Description

  The present invention relates to a cable fixing bracket used for fixing three cables to a structure such as a vehicle body.

  When routing three cables, it is necessary to fix the cables at predetermined locations. Various types of cable fixing brackets used at this time have been developed.

  For example, the types as shown in Patent Documents 1 to 3, that is, the linear type in which three cables are arranged in a straight line in a sectional view, and the type as shown in Patent Document 4, that is, three cables in cross section. There is a triangular type fixing bracket for cables arranged in a triangular shape as viewed.

  In the former linear type cable fixing bracket, not only the cabling space is increased in the cable arrangement direction, but, for example, when attaching to a vehicle body or the like, there are two attachment portions at both ends in the cable arrangement direction. There is a problem that it is necessary to form, and the installation space becomes wide.

  Therefore, the present applicant focused on the latter triangular type cable fixing bracket, and as a result of examination, as a result, the triangular type cable fixing bracket has a mounting portion in one place when being attached to a vehicle body or the like. It is effective not only in that the installation space can be saved, but also in that the triangular cable arrangement in the cross-sectional view contributes to the space saving of the wiring space. Thought.

  However, there is Patent Document 4 as a conventional triangular type cable fixing bracket. However, the cable fixing bracket of Patent Document 4 has the following problems. In particular, the problem is remarkable when used for vehicles.

  In the cable fixing bracket of Patent Document 4, the arrangement of the three cables itself is triangular, but the support bracket and the cable support member have a circular shape, so that the cable fixing bracket is a portion for fixing the cable. The search space is large and there is room for improvement in terms of space saving.

  Further, in the cable fixing bracket for a vehicle, vibration becomes a problem. However, in the cable fixing bracket of Patent Document 4, since the cable support member sandwiched between the support brackets is circular, the vibration causes the support bracket to be fixed. On the other hand, the cable support member may rotate, which is not desirable from the viewpoint of cable positioning.

  Furthermore, in the cable fixing bracket of Patent Document 4, since the cable is inserted into the cable insertion hole of the cable support member, a gap is formed between the cable support member and the cable, and vibration causes The cable is liable to slip, which is not desirable from the viewpoint of cable positioning.

  If the cable is not positioned properly, that is, if the cable is not firmly fixed to the cable fixing bracket, the cable will be twisted, and unnecessary force will be applied to the cable. May be easily disconnected, and the wiring layout may be changed from the intended layout due to the twisting of the cable, and the cable may interfere with surrounding members, thereby causing a problem.

  The present invention has been made in view of the above circumstances, and can provide a cable fixing bracket capable of realizing space saving in cable routing and capable of firmly fixing the cable. Objective.

  The present invention has been developed to achieve the above object, and is formed in a triangular shape along the outer periphery of three cables arranged in a triangular shape in a cross-sectional view, and one of the three cables.

Separate the two insertion holes As to, and a cable fixing member that is divided into two pieces as the divided direction is divided and vertical directions of the fixing bracket body.

  One of the divided fixing brackets obtained by dividing the fixing bracket main body into two has a partition wall separating the first cable insertion hole and the second cable insertion hole longer than the other divided fixing bracket. The insertion hole and the second cable insertion hole may be deeper than the other divided fixing bracket.

  The mounting flange portion is formed by overlapping plate-shaped split mounting flange portions each provided so as to extend outward from an end portion on the first cable insertion hole side of the split fixing bracket obtained by dividing the fixing bracket main body into two parts. Formed at both ends of the divided fixing metal fittings on the second cable insertion hole side are provided with plate-like fixing flanges extending outward from the end of the second cable insertion hole side, The both split fixing metal fittings may be fixed integrally by overlapping and fixing both split mounting flange portions and overlapping and fixing the both fixing flange portions.

  The mounting flange portion is formed by overlapping plate-shaped split mounting flange portions each provided so as to extend outward from an end portion on the first cable insertion hole side of the split fixing bracket obtained by dividing the fixing bracket main body into two parts. A plate-like fixing flange portion is formed at the end of the both split fixing brackets on the second cable insertion hole side so as to overlap along the split direction when the two split fixing brackets are integrated. The both split fixing brackets may be integrally fixed by being provided and fixed by overlapping the both split mounting flange portions and by overlapping and fixing the both fixing flange portions.

  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

  1A and 1B are diagrams showing a cable fixing bracket according to the present embodiment, in which FIG. 1A is a perspective view and FIG. 1B is an exploded perspective view.

  As shown in FIGS. 1A and 1B, a cable fixing bracket 1 includes a fixing bracket main body 2, a mounting flange portion 3 formed integrally with the fixing bracket main body 2, and a cable support member 4. I have.

