In the portion of the wire harness WH that extends from the vehicle body 2 to the door 6, a plurality of electric wires are bundled into one. Moreover, the edge part of the wire harness WH may be appropriately branched according to arrangement | positioning of the electric equipment used as a connection destination.

The door 6 is connected to the vehicle body 2 by door hinges 5 (generally having a pair of door hinges 5, but only one is shown in FIG. 1) so that the entrance / exit formed in the vehicle body 2 can be opened and closed. Yes. The vehicle body 2 refers to a frame portion formed of a metal member. Here, the door 6 is a front side door, and for convenience of explanation, it is assumed that the door 6 is connected to the vehicle body 2 so as to change its posture around an axis along the vertical direction (the rotation axis of the door hinge 5).

The vehicle body 2 and the door 6 are provided with an opening degree restricting section 3 (also referred to as a door check link) for maintaining the door 6 at a predetermined opening degree (full open position, half open position, etc.). More specifically, the opening degree restriction part 3 includes an arm part 3a and a case part 3b. One end of the arm portion 3a (hereinafter referred to as a vehicle body side connecting portion) is connected so as to be relatively rotatable with respect to the vehicle body 2, and a portion thinner than other portions (thin in the vertical direction of the vehicle body) is formed at a plurality of positions in the longitudinal direction. It is formed in a bar shape. In FIG. 1, the thickness of the arm portion 3a is omitted. The case portion 3b is formed in a casing shape having a through-hole through which the arm portion 3a can be inserted, and has a not-shown clamping portion that is pressed and urged so as to sandwich the arm portion 3a. That is, the case portion 3b is likely to stay at a position where the sandwiching portion sandwiches the thin portion with respect to the inserted arm portion 3a. The case portion 3 b is fixed to the door 6 and serves as a door side connecting portion of the opening degree restricting portion 3.

Then, in conjunction with the opening / closing operation of the door 6, the arm portion 3a is relatively inserted and moved with respect to the case portion 3b. In a state where the holding part of the case part 3b is in a position to hold the thin part of the arm part 3a, the posture of the door 6 is maintained unless an external force that can get over the thick part is applied. Generally, the position of the thin portion of the arm portion 3a is set so that the posture of the door 6 can be maintained in the half-open posture and the fully-open posture. The arm portion 3a enters the door 6 with the closing operation of the door 6, and retreats from the door 6 with the opening operation.

The opening restricting portion 3 is generally provided at a position between the pair of door hinges 5 in the vertical direction, that is, at an intermediate portion of the door 6 (excluding the window portion).

The door 6 is provided with a waterproof weather strip 6w along the peripheral edge (see FIGS. 3 and 4). The weather strip 6w is an elastic member formed of rubber or the like that can be in close contact with the opening edge of the entrance / exit of the vehicle body 2 and keep a watertight state inside and outside the vehicle interior with the door 6 closed. And this wiring apparatus 10 becomes a structure which can wire the wire harness WH to the vehicle interior side from the weather strip 6w.

The door 6 includes a door inner panel 7, a door outer panel as an exterior member provided outside the door, and a trim 8 as an interior member attached to the inside of the door inner panel 7 (FIGS. 3 and 4). reference). In general, the door inner panel 7 and the door outer panel are formed of a metal material, and the trim 8 is formed of a synthetic resin material or the like. Moreover, the door 6 is comprised so that the wire harness WH can be inserted in the inside from the front-end part. Here, the wire harness WH can be routed between the door inner panel 7 and the trim 8 through the front opening of the recess 7h of the door inner panel 7 (see FIG. 1). The concave portion 7h is a concave portion that accommodates a protector P, which will be described later. The concave portion 7h opens on the vehicle interior side of the door inner panel 7 and has the front opening.

Further, a hole 2h for inserting the wire harness WH into the vehicle body 2 is formed in the vehicle body 2. The hole 2h is formed in a portion of the opening edge of the entrance / exit that is opposed to the front opening of the recess 7h in the front-rear direction of the vehicle body 2 with the door 6 closed. The front opening and the hole 2h of the recess 7h are hidden by the interior member of the vehicle body 2, the trim 8 of the door 6 and the like when the door 6 is closed.

Here, since the wire harness WH is routed between the vehicle body 2 and the door 6 from the weather strip 6w to the vehicle interior side, the front opening and the hole 2h of the recess 7h are formed from the weather strip 6w. It is formed on the vehicle interior side (see FIGS. 3 and 4).

<Overall configuration of door wiring device>
The overall configuration of the door wiring device 10 will be described. The door wiring device 10 includes the wire harness WH, the exterior member 20, and the protector P.

