Description

  The present invention relates to a belt clamp for attaching a secondary cable such as another wire harness or a hose to a main cable such as a wire harness.

Some belt clamps of this type have a configuration in which a C-shaped holder portion is integrally resin-molded on the side portion of the buckle portion. After this belt clamp is attached to the outer periphery of a main cable such as a wire harness, a cable (another wire harness, single wire, hose, etc.) is attached according to a C-shaped holder. As a result, the slave cable is added to the main cable.
In addition, as a general technique regarding a belt clamp, it is disclosed by patent document 1, for example.
JP2003-028111

  In the conventional belt clamp, the position of the auxiliary cable is determined depending on the position of the buckle portion (C-shaped holder portion) in a state where the belt clamp is attached to the main cable. For this reason, the side-by-side position of the sub cable may change due to a difference in the diameter of the main cable. Further, since the slave cable is clamped by the C-shaped holder portion, the difference in the diameter of the slave cable cannot be absorbed, and the slave cable is easily detached from the holder portion.

  The present invention is intended to solve such a problem, and its purpose is to allow the cable to be provided in a stable state in accordance with an arbitrary position on the outer periphery of the main cable. It is to be able to attach the belt part firmly.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 is a belt clamp in which a sub-clamp attached to the outer periphery of the sub cable is coupled to a belt portion of the main clamp attached to the outer periphery of the main cable, so that the cable can be provided along with the main cable. A lock member that is slidably attached in the length direction to the belt portion of the main clamp and that can be coupled to a holding portion provided in the sub clamp, and the lock member, And a lock claw provided to be able to engage with an existing tooth row of the belt portion of the main clamp.

  According to this configuration, the lock member is slid along the belt portion of the main clamp, and the lock claw is engaged with the tooth row at an arbitrary position, thereby locking the lock member to the belt portion of the main clamp at that position. be able to. Therefore, by attaching the main clamp to the outer periphery of the main cable and connecting the holding portion of the sub clamp attached to the outer periphery of the sub cable to the lock member, regardless of the difference in the diameter of the main cable, The cable can be installed in a stable state according to the position. Moreover, since the subclamp belt portion is tightened on the outer periphery of the sub cable, the sub cables are firmly attached to each other.

  The invention according to claim 2 is the belt clamp according to claim 1, wherein the lock member includes a seat portion provided with a belt insertion portion for allowing the belt portion of the main clamp to be inserted. A coupling portion that is coupled to the holding portion of the sub-clamp is located substantially at the center on one side of the seat portion, and a lock claw is located almost at the center on the opposite side.

  As a result, in a state where the cable is provided along with the main cable, the lock claw is unlikely to be disengaged from the tooth row of the belt portion of the main clamp, and as a result, the lock member is locked to the belt portion of the main clamp.

  According to a third aspect of the present invention, in the belt clamp according to the second aspect, the lock claw of the lock member is provided on a lever portion formed so as to be elastically operable with respect to the seat portion. By operating the lever portion, the lock claw can be disengaged from the tooth row of the belt portion of the main clamp.

  In this case, the lock member can be unlocked with respect to the belt portion of the main clamp by operating the lever portion, and the lock member can be smoothly slid along the belt portion of the main clamp in this state.

  The invention according to claim 4 is the belt clamp according to claim 3, wherein the lever portion of the lock member is prevented from being unlocked by the holding portion of the sub clamp coupled to the coupling portion. Is set to

  Thereby, in the state where the cable is provided along with the main cable, the lock of the lock member with respect to the belt portion of the main clamp is held, and the sub cable is prevented from moving in the circumferential direction of the main cable.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a state in which two types of clamps are combined. As shown in this drawing, the belt clamp of the present invention can be used in combination with a main clamp 10 and a sub clamp 20. When the structure of both the clamps 10 and 20 is roughly divided, the buckle parts 12 and 22 and the belt parts 16 and 26 are provided individually. The clamps 10 and 20 are integrally molded products made of a synthetic resin material, and the base end portions of the belt portions 16 and 26 having a predetermined length are coupled to one side portions of the buckle portions 12 and 22, respectively. Yes.

  The buckle portion 12 of the main clamp 10 includes a belt insertion portion 12a penetrating in the vertical direction in FIG. The belt portion 16 can be inserted into the belt insertion portion 12a from the lower side of FIG. Further, the buckle portion 12 includes a locking leg 14 and a stabilizer 15 on the side opposite to the portion where the belt portion 16 is coupled. On the other hand, on one side surface of the belt portion 16, tooth rows 16a are formed at a constant pitch along the length direction thereof. Accordingly, the belt portion 16 is inserted into the belt insertion portion 12a of the buckle portion 12 and tightened, whereby an engagement claw (not shown) located in the belt insertion portion 12a is connected to some of the tooth rows 16a. (Two or more) engage. Thereby, the belt part 16 is locked to the buckle part 12 side in the tightening position.

