Description

  The present invention relates to an electric junction box mounted on an automobile and an assembling method thereof.

  When a cover for holding a wire harness or the like is retrofitted to the box body of the electrical junction box, a slide guide for sliding the cover on the box body and the cover is often provided (for example, Patent Document 1). reference).

  As an example of such a slide guide, a combination of convex portions (ribs or the like) and concave portions (grooves or the like) continuously extending in the sliding direction is used. In this case, the slide guides (concave portion and convex portion) combined with each other often have a structure that allows only movement in the sliding direction and does not allow any other movement. Therefore, the slide guide also serves as an engagement means for engaging the two members.

In addition, slide guides that are often used in electrical junction boxes have a structure that is simply a combination of resin-formed concave and convex parts. Yes. If this play is too small, the slide operation cannot be performed smoothly, and if it is too large, the play will increase. Therefore, the play size is set in consideration of the molding quality and the like.

  By the way, when the cover is sticking out from the side of the box body, if a slide guide is provided at the tip of the cover and engaged with the slide guide on the box body side, it becomes a cantilevered support form, The play of the slide guide is a factor in the play of the cover as it is. And the location where the projecting dimension from the box body is large has a greater distance from the slide guide, so that it will be displaced the most when it is loose. Accordingly, a large displacement of the cover due to rattling may cause problems such as the generation of abnormal noise in some cases.

  An object of the present invention is to provide an electrical junction box and an assembling method capable of minimizing the backlash of the cover that protrudes outward in this way.

The invention of claim 1 comprises a box main body that accommodates electrical components and the like, and a cover that is slid and mounted on the side portion of the box main body so as to protrude outside the box main body. In the side part of the box body, a routing groove is formed for fitting a wire harness that is drawn out from the side part of the box body and led out downward from the upper part. A pair of left and right connecting walls projecting in the direction is provided, and the cover is connected to the front wall and both left and right ends of the front wall and overlaps the left and right connecting walls of the box body when mounted on the box body. A horizontal cross-section having a left and right side wall is formed in a substantially U-shape, and a first slide guide for sliding the cover from above is mounted on the front end of the left and right side walls of the cover and the box body, and the connection The cover of the portion where the wall and the left and right side walls overlap In front of the position than the first slide guide as viewed from, and characterized in that a second slide guide for mounting by sliding the cover from above.

  The invention according to claim 2 is the electrical junction box according to claim 1, characterized in that the second slide guide is extended downward from the first slide guide.

  The invention according to claim 3 is the electrical junction box according to claim 1 or 2, wherein the first slide guide and the second slide guide have a large play in the front-rear direction at each inlet, and the back side in the slide direction. It is characterized in that the play in the front-rear direction becomes smaller as it goes to.

  The invention of claim 4 is the electrical junction box according to claim 3, wherein the first slide guide and the second slide guide are respectively connected to the slide groove formed on the box body side and the slide groove. Each inlet is constituted by a pair of convex portions formed on the cover side that fits slidably, and the groove side edge on the inlet side of each slide groove is inclined with respect to the sliding direction of the cover. It is characterized by a large set of play.

The invention of claim 5 is the electric connection box according to any one of claims 1 to 4, after the cover is obtained by arranging the wire harness on the outer surface side of said box body, the upper from a cover which is mounted so as to press the wiring harness, the outer surface side of said box body, for fitting said wire harness derived downwardly from the top is pulled out from the side of the box body An opening groove having a U-shaped cross-section is formed, and the pair of left and right connecting walls are provided on both sides of the installation groove.

