Description

  The present invention relates to a band clamp for a flat cable. Specifically, the band clamp is attached to a flat cable arranged in an automobile and fixed to a vehicle body panel.

Conventionally, a flat cable for wiring an automobile has a configuration in which a plurality of conductors or round electric wires made of copper foil are arranged at intervals, and both surfaces thereof are covered with a coating material made of a thin flexible resin sheet. It is used.
Since this type of flat cable has a relatively thin flat shape as a whole and has flexibility, the clamp for fixing the flat cable to the vehicle body panel has a pair of rigid holding members for holding the flat cable from both side surfaces. In many cases, a vehicle body locking portion projects from the outer surface of one of the clamping members. In the clamp, a pair of clamping members are opened and a flat cable is sandwiched between the clamping members.

  Further, in the clamp 100 shown in FIG. 8 proposed in Japanese Utility Model Laid-Open No. 5-73384 (Patent Document 1), a flat plate-like main body 101 and an upper lid portion 102 are formed. The elastic material 103 is protruded. The flat cable 104 is inserted between the main body 101 and the upper lid portion 102, and the flat cable 104 is pressed and held on the main body 101 side by the elastic material 103. In this state, the engagement provided on the main body 101 and the upper lid portion 102, respectively. The parts 101a and 102a are engaged.

  On the other hand, band clamps shown in FIG. 9 are often used in wire harnesses that are formed by concentrating covered round electric wires that have been widely used as wiring materials for wiring to automobiles. The band clamp 120 protrudes from the main body 122 with a band piece 121 provided with a continuous locking groove, and after the band piece 121 is wound around the wire harness 130, the band clamp 120 is locked with the locking groove of the band piece 121. The stopper piece is inserted into the insertion hole 123 provided so as to be fastened and locked.

  The band piece 121 of the band clamp 120 made of a resin molded product has higher rigidity than the flat cable, and the width of the main body 122 is smaller than the width of the flat cable. Therefore, as shown in FIG. 10, when the band clamp 120 is attached to the flat cable 140, a gap is generated between the band piece 121 wound around the arc shape and the holding force is weakened. In addition, since the flat cable 140 is wider than the main body 122, the flat cable 140 is easily bent when the band piece 121 is wound around the outer peripheral surface of the relatively thin flat cable 140. Furthermore, if the band piece 121 is tightly pulled and fastened after the band piece 121 is wound around the flat cable 140, there is a risk of damaging the covering material made of the resin sheet of the flat cable 140 and a conductor such as copper foil. Further, the band clamp 120 is likely to move laterally due to the movement of the flat cable 140 in the axial direction, and the band clamp 120 cannot be positioned and held. When the band clamp 120 is fixed to the vehicle body, the locking hole of the vehicle body panel and the band clamp 120 are positioned. There is a problem that tends to shift.

Japanese Utility Model Publication No. 5-73384

In the clamp having the pair of clamping members shown in FIG. 8 and the like, the clamping member needs to correspond to the width of the flat cable, and a pressing portion is necessary so that the flat cable cannot be moved to the clamping member. There is a problem that is complicated and expensive.
On the other hand, when the band clamp shown in FIG. 9 used for a wire harness made of a conventional round electric wire group is used for a flat cable, the above-described problem occurs.

  With respect to the above-described conventional thin and flexible flat cable, the applicant of the present application is Japanese Patent Application No. 2008-271823 and Japanese Patent Application No. 2008-310789 in which a plurality of strands 2 shown in FIGS. A flat cable 1 is provided in which flat conductors 4 in which aggregates 3 are brought into contact with each other in a parallel state are covered with an insulating resin coating layer 5 having a hardness as compared with a coating material made of a conventional resin sheet. FIG. 1A shows a case where one flat conductor 4 is provided, and FIG. 1B shows a case where a plurality of flat conductors 4 are covered with an insulating resin coating layer 5 in parallel.

  When a band clamp is attached to the flat cable 1, a gap is easily generated between the curved band piece and the flat cable 1 even if the flat cable 1 is fastened with a band piece having rigidity. In addition, the band piece easily slips in the axial direction with respect to the insulating resin coating layer 5 of the flat cable 1, and there is a problem that the band clamp cannot be positioned and held and attached to the flat cable 1.

  The present invention has been made in view of the above problems. The flat cable clamp is a band clamp, the flat cable is not bent, and the band clamp is positioned and held with respect to the flat cable without being laterally displaced in the axial direction. The task is to be installed.