  FIG. 2 is a plan view showing the sub clamp 20. FIG. 3 is an enlarged cross-sectional view in the direction of arrows AA in FIG. FIG. 4 is a left side view of FIG. The sub-clamp 20 shown in these drawings also includes a belt insertion portion 22a penetrating in the vertical direction in FIG. 3, and an engagement claw 22b is provided therein. Further, on one side surface of the belt portion 26, tooth rows 26a are formed at a constant pitch along the length direction thereof. When the belt portion 26 is inserted into the belt insertion portion 22a from the upper side of FIG. 3 and tightened, some of the tooth rows 26a are engaged with the engaging claws 22b, and the same as in the case of the main clamp 10. The belt portion 26 is locked to the buckle portion 22 side at the tightening position.

  The buckle portion 22 of the sub-clamp 20 includes a holding portion 24 on the opposite side of the portion where the belt portion 26 is coupled. The holding portion 24 has an insertion portion 24a penetrating in the vertical direction in FIG. 3 in substantially the same manner as the belt insertion portion 22a. A coupling portion 34 of the lock member 30 described below can be inserted into the insertion portion 24a, and the planar shape of the insertion portion 24a is an H shape corresponding to the coupling portion 34 of the lock member 30. (Fig. 2). Further, an engagement protrusion 24b is provided on the inner wall of the insertion portion 24a as shown in FIG. This engagement protrusion 24b is formed in the operation part 24c which is a part of wall which comprises the insertion part 24a. The operation portion 24c is partially separated from the wall of the insertion portion 24a on both sides thereof (FIG. 4). Thereby, the operation part 24c can be bent by the elasticity of the resin material in the outward direction of the holding part 24 (left direction in FIG. 3) together with the engaging protrusion 24b.

  FIG. 5 is a perspective view showing the lock member 30 together with a part of the main clamp 10. 6 is a plan view of the lock member 30, FIG. 7 is a front view of the lock member 30, and FIG. 8 is a cross-sectional view in the direction of arrows BB in FIG. As shown in these drawings, the configuration of the lock member 30 is roughly divided into a seat portion 32 and a coupling portion 34. The coupling part 34 is located in a fashionable manner rising from the upper surface of the seat part 32, and is constituted by a central wall 34a and side walls 34c on both sides thereof. The front end portions of the central wall 34a and the side walls 34c are inclined surfaces for facilitating the insertion of the coupling portion 34 into the insertion portion 24a of the holding portion 24 in the sub clamp 20 (FIGS. 5 and 8). The center wall 34a is provided with an engagement hole 34b that can be engaged with an engagement protrusion 24b provided on the inner wall of the insertion portion 24a. The central wall 34a is located substantially at the center on the upper surface side of the seat portion 32.

  The seat portion 32 of the lock member 30 includes a belt insertion portion 36 on the lower surface side. The belt portion 16 of the main clamp 10 can be inserted into the belt insertion portion 36 as shown in FIG. That is, the belt insertion portion 36 has a pair of support portions 36a that protrude from the lower surface of the seat portion 32 (FIG. 7). The tip ends of these support portions 36a are bent inward, and support the belt portion 16 from below.

  A lock claw 38 that can be engaged with the tooth row 16 a of the belt portion 16 is provided on the lower surface of the seat portion 32 in the belt insertion portion 36. The lock claw 38 is located at the approximate center of the lower surface side of the seat portion 32 (FIG. 8). The lock claw 38 is provided on a lever portion 37 that constitutes a part of the seat portion 32. The lever portion 37 is partially separated from the seat portion 32 on both sides thereof (FIG. 4). Thereby, the lever part 37 can be bent together with the lock claw 38 in the upward direction of FIGS.

Next, a procedure for coupling the main clamp 10 and the sub clamp 20 will be described.
First, in order to couple the main clamp 10 and the lock member 30, the belt portion 16 of the main clamp 10 is inserted into the belt insertion portion 36 of the lock member 30 with the tooth row 16a as an upper surface (FIG. 5). By inserting the belt portion 16 into the belt insertion portion 36, one of the tooth rows 16a engages with the lock claw 38 in the belt insertion portion 36, but by bending the lever portion 37 upward, the tooth row 16a The state where the engagement with the lock claw 38 is released can be maintained. Therefore, the lock member 30 can be slid to an arbitrary position along the belt portion 16. Then, by returning the lever portion 37 to the original state at an arbitrary position, the lock claw 38 is engaged with one of the tooth rows 16a, and the lock member 30 is locked to the belt portion 16 at that position.

