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] The fixture body includes a plurality of slots arranged along a first direction for clamping the plurality of parts to be inserted or removed;

[0007] The drive board includes a fixed end and an unlocking end. The fixed end is fixed to the fixture body, and the unlocking end can move closer to or further away from the slot relative to the fixture body along a second direction. It is used to press the plurality of insertable and removeable parts when the unlocking end is close to the slot. The second direction is perpendicular to the first direction and perpendicular to the axial direction of the slot.

[0008] 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 and a drive plate. The fixture body includes multiple slots arranged along a first direction, each slot for clamping one component to be inserted or removed. The drive plate includes a fixed end and an unlocking end. The fixed end is fixed to the fixture body to fix the drive plate to the fixture body. The unlocking end is a free end, which can move closer to or further away from the slots relative to the fixture body along a second direction. When the unlocking end moves closer to the slot, it can press down on multiple components to be inserted or removed in the slot, thereby unlocking the components and allowing them to be removed. After unlocking, the unlocking end returns to its natural state and moves away from the slot, releasing the pressure on the components to be inserted or removed. In the application of the insertion / removal fixture, multiple slots on the fixture body clamp multiple components to be inserted or removed, such as the plug portion of an LC-type optical fiber. The drive board, through a fixed end cap, is fixed to the fixture body to fix the position of the components to be inserted or removed. The drive board maintains contact with the latches of the components to be inserted or removed, allowing multiple components to be inserted or removed together into the device to be used, such as a switch. When it is necessary to remove multiple components, the drive board can be pressed manually or with the aid of other tools in a second direction, causing the unlocking end of the drive board to approach the components to be inserted or removed and press the latches of the components, thereby unlocking the latches of multiple components to be inserted or removed. Then, the insertion / removal fixture is pulled outward. Under the action of pulling force, friction is generated between the unlocking end and the latches. Under the action of friction, the unlocking end will move the components to be inserted or removed out of the device to be used, thus completing the removal of multiple components. The insertion and removal fixture of this application can simultaneously insert and remove multiple components, which can significantly improve the insertion and removal efficiency of the components. It also has a small number of components and a simple and reliable structure.

[0009] In some embodiments, the drive plate further includes a deformable portion located between the fixed end and the unlocking end, wherein the stiffness of the fixed end and the unlocking end is greater than the stiffness of the deformable portion.

[0010] In some embodiments, the deformable portion includes an auxiliary deformation groove or an auxiliary deformation hole.

[0011] In some embodiments, the deformable part is a shape memory alloy plate.

[0012] In some embodiments, the drive plate further includes a handle portion located between the deformable portion and the unlocking end.

[0013] In some embodiments, the unlocking end is provided with a plurality of protrusions on the side facing the slot, and one protrusion is provided corresponding to one slot.

[0014] In some embodiments, the fixture body includes a frame and a grid, wherein the frame and the grid cooperate to form the slot.

[0015] In some embodiments, the frame and the grille are integrally formed.

[0016] In some embodiments, the frame and the grille cooperate to form a first slot group and a second slot group arranged side by side, and both the first slot group and the second slot group include a plurality of slots arranged along a first direction;

[0017] The drive plate includes a first drive plate and a second drive plate, which are respectively disposed on both sides of the fixture body along the second direction. The first drive plate includes a first fixed end and a first unlocking end, and the second drive plate includes a second fixed end and a second unlocking end. The first fixed end and the second fixed end are both fixed to the fixture body. The first unlocking end is used to press the corresponding insertion / removal part of the first slot group when it is close to the first slot group, and the second unlocking end is used to press the corresponding insertion / removal part of the second slot group when it is close to the second slot group.

[0018] In some embodiments, the inner wall of the slot is provided with a limiting portion for limiting the insertion / removal of the component along the axial direction of the slot. Attached Figure Description

For example, A and / or B can represent: A alone, A and B simultaneously, and B alone.

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.

[0030] like Figures 1-8 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:

[0031] The fixture body 1 includes a plurality of slots 11 arranged along a first direction for clamping a plurality of insertable / removable parts 01;

[0032] The drive plate 2 includes a fixed end 21 and an unlocking end 22. The fixed end 21 is fixed to the fixture body 1 and is used to fix the drive plate 2 to the fixture body 1. The unlocking end 22 can move closer to or further away from the slot 11 relative to the fixture body 1 in a second direction and is used to press multiple insertable / removable parts 01 when the unlocking end 22 is close to the slot 11. The second direction is perpendicular to the first direction and perpendicular to the axial direction of the slot 11.

[0033] 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 and a drive plate 2. The fixture body 1 includes multiple slots 11 arranged along a first direction, and each slot 11 is used to clamp one component 01 to be inserted or removed. The drive plate 2 includes a fixed end 21 and an unlocking end 22. The fixed end 21 is fixed to the fixture body 1 to fix the drive plate 2 to the fixture body 1. The unlocking end 22 is a free end, which can move closer to or further away from the slots 11 relative to the fixture body 1 along a second direction. When the unlocking end 22 moves closer to the slots 11, it can press multiple components 01 to be inserted or removed in the slots 11 to unlock the components 01 to be inserted or removed, and then pull out the components 01 to be inserted or removed. After unlocking, the unlocking end 22 returns to its natural state and moves away from the slots 11 to release the pressure on the components 01 to be inserted or removed.

