Description

Technical Field

[0001] This utility model relates to the field of chip-optical fiber coupling, specifically to an auxiliary optical fiber-chip coupling device and a detection coupler. Background Technology

[0002] With the rapid development of communication technology, signal transmission speed has become a critical technology requiring breakthroughs. Factors affecting signal transmission speed include coupling conditions, fiber type, transmission distance, and the technology used. The coupling between the chip and the fiber is one of the important parameters affecting signal transmission speed. At normal coupling points, the chip or fiber can be fixed by an adsorption structure, thereby coupling the chip and fiber through curing adhesive or solder. If the fiber size is small, and the coupling point between the chip and the fiber is inside a deep cavity, the suction force of the adsorption structure may be insufficient, leading to coupling point misalignment during the curing process. If a bird clip is used for clamping, and the deep cavity is narrow (e.g., within 5mm), insufficient clamping strength may be encountered, similarly causing the final coupling point between the fiber and the chip to shift during the curing process.

[0003] Therefore, how to provide a coupling device that prevents the chip from shifting at the coupling point with the optical fiber is a technical problem that urgently needs to be solved. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the present invention provides an auxiliary optical fiber coupling device and a detection coupler to solve at least one of the above-mentioned technical problems.

[0005] To achieve the above and other related objectives, the technical solution provided in this application is as follows.

[0006] In a first aspect, this application provides an auxiliary coupling device for an optical fiber and a chip. The coupling device includes an adsorption component, a coil, a gripping component for supporting the adsorption component, a connector for connecting the adsorption component and the gripping component, and an adapter plate for fixing the gripping component. The first end of the adsorption component is used to adsorb the optical fiber. The coil is wound around the periphery of the adsorption component in the same direction. The coil and the adsorption component constitute an electromagnet. The second end of the adsorption component is connected to the first end of the connector. The second end of the connector is connected to the first end of the gripping component. The adapter plate is provided with a snap-fit ​​hole, and the adapter plate fixes the gripping component through the snap-fit ​​hole.

[0007] In one embodiment of the present invention, the coupling device further includes a gasket disposed at the first end of the adsorption component.

[0008] In one embodiment of the present invention, the coupling device further includes a coil limiting component, which is disposed at the first end of the adsorption component.

[0009] In one embodiment of the present invention, the gripping component includes a rod-shaped structure that passes through the snap-fit ​​hole.

[0010] In one embodiment of the present invention, the gripping component is provided with a limiting protrusion in the circumferential direction. The limiting protrusion surrounds the axial direction of the gripping component. The first end of the limiting protrusion is used to limit the snap-fit ​​hole. The first end of the limiting protrusion is the end of the limiting protrusion away from the adsorption component.

[0011] In one embodiment of the present invention, a first connecting groove is formed on the outer wall of the first end of the connector around the axial direction of the adsorption component, and a second connecting groove is formed on the outer wall of the second end of the connector around the axial direction of the gripping component.

[0012] In one embodiment of the present invention, the shape of the outer wall of the first end of the connector is not the same as the shape of the outer wall of the second end of the connector.

[0013] In one embodiment of this utility model, the dimensions of the first connecting groove and the second connecting groove are the same.

[0014] In a second aspect, this application also provides a probe coupler that includes a coupling device between an auxiliary optical fiber and a chip as described above.

