Description

  The present invention relates to a splice housing structure for a wire harness for a vehicle, and more particularly, to improve a housing structure for the splice connection portion to the protector when a protector is attached to a wire harness having a plurality of splice connection portions. is there.

  Various structures for accommodating the splice connection portion of the wire harness in the protector have been proposed. For example, in Japanese Patent Application Laid-Open No. 10-271656 (Patent Document 1), as shown in FIG. 11A, the corner 1c of the container 1 such as a protector having a corner 1c composed of a side wall 1a and a bottom wall 1b. The structure which accommodates the splice connection part 2 inside is shown.

  Specifically, as shown in FIG. 11 (B), a lid plate 1e connected to the bottom wall 1b via a hinge 1d so as to be freely opened and closed is provided inside the corner 1c, and the opening and closing ends of the lid plate 1e are It is configured to be fixed to the side wall 1a in a closed state by engaging with a notch 1f formed in the side wall 1a, and after positioning the splice connecting portion 2 at a position where the lid plate 1e is fixed, the lid plate 1e The splice connecting portion 2 is accommodated and fixed in the space inside the corner portion 1c surrounded by the side wall 1a, the bottom wall 1b, and the lid plate 1e.

  However, in the housing structure, it is necessary to divide the electric wire provided with the splice connection part 2 from the group of electric wires for bundling the harness, and to wire it closer to the corner 1c. The operation of positioning the connecting portion 2 at the position where the lid plate 1e is fixed is not easy, and there is a problem in workability. Further, in the housing structure, since the splice connecting portion 2 is located at the bottom of the protector, water easily collects, and it is not possible to completely prevent the splice connecting portion from being wetted, thereby preventing short circuit between splices and infiltration into the harness. Therefore, waterproofing work such as covering the splice connecting portion 2 with silicon is also required.

  In JP-A-11-196523 (Patent Document 2), as shown in FIGS. 12 (A) and 12 (B), the splice connection 3 is sealed and covered with a cap 4 made of an insulating material. An example is shown in which the part 3 is subjected to insulation treatment, and the splice connecting part 3 thus covered with the cap 4 is inserted and fixed in a cap housing chamber 6 formed in the protector 5.

  The cap housing chamber 6 is composed of a space surrounded by a U-shaped protective wall 6a erected from the bottom wall 5a at a position along both side walls 5b of the bowl-shaped protector 5, and has an opening on the upper surface and one end. A rib 6b is provided on the inner surface of the protective wall 6a so as to sandwich both side surfaces of the cap 4.

However, since the housing structure shown in Patent Document 2 requires pretreatment for covering each splice connection portion 3 with a cap 4, the workability is poor and the number of parts is large and the cost is high. There is. Further, since the cap housing chamber 6 is formed at the same height as the bottom wall 5a where water is likely to accumulate when immersed, there is a problem with the waterproof property of the splice connecting portion 3.
Further, since the diameter of the splice connecting portion 3 is also different due to the specification difference, it is necessary to use different caps 4 with different diameters depending on the diameter of each splice connecting portion 3, and the above-mentioned depending on the diameter difference between these caps 4. There is also a problem in that it is necessary to change the internal dimensions of the cap housing chamber 6 or to have a complicated shape that can accommodate various cap diameters.

JP-A-10-271656 JP 11-196523 A

  The present invention has been made in view of the above problems, and eliminates the need for individual insulation / waterproofing work for each splice connecting portion and for separating the splice wires before binding the harness, thereby improving the workability of the wire harness assembly. At the same time, it is an object of the present invention to provide a splice housing structure for a vehicle wire harness that can reduce the number of components and can reduce the cost by enabling to cope with the difference in the diameter of the splice connecting portion due to the specification difference.

In order to solve the above-mentioned problems, the present invention provides a splice housing in which a plurality of splice connecting portions of wires of a wire group constituting a wire harness are housed in a protector made of a resin molded product that penetrates the wire harness. Structure,
The protector includes a protector body having an upper surface opening formed of a bottom wall and both side walls, and a lid for closing the upper surface opening of the protector body,
A plurality of splice accommodating portions having an upper surface opening at a position to be closed by the lid are provided in a projecting manner in series or in parallel with gaps on either or both of the inner and outer surfaces of both side walls of the protector body, The number of splice accommodating portions corresponds to the number of splice connecting portions,
The branch line provided with the splice connecting portion is branched from the trunk line of the wire harness, one splice connecting portion is accommodated in one splice accommodating portion, and the splice connecting portion accommodated in the splice accommodating portion is insulated. A splice housing structure for a vehicle wire harness is provided in which a conductor is exposed and housed without attaching a protective material.

