Description

Technical Field

[0001] This invention relates to the field of rotating fiber optic connector technology, specifically a rotatable MTP fiber optic connector. Background Technology

[0002] MTP (Multi-Pack Rotatable Plug) fiber optic connectors are commonly used in high-density fiber optic transmission systems. Compared to ordinary fiber optic connectors, MTP connectors have multiple fiber channels and can rotate. When using MTP connectors, the connecting cables at both ends are relatively long, which can easily tangle, making the connector less convenient to carry.

[0003] For example, Chinese invention patent CN212111878U discloses "a portable fiber optic rotary connector with splicing function, including a fiber optic rotary connector body, a take-up mechanism, a housing, a fixing block, a through hole, a roller, a spring, a connecting wire, a splicing mechanism, and a rotating block. The beneficial effects of this invention are: the connecting wire passes through the roller and is wound around the roller, and the roller is rotatably connected to the housing, so rotating the roller facilitates the adjustment of the length of the connecting wire, which is beneficial for carrying the fiber optic rotary connector body and for organizing the connecting wire; one end of the connecting wire is fixed on the rotating block, and the connecting wire is rotatably connected to the fiber optic rotary connector body through the rotating block, thereby preventing the end of the connecting wire connected to the body from twisting when the roller is rotated; one end of the spring is fixed to the fiber optic rotary connector body, and the other end of the spring abuts against the end of the roller away from the fixing block, thereby facilitating the rotation of the roller, which is beneficial for the take-up and take-up of the connecting wire and for adjusting the length of the connecting wire."

[0004] While the aforementioned technologies allow for the storage and length adjustment of the connecting cable, adjusting its position requires continuous pressure on the fixing block to pull the cable on the roller. Furthermore, the exact length pulled cannot be determined during this adjustment, necessitating multiple pulls, which is cumbersome. Therefore, those skilled in the art have provided a rotatable MTP fiber optic connector to address the problems described in the background. Summary of the Invention

[0005] To address the cumbersome issue of requiring continuous pressing of a fixed block to pull the connecting cable on the roller when adjusting its position, and the inability to accurately determine the pulling length, necessitating multiple pulls to achieve the desired length, this invention provides a rotatable MTP fiber optic connector.

[0006] The present invention provides a rotatable MTP fiber optic connector with the following technical solution: a rotatable MTP fiber optic connector includes a fiber optic connector body, a housing fixedly connected to both the left and right sides of the fiber optic connector body, a rotating block rotatably connected to both the left and right sides of the fiber optic connector body, the rotating block being located inside the housing, a first connector fixedly connected to both the left and right sides of the fiber optic connector body, the first connector being located outside the rotating block, a take-up mechanism provided on the first connector, a connecting wire provided at one end of the rotating block, a positioning ring rotatably connected inside the housing, and a measuring mechanism provided on the outside of the fiber optic connector body.

[0007] Preferably, the take-up mechanism includes a take-up reel, a second connector, and a pressure block. The take-up reel is slidably connected to the first connector, and the connecting wire is wound on the take-up reel. The second connector is fixedly connected to the end of the take-up reel away from the first connector, and the pressure block is fixedly connected to the end of the second connector away from the first connector.

[0008] By adopting the above technical solution, the connecting wire can be stored by winding it around the take-up reel, and it is also convenient to adjust the length of the connecting wire.

[0009] Preferably, the measuring mechanism includes a scale, two indicator blocks, two sliding plates, and two elastic sleeves. The scale is fixedly connected to the outside of the fiber optic connector body. The two indicator blocks are slidably connected to the left and right sides of the scale, respectively. The two sliding plates are fixedly connected to the bottom of the corresponding indicator blocks, and the two elastic sleeves are fixedly connected to one end of the corresponding sliding plates.

[0010] By adopting the above technical solution, when adjusting the length of the connecting line, the connecting line can be pulled and locked onto the elastic sleeve. Then, by pushing the slide plate, the connecting line can be moved, causing the take-up reel to roll and release the connecting line. At this time, the user can accurately adjust the length of the connecting line by the sliding distance of the indicator block on the scale.

[0011] Preferably, a first magnet is fixedly connected to both the upper and lower ends of one side of the positioning ring, and a plurality of second magnets that cooperate with the first magnets are fixedly connected to one side of the take-up reel, wherein the second magnets and the first magnets are opposite magnets.

[0012] By adopting the above technical solution, when the take-up reel is moved by pressing the pressure block, and the second magnet on the take-up reel is attracted and attached to the first magnet on the positioning ring, the user can stop pressing the pressure block and directly pull the connecting line to make the take-up reel roll to release the line, which is more convenient.

[0013] Preferably, a first gear is fixedly connected to the outer side of the second connector, and a second gear that cooperates with the first gear is fixedly connected to the inside of the housing, and the first gear and the second gear mesh.

