The clamp 10A has a substantially frame shape, and a long body such as a wire harness 20 for automobiles (hereinafter referred to as the harness 20) is inserted into a housing space S inside the frame from an insertion opening E with a part of the frame shape open. is inserted and held.

Specifically, the clamp 10A is made of a strip-shaped resin having a predetermined thickness (wall thickness) and width in the depth direction (the depth direction in FIG. 1; hereinafter referred to as the depth width). A substantially rectangular frame body having a substantially M-shaped upper side is formed by the .

The clamp 10A is provided with a pair of arm portions 12 and 14 from which guide portions 13 and 15 that deform to form an insertion opening E extend from the tip, and a base portion 11 from which the arm portions 12 and 14 extend from both sides. , the arm portions 12 and 14 from which the guide portions 13 and 15 extend from the tip and the base portion 11 constitute a substantially rectangular frame having a substantially M-shaped upper side, and the harness 20 is held inside the frame shape. An accommodation space S is provided.

The second guide portion 13 is directed from the upper end of the second arm portion 12 outward in the lateral width direction (toward the upper left in FIG. 1(b)), folded back into a U shape, and downwardly inward in the lateral width direction (in FIG. 1(b)) lower right direction), the tip thereof is located inside the second arm portion 12 in the width direction (right side in FIG. 1(b)), and is formed in an inverted J shape when viewed from the front. Note that the width direction refers to the horizontal direction in FIG. 1(b).
In addition, a lower corner portion 121, which is a joint portion between the lower portion of the second arm portion 12 and the base portion 11, is formed in an arc shape.

The first arm portion 14 extends in a direction slightly inclined toward the accommodation space S with respect to the base portion 11 (upper left direction in FIG. 1(b)) and protrudes outward in the width direction (right side in FIG. 1(b)). The first guide portion 15 extends from the front end thereof.

The first guide portion 15 is folded back from the upper end of the first arm portion 14 and extends downward inward in the lateral width direction (lower left direction in FIG. 1(b)), and the tip thereof extends downward from the tip of the second guide portion 13 to the second arm. It extends to the part 12 side. At the tip of the first guide portion 15 extending to the side of the second arm portion 12 below the tip of the second guide portion 13, there is provided a convex locking claw 16 protruding in an orthogonal direction upward, which is the direction outside the frame. ing.
Further, a lower corner portion 141, which is a joint portion between the lower portion of the first arm portion 14 and the base portion 11, is formed in an arc shape.

As described above, the second guide portion 13 extending from the upper end of the second arm portion 12 and the first guide portion 15 extending from the upper end of the first arm portion 14 have approximately the same inclination angle with respect to the base portion 11. In addition, they are symmetrical with respect to the insertion direction of the harness 20 and the central axis orthogonal to the base portion 11 . As a result, the second guide portion 13 extending from the upper end of the second arm portion 12 and the first guide portion 15 extending from the upper end of the first arm portion 14 form a substantially V-shape in front view, and as a whole , constitutes a clamp 10A which is a substantially rectangular frame having a substantially M-shaped upper side.

In addition, the rigidity of the second guide portion 13 extending from the upper end of the second arm portion 12 to the outside in the width direction, to the outside in the width direction, to the inside and the bottom in the width direction is increased. Therefore, due to the deformability of the second guide portion 13 with respect to the second arm portion 12 , the upper end of the first arm portion 14 is folded back and extends downward in the width direction, and the tip of the first arm portion 14 extends below the tip of the second guide portion 13 at the second position.

In order to hold the harness 20 with the clamp 10A configured as described above, the arm portions 12 and 14 are deformed to form an insertion opening portion E between the second guide portion 13 and the first guide portion 15. The harness 20 is passed through the insertion opening E, and the harness 20 is accommodated in the accommodation space S.

Specifically, as shown in FIG. 2(a), the harness 20 is arranged above the clamp 10A. More specifically, the harness 20 is arranged between the second guide portion 13 and the first guide portion 15 which form a substantially V-shape when viewed from the front.

Then, by moving the harness 20 downward, as shown in FIG. The space between the portions 15 is widened in the width direction.

As shown in FIG. 2(c), when the harness 20 is further moved downward, the second guide portion 13, which is less likely to deform with respect to the second arm portion 12, bends outward in the width direction. The first guide portion 15, which moves outward in the width direction and is more likely to be deformed relative to the first arm portion 14 than the deformability of the second guide portion 13, has a narrower bending angle with respect to the first arm portion 14. The first arm portion 14 curves outward in the width direction and moves outward in the width direction.

