Problems solved by technology

) This structure is easy to cause the interference of strong current on the control current
[0003] First of all, the base of the plug-in module has both the terminal for the main contact that passes the large current and the terminal for the weak current of the control loop coil. The distance between these two terminals is very close, and the terminal wiring distance is also very close. Such a structure There is a hidden danger of current interference

Abstract

The invention discloses a strong and weak electricity isolation plugging device which comprises a base body and a plugging module. An integrated circuit board, an embedding groove and a wiring terminal are arranged in the base body, an electrical connection sheet is arranged on the side wall of the embedding groove, a pin hole is formed in the bottom wall of the embedding groove, and the pin hole penetrates through the end surface of the integrated circuit board; the wiring terminal is located on the outer side of the embedding groove, wiring ports are formed in the side portion of the base body, and the wiring ports correspond to the wiring terminal; the wiring terminal is electrically connected with the electric connecting sheet; and the bottom end of the plugging module is provided with a pin, the side part of the plugging module is provided with a conductive sheet, the plugging module is used for being embedded in the embedding groove so that the pin is inserted in the pin hole, and the conductive sheet is electrically connected with the electrical connecting sheet. According to the strong and weak electricity isolation plugging device, the strong electricity with a load and the weak electricity with a control loop can pass through different lines respectively and are isolated from each other independently.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a strong and weak current isolation plugging device. Background technique [0002] At present, the existing plug-in module plug-in structure is for plugging and unplugging a rated current lower than 5A, and the plug-in pins are at the bottom of the plug-in module plug. The pins are small metal copper sheets, not only through The current is limited, and the pins are easy to break. In addition, the plug-in module is a structure that integrates strong and weak electricity (strong electricity refers to voltage in addition to current, strong current refers to AC and DC current above 10A, and strong voltage refers to AC and DC voltage above 110V. Substitute current, also refers to voltage, weak current refers to the rated current that works normally on the PCB board, and weak voltage refers to AC and DC voltage in the range of 1 ~ 250V.) This structure is easy to cause st...
