In adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are assigned to the same components as much as possible even though they are shown in different drawings. In addition, in describing an embodiment of the present invention, if it is determined that the detailed description of the related known configuration or function is to interfere with the understanding of the embodiment of the present invention, the detailed description thereof will be omitted.

In addition, in explaining the component of the Example of this invention, terms, such as 1st, 2nd, A, B, (a), (b), can be used. These terms are only for distinguishing the components from other components, and the nature, order or order of the components are not limited by the terms. If a component is described as being "connected", "coupled" or "connected" to another component, that component may be directly connected or connected to that other component, but between components It will be understood that may be "connected", "coupled" or "connected".

Hereinafter, the structure of the present invention will be described with reference to the drawings.

The first body 101 and the second body 102 of the cable holder (H) is extended so that the cable (C) can be inserted in a straight line, connected to each other is integrally injection molded. The present invention discloses an embodiment in which two hexahedral shapes are integrally formed, but is not limited thereto. For example, the first body 101 and the second body 102 may be injection molded separately, and the first body 101 and the second body 102 may be connected together using separate fixing means.

The first body 101 and the second body 102 are formed with a first through hole 111 and a second through hole 112 into which the cable C is inserted. Before the first body 101 and the second body 102 are assembled with the cable C, the first through hole 111 and the second through hole 112 pass through the cable C in a straight line. It is formed side by side so that it can be.

The cable C is inserted into the first through hole 111 or the second through hole 112 so that the cable C passes through the first through hole 111 and the second through hole 112. Withdrawn and extended. In this case, since the first through hole 111 and the second through hole 112 are formed in a straight line, the first through hole 111 does not have to pass through the through hole in a bent state.

At this time, it is preferable that the through-hole formed with the cable hanger 140 to be described later is formed larger than the relative through-hole. This is because the cable hanger 140 serves to fix the connector C 'connected to the cable C, because a part of the connector C' is inserted into the through hole.

In addition, the shape of the first through hole 111 and the second through hole 112 is preferably polygonal. If the through hole is polygonal because the outer surface of the cable C is cylindrical, the cable C and the first body may be externally circumscribed to the cable C, the first body 101 and the second body 102. A gap is formed between the first body 101 and the second body 102. During the molding process, the liquid resin flows through the gap to increase the fixing force between the first body 101 and the second body 102 and the cable C.

A hinge portion 120 is formed at a portion where the first body 101 and the second body 102 are connected to each other, and is precisely formed on the bottom surface between the first body 101 and the second body 102. Hinge portion 120 is formed. The hinge portion 120 is integrally formed with the first body 101 and the second body 102. The hinge portion 120 is formed to be thinner than the thickness of the bottom surface of the first body 101 and the second body 102 is configured to bend easily. However, the present invention is not limited thereto, and the first body 101, the second body 102, and the hinge portion 120 may be formed separately and assembled. The hinge part 120 has a rotation axis P in a direction perpendicular to a direction in which the first through hole 111 and the second through hole 112 extend, and the first axis is based on the rotation axis P. The body 101 or the second body 102 may be bent in a relative rotation.

In addition, a plurality of elastic slits 125 are formed on both bottoms of the first body 101 and the second body 102 so as to be spaced apart from each other in a slit form on both sides of the hinge 120. When the elastic slit 125 is formed, the repulsive force by the material of the resin itself is reduced to help the hinge portion 120 rotate better.

In addition, the elastic deformation of the hinge portion 120 is most affected by the fatigue load generated while the hinge portion 120 is repeatedly deformed during the relative rotation of the first body 101 and the second body 102. A large portion is deformed, and if severe, cracks or whitening occur, and the elastic slit 125 prevents this problem.

When the first body 101 or the second body 102 is rotated and bent, the interference body to solve the problem that the first body 101 and the second body 102 is not bent due to interference with each other Skin 122 is formed. The interference avoiding portion 122 is composed of side interference avoiding skin 123 and the upper surface interference avoiding skin 124.

The side interference avoiding skin 123 is formed to be symmetrically inclined by a predetermined angle from the rotation axis P of the hinge portion 120. It is inclined to form a groove from a bottom of the first body 101 and the second body 102 to a predetermined height of both side walls. The degree of bending the first body 101 and the second body 102 can be adjusted according to the angle at which the lateral interference skin 123 is inclined.

