Description

  The present invention relates to a clamp used when a long member such as a wiring or a wire harness is fixed to a housing or the like.

  In some cases, a plurality of wirings and wire harnesses are arranged so as to pass through the same position, and in order to prevent them from becoming messy, they may be bound and fixed to a housing or a column. Conventionally, in order to fix a wiring to a housing or the like, a band portion for wrapping around the wiring to fix the wiring and a locking portion and a band portion for fixing the main body portion to the housing are inserted and locked. There has been proposed a band clamp having a main body portion on which a band stopper portion is formed (see Patent Document 1).

JP 2004-48901 A

  The band clamp described in Patent Document 1 is formed by a flexible resin because it deforms and locks the band part and the band stopper part. For this reason, it is relatively easy to insert a tool or the like into the locking portion between the band portion and the band stopper portion to release the locking, pull out the band portion, open the band portion, and remove the wiring or the like. Therefore, it has been difficult to use the band clamp as a sealing tool used in a scene where the opening of the band portion should be prohibited.

  The objective of this invention is providing the clamp which can suppress opening.

The first aspect of the present disclosure, which has been made to solve the above-described problem, includes a main body portion in which an insertion hole is formed and a locking piece is provided inside the insertion hole, and is connected to the main body portion. And an extending portion extending from the band, the recess having an opening in a direction intersecting with the extending direction, and an extending portion that can be inserted into the insertion hole. The clamp is characterized in that, in a state where the extension portion is inserted into the insertion hole, the locking piece is accommodated in the recess and is covered with the extension portion and locks the extension portion. It is.

  In the clamp configured in this way, the extension part and the locking piece of the main body part are locked, so that the band and the main body part cooperate to form a grip ring part. The long member is held. Since the extending portion covers the locking piece accommodated in the recess, it becomes difficult to operate the locking piece from the outside. Therefore, it is possible to suppress the release of the engagement between the engagement piece and the extending portion, and it is possible to suppress the opening of the band.

  The portion covered by the extension is, for example, a side surface of the locking piece, that is, a side surface in a direction that intersects the depth direction of the insertion hole and along the surface of the insertion hole in which the locking piece is provided. The opening side into which the extension part of the insertion hole in the locking piece should be inserted corresponds. In this case, it can suppress that a latching piece is operated from the opening side which inserted the extension part of the insertion hole.

  Also, if the insertion hole is a hole that penetrates to the back side of the main body and there is a risk that the locking piece may be operated from the opening on the back side, the back side (back side) of the insertion hole in the locking piece is also You may comprise so that it may be covered with an extension part.

The recess is not limited to the one that completely covers the periphery of the locking piece, and may be provided with a gap as long as it can suppress the operation of the locking piece by entering a tool or the like from the outside.
According to a second aspect of the present disclosure, in the clamp of the first aspect described above , the locking piece has a tongue-like shape extending along a direction in which the extension portion is inserted.

  In the clamp configured as described above, when a load in the direction of pulling out from the insertion hole is applied to the extension portion in a state where the concave portion is locked to the locking piece, the tongue-shaped locking piece is torn or refracted. To do. In that case, it is difficult to properly lock the extension part with the locking piece even if the extension part is inserted into the insertion hole again. Checks can be made easily.

In addition, the direction where the extension part mentioned above is inserted is the depth direction of an insertion hole, Comprising: It is a direction toward the back of a hole.
According to a third aspect of the present disclosure, in the clamp according to the first aspect or the second aspect described above, in the state where the main body portion is inserted into the insertion hole, the extension portion is the When the band is displaced in the intersecting direction intersecting the surface through which the band is displaced when inserted into the insertion hole, the band is brought into contact with the band in a direction more than preset by contacting with the band. It has the displacement suppression part which suppresses displacement, It is characterized by the above-mentioned.

  The clamp comprised in this way can suppress the displacement of the band to the said crossing direction by a displacement suppression part. Therefore, it can suppress that the latching | locking to the latching piece of an extension part is cancelled | released by bending or twisting a band in the said crossing direction.

Embodiments of the present invention will be described below with reference to the drawings.
[Example]
(1) Overall configuration The clamp 1 of this embodiment is used when a long member such as a wiring is fixed to an attachment object, and the overall view is shown in FIGS. . In order to briefly describe the relative positional relationship between the parts constituting the clamp 1, the following directions are defined in the front / rear, left / right, and up / down directions. It is only a definition for showing, and does not prescribe an attachment direction when using the clamp 1 of the present embodiment.

  The clamp 1 includes a main body portion 11, two bands 13, and two extending portions 15. The main body 11 has a substantially rectangular shape when viewed from above, extending in the front-rear direction and the left-right direction. The two bands 13 are connected to each other at the right end of the main body 11 and extend in the right direction along the front-rear direction, and an extension 15 provided at the extended end extends upward. The direction in which the band 13 and the extending portion 15 extend naturally changes if the band 13 is displaced.

  On the upper surface of the main body portion 11, a groove portion 21 having a length in the front-rear direction, three partition walls 23 arranged at intervals on the right side of the groove portion 21 in the front-rear direction, and the partition walls 23 across the groove portion 21. There are formed three partition projections 25 arranged in a positional relationship, and two insertion holes 27 which are arranged on the left side of the groove portion 21 with a space in the front-rear direction and having a depth in the vertical direction.

  The interval between the partition walls 23 and the interval between the partition projections 25 are both formed to be slightly wider than the width of the band 13 in the front-rear direction. In addition, the partition wall 23 and the partition protrusion 25 are examples of the displacement suppression part in this invention.

