Description

  The present invention relates to a protector for a wire harness.

  Conventionally, a protector for protecting an electric wire of a wire harness has been proposed. This type of protector for a wire harness may not only protect an electric wire but also be used as an attachment portion for attaching the wire harness to a vehicle.

  For example, one of the conventional protectors for wire harnesses (hereinafter referred to as “conventional protector”) constitutes a housing space (tube-shaped housing) for housing an electric wire by the main body and the lid, and the outer wall surface of the main body. A thin plate-like extension piece extending in a direction away from the head. The extension piece is provided with a bolt mounting hole (through hole). When the bolt is fastened to the vehicle body or the like with the bolt (fixing tool) passing through the bolt mounting hole, the wire harness is It is fixed to the vehicle (see, for example, Patent Document 1).

  Hereinafter, for the sake of convenience, the protector for the wire harness is simply referred to as “protector”.

JP 2009-142006 A

  When using a protector as a mounting part for attaching a fixture (bolt, etc.) for fixing the wire harness to the vehicle, in general, from the viewpoint of preventing damage to the protector due to direct contact between the fixture and the protector, An auxiliary component (so-called color or the like) for assisting is provided in the protector. For example, when an auxiliary component is provided in a conventional protector, a ring-shaped resin collar that covers the hole wall surface of the bolt mounting hole (through hole) and its periphery can be used as the auxiliary component. The resin collar is formed, for example, by pressing a resin tube into a bolt mounting hole and then crushing (crimping) both ends of the tube.

  However, in order to provide the auxiliary parts on the conventional protector, apart from the process of attaching the conventional protector to the electric wire of the wire harness (specifically, the process of housing the electric wire in the main body and the process of assembling the lid on the main body). The step of providing the auxiliary component in the bolt mounting hole is required. Further, in some cases, it is necessary to perform the latter process in a dedicated facility different from the facility performing the former process. Therefore, compared with the case where a conventional protector is not used as the attachment portion, the series of steps (and thus the manufacturing process of the wire harness) is complicated by the latter step. Such complexity can be a cause of increasing the manufacturing cost of the wire harness.

  Thus, when using a protector as an attachment part, the manufacturing process of a wire harness becomes complicated and the manufacturing cost of a wire harness may increase. Therefore, from the viewpoint of reducing the manufacturing cost of the wire harness, it is desirable to simplify the manufacturing process of the wire harness as much as possible even when the protector is used as the mounting portion.

  The objective of this invention is providing the protector for wire harnesses which can simplify the manufacturing process of a wire harness as much as possible in view of the said subject.

In order to achieve the above-described object, the wire harness protector according to the present invention has the following features (1) to ( 2 ).
(1) A first member and a second member that form an accommodation space that can accommodate an electric wire of a wire harness, and a holding member that holds the first member and the second member in a state in which the accommodation space is formed in an inseparable manner. A wire harness protector comprising:
The first member is
A first extension piece extending in a direction away from the housing space, the first extension piece having a first through hole penetrating the first extension piece;
The second member is
A second extension piece extending in a direction away from the housing space, the second extension piece provided with a second through hole penetrating the second extension piece;
The holding member is
It is a tubular body having an inner peripheral shape determined so that a fixing tool for fixing the wire harness protector to the vehicle can pass through, and penetrates both the first through hole and the second through hole. wherein the first extension piece and attached to the second extension piece retains said first member and said second member so as,
The first member is
The first extension piece has a tubular first peripheral wall protruding from a peripheral portion including a peripheral edge of the first through hole toward the second extension piece, and the first peripheral wall is inserted into the second through hole. Arranged to be
The holding member is
Enlarging portions that penetrate through the hollow portion of the first peripheral wall and widen away from the first peripheral wall are provided at both ends in the axial direction of the holding member, and the first extension piece and the second extension are formed by the expansion portion. Holding the piece in the axial direction,
The second member is
A tubular second peripheral wall projecting along the first peripheral wall from a peripheral portion including a peripheral edge of the second through hole in the second extension piece;
The first member and the second member are
The first peripheral wall is disposed so as to be inserted into a hollow portion of the second peripheral wall.
The protector for wire harness.
( 2 ) In the protector for wire harnesses as described in said ( 1 ),
One of the first peripheral wall and the second peripheral wall has a locking portion,
The other of the first peripheral wall and the second peripheral wall has a locked portion to which the locking portion is locked,
The protector for wire harness.