[0015] This application provides an auxiliary optical fiber coupling device and a detection coupler for a chip. The coupling device includes an adsorption component, a coil, a holding component for supporting the adsorption component, a connector for connecting the adsorption component and the holding component, and an adapter plate for fixing the holding component. The first end of the adsorption component is used to adsorb the optical fiber. The coil is wound around the periphery of the adsorption component in the same direction, forming an electromagnet with the coil. The second end of the adsorption component is connected to the first end of the connector, and the second end of the connector is connected to the first end of the holding component. The adapter plate has snap-fit ​​holes, through which the holding component is fixed. The auxiliary optical fiber coupling technology provided in this application places the coil around the periphery of the adsorption component, thus forming an electromagnet. When the coil is energized, the electromagnet causes the inner wall of the adsorption component to act as a magnet, exerting an attractive force on the optical fiber at the first end of the adsorption component. This enhances the attractive force of the adsorption component on the device to be coupled, ensuring that the coupling point does not shift when the optical fiber and the chip are coupled in a deep cavity.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0025] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention can be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0026] With the rapid development of communication technology, signal transmission speed has become a critical technology requiring breakthroughs. Factors affecting signal transmission speed include coupling conditions, fiber type, transmission distance, and the technology used. The coupling between the chip and the fiber is one of the important parameters affecting signal transmission speed. At normal coupling points, the chip or fiber can be fixed by an adsorption structure, thereby coupling the chip and fiber through curing adhesive or solder. If the fiber size is small, and the coupling point between the chip and the fiber is inside a deep cavity, the suction force of the adsorption structure may be insufficient, leading to coupling point misalignment during the curing process. If a bird clip is used for clamping, and the deep cavity is narrow (e.g., within 5mm), insufficient clamping strength may be encountered, similarly causing the final coupling point between the fiber and the chip to shift during the curing process of the adhesive or solder.

[0027] To solve the above problems, such as Figure 1 As shown, this application provides an auxiliary coupling device for optical fiber and chip. The coupling device includes an adsorption component 110, a coil 120, a holding component 140 for supporting the adsorption component 110, a connector 130 for connecting the adsorption component 110 and the holding component 140, and an adapter plate 150 for fixing the holding component 140. The first end of the adsorption component 110 is used to adsorb optical fiber. The coil 120 is wound around the periphery of the adsorption component 110 in the same direction. The coil 120 and the adsorption component 110 constitute an electromagnet. The second end of the adsorption component 110 is connected to the first end of the connector 130, and the second end of the connector 130 is connected to the first end of the holding component 140. The adapter plate 150 is provided with a snap-fit ​​hole 160, and the adapter plate 150 fixes the holding component 140 through the snap-fit ​​hole 160.

[0028] Specifically, such as Figure 1 As shown, the upper end of the gripping component is snapped into the adapter plate 150 through the snap-fit ​​hole 160, thereby fixing the adsorption component 110 through the gripping component 140. The coil 120 is wound around the straw in the same direction, thereby forming an electromagnet.

[0029] It should be noted that the adsorption component 110 is made of a magnetically conductive material, such as silicon steel. The adsorption component 110 and the coil 120 form an electromagnet. The coils are connected in series. When the coils are energized, the tube wall of the adsorption component 110 acts as a magnet and exerts an upward pulling force on the optical fiber at the first end of the adsorption component 110.

[0030] In detail, such as Figure 2 As shown, the coupling device also includes a gasket 170, which is disposed at the first end of the adsorption component 110.

[0031] In detail, the coupling device also includes a coil limiting component (not shown in the figure), which is disposed at the first end of the adsorption component 110.

[0032] It should be emphasized that the material of the gasket 170 includes polyester polyurethane. After the coil 160 is energized, the adsorption component 110 heats up, causing the temperature of the gasket 170 to rise. When the temperature of the gasket 170 meets the preset temperature condition, which is 45~55℃, the gasket 170 undergoes thermoplastic softening. After softening, it is used as a sealing strip to improve the sealing effect of the end face and contact surface of the adsorption component 110 and increase the gas suction force inside the tube of the adsorption component 110.

[0033] In detail, such as Figure 2 As shown, the gripping component 140 includes a rod-shaped structure that passes through the snap-fit ​​hole 160.

[0034] In detail, such as Figure 2 As shown, the gripping component 140 is provided with a limiting protrusion 180 in the circumferential direction. The limiting protrusion 180 surrounds the axial direction of the gripping component 140. The first end of the limiting protrusion 180 is used to limit the snap hole 160. The first end of the limiting protrusion 180 is the end of the limiting protrusion 180 away from the adsorption component 110.