  The insertion hole 27 is a substantially rectangular hole as viewed from above. A locking piece 31 is provided inside the insertion hole 27. As shown in FIG. 2C, the locking piece 31 extends from the left inner surface of the insertion hole 27 in the axial direction (right direction) of the insertion hole 27, and its tip extends downward. Tongue shape. The locking piece 31 has a plate shape extending from the inner surface and can be said to have a shape in which the width direction is not connected to the surroundings. The locking piece 31 is formed with a thin portion 31a that is thinner than the periphery thereof in a region located on the proximal end side that is connected to the insertion hole 27 from the distal end from which the locking piece 31 extends.

The insertion hole 27 may be a hole that penetrates the main body 11 as in this embodiment, or may be a hole that does not penetrate.
A positioning protrusion 33 and two snaps 35 extending downward from the front and rear end portions of the main body 11 are provided on the back surface of the main body 11. With the positioning protrusions 33 and the snaps 35, the main body 11 is attached to the attachment object 3 as shown in FIGS. 2 (a) and 2 (b). Note that holes 3 a and 3 b corresponding to the positioning protrusions 33 and the snaps 35 are provided in the attachment object 3 in advance.

The band 13 is a long plate-like member having a length in the left-right direction. The connecting portion 13 a of the band 13 with the main body 11 is formed thinner than the main portion of the band 13.
The extending portion 15 extends in a direction intersecting with the extending direction (the upward direction in FIGS. 1A to 1J) at the point where the band 13 extends.

  As shown in FIG. 3, the extending portion 15 has a columnar shape having an inclined surface at the tip, and a recess 41 having an opening on a surface (a right side surface in the present embodiment) in a direction intersecting the extending direction. Is formed. The recess 41 is formed by being surrounded by a pair of side walls 43, a bottom wall 45, and a top wall 47. The upper side of the top wall 47 is an inclined surface that is inclined toward the opening side of the recess 41. The bottom wall 45 is wider in the front-rear direction than the band 13, and extends rightward from the extending portion 15.

  The extending portion 15 is formed slightly smaller than the insertion hole 27 and can be inserted into the insertion hole 27 by displacing the band 13. When inserting, the extension part 15 is inserted downward so that the top wall 47 faces downward.

  When the extending portion 15 is inserted into the insertion hole 27, the locking piece 31 is first pressed by the inclined surface of the top wall 47 and displaced to the left. When the top wall 47 is inserted deeper than the locking piece 31, the locking piece 31 returns to its original position by the elastic force, and the inner surface on the top wall 47 side is engaged as shown in FIG. The extension part 15 is locked in contact with the tip of the stop piece 31.

  In the state described above, the main body part 11 and the band 13 cooperate to form a grip ring part around the groove part 21. The main body 11 is fixed to the attachment object 3 using the snap 35, and the long member 5 is fixed to the attachment object 3 by fixing the long member 5 to the grip ring.

  At this time, as shown in FIG. 4B, the locking piece 31 is accommodated in the recess 41 and the periphery thereof is covered with the extending portion 15. Specifically, the front and rear sides of the locking piece 31 are covered with a pair of side walls 43, the upper side is covered with the bottom wall 45, and the lower side is covered with the top wall 47.

  Further, when the extension portion 15 is inserted into the insertion hole 27, the band 13 is bent at the thin connecting portion 13 a as shown in FIGS. 2A and 2C, and the band 13 extends along the main body portion 11. Position. At this time, as shown in FIG. 4A, the partition wall 23 and the partition projection 25 are positioned at positions along the front and rear side surfaces of the band 13.

(2) Effect In the clamp 1 of this embodiment, when the extended portion 15 is inserted into the insertion hole 27 and locked, the extended portion 15 covers the locking piece 31, so that it is engaged using a tool or the like from the outside. It becomes difficult to operate the stop piece 31. Therefore, it can suppress that the latching of the locking piece 31 and the extension part 15 is cancelled | released, and it can suppress that the band 13 is open | released.

  In addition, since the extending portion 15 is formed in a columnar shape, it is easy to fill the gap of the insertion hole 27, and the opening of the insertion hole 27 is widely covered by the bottom wall 45. It is possible to further suppress the release of the locking with the extending portion 15.

Further, in the clamp 1 of this embodiment, the locking piece 31 has a tongue-like shape, so that the locking piece 31 is damaged when the extension portion 15 is forcibly pulled out. Then, even if the extension portion 15 is inserted into the insertion hole 27 again, it becomes difficult to properly lock the extension portion 15 to the locking piece 31, so that the extension portion 15 is pulled out and the grip ring is opened. It is possible to easily check whether or not.
In addition, since a part of the locking piece 31 is the thin part 31a, the locking piece 31 is easily damaged at the portion, and it can be easily found that the extension part 15 has been pulled out.

  Further, the surface through which the band 13 is displaced when the extension portion 15 is inserted into the insertion hole 27 by the partition wall 23 and the partition projection 25 in a state where the extension portion 15 is inserted into the insertion hole 27. When the band 13 is displaced in the intersecting direction (front-rear direction) intersecting with the (surface extending in the left-right direction and the up-down direction), the partition wall 23 and the partition projection 25 come into contact with the band 13. Therefore, it is possible to prevent the band 13 from being displaced in the intersecting direction more than preset, and the band 13 is bent or twisted in the intersecting direction so that the locking of the extending portion 15 to the locking piece 31 is released. Can be suppressed.
