Description

  The present invention relates to a clamp.

  Conventionally, as a clamp for fixing the wire harness to the panel, a tape winding clamp that is attached to the wire harness by winding the tape on a predetermined position of the wire harness or a wire harness by tightening with a predetermined jig. A band clamp or the like that is attached and cuts and removes an excess portion after attachment is widely used.

  Such tape winding clamps and band clamps require separate parts such as tapes and jigs, and also require cutting and removing operations, resulting in an increase in the number of parts and the number of work steps. Therefore, there is already known a clamp that does not require a separate part, and does not need to cut and remove the part when the wire harness is fixed, and has a reduced work man-hour at the time of attachment (for example, Patent Document 1). reference).

  In such a clamp, as shown in FIG. 8, a pair of insertion locking portions 120, 130 erected from both ends of the annular belt portion 110 are provided, and the pair of insertion locking portions 120, 130 are provided at both end edges. Shaft plate portions 121 and 131 that protrude further, blade portions 122 and 132 that are folded outward from the tips of the shaft plate portions 121 and 131, and a lock that is formed in an inverted L-shaped cross section inward from the shaft plate portions 121 and 131. Parts 123 and 133 and locked parts 124 and 134 in which the upper end parts of the shaft plate parts 121 and 131 are cut out, and the shaft plate parts 121 and 131 are accommodated in the annular belt part 110. The locking portions 123 and 133 are engaged with the locked portions 124 and 134 by bringing them closer to each other.

JP 2004-104924 A

  However, in the clamp as described above, the annular belt portion 110 is configured to allow bending to such an extent that the shaft plate portions 121 and 131 approach each other. Therefore, when the wire harness has a different diameter, the diameter of the wire harness is different. A clamp having an annular band portion 110 having a diameter corresponding to the above has to be prepared, and the problem of lacking in versatility remains.

  Further, even if the annular belt portion 110 can be deformed like the band clamp described above, the shaft plate portions 121 and 131 remain as they are, and therefore cannot be adapted to changes in the diameter of the wire harness and lack general versatility. The problem still cannot be solved.

  The present invention has been made to solve the above-described problems, and can easily fix a wire harness to a panel and improve versatility in response to a change in the diameter of the wire harness. An object is to provide a clamp that can be used.

  In order to achieve the above object, the clamp according to the present invention has a pair of insertion locks projecting toward the outer side in the radial direction at the both ends of the band portion that can be bent in a substantially annular shape so as to surround the wire harness. A clamp that inserts the pair of insertion locking portions into the through-holes of the panel so as to be prevented from coming off, provided on the inner surfaces facing each other of the pair of insertion locking portions and approaching each other A plurality of locking projections and locking recesses which are locked to each other, and a plurality of pairs of locking claws provided on the outer surface side of the pair of insertion locking portions and spaced apart in the insertion direction of the insertion locking portions, respectively When the pair of insertion locking portions are inserted into the through holes of the panel, any one of the pair of locking claw portions is locked to the panel.

  With this configuration, the clamp according to the present invention is configured to lock the locking projections and the locking recesses provided in the pair of insertion locking portions by bending the band portion in a substantially annular shape and surrounding the wire harness, Since the pair of locking claws are locked to the panel by inserting the insertion locking portion into the through hole of the panel, the wire harness can be easily fixed to the panel.

  The clamp according to the present invention changes the locking position of the plurality of pairs of locking claw portions spaced apart in the insertion direction of the insertion locking portion according to the diameter of the wire harness, Since the wire harness can be fixed to the panel even if the diameter changes, versatility can be improved.

  Moreover, the clamp which concerns on this invention WHEREIN: The said latching convex part and the latching recessed part may be provided with two or more so that it may mutually space apart in the insertion direction of the said insertion latching | locking part.

  With this configuration, the clamp according to the present invention can lock any one of a plurality of locking projections and locking recesses according to the diameter of the wire harness, so the clamp is attached to the wire harness. In this case, the wire harness can be surrounded more stably.

  ADVANTAGE OF THE INVENTION According to this invention, the clamp which can fix a wire harness to a panel easily and can improve versatility corresponding to the change of the diameter of a wire harness can be provided.

It is a perspective view which shows the conventional clamp.

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

  1 and 2 are views showing a clamp 10 according to the present embodiment. As shown in FIG. 1, the clamp 10 is positioned on both ends of the band portion 10 a and the band portion 10 a that can be bent in a substantially annular shape so as to surround the wire harness W, and as shown in FIG. And a pair of insertion locking portions 10b and 10c that protrude toward the outside in the radial direction when an annular shape is used.

