Fail Analysis of Screw Terminal of Fixed Switch and Socket |
| |
Abstract: | Terminal is an important part in the fixed switch and socket, and it is closely related to the convenience to connect cable and the reliability to apply, so it is the key point that the customer, especially the electrician, to choose the product. According to failure phenomenon, this paper analyzes and calculates a few universal screw terminal in the market, and simply states that the reason of temperature rising and contact point melting is related to connecting instability of panel terminal. It can be a reference to choose the terminal in the design of the industry. |
