Description

Environment-resistant small-circular high-density optical fiber connector assembly

Technical Field

The utility model relates to a connector specifically is a be applied to the little circular high density fiber connector subassembly of resistant environment of transmission signal under adverse circumstances such as the space is little, corrosion-resistant.

Background

At the end of the twentieth century, two key technologies, namely a laser and a low-loss optical fiber, are greatly broken through, so that the application development of optical fiber communication is not beneficial, and the technology is updated very quickly. Optical fiber communication is almost free from consideration of electromagnetic interference factors because quartz optical fiber is insensitive to electromagnetic fields, and the loss rate of optical fiber transmission is extremely low, which is self-evident in comparison with conventional cable transmission. But everything is twofold, optical fiber is no exception, and the fragile physical characteristics and environmental resistance are the largest short boards.

The traditional optical fiber connector adopts a pin and jack structure, and if the traditional optical fiber connector is applied to the field of high tips, the problems of structure looseness, damage and unstable signal transmission are easily caused by severe natural environment and use environment; in addition, when signals are transmitted in small space occasions, the traditional pin and jack structure tends to cause the connection volume to be too large, and the small space application cannot be adapted.

Disclosure of Invention

In order to solve the deficiency among the prior art, the utility model provides a can compromise the compact structure of miniaturized installation, prevent that the pine from taking off, improve the resistant environment small circle high density fiber connector subassembly stable in utilization, safety.

The utility model adopts the technical proposal that: the utility model provides a resistant small circle shape high density fiber connector subassembly of environment, includes plug and socket, its characterized in that: a plug limiting ring is sleeved in a head shell of the plug, an MT optical fiber plug part is connected in the plug limiting ring in a penetrating manner, two guide pins are respectively connected to two sides of the MT optical fiber plug part in a penetrating manner, a spring push block is arranged at the rear part of the MT optical fiber plug part and abuts against the guide pins to be connected with the rear end of the MT optical fiber plug part in a penetrating manner, the rear end of the spring push block abuts against a spring, and the spring abuts against the plug tail ring at the rear part of the screwing plug limiting ring; the MT optical fiber socket part is connected in the socket shell in a penetrating mode, and guide holes corresponding to the penetrating guide pins are formed in the MT optical fiber socket part.

Furthermore, the tail ring of the plug is connected with the tail accessory in a rear mode.

Furthermore, the rear part of the seat shell is connected with a seat tail ring, and the front end of the seat tail ring is tightly propped against the MT optical fiber socket part to be limited in the seat shell.

Furthermore, the penetrating connection between the inside of the head shell and the inside of the seat shell and the inside of the MT optical fiber plug part and the MT optical fiber socket part respectively adopts a rectangular hole cavity.

After adopting above technical scheme, the beneficial effect who reaches is:

the MT optical fiber plug part and the MT optical fiber socket part adopt high-density multi-core armored optical cables different from conventional optical cables, compared with the traditional single-core optical fiber, the MT optical fiber plug part and the MT optical fiber socket part have the advantages that the strength is guaranteed, the transmission speed is greatly improved, the weight is obviously reduced, and the MT optical fiber plug part and the MT optical fiber socket part can be more suitable for various severe use environments; the guide pin guide insertion reduces errors generated when the connector is in butt joint, can ensure the butt joint precision of the MT optical fibers under the environments of vibration and impact, and enhances the reliability of signal transmission.

This connector assembly adopts MT fiber optic plug portion, MT fiber optic socket portion butt joint transmission, and the cooperation is in head, the interior rectangle vestibule cross-under of seat casing, can compromise on guaranteeing transmission signal volume and reduce installation space and whole volume size, cooperates the pilot pin simultaneously and supports tightly the grafting guiding hole through the spring ejector pad, has improved grafting stability, can guarantee the reliable transmission of signal under the shock impact environment, is applicable to the operation under various adverse circumstances.