The exterior member 20 is disposed so as to surround a portion of the wire harness WH that extends from the vehicle body 2 to the door 6. The exterior member 20 functions to protect the wire harness WH from the outside and suppress drooping between the vehicle body 2 and the door 6.

Here, the exterior member 20 is configured such that the annular convex portions 22 and the annular concave portions 24 are alternately and continuously formed along the axial direction. And when external force is applied with respect to the exterior member 20, the exterior part 20 comes to bend easily as a whole because the boundary part of the annular convex part 22 and the annular recessed part 24 mainly elastically deforms easily. Yes. Then, the wire harness WH is inserted into the exterior member 20 to protect the wire harness WH. The exterior member 20 having such a shape is also called a corrugated tube. Such an exterior member 20 is manufactured by extrusion molding and blow molding or vacuum molding of an elastomer such as synthetic resin or synthetic rubber.

Further, the exterior member 20 is formed in a flat cylindrical shape. In order to form the exterior member 20 in a flat cylindrical shape, the cross-sectional view shape of the exterior member 20 may be formed into an ellipse, a rectangle with rounded corners, or the like. Here, the cross-sectional view shape of the exterior member 20 is formed in a shape in which both ends of a pair of semicircular arc shapes are connected by a linear portion. When the exterior member 20 is formed in a flat cylindrical shape as described above, the exterior member 20 can be bent and deformed relatively easily in the minor axis direction, but is relatively difficult to bend and deform in the major axis direction. Therefore, the exterior member 20 is moved along the horizontal plane, and the major axis direction of the exterior member 20 is aligned with the axis (rotation axis of the door hinge 5) along the vertical direction. And the door 6. As a result, the exterior member 20 can bend between the vehicle body 2 and the door 6 following the opening / closing operation of the door 6 in a horizontal plane, and also suppresses drooping between the vehicle body 2 and the door 6. Can support the wire harness WH.

Further, one end of the exterior member 20 is fixed by being wound with a tape T around a portion of the wire harness WH that is routed in the vehicle body 2. An attachment member 30 attached to the vehicle body 2 is fixed to one end portion of the exterior member 20. Further, the other end portion of the exterior member 20 is fixed by being wound with a tape T or the like on a portion of the wire harness WH that is routed in the door 6 (in the guide portion 50 described later), together with the wire harness WH. It can be moved forward and backward in the door 6.

The mounting member 30 (also referred to as an edge protector) is configured to be able to fix a part near one end of the exterior member 20 to the vehicle body 2 (see FIG. 2). The attachment member 30 is fixed to a portion of the exterior member 20 near one end, and is attached to a portion of the vehicle body 2 between the pair of door hinges 5 (see FIGS. 1, 3, and 4). More specifically, the attachment member 30 is configured to be attachable by being pressed against a hole 2 h formed in the vehicle body 2. The attachment member 30 has an insertion part 34, a pressing part 36, and a concave / convex fitting part 38.

The insertion portion 34 is formed in a cylindrical shape that can be inserted into the hole 2h of the vehicle body 2 and in which the exterior member 20 can be disposed inside. Here, the insertion part 34 is inserted toward the front of the vehicle body 2 (hereinafter, the insertion direction S) with respect to the hole 2h. The distal end portion of the insertion portion 34 is provided with a locking portion 35 that can be locked to the peripheral edge portion of the hole portion 2h in a state where the insertion portion 34 is inserted into the hole portion 2h. The locking portions 35 are formed so as to protrude from the circumferential positions of the insertion portion 34 in the circumferential direction (four locations at equal intervals) to the outer peripheral side, and are respectively forward in the insertion direction S with respect to the peripheral portion of the hole 2h. It has a locking surface that can be contacted from the side. More specifically, the locking portion 35 is formed so that the protruding dimension gradually increases from the distal end side to the proximal end side of the insertion portion 34. When each of the locking portions 35 is inserted into the hole 2h, the insertion portion 34 or the locking portion 35 itself is elastically deformed toward the inner peripheral side of the insertion portion 34, and gets over the hole 2h. It is elastically returned to the outer peripheral side at the raised position and locked to the peripheral edge of the hole 2h.

The pressing portion 36 is provided continuously to the proximal end portion of the insertion portion 34, and is formed in a hook shape projecting to the outer peripheral side. The pressing portion 36 can come into surface contact with the peripheral portion of the hole 2h from the rear side in the insertion direction S. That is, the outer peripheral shape of the pressing portion 36 is formed larger than the hole portion 2h.