  According to the configuration of the above (1), the first member having the first extension piece extending in the direction away from the accommodation space and the second member having the second extension piece extending in the direction away from the accommodation space are respectively extended. It is held inseparable by a holding member attached to the first extension piece and the second extension piece so as to penetrate both of the through holes (first through hole and second through hole) provided in the piece. Furthermore, since this holding member (tubular body) has an inner peripheral shape determined so that a fixing tool for fixing the protector to the vehicle can pass therethrough, the inner side (hollow part) of the holding member is penetrated. If a fixture (bolt, etc.) is attached to the vehicle, the protector can be fixed to the vehicle without directly contacting the first member and the second member (specifically, the first extension piece and the second extension piece). it can. That is, the holding member (tubular body) has both a function of assembling the first member and the second member when the protector is attached to the electric wire, and a function as an auxiliary part for assisting the attachment of the fixture.

  Therefore, when the protector is attached to the electric wire (that is, when the first member and the second member are assembled by the holding member), the auxiliary component (that is, the holding member) is provided on the protector at the same time. In other words, even when the protector is used as an attachment portion for attaching a fixture for fixing the wire harness to the vehicle, it is not necessary to separately perform the step of providing the auxiliary component on the protector.

  Therefore, the wire harness protector of the present invention can simplify the manufacturing process of the wire harness as much as possible.

  The protector for wire harnesses of the present invention has the following effects in addition to the simplification of the manufacturing process described above. For example, in the case of a conventional protector, the main body and the lid are integrated by holding (locking) the convex portion provided on the main body with the concave portion provided on the lid, and the main body and the lid are held. ing. At this time, depending on the dimensional accuracy (variation in shape and the like) of the main body and the lid, there may be a positional shift (rattle) between the main body and the lid. On the other hand, the protector of the present invention has a conventional protector locking structure by devising the shape of the holding member (for example, a shape that is press-fitted into the through-hole and closely contacts the first member and the second member). Compared with increasing dimensional accuracy, rattling between members can be easily prevented.

  Furthermore, since the protector of the present invention does not require the first member and the second member to be provided with a locking structure (convex portion / concave portion) unlike the conventional protector, each member is manufactured (for example, injection molded). The metal mold can be simplified and the manufacturing cost of each member can be reduced.

  In addition, since the protector of the present invention can determine the holding state (for example, whether or not the first member and the second member are securely held) by the presence or absence of the holding member, compared to the conventional protector locking structure. The holding state can be easily and reliably determined. Therefore, insufficient holding (for example, a state in which the convex portion of the conventional protector is in contact with the concave portion but is not completely locked, so-called half-fitting) can be prevented.

  As can be understood from the above description, the “wire harness”, “electric wire”, “vehicle”, and “fixing device” described in the above (1) to (4) are, of course, the protector of the present invention. It does not correspond to the configuration requirements.

  By the way, the 1st member and the 2nd member should just be members which can constitute the storage space which can store the electric wire of a wire harness, and the concrete shape etc. are not restricted in particular. For example, when the accommodation space is configured by a main body and a lid as in the case of a conventional protector, one of the first member and the second member may be formed as the main body and the other may be formed as the lid.

  Furthermore, the specific method by which the holding member holds the first member and the second member via the first through hole and the second through hole is not particularly limited. For example, the holding member can hold the first member and the second member by being press-fitted into the through hole so as to be in contact (contact) with the hole wall surfaces of both through holes. In addition, the holding member has an enlarged portion that extends through the through-hole and extends away from the through-hole at both ends in the axial direction (for example, after attaching the tubular holding member to the through-hole, By caulking, the first member and the second member can be held (clamped).

  The holding member may be designed to have an inner peripheral shape corresponding to the shape, size, type, and the like of the fixture, and the specific shape is not particularly limited. For example, the holding member may have a shape of a circular tube or an elliptical tube (inner cross-sectional shape is circular or oval), or may have a shape of a square tube (inner peripheral cross-sectional shape is polygonal). Good.

