Abstract
Description
Technical Field
[0001] This application relates to the field of testing equipment technology, and in particular to a dustproof component for an interface and an optical module testing device. Background Technology
[0002] Dustproof structures are usually required at interfaces to prevent abnormal contact caused by dust. Existing technologies typically use rubber plugs or latches to prevent dust from entering the interface. Specifically, dustproofing and shielding are achieved by direct interference or fastening between the dustproof sheet (or rubber plug) and the hole to be shielded. However, this interference or fastening method results in poor concealment of the dustproof component and a large space occupation. Furthermore, since the dustproof component is mostly a split design, it is easy for parts to be lost. Utility Model Content
[0003] In view of the above-mentioned problems of the prior art, the purpose of this application is to place the dustproof sheet on the panel to reduce the space occupied by the dustproof component and avoid the loss of dustproof parts.
[0004] To address the aforementioned problems, this application provides a dustproof component for an interface, disposed on a panel corresponding to the interface, comprising a dustproof sheet and an elastic element.
[0005] The panel is provided with a clearance opening, which corresponds to the interface.
[0006] The dustproof sheet is disposed on the panel and is correspondingly disposed to the clearance opening. The dustproof sheet is provided with a first connection point connected to the panel and a second connection point connected to one end of the elastic member; the other end of the elastic member is connected to a third connection point on the panel.
[0007] The dustproof sheet can rotate around the first connection point to switch between a covered state that covers the avoidance opening and a misaligned state that is not aligned with the avoidance opening.
[0008] In this embodiment of the application, the compression of the elastic element is maximized when the distance between the second connection point and the third connection point is the shortest.
[0009] In this embodiment of the application, when the dustproof sheet is in a covered state, the second connection point is located in the first position;
[0010] When the compression of the elastic element is at its maximum, the second connection point is located in the second position;
[0011] When the dustproof sheet is misaligned, the second connection point is located at the third position; the first position, the second position, and the third position are points on a moving circumference; the moving circumference refers to a circle with the first connection point as its center and the distance between the first connection point and the second connection point as its radius; the second position is located between the first position and the third position.
[0012] In this embodiment of the application, the dustproof sheet is further provided with a first protrusion for applying force.
[0013] In this embodiment of the application, the dustproof assembly further includes a switch piece, which includes an upper beam and a lower beam. When the dustproof sheet is in the covered state, the upper beam abuts against the first protrusion.
[0014] When the dustproof sheet is in the misaligned state, the lower beam abuts against the first protrusion.
[0015] In this embodiment of the application, the panel is provided with a first limiting groove, and the switch piece is provided with a second protrusion. The second protrusion can slide within the first limiting groove so that the dustproof sheet can switch between the covered state and the misaligned state.
[0016] In this embodiment of the application, the panel is further provided with a recessed portion, and the first limiting groove is disposed in the recessed portion. The shape of the recessed portion matches the switch piece to provide the movement space of the switch piece.
[0017] In this embodiment of the application, the panel is provided with a second limiting groove, and the first protrusion can slide within the second limiting groove so that the dustproof sheet can switch between the covered state and the misaligned state.
[0018] In this embodiment of the application, the panel includes a first outer shell and a second outer shell that are opposite to and connected to each other. The first outer shell is provided with a first opening, and the second outer shell is provided with a second opening. The first opening and the second opening are correspondingly arranged to form the avoidance opening.
[0019] Both the dustproof sheet and the elastic element are disposed within the receiving space formed by the first outer shell and the second outer shell.
[0020] On the other hand, this application also provides an optical module testing device, the testing device including a test chamber, a fixture and at least one dustproof component as described in the embodiments of this application;
[0021] The fixture is disposed inside the test chamber, and the fixture includes an interface for connecting to the optical module under test, and the clearance opening is provided corresponding to the interface.
[0022] Due to the above technical solution, the dustproof component described in this application has the following beneficial effects:
[0023] By placing a dustproof sheet on the panel, and allowing the dustproof sheet to rotate at the first connection point to change its state—specifically, switching between a covered state that covers the clearance opening and a misaligned state that is not aligned with the clearance opening—the interface can be shielded or exposed. Simultaneously, an elastic element connected to the second connection point of the dustproof sheet provides a restoring force to its movement. This dustproof assembly not only protects the test structure from dust but also reduces the space occupied by the dustproof assembly and prevents the loss of dustproof components.

