Problems solved by technology

The problem with the existing transfer connector is that although the glue filling seal ensures that the gas does not leak, the contact loses its floating function, and the optical fiber docking accuracy is micron or even sub-micron precision. The current housing processing and The assembly accuracy cannot meet the requirements at all, which will inevitably lead to the problem of large insertion loss of the connector when the transfer connector is mated with the mating connector

Embodiment Construction

[0019] Examples of sealed fiber optic connectors are Figure 2~6 As shown: it includes optical contacts 17 and a housing. There are multiple optical contacts and are located at both ends of the housing. The optical contacts at each end are divided into four optical contact groups arranged at intervals along the up and down direction. Each optical contact Each component group includes 12 optical contacts. The optical contacts in each optical contact group are connected together through connectors to form an MT pin 7. The MT pin on the left and the MT pin on the right The pins are set in one-to-one correspondence, and the corresponding two MT pins are connected by optical fibers. The housing includes an outer housing 4 and an inner housing. The outer housing 4 is provided with a connecting flange 2 and a connecting structure for connecting with an adapter connector. The connecting structure includes external threads 1 and internal threads 6 arranged at both ends of the outer hou...

Abstract

The invention relates to a sealed optical fiber connector comprising optical contact elements and a housing. Mounting holes extending from the left to right are formed in the housing; and the optical contact elements are assembled into the mounting holes in a guiding moving mode along the left-right direction. A left blocking structure for limiting the optical contact elements to a limit for left movement is arranged on the housing. An optical fiber penetrates the mounting holes and includes a sealing segment cooperating with the mounting holes by a sealing structure and a bendable segment that is located at the left side of the sealing segment and is connected with the optical contact elements and can be bent under the acting force towards the right. Besides, a right blocking structure that is used for limiting the optical contact elements to a limit for right movement is arranged on the housing. The provided sealed optical fiber connector not only can be sealed but also can float axially.

Description

technical field [0001] The invention relates to a sealed optical fiber connector. Background technique [0002] When it is necessary to introduce an optical signal into a sealed box or to extract an optical signal from the box, an adapter connector needs to be provided on the box to ensure the sealed environment of the box. Existing transfer connectors such as figure 1 Shown: includes the housing 2, the housing 2 is provided with a mounting hole extending in the left and right direction, the optical contact 1 is arranged in the mounting hole, and the optical contact 1 and the mounting hole are sealed with glue 3. When in use, Seal the housing on the box body. The problem with the existing transfer connector is that although the glue filling seal ensures that the gas does not leak, the contact loses its floating function, and the optical fiber docking accuracy is micron or even sub-micron precision. The current housing processing and The assembly accuracy is not up to the ...
