Problems solved by technology

[0008] With the large-scale promotion of FTTH (Fiber To The Home, fiber to the home), the optical fiber network is developing rapidly in the direction of larger bandwidth and larger capacity, and the demand for the number of optical fiber handovers in the optical access network is increasing. The demand for the transfer capacity of the equipment is also increasing, and the installation density of the optical fiber connector is required to be higher and higher, and the corresponding volume is getting smaller and smaller. On the basis of keeping the physical volume of existing equipment unchanged, the installation density of optical fiber connectors can be increased, but the structure and assembly process of the existing optical fiber connectors mentioned above are not able to meet this demand
[0009] At the same time, the external shell of the existing optical fiber connector is generally divided into two parts. For example, SC is divided into inner and outer frame sleeves, and LC is divided into front and rear shells. The manufacturing process of the two-part shell is relatively complicated, and the process required for installation It is also relatively complicated, and the fiber optic connector housings composed of two parts are usually fixedly connected by buckles. Multiple plugging and unplugging may cause the connection strength to decrease. The connection between the two is not firm and affects the product. For normal use, only new products can be replaced, which will increase the cost of manufacturing and use while causing waste

Abstract

The invention discloses an optical fiber accessing plug with an integrated housing. The optical fiber accessing plug with the integrated housing comprises a housing, an inserting core subassembly connected with optical fiber and a tail protecting bush, wherein the inserting core subassembly comprises a ceramic inserting core and a ceramic inserting core tailstock fixed with the ceramic inserting core; the housing adopts an integrated cavity structure; a through hole is arranged at the front end of the housing, and a tail pipe is inserted into the tail part of the housing; the ceramic inserting core penetrates through the through hole; the front part of the tail pipe is in interference fitting with the internal wall of the housing through a backstopping barb on the external wall thereof; the tail protecting bush is connected with the back part of the tail pipe; and a spring used for providing fitting force for a plug in butting is arranged in an internal chamber of the housing between the ceramic inserting core tailstock and the tail pipe. According to the optical fiber accessing plug with the integrated housing provided by the invention, the housing adopts the integrated cavity structure and is composed of two parts compared with an existing plug, which is simpler in structure, and is more convenient and quicker in the producing and assembling processes; and the problem that the connection strength between parts of the structure comprising two parts is reduced during mutually plugging process can be avoided.

Description

technical field [0001] The invention relates to an optical fiber connection device, in particular to an optical fiber access plug with an integral housing. Background technique [0002] Optical fiber communication has become one of the main pillars of modern communication and plays a pivotal role in modern telecommunication networks. The development of network technology has made optical fiber more and more widely used as a transmission medium for high-speed and broadband data communication. Optical fiber connector is a device for detachable (movable) connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. And minimize the impact on the system due to its intervention in the optical link. At present, the commonly used optical fiber connectors can be divided into various forms according to th...