[0035] Combination Figure 1-2 This application describes a dustproof component for an interface, which is disposed on a panel corresponding to the interface. The dustproof component includes a panel 1, a dustproof sheet 2, and an elastic member 3. The panel 1 has an avoidance opening 11, which corresponds to the interface. The dustproof sheet 2 is disposed on the panel 1 and corresponds to the avoidance opening 11. The dustproof sheet 2 has a first connection point 21 connected to the panel 1 and a second connection point 22 connected to one end of the elastic member 3. The other end of the elastic member 3 is connected to a third connection point 17 on the panel 1. The dustproof sheet 2 can rotate around the first connection point 21, so that the dustproof sheet 2 can switch between a covered state covering the avoidance opening 11 and a misaligned state that is not aligned with the avoidance opening 11.
[0036] In a specific embodiment of this application, the interface refers to the interface corresponding to the connection port of the device under test.
[0037] In a specific embodiment of this application, when the dustproof sheet 2 is misaligned, the connection port of the device under test passes through the clearance opening 11 and connects to the interface; when the dustproof sheet 2 is covered, the interface is in a relatively closed state to prevent damage to the interface from the external environment, and the connection port cannot connect to the interface.
[0038] In a specific embodiment of this application, when the dustproof sheet 2 rotates around the first connection point 21, the second connection point 22 moves in an arc around the first connection point 21, thereby stretching or compressing the elastic element 3 and providing a restoring elastic force to the movement of the dustproof sheet 2.
[0039] In this embodiment, by placing the dustproof sheet 2 on the panel 1, and allowing the dustproof sheet 2 to rotate at the first connection point 21 to change its state, specifically, the dustproof sheet 2 switches between a covered state that covers the avoidance opening 11 and a misaligned state that is not aligned with the avoidance opening 11, thereby achieving both shielding and exposure of the interface; at the same time, the elastic member 3 is connected to the second connection point 22 of the dustproof sheet 2, which can provide a restoring elastic force for the movement of the dustproof sheet 2; the above-mentioned dustproof assembly not only achieves dust protection for the test structure, but also reduces the space occupied by the dustproof assembly and avoids the loss of dustproof parts.
[0040] refer to Figure 2 In this embodiment of the application, the compression of the elastic element 3 is maximized when the distance between the second connection point 22 and the third connection point 17 is the shortest.
[0041] In a specific embodiment of this application, the maximum compression of the elastic element 3 indicates that the elastic force of the elastic element 3 is the maximum.
[0042] In a specific embodiment of this application, when the elastic element 3 is located before or after the maximum compression, it will provide elastic force to the dustproof sheet 2 through the second connection point 22, thereby providing assistance for the movement of the dustproof sheet 2 and improving the convenience of changing the state of the dustproof sheet 2.
[0043] refer to Figure 2-4 In this embodiment, when the dustproof sheet 2 is in a covered state, the second connection point 22 is located in the first position; when the compression of the elastic member 3 is at its maximum, the second connection point 22 is located in the second position; when the dustproof sheet 2 is in a misaligned state, the second connection point 22 is located in the third position; the first position, the second position, and the third position are points on the motion circumference; the motion circumference refers to a circle with the first connection point 21 as the center and the distance between the first connection point 21 and the second connection point 22 as the radius; the second position is located between the first position and the third position.
[0044] In a specific embodiment of this application, when the second connection point 22 is located between the first position and the second position, the elastic member 3 provides elastic force to the dustproof sheet 2 through the second connection point 22, and the second connection point 22 moves to the first position, and the dustproof sheet 2 switches to the covered state; when the second connection point 22 is located between the second position and the third position, the elastic member 3 provides elastic force to the dustproof sheet 2 through the second connection point 22, and the second connection point 22 moves to the third position, and the dustproof sheet 2 switches to the misaligned state.
[0045] In this embodiment, by setting the positions of the second connection points 22 corresponding to the two states of the dustproof sheet 2 on both sides of the position of the second connection point 22 corresponding to the state of maximum compression of the elastic member 3, that is, the first position and the third position are located on both sides of the second position, the elastic member 3 can provide auxiliary force for state switching and lock the movement direction of the dustproof sheet 2 after the second connection point 22 passes through the second position, thereby improving the stability of the state switching of the dustproof sheet 2.
[0046] In this embodiment of the application, the dustproof sheet 2 is further provided with a first protrusion 23 for applying force.
[0047] In a specific embodiment of this application, the first protrusion 23 is disposed on the front side of the dustproof sheet 2, the front side of the dustproof sheet 2 refers to the side relatively far away from the interface; the first connection point 21 and the second connection point 22 are disposed on the back side of the dustproof sheet 2, the back side of the dustproof sheet 2 refers to the side close to the interface; the third connection point 17 is disposed on the side of the panel 1 close to the interface.
