A micro quick connector based on nanofoil

Abstract

The invention provides a Nanofoil-based miniature quick connector. The Nanofoil-based miniature quick connector comprises a first base layer and a second base layer below the first base layer; the first base layer and the second base layer are fixedly connected; a first copper wiring layer is arranged on the upper surface of the first base layer; a second copper wiring layer is arranged on the upper surface of the second base layer; a third copper wiring layer is arranged on the lower surface of the second base layer; a cavity is formed in the middle of the first base layer; the cavity is located below the first copper wiring layer; an insulating layer is arranged in the cavity; a Nanofoil nano alloy foil sheet is arranged in the middle of the insulating layer; the Nanofoil nano alloy foilsheet is fixedly connected with the third copper wiring layer through a probe; and a through hole for allowing the probe to penetrate through is formed in the second copper wiring layer. The miniature quick connector is simple in structure, low in cost and high in controllability, can be replaced and integrated easily, and has the function of an industrial fast connector; meanwhile, the problem that an industrial connector cannot be integrated is also solved; and the miniature quick connector has high working characteristics for fault branch bypass circuits and switching in actual operation of the electrical equipment.

Description

technical field [0001] The present invention relates to the technical field of electrical engineering relay protection, in particular to a Nanofoil-based miniature quick connector, based on a printed circuit board (PCB) as the main material, integrating the functions of a controllable switching device and a line connector. It can be used for bypassing faulty circuits and switching between lines in power electronic devices. Background technique [0002] In recent years, although the reliability of power conversion devices has been continuously improved, power electronic components and their control circuits are still the most concentrated part of the failure rate, which can account for 93% of the total failure rate. For common faults of power installations, the protection method generally adopted is to isolate the faulty unit or branch circuit, and load the backup branch circuit or backup system to the load, so as to avoid shutdown or derating of the power conversion system. ...

AI Technical Summary

Problems solved by technology

The existing technology usually uses controllable power electronic devices to switch or bypass branches, but due to the additional power devices, it also needs to increase the control signal and its units, which undoubtedly reduces the overall reliability of the system. Once the control signal If the device is lost or the device is damaged, the switching will not be completed, and the loss caused by this is serious
