Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing technology, and in particular to a plug-in / plug-out fixture. Background Technology

[0002] As a communication device, fiber optic cables require plugging and unplugging when used in scenarios such as switch maintenance. Previously, this was done manually. For example, when connecting 256 fibers to a switch, manually plugging and unplugging each fiber individually would take approximately 10 minutes, which was cumbersome and time-consuming. While current technologies that connect two fibers in parallel can reduce the number of plugging and unplugging operations by half, the process remains inconvenient and inefficient. Utility Model Content

[0003] This application discloses a insertion and removal fixture, which can significantly improve the insertion and removal efficiency of the parts to be inserted or removed, and has a simple and reliable structure.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] This application provides a insertion / removal fixture for assisting in the insertion and removal of multiple components, including:

[0006] Fixture body;

[0007] A grille is disposed at one end of the fixture body, and the grille includes a plurality of slots arranged along a first direction for clamping the plurality of insertable and removable parts;

[0008] Multiple drive levers are rotatably connected to the fixture body. Each drive lever includes a drive part and an unlocking part. The unlocking part is correspondingly disposed with at least one of the slots. The drive part is used to drive the unlocking part to press the insert / remove part along a second direction. The second direction is perpendicular to the first direction and perpendicular to the axial direction of the slot.

[0009] The aforementioned insertion / removal fixture can be used to insert and remove multiple components. Specifically, the insertion / removal fixture of this application includes a fixture body, a grille, and multiple drive levers. The fixture body has a receiving cavity for accommodating multiple components. The grille covers one end of the receiving cavity of the fixture body and includes multiple slots arranged along a first direction, each slot for clamping one component. Multiple drive levers are rotatably connected to the fixture body, each drive lever including a drive part and an unlocking part, the unlocking part corresponding to at least one of the slots. The drive part is used to drive the unlocking part to press the component to be inserted / removed along a second direction to unlock the component. In the application of the insertion / removal fixture, multiple slots of the fixture hold multiple components to be inserted or removed, such as the plug portion of an LC-type optical fiber. The latches of the components in the slots corresponding to the unlocking part engage with the unlocking part, while the latches of the components in slots not corresponding to the unlocking part engage with the fixture body, and these latches are always in a pressed state. Alternatively, the components in slots not corresponding to the unlocking part may not have a latch structure, allowing multiple components to be inserted into the device at the same time, such as into a switch. When multiple components need to be removed, the driving part can be pressed manually or with the aid of other tools along a second direction. This causes the driving part to drive the unlocking part to press the latches of at least one component along the second direction, thereby unlocking the latch of at least one component. Next, the insertion / removal fixture is pulled outwards. Under the pulling force, friction is generated between the unlocking part and the latch, and friction is also generated between the fixture body and other latches. Under the action of friction, the unlocking part and the fixture body will move the parts to be inserted / removed out of the device to be used, thus completing the removal of multiple parts to be inserted / removed. The insertion / removal fixture of this application can complete the insertion / removal of multiple parts to be inserted / removed simultaneously, which can significantly improve the insertion / removal efficiency of parts to be inserted / removed, and has fewer components and a simple and reliable structure.

[0010] In some embodiments, the inner wall of the slot of the grille is provided with a limiting portion for limiting the insertion / removal of the component along the axial direction of the slot.

[0011] In some embodiments, the fixture body includes opposing first and second plates, and the grid is connected between the first and second plates;

[0012] The driving part and unlocking part of each driving lever are located on the side of the first plate opposite to the second plate and the side of the second plate opposite to the first plate, respectively.

[0013] The first plate is provided with a first lever assembly; and / or the second plate is provided with a second lever assembly, wherein both the first lever assembly and the second lever assembly include a plurality of the drive levers.

[0014] In some embodiments, the insertion and removal fixture further includes a rotating shaft, and a drive lever connected to the first plate and a drive lever connected to the second plate are rotatably connected via the rotating shaft.

[0015] In some embodiments, the plurality of drive levers are respectively disposed corresponding to the plurality of slots located at the ends.

[0016] In some embodiments, the slot includes a first slot, which does not correspond to the unlocking part;

[0017] The first plate has a plurality of first protrusions on the side facing the grille, with one first protrusion corresponding to one first slot; and / or, the second plate has a plurality of second protrusions on the side facing the grille, with one second protrusion corresponding to one first slot.

[0018] In some embodiments, the unlocking part has a third protrusion at one end near the slot.

[0019] In some embodiments, the third protrusion is provided with a wear-resistant layer.

[0020] In some embodiments, in each of the drive levers, the length ratio of the drive portion to the unlocking portion is 1:3 to 1:5.