When the insertion part 34 is inserted into the hole 2h, the locking part 35 is locked from the front side in the insertion direction S with respect to the peripheral part of the hole 2h, and the presser part 36 is the peripheral part of the hole 2h. Is in surface contact from the rear side in the insertion direction S. Thus, the peripheral edge of the hole 2 h is sandwiched between the locking portion 35 and the pressing portion 36, and the attachment member 30 is fixed to the vehicle body 2.

The concave / convex fitting portion 38 is a portion that is positioned so as not to be relatively movable in the extending direction with respect to the exterior member 20 disposed in the insertion portion 34 (and the pressing portion 36). Here, the concave and convex fitting portion 38 is formed in a concave and convex shape corresponding to the concave and convex shape on the outer periphery of the exterior member 20. More specifically, the concave-convex fitting portion 38 has a configuration in which a protrusion along the circumferential direction is formed on the inner peripheral portion of the insertion portion 34. Each protrusion is formed in a width dimension and a height dimension that can be fitted between the annular recesses 24 between the annular protrusions 22 of the exterior member 20. Further, a plurality of ridges are provided in the insertion direction S at intervals corresponding to the annular recess 24 of the exterior member 20.

Moreover, the attachment member 30 is comprised by uniting the member into which the annular member was divided into two. Here, the mounting member 30 is configured by combining J-shaped members (which may be U-shaped members) having different lengths of the facing pieces. Moreover, the uneven | corrugated | grooved part which can mutually fit is formed in each butt | matching part of a pair of substantially J-shaped member, and a pair of substantially J-shaped member is united | combined when these uneven | corrugated parts mutually fit. That is, by sandwiching the exterior member 20 with a pair of substantially J-shaped members, the concave / convex fitting portion 38 is fitted to the outer peripheral portion of the exterior member 20, and the attachment member 30 extends in the extending direction with respect to the exterior member 20. It is attached so that relative movement is impossible. Note that the mounting member 30 preferably has a shape that allows a pair of substantially J-shaped members to be engaged in a non-separable state in a combined state, but the combined state by being fitted into the hole 2h. May be maintained. Further, the attachment member 30 may be connected at one end by a hinge so that a pair of substantially J-shaped members can be opened and closed.

However, the mounting member 30 is not limited to the above shape. For example, the portion for positioning the wire harness WH may be formed in a flat and narrow rectangular shape that protrudes from the proximal end portion of the presser portion 36 toward the rear in the insertion direction S. In other words, the exterior member 20 disposed in the insertion portion 34 (and the presser portion 36) is inserted into the attachment member 30 by fixing the exterior member 20 to the positioning portion by, for example, winding with a tape or a tie band. It can be positioned in direction S. A tie band refers to a member that can adjust and maintain the circumferential dimension of an annular body. When employing such a positioning portion, the attachment member may be integrally formed by injection molding as a whole.

Further, the attachment member 30 is not limited to the resin molded product as described above as long as it can be attached to the vehicle body 2 and the exterior member 20 can be fixed, and may be a grommet formed of an elastomer such as synthetic rubber. Good. Moreover, this attachment member 30 is not necessarily essential and may be omitted.

The protector P is a member for absorbing the surplus length of the wire harness WH while restricting the path of the wire harness WH within the door 6, and includes a guide portion 50 and a storage portion 40 (see FIG. 1).

The guide portion 50 is arranged in a region extending from a portion between the pair of door hinges 5 to the inside of the door 6 in the door 6, and guides a displacement path in a part of the door 6 including the other end portion of the exterior member 20. It is formed in a cylindrical shape or a groove shape. In addition, the accommodating portion 40 is provided in the door 6 so as to be continuous with the guide portion 50. Here, although the accommodating part 40 and the guide part 50 are comprised as an integrally formed component by resin, it is not necessarily required, and the structure united after forming as a separate member may be sufficient. And this accommodating part 40 accommodates the wire harness WH extended from the other edge part of the exterior member 20 in the state which has the allowance space which this wire harness WH can bypass, ie, the state which can absorb extra length. .

