Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp for a harness which holds a middle portion of a harness such as a vehicle wiring and a washer hose when the harness is routed along a mounting panel. The present invention relates to a harness clamp capable of holding a single harness even when there are a plurality of harness clamps.

[0002]

2. Description of the Related Art Conventionally, for example, a vehicle is provided with a power supply from a battery to electric devices on the front, rear, left and right of the vehicle body, an electrical connection between the electric devices on the front, rear, left and right sides of the vehicle, or provided at the front of the vehicle body. It is well known that wiring and a harness such as a washer hose are routed at a relatively long distance, such as supplying a cleaning liquid in a washer tank to a wiper device behind the vehicle body.

[0003] As described above, since such various types of harnesses are routed for a relatively long distance, an intermediate portion of the harnesses is held by a harness clamp, and the harnesses are caused by vibrations during running of the vehicle. I do not play.

FIGS. 7 to 9 show an example of such a harness clamp 1 (see, for example, Japanese Utility Model Publication No. 58-41427). Is held by one harness clamp 1.

[0005] In the drawing, a harness clamp 1 has a contact portion 1a that contacts the upper surface of a flange portion F in which ends of a plurality of body panels 4, 5, and 6 serving as mounting panels overlap.
A locking piece 1c partly formed integrally with a base 1b opposed to the contact portion 1a and contacting the lower surface of the flange portion F;
First holding tongue piece 1 extending upward from contact portion 1a
d and a second holding tongue 1e extending upward from the outer wall of the first holding tongue 1d are integrally formed of resin.

The locking piece 1c has a thin portion 1f at its base, whereby the tip 1g is rotatable, and the tip 1g is brought into contact with the lower surface of the flange portion F to make contact. By clamping the flange portion F in cooperation with the portion 1a, the harness clamp 1 is held by the flange portion F.

[0007] The first holding tongue piece 1d is open upward,
The harness 2 is inserted from the opening. Similarly, the second holding tongue 1e is also opened upward, and the harness 3 is inserted through this opening.

[0008]

By the way, in the harness clamp 1 configured as described above, the holding to the flange F as the mounting panel is performed by the joint of the contact portion 1a and the locking piece 1c. Since holding is performed by clamping the flange portion F, the holding force on the flange portion F is weak and unstable.

Further, a thin portion 1f is formed at the base of the locking piece 1c in order to secure ease of mounting and vibration absorption of the harness clamp 1, but when the harness clamp 1 is mounted or when the harness 2 is mounted. Due to the load associated with the weight of, 3, the locking piece 1 c is easily bent from the thin portion 1 f, and once the locking piece 1 c is bent, it has a habit and loses its elasticity, and the holding force is further reduced. In some cases, it may fall off the flange F.

In addition, since the harness clamp 1 is mounted on the flange F having a relatively special panel structure in a vehicle body, its versatility is limited in that its installation position is limited. In addition, since the harnesses 2 and 3 are held at positions separated from the wall surface of the vehicle body panel 6 as a mounting panel, play easily occurs due to vehicle body vibration and the like, and the harnesses 2 and 3 hit the vehicle body panel 6 and generate abnormal noise. This causes a problem that an extra load is generated which causes the locking piece 1c to bend as described above.

The present invention has been made in view of the above circumstances, and can not only improve the holding force while maintaining the ease of mounting on a mounting panel, but also improve the versatility. Moreover, an object of the present invention is to provide a harness clamp capable of holding a harness at a position close to a mounting panel.

[0012]

In order to achieve the above object, according to the present invention, the present invention is directed to a plate-like base extending along a mounting panel and an engaging hole formed in the mounting panel. An engaging claw protruding from an upper back surface of the plate-shaped base and a lower portion of the plate-shaped base are provided so as to abut on the mounting panel and fix an intermediate portion of a harness routed along the mounting panel. From the surface near the center of the plate-like base so as to hold the middle part of the second harness, which is routed along the mounting panel in parallel with the harness, independently of the harness. And a holding tongue piece extending toward the main body.

According to a sixth aspect of the present invention, the plate-shaped base extends along the mounting panel and the upper surface of the plate-shaped base projects from the upper back surface of the base so as to engage with the engaging hole formed in the mounting panel. An engaging claw, a contact piece provided at a lower portion of the plate-shaped base so that a back side thereof comes into contact with the mounting panel, and a middle part of a plurality of harnesses routed along the mounting panel in an independent state. A plurality of holding tongue pieces extending upward from the central surface of the plate-shaped base so as to be individually held are provided.

[0014]
