JPS6011339Y2 - Strap fastener for cable - Google Patents

Description

[Detailed description of the invention] This invention is applicable to cables, wires, pipes and the like (hereinafter referred to as 1 cable).

) to a panel such as a partition panel between an automobile engine and a passenger compartment.

This kind of strap fastener was made in 1985-14070.
It is known from the publication No.

This is a dish-shaped flange with a mounting shaft protruding from the center of its inner surface that is pushed into a hole in the panel, one end of the band is integrally connected to the outer surface of the flange, and the other end of the band is fitted into the mounting shaft. A ring is provided.

Therefore, to bundle and secure cables to a panel with a strap, the strap is wrapped around the cable, the ring is fitted onto the mounting shaft, and the mounting shaft is then pushed into the hole in the panel.

However, with this method, the cables are bundled by fitting the ring at the other end of the strap onto the mounting shaft, so to accommodate changes in the length around the cable to be wrapped, straps with different lengths are prepared. There is a need to.

Furthermore, since the ring is fitted onto the mounting shaft and then the mounting shaft is pushed into the hole in the panel, the ring is interposed between the panel surface and the underside of the flange, making it impossible to prevent water from entering the panel hole. .

Therefore, the cable strap fastener of the present invention is made of plastic, and has a mounting shaft that protrudes from the center of the inner surface of the dish-shaped collar and is attached by being pushed into a hole in the panel, and a mounting shaft that extends from the center of the outer surface of the collar in the opposite direction to the mounting shaft. a protrusion that projects integrally and has an enlarged head at the tip; and a U-shaped part at one end that straddles the protrusion, and the U-shaped part straddles the protrusion and is integrally connected to the outer surface of the tsuba. The band portion is characterized in that the band portion has holes scattered along the longitudinal direction into which the projection portions enter.

Therefore, according to the present invention, the mounting shaft is pushed into the hole in the panel,
Since the peripheral edge of the dish-shaped collar is pressed against the surface of the panel, it is possible to reliably prevent water and dust from entering the holes in the panel.In addition, the strap is wrapped around the cable, and the appropriate hole in the strap is attached to the flange. Since the cables are bundled by passing through the protrusion on the outer surface of the cable, it is possible to accommodate changes in the length of the cable by selecting the hole through which the protrusion passes depending on the circumference of the cable.

An embodiment of the present invention will be described below with reference to the drawings.

The illustrated strap fastener has a mounting shaft 11 that engages a hole in panel A to which one or more cables B are attached.

The mounting shaft portion 11 includes a shaft 12 with a circular cross section, and four rows of blades 13 protruding outward in the radial direction from around the shaft 12 in a cross shape.
・Consists of 14...

The two rows of back-to-back blades 13 and 14 are offset in the axial direction of the shaft 12.

The mounting shaft portion 11 protrudes from the center of the inner surface of the dish-shaped collar 15.

The flange 15 elastically presses against the surface of the panel to which the mounting shaft part 11 is attached, and prevents dust and water from entering the hole in the panel.

A protrusion 16 is provided at the center of the outer surface of the collar 15, protruding in a direction opposite to the mounting shaft.

The protrusion includes a shaft 17 with a circular cross section, and an enlarged head at the tip of the shaft, and a shoulder 18 on the lower side of the waisted head.

The band portion 19 straddles the protrusion 16 and is connected to the outer surface of the collar 15.

Reference numeral 21 denotes a U-shaped portion provided at one end of the band to straddle the protrusion 16, and there is a space 20 between the U-shaped portion and the protrusion.

There is a jagged knob 22 at the other end of the strap, and a number of holes 23 are dotted along the length.

These holes 23 are relatively close to each other.

- By way of example, the thickness of the band is approximately one-fifth of the diameter of the hole.

As is clear from FIG. 2, the thickness of the portion 19' of the band between the collar 15 and the portion having the hole 23 is thinner than other portions, making it easier to bend.

The fastener is made from a single molded piece of any suitable material, such as nylon 60 or other suitable polyamide.

To use, push the mounting shaft 11 into an appropriately sized hole in panel A, and remove the blades 13.1 that protrude from around it.
4 grips the panel to prevent it from coming off, and the peripheral edge of the collar 15 is brought into pressure contact with the surface of the panel to prevent lumps and moisture from passing through.

Next, the band part 19 is folded to the left or right as seen in FIG. Wrap the belt around the hole 23 so that one of the holes 23 is connected to the protrusion 16.
The protrusion 16 is pushed into the hole 23 to hold the band 19 in that state as shown in FIG.

Since the holes 23 are spaced close to each other, even if the length around the cable to be wound changes, the holes 23 can be finely adjusted even if the length around the cable to be wound changes.
It fits perfectly in 6.

Then, due to the spring force of the fallen band trying to rise to its original state, the edge of the hole 23 through which the protrusion 16 passes is firmly pressed against the stop shoulder 18 on the lower side of the enlarged head at the tip of the protrusion. press

Since the band part 19 is provided with a space 20 by a U-shaped part 21 in the part connected to the collar 15, the protrusion part 16 can be formed in the space, and this article can be molded using a two-piece mold.

Further, by making the mounting shaft part have the structure shown in the figure, this strap fastener can be mounted to panels of various thicknesses.

This strap fastener can also be used to hold cables that vary widely in size.
