Description

The present invention relates to a wiring holder for fixing wiring and cables of electrical equipment such as electric wires and wiring bundles to a chassis.

This type of wiring holder includes a holding portion and an attaching portion, and supports the wiring by the holding portion, and the attaching portion can be fixed to the chassis with one touch in many cases.
A clamp 1 (wire stand) described in Patent Document 1 is one of wiring holders and includes a holding portion and an attachment portion (fixing mechanism).
The holding part includes a base 2, an opening / closing member 3, a connecting member 9, and the like.
The mounting portion includes a support column 12, a pair of elastic locking pieces 13, an arrow-shaped snap 14, a relay piece 16 along the support column 12, an elastic piece 17 projecting on both sides of the support column 12, and side pieces on both sides. 18 and a secondary elastic piece 19 projecting outward from the left and right sides of the base 2.
And the said attachment part presses a pair of elastic locking pieces 13 from both sides with a finger | toe, shrinks an arrowhead-shaped snap, inserts it in the attachment port 21 of the board | plate material 20 as it is, and releases the board | plate material 20 ( It can be fixed to the chassis.

In the clamp 1 fixed to the plate member 20, the pair of snaps 14 are enlarged, and the locking portion of the movable end portion 15 is locked to the attachment port 21 from the back side. It will not come off. Further, the corners of the elastic pieces 17 projecting on both sides of the support come into contact with the surface of the plate member 20 and the upper ends of the side pieces 18 extending upward from the outer ends of the elastic pieces 17 are the upper ends of the connecting members 9 of the holding parts. By contacting the outer surface, the holding portion is urged upward by the elasticity provided by the elastic piece 17 and the side piece 18, and is in a stretched state based on the surface of the plate member 20.
For this reason, a gap is not generated between the movable end 15 of the snap and the back surface of the plate member 20, and so-called play is removed. Further, this stretched state is reinforced by the secondary elastic piece 19 disposed between the base portion 2 and the elastic piece 17.

Japanese Patent No. 4625398

The prior art clamp has a holding part and a mounting part, and can be fixed to the chassis with one touch. When the side piece 18 is pressed from both sides to remove the clamp, the upper end of the side piece 18 is held by the holding part. Resistance against contact with the outer surface of the connecting member 9, and the tip of the auxiliary elastic piece 19 is in contact with the upper surface of the elastic piece 17, so that it is curved and deformed upward. , The pressing operation becomes heavy. Further, there is a difficulty in that the sub elastic piece 19 must be accurately formed in a narrow space between the lower surface of the base portion 2 of the electric wire holding portion and the elastic piece 17.
The present invention solves such a problem, and is a wiring holder (in the above-mentioned clamp) in which the mounting state to the chassis is reliable, the operation for attachment / detachment is light, the structure is simple, and the molding is difficult. Equivalent)).

A holding portion having a base for supporting the wiring;
A mounting portion to be inserted into the mounting hole of the chassis;
Let it be a wiring holder which consists of an operation part which operates an attaching part.
The attachment portion is provided below the base portion, and the operation portion is provided between the base portion and the attachment portion.
The mounting portion includes a downward arrowhead portion having wings spread on both the left and right sides.
The operation part is composed of operation pieces which are symmetrically arranged on both the left and right sides of the attachment part with a distance from the attachment part.
Each operation piece has a connecting portion in the vertical direction and a spring portion provided at the upper end thereof.

The spring portion has a U-shaped lower horizontal portion composed of a lower horizontal portion, an upper horizontal portion, and a vertical portion connecting them, which is longer than the upper horizontal portion.
The operation piece has a lower horizontal portion attachment portion side end (inner end) in the spring portion coupled to the upper end of the coupling portion, and the lower end of the coupling portion is coupled to each of the left and right wing portions of the arrowhead portion.
When the mounting portion is engaged with the mounting hole of the chassis from the back side, the spring portion is compressed by contacting the upper lateral portion with the lower surface of the base and the lower lateral portion with the upper surface of the chassis. In addition, the structure is such that the left and right wings of the arrowhead-shaped part can be brought close to each other by pressing the operation part from the left and right.

  The lower horizontal part of the spring part is bent upward, and the vertical part is bent to the opposite side of the mounting part to determine the deformation direction of the operation piece when operating the operation part, making it easy to operate and at the time of compression May improve elasticity.

