Description

[Detailed description of the invention] ``Field of industrial application'' The present invention relates to a harness band for binding and holding wiring harnesses inside an automobile body or harnesses of electrical equipment, etc., and specifically relates to harness bands with improved resin moldability. Regarding the band.

``Prior Art'' Conventionally, a resin harness band shown in FIG. 8 has already been provided.

The harness band shown in FIG. 8 consists of a band body 1 and a head part, the band body 1 has a large number of engaging parts 2 at regular intervals on its surface, and the head part 3 has claws 5 on its inner surface. A through hole 4 is formed.

Such a harness band is constructed by wrapping a band 1 around a tied harness and inserting the band 1 into a through hole 4 of a head 3.
Then, the engaging part 2 and the claw 5 are engaged with each other and fixed at an appropriate location on the harness.

Another conventional technique is a harness clip disclosed in Japanese Utility Model Publication No. 13269/1983.

In the case of this known example, one end of a belt-shaped clip having a plurality of through holes is bent inward, and a hook is formed at the inward end of the belt-shaped clip to be able to engage with the through-holes, and A leg portion with a vertical slit that can be expanded and contracted in the radial direction projects from the outer surface of one end of the band-shaped clip.

In this known example, a band-shaped clip is wound around a harness, and the hook and the through-hole are relatively engaged to fix the band-shaped clip at an appropriate position on the harness, and then the legs are inserted into the panel hole. Secure the harness in place with the strap clips.

``Problems to be solved by the invention'' The harness band shown in Fig. 8 can hold the harness at any point in the longitudinal direction of the harness, but simply holding the harness with the harness band will not allow the harness to be held in place during use. Misalignment movement,
Problems such as damage to the harness cannot be avoided.

On the other hand, in the publicly known example of Utility Model Publication No. 55-13269, the belt-shaped clip has legs, and by inserting the legs into the panel holes, the stability of the harness fixation state is obtained, and the above-mentioned problems are avoided. Hard to happen.

However, in the case of this known example, various structures are concentrated in the band-shaped part of the clip, and even the legs are added to it, so when making this by resin molding, the design of the mold is Make it complicated.

In particular, since the leg portions have a structure to prevent them from coming off from the panel holes, the mold design becomes more complicated, and the mass production of honey bands or honey clips is hindered.

In view of the above-mentioned problems, the present invention aims to provide a harness band that not only securely holds the harness but also avoids complicating the mold design and is excellent in mass production.

``Means for Solving the Problems'' In order to achieve the intended purpose, the harness band according to the present invention has a head equipped with an elastically bending claw and an engagement groove that engages with the claw. A flat plate extending perpendicularly to the axial direction of the band is formed in the middle of the band in the axial direction, and on both end surfaces of the flat plate, The vertical plate and the engagement piece are formed parallel to each other and perpendicular to the surface of the band portion, and the external surface of the vertical plate is formed with a leg portion having a locking portion projecting in the radial direction. In addition, an engaging claw for engaging the upright plate is formed inward at the end of the engaging piece.

"Example" Hereinafter, an example of the harness band according to the present invention will be described with reference to the drawings.

In the embodiment shown in FIGS. 1-4, the harness band 10 is made of a flexible material and consists of a head 11 and a band 12 that are interconnected.

The head 11 has a through hole 13 formed therein, and a holding piece 15 equipped with an elastically bending pawl 14 is formed at the center of the inner surface of the through hole 13. protrudes outward from the through hole 13, and on the inner surface of the through hole 13 facing the claw 14, a plurality of protrusions 16 are provided parallel to each other along the penetrating direction of the through hole 13.

Holding piece 15 and protrusion 16 in the through hole 13
There is a space between them that is sufficient for the band 12 to pass through, and the holding piece 15 is configured to bend when the band 12 passes.

The band portion 12 includes, on the outer surface of one end of the head 11,
The band portion 12 extends in a direction perpendicular to the through hole 13, and is located in the middle of the band portion 12 in the axial direction.
A flat plate 18 extending perpendicularly to the axial direction is formed in a cross shape, and on both end faces of the flat plate 18, a standing plate 19 and an engaging piece 21 are provided in parallel with each other, and the above-mentioned band surface It is formed at right angles to the

A large number of engagement grooves 17 are formed on one surface of the band 12 from a position slightly away from the flat plate 18 toward the end of the band to near the end of the band.

These engagement grooves 17, which can be freely engaged with the claws 14, each have a depth that allows the claws 14 to engage, and a width that allows the claws 14 to fully bite into them.

The standing plate 19 of the band portion 12 has a thin rising portion as a bendable hinge body 20, and the outer surface of the standing plate 19 has legs provided with a plurality of locking portions 24 projecting in the radial direction. The portion 23 is formed,
The leg portions 23 protrude from the outer surface of the standing board 19 at right angles.

In this case, the plurality of locking portions 24 have an umbrella shape that becomes sharp toward the distal end of the leg portion 23, and these locking portions 24 are arranged in multiple stages in the axial direction of the leg portion 23.

