Description

  The present invention relates to a wire fixing structure.

8 and 9 show the wire fixing structure disclosed in Patent Document 1 below.
As shown in FIG. 8, this wire fixing structure is configured such that a wire bundle 120 passing over a strip-like wire placing plate portion 111 formed on a substantially flat wiring board 110 is wire-loaded by a binding band 130. It is bound and fixed to the mounting plate portion 111.

  As shown in FIG. 9, the electric wire placing plate portion 111 is a band plate shape sandwiched between a pair of cutout grooves 113 extending in the electric wire laying direction (the arrow X1 direction in FIGS. 8 and 9) on the wiring board 110. It is a part of. The pair of cutout grooves 113 sandwiching the electric wire placement plate portion 111 and the communication groove 114 communicating with one end thereof form a U-shaped cutout 115 surrounding the three sides of the electric wire placement plate portion 111.

  The groove width W1 of the pair of cutout grooves 113 is set to be larger than the thickness dimension t1 of the band main body 131 of the binding band 130. Further, the groove width W2 of the communication groove 114 that allows the pair of cutout grooves 113 to communicate with each other is set to be larger than the width dimension Wb of the band body 131 of the binding band 130.

  As shown in FIG. 9, the binding band 130 is integrally formed with one end of the band main body 131 and a band-shaped band main body 131 that can be wound around the electric wire bundle 120 or the electric wire placing plate portion 111. A band locking portion 132.

  The band main body 131 has locking irregularities 131a formed on one side thereof at regular intervals in the length direction.

  The band locking portion 132 is engaged with a locking unevenness 131a on the inserted band main body 131 in the band insertion hole 132a through which the band main body 131 can be inserted, and restricts movement of the band main body 131 in the removal direction. An elastic locking projection (not shown) is provided.

  As described above, the band body 131 has a thickness dimension t1 set smaller than the groove width W1 of the notch groove 113, and is inserted into the pair of notch grooves 113 as shown in FIG. It can be hidden under the plate portion 111. Further, the band body 131 has a width dimension Wb set smaller than the groove width W2 of the communication groove 114, and the band body 131 bent in a substantially U shape is connected to the back side of the wiring board 110 from the communication groove 114. Can be pushed into.

  In the electric wire fixing structure described above, as shown in FIG. 9, if the hand is released from the binding band 130 with the band main body 131 hidden under the electric wire placing plate portion 111, the band main body 131 is bent.

JP-A-10-229283

  However, in the electric wire fixing structure of Patent Document 1, there is no means for restricting movement of the electric wire mounting plate portion 111 along the longitudinal direction with respect to the binding band 130 temporarily fixed to the electric wire mounting plate portion 111, and temporary fixing. When the binding band 130 is easily displaced in the longitudinal direction of the wire placing plate portion 111 due to contact with external equipment or the like, and the positional displacement in the longitudinal direction of the wire placing plate portion 111 is large, There was a possibility that the binding band 130 might fall off the electric wire placing plate portion 111.

  Therefore, when binding the wire bundle 120 to the wire placing plate portion 111, an operation for correcting the displacement of the attachment position of the binding band 130 is required, or an operation for reattaching the binding band 130 is required. Therefore, the electric wire bundle 120 cannot be efficiently fixed to the electric wire placing plate portion 111, or the electric wire bundle 120 cannot be fixed with high accuracy.

  Therefore, in Patent Document 1, as shown in FIG. 10, a protrusion 111b projecting in the width direction of the electric wire placing plate portion 111 is provided at the tip of the electric wire placing plate portion 111, or as shown in FIG. A technique has been proposed in which a protrusion 111 c that protrudes downward is provided at the tip of the mounting plate portion 111. These protrusions 111 b and 111 c restrict the movement of the band main body 131 hidden under the electric wire placing plate portion 111 toward the distal end side of the electric wire placing plate portion 111.

  However, as shown in FIG. 10 and FIG. 11, the band main body 131 is provided from the communication groove 114 to the lower surface side of the electric wire placing plate portion 111 in order to equip the tip of the electric wire placing plate portion 111 with the protrusions 111 b and 111 c. It becomes difficult to perform the operation of inserting, and there arises a problem that workability at the time of temporarily fixing the binding band 130 to the electric wire placing plate portion 111 is lowered.

  Therefore, an object of the present invention is to solve the above-mentioned problems, and when fixing an electric wire to the electric wire placing plate portion on the wiring board, the binding band can be simply temporarily fixed to the electric wire placing plate portion in advance. Another object of the present invention is to provide an electric wire fixing structure that can fix the electric wire efficiently and with high accuracy, because the binding band that is temporarily fixed is not likely to be displaced.

