Description

The present invention relates to a clamp protector for protecting a cable clamp for attaching a cable such as a wire harness to a vehicle body, for example.

For example, a cable clamp is used as a jig for routing cables such as wire harnesses (hereinafter simply referred to as cables) in a vehicle. As disclosed in Patent Document 1, for example, this cable clamp is composed of a mounting body that is attached to a cable, and a clamp portion that attaches the mounting body to a vehicle body. Then, with the cable clamp attached to the cable using the attachment body, the cable can be routed in the vehicle by attaching the clamp portion to a predetermined position on the wiring route in the vehicle body.

Generally, the underfloor surface of the vehicle body (the surface that faces the ground during driving, etc.) is selected as part of the wiring route to the vehicle body. Therefore, the cable clamp attached to the cable routed under the floor is exposed to the ground. More specifically, the clamp part of a cable clamp generally includes an anchor that is inserted into a mounting point such as a mounting panel on the vehicle body, and a roughly dish-shaped part that contacts the vehicle body in a manner that covers the mounting point through which the anchor is inserted. and a biasing body. In the cable clamp configured in this way, the mounting body attached to the cable and the substantially dish-shaped biasing body in the clamp portion are exposed to the ground.

As a result, stones and other objects thrown up from the ground as the vehicle travels may collide with the cable clamp mounting body and approximately dish-shaped biasing body attached to the underfloor surface, resulting in so-called chipping. There was a risk of damage to the cable clamp.

As a measure to reduce the risk of damage to cable clamps due to such chipping, for example, the wiring route is set in a place under the floor of the vehicle body where the influence of chipping is less. The cable route becomes complicated. Along with this, there is a problem in that the length of the cable becomes longer and the weight of the cable (and thus the entire vehicle) increases.

Japanese Patent Application Publication No. 2002-142327

In view of the above problems, the present invention aims to provide a clamp protector that can reduce the risk of damage to the cable clamp due to chipping without complicating the cable routing route.

The present invention provides a clamp protector for protecting a cable clamp, which includes a mounting body attached to a cable and a clamp section for attaching the mounting body to a vehicle body, the mounting body protection section protecting the mounting body; A clamp protection part is provided in the clamp part and protects a biasing body formed in a substantially dish shape and biased by contacting the vehicle body , and the mounting body protection part includes a cable insertion opening through which the cable is inserted. and a plurality of deformable parts that are at least partially deformed when the cable having a diameter larger than a predetermined diameter is inserted.

According to the present invention, the cable clamp, more specifically, the mounting body and the substantially dish-shaped biasing body in the clamp portion, which are exposed to the ground when attached to the underfloor surface of a vehicle body, are protected. Ru. Thereby, the possibility of damage to the cable clamp due to chipping can be reduced without complicating the cable routing route.

Further, the diameter of the cable inserted into the cable insertion port of the attached body protection part varies depending on the connection destination (electronic equipment, battery, etc.), the specifications and destination of the vehicle body, and the like. On the other hand, it is conceivable to make the cable insertion opening large enough to allow the cables of various diameters to be inserted therethrough. However, in this case, when using the cable having a smaller diameter than the cable insertion opening, a gap is created between the cable and the cable insertion opening. This may cause the cable to move relative to the cable insertion port during installation work or after installation, which may impede the installation work of the clamp protection part and the protection of the cable clamp. There is a risk.

In contrast, the attached body protection part is provided with a plurality of deformable parts that deform when the cable having a diameter larger than a predetermined diameter is inserted, so that even if the diameter of the target cable is different, The deformable portion deforms according to the diameter and comes into contact with the cable. Thereby, relative movement of the cable with respect to the cable insertion port can be suppressed.

As an aspect of the present invention, the attached body protection portion may be a cross-sectional annular body through which the cable can be inserted.
According to the present invention, since the attached body can be surrounded by the attached body protection portion, it is possible to reduce the risk of damage to the attached body due to chipping.

Further, as an aspect of the present invention, a plurality of the deformable parts may be arranged in a circumferential direction on the inner surface of the attached body protection part which is an annular cross-sectional body.
According to this invention, the plurality of deformed portions come into contact with the cable along the circumferential direction, so that relative movement of the cable can be further suppressed.

Further, as an aspect of the present invention, the deformable portion may be arranged in an inclined posture in which the deformable portion is inclined toward the outside in the longitudinal direction of the cable in the attached body protection portion.
According to the present invention, when installing the clamp protector, the deformable portion reliably deforms to suppress relative movement of the cables having different diameters.