A guide port portion 52 into which the other end portion of the exterior member 20 can be inserted is provided at one end portion of the guide portion 50, and the other end portion of the guide portion 50 is continuous with one end portion of the accommodating portion 40. Moreover, the accommodating part 40 has the accommodating space which can accommodate the wire harness WH extended from the other end part of the exterior member 20 inserted in the guide part 50 connected, so that extra length can be absorbed. That is, the accommodation space is a space including a margin space for bypassing the wire harness WH. The accommodating portion 40 has a pull-out port 44 through which the wire harness WH that is inserted into the accommodating space through the guide portion 50 so as to be able to advance and retreat can be drawn into the door 6. That is, the protector P guides the exterior member 20 inserted into the guide portion 50 through the guide port portion 52 toward the accommodation portion 40 and accommodates the wire harness WH extended from the other end portion of the exterior member 20. It is a member that is accommodated in the accommodation space of the portion 40 so as to be able to absorb the surplus length, and extends to the outside, that is, into the door 6 through the outlet 44. The wire harness WH is protected from the peripheral members by the protector P in the door 6. In FIG. 1, a protector P is shown in which the guide port portion 52 and the outlet 44 are opened in a direction substantially orthogonal to each other and are formed in a substantially L shape in front view. Here, the front surface of the protector P (the door wiring device 10) is a surface parallel to the opening direction of the guide port portion 52 (guide direction of the guide portion 50) and the opening direction of the outlet 44. Moreover, if it demonstrates in the state which attached the protector P to the door 6, the surface orthogonal to the direction which connects the vehicle interior and exterior is a front.

Referring to each configuration of the guide unit 50 and the accommodating unit 40, the detailed description will be given.

The guide portion 50 is formed in a cylindrical shape having an internal space in which the exterior member 20 can be disposed so as to be movable back and forth in the extending direction (see FIGS. 1, 3, and 4). More specifically, the guide portion 50 is a cylindrical member having an inner peripheral surface with a cross-sectional shape larger than the cross-sectional shape of the exterior member 20. Then, when the exterior member 20 is inserted into the guide portion 50, the exterior member 20 is guided along the axial direction of the guide portion 50. In other words, the portion including the other end portion of the exterior member 20 is guided so as to be movable along a path connecting the guide port portion 52 that is one end side opening of the guide portion 50 and the accommodating portion 40. Here, the guide portion 50 is a cylindrical member having a D-shaped cross section (see FIG. 7). However, the guide portion 50 only needs to be able to guide the exterior member 20 through insertion, and has a groove shape and a substantially elliptical sectional view. It may be formed in a cylindrical shape such as a shape, a circle, or a polygon other than a rectangle.

Here, the relationship between the guide part 50 and the exterior member 20 will be described. The exterior member 20 is long enough to insert at least a portion including the other end portion into the guide portion 50 when the door 6 is in an open state with one end side portion fixed to the vehicle body 2 via the mounting member 30. The extension dimension is set. On the other hand, the guide unit 50 only needs to be able to regulate the position of the other end portion of the exterior member 20 that is advanced and retracted in the door 6 when the door 6 is opened and closed. In the closed state, the extension dimension is set such that the other end portion of the exterior member 20 protrudes into the housing portion 40. But the guide part 50 is longer than the said dimension, and may be set so that accommodation to the other end part of the exterior member 20 in the closed state of the door 6 is possible.

Further, the guide port portion 52 formed at one end portion of the guide portion 50 may be formed so as to expand to the outer peripheral side (see FIGS. 1, 3, and 4). Here, the guide portion 50 adopts a shape that expands in all directions substantially orthogonal to the extending direction. The guide opening 52 is formed so as to gradually expand toward one end.

The guide portion 50 has at least one guide spring portion 60 that presses the exterior member 20 toward the guide portion 50 while slidably contacting the outer peripheral portion of the exterior member 20. The guide spring portion 60 will be further described later.

The accommodating portion 40 includes a wire harness WH extending from the other end portion of the exterior member 20 between the first route R1 and the second route R2 swelled so that the intermediate portion is separated from the first route R1. It is formed so that it can be accommodated so as to be able to absorb the extra length by bending between them (see FIG. 1).

The housing portion 40 has a first wall portion 41 and a second wall portion 42 that face each other with a housing space in between when viewed from the front. The wire harness WH accommodated in the accommodation space is disposed close to the first wall portion 41 when passing through the first route R1 and close to the second wall portion 42 when passing through the second route R2. . That is, in a state where the wire harness WH passes through the first path R1, there is a margin space on the second wall portion 42 side of the wire harness WH. Each of the first wall portion 41 and the second wall portion 42 is continuous with the other end portion of the guide portion 50, and each other end portion forms a wall portion facing the outlet 44. More specifically, the first wall portion 41 extends so as to connect the other end portion of the guide portion 50 and the outlet 44 of the accommodating portion 40 on the inner peripheral side of the protector P that is substantially L-shaped when viewed from the front. is doing. In addition, the second wall portion 42 is spaced from the first wall portion 41 so that the wire harness WH can be bent and deformed, and is on the outer peripheral side of the substantially L-shaped protector P in the front view, and the other end of the guide portion 50 It extends so as to connect the section and the outlet 44.

The operation of the wire harness WH and the exterior member 20 when the door 6 is opened and closed will be described.