  The fixing bracket body 2, more specifically, the outer peripheral shape of the fixing bracket body 2 is substantially triangular in sectional view so as to be along the outer periphery of three cables (not shown) arranged in a triangular shape in sectional view. It is formed.

  The three cables supply power to, for example, an in-wheel motor built in the wheel of the wheel, and the cable fixing bracket 1 includes, for example, three cables extending from the in-wheel motor. Used to fix to.

  As the three cables, a cable composed of a central conductor and an insulator covering the periphery of the central conductor may be used, or a cable including an outer conductor for shielding (that is, a coaxial cable) may be used.

  The fixture main body 2 includes a first cable insertion hole 5 to which one of the three cables is fixed, a second cable insertion hole 6 to which two of the three cables are fixed, have. The first cable insertion hole 5 is formed in a substantially circular shape in sectional view so as to follow the outer periphery of the substantially circular cable in sectional view. The second cable insertion hole 6 is formed in a substantially oval shape (a shape formed by two parallel straight lines and two arc-shaped curves connecting ends of both straight lines) in a cross-sectional view. Both cable insertion holes 5 and 6 are formed so that the center part thereof is aligned with the center part in the width direction of the fixture body 2 (in the direction from the right front to the left back in FIG. 1A).

  The fixing metal body 2 is divided into two parts so that the first cable insertion hole 5 and the second cable insertion hole 6 are divided. Those obtained by dividing the fixing metal body 2 into two parts are referred to as divided fixing metal parts 2a and 2b. In the present embodiment, the fixture main body 2 is divided into two at the center in the width direction. The dividing direction of the fixing metal body 2 is the direction from the right front side to the left back side in FIG.

  The mounting flange portion 3 extends outward from the end of the divided fixing fittings 2a and 2b obtained by dividing the fixing fitting main body 2 into two on the first cable insertion hole 5 side (the end on the right rear side in FIG. 1A). In this way, the plate-like divided mounting flange portions 3a and 3b respectively provided are overlapped. The mounting flange 3 is formed with a plurality of through holes 7 through which fixing bolts (not shown) are passed so as to penetrate both the split mounting flanges 3a and 3b. The cable fixing bracket 1 is fixed to the attachment target structure by passing a bolt through the through hole 7 and fixing the bolt to the attachment target structure (vehicle body or the like) using a nut or the like.

  From the surface opposite to the mounting surface of the mounting flange 3, in other words, the surface on the side where the head of the bolt is located when the bolt is mounted (the front right surface in FIG. 1 (a)), A deformation preventing rib 8 is formed so as to extend to 2. The deformation preventing rib 8 is for preventing deformation of the mounting flange portion 3, and is formed to extend perpendicular to the mounting flange portion 3.

  Further, the ends of the split fixing brackets 2a and 2b on the second cable insertion hole 6 side (the end on the left front side in FIG. 1A) are outward from the end on the second cable insertion hole 6 side. Are provided with plate-like fixing flange portions 9a and 9b. Here, the fixing flange portions 9a and 9b are formed so as to extend in the opposite direction to the mounting flange portion 3 (in FIG. 1A, the direction from the right back to the left front). A plurality of through holes 10 through which fixing bolts (not shown) are passed are formed in the fixing flange portions 9a and 9b so as to pass through the fixing flange portions 9a and 9b.

  The fixing bracket body 2 has both split mounting flange portions 3a and 3b overlapped and fixed with bolts, and both fixing flange portions 9a and 9b are overlapped and fixed with bolts, whereby both split fixing brackets 2a and 2b are fixed. Are fixed at both ends, and are configured to be integrated. The mounting flange portion 3 (divided mounting flange portions 3a and 3b) serves to fix the cable fixing bracket 1 to the structure to be attached and to fix both the split fixing brackets 2a and 2b as a unit.

  Both split fixing brackets 2a and 2b are formed by cutting a lump-shaped metal material. Although it is possible to form both split fixing brackets 2a and 2b by deforming one metal plate by press working, it is difficult to form both split fixing brackets 2a and 2b accurately by pressing. In addition, it is not preferable because it causes a position shift of the cable due to vibration when used for a vehicle.

  The cable support member 4 has two insertion holes 11 to which two cables are fixed, and is formed in substantially the same cross-sectional shape (substantially oval shape) as the second cable insertion hole 6. The cable support member 4 is housed and fixed in the second cable insertion hole 6 with two cables fixed to the two insertion holes 11. That is, the two cables are fixed to the second cable insertion hole 6 of the fixture main body 2 via the cable support member 4.

