The present invention relates to a holding structure.

[0002]

2. Description of the Related Art FIG. 6 shows a structure for fixing a plurality of electric wires inside an electric device as one form of a conventional electric wire holding structure.

In FIG. 6, reference numeral 31 indicates a wall portion of the main body of the apparatus, and a part of the wall portion 31 is cut and raised in an inclined shape to form a pair of wire holding pieces 32. Each holding piece 32 has a claw portion 33 facing inward at the tip, and the claw portion 33 can hold a plurality of electric wires 34 without coming out.

The electric wire 34 is inserted into the inner accommodation space 35 with one of the holding pieces 32 bent inward.
Similarly, when taking out the electric wire 34, either one of the holding pieces 3
2 is bent inward.

However, in the above structure, since the electric wire housing space 35 between the pair of inclined holding pieces 32 and the wall portion 31 is narrow, the number and thickness of the electric wires that can be inserted are limited, For example, there is a problem that it cannot be applied to a case where a large number of electric wires or thick electric wires are inserted and fixed in an automobile or the like.

Therefore, for a wire harness for an automobile, for example, a harness holding structure as shown in FIGS. 7 and 8 is adopted.

In the structure shown in FIG. 7, as shown in FIG. 7 (a), one wall is inclined to the wall 42 on the base side, for example, the wall of the electric junction box, the wall of the harness protector or the wall of the harness clip. -Shaped harness holding piece 43 and a large curved harness holding arm 44 are provided in a protruding manner, and the other inclined harness holding piece 45 is integrally formed at the tip of the arm, and between the harness holding pieces 43, 45. A gap 46 for inserting a harness is configured, and the wire harness 41 (FIG. 7B) is inserted from the gap 46 into the harness holding arm 44 so that the wire harness 41 can be held in the harness holding arm 44. .

The wire harness 41 comprises a plurality of insulation-coated electric wires bundled with a vinyl tape winding or a protective tube made of synthetic resin. It is also possible to use a single cabtire cable in place of the wire harness 41.

Further, the structure shown in FIG. 8 includes a pair of left and right wall portions 72 standing up from the base wall 71, and a pair of holding pieces 73 folded back inwardly in a slanting manner at the tip end side of the wall portion 72. The harness holding member 70 is configured with the above. A wide space 74 for inserting a harness is formed between the pair of wall portions 72. A relatively wide harness insertion gap 75 is formed between the pair of holding pieces 73.

The wire harness 76 includes a pair of holding pieces 73.
Is bent inward and inserted into the harness insertion (accommodation) space 74. The outer diameter of the wire harness 76 is set larger than that of the harness insertion gap 74.

In FIG. 8, a pair of holding pieces 73 are provided with an insertion space 74.
The pair of holding pieces 73 may be located below or beside the insertion space 74 in actual use. Further, it is possible to insert and hold a window washer hose, a driving cable or the like instead of the wire harness 76.

[0012]

However, in the structure shown in FIG. 7, as shown in FIG. 7 (b), the wire harness 41 is pulled out as shown by an arrow A due to, for example, vibration while the automobile is running. When a force in the (disengagement) direction is applied, the wire harness 41 causes both harness holding pieces 43, 45 to
There is a concern that both harness holding pieces 43, 45 will open wide as shown by arrow B by contacting the tip of the wire harness 41, and the wire harness 41 will slip out of the gap 46.

Further, in the structure shown in FIG. 8, the wire harness 76 has one of the holding pieces 73, especially when the pair of holding pieces 73 are arranged below or on the side of the insertion space 74. There was a concern that the holding piece 73 would lose its force and bend outward when the wire was strongly pressed, and the insertion gap 75 would expand, causing the wire harness 76 to pop out of the insertion gap 75.

Further, a pair of holding pieces 7 are provided to enhance the holding force.
When the rigidity of 3 is increased, the wire harness 76
Requires a large force when inserting into the holding member 70,
There was a problem that the workability of inserting the wire harness 76 deteriorates. Further, since it is not possible to hold a wire harness having a diameter smaller than that of the insertion gap 75, there is a problem that the outer diameter of the wire harness 76 is limited and a plurality of wire harnesses having a small diameter or electric wires cannot be used. These problems apply not only to the wire harness 76 but also to the window washer hose, the driving cable, and the like.

In view of the above points, the present invention can reliably hold a long article such as a wire harness, an electric wire, a hose, or a cable against a force in the direction of withdrawal, regardless of its thickness. An object of the present invention is to provide a holding structure for a long product that allows the long product to be easily inserted.