In order to solve the above problems, the present invention is a band clamp that is attached to a flat cable in which a flat conductor is covered with an insulating resin coating layer,
A contact portion having a dimension corresponding to the width of the flat cable, a main body portion having a band through hole with a locking piece protruding from the inner surface,
A band piece protruding from the tip of the abutting portion of the main body,
It consists of a resin molded product having a vehicle body locking part protruding from the outer surface of the main body part,
The band piece is continuously provided with a locking groove for locking with the locking piece on one side surface of the width direction surface or the side surface of the thickness direction surface which is an outer peripheral surface when wound, and the inner side when the band piece is wound. A pressing protrusion is provided on the other surface in the width direction that is the peripheral surface,
There is provided a band clamp for a flat cable characterized in that when the band piece is wound around the flat cable, a surface facing the surface of the flat cable facing the contact portion is pressed by the pressing protrusion.

It is preferable that the pressing protrusions provided on the band piece have a triangular cross section and are provided in the length direction and in the width direction.
Thus, by providing a plurality of pressing protrusions in the length direction and the width direction, a uniform pressing force can be applied to the entire flat cable of the portion around which the band piece is wound, and the positioning holding force can be increased. .

Specifically, for example, in the first embodiment, the main body portion has a rectangular parallelepiped shape having a width corresponding to the width of the flat cable, and faces the vehicle body locking portion protruding from the upper surface of the main body portion. The lower surface is used as the contact portion, the band through hole penetrating in the width direction of the main body portion is provided, and the band piece projects from one end side of the band through hole.
In the band clamp, the abutting portion of the lower surface of the main body is brought into contact with the upper surface in the width direction of the flat cable, and the lower surface in the width direction of the flat cable around which the band piece is wound is pressed upward by the pressing protrusion of the band piece. The band clamp is positioned and held on the flat cable. The said vehicle body latching | locking part protrudes from the approximate center of the width direction of a flat cable.

In the second embodiment, a holding frame corresponding to the thickness of the band protrudes from the front end side (right end) opposite to the protruding side (for example, the left end) of the band piece, facing the band piece.
With this configuration, when the corner portion of the flat cable is abutted against the corner portion of the abutting portion of the lower surface of the main body portion and the holding frame, the upper surface in the width direction of the flat cable and one surface (left surface) in the thickness direction are the main body. The flat cable can be easily positioned with respect to the band clamp. Further, since the band piece to be wound is brought into contact with the front end surface of the holding frame and fastened, it is possible to prevent the flat cable from being excessively pressed by the pressing protrusion of the band piece.

  In a third form, the main body has an L shape in which the abutment portion protrudes in a right angle direction from one end of a base portion through which the vehicle body locking portion protrudes and penetrates the band through hole. The band piece protrudes from the tip, and the surface of the base that faces the vehicle body locking portion is a surface that contacts the thickness direction surface of the flat cable.

In the band clamp, when the corner of the flat cable is brought into contact with the corner of the base and the abutting portion, one surface in the thickness direction of the flat cable abuts the bottom surface of the base and the position surface in the width direction on the abutting portion. The flat cable can be easily positioned with respect to the band clamp.
Further, since the flat cable is sandwiched between the contact portion and the pressing protrusion of the band piece protruding from the corresponding contact portion, the band clamp can be positioned and held on the flat cable, as in the above-described embodiment.
In this embodiment, the vehicle body locking portion protrudes from the approximate center in the thickness direction of the flat cable.
That is, when the flat cable is attached to the first embodiment of the band clamp in a parallel arrangement, the flat cable is attached to the third embodiment of the band clamp in a vertical arrangement.

  In any of the first to third embodiments, since the entire one surface in the width direction of the flat cable is brought into contact with the contact portion of the main body, the flat cable is not bent when the band piece is wound around the other surface side. . In addition, since the pressing protrusion provided on the band piece is pressed against the surface facing the width direction surface of the flat cable abutted against the main body, the band clamp can be positioned and held on the flat cable. On the other hand, it is possible to reliably prevent lateral displacement.

  The vehicle body locking portion protruding from the main body portion of the band clamp according to the present invention has a pair of blade portions that protrude in a folded shape from the tip end of the shaft portion protruding from the main body portion, and is provided on the vehicle body panel at the front end of each blade portion. Further, a locking step portion that locks the periphery of the locking hole is provided.