  By forming a portion of the lower surface of the base portion of the holding portion where the inner end (supporting leg side) of the upper horizontal portion of the spring portion comes into contact with the lower inclined surface that is inclined downward from the upper side to the inner side, the wiring holder There is a case where the resistance when the mounting portion is inserted through the mounting hole of the chassis is reduced, and the holding portion is biased upward when the operation portion is operated.

  The operation part may have a structure that is substantially contained within an outer dimension in the left-right direction including the locking part and the locking receiving part in the holding part when the wiring holder is attached to the chassis. Since there is no unnecessary protrusion in the attached wiring holder, it is preferable in avoiding the trouble of tangling the wiring.

Since the operation part is provided between the base part and the attachment part in the holding part, and the operation part is a left and right operation piece provided with a spring part coupled to each of the left and right wing parts of the arrowhead part of the attachment part. The left and right wings can be reduced by the operation piece, and the spring part of the operation piece is compressed between the holding part and the chassis, so that the spring part repels between the wiring holder and the chassis, and the wiring holder for the chassis. The mounting state can be a reliable mounting state without backlash.
Moreover, since the attachment of the wiring holder and the stable attachment state can be achieved with only the operation piece, an auxiliary elastic member or the like is unnecessary, and the structure of the attachment portion in the wiring holder can be simplified.
In addition, when the left and right operation pieces are pressed, the upper lateral inner end of the spring portion that contacts the lower surface of the base portion moves obliquely downward along the lower surface of the base portion, and due to the repulsion of the spring portion that is in a compressed state at the time of mounting. Since the mounting portion is biased in the direction of coming out upward from the mounting hole of the chassis, the operation of removing the wiring holder from the chassis can be performed easily and lightly.

1-3, the wiring holder [1] is composed of a holding part [2], a mounting part [3], and an operation part [4]. In this embodiment, flexible nylon, etc. The whole is integrally molded with synthetic resin.
The wiring holder [1] is often mounted upright with respect to the chassis 5 as shown in FIGS. 1 and 5, but is in an inverted state in which the chassis 5 is positioned upward or on the side where the chassis 5 is positioned on the side. There may also be a state such as a side mounting. In either case, the mounting structure for the chassis 5 does not change.
In the following description, the vertical, horizontal, and front-rear directions are defined based on the upright state of FIG. 1, but for convenience of explanation, these are relatively relative to the posture of the chassis 5 as described above. It will change.
1 and 5, reference numeral 6 denotes an attachment hole, into which the attachment portion [3] of the wiring holder [1] is inserted.

[Holding part]
In this embodiment, the holding portion [2] has a base portion 7 extending left and right (FIG. 1), and a left rising portion 8 and a right rising portion 9 are provided at both ends of the base portion 7 so as to open upward. The accommodating part 10 is formed. Reference numeral 11 denotes a wiring (wire, cable, etc.) supported by the accommodating portion 10.
In this embodiment, the right rising portion 9 extends upward from the left rising portion 8, and a constriction 12 is provided on the inner side surface at the same position as the upper end of the left rising portion 8. That is, the extension 13 is located above the constriction 12, and the extension 13 can be bent leftward about the constriction 12.

The upper end portion of the extension portion 13 is a locking portion 14 that is bent to the left, and a locking projection 15 is formed on the outer surface of the locking portion 14 at the center in the front-rear width direction. Note that the side of the locking projection 15 in the width direction of the locking portion 14 is a notch 16 (FIG. 4). A guide protrusion 18 of a lock receiving portion 17 described later enters the notch portion 16.
Reference numeral 19 denotes a wiring restraint, which is formed to protrude inside the extension portion 13.
At the upper part of the left rising portion 8 in the holding portion [2], a latch receiving portion 17 is formed.

The latch receiving portion 17 is formed along an outer wall provided with a long hole 20 that is long in the vertical direction, a pressing wall 21 provided on the inner side opposite to the outer wall, and one long side of the long hole 20 inside the outer wall. It is comprised with the guide protrusion 18 made | formed (FIGS. 2-4).
Moreover, the said base 7 of a holding | maintenance part [2] is fundamentally horizontal and it extends in the left-right direction, and the downward inclined surface which the lower surface of the both ends inclines downward from the upper side toward the inside (center side of the base 7) 22 (FIG. 1).