Further, when the harness 20 moves upward to be detached, the harness 20 abuts against the first guide portion 15, which is easily deformed with respect to the first arm portion 14, and moves upward with the upper end of the first arm portion 14 as a fulcrum. Since the guide portion 15 is deformed and the locking claw 16 provided at the tip of the first guide portion 15 is locked to the tip of the second guide portion 13 (see FIG. 3(b)), the harness 20 is inadvertently detached. can be prevented.

In order to detach the harness 20 from the clamp 10A capable of preventing the harness 20 from being unintentionally detached, the harness 20 is moved upward to the tip of the second guide portion 13 as shown in FIG. 3(b). When the harness 20 is further moved upward from the state in which the locking claw 16 is locked, the first guide portion 15 is opened together with the second guide portion 13 while the locking claw 16 is locked to the tip of the second guide portion 13 . Transform upward.

At this time, the second guide portion 13, which is difficult to deform with respect to the second arm portion 12, bends outward in the width direction of the second arm portion 12 and moves outward in the width direction (see FIG. 3(c)). Further, when the harness 20 is moved upward, the above deformation progresses, the locking of the locking claw 16 is released, and the harness 20 is inserted between the tip of the second guide portion 13 and the tip of the first guide portion 15. An opening E is formed so that the harness 20 can be separated from the clamp 10A.

Subsequently, a test to confirm the load required to insert the harness 20 into the clamp 10A configured in this way (hereinafter referred to as insertion load) and the load required to detach the harness 20 from the clamp 10A (hereinafter referred to as detachment load). will be described with reference to FIG.

In the confirmation test, a clamp in which the locking claw 16 was not formed at the tip of the first guide portion 15 was used as Comparative Example 1, and a U-shaped clamp as shown in FIG. 2 to compare the load. Also, in FIG. 4, pattern A shows the results of clamp 10A.

As shown in FIG. 4A, the insertion load of the harness 20 is almost the same at the beginning of insertion, but in the latter half of the insertion when the insertion load of Comparative Examples 1 and 2 decreases, the clamp 10A It was found that the insertion load did not decrease. From this, it was found that although the insertion load of the clamp 10A having the locking claw 16 did not decrease even in the latter half of the insertion, the load value itself did not become extremely large as compared with Comparative Examples 1 and 2.

On the other hand, as shown in FIG. 4(b), the detachment load of the harness 20 from the clamp 10A, as well as the detachment amount, compared to the comparative example 1 which does not have the locking claw 16 and the U-shaped comparative example 2 We found that it increased significantly.

Also, from the numerical values, it can be seen that although Comparative Examples 1 and 2 are released with a detachment load approximately equal to the insertion load, the clamp 10A does not detach unless a detachment load approximately 7 to 8 times the insertion load is applied. I found out.

As described above, this is because the locking claw 16 is locked to the tip of the second guide portion 13 when the harness 20 is detached. On the contrary, in comparative examples 1 and 2, in which the separating force is small, the harness 20 is likely to come off inadvertently.

As described above, the clamp 10A, which has a frame shape and holds the harness 20 inserted into the housing space S from the insertion opening E with a part of the frame shape open, is connected to the base portion 11 which constitutes a part of the frame shape. a first arm portion 14 extending from one end of the base portion 11; a second arm portion 12 extending from the other end of the base portion 11; A first guide portion 15 that is inclined toward the space S and guides insertion of the harness 20 into the accommodation space S; and a second guide portion 13 that guides the insertion of the harness 20 into the housing space S. The first guide portion 15 and the second guide portion 13 form an insertion opening E, The deformability of the guide portion 15 with respect to the first arm portion 14 is higher than the deformability of the second guide portion 13 with respect to the second arm portion 12, and the tip of the first guide portion 15 is located inside the frame from the tip of the second guide portion 13. An engaging claw 16 which is arranged at a certain lower position and engages the first guide portion 15 with respect to the second guide portion 13 in a direction from the inside of the frame to the outside of the frame (upward) to block the insertion opening portion E. is provided, the harness 20 can be reliably and easily held by the clamp 10A.

More specifically, the harness 20 can be securely held by inserting the harness 20 into the housing space S through an insertion opening E formed by deformation of the guide portions 13 and 15 extending from the arm portions 12 and 14 .

