Description

Technical Field

[0001] The utility model relates to the field of optical fibers, in particular to an auxiliary installation device for optical fiber terminals. Background Art

[0002] There are multiple terminal connection ports in the optical fiber connector, which can be set to 8, 16, 32, 40 or even more according to needs. Larger optical fibers may even require hundreds of terminals to be connected. During each installation, workers need to pull the terminal interface into the outer shell of the connector and connect the terminals one by one to the corresponding interfaces.

[0003] The applicant believes that there are multiple terminal interfaces in the optical fiber connector. When connecting the terminals, the outer shell of the connector needs to be removed for connection and is easily restricted by the outer shell of the connector. In addition, workers are prone to damage other components when connecting the terminals, making it difficult to connect the terminals smoothly. Utility Model Content

[0004] In order to make it more convenient for workers to connect terminals, the utility model provides an auxiliary installation device for optical fiber terminals.

[0005] The utility model provides an auxiliary installation device for optical fiber terminals, which adopts the following technical solutions:

[0007] When it is necessary to connect the optical fiber terminal, the fixing restriction of the locking piece on the cover plate is released, and then force is applied to the pull plate to make the pull plate slide from the side hole to the outside of the shell. The worker can then connect the terminal on the outside of the shell to avoid entering the shell to connect, which may cause difficult alignment or loose connection, making the connection operation convenient and faster.

[0008] Preferably, side plates are provided on both sides of the pull plate, the side plates are perpendicular to the cover plate, and the side plates are in abutment with the inner side walls of the shell.

[0009] The side plates on both sides are fitted against the inner wall of the shell, so that the pull plate is not easy to shake when being pulled, which can improve the smoothness of the pull plate sliding, and at the same time make it easier to pull the pull plate out of the shell, making it easier to connect the terminals. At the same time, it is difficult for the pull plate installed in the shell to shake, which is conducive to improving the stability of the terminal connection installation.

[0010] Preferably, the side plate is provided with a sliding member, the inner side wall of the shell is provided with a sliding rail for the sliding member to slide, the sliding member is snap-fitted and slides in the sliding rail, and an end of the sliding rail close to the cover plate is opened and communicated with the side hole.

[0011] When the terminal needs to be connected, pull the pull plate to make the sliding part slide in the slide rail so that the terminal interface on the pull plate is pulled out of the shell. After the terminal connection is completed, insert the sliding part into the slide rail from the open end of the slide rail. The slide rail can guide the sliding of the pull plate, so that the pull plate is more firmly installed in the shell.

[0012] Preferably, the slide rail includes a limiting upper end and a limiting lower end, and the limiting upper end and the limiting lower end are respectively clamped with the limiting sliding member from both sides in the length direction of the slide rail, and the side wall of the sliding member is integrally connected with an upper clamping member and a lower clamping member, the upper clamping member is arranged close to the limiting upper end, and the lower clamping member is arranged close to the limiting lower end, the limiting upper end is clamped between the upper clamping member and the sliding member, and the limiting lower end is clamped between the lower clamping member and the sliding member.

[0013] The sliding member and the sliding rail are mutually clamped and restricted, making the connection between the sliding member and the sliding rail tighter and the structural coordination between the sliding member and the sliding rail more compact, further improving the stability of the pull plate in the outer shell, making it more difficult for the pull plate and the outer shell to move relative to each other, which is beneficial to improving the stability of the optical fiber connection.

[0014] Preferably, the cover plate is rotatably connected to the outer shell.

[0015] The cover is not completely separated from the housing, which reduces the trouble of removal and avoids the cover being lost or the connected components being lost when the cover is opened.

[0016] Preferably, the locking member includes a supporting member and an elastic member arranged on the side wall of the cover plate, an insert block is slidably connected inside the supporting member, one side of the insert block is fixedly connected to the elastic member, the outer shell is provided with an insert hole, when the cover plate is covered with the side hole, the side of the insert block away from the elastic member is inserted into the insert hole, the insert block is provided with a force applying portion, and the force applying portion is located on the side of the cover plate away from the outer shell.

[0017] When opening the cover, the force-applying part outside the shell is operated to apply force to the force-applying part, thereby driving the plug block to move in a direction away from the socket, so that the plug block is separated from the socket, thereby releasing the movement restriction of the cover by the plug block, so that the cover can be opened without the restriction of the locking member.

[0018] Preferably, the force-applying portion is recessed with an arc-shaped groove toward the force-applying direction for facilitating force application.