Specifically, when installing the clamp protector, if the deformable portion cannot be sufficiently deformed, there is a possibility that the cable having a large diameter cannot be inserted into the inside of the attached body protector. Further, even if the cable can be inserted, if a part of the deformed portion deforms inward in the axial direction or in the circumferential direction, the state of contact of the deformed portion with the cable becomes unstable.

On the other hand, since the deformable portion is inclined toward the outside in the longitudinal direction, the deformable portion easily and uniformly deforms outward in the longitudinal direction with respect to a large diameter cable. Thereby, the large-diameter cable can be reliably inserted into the inside of the attached body protection part, and a stable state of contact with the cable can be realized.

Further, as an aspect of the present invention, the attached body protection section may be provided with a cable fixing section that fixes to the cable in the attached state.
According to this invention, since the clamp protector can be fixed to the cable, the cable clamp can be protected more stably.

Further, as an aspect of the present invention, the clamp protection device and the attached body protection portion are provided with a clamp insertion port through which the clamp portion is inserted, and the clamp insertion port is provided along the longitudinal direction of the cable, One end in the longitudinal direction may be open.

According to this invention, the clamp protector can be installed in such a way that the clamp part is inserted through the open end of the clamp insertion opening, so the overall structure can be simplified and the installation work can be made easier. can.

Further, as an aspect of the present invention, the cable may be configured with a pair of divided components divided by a dividing plane along the cross section of the cable.
Furthermore, as an aspect of the present invention, the cable may be composed of a pair of split components separated by a split plane along a longitudinal section of the cable passing through the mounting body.

According to these inventions, the clamp protector can be installed in such a way that the band clamp is sandwiched between the pair of divided components, so the overall structure can be simplified and the installation work can be facilitated.

Further, as an aspect of the present invention, a connecting portion that connects the divided component parts may be provided.

According to this invention, since the divided components are connected to each other by the connecting portion, the cable clamp can be stably protected even if the clamp protector is configured as the divided component.

Further, as an embodiment of the present invention, it may be made of an elastomer.
According to the present invention, it is possible to absorb the impact of a stone or the like on the ground that is thrown up and hit as the vehicle travels, so that damage to the clamp protector can be suppressed. Therefore, the possibility of damage to the cable clamp protected by the clamp protector can be reduced.

According to the present invention, it is possible to provide a clamp protector that can reduce the risk of damage to the cable clamp due to chipping without complicating the cable routing route.

An embodiment of this invention will be described below with reference to the drawings.
First, the outline of the clamp protector 1 will be briefly explained based on FIG. 1. Here, FIG. 1 is a schematic explanatory diagram of the usage state of the clamp protector 1. Specifically, FIG. 1(a) shows the cable clamp 100 protected by the clamp protector 1 and attached to the vehicle body 300, and FIG. 1(b) shows the cable clamp 100 protected by the clamp protector 1. 100 is shown attached to a vehicle body 300.

The cable clamp 100 is a jig for fixing to the vehicle body 300 a cable 200 consisting of a wire harness whose one end is connected to electronic equipment, a battery, etc. (not shown), and is used to route the cable 200 to the vehicle. used for. Specifically, the cable clamp 100 includes a mounting body 110 that is attached to the cable 200 and a clamp section 120 that attaches the mounting body 110 to the vehicle body 300. Then, by attaching the cable 200 to the attachment body 110 and then attaching the clamp portion 120 to the vehicle body 300, the cable 200 can be fixed to the vehicle body 300.

As shown in FIG. 1(a), the attachment body 110 is configured as a lock band, and the band body 111 is fixed with a buckle 112 in a state in which a band body 111 is wound around the cable 200 and the cable 200 is tightened. This allows it to be attached to the cable 200.

The clamp portion 120 also includes an anchor 121 that is inserted into the attachment point 301 of the vehicle body 300, and a substantially dish-shaped biasing body 122 that contacts the vehicle body 300 in a manner that covers the attachment point 301 through which the anchor 121 is inserted. It consists of Note that by the urging body 122 coming into contact with the vehicle body 300, water or the like is prevented from entering the interior of the vehicle body 300 through the attachment location 301.

Here, the attachment point 301 of the vehicle body 300 is provided on the underfloor surface of the vehicle body 300 (the surface that faces the ground while driving, etc.), and the cable clamp 100 is attached to the underfloor surface of the vehicle body 300. Attached from the outside. Therefore, when the cable 200 is attached to the vehicle body 300 via the cable clamp 100, the attached body 110 and the biasing body 122 (strictly speaking, excluding the surface of the biasing body 122 facing the vehicle body 300) are attached to the cable clamp 100. The surface (hereinafter referred to simply as the exposed surface) is exposed to the ground. Therefore, there is a risk that the mounting body 110 and the exposed surface may be damaged by chipping. Therefore, the clamp protector 1 that protects the cable clamp 100 is used to reduce the possibility that the cable clamp 100 will be damaged by chipping.

