Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber connector. Background Art

[0002] In fiber-optic communications, fiber optic connectors are often used to connect to fiber optic adapters on distribution frames to achieve optical fiber transmission. Fiber optic connectors generally have a fiber optic connector head that mates with the fiber optic adapter. The tail end of the fiber optic connector head is connected to a tail sleeve. To protect the fiber optic connector head and facilitate insertion and removal, the fiber optic connector head is generally provided with a housing. When inserting and removing the fiber optic connector, you need to pinch the housing to do so.

[0003] However, with the advancement of fiber optic technology, the density of fiber optic adapters has increased. When fiber optic adapters are densely connected to fiber optic connectors, the fiber optic connectors are often arranged closely together, resulting in a small gap between the housings of adjacent fiber optic connectors. Due to the limited space, it is difficult to insert fingers into the gaps between the fiber optic connector housings, making extraction more difficult. Furthermore, if you try to remove the fiber optic connector by pulling on the tail sleeve attached to the rear end of the fiber optic connector, because the tail sleeve is not fixed to the housing, forcibly pulling on the tail sleeve will not only fail to remove it, but can also damage the fiber optic connector. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an optical fiber connector, which can make the optical fiber connector more convenient to be pulled out.

[0005] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:

When the second housing is pulled out, the pulling force can be transmitted to the first housing to achieve the removal of the optical fiber connector;

[0018] 2) When a pull rod is provided on the second housing, the optical fiber connector can be pulled out by pulling the pull rod extending from the second housing, transferring the force point from the first housing to the pull rod of the second housing away from the first housing, thus avoiding the problem of difficult insertion of fingers due to crowded space between the first housings and making pulling out more convenient;

[0019] 3) When the second housing is connected to the tail sleeve, the optical fiber connector can be removed by pulling the tail sleeve, transferring the force point from the first housing to the tail sleeve, avoiding the problem of crowded space between the first housings making it difficult to insert fingers, and making pulling and removing more convenient.
