The branch protection member BM may be formed so as to conform to the Y branch, or may be formed so as to conform to the T branch. In the present embodiment, the branch protection member BM is fixed to the swivel frame via the binding band fixing tool WF and the nut. That is, the cable tie fixture WF is configured so that the branch protection member BM can be fixed.

Next, the fixing structure of the wire harness WH will be described with reference to FIG. FIG. 3 is a diagram showing a fixed structure of the wire harness WH. Specifically, FIG. 3A is an enlarged view of the region R1 surrounded by the broken line in FIG. 2, and shows the connector CN1 which is an example of the connector CN and its periphery. FIG. 3B is an enlarged view of the region R2 surrounded by the broken line in FIG. 2, and shows the branch portion protection member BM and its periphery. FIG. 3C is an enlarged view of the region R3 surrounded by the broken line in FIG. 2, and shows the connector CN2 and its periphery, which is another example of the connector CN.

With reference to FIG. 3A, the wire harness WH is fixed to the swivel frame by three cable tie fixtures WF (cable tie fixtures WF1 to cable tie fixtures WF3). Further, the wire harness WH1 which is a part of the wire harness WH and the wire harness WH2 which is another part of the wire harness WH are connected by the connector CN1.

Specifically, the connector CN1 includes a male connector MCN attached to one end of the wire harness WH1 and a female connector FCN attached to one end of the wire harness WH2.

The wire harness WH1 is bundled by a binding band TB (binding band TB1), and is fixed to the swivel frame via a binding band fixing tool WF (binding band fixing tool WF1) and a nut NT (nut NT1). ..

The female connector FCN is fixed to the swivel frame via a binding band fixing tool WF (binding band fixing tool WF2) and a nut NT (nut NT2). In the present embodiment, the male connector MCN is fixed to the swivel frame via the female connector FCN, and therefore is not attached to the cable tie fixture WF2.

The wire harness WH2 is bundled by a binding band TB (binding band TB2), and is fixed to the swivel frame via a binding band fixing tool WF (binding band fixing tool WF3) and a nut NT (nut NT3). ..

More specifically, the wire harness WH0, which is a part of the wire harness WH, is branched into the wire harness WH1 and the wire harness WH3, which are other parts of the wire harness WH, at the branch portion protection member BM. .. The branch protection member BM is fixed to the swivel frame via the binding band fixing tool WF4 and the nut NT (nut NT4).

In the example shown in FIG. 3B, a part (protrusion) of the binding band fixture WF4 is formed in the center of the end face on the −Z side of the central portion CT of the branch protection member BM. By being fitted into a circular through hole (not shown), it is detachably connected to the branch protection member BM. However, the cable tie fixture WF4 and the branch protection member BM may be detachably connected to each other by any bonding method. For example, each of the binding band fixture WF4 and the branch protection member BM has a concave portion (or a convex portion) formed in the protrusion of the binding band fixture WF4 and a convex portion formed on the end surface of the branch protection member BM. (Or a recess) may be configured to fit.

Further, in the example shown in FIG. 3B, the binding band fixture WF4 is attached to the end face on the −Z side of the central portion CT having a substantially rectangular parallelepiped shape, but is attached to the end face on the + Y side of the central portion CT.

By using such a branch portion protection member BM, the operator can fix the wire harness WH to the swivel frame or the like via the binding band fixing tool WF4 at the branch portion of the wire harness WH, for example. Therefore, this configuration can increase the degree of freedom in design regarding the wiring of the wire harness WH.

With reference to FIG. 3C, the wire harness WH is fixed to the swivel frame by the cable tie fixture WF (cable tie fixture WF5).