[0016]

In order to achieve the above object, a holding structure for a long article according to claim 1 of the present invention has a pair of holding pieces inclined with respect to a space for inserting the long article. In the holding structure for a long article, the holding piece on one side is short and the holding piece on the other side is formed long, and the tip end portion of the other long holding piece is formed in the extension direction of the tip end of the one short holding piece. Alternatively, it is characterized in that they are located so as to face each other so that the intermediate portions in the longitudinal direction intersect. With the above configuration, a gap for inserting a long article is formed between the tip portions of both holding pieces, and a long article having a diameter larger than the gap pushes both holding pieces to bend inward, and from the widened gap. Inserted in the inner space. Simultaneously with the insertion of the long article, both holding pieces are elastically restored so that both the tip portions or the tip portions and the longitudinal intermediate portion face each other. When a force is applied to the long article in the direction of withdrawal, the tip or the longitudinal middle portion of the long holding piece is pushed by the long article, and the long holding piece bends outward while the tip or the longitudinal middle portion thereof is bent. The part is brought into contact with the tip of the short holding piece. As a result, the gap is completely closed and the long article is prevented from coming out. Even if more force is applied in the direction of withdrawal, both holding pieces will bend outward, and the tip of the short holding piece will slide along the longitudinal direction of the long holding piece, and the gap will always be closed. The escape of the article is prevented. This action is exhibited regardless of the diameter (thickness) of the long article. If the length of the long holding piece is such that the tip of the long holding piece abuts the tip of the short holding piece, the tip of the long holding piece is located opposite to or in contact with the tip of the short holding piece, and if it is longer than this, the inner holding Since it does not protrude into the space, it does not interfere with the long articles, the inside storage space can be widely used, the long articles can be smoothly and easily inserted into the storage space, and unnecessary interference with the long articles occurs.

It is characterized in that they are located so as to face each other so that the tip end portion or the longitudinal middle portion of the piece intersects. With the above configuration, the long article is inserted into the holding arm through the gap between the two holding pieces by pushing the pair of holding pieces open, and when a force in the extracting direction acts on the long article, the long article Pushes against the other long holding piece to displace the other holding piece in the direction in which the long article comes out, and the tip of the other holding piece or the longitudinal intermediate portion is touched so that it crosses the tip of the one short holding piece. Contact. As a result, the gap between both holding pieces is completely closed, and the long article is enclosed in the space surrounded by at least both holding pieces and the holding arm. This reliably prevents the long article from slipping out. In particular, since one short holding piece is less likely to bend (displace less) than the other long holding piece, the other long holding piece holds one short holding piece in a state in which a force in the withdrawal direction acts on the long article. The state of being in contact with the piece is ensured.

According to a third aspect of the present invention, there is provided a long article holding structure according to the second aspect, wherein the holding piece other than any one of the holding pieces and the holding arm are on a base side wall portion.

It is about double. As a result, the long holding piece 26 is moved to the rear half 5
It has a characteristic that it bends and rotates at 6 and does not bend at the front half 55.

Due to this characteristic, when the wire harness 59 is inserted into the holding member 22 in the direction of arrow C in FIG. 4, the long holding piece 26 bends inward so as to be bent from the base side, and the wire harness 59 is inserted. It can be performed easily and smoothly with a small force. In addition, the arrow direction D in FIG.
When the wire harness 59 is moved to and the long holding piece 26 is pushed in the harness extracting direction (outward), the rigid first half portion 55 of the long holding piece 26 maintains the straight state and the short holding piece 25 is held. Since the long holding piece 26 does not bend over the entire length, the wire harness 59 can be reliably received with respect to the force in the direction B, so that the wire harness 59 can be pulled out. Is reliably prevented.

The thick portion 55 of the long holding piece 26 is not limited to the front half portion and may continue to the vicinity of the base end portion without any problem in actual use. However, the plate thickness of the portion of the long holding piece 26 on the base end side (root side), that is, the portion that starts to incline downward obliquely from the rising wall portion 24 through the curved portion 57 is as thin as the short holding piece 25. It is necessary to ensure the bending of the long holding piece 26 when the harness is inserted.