[0019] When applying force, place the finger in the arc groove to prevent the finger from sliding along the surface of the force-applying part, resulting in unconcentrated force, making the cover easier to open.

[0020] Preferably, a pull ring is provided on the pull plate.

[0021] The setting of the pull ring provides the pull plate with a clearer force application point, making it easier for the pull plate to slide out of the housing.

[0022] Preferably, a positioning piece is provided in the shell, and when the pull plate is located in the shell, one end of the pull plate away from the cover plate abuts against the positioning piece, and one end of the pull plate away from the positioning piece abuts against the cover plate.

[0023] The cover plate cooperates with the positioning piece to press against the two ends of the pull plate, so that the movement of the pull plate is restricted all around, which is beneficial to further improve the stability of the pull plate installed in the shell.

[0024] In summary, the utility model includes the following beneficial technical effects:

[0025] When it is necessary to connect the optical fiber terminal, the fixing restriction of the locking piece on the cover plate is released, and then force is applied to the pull plate to make the pull plate slide from the side hole to the outside of the shell. The worker can then connect the terminal on the outside of the shell to avoid entering the shell to connect, which may cause difficult alignment or loose connection, making the connection operation convenient and faster.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 The utility model is described in further detail.

[0031] The utility model embodiment discloses an auxiliary installation device for an optical fiber terminal.

[0032] Reference Figure 1 as well as Figure 2 , an auxiliary installation device for an optical fiber terminal, comprising a pull plate 2 arranged in a shell 1, a connection port 3 of the optical fiber terminal arranged on the pull plate 2, a side hole 8 is opened in the shell 1 for the pull plate 2 to slide out, the side hole 8 is covered with a cover plate 4, and the shell 1 is provided with a locking member for fixing the cover plate 4.

[0033] When it is necessary to connect the optical fiber terminal, the fixing restriction of the locking piece on the cover plate 4 is released, and then force is applied to the pull plate 2 to make the pull plate 2 slide from the side hole 8 to the outside of the housing 1. The worker can then perform the connection operation on the terminal outside the housing 1, avoiding entering the inside of the housing 1 to perform the connection, which may cause difficulty in alignment or loose connection, making the connection operation convenient and faster.

[0034] Reference Figure 2 as well as Figure 3 In this embodiment, side plates 5 are provided on both sides of the pull plate 2 , the side plates 5 are perpendicular to the cover plate 4 , and the side plates 5 are in contact with the inner side wall of the shell 1 .

[0035] The side plates 5 on both sides are in close contact with the inner side wall of the housing 1, so that the pull plate 2 is not easy to shake when being pulled, which can improve the smoothness of the sliding of the pull plate 2, and at the same time make it easier to pull the pull plate 2 out of the housing 1, making it easier to connect the terminals. At the same time, the pull plate 2 installed in the housing 1 is not easy to shake, which is conducive to improving the stability of the terminal connection installation.

[0036] Reference Figure 2 as well as Figure 3 In this embodiment, the side plate 5 is provided with a sliding member 6, and the inner wall of the shell 1 is provided with a slide rail 7 for the sliding member 6 to slide. The sliding member 6 is snap-fitted and slides in the slide rail 7, and the end of the slide rail 7 close to the cover plate 4 is opened and connected to the side hole 8.

[0037] When the terminal needs to be connected, pull the pull plate 2 so that the sliding member 6 slides in the slide rail 7 so that the terminal interface on the pull plate 2 is pulled out of the housing 1. After the terminal connection is completed, insert the sliding member 6 from the open end of the slide rail 7 into the slide rail 7. The slide rail 7 can guide the sliding of the pull plate 2, so that the pull plate 2 is more firmly installed in the housing 1.

[0038] Reference Figure 2 as well as Figure 3 In the present embodiment, the slide rail 7 comprises a limiting upper end 9 and a limiting lower end 10, which respectively clamp the limiting sliding member 6 from both sides in the length direction of the slide rail 7, and the side wall of the sliding member 6 is integrally connected with an upper clamping member 11 and a lower clamping member 12, the upper clamping member 11 is arranged close to the limiting upper end 9, and the lower clamping member 12 is arranged close to the limiting lower end 10, the limiting upper end 9 is clamped between the upper clamping member 11 and the sliding member 6, and the limiting lower end 10 is clamped between the lower clamping member 12 and the sliding member 6.

