Description

[Technical field]

[0001] The present invention relates to a cable holder for holding wires or cables (hereinafter collectively referred to as cables). [Background technology]

[0002] In electronic devices and electrical devices, cable holders are used to hold electrical cables to a part of the device body. As such a cable holder, Patent Document 1 discloses a configuration in which a cable is inserted into a U-shaped holder body and a cover, and the cable is clamped between an elastic support piece provided on the holder body and an elastic pressing piece provided on the cover.

[0003] In the cable holder of Patent Document 1, the cable is clamped by elastic pieces, so that when the elastic pieces bend, the clamping force cannot be maintained, the cable is easily moved in the length direction, and the cable holding force is reduced. Therefore, for example, when a cable having a connector for connecting to a device is held, the connection at the connector may come off due to the reduced holding force of the cable. As a technology for increasing the holding force of such a cable in the length direction, Patent Document 2 proposes a technology that is composed of two clamps with tapered outer surfaces that hold the cable, and a fixed block with tapered inner surfaces on both sides, and by abutting the outer surface of the clamp against the inner surface of the fixed block, the clamp ensures the holding force of the cable by the wedge action of the tapered surfaces of both clamps.

[0004] [Patent Document 1] JP 2009-112092 A [Patent Document 2] Patent No. 3378469 Summary of the Invention [Problem to be solved by the invention]

[0005] It is conceivable to apply the technology of Patent Document 2 to Patent Document 1 to provide a cable holder that prevents the cable from moving in the longitudinal direction, but Patent Document 2 requires a fixed block and a clamp that are configured separately. That is, in addition to the cable holder of Patent Document 1, a part equivalent to the clamp of Patent Document 2 is required. This results in an increase in the number of parts that make up the cable holder, as well as a problem that the overall structure of the cable holder becomes complicated, and furthermore a problem of high costs arises.

[0006] An object of the present invention is to provide a cable holder which has an increased cable holding force and which effectively prevents the cable from moving in the longitudinal direction. [Means for solving the problem]

[0007] The cable holder of the present invention is In a vessel The cable clamping device includes a fixing part for fixing the cable and a holding part formed integrally with the fixing part for holding the cable, the holding part includes a bearing piece for supporting the cable, a cover piece for pressing the cable against the bearing piece to clamp it between the bearing piece, a support piece for elastically supporting the bearing piece so that the positions in the length direction of the cable and the direction in which the cable is clamped can be displaced, and a guide rail that extends in the length direction of the cable and is inclined in the direction in which the cable is clamped. The bearing piece is configured to be displaced in one direction in the length direction by the guide rail in the clamping direction.

[0008] For example, in a preferred embodiment of the holding part of the present invention, the holding part comprises a pair of side pieces provided on both sides of a base, a cover piece extending from one of the side pieces, an engagement piece connected to the cover piece and having engagement teeth, an engagement groove provided on the other side piece and having an engagement pawl that engages with the engagement teeth when the engagement piece is inserted, a bearing piece supported by the base and supporting the cable and clamping the cable between the cover piece, a support piece that elastically supports the bearing piece so that the positions of the cable in the length direction and the direction in which the cable is clamped can be displaced, and a guide rail that extends in the length direction and is inclined in the clamping direction from one side to the other in the length direction, and the bearing piece is configured to be displaced in the clamping direction by the guide rail when displaced from one side to the other in the length direction.

[0009] Furthermore, in a preferred embodiment of the present invention, the guide rail has a rail surface against which the support piece abuts, and this rail surface is inclined in a clamping direction so as to approach the cable from one side in the length direction to the other. Also, the support piece has a wedge with a tapered surface, and this tapered surface abuts against the rail surface of the guide rail. In the present invention, the cable is provided with a connector for connecting to the device, and the cable is preferably held in a state in which the side provided with the connector faces one side in the length direction. Also, in the present invention, the support piece is configured to be displaced in a clamping direction by the guide rail when displaced in the length direction, and the guide rail may be configured to include a first guide rail that displaces the support piece in a clamping direction when the support piece is displaced to a first side in the length direction, and a second guide rail that displaces the support piece in a clamping direction when the support piece is displaced to a second side opposite to the first side. Effect of the Invention

[0010] According to the present invention, by displacing the position of the support piece that supports the cable in both the length direction of the cable and the direction in which the cable is clamped using a guide rail, it is possible to increase the holding force of the cable and prevent movement of the cable in the length direction.