  It is desirable that the size of the cable support member 4 in a sectional view is slightly larger than the size of the second cable insertion hole 6 in a sectional view. Thereby, when the cable support member 4 is accommodated in the second cable insertion hole 6, the cable support member 4 is pressed by the fixing metal body 2, and the cable support member 4 is firmly fixed to the fixing metal body 2. It becomes possible. The cable support member 4 is made of a metal such as aluminum, a resin, or rubber.

  In the cable fixing bracket 1 according to the present embodiment, the cable support member 4 divides the two insertion holes 11 and the dividing direction is perpendicular to the dividing direction of the fixing bracket main body 2 (FIG. 1 ( In a), a two-divided configuration is adopted so as to be in the direction from the left front to the right back. That is, the cable support member 4 is divided horizontally with respect to the vertical division of the fixture main body 2. Here, the cable support member 4 is divided into two at the center in the direction where the thickness of the oval is thin (in the direction from the left front to the right back in FIG. 1A). The cable support member 4 divided into two parts is referred to as divided cable support members 4a and 4b.

  The cable support member 4 is formed such that its length (length along the cable longitudinal direction) is substantially the same as the length of the fixture body 2 (length along the cable longitudinal direction). At both ends of the cable support member 4 in the cable longitudinal direction, flange portions 12 are formed by expanding both ends of the cable support member 4, and cable support is provided at the periphery of the second cable insertion hole 6 of the fixing bracket body 2. An accommodation recess 13 for accommodating the flange portion 12 of the member 4 is formed. The flange portion 12 and the housing recess 13 are for preventing the cable support member 4 from being displaced in the cable longitudinal direction with respect to the fixture main body 2.

  When fixing the three cables to the cable fixing bracket 1, first, two of the three cables are sandwiched between the split cable support members 4 a and 4 b, and are inserted into the insertion holes 11 of the cable support member 4. Accommodates two cables. Thereafter, the cable support member 4 is accommodated in the second cable insertion hole 6 of one of the divided fixing brackets 2a (or 2b), and one of the three cables is accommodated in the first cable insertion hole 5, Both the split fixing brackets 2 a and 2 b are overlapped, and the cable support member 4 is held in the second cable insertion hole 6 and one cable is held in the first cable insertion hole 5. Thereafter, the fixing flange portions 9a and 9b are overlapped and fixed with bolts, and the mounting flange portion 3 where the both divided mounting flange portions 3a and 3b are overlapped is fixed to the structure to be attached with bolts.

  The operation of the present embodiment will be described.

  In the cable fixing bracket 1 according to the present embodiment, the fixing bracket main body 2 is divided into two parts so as to divide the first cable insertion hole 5 and the second cable insertion hole 6, and the cable support member 4 includes two pieces. A two-divided configuration is adopted so that the insertion hole 11 is divided and the dividing direction is perpendicular to the dividing direction of the fixing metal body 2.

  Compared with the case where the dividing direction of the cable support member 4 is set to the same direction as the dividing direction of the fixing bracket body 2 by making the dividing direction of the cable support member 4 perpendicular to the dividing direction of the fixing bracket body 2, Unnecessary stress (load) can be prevented from being applied to the two cables supported by the cable support member 4.

  Further, in the cable fixing bracket 1, two cables are fixed to the fixing bracket body 2 via the cable support member 4, so that the two cables are firmly fixed to the fixing bracket body 2. Even when the cable fixing bracket 1 is used for a vehicle, it is possible to suppress the occurrence of the displacement of the cable due to vibration.

  Furthermore, in the cable fixing bracket 1, since the cable support member 4 and the fixing bracket main body 2 are divided into two parts, the work of fixing three cables to the cable fixing bracket 1 becomes easy. Therefore, workability when routing the cable can be improved.

  In addition, it is conceivable to hold the two cables directly in the second cable insertion hole 6 without using the cable support member 4, but in this case, unnecessary stress (load) is applied to the two cables, The two cables may be excessively deformed, and the deformation may cause the cable to be disconnected or the electrical characteristics of the cable to be deteriorated.

  Furthermore, when the cable is fixed only by the fixing bracket body 2 without using the cable support member 4, there is a possibility that the cable may not be fixed firmly due to deformation of the fixing bracket body 2 due to external force or processing failure of the fixing bracket body 2. According to the cable fixing bracket 1 of the present invention, since the two cables can be more firmly fixed by the cable support member 4, the deformation of the fixing bracket body 2 due to external force or the processing failure of the fixing bracket body 2 is possible. Even if there is, the shape is maintained and the cable can be firmly fixed. Therefore, reliability can be improved. Furthermore, in the cable fixing bracket 1 of the present invention, the fixing bracket main body 2 is formed by shaving, so that the fixing bracket main body 2 is less likely to be deformed by an external force than when a metal plate is used.

