Description

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

In conventional plating hangers, in order to secure the branch rod to the main rod, a predetermined number of holes are drilled in the main rod, the branch rod is inserted into the neck hole, and then the branches are welded or crushed. 1,
However, when doing this, it takes a lot of time and money to manufacture one plating hanger, and there are also disadvantages such as the fact that the branch rods move in the axial direction, resulting in poor fixation.

Therefore, the applicant of the present application first welded a predetermined number of branch rods intersecting at least one or more vertical rods, and
For plating, a clip member is provided at an appropriate location on the vertical rod so as to cover the vertical rod and the main rod, and the clip member, the vertical rod, and a branch rod portion near the vertical rod are driven into and fixed to the main rod. /' + Ngar (Special Publication No. 57-33: 358).

However, if only the vertical rod and the branch rod were made to intersect, a large force would be applied to the intersection of the two when the two were driven and fixed, resulting in the vertical rod or the branch rod breaking or bending.

The present invention aims to solve these drawbacks, and aims to provide a plating hanger that can firmly fix the main rod and the branch and has higher precision.

In the present invention, a predetermined number of branch rods are welded so as to intersect with at least one vertical rod so as to be on the same plane as the vertical rod, and the vertical rod and the main rod are attached to appropriate positions of the vertical rod. A clip member is provided to cover the main rod, and the clip member, the vertical rod, and the branch rod portion near the vertical rod are driven into and fixed to the main rod.

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

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 copper main rod with a hook shape 1a on the top, 2... are elastic branch rods made of stainless steel, etc., the tips of which are covered. It is processed as appropriate to suit the plated item.

3, 3 is a stainless steel vertical rod, and 4 is a stainless steel clip member formed in a U-shape in cross section.

This clip member may be made of copper instead of stainless steel.

Further, the vertical rods 3, 3 can also be made of metal other than stainless steel, as long as they can be welded to the branch rods 2.

To manufacture a plating hanger from each component,
First, a predetermined number of branch rods 2...
・ are provided at appropriate intervals, and the intersection points P of the two are welded by spot welding etc. so that the center lines of the vertical rods 3, 3 and the center lines of the branch rods 2, etc. are on the same plane (Fig. 1) B and Figure 2).

Next, the welded vertical rods 3, 3 of the branch rods 2... are placed on the main rod 1, and the vertical rods 3. In the covered state, the clip member 4...
(see Fig. 1B), and in that state, press from above and below to attach the clip members 4..., the vertical rod 3゜3, and the branch rod 2... portion near the vertical rod to the main rod 1. Drive it into place and secure it (see Figure 3B).

After driving, the entire branch rod 2 except both ends is coated with an insulating resin coating 5 as shown by the chain line in FIG. 3A.

The clip members 4 may be provided at the longitudinal center of the vertical rods 3, 3, as shown by 4a+4b in FIG. 4, for example, in addition to the aforementioned two ends of the vertical rods.

In particular, if it is provided so as to cover the intersection point P between the vertical rod 3.3 and the branch rod 2, as shown in 4b, the branch rods 2 can be more firmly fixed to the main rod 1 by driving.

Further, although two vertical rods are used in the above embodiment, only one vertical rod may be used as shown in FIG. 3, or three or more vertical rods may be used.

When two or more vertical rods are used, a quadrilateral closed loop surrounded by the vertical rod 3゜3 and the branch rods 2... is formed as shown by a... in Fig. 3, so the copper is removed during driving. It has a good buildup and can be fixed more firmly.

That is, during driving, the vertical rods and branch rods that make up the closed loop are strongly fixed by receiving lateral force due to the copper that has entered into the closed loop a..., and the remaining copper is firmly fixed to the vertical rods and branch rods. Since it rises to the top, it becomes even more firmly fixed.

Also, even if there is only one vertical rod, three vertical rods are used as shown in Figure 5.
If bent parts 6, 6 are formed at both ends of the
, 6 have the same effect as the closed loop described above and have good copper buildup, so they can be firmly fixed.

As described above, in the plating hanger according to the present invention, a predetermined number of branch rods 2 are welded so as to intersect with at least one or more vertical rods 3 so as to be on the same plane as the vertical rods. At the same time, clip members 4 are provided at appropriate locations on the vertical bars 3, 3 to cover the vertical bars 3, 3 and the main bar 1, and the clip members 4, the vertical bars 3, 3, and the vicinity of the vertical bars are provided. Since the branch rod part of the rod is driven into the main rod 1 and fixed, it has the following effects.

'First of all, the vertical rods are welded with branching rods and are fixed by driving them into the main rods, so they are firmly fixed.Furthermore, because the main rods, vertical rods, and branch rods are in close contact, there is no electric charge. Low resistance and good conductivity.

Since the clip member is driven from above the vertical rod, the branch rod and the vertical rod are driven deeper and reliably into the main rod by the clip member.

In addition, all branch rods are welded to the vertical rods, so in the unlikely event that
Even if poor conductivity occurs between the main rod and some of the branch rods, conduction will occur through other branch rods, so there is no risk of the object being plated being damaged.

Since a predetermined number of branch rods are welded to the vertical rod and fixed by driving them, all the branch rods can be fixed to the main rod at one time, reducing the number of manufacturing steps.

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, there is no large force applied to the intersection of the vertical rod and branch rod. The rods or branch rods rarely break or bend, making it possible to obtain highly accurate plating hangers.