  According to this splice housing structure, since the splice housing portion is provided at the upper part of the both side walls of the protector body, it is possible to prevent the inside of the splice housing portion from being flooded by water that travels along the bottom wall of the protector body. In addition, since the position of the upper surface opening of the splice housing portion is set to the position closed by the lid of the protector body, the upper surface opening of the splice housing portion can be closed at the same time that the protector body is closed by the lid. It is also possible to prevent water from entering the splice container from the inside. Further, since each splice connecting portion can be accommodated one by one in each splice accommodating portion isolated from each other, it is not necessary to perform an insulation process.

  Therefore, by accommodating the splice connection portion in the splice housing portion, an effect equivalent to the case where each of the splice connection portions is individually subjected to insulation treatment and waterproof treatment can be obtained. Insulation / waterproofing work is not required, and workability can be improved. In addition, a conventionally used insulating protective material such as a cap becomes unnecessary, and the number of parts can be reduced, so that the cost can be reduced.

In addition, since the splice housing part is formed on the upper part of the side wall of the protector body, the splice connection part can be housed in the splice housing part after the trunk line is inserted into the protector body. Therefore, it is not necessary to separate the splice wires, which is necessary when fixing to the protector earlier. In addition, since the splice accommodating portions are provided in a distributed manner at a plurality of locations on both side walls of the protector body, it is not necessary to collect the splice wires at a limited wiring position.
Furthermore, the splice connection portions can be easily positioned by accommodating and fixing each splice connection portion in each splice storage portion. Since the trunk line inserted into the protector body is distributed and pressed at a plurality of locations, the wire harness can be easily and reliably positioned. Also from the above points, the workability of the wire harness assembly can be improved.

  Furthermore, since the disconnection of the splice connecting portion from the splice accommodating portion can be regulated by closing the upper surface opening of the splice accommodating portion with the lid, the inner wall of the splice accommodating portion and the splice connecting portion are in contact with or in pressure contact with each other. There is no need, and it is acceptable to have a gap. Therefore, since the splice housing portion has a simple structure, it can flexibly cope with the difference in diameter of the splice connection portion due to the specification difference, and can accommodate and fix splice connection portions of various diameters in the one-size splice housing portion. Further cost reduction can be achieved.

  Further, when the splice housing is formed on the inner surface side of the protector body, the dead space at the upper corner in the bowl-shaped protector body is used, so that the space is limited without interfering with the main line insertion. A large number of splice connection portions can be accommodated at a high density, and the enlargement of the protector and consequently the enlargement of the wire harness diameter can be suppressed.

Each of the splice accommodating portions has a box shape with an opening on the upper surface, a protruding side wall that faces the side wall of the protector body with a space therebetween, a lower holding wall that connects the protruding side wall and the side wall of the protector body, and the splice connection A closed wall on one end side opposed to the distal end side of the part, and a shape provided with an opening for pulling out an electric wire terminal continuous to the splice connecting part facing the closed wall,
And the holding | fitting piece for prevention of an electric wire pull-out which has flexibility protrudes from the upper end of the side wall of the said protector main body by the side of the said electric wire drawer, and the upper end of a protrusion side wall.

By providing the pressing piece for preventing the electric wire from being removed, the splice connecting portion once accommodated in the splice accommodating portion is detached from the upper surface opening until the upper surface opening of the splice accommodating portion is closed by the lid. This can be prevented and workability can be further improved.
Further, since the pressing piece has flexibility, the splice connection portion can be inserted from the upper surface opening of the splice housing portion while pushing down the pressing piece, and the difference in the diameter of the splice connection portion is as follows. Since it can be absorbed by the bending state of the pressing piece, insertion of splice connecting portions with various diameters is allowed, and disconnection can be restricted by elastic restoration.

It is preferable that a drain opening is provided on the lower holding wall side of each splice housing portion.
Thereby, even when water enters the splice housing portion, the flooded state can be prevented from continuing for a long time, so that the splice connection portion can be prevented from corroding.