In addition, the first arm portion 14 having the first guide portion 15 extending from the tip thereof has an approximately V-shape in a front view that is convex outward in the lateral width direction, so that it is curved outward in the lateral width direction when the harness 20 is inserted. The insertion opening E can be easily formed by moving the first guide portion 15 outward in the width direction, and the insertion load of the harness 20 can be reduced.

In addition, since the insertion opening portion E is formed by the first guide portion 15 and the second guide portion 13, the harness 20 can be guided into the accommodation space S by the guide portions 13 and 15, and the harness 20 can be inserted into the accommodation space S. can be done.
Further, the deformability of the first guide portion 15 with respect to the first arm portion 14 is higher than the deformability of the second guide portion 13 with respect to the second arm portion 12, and the tip of the first guide portion 15 is the tip of the second guide portion 13. The locking claw 16 provided on the first guide portion 15 is engaged with the second guide portion 13 in the direction from the frame inner side to the frame outer side (upward). Thus, the insertion opening E can be closed, that is, the base portion 11, the arm portions 12 and 14, the guide portions 13 and 15, and the locking claw 16 can form a closed cross section. Therefore, even if an external force acts on the harness 20 inserted into the accommodation space S of the clamp 10A, the harness 20 can be prevented from being carelessly removed from the accommodation space S.

In addition, since the first guide portion 15 is provided with a locking claw 16 that locks the second guide portion 13 in a direction (upward) from the inside of the frame to the outside of the frame and closes the insertion opening portion E, Only by inserting the harness 20 along the guide portions 13 and 15 inclined toward the accommodation space S, the first guide portion 15 is deformed and the locking of the locking claw 16 to the second guide portion 13 is released. , the harness 20 can be inserted into the accommodation space S from the insertion opening E.

Further, when the harness 20 passes through the insertion opening E, the locking claw 16 engages the second guiding portion 13 in the direction (upward) from the inside of the frame to the outside of the frame due to the deformability of the first guiding portion 15, and is inserted. The mouth E can be closed.
In addition, since the locking claw 16 provided on the first guide portion 15 has a convex shape facing the outside of the frame and is locked to the tip of the second guide portion 13, the harness 20 inserted into the housing space S can be more easily pulled out. can be held securely.

More specifically, even if an external force is applied to the harness 20 inserted into the accommodation space S of the clamp 10A, the engaging claw 16 provided in the first guide portion 15 and having a convex shape directed toward the outside of the frame will Since the harness 20 is engaged with the tip of the second guide portion 13, it is possible to more reliably prevent the harness 20 from being carelessly detached from the housing space S.

In addition, since the inclination angles of the first guide portion 15 and the second guide portion 13 with respect to the base portion 11 are approximately the same and the directions are symmetrical with respect to the insertion direction of the harness 20, the harness 20 can be smoothly inserted into the accommodation space S. can be inserted.

More specifically, the inclination angles of the first guide portion 15 and the second guide portion 13 with respect to the base portion 11 are approximately the same, and are symmetrical with respect to the insertion direction of the harness 20 . The insertion force when inserting the harness 20 is applied to the first guide portion 15 and the second guide portion 13 which have the same inclination angle with respect to the base portion 11 and which are symmetrical with respect to the insertion direction of the harness 20. It can act substantially uniformly, and the harness 20 can be smoothly inserted into the accommodation space S.

The clamp 10</b>A configured in this manner can be provided on the protective cover 30 that protects the connecting portion between the post (not shown) of the battery 40 and the harness 20 .
Specifically, as shown in FIG. 5, the protective cover 30 includes a cover body 31 surrounding the posts of the battery 40, a flexible connecting portion 32 extending from a portion of the cover body 31, and a flexible It is composed of a clamp 10A provided at the tip of the connecting portion 32. As shown in FIG. In addition, although the protective cover 30 is all integrally made of resin, it may be constructed separately.

In the protective cover 30 constructed in this way, the cover main body 31 is attached to the + side post provided on the upper surface of the battery 40, and the terminal (not shown) provided at the end of the harness 20 is connected to the post. The harness 20 is held and attached by the clamp 10A.

Further, the cover body 31 can be attached to the harness 20 via the flexible connecting portion 32 connected to the clamp 10 that holds the harness 20, thereby preventing the cover body 31 from being lost during detachment.
Furthermore, the movement of the harness 20 can be restricted via the flexible connecting portion 32 in a state in which the connecting portion is covered with the cover body 31 . Therefore, the connecting portion can be stably covered with the cover main body 31 .