Specifically, the wire harness WH4, which is a part of the wire harness WH, is folded back in the immediate vicinity of the connector CN2 to form the folded-back portion FD. Then, the wire harness WH4 is bundled together with a part of the connector CN2 by the binding band TB (binding band TB3) in a state where the portion extending in the + X direction from the folded portion FD is in contact with the upper surface of the connector CN2. This is to prevent the wire harness WH4 from swinging at the portion where the wire harness WH4 and the connector CN2 are connected (the root portion RT of the wire harness WH4) and damaging the root portion RT of the wire harness WH4. be. In this case, the binding band TB3 can also function as a first clamp (a clamp located closest to the connector CN2) for the wire harness WH4 extending from the connector CN2.

In the example shown in FIG. 3C, the connector CN2 is connected to a terminal connector (not shown) in the control unit of the engine 11. Then, the connector CN2 is fixed to the swivel frame via the adapter AD, the binding band fixing tool WF5, and the nut NT (nut NT5).

The adapter AD is a member for attaching the connector CN2 to the binding band fixture WF5. In the present embodiment, the adapter AD is configured to be removably fixed to the cable tie fixture WF5 and removably fixed to the connector CN2. However, the adapter AD may be integrated with the connector CN2. That is, the adapter AD may be integrally molded with the connector CN2 as a part of the connector CN2. In this case, the connector CN2 integrated with the adapter AD is configured to be removably fixed to the binding band fixture WF5.

Next, a configuration example of the cable tie fixture WF will be described with reference to FIG. FIG. 4 is a diagram showing a configuration example of the cable tie fixture WF. Specifically, FIG. 4A is a front view of the cable tie fixture WF, which is an example of the cable tie fixture WF. FIG. 4B is a perspective view of the cable tie fixture WFa. FIG. 4C is a perspective view of a slide rail type adapter ADa which is an example of the adapter AD attached to the cable tie fixture WFa. The cable tie fixture WFa can be used as the cable tie fixture WF1 to the cable tie fixture WF5 in FIG. The adapter ADa can be used as the adapter AD in FIG. 3 (C).

The cable tie fixture WFa is used to fix the cable tie TB (see FIG. 3A) to the structural member of the excavator 100. The structural member of the excavator 100 is, for example, a swivel frame or a house frame. The binding band TB is configured so that a plurality of long members can be bundled together. However, the cable tie TB may be used to fix one long member. The binding band TB may have a configuration in which it cannot be removed once it is bound (a configuration in which it cannot be rebound), or it may have a configuration in which it can be rebound. The long member is, for example, a wire harness WH, an electric cable, a urea water hose, a cooling water hose, a fuel hose, a hydraulic oil hose, or the like. The long member may or may not have flexibility. The house frame is a member that constitutes a building that is arranged on the swivel frame.

The cable tie fixture WFa is preferably made of a weather resistant material. The material having weather resistance is, for example, metal, synthetic resin, rubber, or the like. In this embodiment, the cable tie fixture WF is made of synthetic resin. Typically, the cable tie fixture WFa is formed by injection molding.

The cable tie TB is preferably made of a weather resistant material. In this embodiment, the binding band TB is made of synthetic resin. Typically, the cable ties TB are formed by injection molding. The cable tie TB may be integrated with the cable tie fixture WFa. That is, the binding band fixing tool WFa and the binding band TB may be integrally formed by injection molding or the like.

As shown in FIGS. 4 (A) and 4 (B), the cable tie fixture WFa is mainly composed of a retaining portion RP, a base portion BP, and a connecting portion CP.

The retaining portion RP is a part of the binding band fixing tool WFa, and is configured to be attached to the screw hole of the nut NT. In the present embodiment, the retaining portion RP made of synthetic resin is inserted into the screw hole of the nut NT. The retaining portion RP may be screwed into the screw hole of the nut NT.

