JPH07282869A - Quick joint device for electrode bus bar connection in electric plating line - Google Patents

Abstract

PURPOSE:To shorten the line stop time by pinching and connecting a power feed side fixed bus bar feeding electricity to an electrode plate and a plating cell side electrode plate bus bar from both sides with a hinge-like quick joint. CONSTITUTION:A plating cell side electrode plate bus bar 2 is suspended together with a plating cell at the terminal section of an electrode feed fixed bus bar 1 erected from below, and the bus bars 1, 2 are alternately coupled. A quick joint 5 is mounted on a quick joint mount 6 installed on the bus bar 1 in the electrically insulated state, and it has three hinge bus bar pinching mobile arms 7. When the arms 7 are closed and three fixing bolts 8 fitted on opposite side to the arms 7 are fastened and fixed to arm tip bolt holes, the bus bars 1, 2 are thoroughly pinched by the joint 5, and the connection of the bus bars 1, 2 is completed. The work is completed by only three bolts, and the work load and working time can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode bus bar connection in a continuous electroplating line for connecting a fixed bus bar on the power supply side and an electrode plate bus bar on the plating cell side, which is necessary for supplying a current to a plating cell electrode. For quick joint device.

[0002]

2. Description of the Related Art A fixed bus bar on the side of a current supply that sends electricity to a plating cell electrode plate that is continuous in several stages of an electroplating line, and a bus bar on the electrode plate side of a plating cell are connected to each other by passing a large current, so that electrical contact resistance is increased. In order to make it as small as possible, it is necessary to stick the bus bars together. For this reason, a fastening method using a plurality of (9 as an example) bolts is used to connect the bus bars.

Therefore, according to this fastening method, when the plating cell is removed at the time of checking the plating cell or replacing the electrode plate,
It was necessary to remove these bolts without fail, and the reverse procedure was also required when installing the plating cell at the time of restoration, and these operations required a lot of labor and time.

In addition, as a reference example, the actual construction of Shokai 55-1277.
There is No. 8.

[0005]

Conventionally, since the plating cell inspection and the electrode plate replacement work are performed within the limited production line down time, the time and effort required for opening and reconnecting the bus bar fastening bolts are naturally high. It is within the range of the work cost and the required downtime, and it has been a subject to reduce the time and effort which do not contribute to the production of these materials.

[0006]

SUMMARY OF THE INVENTION The present invention provides multiple (eg, 9
Instead of tightening with the bolts), the busbars are firmly pinched from both sides with a hinge-like quick joint, and they are only fixed with three bolts to obtain sufficient adhesion between the busbars. This is a quick joint device for connecting electrode busbars in an electroplating line that enables easy connection / opening work.

[0007]

[Operation] By reducing the bolt fastening amount required for connecting / disconnecting the bus bars to 1/3, both the working amount and the working time can be reduced to 1/3 or less. Therefore, it is possible to reduce the work cost and work time when the line production is stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment device shown in the drawings.

FIGS. 3A and 3B are views showing a conventional bus bar connection mode by bolt fastening. The power supply side fixed side bus bar 1 rising from below and the plating cell electrode plate side suspended along with the plating cell. Insert the fastening bolts as many as the number of holes into the bolt holes 3 formed in the bus bar 2 and
It requires a lot of trouble and time because they are connected by tightening them.

FIG. 1A is a perspective view showing a bus bar fitting connection of an embodiment according to the present invention, in which an electrode supply fixing bus bar 1. At the end of the, the plating cell side electrode plate side bus bar 2. Is suspended along with the plating cell. At this time, similarly to the conventional bolt fastening method, the bus bars are alternately fitted into the fixed side bus bars.

FIG. 1B is a perspective view illustrating a state in which bus bars are connected by a quick joint. Is a quick joint stand 6. installed on the fixed-side bus bar 1. 7. It is mounted in an electrically insulated state on the hinged hinged bus bar and movable arm 7. Has three. The fixing bolt which is attached to the opposite arm side to the arm tip bolt hole (not shown) by closing the sandwiched movable arm 7. By tightening and fixing only 3
The bus bar is fully sandwiched by the quick joint 5,
The connection between the bus bars is completed.

2 is a plan view illustrating the details of the quick joint, in which the movable arm 7. One of them has a push bolt 9. There are three push bolts, and the total of the three arms is nine push bolts, so that the sandwiching force at the conventional bolt fastening position can be adjusted.

The push bolt 9. Need only be set once at the initial connection with the quick joint 5, and there is no need to make adjustments during normal bus bar connection / opening.

[0014]

As described above, in contrast to the conventional bolt connection that requires time and labor, the quick joint requires only the bolts (three in the embodiment) for tightening the arm, and the amount of work Since the time can be reduced to about 1/3 or less, it is possible to reduce the line down time and the work cost by reducing the labor and time that do not contribute to the production.