[0014] By adopting the above technical solution, when the length of the connecting line is not adjusted, the take-up reel will not rotate due to the cooperation of the first gear and the second gear, thus ensuring that the length of the connecting line does not easily change.

[0015] Preferably, the housing has limit grooves on both the left and right sides inside, and limit blocks are slidably connected in the limit grooves, with the end of the limit block away from the limit groove being fixedly connected to the second connector.

[0016] By adopting the above technical solution, during the process of pressing the pressure block to drive the take-up reel to move, the limiting block slides in the limiting groove, making the take-up reel more stable when moving.

[0017] Preferably, a spring is sleeved on the outer side of the first connector, and the left and right ends of the spring are respectively connected to the take-up reel and the optical fiber connector body.

[0018] By adopting the above technical solution, the spring is squeezed when the take-up reel moves. After the length of the connecting line is adjusted, the elastic force of the spring can drive the take-up reel back to the initial position, which makes it convenient to continue adjusting the length of the connecting line next time.

[0019] Preferably, the front of the housing has an opening, one end of the connecting wire passes through the opening, and a connector is fixedly connected to the end of the connecting wire that passes through the opening.

[0020] By adopting the above technical solution, the connector facilitates the connection between the connecting wire and external conductors.

[0021] Preferably, the optical fiber connector body has guide openings on both the left and right sides, and the slide plate is slidably connected to the guide openings.

[0022] By adopting the above technical solution, the guide opening makes the skateboard more stable during the movement of the connecting line as the skateboard moves.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The present invention is provided with a take-up mechanism, a spring and a first connector. By pressing the pressure block, the take-up reel moves, and then the first gear on the second connector moves away from the second gear inside the housing. At this time, the limitation on the take-up reel is removed, and the connecting line can be rolled by rotating the pressure block, so the length of the connecting line can be adjusted.

[0025] 2. The present invention also includes a positioning ring, a first magnet, and a second magnet. When adjusting the length of the connecting wire, pressing the second connector causes the take-up reel to move, which causes the second magnet on the take-up reel to adhere to the first magnet on the positioning ring. At this time, the user does not need to continue pressing the pressure block; the connecting wire can be pulled directly to adjust the length of the connecting wire, making the adjustment of the length of the connecting wire more convenient.

[0026] 3. The present invention also includes a measuring mechanism. When adjusting the length of the connecting line, the connecting line is directly clamped onto the elastic sleeve, and then the sliding plate can be used to pull the connecting line. By observing the distance the indicator block slides on the scale, the pulling length of the connecting line can be precisely controlled, which further improves the convenience of adjusting the length of the connecting line.

[0027] 4. The present invention also provides that the inner left and right sides of the shell are provided with limiting grooves, and limiting blocks are slidably connected in the limiting grooves. The end of the limiting block away from the limiting groove is fixedly connected to the second connector. When the pressing block drives the take-up reel to move, the sliding of the limiting block in the limiting groove makes the take-up reel more stable when moving.

[0028] 5. The present invention also provides a spring sleeved on the outer side of the first connector. The left and right ends of the spring are respectively connected to the take-up reel and the fiber optic connector body. When the take-up reel moves, it will squeeze the spring. After the length of the connecting line is adjusted, the elastic force of the spring can drive the take-up reel back to the initial position, which makes it convenient to continue to adjust the length of the connecting line next time.

[0029] 6. The present invention also provides guide openings on both the left and right sides of the fiber optic connector body, and the slide plate is slidably connected to the guide openings. During the process of the slide plate moving and pulling the connecting line, the guide openings make the slide plate more stable when moving. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This invention discloses a rotatable MTP fiber optic connector. (Refer to...) Figure 1-8 A rotatable MTP fiber optic connector includes a fiber optic connector body 1, a housing 2 fixedly connected to both the left and right sides of the fiber optic connector body 1, a rotating block 3 rotatably connected to both the left and right sides of the fiber optic connector body 1, with the rotating block 3 located inside the housing 2, a first connector 4 fixedly connected to both the left and right sides of the fiber optic connector body 1, with the first connector 4 located outside the rotating block 3, a take-up mechanism 5 provided on the first connector 4, a connecting line 6 provided at one end of the rotating block 3, a positioning ring 7 rotatably connected inside the housing 2, and a measuring mechanism 8 provided on the outside of the fiber optic connector body 1.

[0041] Reference Figure 2The take-up mechanism 5 includes a take-up reel 501, a second connector 502, and a pressure block 503. The take-up reel 501 is slidably connected to the first connector 4, and the connecting wire 6 is wound around the take-up reel 501. The second connector 502 is fixedly connected to the end of the take-up reel 501 away from the first connector 4, and the pressure block 503 is fixedly connected to the end of the second connector 502 away from the first connector 4. By adopting the above technical solution, the connecting wire 6 can be stored by winding it around the take-up reel 501, and it is also convenient to adjust the length of the connecting wire 6.