Specifically, the retaining portion RP has a fitting structure that fits into the screw hole when it is inserted into the screw hole. Further, the retaining portion RP includes one or a plurality of convex portions PR having a structure for preventing the retaining portion RP inserted into the screw hole from coming off from the screw hole. The convex portion PR has, for example, a frustum shape, and is configured so that the outer peripheral end comes into contact with the inner wall of the screw hole and is deformed. In the present embodiment, the retaining portion RP includes the first inverted cone portion PR1 to the fifth inverted cone portion PR5, which are five convex portions PR. "Inverted cone" means a shape in which the radius of the upper base on the side closer to the base BP is larger than the radius of the lower base on the side farther from the base BP. The screw holes are formed so that their diameters are slightly smaller than the diameters of the first inverted cone portion PR1 to the fifth inverted cone PR5.

The base portion BP is a portion formed between the retaining portion RP and the connecting portion CP. In the present embodiment, the base BP functions as a stopper for preventing the retaining portion RP from being excessively inserted into the screw hole. Further, the base BP functions as a stopper for preventing foreign matter such as water from entering the inside of the screw hole from the outside. Therefore, the base BP has a diameter larger than the diameter of the retaining portion RP.

The connecting portion CP is a portion to which various members are connected. The various members are, for example, an adapter AD, a connector CN, a branch protection member BM, a binding band TB, and the like. In the present embodiment, the connecting portion CP includes the insertion portion IP and the fitting portion JP.

The insertion portion IP is configured to hold the binding band TB. In the present embodiment, the insertion portion IP includes an opening OP through which the binding band TB can be inserted, as shown in FIGS. 4 (A) and 4 (B). As shown in FIG. 4A, the opening OP includes the first opening OP1 and the second opening OP2. The shape of the end face (opening end face) of the opening OP of the insertion portion IP is a horizontally long rectangle, but may be a vertically long rectangle or a square. Alternatively, the shape of the open end face of the insertion portion IP may be another shape such as a circular shape, an elliptical shape, or a polygonal shape. As shown in FIG. 4B, when the shape of the opening end face of the insertion portion IP is a horizontally long rectangle, the opening OP of the insertion portion IP forms a substantially rectangular parallelepiped space in the insertion portion IP. That is, the inner wall of the insertion portion IP is configured to be a flat surface. This configuration is different from the case where the cross section of the binding band TB is rectangular and the inner wall of the insertion portion IP is a curved surface (for example, when a substantially cylindrical space is formed in the insertion portion IP). The deviation and rotation of the binding band TB in the space can be suppressed more effectively. This is because the gap formed between the inner wall of the insertion portion IP and the binding band TB can be reduced. The edge of the opening OP may be formed of a curved surface that has been subjected to R processing or the like so as not to damage the long member, the binding band TB, or the like.

The fitting portion JP is configured so that the adapter AD can be attached. The fitting portion JP is formed so as to be located on a side different from the side on which the retaining portion RP is located with respect to the base portion BP. In the present embodiment, the fitting portion JP is arranged on the + Z side of the base portion BP, and the retaining portion RP is arranged on the −Z side of the base portion BP. Specifically, the fitting portion JP is integrated with the insertion portion IP and is formed on the + Z side portion of the insertion portion IP.

In the present embodiment, the fitting portion JP is configured to have a groove portion GR. The groove GR is configured to mesh with the protrusion PT (see FIG. 4C) formed in the adapter ADa.

Specifically, the groove GR includes the first groove GR1 and the second groove GR2, and the protrusion PT includes the first protrusion PT1 and the second protrusion PT2. In the fitting portion JP, the first groove portion GR1 meshes with one of the first protruding portion PT1 and the second protruding portion PT2, and the second groove portion GR2 meshes with the other of the first protruding portion PT1 and the second protruding portion PT2. It is configured in.