[0012] An embodiment of the present invention will now be described. Fig. 1 is a rear view of an application example in which a cable holder 1 according to an embodiment of the present invention is fixed to a rear panel P of a television TV as equipment and used to hold a power cord ACC of the television TV. This power cord ACC has a female plug (cord connector body) WP connected to its tip, which is adapted to be connected to a male plug (power receiving inlet) MP provided on the rear of the television TV. As will be described later, this cable holder 1 holds the power cord ACC and also has a function of preventing the female plug WP from coming off the male plug MP when an external force is applied to the power cord ACC.

[0013] Fig. 2 is a perspective view of cable holder 1 as seen from one side, and Fig. 3 is a perspective view as seen from the opposite direction. Fig. 4(a) is a front view of cable holder 1, and Fig. 4(b) is a cross-sectional view taken along line bb. Cable holder 1 is formed integrally by resin molding of fixing part 2 for fixing to a panel and holding part 3 for holding power cord ACC. In the following explanation, the up-down direction is based on Fig. 2.

[0014] The fixing part 2 includes a pair of V-shaped fitting pieces 21 protruding downward from both ends of a rectangular plate-shaped base 4 in one direction (the left-right direction in Figs. 2 and 3, which is defined as the width direction here), and a pair of elastic contact pieces 22 protruding downward from the center of the base 4. One end of the V-shaped fitting pieces 21 is connected to the base 4, and the other end is configured as a free end, and fitting claws 21a are formed on the outer surface of this free end. As will be described later, these fitting pieces 21 are fitted into a pair of fitting holes H provided in the rear panel P. The elastic contact pieces 22 are elastically deformed by contacting the surface of the rear panel P.

[0015] The holding portion 3 has a pair of side pieces 31, 32 that protrude upward from both ends in the width direction of the base 4. A thin piece 33 is provided at the upper end of the side piece 31 on the left side of Fig. 2, and a plate-shaped cover piece 34 bent at a required angle is connected via this thin piece 33. An arc-shaped engagement piece 35 is connected to the tip of this cover piece 34, and a plurality of sawtooth-shaped engagement teeth, here ratchet teeth 35a, are formed on the outer surface of this engagement piece 35 and arranged at required intervals.

[0016] 2 is thickened, and has an engagement groove 36 that opens downward from its upper end. This engagement groove 36 is curved somewhat in an arc shape corresponding to the engagement piece 35, and an engagement pawl 36a that can mesh with the ratchet teeth 35a of the engagement piece 35 is formed on part of the outer inner surface of this engagement groove 36.

[0017] The holding portion 3 further includes a support piece 37 located at the center in the width direction above the base 4. This support piece 37 is supported on the base 4 by an elastically deformable support piece 38, and its upper surface is formed into a cylindrical surface so as to support the circumferential surface of the held power cord ACC from below. In addition, a protrusion 37a is formed on part of the upper surface of the support piece 37 to increase the contact frictional force with the circumferential surface of the power cord ACC.

[0018] As shown in Figures 3 and 4(a), the support piece 38 is formed as a crank-shaped strip piece that connects the base 4 and the support piece 37. The lower end of this support piece 38 is connected to the end of the base 4, and the upper end is connected to the end of the support piece 37, and is configured to be elastically deformable in the plate thickness direction. Due to the elastic deformation of this support piece 38, the support piece 37 can be moved up and down, and the position in the up and down direction can be displaced. At the same time, it can also be moved in a direction intersecting the width direction, i.e., in the length direction of the power cord ACC when the power cord ACC is held (hereinafter, this direction will be referred to as the length direction), and the position in the length direction can be displaced.