While the splice container provided adjacent to the same side wall of the protector body with a gap, the opening for drawing out the electric wire terminal is provided oppositely,
A branch line having a splice connection portion at a terminal branched from the trunk line is bundled as a set of two branch lines, branched at the terminal side, and each splice connection portion is connected to the adjacent splice housing portion. You may distribute and accommodate.

  In this way, two splicing wires are bundled together as a set, and two splice accommodating portions are also set as one pair, and the splicing connecting portions are accommodated in the splice accommodating portions by providing the respective wire terminal lead-out circular openings facing each other. In doing so, the two splice connecting portions at the end of the branch line bundled in a set can be simultaneously inserted into the two splice accommodating portions at the same time, and workability can be further improved.

The splice accommodating portion is also provided on the opposite side wall of the protector body so as to face the opening for pulling out the end of the electric wire. The four branch lines are pulled out as a set, and the four branch lines are set as two sets on both sides. It is preferable that the splice connecting portion of each branch line terminal is accommodated in the splice accommodating portion after being distributed to the side wall.
As described above, the splice housing portion is provided in series on the side wall of the protector body, the splice housing portion is provided in parallel on the opposite left and right side walls, and the branch line provided with the splice connection portion on the terminal is connected in the front-rear serial direction and the left-right parallel direction. By allocating to, the splice connection can be held tightly by the protector.

The lid is provided continuously on the upper end of one side wall of the protector body via a thin hinge portion, or when the splice housing portion protrudes from the outer surface of the side wall, the protruding side walls of these splice housing portions are provided. The lid is continuously provided at the upper end via a thin hinge portion, and the upper surface opening of the splice housing portion is closed by the lid.
The lid is not limited to being provided integrally with the protector body via the thin hinge, and may be attached to the protector body as a separate body so as to close the upper surface opening of the splice housing.

  As described above, according to the present invention, by forming the splice housing portion on the upper portion of the side wall of the protector body, it is possible to prevent water from entering the splice housing portion along the bottom surface of the protector body, and Since the upper surface opening of the splice housing part is closed with a lid, it is possible to prevent water from entering from the upper surface opening. Therefore, by accommodating the splice connection part in the splice housing part, water intrusion into the splice connection part can be prevented. It can prevent and serve as waterproof treatment. Moreover, since each splice accommodating part is provided apart, it can serve as the insulation process of a splice connection part by accommodating one splice connection part in each splice accommodation part. Therefore, since it is not necessary to perform insulation treatment or waterproof treatment in advance on the splice connection portion, man-hours can be reduced and parts such as caps can be reduced, thereby improving workability and reducing costs.

  Furthermore, since the splice connecting portion is only accommodated in the splice accommodating portion of the splice connecting portion, the splice connecting portion can be easily positioned, and the protector is provided by dispersing the splice accommodating portions at a plurality of positions on the inner surface side of the protector body. The harness inserted into the harness can be pressed at a plurality of locations by the splice housing portion, and the harness can be positioned easily and reliably.

  Furthermore, since a plurality of the splice housing portions are provided on the upper side walls of the protector body, the splice connection portion can be housed in the splice housing portion after the harness is first inserted into the protector body. There is no need to separate the wires in advance or to collect them at a limited wiring position.

  Furthermore, since the splice housing portion regulates the slippage of the splice connecting portion by a lid that closes the upper surface opening, the inner wall of the splice housing portion does not need to be in contact with or in pressure contact with the splice connecting portion, and has an easy structure. Although it is possible to accommodate and fix splice connecting portions having different diameters, the cost can be further reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Tapes 15 with the trunk line 11 are wound around the lead portions of the branch lines 13A and 13B, and the position of the branch line 13 is fixed.
Further, as shown in FIG. 1 (B), the branch line 13 that is distributed in the front-rear direction is bundled with the two branch lines 13A and 13B as a set and wound with the tape 15 around the branch base side, while the terminal side is You may make it bifurcate without binding.
In addition, as shown in FIG. 1C, the four branch lines 13 provided with the splice portions 14 may be branched from the same portion of the trunk line 11 and positioned in the front-rear and left-right directions by the tape 15.

As shown in FIG. 2, the protector 20 includes a protector body 21 having an upper surface opening made up of a bottom wall 23 and left and right side walls 24, and a lid 22 that closes the upper surface opening of the protector body 21. The lid 22 is continuously and integrally provided at the upper end 24a of one side wall 24 of the protector body 21 via a thin hinge portion 26 so as to be opened and closed.
A locking claw 27 is provided on the lid 22 so as to protrude downward from the opening / closing end 22a, and a locked frame for inserting and locking the locking claw 27 on the outer surface of the lid opening / closing side wall 24 of the protector body 21. A portion 28 is projected.

