  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of the cable protection cover 101. 2 is a top view of the cable protection cover 101, and FIG. 3 is a cross-sectional view of the cable protection cover 101 as viewed from the length direction of the X arrow in FIG. The cable protection cover 101 is formed so that a lid part 102 and a receiving part 103 are connected at both side edges and have a hollow portion 115. Further, the cable 130 can be disposed in the hollow portion 115. Further, as shown in FIGS. 2 and 3, auxiliary components 120 are installed between the lid component 102 and the cable 130 at appropriate intervals in the length direction of the cable protection cover 101.

  The lid component 102 includes a pair of fitting portions 104 and a lid portion 106, and the lid portion 106 is provided so as to connect between one fitting portion 104 and the other fitting portion 104. . The receiving part 103 includes a pair of fitted parts 105 and a bottom part 107, and the bottom part 107 is provided so as to connect between one fitted part 105 and the other fitted part 105. It has been. Further, the cover part 102 and the receiving part 103 are integrated to form the cable protection cover 101 by connecting the fitting part 104 and the fitted part 105. The lid part 102 and the receiving part 103 are manufactured by extrusion using a flexible material such as soft synthetic resin or rubber. In addition, since the number of parts is small and it is made of a flexible material such as soft synthetic resin or rubber, the sound at the time of deformation is reduced as compared with the conventional small parts connected in a chain shape.

  The fitted portion 105 formed over the entire length of the receiving component 103 has a cylindrical shape that is long in the length direction of the cable protection cover 101. On the other hand, the fitting portion 104 formed over the entire length of the lid component 102 has a C-shaped cross section perpendicular to the length direction, and the radius of the circle inside the C-shape is the radius of the fitted portion 105. It is formed in the same size as r1 or slightly smaller. Further, the fitting portion 104 and the fitted portion 105 are connected and fixed so that the fitted portion 105 is fitted into the fitting portion 104. Further, the radius r1 of the fitted portion 105 and the radius r2 of the C-shaped outer circle of the fitting portion 104, the thickness of the lid portion 106 and the bottom portion 107, and the elasticity of the lid component 102 and the receiving component 103 are hollow. Considering the elasticity, weight, number, etc. of the cables 130 arranged in the section 115, the cable protection cover 101 is designed to be held without buckling even if it is bent at least 180 degrees with a curvature under the usage environment. ing. In particular, the radius r1 of the fitted portion 105 is larger than the thickness of the lid portion 106 and the bottom portion 107.

  The lid portion 106 is formed between the one fitting portion 104 and the other fitting portion 104 so that the cross section draws an arc or a substantially rectangular shape. The lid portion 106 is formed with a plurality of vent holes 110 that are opened in a circular or elliptical shape along the length direction of the lid component 102. On the other hand, as shown in FIG. 4, the bottom 107 is formed between one fitted portion 105 and the other fitted portion 105 so that the cross section draws an arc or a substantially rectangular shape. Similarly, the bottom portion 107 is formed with a plurality of vent holes 114 that are open in a circular or elliptical shape along the length direction of the receiving component 103. Further, the hollow portion 115 and the outside air are exchanged through the vent holes 110 and 114. Thereby, the heat which generate | occur | produces with a cable can be discharge | released outside, and deterioration of a cable can be reduced. The vent holes 110 and 114 are formed by punching after the lid 106 and the bottom 107 are formed by extrusion.

  Further, as shown in FIG. 3, the lid portion 106 and the receiving portion 107 project into the hollow portion 115 so as to protrude in the length direction of the cable protection cover 101, and the protruding lid partition 111 and the receiving partition. 112 is formed. The lid partition 111 and the receiving partition 112 are formed in an appropriate number depending on the number of cables or the number of types of cables disposed in the hollow portion. The lid partition 111 and the receiving partition 112 suppress the movement of the cable in a plane perpendicular to the length of the cable so that the cables disposed in the hollow portion 115 are not entangled or stuck to each other. Further, the portion where the lid partition 111 and the receiving partition 112 are formed is a portion where the lid portion 106 and the receiving portion 107 are partially thickened, so that it is difficult to buckle when the cable protection cover 101 is bent. Furthermore, when the auxiliary part 120 is used as shown in FIG. 3, the lid partition 111 pushes the auxiliary part 120 toward the cable 130 side.

  FIG. 5A shows a top view of the auxiliary component 120. FIG. 5B is a side view of the auxiliary component 120 as viewed from the direction of the arrow Y in FIG. The auxiliary component 120 includes a pair of end column portions 21 and a bridge portion 22 connecting the end column portions 21. Further, the auxiliary component 120 is formed of a material that is the same as or harder than the lid component 102 and the receiving component 103. For example, it is made of aluminum or hard plastic.

  The end column portion 21 has a circular cross section, and has a certain length in the length direction of the cable protection cover 101. On the other hand, as shown in FIGS. 3 and 5B, the bridge portion 22 is formed with an auxiliary partition portion 23 that is a protrusion protruding from the bridge portion 22 toward the receiving component 103 side. The auxiliary partition 23 is formed so as to protrude toward the receiving component 103 at a position corresponding to the receiving partition 112 formed on the bottom 107 of the receiving component 103.