In the open state of the door 6, the other end portion of the exterior member 20 is retracted and positioned in a portion on one end side of the guide portion 50, and the wire harness WH extending from the other end portion of the exterior member 20 is the first It is accommodated in the accommodation space through the route R1 (see FIGS. 1 and 3).

Further, when the door 6 is closed from the open posture, the exterior member 20 moves forward into the guide portion 50, and the wire harness WH extended from the other end is pushed into the housing space and the second wall portion. It is bent so as to be close to 42. And if the door 6 will be in a closed position, the wire harness WH will be in the state accommodated in the accommodation space through 2nd path | route R2 (refer FIG. 1, FIG. 4). That is, compared with the open state of the door 6, the part accommodated in accommodation space among the wire harnesses WH becomes long, and extra length is absorbed.

When the door is opened, contrary to the closing operation, the wire harness WH is pulled out from the accommodation space to the guide portion 50 side, and the portion in the wire harness WH is changed from the second route R2 to the first route R1 side. (See FIGS. 1 and 3).

Returning to the description of the accommodating portion 40, the accommodating portion 40 has an in-door positioning portion 46 to which the wire harness WH can be fixed at the outlet 44. The in-door positioning part 46 is formed in a shape in which the opening edge of the outlet 44 partially extends (see FIG. 1). Then, the wire harness WH drawn through the outlet 44 is in contact with the inside of the in-door positioning portion 46 and is fastened together with a tape T or tie band and fixed (here, fixed with a tape T). ), A part of the wire harness WH can be positioned and fixed in the door 6. Thereby, even if the wire harness WH on the vehicle body 2 side advances or retreats in the housing portion 40 during the opening / closing operation of the door 6, it is possible to prevent the wire harness WH routed in the door 6 from being pulled or loosened. Thus, the extra length can be absorbed in the accommodation space.

The structure for fixing the wire harness WH to the housing portion 40 is not limited to the in-door positioning portion 46, and a plurality of holes for inserting a tie band are formed in the in-door positioning portion extending in a wall shape from the outlet 44. The wire harness WH may be fastened and fixed by inserting the tie band into the hole.

In addition, from a viewpoint of reducing the load added to the wire harness WH, the preferable shape of the accommodating part 40 is as follows. Hereinafter, the shape of the 1st wall part 41 and the 2nd wall part 42 in front view is demonstrated. That is, in the open state of the door 6, the first wall portion 41 has an intermediate portion between the other end portion of the exterior member 20 and the in-door positioning portion 46 in the wire harness WH, and the other end portion of the exterior member 20 and the door. It is formed so that the path can be regulated so as to be accommodated in a path parallel to the direction connecting the inner positioning portion 46. In addition, the second wall portion 42 restricts the wire harness WH from being bent larger than a path passing through a line along the guide direction of the guide portion 50 and a line perpendicular to the guide direction through the door positioning portion 46. It is made possible. Here, the 2nd wall part 42 is formed in the shape where a curved part connects the wall part along the penetration direction of the wall part along the guide direction, and the outlet 44. As shown in FIG. The curved portion is formed so as to bulge by a size smaller than the diameter of the wire harness WH in a direction partially away from the guide portion 50.

However, the accommodating part 40 should just be what accommodates the wire harness WH so that extra length absorption is possible, and is not restricted to the said shape. For example, the shape which has a winding-axis part in accommodation space and can wind and wind the wire harness WH around the said winding-axis part may be sufficient. That is, it is the structure which absorbs surplus length by the winding diameter of the wire harness WH changing within an accommodating part. In addition, although the structure which winds the wire harness WH in this way and absorbs surplus length may be sufficient, when the structure mentioned above which concerns on this embodiment is employ | adopted, surplus length can be absorbed without crossing the wire harness WH, Therefore The thickness dimension can be reduced.

The protector P is accommodated in a recess 7 h formed in the door inner panel 7 in the door 6, that is, between the door inner panel 7 and the trim 8. More specifically, the protector P is formed so as to be fixable to the door inner panel 7 so that it can be disposed in the door 6 in the following posture and position.

The protector P is disposed in the door 6 such that the guide portion 50 is positioned on the front side with respect to the housing portion 40 and extends along the front-rear direction of the door 6, and the outlet 44 faces the upper side of the door 6. ing. Further, the concave portion 7h of the inner panel 7 is formed in a concave shape having an accommodation space in which the protector P can be accommodated entirely or partially in the above posture and at the above position. And the guide port part 52 of the guide part 50 is exposed outside from the door 6 through the opening part ahead of the door 6 among the recessed parts 7h.