The invention of claim 6 comprises a box main body in which electrical components and the like are accommodated, and a cover that is provided by sliding from the upper side to the side of the box main body so as to protrude outside the box main body, On the side of the box body, there is formed a routing groove for fitting a wire harness that is drawn out from the side of the box body and led out downward from the upper part. A pair of left and right connecting walls projecting to the left and right ends of the front wall and the left and right ends of the front wall and overlapping the left and right connecting walls of the box body when mounted on the box body The connecting wall includes a first slide guide for slidably mounting the cover from above on the tip of the left and right side walls of the cover and the box body. The cover where the left and right side walls overlap An assembly method for an electric junction box provided with a second slide guide for sliding and mounting the cover from above at a position closer to the front side than the first slide guide. are drawn out of the wire harness from the side, the drawer was the wire harness, derived toward the top down through between the box pair of left and right connecting walls which project from the side of the body, then, the cover-side While the first slide guide and the second slide guide were engaged with the first slide guide and the second slide guide on the box body side, respectively, the cover was opened to the outside at the lower end side in the initial stage. It is inserted into the box body in an inclined posture so as to be in a state, and at the final stage, the lower end of the cover is guided by the guiding action of the first slide guide and the second slide guide. The inserted while attracted to the box body, wherein the coalescing the cover to the box body.

  According to the first aspect of the present invention, since the slide guides for sliding the cover from above are provided at two positions on the front end side and the front side when viewed from the cover, the backlash of the cover can be reduced.

  When the example is shown using FIG. 9, the play angles θ1 and θ2 of the first and second slide guides, respectively, θ1 is the angle formed by α1 and α2, and θ2 is the angle formed by α3 and α4. In this case, the angle θ formed by the overlapping range α3 and α2 of both play angles becomes the total play angle θ. Therefore, since there are two slide guides, the total play amount can be reduced as a result, and the play of the cover can be reduced.

  In addition, by providing the second slide guide on the front side, the amount of displacement of the lower end of the front wall of the cover that has the largest amount of displacement due to rattling can be reduced. That is, for example, as illustrated in FIG. 7B, when only the first slide guides 12 and 52 on the front end side of the cover 70 are present, the distance L from the front wall lower end K of the cover 70 to the slide guides 12 and 52 is If the angle is the same, the displacement amount of the front wall lower end K of the cover 70 increases. However, in addition to the first slide guides 12 and 52, as shown in FIG. If the second slide guides 14 and 54 are also provided on the side, the distance L is reduced, and accordingly the amount of displacement of the front wall lower end K of the cover 70 can be reduced.

  According to the invention of claim 2, as shown in FIG. 8 (b), the first slide guides 12, 52 are on the upper side, but the second slide guides 14, 54 are on the lower side. Therefore, the backlash of the front wall lower end K of the cover 70 close to the second slide guides 14 and 54 can be further reduced.

  According to the invention of claim 3, the first slide guide and the second slide guide are arranged such that the play in the front-rear direction is large at each entrance and the play in the front-rear direction is reduced toward the far side in the slide direction. Since it is configured, the cover can be easily attached to the box body with a large amount of play at the initial stage of installation, and at the final stage of installation, the cover is placed in the correct final position while gradually removing the play. Can be attached to.

  Therefore, when the wire harness pulled out from the side of the box body is guided downward from the upper part along the outer surface of the box body and further extended in the horizontal direction, the wire harness has a repelling force, Or when the diameter of a wire harness is large, when mounting | wearing with a cover, there exists a possibility that a cover may be inserted, rubbing a wire harness strongly, but the point can be eliminated.

  In other words, at the initial stage of the cover installation, the cover can be mounted on the box body without giving excessive pressing force to the wire harness by providing a great deal of flexibility about the cover posture. As the process proceeds, the restraint performance by the first and second slide guides is exerted strongly, so that the cover can be mounted to the final position while pressing the wire harness from the outside. As a result, the phenomenon that the cover rubs strongly against the wire harness that tends to rebound can be alleviated, and damage to the outer periphery of the wire harness can be prevented. Further, the force when mounting the cover can be reduced.

  In addition, according to the invention of claim 4, it is possible to flexibly reduce the pressing force on the wire harness at the initial stage of the cover mounting by simply providing an inclination to the groove side edge of the entrance portion of the slide groove of the box body. Can be given to the posture of the cover.

  Further, according to the invention of claim 5, since the wiring groove for fitting the wire harness is provided on the outer surface of the side portion of the box body, the wire harness is led out from the upper part through the wiring groove. By attaching a cover thereon, the wire harness can be stably held while suppressing rebound.