[0019] The support piece 37 has a larger width than the support piece 38, and both sides of the support piece 37 protrude outward beyond the support piece 38. A wedge 39 is formed on each of the both sides, the lower surface of which is tapered. The lower surface of the wedge 39 is inclined at a required angle from one side to the other in the length direction.

[0020] On the other hand, on the inner surfaces of the side pieces 31, 32 on both sides, i.e., on the surfaces where the side pieces 31, 32 face each other, guide rails 30 extending along the length direction are formed in a stepped shape protruding inward. FIG. 5 is a partial perspective view showing the guide rails 30, and the rail surfaces facing upwards of the guide rails 30 are formed as slopes inclined so that the height in the vertical direction changes linearly from one side to the other in the length direction in correspondence with the lower surfaces of the wedges 39. In other words, the guide rails 30 are formed as slopes inclined along the direction in which the power cord ACC is clamped, specifically, slopes in which the height of the rail surface increases continuously from one side to the other in the length direction of the cable holder 1. In other words, they are formed as slopes approaching the electric cord ACC toward the other side. Furthermore, the rail surfaces of the guide rails 30 are disposed directly below the wedges 39 on both sides of the support pieces 37. In the following description, the lower side of the rail surface of the guide rail 30 in the cable holder 1 may be referred to as the low side (Lo) and the higher side as the high side (Hi).

[0021] The cable holder having the above-mentioned configuration is fixed to the rear panel P of a television TV, as shown in Fig. 1. During this fixing, the pair of fitting pieces 21 are each fitted into a fitting hole H of the rear panel P, as shown in the cross-sectional structure in Fig. 6(a). When the fitting pieces 21 are fitted, the fitting claws 23 engage with the inner edge of the fitting hole H on the back side of the rear panel P. At the same time, the elastic contact pieces 22 abut against the surface of the rear panel P and are elastically deformed, and the engagement state of the fitting claws 23 with the fitting hole H is maintained by the reaction force associated with this elastic deformation.

[0022] This fixes the cable holder 1 to the rear panel P. At this time, the opening position and direction of the fitting hole H and the direction of the cable holder 1 are set so that the lower side of the cable holder 1, i.e., the side with the lower height of the rail surface of the guide rail 30, faces the male plug MP arranged on the television TV, as shown in Figures 1 and 2. In other words, the female plug WP provided on the power cord ACC to be held is set to face the lower side of the cable holder 1.

[0023] In addition, with this configuration of the fixing part 2, by pinching the free ends of the pair of fitting pieces 21 from both sides and elastically deforming them inward, the fitting pieces 21 can be pulled out of the fitting hole H. Therefore, the cable holder 1 can be removed from the rear panel P and can be used as a reused part.

[0024] Then, as shown in Fig. 2, the cover piece 34 of the cable holder 1 is opened, and the power cord ACC is inserted between the two side pieces 31, 32 of the cable holder 1. Next, as shown in Fig. 6(a), the cover piece 34 is moved inward while deforming the thin piece 33, and at the same time, the engagement piece 35 is inserted from the tip side into the engagement groove 36, and the ratchet teeth 35a are engaged with the engagement claw 36a. A holding space for holding the power cord ACC is formed by the side pieces 31, 32 on both sides and the cover piece 34, and as will be described later, the power cord ACC is held in this holding space.

[0025] 6(a) shows the case where the power cord ACC has a relatively small diameter, with the cover piece 34 abutting against the upper part of the periphery of the power cord ACC and further being pushed downward by this cover piece 34. Also, as the power cord ACC is pushed by the cover piece 34, the lower part of the periphery of the power cord ACC abuts against the support piece 37. Since the upward elastic force of the support piece 38 is applied to the support piece 37, the power cord ACC is clamped in the vertical direction by this elastic force between the cover piece 34 and the support piece 37. In this way, the power cord ACC is held by the cable holder 1.

