Technical Field

[0001] This utility model relates to the field of collimator technology, and in particular to a collimator connection structure. Background Technology

[0002] A collimator is an optical element used for input and output in optical fiber communication devices. Its structure is very simple. The diverging light transmitted from the optical fiber is transformed into parallel light (Gaussian beam) through a front-mounted convex lens. Its function is to couple the light into the required device with maximum efficiency or to receive the optical signal with maximum efficiency.

[0003] A fiber optic collimator connection device disclosed in patent number CN215575778U involves mounting a first fiber optic collimator and a second fiber optic collimator at opposite ends of a connecting cylinder. The first fiber optic collimator is rotatably connected to the connecting cylinder via several bearings, facilitating adjustment of the relative angle between the first and second fiber optic collimators. Furthermore, the first fiber optic collimator is connected to the connecting cylinder via a first locking member. When adjustment of the first fiber optic collimator is needed, the locking member can be released from the connecting cylinder; after adjustment, the first fiber optic collimator is re-locked in place. When the two devices rotate relative to each other during operation, the locking member can be released, achieving a rotatable connection between the two fiber optic collimators and enabling the transmission of fiber optic signals.

[0004] In the existing technology, when it is necessary to adjust the rotation of the first fiber collimator, it needs to be unsecured and then locked again after the adjustment is completed. However, when adjusting after unsecured, the collimator may vibrate slightly in the hands of the operator, which makes adjustment and calibration difficult and thus affects work efficiency.

[0008] In one embodiment of this utility model, a connecting block is slidably connected within the groove; two sets of connecting blocks are provided; connecting rods are fixedly connected to both ends of the connecting blocks; and the other end of the connecting rod is fixedly connected to the slider.

[0009] In one embodiment of this utility model, a screw is threadedly connected to the connecting cylinder; a clamping plate is fixedly connected to the end of the screw; a knob is fixedly connected to the end of the screw away from the clamping plate; and the clamping plate abuts against the collimator body.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1-5As shown, a collimator connection structure of this utility model includes a connecting cylinder 3 and a collimator body 7; a connecting ring 4 is fixedly connected to the connecting cylinder 3; two sets of connecting rings 4 are provided; the side walls of the two sets of connecting rings 4 are provided with sliding grooves 9; a snap-fit ​​assembly 22 is provided in the sliding groove 9; the snap-fit ​​assembly 22 includes a connecting box 11; a slider 10 is slidably connected in the sliding groove 9; the connecting box 11 is fixedly connected to the bottom of the slider 10; a fixing plate 12 is fixedly connected in the connecting box 11; a telescopic spring 13 is fixedly connected to the bottom of the fixing plate 12; a limit plate 17 is fixedly connected to the end of the telescopic spring 13. A pull rod 18 is fixedly connected to the inner limiting plate 17 of the telescopic spring 13; the pull rod 18 passes through the connecting box 11 and the slider 10; the limiting plate 17 is slidably connected inside the connecting box 11; a snap-fit ​​block 14 is fixedly connected to the bottom of the limiting plate 17; a hexagonal ring 15 is sleeved on the collimator body 7; a snap-fit ​​groove 16 is opened on the hexagonal ring 15; the snap-fit ​​block 14 snaps into the snap-fit ​​groove 16. During operation, the collimator body 7 is inserted into the connecting cylinder 3 for fixed connection. After connection, it is convenient for transmission between multiple sets of collimator bodies 7. During connection, a set of hexagonal rings 15 is first sleeved on the collimator body 7. The collimator body 7 has sharp edges, and the hexagonal ring 15 can be snapped onto these edges. After the collimator body 7 is fitted, it is inserted into the connecting cylinder 3. The connecting cylinder 3 contains a snap-fit ​​assembly 22, including a connecting box 11. A snap-fit ​​block 14 is located inside the connecting box 11. In the unfitted state, the snap-fit ​​block 14 extends out of the connecting box 11. When the collimator body 7 enters, the hexagonal ring 15 contacts the snap-fit ​​block 14, pushing it into the connecting box 11. During this contact, the collimator body 7 continues to be inserted until the snap-fit ​​block 14 contacts the snap-fit ​​groove 16 on the hexagonal ring 15, after which it is pushed by the telescopic spring 1 inside the connecting box 11. 3. Pop-out: Pop-out indicates successful engagement. After engagement, the operator can manually rotate the collimator body 7 for adjustment. When the collimator body 7 needs to be removed after use, the operator can pull the lever 18. When pulled, the lever 18 drives the limit plate 17 to rise, thereby driving the engagement block 14 to rise. During the rise, the telescopic spring 13 abuts against the fixed plate 12. After leaving the engagement slot 16, the engagement block 14 can extend out of the connection box 11 again due to the rebound of the telescopic spring 13. The size of the limit block is consistent with the inner diameter of the connection box 11, which can prevent the lever 18 from shaking during the rise. After pulling the engagement block 14 away from the engagement slot 16, the collimator body 7 can be removed.

