Problems solved by technology

[0002] The terminals of low-voltage electrical equipment such as traditional AC contactors mostly use screws and arched gaskets to fix the connecting wires. Due to the poor shock resistance of screw fixing, they are easy to loosen, and the screws and gaskets are easy to fall off when connecting. falling, prone to electrical accidents
In order to prevent the screws from falling and loosening, there are currently connecting terminals that use plug-in connection wires, and there are also guide grooves on the insulating parts of the terminals and springs installed on the conductive sheets to prevent the screws from falling. The spring makes the structure of the conductive sheet particularly complicated, and also increases the manufacturing cost. For the plug-in connection terminal of the wire, the plug-in piece must be fixed on the terminal of the wire before connecting, which is very inconvenient to install.
[0003] Traditional low-voltage electrical appliances are provided with accommodating grooves in the insulating shell, and terminal terminals are arranged in the accommodating grooves. This structure integrates the accommodating grooves for setting the connecting terminals and the housing, and only needs one mold for injection molding. It has the advantage of a relatively simplified structure, but there are also some disadvantages: for example, when the terminal is installed in the accommodating groove, and when it needs to be replaced and maintained, the process is relatively cumbersome