  From the above, as shown in FIGS. 1, 5 (b) and 5 (b), the holding part [2] supports the wiring 11 on the base part 7 and accommodates it in the accommodating part 10, and extends the extension part 13 of the right rising part 9. The housing portion 10 can be closed by bending horizontally from the constriction 12 and locking the locking portion 14 at the tip thereof to the locking receiving portion 17 of the left rising portion 8. When closing, as shown in FIG. 4, the notch portion 16 of the locking portion 14 is guided by the guide protrusion 18 of the locking receiving portion 17, so that the locking projection 15 is inserted from the long hole 20 of the locking receiving portion 17. It does not move from side to side and can be locked without failure. Further, the pressing wall 21 of the latch receiving portion 17 urges the latch projection 15 toward the long hole 20 as the latch projection 15 is pushed into the latch receiving portion 17. For this reason, once the latching protrusion 15 is engaged with the long hole 20, it does not come off easily, and the wiring does not fall off from the holding portion [2].

[Mounting part]
The attachment portion [3] includes a support leg 23 extending downward from the center of the lower surface side of the base portion 7 in the holding portion [2] and an arrowhead portion 24 formed at the lower end portion thereof and directed downward. The arrowhead portion 24 has flexible wing portions 25 on the left and right sides. The left and right wing portions 25 are pressed toward the support leg 23 to reduce the upper portion of the wing portion 25, or the pressure is released to release the wing portion 25. The top of the can be enlarged. When the interval between the wings 25 is reduced, the mounting hole 6 of the chassis 5 can be penetrated downward. When the interval between the wings 25 is increased below the chassis 5, the upper end of the wings 25 is Engage with the lower surface of the chassis 5 around the mounting hole 6.

(Operation section)
The operation part [4] is composed of operation pieces 26 and 26 which are symmetrically arranged on both the left and right sides of the attachment part [3]. Each operation piece 26 includes a vertical connecting portion 27 and a U-shaped spring portion 28 provided at the upper end thereof. As shown in FIGS. 2 and 3, these are formed in a wide shape, and when deformed, the elasticity due to the flexibility of returning to the original is exhibited.
The spring portion 28 includes a lower horizontal portion 29, an upper horizontal portion 30, and a vertical portion 31 connecting them. The lower horizontal portion 29 is longer than the upper horizontal portion 30, but as a whole, has a U-shape that is open to the inside (support leg 23 side). In this embodiment, the lower horizontal portion 29 is slightly curved upward, and the vertical portion is slightly curved outward.
The outer dimension in the left-right direction of the operation part [4] is the same as or slightly smaller than the outer dimension in the left-right direction including the locking part and the locking receiving part of the holding part [2] when the wiring holder is attached to the chassis. It has a structure that does not protrude to the side of the holding portion [2].

The left and right operation pieces 26 are coupled to the left and right wing parts 25 of the arrowhead part 24 at the lower end of the connecting part 27, and symmetrically between the base part 7 and the attachment part [3] in the holding part [2]. When the mounting portion 3 is engaged with the mounting hole 6 of the chassis 5, the inner end (the support leg 23 side) of the upper lateral portion 30 of the spring portion 28 is the base portion 7 in the holding portion [2]. Of the lower surface of the lower surface of the lower surface of the lower surface of the lower surface of the lower surface of the lower surface of the lower surface of the lower surface.
When the vertical portion 31 of the left and right operation pieces 26 is pressed while being pinched from both sides, the distance between the left and right wing portions 25, 25 can be reduced via the connecting portion 27 (FIG. 5 (B)). On the other hand, when the pressing is stopped, the distance between the left and right wing portions 25 is increased.

When the wiring holder [1] of the embodiment is used, the wiring 11 may be supported after the wiring holder [1] is attached to the chassis 5, or the wiring holder [1] is attached to the wiring 11. You may attach to the chassis 5 after attaching.
In any case, when attaching the wiring holder [1] to the chassis 5, as shown in FIG. 5 (a), the attachment portion [3] may be pushed into the attachment hole 6 from above. The arrow-shaped portion 24 of the attachment portion [3] has a space between the left and right wing portions 25 reduced by a lateral force received from the periphery of the attachment hole 6 by pressing from above, and penetrates the attachment hole 6 downward (FIG. 6) from displacement position (a) to (b)). Since the penetrating arrowhead portion 24 loses pressure from the side, the space between the wing portions 25, 25 is enlarged and engaged with the lower surface of the chassis 5 (displacement position (c) in FIG. 6).