[0026] In one embodiment of this utility model, a connecting block 21 is slidably connected in the slide groove 9; two sets of connecting blocks 21 are provided; connecting rods 24 are fixedly connected to both ends of the connecting block 21; the other end of the connecting rod 24 is fixedly connected to the slider 10. During operation, the connecting block 21 and the slider 10 are connected through the connecting rod 24. When rotating, the connecting block 21 can drive the slider 10 to slide in the slide groove 9.

[0027] In one embodiment of this utility model, a screw 6 is threadedly connected to the connecting cylinder 3; a clamping plate 19 is fixedly connected to the end of the screw 6; a knob 5 is fixedly connected to the end of the screw 6 away from the clamping plate 19; the clamping plate 19 abuts against the collimator body 7. During operation, after the collimator body 7 is engaged and adjusted, the operator rotates the knob 5 to drive the screw 6 to abut the clamping plate 19 against the collimator body 7 to fix the collimator body 7.

[0028] In one embodiment of this utility model, a base 1 is provided below the connecting cylinder 3; a support column 2 is fixedly connected to the base 1; the end of the support column 2 is fixedly connected to the connecting cylinder 3. During operation, the base 1 and the support column 2 can support the collimator body 7 and the connecting cylinder 3, facilitating the adjustment of the collimator body 7.

[0029] In one embodiment of this utility model, the connecting cylinder 3 is provided in two sets; the internal structure of the two sets of connecting cylinder 3 is the same, and during operation, the two sets of collimator bodies 7 are inserted into the connecting cylinder 3 together to realize transmission.

[0030] In one embodiment of this utility model, a bearing 25 is fixedly connected inside the connecting cylinder 3; an anti-slip pad 23 is fixedly connected inside the bearing 25. During operation, when the snap-fit ​​is completed, the collimator body 7 can contact the anti-slip pad 23 on the bearing 25, so that the bearing 25 can be used for rotation adjustment in a better way.

[0031] In one embodiment of this utility model, two sets of screws 6 are provided; a clamping pad 20 is fixedly connected to the bottom of the clamping plate 19. During operation, the clamping pad 20 on the clamping plate 19 can play an anti-slip role, and the two sets of screws 6 can play a bidirectional fixing role, preventing the collimator body 7 from shifting when one set of clamping plates 19 is fixed.

[0032] In one embodiment of this utility model, a rubber pad 8 is fixedly connected to the bottom of the base 1; multiple sets of support columns 2 are provided. During operation, the rubber pad 8 can play a role in preventing slippage, and multiple sets of support columns 2 are fixedly connected to the bottom of the connecting cylinder 3.

[0033] Working Principle: To overcome the slight shaking that may occur when adjusting the collimator by the operator after unfixation in existing technologies, making adjustment and calibration difficult and affecting work efficiency, the collimator body 7 is inserted into the connecting cylinder 3 for fixed connection. This connection facilitates the transfer between multiple collimator bodies 7. During connection, a set of hexagonal rings 15 are first fitted onto the collimator body 7. The collimator body 7 has corners, and the hexagonal rings 15 can be snapped onto these corners. After fitting, the collimator body 7 is inserted into the connecting cylinder 3. The connecting cylinder 3 contains a snap-fit ​​assembly 22, including a connecting box 11. A snap-fit ​​block 14 is located inside the connecting box 11. The snap-fit ​​block 14 extends out of the connecting box 11 when not snapped. When the collimator body 7 enters, the hexagonal rings 15 contact the snap-fit ​​block 14, snapping the block into place. The collimator body 7 is inserted into the connecting box 11. During the insertion, the collimator body 7 continues to be inserted until the locking block 14 contacts the locking groove 16 on the hexagonal ring 15. Then, it is ejected by the telescopic spring 13 inside the connecting box 11. The locking is completed when it is ejected. After the locking is completed, the operator can manually rotate the collimator body 7 for adjustment. When the collimator body 7 needs to be removed after use, the operator can pull the lever 18. When pulled, the lever 18 drives the limit plate 17 to rise, thereby driving the locking block 14 to rise. During the rise, the telescopic spring 13 is abutted by the fixing plate 12. After leaving the locking groove 16, the locking block 14 can be extended out of the connecting box 11 again by the rebound of the telescopic spring 13. The size of the limit block is the same as the inner diameter of the connecting box 11, which can prevent the lever 18 from shaking during the rise. After pulling the locking block 14 away from the locking groove 16, the collimator body 7 can be removed.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
