Technical Field
The invention belongs to the technical field of optical fibers, and particularly relates to an optical fiber coupler and an optical fiber plug.
Background
The utility model provides a device that can dismantle the connection between fiber coupler optic fibre and the optic fibre, it is the accurate butt joint of two terminal surfaces of optic fibre, so that the light energy that the transmission optic fibre output can furthest couple to receiving optic fibre, thereby make it intervene the optical link and lead to the fact the influence to the system to minimum, when optic fibre during the use, can take place to crooked because of various exogenic actions, when the crooked too big of optic fibre, the functionality of optic fibre will be influenced, when the installation environment is in narrow and small space or when being inconvenient for direct installation fiber plug, in order to satisfy the installation of optic fibre, the strength control of palm is bad, make optic fibre crooked too big, we need a device, avoid the effort of palm to optic fibre at the in-process of fiber plug insertion fiber coupler.
The special optical fiber coupler provided by a chinese patent with application number CN201610853955.0 comprises an input optical fiber and an output optical fiber, wherein more than two optical fiber rings coupled with each other are arranged between the input optical fiber and the output optical fiber, the coupling parts of two adjacent optical fiber rings are tightly fused together, and the input optical fiber, the output optical fiber and the optical fiber rings are all formed by gain optical fibers; by adopting the structure, because the optical fiber rings are fused together in sequence, when pump light enters the coupler through the input optical fiber, the pump light circulates back and forth in the coupler similar to a black hole, the path of the pump light in the gain optical fiber is greatly increased, and because the gain optical fiber absorbs and excites the pump light through the cladding doped rare earth element to generate a gain effect, the absorption times of the pump light with the same energy by the gain optical fiber in the gain optical fiber with the same length are greatly increased, thereby improving the utilization rate of the pump light. However, this patent does not address the problem of excessive bending of the optical fiber caused by the palm force of a person when the fiber plug is inserted into the fiber coupler.
In view of the above, the present invention provides an optical fiber coupler and an optical fiber plug, which solve the above problems.
Disclosure of Invention
In order to make up the defects in the prior art, the invention provides the optical fiber coupler and the optical fiber plug, and the acting force of a palm on an optical fiber during insertion is reduced by arranging the sliding plate and the wire frame, so that the bending degree of the optical fiber is reduced, and the optical fiber is protected to be bent in a normal range.
The technical scheme adopted for solving the technical problems is as follows: the invention relates to an optical fiber coupler, which comprises an optical fiber protective sleeve, wherein a sliding groove is formed in a port of the optical fiber protective sleeve, a sliding plate is slidably arranged in the sliding groove, one side of the sliding plate, which is far away from the optical fiber protective sleeve, is fixedly connected with a U-shaped wire frame, and an opening in the center part of the wire frame is a jack; and a tension spring is arranged in the sliding groove, one end of the tension spring is fixedly connected with the bottom of the sliding groove, and the other end of the tension spring is fixedly connected to one side of the sliding plate, which is close to the optical fiber coupler.
