  The present invention relates to a protector for protecting, molding, and fixing an electrical component such as a wire harness or an electronic unit and a mounting structure thereof, and more particularly to a protector for an electrical component that is suitably used for a side sill portion of an automobile and a mounting structure thereof.

  Electrical components such as wire harnesses and electronic units installed in automobiles are penetrated through synthetic resin protectors at specified locations to protect, mold, and fix electrical components such as wire harnesses, and this protector is fixed to the vehicle body. By doing so, electrical components such as a wire harness are fixed to the vehicle body. The wire harness protector and the other electrical component protectors are fixed to the vehicle body by inserting a clip provided in the protector into an attachment hole provided in the vehicle body and locking it.

  However, if the clip is formed integrally with the protector and two or more clips are provided at a predetermined interval, an error is likely to occur between the clip and the interval between the mounting holes provided in the vehicle body. The problem that the clip is easily damaged, the mounting is difficult, the position shift after the mounting is likely to occur, the protector is easily damaged, and as a result, the electrical components such as the wire harness cannot be sufficiently protected. There was a problem.

  Therefore, in order to adjust the dimensional error between the mounting hole provided in the vehicle body and the clip provided in the protector, a structure has been proposed in which the clip is formed as a separate part from the protector and retrofitted to the protector body.

  As such a wire harness protector, or a mounting structure thereof, a track portion constituted by a rail is provided in the protector body, a clamp is slidably mounted on the track portion, and a protrusion provided in the clamp and a hole provided in the track portion The structure provided with a clamp stop mechanism formed in (see Patent Document 1), or a protector body having serrated irregularities on the outer peripheral side is held from the outside by a clamp, and the serrated claw of the clamp is secured to the protector body A structure that adjusts the position in the length direction while engaging with the serrated irregularities (see Patent Document 2), a clamp is erected on the elastic band forming the notched ring, and the elastic band is set on the outer periphery of the protector body A structure in which the clamp is slidably movable in the longitudinal direction of the protector main body (see Patent Document 3), and has an engaging portion having sawtooth-like irregularities. The protector body, the clip having an engaging portion that engages with the engagement portion fitted, the structure for adjusting the engagement position of the clip and the protector body (see Patent Document 4.), And the like have been proposed.

  In addition, in order to prevent breakage and disengagement of the fixed portion when the protector is repeatedly contracted and expanded in the longitudinal direction, the protector is constituted by the sub protector having the fixed portion and the main protector inserted into the sub protector. Either one of the protector and the main protector is provided with a strain absorbing portion composed of a protruding portion and a flexible portion protruding from the protruding portion in the longitudinal direction of the protector, and the strain absorbing portion is provided on either the sub protector or the main protector.

  However, in these conventional techniques, when the clip is retrofitted to the protector body as a separate part from the protector body, the clip is rigidly fixed to the protector body, so if a large load is applied to the protector, the clip or There was a problem that the protector body was easily damaged and the durability was low. In particular, in the case of a protector arranged in the side sill portion, this problem is significant because the side sill portion may be stepped on when the vehicle is raised and lowered, and a large stress is applied.

  Furthermore, when the clip (clamp) is a separate part from the protector body, there are problems that the number of parts increases, the installation work becomes complicated, and the manufacturing cost increases. In addition, since the clip is fixed to the protector body later, if the mounting hole of the vehicle body and the position of the clip are misaligned, the position of the clip must be adjusted during assembly of the production line. However, there is a problem that the installation work is complicated and difficult.

  Further, when adjusting the clip position with serrated irregularities, there is a problem that fine position adjustment cannot be performed.

  In addition, after the protector is attached to the vehicle body, the clip is fixed to the protector body rigidly, and the protector is fixed to the vehicle body rigidly, so that when the protector is stressed and distorted, the distortion can be absorbed. However, there was a problem that the protector was easily damaged, the durability was low, and as a result, the wire harness could not be sufficiently protected. In particular, in the case of a protector arranged in the side sill portion, this problem is significant because the side sill portion may be stepped on when the vehicle is raised and lowered, and a large stress is applied.