Furthermore, according to the configuration of ( 1 ) above, when the protector is attached to the electric wire of the wire harness (that is, the electric wire is accommodated in the accommodating space by the first member and the second member), the first peripheral wall is in the second through hole. By arranging the first member and the second member so as to be inserted, alignment of both through holes (the hollow portion of the first peripheral wall and the second through hole) can be easily performed. Furthermore, this insertion can suppress relative movement between the first extension piece and the second extension piece (movement in a direction perpendicular to the axis of the through hole).

  Furthermore, the holding member penetrates the holding member by passing the first extending piece and the second extending piece in the axial direction by holding the enlarged portions at both ends in the axial direction of the holding member while extending the holding member in the direction away from the peripheral wall. Relative movement (movement in a direction parallel to the axis of the through hole) between the first extension piece and the second extension piece can be suppressed while preventing unintentional removal from the hole (the hollow portion of the first peripheral wall).

  Therefore, the manufacturing process of the wire harness can be further simplified, and the first member and the second member can be more firmly held, and rattling between the members can be further reliably prevented.

  By the way, the specific method in which the holding member is provided with the enlarged portion that spreads away from the peripheral wall is not particularly limited. For example, as a method of forming the enlarged portion, a holding member having one end extended and the other end not extended is used, and after attaching the holding member to the peripheral wall so that one end of the holding member passes through the hollow portion of the peripheral wall, A method of crimping the other end can be used.

  Furthermore, clamping the first extension piece and the second extension piece in the axial direction includes, for example, the surface of the first extension piece (around the peripheral wall) and the surface of the second extension piece (around the through hole). In other words, it is sandwiched so as to press in the thickness direction.

Furthermore, according to the configuration of ( 1 ), not only the tubular peripheral wall is provided on one extension piece (first extension piece), but also the other peripheral piece (second extension piece) is provided with a tubular peripheral wall. It will be. Therefore, compared with the case where a tubular peripheral wall is provided only on one extension piece (first extension piece), the contact area between the peripheral walls (contact area between the outer peripheral surface of the first peripheral wall and the inner peripheral surface of the second peripheral wall) As a result of increasing, rattling between members can be prevented more reliably.

According to the configuration of ( 2 ) above, when the first peripheral wall is inserted into the hollow portion of the second peripheral wall (that is, before the holding member is attached), the locking portion and the locked portion are engaged. Will match. Thereby, prior to holding (final holding) by the holding member, the first member and the second member can be preliminarily held (temporarily held) by the locking portion and the locked portion. That is, apart from the holding member, a mechanism for holding the first member and the second member is provided in the protector.

  Therefore, compared with the case where the first member and the second member are held only by the holding member, the first member and the second member can be held more firmly. Furthermore, the manufacturing process of the wire harness can be further simplified because it is not necessary to consider the detachment of the first member and the second member when attaching the holding member.

  According to this invention, the 1st member and 2nd member which form the accommodation space which can accommodate the electric wire of a wire harness are isolate | separated using the 1st extension piece which has the structure mentioned above, a 2nd extension piece, and a holding member. Can be held impossible. As a result, the manufacturing process of the wire harness can be simplified as much as possible as compared with the conventional protector.

  Furthermore, according to the present invention, rattling between members can be easily prevented as compared with a conventional protector, the manufacturing cost of each member can be reduced, and insufficient holding can be reliably prevented.

  The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through a mode for carrying out the invention described below (hereinafter referred to as “embodiment”) with reference to the accompanying drawings. .

<Configuration of protector>
Hereinafter, the configuration of the wire harness protector 10 (hereinafter referred to as “implementation protector 10”) according to an embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the embodiment protector 10 includes a cover 12 and a base that form a tubular portion 11 (a tubular body having a quadrangular cross section perpendicular to the axis) having a housing space capable of housing the wire W of the wire harness. 13 and a collar 14 that holds the cover 12 and the base 13 in a state in which the accommodation space (tubular portion 11) is formed in an inseparable manner.