The above-described object of the present invention is achieved by the following configuration.
(1) An electric wire placing plate portion formed in a strip shape sandwiched between a pair of notch grooves extending in the direction of laying an electric wire on a substantially flat wiring board, and one end of a band body that can be inserted through the notch groove A bundling band provided with a band locking portion for locking the other end side of the band main body,
The electric wire passing over the electric wire placing plate portion is bound and fixed to the electric wire placing plate portion by the binding band in which the band main body is hidden under the electric wire placing plate portion from the pair of cutout grooves. Electric wire fixing structure,
The at least one notch groove of the pair of notch grooves is formed on an outer edge portion of the band main body that is curved opposite to the side edge of the electric wire placing plate portion under the electric wire placing plate portion. An electric wire fixing structure comprising a cutout portion into which the band main body enters by elastic restoring force.

  (2) The above-mentioned (1), characterized in that at least one side edge of the wire placing plate portion facing the notch groove is provided with a second notch portion that can interrupt the band body that binds the wires. Wire fixing structure as described in).

  According to the configuration of (1) above, the binding band is inserted through the wire placing plate portion inside the U-shaped bent portion in a state where the band main body is bent in the U-shape. When the band body is loosened when the band body reaches the wire fixing position, the band body moves outward in the width direction of the wire placing plate part by the elastic restoring force of the band body bending part. The cutout portion of the outer edge portion of the band is interrupted, and the band main body is in elastic contact with the outer edge portion of each notch portion and both side edge portions on the lower surface side of the wire placing plate portion. Therefore, even if the hand is released from the binding band, the binding band is in a temporarily locked state in which the binding band is locked to the electric wire placing plate portion by elastic contact due to the elastic restoring force.

  Then, the binding band in the temporarily locked state is restricted from moving in the direction along the longitudinal direction of the electric wire placing plate part by the engagement between the band main body and the notch part.

  Therefore, even if the binding band in the temporarily locked state receives an external force in the direction along the longitudinal direction of the electric wire placing plate part due to contact with external equipment or the like, the binding band is displaced in the longitudinal direction of the electric wire placing plate part. Is prevented.

  Therefore, when fixing the electric wire to the electric wire mounting plate on the wiring board, there is no need to correct the positional deviation of the temporarily fixed binding band or to temporarily fix the binding band. Thus, the electric wire can be fixed to the electric wire placing plate portion. Further, since the temporary fixing position of the binding band does not shift, the fixing position of the electric wire is not shifted, and the electric wire can be fixed with high accuracy.

  According to the configuration of (2) above, when the outer diameter of the electric wire or electric wire bundle bound by the binding band is smaller than the standard, the band body is equipped on the side edge of the electric wire placing plate portion when the binding band is tightened. By entering into the 2nd notch part which was made, it can fix firmly also with respect to a small diameter electric wire or electric wire bundle. That is, by providing the second notch on the side edge of the electric wire placing plate portion, the range of the diameter of the electric wire or electric wire bundle that can be bundled with the binding band is widened, and even with the electric wire placing plate portion having the same width, It becomes possible to fix a diameter electric wire or electric wire bundle.

  According to the electric wire fixing structure of the present invention, when the electric wire is fixed to the electric wire placing plate portion on the wiring board, the binding band can be easily temporarily fixed to the electric wire placing plate portion in advance, and the electric wire is fixed temporarily. The binding band is less likely to be displaced, and the electric wire can be fixed efficiently and with high accuracy.

  The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading through a mode for carrying out the invention described below (hereinafter referred to as “embodiment”) with reference to the accompanying drawings. .

FIG. 2B is a front view of the binding band used in the first embodiment, FIG. 2B is a view of the binding band shown in FIG. 2A, and FIG. 3 is an electric wire placing plate in the first embodiment of the present invention. 4 is a perspective view of a pair of notch grooves sandwiching the wire portion and the electric wire placing plate portion, FIG. 4 is a plan view of the electric wire placing plate portion and the pair of notched grooves shown in FIG. 3, and FIG. 5 is a diagram of the first embodiment of the present invention. It is a perspective view of the state where the binding band was temporarily locked to the electric wire placing plate part.

  As shown in FIG. 1, the electric wire fixing structure of this embodiment is a structure in which the electric wire 40 is fixed to the electric wire placing plate portion 31 on the wiring board 30 using the binding band 20.

  The binding band 20 is an integrally molded product of resin, and is integrally formed at one end of the band main body 21 and a band-shaped band main body 21 that can be wound around the electric wire 40 or the electric wire placing plate portion 31 as shown in FIG. A band locking portion 22.

  The band main body 21 is a belt-like body having flexibility that can be wound around the electric wire 40 or the electric wire placing plate portion 31, and locking irregularities 211 are formed on one side thereof at regular intervals in the length direction. . The band main body 21 can be inserted through a notch groove 32 described later.

