device 100 having such a structure, the supporting grooves for adjusting the flow of soldering are arranged in more various manners, thereby stably inducing the soldering shape between the cable 300 and the cable fixing device 100 during the soldering process. can do. Meanwhile, when the cable fixing device 100 is provided in a form including six support parts, the insertion holes 233 of the substrate 200 may also be provided with six insertion holes to correspond to the shape of the support parts. The cable fixing device 100 having the structure as described above is provided with a plurality of supporting grooves so that soldering is performed while soldering is performed after the cable 300 is seated on the cable fixing device 100. Better penetration into the soldering process improves the yield.

As such, the cable anchoring device 100 according to the embodiment of the present invention may be provided with various forms and supports having various numbers, and the shape of the substrate may be changed accordingly.

On the other hand, it has been described with respect to the preferred embodiments of the present invention through the specification and drawings, although specific terms are used, this is only used in a general sense to easily explain the technical details of the present invention and to help the understanding of the invention. It is not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical spirit of the present invention can be carried out even in the embodiments disclosed herein.