  As shown in FIG. 3, the length L of the band portion 10a takes into consideration the maximum diameter and the minimum diameter of the wire harness W that can be assumed when the wire harness W is routed to the vehicle body, for example. The length is L.

  That is, in the case of the wire harness W to be routed to the vehicle body, the wire harness W is routed collectively from the various control units in the main direction and then branched at a plurality of locations to be used as a power supply line or a control signal line.

  Accordingly, the wire harness along the main direction has a large diameter due to the large number of wires. On the other hand, the branched wire harness has a small diameter because the number of wires is reduced.

  Therefore, if the same clamp 10 can be used in the routing of the group of wire harnesses 10, it is not necessary to prepare a plurality of types, and versatility can be improved.

  Therefore, in this embodiment, when the length L surrounds the wire harness W in consideration of both the maximum diameter routed along the main direction and the circumferential length at the branched minimum diameter. In this case, a length that can be fixed to the panel P described later is used.

  The clamp 10 is made of a bendable resin material (for example, PA66 resin = nylon (registered trademark)) or the like.

  The pair of insertion locking portions 10b, 10c includes a plurality of locking claw portions 11a, 11b, 11c, a plurality of locking claw portions 12a, 12b, 12c, a plurality of locking projections 13a, 13b, 13c, and a plurality of The locking recesses 14a, 14b, and 14c are integrally provided.

  The locking claw portions 11a, 11b, 11c, the locking claw portions 12a, 12b, 12c, the locking projections 13a, 13b, 13c, and the locking recesses 14a, 14b, 14c are only different in position. The same configuration is used for each of the shapes and the like.

  Therefore, in the following description, the locking claw portions 11a, 11b, and 11c are collectively referred to as the locking claw portion 11 and the locking claw portions 12a, 12b, and 12c are collectively referred to as the locking claw portion 12 as necessary. The locking projections 13a, 13b, and 13c are collectively referred to as the locking projection 13, and the locking recesses 14a, 14b, and 14c are collectively referred to as the locking recess 14.

  When the band portion 10a is bent in a substantially annular shape so as to surround the wire harness W, three locking claws 11 and 12 are provided on each surface on the outer surface side of each insertion locking portion 10b and 10c. ing.

  Each latching claw part 11a, 11b, 11c is spaced apart at equal intervals along the insertion direction of the insertion latching part 10b. Similarly, the latching claw portions 12a, 12b, and 12c are also provided apart from each other in the insertion direction of the insertion latching portion 10c. Here, the insertion direction means a direction in which the band portion 10a is bent in a substantially annular shape and the insertion locking portions 10b and 10c are inserted into through holes H of the panel P described later. In addition, although the latching nail | claw parts 11 and 12 illustrated what provided three each spaced apart along the insertion direction to the panel P, the applicable range which can be assumed similarly to the length L mentioned above, for example. The present invention is not limited to this.

  Further, the respective locking claws 11, 12 are provided so as to be at the same position in the insertion direction of each insertion locking part 10b, 10c, for example, with reference to the tip position of each insertion locking part 10b, 10c. ing. Accordingly, the locking claw portion 11a and the locking claw portion 12a, the locking claw portion 11b and the locking claw portion 12b, and the locking claw portion 11c and the locking claw portion 12c are paired with each other.

  For example, the position of the locking claw part 11a in the insertion locking part 10b in the insertion direction is the same as the position of the locking claw part 12a in the insertion locking part 10c in the insertion direction, and the band part 10a is substantially omitted. When the ring is curved, a pair of locking claws 11a and 12a are formed. The same applies to the locking claws 11b and 11c and the locking claws 12b and 12c.

  Further, the locking claws 11 and 12 move in the direction away from the insertion locking portions 10b and 10c toward the front side in the insertion direction, that is, from the tip of the insertion locking portions 10b and 10c to the rear side in the insertion direction. An inclined surface is provided integrally, and is configured to be easily inserted into the through hole H.

  When the band portion 10a is bent in a substantially annular shape so as to surround the wire harness W, there are three locking projections 13 and locking recesses 14 on the inner surfaces of the insertion locking portions 10b and 10c. It is provided one by one. Moreover, the latching convex part 13 and the latching recessed part 14 are located between each latching claw parts 11 and 12 along an insertion direction. In addition, although the latching convex part 13 and the latching recessed part 14 illustrated what provided three each spaced apart along the insertion direction to the panel P, for example, the length L mentioned above, each latching claw part, etc. Like 11 and 12, it is arbitrary depending on the scope of application that can be assumed, and the present invention is not limited to this.