  The band locking portion 22 is engaged with a locking unevenness 211 on the inserted band main body 21 in a band insertion hole 221 through which the band main body 21 can be inserted, thereby restricting movement of the band main body 21 in the removal direction. An elastic locking projection (not shown) is provided.

  As shown in FIG. 1, the binding band 20 is inserted into the band insertion hole 221 of the band locking portion 22 when the distal end side of the band main body 21 that surrounds the outer periphery of the electric wire placing plate portion 31 and the electric wire 40 is inserted. 21 is locked by the elastic locking protrusions in the band locking portion 22 to restrict the movement of the band main body 21 in the pulling direction (arrow Y1 direction in FIG. 1). It will be in the state bound to the electric wire mounting board part 31. FIG.

  The wiring board 30 is a substantially flat plate material used for a casing or a vehicle body of a device in which an electric wire is routed.

  As shown in FIGS. 3 and 4, the electric wire placing plate portion 31 has a width W3 sandwiched between a pair of cutout grooves 32 extending in the electric wire laying direction (the arrow X2 direction in FIG. 3) on the wiring board 30. It is a strip-shaped part. In the case of the present embodiment, the width W3 of the electric wire placing plate portion 31 is set to be slightly larger than the outer diameter of the electric wire 40 placed thereon.

  Each notch groove 32 has a groove width W5 (see FIG. 4) larger than a thickness dimension t5 (see FIG. 2B) of the band body 21 so that the band body 21 of the binding band 20 can be inserted therethrough. Is set.

  In the case of the present embodiment, it is assumed that the root portion of the electric wire placing plate portion 31 is a normal electric wire fixing position Pk (see FIG. 4) for binding the electric wires 40.

  As shown in FIG. 5, the electric wire fixing structure of the present embodiment is configured such that the band main body 21 is embedded in the electric wire mounting plate portion 31 by the binding band 20 in which the band main body 21 is hidden under the electric wire mounting plate portion 31 from the pair of cutout grooves 32. The electric wire 40 passing above is bound and fixed to the electric wire placing plate portion 31.

  In the case of the present embodiment, each notch groove 32 includes a notch portion 322 in an outer edge portion 321 that faces the side edge of the electric wire placing plate portion 31. As shown in FIG. 5, the notch 322 is a recess into which the band main body 21 enters due to the elastic restoring force of the band main body 21 that is curved under the electric wire placement plate 31. The notch 322 has a width dimension W6 larger than the width dimension Wb of the band main body 21. Further, the notch portion 322 is provided at a position facing the wire fixing position Pk on the wire placing plate portion 31.

  In the case of the electric wire fixing structure of the first embodiment described above, the binding band 20 has the electric wire placing plate portion 31 inside the U-shaped bent portion in a state where the band main body 21 is bent in the U shape. Inserted. When the bending of the band main body 21 is loosened when the band main body 21 reaches the electric wire fixing position Pk, the band main body 21 is directed outward in the width direction of the electric wire placing plate portion 31 by the elastic restoring force of the bending portion of the band main body 21. The band main body 21 is elastically brought into contact with the outer edge of each notch 322 and both side edges on the lower surface side of the electric wire placing plate part 31 by interrupting the notch 322 of the outer edge 321 of the notch groove 32. It becomes a state. Therefore, even if the binding band 20 is released, the binding band 20 is in a temporarily locked state in which the binding band 20 is locked to the wire placing plate portion 31 by elastic contact due to elastic restoring force.

  The binding band 20 in the temporarily locked state is restricted from moving in the direction along the longitudinal direction of the wire placing plate portion 31 by the engagement between the band main body 21 and the cutout portion 322.

  Therefore, the binding band 20 in the temporarily locked state is positioned in the longitudinal direction of the electric wire placement plate portion 31 even if it receives external force in the direction along the longitudinal direction of the electric wire placement plate portion 31 due to contact with external equipment or the like. Misalignment is prevented.

  In addition, since there is no protrusion at the front end of the wire placing plate portion 31 that becomes an obstacle when the band main body 21 is inserted, the wire placing plate portion 31 is bent in the U-shaped wire placing plate portion 31. It is possible to easily carry out the insertion.

  Therefore, when the electric wire 40 is fixed to the electric wire placing plate portion 31 on the wiring board 30, an operation for correcting the positional deviation of the temporarily fixed binding band 20 and an operation for temporarily fixing the binding band 20 become unnecessary. The electric wire 40 can be efficiently fixed to the electric wire placing plate portion 31 by the binding band 20. Moreover, since the temporary fixing position of the binding band 20 is not displaced, the fixing position of the electric wire 40 is not shifted, and the electric wire 40 can be fixed with high accuracy.
