Multi-core optical fiber connector

Abstract

The invention discloses a multi-core optical fiber connector, which comprises an outer frame sleeve, a shell, a first spring, an insertion core, a base, a second spring, a stop dog, a jacket and a tail sheath, wherein the first spring, the insertion core, the base, the second spring and one end of the stop dog are installed in the shell; the outer frame sleeve is arranged on the periphery of the shell, a guide rod is arranged at the front end of the base, a guide hole corresponding to the guide rod is formed in the rear end of the insertion core, the guide rod is inserted into the guide hole,one end of the second spring abuts against the rear end of the base, the other end of the second spring abuts against the stop dog, and the front end of the jacket is installed at the rear end of thestop dog, and the tail sheath sleeves the rear end of the jacket; guide columns are arranged on the two sides of the shell, and the guide columns are sleeved with the first springs. The multi-core optical fiber connector can prevent poor product test caused by falling of the first spring when the outer frame sleeve and the shell are repeatedly plugged and unplugged, and the tensile and compressivecapacity and the use reliability of the multi-core optical fiber connector are improved.

Description

technical field [0001] The invention relates to the technical field of multi-core pre-termination products for data centers and optical communication accessories, in particular to a multi-core optical fiber connector with high reliability in plugging and unplugging, tensile resistance, compression resistance, and PIN hole anti-blocking. Background technique [0002] In recent years, with the rapid development of the data center computer room, the application scenarios of multi-core pre-terminated optical cables are increasing. The current multi-core optical fiber connectors are used as the key raw materials for the assembly of multi-core pre-terminated optical cables. There are many problems in the process: for example, when the connector is repeatedly plugged and pulled out during use, the spring in the shell will fall off in a certain proportion; the base is easy to fall off from the assembled connector; when the connector is subjected to side pressure, the stopper is easy ...

[0002] In recent years, with the rapid development of the data center computer room, the application scenarios of multi-core pre-terminated optical cables are increasing. The current multi-core optical fiber connectors are used as the key raw materials for the assembly of multi-core pre-terminated optical cables. There are many problems in the process: for example, when the connector is repeatedly plugged and pulled out during use, the spring in the shell will fall off in a certain proportion; the base is easy to fall off from the assembled connector; when the connector is subjected to side pressure, the stopper is easy to break ;During the construction process, the multi-core pre-terminated product is pulled, and the cable sheath is easy to pull off from the connector. At present, after the ordinary multi-core optical fiber connector is assembled, the cable sheath tension can only bear about 30N; Easy to block the ferrule PIN hole, etc.