[0048] In this embodiment of the application, by providing a first protrusion 23 on the dustproof sheet 2, it is easier to apply a driving force to the dustproof sheet 2, thereby reducing the complexity of the force applied to the dustproof sheet 2 and improving the convenience of switching the state of the dustproof sheet 2.
[0049] In this embodiment of the application, the dustproof assembly further includes a switch piece 4, which includes an upper beam 41 and a lower beam 42. When the dustproof sheet 2 is in a covered state, the upper beam 41 abuts against the first protrusion 23; when the dustproof sheet 2 is in a misaligned state, the lower beam 42 abuts against the first protrusion 23.
[0050] In this embodiment, by setting a switch piece 4 and a first protrusion 23, and by having the upper beam 41 abut against the first protrusion 23 and the lower beam 42 abut against the first protrusion 23, a driving force can be indirectly applied to the first protrusion 23, further improving the convenience of applying a driving force to the dustproof sheet 2, thereby changing the balance state of the elastic element 3, and then realizing the state switching of the dustproof sheet 2 through the tension or thrust of the elastic element 3, improving the convenience of the state switching of the dustproof sheet 2; at the same time, the driving motion of the dustproof sheet 2 can be transformed into linear motion, improving the aesthetics of the driving motion.
[0051] refer to Figure 5 In this embodiment of the application, the panel 1 is provided with a first limiting groove 12, and the switch piece 4 is provided with a second protrusion 43. The second protrusion 43 can slide in the first limiting groove 12 so that the dustproof sheet 2 can switch between the covered state and the misaligned state.
[0052] In this embodiment of the application, by setting the first limiting groove 12, external support force is further provided for the balance state of the elastic member 3, ensuring the balance stability of the elastic member 3, thereby ensuring the state stability of the dustproof sheet 2 and improving the reliability of the dustproof assembly.
[0053] In a specific embodiment of this application, the position of the first protrusion 23 can be controlled by sliding the second protrusion 43.
[0054] In a specific embodiment of this application, the first limiting groove 12 is a straight groove, and the positions of the two ends of the first limiting groove 12 correspond to the first position and the second position, respectively.
[0055] In this embodiment of the application, the panel is also provided with a recessed portion 16, and a first limiting groove 12 is disposed in the recessed portion 16. The shape of the recessed portion 16 matches the switch piece 4 to provide the movement space of the switch piece 4.
[0056] In a specific embodiment of this application, as the second protrusion 43 slides within the first limiting groove 12, the switch piece 4 slides within the recess 16.
[0057] In this embodiment, by providing a recessed portion 16 on the panel, the switch piece 4 and the dustproof piece 2 can move and interfere only through the first protrusion 23, thereby reducing the friction between the surfaces, reducing the force when the dustproof piece 2 switches states, and thus improving the ease of switching the dustproof piece 2 states.
[0058] In another embodiment of this application, the panel is provided with a second limiting groove, and the first protrusion can slide within the second limiting groove to allow the dustproof sheet to switch between the covered state and the misaligned state.
[0059] In another embodiment of this application, the first limiting groove 12 and the switch piece 4 may be omitted, and the dustproof sheet may be switched between the covered state and the misaligned state only by the second limiting groove and the first protrusion 23.
[0060] In another embodiment of this application, a first limiting groove 12, a second limiting groove, and a switch piece 4 can be provided simultaneously. The dustproof sheet can be switched between the covered state and the misaligned state by the second limiting groove and the first protrusion 23, or the dustproof sheet can be switched between the covered state and the misaligned state by the second limiting groove 12 and the second protrusion 43.
[0061] In this embodiment of the application, the second limiting groove may not be provided, and the dustproof sheet may be switched between the covered state and the misaligned state by the second limiting groove 12 and the second protrusion 43.
[0062] In another embodiment of this application, the second limiting groove is an arc-shaped groove, and its specific parameters match the motion circumference corresponding to the first protrusion 23.
[0063] refer to Figure 6-7 In this embodiment of the application, the panel 1 includes a first outer shell 13 and a second outer shell 14 that are opposite to and connected. The first outer shell 13 is provided with a first opening 131, and the second outer shell 14 is provided with a second opening 141. The first opening 131 and the second opening 141 are correspondingly arranged to form an avoidance opening 11. The dustproof sheet 2 and the elastic member 3 are both disposed in the receiving space 15 formed by the first outer shell 13 and the second outer shell 14.
[0064] In a specific embodiment of this application, the first outer shell 13 and the second outer shell 14 are detachably connected.
[0065] In this embodiment of the application, by setting the panel 1 as a first housing 13 and a second housing 14, and by setting the dustproof sheet 2 and the elastic member 3 in the receiving space 15 formed between the first housing 13 and the second housing 14, the space occupied by the dustproof component is further reduced, and the installation and maintenance of the dustproof component are facilitated.
