It is possible to suppress catching on both ends.

It is a general | schematic whole perspective view of a protector. It is a side view of the extension part for fixation. It is a front view of the extension part for fixation. It is a perspective view which shows the state which fixed the wire harness to the extension part for fixation.

  Hereinafter, the protector 10 which concerns on embodiment is demonstrated (refer FIG. 1, FIG. 4). The protector 10 is a member that covers the wire harness 12 and protects it from the outside along a wiring path. For example, the protector 10 is used to protect the wire harness 12 routed in an automobile or the like from members around the route.

  For convenience of explanation, the wire harness 12 to be protected will be described. The wire harness 12 is formed by bundling one or a plurality of electric wires. The wire harness 12 is usually bundled in an outer peripheral shape having a circular shape in cross section, and here, an example thereof will be described.

  The protector 10 includes a housing part 20 and a fixing extension part 30. And while accommodating the protection object part of the wire harness 12 in the inside of the accommodating part 20, the part extended from the edge part of this accommodating part 20 of the wire harness 12 is a fixing member with respect to the extension part 30 for fixation. Secure with 50.

  The accommodating part 20 is a part which accommodates in the inside with the form which covers the wire harness 12, and protects this wire harness 12 from the outside. Moreover, the accommodating part 20 also fulfill | performs the function which carries out the path | route control of the wire harness 12 accommodated in an inside, and maintains it in a wiring path | route. The housing portion 20 is formed in a shape along the wiring path of the wire harness 12. The accommodating part 20 is formed so that the wire harness 12 can be accommodated, and has a plurality of open end parts for drawing the wire harness 12 to the outside.

  Here, the accommodating part 20 demonstrates in the example currently formed so that accommodation of the part wired along one wiring path | route of the wire harness 12 is possible. But the accommodating part 20 should just be formed in the shape corresponding to the wiring path | route of the wire harness 12, for example, when protecting a branch part, it is good to be formed in the shape corresponding to a branch path.

  More specifically, the accommodating portion 20 is formed in a casing shape having openings through which the wire harness 12 is drawn out at both ends in the direction along the routing path. Moreover, the accommodating part 20 has the bottom part 24 formed flatly in the at least 1 opening end part of the several (here two) opening end parts. Here, the accommodating part 20 shall have the flat bottom part 24 over the whole.

  The accommodating portion 20 is configured by combining the receiving portion 22 and the lid portion 28. The receiving part 22 is formed in a bowl shape that can accommodate the wire harness 12, and has the bottom part 24 on the bottom side thereof. More specifically, the receiving portion 22 is formed in a shape in which a pair of side wall portions are erected on both side edge portions of both side edge portions of the bottom portion 24. The receiving portion 22 is integrally formed with the fixing extension portion 30. The lid portion 28 is a portion formed in a lid shape capable of closing the upper opening of the receiving portion 22.

  And as for the protector 10 as a whole, the synthetic resin material is injection-molded or the like, so that the first member in which the receiving portion 22 and the fixing extension portion 30 are integrated, and the second member that is the lid portion 28. Are formed, and the two members are combined. In addition, the structure which concerns on the unification | combination of a 1st member and a 2nd member can employ | adopt various structures, such as uneven fitting. But the protector 10 is not restricted to the case where the 1st member and 2nd member which were formed separately are united, and can employ | adopt various structures. For example, in the protector, the receiving portion 22 and the lid portion 28 constituting the housing portion 20 may be connected by a hinge.

  The extension part 30 for fixation is a part for fixing the part withdraw | derived from the edge part of the accommodating part 20 of the wire harness 12 (refer FIG. 2, FIG. 3). The fixing extension 30 extends along the bottom 24 from the bottom 24 of the opening end of the housing 20 (see FIG. 2). The fixing extension part 30 includes a main body part 32 and a retaining part 36.

