Optical fiber connector and assembly method thereof

Abstract

The invention discloses an optical fiber connector and an assembly method thereof. The connector is used for being matched with an optical fiber adapter and comprises a connector shell, a ceramic insert core, a spring and a tail sleeve, wherein the connector shell is 2.5-4.5 mm in transverse width, is formed by inserting and buckling a front shell body and a rear shell body and forms a cavity, and the tail part of the connector shell is connected with the tail sleeve; a guide convex block and a combined elastic arm are arranged on the shell external front end backward in turn set; a stopping convex block is arranged on the combined elastic arm; the tail end of the ceramic insert core is fixed with a tail seat of the ceramic insert core and passes out of a trough hole in the front end of the connector shell; and the spring is compressed between thrust blocks formed by the tail seat of the ceramic insert core and the inner wall of the connector shell. The optical fiber connector and the assembly method thereof have the beneficial effects that the overall dimension of the connector is greatly reduced on the premise that the structural strength and the use function are satisfied, and the width size of the end surface of an interface of the optical fiber connector can reach 2.5-4.5 mm, so that the installation density of the connector can be greatly improved.

Description

technical field [0001] The invention relates to an optical fiber connection device, in particular to an optical fiber connector with higher installation density and an assembly method thereof. 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 divid...

Problems solved by technology

[0008] With the large-scale advancement of FTTH (Fiber To The Home, fiber to the home), the optical fiber network is rapidly developing towards 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