[0035] In detail, such as Figure 2 As shown, the first end of the connector 130 has a first connecting groove formed around the axial direction of the adsorption component 110 on its outer wall, and the second end of the connector 130 has a second connecting groove formed around the axial direction of the gripping component on its outer wall.

[0036] To facilitate quick installation of the adsorption component 110, the shape of the outer wall of the first end of the connector 110 is not the same as the shape of the outer wall of the second end of the connector 130. For example, the outer wall of the first end of the connector 110 is a polygonal shape, and the outer wall of the second end of the connector 110 is a circle.

[0037] To facilitate quick installation of the adsorption component 110, the dimensions of the first connecting groove and the second connecting groove can be set to be the same. When the size and internal thread structure of the first connecting groove are the same as those of the second connecting groove, the holding component 140 can be connected to either the first or the second connecting groove, and the straw component 110 can be connected to either the first or the second connecting groove. That is, when installing the straw component 110, one end of the connector 130 can be connected to the adsorption component 110, and the other end of the connector 130 can be directly connected to the holding component 140, simplifying the identification process for workers installing the adsorption component 110.

[0038] Please see Figures 1-4 The working principle of the auxiliary optical fiber and chip coupling device provided in this application is as follows:

[0039] The adapter plate 150 fixes the holding component 140. During operation, the inner tube of the adsorption component 110 generates attraction and energizes the coil 120. The coil 120 and the adsorption component 110 form an electromagnet, causing the adsorption component 110 to heat up, resulting in the gasket 170 reaching a temperature of 45~55℃. The gasket 170 then undergoes thermoplastic softening. Figure 3 As shown, the adsorption component 110 improves the sealing between itself and the optical fiber 190 through the gasket 170, thereby increasing the gas suction force inside the adsorption component 110 tube.

[0040] like Figure 4 As shown, the chip is placed under the housing 200. The optical fiber 190 is attracted by the coupling device to put the optical fiber 190 into the deep cavity. When the optical fiber 190 is coupled with the chip, the sum of the attraction and pull generated by the adsorption component 110 is greater than the pull generated by the curing adhesive or solder. Therefore, after the coupling is completed, the coupling point between the optical fiber and the chip does not shift.

[0041] It should be noted that the principle of setting the chip at the first end of the adsorption component 110 is the same as the principle of setting the optical fiber at the first end of the adsorption component 110, and will not be repeated here.

[0042] This application also provides a probe coupler, including multiple auxiliary optical fibers and chip coupling devices as described above, to improve the temperature resistance of the probe coupler.

[0043] This application provides an auxiliary optical fiber and chip coupling device and a detection coupler. The coupling device includes an adsorption component, a coil, a holding component for supporting the adsorption component, a connector for connecting the adsorption component and the holding component, and an adapter plate for fixing the holding component. The first end of the adsorption component is used to adsorb the optical fiber. The coil is wound around the periphery of the adsorption component in the same direction. The adsorption component and the coil form an electromagnet. The second end of the adsorption component is connected to the first end of the connector. The second end of the connector is connected to the first end of the holding component. The adapter plate is provided with a snap-fit ​​hole, and the adapter plate fixes the holding component through the snap-fit ​​hole. The auxiliary optical fiber and chip coupling technology provided in this application involves placing a coil around the periphery of the adsorption component to form an electromagnet. When the coil is energized, the electromagnet causes the inner wall of the adsorption component to act as a magnet, creating an attractive force on the optical fiber at the first end of the adsorption component, thereby enhancing the attraction force of the adsorption component to the device to be coupled. Simultaneously, the gasket is heated, resulting in thermoplastic softening, which improves the sealing between the adsorption component and the device to be coupled, ensuring that the coupling point does not shift when the optical fiber and chip are coupled in a deep cavity. This technology supplements the attraction force under size constraints to prevent the device to be coupled from shifting, and because the modification is minor, it has good compatibility with the original system.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
