Description

[Detailed Description of the Invention] The present invention relates to an electric wire bundle binding tool for binding electric wire bundles, conduits, etc.

Conventionally, there are a relatively large number of binding tools made of flexible materials. For example, as shown in Utility Model Application Publication No. 39491 of 1972, a substrate is connected to a strip protruding from one end of the substrate, and this strip is engraved with a ratchet gear type tooth row. , an electric wire bundle binder is disclosed in which the wire bundle is bound by meshing the band-like piece with a ratchet stopper mechanism carved into the ceiling of a substantially tunnel-shaped portion formed on a substrate.

As is clear from its mechanism, the conventional electric wire bundle binding device as described above has the disadvantage that it is relatively difficult to create a mold for it because the ratchet stop mechanism is formed within the tunnel-shaped portion. .

The purpose of the present invention is to provide two through holes in a substrate side by side with a gap of an appropriate width in between, and to
A strip having a width smaller than the through hole is integrally provided at one end of the substrate, and at least on different surfaces of the strip and the gap, a sawtooth shape is formed with tooth heads facing in opposite directions. The present invention aims to solve the above-mentioned drawbacks of the conventional electric wire bundle binding device by providing a required number of protruding jetties.

The contents of the present invention will be explained in detail below based on embodiments shown in the drawings.

FIG. 1 is a plan view showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a binding device main body made of a flexible synthetic resin material, and this binding device main body 1 has a substrate 2 and one side of this substrate It consists of a strip 3 etc. that are integrally connected to the end. The substrate 2 is formed in a horizontally long rectangular shape, and a gap 4 of an appropriate width is provided in the center of the substrate 2.
Two rectangular through holes, a first through hole 5 and a second through hole 6, which are substantially the same in shape, are arranged in parallel along the longitudinal direction of the substrate 2 (see FIG. 2) and have substantially the same shape. On the upper surface side of the gap 4 of the substrate 2, a sawtooth-like protrusion 7 in a direction perpendicular to the longitudinal direction of the substrate 2 is provided with a predetermined number of steps with its tooth heads 7a projecting in the direction of the band-shaped piece to be described later. As shown in FIG. 3, on the lower surface side of 2, there are guide grooves 8, 8 that lead from both outer edges in the longitudinal direction of this substrate to upper openings 5a, 6a of the first through hole 5 and the second through hole 6, respectively. As shown in FIG. 2, the notch is formed to have the same width as the through holes 5 and 6 so as to have an eight-shaped cross section.

The length of the strip 3 is determined as appropriate in consideration of the wire bundle, the thickness of the conduit, etc., but its width must not be larger than the width of both through holes 5 and 6 bored in the substrate 2. It is formed in width.

A jet 9 having the same shape as the serrated jet 7 formed on the upper surface of the gap 4 of the base plate 3 is provided on the lower surface of the strip 3 in a required number of stages with the tooth head 9a facing toward the base 2. There is. That is, the serrated ridges 7 and the serrated ridges 9 are respectively protruded from opposite surfaces of the binding device main body 1, but their respective tooth heads 7a and 9a are formed in the direction of the opposing surfaces.

Further, the tip of the free end of the strip 3 is formed into a gently curved surface from the upper surface side to the lower surface side so that it becomes thinner as it goes forward.

The configuration of this embodiment is as described above, but to explain its use, first, the upper surface of the strip 3 (the surface on which the serrated jetty 9 is not formed) is curved and wound around the wire bundle D. do. Then, the tip of the strip 3 is inserted through the lower opening 5b of the first through hole of the substrate 2, passed through the upper opening 5a, and then further inserted into the lower opening 6a of the second through hole 6. 6
Penetrate it toward b. At this time, the through hole 5,
By making the guide grooves 8, 8 attached to part 6 and the tip of the strip 3 into a thin plate shape, the tip of the strip 3 can be inserted almost straight into the through holes 5, 6, making it easy to perform the bundling work. have advantages. However, when the tip of the strip 3 is further advanced, the wire bundle is bundled,
At this time, the serrated protrusions 7 and 9 protruding from the substrate 2 and the strip 3, respectively, mesh with each other, and the tip of the strip 3 is engaged with the substrate 2. At this time of attachment,
At the meshing location of both sawtooth-shaped projections 7 and 9, the strip 3 receives a pressing force toward the substrate 2 side by the wire bundle D that is wrapped around it. 9 can be more firmly interlocked.

FIG. 5 shows another embodiment of the present invention,
Both sides of the gap 14 of the substrate 12 and the strip 1
Serrated ridges 17, 19 are formed on the upper and lower surfaces of the tooth 3, respectively, and tooth heads 17a, 19, respectively.
A is also formed to face in the opposite direction.

According to this embodiment, no matter which side of the strip 13 is used to bind the wire bundle, it can be meshed with the sawtooth protrusions 17 on the substrate 12, so that the binding operation can be easily performed. In this embodiment as well, it is desirable to form guide grooves 18 having the same effect at the positions of the through holes 15 and 16 as in the previous embodiment.

As explained above, in the present invention, the through holes are provided in parallel on the substrate, and the sawtooth-like protrusion is provided protrudingly in the gap between the two through holes, and on the other hand, the surface of the strip continuous to the substrate is Since it is formed by forming a jetty that meshes with a serrated jetty protruding from the mold, there is no inwardly bent part when creating the molding frame, so it can be molded very easily. Also, when bundling wire bundles, etc., the meshing part will receive the pressing force of the wire bundle, so
This has an excellent effect in that the mesh is more firmly engaged and the band piece does not come off from the board and the wire bundle is not untied.