In the flat cable to which the band clamp of the present invention is attached, the insulating resin coating layer covering the flat conductor is relatively hard. It is preferable to use the flat cable shown in FIG. 1 as the flat cable. The flat cable is formed as a single flat conductor by parallelly bringing together an assembly in which strands made of copper-based wire having a diameter of 0.95 to 0.60 mm are in contact with each other. The width direction dimension is about 10 to 100 mm, and the thickness dimension is about 30 to 50 mm. In the flat cable, a set of strands made of copper-based wire having a diameter of 0.95 to 0.60 mm is arranged in parallel so as to be in contact with each other to form one flat conductor. The insulating resin coating layer covering the flat conductor covers the conductor by extrusion molding.
Note that a plurality of the flat conductors may be arranged in parallel at intervals, and may be covered with the insulating resin coating layer, in which case the width of the flat cable becomes wide.

  Further, the flat cable to which the band clamp of the present invention is attached is not limited to the flat cable of FIG. 1, and a flat conductor is provided with a flat metal material, and the conductor is covered with an insulating resin coating layer having a hardness for extrusion molding. It is also suitably used for flat cables.

  The band clamp of the present invention may be attached to the flat cable on a one-to-one basis, or a plurality of flat cables may be laminated and the band piece of the band clamp of the present invention may be wound around the laminated body. Also in this case, since the other surface side of the band piece is pressed against the contact portion of the main body portion by the pressing protrusion provided on the band piece, the band clamp can be positioned and attached to the laminated flat cable.

  As described above, the band clamp for a flat cable of the present invention has a contact portion corresponding to the dimension of the flat surface in the width direction, and faces the contact portion in a state where the band piece is wound around the flat cable. The surface is pressed to the contact portion with a pressing protrusion protruding from the band piece. Therefore, the band clamp can be attached to the flat cable while being positioned and held, and the position of the band clamp can be prevented and the locking hole of the body panel and the body locking portion of the band clamp can be aligned. it can.

The band clamp 10 is made of a resin molded product, and as shown in FIGS. 2A to 2D, a rectangular parallelepiped main body 11, a band piece 12 projecting from the left end of the main body 11 in the figure, and a main body And a vehicle body locking portion 13 protruding from the upper surface of the portion 11.
The width A of the main body 11 is a dimension corresponding to the width W of the flat cable 1, and the abutting portion 15 for abutting the lower surface of the main body 11 on the flat cable 1 to the entire length of one surface of the upper surface 1 a in the width direction. It is said.

  The main body 11 is provided with a band through hole 16 in the width direction. In the figure, the left end is a band outlet 16b and the right end is a band inlet 16a. A locking piece 17 protrudes downward from the upper surface of the band through hole 16.

A band piece 12 having a relatively wide width is projected from the left end of the main body 11 where the band outlet 16b is provided. The band piece 12 is provided with a serrated locking groove 18 which is continuous along the length direction on the outer surface 12a which is an outer peripheral surface when the band piece 12 is wound around the flat cable 1.
On the other hand, a plurality of pressing protrusions 20 in the length direction X of the band piece 12 and in the orthogonal width direction B are formed on the inner surface 12b that is an inner peripheral surface that comes into contact with the flat cable 1 when the band piece 12 is wound around the flat cable 1. Is protruding.

  The pressing protrusion 20 has a plurality of lengths from a projecting point P1 from the main body 11 to a position P2 having a dimension corresponding to the thickness T of the flat cable 1 to a position P3 corresponding to the width W of the flat cable 1. (Three in this embodiment) are provided at intervals. In the width direction B, as shown in FIG. 2B, a plurality (two in this embodiment) are provided at intervals, and a total of six pressing protrusions 20 are provided. Each pressing protrusion 20 has a triangular cross-sectional state.

  The vehicle body locking portion 13 protruding from the upper surface of the main body portion 11 has a shaft portion 13a protruding from the main body portion 11 and is provided with wing portions 13b that are folded back from the tip of the shaft portion 13a to both sides. A locking step 13c is provided at the tip of 13b. Further, a dish portion 13d is provided around the base end of the shaft portion 13a so as to abut on a vehicle body panel (not shown).

