  In general, for a wire harness routed in a vehicle or the like, a plurality of optional harnesses are often added to a single main harness. However, the protector described in the said patent document 1 is the structure by which the single holding | maintenance part was connected with respect to the side wall of the protection part which protects a main harness, and cannot hold | maintain a some option harness. If a plurality of optional harnesses are held in this protector, a plurality of holding parts (the fixing part and the holding piece) are separately provided in a part of the side wall of the protection part different from the part to which the holding part is connected. It is necessary to provide, and it is inevitable that the structure of the protector becomes complicated.

  In the protector described in Patent Document 1, the option harness may be detached from the receiving groove of the holding portion due to vibration or the like. In this case, the option harness may repeatedly collide with the fixed portion and the holding portion, thereby possibly damaging the option harness.

  An object of the present invention is to provide a protector capable of holding a plurality of optional harnesses together with a simple structure so as not to be detached from the holding portion.

  As means for solving the problems, the present invention provides a protector for protecting a wire harness including a main harness and an optional harness additionally provided for the main harness, the tube protecting the main harness. A plurality of holding parts having a shape that is open in a specific direction and can hold the optional harness, and a cover that collectively covers the plurality of holding parts, Each of the plurality of holding portions is connected to the outer peripheral surface of the protection portion and is arranged along the circumferential direction of the protection portion, and the cover is configured so that the cover holds the plurality of holding portions together. Blocking provided at a position corresponding to each opening so as to prevent the option harness from being detached from the holding part through the opening of each holding part in the closed posture to cover. To provide a protector having.

  In the present invention, a plurality of holding portions are arranged along the circumferential direction of the protection portion, and the cover has a shape that collectively covers the holding portions, so that a plurality of optional harnesses are held together with a simple structure. It becomes possible to do. In addition, since the cover has a blocking portion provided at a position corresponding to each opening of the holding portion, the cover is open through the opening of each holding portion when the cover is in a closed posture covering the plurality of holding portions at once. The option harness is prevented from being detached from the holding portion.

  In this case, it is preferable that the opening of each holding part is in the same direction in the circumferential direction.

  In this way, since a plurality of option harnesses can be attached to each holding part from the same side in the circumferential direction, work efficiency when attaching these optional harnesses to the holding part is improved. Further, by attaching the option harness to each holding portion in such a posture that the opening of each holding portion faces upward from the horizontal direction, separation (falling) of the option harness from the holding portion during the mounting operation is suppressed.

  Furthermore, in this case, each holding part has a dimension in the circumferential direction of the protection part larger than a dimension in a direction parallel to the thickness direction of the protection part, and a plurality of electric wires included in the optional harness are It is preferable to have a shape that can hold the optional harness in a form that is arranged along the circumferential direction of the protection part.

  In this way, since the optional harness is held in a form in which a plurality of electric wires included in the optional harness are arranged along the circumferential direction of the protective part in a single holding part, the protector is attached to the protective part. The optional harness can be efficiently held while avoiding an increase in size in the thickness direction.

  Further, in the present invention, each holding portion is an end portion of the holding portion opposite to the side connected to the protection portion, and the opening is formed between the end portion and the outer peripheral surface of the protection portion. A front end portion, and the front end portion has a gap smaller than the diameter of the optional harness and is opposed to the outer peripheral surface of the protection portion so that the outer peripheral surface of the protection portion is more than the other portion of the holding portion. And the holding portion is spaced apart from the outer peripheral surface of the protective portion until the gap between the distal end portion and the outer peripheral surface of the protective portion is larger than the diameter of the optional harness. It is preferable to be elastically deformable so as to allow bending and displacement in the direction of movement.

