Current plug-connection module

Abstract

The invention discloses a current plug-connection module which is simple in structure and economical and reliable. The current plug-connection module comprises a male end module, a female end module and locking structures used for locking the male end module and the female end module. The male end module comprises a conductive metal connecting piece, an insulating base, a male end wiring structure and a male end signal plug-connection piece, and the female end module comprises a conductive metal connecting piece matching piece, an insulating piece, a female end wiring structure and a female end signal plug-connection piece matched with the male end signal plug-connection piece. Strong current signals and weak current signals are integrated in the same plug-connection module, only one locking structure needs to be fixed and released in plugging and unplugging, operation is convenient, efficiency is improved, space in an equipment cabinet is saved, cost is lowered, and the current plug-connection module is especially suitable for equipment like a switch cabinet where a plug-connection module needs to be plugged and unplugged frequently.

Description

technical field [0001] The invention relates to a current plug-in module. Background technique [0002] In various switch cabinets and power distribution cabinets, the general board adopts a drawer design, and the electrical components of the incoming and outgoing circuit are installed in the drawer, and the electrical components of each drawer are connected to the busbar of the cabinet through a plug-in module. High reliability, safety and interchangeability. With the vigorous development of intelligent power distribution technology, more and more switch cabinets are designed with intelligent components or intelligent modules. They need various interfaces to communicate with the outside, and the essence of communication is various For weak current signal transmission, these signals and strong current need to be connected to the outside through plug-in modules, but because strong current is characterized by high voltage, high current, and low frequency, while weak current s...

Problems solved by technology

With the vigorous development of intelligent power distribution technology, more and more switch cabinets are designed with intelligent components or intelligent modules. They need various interfaces to communicate with the outside, and the essence of communication is various For weak current signal transmission, these signals and strong current need to be connected to the outside through plug-in modules, but because strong current is characterized by high voltage, high current, and low frequency, while weak current signals are characterized by low voltage, low current, and high frequency. The properties of the two are very different, and the existing corresponding plug-in modules are difficult to use each other, and can only be electrically connected to the outside through their respective plug-in modules, especially in drawer-type cabinets, such connections need to be plugged frequently , many plug-in modules installed in the cabinet not only occupy limited space but also increase the failure rate due to too many components, which greatly reduces its reliability