  More specifically, as shown in FIG. 2 (AA sectional view of FIG. 1), the cover 12 extends in a direction away from the accommodation space (a direction away from the outer wall surface of the tubular portion 11; right direction in FIG. 2). It has the 1st extension piece 12a, and the base 13 has the 2nd extension piece 13a extended in the direction away from the accommodation space (direction similar to the extension piece 12a). The lower surface of the first extension piece 12a (the surface facing the second extension piece 13a) and the upper surface of the second extension piece 13a (the surface facing the first extension piece 12a) are in close contact with each other.

  The first extension piece 12a is a tubular (circular) first peripheral wall 12b protruding from the surface (lower surface) toward the second extension piece 13a, and radially outward of the first peripheral wall 12b (in other words, The projection 12c protrudes toward the second peripheral wall 13b described later. Both ends of the first peripheral wall 12b in the direction parallel to the axis AX are open ends, and a first through hole (hollow portion) that penetrates the first extension piece 12a is formed. In other words, the first peripheral wall 12b protrudes toward the second extension piece 13a from a peripheral portion including the peripheral edge of the first through hole in the first extension piece 12a.

  More specifically, as shown in FIG. 3, the first peripheral wall 12b provided in the first extension piece 12a has a circular pipe whose height in the direction parallel to the axis AX is larger than the thickness of the second extension piece 13a. It has a shape. The cross section (cross section orthogonal to the axis AX) of the hollow portion of the first peripheral wall 12b is substantially a perfect circle. A plurality of convex portions 12c (three convex portions 12c in this example) are formed on the first peripheral wall 12b so that the distances between the convex portions 12c in the circumferential direction are substantially the same. Notches 12d are provided at both ends in the circumferential direction of the convex portion 12c, and the convex portion 12c is a cantilever beam supported on the lower surface of the first extension piece 12a. Thereby, the convex part 12c can be elastically deformed in the direction orthogonal to the axis AX of the first peripheral wall 12b (the radial direction of the convex part 12c).

  Referring to FIG. 2 again, the second extension piece 13a is engaged with the tubular (circular) second peripheral wall 13b protruding from the surface (lower surface) along the first extension piece 12a and the convex portion 12c. And has a recess 13c. Both ends of the second peripheral wall 13b in the direction parallel to the axis AX are open ends, and a second through hole (hollow portion) that penetrates the second extension piece 13a is formed. In other words, the second peripheral wall 13b protrudes along the first extension piece 12a from a peripheral portion including the peripheral edge of the second through hole in the second extension piece 13a.

  More specifically, as shown in FIG. 3, the second peripheral wall 13b provided in the second extension piece 13a has a height corresponding to the height of the first peripheral wall 12b in the direction parallel to the axis AX. It has a circular pipe shape (the height at which the first peripheral wall 12b can be stored). The cross section of the hollow portion of the second peripheral wall 13b (the cross section orthogonal to the axis AX) is substantially a perfect circle. The second peripheral wall 13b has a plurality of recesses 13c (three recesses 13c in this example) at positions corresponding to the protrusions 12c of the first peripheral wall 12b (that is, the distance between the recesses 13c in the circumferential direction). To be substantially identical). The concave portion 13c is formed by removing a part of the second peripheral wall 13b by a width slightly larger than the circumferential width of the convex portion 12c. As a result, as shown in FIG. 2, the convex portion 12c is locked to the concave portion 13c in a state where the first peripheral wall 12b is inserted into the hollow portion of the second peripheral wall 13b. Therefore, the convex part 12c is also called a latching | locking part, and the recessed part 13c is also called a to-be-latched part.

  The second peripheral wall 13b has a plurality of hooks 13d at predetermined positions between the recesses 13c in the circumferential direction (substantially the center between the recesses 13c). As will be described later (see FIGS. 4 to 6), the hook 13d temporarily fixes the collar 14 when the collar 14 is attached to the first extension piece 12a and the second extension piece 13a. It is a member for preventing unintentional disconnection.

  The hollow portions of the first peripheral wall 12b and the second peripheral wall 13b described above are used for assembling the first extension piece 12a, the second extension piece 13a, and the collar 14. More specifically, as shown in FIG. 2, the first extension piece 12a and the second extension piece 13a are arranged so that the first peripheral wall 12b is inserted into the hollow portion of the second peripheral wall 13b. The collar 14 is disposed so as to penetrate the hollow portion of the first peripheral wall 12b. In order to realize this assembly, the inner peripheral shape (inner diameter) of the first peripheral wall 12b has a size that allows the collar 14 to pass through (that is, the outer peripheral shape of the collar 14 (the outer diameter of the portion excluding both end portions 14a and 14b). Designed to correspond size). Furthermore, the inner peripheral shape (inner diameter) of the second peripheral wall 13b is designed so that the first peripheral wall 12b can be inserted (that is, a size corresponding to the outer peripheral shape (outer diameter) of the first peripheral wall 12b).