  Furthermore, in the above-described prior art, the position of the clip can be adjusted only in the longitudinal direction (lateral direction) of the protector, and the position of the protector in the short direction (vertical direction) cannot be adjusted.

  Further, even in the conventional technology provided with the strain absorbing portion, the strain of the protector can be absorbed only in the longitudinal direction of the protector, and there is a problem that the strain in the short direction of the protector cannot be dealt with and the number of parts is reduced. There is a problem that the number of mounting operations becomes complicated and the manufacturing cost increases. In particular, in the case of a protector placed in the side sill part, the side sill part is stepped on when the car is raised and lowered, and a large stress may be applied in the short direction of the protector, and this problem becomes significant because the distortion in the short direction increases. there were.

  Therefore, the present invention solves the above-mentioned problems of the prior art, and in a protector for electrical equipment such as a wire harness and its mounting structure, even if a large load is applied to the protector, the clip or protector as the mounting part is not easily damaged. The purpose is to enhance the durability and sufficiently protect the electrical components such as the wire harness. It is another object of the present invention to reduce the number of parts, facilitate the mounting work, and reduce the manufacturing cost. It is another object of the present invention to facilitate the position adjustment of the clip and facilitate the mounting work. In addition, in the clip position adjustment, the clip position can be finely adjusted, and the position of the protector in the short direction (vertical direction) as well as in the longitudinal direction (horizontal direction) of the protector can be adjusted. Objective. It is another object of the present invention to be able to absorb not only the longitudinal direction of the protector but also the short direction of the protector.

Also became possible. Further, not only the longitudinal direction of the protector but also the short direction distortion of the protector can be absorbed.

  Embodiments of the present invention will be described below with reference to the drawings. A wire harness protector 1 as a protector for an electrical component of the present invention includes a first protector member 2 made of synthetic resin and a second protector member 3 made of synthetic resin attached to a lower opening 29 of the first protector member 2. It is configured. The protector for electrical components in the present invention is not limited to the wire harness protector, but includes various electronic units, for example, protectors for electrical components such as electronic units that need to be fixed to the vehicle body. The present invention will be described by taking, as an example, an embodiment in which a wire harness is used as a protector for an electrical component.

  As shown in FIGS. 1 and 2, the first protector member 2 has a side wall 23 erected from both ends in the short direction of the substantially rectangular upper wall 22, is formed into a bowl shape, and a wire harness as an electrical component A storage portion 20 for storing 10 is surrounded by an upper wall 22 and a side wall 23 and formed in a concave shape.

  One end portion in the longitudinal direction of the first protector member 2 is bent at an upper wall 22 and extends obliquely upward, and an L-shaped fixing piece 221 without one side wall 23 formed at its tip extends. It is installed. Further, the other end portion in the longitudinal direction of the first protector member 2 is bent in a stepped shape with the upper wall 22 facing upward, and one side wall 23 is not formed at the front end portion thereof. A piece 231 is extended. The wire harness 10 is wound with the tape 19 together with the fixing pieces 221 and 231, and is fixed to the first protector member 2 and eventually to the wire harness protector 1.

  A locking claw 33 provided on the second protector member 3 to be described later is locked to the lower ends of the side walls 23, and is used to fix the first protector member 2 and the second protector member 3. Nail receiving portion 25 is provided. The claw receiving portion 25 is provided at a predetermined interval in the longitudinal direction of the first protector member 2, but at a predetermined location, specifically, the root of the end portion of the first protector member 2 bent in a step shape. It is preferable to form the claw receiving portion 250 provided on the base plate wider than the other claw receiving portions 25. With such a configuration, it is possible to reliably perform the locking operation of the locking claw 33 to the claw receiving portion 25.

  Further, when the wire harness protector 1 is attached to the vehicle body 100, a guide rail 4 for locking a clip pedestal 5 to be described later is provided on one side wall 23 facing the upright piece 101 extending in the substantially vertical direction of the vehicle body 100. Depending on the installation position and number of clip bases 5, the side wall 23 is provided to extend in the vertical direction. As shown in FIG. 6, the guide rail 4 is composed of a pair of L-shaped rails 41, 41 extending in the vertical direction of the side wall 23, with the upper sides 411 projecting from each other and facing each other. ing.