  In the band clamp 10, the band piece 12 is fixed to the thickness of the flat cable 1 in a state where one surface (upper surface) 1 a of the flat cable 1 in the width direction is pressed against the contact portion 15 on the lower surface of the main body 11 of the band clamp 10. After winding from one surface 1b of the width direction surface to the lower surface 1c of the width direction surface and the other surface 1d of the thickness direction surface, the tip 12a of the band piece 12 is inserted into the band through hole 16 from the band inlet 16a of the main body portion 11. The band piece 12 pulled out from the outlet 16b is pulled, the locking piece 17 is locked in the locking groove 18 of the band piece 12, and the band clamp 10 is fixed to the flat cable 1 as shown in FIG.

Specifically, the vehicle body locking portion 13 of the band clamp 10 is held by a jig, and the flat cable 1 is abutted against the contact portion 15 on the lower surface of the main body portion 11 in this state. Next, the operator winds the band piece 12 around the flat cable 1 and passes it through the band through hole 16 to temporarily tighten it.
Next, the band piece 12 pulled out from the outlet 16b of the band through hole 16 is pulled by being sandwiched by a fastening jig and locked with the locking groove 18 and locked with a set fastening force. . Thereafter, the drawn band piece 12 is cut leaving a margin of 2-3 mm. It is visually confirmed whether the band clamp 10 is not laterally shifted after cutting.

  As described above, when the band clamp 10 is attached to the flat cable 1, the entire length in the width direction of the upper surface 1 a in the width direction of the flat cable 1 can be held in contact with the contact portion 15 of the main body 11, and the band piece 12 can be wound. Occasional bending of the flat cable 1 can be prevented. Further, the pressing protrusion 20 is pressed against the lower surface 1c of the flat cable 1 that contacts the abutting portion 15 and the flat cable 1 is pressed against the abutting portion 15 side with the required clamping force. Is clamped by the band clamp 10. Thus, the band piece 12 is not loosely wound around the upper and lower surfaces 1a and 1c in the width direction of the flat cable 1. Therefore, even if a gap is generated between the thickness direction surfaces 1 b and 1 d of the flat cable 1 and the band piece 12, the band clamp 10 does not move (laterally shift) with respect to the length direction of the flat cable 1. 10 can be positioned and held.

  Further, when the band clamp 10 is attached to the flat cable 1, the flat cable 1 is aligned with the band clamp 10 simply by abutting the abutting portion 15 of the band clamp 10 on the width direction surface 1a of the band attachment position of the flat cable 1. This makes it easy to attach the band clamp 10 to the flat cable 1.

FIG. 4 shows a band clamp 10-A of a modification of the first embodiment.
The band clamp 10-A is attached in a state where two flat cables 1A and 1B are laminated.
The difference from the band clamp 10 of the first embodiment is that the position of the pressing protrusion 20 provided on the band piece 12 is opened from the protruding point P1 from the main body 11 by the total thickness of the two flat cables 1A and 1B. Are different. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  In this way, even when two (or a plurality of two or more) flat cables are stacked, two sheets of the flat cable are disposed between the contact portion 15 of the band clamp 10-A and the pressing protrusion 20 of the band piece 12. Since the flat cables 1A and 1B can be clamped, the band clamp 10-A can be positioned and held without causing lateral displacement.

FIG. 5 shows a second embodiment of the band clamp.
The band clamp 10-B of the second embodiment has a holding frame 25 protruding from the lower surface of the main body 11 on the band inlet 16a side, which is different from the first embodiment.

Abutting on the contact portion 32, the thickness direction surface 1d abuts on the lower surface of the base 31, and can be easily aligned.
In this state, the band piece 12 is refracted upward from the thickness direction surface 1b serving as the lower end surface of the flat cable 1 and rotated to the back side of the width direction surface 1c, and then from the band inlet 16a of the base 31 to the band through hole 16. The locking piece 17 is locked in the locking groove 18 and fastened.
Since the flat cable 1 can be pressed toward the contact portion 32 by the pressing protrusion 20 of the band piece 12 in the fastening state of the band piece 12, the flat cable can be pressed and held between the contact portion 32 and the pressing protrusion 20. The band clamp 10 -C can be positioned and held with respect to the flat cable 1.

In the third embodiment, since the width A of the base 31 is larger than the thickness dimension T of the flat cable 1, as shown in FIG. 6C, attachment to a laminate of a plurality of flat cables 1 </ b> A and 1 </ b> B. Is particularly suitable.
That is, the thickness of the laminated body of the flat cable 1 is increased and can be made equal to the width A of the base portion 31, and no gap is generated between the wound band piece 12 and the flat cable 1. The band piece 12 can be attached in close contact.
