Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clamp for fixing a wire in an automobile, and more particularly, to a clamp for fixing a wire that can be easily bundled with a strap by forming a belt-shaped strap having a toothed inner surface integrally with the clamp.

Conventional wire fastening clips are tapered with multiple layers of black tape, which are poor in appearance and may cause inadvertent taping because multiple clips are attached to one wire at regular intervals. Torsion also occurs in the test wiring, and a crack is often generated around the mounting hole of the clip.

According to the present invention, the wiring contact portion has a curved surface at the bottom and a strap of a certain length can be bundled to secure the wires, and a torsion-preventing rib is formed up and down on the side surface, so that an empty space is formed between the ribs to twist the wiring. It is an object of the present invention to provide a clamp for fixing wires that can reduce the load when a load occurs.

Clamps for electrical wiring of automobiles

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp for electric wiring of a motor vehicle. In particular, the belt-shaped strap having a tooth length of a certain length is formed integrally with the clamp to bundle the wiring with an electric strap, thereby making it possible to fix the wiring more firmly. It relates to a clamp for wiring.

In general, automobiles are composed of complex and sophisticated devices and components, and in order to supply electricity to such devices and components, it is necessary to simplify the complicated wiring in a narrow internal space, and in case of maintenance obstacles caused by the wiring. The wiring must be secured in an appropriate position so that there is no gap, and the insertion and support of the wiring should be good.

1 is a perspective view showing a state of use of a conventional wire fastening clip, in which a plurality of wires have circular mounting holes 14 on the upper side and support pieces 13 having a predetermined length on both sides of the lower wire. The electrical wiring clip 12 integrally formed is brought into close contact with each other, and the support piece 13 and the wiring 11 are taped together using a tape 16 to fix the wiring and the clip to the mounting hole 14. It was fixed to the vehicle body 10 using a bolt through.

However, as the above-described clip for fixing the wire is taped in multiple layers, the work time is excessive and the appearance is poor, and the tape is inadvertently attached because several clips are attached to one wire at regular intervals. This eccentricity and twisting occurs in the wiring when the clip is fixed to the vehicle body.

In addition, due to the twisting of the wiring, a heavy load was repeatedly applied to the clip in a state in which the clip is mounted on the vehicle body, and cracks often occur around the mounting hole of the clip.

Accordingly, the present invention is conceived in view of the above, by forming a clip portion of a curved wiring contact portion and a strap-shaped strap of a certain length in the lower portion, by closely contacting the wiring to the wiring contact portion and tying the wiring with a strap The purpose of the present invention is to provide a clamp for fixing an electric wire that can be fixed firmly, and an upper portion of the anti-torsion rib is formed up and down to form an empty space between the ribs, thereby reducing the load when a load is generated due to the twisting of the wire. It is.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the electric wiring clamp fixed to the vertical body panel screw, the reinforcing ribs 20 are formed to be inclined to both the upper and lower horizontal sides of the body 15 of the type having a screw mounting hole in the upper portion, and from the lower portion of the body to the inside An elongated arc-shaped wire contact portion 26 is formed, and an elongated strip-shaped strap 24 is integrally formed at the center of the wire contact portion 26, and the strap is centered at the lower edge of the body 15. It is characterized by forming a strap fixing portion 28 for fixing through (24).

In addition, the strap 24 is characterized in that the teeth 32 are formed on the inner surface over a predetermined length.

In addition, the strap fixing portion 24 is formed by the insertion hole 30 is vertically penetrated to protrude, the teeth 32 of the strap 24 is fixed to the inner surface of the fitting hole 30 It is characterized in that the projections are formed.

The hole 33 is formed on the vertical fitting hole 30 so that the free end of the strap 24 can be inserted.

The present invention is described in more detail as follows.

2 is a perspective view showing a state of use of the clamp for electrical wiring according to the present invention, wherein the strap fixing portion 28 of the rectangular body protrudes outward from a portion below the front surface of the mold body 15 of the clamp 18. It is formed, penetrating vertically through the upper and lower center surface of the strap fixing portion 28 is formed a thin long rectangular fitting hole 30, the locking projection is formed inside the fitting hole.

Wiring contact portions 26 are formed on both lower side surfaces of the clamp 18 from the bottom of the front surface of the body 15 to the center of the rear surface of the clamp 18, and the back side of the strap fixing portion 28 and the inner side of both wiring contact portions 26. A predetermined length of one side end is brought into contact with the surface, and an elongated belt-shaped strap 24 is formed in which the teeth 32 are formed on the inner surface.

Therefore, the wires 11 of several strands are brought into close contact with the wire contact portion 26 and wrapped with a strap 24 to insert the other end of the strap into the fitting hole 30 of the strap fixing portion 28 and pulled by hand. The teeth 32 of the strap are caught by projections formed inside the fitting hole 30 so that the wiring 11 is firmly fixed.

In addition, lower ribs 22 inclined downward toward the front surface are formed on the wire contact portion 26 of the clamp 18, and on the lower ribs 22, there is a horizontal surface of the body 15 of the mold, and the front surface is above both sides of the horizontal surface. To form a triangular reinforcing rib 20 downwardly

The upper vertical surface of the body 15 of the clamp 18 is in contact with the horizontal surface of the body and the back of the reinforcing rib 20 and has a circular mounting hole 14 on the top, the upper border is formed in a curved surface.

Herein, an inner space is formed between the lower ribs 22 on both sides, and an outer space is formed between the upper reinforcing ribs 20, so that the space between each of the upper and lower ribs and each rib is loaded when a load is generated due to twisting of the wiring. It will function to reduce.

In addition, a square in the center of the lower surface of the body 15 of the clamp 18 to secure the wiring 11 and to handle the predetermined length portion of the strap 24 to come out through the fitting hole 30 of the strap fixing portion. Holes 33 are formed.

As described above, according to the clamp for fixing the wire according to the present invention, there is an advantage that an operator can easily work by tying the wire with a strap.
