Abstract

A dustproof optical backboard connector comprises a backboard connector and a daughter board connector, and the backboard connector and the daughter board connector are connected in a mutually inserted manner. The backboard connector comprises a seat shell and a seat dustproof door assembly, and the seat dustproof door assembly is arranged in the opening end of the seat shell. The daughter board connector comprises a head shell and a head dustproof door assembly, the head dustproof door assembly is arranged in the opening end of the head shell, and the head shell is inserted into the seat shell. The dustproof door assembly comprises a first dustproof door, a first reset assembly and a first pushing assembly, and the head dustproof door assembly comprises a second dustproof door, a second reset assembly and a second pushing assembly. According to the present invention, the first dustproof door blocks the opening of the backboard connector, and the second dustproof door blocks the opening of the daughter board connector, so that the connection sealing performance of the dustproof door and the connector is effectively improved, the fit clearance is eliminated, and external dust is prevented from entering.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a dust-proof optical backplane connector. Background technique [0002] With the development of optical communication requirements, the presence of fan cooling components in the cabinet will drive the disturbance of dust in the cabinet, resulting in the contamination of the butt end of the optical fiber contact and affecting its transmission performance. Therefore, the use of optical backplane connectors with dust-proof doors for signal transmission is increasing. [0003] However, due to the size and structural limitations of common dust-proof optical backplane connectors, most of them can adopt the two-half type dust-proof door structure with an outer door or an inner door. When opening the door, whether it is an inward-opening type or an outward-opening type, the dust attached to the door surface will fall into the butt end of the optical fiber contact from the opening whe...
