Description

Cable holder {CABLE HOLDER}

The present invention relates to a cable holder, and more specifically, to a cable holder that maintains a cable extending in a straight line in a bent state.

In general, coaxial cables wrap the central conductor (copper core wire) in the center with an insulator such as polyethylene to prevent signal disturbance, wrap it again with a net-shaped outer metal wire to shield adjacent lines, and then protect the outer surface of the coaxial cable. It is composed of clothing. Such a coaxial cable is one of the inductive transmission media and is widely used as a physical data transmission path between a receiver and a transmitter in a data transmission system.

In addition, when such a coaxial cable is used as a transmission medium such as cable TV broadcasting, a divider for equally distributing input signals into two or more is generally required. used

On the other hand, the conventional coaxial cable connector is composed of a linear housing in which a central terminal portion coated with an insulating member is installed, and a signal pin extending from the central terminal portion is provided at the upper end to connect to a terminal such as a distributor, which is an electrical device. , At the lower end, a central terminal connecting member is installed so as to be electrically connected to the central conductor of the coaxial cable, so that the coaxial cable is coupled to the distributor.

However, the conventional coaxial cable connector is folded in a right angle direction when connecting the coaxial cable to the distributor, but it takes a long time to insert the cable into the already bent holder when arranging the coaxial cable to be folded. In addition, since an additional holder is required to fix the coaxial cable connector, the number of parts is increased and workability is poor.

In order to solve the above problem, an object of the present invention is to simplify the process of inserting and bending a cable into a holder, and to provide a cable holder in which the cable is also bent during the process of assembling the holder.

The present invention relates to a first body having a first through hole into which a cable is inserted, a second body having a second through hole through which the cable is inserted, and a hinge portion rotatably connecting the first body and the second body. And, including a fastening means for maintaining the first body and the second body in a rotated state, and when the first body or the second body is relatively rotated and fixed by the fastening means, the first through hole and the second body The two through-holes extend in different directions, and the cable extending in a straight line passing through the first through-hole and the second through-hole is bent.

The fastening means is made of a ring-shaped fastening hook and a fastening protrusion that is caught on the fastening hook, and is formed on the outer surfaces of the first body and the second body, respectively, and when the fastening hook and the fastening protrusion are combined, the first body and The second body is maintained in a rotated state.

Interference avoidance skins are formed on the first body and the second body so as not to interfere with each other when the first body or the second body rotates, and the interference avoidance skin is partially opened on the upper surfaces of the first body and the second body. It is composed of a top surface interference avoiding skin stepped as much as possible and a side interference avoiding skin inclined symmetrically from the rotational axis of the hinge part.

A hook inclined surface is further formed on the fastening hanger in a direction in which the upper surface interference avoiding skin is formed, and a hook inclined surface is further formed on the fastening protrusion in a direction in which the upper surface interference avoiding skin is formed.

Side surfaces of the first body and the second body are opened to form a resin inlet.

The through hole has a polygonal shape in close contact with the outer surface of the cable.

The hinge part is formed thinner than the thickness of the bottom surface of the first body and the second body to be flexible.

A cable hanger for fixing the cable is further formed at an inlet of the first through hole or the second through hole.

The size of the through hole of the first body or the second body in which the cable hanger is formed is larger than the size of the through hole of the other body.

The cable hanger is formed integrally with the first body or the second body, and slits are formed on both sides thereof to have elasticity.

An inlet inclined surface is further formed on the upper surface of the cable hanger so as to be inclined in a direction of gradually reducing the size of the through hole.

The first body, the second body, the hinge part and the fastening means are integrally injection-molded.

The cable holder according to the present invention has the following effects.

First, in the present invention, after inserting a cable into a through hole formed in a holder body extending in a straight line, when the holder body is bent, the cable is also bent, so the process of inserting the cable into the holder body is simplified and the manufacturing process is simplified.

Second, in the present invention, since a cable hanger is formed at the entrance of the through hole formed in the holder body to fix the connector connected to the cable, an additional holder for fixing the connector is not required, reducing the number of parts and man-hours.

Third, in the holder body of the present invention, the resin inlet is formed to be open, and the through hole is formed wider than the outer surface of the cable. Therefore, in the molding process, since the liquid resin flows well between the cable and the holder body through the resin inlet and the gap between the cable and the through hole, it is economical because the defect rate is reduced.

Hereinafter, some embodiments of the present invention will be described in detail through exemplary drawings. In adding reference numerals to components of each drawing, it should be noted that the same components have the same numerals as much as possible even if they are displayed on different drawings. In addition, in describing an embodiment of the present invention, if it is determined that a detailed description of a related known configuration or function hinders understanding of the embodiment of the present invention, the detailed description will be omitted.

Also, terms such as first, second, A, B, (a), and (b) may be used in describing components of an embodiment of the present invention. These terms are only used to distinguish the component from other components, and the nature, order, or order of the corresponding component is not limited by the term. When an element is described as being “connected,” “coupled to,” or “connected” to another element, that element may be directly connected or connected to the other element, but there may be another element between the elements. It should be understood that may be "connected", "coupled" or "connected".

