Current plug-in module

Abstract

The invention discloses a simple structure, economical and reliable current plug-in module, which includes a male terminal module, a female terminal module, and a locking structure for locking the male terminal module and the female terminal module. The male terminal module includes a conductive metal connector, an insulating The base, the male terminal wiring structure, and the male terminal signal connector; the female terminal module includes conductive metal connector fittings, insulators, female terminal wiring structure, and the female terminal signal connector that cooperates with the male terminal signal connector. Integrate strong and weak current signals into the same plug-in module, only need to fix and unlock a locking structure when plugging and unplugging, which is convenient to operate, improves efficiency, saves space in the cabinet, and reduces costs, especially suitable for applications that require Switch cabinets and other equipment that often plug in and out the plug-in modules.

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