  In a state where the left and right wing portions 25, 25 of the arrowhead portion 24 are engaged with the lower surface of the chassis 5, the operation pieces 26, 26 of the operation portion [4] are in the holding portion [2] as shown in FIG. The spring portion 28 is compressed between the lower surface of the base portion 7 and the chassis 5 (displacement position (c) in FIG. 6). Therefore, as shown by the upward arrow in FIG. 5B due to the elasticity of the spring portion 28, the holding portion [2] is pushed upward with respect to the chassis 5, and the mounting portion [3] The play between the left and right wing portions 25 and the lower surface of the chassis 5 is eliminated. As a result, even if vibration is applied to the chassis 5 or the wiring 11, the mounting state is ensured and stabilized without rattling or falling off. At this time, as shown in the figure, the lower horizontal portion 29 of the spring portion is slightly bent upward, the vertical portion 31 is slightly bent to the side opposite to the attachment portion [3], and the operation portion [4] is If the deformation direction of the operation piece 26 is determined when operating, it becomes easier to operate and the elasticity at the time of compression is improved.

Further, when the spring portion 28 is compressed as described above, the tip of the upper lateral portion 30 moves outward (the side away from the support leg 23) along the descending inclined surface 22 of the base portion 7 in the holding portion [2]. It is possible to perform the operation lightly without sliding and causing resistance when the wiring holder [1] is pushed into the mounting hole 6. In particular, when the thickness of the chassis 5 is large and the spring portion 28 is strongly compressed and the attachment portion [3] needs to be passed through the attachment hole 6, the insertion load can be reduced.
The outer dimension in the left-right direction of the operation part [4] is the outer dimension in the left-right direction including the locking part and the locking receiving part of the holding part [2] when the wiring holder [1] is attached to the chassis. It is the same as or slightly smaller than that of the holding part [2] and does not protrude to the side. In this way, since there is no unnecessary protrusion in the attached wiring holder, the trouble of tangling the wiring is avoided.

When the wiring holder [1] is removed from the chassis 5, as shown in FIG. 5C, the vertical portions 31, 31 of the operation pieces 26, 26 in the operation unit [4] are pinched from both sides and pressed (see FIG. 5). 6 displacement position (b)). Then, the distance between the left and right wing portions 26, 26 of the attachment portion [3] is reduced via the connecting portion 27, and the engagement between the arrowhead portion 24 and the lower surface of the chassis 5 is released. When the engagement is released, the inner end of the upper horizontal portion 30 of the spring portion 28 that is in contact with the lower surface of the base portion 7 moves obliquely downward along the lower surface of the base portion 7, and the operation portion [ 4], the holding portion [2] is moved upward by the urging of the spring portion 28, the arrowhead portion 24 moves upward through the mounting hole 26, and the wiring holder [1] is detached from the chassis 5.
As described above, the operation of removing the wiring holder [1] from the chassis 5 is performed by releasing the engagement of the mounting portion [3] just by pinching the left and right operation pieces 26 and 26 and simultaneously holding the holding portion [2] upward. Easy to operate because it moves to Further, when pressing the left and right operation pieces 26, 26, the inner end of the upper horizontal portion 30 slides inward (side closer to the support leg 23) along the descending inclined surface 22 of the base portion 7 in the holding portion [2]. Since it moves and moves holding part [2] upwards, operation can be performed lightly.

Note that the operation of pinching the left and right operation pieces 26, 26 as shown in FIG. 5C from the left and right may also be performed when attaching the wiring holder [1] to the chassis 5. If it does in this way, the attachment part [3] of the wiring holder 1 can be lightly inserted into the attachment hole 6.
Thus, one embodiment has been described. In the present invention, the form of the holding portion [2] is required to have the base portion 7, but is not particularly limited otherwise. For example, instead of a form in which the opening of the housing part 10 is closed by the extension part 13, a form in which locking pieces for retaining are projected inward from the upper ends of the left rising part 8 and the right rising part 9, or a left rising part A configuration in which one of the right rising portion 9 and the right rising portion 9 is configured integrally with a binding band is conceivable.