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

The first body 101 and the second body 102 of the cable holder H are extended so that the cable C can be inserted in a straight line, and are connected to each other and integrally injection molded. Although the present invention discloses an embodiment in which two hexahedral shapes are integrally formed, it is needless to say that it 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 as one using a separate fixing means.

A first through hole 111 and a second through hole 112 into which the cable C is inserted are formed in the first body 101 and the second body 102 . Before the first body 101 and the second body 102 are assembled with the cable C, the cable C passes through the first through hole 111 and the second through hole 112 in a straight line. They are formed side by side in a row to be able to do it.

The cable C is inserted into the entrance of 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. drawn out and extended At this time, since the first through hole 111 and the second through hole 112 are formed in a straight line, the cable C does not have to pass through the through hole in a bent state.

At this time, it is preferable that the through hole in which the cable hanger 140 to be described later is formed is larger than the corresponding through hole. This is because the cable hanger 140 serves to fix the connector C' connected to the cable C, and at this time, 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 a polygonal shape. Since the outer surface of the cable C has a cylindrical shape, if the through hole has a polygonal shape, it circumscribes the cable C, the first body 101, and the second body 102, while the cable C and the second body 102 are circumscribed. A gap is formed between the first body 101 and the second body 102. During the subsequent molding process, liquid resin flows in through the gap to increase the fixing force between the first body 101 and the second body 102 and the cable C.

A hinge part 120 is formed at a portion where the first body 101 and the second body 102 are connected, precisely on the bottom surface between the first body 101 and the second body 102 A hinge portion 120 is formed. The hinge part 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 surfaces of the first body 101 and the second body 102 so as to be easily bent. However, it is not limited thereto, and it is also possible that the first body 101, the second body 102, and the hinge part 120 are separately formed and assembled. The hinge part 120 has a rotation axis P in a direction perpendicular to the direction in which the first through hole 111 and the second through hole 112 extend, and the first The body 101 or the second body 102 may be bent by relative rotation.

In addition, a plurality of elastic slits 125 are formed in a slit shape on both sides of the bottom surfaces of the first body 101 and the second body 102 with respect to the hinge portion 120 and are spaced apart from each other. When the elastic slit 125 is formed, the repulsive force caused by the material of the resin itself is reduced to help the hinge part 120 rotate better.

In addition, the elastic deformation of the hinge part 120 is most A lot of parts are deformed, and cracks or whitening occur in severe cases, and the elastic slit 125 prevents this problem.

When the first body 101 or the second body 102 is rotated and bent, the first body 101 and the second body 102 interfere with each other to solve the problem of not being bent. Skin 122 is formed. The interference avoiding skin 122 is composed of a side interference avoiding skin 123 and a top interference avoiding skin 124.

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

The empty space created by the side interference avoiding skin 123 gives a margin of space so that the first body 101 or the second body 102 can be bent, so that the first body 101 and the second body ( 102) from causing interference with each other, and when the first body 101 or the second body 102 rotates relative to each other, the side interference avoiding skins 123 are engaged with each other and the cable holder H is bent. It is only necessary that the first body 101 and the second body 102 can rotate relative to each other by a necessary angle even if the side interference avoiding skin 123 is not substantially engaged or brought into close contact with each other.

The upper surface interference avoiding skin 124 is formed so that portions of the upper surfaces of the first body 101 and the second body 102 are stepped apart from each other at regular intervals. The upper surfaces of the first body 101 and the second body 102 are opened with respect to the rotation axis P of the hinge part 120 by the upper surface interference avoiding skin 124 . Therefore, even when the first body 101 and the second body 102 rotate relative to each other, the respective upper surfaces are bent without interference.

On the other hand, as shown in FIG. 5, when the hinge part 120 is formed to extend long, the first body 101 and the second body 102 do not interfere with each other, so that the interference avoidance part 122 may not be formed.

Fastening means 130 are formed on the upper surfaces of the first body 101 and the second body 102, specifically, on the portion where the upper surface interference avoiding skin 124 is not formed. The fastening means 130 is composed of a fastening hook 131 and a fastening protrusion 132. A fastening hook 131 and a fastening protrusion 132 are formed on the 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 a ring shape with a hole in the middle, It is fitted and coupled so as to surround the fastening protrusion 132 . When the fastening hanger 131 and the fastening protrusion 132 are coupled, the first body 101 and the second body 102 maintain a bent state without being straightened again by a restoring force.

At this time, the fastening protrusion 132 has a protrusion inclined surface 133 formed in the direction in which the upper surface interference avoiding skin 124 is formed. The protruding inclined surface 133 prevents a problem in which bending is not completely achieved due to interference of the fastening protrusion 132 with the mating body or the fastening hanger 131 when the mating body rotates and approaches.

