Description

Optical fiber connecting assembly

Technical Field

The invention relates to the technical field of optical fiber communication, in particular to a miniaturized packaged optical fiber physical butt joint structure, and particularly relates to an optical fiber connecting assembly.

Background

The connection between the optical fiber and the connection between the optical fiber and the equipment are basically realized through an optical fiber connector. With the explosive increase of information internet and cloud service, the requirement for optical fiber connection density is continuously increased, that is, more optical fiber connections are required to be realized in a unit volume, and the required engineering operation space is required to be smaller and smaller when the connector is in butt joint with the adapter. Generally, as shown in fig. 1 to 4, enough assembly and engineering construction space must be reserved for the locking and unlocking mechanisms of the connector and the adapter thereof inside the conventional distribution box or distribution box, and as the product density is higher and higher, a large amount of precious space inside the distribution box or distribution box is occupied by operation actions which may be performed only once or a few times, which is very wasteful.

Specifically, in the current optical fiber connection scenario, the following problems mainly exist: (1) the unlocking component of the optical fiber connector can make the structure of the optical fiber connector become complex or the number of parts is too large, so that the cost of the optical fiber connector is high, and the difficulty of the manufacturing process of the optical fiber connector is increased by many times; (2) the unlocking member of the optical fiber connector increases the volume of the optical fiber connector, and particularly, when the unlocking member is arranged on the inner side of the wiring box or the wiring box, the unlocking member of the optical fiber connector occupies a large space inside the wiring box or the wiring box; (3) the optical fiber connector may have an unlocking component, and when the optical fiber connector and the adapter perform an unlocking action, the optical fiber connector may occupy a space inside the wiring box or the wiring box, so that when the optical fiber connector and the adapter are arranged inside the wiring box or the wiring box, an engineering operation space for unlocking (where any other device cannot be arranged) must be reserved, which is not favorable for the miniaturization design of the wiring box or the wiring box.

Therefore, there is still room for improvement in the existing connector and its connector assembly, and it is necessary to optimize the structure and usage method thereof, so as to simplify the connection structure and optimize the usage effect, and achieve the purpose of saving the internal space of the wiring box or the wiring box, thereby improving the device and module capacity inside the wiring box or the wiring box, or facilitating the miniaturization design of the wiring box or the wiring box.