The connecting portion CP has a substantially rectangular parallelepiped shape. The connecting portion CP is configured such that the groove portion GR in the fitting portion JP and the opening OP in the insertion portion IP are located on the same side. Specifically, the first groove portion GR1 and the first opening OP1 are formed on the + Y side side surface of the connecting portion CP, and the second groove portion GR2 and the second opening OP2 are formed on the −Y side side surface of the connecting portion CP. Has been done. However, the connecting portion CP may be configured so that the groove portion GR in the fitting portion JP and the opening OP in the insertion portion IP are located on different sides from each other. For example, the first groove portion GR1 may be formed on the + X side side surface of the connecting portion CP, and the second groove portion GR2 may be formed on the −X side side surface of the connecting portion CP. In this case, the groove GR may be formed at the same height as the opening OP (the same position in the Z-axis direction), and may be formed at a position lower than the opening OP (a position on the −Z side of the opening OP). It may be formed. Alternatively, the groove GR may be formed on three or more side surfaces of the four side surfaces of the connecting portion CP, or may be formed on only one of the four side surfaces of the connecting portion CP.

In the examples shown in FIGS. 4 (A) and 4 (B), the four edges of the upper surface TS of the connecting portion CP are configured to be angular, but R processing or the like is applied so that the edges are curved. You may be. The configuration including the curved portion can prevent one or a plurality of long members arranged so as to be in contact with the upper surface TS from coming into contact with the corner portion of the upper surface TS and being damaged. Alternatively, a closing member (not shown) covering the upper surface TS may be detachably attached to the upper surface TS. The upper surface of the closing member may be a flat surface, or may be configured to project in the + Z direction so that the central portion is the highest. In this case, the closing member may be made of a material softer than the material of the connecting portion CP. Further, only the central portion of the closing member may be made of a material softer than the other parts of the closing member. In this case, the closing member may be configured to engage the connecting portion CP as one of the adapter ADs.

As shown in FIG. 4C, the adapter ADa has a protrusion PT, a holding portion HK, and a claw portion RC. The protruding portion PT is configured to mesh with the groove portion GR formed in the fitting portion JP.

The holding portion HK is configured to hold a member connected to the adapter ADa. The member connected to the adapter ADa is, for example, a connector CN or a branch protection member BM. In the present embodiment, the holding portion HK is configured to hold the connector CN. Specifically, the holding portion HK includes a first holding portion HK1 and a second holding portion HK2. In this case, the connector CN has a structure corresponding to the holding portion HK. Specifically, the connector CN is formed with a protruding guide portion (not shown) having a prismatic shape with an inverted trapezoidal cross section.

Further, in the example shown in FIG. 4C, the second holding portion HK2 is configured to include the intrusion prevention portion ST. The intrusion prevention portion ST has a function of preventing the protruding guide portion of the connector CN from entering the holding portion HK from the −X side. That is, in the example shown in FIG. 4C, the operator can fit the protruding guide portion of the connector CN into the holding portion HK from the + X side, but the protruding guide portion is fitted into the holding portion HK from the −X side.

In the example shown in FIG. 4C, the intrusion prevention unit ST is arranged at the end on the −X side of the second holding portion HK2, but is arranged at the end on the + X side of the second holding portion HK2. Or it may be arranged at the end of the first holding portion HK1 on the −X side or the + X side. Further, the intrusion prevention unit ST may be arranged so as to form a pair at the -X side ends of the first holding unit HK1 and the second holding unit HK2, respectively, or the first holding unit HK1 and the first holding unit HK1 and the first holding unit ST may be arranged so as to form a pair. 2 The holding portion HK2 may be arranged so as to form a pair at each end on the + X side. The same applies to the intrusion prevention unit ST in each of the adapter ADb shown in FIG. 5 and the adapter ADc shown in FIG.

The claw portion RC is configured to prevent the member connected to the adapter ADa from falling off. In the present embodiment, the claw portion RC includes a first claw portion RC1 provided on the + X side edge portion of the upper surface UF and a second claw portion RC2 provided on the −X side edge portion of the upper surface UF. .. The claw portion RC is configured to mesh with a rectangular parallelepiped-shaped raised portion (not shown) on the end surface of the protruding guide portion of the connector CN.