The clamp protector 1 will be explained. The clamp protector 1 protects the cable clamp 100 and is made of an elastomer that has the strength necessary to protect the attachment body 110 and the biasing body 122 and has enough elasticity to allow deformation for attachment work. (resin material). As shown in FIGS. 1(a) and 1(b), the clamp protector 1 includes an attached body protector 10 that protects the attached body 110 and a clamp protector 20 that protects the biasing body 122. ing.

Specifically, the attached body protection unit 10 is configured to cover and protect the attached body 110 in the attached state in which the clamp protector 1 is attached to the cable clamp 100. Further, the clamp protection section 20 is configured to cover the exposed surface and protect the biasing body 122 in the attached state. That is, by attaching the clamp protector 1 to the cable clamp 100, the attached body 110 and the biasing body 122 are covered and protected by the attached body protection part 10 and the clamp protection part 20, and damage caused by chipping of the cable clamp 100 is protected. It can reduce the risk of

Further, the clamp protector 1 is composed of a pair of divided component parts 2, 2 divided by a dividing plane along the cross section of the cable 200. As shown in FIGS. 1(a) and 1(b), the divided components 2, 2 are configured symmetrically. Then, the clamp protector 1 can be attached to the cable clamp 100 by sandwiching the divided components 2, 2 from both sides of the cable 200 in the longitudinal direction X and bringing the divided surfaces into abutment. Thereby, the attached body protection part 10 and the clamp protection part 20 can protect the attached body 110 and the biasing body 122.

Furthermore, the clamp protector 1 (that is, each of the divided component parts 2, 2) is provided with a cable fixing part 30 fixed to the cable 200 in the attached state in the attached body protection part 10. Specifically, the cable fixing part 30 is configured in a plate shape extending from the attached body protection part 10 along the longitudinal direction X of the cable 200, and as shown in FIG. The cable fixing part 30 can be fixed to the cable 200 by wrapping the tape 40 together with the cable fixing part 200 .

That is, the clamp protector 1 is attached to the cable clamp 100 to which the cable 200 is attached, and the cable fixing part 30 is fixed to the cable 200. Subsequently, as shown in FIG. 1(b), the cable clamp 100 protected by the clamp protector 1 is attached to the vehicle body 300. Thereby, the possibility of damage to the cable clamp 100 due to chipping can be reduced.

Next, in order to clarify the structure of the clamp protector 1, the structure of each divided component 2 that constitutes the clamp protector 1 will be briefly described based on FIG. 2.

FIG. 2 shows an explanatory diagram of the divided component 2. As shown in FIG. Specifically, FIG. 2(a) shows a front view of the divided component 2, and FIG. 2(b) shows a side view of the divided component 2. ). FIG. 2(c) shows a plan view of the divided component 2 (view of the divided component 2 from above in FIG. 2(a)), and FIG. 2(d) shows the A- A sectional view is shown.

As shown in FIG. 2(a), the divided component 2 includes a mounting body protection section 10, a clamp protection section 20, and a cable fixing section 30. Furthermore, as shown in FIG. 2(b), FIG. 2(c), and FIG. 2(d), the attached body protection portion 10 is provided with a cable insertion port 11, a plurality of deformable portions 12, and a buckle receiving portion 13. It is being

Specifically, the cable insertion port 11 has an annular cross section through which the cable 200 can be inserted, and the cable 200 is inserted into the annular interior. A slit 11a is provided in the cable insertion port 11 along the longitudinal direction X when the cable 200 is inserted. Since the cable insertion port 11 is made of an elastically deformable resin material, the cable insertion port 11 can be expanded from the slit 11a to form a gap through which the cable 200 can pass. Thereby, the cable 200 can be inserted into the cable insertion port 11.

The deformable portion 12 deforms when a cable 200 having a diameter larger than a predetermined diameter is inserted. Specifically, the deformable portions 12 are configured as rod-shaped projections each having the same length extending radially inward from the inner surface of the cable insertion port 11, and are arranged in plurality in the circumferential direction. Note that the deformable portions 12 are arranged at equal intervals in the circumferential direction.

The deformed portion 12 does not extend to the center of the ring formed by the cable insertion port 11, but extends until an annular clearance S is formed in the center portion. Further, the deformable portion 12 is configured as an elastic biasing member, and when the cable 200 inserted into the cable insertion port 11 comes into contact with the deformable portion 12 and the deformable portion 12 deforms, a biasing force is applied to the cable 200. configured to work.

