JPS5822557B2 - Hanger for plating - Google Patents

Description

[Detailed description of the invention] The present invention relates to a plating hanger.

This kind of plating hanger hooks or clamps the object to be plated on the end of the branch rod, and in order to conduct current from the main rod to the object to be plated through the branch rod, the branch rod is strong against the main rod without wobbling. It is required that the electrical contact resistance be as low as possible.

For this reason, the present applicant first proposed a new technique in which a horseshoe-shaped bent part is formed in the branch rod, and the part of the branch rod that includes this bent part is driven and fixed to the main rod. -1
No. 40239), the above-mentioned problems were solved.

However, in this technique previously proposed by the present applicant, the branch rod itself must be bent to form a bent part, so the processing work is relatively separate, and each branch rod is driven into the main rod and fixed. Until they are installed, they are mutually independent units, so when driving into the main rod, the posture of each branch rod must be fixed so that it does not move or shift, making the driving process complicated. be.

In addition, the applicant welds a predetermined number of branch rods so as to be on the same plane as the vertical rod, intersecting with the vertical rod having bent portions at least on both ends, and also welds the vertical rod and its vicinity. We proposed a technique in which the branch rod part of the rod is driven into the main rod and fixed (Japanese Patent Application No. 135457/1983).

However, if the branch rod and vertical rod are simply crossed and welded together, a large force is applied to the intersection when driving into the main rod, resulting in breakage or bending of the branch rod or vertical rod. .

Therefore, the present invention proposes a useful plating hanger that solves the above-mentioned operational disadvantages while retaining the advantages of the previously proposed technology, namely, low electrical resistance and strong attachment to the main rod. That is.

That is, in the present invention, a predetermined number of branch rods are welded so as to be on the same plane as the vertical rod in a state where they intersect with a vertical rod having bent portions formed at least on both ends, and the vertical rods and the vicinity thereof are welded. For plating, the branch rod part is driven into the main rod and fixed.
The purpose is to provide

Note that the predetermined number of branch rods herein refers to the total number of branch rods to be fixed to one plating hanger Q.

Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows an example of this, in which 1 is a main rod made of copper with a hook shape 1a on the top, 2... are branch rods made of stainless steel, and both ends of the rods are processed as appropriate to suit the object to be plated. .

3 is a vertical rod made of stainless steel, for example, with circular bent portions 4 and 5 formed at both ends.

To manufacture a plating hanger from each component, first, a predetermined number of branch rods 2 are installed at appropriate intervals so as to intersect with the vertical rod 3 (as shown in Figure 1). , the intersection point p between each branch rod 2... and the vertical rod 3 is the branch rod 210. (See Figures 2 and 3B).
Next, this vertical rod 3 and the portions of the branch rods 2 in the vicinity thereof are driven into the main rod 1 using a press or the like and fixed (see FIG. 3B).

After driving, the entire branch rod 2 except for both ends is coated with an insulating resin film 6 as shown by the chain line in FIG. 3A.

Note that the bent portions 4 and 5 at both ends of the vertical rod 3 may be formed in a triangular shape, for example, as shown in FIG. 4, instead of being circular as described above.

Further, the bent portions only need to be formed at least at both ends of the vertical rod, and therefore, for example, a vertical rod whose entire structure is bent into a meandering shape as shown in FIG. 5 can also be used.

As described above, the plating banger according to the present invention has a predetermined number of branch rods 2... which are welded in a state that intersects the vertical rod 3 having bent portions 4 and 5 formed at least at both ends. Since the vertical rod and the branch rod portions in the vicinity thereof are driven and fixed to the main rod 1, it has the following effects.

First, a predetermined number of branch rods are welded to the vertical rod in advance, and these are driven into the main rod and fixed, so that all the branch rods can be driven and fixed to the main rod in one driving operation.

Moreover, since all the branch rods are welded to the vertical rods and the mutual posture of the branch rods is fixed, the branch rods do not move independently or become misaligned during driving.

Furthermore, since the vertical rod has bent portions at least at both ends, the branch rod can be firmly fixed to the main rod with low electrical resistance.

In other words, the bent part receives lateral force from the copper that enters the space surrounding the bent part during driving, and is firmly fixed with good contact, and the remaining copper rises upward and bends. Since it rests on the upper part of the rod, the conductivity between the main rod, the vertical rod, and eventually the branch rods is improved, and they are firmly fixed.

Furthermore, since the vertical rod and branch rod are welded so that they are on the same plane and are driven into the main rod and fixed, large forces are not applied to the intersection of the vertical rod and the branch rod.
There is almost no chance of the vertical or branch rods breaking or bending, making it possible to obtain highly accurate plating bangers.
