Description

Technical Field

[0001] The present invention relates to a bundling member for bundling and holding a long wiring material. Background Art

[0002] When wiring a long wiring material such as a wiring harness in a vehicle, each fixture (bundling member) that bundles and holds the wiring material at a predetermined position in the length direction is fixed to each position on the vehicle body side (see Patent Documents 1 to 4). Such fixtures include a strip type and a belt type. The strip type fixture bundles and holds the wiring harness by winding a separate strip together with a plate-shaped sleeve portion integrally formed with the fixture around the wiring harness. The belt type fixture winds the wiring harness with a belt integrally formed with the fixture, and inserts the belt into a belt buckle formed at the end of the belt base, thereby bundling and holding the wiring harness.

[0003] In recent years, the development of an automatic bundling device for automatically bundling wiring materials such as wiring harnesses to such fixtures has been studied. In this case, the fixture used is not of the strip type but of the belt type. In the case of the strip type, it is suitable for manual work and difficult to automate by a device.

[0004] Incidentally, if Figure 10 and Figure 11 the strip type fixture 101 (strip 101T) shown in Figure 12 and Figure 13 is compared with the belt type fixture 102 (belt portion 102A) shown in Figure 11 and Figure 13 , the strip type has the advantage that there is no belt buckle portion 102B, and accordingly, the height can be made lower. That is, when fixed to the vehicle body side panel 300, the fixture with a low height can dispose the vehicle body side panel 300 closer to the wiring harness 200 at a distance h (see Figure 11 and Figure 13 ). Therefore, the space S on the wiring harness 200 side can be enlarged (reference numeral 400 is a structure inside the vehicle compartment). Therefore, the degree of freedom of the wiring path can be increased. In addition, even if it is assumed that there is a structure 400 (surrounding object) in the space S, a sufficient width j of clearance can be ensured between the structure 400 and the wiring harness 200, so it is difficult to cause interference or the like.

[0005] In addition, in the belt type fixture 102 (see Figure 12 and Figure 13 ), in the case of a structure in which an elastic locking piece that prevents detachment when inserted into the belt buckle portion 102B is in contact with the wiring harness 200 on the front end side, when bundling with the belt 102A, the elastic locking piece is pressed by the wiring harness 200 and becomes difficult to flex, and there is also a problem that it takes labor and time to insert the belt 102A into the belt buckle portion 102B.

[0006] Prior Art Documents Patent Documents Patent Document 1: Japanese Unexamined Patent Application Publication No. 2007-166781 Patent Document 2: Japanese Unexamined Patent Application Publication No. 2017-44243 Patent Document 3: Japanese Patent No. 6445309 Patent Document 4: Japanese Unexamined Patent Application Publication No. 2011-202777 Summary of the Invention Problems to be Solved by the Invention The problem of the present invention is to provide a belt-shaped bundling member in which the height of the buckle portion is lower than before, and it is difficult for a wire harness to interfere with the elastic locking piece when bundling a belt.

[0007] Means for Solving the Problems and Effects of the Invention The bundling member for solving the above problems integrally includes a belt portion that winds around the outer periphery of a long strip-shaped wiring material, and a buckle portion that inserts and fixes the belt portion from its front end into a belt insertion hole. Among them, The buckle portion has an upper surface portion on the upper side of the belt insertion hole, a lower surface portion on the lower side of the belt insertion hole, and side surface portions on the left and right sides of the belt insertion hole. The lower surface portion has an elastic locking piece that extends from the entrance side to the exit side of the belt insertion hole, is supported in a cantilever state with the extended front end being a free end, and a locking claw that protrudes upward is formed on the free end side. In the belt portion, locking grooves are continuously formed in a form arranged along the belt length direction, and when inserted into the belt insertion hole from the entrance side, the locking grooves lock the locking claw in a direction opposite to the belt insertion direction. The base end of the belt portion branches to the left and right with a gap therebetween, and is separately connected to the lower surface (bottom surface) of the buckle portion on the left and right sides. The elastic locking piece is configured to extend in a form that crosses the connection position of the belt portion and the lower surface of the buckle portion in the belt insertion direction, and elastically deforms downward at the free end side and enters the gap.

[0008] According to the above structure, the wire harness to be bundled and held is arranged on the lower surface (bottom surface) of the buckle portion and is biased toward the entrance side of the belt insertion hole. The elastic locking piece extends from the entrance side to the exit side of the belt insertion hole, crosses the connection position of the belt portion, the fixed end side is located on the entrance side of the connection position of the belt portion, and the main flexural free end side (locking claw side) is located on the exit side of the connection position of the belt portion. Therefore, the elastic locking piece is not easily interfered with by the wire harness to be bundled and held, and in particular, it is not easy to hinder the flexure of the free end side.