Further, such a fall-out prevention structure may be formed between the connecting portion CP of the binding band fixing tool WFa and the adapter ADa. Further, as a fall-off prevention structure, a recess may be formed in the upper surface UF instead of the claw portion RC.

Next, another configuration example of the cable tie fixture WF will be described with reference to FIG. FIG. 5 shows a cable tie fixture WFb, which is another configuration example of the cable tie fixture WF. In FIG. 5, an adapter ADb, which is another example of the adapter AD, is attached to the cable tie fixture WFb. Specifically, FIG. 5A is a front view of the binding band fixture WFb to which the adapter ADb is attached. FIG. 5B is a perspective view of the cable tie fixture WFb to which the adapter ADb is attached.

The adapter ADc can be used as the adapter AD in FIG. 3 (C).

The adapter ADc shown in FIG. 6 is different from the adapter ADb shown in FIG. 5 in that it has a spear-shaped snap-fit portion SFc and has a cantilever-shaped snap-fit portion SF.

Specifically, the snap-fit portion SFc of the adapter ADc is configured to mesh with the opening TA of the fitting portion JP. More specifically, the snap-fit portion SFc includes a first snap-fit portion SFc1 and a second snap-fit portion SFc2. Each of the first snap-fit portion SFc1 and the second snap-fit portion SFc2 is formed so as to be elastically deformable, and when the adapter ADc is pressed against the upper surface of the connecting portion CP (insertion portion IP), it elastically deforms and opens. It is fitted in the TA.

Then, as shown in FIG. 6B, the adapter ADc is attached to the binding band fixture WFb so that the claw of the snap-fit portion SFc faces the opening OP side of the insertion portion IP. That is, in the adapter ADc, one claw of the first snap-fit portion SFc1 and one claw of the second snap-fit portion SFc2 face the first opening OP1 side (+ Y side), and the first snap-fit portion SFc1 The other claw of the second snap-fit portion SFc2 and the other claw of the second snap-fit portion SFc2 are attached to the binding band fixture WFb so as to face the second opening OP2 side (−Y side). However, the adapter ADc may be attached to the binding band fixture WFb so that the claws of the snap-fit portion SFc face the X-axis direction.

Next, still another configuration example of the cable tie fixture WF will be described with reference to FIG. 7. FIG. 7 shows a cable tie fixture WFc, which is still another configuration example of the cable tie fixture WF.

In the binding band fixture WFc shown in FIG. 7, a groove GR of the fitting portion JP is formed on a side surface other than the side surface on which the opening OP of the insertion portion IP is formed among the four side surfaces of the connecting portion CP. In that respect, it differs from the cable tie fixture WFa shown in FIG. In the binding band fixture WFa shown in FIG. 4, the groove GR of the fitting portion JP is formed on the same side surface of the four side surfaces of the connecting portion CP as the side surface on which the opening OP of the insertion portion IP is formed. ing.

Further, in the binding band fixing tool WFc shown in FIG. 7, since the groove portion GR is formed on the side surface other than the side surface on which the opening OP is formed, the height H1 of the connecting portion CP is fixed to the binding band shown in FIG. It is smaller than the height of the connecting portion CP in the tool WFa.

Further, in the binding band fixing tool WFc shown in FIG. 7, the connecting portion CP is configured such that the upper surface TS, which is a surface in contact with a plurality of long members bundled by the binding band TB, is a flat surface. This configuration can prevent the surface of the long member from being damaged by friction between the long member and the upper surface TS. In this configuration, the contact area between the long member and the upper surface TS is made larger than that in the case where the upper surface TS is not a flat surface, such as when a through hole, a convex portion, or a concave portion is formed in the upper surface TS. This is because the contact surface pressure can be reduced.

In the example shown in FIG. 7, the four edges of the upper surface TS are configured to be angular, but R processing or the like may be applied so that the edges are curved. The configuration including the curved portion can prevent one or a plurality of long members arranged so as to be in contact with the upper surface TS from coming into contact with the corner portion of the upper surface TS and being damaged.