That is, when the cable 200 is inserted into the cable insertion port 11, the cable 200 comes into contact with a plurality of deformed parts 12 arranged in the circumferential direction in a manner surrounded by the deformed parts 12. A biasing force along the radial direction will act. Then, such biasing forces act on the cable 200 from various directions by the plurality of deformable portions 12, thereby suppressing the relative movement of the cable 200 with respect to the cable insertion opening 11.

Further, as shown in FIG. 2(d), each deformable portion 12 is disposed in an inclined attitude toward the outside in the longitudinal direction X of the cable 200 (rightward in FIG. 2(d)). By adopting such an inclined posture, the deformable portion 12 is easily deformed outward in the longitudinal direction can. Thereby, the direction of the urging force acting on the cable 200 can be stabilized, and the relative movement of the cable 200 can be stably suppressed by the deformable portion 12.

Furthermore, the deformed portions 12 are arranged such that when the pair of divided component parts 2 are butted against each other, the band body 111 is accommodated in the area formed between the respective deformed parts 12 in each of the divided component parts 2, 2. It is located. More specifically, it is provided at the outer edge of the cable 200 in the longitudinal direction X on the inner surface of the cable insertion port 11 . As a result, the band body 111 is housed within the region formed between the deformed portions 12 of the divided component parts 2, 2.

As shown in FIGS. 2(b) and 2(d), the buckle receiving portion 13 is a portion for receiving the buckle 112 in the mounting body 110, and is formed as a recessed portion capable of accommodating the buckle 112. When the clamp protector 1 is attached to the cable clamp 100, the buckle 112 is accommodated in the buckle receiving portion 13.

As shown in FIGS. 2(b), 2(c), and 2(d), the clamp protecting portion 20 is formed with a clamp receiving portion 21 that receives the clamp portion 120. This clamp receiving part 21 has a shape complementary to the biasing body 122, and is configured to be combined with the clamp receiving part 21 of the paired divided component 2 to cover the entire exposed surface. In addition, the surface of the clamp protection part 20 that faces the vehicle body 300 when attached to the cable clamp 100 faces the vehicle body 300 of the biasing body 122 when the clamp receiving part 21 receives the biasing body 122. It is formed so that it is flush with the surface to be covered.

Next, a method for attaching the clamp protector 1 configured as described above to the cable clamp 100 will be briefly described based on FIG. 3. Here, FIG. 3 shows an explanatory diagram of each stage of attaching the clamp protector 1 to the cable clamp 100.

First, as shown in FIG. 3(a), the divided component 2 is arranged so that the slit 11a faces the cable 200, and the cable insertion opening 11 is expanded from the slit 11a to allow the cable 200 to pass through. A gap A is formed. Next, as shown in FIG. 3(b), the cable 200 is placed in the cable insertion port 11 by passing through the gap A, and the expanded cable insertion port 11 is closed as shown in FIG. 3(c). Then, insert the cable 200 into the cable insertion port 11.

Then, the same operation is performed for the other divided component 2 as a pair, and the divided components 2 are arranged so as to sandwich the cable clamp 100 as shown in FIG. 3(d). Thereafter, as shown in FIG. 3(e), the pair of divided component parts 2 , 2 to sandwich the cable clamp 100. Finally, as shown in FIG. 3(f), each cable fixing part 30 is fixed to the cable 200 with tape 40.
In this way, the clamp protector 1 is attached to the cable clamp 100.

Furthermore, the state of the clamp protector 1 attached to the cable clamp 100 will be explained based on FIGS. 4 and 5.

Here, FIG. 4 shows an explanatory diagram of the clamp protector 1 attached to the cable clamp 100. Specifically, FIG. 4(a) shows the clamp protector 1 attached to the cable clamp 100 viewed from the longitudinal direction X, and FIG. 4(b) shows the line BB in FIG. 4(a). A cross-sectional view is shown. FIG. 5 shows a cross-sectional view of the attachment point 301 of the vehicle body 300 when the cable clamp 100 protected by the clamp protector 1 is attached to the vehicle body 300.

As shown in FIG. 4(a), the cable 200 inserted into the cable insertion port 11 is in a state of surrounding the circumferential direction of the cable 200, and the biasing force from each deformed portion 12 that is deformed by contacting the cable 200 is applied to the cable 200. Acts on 200. Thereby, the relative movement of the cable 200 is suppressed by the deformable portion 12.

As shown in FIG. 4B, a band body 111 is housed in the cable insertion opening 11 of the attached body protection part 10, and a buckle 112 is housed in the buckle receiving part 13. The biasing body 122 is accommodated in the clamp receiving portion 21 of the clamp protecting portion 20 .