  Further, in the cable fixing bracket 1, two cables are fixed to the fixing bracket main body 2 via the cable support member 4, so that it is like a conventional cable fixing bracket in which the cable is inserted into the cable insertion hole. No gap is formed around the cable. Thus, the cable can be firmly fixed and positioned. Moreover, since the operation | work which penetrates a cable to a cable insertion hole conventionally is unnecessary, the workability | operativity in cable routing can be improved.

  Furthermore, in the cable fixing bracket 1, since the fixing bracket body 2 is formed in a triangular shape along the outer periphery of the three cables arranged in a triangular shape in a cross-sectional view, the entire cable fixing bracket 1 is reduced in size. The wiring space in the cable fixing bracket 1 can be reduced, which contributes to space saving. Moreover, since the cable support member 4 is not rotated by vibration, the cable can be firmly fixed and positioned.

  Furthermore, in the cable fixing bracket 1, since the deformation preventing rib 8 is formed in the mounting flange portion 3, the deformation of the mounting flange portion 3 can be prevented.

  Next, another embodiment of the present invention will be described.

  The cable fixing bracket 21 shown in FIGS. 2 and 3 has basically the same configuration as that of the cable fixing bracket 1 of FIG. 1, and the shapes of the fixing flange portions 22a and 22b are different.

  In the cable fixing bracket 21, the fixing flange portions 22a and 22b are formed so as to overlap along the dividing direction (left and right in FIG. 3A) when the two divided fixing brackets 2a and 2b are integrated. The

  More specifically, the fixing flange portion 22a formed on the left split fixture 2a in FIG. 3A is connected to the split fixture 2b from the end of the split fixture 2a on the second cable insertion hole 6 side. A fixing flange portion 22b formed on the right split fixing bracket 2b in FIG. 3A is formed so as to extend along the split direction of the fixing bracket main body 2 (right direction in FIG. 3A). , Extending from the end of the divided fixing bracket 2b on the second cable insertion hole 6 side toward the divided fixing bracket 2a along the dividing direction of the fixing bracket main body 2 (left direction in FIG. 3A), and both divided When the fixing fittings 2a and 2b are integrated, they are formed so as to overlap the surface of the fixing flange portion 22a opposite to the second cable insertion hole 6.

  Further, a thin portion 23 having a thin plate thickness is formed at the distal end portion of the fixing flange portion 22a, and a U-shape is formed at the base end portion of the fixing flange portion 22b in a plan view. An accommodating portion 24 in which the thin portion 23 of 22a is accommodated is formed. The fixing flanges 22a and 22b are formed with screw holes 26 into which the fixing bolts 25 are screwed so as to penetrate the fixing flanges 22a and 22b.

  According to the cable fixing bracket 21, the fixing flange portions 22 a and 22 b do not protrude from the fixing bracket main body 2, so that the entire cable fixing bracket 21 is further downsized, and the wiring space in the portion of the cable fixing bracket 21 is further increased. Can be small.

  The cable fixing bracket 41 shown in FIG. 4 has basically the same configuration as the cable fixing bracket 21 shown in FIGS. 2 and 3. In the one of the divided fixing brackets 2 a (the left side in the figure) obtained by dividing the fixing bracket body 2 into two parts, The partition wall 42 that separates the first cable insertion hole 5 and the second cable insertion hole 6 is made longer than the other split fixing bracket 2b (the right side in the figure), and the first cable insertion hole 5 and the second cable insertion hole 6 are In this case, it is made deeper than the other divided fixture 2b. That is, the cable fixing bracket 41 shifts the dividing position between the first cable insertion hole 5 and the second cable insertion hole 6 in the cable fixing bracket 21 of FIGS. It is a thing.

  In other words, the cable fixing brackets 1 and 21 shown in FIGS. 1 to 3 are partition walls that separate the first cable insertion hole 5 and the second cable insertion hole 6 and divide the fixing bracket main body 2. The inner side surface X (the inner side surfaces of the split fixing brackets 2a and 2b) exposed when the mounting flange portion 3 is split is flush with the inner side surface Y (the inner side surfaces of the split mounting flange portions 3a and 3b) exposed. However, the cable fixing bracket 41 shown in FIG. 4 shows a case where they are not arranged on the same plane.

  According to the cable fixing bracket 41, both of the first cable insertion hole 5 and the second cable insertion hole 6 are divided and fixed in a state where the cable support member 4 and one cable are fitted to the division fixing bracket 2a having the deeper one. Since the metal fittings 2a and 2b can be overlapped, the work for fixing the cable support member 4 and one cable to the fixed metal fitting body 2 can be performed stably, and three cables can be connected to the cable. The work of fixing to the fixing bracket 41 becomes easier. Therefore, the workability | operativity at the time of routing a cable can be improved more.

  The present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit of the present invention.