[0066] In this embodiment, the dustproof sheet 2 is connected to the first housing 13 via the first connection point 21, and the other end of the elastic member 3 is connected to the third connection point 17 on the first housing 13; the third connection point 17 is located within the accommodating space 15.
[0067] In this embodiment of the application, by connecting the dustproof sheet 2 and the elastic member 3 to the first housing 13 respectively, it is possible to facilitate the disassembly between the first housing 13 and the second housing 14, thereby facilitating the maintenance or replacement of the dustproof sheet 2 or the elastic member 3 and improving the reliability of the dustproof assembly.
[0068] In this embodiment of the application, the panel 1 is provided with a plurality of clearance openings 11, and the plurality of clearance openings 11 are correspondingly provided with a plurality of interfaces; the plurality of clearance openings 11 are respectively provided with dustproof components.
[0069] In a specific embodiment of this application, panel 1 includes a first outer shell 13 and a plurality of second outer shells 14. Specifically, the first outer shell 13 is provided with a plurality of first openings 131, and each second outer shell 14 is provided with a second opening 141. The plurality of first openings 131 and the plurality of second openings 141 are arranged in a one-to-one correspondence, thereby forming a plurality of clearance openings 11.
[0070] In this embodiment of the application, by setting multiple clearance openings 11, the dustproof component can protect multiple interfaces from dust at the same time, thereby improving the application range of the dustproof component.
[0071] The working principle of the dustproof component in the embodiments of this application is described below:
[0072] When the second connection point 22 is in the first position, the second protrusion 43 is controlled to slide from the first end to the second end in the first limiting groove 12, and the first protrusion 23 applies external force to the dustproof sheet 2, causing the position of the second connection point 22 to move between the second position and the third position; when the position of the second connection point 22 moves between the second position and the third position, the elastic member 3 provides a thrust, and the second connection point 22 can move to the third position under the thrust or the assistance of the thrust, and the dustproof sheet 2 changes from the covered state to the misaligned state, thereby exposing the interface.
[0073] When the second connection point 22 is in the third position, the second protrusion 43 is controlled to slide from the second end to the first end in the first limiting groove 12, and the first protrusion 23 applies external force to the dustproof sheet 2, and moves the position of the second connection point 22 between the second position and the first position; when the position of the second connection point 22 moves between the second position and the first position, the elastic member 3 provides a thrust, and the second connection point 22 can move to the first position under the thrust or the assistance of the thrust, and the dustproof sheet 2 changes from the misaligned state to the covered state, thereby concealing the interface.
[0074] The dustproof component in this application embodiment has the following beneficial effects:
[0075] By placing the dustproof sheet 2 on the panel 1, and allowing the dustproof sheet 2 to rotate at the first connection point 21 to change its state, specifically, the dustproof sheet 2 switches between a covered state that covers the avoidance opening 11 and a misaligned state that is not aligned with the avoidance opening 11, thereby achieving both shielding and exposure of the interface; at the same time, the elastic element 3 is connected to the second connection point 22 of the dustproof sheet 2, which can provide a restoring elastic force for the movement of the dustproof sheet 2; the above-mentioned dustproof assembly not only achieves dust protection for the test structure, but also reduces the space occupied by the dustproof assembly and avoids the loss of dustproof parts.
[0076] This application also provides an optical module testing device, which includes a test chamber, a fixture, and at least one dustproof component as described in this application embodiment; the fixture is disposed inside the test chamber and includes an interface for connecting to the optical module under test, with an clearance opening 11 corresponding to the interface.
[0077] In a specific embodiment of this application, the panel 1 of the dustproof component can be fixedly connected to the test chamber.
[0078] In a specific embodiment of this application, the test chamber and the fixture are detachably connected.

[0081] In a specific embodiment of this application, the bit error rate test board group is also called a BERT (Bit Error Rate Tester) board group. The bit error rate test board group is a circuit board that generates known data sequences and can generate high-quality, high-stability test signals. These signals are used to drive the test board (DUT, Device Under Test).
[0082] In a specific embodiment of this application, the test board and the bit error rate (BER) test board group are detachably connected, allowing for individual replacement of the test board and the BER test board group without requiring a complete replacement of the BER test board group and the test board itself. The replaceable test board can accommodate optical modules of different package types / sizes, improving test versatility. Furthermore, the BER test board group is relatively expensive, but eliminating the need for a complete replacement of the BER test board group and the test board significantly reduces costs. Moreover, the BER test board group employs a dual-board design, which significantly improves space utilization within the test enclosure, and the detachable low-speed signal board and high-speed signal board design also facilitates future equipment maintenance.
