Description

[Detailed Description of the Invention] The present invention relates to a conductive member for plating, and more particularly to a plating electrode, a support rod (bus bar) for suspending the electrode, or a support member thereof.

Conventionally, titanium electrodes with a copper core and a titanium-coated outer skin have been used as plating electrodes with an outer skin layer, but with this electrode structure, the workability of titanium is poor, making it difficult to use. It is not possible to obtain irregularly shaped products, and if the shape is unreasonably complicated, the copper material will be exposed, causing roughness and fogging of the plating layer, and it is also expensive.

In view of the above-mentioned conventional circumstances, the present invention solves the problem of the lower condition of conventional electrodes and provides a practical electrode with excellent workability at a low cost. Rather, the purpose is to provide a conductive member that can be applied to bus bars, pillars, etc.

The conductive member of the present invention is characterized in that a conductive metal material is covered with an outer skin layer made of carbon fiber and synthetic resin.

The metal material serving as the core material may be any electrically conductive material such as copper or aluminum, but copper is optimal because of its excellent electrical conductivity and workability.

Further, the metal material may have any shape depending on the purpose, such as a rod shape, a plate shape, a spherical shape, or a frame shape.

The first embodiment of the present invention will be described with reference to the drawings.
The figure shows a plating device, where A is a plating tank, a is an electrode support frame, and is composed of a support 1, a frame rod 2, and a push bar 3, and a plating electrode b is attached to the bus bar 3.
The following is an example of a structure in which a is suspended.

As shown in FIG. 2, the electrode b has a rod-shaped copper rod 10 as a core material, and has a hook 11 integrally protruding from the upper end thereof to be suspended from the bus bar 3.
0 is coated with an outer skin layer 12.

The outer skin layer 12 is formed of carbon fiber and synthetic resin, and the carbon fiber is made by firing acrylic fiber, for example, and the carbon fiber is impregnated with epoxy resin, phenolic resin, or unsaturated polyester resin. It is preferable to cure the outer skin layer 12 with high strength and high elastic modulus.

The method for constructing the outer skin layer 12 includes forming the outer skin layer 12 in advance by impregnating carbon fiber with a synthetic resin and hardening it, inserting the copper rod 10 into the outer skin layer 12, and sealing the opening with the same material. There is a method in which carbon fibers are arranged or coated on the outer periphery of the copper rod 10 and impregnated with a synthetic resin and cured, but any of these methods may be used.

The above carbon fibers are arranged in one direction, woven fabrics,
Any composition such as a knitted fabric or a randomly oriented matte may be used, and a composition in which glass fibers or synthetic fibers are interwoven is also optional.

The hook 11 is made of a conductive material such as a copper wire, and the hook 11 may also be coated with the outer skin layer 12.

The electrode b is suspended from the bus bar 3, and a cathode is applied to the hook 11, or if the support frame 2, bus bar 3, and column 1 are made of conductive material, the cathode is applied through them. applied.

FIG. 3 shows a modification of the electrode b, which has a structure in which a copper plate 10' is used as the core material and is covered with an outer skin layer 12.

FIG. 4 further shows a modification of the electrode b, in which a rectangular copper rod 10'' is used as the core rod, and its upper end is bent to integrally form a hook 11'.
The structure is such that the copper rod 10'' and the hook 11' are coated with an outer skin layer 12.

Next, FIG. 5 shows a case in which the electrode support frame a is constructed of the conductive member of the present invention, in which all or part of the support column 1, frame rod 2, and bus bar 3 are formed of copper, iron, aluminum, etc. It has a structure covered with the above-mentioned outer skin layer 12.

It should be noted that the conductive member of the present invention is not necessarily applied to all of the electrode b, support 1, frame rod 2, and bus bar 3, but may be applied to all or part of them. That is enough.

Since the present invention is constructed as described above, when used as an electrode, the outer skin layer has superior workability compared to conventional titanium electrodes, and electrodes of various shapes depending on the application can be obtained and can be manufactured at low cost. Moreover, it is reinforced with carbon fiber and synthetic resin to prevent damage during handling or exposure of the core material such as copper material.

In addition, when used as an electrode support frame, it also serves as a conductive member that conducts electricity to the electrode, and its workability and
It has high strength, improves manufacturing and durability, and can improve practicality.

Thus, the intended purpose can be achieved.