  The second protector member 3 is a substantially rectangular flat cover that is attached to the lower opening 29 of the first protector member 2 and closes the lower opening 29. One end of the second protector member 3 is a staircase of the first protector member 2. Corresponding to the end of the shape, it is bent in a staircase shape. Further, the locking piece 31 from which the locking claw 33 inserted and locked to the claw receiving portion 25 provided on the first protector member 2 protrudes from both ends in the short direction of the second protector member 3 is the claw receiving portion 25. Are provided with a predetermined interval in the longitudinal direction corresponding to the installation position and the number of installations.

  Further, a flat locking plate 35 that is locked to the outside of the side wall 23 of the first protector member 2 from both ends in the short direction of the second protector member 3 is provided, and the first protector member 2 and the second protector member 2 are provided. It is preferable to prevent the displacement with the protector member 3 more reliably. Further, the locking plate 35 is preferably provided alternately with the locking pieces 31 in the longitudinal direction of the second protector member 3. This is because by adopting such a configuration, it is possible to achieve a reliable coupling without any deviation between the first protector member 2 and the second protector member 3.

  One end of the second protector member 3 in the short-side direction, when the wire harness protector 1 is attached to the vehicle body 100, on one side end facing the upright piece 101 extending in the substantially vertical direction of the vehicle body 100, A plate-like clip pedestal 5 provided with a clip 50 to be engaged with the engagement hole 107 of the vehicle body 100 at the front end according to the installation position and number of the guide rails 4 provided on the first protector member 2 is a clip pedestal. 5 is integrally formed with the second protector member 3 via a spring portion 6 that allows relative displacement with respect to the wire harness protector 1.

  The spring portion 6 is one end in the short direction of the second protector member 3, and when the wire harness protector 1 is attached to the vehicle body 100, the spring portion 6 is inward from one side end facing the standing piece 101 of the vehicle body 100. The two protectors 3 are formed in the shape of a plate up to the side end of the second protector member 3 between the notches 30, and are substantially flush with the second protector member 3. Is formed. A clip base 5 extends upward from the tip of the spring portion 6.

  As shown well in FIG. 6, the clip pedestal 5 includes a lower piece 51 that extends upward at a substantially right angle from the tip of the spring portion 6, and a middle piece 52 that bends and extends outward from the upper end of the lower piece 51. The clip installation piece 53 is bent again from the upper end of the middle piece 52 and extends upward, and the clip 50 projects from the clip installation piece 53 in the direction opposite to the spring portion 6. From both sides of the lower piece 51, locking blades 57 that are locked to the guide rail 4 provided on the first protector member 2 are projected, and between the lower piece 51 and the middle piece 52, the lower piece 51 and A reinforcing rib 59 is provided to prevent the middle piece 52 from being bent.

  The plate-like spring portion 6 may have a uniform plate thickness, but it should be formed non-uniformly, particularly non-uniformly from the connecting portion with the second protector member 3 toward the tip. Is preferred. By making the plate thickness non-uniform, when the spring portion 6 is displaced, the stress applied to the connection portion between the second protector member 3 and the spring portion 6 and the connection portion between the spring portion 6 and the clip base 5 is concentrated. This is because it can be dispersed, damage to the spring portion 6 can be prevented, and the amount of displacement of the spring can be increased. Specifically, as shown in FIGS. 7 and 8, it is possible to employ a structure in which the spring portion 6 is gradually thinned inwardly from both ends connected to the second protector member 3 and the clip base 5. I can do it.

  As the clip 50, a known industrial fastener can be used. For example, a clip having an arrow shape in a side view in which an elastic locking piece 501 is stretched obliquely rearward from a position opposed to the tip of a support column 502 protruding from the clip base 5 Can be used. When the clip 50 is inserted into the locking hole 107 of the vehicle body 100, the elastic locking piece 501 is bent in the direction of the column 502 and allowed to be inserted into the locking hole 107, and the elastic locking piece 501 is engaged. When passing through the stop hole 107, the elastic locking piece 501 spreads outward from the column 502 due to the spring property of the elastic locking piece 501, and the elastic locking piece 501 is locked to the outer peripheral edge of the locking hole 107.