The thick front half portion 55 of the long holding piece 26 continues to the thin rear half portion 56 on the inner surface side (harness insertion space side) through the step portion 58. The outer side surface 60 of the long holding piece 26 is a straight flat surface. Thereby, the tip of the short holding piece 25 can be smoothly slidably contacted with the outer surface 60 of the long holding piece 26. When the wire harness 59 pushes the holding piece 26, which is longer than the state shown in FIG. 5, outwardly, the short holding piece 25 becomes longer.
The outer surface 6 of the long holding piece 26 is pushed by 6 and bends outward.
It slides smoothly along 0 and absorbs the pressing force.

In addition to the above structure, a large-diameter protruding portion (indicated by reference numeral 52) having a spherical section (horizontal column shape) in vertical cross section is integrally formed at the tip portion 52 of the long holding piece 26, and The outer diameter is formed to be larger than the wall thickness of the front half portion 55 of the long holding piece 26. This large-diameter protrusion 52 has a long holding piece 2
6 or the part thereof. Protrusion 52
And the center of the holding piece front half portion 55 coincide with each other, and the curved outer peripheral surface 52 of the protrusion 52 is provided on both front and back sides of the holding piece front half portion 55.
a is protruding. The curved surface 52a is formed in the entire outer circumference of the projecting portion 52 except the intersection with the holding piece 26.

As shown in FIG. 5, when a force is applied to the wire harness 59 in the extracting direction B, the protruding portion 52 at the tip of the holding piece contacts the outer peripheral surface of the wire harness 59 with its curved surface 52a, so that the wire harness 59 is damaged. Sticking and wear are prevented. Further, the protrusion 52 abuts the tip of the short holding piece 25 at the curved surface 52a, so that the tip of the short holding piece 25 is prevented from being crushed and deformed. Tip 51 of short holding piece 25
Has a small-diameter protrusion (indicated by reference numeral 51) integrally formed therewith, whereby crush deformation and the like of the tip of the short holding piece 25 can be more reliably prevented. The small-diameter protruding portion 51 prevents the wire harness from being scratched or worn when it comes into contact with the wire harness (a wire harness having a diameter smaller than that shown in the drawing), and also allows the long holding piece 26 to slide more smoothly on the outer surface 60. The force in the wire harness extraction direction is absorbed more smoothly.

The projecting portion 51 having a small diameter projects downward (inside the harness insertion space 54) and does not project upward, but continues tangentially to the outer surface 61 of the short holding piece 25. Small diameter protrusion 51
Also has a curved surface (curved outer peripheral surface) 51a on the outer periphery. The outer diameter of the small-diameter protruding portion 51 is set to be slightly larger than the plate thickness of the short holding piece 25.

By setting the position of the contact point (horizontal tangent line) between the small-diameter protruding portion 51 and the large-diameter protruding portion 52 rearward of the center of the large-diameter protruding portion 52, that is, near the base, It is possible to reliably prevent the short holding piece 25 from sliding down from the protruding portion 52.

The directional characteristics such as "up and down" and "left and right" in the above embodiment differ depending on the usage of the holding member 22, and the up and down may be reversed or the up and down may be left and right. . In addition, the pair of wall portions 23, 24
It is also possible to form the pair of holding pieces 25, 26 so as to project obliquely inward from the middle portion in the height direction instead of the tip end. Further, similarly to the first and second embodiments, the tips of the short holding pieces 25 are made to face each other so as to intersect the longitudinal middle portion of the long holding pieces 26, that is, the holding pieces long in the tip extension direction of the short holding pieces 25. It is also possible to position the longitudinal intermediate portions of 26 so as to face each other.

Further, the third embodiment (FIGS. 3 to 5)
(I.e., a structure in which a thick portion (thick plate portion) 55 and a thin portion (thin plate portion) 56 are formed on the long holding piece 26, and a protruding portion 51 having curved surfaces 51a and 52a at the tips of the holding pieces 25 and 26). , 52 to form a short holding piece 25
The second and third embodiments (FIGS. 1 and 2) are configured such that the tips of the two are opposed to each other toward the tip of the long holding piece 26 so as to cross each other.
It is also effective to apply to the structure of.

Further, in each embodiment, the pair of holding pieces 3, 5, 13, 15, 25, 26 are lightly contacted in the free state (the state where no force is applied) without the gaps 6, 16, 53. May be. However, in this case, the insertability of the long articles 1, 11, and 59 is slightly deteriorated.

As a result, there is no concern that the long product will interfere with the outside and be damaged. Also,
In the case where the tip of the long holding piece has a length facing or in contact with the tip of the short holding piece, the tip of the long holding piece does not project into the inside accommodation space for a long time, so that the long article is not disturbed.
The inner storage space can be widely used, a long article can be easily inserted into the large storage space, or the storage space can be narrowed to achieve a compact structure.