[0042] Reference Figure 7 The measuring mechanism 8 includes a scale 801, two indicator blocks 802, two sliding plates 803, and two elastic sleeves 804. The scale 801 is fixedly connected to the outside of the fiber optic connector body 1. The two indicator blocks 802 are slidably connected to the left and right sides of the scale 801, respectively. The two sliding plates 803 are fixedly connected to the bottom of the corresponding indicator blocks 802, respectively. The two elastic sleeves 804 are fixedly connected to one end of the corresponding sliding plates 803, respectively. By adopting the above technical solution, when adjusting the length of the connecting cable 6, the connecting cable 6 can be pulled and made to lock onto the elastic sleeve 804. Then, by pushing the sliding plate 803, the connecting cable 6 can be moved, causing the take-up reel 501 to roll and release the connecting cable 6. At this time, the user can accurately adjust the length of the connecting cable 6 by the sliding distance of the indicator blocks 802 on the scale 801.

[0043] Reference Figure 3 The positioning ring 7 has a first magnet 9 fixedly connected to both the upper and lower ends on one side, and a number of second magnets 10 that cooperate with the first magnet 9 are fixedly connected to one side of the take-up reel 501. The second magnets 10 and the first magnet 9 are opposite magnets. By adopting the above technical solution, when the take-up reel 501 is moved by pressing the pressure block 503, when the second magnet 10 on the take-up reel 501 is attracted and attached to the first magnet 9 on the positioning ring 7, the user can stop pressing the pressure block 503 and directly pull the connecting line 6 to make the take-up reel 501 roll to release the line, which is more convenient.

[0044] Reference Figure 5 The outer side of the second connector 502 is fixedly connected to the first gear 11, and the inner side of the housing 2 is fixedly connected to the second gear 12 that works with the first gear 11, and the first gear 11 and the second gear 12 mesh. By adopting the above technical solution, when the length of the connecting line 6 is not adjusted, the engagement of the first gear 11 and the second gear 12 ensures that the take-up reel 501 will not rotate, thus ensuring that the length of the connecting line 6 does not easily change.

[0045] Reference Figure 2The housing 2 has limit grooves 13 on both the left and right sides inside. Limit blocks 14 are slidably connected in the limit grooves 13, and the end of the limit block 14 away from the limit groove 13 is fixedly connected to the second connector 502. By adopting the above technical solution, when the pressing block 503 drives the take-up reel 501 to move, the limit block 14 slides in the limit groove 13, making the take-up reel 501 more stable when moving.

[0046] Reference Figure 2 A spring 15 is sleeved on the outer side of the first connector 4. The left and right ends of the spring 15 are connected to the take-up reel 501 and the fiber optic connector body 1, respectively. By adopting the above technical solution, the spring 15 will be squeezed when the take-up reel 501 moves. After the length of the connecting line 6 is adjusted, the elastic force of the spring 15 can drive the take-up reel 501 back to the initial position, which makes it convenient to continue to adjust the length of the connecting line 6 next time.

[0047] Reference Figure 1 The front of the housing 2 has an opening 16, one end of the connecting wire 6 passes through the opening 16, and the end of the connecting wire 6 passing through the opening 16 is fixedly connected to the connector 17; by adopting the above technical solution, the connector 17 facilitates the connection of the connecting wire 6 to the external wire.

[0048] Reference Figure 8 The fiber optic connector body 1 has guide ports 18 on both the left and right sides, and the slide plate 803 is slidably connected to the guide ports 18. By adopting the above technical solution, the slide plate 803 is more stable when moving as it pulls the connecting line 6.

[0049] Working principle: In use, all electrical components described in this application are externally connected to a power source and control switch. When the length of the connecting cable 6 needs to be adjusted, the pressure block 503 is pressed to move the second connector 502. The movement of the second connector 502 moves the take-up reel 501 and simultaneously moves the first gear 11 away from the second gear 12, thus eliminating the limiting and fixing of the second connector 502. When the take-up reel 501 moves, it causes the second magnet 10 to adhere to the first magnet 9 on the positioning ring 7. The operator can stop pressing the pressure block 503. At this time, the operator can pull the connecting line 6 and make the connecting line 6 lock on the elastic sleeve 804. Then, by pushing the slide plate 803, the connecting line 6 can be moved, which causes the take-up reel 501 to roll and release the connecting line 6. The rotating block 3 ensures that the connecting line 6 will not twist during the release. At this time, the operator can accurately adjust the length of the connecting line 6 by sliding the indicator block 802 on the scale 801, making the adjustment of the length of the connecting line 6 more convenient.

[0050] When using this invention, it is not only convenient to adjust the length of the connecting line 6, but also allows for precise adjustment of the connecting line 6 without the need for repeated adjustments.
