Light-shielding mechanism for test apparatus, and test apparatus

Abstract

Disclosed in the present application are a light-shielding mechanism for a test apparatus, and a test apparatus. The light-shielding mechanism comprises: a cover, in which an accommodating space is defined, a first opening being formed on one side of the cover; and a door, which is movably connected to the cover and selectively opens or closes the first opening. A second opening is formed on at least some of side plates of the cover; the second opening is covered by a shielding curtain assembly; and the shielding curtain assembly comprises a plurality of shielding curtains which are arranged in sequence in the same direction, at least some of the shielding curtains each being configured to move or deform in a direction away from other shielding curtains that are adjacent thereto, such that a cable passing gap between the shielding curtain and the other shielding curtains that are adjacent thereto is formed, the cable passing gap being in communication with the accommodating space. By means of the cable passing gap, a cable of the test apparatus can pass therethrough, such that a relatively large light transmission area cannot be formed at the shielding curtain assembly, and thus the part of the test apparatus that needs to be shielded can be effectively shielded, thereby facilitating the improvement of the test precision of the test apparatus, and therefore the cabling of the test apparatus is organized.

[0034] The shading mechanism provided in the embodiment of the present application can be used for testing equipment, which can be a transmission line pulse (or TLP) testing equipment or other testing equipment with anti-exposure requirements.

[0035] The embodiments will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0036] Figure 1 is a structural schematic diagram of a shading mechanism for testing equipment provided in one embodiment of the present application, Figure 2 is a schematic diagram of the decomposed structure of the shading mechanism shown in Figure 1, and Figure 3 is a structural schematic diagram of a shading mechanism for testing equipment provided in another embodiment of the present application. Referring to Figures 1 to 3, the shading mechanism 100 for testing equipment provided in an embodiment of the present application includes a cover body 10 and a door body 20. The interior of the cover body 10 defines a containing space 11, and one side of the cover body 10 is provided with a first opening 12, and the first opening 12 is connected to the containing space 11. The door body 20 is movably connected to the cover body 10, and the door body 20 is configured to selectively open or close the first opening 12.

[0037] The cover body 10 may include multiple side panels for enclosing a accommodating space 11. At least some of the side panels of the cover body 10 are provided with a second opening 13. The second opening 13 is covered by a curtain assembly 30. The curtain assembly 30 includes multiple blocking curtains 31 arranged successively in the same direction. At least some of the blocking curtains 31 are configured to be able to move or deform in a direction away from other adjacent blocking curtains 31 to form a line gap between the blocking curtains 31 and other adjacent blocking curtains 31, and the line gap is connected to the accommodating space 11.

[0038] It should be noted that any structure of the shading mechanism 100 is a light-proof structure made of light-proof material. For example, each side panel of the cover body 10, the door body 20 and each shielding curtain 31 of the curtain assembly 30 are all light-proof components.

[0039] One side of the cover body 10 may be completely opened to form a first opening 12 . In this case, the cover body 10 does not have a side panel on this side.

[0040] One side of the cover body 10 may also be partially opened to form a first opening 12 . In this case, the cover body 10 is provided with a side panel on the side, and the first opening 12 is formed on the side panel.

[0041] The number of the door body 20 may be one, or two or more.

[0042] The connection between the door body 20 and the cover body 10 includes, but is not limited to, pivot connection, sliding connection, plug connection, etc.

[0043] For example, there are two door bodies 20 , and the two door bodies 20 are pivotally connected to the cover body 10 in a double-door manner, so as to facilitate door opening and closing operations.

[0044] The second opening 13 may be provided at one end of the side plate of the cover body 10 (refer to the embodiment shown in FIG1 ), or may be provided at the middle of the side plate of the cover body 10 (refer to the embodiment shown in FIG3 ).

[0045] When the blind assembly 30 does not form a through-line slit, the blind assembly 30 is continuous as a whole, without any gaps or slits. The blind assembly 30 covering the second opening 13 means that when the blind assembly 30 does not form a through-line slit, the second opening 13 is completely blocked by the blind assembly 30, and external light does not enter the interior of the shading mechanism 100 through the second opening 13.

[0046] Optionally, the blinds 31 are operable to move or deform. During testing, a force may be manually applied to at least a portion of the blinds 31 of the blind assembly 30 to cause at least a portion of the blinds 31 to move or deform away from an adjacent blind 31, thereby forming a cable gap to allow a cable of a test device to pass through the cable gap.

[0047] Optionally, the shade curtain 31 can also be controlled to move or deform. In this case, the shading mechanism 100 also includes a drive mechanism for driving the shade curtain 31 to move or deform. During testing, the drive mechanism can be controlled to start and operate, thereby driving the shade curtain 31 to move or deform to form a cable gap, allowing the cable of the test equipment to pass through the cable gap.

