Description

【Technical Field】 【0001】 The present invention relates to a harness holding structure. 【Background Art】 【0002】 Conventionally, inside image forming apparatuses such as copiers, printers, facsimiles, or multifunction devices integrating these functions, and other electronic devices, a large number of harnesses for power supply and signal transmission are routed. In order to prevent contact with non-contact members such as movable parts inside the device, the routing path (layout path) of the harnesses is regulated by harness clamps. 【0003】 A general harness clamp has a holding part for holding a harness and a shaft part that is integrally formed with the holding part and inserted into a mounting hole formed in the base member of the device, like the cable clamp of Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2017-32017). The harness clamp is supported so as to be rotatable about the shaft part in order to provide some margin in the layout path. A regulating member for regulating the rotation range of the harness clamp is disposed on the side of the mounting hole. 【Disclosure of the Invention】 【Problems to be Solved by the Invention】 【0004】 Conventional regulating members are separate members independent of the base member and are attached to the base member by screws, adhesion, or the like. When using such separate regulating members, there is a problem of increased cost due to an increase in the number of parts and the number of mounting steps. 【0005】 Therefore, an object of the present invention is to reduce the number of parts and the number of mounting steps of the harness holding structure. 【Means for Solving the Problems】 【0006】 To achieve the above objectives, the harness holding structure of the present invention comprises a flat base member and a harness clamp for clamping a harness, wherein the harness clamp is rotatably attached to the base member, and is characterized in that a part of the base member is bent to form an upright portion rising from the base member, and the upright portion is positioned within the rotational range of the harness clamp. [Effects of the Invention] 【0007】 According to the present invention, the number of parts and installation time for the harness holding structure can be reduced.

[Modes for carrying out the invention] 【0009】 Hereinafter, the harness holding structure according to the embodiment of the present invention will be described in detail with reference to the drawings. It is needless to say that the harness holding structure shown in the drawings is exemplary and not limited thereto. 【0010】 As shown in FIGS. 1A and 1B, a harness holding structure 100 according to an embodiment of the present invention includes a flat base member 10 and a harness clamp 30 rotatably supported on the base member 10. The harness H routed on the base member 10 is held (clamped) by the harness clamp 30, thereby regulating its routing path. 【0011】 As shown in FIG. 2, the base member 10 is in the shape of a rectangular plate formed of sheet metal or the like, and one side end thereof is bent upward in a V shape (at an acute angle). Thereby, a standing portion 11 rising from the base member 10 is formed at one side end of the base member 10. 【0012】 This standing portion 11 is located within the rotation range centered on the shaft portion 36 of the harness clamp 30. Thereby, there is no need to add a separate component for restricting the rotation of the harness clamp 30, nor is there a need to use a clamp or the like having a special structure for restricting rotation. Therefore, it is possible to restrict the rotation of the harness clamp 30 with a low-cost configuration, avoiding an increase in cost due to an increase in the number of parts and the number of mounting steps. 【0013】 The standing portion 11 extends linearly along one side of the base member 10 in a plan view. One shaft hole 12a penetrating the base member 10 in the vertical direction is formed near the central portion in the longitudinal direction of the standing portion 11. 【0014】 On the other hand, as shown in FIG. 3, the harness clamp 30 has a columnar shaft portion 36. The shaft portion 36 is inserted into the shaft hole 12a of the base member 10 so as to be rotatable from above downward. 【0015】 The tip 36a of the shaft portion 36 is formed in an umbrella shape (truncate cone shape) to prevent it from coming loose. The shaft portion 36 is preferably cylindrical, but it may also be prism-shaped, elliptical, or other shapes. 【0016】 The harness clamp 30 has a U-shaped main body 31 with a shaft portion 36 formed on its lower surface, a receiving portion 35 formed by a V-shaped notch formed on one end of the main body 31, and a cap portion 32 on the opposite side of the main body 31 that can move up and down (open and close) around a hinge portion 33. The shapes of the main body 31 and the cap portion 32 may be arc-shaped to correspond to the outer shape of the harness H. 【0017】 A V-shaped projection 34 is formed at the tip of the cap portion 32. After housing the harness H inside the main body portion 31 of the harness clamp 30, the harness H can be positioned inside the main body portion 31 by closing the cap portion 32 and fitting the projection 34 into the receiving portion 35. 【0018】 A small gap is formed between the harness clamp 30 and the upright portion 11. This gap allows the harness clamp 30 to rotate at a small angle around the shaft portion 36. This small angle of rotation of the harness clamp 30 creates some leeway in the routing path of the harness H, preventing the harness H from coming into contact with movable parts or other non-contactable components, and also preventing excessive force from being applied to the harness H. 