In this way, the clamp protector 1 covers and protects the mounting body 110 and the biasing body 122 of the cable clamp 100 that are exposed to the ground. Further, the deformable portion 12 that contacts the cable 200 is deformed toward the outside in the longitudinal direction X of the cable 200.

Further, as shown in FIG. 5, the surface of the clamp protection portion 20 facing the vehicle body 300 is flush with the biasing body 122, and is in close contact with the vehicle body 300. This prevents water from entering the clamp receiving portion 21.

Next, the state of the clamp protector 1 when a cable 200a having a smaller diameter than that in FIG. 4 is used will be described based on FIG. 6. Here, FIG. 6(a) shows a view of the clamp protector 1 viewed from the longitudinal direction X, and FIG. 6(b) shows a sectional view taken along the line CC in FIG. 6(a).

When a cable 200a with a small diameter is used, as shown in FIGS. 6(a) and 6(b), the range of the deformable portion 12 that contacts and deforms the cable 200a becomes smaller, but the diameter of the cable 200a is reduced. A state in which directional biasing forces are applied from various directions by the plurality of deformed portions 12 is maintained. In this way, according to the clamp protector 1, even if the cables 200a have different diameters, the deformable portion 12 can suppress the relative movement of the cables 200a.

The clamp protector 1 configured in this manner protects the mounting body 110 and the biasing body 122 in the clamp portion 120, which are exposed to the ground when attached to the underfloor surface of the vehicle body 300. Therefore, the possibility of damage to the cable clamp 100 due to chipping can be reduced without complicating the routing route of the cable 200.

In addition, the clamp protector 1 is provided with a plurality of deformable parts 12 in the attached body protection part 10, which deform when the cable 200 having a diameter larger than a predetermined diameter is inserted. Therefore, even if the target cable 200 has a different diameter, the deformable portion 12 deforms in accordance with the diameter and comes into contact with the cable 200. Thereby, relative movement of the cable 200 with respect to the cable insertion port 11 can be suppressed.

Moreover, the plurality of deformable parts 12 are arranged in the circumferential direction on the inner surface of the attached body protection part 10 which is an annular cross-sectional body, and the plurality of deformable parts 12 come into contact with the cable 200 along the circumferential direction. Become. Thereby, relative movement of the cable 200 can be further suppressed.

Further, the deformable portion 12 is arranged in an inclined posture inclining toward the outside in the longitudinal direction of the cable 200 in the attached body protection portion 10, so that the deformable portion 12 is reliably deformed when the clamp protector 1 is installed. Therefore, relative movement of cables 200 having different diameters can be suppressed.

To explain in detail, when the deformable portion 12 cannot be sufficiently deformed when installing the clamp protector 1, there is a possibility that the large diameter cable 200 cannot be inserted into the inside of the attached body protector 10. Further, even if the cable 200 can be inserted, if a part of the deformable portion 12 deforms inward in the axial direction or in the circumferential direction, the state in which the deformable portion 12 contacts the cable 200 becomes unstable.

On the other hand, since the deformable portion 12 is inclined toward the outside in the longitudinal direction X, the deformable portion 12 can be easily and uniformly deformed outward in the longitudinal direction X relative to the cable 200 having a large diameter. Thereby, the large diameter cable 200 can be inserted into the inside of the attached body protection part 10 with high accuracy, and a stable contact state can be realized.

Moreover, since the attached body protection part 10 has an annular cross-section through which the cable 200 can be inserted, the attached body 110 can be surrounded by the attached body protection part 10, thereby reducing the risk of damage to the attached body 110 due to chipping. be able to.

Moreover, the attached body protection part 10 is equipped with a cable fixing part 30, and the clamp protector 1 can be fixed to the cable 200 by the cable fixing part 30, so that the cable clamp 100 can be protected more stably.

Further, the clamp protector 1 is composed of a pair of split components 2, 2 divided by a split plane along the cross section of the cable 200, and the cable clamp 100 is sandwiched between the pair of split components 2, 2. Clamp protector 1 can be installed with . Therefore, the overall structure can be simplified and installation work can be facilitated.

In addition, since the clamp protector 1 is made of elastomer, it can absorb the impact of stones on the ground that are thrown up and hit as the vehicle travels, so that the clamp protector 1 may be damaged. can be restrained from doing so. Therefore, the possibility of damage to the cable clamp protected by the clamp protector can be reduced.

This invention is not limited only to the configuration of the above-described embodiments, but can be implemented in many other embodiments.