  According to the invention of claim 6, in the initial stage, the cover is inserted into the box body in an inclined posture so that the lower end side is opened outward, and in the final stage, the first slide guide and The guide action of the second slide guide allows the cover to be attached to the box body while avoiding rubbing with the wire harness as much as possible. The harness can be securely pressed by the cover.

  Embodiments of the present invention will be described with reference to the drawings.

Is a perspective view of the inner surface of the cover viewed obliquely from below, FIG. 5 is a partially omitted side view showing the combined state of the box body and the cover, and FIG. 6 incorporates a wire harness into the box body. It is a side view of the principal part which shows the state which mounted | wore the cover above.

  The electrical junction box includes a synthetic resin box main body 10 in which electric components and the like are accommodated, and a synthetic resin cover 50 that is mounted on the outer surface of one side of the box main body 10 after the wiring harness is routed. . Each of the box body 10 and the cover 50 is made of an integrally molded product of resin.

  The cover 50 is a slide-type waterproof cover that is provided on the outer surface of the side portion of the box body 10 by sliding from above, and is provided to project outside the box body 10, and the side opening 11 of the box body 10. First slide guides 12 and 52 for guiding the slide operation are provided on the right and left edge portions and the front end left and right of the cover 50.

  The first slide guides 12 and 52 are rail-shaped to be engaged with each other. By assembling the cover 50 from above, the cover 50 is allowed to slide freely in the vertical direction, but in the other direction. The function of restricting the movement of the cover 50 is achieved.

  As the first slide guides 12 and 52, a slide groove 12a is provided on the box body 10 side as shown in FIG. 2, and a slide groove 12a is slidable on the cover 50 side as shown in FIG. A projecting wall (convex portion) 52a that fits in is provided. Further, a rail wall 52b having a U-shaped cross section is provided on the cover 50 side so as to surround the slide guide 12 on the box body 10 side with the protruding wall 52a inserted into the slide groove 12a.

  In this case, as shown in FIG. 2, the groove side edge 12b of the entrance portion (near the upper end) of the slide groove 12a, particularly the back side as viewed from the cover 50, is inclined with respect to the sliding direction of the cover 50. Since the groove width of the slide groove 12a is increased, the play in the front-rear direction of the entrance portion of the first slide guides 12 and 52 between the cover 50 and the box body 10 is set large. Further, the groove width of the slide groove 12a becomes smaller toward the back side (lower side) in the slide direction, and the both side edges of the groove finally become parallel, so that the first gap between the cover 50 and the box main body 10 is increased. The play in the front-rear direction of one slide guide 12, 52 is small.

  Note that the first slide guides 12 and 52 are provided with stoppers (particularly not marked) that restrict the downward movement of the cover 50 when the cover 50 is slid to a fixed position.

  On the outer surface of the lower side of the side opening 11 of the box body 10, a cross-section U-shaped with an open front for fitting a wire harness W drawn from the side opening 11 of the box body 10 and led out downward from the top. Shaped routing grooves 20A, 20B are formed. In this case, two routing grooves 20A and 20B having different cross-sectional areas so as to correspond to the thickness of the wire harness W to be fitted are provided adjacent to each other in parallel.

  In addition, the distal ends (protruding ends) of the left and right side walls 21 and 22 of the routing grooves 20A and 20B projecting from the outer surface of the side portion of the box body 10 to form the routing grooves 20A and 20B are mutually inside. The temporary latching | locking part 23 which regulates the omission of the wire harness W accommodated in the routing grooves 20A and 20B is provided. Here, the temporary locking portion 23 is formed as a tip inclined portion in which the tip edges of the left and right side walls 21 and 22 of the routing grooves 20A and 20B are tilted inward, and the left and right side walls 21 of the routing grooves 20A and 20B. , 22 is provided only in the middle height range.