Further, in the example shown in FIG. 7, the upper surface TS, the connecting portion CP, and the retaining portion RP are integrally formed, but the upper surface TS may be configured as another component (closing member). In this case, the upper surface of the cable tie fixture WF may be formed by the adapter ADa shown in FIG.

Further, the upper surface TS of the connecting portion CP may be made of a material softer than the material (for example, 66 nylon) constituting the other portion of the connecting portion CP, or may be made of a long member (for example, a corrugated tube). It may be made of the same material as the material that constitutes the surface (for example, PP (polypropylene) material), or it may be made of a material that is softer than the material that constitutes the surface of the long member (POM (polyacetal) material). It may be formed. For example, the material constituting the upper surface TS may be an elastomer. If an elastomer is used, the cable tie fixture WFc may be made by two-color molding. Further, the connecting portion CP may be made of not only the upper surface TS but the entire surface of the connecting portion CP with an elastomer, and the portion above (+ Z side) of the opening OP may be made of an elastomer. Even in this case, the base BP and the retaining portion RP are made of a harder material such as 66 nylon. However, the base BP may be made of an elastomer.

Next, still another configuration example of the cable tie fixture WF will be described with reference to FIG. FIG. 8 shows a cable tie fixture WFd, which is still another configuration example of the cable tie fixture WF.

The cable tie fixture WFd shown in FIG. 8 differs from the cable tie fixture WFd shown in FIG. 7 in that the sealing portion SL is provided on the lower surface (the surface on the −Z side) of the base BP.

The seal portion SL is configured to function as a stopper for preventing liquid such as water from entering the inside of the screw hole of the nut NT into which the binding band fixture WFd is inserted. In the example shown in FIG. 8, in the binding band fixture WFd, the sealing portion SL is made of elastomer, and the portion other than the sealing portion SL is made of 66 nylon. Specifically, the cable tie fixture WFd is manufactured by two-color molding.

In the example shown in FIG. 8, the seal portion SL has a disc portion DP and an annular edge portion AE. The diameter of the annular edge AE is configured to be larger than the diameter of the screw hole of the nut NT and smaller than the diameter of the nut NT. The annular edge portion AE is configured to project higher than the disc portion DP in the −Z direction. The disk portion DP may be omitted. That is, the seal portion SL may be composed of only the annular edge portion AE.

When the cable tie fixture WFd is inserted into the screw hole of the nut NT, the annular edge AE comes into contact with the end face of the nut NT and collapses, sealing between the lower surface of the base BP and the end face of the nut NT.

With this configuration, the seal portion SL can prevent water from entering the inside of the screw hole of the nut NT through the gap between the lower surface of the base portion BP and the end surface of the nut NT. Therefore, the seal portion SL can prevent the occurrence of rust on the end face of the nut NT and the inside of the screw hole even when the end face of the nut NT and the inside of the screw hole are not painted.

Further, the binding band fixture WFd integrally manufactured by two-color molding can reduce the manufacturing cost as compared with the case where the binding band fixture WFd is manufactured by manually assembling a plurality of parts. Further, the binding band fixing tool WFd integrally manufactured by two-color molding can more reliably prevent the sealing portion SL from falling off from the base BP, thus improving the quality of the binding band fixing tool WFd. Can be done.

As described above, the cable tie fixture WF as the wiring fixture according to the embodiment of the present invention can be attached to the retaining portion RP, the base BP connected to the end of the retaining portion RP, and the adapter AD. It has a fitting portion JP formed as described above. The fitting portion JP is located on a side different from the side on which the retaining portion RP is located with respect to the base portion BP.