  If it does in this way, at the time of the operation of attaching the option harness to each holding part, the option harness is temporarily held by the holding part in the stage before the cover is brought into the closed posture. Specifically, by applying an external force that displaces the front end portion of the holding portion in a direction away from the outer peripheral surface of the protective portion, the gap between the front end portion and the outer peripheral surface of the protective portion is larger than the diameter of the optional harness. When the optional harness is mounted in the holding portion in a state where the holding portion is elastically deformed until it becomes larger, and then the external force is released, the holding portion is elastically restored, so that the distal end portion of the optional harness is Since it is opposed to the outer peripheral surface of the protection part with a gap smaller than the diameter, the stage before the cover is set to the closed position, that is, the prevention part prevents the option harness from being detached from the holding part. Even if there is no stage, the option harness is held by the holding part in a state in which the separation of the option harness from the holding part is suppressed. Temporarily held) by the. Therefore, the work efficiency when attaching the optional harness to the holding portion is improved.

  Further, in the present invention, each holding portion is an end portion of the holding portion opposite to the side connected to the protection portion, and a tip portion that forms the opening between the end portion and the protection portion Each of the blocking portions is elastically deformable so as to allow it to bend and displace in an approaching direction approaching the outer peripheral surface of the protective portion, and each of the blocking portions has an outer periphery of the protective portion when the cover is in the closed position. You may make it press the said front-end | tip part in the said approach direction so that it may approach a surface and the clearance gap between the said front-end | tip part and the outer peripheral surface of the said protection part is maintained in the state smaller than the diameter of the said optional harness.

  In this way, since the optional harness is restrained in the holding portion when the cover is in the closed posture, the separation of the optional harness from the holding portion is effectively prevented.

  Alternatively, in the present invention, each blocking portion may have a shape that closes the opening while facing the opening of the holding portion in the circumferential direction.

  In this way, the option harness is effectively prevented from being detached from the holding portion with a simple structure.

  Moreover, in this invention, it is preferable to have a through-hole which penetrates the part which the said protection part, the said several holding part, and the said cover have overlapped in the thickness direction of the said protection part.

  In this way, for example, it is possible to mount a main harness having a branch portion. Specifically, the main harness having the branch portion is attached to the protector by leading out the branch portion of the main harness from the through hole.

  In the present invention, the protective part, the plurality of holding parts, and the cover are formed by extrusion so that a cross-sectional shape in a direction orthogonal to the axial direction of the protective part is uniform along the axial direction. It is preferable that

  In this way, the protector can be easily molded simply by cutting the extruded product along the direction orthogonal to the extrusion direction so that the length in the extrusion direction becomes a predetermined dimension.

  As described above, according to the present invention, it is possible to provide a protector capable of holding a plurality of optional harnesses together with a simple structure so that the option harnesses are not detached from the holding portion.

The protrusion 36 has a shape that makes the gap between the protrusion 36 and the outer peripheral surface of the protection part 20 smaller than the diameter of one electric wire included in the option harness WH2. In other words, the protrusion 36 extends from the tip of the second wall portion 34 so as to face the outer peripheral surface of the protection portion 20 with a gap smaller than the diameter of one electric wire included in the optional harness WH2. It protrudes toward the outer peripheral surface of.

  The second wall portion 34 is elastically deformable so as to allow the tip of the second wall portion 34 to bend and displace in the radial direction. More specifically, the second wall portion 34 is until the gap between the protrusion 36 connected to the tip thereof and the outer peripheral surface of the protection portion 20 becomes larger than the diameter of one electric wire included in the optional harness WH2. The protrusion 36 is elastically deformable so as to allow the protrusion 36 to bend and displace in a direction away from the outer peripheral surface of the protective portion 20 (outside of the radial direction), and the protrusion 36 is an outer peripheral surface of the protective portion 20. It can be elastically deformed so as to allow it to bend and displace in the approaching direction.

  The cover 40 has a shape that collectively covers the plurality of holding units 30. The protector 10 according to the present embodiment collects the first cover 40R that collectively covers the three holding portions 30 provided on the outer side of the first main body 22 and the three holding portions 30 provided on the outer side of the second main body 22. And a second cover 40L for covering.

  Each of the covers 40R and 40L can be switched between an open posture (the posture in FIG. 5) that exposes the opening 30a of each holding portion and a closed posture (the posture in FIG. 6) that covers the holding portions 30 collectively. ing. Each of the covers 40R and 40L includes a cover body 42 having a shape that covers the plurality of holding portions 30 from the outside, a flexible hinge portion 44 that connects the cover body 42 and the protection portion 20, and a blocking portion 46.