  Further, the cover 50 has a sealing wall 51 having a width for closing the side opening 11 of the box body 10 at the upper portion, and the horizontal section of the lower half following the sealing wall 51 is formed in a substantially U shape. Is formed of a front wall 70 having a width substantially equal to that of the sealing wall 51 and side walls 71 continuous on both the left and right sides thereof. The front wall 70 has a shape in which two half-cylinder walls according to the curvature of the cross section of the wire harness W are arranged side by side. The upper portion of the front wall 70 is continuous with the lower end of the sealing wall 51 by the inclined wall 74, and a plurality of ribs 78 parallel to the vertical direction are provided on the outer surface of the inclined wall 74 and the sealing wall 51. .

  When the cover 50 is mounted on the box body 10, the cover 50 is inserted outside the left and right side walls 21 and 22 of the routing grooves 20 </ b> A and 20 </ b> B, so that the left and right side walls 21 and 22 are bent outward. Restriction walls 71 and 72 are provided to regulate the above. In this case, the regulation wall 71 of the cover 50 that regulates the bending of the leftmost and rightmost side walls 21 of the left and right side walls 21 and 22 of the two routing grooves 20 </ b> A and 20 </ b> B is configured by the left and right side walls 71 of the cover 50. The other restriction wall 72 is configured by a rib 72 projecting from the inner surface of the cover 50 so as to be inserted into the bending space 25 between the two side walls 22 of the adjacent routing grooves 20A and 20B. Yes.

  Further, the base of the regulation walls 71 and 72 of the cover 50 is provided with an opening preventing portion 73 that prevents the temporary locking portion 23 from opening to the outside by contacting the outside of the temporary locking portion 23. .

  Further, the upper corners 21a, 22a of the left and right side walls 21, 22 of the routing grooves 20A, 20B are cut obliquely or in a curved shape, and the inclined wall 74 of the cover 50 corresponds to the cut shape. .

  A second slide for reinforcing the first slide guides 12 and 52 described above is provided between the outer surface of the outermost side wall 21 of the routing grooves 20A and 20B and the inner surface of the side wall 71 of the cover 50. Guides 14 and 54 are provided.

  When viewed from the cover 50 side, the second slide guides 14 and 54 are located on the front side of the first slide guides 12 and 52 located on the back side, and are located on the inner surface side of the cover 50. A rib (convex portion) 54a provided and a longitudinal slide groove 14a provided on the outer surface side of the outermost side wall 21 of the routing grooves 20A and 20B are formed. Further, the second slide guides 14 and 54 are disposed so as to be parallel to the first slide guide 52 and are provided to extend downward from the first slide guide 52.

  In this case, as shown in FIG. 2, the groove width of the slide groove 14a is increased by the fact that both groove side edges of the entrance portion (near the upper end) of the slide groove 14a are inclined with respect to the sliding direction of the cover 50. Therefore, the play in the front-rear direction of the entrance portion of the second slide guides 14 and 54 between the cover 50 and the box body 10 is set large. In particular, the groove side edge 14b on the near side when viewed from the cover 50 is greatly inclined with respect to the sliding direction of the cover 50, so that even when the cover 50 is inclined, the slide guide 54 on the cover 50 side. The tip of the rib 54a is easily received.

  Further, the width of the groove becomes smaller as the slide groove 14a goes to the back side (lower side) in the sliding direction, and the edges on both sides of the groove are finally made parallel to each other. The play in the front-rear direction of the two slide guides 14, 54 is reduced.

  Further, the outermost side wall 21 of the routing grooves 20A and 20B serves as a connecting wall for supporting the cover 50, and the outer surface of the outermost side wall (connecting wall) 21 and the cover 50 side overlapping therewith. Between the side walls 71, locking mechanisms 30 and 80 for locking the cover 50 in place are provided.

  Next, the operation will be described.

  When assembling this electrical connection box, first, the wire harness W is pulled out from the side portion of the box body 10, and the pulled out wire harness W is led out from the top downward and fitted into the respective routing grooves 20A and 20B. Include. In that case, since the space | interval between the front-end | tips of the temporary latching | locking part 23 is set smaller than the diameter of the wire harness W, when inserting the wire harness W, the side walls 21 and 22 of the routing grooves 20A and 20B are made outside. Insert while bending. When the wire harness W is inserted into the routing grooves 20 </ b> A and 20 </ b> B, the side walls 21 and 22 return to their original positions, and temporary locking by the temporary locking portions 23 is performed in this state. Therefore, the wire harness W does not jump out of the routing grooves 20A and 20B due to rebounding or the like.