  Further, as shown in FIG. 3, the auxiliary component 120 is arranged inside the lid portion 106 so that the end column portion 21 is fitted in the concave portion between the lid portion 106 and the fitting portion 104, and the bridge portion 22 is provided with the lid partition. It is installed so as to pass between 111 and the cable 130. The bridge portion 22 is pushed in the direction of the cable 130 by the lid partition 111. For this reason, the auxiliary partition part 23 formed in the bridge part 22 restricts the movement of the cable 130 in a plane perpendicular to the length direction of the cable protection cover 101. Accordingly, the auxiliary component 120 adjusts the size of the space of the hollow portion 115 of the cable protection cover 101 so that the cable 130 is less likely to be entangled or twisted.

  As described above, the cable protection cover 101 of the present invention is composed of two parts, the lid part 102 and the receiving part 103, so that it can be assembled rather than combining parts made up of many parts as in the conventional example. Simple. Moreover, since the number of parts is small, there is no cost.

  In addition, since the cable protection cover 101 hardly bends at the place where the auxiliary component 120 is disposed, a plurality of the auxiliary components 120 are disposed at a constant interval, so that the cable protection cover 101 is larger than a certain curvature. Therefore, the load on the connection part between the lid part 102 and the receiving part 103 is reduced, and it is difficult to come off. The auxiliary component 120 may not be particularly used when sufficient strength can be obtained with the cable protective cover 101 alone. Further, the size of the end column part 21, the bridge part 22 and the auxiliary partition part 23 of the auxiliary component 120 is determined according to the size of the cable protection cover 101, the thickness of the cable 130 to be used, the environment of the device to be attached, and the like. The cable protection cover 101 is designed to have an appropriate size that does not buckle when the cover 101 is bent. Further, the auxiliary partitioning portion 23 is designed so that the size of the hollow portion 115 can be limited so that the cable 130 is not entangled or twisted.

  When the cable protective cover 101 shown in the first embodiment of the present invention is bent, the deformation amount of the lid part 102 and the receiving part 103 is different between the inside and the outside. The wrinkles of the part 106 and the bottom part 107 become large or it becomes difficult to bend.

  The cable protection cover 140 according to the second embodiment of the present invention has been proposed to solve the above problem. FIG. 6 is a perspective view of the cable protection cover 140 according to the second embodiment of the present invention.

  The lid portion 106 of the lid component 141 used in the cable protection cover 140 is not a vent hole 110 similar to that in the first embodiment, but a slit opened from one fitting portion 104 side to the other fitting portion 104 side. Holes 113 are formed at regular intervals in the length direction of the lid component 141.

If the slit hole 113 is formed in this way, the difference in deformation between the lid part 102 and the receiving part 103 can be absorbed by the slit hole 113, and the curve can be smoothly moved. In addition, when the receiving part 103 is curved so that it is on the inner peripheral side, the receiving part 103 is difficult to be deformed so that wrinkles approach, so the load on the connection part between the lid part 102 and the receiving part 103 can be reduced, and the fitting The connection between the mating portion 104 and the fitted portion 105 is difficult to be disconnected. Furthermore, the slit hole 113 functions as a hollow portion 115 and a ventilation hole for outside air, and heat generated by the cable can be released to the outside.

  Although not particularly illustrated, the slit hole 113 may be provided not at the lid component 141 but at the bottom 107 of the receiving component 103, or at both the lid component 141 and the receiving component 103. Further, if necessary, vent holes 110 and 114 as shown in the first embodiment may be provided separately from the slit hole 113.

  When the slit hole 113 is formed in the lid part 102, the cable protection cover 140 is easily bent so that the lid part 102 is on the outside and the receiving part 103 is on the inside, as shown by an arrow A in FIG. . On the other hand, when the slit hole 113 is formed in the receiving part 103, the cable protection cover 140 is easily bent so that the lid part 102 is on the inside and the receiving part 103 is on the outside. Further, when the slit hole 113 is formed in both the lid part 102 and the receiving part 103, the cable protection cover 140 is curved in both the direction in which the lid part 102 is on the outside and the direction in which the lid part 102 is on the inside. Be free.

  In the first and second embodiments, the radius of the circle inside the C-shape of the fitting portion 104 having a C-shaped cross section is slightly smaller than the radius r1 of the fitted portion 105. When the cable protection cover 101 (140) is bent, the fitting portion may be fixed firmly when fitted, or formed slightly larger than the radius r1 of the fitting portion 105. 104 and the fitted part 105 may be shifted in the length direction to facilitate the bending movement.

  Moreover, in the said Example 1 and Example 2, although the case where it connected by inserting the to-be-fitted part 105 of a circular cross section in the fitting part 104 with a C-shaped cross section was demonstrated, The shape of the fitted portion 105 is not limited to this, and may be a shape that can be connected so that the fitted portion 104 and the fitted portion 105 are not easily detached. For example, the cross-sectional shape of the fitting portion 104 is formed in a U-shape, and the cross-sectional shape of the fitted portion 105 is a shape in which the U-shape is turned upside down so that they are hooked to each other. The cross-sectional shape of the fitting portion 104 may be formed in a U shape, the cross-sectional shape of the fitted portion 105 may be circular, and the fitting portion 104 may be hooked to the fitted portion 105 and connected.

  Furthermore, after fitting the fitting portion 104 and the fitted portion 105 and assembling the cable protection cover 101, the fitting portion 104 and the fitted portion 105 are bonded with an adhesive, screwed or riveted. It may be fixed so that it does not come off.