  One end of the cover main body 42 in the first cover 40 </ b> R is connected to the outer peripheral surface of the first main body 22 via a hinge portion 44. Specifically, the first cover 40R is engaged with the holding portion 30 provided at a position closest to the first engaging portion 22a among the three holding portions 30 provided on the outer side of the first main body 22 and the first engagement. It is connected between the part 22a. A first locked portion 42R having a shape engageable with the first locking portion 23 is formed at the other end portion of the cover main body 42 of the first cover 40R. As FIG. 6 shows, the 1st to-be-latched part 42R and the 1st latching | locking part 23 will mutually engage, and the 1st cover 40R will be in a closed position.

It is connected between the part 24a. A second locked portion 42L having a shape engageable with the second locking portion 25 is formed at the other end portion of the cover main body 42 of the second cover 40L. As FIG. 6 shows, the 2nd to-be-latched part 42L and the 2nd latching | locking part 25 mutually engage, and the 2nd cover 40L will be in a closed position.

  The blocking portion 46 has a shape that protrudes inward from the inner peripheral surface of the cover main body 42. In the present embodiment, the blocking portion 46 is formed on the distal end portion of each second wall portion 34 (the projecting portion 36 in the present embodiment) when the cover main body 42 is in the closed position on the inner peripheral surface of the cover main body 42. It is provided at a position facing the outer surface. As shown in FIG. 6, each blocking portion 46 has the distal end portion of the second wall portion 34 corresponding to the blocking portion 46 inward in the radial direction when the cover main body 42 is in the closed posture (second direction). The tip of the wall 34 is pressed in the approaching direction approaching the outer peripheral surface of the protection unit 20. In this state, the distal end portion of the second wall portion 34 approaches the outer peripheral surface of the protective portion 20, and the gap between the distal end portion and the outer peripheral surface of the protective portion 20 is smaller than the diameter of one electric wire included in the optional harness. Maintained in a state.

  Next, a process of mounting the main harness WH1 and the plurality of optional harnesses WH2 on the protector 10 of the present embodiment will be described.

  First, as shown in FIG. 3, the protective portion 20 is in an open posture in which the engagement between the first engagement portion 22 a of the first main body 22 and the second engagement portion 24 a of the second main body 24 is released. . Then, the main harness WH1 is inserted between both the main bodies 22 and 24. And the protection part 20 is made into a closed attitude | position by engaging the 1st engagement part 22a and the 2nd engagement part 24a mutually. At this time, in the present embodiment, as shown in FIG. 4, the sandwiching portion 28 is elastically deformed so that the distal end portion contacts the inner peripheral surfaces of the main bodies 22 and 24. As shown in FIG. 7, when the diameter of the main harness WH1 is smaller than the inner diameters of the main bodies 22 and 24, the sandwiching portion 28 is elastically deformed so that the tip end portion extends outward in the radial direction. The main harness WH1 is clamped by the elastic return force.

  Subsequently, as shown in FIG. 5, a required number (six in this embodiment) of optional harnesses WH2 is attached to each holding unit 30 according to the vehicle type and grade. Specifically, first, the projecting portion 36 and the protection portion are applied by applying an external force that displaces the distal end portion of the second wall portion 34 radially outward (a separation direction in which the distal end portion is separated from the outer peripheral surface of the protection portion 20). The holding part 30 is elastically deformed until the gap with the outer peripheral surface of 20 becomes larger than the diameter of one electric wire included in the optional harness WH2. In this state, the optional harness WH2 is mounted in the holding portion 30 in a form in which a plurality of (four in this embodiment) electric wires included in the optional harness WH2 are arranged in the circumferential direction through the gap. Thereafter, the external force is released. Then, when the second wall portion 34 of the holding portion 30 is elastically restored, the distal end portion thereof, that is, the protrusion portion 36, has a gap smaller than the diameter of one electric wire included in the optional harness WH2, and the outer periphery of the protective portion 20 Opposite the surface. This step can be achieved by pushing the optional harness WH2 into the holding unit 30 through the opening 30a. Specifically, the optional harness WH2 is brought into contact with the protrusion 36 and the outer peripheral surface of the protection portion 20 in a form in which the electric wires included in the option harness WH2 are arranged in the circumferential direction, and the option harness WH2 is started from this state. Is pushed toward the first wall portion 32. Then, since the second wall portion 34 is elastically deformed so that the gap between the protrusion 36 and the outer peripheral surface of the protection portion 20 is larger than the diameter of one electric wire included in the optional harness WH2, the holding portion is passed through the gap. The option harness WH2 is allowed to enter the vehicle 30. When all the wires included in the optional harness WH2 pass through the protrusion 36, the protrusion 36 faces the outer peripheral surface of the protection portion 20 with a gap smaller than the diameter of one electric wire included in the option harness WH2. As a result, the second wall 34 is elastically restored.