[0048] When the force causing the shielding curtain 31 to move or deform disappears, the shielding curtain 31 can return to its initial state. In the initial state, the shielding curtain assembly 30 forms a continuous and complete shielding body to completely shield the second opening 13 .

[0049] Optionally, the plurality of shielding curtains 31 of the curtain assembly 30 may include fixed shielding curtains and movable shielding curtains, wherein the fixed shielding curtains are fixed relative to the cover body 10 and cannot move or deform relative to the cover body 10, while the movable shielding curtains can move or deform relative to the cover body 10, and the movement or deformation of the movable shielding curtains can form a wire gap. The fixed shielding curtains and the movable shielding curtains can be arranged one by one or in an unfixed number of alternating positions.

[0050] Optionally, all of the multiple shielding curtains 31 of the shielding curtain assembly 30 may be movable or deformable shielding curtains 31 .

[0051] The shading mechanism 100 for testing equipment provided in an embodiment of the present application includes a housing 10 and a door 20. The housing 10 defines a receiving space 11 therein, and a first opening 12 is provided on one side of the housing 10. The door 20 is movably connected to the housing 10 and can selectively open or close the first opening 12. When the door 20 opens the first opening 12, the exposure-proof portion of the testing equipment that needs to be shielded can be placed into the receiving space 11 through the first opening 12, and the operator can operate or adjust the testing equipment located in the receiving space 11 through the first opening 12. At least part of the side panel of the housing 10 is provided with a second opening 13, which is covered by a curtain assembly 30. The curtain assembly 30 includes a plurality of shielding curtains 31 arranged successively in the same direction, and at least part of the shielding curtains 31 can move or deform away from other adjacent shielding curtains 31, thereby forming a line gap between the partial shielding curtain 31 and the other adjacent shielding curtains 31. During testing, the door body 20 closes the first opening 12, and the exposable part of the test equipment that does not need to be shielded can be arranged outside the shading mechanism 100, and the anti-exposure part of the test equipment that needs to be shielded can be arranged inside the shading mechanism 100. The exposable part and the anti-exposure part are connected by a cable to facilitate signal transmission. The cable passes through the wire gap of the curtain assembly 30 and will not form a large light-transmitting area at the curtain assembly 30. Therefore, the shading mechanism 100 can effectively block the anti-exposure part of the test equipment that needs to be shielded, which is beneficial to improving the test accuracy of the test equipment.

[0052] On the other hand, the embodiment of the present application provides a curtain assembly 30 on the cover body 10, so that the cables between the part of the test equipment inside the shading mechanism and the part outside the shading mechanism pass through the curtain assembly 30, which can limit the cables to the side and area where the curtain assembly 30 is located. To a certain extent, the routing of the test equipment is regularized, the problem of too messy test routing is solved, and it is conducive to the smooth progress of teaching and training work.

[0053] FIG4 is a schematic diagram of another orientation of the blind assembly of the shading mechanism shown in FIG1. ​​In some embodiments, referring to FIG4, at least partially adjacent two blinds 31 are arranged to overlap. That is, at least partially adjacent two blinds 31 have adjacent areas that overlap. The adjacent area of ​​two blinds 31 refers to the area where the two blinds 31 are adjacent to each other.

[0054] In the embodiment of the present application, at least partially adjacent two shielding curtains 31 are overlapped. Even if the shielding curtain 31 is accidentally moved or deformed to a certain extent by external force, it will not cause a light leakage area in the shielding curtain assembly 30, thereby improving the light blocking reliability of the shielding curtain assembly 30.

[0055] Optionally, the plurality of shielding curtains 31 of the curtain assembly 30 are arranged to overlap in sequence along the same direction, that is, any two adjacent shielding curtains 31 overlap, further improving the light-shielding reliability of the curtain assembly 30 .

[0056] Optionally, the plurality of shielding curtains 31 in the middle of the shade assembly 30 are arranged in an overlapping manner. The middle position of the shade assembly 30 is a commonly used cross-line position. In the embodiment of the present application, only the plurality of shielding curtains 31 in the middle are arranged in an overlapping manner. This not only ensures that the shade assembly 30 has good light-blocking reliability, but also reduces the number of shielding curtains 31, simplifies the structure of the light-blocking mechanism 100, and reduces its cost.

[0057] In other embodiments, at least partially adjacent two shielding curtains 31 of the curtain assembly 30 may also be arranged adjacent to each other, that is, adjacent sides of the two adjacent shielding curtains 31 are arranged close to or in contact with each other.

[0058] In some embodiments, at least part of the shielding curtains 31 are deformable soft curtains. That is, each shielding curtain 31 can be deformed in an operative or controllable manner. It is understandable that the deformation of the shielding curtain 31 can be a local deformation, thereby reducing the size of the wire gap formed between two adjacent shielding curtains 31 as much as possible, thereby improving the shading effect. Exemplarily, after the shielding curtain 31 is deformed, the wire gap formed between two adjacent shielding curtains 31 can be an eye-shaped gap that allows cables to pass through, rather than a strip-shaped gap.