  In the wire harness protector 1, the clip base 5 is excessively moved downward relative to the first protector member 2 in a state where the first protector member 2 is positioned above the second protector member 3. It is preferable to provide a lock mechanism for regulating the above. By providing such a locking mechanism, it is possible to prevent the spring portion 6 from being excessively displaced and to prevent the spring portion 6 from being damaged.

  The lock mechanism includes a lock claw 55 protruding in a direction opposite to the direction in which the clip 50 protrudes from the lower piece 51 of the clip base 5 and a lock claw provided on the side wall 23 between the rails 411 so as to extend in the same direction as the rail 411. It is comprised by the long hole-like lock hole 27 in which 55 is inserted. As shown in FIG. 7, in a state where the first protector member 2 is positioned on the upper side of the second protector member 3, when the clip base 5 moves downward relative to the first protector member 2, When it moves excessively, the lock claw 55 is locked to the bottom edge 277 of the lock hole 27, and the downward movement of the clip base 5 relative to the first protector member 2 is restricted.

  The lock mechanism is configured as described above if it can restrict excessive movement of the clip pedestal 5 relative to the first protector member 2 in a state where the first protector member 2 is positioned above the second protector member 3. Although not limited and not illustrated, for example, it may be configured by a hole-shaped lock hole provided in the clip base 5 and a lock claw provided on the side wall 23 of the first protector member 2. In this case, the lock claw is locked to the upper edge of the lock hole, and the downward movement of the clip base 5 relative to the first protector member 2 is restricted.

  An insertion recess 237 that allows insertion of the spring portion 6 is provided at the lower end of the side wall 23 between the rails 411 of the first protector member 2. In a state where the first protector member 2 is positioned above the second protector member 3, the spring portion 6 moves up and down in the insertion recess 237, so that the clip base 5 is moved up and down relative to the first protector member 2. It is possible to move.

  Further, the wire harness protector 1 restricts the upward movement of the clip pedestal 5 relative to the first protector member 2 in a state where the first protector member 2 is positioned above the second protector member 3. It is preferable to provide a stopper mechanism. By providing such a stopper mechanism, it is possible to prevent the spring portion 6 from being excessively displaced, and it is possible to prevent the spring portion 6 from being damaged.

  The stopper mechanism is configured by the upper edge of the spring portion 6 and the insertion recess 237. As shown in FIG. 8, in a state where the first protector member 2 is positioned on the upper side of the second protector member 3, when the clip base 5 moves relatively upward with respect to the first protector member 2, When it moves excessively, the spring portion 6 comes into contact with the upper edge of the insertion recess 237, and the upward movement of the clip base 5 relative to the first protector member 2 is restricted.

  The stopper mechanism is configured as described above if it can restrict excessive movement of the clip base 5 relative to the first protector member 2 in a state where the first protector member 2 is positioned above the second protector member 3. Although it is not limited and is not illustrated, for example, the lock claw protruding in the opposite direction to the direction in which the clip 50 protrudes from the lower piece 51 of the clip base 5 and the side wall 23 between the rails 411 extend in the same direction as the rail 411. In this case, the lock claw is engaged with the upper edge of the lock hole, and the first protector member 2 of the clip pedestal 5 is provided. The upward movement relative to is restricted.

  9 to 12, the wire harness protector 1 is attached to the vehicle body 100 with the second protector member 3 facing down, and the wire harness 10 is placed on the inner surface 39 of the second protector member 3. Further, the spring portion 6 is formed substantially flush with the second protector member 3. When the spring portion 6 is moved up and down in such an installation manner, the wire harness 10 also moves up and down each time, and the wiring is displaced, which is not preferable. Moreover, the upward displacement of the spring part 6 is prevented by the wire harness 10, and the upward movement of the clip base 5 relative to the first protector member 2 is prevented. Therefore, the spring part 6 and the wire harness 10 do not interfere and contact so that the wire harness 10 does not disturb the displacement of the spring part 6 and does not displace the wire harness 10 even when the spring part 6 is displaced. Is preferred.