[0026] When the diameter of the power cord ACC becomes relatively large, as shown in Figure 6(b), the length by which the engagement piece 35 is inserted into the engagement groove 36 becomes shorter, but one of the ratchet teeth 35a engages with the engagement pawl 36a. Even in this case, when the power cord ACC is pushed downward by the cover piece 34, the support piece 37 is pushed downward and moved integrally with the power cord ACC, and the power cord ACC is clamped in the vertical direction between the cover piece 34 and the support piece 37 due to the upward elastic force of the support piece 38.

[0027] When the diameter of the power cord ACC reaches a predetermined size or larger, the power cord ACC is pressed downward by the cover piece 34, and the support piece 37 is also pressed downward, causing the support piece 38 to elastically deform, and the wedges 39 on both sides of the support piece 37 come into contact with the guide rail 30. When the wedges 39 come into contact with the guide rail 30, an upward resistance is applied to the support piece 37 from the guide rail 30, and this resistance acts as part of the force that clamps the power cord ACC. This increases the clamping force for the power cord ACC, improving the holding effect.

[0028] Here, since the multiple ratchet teeth 35a of the engagement piece 35 are arranged at required intervals, when any one of the ratchet teeth 35a and the engagement pawl 36a engages, the vertical spacing dimension formed between the cover piece 34 and the support piece 37 becomes a stepped (discrete) dimension. Therefore, when this spacing dimension and the diameter dimension of the power cord ACC are not the same and there is a difference between the two dimensions, particularly when the spacing dimension is larger than the diameter dimension, this dimensional difference appears as looseness when the power cord ACC is clamped, and the holding force of the power cord ACC decreases.

[0029] In this cable holder 1, as shown in Fig. 7(a), when the power cord ACC is pushed downward by the cover piece 34, the support piece 37 is pushed downward integrally with the cover piece 34, and the tapered surface of the wedge 39 comes into contact with the rail surface of the guide rail 30. Then, the support piece 37 slides in the length direction along the slope of the rail surface while keeping the tapered surface of the wedge 39 in contact with the guide rail 30, and this sliding causes the support piece 37 and the wedge 39 to be displaced in the vertical direction. This displacement amount is continuous because the rail surface is a slope. That is, the position of the support piece 37 in the direction where it clamps the power cord ACC with the cover piece 34 is displaced, and as a result, the distance between the support piece 37 and the cover piece 34 is changed. This absorbs the difference in size occurring with the diameter of the power cord ACC, prevents a decrease in the clamping force of the cover piece 34 and the support piece 37, and enables suitable holding.

[0030] 7(b), when an external force is applied to the power cord ACC in a direction that pulls the female plug WP out of the male plug MP while the power cord ACC is being held by this cable holder 1, that is, when the power cord ACC is about to move from the low side (Lo) to the high side (Hi) of the cable holder 1, the support piece 37 is displaced integrally to the high side (Hi) as the power cord ACC moves. In particular, the support piece 37 is formed with a ridge 37a, which bites into the circumferential surface of the power cord ACC to increase the frictional force between them, so that when the power cord ACC is moved, the support piece 37 is displaced integrally.

[0031] When the tapered surface of the wedge 39 slides toward the higher side (Hi) on the rail surface of the guide rail 30 due to this displacement of the support piece 37, the slope of the rail surface displaces the support piece 39 upward. That is, it is displaced in the direction of clamping the power cord ACC, and the contact force against the circumferential surface of the power cord ACC is increased. At the same time, the wedge 39 of the support piece 37 functions as a wedge that is inserted between the circumferential surface of the power cord ACC and the rail surface of the guide rail 30. This wedge action prevents further movement of the power cord ACC, preventing the female plug WP from being pulled out of the male plug MP.