  The space surrounded by the left and right side walls 24 and the bottom wall 23 of the protector body 21 is a trunk insertion portion 25, and the same number of splices as the number of the plurality of splice connection portions 14 are accommodated in the upper part of the inner surfaces of the left and right side walls 24. The part 30 is projected in series with a gap on the same side wall, and is projected in parallel on the left and right side walls.

  As shown in FIG. 3, the splice accommodating portion 30 has a box shape with an upper surface opening. As shown in FIG. 3, a protruding side wall 31 that faces the side wall 24 of the protector body 21 with a space between the protruding side wall 31 and the side wall 24 of the protector body 21. A lower holding wall 32 that connects to the splice connecting portion 14, and a closing wall 33 on one end side that faces the distal end side of the splice connecting portion 14, and a wire terminal that is continuous with the splice connecting portion 14 at a position facing the closing wall 33. The drawer opening 34 is provided. The upper end 31 a of the projecting side wall 31 has the same height as the upper end 24 a of the side wall 24 of the protector body 21, and the upper surface opening 35 of the splice housing 30 is closed by the lid 22.

  From the upper end 24a of the side wall 24 of the protector body 21 and the upper end 31a of the protruding side wall 31, a pair of flexible wire pull-out prevention pressing pieces 36 project in the opposite direction. . The tip ends of the pair of pressing pieces 36 are separated from each other by a required dimension, and the separation dimension is set to be smaller than the minimum diameter of the splice connecting portion 14.

  As shown in FIG. 3, the lower holding wall 32 of the splice housing 30 is provided with a water draining opening 37 at a back position in contact with the closing wall 33.

  The splice housing 30 is a set of two splice housings 30A and 30B. As shown in FIG. 2, the set of splice housings 30A and 30B is spaced from the same side wall 24 of the protector body 21. In addition, they are adjacent to each other in series and are provided with respective wire drawing openings 34 facing each other. In addition, the splice housing walls 30A and 30B are provided as a pair projecting symmetrically on the left and right side walls.

In order to accommodate and fix the wire harness 10 in the protector 20 having the above-described configuration, first, the trunk line 11 is inserted into the trunk insertion part 25 of the protector main body 21, and then, as shown in FIG. The splice connection portions 14A and 14B at the tips of the branch lines 13A and 13B are distributed to the set of splice housing portions 30A and 30B and housed one by one, and the branch line 13A continuous to the splice connection portions 14A and 14B. , 13B is pulled out from the drawer opening 34.
As shown in FIG. 1 (C), four branch lines 13 may be grouped into a set, distributed in the front-rear direction and the left-right direction, and stored one by one in the left and right splice storage portions.
At this time, the splice connecting portion 14 is inserted while pushing down the pressing piece 36 from the upper surface opening 35 of each splice accommodating portion 30, as shown in FIG. After the insertion, as shown in FIG. 5 (B), the pressing piece 36 is elastically restored and the branch line 13 is pressed from above to restrict the removal.

  Similarly, the other splice connection portions 14 are also housed one by one in each splice housing portion 30, and as shown in FIG. 6, all the splice connection portions 14 (14A, 14B) are connected to the splice housing portions 30 (30A, 30B). ). Thereafter, as shown in FIG. 7, the lid 22 is placed on the upper surface of the protector body 21, and the locking claw 27 is inserted and locked into the locked frame portion 28 to be locked.

  In the splice housing structure, by inserting one splice connection portion 14 into each splice housing portion 30, each splice connection portion 14 can be easily positioned and accommodated, and the protector body 21 has a plurality of splices. Since the accommodating portions 30 are provided in a separated and independent state with a gap therebetween, each splice connecting portion 14 can be insulated by accommodating one splice connecting portion 14 in one splice accommodating portion 30. .

In addition, since the splice accommodating portion 30 is provided on the upper portion of the side wall 24 positioned above the bottom wall 23 of the protector main body 21, even when the protector main body 21 is submerged, the splice accommodating portion 30 is transmitted through the bottom wall 23. It is possible to prevent water from entering the inside, and it is possible to prevent a short circuit between the splice connecting portions 14 due to water immersion.
Furthermore, since the upper surface opening 35 of the splice housing 30 is closed by the lid 22, it is possible to prevent water from entering the splice housing 30 from the upper surface opening 35. Further, even if the inside of the splice housing 30 is submerged, water can be discharged from the drain opening 37, so that it is possible to prevent the splice connector 14 from being submerged for a long time.