For example, in the present embodiment, the clamp protector 1 is composed of a pair of divided components 2, 2, but a connecting portion may be provided to connect the divided components 2, 2 to each other.
An example of such another embodiment will be described using FIG. 7. FIG. 7 shows an explanatory diagram in which a connecting portion 50 is provided to the clamp protector 1 described above. Specifically, FIG. 7(a) shows a front view of the clamp protector 1 provided with the connecting part 50, FIG. 7(b) shows a DD cross-sectional view in FIG. 7(a), FIG. 7(c) shows a partially enlarged view of FIG. 7(b). Similarly, in another embodiment to be described later, the same reference numerals as in the above description are used, and configurations that are not particularly described are the same as in the above description.

As shown in FIGS. 7(a), 7(b), and 7(c), the connecting portion 50 includes a concave engaged portion 51 provided in one divided component 2A, and a concave engaged portion 51 provided in the other divided component 2A. It is comprised of a claw-shaped engaging portion 52 that engages with an engaged portion 51 provided at a corresponding location on the component 2B. As a result, the split components 2A and 2B are sandwiched from both sides of the cable 200 in the longitudinal direction 50 connects the divided component parts 2, 2 to each other.
With the clamp protector 1 configured in this way, the cable clamp 100 can be stably protected.

Further, in this embodiment, the divided components 2 are configured such that their divided surfaces are butted against each other, but this is not necessarily the case. Various configurations may be used in which the edges overlap.

An example of such another embodiment will be described using FIG. 8. FIG. 8 shows an explanatory diagram of the other embodiment. Specifically, FIG. 8(a) shows a front view of a clamp protector 1 of another embodiment, and FIG. 8(b) shows a sectional view taken along line EE in FIG. 8(a).

As shown in FIGS. 8(a) and 8(b), an edge of the attached body protection portion 10B of the other divided component 2B is placed on the outside of the edge 10A of the attached body protection portion 10 of one divided component 2A. The edges overlap. Thereby, gaps between the divided component parts 2, 2 can be further reduced.

Note that the structure is not limited to the one shown in FIG. 8, and the edges of the divided component parts 2, 2 may be shaped to be complementary to each other so that the edges fit into each other. Alternatively, the edge of one divided component 2 may be configured with the engaged portion 51, and the edge of the other divided component 2 may be configured with the engaging portion 52, so that they are engaged with each other.

Further, in the divided component parts 2, 2 in this embodiment, the pair of divided component parts 2, 2 may be connected to each other by a hinge or the like before being attached to the cable clamp 100. This prevents the pair of split component parts 2, 2 from coming apart, making the work easier.

Furthermore, in the present embodiment, the clamp protector 1 is composed of a pair of split components 2, 2 each having a split surface along the cross section of the cable 200, but the present invention is not necessarily limited to this. For example, the clamp protector 1 may be configured with a pair of divided components (upper divided component 3 and lower divided component 4) divided by a dividing plane along the longitudinal section of the cable 200 passing through the attachment body 110. However, the clamp protector 1 may also be composed of one component.

An example of another embodiment in which the clamp protector 1 is composed of an upper divided component 3 and a lower divided component 4 will be described using FIG. 9. FIG. 9 shows an explanatory diagram of this other embodiment, and specifically, FIG. 9(a) shows how the upper divided component 3 and the lower divided component 4 are attached to the cable clamp 100 to which the cable 200 is attached. A perspective view showing the previous state is shown. Further, FIG. 9(b) is a perspective view showing a state before the upper divided component 3 and the lower divided component 4 are attached to the cable clamp 100 to which the cable 200 is attached.

The upper divided component 3 is a component that is attached to the cable clamp 100 from above the cable 200 (the side facing the vehicle body 300), as shown in FIGS. 9(a) and 9(b). Further, the lower divided component 4 is a component that is attached to the cable clamp 100 from the lower side of the cable 200 (the side that does not face the vehicle body 300). That is, the upper divided component 3 protects the cable clamp 100 from above, and more specifically protects the upper half of the attached body 110 and the clamp part 120, and protects a part of the attached body protection part 10. and a clamp protection section 20. Further, the lower divided component 4 protects the cable clamp 100 from below and protects the lower half of the attachment body 110, and constitutes the remaining portion of the attachment body protection section 10.

The upper divided component 3 and the lower divided component 4 each have an arcuate shape when viewed from the side, and when both are attached to the cable clamp 100 and their divided surfaces are abutted against each other, the cable insertion port 11 will open. I am trying to configure it. Furthermore, the upper divided component 3 and the lower divided component 4 are each provided with a deformable portion 12 at a predetermined position on the inner surface thereof.

