Description

Technical Field

[0001] The utility model relates to the technical field of combined pigtail devices, in particular to a 12-core bundle combined pigtail. Background Technique

[0002] A pigtail has a connector at only one end and an optical fiber at the other end, which is connected to other optical fibers by fusion splicing and is commonly used to connect an optical fiber and a transceiver. The utility model patent with the patent application number CN202321061862.6 discloses an anti-breakage reinforced pigtail for electronic devices. By moving two semi-circular unit shells towards the end of the pigtail body with a ceramic ferrule, after the two semi-circular unit shells are combined, they are fastened through connecting ears and bolts. Then, the combination of two semi-circular combined sliding rings and the steel balls inside them form a first sliding sleeve, and the combination of another two semi-circular combined sliding rings and the steel balls inside them form a second sliding sleeve, so that the two semi-circular unit shells cover the periphery of the ceramic ferrule and form a protective shell, enabling the fixing sleeve of the pigtail body to rotate with the second sliding sleeve, and the ceramic ferrule to rotate with the first sliding sleeve. Compared with the existing anti-breakage structure of the pigtail, the rotational friction resistance is small, greatly alleviating the situation of the pigtail breaking under the twisting state. According to the disclosed technical solution, when the existing combined pigtail device is in use, on the one hand, when connecting to a transceiver, it is easy to loosen between the pigtail and the transceiver due to factors such as pulling and vibration, which is not conducive to ensuring the connection firmness. On the other hand, when using the locking mechanism to lock the transceiver and the pigtail, it is easy for the pigtail to be damaged due to a large pulling force on the pigtail, which is not conducive to ensuring the safety of the pigtail.

[0003] Therefore, how to design a 12-core bundle combined pigtail has become the problem we need to solve currently. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a 12-core bundle combined pigtail to solve the problems raised in the above background technique. The utility model is reasonably designed and is more convenient to use, suitable for the connection and use of optical fibers and devices.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A 12-core bundle combined pigtail includes a pigtail and a 12-core bundle optical fiber. A connection component is installed on the pigtail, and the connection component includes an insertion plate and a connector. An activity component is installed inside the pigtail, and the activity component includes an inner groove and a rotating plate. A locking component is installed at one end of the rotating plate, and the locking component includes a baffle plate and a pin. A limiting component is installed on the insertion plate and the pin, and the limiting component includes a groove and a stop block. A pressing component is installed on the rotating plate, and the pressing component includes a connecting rod and a pressing plate.

[0006] Further, one end of the 12-core bundle optical fiber is connected to one end of the pigtail, the patch panel is integrally formed at the other end of the pigtail, and the connector is installed inside the patch panel.

[0007] Further, the inner grooves are respectively formed inside the pigtail and the patch panel, the groove is formed inside the patch panel, and the groove communicates with the inner groove.

[0008] Further, one end of the baffle is integrally formed on one end of the rotating plate, one end of the latch is bonded to the other end of the baffle, and the other end of the latch passes through the inner groove and extends to the outside of the patch panel.

[0009] Further, the stopper is integrally formed on one side of the latch, and the stopper is stuck on the inner wall of the inner groove.

[0010] Further, the other end of the rotating plate is installed inside the inner groove through a rotating shaft, and the rotating plate is connected to the inner wall of the inner groove through a spring.

[0011] Further, one end of the connecting rod is welded to the rotating plate, and the other end of the connecting rod passes through the inner groove and extends to the outside of the pigtail.

[0012] Further, the pressing plate is welded to the other end of the connecting rod, and the latch and the rotating plate are respectively installed on the top and bottom of the patch panel and the pigtail.

[0013] Beneficial effects: 1. When the 12-core bundle pigtail is in use, the 12-core bundle optical fiber is connected to the optical cable by fusion splicing, and then the patch panel and the connector on the pigtail are inserted into the interface of the transceiver. The spring in the inner groove pushes the rotating plate, and the rotating plate drives the baffle and the latch to be inserted into the interface of the transceiver, thereby locking the pigtail, avoiding loosening of the connector and the interface of the transceiver caused by pulling and vibration of the pigtail, ensuring the connection firmness, and effectively ensuring the signal transmission stability.

[0014] 2. When the 12-core bundle pigtail is in use and needs to be disassembled, squeeze the pressing plate. The pressing plate pushes the rotating plate through the connecting rod. The rotating plate compresses the spring and drives the baffle and the latch to move to the inside of the inner groove, and then the patch panel and the connector can be pulled out. If the operator forgets to squeeze the pressing plate, or the pigtail is subjected to too much pulling force, the bonding surface of the latch and the baffle will be separated due to excessive external force, so that the latch drives the stopper to move leftward from the inside of the groove, and the pigtail together with the patch panel and the connector is removed from the interface, avoiding damage to the pigtail and ensuring the safety of the pigtail. The spring pushes the rotating plate, so that the rotating plate drives the baffle to move to the outside of the patch panel, and the baffle can still lock the patch panel through the baffle, ensuring the subsequent connection and fixing work of the pigtail.