  Next, the cover 50 is attached from above. At that time, the slide guides 52 and 54 (the projecting walls 52a and the ribs 54a) on the cover 50 side are engaged with the slide guides 12 and 14 (the slide grooves 12a and 14a) on the box body 10 side, and are slid downward to be locked. The mechanisms 30, 80 are locked together. Thus, the cover 50 can be mounted at a fixed position on the side of the box body 10 simply by sliding the cover 50 from above by the guide action of the slide guides 12, 52, 14, 54. And it can be done smoothly.

  When the cover 50 is mounted in a fixed position, the restriction walls (side walls 71 and ribs 72) of the cover 50 are inserted into the bending space 25 between the outside of the side walls 21 of the routing grooves 20A and 20B and the adjacent side walls 22, and The opening prevention part 73 contacts the outside of the temporary locking part 23. Thereby, the bending to the outer side of the side walls 21 and 22 is regulated by the regulating walls (side walls 71 and ribs 72), and the opening preventing portion 73 prevents the temporary locking portion 23 from opening.

  Therefore, the holding | maintenance with respect to the wire harness W can be made strong and reliable. That is, the holding force of the wire harness W can be increased by realizing the double locking of the locking by the temporary locking portion 23 and the locking by the restriction of the restriction walls (side wall 71 and rib 72).

  In addition, the cover 50 is slid in the direction intersecting the fitting direction of the wire harness W in the routing grooves 20A and 20B by the guides of the first slide guides 12 and 52 and the second slide guides 14 and 54. Therefore, the fear that the cover 50 may be removed by the rebounding force of the wire harness W can be eliminated.

  In addition, since the temporary locking by the temporary locking portion 23 is performed at the stage where the wire harness W is fitted in the routing grooves 20A and 20B, the cover 50 can be easily removed without worrying about the wire harness W rebounding or the like. It can be mounted at a fixed position on the box body 10, and the labor and time can be reduced.

  Further, by fitting the wire harness W in the routing grooves 20A and 20B and attaching the cover 50, the wiring harness W can be routed as shown in FIG. 6 without using extra parts such as clips and protectors. Since the route can be forcibly determined as a route that passes under the obstacle 100, the assembling labor can be reduced and the cost can be reduced.

  Moreover, since the wire harness W can be protected by mounting | wearing with the cover 50, waterproofness can be improved.

  Also, when dismantling, the cover 50 is removed and the wire harness W is pulled out to the front, so it can be easily removed from the routing grooves 20A and 20B, so it is excellent in dismantling and contributes to the reuse of resources. can do.

  Further, since the slide guides 12, 52, 14, and 54 for sliding the cover 50 from above are provided at two positions on the front end side and the front side when viewed from the cover 50, the backlash of the cover 50 can be reduced. it can.

  That is, as shown in FIG. 9, when the play angles θ1 and θ2 of the respective slide guides are set, θ1 is the angle formed by α1 and α2, and θ2 is the angle formed by α3 and α4, both play angles The angle θ formed by the overlapping range α3 and α2 is the total play angle θ. Accordingly, since the total amount of play can be reduced as a result of the presence of the two slide guides 12, 52, 14, and 54, the play of the cover 50 can be reduced.

  Further, by providing the second slide guides 14 and 54 on the front side, the amount of displacement of the lower end of the front wall of the cover 50 that causes the largest amount of displacement due to rattling can be reduced. That is, as shown in FIG. 7, when only the first slide guides 12 and 52 on the front end side of the cover 50 are present, the distance L from the lower end K of the front wall 70 of the cover 50 to the first slide guides 12 and 52 is If the angle is the same, the amount of displacement of the lower end K of the front wall 70 of the cover 50 increases. However, if the second slide guides 14 and 54 are provided on the front side as shown in FIG. Since the distance L is reduced, the amount of displacement of the lower end K of the front wall 70 of the cover 50 can be reduced accordingly.

