Abstract: A light screen of fiber optic connectors. The light screen of fiber optic connectors comprises a metal framework, a first metal spring tab and a second metal spring tab integrally formed inside the metal framework and distributed oppositely, and the end of the first metal spring tab and the end of the second metal spring tab are staggered, forming a spring tab opening-closing structure for shielding light. This new type of light screen is made of sheet metal, which has a certain strength, convenient for automatic assembly in late stage, and the first metal spring tab and the second metal spring tab of the light screen have excellent recovery capability, convenient to use, and the lifetime is longer. In addition, this new model has simple structure, very simple production technique and convenient assembly, so that this new model has very strong marketability.

Abstract: A locking device for securing an edge card to an electrical connector comprises a U-shaped locking portion and a pair of second locking portions formed at either end of the electrical connector. The first locking portion includes a locking body and two clips perpendicularly extending from the locking body. A connecting portion between the locking body and corresponding clip forms a pair of ribs defining a receiving space therebetween. Each clip includes two resilient arms having two outwardly projecting barbs at a free end thereof. The second locking portions each comprises a U-shaped guiding channel extending upward from a top face of the electrical connector, and a pair of holes being defined on opposite sides of the connector housing below the guiding channel. The resilient arms are pressed oppositely so that they can be downwardly inserted into the guiding channel. Two upper corners of the edge card are securely received within the receiving space of the first locking portion.