  Therefore, even in the stage before the cover 40 is in the closed position (the stage in FIG. 5), that is, the stage where the blocking part 46 does not prevent the option harness WH2 from being detached from the holding part 30, the option harness WH2 is used. The option harness WH2 is held (temporarily held) by the holding unit 30 in a state where the detachment from the holding unit 30 is suppressed. Therefore, the work efficiency when attaching the optional harness WH2 to the holding unit 30 is improved.

  Thereafter, the first locked portion 42R and the first locking portion 23 are engaged by rotating the cover body 42 of the first cover 40R around the hinge portion 44 of the first cover 40R, and the first By rotating the cover body 42 of the second cover 40L around the hinge portion 44 of the second cover 40L, the second locked portion 42L and the second locking portion 25 are engaged. Thereby, each cover 40R and 40L becomes a closed posture which covers each holding | maintenance part 30 collectively (refer FIG. 6). At this time, in each blocking portion 46, the protrusion 36 approaches the outer peripheral surface of the protection portion 20, and the gap between the protrusion 36 and the outer peripheral surface of the protection portion 20 is larger than the diameter of one electric wire included in the optional harness WH2. Also, the projection 36 is pressed inward in the radial direction (an approaching direction in which the projection 36 approaches the outer peripheral surface of the protection unit 20) so as to be maintained in a small state.

  As described above, in the protector 10 of the present embodiment, the plurality of holding portions 30 are arranged along the circumferential direction of the protective portion 20, and the cover 40 has a shape that covers the holding portions 30 in a lump. A plurality of optional harnesses WH2 can be held together with a simple structure. In addition, when the cover 40 is in a closed posture that covers the holding portions 30 together, the blocking portions 46 press the protrusions 36 inward in the radial direction, so that the optional harness WH2 is placed in the holding portion 30. Be bound. Therefore, the option harness WH2 is effectively prevented from being detached from the holding part 30 through the opening 30a of each holding part.

  Moreover, in this embodiment, since the opening 30a of each holding | maintenance part has the same direction about the said circumferential direction, it mounts | wears with the several option harness WH2 with respect to each holding | maintenance part 30 from the same side of the said circumferential direction. Can do. Therefore, the work efficiency when attaching these optional harnesses WH2 to the holding portion 30 is improved. Further, by attaching the optional harness WH2 to each holding portion 30 with the opening 30a of each holding portion facing upward from the horizontal direction, the separation (falling) of the optional harness WH2 from the holding portion 30 during the mounting operation is suppressed. Is done.

  Furthermore, since each holding | maintenance part 30 has the shape which can hold | maintain the said optional harness WH2 in the form with which the some electric wire contained in the option harness WH2 is located in a line along the said circumferential direction, the said protector 10 is the thickness direction of the protection part 20 It is possible to efficiently hold the option harness WH2 while avoiding an increase in size (in the radial direction).

  Further, in the present embodiment, the protection unit 20, the plurality of holding units 30, and the cover 40 are formed by extrusion molding so that the cross-sectional shape in the direction orthogonal to the axial direction is uniform along the axial direction. Yes. Therefore, the protector 10 can be easily molded simply by cutting the extruded product along a direction orthogonal to the extrusion direction so that the length in the extrusion direction (axial direction) is a predetermined dimension.