Next, a clamp 10B of an embodiment different from the clamp 10A will be described with reference to FIGS. 7 to 9. FIG.
In the description of the clamp 10B below, the configuration different from that of the clamp 10A will be described, and the same configurations will be given the same reference numerals, and detailed description thereof will be omitted.

FIG. 7 shows an explanatory diagram of the clamp 10B, FIG. 8 shows an explanatory diagram of an operation when inserting the harness 20 into the clamp 10B, and FIG. 9 shows an explanatory diagram of an operation when removing the harness 20 from the clamp 10B. .

Specifically, FIG. 7(a) shows a perspective view of the clamp 10B, and FIG. 7(b) shows a front view of the clamp 10B.
8(a) in FIGS. 8(a) and 8(b) are front views showing the state in which the harness 20 is arranged above the clamp 10B, and FIG. 8(c) shows a front view of the clamp 10B in a state where the harness 20 passes through the insertion opening E, and FIG. d) shows a front view of the clamp 10B with the harness 20 accommodated in the accommodation space S of the clamp 10B.

FIG. 9(a) in FIG. 9, which is an explanatory view of the operation when the harness 20 is detached from the clamp 10B, shows a front view of the clamp 10B with the harness 20 accommodated in the accommodation space S, and FIG. The harness 20 moves upward in the accommodation space S and shows a front view of the clamp 10B in the process of being detached from the clamp 10B, and FIG. there is

The clamp 10B has a lower height in the vertical direction than the clamp 10A, but has the same general configuration. The different configurations are described below.
The first arm portion 14 of the clamp 10A extends in a direction slightly inclined toward the accommodation space S with respect to the base portion 11, and is formed in a roughly V-shape convex outward in the lateral width direction when viewed from the front. The one-arm portion 14B has an approximately V-shape in a front view that is convex outward in the width direction, but the lower half portion 14Bb is configured to incline outward in the width direction (toward the upper right in FIG. 7(b)). .
As a result, the lower half portion 14Bb of the first arm portion 14B and the first guide portion 15B extending from the tip of the first arm portion 14B are oriented in the same inclined direction from the lower left to the upper right.

Further, while the thick portion 17B of the lower corner portion 121B is formed with a uniform thickness, as shown in the enlarged view of part a in FIG. It is formed thinner than the part.

In the clamp 10A, the second guide portion 13 is directed upward and outward in the lateral width direction from the upper end of the second arm portion 12, is folded back in a U shape, and extends downward and inward in the lateral width direction. The second guide portion 13B of the clamp 10B is formed by folding the upper end of the second arm portion 12B into a V shape. In addition, a rib 18 is provided to connect and reinforce the inner corner side of the second guide portion 13B and the second arm portion 12B formed by folding back in a V shape.

Although the second guide portion 13B formed in this manner has a length approximately equal to that of the second guide portion 13 of the clamp 10A described above, the second guide portion 13B extends from the upper end of the second arm portion 12 outward in the lateral width direction upward, and extends in a U direction. Unlike the second guide portion 13 that is folded back in a letter shape, the tip of the second guide portion 13B that is formed by folding the upper end of the second arm portion 12B in a V shape is positioned at the center of the base portion 11 in the width direction. will be located. Therefore, the first guide portion 15B is also formed longer than the first guide portion 15 of the clamp 10A.

In order to hold the harness 20 with the clamp 10B configured in this way, the arm portions 12B and 14B are deformed to form an insertion opening portion E between the second guide portion 13B and the first guide portion 15B. The harness 20 is passed through the insertion opening E, and the harness 20 is accommodated in the accommodation space S.

Specifically, as shown in FIG. 8A, the harness 20 is arranged above the clamp 10B. More specifically, the harness 20 is arranged between the second guide portion 13B and the first guide portion 15B, which are substantially V-shaped when viewed from the front.
Then, by moving the harness 20 downward, as shown in FIG. 8B, the harness 20 contacts the second guide portion 13B and the first guide portion 15B inclined downward toward the inner side in the width direction, and the guide portion 13B , 15B in the horizontal direction.