  The main body portion 32 is a portion extending from the bottom portion 24 of the housing portion 20. The main body 32 has a concave surface 33 on the inner peripheral side of the housing portion 20 that gradually becomes deeper in the width direction in the cross-sectional view orthogonal to the extending direction (see FIG. 3). Here, the concave surface 33 is formed in an arc shape in a cross-sectional view orthogonal to the extending direction. Preferably, the radius of curvature of the concave surface 33 is set to be the same as the outer diameter of the wire harness 12 to be protected by the protector 10. Further, here, the concave surface 33 is formed in a shape in which the central portion in the width direction is deepest. That is, the wire harness 12 placed on the concave surface 33 is routed through the center in the width direction of the main body 32. Moreover, the main-body part 32 is formed in the arc-shaped bowl shape in the cross sectional view orthogonal to the extending direction as a whole.

  The main body portion 32 is provided so as to extend from the central portion in the width direction of the bottom portion 24 of the housing portion 20. The central portion in the width direction includes a case where the main body portion 32 slightly deviates from a strict intermediate point in the width direction with respect to the bottom portion 24 due to the shape of the accommodating portion 20, a design error, and the like. That is, it is preferable that the wire harness 12 drawn out from the opening of the accommodating portion 20 is routed along the main body portion 32 so as to pass through an approximate center position without being biased laterally in the width direction of the bottom portion 24.

  Further, the fixing extension portion 30 extends from the inner peripheral surface of the bottom portion 24 of the accommodating portion 20 in a region on the outer peripheral side. That is, the width direction both ends located in the innermost peripheral side of the accommodating part 20 in the main body part 32 are positioned flush with the inner surface of the bottom 24 or on the outer circumferential side (here, flush). Further, the deepest portion of the concave surface 33 is set at a position on the inner peripheral side from the outer surface of the bottom portion 24 of the housing portion 20.

  The wire harness 12 is fixed to the fixing extension part 30 (main body part 32) by a fixing member 50. Here, an example in which an adhesive tape is used as the fixing member 50 will be described. That is, in the state where the wire harness 12 is disposed along the concave surface 33 of the fixing extension 30, the adhesive tape as the fixing member 50 is integrally attached to the wire harness 12 and the fixing extension 30. Wrap and fix. However, the fixing member 50 is not limited to the adhesive tape, and a binding band, a string-like member, a wire, or the like that can be tightened by adjusting the circumference of the ring portion may be adopted.

  The retaining portion 36 is used to prevent the fixing member 50 that bundles the main body portion 32 and the wire harness 12 from falling off from the distal end portion of the main body portion 32 when the wire harness 12 is fixed to the fixing extension portion 30. Part. The retaining portion 36 is formed in a shape that protrudes from the front end portion of the main body portion 32 to both sides. However, the retaining portion 36 may be formed in a shape projecting from the distal end portion of the main body portion 32 to the side opposite to the concave surface 33 or may be omitted.

  Next, the process of setting the wire harness 12 to the protector 10 will be described. First, the wire harness 12 is disposed inside the receiving portion 22 of the housing portion 20.

  Then, a portion of the wire harness 12 that extends from one side of the receiving portion 22 in the wiring direction is disposed on the concave surface 33 of the fixing extension portion 30. Thereby, the part extended from the one side of the receiving part 22 of the wire harness 12 is maintained in the linear path | route through the width direction center part of the bottom part 24. As shown in FIG.

  In this state, the wire harness 12 is fixed to the main body 32 by the fixing member 50. More specifically, the fixing member 50 is wound around the outer periphery of the wire harness 12 and the main body 32 at a position closer to the proximal end than the retaining portion 36 of the main body 32. Thereby, the wire harness 12 is maintained in the path | route which approached the deepest part of the concave surface 33 formed in the arc shape in the cross sectional view orthogonal to the extension direction of the main-body part 32. FIG.

  With the wire harness 12 fixed, the upper opening of the receiving portion 22 is closed by the lid portion 28. That is, the first member and the second member are combined. Thereby, the wire harness 12 is set to a protector (refer FIG. 4).

