Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness fixing band grip capable of reliably preventing rotation of a harness.

[0002]

2. Description of the Related Art A harness grip bandgrip is a fixture for fixing a harness for wiring electronic equipment to an engine room of an automobile or the like. The harness has a plurality of lead wires bundled and housed in a vinyl tube or a corrugated tube, and includes a trunk portion and a branch portion branched from the trunk portion and attached with a connector at the tip. The structure of the harness fixing band grip 21 is shown in FIG. A projecting portion 23 is formed on the back surface side (the side that grips the harness) of one end of the grip body 22. One end of a band 4 for gripping a main line portion (hereinafter, simply referred to as a harness) 10 of the harness is attached to the projecting portion 23. A locking hole 11 for locking the tip of the band 4 is axially formed at the base of the protrusion 23. A fixing piece 8 for fixing the grip body 22 is provided on the surface side of the other end of the grip body 22.

In the harness fixing band grip 21, the band 4 is hooked around the harness 10 and the tip of the band 4 is pulled through the locking hole 11 so as to lock the band in a tensioned state. As shown in FIG. 5, the harness fixing band grip 21 holding the harness 10 is fixed by fitting the fixing piece 8 into the fixing hole 12 provided in the engine room of the automobile.

[0004]

When the harness 10 gripped by the band 4 rotates, the harness branch line 13
Tension is applied to the connector 14, which causes poor continuity in the connector 14. Therefore, the inner surface of the band 4 is notched to prevent the harness 10 from rotating. But,
If the inner surface of the band 4 is notched, the harness 10
The rotation was not sufficiently prevented, and there was a case where the connector 14 failed in conduction. It is an object of the present invention to provide a harness-fixing band grip that reliably prevents the harness from rotating.

[0005]

According to the present invention, a grip body is provided with a fixing portion, one end of a band for gripping a harness is attached to the fixing portion, and the other end of the band is engaged with the fixing portion. In a harness fixing band grip provided with a locking hole for stopping and a fixing piece for fixing the grip body to the grip body, a groove having a C-shaped cross section is formed in the grip body, Section C
A pressing tool for pressing the harness is movably engaged with the groove of the character shape on the groove, and an insertion hole for inserting a band is formed between the pressing tool and the C-shaped cross section groove. It is a band grip for fixing a harness, which is characterized in that

In the present invention, a groove having a C-shaped cross section means
A groove with a narrow opening. The engaging portion between the pressing tool and the C-shaped groove in cross section is formed by, for example, projecting the upper part of the pressing tool on both sides and fitting the overhanging parts on both sides inside the C-shaped groove in cross section. An insertion hole for passing the band is formed between the pressing tool and the C-shaped groove in cross section, the band is passed through the insertion hole in the direction of the fixing portion, and the other end of the band is passed through the locking hole of the fixing portion and pulled. , Lock the band with tension applied. As a result, the harness is pressed against the pressing tool and its rotation is reliably prevented. Since the pressing tool is movable on the groove of the grip body, the pressing tool can be applied to harnesses of various diameters by forming the groove from the fixing portion side toward the other end.

[0007]

In the grip of the present invention, a groove having a C-shaped cross section is formed in the grip body, and a pressing tool for pressing the harness is movably engaged with the groove having the C-shaped cross section. Moreover, an insertion hole for inserting a band is formed between the pressing tool and the C-shaped groove in cross section. Therefore, by wrapping the band around the harness, pulling the tip of the band through the insertion hole of the pressing tool and the locking hole of the grip body fixing portion, and locking the band in a tensioned state,
The harness is pressed by the pressing tool, and its rotation is reliably prevented.

[0008]

[Example] A harness fixing band grip of the present invention,
A specific description will be given with reference to the drawings. 1A and 1B are a plan view and a bottom view, respectively, showing an embodiment of the harness grip bandgrip of the present invention. In the figure, reference numeral 1 denotes a harness fixing band grip (hereinafter abbreviated as a grip), which has a grip main body 2 as a main portion and a fixing portion 3 formed at one end thereof. A locking hole for locking the band is axially formed in the base portion of the protruding portion 23 on the back surface side of the fixing portion 3, and the band 4 is attached to the protruding portion. A fixing piece 8 for fixing the grip 1 to the vehicle body or the like at the other end on the front surface side of the grip body 2.
Is provided. Cross section C on the back side of the grip body 2
A V-shaped groove 5 is formed. A pressing tool 6 for pressing the harness is movably engaged with the groove 5 on the groove 5. The harness is arranged between the pressing tool 6 and the projecting portion 23 of the fixing portion 3 along the groove 5 portion of the grip body 2. The portion of the pressing tool 6 that contacts the harness of the protrusion 23 is tapered so as to make a long contact with the harness.

FIG. 2 is a cross-sectional view of the pressing tool portion of the grip shown in FIG. The pressing tool 6 and the groove 5 having a C-shaped cross section,
The upper end portion of the pressing tool 6 is projected to both sides, and the projecting portions (hinge) 9 are fitted and engaged with both sides inside the groove 5. An insertion hole 7 through which the band passes is formed between the pressing tool 6 and the groove 5.

FIG. 3 is a side view showing an embodiment in which the harness is gripped by the grip shown in FIG. The harness 10 is arranged in contact with the protruding portion 23 of the fixing portion 3, and the band 4 is wound around the lower side of the harness 10 to
The leading end of the band is pulled through the insertion hole 7 formed by the pressing tool 6 and the groove 5 and the locking hole 11 of the fixing portion 3 to lock the band in a tensioned state. This locking is performed by engaging the unevenness (not shown) formed on the tip portion of the band 4 with the claw (not shown) provided in the locking hole 11. The harness 10 gripped by the grip body 2 in this way is provided with the pressing tool 6
The harness 10 is securely pressed against the rotation of the harness 10. If the surface of the band 4, the pressing tool 6, and the fixing portion 3 that contacts the harness 10 is notched, the harness 10
Is more reliably prevented from rotating.

Using the grip of the present invention shown in FIG. 1,
The harness was wired in the engine room of the car and a running test was conducted on a rough road. As a result, rotation of the harness was not recognized at all even in the corrugated portion where rotation was most likely. For comparison, when the same running test was performed on the conventional grip, the harness rotated. In particular, the rotation at the corrugated part was large, and a considerable amount of tension was applied to the harness branch line.

[0012]

As described above, the harness grip band grip of the present invention can reliably prevent the harness from rotating. Therefore, the connector of the harness branch line does not have a poor continuity, and a remarkable effect is industrially achieved.