As described above, the opening on the front side of the recess 7h and the hole 2h formed in the vehicle body 2 are formed so as to face each other in the front-rear direction of the vehicle body 2 when the door 6 is closed. The attachment member 30 and the protector P are attached to the vehicle body 2 at the position where the attachment member 30 and the guide port portion 52 of the guide portion 50 oppose each other in the front-rear direction of the vehicle body 2 or inside the door 6. Is arranged. More specifically, in the closed state of the door 6, the penetrating direction (insertion direction S) of the attachment member 30 and the extending direction of the guide portion 50 are positioned on a substantially straight line. Thereby, the exterior member 20 inserted through the attachment member 30 and the guide portion 50 and the wire harness WH inside the exterior member 20 extend substantially linearly in the closed state of the door 6.

Here, the protector P has a fixing portion 58 that can be fitted into a hole formed in the bottom portion of the recess 7 h of the door inner panel 7. The fixing portion 58 is formed so as to be able to fit into the hole portion by pressing the protector P in the direction in which the protector P is accommodated in the concave portion 7h. For example, the fixed portion 58 has a base shaft portion that protrudes from the outer surface of the protector P, and a locking portion that is formed so as to expand from the tip portion to the outer peripheral side and elastically deformable on the inner peripheral side. it can. Here, the fixing part 58 is provided in two places so that it may protrude from the guide part 50 and the accommodating part 40 among the outer surfaces on one side of the protector P, respectively. More specifically, the fixed portion 58 is provided on the protector P in a posture in which the guide portion 50 is located on the front side of the accommodating portion 40 and the outlet 44 faces the upper side of the door 6. It protrudes toward the outdoor side.

Then, by inserting the fixing portion 58 into the hole formed in the concave portion 7h, the locking portion comes into contact with the hole and elastically deforms toward the inner peripheral side, and when it exceeds the hole, elastically returns to the outer peripheral side. And it latches from the back side with respect to the peripheral part of a hole. Thus, according to the protector P that can be fixed to the door inner panel 7 by the fixing portion 58, the fixing portion 58 is formed in the recess 7h by bringing the protector P close to the direction in which the protector P is disposed in the recess 7h. Because it is locked in the hole, it can be easily fixed.

Of course, the structure for fixing the protector P to the door inner panel 7 may be arranged in the door 6 in the above posture and position, and other fixing structures may be adopted. For example, the protector P may have a shape that can be fixed to the door inner panel 7 by screwing.

The outlet 44 of the protector P disposed in the door 6 with the above posture and position is located in the upper part of the door 6. Generally, electrical devices such as a switch, a power window motor, a door lock, and a mirror motor mounted in the door are often installed in the upper portion of the door 6. For this reason, the wire harness WH routed in the door 6 is connected to the electrical device through a shorter path.

In addition, from the viewpoint of shortening the path of the wire harness WH in the door 6, the accommodating portion is formed by inclining the outlet (and the entire accommodating portion) toward the installation position (usually rearward) of various electrical devices. Also good.

The protector P having the housing portion 40 and the guide portion 50 can employ, for example, a configuration (not shown) in which a concave member and a lid-like member are combined. And the protector P can be comprised by manufacturing and uniting a concave-shaped member and a lid-shaped member by injection molding etc., respectively. However, the protector P may be formed in a concave shape as a whole and configured so that the opening is closed by the trim 8.

But the accommodating part 40 and the guide part 50 are not restricted to the case where it is formed as a one-part protector P, and the accommodating part 40 separate from the guide part 50 is provided on the other end side of the guide part 50, The exterior member 20 may be guided toward the storage unit 40 by the guide unit 50.

The door wiring device 10 may be assembled before the vehicle is assembled by modularizing the wire harness WH, the exterior member 20, and the protector P that are routed from the vehicle body 2 into the door 6. That is, the wire harness WH is disposed in the exterior member 20, and the other end portion of the exterior member 20 is fixed to the wire harness WH by tape T winding. Further, an attachment member 30 is attached to one end side portion of the exterior member 20 as necessary, and one end portion of the exterior member 20 is fixed by winding the tape T around the wire harness WH, and the other end portion of the exterior member 20 is fixed. Tape T around the wire harness WH and fix it. And the other end side part of the exterior member 20 is arrange | positioned in the guide part 50 of the protector P, the wire harness WH extended from the other end part of the exterior member 20 is arrange | positioned in the accommodating part 40, and the outlet 44 is provided. What is necessary is just to fix the part withdrawn from the tape T around the door positioning part 46.