[0009] In addition, according to the above structure, when the elastic locking piece elastically deforms in a manner of deflecting laterally downward at its free end, it enters the gap formed between the branches at the base end of the belt portion. This entry is protected in a form of being clamped by the shape of the branches at the base end of the belt portion (two-strand shape), so it is not easily interfered with by the wire harness being bundled and held. Thus, it is possible to ensure the lateral downward deflection of the free end of the elastic locking piece.

[0010] The lowermost surface of the buckle portion can include the lower surface of the elastic locking piece and be formed in a coplanar manner.

[0011] According to the above structure, the elastic locking piece deflects downward the outer space below the buckle portion across the position of the lower surface of the buckle portion. Conventionally, a space for the elastic locking piece to deflect is ensured inside the buckle portion (between the upper and lower widths from the lower surface to the upper surface of the buckle portion) (refer to Figure 4 of Patent Document 2, Figure 4 of Patent Document 3, Figure 3 of Patent Document 4). Even when the elastic locking piece is in a deflected state, it is clamped and protected by the left and right wall portions of the buckle portion. However, due to the existence of this space, it is impossible to make the buckle portion thinner. According to the above structure, since the outer space below the buckle portion is used as the space for the elastic locking piece to deflect, it is possible to make the lower surface portion of the buckle portion thinner. And when the elastic locking piece deflects, it enters the inside of the two-strand shape at the base end of the belt portion, so it is not easily interfered with by the wire harness being bundled and held, and it is possible to ensure the lateral downward deflection of the free end.

[0012] The bundling member includes an engaging portion for assembling to the vehicle body side (other member). Two buckle portions are arranged and formed in a manner such that the belt insertion directions are parallel, and the belt portions extend downward from the respective lower surfaces of the buckle portions. The engaging portion can be formed in a manner of protruding upward at a plate-shaped connecting portion that connects the opposing side surfaces of the two buckle portions.

[0013] According to the above structure, like a strip-shaped clamp (refer to Figure 10 and Figure 11 ), when bundling the wire harness at two positions sandwiching the engaging portion, the wire harness can be arranged in a straight line between these two positions. Thus, the wire harness between these two positions can be bundled and held in a straight line manner. Therefore, in this straight line section, it is possible to avoid interference with other structural parts due to deflection (such as the contact between the vehicle body side member 300 (protrusion 301) and the wire harness 200 near A shown in Figure 12 and Figure 13 ). In addition, in this straight line section, the connecting portion is arranged opposite to the vehicle body side, so it is possible to protect the contact between the vehicle body side and the wire harness through the connecting portion.

[0014] A convex portion is formed to protrude outward on the side surface portion.

[0015] According to the above structure, the convex portion can be set as a gripping portion gripped by an automatic strapping device. By gripping the convex portion in a form of fitting the gripping portion, the position and posture of the strapping member in the gripped state can be made constant.

Detailed implementation mode

[0030] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0031] The binding member 1 integrally has a base portion and a wiring material binding portion. The binding member 1 may also integrally have an other member fixing portion, a base portion, and a wiring material binding portion. In the case of integrally having an other member fixing portion, the binding member 1 has an other member fixing portion protruding from the first side of the base portion, and a wiring material binding portion is formed on the second side of the base portion opposite to the first side.

[0032] As Figure 1 and Figure 2 shown, the binding member 1 of the first embodiment is a belt-type clamp 1A as follows: having a belt portion 4 (binding portion) that winds around the outer periphery of a long strip-shaped wiring material 200 (refer to Figure 3 and Figure 4 ) as the wiring material binding portion, having an anchoring portion 2 (engaging portion) for assembling to the vehicle body side as the other member fixing portion, and having a buckle portion 3 (binding fixing portion) provided at the base end of the belt portion 4 and fixing the front end side of the belt portion 4 by inserting it through the strap insertion through-hole 3h as the base portion 5. The wiring material 200 is a wire harness in which a plurality of wirings such as signal lines and power lines are bundled.

[0033] In addition, in the present invention, the bundling member 1 is not limited to the belt clamp 1A, and any belt-shaped bundling member having a belt portion 4 and a buckle portion 3 may be used. In addition, the wiring material 200 is not limited to a wire harness, and may be a long strip-shaped wiring material different therefrom.

