How to connect the hook and the copper bar?

How to connect the hook and the copper bar is the best? Here are a few ways to connect, let's analyze the advantages and disadvantages of different connection methods. The connection methods are as shown in the figure below.

Hook

Advantages and disadvantages of different connection methods between hook and copper:

1 The connection between the hook and the copper bar is curved, and the joint has strong elasticity after installation, and the contact area is large, so the contact performance is good.

2 The hook is in close contact with the copper bar, and the hook will be pressed down when the heavy workpiece is mounted, and the contact performance is good.

3 The contact surface of the hook and the copper bar is only at the top plane. When the workpiece is hung, the hanger is slightly inclined, and the contact surface of the hook and the copper bar may only be in the upper right corner.

4 The contact point between the hook and the copper bar is too shallow to be stuck, and sometimes it will “jump up” on its own, just resting on the copper bar.

5 The contact surface of the hook and the copper bar is only at the two corners of the square copper bar, and it is also highly likely to cause tilting.

6 After the hook is pressed, it will fall down. The hook of the original clamped copper bar will be loosened, which will affect the electrical conductivity.

7 The hook is in contact with the square copper bar only at the three corners, the contact point is too small, and the hook may change direction. At this time, it is possible that the original vertical hanging plate is inclined, and the lower end of the plated part is away. The anode is too close and burnt.

8 hooks are too large, hanging on small copper bars, the activity is large, affecting the contact performance.

9 The hook is only stuck in the throat. When the workpiece is mounted on the hanger, when it sinks, the disadvantage is the same.

10 Hooks have only two contact points for the triangle and the copper bar. Generally, the hook for the lightweight workpiece using the hanger is not suitable for this type; especially when moving the cathode or the solution is working under the agitation of compressed air.

From the above 10 types of hook and copper connection analysis, the two and two are most suitable, and the rest have different degrees of defects.