As shown in FIG. 8C, when the harness 20 is further moved downward, the second guide portion 13B, which is less likely to deform with respect to the second arm portion 12B, bends outward in the width direction. The first guide portion 15B, which moves outward in the width direction and is more likely to deform relative to the first arm portion 14B than the deformability of the second guide portion 13B, has a narrower bending angle with respect to the first arm portion 14B. The first arm portion 14B curves outward in the width direction and moves outward in the width direction. An insertion opening E is formed between the tip of the second guide part 13B and the tip of the first guide part 15B. The harness 20 is inserted into the housing space S inside the housing space S, and the harness 20 is held in the housing space S.

In this manner, the clamp 10B that accommodates and holds the harness 20 in the accommodation space S has a gap in the vertical direction between the tip of the second guide portion 13B and the tip of the first guide portion 15B, similar to the clamp 10A. not penetrated. Further, when the harness 20 moves upward to be detached, the harness 20 contacts the first guide portion 15B, and the first guide portion 15B is deformed upward with the upper end of the first arm portion 14B as a fulcrum. Since the locking claw 16 provided at the tip of the second guide portion 13B is locked to the tip of the second guide portion 13B (see FIG. 9(b)), the harness 20 can be prevented from being unintentionally detached.

In order to detach the harness 20 from the clamp 10B capable of preventing the harness 20 from being unintentionally detached, as shown in FIG. When the harness 20 is further moved upward from the state in which the locking claw 16 is locked, the first arm portion 14B and the first arm portion 14B, which are more easily deformed than the second arm portion 12B by the lower corner portion 141B in which the thick portion 17B is thin, and the first arm portion 14B and the first arm portion 14B The guide portion 15B is deformed while the locking claw 16 is locked to the tip of the second guide portion 13B.

At this time, the second guide portion 13B, which is difficult to deform with respect to the second arm portion 12B, bends outward in the width direction and moves outward in the width direction (see FIG. 9B). Further, when the harness 20 is moved upward, the deformation as described above progresses, the locking of the locking claw 16 is released, and the harness 20 is inserted between the tip of the second guide portion 13B and the tip of the first guide portion 15B. An opening E is formed so that the harness 20 can be separated from the clamp 10B.

Regarding the insertion load required to insert the harness 20 of the clamp 10B configured in this way and the detachment load required to detach the harness 20 from the clamp 10B, the above-described clamp 10A and the above-described U-shaped clamp (Fig. 4(c) )), the insertion load of the harness 20 did not change much, but the separation load of the harness 20 from the clamps 10A and 10B was several times greater than that of the U-shaped clamp.

As described above, this is because the locking claw 16 is locked to the tip of the second guide portion 13B when the harness 20 is detached. On the other hand, in Comparative Example 2 where the detachment force is small, the harness 20 is likely to be unintentionally detached.

The clamp 10B having a different configuration as described above also has the same effects as the clamp 10A, and also has the following effects.
Specifically, since the tip of the second guide portion 13B to which the locking claw 16 is locked is arranged at a position corresponding to the central position in the extending direction (horizontal direction) of the base portion 11, the housing space can be more easily accommodated. A harness 20 can be inserted into S.

More specifically, the locking claw 16 provided on the first guide portion 15B is locked to the tip of the second guide portion 13B arranged at a position corresponding to the central position in the extension direction (horizontal direction) of the base portion 11. Therefore, the insertion force when the harness 20 is inserted along the guide portions 13B and 15B inclined toward the accommodation space S can be efficiently applied to the locking claw 16 so as to release the locking. The harness 20 can be inserted into the accommodation space S more easily.

Moreover, since the rib 18 which suppresses the deformability with respect to the 2nd arm part 12B of the 2nd guide part 13B is provided, the harness 20 can be made difficult to remove|deviate from the accommodation space S. FIG.
More specifically, since the second guide portion 13B to which the locking claw 16 engages is restrained from being deformable with respect to the second arm portion 12B by the ribs 18, the first guide portion 15B with respect to the second guide portion 13B is prevented from deforming. It becomes difficult to release the lock, and it is possible to prevent the harness 20 from coming out of the housing space S and accidentally falling off.

Further, since the deformability of the first arm portion 14B with respect to the base portion 11 is higher than the deformability of the second arm portion 12B with respect to the base portion 11, the harness 20 can be inserted into the housing space S more easily.