So far, the door wiring device 10 has been described as being applied between the vehicle body 2 and the door 6 as a front side door, but it can also be applied to a rear side door. In this case, the wire harness WH is bridged between the center pillar (the pillar between the front side door and the rear side door) and the rear side door. That is, a hole is formed in the center pillar, and the attachment member 30 is attached here.

According to the door wiring device 10 configured in this way, the guide portion 50 can guide the displacement path in a part of the door 6 including the other end portion of the exterior member 20 surrounding the wire harness WH, and accommodates it. Since the wire harness WH extending from the other end of the exterior member 20 by the portion 40 is formed so as to be accommodated in a state where the extra length of the wire harness WH can be absorbed, the wire harness WH is accommodated in the door 6. With the opening / closing operation, the door 6 can be smoothly advanced and retracted to absorb the excess length.

Further, since the exterior member 20 is formed in a flat shape and is provided in a flat posture along the vertical direction of the vehicle body 2, the exterior member 20 can be routed in a narrow space in the inside and outside of the door 6 and is disposed in the door 6. The guide part 50 and the accommodating part 40 to be made can also be made flat, and can be applied even in the case of the door 6 in which the space between the door inner panel 7 and the trim 8 is narrow. Further, since the exterior member 20 is provided in a flat posture along the vertical direction of the vehicle body 2, it is relatively difficult to bend in the vertical direction, and the hanging of the wire harness WH can be suppressed.

Moreover, since the wiring device 10 for doors has wired the wire harness WH to the vehicle interior side from the weatherstrip 6w, the member for water-stopping, such as a grommet, is abbreviate | omitted, reduction of a number of parts and an assembly man-hour. Cost reduction and work efficiency can be improved. In addition, according to the structure which does not use a grommet, preparing the cover for preventing a grommet deformation | transformation at the time of transportation and packing can be abbreviate | omitted. It also contributes to theft prevention. Moreover, the expansion work of the grommet at the time of letting the wire harness WH pass can also be abbreviate | omitted compared with the case where it attaches to the door 6 side with a grommet.

Moreover, since the wiring apparatus 10 for doors has wired the wire harness WH between the door inner panel 7 and the trim 8, it was exposed while omitting the trouble of inserting and wiring the wire harness WH through the through hole. Assembling work can be performed in the work space, and assembling performance can be improved and work efficiency can be improved.

<Guide spring part>
The guide spring part 60 provided in the guide part 50 will be described in more detail. 5 is a schematic front view of one end portion of the guide portion 50, FIG. 6 is a schematic plan view of one end portion of the guide portion 50, FIG. FIG. 6 is a schematic explanatory view taken along line VIII-VIII in FIG. 5.

That is, in this embodiment, the guide spring portion 60 is provided in the guide port portion 52 of the guide portion 50. Here, a pair of guide spring portions 60 are provided at positions where the exterior member 20 passing through the guide portion 50 (particularly the guide port portion 52) is sandwiched from above and below, and a pair of guide spring portions are disposed at positions where the exterior member 20 is sandwiched from both sides. 60 is provided. However, the configuration may be such that the pair of guide spring portions 60 is provided at either a position where the exterior member 20 is sandwiched from above or below or a position where the exterior member 20 is sandwiched from both sides. Further, only one guide spring portion 60 or an odd number may be provided. Moreover, the guide spring part 60 may be provided in positions other than up-down or left-right.

The guide spring portion 60 has a guide surface 62 that can slidably contact the outer peripheral surface of the exterior member 20 that passes through the guide portion 50, and the outer peripheral portion of the exterior member 20 that passes through the guide portion 50. It can be pressed against the head (see FIG. 8). The guide surface 62 gradually protrudes toward the inside of the guide portion 50 from the both ends of the guide portion 50 in the insertion direction of the exterior member 20 in the guide portion 50 (also the central axis direction of the guide portion 50). It is formed in a large shape, and can be smoothly slidably contacted with the outer peripheral portion of the exterior member 20 passing through the guide portion 50.

More specifically, the guide spring portion 60 is formed by forming a pair of slits 68 along the central axis direction of the guide portion 50 at the peripheral edge portion of the guide port portion 52 of the guide portion 50. The guide spring portion 60 is integrally connected to the guide portion 50 at the base end portion, and is separated through a pair of slits 68 at both side portions. Therefore, the guide spring portion 60 can be elastically deformed in the inner and outer directions of the guide portion 50 with the base end portion as a support center.

