Abstract

The invention provides an LRM (Line Replaceable Module) module locking and plugging device, which settles the problems of complex structure, poor stability and reliability and inconvenient locking and plugging operations in traditional products. The device is composed of a fork lever component fixed on a frame and a plugging component fixed on an LRM module, wherein the plugging component is designed in such a manner that double concave wheels are in elastic tight fit with a four-link movement mechanism, pressure is applied to a pin in the fork lever by pulling a push rod in order to lock or plug out the LRM module. The LRM module locking and plugging device realizes the onsite hand plugging and locking function for the first time on the premise of conforming to the ARINC650 standard, the entire mechanism achieves the automatic adjustment for tightening distance, eliminates processing and assembling errors and has predetermined pretightening force, thereby guaranteeing the reliable tightening of equipment under various harsh vibratory conditions.

Description

technical field [0001] The invention relates to a module locking and plugging device, in particular to an LRM module locking and plugging device based on the ARINC650 standard. Background technique [0002] With the rapid development of avionics technology, the application fields of airborne electronic equipment continue to expand, the application environment is also more complex, and the requirements for structural interconnection technology continue to increase. Especially in recent years, the degree of integration of avionics systems has become higher and higher, and the structural form of electronic equipment has undergone major changes, and new requirements have been put forward for structural interconnection technology. In order to meet the structural interconnection requirements of airborne electronic equipment, various standards have also been established. [0003] It is applied to the integrated rack of airborne electronic equipment and the locking and unplugging o...