More specifically, the insertion force when the harness 20 is inserted along the guide portions 13B and 15B inclined toward the housing space S causes the first arm portion 14B to be deformed more than the base portion 11 of the second arm portion 12B. Since the base portion 11 is deformed, the first guide portion 15B and the first arm portion 14B provided with the locking claw 16 are deformed, and the locking of the locking claw 16 locked to the second guide portion 13B is released. The harness 20 can be inserted into the housing space S more easily.

Further, since the lower corner portion 141B of the first arm portion 14B with respect to the base portion 11 is formed to be thinner than the other portion, the deformability of the first arm portion 14B with respect to the base portion 11 is increased, and the first arm portion 14B is inclined toward the accommodation space S. The first arm portion 14B, which is highly deformable with respect to the base portion 11, is deformed with respect to the base portion 11 by the insertion force when the harness 20 is inserted along the guide portions 13B and 15B. The first guide portion 15B and the first arm portion 14B are deformed, the locking of the locking claw 16 locked to the second guide portion 13B can be easily released, and the harness 20 can be more easily inserted into the housing space S. can be done.

Further, since the lower half portion 14Bb facing in the same direction as the inclination direction of the first guide portion 15B is provided on the base portion 11 side of the first arm portion 14B, the harness 20 can be inserted into the accommodation space S more easily. can be done.

Specifically, the insertion force when inserting the harness 20 acts on the first guide portion 15B, and the insertion force acting on the first guide portion 15B also acts on the first arm portion 14B. At this time, since the lower half portion 14Bb provided on the base portion 11 side of the first arm portion 14B is oriented in the same direction as the inclination direction of the first guide portion 15B, the first arm portion 14B is directed toward the outside of the frame. , the harness 20 can be easily released from the locking claw 16 locked to the second guide portion 13B, and the harness 20 can be inserted into the housing space S more easily.
Even if the clamp 10B, which has an effect equal to or greater than that of the clamp 10A, is provided on the protective cover 30 like the clamp 10A, the same effect can be obtained.

Next, a clamp 10C of an embodiment different from the above-described clamps 10A and 10B will be described with reference to FIGS. 10 to 12. FIG.
In the description of the clamp 10C below, the configuration different from that of the clamp 10A and the clamp 10B will be described, and the same configurations will be given the same reference numerals, and detailed description thereof will be omitted.

FIG. 10 shows an explanatory diagram of the clamp 10C, FIG. 11 shows an explanatory diagram of operation when inserting the harness 20 into the clamp 10C, and FIG. 12 shows an explanatory diagram of operation when removing the harness 20 from the clamp 10C. .

Specifically, FIG. 10(a) shows a perspective view of the clamp 10C, and FIG. 10(b) shows a front view of the clamp 10C.
11(a) in FIGS. 11(a) and 11(b) show a front view of a state in which the harness 20 is arranged above the clamp 10C, and FIG. 11(c) shows a front view of the clamp 10C in a state where the harness 20 passes through the insertion opening E, and FIG. d) shows a front view of the clamp 10C with the harness 20 accommodated in the accommodation space S of the clamp 10C.

FIG. 12(a) in FIG. 12, which is an operation explanatory diagram when the harness 20 is detached from the clamp 10C, shows a front view of the clamp 10C with the harness 20 accommodated in the accommodation space S, and FIG. The harness 20 moves upward in the accommodation space S, and the front view of the clamp 10C in the middle of detaching from the clamp 10C is shown. FIG. , and FIG. 12D shows a front view of the clamp 10C with the harness 20 detached from the clamp 10C.

The clamp 10C has a height lower than that of the clamp 10A in the vertical direction, and is approximately the same height as that of the clamp 10B. The configuration different from the clamps 10A and 10B will be described below.

The first arm portion 14 of the clamp 10A extends in a direction slightly inclined toward the accommodation space S with respect to the base portion 11, and is formed in an approximately V-shape convex outward in the lateral width direction when viewed from the front. Like the first arm portion 14B of the clamp 10B, the first arm portion 14C has a substantially V-shaped configuration projecting outward in the lateral width direction when viewed from the front, but the lower half portion 14Cb is configured to incline outward in the lateral width direction. ing.
As a result, the lower half portion 14Cb and the first guide portion 15C extending from the tip of the first arm portion 14C are oriented in the same direction of inclination from the lower left to the upper right.