[0021] In some embodiments, the fixture body is integrally formed with the grille. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0032] like Figures 1-7 As shown, this application embodiment provides a insertion / removal fixture for assisting in the insertion and removal of multiple components 01 to be inserted or removed, including:

[0033] Fixture body 1;

[0034] A grille 2 is disposed at one end of the fixture body 1. The grille 2 includes a plurality of slots 21 arranged along a first direction for clamping a plurality of insertable / removable parts 01.

[0035] Multiple drive levers 3 are rotatably connected to the fixture body 1. Each drive lever 3 includes a drive part 31 and an unlocking part 32. The unlocking part 32 is correspondingly disposed with at least one slot 21. The drive part 31 is used to drive the unlocking part 32 to press the insert / remove part 01 along a second direction. The second direction is perpendicular to the first direction and perpendicular to the axial direction of the slot 21.

[0036] The aforementioned insertion / removal fixture can be used to insert and remove multiple components 01. Specifically, the insertion / removal fixture of this application includes a fixture body 1, a grille 2, and multiple drive levers 3. The fixture body 1 has a receiving cavity for accommodating multiple components 01. The grille 2 covers one end of the receiving cavity of the fixture body 1, and the grille 2 includes multiple slots 21 arranged along a first direction. Each slot 21 is used to clamp one component 01. The multiple drive levers 3 are rotatably connected to the fixture body 1. Each drive lever 3 includes a drive part 31 and an unlocking part 32. The unlocking part 32 is correspondingly disposed with at least one slot 21. The drive part 31 is used to drive the unlocking part 32 to press the component 01 to be inserted / removed along a second direction to unlock the component 01.

[0037] like Figures 1-3 As shown, during the application of the insertion / removal fixture, multiple slots 21 of the fixture clamp multiple components 01 to be inserted / removed, such as the plug portion of an LC-type optical fiber. The latches 011 of the components 01 to be inserted / removed in the slots 21 corresponding to the unlocking part 32 engage with the unlocking part 32. The latches 011 of the components 01 to be inserted / removed in the slots 21 not corresponding to the unlocking part 32 engage with the fixture body 1, and the latches 011 are always in a pressed state. Of course, the components 01 to be inserted / removed in the slots 21 not corresponding to the unlocking part 32 may not have a latch 011 structure, allowing multiple components 01 to be inserted / removed together into the device to be used, such as a switch. When it is necessary to remove multiple components 01, the driving part 31 can be pressed manually or with the aid of other tools along the second direction, causing the driving part 31 to drive the unlocking part 32 to press the latches 011 of the components 01 to be inserted / removed along the second direction, thereby unlocking the latches 011 of at least one component 01. Next, the insertion and removal fixture is pulled outward. Under the action of the pulling force, friction will be generated between the unlocking part 32 and the buckle 011. Friction will also be generated between the fixture body 1 and other buckles 011. Under the action of the friction, the unlocking part 32 and the fixture body 1 will drive the insertion and removal parts 01 to be removed out of the device to be used, and finally the removal of multiple insertion and removal parts 01 is completed.

[0038] The insertion and removal fixture of this application can simultaneously insert and remove multiple parts 01 to be inserted or removed, which can greatly improve the insertion and removal efficiency of the parts 01 to be inserted or removed, and has a small number of components and a simple and reliable structure.

[0039] It should be noted that the driving part 31 and the unlocking part 32 of the driving lever 3 in the embodiments of this application can be an integral structure, and mechanical linkage is achieved by lever principle.

[0040] In some embodiments, the inner wall of the slot 21 of the grille 2 is provided with a limiting part 22 for limiting the insertion / removal member 01 along the axial direction of the slot 21.

[0041] One possible way to achieve this is, such as Figure 4As shown, the grille 2 is designed with multiple slots 21, which can limit the insertion and removal of multiple parts 01 in the first direction. A limiting part 22 is provided on the inner wall of each slot 21 to match the groove of the part 01 to be inserted or removed, thereby limiting the part 01 to be inserted or removed in the axial direction of the slot 21 and preventing it from sliding back and forth along the axial direction of the slot 21. This design can fix the part 01 to be inserted or removed during the insertion and removal process, ensuring that the part 01 is aligned with the device to be used, thus improving the structural stability, reliability, and usability of the insertion and removal fixture.

[0042] It should be noted that, referring to Figure 4 The grille 2 can be provided with two rows of slots 21 arranged along the first direction. By designing the grille 2 into a double-row fishbone structure, the insertion and removal fixture can simultaneously insert and remove more parts 01 to be inserted and removed, further improving the insertion and removal efficiency of the parts 01 to be inserted and removed and reducing manpower. Using the insertion and removal fixture of this application, 4 / 8 / 16 parts 01 to be inserted and removed can be unlocked at the same time in a single operation. The specific number of unlocked parts is determined according to the modular design.