According to the second aspect of the present invention, a long wire harness, that is, a large number of electric wires, which is a long article, is inserted into the holding arm from the gap between the holding pieces by pushing and opening the pair of holding pieces. Can be easily inserted at once. Then, when a force in the extracting direction acts on the long article in the holding arm, the long article presses the other long holding piece to displace the other holding piece in the withdrawing direction of the long article, and the other The tip of the holding piece or the longitudinal middle portion intersects and abuts the tip of one of the holding pieces having a short length, whereby the gap between the holding pieces is completely closed, and the long article is held at least with the holding pieces. It is confined in the space surrounded by the arm, and this reliably prevents the long article from slipping out. This action and effect are extremely effective especially against vibrations and the like while the vehicle is running. Further, with a simple configuration of a pair of holding pieces and one holding arm, it is possible to reliably prevent the long article from coming out, so that the parts cost and the manufacturing cost can be reduced.

According to the third aspect of the present invention, for example, the other long holding piece can be smoothly bent in the direction of rotation about the wall portion on the base side as a fulcrum. The closing operation of the gap between the holding pieces is smoothly performed.

According to the fourth aspect of the present invention, a force in the withdrawal direction acts on the long article in the holding arm, and the other long holding piece on the wall side is pressed outward by the long article. At this time, the other long holding piece is easily rotationally displaced and abuts on one short holding piece on the arm side, and one short holding piece is hard to be rotationally displaced. The holding piece is firmly supported, which reliably prevents the long article from coming out.

According to the fifth aspect of the invention, when a force is applied to the long article in the direction of withdrawal, the long holding piece is pushed by the long article and abuts on the short holding piece, so that the distance between both holding pieces is increased. Since it is closed, the long article can be reliably prevented from coming out regardless of the thickness. As a result, there is no concern that the long product will interfere with the outside and be damaged. Further, in the case where the tip of the long holding piece has a length facing or in contact with the tip of the short holding piece, the long holding piece does not project into the inner accommodation space for a long time, so that it does not interfere with the long article, The storage space can be widely used, and long articles can be easily inserted into the large storage space, or the storage space can be narrowed to achieve a compact structure.

According to the sixth aspect of the present invention, when the long article is inserted, the long holding piece bends so as to rotate about at least the flexible portion on the base side as a fulcrum. The insertion can be done easily. In addition, when a force is applied to the long article in the direction of withdrawal, at least the portion of the long holding piece except the root side has rigidity, and it does not bend and firmly receives the long article. The slip-out of the lengthy article is reliably prevented. Since both holding pieces are in contact with each other to close the gap, the above effect is exhibited regardless of the thickness of the long article.

According to the invention described in claim 7, when the long article is inserted, the root-side half of the long holding piece is curved with a relatively large diameter, and the stress is dispersed in a relatively long range. The long holding piece is not dented or damaged even by repeated insertion and removal, and the holding property of a long article is improved.

According to the invention of claim 8, the long article smoothly slides on the curved outer peripheral surface of the projecting portion of the tip of the long holding piece without being caught, so that the long article can be inserted into the inner accommodation space. Insertability is improved. Further, when a force is applied to the long article in the direction of withdrawal, the long article smoothly abuts the curved outer peripheral surface of the protruding portion, and there is no fear of abrasion or damage to the long article. Thereby, for example, the quality of the wire harness as a long article is guaranteed over time. Further, when the pair of holding pieces come into contact with each other, the tip of the short holding piece comes into contact with the protruding portion of the long holding piece and is stopped, so that the short holding piece is prevented from falling off from the long holding piece. The function of the holding piece of is always demonstrated reliably.

According to the ninth aspect of the invention, the long article smoothly slides on the curved outer peripheral surface of the projecting portion at the tip of the short holding piece, whereby the insertability of the long article is enhanced. Further, when a force is applied to the long article in the direction of withdrawal, the protruding portion of the short holding piece slides smoothly along the outer surface of the long holding piece, and the bending of both holding pieces is smoothly performed without being caught or worn. As a result, the withdrawal force of the long article is reliably absorbed, and the withdrawal is reliably prevented. Also, by stopping the protruding part of the long holding piece by the protruding part of the short holding piece to stop, the short holding piece is more reliably prevented from falling out of the long holding piece, and the function of the pair of holding pieces is always ensured. To be demonstrated.
