On-board miniature optical fiber connector

Abstract

The invention discloses an on-board miniature optical fiber connector, which comprises an adapter, wherein the interior of the adapter is a cavity, an optical fiber, a clamp, a flange and a contact pin are arranged on one side of the adapter, the optical fiber, the flange and the contact pin are fixedly connected into a whole, a containing cavity is formed in the clamp, a first locking structure is arranged outside the clamp, locking and fixing between the clamp and the adapter are achieved by pushing the flange, the other side of the adapter is also provided with an optical fiber, a flange and a contact pin which are fixedly connected into a whole, an elastic reset piece and a pushing piece, the elastic reset piece is sleeved outside the optical fiber between the pushing piece and the flange, a second locking structure is arranged outside the pushing piece, the pushing piece and the adapter are locked and fixed by pushing the flange, the flange main body is of a polygonal structure, and a polygonal cavity part matched with the flange main body is arranged in the adapter. According to the invention, the connector is small and compact in structure, butt joint can be carried out at a fixed angle, energy loss caused by angle deviation due to rotation is avoided, and the using effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, in particular to a miniature optical fiber connector on a board. Background technique [0002] In the current technology in the field of optical fiber communication, standard optical fiber connectors, such as LC-type connectors specified in IEC 61754-20, are mostly used in optical fiber interconnection scenarios in narrow spaces such as on the motherboard. This type of standard connector has mature technology and is widely used, but it is not specially designed for onboard or small use environments. It has many problems such as large size of the connector, many installation and disassembly steps, inconvenient operation, and high space requirements. [0003] In order to solve the above technical problems, the U.S. Patent Publication No. US6616343B2 discloses The optical fiber positioning member, which is small in size and can be used for on-board connection, but it uses a shrap...

Problems solved by technology

This type of standard connector has mature technology and is widely used, but it is not specially designed for board-mounted or small use environments. It has many problems such as large connector size, many installation and disassembly steps, inconvenient operation, and high space requirements.

[0003] In order to solve the above technical problems, the U.S. Patent Publication No. US6616343B2 discloses The optical fiber positioning member, which is small in size and can be used for on-board connection, but it uses a shrapnel clamping mechanism, which leads to poor reliability of the connector due to unstable elastic force. It is not high, and at the same time lacks the angle holding structure, and does not support angle grinding for circular ferrules, which has great limitations