  Therefore, as shown in FIGS. 4, 7 and 8, it is preferable to provide an upwardly projecting rib 37 on the inner surface 39 of the second protector member 3 on which the housed wire harness 10 is placed. The rib 37 may be formed in a height and shape so that the spring portion 6 and the wire harness 10 do not interfere and contact with each other according to the displacement of the spring portion 6. Further, the molding position is not particularly limited, but it is preferable to provide it adjacent to the notch 30 because it can effectively prevent the wire harness 10 from coming into contact with the spring portion 6 due to slack.

  About attachment of the wire harness protector 1 to the side sill portion of the automobile having the vehicle body 100, in particular, the upright piece 101 extending in the substantially vertical direction and the horizontal piece 102 connected to the upright piece 101 and extending in the substantially horizontal direction. explain. First, as shown in FIG. 2, the wire harness 10 is inserted into the storage portion 20 from the lower opening 29 of the first protector member 2, and the wire harness 10 is fixed to the fixing pieces 221 and 231 at both ends of the first protector member 2. At the same time, it is wound with a tape 19 and fixed to the first protector member 2. Then, the locking claw 33 of the second protector member 3 is inserted and locked in the claw receiving portion 25 of the first protector member 2 and the locking plate 35 is locked to the outside of the side wall 23 of the first protector member 2. The second protector member 3 is fixed to the first protector member 2 and the lower opening 29 is closed. At this time, when the locking claw 33 is inserted and locked to the claw receiving portion 25 in order from the end portion of the first protector member 2 bent in a step shape, the first protector member 2 is bent in a step shape. By forming the claw receiving portion 250 provided at the base of the end wider than the other claw receiving portions 25, the locking operation can be performed easily and reliably.

  Simultaneously with the fixing of the second protector member 3 to the first protector member 2, the locking blade 57 of the clip base 5 is slid and inserted into the guide rail 4 of the first protector member 2, that is, between the rails 41 and 41. The clip pedestal 5 is locked to the guide rail 4. Due to this locking, the portion of the clip base 5 inserted into the guide rail 4 is restricted from moving in the direction opposite to the first protector member 2, but the vertical movement of the clip base 5 is not restricted. The guide rail 4 is slidable in the vertical direction.

  Then, as shown in FIG. 9, the clip 50 provided on the clip base 5 is opposed to the standing piece 101 of the vehicle body 100, and the second protector member 3 is opposed to the lateral piece 102 of the vehicle body 100, The clip 50 is inserted and locked in the provided locking hole 107, and the wire harness protector 1 is attached and fixed to the vehicle body 100.

  At the time of this attachment, the positional relationship between the two or more locking holes 107 provided in the vehicle body 100, that is, the difference in distance and height between the locking holes 107, and the two provided in the wire harness protector 1 Even when the positional relationship between the clips 50 described above, that is, the difference in distance and height between the clips 50 is different and an error occurs, the clip 50 is moved via the clip base 5 due to the displacement of the spring portion 6. Can be moved and adjusted easily, and fine adjustments can be made. Further, it is not necessary to adjust the installation position of the clip, and the mounting operation can be facilitated. Moreover, this position adjustment can be performed not only in the longitudinal direction (lateral direction) of the wire harness protector 1 but also in the short direction (vertical direction) of the protector.

  Further, when installing the wire harness protector 1 on the vehicle body 100, as shown in FIG. 11, it is preferable that the horizontal piece 102 of the vehicle body 100 and the second protector member 3, that is, the wire harness protector 1 are separated from each other. With such an attachment structure, as shown in FIG. 12, even when a load is applied from the upper part of the wire harness protector 1, the spring portion 6 is displaced, and the clip pedestal with respect to the first protector member 2. 5 moves relatively upward, the wire harness protector 1 can move downward, the stress applied to the clip 50 as the attachment portion and the wire harness protector 1 can be relieved, and the clip 50 and the wire harness protector 1 Breakage can be prevented.