[0034] As Figure 1 and Figure 2 shown, two buckle portions 3 are arranged in a form parallel to the belt insertion direction I3, and corresponding belt portions 4 are formed to extend downward from their respective lower surfaces 3b. The anchoring portion 2 protrudes upward from the center of the plate-shaped connecting portion 6 that connects the opposing side surfaces 3c (see Figure 5 ) of the two buckle portions 3 to form an upward direction as an insertion direction (assembly direction) for assembling to the vehicle body side. The connecting portion 6 is included in the base portion 5 together with the two buckle portions 3, 3.

[0035] Each buckle portion 3 has a substantially rectangular parallelepiped shape, and the substantially rectangular parallelepiped shape has an upper surface portion 3A of the upper inner wall forming the belt insertion hole 3h (see Figure 5 and Figure 6 ), a lower surface portion 3B of the lower inner wall forming the belt insertion hole 3h, and side surface portions 3C, 3C of the left and right inner walls forming the belt insertion hole 3h. The belt insertion hole 3h is formed to penetrate from the front (entrance) to the back (exit) of the buckle portion 3. The belt insertion direction I3 of the belt insertion hole 3h here is orthogonal to the vertical direction Z1 and the horizontal direction X1 of the belt clamp 1A.

[0036] Each buckle portion 3 has a belt portion 4 formed to extend downward from the lower surface portion 3B (lower surface 3b). The anchoring portion 2 is formed to protrude upward from the upper surface portion 3A (upper surface 3a) of the buckle portion 3 in a form with the upward direction as an insertion direction for assembling to the vehicle body side.

[0037] The anchoring portion 2 is a known insertion fixing portion that is inserted into the through hole 100h of the plate material 100 (for example, a vehicle body panel) shown in Figure 4 and is fixed against detachment. The anchoring portion 2 is not limited to this shape, and may be other shapes corresponding to the assembly object side.

[0038] One of the side surface portions 3C, 3C of each buckle portion 3 has a convex portion 3P (clamping convex portion) formed to protrude outward. Here, convex portions 3P are respectively formed on the two outer side surfaces 3c (see Figure 5 ) of the base portion having a horizontal arrangement structure arranged in the order of the buckle portion 3, the connecting portion 6, and the buckle portion 3. The convex portion 3P is formed in a shape that restricts the position change and posture change of the convex portion when it is fitted from the outside through the corresponding concave shape portion.

[0039] As Figure 6As shown, the lower surface portion 3B of each buckle portion 3 has an elastic locking piece 3BK extending from the entrance side ( Figure 6 right side) of the belt insertion through-hole 3h toward the exit side ( Figure 6 left side). The elastic locking piece 3BK is supported in a cantilever state such that the extended front end is a free end. A locking claw 3k protruding upward is formed on the free end side of the elastic locking piece 3BK. Here, in the region below the belt insertion through-hole 3h of the lower surface portion 3B, cuts extending from the exit side toward the entrance side of the belt insertion through-hole 3h are formed side by side in the left-right direction X1, and the elastic locking piece 3BK is formed between these cuts (refer to Figure 2 ).

[0040] As Figure 6 shown, the lowermost surface 3b0 in the lower surface 3b of each buckle portion 3 (lower surface portion 3B) is formed coplanar including the lower surface 3bk of the elastic locking piece 3BK.

[0041] Each belt portion 4 has a locking groove 4k that locks to the locking claw 3k when the belt is inserted into the belt insertion through-hole 3h from the entrance side. The locking groove 4k is a concave portion of unevenness continuously formed in a form arranged in the belt length direction (along the belt length direction).

[0042] In addition, Figure 6 only the locking groove in the vicinity of the section where the locking groove 4k in

[0043] As Figure 5 shown, the base end of each belt portion 4 branches to the left and right with a gap 4h therebetween, and is separately connected to the lower surface 3b (also referred to as the bottom surface) of the corresponding buckle portion 3 on both the left and right sides (left-right direction X1). That is, the base end portion 4B of the belt portion 4 forms a branched shape portion that branches into two strands (Y-shaped) toward the base end side.

[0044] As Figure 6 shown, the elastic locking piece 3BK of each buckle portion 3 is arranged to extend from the entrance side to the exit side of the belt insertion through-hole 3h so as to cross the connection position C4 with the lower surface portion 3B (lower surface 3b) of the belt portion 4 in the belt insertion direction I3, and enters the gap 4h when elastically deformed downward on the free end side ( Figure 6 left side).

[0045] The use of Figure 6 to explain the fixing of the belt portion 4 to the buckle portion 3.