  As shown in FIG. 4, the locking projection 13 protrudes from the inner surface side of the insertion locking portion 10 b when the band portion 10 a is bent so as to surround the wire harness W, and is substantially omitted from the insertion locking portion 10 b. The leg part 23a which stands | starts up vertically, and the nail | claw part 23b which was located in the front-end | tip of the leg part 23a and was formed in the arrowhead shape of one side are included.

  The leg portion 23a has a length equal to or greater than the thickness of the insertion locking portion 10c. Further, since the clamp 10 is a bendable resin, the leg portion 23a can also be elastically deformed.

  The claw portion 23b is formed to be tapered toward the distal end side, and can be locked to the locking recess 14 by having a thicker portion than the leg portion 23a. Therefore, the shape of the claw portion 23b is not particularly limited, such as a double-sided arrowhead shape or a spherical shape in addition to the one-sided arrowhead shape described above.

  The locking recess 14 penetrates from the inner surface side to the outer surface side of the insertion locking portion 10c, and is formed in a concave shape that is recessed so that the claw portion 23b can be locked on the outer surface side of the insertion locking portion 10c. ing.

  Each of the locking projections 13a, 13b, and 13c is provided at a position facing the locking claw portion 11 at an equal interval in the insertion direction of the insertion locking portion 10b. Similarly, each of the locking recesses 14a, 14b, and 14c is provided at a position facing the locking claw portion 12 at regular intervals in the insertion direction of the insertion locking portion 10c.

  Moreover, each latching convex part 13 and the latching recessed part 14 are each provided so that it may become the same position in the insertion direction of each insertion latching | locking part 10b, 10c. For this reason, the clamp 1 holds the curved posture of the band portion 10a by locking the locking projection 13 to the locking recess 14 when the band portion 10a is bent in a substantially annular shape.

  FIG. 5 is a diagram illustrating a state in which the clamp 10 is attached to the wire harness W. As shown in FIG. 5, the clamp 10 can be attached to the wire harness W by deforming the band portion 10 a so as to surround the wire harness W by curving the band portion 10 a in a substantially annular shape.

  Here, the clamp 10 is attached to the wire harness W so that the insertion locking portions 10b and 10c face the through holes H provided in the panel P such as a vehicle body. In addition, the clamp 10 holds all the locking projections 13 in the locking recesses 14, thereby holding the posture in which the band portion 10 a is deformed into a substantially annular shape for attachment to the wire harness W. The position of the wire harness W in the circumferential direction is held.

  FIG. 6 is a view showing a state in which the wire harness W is fixed to the panel P by the clamp 10. As shown in FIG. 5, the clamp 10 has the locking claw portions 11 a and 12 a on the back side of the panel P with the insertion locking portions 10 b and 10 c inserted toward the through hole H, and the edge of the through hole H. The wire harness W can be fixed to the panel P by being locked.

  With this configuration, the clamp 10 according to the present embodiment has the locking projection 13 and the locking recess provided on the pair of insertion locking portions 10b and 10c while the band portion 10a is bent in a substantially annular shape and surrounds the wire harness W. Since the pair of insertion claw portions 11a and 12a are locked to the panel P by inserting the pair of insertion locking portions 10b and 10c into the through holes H of the panel P in a state in which the 14 is locked to each other, The wire harness W can be easily fixed to the panel P.

  Here, when the wire harness W is a wire harness W1 having a large diameter, as shown in FIG. 7, in the clamp 10, the locking projections 13b and 13c are locked to the locking recesses 14b and 14c, respectively. By holding the posture in which the band portion 10a is deformed into a substantially annular shape and the circumferential position of the wire harness W1, the locking claw portions 11b and 12b are locked to the edge portion of the through hole H, thereby the wire harness W1. Is fixed to the panel P.

  Thus, the diameter of the wire harness W can be changed by changing the locking positions of the locking claws 11a, 11b, 11c and the locking claws 12a, 12b, 12c with respect to the panel P according to the diameter of the wire harness W. A narrowing action that substantially varies the length L of the band portion 10a corresponding to (peripheral length) can be provided.

