In this network, it is often necessary to jumper the core of one optical fiber line to another line. A fiber optic flange is a device that connects two optical fibers. Specifically, fiber optic connectors are installed at the ends of the two optical fibers. The two optical fibers are then inserted into the fiber optic flange, and the two end faces of the optical fibers are precisely docked so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized.

[0021] For ease of understanding, the connector plugging and unplugging auxiliary fixture is described below in conjunction with embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation and positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 to Figure 2 As shown, an auxiliary fixture for connector plugging and unplugging includes a track 1 and a connector plug-in 2 connected to the track 1, wherein the length of the track 1 is 110 mm, and there are 216 connector plug-ins on the track 1. The specific length of the track 1 can be lengthened or shortened according to the number of connector plug-ins 2. The material of the track 1 is selected to have a certain hardness to reduce the probability of deformation of the track 1 during repeated plugging and unplugging of the connector. In this embodiment, an aluminum track 1 is used.

[0025] like Figure 3 As shown, the track 1 includes a main board 11, and two raised ridges 12 are provided at the bottom of the main board 11. The two ridges 12 are parallel to each other, and the ridges 12 and the main board 11 are parallel to each other, and a groove 13 with a U-shaped cross-section is formed between the two ridges 12; a long hole 134 is provided in the middle of the track 1, which penetrates the main board 11 from top to bottom, and the long hole 134 is parallel to the main board 11. The long hole 134 is located between the two edges, and both ends of the long hole 134 are semicircular.

[0026] like Figure 2 As shown, the connector plug 2 includes a locking member, a fixing member 22 and a top screw 23. The locking member has a locking state and a non-locking state. In the locking state, the connector plug 2 is fixed relative to the track 1. In the non-locking state, the connector plug 2 can slide along the track 1. The distance between adjacent connector plugs 2 is adjustable.

[0027] like Figure 4As shown, the fixing member 22 includes a quadrangular prism-shaped main body 221, and the opposite sides of the fixing member 22 and another adjacent fixing member 22 are mutually matched, that is, the side walls between the adjacent main bodies 221 in this embodiment are completely fitted, and the fixing member 22 is 6.25 mm wide. Under this width, the fixing members 22 are closely arranged and can be applied to horizontally arranged single-joint, double-joint and quadruple-joint flanges.

[0028] like Figure 4 As shown, the top of the main body 221 protrudes upward to form a protrusion 222, and the protrusion 222 is embedded in the U-shaped groove 13 and slides along the inner wall of the groove 13; a through hole 223 is provided in the middle of the fixing member 22 to penetrate the main body 221 from front to back, and the inner wall of the through hole 223 is smooth. An optical fiber connector is inserted in the through hole 223, and the optical fiber connector includes a tail sheath wrapped at its end. The tail sheath is inserted in the through hole 223. The aperture of the through hole 223 gradually decreases from one end to the other end and then remains unchanged, so as to facilitate the insertion of the tail sheath. In this embodiment, the aperture of the through hole 223 is 4 .7mm, that is to say, in a section where the aperture remains unchanged, the aperture is 4.7mm, which is suitable for the LC tail sheath; a top screw hole 224 is provided at the bottom of the fixing member 22, and the central axis of the top screw hole 224 is perpendicular to the central axis of the through hole 223, and the top screw hole 224 and the through hole 223 are connected to each other, the inner wall of the top screw hole 224 is provided with a thread, and the outer wall of the top screw 23 is also provided with a thread, the top screw 23 and the top screw hole 224 are screwed together by threads, and one end of the top screw 23 can be inserted into the through hole 223 to squeeze and fix the optical fiber connector inserted in the through hole 223.

[0029] The optical fiber connector in this embodiment can be equipped with a latch structure (spring) and a pressing mechanism that cooperates with the latch structure to improve accuracy and reduce the convenience of the auxiliary fixture in this embodiment. The latch structure of the connector can be removed when testing the return loss.

[0030] like Figure 1 to Figure 2 As shown, the locking member in this embodiment is a bolt 21, which includes a nut and a stud. One end of the stud is fixedly connected to the nut, and the end of the stud away from the nut passes through the elongated hole 134 and is screwed to the fixing member 22. Specifically, a screw hole is provided at the top of the fixing member 22, and the screw hole and the stud are screwed together through threads. The diameter of the nut is larger than the width of the elongated hole 134, and the diameter of the stud is smaller than the width of the elongated hole 134. There is a gap between the hole wall of the elongated hole 134 and the stud, so as to avoid contact between the hole wall of the elongated hole 134 and the outer wall of the stud and reduce friction.

[0031] like Figures 1 to 4As shown, the usage steps are as follows: confirm the spacing between adjacent connector plug-ins 2, insert the fixing parts 22 from the rear of the optical fiber connector in sequence, with the protrusions 222 facing upward, buckle the grooves 13 of the track 1 on the fixing parts 22 arranged side by side, lock the fixing parts 22 on the track 1 with bolts 21, and tighten the top screw 23. The top screw 23 fixes the optical fiber connector so that only the tail sheath is left on the outside after the optical fiber connector is inserted into the flange.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