[0032] When the external force applied to the power cord ACC is in the opposite direction, i.e., when the power cord ACC is moved to the lower side of the cable holder 1, the tapered surface of the wedge 39 of the support piece 37 slides along the rail surface of the guide rail 30 to the lower side (Lo), and the support piece 37 is displaced downward in the opposite direction to the direction in which the power cord ACC is clamped. This reduces the clamping force between the cover piece 34 and the support piece 37, making it possible for the power cord ACC to be moved relative to the cable holder 1. Therefore, if the power cord ACC is intentionally moved in this direction, the power cord ACC can be bent on the lower side of the cable holder 1, and the female plug WP can be easily removed from the male plug MP.

[0033] In the cable holder 1 of the embodiment, by forcibly elastically deforming outward the release piece 32b that protrudes outward from the tip of the side piece 32 shown in Fig. 6, the engagement between the ratchet teeth 35a and the engagement pawl 36a is released, and the engagement piece 35 can be pulled out of the engagement groove 36. In other words, the hold on the power cord ACC can be released.

[0034] Fig. 8 is a perspective view of a cable holder 1A according to a modified example of the present invention. Fig. 9(a) is a front view, and Fig. 9(b) is a cross-sectional view taken along line bb. This modified example is configured to prevent movement of the cable in both longitudinal directions. For example, although not shown, this is applied to prevent the two plugs from coming off when plugs are connected to both ends of an electric cord and electrically connected to devices, etc. The same reference numerals are used to designate parts equivalent to those in the embodiment, and detailed description thereof will be omitted.

[0035] As shown in Figs. 8 and 9, in the cable holder 1A of the modification, a pair of wedges 39 are formed on both sides in the width direction of the support piece 37 supported by the support piece 38 in the same manner as in the embodiment. Here, the outer wedge 39A of the pair is called the first wedge, and the inner wedge 39B of the pair sandwiched between them is called the second wedge. The lower surfaces of the first wedge 39A and the second wedge 39B are each formed as a tapered surface, but the inclination directions of the tapered surfaces are directed in opposite directions. The tapered surface of the first wedge 39A is inclined so as to become higher toward the first side in the length direction. This is the same direction as the wedge 39 of the embodiment, and the first side is the high (Hi) side of the embodiment. On the other hand, the tapered surface of the second wedge 39B is inclined so as to become higher toward the opposite second side, that is, the low (Lo) side of the embodiment. The tapered surfaces of the first wedge 39A and the second wedge 39B are formed to have the same inclination angle, but the inclination angles do not necessarily have to be the same.

[0036] Also, on the inner surface of each side piece 31, 32 on both sides of the cable holder 1A, a pair of guide rails 30 extending along the length direction is formed as in the embodiment. The pair of outer guide rails 30A is called the first guide rail, and the pair of inner guide rails 30B sandwiched between them is called the second guide rail. These guide rails 30A, 30B are formed at positions corresponding to the first wedge 39A and the second wedge 39B in the width direction of the cable holder 1A. Also, these first guide rail 30A and second guide rail 30B are formed as slopes inclined such that the rail surface facing upward changes linearly in the vertical height along the length direction. Here, the rail surface of the first guide rail 30A is higher on the first side than on the second side as in the embodiment. On the other hand, the rail surface of the second guide rail 30B is higher on the second side than on the first side.

[0037] Here, the inclination angle of the rail surface of the first guide rail 30A is set equal to the inclination angle of the tapered surface of the first wedge 39A. The inclination angle of the rail surface of the second guide rail 30B is set equal to the inclination angle of the tapered surface of the second wedge 39B. The inclination angles of the rail surfaces of the first guide rail 30A and the second guide rail 30B are set equal, but they do not necessarily have to be equal. In this modification, the inclination angles of both guide rails 30A and 30B are set equal, and the heights of the rail surfaces at the midpoints of the length of both guide rails 30A and 30B are set equal, so that when the cable holder 1A is viewed from the width direction, the rail surfaces cross each other at this midpoint.

