The present invention was developed to improve these drawbacks, and its basic features are that a groove is formed on the bottom of the anode, a current-carrying body is fitted into the groove, and the anode is slid using the current-carrying body as a guide. That is. According to this configuration, since the anode slides using the current-carrying body as a guide, parallel and smooth sliding can be performed, and poor contact between the anode and the current-carrying body can be prevented. Further, since the current carrying body is fitted into the groove, the bottom and both side surfaces of the groove are in contact with the current carrying body, so that the contact between the anode and the current carrying body is improved. Furthermore, since the grooves are formed on the bottom surface of the anode, there is little wear around the grooves, and the above-mentioned contact properties are not impaired over time.
以下本考案の実施例を図面に基づいて説明す

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

を時間経過により損うことがない。 In Fig. 1, 10 is a plating tank, 11 is a seal roll, X is a steel plate to be plated, 1 is an anode, 2
is a current-carrying body. In this embodiment, a groove 4 having a rectangular cross section is formed in the width direction of the plating tank on the bottom surface of the anode 1, and a circular current carrying body 2 is fitted into the groove 4. With this configuration, the anode 1 slides parallelly and regularly using the current carrying body 2 as a guide. Therefore, no contact failure or the like occurs between the anode 1 and the current-carrying body 2, and no spark occurs. Further, the arrangement of the anodes 1 does not become zigzag. In addition, the current carrying body 2 is placed in the groove 4.
Since the anode 1 and the current carrying body 2 are fitted into the groove 4, the bottom and both side surfaces of the groove 4 come into contact with the current carrying body, so that the contact between the anode 1 and the current carrying body 2 is improved. Furthermore, since the grooves 4 are formed on the bottom surface of the anode 1, there is little wear around the grooves 4, and the above-mentioned contact properties are not impaired over time.

60A／ｄm2のメツキ条件で得たものである。 Even if the slide guide of the above embodiment is used, if the slide pitch of the anode is longer than 2 hours, phenomena such as welding will occur between the anode and the current-carrying body, and this will cause sparks to occur during the slide. The relationship between this welding phenomenon and operation time is shown in FIG. This graph shows ZnSO 4 :500g/, PH=4, current density
This was obtained under plating conditions of 60A/ dm2 .

金メツキ浴については復極現象による金属酸化物
の析出に起因している。 This welding phenomenon is caused by a decrease in the current-carrying area and a drop in contact pressure, and this reduction in the current-carrying area is caused by the formation of an oxide film in the gap between the anode and the current-carrying body, or by the formation of an anion complex. For alloy plating baths that form, this is due to the precipitation of metal oxides due to the depolarization phenomenon.

することが必要である。 In order to prevent welding between the anode and the current-carrying body, which can cause sparks when the slide pitch exceeds 2 hours, the structure of the guide mechanism is such that the anode and the current-carrying body are in contact with each other with high contact pressure and a high contact surface. It is necessary to create a structure that allows for

いる。 FIG. 3 shows an embodiment aimed at preventing such welding, in which a groove 4' having a triangular cross section is formed in the anode 1.
is formed in the width direction of the plating tank, and the current-carrying body 2' is fitted into this groove 4'. The current-carrying body 2' also has a protrusion 20 having a triangular cross section, and this protrusion 20 is fitted into the groove 4'. With such a configuration, the apex of the protrusion 20 and the groove 4' come into contact with each other under high pressure,
Furthermore, since the contact area is increased, it is possible to prevent the formation of oxide films in the gaps between the contact surfaces and the precipitation of metal oxides due to depolarization in alloy plating baths that form anion complexes. Therefore, it is also possible to suppress sparks caused by these causes. In this embodiment, a nozzle 5 is further provided near the contact portion of the current carrying body 2 of the anode 1, and a jet of plating liquid is applied from the nozzle 5 to the contact portion, thereby further preventing the depolarization phenomenon described above. There is.

により損うことがない等の効果がある。 As described above, in the anode-current carrying body structure of the present invention, a groove is provided on the bottom surface of the anode, into which the current carrying body is fitted, and the anode slides using the current carrying body as a guide, so that the anode slides smoothly. It is done in parallel. Therefore, poor contact between the anode and the current-carrying body can be prevented, and sparks generated between them can be prevented. Furthermore, since the slides are performed in parallel, the arrangement of the anodes is not disturbed. Furthermore, since the current-carrying body is fitted, the bottom and both side surfaces of the groove are in contact with the current-carrying body, thereby improving the contact between the anode and the current-carrying body. Furthermore, since the grooves are formed on the bottom surface of the anode, there is less wear around the grooves, and the above-mentioned contact properties are not impaired over time.