In the clamp 10A, the second guide portion 13 is directed upward and outward in the lateral width direction from the upper end of the second arm portion 12, is folded back in a U shape, and extends downward and inward in the lateral width direction. The second guide portion 13C of the clamp 10C is formed by folding the upper end of the second arm portion 12C into a V shape. In addition, the second guide portion 13B of the clamp 10B has a rib 18 that connects and reinforces the inner corner side of the second guide portion 13B formed by folding back into a V shape and the second arm portion 12B. The second guide portion 13C of the clamp 10C has an upper corner portion 131 with the second arm portion 12C formed thicker than the other portions.

Although the second guide portion 13C formed in this manner has a length approximately equal to that of the second guide portion 13 of the clamp 10A described above, the second guide portion 13C extends from the upper end of the second arm portion 12 outward in the lateral width direction upward, and extends in the U direction. Unlike the second guide portion 13 that is folded back in a letter shape, the tip of the second guide portion 13C that is formed by folding the upper end of the second arm portion 12C in a V shape is positioned at a position corresponding to the center of the base portion 11 in the width direction. will be located. Therefore, the first guide portion 15C is also formed longer than the first guide portion 15 of the clamp 10A.

In order to hold the harness 20 with the clamp 10C configured in this way, the arm portions 12C and 14C are deformed to form an insertion opening portion E between the second guide portion 13C and the first guide portion 15C. The harness 20 is passed through the insertion opening E, and the harness 20 is accommodated in the accommodation space S.

Specifically, as shown in FIG. 11(a), the harness 20 is arranged above the clamp 10C. More specifically, the harness 20 is arranged between the second guide portion 13C and the first guide portion 15C, which are substantially V-shaped when viewed from the front.

By moving the harness 20 downward, as shown in FIG. The portion 14C and the first guide portion 15C are entirely deformed to widen the space between the second guide portion 13C and the first guide portion 15C in the width direction.

As shown in FIG. 11(c), when the harness 20 is further moved downward, the second guide portion 13C, which is less likely to deform with respect to the second arm portion 12C, bends outward in the width direction. The first guide portion 15C, which moves outward in the width direction and is more likely to deform relative to the first arm portion 14C than the deformability of the second guide portion 13C, has a narrower bending angle with respect to the first arm portion 14C. The first arm portion 14C curves outward in the width direction and moves outward in the width direction. An insertion opening E is formed between the tip of the second guide part 13C and the tip of the first guide part 15C. The harness 20 is inserted into the housing space S inside the housing space S, and the harness 20 is held in the housing space S.

Thus, the clamp 10C that accommodates and holds the harness 20 in the accommodation space S does not penetrate in the vertical direction like the clamp 10B. 15C, the first guide portion 15C is deformed upward, and the locking claw 16 of the first guide portion 15C is locked to the tip of the second guide portion 13C (see FIG. 12(C)). Unintentional detachment of the harness 20 can be prevented.

In order to detach the harness 20 from the clamp 10C capable of preventing the harness 20 from being unintentionally detached, the harness 20 is moved upward to the tip of the second guide portion 13C as shown in FIG. 12(b). When the harness 20 is further moved upward from the state in which the locking claw 16 is locked, the first guide portion 15C is opened together with the second guide portion 13C while the locking claw 16 is locked to the tip of the second guide portion 13C. transform.

At this time, the second guide portion 13C, which is difficult to deform with respect to the second arm portion 12C, bends and deforms outward in the width direction, and moves outward in the width direction (see FIG. 12(c)). Further, when the harness 20 is moved upward, the deformation as described above progresses, the locking of the locking claw 16 is released, and the harness 20 is inserted between the tip of the second guide portion 13C and the tip of the first guide portion 15C. An opening E is formed so that the harness 20 can be separated from the clamp 10C.

Regarding the insertion load required for inserting the harness 20 of the clamp 10C configured in this way and the detachment load required for detachment of the harness 20 from the clamp 10C, the above-described clamp 10A and the above-described U-shaped clamp (Fig. 4(c) )), the insertion load of the harness 20 did not change much, but the separation load of the harness 20 from the clamps 10A and 10C was found to be several times greater than that of the U-shaped clamp.

As described above, this is because the locking claw 16 is locked to the tip of the second guide portion 13 when the harness 20 is detached. On the other hand, in Comparative Example 2 where the detachment force is small, the harness 20 is likely to be unintentionally detached. In addition, it has been confirmed that the clamp 10C having a different configuration as described above has the same effect as the clamp 10A.
Therefore, even if the clamp 10C is provided on the protective cover 30 like the clamp 10A, the same effect can be obtained.