[0043] In some embodiments, the fixture body 1 includes a first plate 12 and a second plate 13 opposite to each other, and a grid 2 is connected between the first plate 12 and the second plate 13;

[0044] The driving part 31 and the unlocking part 32 of each driving lever 3 are respectively located on the side of the first plate 12 away from the second plate 13 and the side of the second plate 13 away from the first plate 12.

[0045] The first plate 12 is provided with a first lever assembly 4; and / or the second plate 13 is provided with a second lever assembly 5, both the first lever assembly 4 and the second lever assembly 5 including multiple drive levers 3.

[0046] One possible way to achieve this is, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the first plate 12, the second plate 13, and the grille 2 form a receiving cavity for accommodating multiple insertable / removable parts 01. A drive lever 3 is rotatably connected to either the first plate 12 or the second plate 13. The drive part 31 and the unlocking part 32 of each drive lever 3 are located on opposite sides of the fixture body 1 along its thickness direction. That is, each drive lever 3 passes through the first plate 12 and the second plate 13, with the drive part 31 located closer to the first plate 12 or the second plate 13, and correspondingly, the unlocking part 32 located closer to the second plate 13 or the first plate 12. It should be noted that since the latch 011 of the insertable / removable part 01 without the corresponding unlocking part 32 is always pressed or has no latch 011 structure, the insertable / removable part 01 in this part can be inserted / removed without unlocking. However, the insertable / removable part 01 corresponding to the unlocking part 32 requires pressing to unlock. Therefore, both the first lever assembly 4 and the second lever assembly 5 include multiple drive levers 3, which can increase the connection stability between the insertable / removable part 01 and the device to be used after insertion.

[0047] When the insertion / removal fixture is used to insert or remove a row of components 01, the drive lever 3 can be connected to the first plate 12 or the second plate 13. For example, the first plate 12 is connected to a first lever assembly 4, which includes multiple drive levers 3; or, the second plate 13 is connected to a second lever assembly 5, which includes multiple drive levers 3, to realize the insertion and removal of a single row of components 01.

[0048] When the insertion / removal fixture is used to insert or remove two rows of parts 01 to be inserted or removed, such as Figure 2 As shown, the drive lever 3 can be connected to the first plate 12 and the second plate 13. For example, the first plate 12 is connected to the first lever assembly 4, and the second plate 13 is connected to the second lever assembly 5. Both the first lever assembly 4 and the second lever assembly 5 include multiple drive levers 3 to enable the insertion and removal of the two rows of insertable / removable parts 01.

[0049] Understandably, since each drive lever 3 passes through the first plate 12 and the second plate 13, when the drive part 31 near the first plate 12 is pressed, the unlocking part 32 near the second plate 13 will press the latches 011 of the row of insertable / removable parts 01 near the second plate 13 in the second direction. Similarly, when the drive part 31 near the second plate 13 is pressed, the unlocking part 32 near the first plate 12 will press the latches 011 of the row of insertable / removable parts 01 near the first plate 12 in the second direction. Pressing the drive parts 31 on both sides simultaneously can unlock both rows of insertable / removable parts 01.

[0050] In some embodiments, the insertion and removal fixture further includes a rotating shaft, and the drive lever 3 connected to the first plate 12 and the drive lever 3 connected to the second plate 13 are rotatably connected via the rotating shaft.

[0051] One possible way to achieve this is, such as Figure 7 As shown, the drive lever 3 connected to the first plate 12 and the second plate 13 can also be rotated via a rotating shaft (not shown in the figure) to form a scissor-like structure. This configuration allows for pressing the drive sections 31 on both sides while unlocking the component to be inserted or removed 01, improving operational convenience and further enhancing insertion and removal efficiency.

[0052] In some embodiments, a plurality of drive levers 3 are respectively provided corresponding to a plurality of slots 21 located at the ends.

[0053] One possible way to achieve this is, such as Figure 1 As shown, four drive levers 3 connected to the first plate 12 and the second plate 13 are correspondingly arranged with the four slots 21 at the middle end of the grille 2, and are used to unlock the latches 011 of the insertable / removable parts 01 in the four slots 21 at the edge. Setting multiple drive levers 3 at the end makes it easier for the user to press the drive part 31. In this case, one unlocking part 32 corresponds to one slot 21, that is, one unlocking part 32 is used to unlock one insertable / removable part 01. The latches 011 of the insertable / removable parts 01 that do not correspond to the unlocking part 32 are engaged with the fixture body 1 and are always in a pressed state, or there is no latch 011 structure, that is, the insertable / removable parts 01 in this part are always in an unlocked state and can be inserted or removed along with the insertable / removable parts 01 corresponding to the unlocking part 32.