[0015] 3. The 12-core bundle pigtail is reasonably designed, efficient and convenient to use, and is suitable for the connection and use of optical fibers and equipment. Brief Description of the Drawings

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a 12-core bundle pigtail, including a pigtail 1 and a 12-core bundle optical fiber 2. A connection component is installed on the pigtail 1. The connection component includes a plug board 3 and a connector 4. An active component is installed inside the pigtail 1. The active component includes an inner groove 5 and a rotating plate 6. A locking component is installed at one end of the rotating plate 6. The locking component includes a baffle 9 and a pin 10. A limiting component is installed on the plug board 3 and the pin 10. The limiting component includes a groove 8 and a stop block 11. A pressing component is installed on the rotating plate 6. The pressing component includes a connecting rod 12 and a pressing plate 13. The inner grooves 5 are respectively opened inside the pigtail 1 and the plug board 3. The groove 8 is opened inside the plug board 3. The groove 8 communicates with the inner groove 5. One end of the baffle 9 is integrally formed on one end of the rotating plate 6. One end of the pin 10 is bonded to the other end of the baffle 9. The other end of the pin 10 passes through the inner groove 5 and extends to the outside of the plug board 3. During use, the 12-core bundle optical fiber 2 is connected to the optical cable by fusion splicing. Then, the plug board 3 and the connector 4 on the pigtail 1 are inserted into the interface of the transceiver. The spring 7 inside the inner groove 5 pushes the rotating plate 6. The rotating plate 6 drives the baffle 9 and the pin 10 to be inserted into the interface of the transceiver, thereby locking the pigtail 1, preventing the pigtail 1 from loosening the connector 4 and the interface of the transceiver due to pulling and vibration, ensuring the connection firmness, and effectively ensuring the signal transmission stability.

[0022] In this embodiment, one end of the 12-core bundle optical fiber 2 is connected to one end of the pigtail 1. The plug board 3 is integrally formed at the other end of the pigtail 1. The connector 4 is installed inside the plug board 3. The stop block 11 is integrally formed on one side of the pin 10. The stop block 11 is stuck on the inner wall of the inner groove 5. The other end of the rotating plate 6 is installed inside the inner groove 5 through a rotating shaft. The rotating plate 6 is connected to the inner wall of the inner groove 5 by a spring 7. One end of the connecting rod 12 is welded to the rotating plate 6. The other end of the connecting rod 12 passes through the inner groove 5 and extends to the outside of the pigtail 1. The pressing plate 13 is welded to the other end of the connecting rod 12. The pin 10 and the rotating plate 6 are respectively installed at the top and bottom of the plug board 3 and the pigtail 1. When the pigtail 1 needs to be disassembled, the pressing plate 13 is squeezed. The pressing plate 13 pushes the rotating plate 6 through the connecting rod 12. The rotating plate 6 compresses the spring 7 and drives the baffle 9 and the pin 10 to move to the inside of the inner groove 5, and then the plug board 3 and the connector 4 can be pulled out. If the operator forgets to squeeze the pressing plate 13, or when the pigtail 1 is subjected to excessive pulling force, the bonding surface between the pin 10 and the baffle 9 is separated due to excessive external force. As a result, the pin 10 drives the stop block 11 to move leftward from the inside of the groove 8, and the pigtail 1 together with the plug board 3 and the connector 4 is removed from the interface, avoiding damage to the pigtail 1 and ensuring the safety of the pigtail 1. The spring 7 pushes the rotating plate 6, so that the rotating plate 6 drives the baffle 9 to move to the outside of the plug board 3. The plug board 3 can still be locked by the baffle 9, ensuring the subsequent connection and fixing work of the pigtail 1.

[0023] When the 12-core fiber optic ribbon pigtail is in use, the 12-core fiber optic ribbon 2 is connected to the optical cable by fusion splicing. Then, the plug board 3 and the connector 4 on the pigtail 1 are inserted into the interface of the transceiver. The spring 7 in the inner groove 5 pushes the rotating plate 6, and the rotating plate 6 drives the baffle 9 and the latch 10 to be inserted into the interface of the transceiver, thereby locking the pigtail 1, avoiding loosening of the connector 4 and the interface of the transceiver caused by pulling and vibration of the pigtail 1, ensuring the connection firmness, and effectively ensuring the signal transmission stability. When the pigtail 1 needs to be disassembled, the pressure plate 13 is squeezed. The pressure plate 13 pushes the rotating plate 6 through the connecting rod 12. The rotating plate 6 compresses the spring 7 and drives the baffle 9 and the latch 10 to move to the inner side of the inner groove 5, and then the plug board 3 and the connector 4 can be pulled out. If the operator forgets to squeeze the pressure plate 13, or when the pigtail 1 is subjected to too much tensile force, the bonding surface between the latch 10 and the baffle 9 is separated due to excessive external force, and then the latch 10 drives the stopper 11 to move leftward from the inner side of the groove 8, and the pigtail 1 together with the plug board 3 and the connector 4 is removed from the interface, avoiding damage to the pigtail 1 and ensuring the safety of the pigtail 1. The spring 7 pushes the rotating plate 6, so that the rotating plate 6 drives the baffle 9 to move to the outside of the plug board 3, and the plug board 3 can still be locked by the baffle 9, ensuring the subsequent connection and fixing work of the pigtail 1.