  According to the protector 10 according to the above-described embodiment, from the flat bottom portion 24 of at least one open end portion of the plurality of open end portions of the accommodating portion 20 formed so as to be capable of being accommodated so as to cover the wire harness 12. The fixing extension portion 30 extending along the bottom portion 24 has a concave surface 33 that gradually becomes deeper in the width direction in the cross-sectional view orthogonal to the extension direction on the inner peripheral side of the housing portion 20. For this reason, by fixing the wire harness 12 by tape winding or the like in a state where the wire harness 12 is placed on the fixing extension portion 30, the wire harness 12 is biased and relatively moved in the width direction with respect to the fixing extension portion 30. The wire harness 12 can be stably fixed with a simpler structure.

  Moreover, since it is a simple structure, the operation | work which fixes the wire harness 12 to the fixing extension part 30 with the fixing member 50 also winds the fixing member 50 integrally on the outer peripheral part of the wire harness 12 and the fixing extension part 30. Just easy. Furthermore, since the structure of the protector 10 itself is simple, the molding die can be made into a simple shape, which contributes to the reduction of the mold cost.

  Moreover, since the wire harness 12 fixed to the extension part 30 for fixation is routed near the deepest part of the concave surface 33, it can respond | correspond to the thing with a several different diameter, and can be fixed stably. .

  Further, the fixing extension portion 30 is formed in a shape in which the concave surface 33 is gradually deepened toward the middle portion in the width direction in a cross-sectional view orthogonal to the extension direction, and therefore, the bending in the direction orthogonal to the extension direction is formed. Strong. Thereby, the part withdraw | derived from the accommodating part 20 of the wire harness 12 can be more reliably maintained on a routing route.

  In addition, since the concave surface 33 of the fixing extension 30 is formed in an arc shape in a cross-sectional view orthogonal to the extending direction, the wire harness 12 to be fixed is routed along the concave surface 33, and the wire harness 12 is It can be fixed more stably.

  Further, since the fixing extension 30 extends from the inner peripheral surface of the bottom portion 24 in the outer peripheral region, the wire harness 12 pulled out from the accommodating portion 20 is hooked at both ends in the width direction of the fixing extension 30. Can be suppressed.

  Moreover, since the extension part 30 for fixation is extended from the center part of the width direction of the bottom parts 24 of the accommodating part 20, wiring the wire harness 12 pulled out from the accommodating part 20 to a routing route more correctly. Can do. Moreover, also in the accommodating part 20, the wire harness 12 can be wired more correctly with respect to the design routing path | route.

  So far, the example has been described in which the main body portion 32 of the fixing extension portion 30 is formed in an arc shape in a cross-sectional view orthogonal to the extension direction. However, the present invention is not limited to this. For example, the concave surface may be formed in a curved shape that gradually becomes deeper toward the middle in the width direction other than a gentle V-shape or arc shape in a cross-sectional view orthogonal to the extending direction of the main body portion. In addition, the main body is not limited to the shape formed in a bowl shape as a whole, only the concave surface is formed in a shape that gradually becomes deeper toward the middle in the width direction, and the opposite side portion is formed in a flat shape. It may be.

  Moreover, although the extension part 30 for fixation has demonstrated in the example extended in the area | region of the outer peripheral side from the internal peripheral surface of the bottom part 24, it is not restricted to this structure. For example, the fixing extension portion 30 has both end portions of the main body portion 32 projecting from the inner peripheral surface of the bottom portion 24 to the inner peripheral side, and the inner peripheral surface of the bottom portion 24 and the deepest portion of the concave surface 33 are flush with each other. It may be set.

  Further, although the example in which the fixing extension 30 extends from the center in the width direction of the bottom 24 has been described, the present invention is not limited to this configuration. That is, it is preferable to determine from which position in the width direction of the bottom portion 24 the fixing extension portion 30 extends according to the routing route of the wire harness 12.

  As mentioned above, although the protector 10 was demonstrated in detail, above-described description is an illustration in all the aspects, Comprising: This invention is not limited to it. The various modifications described above can be applied in combination as long as they do not contradict each other. And it is understood that the countless modification which is not illustrated can be assumed without deviating from the scope of the present invention.
