[0019] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. For the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1 - 12 , a waveguide converter for a filter, including a converter main body 1, a transmitting optical fiber 2, a receiving optical fiber 3, a mounting and connecting component, and a stabilizing component.

[0021] Among them, the present invention also symmetrically arranges connection sockets 11 at both ends of the converter main body 1, and symmetrically arranges connection side plates 12 at the side positions of the connection sockets 11, and first mounting holes 13 are penetrated through the connection side plates 12; the transmitting optical fiber 2 is inserted into the connection socket 11 at one end of the converter main body 1, and a mounting plate member 41 is fixedly arranged on the side of the transmitting optical fiber 2, and a second mounting hole 42 is arranged on the mounting plate member 41.

[0022] In this solution, for the connection and fixation of the transmitting optical fiber 2 to the converter body 1, the plug head of the transmitting optical fiber 2 is inserted into the connection socket 11 at the end of the converter body 1 until the mounting plate member 41 provided on the transmitting optical fiber 2 is in close contact with the connection side plate 12 at the end of the converter body 1. At the same time, the second mounting hole 42 provided on the mounting plate member 41 is aligned with the first mounting hole 13 on the connection side plate 12, and then it is fixedly connected through the provided mounting connection assembly. Here, one end of the connection threaded post 501 in the mounting connection assembly is fixedly provided with a stabilizing baffle 502, the side wall of the connection threaded post 501 is equidistantly provided with rectangular through slots 503, the other end of the connection threaded post 501 is fixedly provided with a docking plug 504, and a fastening card slot 505 is provided in the docking plug 504. The docking plug 504 is connected to the stabilizing assembly; among them, the rectangular through slots 503 are communicated; the connection threaded post 501 is threadedly connected to the internal thread fastening cap 506. The side wall of the internal thread fastening cap 506 is equidistantly provided with auxiliary through slots 507. The notch width of the auxiliary through slots 507 is larger than the notch width of the rectangular through slots 503. The end diameter of the connection threaded post 501 is set to be equal to the aperture of the first mounting hole 13; that is, the connection threaded post 501 is inserted from the second mounting hole 42 on the mounting plate member 41 and then passes through the first mounting hole 13 on the connection side plate 12, so that the stabilizing baffle 502 at one end of the connection threaded post 501 is in close contact with the mounting plate member 41, and then the internal thread fastening cap 506 is threadedly tightened with the connection threaded post 501.

[0023] In order to further improve the thread connection stability between the connection threaded post 501 and the internal thread fastening cap 506, that is, to improve the connection stability between the transmitting optical fiber 2 and the converter body 1, this solution also provides a rubber chuck 508. One end of the rubber chuck 508 is fixedly provided with an auxiliary pull head 509. The two sides of the rubber chuck 508 are symmetrically provided with auxiliary inclined surfaces, and auxiliary convex strips 510 are equidistantly fixed on the auxiliary inclined surfaces. Among them, the symmetrically arranged auxiliary inclined surfaces on both sides of the rubber chuck 508 make the head of the rubber chuck 508 narrower. That is, after the internal thread fastening cap 506 is tightened, it is directly inserted from one of the auxiliary through slots 507 on the side of the internal thread fastening cap 506 until the head of the rubber chuck 508 is inserted into the corresponding rectangular through slot 503 on the side of the connection threaded post 501. It has a clamping and locking effect on the thread connection between the internal thread fastening cap 506 and the connection threaded post 501; it should be noted here that if after tightening the internal thread fastening cap 506, some of the auxiliary through slots 507 on the internal thread fastening cap 506 are aligned with the rectangular through slots 503 on the side of the connection threaded post 501, some are misaligned, and some may be blocked. When inserting the rubber chuck 508, just find the ones where the auxiliary through slots 507 are aligned or partially staggered with the rectangular through slots 503.

[0024] When using the rubber clamp 508 to clamp and lock the connection between the internal thread fastening cap 506 and the connecting threaded column 501, in order to improve the clamping stability of the rubber clamp 508, this solution also provides an auxiliary ridge 510 on the auxiliary inclined surface on the side of the rubber clamp 508 to provide an anti-slip effect; an auxiliary pull head 509 is provided at the tail end of the rubber clamp 508, which facilitates the removal of the rubber clamp 508 when it is necessary to release the connection lock between the internal thread fastening cap 506 and the connecting threaded column 501, thereby improving the convenience of operation.

[0025] In this solution, the receiving optical fiber 3 is connected and fixed, and the receiving optical fiber 3 is plugged into the other end of the converter body 1, and a mounting plate 41 is also fixedly provided on the side of the receiving optical fiber 3. The second mounting holes 42 on the mounting plate 41 correspond to the first mounting holes 13 on the connecting side plate 12 in corresponding positions, have the same number of groups, and have the same aperture settings. The installation of the receiving optical fiber 3 is the same as the installation operation of the transmitting optical fiber 2.

[0026] After the transmitting optical fiber 2 and the receiving optical fiber 3 are connected to the two ends of the converter body 1 respectively, they can also be used in conjunction with the provided stabilizing component and the installation connection component. In short, the transmitting optical fiber 2 and the receiving optical fiber 3 are fixedly connected to the converter body 1 through the provided installation connection component, and are fastened by the provided stabilizing component; while further improving the stability of the connection between the transmitting optical fiber 2 and the receiving optical fiber 3, it also has a corresponding positive effect on the overall stability of the converter; the end face of one end of the first connecting rod 701 in the stabilizing component is provided with a docking slot 707, the docking slot 707 is adapted to be plugged in with the docking plug block 504, and the side of the docking slot 707 is symmetrically provided with positioning threaded holes 708, the positioning threaded holes 708 are threadedly connected with the positioning screws 709, and the first connecting rod 701 The other end is fixedly provided with an externally threaded docking column head 702, and the positioning threaded hole 708 corresponds to the setting position of the fastening slot 505 on the docking plug block 504. The notch shape of the docking slot 707 is set to be square, and the end shape of the docking plug block 504 is also set to be square; one end of the second connecting rod 704 is fixedly provided with a limiting baffle 703, and the end face of the other end of the second connecting rod 704 is also provided with a docking slot 707, and the second connecting rod 704 is movably provided with an internally threaded pulling pipe fitting 705, and the inner side wall of one end of the internally threaded pulling pipe fitting 705 is provided with a limiting ring piece 706; the outer side wall of the internally threaded pulling pipe fitting 705 is equidistantly fixed with anti-slip convex strips, and the setting positions of the internally threaded pulling pipe fitting 705 and the externally threaded docking column head 702 correspond to each other, the setting number of groups is the same, and the two are adapted to be threadedly connected.

[0027] During the operation process, on the one hand, when connecting and installing the transmitting optical fiber 2 and the receiving optical fiber 3, the internal thread fastening cap 506 can be tightened with the internal thread fastening cap 506 first, and then the internal thread tensioning pipe fitting 705 is rotated to be threadedly connected with the external thread docking head 702, so that the first connecting rod 701 and the second connecting rod 704 form a tensioning effect, which is not only beneficial to the stable connection of the transmitting optical fiber 2 and the receiving optical fiber 3, but also has a corresponding positive effect on the overall stability of the converter.

[0028] For the stable connection of the transmitting optical fiber 2 and the receiving optical fiber 3, in this solution, after the connecting threaded post 501 passes through the second installation hole 42 and the first installation hole 13 at one time, the internal thread fastening cap 506 can be threadedly connected to the connecting threaded post 501 first, but it does not need to be tightened. Then, the docking plug 504 at the end of one connecting threaded post 501 is inserted into the docking slot 707 at one end of the first connecting rod 701, and the docking plug 504 at the end of the other connecting threaded post 501 is inserted into the docking slot 707 at one end of the second connecting rod 704. At this time, the fastening card slot 505 provided on the docking plug 504 is aligned with the positioning threaded hole 708 on the side of the docking slot 707, and then it is fixedly connected by the positioning screw 709. After the connection and fixation, at this time, the external thread docking head 702 at the other end of the first connecting rod 701 does not contact the limit retaining plate 703 at the end of the second connecting rod 704, and there is still a certain distance between them. That is, at this time, the internal thread tensioning pipe fitting 705 is directly rotated until the internal thread tensioning pipe fitting 705 is threadedly connected to the external thread docking head 702, and finally the external thread docking head 702 is tightened so that the first connecting rod 701 and the second connecting rod 704 provide a tensioning effect. During the tensioning, the stabilizing baffle 502 at one end of the connecting threaded post 501 is made to fit closer to the mounting plate member 41, and also makes the mounting plate member 41 fit closer to the connecting side plate 12 at the end of the converter body 1; then the internal thread fastening cap 506 is rotated until it is tightened. During this process, the tensioning effect of the connection between the first connecting rod 701 and the second connecting rod 704 can be utilized to make the position of the connecting threaded post 501 more stable. Furthermore, when finally tightening the internal thread fastening cap 506, there is no need to hold or press the stabilizing baffle 502 by hand to tighten the internal thread fastening cap 506. Generally, auxiliary tools such as a wrench are needed to fix the stabilizing baffle 502 to better tighten the internal thread fastening cap 506. However, this operation process does not require the use of auxiliary tools anymore. After tightening the internal thread fastening cap 506, the rubber chuck 508 is used for clamping and locking; when rotating or loosening the internal thread tensioning pipe fitting 705, this solution also provides anti-slip ridges on the outer side wall of the internal thread tensioning pipe fitting 705 to facilitate the operation of the staff.

[0029] For the use of the installation connection component, when the internal thread fastening cap 506 is screwed onto the connection threaded post 501, the auxiliary through groove 507 provided on the side of the internal thread fastening cap 506 can, on the one hand, cooperate with the rectangular through groove 503 on the side of the connection threaded post 501, and the rubber chuck 508 is inserted to provide a clamping and locking function. On the other hand, the auxiliary through groove 507 provided on the side of the internal thread fastening cap 506 can also provide an anti-slip function when the internal thread fastening cap 506 is loosened or tightened. That is, the auxiliary through groove 507 at this time acts as an anti-slip groove.

[0030] In addition to the auxiliary through groove 507 in the internal thread fastening cap 506 and the rectangular through groove 503 in the connection threaded post 501 cooperating with the rubber chuck 508 to provide a clamping and locking function, they can also cooperate with the auxiliary communication cavity groove 6. That is, the auxiliary communication cavity grooves 6 are symmetrically provided in the connection side plate 12. One end of the auxiliary communication cavity groove 6 is communicated with the first installation hole 13, and the other end of the auxiliary communication cavity groove 6 is communicated with the end connection socket 11 of the converter main body 1. After the connection threaded post 501 passes through the first installation hole 13 in the connection side plate 12, the rectangular through groove 503 at the corresponding position on the connection threaded post 501 is communicated with the auxiliary communication cavity groove 6, and the rectangular through groove 503 is communicated with the outside. After the transmitting optical fiber 2, the receiving optical fiber 3 and the converter main body 1 are connected, during the information processing work, it can also provide a corresponding auxiliary cooling effect on the heat at their connection, which can also provide certain positive help for the stable operation of the converter.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