[0046] The belt portion 4 is annularized by inserting it into the belt insertion through-hole 3h from the entrance side (refer to Figure 3 and Figure 4). The belt portion 4 with the insertion through-hole 3h is inserted from the entrance side and receives the locking claw 3k of the belt buckle portion 3 in the locking grooves 4k arranged along the belt length direction. However, by pressing in the belt insertion direction I3, the free end side (the locking claw 3k side) of the elastic locking piece 3BK is deflected downward ( Figure 6 lower side) to pass over the locking claw 3k, and the insertion is performed by repeating this operation. Then, when this advancement (insertion) stops, any one of the locking grooves 4k arranged along the belt length direction receives the locking claw 3k and becomes a state where they (4k, 3k) are locked in the direction opposite to the belt insertion direction I3, whereby the belt portion 4 becomes a state of being fixed against detachment relative to the belt buckle portion 3 (a state where detachment in the direction opposite to the belt insertion direction I3 is prevented).

[0047] When the belt portion 4 is formed into a loop as Figure 4 shown, a long strip-shaped wiring material 200 is arranged on the inner peripheral side thereof, and on this basis, the belt insertion through-hole 3h is inserted, whereby the wiring material 200 can be more firmly bundled and held. As Figure 6 shown, the bundled and held wiring material 200 is arranged on the entrance side ( Figure 6 right side) of the belt insertion through-hole 3h with respect to the lower surface 3b (bottom surface) of the belt buckle portion 3, being biased.

[0048] As Figure 6 shown, the elastic locking piece 3BK extends from the entrance side to the exit side of the belt insertion through-hole 3h, passing over the connection position C4 of the belt portion 4, and the main free end side (including the locking claw 3k) that is deflected exists on the exit side ( Figure 6 left side) of the connection position C4 of the belt portion 4. Therefore, the free end side of the elastic locking piece 3BK is not easily interfered with by the bundled and held wiring material 200.

[0049] In addition, when the elastic locking piece 3BK is elastically deformed in Figure 6 such a manner that the free end side is deflected downward, it enters the gap 4h provided at the base end portion 4B of the belt portion 4 (refer to Figure 6 the dashed line). This entry is ensured by the branched shape (two-strand shape) of the base end portion 4B of the belt portion 4.

[0050] In the first embodiment, as Figure 3 shown, there is a set of a belt portion 4 and a belt buckle portion 3 on each of the left and right sides of the anchoring portion 2. Therefore, when bundling the wiring material 200 using these two, the wiring material 200 is held in a straight line in the interval between them in a form opposed to the linear connecting portion 6.

[0051] The first embodiment of the present invention has been described above, but this is only an example, and the present invention is not limited thereto. Various changes such as addition and omission can be made based on the knowledge of those skilled in the art as long as the gist of the technical solution is not deviated from.

[0052] As Figure 7 and Figure 8 shown, the bundling members 1 of the second and third embodiments are the same as those of the first embodiment, and are the belt clamps 1B and 1C having a belt portion 4 as a wiring material bundling portion, an anchoring portion 2 as a fixing portion for other members, and a buckle portion 3 as a base portion.

[0053] In the belt clamp 1B of the second embodiment, as Figure 7 shown, there is no connecting portion 6, and the buckle portion 3 and the belt portion 4 are configured in the same manner as in the first embodiment. The anchoring portion 2 is formed to protrude upward from the upper surface portion 3A of the buckle portion 3. Protrusions 3P protruding outward are formed symmetrically on the left and right side surfaces 3c, 3c of the buckle portion 3.

[0054] As Figure 8 shown, in the belt clamp 1C of the third embodiment, the anchoring portion 2 is formed to protrude upward at one end of the connecting portion 6, and is connected to the side surface 3c of the buckle portion 3 at the other end. This connection is the same as in the first embodiment. The buckle portion 3 and the belt portion 4 are also the same as in the first embodiment. At one end of the connecting portion 6 of the third embodiment, a protrusion 3Q protruding outward is provided at its front end. The protrusion 3Q is formed symmetrically in a position symmetrical to the protrusion 3P protruding outward from the side surface 3c of the buckle portion 3 on the other end side.

[0055] As Figure 9 shown, the bundling member 1 of the fourth embodiment is configured in the same manner as the second embodiment, but there is no bundling band 1D (bundling band) for the anchoring portion 2 to be assembled to the vehicle body side. The buckle portion 3 and the belt portion 4 are configured in the same manner as in the first embodiment, and protrusions 3P protruding outward are formed symmetrically on the left and right side surfaces 3c, 3c of the buckle portion 3.