[0038] 10(a), when the cable holder 1A holds the power cord ACC, the power cord ACC is clamped between the support piece 37 and the cover piece 34 as in the embodiment, and the power cord ACC is suitably held by the clamping force of the cover piece 34 and the support piece 37. At this time, the tapered surface of the first wedge 39A abuts against the rail surface of the first guide rail 30A. Alternatively, the tapered surface of the second wedge 39B abuts against the rail surface of the second guide rail 30B. Either or both of these abutments generate a resistance force on the support piece 37, which becomes the clamping force between the cover piece 34 and the support piece 37.

[0039] In this cable holder 1A, as shown in Fig. 10(b), when the power cord ACC is held and is about to be moved from the second side to the first side, the support piece 37 is displaced integrally to the first side with the movement of the power cord ACC. When the tapered surface of the first wedge 39A slides on the rail surface of the first guide rail 30A toward the first side due to the displacement of the support piece 37, the first wedge 39A is displaced upward due to the slope of the rail surface. Therefore, the support piece 37 is displaced in a direction to clamp the power cord ACC, and the contact force between the support piece 37 and the cover piece 34 against the circumferential surface of the power cord ACC is increased. At this time, the first wedge 39A functions as a wedge that is inserted between the circumferential surface of the power cord ACC and the rail surface of the first guide rail 30A, and this wedge action prevents the power cord ACC from moving further toward the first side.

[0040] On the other hand, when the external force applied to the power cord ACC is in the opposite direction, that is, when the power cord ACC is moved to the first side of the cable holder 1, the support piece 37 is displaced integrally to the second side with the movement of the power cord ACC, as shown in Fig. 10(c). When the tapered surface of the second wedge 39B slides toward the second side on the rail surface of the second guide rail 30B due to the displacement of the support piece 37, the second wedge 39B is displaced upward due to the slope of the rail surface. Therefore, the support piece 37 is displaced in the direction of clamping the power cord ACC, and the contact force between the support piece 37 and the cover piece 34 against the circumferential surface of the power cord ACC is increased. The second wedge 39B functions as a wedge that is inserted between the circumferential surface of the power cord ACC and the rail surface of the second guide rail 30B, and this wedge action prevents the power cord ACC from moving further to the second side.

[0041] In this way, when the cable holder 1A of the modified example holds the electric cord ACC, it prevents the electric cord ACC from moving to the first side and also prevents the electric cord ACC from moving to the opposite second side. That is, the held electric cord ACC is prevented from moving in either direction along its length. Therefore, for example, when plugs are connected to both ends of the electric cord ACC and the two ends are electrically connected to devices, it is possible to prevent the plugs from coming loose.

[0042] In the modified example, the first wedge 39A and the first guide rail 30A are disposed outside the second wedge 39B and the second guide rail 30B, but the second wedge 39B and the second guide rail 30b may be disposed outside the first wedge 39A and the first guide rail 30A. Alternatively, the first wedge 39A and the second wedge 39B, and the first guide rail 30A and the second guide rail 30B may be disposed alternately in the width direction as long as they are disposed opposite each other.

[0043] The above embodiments and modified examples have shown examples of the cable holder of the present invention being used to hold a power cord for a television power source, but the present invention is not limited to this and may be configured as a holder for holding various types of electrical cords, electrical cables, or other cables.

[0044] The guide rail configuration, particularly the slope of the rail surface, does not have to be a linearly inclined surface, but may be configured as a curved inclined surface that is convex or concave upward. In this way, the amount of displacement in the direction in which the support piece clamps the cable when the support piece moves along the guide rail with the movement of the cable can be appropriately designed, and the clamping force of the cable can be appropriately adjusted. In addition, the tapered surface of the wedge of the support piece may be formed into a convex or concave curved surface corresponding to the shape of the rail surface of the guide rail.

[0045] The structure of the fixing part for fixing the cable holder to an apparatus or the like in the present invention is not limited to that of the embodiment, but may be a fixing structure with a different fitting form, or a fixing structure using a fixing member such as a screw.