  In the present embodiment, the example in which the openings 30a of the holding portions are the same in the circumferential direction is shown. However, as shown in FIG. 8, the openings 30a of the pair of holding portions 30 adjacent to each other are arranged. You may make it oppose the said circumferential direction. In this case, when the cover 40 is in the closed position, the outer side surfaces of both ends are pressed inward in the radial direction by the blocking portions formed between the ends of the second wall portions 34 adjacent to each other in the circumferential direction. May be.

(Second embodiment)
9 and 10 show the configuration of the protector according to the second embodiment of the present invention. In the second embodiment, only the parts different from the first embodiment will be described, and the description of the same structure, operation, and effect as in the first embodiment will be omitted.

  The blocking portion 48 of the present embodiment has a shape that closes the opening 30a while facing the opening 30a of the holding portion in the circumferential direction. Specifically, the blocking portion 48 is located at a position slightly spaced from the tip of the second wall portion 34 in the circumferential direction from the portion of the inner peripheral surface of the cover main body 42 that faces the tip of the second wall portion 34. It has a shape extending inward in the radial direction and facing the opening 30a of each holding portion in the circumferential direction.

  As described above, in this embodiment, the option harness WH2 is effectively prevented from being detached from the holding portion 30 with a simple structure.

  In the present embodiment, the cover 40 is separated from each holding portion 30 in a state where the cover 40 is in the closed position. For this reason, the second wall portion 34 is not elastically deformed in a state where the cover 40 is in the closed position, and the reaction force of the second wall portion 34 is not applied to the cover 40.

  Also in this embodiment, as shown in FIG. 10, the openings 30 a of a pair of holding portions 30 adjacent to each other may be opposed to each other in the circumferential direction. In this case, when the cover 40 is in the closed position, the openings 30a may be closed together by a blocking portion having a shape interposed between the openings 30a adjacent to each other in the circumferential direction.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiment but by the scope of the claims, and includes all modifications within the meaning and scope equivalent to the scope of the claims.

  For example, in the above-described embodiment, an example in which one (bundle) of option harnesses WH2 is held by the single holding unit 30 is shown, but a plurality of option harnesses WH2 are held by the single holding unit 30. May be.

  Further, as shown in FIG. 11, a portion where the protective portion 20, the plurality of holding portions 30 and the cover 40 overlap in the radial direction (in the present embodiment, the approximate center in the axial direction of the protector 10) in the radial direction. A penetrating through hole 10a may be formed. The through hole 10a is formed by punching with a Thomson blade, for example.

  If it does in this way, mounting | wearing of the main harness WH1 which has a branch part will be attained, for example. Specifically, the main harness WH1 having a branch portion is attached to the protector 10 by leading out the branch portion of the main harness WH1 from the through hole 10a.

  Further, the protrusion 36 of the holding unit 30 may be omitted. That is, the gap between the tip of the second wall 34 and the outer peripheral surface of the protection unit 20 in a state where no external force is applied to the second wall 34 and the second wall 34 is not elastically deformed is an optional harness. It may be larger than the diameter of one electric wire included in WH2. In this case, the second wall portion 34 includes a gap between the distal end and the outer peripheral surface of the protection portion 20 in the optional harness WH2 when the outer surface of the distal end is pressed inward in the radial direction by the blocking portion 46. It is comprised so that it may elastically deform so that it may become smaller than the diameter for one electric wire.

  Moreover, although the example which the protection part 20 is cylindrical shape was shown in the said embodiment, if the shape of the protection part 20 can cover the circumference | surroundings of the main harness WH1, it will not be restricted to a cylindrical shape. For example, the protection unit 20 may be a polygonal cylinder such as a square cylinder.

  Moreover, in the said embodiment, although each holding part 30 showed the example which has the 1st wall part 32 and the 2nd wall part 34, the shape of the holding part 30 is not restricted to this. For example, each holding part 30 may have a shape in which one end thereof is connected to the outer peripheral surface of the protection part 20 and is gradually separated from the outer peripheral surface of the protection part 20 from the one end toward the other end (tip).

  Moreover, although the example in which the protector 10 was shape | molded by extrusion molding was shown in the said embodiment, the protector 10 may be shape | molded by injection molding etc.