The clamp receiving part 21 formed in the upper divided component 3 has a shape corresponding to the shape of the urging body 122 in order to fit into the urging body 122, and the diameter becomes smaller from the upper side to the lower side. . Therefore, when the clamp part 120 is inserted into the clamp receiving part 21 of the upper divided component 3 from the anchor 121 side, the biasing body 122 cannot pass through the clamp receiving part 21 whose diameter becomes smaller toward the bottom. Can not. Therefore, the upper divided component 3 cannot be attached to the cable clamp 100.

Therefore, the upper divided component 3 is provided with a clamp insertion port 60 through which the clamp portion 120 is inserted, and the clamp insertion port 60 is provided along the longitudinal direction X of the cable 200 and on one side of the longitudinal direction The end (on the opposite side from the clamp receiving part 21) is open. Further, the other end of the clamp insertion port 60 communicates with the clamp receiving portion 21 .

Thereby, by inserting the clamp part 120 into one end, the clamp part 120 can be arranged up to the clamp receiving part 21. Specifically, the clamp insertion hole 60 is formed to have a width that allows at least the anchor 121 to be inserted therethrough, and the anchor 121 is inserted into the clamp insertion hole 60 and the clamp portion 120 is moved to the clamp receiving portion 21 . Thereafter, the upper divided component 3 can be attached to the cable clamp 100.

An example of a procedure for mounting the clamp protector 1 constituted by such an upper divided component 3 and a lower divided component 4 will be described. First, after attaching the upper divided component 3 to the cable clamp 100 by the method described above, the upper divided component 3 and the lower divided component 4 are sandwiched between the cable clamp 100 and the lower divided component 4 from below. Let the divided planes of be in contact with each other. Then, the upper divided component 3 and the lower divided component 4 are connected using a suitable connecting means (not shown) (having the same configuration as the connecting portion 50 described above, tape, etc.). In this way, the clamp protector 1 can be attached to the cable clamp 100.

Further, an example of another embodiment in which the clamp protector 1 is constructed from one component will be described using FIG. 10. FIG. 10 shows an explanatory diagram of this other embodiment, and specifically, FIG. 10(a) shows a perspective view showing a state before the clamp protector 1 of another embodiment is attached to the cable clamp 100. . Moreover, FIG.10(b) shows the perspective view which shows the state after equipping the cable clamp 100 with the clamp protector 1 of another embodiment. In addition, in this other embodiment, the same reference numerals as those in the above description are used, and the configurations that are not particularly described are the same as those in the above description.

As shown in FIGS. 10(a) and 10(b), the clamp protector 1 has a cylindrical shape with a C-shape in cross section. In addition, in the clamp protector 1, both sides of the cable 200 in the longitudinal direction X are open when the cable 200 is attached to the cable clamp 100, and the cable insertion opening 11 is formed by the openings on both sides in the longitudinal direction X and the internal area thereof. ing.

Inside this clamp protector 1, a plurality of deformed portions 12 as described above are formed at predetermined positions (not shown). Further, the clamp protector 1 is formed with a clamp receiving part 21 that receives the clamp part 120. That is, the portion of the clamp protector 1 that corresponds to the clamp receiving portion 21 constitutes the clamp protector 20, and the other portion constitutes the attached body protector 10.

The clamp receiving portion 21 is provided along the longitudinal direction X on both sides of the longitudinal direction Clamp insertion holes 60 are provided, each of which has its other end communicating with the clamp receiving portion 21 .

The clamp receiving portion 21 and the clamp insertion port 60 configured in this manner function as a slit in the longitudinal direction X in the clamp protector 1, and the entire clamp protector 1 can be expanded from there. Therefore, the cable clamp 100 and the cable 200 can be inserted through the expanded gap, and thereby the clamp protector 1 can be attached to the cable clamp 100.

Further, as a method of bringing the clamp portion 120 into the state where the clamp portion 120 is received in the clamp receiving portion 21, the following method may be mentioned. First, there is a method of opening the entire clamp protector 1, inserting the cable clamp 100 and the cable 200, and then closing the clamp protector 1 so that the clamp part 120 is received in the clamp receiving part 21.

Furthermore, as described above, after inserting the cable clamp 100 and the cable 200 inside the clamp protector 1, the anchor 121 is inserted into either of the clamp insertion holes 60 using the clamp insertion holes 60. , a method of moving the clamp part 120 to the clamp receiving part 21 and having the clamp receiving part 21 receive the biasing body 122, or a method of expanding one end and inserting the clamp part 120 to the clamp receiving part 21. One method is to do so.

In addition, in the above-mentioned other embodiment, it is not necessary to provide the clamp insertion hole 60, and instead of both or one of the clamp insertion holes 60 from the clamp receiving portion 21 to the openings on both sides in the longitudinal direction A slit may also be formed.