The empty space created by the lateral interference skin 123 gives room to allow the first body 101 or the second body 102 to be bent and the first body 101 and the second body ( When the first body 101 or the second body 102 is rotated relative to each other, the side interference avoiding skin 123 is engaged with each other and the cable holder H is bent. The first body 101 and the second body 102 may be rotated relative to each other by a necessary angle even if the side interference skin 123 is not substantially engaged or closely contacted.

The upper surface interference avoiding skin 124 is formed by stepping a portion of the upper surface of the first body 101 and the second body 102 at a predetermined interval from each other. The upper surface of the first body 101 and the second body 102 is opened on the basis of the rotation axis P of the hinge part 120 by the upper surface interference avoiding skin 124. Accordingly, even when the first body 101 and the second body 102 are rotated relative to each other, the upper surfaces of the first body 101 and the second body 102 are bent without interference.

On the other hand, as shown in Figure 5, if the hinge portion 120 is formed to extend long, since the first body 101 and the second body 102 does not interfere with each other, the interference avoiding portion 122 is It may not be formed.

Fastening means 130 are formed on the upper surfaces of the first body 101 and the second body 102, specifically, the portions where the upper surface interference avoiding skin 124 is not formed. The fastening means 130 includes a fastening hook 131 and a fastening protrusion 132. Fastening hooks 131 and fastening protrusions 132 are formed on upper surfaces of the first body 101 and the second body 102, respectively.

However, it is not always necessary to form the fastening hook 131 on the first body 101 and the fastening protrusion 132 on the second body 102. A fastening protrusion 132 may be formed on the first body 101, and a fastening hook 131 may be formed on the second body 102.

The fastening hook 131 and the fastening protrusion 132 are formed on the first body 101 and the second body 102, respectively, and the fastening hook 131 is formed in an annular shape with a center formed therein. It is fitted to surround the fastening protrusion 132 is coupled. When the fastening hook 131 and the fastening protrusion 132 are coupled to each other, the first body 101 and the second body 102 maintain the bent state without being unfolded again by the restoring force.

At this time, the fastening protrusion 132 is formed with a projection slope surface 133 in the direction in which the upper surface interference avoiding skin 124 is formed. The protrusion inclined surface 133 prevents the problem that the fastening protrusion 132 does not completely bend due to interference with the counterpart body or the fastening hook 131 when the counterpart body rotates and approaches.

Similarly, the fastening hook 131 also has a hook inclined surface 133 ′ in the direction in which the upper surface interference avoiding skin 124 is formed. The hook inclined surface 133 ′ prevents the fastening hook 131 from interfering with the counterpart body or the fastening protrusion 132 when the counterpart body rotates to prevent the bending from being completely made.

In this case, the relative body may be defined as a body other than the reference body, and specifically, as follows.

The relative body of the first body 101 is the second body 102 and, on the contrary, the relative body of the second body 102 becomes the first body 101. In addition, the relative body of the body having the fastening hook 131 is the body having the fastening protrusion 132, on the contrary, the relative body of the body having the fastening protrusion 132 is a body having the fastening hook 131. .

The cable (C) is inserted into the inlet of the first through hole 111 or the second through hole 112, the cable (C) is inserted into the inlet of the end of the cable (C) is complete insertion The cable hanger 140 holding the connector C 'is formed.

The cable hanger 140 is formed with a hook-shaped protrusion 143 in the inward direction of the through hole. The connector C 'is fixed to the protrusion 143 so that the connector C' does not escape from the through hole. Grooves may be formed in the protrusion 143 of the cable hanger 140 to correspond to the shape of the connector C '. In the present embodiment, a circular groove is formed in the protrusion 143 of the cable hanger 140 to correspond to the shape of the circular connector C '.

The cable hanger 140 is to be provided with a fixing force capable of sufficiently fixing the connector (C '), the number formed is not limited. In this embodiment, two pairs of the cable hangers 140 are formed to face each other on the first body 101 or the second body 102 having a rectangular parallelepiped shape.

