Optical fiber connector assembly and optical fiber connector, optical fiber connector housing assembly

Abstract

The invention relates to an optical fiber connector assembly, an optical fiber connector and an optical fiber connector shell assembly. The optical fiber connector assembly comprises a plug connector and a socket connector, wherein the socket connector comprises a connector shell assembly and a socket inner core arranged in the connector shell assembly, the connector shell assembly comprises a connector shell and a limiting plate, a slot with an opening facing rearwards is formed in the rear end of the connector shell, the limiting plate is fixed at the rear end of the connector shell and matched with the slot to form an inner cavity which is used for allowing the socket inner core to float in the left-right direction and up-down direction inside the inner cavity, so that after a socket is fixed on a printed board, the socket inner core can float in the inner cavity formed by the limiting plate and the slot; and the shell and the inner core of the socket connector form an integral part, so that the problems such as inconvenience in management of components and complexity in assembly when in use caused by independence of the connector shell and the socket inner core can be solved.

Description

technical field [0001] The invention relates to an optical fiber connector assembly, an optical fiber connector, and an optical fiber connector shell assembly. Background technique [0002] The inter-board optical fiber connector is mainly used to realize the transmission and connection of optical signals between the daughter board and the motherboard. Since the inter-board optical fiber connector is connected and separated at a position that cannot be seen by the human eye inside the equipment (that is, blind insertion), this optical fiber connector needs to design a floating structure between its plug and socket to compensate for insertion. time positioning error. [0003] For example, the Chinese patent application with application publication number CN 103308989 A and application publication date of 2013.09.18 discloses an inter-board optical fiber connector, which is a receptacle connector used in printed boards, including a first housing body, the second housing, and...

[0003] For example, the Chinese patent application with application publication number CN 103308989 A and application publication date of 2013.09.18 discloses an inter-board optical fiber connector, which is a receptacle connector used in printed boards, including a first housing body, the second housing, and a holder for press-fitting the fiber ferrule in the first housing. The first housing is provided with a positioning hole for the fiber ferrule to protrude forward, and the fiber ferrule is inserted into the After being pressed and fixed by the retainer in the positioning hole on the first shell, the inner core of the socket is formed. The rear end of the second shell is provided with a slot facing the rear. The shape of the slot is the same as that of the first shell. The body has the same shape and the size of the slot is slightly larger than the outer dimension of the first shell. When in use, first install the inner core of the socket in the slot of the second shell, and then screw it from the rear end of the second shell. The second housing is fixed on the printed board, and the inner core of the socket passes through the avoidance hole on the printed board and protrudes backward. The end-face stop fit restricts the inner core of the socket in the slot at the rear end of the socket so that it can float in the second housing. The second housing and the inner core of this optical fiber connector are independent of each other, which is convenient for transportation and parts. Management is inconvenient, and when in use, these two parts need to be reassembled before they can be assembled on the printed board, and the assembly process is cumbersome