  Further, the first slide guides 12 and 52 are on the upper side, but the second slide guides 14 and 54 are provided on the lower side thereof, so that the cover 50 close to the second slide guides 14 and 54 is provided. The backlash of the lower end K of the front wall 70 can be further reduced.

  Moreover, in this embodiment, since the temporary latching | locking part 23 is provided only in the height range of the middle stage of the right and left side walls 21 and 22 of the routing grooves 20A and 20B, it is a wire in the upper level and the lower level of the routing grooves 20A and 20B. Regulations on the harness W can be relaxed. Therefore, when the wire harness W is fitted into the routing grooves 20A and 20B from the upper part, the temporary start portion 23 can be smoothly inserted without interfering with the temporary locking portion 23. Temporary locking will be effective for the first time. Also, when the wire harness W is pulled out from the lower part during dismantling, the temporary locking portion 23 does not get in the way at the beginning of pulling out, so that it can be pulled out smoothly and pulled out against temporary locking when it is pulled out to some extent. It will be better.

  Further, since the upper corners 21a, 22a of the left and right side walls 21, 22 of the routing grooves 20A, 20B are cut obliquely or in a curved shape, the electric wire of the wire harness W is hooked on the upper corners 21a, 22a. Without worrying, the wire harness W can be easily inserted into the routing grooves 20A and 20B. Moreover, since the cover 50 is also formed in the shape which has the corresponding inclined wall 74, the wire harness W can be pressed down appropriately.

  Further, in the present embodiment, the first slide guides 12 and 52 and the second slide guides 14 and 54 have a large play in the front-rear direction at each entrance, and the play in the front-rear direction becomes smaller toward the far side in the slide direction. Thus, the cover 50 can be easily attached to the box body 10 while having a large amount of play at the initial stage of attachment, and the cover 50 is fitted while gradually removing play at the final stage of attachment. And can be mounted in the proper final position.

  Accordingly, as shown in FIG. 10 (a), when the wire harness W pulled out from the side of the box body 10 is guided downward from the upper side along the side of the box body 10 and further extended in the horizontal direction. 10A of the wire harness W when the cover 50 is mounted in the direction of arrow A1 from above when the wire harness W has a repelling force or when the diameter of the wire harness W is large. ) There is a concern that it may be inserted while strongly rubbing the range indicated by S, but this point can be solved.

  That is, as shown in FIGS. 10B and 11, in the initial stage of mounting the cover 50, the play of the slide guides 12, 52, 14, 54 is large, so that the flexibility of the posture of the cover 50 can be greatly increased. Accordingly, the cover 50 can be inserted into the box body 10 in a slightly inclined posture so that the lower end side thereof is open to the outside, and the box body 10 can be applied without applying an excessive pressing force to the wire harness W. Can be attached to. At this time, the tip of the rib 54a (second slide guide 54) on the cover 50 side is reliably picked up by the inclination of the groove side edge 14b of the slide groove 14a on the box body 10 side, as shown in FIG. It is inserted into the slide groove 14a.

  Further, as proceeding to the final stage of mounting, as shown in FIGS. 10 (c) and 12, the groove widths of the slide grooves 12a and 14a are reduced to reduce the play in the front-rear direction. Since the restraint performance by the slide guides 12, 52, 14, and 54 is exerted strongly, the lower end side of the cover 50 is attracted to the box body 10 side as indicated by an arrow A3. It is mounted to the final position while pressing down.

  This makes it possible to alleviate the phenomenon that the cover 50 is rubbed strongly against the wire harness W that tends to rebound, and prevents damage to the outer periphery of the wire harness W and when the cover 50 is attached. The cover 50 can be attached to the box body 10 while reducing the force, and the wire harness W can be reliably pressed by the cover 50 at the time of completion of attachment shown in FIG.

  In addition, although the case where two routing grooves 20A and 20B were provided was shown in the said embodiment, one may be sufficient. Three or more routing grooves may be provided.