  Since the splice connecting portion 14 is accommodated in the splice accommodating portion 30 in this way, the same effect as that obtained when the splice connecting portion 14 is waterproofed by preventing insulation treatment and water immersion can be obtained. In addition, since it is not necessary to individually insulate and waterproof the splice connection portion 14 and the conductor can be accommodated while being exposed, man-hours can be reduced and workability can be improved. In addition, since an insulating protective material such as a cap that has been conventionally required is not required, the number of parts can be reduced, and the cost can be reduced.

  Further, since the splice connection portion 14 is housed and fixed in each splice housing portion 30 after the trunk line 11 is inserted into the protector body 21, the branch line 13 having the splice connection portion 14 is previously separated from other electric wires. There is no need. In addition, since a plurality of the splice accommodating portions 30 are arranged in parallel on the left and right side walls 24 of the protector body 21 at intervals in the front-rear direction, the branch lines 13 are gathered at a limited arrangement position. Is also unnecessary.

  In addition, since the trunk line 11 inserted into the protector main body 21 can be dispersed and pressed at a plurality of locations by the plurality of splice accommodating portions 30 that are arranged in parallel in the left and right and front and rear directions as described above, the wire harness 10 Can be easily and reliably positioned and fixed, and also from this point, the workability of the wire harness assembly can be improved.

  Furthermore, since the disconnection of the splice connecting portion 14 is regulated by the pressing piece 36 and the lid 22, it can cope with the diameter difference of the splice connecting portion 14 due to the specification difference. Nevertheless, various splice connections 14 of different diameters can be accommodated.

  Further, since a plurality of the splice accommodating portions 30 are formed using the dead space at the upper corner of the protector main body 21 that does not obstruct the insertion of the trunk line 11, a large number of splice connecting portions 14 are accommodated in a limited space. While being able to do, the enlargement of the protector 20 and by extension, the enlargement of the diameter of the wire harness 10 can be suppressed.

In the present embodiment, a plurality of splice housing portions 30 are arranged in parallel at intervals on the outer surfaces of the side walls 24 of the protector body 21, and the splice connecting portions 14 are housed in the splice housing portions 30.

  The protector accommodating portion 30 is provided adjacent to the same side wall 24 as a pair of two protector accommodating portions 30A and 30B, and the wire drawing openings 34 are opposed to each other. The form is the same. The side wall 24 of the protector body 21 is provided with a wire lead-out recess 29 cut out from the upper end 24a at a position corresponding to the gap between each pair of protector housing portions 30A, 30B. 13A and 13B are inserted and pulled out of the side wall 24, and the splice connecting portions 14A and 14B at the tips of the branch lines 13A and 13B are distributed and accommodated in the protector accommodating portions 30A and 30B.

  The lid 22 that closes the upper surface opening of the protector body 21 is formed integrally with the upper end 31a of the protruding side wall 31 of the splice housing 30 formed on the outer surface side of one side wall 24 so as to be openable and closable via a thin hinge portion 26. is doing. The lid 22 has a rectangular shape in plan view, and its open / close end 22a extends to the position of the protruding side wall 31 of the splice housing 30 that projects from the outer surface of the other side wall 24 of the protector body 21. By closing 22, the upper surface opening of the protector body 21 and the upper surface opening of the splice housing 30 can be closed.

The lid 22 has a locking claw 27 protruding below the opening / closing end 22 a, and a locked frame portion 28 for inserting and locking the locking claw 27 protruded from the outer surface of the other side wall 24. It is formed on the outer surface of the protruding side wall 31 of the splice housing 30.
Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  In the present embodiment, since the splice accommodating portion 30 is formed outside the both side walls 24 of the protector main body 21, the main line insertion portion 25 in the protector main body 21 can be widely secured as shown in FIG. Can be suitably used for the splice housing structure of the thick wire harness 10.

  The present invention is not limited to the above embodiment. In particular, as shown in FIG. 10, the splice accommodating portion 30 may be provided in parallel on both the inner surface side and the outer surface side of the both side walls 24 of the protector body 21.