Similarly, the fastening hook 131 also has a hook inclined surface 133' formed in the direction in which the upper surface interference avoiding skin 124 is formed. The hook inclined surface 133' prevents the hooking hook 131 from interfering with the mating body or the fastening protrusion 132 when the mating body rotates and approaches, preventing the bending from occurring completely.

At this time, the relative body can be defined as a body that is not a standard body, and a specific example is as follows.

The counterpart body of the first body 101 is the second body 102, and conversely, the counterpart body of the second body 102 becomes the first body 101. In addition, the body having the fastening hook 131 has a body having the fastening protrusion 132, and conversely, the body having the fastening protrusion 132 and the body having the opposite body has the fastening hook 131. .

The cable (C) is inserted into the entrance of the first through hole 111 or the second through hole 112, and the cable (C) is inserted into the entrance connected to the tip of the cable (C) where the insertion is completed. A cable hanger 140 holding the connector C' is formed.

The cable hanger 140 is formed with a protrusion 143 in the form of a hook toward the inside of the through hole. The protruding portion 143 spans one side of the connector C' and is fixed so that the connector C' does not escape from the through hole. A groove may be formed in the protrusion 143 of the cable hanger 140 to correspond to the shape of the connector C'. In this 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 only needs to have a fixing force capable of sufficiently fixing the connector (C'), and the number of cable hangers 140 is not limited. In this embodiment, two pairs of cable hangers 140 are formed to face each other in the first body 101 or the second body 102 having a rectangular parallelepiped shape.

In the through hole where the cable hanger 140 is formed, not only the cable C but also a part of the connector C′ coupled to the tip of the cable C must be inserted and fixed across the cable hanger 140. Therefore, it is preferable that the size of the through hole in which the cable hanger 140 is formed is larger than the size of the corresponding 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, and the front end of the cable C The connector (C ') in is fixed by being combined with the cable hanger (140).

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

Slits 142 are formed on both sides of the cable hanger 140. The slit 142 serves to increase elasticity by protruding the cable hanger 140 in a cantilever shape.

Therefore, since the slit 142 is formed, the elastic force of the cable hanger 140 increases, and the cable hanger 140 is softly and elastically deformed by the inlet inclined surface 141, so that the connection feeling with the connector C' is increased. this increases

In the drawing of this embodiment, the width of the slit 142 is expanded to meet the slit on the other side, and only the cable hanger 140 protrudes.

The first body 101 and the second body 102 are formed with resin inlet portions 150 with both side walls open. Specifically, the inclined portion of the side interference avoiding skin 123 is an open portion that meets the extension line of the stepped surface of the upper surface interference avoiding skin 124 so as to be bent. The resin inlet 150 allows the liquid resin for molding to flow well into the cable holder H in which the cable C is bent and fixed.

The reason why the above-described through hole has a polygonal shape also serves the same role as the resin inlet 150. It helps the liquid resin to flow well through the gap formed between the cable (C) with a round outer surface and the polygonal through hole in contact with the outer surface of the cable (C).

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

The cable (C) has a connector (C') connected to its tip, so in order to insert it into the first through hole 111 or the second through hole 112, the opposite side of the end where the connector (C') is formed is first should be inserted

The first body 101 and the second body 102 are arranged side by side so that the cable C can be inserted in an extended state in a straight line. In other words, the first through hole 111 and the second through hole 112 formed in the first body 101 and the second body 102 are disposed side by side so as to be connected.

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 first passes has a larger size than the corresponding through hole and more cable hangers 140 are 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 of the cable C where the connector C' is formed is inserted through the entrance of the first through hole 111, it sequentially passes through the second through hole 112. 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 portion of the connector (C') is inserted into the first through hole 111 and is fixed across the cable hanger 140 .

When the connector (C') is fixed across 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 the direction in which the first through hole 111 and the second through hole 112 extend, and the first The body 101 or the second body 102 can be bent by relative rotation. The hinge part 120 is formed to be thinner than the thickness of the bottom surface between the first body 101 and the second body 102 so as to be easily bent.

When the hinge part 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 ), the cable (C) inserted into it is also bent together.

At this time, an interference avoidance skin 122 is formed to prevent the first body 101 and the second body 102 from being bent due to interference with each other.

The empty space created by the interference avoiding skin 122 gives a margin of space so that the first body 101 or the second body 102 can be bent, so that the first body 101 and the second body 102 ) to prevent them from interfering with each other.

The bent first body 101 and the second body 102 are stretched again by the restoring force of the hinge part 120 and the restoring force of the bent cable C, and the first body ( 101) and the second body 102, fastening means 130 are formed on the upper surfaces of the first body 101 and the second body 102, respectively, in order to prevent them from unfolding again.

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 respectively formed on the first body 101 and the second body 102 Combined, it resists the restoring force and maintains the bent state.

When the cable (C) is completely bent by the cable holder (H), insert injection molding is performed so that the connector (C') connected to the tip of the cable (C) protrudes.