[0054] It should be noted that, during the design process, the size of the unlocking part 32 along the first direction can be increased according to the actual situation, so that one unlocking part 32 corresponds to multiple slots 21. In this case, one unlocking part 32 can be used to unlock multiple insertable / removable parts 01, and the specific number of insertable / removable parts 01 that can be unlocked is not limited. It can be understood that, in addition to corresponding to the multiple slots 21 located at the ends, the multiple driving levers 3 can also correspond to the multiple slots 21 located in the middle, or correspond to the multiple slots 21 in other parts, and the specific corresponding positions are not limited.

[0055] In some embodiments, the slot 21 includes a first slot 211, and the first slot 211 does not correspond to the unlocking part 32;

[0056] The first plate 12 has a plurality of first protrusions 121 on the side facing the grille 2, and each first protrusion 121 is correspondingly provided with a first slot 211; and / or, the second plate 13 has a plurality of second protrusions 131 on the side facing the grille 2, and each second protrusion 131 is correspondingly provided with a first slot 211.

[0057] One possible way to achieve this is, such as Figure 2 As shown, combined with Figure 1 , Figure 5 , Figure 6When the grille 2 includes two rows of slots 21, the first slot 211 in the two rows of slots 21 can be respectively configured to correspond to the first protrusion 121 of the first plate 12 and the second protrusion 131 of the second plate 13, for always pressing the buckle 011 of the component to be inserted or removed. Under the pulling action when pulling out, the first protrusion 121 and the second protrusion 131 will generate friction with the buckle 011. Under the action of friction, the first protrusion 121 and the second protrusion 131 will drive the component to be inserted or removed 01 to move out of the device to be used, so as to facilitate the insertion or removal of the component to be inserted or removed 01 that does not correspond to the unlocking part 32.

[0058] It is understood that when the grille 2 includes a single row of slots 21, the first slot 211 in the slot 21 can be correspondingly set with the first protrusion 121 of the first plate 12, or it can be correspondingly set with the second protrusion 131 of the second plate 13. It should be noted that only one of the first plate 12 and the second plate 13 needs to be provided with a protrusion corresponding to the first slot 211. In addition, the first protrusion 121 and the second protrusion 131 can also limit the latch 011 of the component to be inserted or removed 01 in the axial direction of the slot 21 to prevent the component to be inserted or removed 01 from coming out of the insertion or removal fixture.

[0059] In some embodiments, the unlocking part 32 is provided with a third protrusion 321 at one end near the slot 21.

[0060] One possible way to achieve this is, such as Figure 3 and Figure 7 As shown, the third protrusion 321 is used to press the latch 011 of the component to be inserted or removed 01, so as to facilitate the insertion or removal of the component to be inserted or removed corresponding to the unlocking part 32 under the action of friction. In addition, the third protrusion 321 can also limit the latch 011 of the component to be inserted or removed 01 in the axial direction of the slot 21 to prevent the component to be inserted or removed 01 from coming out of the insertion or removal fixture.

[0061] In some embodiments, the third protrusion 321 is provided with a wear-resistant layer (not shown in the figure).

[0062] In one possible implementation, the outer wall of the third protrusion 321 that contacts the component to be inserted or removed 01 is covered with a wear-resistant material (such as polyoxymethylene (POM) engineering plastic) to increase the friction between the third protrusion 321 and the component to be inserted or removed 01, thereby facilitating the insertion and removal of the component to be inserted or removed 01.

[0063] In some embodiments, in each drive lever 3, the length ratio of the drive part 31 to the unlocking part 32 is 1:3 to 1:5. For example, the length ratio of the drive part 31 to the unlocking part 32 can be 1:3, 1:3.5, 1:4, 1:4.5, 1:5, etc., and the specific ratio is not limited. The lever principle formula is: F输出 =F 输入 ×(L 驱动部 / L 解锁部 If the length ratio of the driving part 31 to the unlocking part 32 is designed to be 1:3-1:5, then F 输入 It can be amplified 3-5 times. For example, if the manual pressing force is 10N, with a 1:5 lever ratio design, the output force can reach 50N. By designing the lever ratio of the drive lever 3, the operating force can be amplified, the manual pressing intensity can be reduced, and the insertion and removal of the insert / remove part 01 can be made easier.

[0064] In some embodiments, the fixture body 1 and the grid 2 are integrally formed. By designing the fixture body 1 and the grid 2 as an integral structure, the structural stability and reliability of the insertion and removal fixture can be further increased.

[0065] It should be noted that the insertion / removal fixture of this application is not limited to unlocking LC-type optical fibers. This solution of using a drive lever to press the latch can be used in any scenario requiring unlocking. The insertion / removal fixture of this application also supports loopback and cable connection. Furthermore, users can improve its mechanical performance by changing the hinge position between the drive lever and the fixture body, as well as the shape of the drive lever and other structural features.

[0066] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