  Thus, when the wire harness protector 1 is attached to the vehicle body 100 and the clip 50 receives a load in the upward direction as shown in FIG. 8, in other words, a downward load is applied from the upper portion of the first protector member 2. Even if it is a case, the spring part 6 will displace and the clip base 5 will move relatively upwards with respect to the 1st protector member 2, and the load to the clip 50 will be reduced. The movement of the clip base 5 is restricted by a stopper mechanism, that is, when the spring portion 6 abuts on the upper end edge of the insertion recess 237.

  7 and 8, the wire harness 10 is placed on the rib 37, and the spring part 6 and the wire harness 10 do not interfere with or come into contact with each other. Therefore, the wire harness 10 prevents the spring part 6 from being displaced. In addition, as the spring portion 6 moves up and down, the wire harness 10 does not move up and down and the wiring does not shift. In particular, even when the wire harness 10 becomes full in the storage portion 20 of the wire harness protector 1, the same effect can be exhibited.

  As shown in FIG. 7, when the wire harness protector 1 is attached to the vehicle body 100 and the clip 50 receives a load in the downward direction, in other words, an upward load is applied from the lower portion of the first protector member 2. Even in this case, the spring portion 6 is displaced, the clip base 5 is moved downward relative to the first protector member 2, the wire harness protector 1 can be moved upward, and the load on the clip 50 is reduced. In addition, the stress applied to the wire harness protector 1 can be relieved, and damage to the clip 50 and the wire harness protector 1 can be prevented. The movement of the clip pedestal 5 is restricted by a lock mechanism, that is, when the lock claw 55 is engaged with the bottom edge 277 of the lock hole 27.

  As described above, the clip 50 is provided so as to be displaceable with respect to the first protector member 2 due to the spring property of the spring portion 6, and the relative position between the clips 50 can be freely changed. Since the attachment position with respect to is attached so as to be displaceable, even if a load is applied to the wire harness protector 1, the load can be released, and when the protector is stressed and distorted, the strain can be absorbed. It is possible to absorb not only the longitudinal direction of the wire harness protector 1 but also the distortion in the short direction, the clip 50 and the wire harness protector 1 are not damaged, and the wire harness 10 is reliably protected. I can do it.

  Even when the wire harness protector 1 is transported and stored before being attached to the vehicle body 100, the clip base 5 is excessively moved downward relative to the first protector member 2 by the stopper mechanism or the lock mechanism. It can regulate and can prevent breakage of spring part 6, clip base 5, and 2nd protector member 3.

  Further, since the clip 50 is integrally formed with the wire harness protector 1, the number of parts can be reduced, the mounting work can be simplified and facilitated, and the manufacturing cost can be reduced.

  Further, the wire harness protector 1 has a shape in which the upper wall 22 is bent at one end in the longitudinal direction of the first protector member 2 and does not extend obliquely upward, or at the other end, a stepped shape in which the upper wall 22 faces upward. It is good also as selecting and forming suitably the shape which is not bent to (b).

  Further, the wire harness 10 may be fixed to the second protector member 3 instead of being fixed to the first protector member 2.

  In addition to the above-described embodiment, the wire harness protector is not illustrated, but the first protector member 2 is formed in a substantially rectangular flat plate shape, that is, constituted by the upper wall 22, while the second protector member. 3 may be formed in a bowl shape or a concave shape with both side walls extending in the longitudinal direction. The opening of the first protector member 2 in this case means the entire surface where the first protector member 2 faces the second protector member 3.

  In this embodiment, the claw receiving portion 25 and the guide rail 4 are erected in the direction of the second protector member 3 substantially perpendicularly to the upper wall 22 at the side end in the longitudinal direction of the first protector member 2. In addition, a locking piece 31 and a locking plate 35 from which locking claws 33 protrude from the front ends of both side walls of the second protector member 3 are provided, and the spring portion 6 is formed by two notches 30 reaching the side wall front end. The lower piece 51 of the clip pedestal 5 can be formed by the side wall between the two cuts 30.