[0034] like Figures 1-4 As shown, during the application of the insertion / removal fixture, multiple slots 11 of the fixture body 1 clamp multiple components 01 to be inserted / removed, such as the plug portion of an LC-type optical fiber. The drive board 2 is fixedly covered by the fixed end 21 of the fixture body 1 to fix the position of the components 01 to be inserted / removed. The drive board 2 maintains contact with the latches of the components 01 to be inserted / removed, so that multiple components 01 to be inserted / removed can be inserted into the device to be used, such as a switch. When it is necessary to remove multiple components 01 to be inserted / removed, the drive board 2 can be pressed manually or with the help of other tools along the second direction, so that the unlocking end 22 of the drive board 2 moves close to the component 01 to press the latch 011 of the component 01 to be inserted / removed, thereby unlocking the latches 011 of multiple components 01 to be inserted / removed. Next, the insertion and removal fixture is pulled outward. Under the action of the pulling force, friction will be generated between the unlocking end 22 and the buckle 011. Under the action of the friction, the unlocking end 22 will drive the insertion and removal parts 01 to be moved out of the device to be used, and finally the removal of multiple insertion and removal parts 01 is completed.

[0035] 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.

[0036] In some embodiments, the drive plate 2 further includes a deformable portion 23, which is located between the fixed end 21 and the unlocking end 22. The stiffness of both the fixed end 21 and the unlocking end 22 is greater than the stiffness of the deformable portion 23.

[0037] One possible way to achieve this is, such as Figure 1 and Figure 3As shown, when multiple insertable / removable components 01 need to be removed, the deformable portion 23 can be pressed along the second direction to cause elastic deformation. Since the deformable portion 23 is connected to the unlocking end 22, after the deformable portion 23 deforms, the entire drive plate 2 will rotate at a small angle around the fixed end 21 as the axis. This will cause the unlocking end 22 to move closer to the insertable / removable component 01 to press the latch 011 of the insertable / removable component 01, thereby unlocking the latch 011 of multiple insertable / removable components 01. The stiffness of the deformable portion 23 of the drive plate 2 is less than the stiffness of other areas of the drive plate 2. The lower stiffness of the deformable portion 23 is beneficial to increasing the deformability of the deformable portion 23, which is beneficial to achieving deformation of the deformable portion 23 under a smaller force, thereby causing the unlocking end 22 to move closer to the insertable / removable component 01. The greater stiffness of other areas, such as the greater stiffness of the unlocking end 22, is beneficial to pressing the insertable / removable component 01 and improving the structural reliability. It should be noted that the deformable part 23 can be made of engineering plastics such as acrylonitrile butadiene styrene copolymer (ABS), and the specific material is not limited.

[0038] In some embodiments, the deformable portion 23 includes an auxiliary deformation groove or an auxiliary deformation hole 231.

[0039] One possible way to achieve this is, such as Figure 1 and Figure 3 As shown, the deformable part 23 is provided with an auxiliary deformation hole 231, which is elliptical in shape and extends along the first direction. By providing the auxiliary deformation hole 231, the deformable part 23 can be more easily deformed when pressed, reducing the force required to manually press the deformable part 23. This, in turn, makes it easier to move the unlocking end 22 closer to the insert / remove part 01, optimizing the mechanical properties of the deformable part 23 and making its deformation more controllable. It should be noted that the position of the auxiliary deformation hole 231 can also be replaced by an auxiliary deformation groove, which can also be an elliptical shape extending along the first direction; the specific shape is not limited.

[0040] In some embodiments, the deformable part 23 is a shape memory alloy plate. The unlocking end 22 is driven by a shape memory alloy, and the deformation of the shape memory alloy plate is controlled by current to achieve electric control, which is beneficial for automating the insertion and removal of the fixture. It should be noted that the entire drive board 2 can also be designed as a shape memory alloy plate, which can also achieve the insertion and removal process of the component 01 to be inserted or removed.

[0041] In some embodiments, the drive plate 2 further includes a handle portion 24, which is located between the deformable portion 23 and the unlocking end 22.

[0042] One possible way to achieve this is, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the handle portion 24 of the drive plate 2 is recessed, and the connection between the handle portion 24 and the unlocking end 22 is curved. This curve includes a protrusion towards the unlocking end 22 to accommodate a finger. This design makes it easier to determine the position where force is applied, making it easier to press the drive plate 2, reducing the pressing force, and thus facilitating the unlocking of the insert / remove component 01.

[0043] It should be noted that the fixed end 21, unlocking end 22, variable part 23 and handle part 24 of the drive board 2 in this application embodiment can be made into an integral structure to realize mechanical linkage and facilitate the unlocking of the insert / remove part 01.