[0039] The sliding member 6 and the sliding rail 7 are mutually clamped and restricted, so that the connection between the sliding member 6 and the sliding rail 7 is tighter, and the structural coordination between the sliding member 6 and the sliding rail 7 is more compact, which further improves the stability of the pull plate 2 in the outer shell 1, making it more difficult for the pull plate 2 and the outer shell 1 to move relative to each other, which is beneficial to improving the stability of the optical fiber connection.

[0040] The slide rail 7 is fixedly connected to the inside of the shell 1 by multiple screws. When the slide rail 7 is deformed due to long-term use, which makes it difficult for the sliding member 6 to slide smoothly, the slide rail 7 can be removed and replaced with a new one, avoiding the situation where the entire shell 1 needs to be replaced, which is beneficial to reducing maintenance costs.

[0041] The top of the housing 1 is provided with a detachable connection through various means such as connecting pins. When replacing the slide rail 7, the top of the housing 1 can be opened, and the pull plate 2 and the terminal connector can be taken out for replacement, which is convenient and quick.

[0042] Reference Figure 2 as well as Figure 3 In this embodiment, the cover plate 4 is rotatably connected to the housing 1 .

[0043] The cover plate 4 is in an incompletely separated state from the housing 1 , which reduces the trouble of removal and avoids the cover plate 4 being lost or the connected components being lost when the cover plate 4 is opened.

[0044] The connection between the cover plate 4 and the housing 1 can be a hinge 19 connection, or other connection methods such as a pin connection. In this embodiment, the cover plate 4 is provided with two hinges 19 for rotationally connecting with the bottom wall of the housing 1.

[0045] Reference Figure 2 as well as Figure 3 In this embodiment, the locking member includes a support member 13 and an elastic member arranged on the side wall of the cover plate 4. An insert block 14 is slidably connected inside the support member 13. One side of the insert block 14 is fixedly connected to the elastic member. The housing 1 is provided with a plug hole 15. When the cover plate 4 is covered on the side hole 8, the side of the insert block 14 away from the elastic member is inserted into the plug hole 15. The insert block 14 is provided with a force applying portion 16, and the force applying portion 16 is located on the side of the cover plate 4 away from the housing 1.

[0046] When opening the cover 4, the force-applying portion 16 outside the housing 1 is operated to apply force to the force-applying portion 16, thereby driving the plug 14 to move in a direction away from the insertion hole 15, so that the plug 14 is separated from the insertion hole 15, thereby releasing the movement restriction of the plug 14 on the cover 4, so that the cover 4 can be freed from the restriction of the locking member and opened.

[0047] In this embodiment, the insertion hole 15 is arranged at the top of the housing 1 , and two groups of locking members are arranged. The two groups of locking members are evenly distributed along the length direction of the cover plate 4 .

[0048] In other embodiments, the jack 15 may also be disposed on the side wall or the bottom wall of the housing 1 , and the plug block 14 may be adaptively disposed corresponding to the jack 15 .

[0049] Reference Figure 2 as well as Figure 3 In this embodiment, the force applying portion 16 is recessed toward the force applying direction to form an arc-shaped groove for facilitating force application.

[0050] When applying force, the fingers are placed in the arc groove to prevent the fingers from sliding along the surface of the force applying portion 16 to cause the force to be not concentrated, so that the cover plate 4 is easier to open.

[0051] Reference Figure 2 as well as Figure 3 In this embodiment, a pull ring 17 is provided on the pull plate 2.

[0052] The provision of the pull ring 17 provides the pull plate 2 with a more definite force application point, making it easier for the pull plate 2 to slide out of the housing 1 .

[0053] In this embodiment, a plurality of pull rings 17 are provided, and the plurality of pull rings 17 are evenly distributed along the length direction of the cover plate 4 .

[0054] Reference Figure 2 as well as Figure 3 In this embodiment, a positioning member 18 is provided in the housing 1. When the pull plate 2 is located in the housing 1, one end of the pull plate 2 away from the cover plate 4 abuts against the positioning member 18, and the other end of the pull plate 2 away from the positioning member 18 abuts against the cover plate 4.

[0055] The cover plate 4 cooperates with the positioning member 18 to press against the two ends of the pull plate 2 , so that the movement of the pull plate 2 is restricted all around, which is beneficial to further improve the stability of the pull plate 2 installed in the housing 1 .

[0056] In this embodiment, the length of the pull plate 2 is extended so that the pull plate 2 abuts against the outside of a component in the housing 1 to achieve positioning, and the base of the component is used as the positioning member 18, thereby simplifying the overall device.

[0057] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
