Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a clip that is attached to a stud that is welded onto the body of an automobile or the like.

[Prior art and its problems]

Pipes are made using Christmas tree-style studs or G studs that are welded onto the car body.
Various types of clips are known for use in attaching harnesses, rods, cables, etc. to the body. For example, there are known clips that use a nut that can be attached to a welding stud with one touch, and clips that use a nut that fits or screws into a stud.

Although these conventional clips watertightly seal the welded portion of the stud, they are insufficient to prevent body corrosion caused by weld spatter that occurs during stud welding. Therefore, conventionally, a process of removing welding spatter is required, and if this process is attempted to be automated, the work process becomes complicated and costs increase. Another prior art solution involves welding in an inert gas atmosphere, but in this case, a large area is required for the welding surface, and securing the welding surface of the automobile body becomes a problem.
Due to the body layout, it may not be possible to secure a welded seat surface.

[Purpose of invention]

The object of the present invention is to provide an anti-corrosion clip that solves all of the above-mentioned problems of the prior art.

[Structure of the idea]

In order to achieve this object, the present invention is a clip that is attached to a stud that is welded onto the body of an automobile, etc., and is designed to be installed around the stud, and is a hollow hole having a means for supporting the supported article on its outer surface. A clip comprising a tubular clamp part and a nut part having an inner diameter hole that fits or screws into a stud and cooperates with the stud to fix the clamp part, the clamp part or The present invention provides a clip characterized in that the nut portion or both of these portions are provided with anti-corrosion means.

In a preferred embodiment of the present invention, the anti-corrosion clip has a nut portion made of synthetic resin, and has a resilient locking pawl projecting obliquely upward within its inner diameter hole, and the anti-corrosion means is configured to engage this locking claw. It is characterized by including an anti-corrosion element insert-molded into the nail.

In another preferred embodiment of the present invention, the anti-corrosion clip is characterized in that the clamp part and the nut part are all made of synthetic resin, and a powdered anti-corrosion material is mixed into the synthetic resin during molding.

In another preferred embodiment of the invention,
The anti-corrosion clip is characterized by having an anti-corrosion element embedded in the end surface of the nut that comes into contact with the body.

In yet another preferred embodiment of the invention, the anti-corrosion clip is characterized in that an anti-corrosion element is embedded in the end face of the clamping part that comes into contact with the body.

In yet another preferred embodiment of the present invention, the anti-corrosion clip has a part of the nut part that cooperates with the stud made of metal, and this metal part is covered with a synthetic resin outer shell, and the metal part and the outer shell are made of metal. A feature is that an anti-corrosion element is installed in between.

[Functions and effects of the invention]

According to the above configuration, the anti-corrosion means acts directly or indirectly on the body surface to exhibit a rust-preventing effect. Therefore, it is no longer necessary to take the trouble to remove welding spatter or to perform welding in an inert gas atmosphere.

〔Example〕

Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings.

First, referring to FIGS. 1 to 3, there is shown a clip which is a first embodiment of the present invention.
This clip has studs 1 welded onto body 10.
A hollow tubular clamp part 14 installed around 2
and a nut portion 18 that can be inserted into the inner diameter hole 16 of the clamp portion 14 and cooperates with the stud 12 to fix the clamp portion 14 to the body 10.

The clamp part 14 has a support means 1 that supports a supported article 20 (pipe in the figure), similar to the conventional structure.
It has 4A.

The nut portion 18 shown here consists of a head 22 and a stem 24 extending from the head, and is entirely made of synthetic resin. An inner diameter hole 26 is provided passing through the nut portion 18 in the axial direction, and this inner diameter hole 26
head 22 from near the end farthest from head 22.
A pair of diametrically opposed slits 28 are formed across the end face of the slit 28, and from the end of each slit 28 remote from the head 22, a resilient locking pawl 30 extends obliquely upward toward the inner diameter hole 26. ing.
These locking pawls 30 are adapted to cooperate with circumferential grooves or threads provided on the outer circumferential surface of the stud 12 when the nut portion 18 is mounted on the stud 12. When the nut portion 18 is in its normal operating position, its head 22 engages the end face of the clamp portion 14 and secures the clamp portion 14 to the body 10.

In this embodiment, the stud 12 of each locking pawl 30
An anti-corrosion element 32 is insert-molded on the surface facing the stud 12, and this anti-corrosion element 32 exhibits a rust-preventing effect directly or in close proximity to the stud 12.

Next, referring to FIG. 4, the second part of the present invention is shown here.
An exemplary clip is shown, the structure of which is substantially the same as the clip shown in FIGS. 1-3, and like parts have been given the same reference numerals. In this second embodiment, the nut portion 18 and the clip portion 14 are all made of synthetic resin, and a powdered anti-corrosion material is mixed into the synthetic resin during molding. Therefore, this anti-corrosion clip exerts a rust-preventing effect directly or in close proximity to the stud and body surface.

5 to 7, there is shown a third embodiment of the present invention, in which a stem 41 of a nut portion 40 is provided with an internal bore 42 for cooperating with a stud 12A. However, this inner diameter hole 4
2 does not extend through the head 42, it has substantially the same structure as the previous embodiment, and the same parts will not be described with the same reference numerals. In this third embodiment, the inner diameter hole 42 of the nut portion 40 is threaded, and this thread cooperates with a thread similarly cut on the outer surface of the stud 12A to screw the nut portion 40 onto the stud 12A. Thus, the clamp portion 14 is fixed to the body 10.

An anti-corrosion element 46 is embedded in the end surface of the nut portion 40 that contacts the surface of the body 10 by insert molding, heat caulking, or ultrasonic welding. It exhibits anti-corrosion effect.

Further, referring to FIG. 8, a fourth embodiment of the present invention shown here is almost the same as the third embodiment, but a corrosion protection element 50 is insert-molded on the end surface of the clamp portion 14 that contacts the body surface 10. Alternatively, it differs in that it is embedded by heat caulking or ultrasonic welding. However, this anti-corrosion element 50 also exhibits a similar effect.

Finally, referring to FIG. 9, the fifth embodiment of the present invention shown herein utilizes a nut portion 56 that includes a metal nut body 54 having a head 52. As shown in FIG. In other respects, there is no difference from the third and fourth embodiments. The nut body 54 has a head 52 and a stem 58 extending from the head, with a threaded bore 60 extending axially through the head 52 and stem 58. This inner diameter hole 60 is screwed into the threaded stud 12A to form the clamp part 14.
is fixed to the body 10. The metal nut body 54 is entirely covered with a synthetic resin outer shell 62 except for the end surface that contacts the body 10, and an anti-corrosion element is provided between the outer shell 62 and the head 52 of the metal nut body 54. 64 is insert molded,
This anti-corrosion element 64 indirectly contacts the stud 12A and the body surface 10 via the metal nut body 54, and exhibits a rust-preventing effect.