[0044] In some embodiments, the unlocking end 22 is provided with a plurality of protrusions 221 on the side facing the slot 11, and one protrusion 221 is provided corresponding to one slot 11.

[0045] One possible way to achieve this is, such as Figure 2 As shown, the unlocking end 22 is provided with multiple protrusions 221, each corresponding to a slot 11. When the unlocking end 22 moves close to the slot 11, the protrusions 221 press against the latches 011 of the component to be inserted or removed, and the friction between the protrusions 221 and the latches 011 causes the component to be inserted or removed to be pulled out of the device. In addition, the protrusions 221 can also limit the latches 011 of the component to be inserted or removed in the axial direction of the slot 21 to prevent the component to be inserted or removed from the insertion / removal fixture.

[0046] It should be noted that multiple protrusions 221 can also be connected to each other to form an integrated structure, which can also achieve the unlocking of the latch 011 of the plug-in / plug-out component 01 by pressing.

[0047] In some embodiments, the fixture body 1 includes a frame 12 and a grid 13, with the frame 12 and the grid 13 cooperating to form a slot 11.

[0048] One possible way to achieve this is, such as Figure 2 As shown, the frame 12 and grid 13 of the fixture body 1, along with the two drive plates 2, together form a cavity for accommodating the component 01 to be inserted or removed. Figure 7 As shown, the grille 13 includes a plurality of grids 131 arranged along a first direction. Figure 8 As shown, the frame 12 and the grille 13 cooperate to form a slot 11. Each slot 11 can accommodate the plug portion of the component to be plugged in or removed 01, and can limit the multiple components to be plugged in or removed 01 in the first direction.

[0049] In some embodiments, the frame 12 and the grille 13 are integrally formed. By designing the frame 12 and the grille 2 as an integral structure, the structural stability and reliability of the insertion and removal fixture can be further increased.

[0050] In some embodiments, the frame 12 and the grille 13 cooperate to form a first slot group 3 and a second slot group 4 arranged side by side, and both the first slot group 3 and the second slot group 4 include a plurality of slots 11 arranged along a first direction.

[0051] The drive plate 2 includes a first drive plate 5 and a second drive plate 6. The first drive plate 5 and the second drive plate 6 are respectively disposed on both sides of the fixture body 1 along the second direction. The first drive plate 5 includes a first fixed end 51 and a first unlocking end 52. The second drive plate 6 includes a second fixed end 61 and a second unlocking end 62. The first fixed end 61 and the second fixed end 62 are both fixed to the fixture body 1. The first unlocking end 52 is used to press the insert / remove part 01 corresponding to the first slot group 3 when it is close to the first slot group 3. The second unlocking end 62 is used to press the insert / remove part 01 corresponding to the second slot group 4 when it is close to the second slot group 4.

[0052] One possible way to achieve this is, such as Figure 2 , Figure 7 and Figure 8 As shown, the grille 13 can be configured with two rows of grids 131 arranged along the first direction. By designing the grille 13 into a double-row herringbone structure, the insertion and removal fixture can simultaneously insert and remove more parts 01 to be inserted or removed, further improving the insertion and removal efficiency of the parts 01 to be inserted or removed and reducing manpower. Using the insertion and removal fixture of this application, 4 / 8 / 16 parts 01 to be inserted or removed can be unlocked simultaneously in a single operation, and the specific number of unlocked parts is determined according to the modular design.

[0053] It is understandable that when the insertion / removal fixture is used to insert or remove a row of components 01, the grid 13 can be designed with a structure having a single row of grids 131 arranged along the first direction. In this case, only a drive plate 2 needs to be provided on one side of the fixture body 1 to realize the insertion and removal of a single row of components 01.

[0054] In some embodiments, the inner wall of the slot 11 is provided with a limiting portion 111 for limiting the insertion / removal member 01 along the axial direction of the slot 11.

[0055] One possible way to achieve this is, such as Figure 7 and Figure 8As shown, a limiting part 111 is provided on the inner wall of each slot 11 to match the groove of the part to be inserted or removed 01, thereby limiting the part to be inserted or removed 01 in the axial direction of the slot 11 and preventing the part to be inserted or removed 01 from sliding back and forth along the axial direction of the slot 11. This setting can fix the part to be inserted or removed 01 during the insertion or removal process, so that the part to be inserted or removed 01 is aligned with the equipment to be used, improving the structural stability, reliability and usability of the insertion and removal fixture.

[0056] It should be noted that the insertion / removal fixture of this application is not limited to unlocking LC-type optical fibers. This solution, which uses a drive board to press the latch for unlocking, can be used in any scenario requiring latch pressing. The insertion / removal fixture also supports loopback and cable connection. Furthermore, users can optimize its mechanical performance by changing the hinge position between the drive board and the fixture body, as well as the shape of the drive board. Using the insertion / removal fixture provided in this application, efficiency can be increased by approximately 40 times compared to traditional methods (reducing the operation time for 128 components from 10 minutes to 15 seconds), and damage to the latching parts caused by uneven operating force can be avoided.

[0057] 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.