At the center of the engagement piece 21 of the band portion 12, an engagement claw 22 for engaging the upright plate 19 is formed toward its inner surface, and the engagement claw 22 has a triangular shape.

In the flat plate 18, a extraction hole 25 is bored in a portion immediately below the engagement claw 22, which is the same height as the engagement claw 22 or slightly larger than that.

Next, the harness band 10 of the above-mentioned embodiment
An example of binding and fixing a harness bundle through a harness will be described with reference to FIGS. 5 and 6.

The harness band 10 before use is shown in Figures 1 to 4.
The state shown in the figure is shown, and the upright plate 19 is attached to the belt part 1.
Standing at right angles to 2.

In this state, when the upright plate 19 is first folded down from the hinge body 20 toward the engagement piece 21 and the tip of the engagement claw 21 is locked by the engagement claw 22, the state as shown in FIG. 5 is obtained. As a result, the legs 23 on the outer surface of the standing board 19 are
Climb onto it in a manner perpendicular to it.

In this case, the engaging claw 2 that locks the engaging piece 21
Unless 2 is intentionally removed, the legs 23 will not be attached to the belt 12.
held on top.

Next, as shown in FIG. 5, the harness bundle 26 is crossed over the belt part 12 and placed on its lower surface, and the belt part 12 is curved in that state, and the end of the belt part is attached to the head part as shown in FIG. 11 into the through hole 13.

Note that the amount by which the belt portion 12 is pulled through is the same as that of the harness bundle 26.
Since the outer diameter of the belt 12 can be determined freely, the belt 12 is tightened until the harness bundle 26 is tightened by the belt 12.

At this time, the claws 14 provided on the holding piece 15 engage with the plurality of engagement grooves 17 provided on the band portion 12, but when the harness bundle 26 has been tightened, the claws 14 and the engagement grooves 17 are engaged with each other. The engagement groove 17 engages with the claw 14 to maintain the tightened state.

Regarding the relationship between the engagement groove 17 and the pawl 14, since the pawl 14 acts elastically together with the holding piece 15,
The claw 14 is pressed into the engagement groove 17, but
The holding piece 1 is moved in the direction of removing the claw 14 from the engagement groove 17.
5 is bent, the engagement groove 17 and the pawl 14 separate from each other and the tightened state is released.

After the harness band 10 is attached to the outer periphery of the harness bundle 26, the legs 23 are inserted into well-known panel holes as shown in FIG.

A plurality of identical locking portions 24 are formed on this leg portion 23, but these locking portions 24 are for freely absorbing the thickness of the panel, and regardless of the panel thickness, The locking portion 24 is relatively locked with the panel hole.

The harness bundle 26 fixed in this way does not shift or move inadvertently, and therefore, when used with the harness band, it satisfactorily fulfills its predetermined function.

FIG. 7 shows a screw hole 27 that replaces the panel hole, and the screw hole 27 has an uneven inner surface.
is formed on a protrusion of the mounting boss 28.

The leg portion 23 can also be locked at a location having such a screw hole 27.

Next, the advantages of the harness band according to the present invention over the conventional example in terms of mold production will be explained.

Generally, in the case of a harness band in which the legs are integrally provided (for example, Japanese Utility Model Publication No. 13269/1983),
The leg portion is formed as a protruding structure that stands perpendicular to the band portion, and a portion that always engages with the panel hole (such as the aforementioned locking portion 24 when it falls down) is integrally formed on the leg portion. .

This protruding portion cannot be removed by simply opening the upper and lower molds in a normal resin molding die, but only the protruding portion is opened by a slide core in synchronization with, or before or after, the opening of the mold.

For this reason, not only does the mold structure become more complicated, but the slide core enters between the molds (upper mold and lower mold) and moves left and right between these two molds, making it impossible to produce only small quantities with ordinary molds. When making a mold for mass production, this mold becomes large.

The harness band 10 according to the present invention has leg portions 23
is formed on the outer surface of the standing plate 19, and the mold can be moved entirely by vertical action with respect to the band portion 12.
The mold space can be used effectively and the mass production effect can be achieved.

Of course, when the upright plate 19 is locked by the engagement piece 21, the legs 23 on the outer surface of the upright plate 19
2, the harness band 10 can be used in this manner in the same manner as when the legs 23 are provided directly on the band portion 12.

``Effects of the Invention'' As explained above, the harness band according to the present invention has a standing plate formed at a predetermined position of the band portion and perpendicular to the standing plate, and legs are formed on the outer surface of the standing plate. Since the legs are parallel to the surface of the strap, the structure of the mold for resin molding the harness band is simplified, and a large number of harness bands can be molded in the same mold at the same time. In addition, by locking the upright plate with the engagement piece and making the legs on the outer surface of the upright plate perpendicular to the band, the harness band can be used in a normal manner and performs a predetermined harness holding function.
