A sub-board plug assembly and an inter-board connection assembly

Abstract

The invention provides a sub-board plug assembly and an inter-board connection assembly, wherein the sub-board plug assembly includes a sub-board fixing frame, a sub-board plug, and a locking assembly. The locking assembly includes a wedge-shaped locking structure and a plug-in locking structure. The locking structure is installed on the sub-board fixing frame, including the locking rod, the driving wedge, the extrusion wedge and the extrusion driving structure. The driving wedge and the extrusion wedge are both mounted on the locking rod, and the extrusion drive The structure can drive the extrusion wedge and the driving wedge to approach and squeeze each other; the plug-in locking structure includes a threaded locking piece arranged on the plug of the sub-board; the inner end of the locking rod can be locked with the threaded locking piece , the rotation of the locking rod drives the threaded locking member to rotate and can be tightened with the threaded locking structure of the backplane socket, thereby realizing the locking between the daughterboard plug and the backplane socket; while the daughterboard plug assembly and the chassis are squeezed tightly The plug assembly of the daughter board is locked with the socket assembly of the backplane, thereby improving the reliability between the plug assembly of the daughter board and the socket assembly of the backplane.

Description

technical field [0001] The invention relates to the technical field of airborne equipment structural accessories, in particular to a sub-board plug assembly and an inter-board connection assembly. Background technique [0002] The sub-board plug assembly and the backplane socket assembly are installed in the chassis, and the cooperation reliability of the sub-board plug assembly and the backplane socket assembly is related to the reliability of the entire chassis. At present, the sub-board plug assembly and the backplane socket assembly in the chassis are guided by the chassis to realize blind mating and docking, and then the locking bar is used to fix the sub-board plug assembly. A printed board card different direction wedge locking mechanism, the wedge locking mechanism realizes the fixing of the sub-board plug assembly and the chassis through the locking strip composed of the locking body, the screw rod, the through-hole locking block and the threaded locking block, The...

Problems solved by technology

At present, the sub-board plug assembly and the backplane socket assembly in the chassis are guided by the chassis to realize blind mating and docking, and then the locking bar is used to fix the sub-board plug assembly. A printed board card different direction wedge locking mechanism, the wedge locking mechanism realizes the fixing of the sub-board plug assembly and the chassis through the locking strip composed of the locking body, the screw rod, the through-hole locking block and the threaded locking block, The backplane socket assembly and the sub-board plug assembly are indirectly fixed, that is, the chassis and the sub-board plug assembly are fixed, and the chassis and the backplane socket assembly are fixed. The reliability of the sub-board has a certain influence, and after the sub-board plug and the backplane socket are mated in place, the sub-board plug assembly has no mechanical limit in the direction of pulling out, and it is completely guaranteed by the friction of the locking strip, resulting in the sub-board plug. The locking between the component and the backplane socket component is not reliable, and there are certain potential safety hazards