Further, the guide spring portion 60 is formed in a curved plate shape that bulges inside the guide portion 50 while drawing an arc shape from the base end portion toward the tip end portion. Thereby, the guide surface 62 which bulges in an arc shape is formed inside the guide portion 50, and the guide surface 62 can come into contact with the outer peripheral portion of the exterior member 20 passing through the guide portion 50 so as to be smoothly slidable. Yes. When a corrugated tube is used as the exterior member 20, the radius of curvature of the guide surface 62 is set with respect to the width of the annular recess so that the guide surface 62 is not caught by the annular recess formed on the outer peripheral surface of the exterior member 20. It is preferable to make it sufficiently large.

Further, here, the distal end portion of the guide spring portion 60 is curved to be larger than the proximal end portion thereof. In other words, the distal end portion of the guide spring portion 60 warps outward more than the base end portion. Thereby, when the exterior member 20 is inserted into the guide port portion 52, the engagement between the outer peripheral portion of the exterior member 20 and the distal end portion of the guide spring portion 60 is suppressed.

According to the door wiring device 10 in which the guide spring portion 60 is formed, the guide spring portion 60 is pressed against the outer peripheral portion of the exterior member 20 by the guide port portion 52 of the guide portion 50. For this reason, even when the vehicle body 2 vibrates due to running vibration or engine vibration when the vehicle is traveling, or even if the exterior member 20 is shaken between the vehicle body 2 and the door 6 due to opening and closing of the door 6, the guide opening 52 Then, the exterior member 20 is hard to vibrate. For this reason, abnormal noise between the exterior member 20 and the guide port portion 52 is suppressed.

In addition, the guide spring portion 60 has the guide surfaces 62 that gradually increase in the projecting dimension toward the inside of the guide portion 50 from both ends of the guide portion 50 in the insertion direction of the exterior member 20 toward the intermediate portion thereof. The guide surface 62 is not easily caught by the exterior member 20. For this reason, the exterior member 20 can move smoothly in the guide portion 50 (particularly, the guide port portion 52).

Further, it is considered that the wire harness WH and the exterior member 20 are easily shaken and vibrated at a portion spanned between the vehicle body 2 and the door 6. Then, by providing the guide spring part 60 in the guide port part 52, the vibration of the wire harness WH and the exterior member 20 can be effectively suppressed, and abnormal noise can be effectively suppressed.

Further, since the pair of guide spring portions 60 are provided so as to sandwich the exterior member 20 passing through the guide port portion 52, abnormal noise between the exterior member 20 and the guide port portion 52 is more effectively suppressed. be able to.

Further, by suppressing the vibration between the guide port portion 52 and the exterior member 20, it is possible to suppress the wear of both, thereby improving the durability.

Furthermore, in the portion where the guide spring portion 60 is provided, the gap between the guide port portion 52 and the exterior member 20 is closed. For this reason, it is possible to suppress the entry of sand, dust, dust, and the like that try to pass between the guide port portion 52 and the exterior member 20.

{Modifications}
In the above-described embodiment, the example in which the guide spring portion 60 is provided in the guide port portion 52 has been described, but it is not always necessary. 9 and 10, a laterally U-shaped slit 168 is formed in the peripheral wall portion in the middle of the guide portion 150 corresponding to the guide portion 50, and a guide spring is formed in the U-shaped slit 168. The portion 160 may be formed.

The guide spring portion 160 may be connected to the guide portion 150 on either the guide port portion 152 side corresponding to the guide port portion 52 or the opposite side thereof. Here, the slit 168 is oriented sideways so as to open to the opposite side of the guide port portion 152, and thus the guide spring portion 160 is integrally connected to the guide portion 150 on the guide port portion 152 side. The guide spring portion 160 can be elastically deformed in and out of the guide portion 150 with an integral connection portion with the guide portion 150 as a support center.

Further, the guide spring portion 160 is formed in a curved plate shape that bulges inside the guide portion 150 while drawing an arc shape from the base end portion toward the tip end portion. As a result, a guide surface 162 bulging in an arc shape is formed inside the guide portion 150, and the guide surface 162 can come into contact with the outer peripheral portion of the exterior member 20 passing through the guide portion 150 so as to be smoothly slidable. Yes. Note that, similarly to the guide surface 62, it is preferable that the radius of curvature of the guide surface 162 is sufficiently larger than the width of the annular recess of the exterior member 20.

Also in this modified example, the guide spring portion 160 is pressed against the outer peripheral portion of the exterior member 20 in the guide portion 150. For this reason, even if the vehicle body 2 vibrates when the vehicle travels, or the exterior member 20 is shaken between the vehicle body 2 and the door 6 by opening and closing the door 6, the exterior member 20 is unlikely to vibrate in the guide portion 150. . For this reason, the noise between the exterior member 20 and the guide part 150 is suppressed.

In addition, you may use the said guide spring part 60 and the guide spring part 160 together.

Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