With this configuration, various fixing objects such as a connector CN or a branch protection member BM can be attached to the binding band fixing device WF via the adapter AD, for example, as shown in FIG. Therefore, the operator can fix various fixing objects such as the connector CN or the branch protection member BM at the place where the nut NT into which the binding band fixing tool WF can be fitted is arranged. Further, the operator does not need to prepare a fixture dedicated to the connector CN or a fixture dedicated to the branch protection member BM. That is, in this configuration, the cable tie fixture WF can be a common component used for attaching various fixing objects. As a result, this configuration reduces the number of parts related to the arrangement of long members, reduces the manufacturing cost of parts related to the arrangement of long members, increases the degree of freedom in designing the arrangement of long members, or lengthens. It brings about various effects such as realization of space saving related to the arrangement of shaku members.

Further, the adapter AD may be integrated with the connector CN, the branch protection member BM, or the like. In this case, the connector CN with the adapter AD integrated, the branch protection member BM, or the like is directly attached to the binding band fixture WF. The branch portion protection member BM shown in FIG. 3B is an example of the branch portion protection member BM in which the adapter AD is integrated.

Further, the adapter AD is configured so that the binding band fixing tool WF can be separated from the binding band fixing tool WF in a state where the binding band fixing tool WF is fitted into the screw hole of the nut NT. Therefore, the operator can easily remove the adapter AD from the cable tie fixture WF without removing the cable tie fixture WF from the nut NT.

The fitting portion JP may be formed in the connecting portion CP, for example, as shown in FIGS. 4 to 8. Then, the connecting portion CP may have an insertion portion IP into which the binding band TB is inserted.

With this configuration, as shown in FIG. 3C, for example, the operator attaches the connector CN to the fitting portion JP of the binding band fixture WF and inserts the binding band TB into the insertion portion IP to connect the connector. The wire harness WH extending from the CN can be folded back and bundled.

The fitting portion JP may be formed on the side surface of the connecting portion CP, for example, as shown in FIGS. 4, 7, and 8.

Alternatively, as shown in FIGS. 5 and 6, the fitting portion JP may be formed on the upper surface (+ Z side surface) of the connecting portion CP. Specifically, the adapter AD is formed with a pair of snap-fit portions SF (see FIG. 5 (C)) or a pair of snap-fit portions SFc (see FIG. 6 (C)) as a pair of protrusions. You may. Further, as shown in FIGS. 5 (C) and 6 (C), an opening TA may be formed in the fitting portion JP. Then, the opening TA and the pair of snap-fit portions SF or the pair of snap-fit portions SFc may be configured to engage with each other. In the examples shown in FIGS. 4 to 6, the adapter AD is configured to have the holding portion HK, but may have a different shape so as to correspond to another fixed object. good. In this case, the operator can attach another object to be fixed to the cable tie fixture WF simply by replacing the adapter AD.

Further, the upper surface TS of the connecting portion CP may be a flat surface as shown in FIG. In this configuration, for example, when the long member is arranged so as to be in contact with the upper surface TS and the long member is bound by the binding band TB inserted through the insertion portion IP, the long member and the upper surface TS are combined. It is possible to prevent the surface of the long member from being damaged by the friction between them. In this configuration, the contact area between the long member and the upper surface TS is made larger than that in the case where the upper surface TS is not a flat surface, such as when a through hole, a convex portion, or a concave portion is formed in the upper surface TS. This is because the contact surface pressure can be reduced.

The connecting portion CP may be made of a material softer than the material constituting the retaining portion RP. For example, in the example shown in FIG. 7, the portion constituting the upper surface TS of the connecting portion CP may be made of a material (for example, elastomer) softer than the material (for example, 66 nylon) constituting the other portion of the connecting portion CP. good. This configuration has the effect of more reliably preventing damage to the surface of the long member that comes into contact with the top surface TS.

A predetermined portion of the base BP may be made of a softer material than the other parts of the base BP. For example, as shown in FIG. 8, the sealing portion SL on the lower surface of the base BP may be made of a material (for example, an elastomer) that is softer than the material (for example, 66 nylon) constituting the other portion of the base BP. In this configuration, the sealing portion SL has the effect of being able to seal between the lower surface of the base portion BP and the end surface of the nut NT.