  As shown in FIGS. 2 and 3, the collar 14 is a tubular body whose both ends in the direction parallel to the axis AX are open ends, and penetrates the hollow portion of the first peripheral wall 12 b and is separated from the first peripheral wall 12 b. Enlarged portions 14a and 14b extending in the direction are provided at both ends thereof. The enlarged portions 14a and 14b are configured so that the first extension piece 12a and the second extension piece 13a (specifically, the first peripheral wall 12b, the second peripheral wall 13b, and the periphery of these peripheral walls) are parallel to the axis AX of the collar 14. It is pinched. Thereby, the cover 12 and the base 13 in a state where the accommodation space (tubular portion 11) is formed are held inseparable.

  The collar 14 also functions as an auxiliary member for preventing a fixture (for example, a bolt, not shown) for fixing the working protector 10 to a vehicle (not shown) from directly contacting the first extension piece 12a and the second extension piece 13a. To do. In order to realize this function, the inner peripheral shape (inner diameter) of the collar 14 is designed to have a shape (inner diameter) through which the fixture can pass through the working protector 10.

  A plurality of cutouts 14c (three cutouts 14c in this example) are provided on the enlarged portion 14a provided at the lower end of the collar 14 (end on the side close to the second extension piece 13a). It is formed at a position corresponding to the hook 13d of 13b (so that the distance between the notches 14c in the circumferential direction is substantially the same). The notch 14c is a portion where the hook 13d is locked when the above-described temporary fixing (FIGS. 4 to 6) is performed by the hook 13d.

  The above is the description of the configuration of the implementation protector 10.

<How to attach the protector>
Next, a method for attaching the implementation protector 10 to the wire W of the wire harness will be described with reference to FIGS.

  First, as illustrated in FIG. 4A, the electric wire W is accommodated in the accommodating portion 13 e formed at the left end of the base 13 in a state where the cover 12 and the base 13 are separated. At this time, the first peripheral wall 12b provided on the first extension piece 12a and the second peripheral wall 13b provided on the second extension piece 13a are not assembled yet, but are separated.

  Next, as shown in FIG. 4B, the cover 12 is attached to the base 13 so that the opening above the accommodation portion 13 e is covered with the lid portion 12 e of the cover 12. At this time, the first extension piece 12a and the second extension piece 13a are brought into close contact with each other, and the cover 12 and the base 13 are aligned so that the first peripheral wall 12b is inserted into the hollow portion of the second peripheral wall 13b. Done. Thereby, as shown in FIG. 5, the convex part 12c of the 1st surrounding wall 12b is latched by the recessed part 13c of the 2nd surrounding wall 13b. As a result, prior to the final holding by the collar 14 (see FIG. 4D), the cover 12 and the base 13 are preliminarily held (temporarily held). Further, an accommodation space for accommodating the electric wire W is formed between the lid portion 12e and the accommodation portion 13e.

  Next, as shown in FIG. 4C, the collar 14 in which the enlarged portion 14a is formed only at one end (the lower end in the drawing) is attached so as to penetrate the hollow portion of the first peripheral wall 12b. Thereby, as shown in FIG. 6, the hook 13d of the 2nd surrounding wall 13b is latched by the notch 14c of the expansion part 14a. As a result, the collar 14 is temporarily fixed, and the collar 14 is unintentionally detached from the first peripheral wall 12b and the second peripheral wall 13b before being finally held by the collar 14 (see FIG. 4D). Is prevented.

  Finally, as shown in FIG. 4D, the other end (the upper end in the figure) of the collar 14 is crimped by a pressing member or the like (not shown). Thereby, as shown in FIG. 7, an enlarged portion 14 b is formed at the other end (upper end) of the collar 14. As a result, the enlarged portions 14a and 14b at both ends of the collar 14 sandwich the first extension piece 12a and the second extension piece 13a in the axial direction of the collar 14, and the first extension piece 12a and the second extension piece 13a are ( As a result, the cover 12 and the base 13) in a state where the accommodation space is formed are held inseparable.

