Referring to fig. 1 to 5, the present embodiment provides an optical fiber fixing device, which mainly includes an optical fiber fixing member 10, an optical fiber limiting member 20, and an optical fiber calibrating member 30; the following are described separately.

Referring to fig. 1 to 5, the optical fiber fixing member 10 is mainly used as a fixing carrier of the optical fiber a, and it can be understood that the optical fiber fixing member 10 is equivalent to an existing optical fiber bracket or a part of the optical fiber bracket, and after the optical fiber a is fixed on the optical fiber fixing member 10, the optical fiber fixing member 10 and the capillary bearing member can be structurally combined, so that the optical fiber a can be aligned with the capillary one by one finally; the front end of the optical fiber fixing member 10 is provided with a plurality of fixing hole sites a arranged at intervals in the left-right direction (i.e. the plurality of fixing hole sites a are arranged at intervals along a straight line distributed in the left-right direction), the fixing hole sites a penetrate through the optical fiber fixing member 10 in the up-down direction and are mainly used for accommodating the first end of the optical fiber A, and after the pre-fixing posture of the optical fiber A is determined, at least one part of the second end of the optical fiber A can be completely fixed in the fixing hole sites a (i.e. glue fixing) by filling fixing media such as glue in the fixing hole sites a. It should be noted that, since the optical fiber a is a straight line-segment structure that is cut from an optical fiber blank in advance according to a predetermined length, two end portions can be naturally formed on the optical fiber a.

Referring to fig. 1, 2, 3 and 5, the optical fiber limiting member 20 is mainly used for limiting the second end of the optical fiber a, so as to limit the two ends of the optical fiber a under the coordination of the fixing hole a; the optical fiber stopper 20 is detachably disposed on the optical fiber fixing member 10 in a manner such as a snap connection, a socket connection, a magnetic connection, etc., and a main body portion thereof is located at an upper side of the optical fiber fixing member 10 so as to be capable of forming a certain interval distance in an up-down direction with the optical fiber fixing member 10; meanwhile, a plurality of limiting slot slots b are formed in the side wall of the front end of the optical fiber limiting part 20 and are arranged at intervals in the left-right direction, the limiting slot slots b extend in the front-back direction and penetrate through the optical fiber limiting part 20 in the up-down direction, and meanwhile, the fixing hole positions a and the limiting slot slots b are in one-to-one correspondence in the up-down direction and are mainly used for accommodating the second end part of the optical fiber A, so that the constraint limitation on the second end part of the optical fiber A is realized; specifically, after the first end of the optical fiber a is inserted into the fixing hole a, the second end of the optical fiber a can enter the limiting slot b, and by selecting the alignment relationship and the form and size between the fixing hole a and the limiting slot b and utilizing the straight structural form of the optical fiber a, when the peripheral wall of the second end of the optical fiber a abuts against the bottom of the limiting slot b, the center line of the optical fiber a coincides with the center line of the fixing hole a, so that the end face of the first end of the optical fiber a is in a horizontal plane (i.e., the end face of the optical fiber a and the port of the fixing hole a are in the same plane or in a parallel distribution state). The groove bottom of the restriction slit b refers to a groove surface on the rear end side of the restriction slit b, the groove surface corresponds to the notch of the restriction slit b in the front-rear direction, and the groove surface between the groove surface and the notch may also be referred to as a groove wall.

Based on this, the constraint and limitation of the two end portions of each optical fiber a are realized by using the one-to-one correspondence relationship between the fixed hole site a and the limiting slot b, after the plurality of optical fibers a are installed on the optical fiber fixing member 10 and the optical fiber limiting member 20 one by one, the motion relationship of the optical fiber calibration member 30 relative to the optical fiber limiting member 20 can be used to synchronously apply thrust to all the optical fibers a, so that the peripheral wall of the second end portion of the optical fiber a can abut against the slot bottom of the limiting slot b, and the center line of the optical fiber a can coincide with the center line of the fixed hole site a, thereby completing the synchronous adjustment and limitation of the inclination amplitude of the optical fiber a, ensuring that the end surface of the first end portion of the optical fiber a can be in the same horizontal position (it can also be understood that the end surface of the first end portion of the optical fiber a and the port surface of the fixed hole site a are in the same plane or parallel to each other), the consistency of the assembly of the plurality of optical fibers A is realized. On one hand, based on the structural alignment and relative motion relationship between the optical fiber calibration part 30 and the optical fiber limiting part 10, the tilt amplitude of the optical fiber A is finely adjusted and limited, so that the problem that the tilt amplitude of the optical fiber A is adjusted manually and inaccurately can be effectively solved, and the fixed assembly quality of the optical fiber A is effectively improved; on the other hand, the optical fiber calibration piece 30 is used for synchronously realizing fine adjustment and limitation on the inclination amplitude of the optical fibers A, so that the end faces of the optical fibers A can be positioned at the same horizontal position, the problems of time and labor waste, high labor intensity and the like caused by manual one-by-one operation can be solved, and favorable conditions are created for improving the assembly efficiency of the optical fibers A.