In the present embodiment, the clamp protector 1 is made of a resin material that has the strength necessary to protect the attachment body 110 and the biasing body 122 and has enough elasticity to allow deformation for attachment work. There is. The cable insertion port 11 is expanded from the slit 11a to form a gap through which the cable 200 can pass.

However, the clamp protector 1 is not necessarily limited to this configuration, and may be configured of other elastically deformable materials, for example. Another configuration is to use a material such as metal that cannot be elastically deformed, and use an expansion mechanism such as a hinge so that the cable insertion port 11 can be expanded from the slit 11a, so that the cable 200 can be passed through. Various configurations that can form a gap may be employed.

In this embodiment, a plurality of deformable parts 12 are arranged at equal intervals on the inner surface of the attached body protection part 10, and are arranged in an inclined attitude toward the outside in the longitudinal direction X of the cable 200. . The deformable portions 12 are configured as bar-shaped protrusions that extend radially inward and have the same length. However, the present invention is not necessarily limited to this, and any configuration may be used as long as it is deformed when the cable 200 is inserted.For example, various configurations may be adopted as described below.

For example, the deformable portions 12 may not be arranged at equal intervals in the circumferential direction, or a plurality of deformed portions 12 may be arranged along the longitudinal direction X. When the deformable portion 12 is disposed along the longitudinal direction They may be lined up. Thereby, biasing forces can be applied to the cable 200 from both the left and right sides.

For example, the deformable portion 12 does not have to be in the inclined position as described above, does not necessarily have to be inclined outward in the longitudinal direction X of the cable 200, and may be inclined inward. Alternatively, it may be inclined in the circumferential direction.

For example, the deformable portion 12 does not need to be a rod-shaped protrusion, and may have various shapes that deform when the cable 200 is inserted, such as a plate shape. Furthermore, the lengths do not all have to be the same; for example, the lengths may be longer from the upper side (the side of the vehicle body 300) to the lower side, or the lengths may be longer as they go to the lower side. The length may be shortened.

For example, FIG. 11 is an explanatory diagram of a state in which the length of the deformable portion 12 increases from the upper side to the lower side. In this case, as shown in FIG. 11, the annular clearance S drawn by the tip of the deformed portion 12 is closer to the upper side. 200 is easier to support from below, which is preferable.

Furthermore, if the length of the deformed portion 12 is made shorter from the top to the bottom, the clearance will be closer to the bottom, and the cable 200 will be placed in the lower part of the cable insertion port 11. This is preferable in such cases.

Furthermore, in the present embodiment, the clamp protection part 20 has a configuration in which the clamp receiving part 21 is formed in a shape complementary to the biasing body 122, and the exposed surface is covered by the clamp receiving part 21, but the structure is not necessarily limited to this. do not have. For example, any configuration may be used as long as the biasing body 122 can be housed inside and pebbles or the like can be prevented from entering the interior, such as simply receiving the biasing body 122 therein.

Furthermore, in the present embodiment, the surface of the clamp protection section 20 that faces the vehicle body 300 when attached to the cable clamp 100 (referred to as the "opposed surface") is biased when the clamp receiving section 21 receives the biasing body 122. It is configured to be flush with the surface of the rear body 122 facing the vehicle body 300. However, this is not necessarily the case; the opposing surface may protrude toward the vehicle body 300 from the surface of the biasing body 122 that faces the vehicle body 300, or may be set back from the surface of the biasing body 122 that faces the vehicle body 300. Good too.

Further, in this embodiment, the cable fixing part 30 has a plate-like configuration extending from the attached body protection part 10 along the longitudinal direction X of the cable 200, and by wrapping the cable fixing part 30 together with the cable 200 with the tape 40, The cable fixing part 30 is configured to be fixed to the cable 200. However, the present invention is not necessarily limited to this, and as long as the clamp protector 1 can be fixed to the cable 200, for example, a ring-shaped structure may be used, or the cable fixing part 30 itself may have a locking mechanism without using the tape 40. Any configuration may be used.

Further, in this embodiment, the attachment body 110 is configured as a lock band, but it is not necessarily limited to this. For example, various types of devices that can be attached to the cable 200 may be used, such as a tape-fixed type that is brought into contact with the cable 200 and is attached to the cable 200 by wrapping the cable 200 with tape.

The shapes and configurations of the clamp portion 120 and the attachment portion 301 for attaching the clamp portion 120 to the attachment portion 301 on the vehicle body 300 illustrated in the above description are merely examples, and one can be attached to the other. If so, various types may be used.

For example, in the above description, the cable 200 is configured as a wire harness, but it does not necessarily have to be a wire harness, and various materials such as optical fibers may be used.
Note that the other embodiments described above may be combined as appropriate.