  The above is description about the method of attaching the implementation protector 10 to the electric wire W of a wire harness.

  As described above, the implementation protector 10 includes the first extension piece 12a, the second extension piece 13a, and the cover 12 and the base 13 that form the accommodation space capable of accommodating the electric wire W of the wire harness. The collar 14 can be used to keep it inseparable. As a result, the manufacturing process of the wire harness can be simplified as much as possible as compared with the conventional protector.

<Other embodiments>
The present invention is not limited to the above embodiment, and various modifications can be employed within the scope of the present invention.

  For example, the implementation protector 10 preliminarily holds the cover 12 and the base 13 by temporarily locking the convex portion 12c provided on the first peripheral wall 12b to the concave portion 13c provided on the second peripheral wall 13b (temporary holding). It is supposed to be. However, the protector of the present invention does not necessarily require such preliminary holding. Specifically, as shown in FIG. 8, the protector of the present invention inserts the first peripheral wall 12 b not having the convex portion 12 c into the second peripheral wall 13 b not having the concave portion 13 c, and the first extension by the collar 14. You may be comprised so that the piece 12a and the 2nd extension piece 13a may be clamped.

  According to the said structure, compared with the implementation protector 10, the manufacturing cost (as a result, manufacturing cost of a wire harness) of the cover 12 and the base 13 can be reduced by the part which can simplify the shape of the 1st surrounding wall 12b and the 2nd surrounding wall 13b.

  Furthermore, the implementation protector 10 forms the through-hole of the 1st extension piece 12a with the 1st surrounding wall 12b, and forms the through-hole of the 2nd extension piece 13a with the 2nd surrounding wall 13b. However, the protector of this invention does not necessarily need to provide a surrounding wall in each extension piece. Specifically, as shown in FIG. 9, the protector of the present invention has a first extension piece 12a that does not have the first peripheral wall 12b (that is, a simple through hole is provided) and a second peripheral wall 13b. The first extension piece 12a and the second extension piece 13a are sandwiched between the collars 14 by arranging the second extension pieces 13a not to be provided (that is, provided with simple through holes) so that the respective through holes correspond to each other. It may be configured as follows. Furthermore, as shown in FIG. 10, the protector of the present invention is configured so that a peripheral wall is provided only in one of the first extension piece 12a and the second extension piece 13a, and the peripheral wall is inserted into a through-hole provided in the other. May be.

  According to the said structure, compared with the implementation protector 10, since the shape of the 1st surrounding wall 12b and the 2nd surrounding wall 13b can be simplified further, the manufacturing cost (as a result, the manufacturing cost of a wire harness) of the cover 12 and the base 13 is further reduced. it can.

  Furthermore, the implementation protector 10 is configured to sandwich the first extension piece 12a and the second extension piece 13a by a collar 14 having enlarged portions 14a and 14b at both ends. However, the protector of the present invention does not necessarily need to be provided with enlarged portions at both ends of the collar 14. Specifically, as shown in FIG. 11, the protector of the present invention presses the collar 14 into the through hole provided in the first extension piece 12a and the through hole provided in the second extension piece 13a. The first extension piece 12a and the second extension piece 13a may be configured to be held inseparable.

  Furthermore, the implementation protector 10 is adapted to bring the first extension piece 12a and the second extension piece 13a into close contact (direct contact). However, the protector of the present invention does not necessarily need to be in direct contact with the first extension piece 12a and the second extension piece 13a, and other members (for example, the gap between the first extension piece 12a and the second extension piece 13a). A rubber or adhesive for preventing rattling) may be sandwiched.

Here, the features of the embodiment of the wire harness protector according to the present invention described above are briefly summarized in the following (1) to (4).
(1) The 1st member (cover 12) and the 2nd member (base 13) which form the storage space which can store the electric wire (W) of a wire harness, and the 1st member (12) in the state where the storage space was formed And a holding member (collar 14) that holds the second member (13) in an inseparable manner, and a wire harness protector comprising:
