In a CMOS camera, multiple optical fibers are often fixed by a coupling device, and the optical fibers are coupled to the light-receiving surface of the CMOS camera. However, the existing optical fiber coupling device can only fix one row of optical fibers on each side, that is, when the number of optical fibers in a CMOS camera increases, the cross-sectional area of ​​the optical fiber coupling device is larger, and the space occupied by the optical fiber coupling device is also larger. Utility Model Content

[0003] In order to overcome the defects of the prior art, the utility model provides an optical fiber coupling device for a CMOS camera, which can fix more optical fibers in a smaller space.

[0013] In one embodiment, the screwing groove of the machine screw faces the outside of the threaded hole.

[0014] The beneficial effect of adopting the above technical solution is: such an arrangement makes it convenient to insert a screwdriver into the threaded hole to tighten the machine screw.

[0015] In one embodiment, the cross section of the plate is square.

[0016] In one embodiment, the through holes on the front and rear sides of the plate body are located between the through holes on the left and right sides of the plate body.

[0017] The beneficial effect of adopting the above technical solution is that the planar layout of the optical fibers is more reasonable.

[0019] The beneficial effects of adopting the above technical solution are: the plate body can be engaged with the CMOS camera through the snap-fitting part, and can be detachably connected to the CMOS camera through the connecting part. At the same time, since the cross-sectional size of the connecting part is larger than the cross-sectional size of the snap-fitting part, the connecting part can limit the axial connection position of the plate body.

[0020] In one embodiment, mounting holes for screw connection with a CMOS camera are provided at four corners of the connecting portion.

[0021] The beneficial effect of adopting the above technical solution is: by installing screws into the mounting holes at the four corners and threading the screws with the CMOS camera, the plate can be fixedly connected to the CMOS camera.

[0034] The utility model will be further described below in conjunction with the accompanying drawings.

[0035] The utility model provides a fiber coupling device for a CMOS camera, such as Figure 1-3As shown, it includes a steel plate body 1, each side of the plate body 1 is vertically provided with a plurality of through holes 2 for optical fiber insertion and limiting, and the plurality of through holes 2 on each side are arranged in rows and columns, and the number of rows is at least two rows; each side of the plate body 1 is horizontally provided with a plurality of threaded holes 3, and the plurality of threaded holes 3 on each side are distributed in columns, and the number of columns and the column positions of the threaded holes 3 respectively match the number of columns and the column positions of the through holes 2 on the same side, and the threaded holes 3 are connected to all the through holes 2 in the same column position on the same side; and the outer side of any through hole 2 is provided with a machine screw threadedly connected to the threaded hole 3.

[0036] It can be understood that multiple rows of optical fibers can be inserted and limited on each side of the plate body 1 through multiple rows of through holes 2, that is, more optical fibers can be fixed in a smaller space, and the multiple optical fibers inserted in the same column of through holes 2 on each side can be fastened by multiple machine screws installed from the same column of threaded holes 3 on the same side, which is conducive to fixing more optical fibers in a smaller space; in addition, multiple optical fibers are limited and fixed on the same plane on the same plate body 1, so that the multiple optical fibers can be installed on the CMOS camera with the plate body 1, thereby facilitating the coupling of the multiple optical fibers with the photosensitive receiving surface of the CMOS camera.

[0037] In one embodiment, Figure 1 As shown, two rows and six columns of through holes 2 are provided on the left and right sides of the plate body 1, six threaded holes 3 are provided on the left and right sides of the plate body 1, two rows and two columns of through holes 2 are provided on the front and rear sides of the plate body 1, two threaded holes 3 are provided on the front and rear sides of the plate body 1, and each threaded hole 3 is connected to the two through holes 2 in the same column; in addition, the threaded hole 3 between the two through holes 2 in the same column is threadedly connected with a machine screw to fasten the optical fiber inserted in the inner through hole 2 in the same column, and the threaded hole 3 on the outer side of the through hole 2 in the same column is threadedly connected with a machine screw to fasten the optical fiber inserted in the outer through hole 2 in the same column, and at the same time, the two machine screws are installed and adjusted in the same threaded hole 3.

[0038] It should be noted that when installing optical fibers in each column of through holes 2 on each side, the optical fibers are first inserted into the inner through holes 2, and then the machine screws are screwed into the threaded holes 3 in the same column on the same side to fasten the optical fibers in the inner through holes 2. Afterwards, the optical fibers are inserted into the outer through holes 2, and then the machine screws are screwed into the same threaded holes 3 to fasten the optical fibers in the outer through holes 2.

[0039] In one embodiment, the front end of the optical fiber is configured as a step axis, the aperture of the through hole 2 is not less than the front end diameter of the step axis, and the aperture of the through hole 2 matches the front end diameter of the step axis.

[0040] It can be understood that such a configuration enables the front end of the step shaft on the optical fiber to be inserted into the through hole 2, and the rear end of the step shaft on the optical fiber to be unable to be inserted into the through hole 2, so as to axially limit the optical fiber through the through hole 2; the aperture of the through hole 2 matches the front end diameter of the step shaft, so that the front end of the step shaft on the optical fiber can just fit into the through hole 2, thereby facilitating the radial limitation of the optical fiber.

[0041] In one embodiment, the length of the machine screw is not greater than the minimum distance between two adjacent through holes 2 in the same row.

[0042] It can be understood that the length of the machine screw is not greater than the minimum distance between two adjacent through holes 2 in the same row, so as to avoid the outer part of the machine screw existing in the outer through hole 2 when the optical fiber in the inner through hole 2 is fastened by the machine screw, thereby avoiding the machine screw from interfering with the installation of the optical fiber.

[0043] In one embodiment, the screwing groove of the machine screw faces the outside of the threaded hole 3, which facilitates inserting a screwdriver from the threaded hole 3 to screw the machine screw.

[0044] In one embodiment, the cross section of the plate body 1 is square.

[0045] In one embodiment, the through holes 2 on the front and rear sides of the board body 1 are located between the through holes 2 on the left and right sides of the board body 1, so that the planar arrangement of the optical fibers is more reasonable.

[0046] In one embodiment, the board body 1 includes a clamping portion 101 for clamping with a CMOS camera and a connecting portion 102 for detachably connecting with the CMOS camera. The connecting portion 102 is located at one end of the clamping portion 101 , and the cross-sectional size of the connecting portion 102 is larger than the cross-sectional size of the clamping portion 101 .

[0047] It can be understood that the board body 1 can be engaged with the CMOS camera through the clamping portion 101, and can be detachably connected to the CMOS camera through the connecting portion 102. At the same time, since the cross-sectional size of the connecting portion 102 is larger than the cross-sectional size of the clamping portion 101, the connecting portion 102 can limit the axial connection position of the board body 1.

[0048] It should be noted that when the fiber optic coupling device is not installed on the CMOS camera, a step groove is provided thereon, and a light-sensitive receiving surface is provided at the bottom of the step groove; when the fiber optic coupling device is installed on the CMOS camera, the clamping portion 101 of the plate body 1 is engaged with the lower portion of the step groove, and the connecting portion 102 of the plate body 1 is installed on the upper portion of the step groove.

[0049] In one embodiment, four corners of the connection portion 102 are provided with mounting holes 4 for screw connection with a CMOS camera.

[0050] It can be understood that by installing screws into the mounting holes 4 at the four corners and threading the screws with the CMOS camera, the plate body 1 can be fixedly connected to the CMOS camera.

[0051] In one embodiment, the plate body 1 is an opaque plate to prevent imaging from being affected by light leakage.
