TECHNICAL FIELD

[0001] The utility model relates to the field of APC single core connecting structure, especially APC single core connecting structure. BACKGROUND

[0002] In today's era of rapid development of science and technology, various electronic devices, communication systems and precision instruments are widely used in various fields of people's life and production. In these devices and systems, the realization of signal transmission, medium transportation and other functions cannot be separated from reliable connecting structure. As a kind of key connecting component, APC single core connecting structure is responsible for realizing efficient and stable transmission of optical signal in the field of optical fiber communication; in medical equipment, chemical fluid conveying pipeline and other aspects, it guarantees the safe conveying of liquid or gas. Its performance is directly related to the running stability, reliability and service life of the whole system, and plays a crucial role in the development of modern science and technology and the efficient production of industrial production.

[0003] At present, the traditional APC single core connecting structure has many drawbacks. In terms of connection stability, some existing connecting structure designs are simple, and most of them adopt plug-in connection mode. After being subjected to external vibration, temperature change or long-term use, the connection part is prone to looseness. For example, in the communication base station, due to the vibration generated during the operation of the equipment, the APC single core connection of plug-in type may gradually loosen, resulting in unstable optical signal transmission, and even interrupting communication. This is because the plug-in connection lacks effective fastening and positioning measures,

In terms of sealing performance, the sealing method and material selection of the existing connecting structure have defects. The sealing ring of some connecting structure is easy to age and wear, and the sealing effect is greatly reduced. Impurities such as dust and moisture from outside are easy to invade, and internal medium may also leak. Like in chemical production, if the connecting part of the pipeline conveying corrosive liquid is not sealed well, not only will it cause liquid leakage and pollute the environment, but also may corrode the equipment and cause safety accidents. In addition, the existing connecting structure is difficult to meet the demand in operation convenience, and the complex installation steps and debugging process increase the cost and time cost. Therefore, in view of the problems that the sealing method and material selection of the existing connecting structure have defects and the existing connecting structure is difficult to meet the demand in operation convenience, a kind of APC single core connecting structure is needed to solve the above problems.