  Next, the holding portion 24 of the sub clamp 20 and the coupling portion 34 of the lock member 30 are coupled. FIG. 9 is a cross-sectional view showing this coupling state. As shown in this drawing, the coupling portion 34 is inserted into the insertion portion 24a of the holding portion 24 from the upper side of FIG. By this insertion, the engagement protrusion 24b in the insertion portion 24a is engaged with the engagement hole 34b of the coupling portion 34. For this reason, the holding part 24 and the coupling part 34 are held in the retaining state, and the holding part 24 and the lock member 30 are coupled to each other. Further, the planar shape of the insertion portion 24a in the holding portion 24 is an H shape into which the central wall 34a and both side walls 34c of the coupling portion 34 are inserted, so that the coupling state of the holding portion 24 and the lock member 30 is stable. To do.

  In a state where the holding portion 24 of the sub clamp 20 and the lock member 30 are coupled, the end surface of the holding portion 24 is in contact with the seat portion 32 of the lock member 30. Therefore, the lever part 37 cannot be bent upward, the tooth row 16a and the lock claw 38 are held in the engaged state, and the sliding of the lock member 30 with respect to the belt part 16 is prevented. In order to change the position of the lock member 30, after removing the holding portion 24 from the lock member 30, the lever portion 37 of the lock member 30 is bent upward to engage the tooth row 16 a and the lock claw 38. (Lock) may be released. In order to remove the holding portion 24 from the lock member 30, the operation portion 24 c of the holding portion 24 is bent outward to disengage the engagement protrusion 24 b from the engagement hole 34 b of the coupling portion 34.

  FIG. 10 is an explanatory diagram showing a state in which a cable is provided along with the main cable. As shown in this drawing, the main clamp 10 has its belt portion 16 wound around the outer periphery of the wire harness 40 (main cable) in a loop shape, and this belt portion 16 is inserted into the belt insertion portion 12a of the buckle portion 12. Tighten. Thereby, as already demonstrated, the belt part 16 is locked to the buckle part 12 side in the tightening position. On the other hand, the belt portion 26 of the sub-clamp 20 is wound around the outer periphery of another wire harness 41 (secondary cable) in a loop shape, inserted into the belt insertion portion 22a of the buckle portion 22, and tightened. As a result, the belt portion 26 is locked to the buckle portion 22 side at the tightening position.

  Since the holding portion 24 of the sub clamp 20 is coupled to the belt portion 16 of the main clamp 10 through the lock member 30, as shown in FIG. 10, a wire harness 41 that is a cable following the wire harness 40 that is a main cable. Is attached. The locking leg 14 of the main clamp 10 is inserted into a mounting hole 51 formed in a plate 50 such as a vehicle body (FIG. 10), whereby both wire harnesses 40 and 41 are positioned with respect to the plate 50. The

  In addition, as an operation | movement procedure for attaching the wire harness 41 which is a cable according to the wire harness 40 which is a main cable, after attaching the main clamp 10 and the sub clamp 20 to the outer periphery of each wire harness 40 and 41, respectively. It is realistic to connect the clamps 10 and 20 of the two. That is, the main clamp 10 is attached to the outer periphery of the wire harness 40 in the state of FIG. 5 in which the belt portion 16 of the main clamp 10 is inserted into the belt insertion portion 36 of the lock member 30. At this time, as described above, the lever portion 37 of the lock member 30 is bent upward to disengage the tooth row 16a from the lock claw 38, thereby freely positioning the lock member 30 with respect to the belt portion 16. Can be adjusted. Finally, the holding portion 24 of the sub clamp 20 attached to the outer periphery of the wire harness 41 and the lock member 30 are coupled.

  As is apparent from the above description, the lock member 30 is slid with respect to the belt portion 16 of the main clamp 10 and the lock claw 38 of the lock member 30 is engaged with the existing tooth row 16a, so that the belt is in that position. The lock member 30 can be locked to the portion 16. Then, the sub clamp 20 can be coupled to an arbitrary position of the belt portion 16 by coupling the coupling portion 34 of the lock member 30 and the holding portion 24 of the sub clamp 20. Further, in a state where the holding portion 24 of the sub clamp 20 and the lock member 30 are coupled, the engagement (lock) of the lock claw 38 with the tooth row 16a cannot be released, and the tooth row 16a and the lock claw 38 are not connected. It is held in the engaged state. For this reason, in the state where both the wire harnesses 40 and 41 are provided, the shifting of the lock member 30 (that is, the sub clamp 20) with respect to the belt portion 16 is also eliminated.