 The through-holes in which the cable hanger 140 is formed should be fixed to span the cable hanger 140 by inserting a part of the connector C 'coupled to the front end of the cable C as well as the cable C. Therefore, the through hole in which the cable hanger 140 is formed may be formed larger than the size of the relative through hole.

For example, if the cable hanger 140 is formed in the first through hole 111, the cable C is inserted through the first through hole 111, the front end of the cable (C) The connector (C ') is to be fixed in combination with the cable hanger 140.

The inlet inclined surface 141 is formed on the upper surface of the cable hanger 140 to be inclined in a direction to gradually reduce the size of the through hole. The structure of the inlet slope 141 facilitates the insertion of the cable C, and when the part of the connector C 'is inserted, helps the cable hanger 140 to elastically deform smoothly.

Slits 142 are formed at both sides of the cable hanger 140. The slit 142 serves to increase the elastic force by protruding the cable hanger 140 in the form of a cantilever.

Accordingly, the slit 142 is formed to increase the elastic force of the cable hanger 140, and the cable hanger 140 is softly elastically deformed by the inlet inclined surface 141, so the fastening feeling with the connector C '. This increases.

In the drawing of this embodiment is disclosed that the width of the slit 142 is extended to meet the slit on the other side only the cable hanger 140 protrudes.

The first body 101 and the second body 102 are formed with a resin inlet 150 having both sidewalls open. Specifically, the inclined portion of the side interference avoiding skin 123 is an open part meeting to be bent with the extension line of the step surface of the upper surface interference avoiding skin 124. The resin inlet unit 150 allows the liquid resin for molding to flow into the cable holder H, which is bent and fixed to the cable C.

The reason why the above-described through hole is polygonal also plays the same role as the resin inflow unit 150. The liquid resin flows well through the gap formed between the rounded outer surface of the cable (C) and the polygonal through hole contacting the outer surface of the cable (C).

Next, a process of bending and inserting the cable C into the cable holder H will be described with reference to the drawings.

The cable C is connected to the end of the connector C 'so that the connector C' is connected to the first through hole 111 or the second through hole 112. Should be inserted

In the embodiment, the cable C passes through the first through hole 111 first, but the cable C passes through either the first through hole 111 or the second through hole 112 first. Does not matter. However, it is preferable that the through hole through which the cable C passes first is larger than the relative through hole and a cable hanger 140 is further formed. In this embodiment, the size of the first through hole 111 is larger than the size of the second through hole 112.

When the opposite end where the connector C 'of the cable C is formed is inserted through the inlet of the first through hole 111, the cable C passes through the second through hole 112 sequentially. The sufficiently inserted cable C passes through the first through hole 111 and the second through hole 112 until the connector C 'meets the first body 101. A part of the connector C 'is inserted into the first through hole 111 and fixed over the cable hanger 140.

When the connector C 'is fixed over the cable hanger 140 formed on the first body 101, the hinge portion 120 is bent. The hinge part 120 has a rotation axis P in a direction perpendicular to a direction in which the first through hole 111 and the second through hole 112 extend, and the first axis is based on the rotation axis P. The body 101 or the second body 102 may be bent in a relative rotation. The hinge portion 120 is formed to be thinner than the thickness of the bottom surface between the first body 101 and the second body 102 is configured to facilitate bending.

When the hinge portion 120 rotates based on the rotation axis P, the first body 101 or the second body 102 rotates, and the first through hole 111 and the second through hole 112 are rotated. The cable C inserted in the c) is also bent together.

In this case, the interference avoiding part 122 is formed to prevent the first body 101 and the second body 102 from interfering with each other.

The empty space created by the interference avoiding unit 122 allows a space to be bent by the first body 101 or the second body 102 so that the first body 101 and the second body 102 can be bent. ) To prevent interference with each other.

The bent first body 101 and the second body 102 are unfolded again by the restoring force of the hinge portion 120 and the restoring force of the bent cable C. The first body In order to prevent the 101 and the second body 102 from being unfolded, fastening means 130 are formed on the upper surfaces of the first body 101 and the second body 102, respectively.

When the relative rotation of the first body 101 and the second body 102 is completed, the fastening hook 131 and the fastening protrusion 132 formed on the first body 101 and the second body 102, respectively, In combination, it repels the restoring force and maintains the bent state.
