[Field of Application in Industrial Materials] The present invention relates to an anode device in electroplating equipment. [Prior Art] In horizontal electroplating equipment, as shown in FIGS. 5 and 6, an anode is made up of an anode member 1' and a current-carrying bar 2' on which the anode member 1' is placed to form an anode. A device A is used, and the strip S running opposite the anode is plated by a plating current flowing through the current-carrying bar 2' and the anode member 1'. [Problems to be solved by the invention] In the above-described anode device, the anode member may be self-soluble or insoluble. For example, in the former case, the anode member may be chemically dissolved by the plating solution. As it gradually wears out, the contact area with the current-carrying bar decreases, or oxides are deposited on it, which obstructs the flow of current, resulting in increased voltage drop, heat generation, and melting damage to the anode and current-carrying bar. Furthermore, even insoluble anodes may melt due to contact resistance with the current-carrying bar. The present invention has been devised in view of such conventional problems, and is intended to provide an anode device having a structure that appropriately prevents melting and damage of the anode member and the current-carrying bar. [Means for solving the problem] As a result of various studies conducted by the present inventors on the contact area between the current-carrying bar and the anode member, it was found that physical properties specific to metals and chemical reactions between the contact member materials increase contact resistance and impair current conductivity. It turned out that he was deeply involved. As a result of further studies based on these facts, we decided to adopt a structure in which a member of the same quality as the contact part of one of the anode members and the current-carrying bar is fixed to the contact part of the other. It has been found that melting damage to members and current-carrying bars can be effectively suppressed. For this reason, in the present invention, a current-carrying member made of the same material as the other contact part is fixed to the contact part of one of the anode members and the current-carrying bar, so that the mutual contact parts of the anode member and the current-carrying bar are made of the same material. This is its basic feature. [Operation] As a result, the anode member and the current-carrying member, which are made of different materials, are tightly fixed together, and since the current-carrying member and the current-carrying bar are made of the same material and are in close contact with each other, there is no difference between each member. sufficient electrical conductivity is ensured,
In addition, chemical reactions between contact member materials are appropriately prevented. [Example] Hereinafter, an example of the present invention will be described based on the drawings. 1 to 3 show an embodiment of the present invention relating to an insoluble type anode device, in which 1 is an insoluble anode member, 2 is an energizing bar, and 3 is a support member that supports this energizing bar 2. . Further, 4 is the core material of the anode member, 5 is the running material, and 6 is the core material of the anode member.
is the electrolytic surface. At the contact portion of the anode member 1 with the current-carrying bar, current-carrying members 7, 7 made of the same material as the current-carrying bar 2 are tightly fixed with fixing bolts 8, and the anode member 1 It is placed on the energizing bars 2, 2 via the energizing bars 2, 2. In addition, when the above-mentioned energizing member 7 is bolted to the anode member body or the energizing bar body in this way,
The bolt 8 can be subjected to electric welding or the like to provide a structure that further improves adhesion. It goes without saying that the current-carrying member 7 can be made of the same material as the anode member and fixed to the current-carrying bar 2 side. FIG. 4 shows a cross section of the self-fusing type anode device of the present invention, and the fixing structure of the current-carrying member 7 is the same as that shown in FIGS. 1 to 3. In the above-described apparatus, the strip S is plated by the plating current flowing to the strip S via the current-carrying bar 2, the anode member 1, and the plating liquid. Since the different anode members 1 and the current-carrying member 7 are tightly fixed, and the current-carrying member 7 and the current-carrying bar 2 are made of the same material and in close contact with each other, the current conductivity between each member is sufficient. In addition, chemical reactions between contact member materials are appropriately prevented. The table below uses zinc or iron as the anode material,
This is a comparison of the occurrence of melting damage in the device of the present invention, which has a current-carrying member fixed as shown in the drawing, and the conventional device that does not have such a current-carrying member, and the plating conditions are as follows. It is.・Plating composition ZnSO 4・7H 2 O 200g/FeSO 4・7H 2 O 400g/PH 3 Temperature 50℃ ・Plating conditions Current density 50A/dm 2 Current 25000A

As described above, according to the present invention, the anode member and the current-carrying bar are provided with a current-carrying member made of the same material as the other contact part, so that the mutual contact parts of the anode member and the current-carrying bar are made of the same material. Since the anode member and the current-carrying bar are fixed together, the electrical conductivity between the anode member and the current-carrying bar is always ensured, which has the advantage of appropriately suppressing melting loss of these members.
