Abstract: An adaptor with a built-in shutter member for optical connector including a body, a shutter, and an elastic member is provided. The body has a receiving space. The shutter is movably assembled to the body to shield or expose the receiving space. An optical connector is suited for pushing away the shutter to enter the receiving space to be connected to the body. The shutter has a step structure such that a gap is maintained between the shutter and the optical connector. The elastic member is disposed in the body and located on a moving path of the shutter. The shutter deforms the elastic member when the optical connector pushes away the shutter, and the elastic member drives the shutter to be restored when the optical connector leaves the receiving space.

Abstract: An optical fiber cassette with corresponding rail structures includes a plurality of rail structures and an optical fiber cassette. Each rail structure includes a front flexible buckling arm and a rear buckling hook. The front flexible buckling arm includes a first suspended arm reflexed from a front portion of the rail structure and a stopping block formed on an end portion of the first suspended arm. The optical fiber cassette is located between the corresponding rail structures. The optical fiber cassette includes a front engaging block corresponding to the front flexible buckling arm and a rear buckling arm corresponding to the rear buckling hook. The rear flexible buckling arm includes a second suspended arm reflexed from a rear portion of the optical fiber cassette and an engaging hook formed on an end portion of the second suspended arm.

Abstract: An optical adapter includes a base body, a shutter member, and a supporting base. The shutter member is pivotally connected at an insertion opening of the base body. The supporting base is assembled on a bottom portion of the base body. A surface of the supporting base has an abutting piece inside the base body. One of two ends of the abutting piece includes a fixing portion fixed on the supporting base, and the other end of the abutting piece includes an abutting portion obliquely extending toward the shutter member to abut against a back surface of the shutter member. Therefore, the supporting base can be assembled on the bottom of the base body conveniently. Furthermore, when the abutting piece is pushed and compressed by the shutter member, the abutting piece is not prone to have excessive deformation, prevent the abutting piece from being deformed or damaged easily.

Abstract: A rack-mount chassis includes a rear casing, a door plate, a first pivot assembly, and a second pivot assembly. The rear casing has an opening. The door plate is configured to shield the opening. The first pivot assembly includes a first bearing portion and a first shaft portion. The first bearing portion has a first shaft hole and a first passage. The first passage extends from the first shaft hole to an outer edge of the first bearing portion. The first shaft portion has a first shaft body. The first shaft body is moved into the first shaft hole through the first passage. The second pivot assembly includes a second bearing portion and a second shaft portion. The second bearing portion has a second shaft hole. The second shaft portion has a second shaft body. The second shaft body is located in the second shaft hole.

Abstract: A rail structure for optical fiber cassette is adapted to be assembled on a board member of a fiber box. The first engaging structure and the second engaging structure at two ends of the rail body are movably engaged with the first buckling structure and the second buckling structure. Hence, the user may detach one of the rail structures from the board member, so that the distance between the rest two of the rail structures goes wider, and the user can assemble another optical fiber cassette between the two rail structures, and the type and the size of the optical fiber cassette may be different from the detached one. Hence, the rail structure has wide applicability to allow the user to change the optical fiber cassette with different types and specifications conveniently and quickly.

Abstract: A waterproof bushing connector assembly has a waterproof bushing receptacle connector having a receptacle housing assembly, a receptacle bushing module and an optical receptacle connector, and a waterproof bushing plug connector engaged detachably with the waterproof bushing receptacle connector and having a plug housing assembly, a plug bushing module, an optical plug connector and a rear mounting lid. The bushing designs allow different optical receptacle connectors to be replaced on an electrical device easily and conveniently.