  With this configuration, the clamp 10 according to the present embodiment changes the locking position of the locking claw portions 11a, 11b, 11c and the locking claw portions 12a, 12b, 12c with respect to the panel P according to the diameter of the wire harness. By doing so, the wire harness can be fixed to the panel P even if the diameter of the wire harness changes, so that it can have high versatility.

  Similarly, depending on the diameter of the wire harness W, by changing the locking positions of the locking projections 13a, 13b, 13c and the locking recesses 14a, 14b, 14c with respect to the wire harness W, the diameter (circumference) of the wire harness W is changed. A narrowing action that substantially changes the length L of the band portion 10a corresponding to (long) can be applied before being fixed to the panel P.

  With this configuration, in the clamp 10 according to the present embodiment, any one of the plurality of locking projections 13 and locking recesses 14 is locked to each other regardless of the diameter of the wire harness W (W1). When the clamp 10 is attached to the wire harness W (W1), the circumferential position of the wire harness W (W1) can be stably held in advance.

  Therefore, by using the locking projection 13 and the locking recess 14, the wire harness W (W 1) can be surrounded more stably.

  As described above, the clamp 10 according to the present embodiment includes the locking protrusions 13 provided on the pair of insertion locking portions 10b and 10c by bending the band portion 10a in a substantially annular shape and surrounding the wire harness W, and Since the locking recesses 14 are locked to each other and the pair of insertion locking portions 10b and 10c are inserted into the through holes H of the panel P, the pair of locking claws 11a and 12a are locked to the panel P. The wire harness W can be easily fixed to the panel P.

  In addition, the clamp 10 according to the present embodiment changes the pair of locking claws 11 and 12 locked to the panel P according to the diameter of the wire harness, so that the wire harness can be changed even if the diameter of the wire harness changes. Since the harness can be fixed to the panel P, it can have high versatility.

  In addition, the clamp 10 according to the present embodiment is configured such that any one of the plurality of locking projections 13 and locking recesses 14 is locked to each other regardless of the diameter of the wire harness. When attached to the wire harness, the circumferential position of the wire harness can be stably held.

  In addition, in this Embodiment, although the clamp 10 is the structure which has the three latching claw parts 11 and 12, it is not restricted to this, What is necessary is just a structure which has multiple.

  In the present embodiment, the locking claw portions 11 and 12 are provided at equal intervals in the insertion direction of the insertion locking portions 10b and 10c, respectively. Positions at which the claw portions 11 and 12 are paired, that is, positions of the locking claw portions 11a, 11b, and 11c in the insertion direction of the insertion locking portion 10b and insertion locking of the locking claw portions 12a, 12b, and 12c. If the positions of the portions 10c in the insertion direction are the same, the intervals between the locking claws 11a, 11b, 11c and the intervals between the locking claws 12a, 12b, 12c may be different.

  Further, in the present embodiment, the clamp 10 is configured to include the three locking projections 13 and the three locking recesses 14. The number may be the same as long as it has the same number.

  Further, in the present embodiment, the locking projections 13 and the locking recesses 14 are provided at equal intervals in the insertion direction of the insertion locking portions 10b and 10c, respectively. The position where each locking projection 13 and each locking recess 14 lock each other, that is, the position of each locking projection 13a, 13b, 13c in the insertion direction of the insertion locking portion 10b and each locking recess 14a, If the positions of the insertion locking portions 10c in the insertion direction of 14b and 14c are the same, the intervals between the locking projections 13a, 13b and 13c and the intervals between the locking claws 14a, 14b and 14c are respectively May be different.

  Moreover, in this Embodiment, although the latching convex part 13 and the latching recessed part 14 are provided in the position facing the latching claw parts 11 and 12, respectively, not only this but the band part 10a is substantially cyclic | annular. In this case, it is only necessary to be provided on the inner surface side of the insertion locking portions 10b and 10c.

  In addition, the separation distance in the insertion direction of each latching claw part 11a, 11b, 11c and each latching claw part 12a, 12b, 12c is determined in consideration of the thickness of the panel P. Further, the separation distance in the insertion direction of the locking projections 13a, 13b, 13c and the locking recesses 14a, 14b, 14c is the distance between the locking claw portions 11a, 11b, 11c and the locking claw portions 12a, 12b, 12c. It is the same as the distance.

  Therefore, even if there is a difference between the locking positions of the locking projections 13a, 13b, 13c and the locking recesses 14a, 14b, 14c, such as buttons on clothes, the locking claws 11a, 11b, The wire harness can be fixed to the panel P as it is only by changing the positions of the claw portions 12a, 12b, and 12c.