The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiments. Various modifications or substitutions can be applied to the above-described embodiments without departing from the scope of the present invention. In addition, each of the features described with reference to the above-described embodiments may be appropriately combined as long as there is no technical contradiction.

For example, in the above-described embodiment, the cable tie fixture WF is used when fixing the cable tie TB that bundles a plurality of long members in the house frame on the swivel frame to a structural member such as the swivel frame. .. However, the cable tie fixture WF bundles a plurality of long members such as hydraulic oil hoses, grease hoses, and electric cables on the surface of a drilling attachment composed of, for example, a boom 4, an arm 5, and a bucket 6. It may be used when fixing the binding band TB to structural members such as the boom 4, the arm 5, and the bucket 6.

Further, in the above-described embodiment, the insertion portion IP constitutes a part of the connecting portion CP, but may be omitted. That is, the connecting portion CP may be configured to have only the fitting portion JP.

Further, the adapter ADb shown in FIG. 5C has a cantilever type snap-fit portion SF, but has other types of snap-fit portions such as an annular type, a twist type, and a compression type. It may have a fitting structure other than the snap-fit portion.

Further, in the examples shown in FIGS. 4 to 6, the holding portion HK of the adapter AD includes the entry prevention portion ST, but the entry prevention portion ST may be omitted. FIG. 9 shows the adapter ADd, which is still another configuration example of the adapter AD. The adapter ADd is different from the adapter ADa shown in FIG. 4 (C) in that the intrusion prevention unit ST is omitted, but is the same as the adapter ADa in other respects. In the example shown in FIG. 9, the operator can fit the protruding guide portion of the connector CN into the holding portion HK from the + X side, and fit the protruding guide portion of the connector CN into the holding portion HK from the −X side. be able to.

Further, in the example shown in FIG. 4, the adapter ADa has a first claw portion RC1 provided on the + X side edge portion of the upper surface UF and a second claw portion RC2 provided on the −X side edge portion of the upper surface UF. It has a claw portion RC including and. Then, the claw portion RC, in cooperation with the raised portion in the connector CN, constitutes a fall-off prevention structure for preventing the connector CN from coming off from the adapter ADa.

However, as shown in FIG. 10, the fall-out prevention structure is composed of a combination of a claw portion RC (claw portion RCA) formed on the adapter AD and a connector side claw portion (not shown) formed on the connector CN. It may have been done. Specifically, as shown in FIG. 10, the falling-out prevention structure includes a claw portion RCA provided at the center of the upper surface UF of the adapter ADe and a protruding guide portion having a prismatic shape with an inverted trapezoidal cross section in the connector CN (FIG. It may be configured in combination with a connector-side claw portion provided in the center portion of the lower surface of (not shown).

Specifically, the claw portion RCA has a substantially wedge shape so that the height on the −X side (the height of the ridge from the upper surface UF) is higher than the height on the + X side, that is, gradually increases in the −X direction. It is formed so as to be. On the other hand, the connector-side claw portion has a substantially wedge shape so that the height on the −X side (the height of the ridge from the lower surface) is lower than the height on the + X side, that is, the height gradually decreases in the −X direction. It is formed like this. The operator can fix the connector CN and the adapter ADe to each other by engaging the protruding guide portion of the connector CN and the holding portion HK of the adapter ADe and abutting the claw portion RCA and the connector side claw portion. can.

Further, the combination of the claw portion RCA and the connector side claw portion can also function as an intrusion prevention portion. The intrusion prevention portion has a function of preventing the protruding guide portion of the connector CN from entering the holding portion HK from the −X side. That is, in the example shown in FIG. 10, the operator can fit the protruding guide portion of the connector CN into the holding portion HK from the + X side, but fit the protruding guide portion into the holding portion HK from the −X side. I can't. In this way, the entry prevention unit can limit the entry direction of the connector CN in one direction.