【0019】 Figures 4A and 4B show a modified embodiment of the base member 10. In this modified embodiment, a rectangular notch 12b is formed on one side of the base member 10, and the upright portion 11 rises from the inner edge of this notch 12b. 【0020】 The upright portion 11 can be formed by cutting and bending the inner plate-shaped member of the notched hole 12b. This modified embodiment is advantageous when the harness clamp 30 and the upright portion 11 are to be positioned closer to the center of the base member 10. 【0021】 Figure 5 shows a modified embodiment of the base member 10. In this modified embodiment, a trapezoidal notch 14 is formed in the longitudinal center of the upright portion 11. Therefore, the harness H passes through a part of the notch 14. 【0022】 This allows for the formation of a sufficient gap D between the lowest part of the notch 14 and the harness H. Therefore, it is possible to prevent the harness H from coming into contact with the upright portion 11 and being damaged without changing the desired routing path of the harness H. 【0023】 Figures 6A and 6B show a modified embodiment of the base member 10. In this modified embodiment, the upright portion 11 extends inward from the base member 10, as shown in Figure 6A. 【0024】 A single axial hole 12a is formed near the longitudinal center of the upright portion 11, penetrating the base member 10 in the vertical direction. A harness clamp 30, which holds the harness H, is rotatably supported in this axial hole 12a. This modified embodiment is advantageous when a routing path for the harness H is provided along the side end of the base member 10. 【0025】 Figures 7A and 7B show a modified embodiment of the base member 10. In this modified embodiment, the upright portion 11 is formed along the arm portion 13 that extends outward from the base member 10. 【0026】 An axial hole 12a is formed in the longitudinal center of the arm portion 13. The harness clamp 30 is rotatably supported in this axial hole 12a. 【0027】 The arm portion 13 may extend horizontally, or it may extend at a slight downward inclination from the horizontal. By increasing or decreasing the inclination angle of the arm portion 13, the degree of freedom in the routing path of the harness H can be increased. 【0028】 Figures 8A and 8B show a modified embodiment of the base member 10. In this modified embodiment, the upright portion 11 (the tip portion) is formed only on one side of one edge of the base member 10. 【0029】 In other words, by forming a notch 14 in most of the upright portion 11 that extends linearly along one side of the base member 10, the extension range of the upright portion 11 is limited. The notch 14 expands the rotatable range of the harness clamp 30. 【0030】 In other words, in Figure 8B(a), the harness clamp 30 cannot be rotated clockwise, but it can be rotated counterclockwise. This modified embodiment is advantageous when you want to bend the right end of the harness H in Figure 8B(a) upwards for routing. 【0031】 Figures 9A and 9B show a modified embodiment of the base member 10. In this modified embodiment, the upright portion 11 (the tip portion) is formed in pairs on both sides of one side of the base member 10. A notch 14 is formed in the middle of the pair of upright portions 11. 【0032】 This modified embodiment is advantageous when it is desired to restrict the rotation of the harness clamp 30 in both clockwise and counterclockwise directions. This allows for a straight routing path for the harness H. 【0033】 Figure 10 shows a modified embodiment that accommodates a larger harness clamp 30. In this modified embodiment, the base member 10 and the pair of upright parts 11 are made larger to accommodate the harness clamp 30 compared to Figure 9B. The harness clamp 30 can also hold multiple harnesses H at once. 【0034】 Figure 11 shows the harness clamp 30 positioned to the side of the non-contactable member OB. The rotation of the harness clamp 30 is restricted by the upright portion 11 of the base member 10, thereby restricting the routing path of the harness H so that it does not come into contact with the non-contactable member OB. 【0035】 Figures 12A and 12B show a case where the rotation of the harness clamp 30 is restricted by a pair of upright portions 11 that rise from the inner edge of the notch hole 12b of the base member 10. By restricting the rotation of the harness clamp 30 in both clockwise and counterclockwise directions with the pair of upright portions 11, the routing path of the harness H is restricted so that it does not come into contact with the pair of non-contact members OB, for example, as shown in Figure 12B. 【0036】 Figures 13A and 13B show a configuration in which an upright portion 11 is formed along an arm portion 13 extending outward from the base member 10, and a harness clamp 30 is rotatably supported in the axial hole 12a of this arm portion 13. In this configuration, for example, as shown in Figure 13B, the harness clamp 30 can be positioned at a distance from the base member 10, thereby increasing the distance from the non-contact member OB on the base member 10 to the harness H. 【0037】 Figures 14(a) and 14(b) are perspective views showing an example of harness clamps 30 being installed around a motor M and a sensor S. Gears G and other non-contactable components are present around the motor M. The harness H, extending from the motor M and sensor S, is routed using the harness clamps 30 to prevent contact with these non-contactable components. 【0038】 Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. That is, for example, the harness clamp 30 is not limited to the shape shown in Figure 3, but may have any shape and structure that can clamp (hold) the harness H. Also, the upright portion 11 of the base member 10 may be formed on both opposing side edges of the base member 10.