[0059] In the embodiment of the present application, the shielding curtain 31 is configured as a soft curtain so that the shielding curtain 31 generates a line gap in a deformed manner, which can reduce the size of the line gap and thus improve the shading effect.

[0060] Optionally, when the shielding curtain 31 includes a fixed shielding curtain and a movable shielding curtain, the movable shielding curtain may be a soft curtain, and the fixed shielding curtain may be a soft curtain or a hard curtain.

[0061] In some embodiments, referring to FIG. 1 , the blind assembly 30 is disposed on one side of the side panel along a first direction X, the first direction X being parallel to the vertical direction, and the shielding curtain 31 is suspended below the side panel.

[0062] It can be understood that the arrangement direction of the plurality of shielding curtains 31 of the curtain assembly 30 is perpendicular to the first direction X. That is, the plurality of shielding curtains 31 are arranged successively along a direction parallel to the horizontal direction.

[0063] The curtain assembly 30 can be arranged on the lower side of the side panel along the first direction X, the upper end of the shielding curtain 31 along the first direction X can be connected to the side panel, and the lower end of the shielding curtain 31 along the first direction X can be freely arranged to facilitate the movement or deformation of the shielding curtain 31.

[0064] The housing 10 may include a first side panel 14 and at least one second side panel 15. The at least one second side panel 15 is connected to one side of the first side panel 14 along the first direction X and encloses the first side panel 14 to form a housing space 11. The second opening 13 is provided on the lower side of the second side panel 15 along the first direction X to facilitate a cantilevered arrangement.

[0065] In the embodiment of the present application, the shielding curtain 31 is suspended below the side panel, and the movement space and / or deformation space of the shielding curtain 31 is larger. The movement or deformation of the shielding curtain 31 is more flexible, which is convenient for threading the cables of the test equipment and reduces the difficulty of the threading operation.

[0066] In other embodiments, referring to FIG3 , the curtain assembly 30 may also be provided in the middle of the side panel along the first direction X. In this case, a second opening 13 is formed in the middle of the side panel along the first direction X, and the second opening 13 is in the form of a window. When the first direction X is parallel to the vertical direction, some of the shielding curtains 31 may be suspended at the second opening 13, while the remaining shielding curtains 31 are fixed at the second opening 13. Alternatively, all of the shielding curtains 31 may be suspended at the second opening 13. Of course, all of the shielding curtains 31 may also be fixed at the second opening 13, in which case a cross-line gap may be generated by the deformation of the shielding curtains 31. When the first direction X is parallel to the horizontal direction, the shielding curtains 31 cannot be suspended, and each shielding curtain 31 is fixed at the second opening 13. In this case, a cross-line gap may be generated by the deformation of the shielding curtains 31.

[0067] In some embodiments, the height of the blind assembly 30 along the first direction X is 20-50 cm. For example, the height of the blind assembly 30 along the first direction X can be 20 cm, 25 cm, 30 cm, 35 cm, 40 cm, 45 cm or 50 cm.

[0068] It can be understood that the height of the curtain assembly 30 along the first direction X is the same as the height of each shielding curtain 31 along the first direction X, which is the distance between the upper end of the shielding curtain 31 and the bottom of the cover body 10.

[0069] In the embodiment of the present application, the height of the curtain assembly 30 along the first direction X is set between 20 and 50 cm, which makes the shading mechanism 100 suitable for wiring of most types of test equipment, shortens the wiring path and wiring length, and is conducive to neatness and regularity of test wiring.

[0070] In some embodiments, the width of the curtain assembly 30 along the arrangement direction of the plurality of shielding curtains 31 is 50 to 100 cm. For example, the width of the curtain assembly 30 along the arrangement direction of the plurality of shielding curtains 31 can be 50 cm, 55 cm, 60 cm, 65 cm, 70 cm, 75 cm, 80 cm, 85 cm, 90 cm, 95 cm, or 100 cm.

[0071] The plurality of shielding curtains 31 may be arranged successively along the third direction Z. In an undeformed state, each shielding curtain 31 may be in a strip-shaped structure extending along the first direction X, where the first direction X and the third direction Z intersect.

[0072] The width of the curtain assembly 30 along the third direction Z can be the length of the space occupied by multiple shielding curtains 31 in the third direction Z after being arranged along the third direction Z. The width of the curtain assembly 30 along the third direction Z may be equal to or less than the sum of the widths of the multiple shielding curtains 31 along the third direction Z.

[0073] The width of the blind assembly 30 along the arrangement direction of the plurality of blinds 31 may be equal to or slightly larger than the width of the second opening 13 along the arrangement direction of the plurality of blinds 31 .

[0074] Optionally, the width of the curtain assembly 30 along the arrangement direction of the multiple shielding curtains 31 may be the same as the width of the side panel along the arrangement direction of the multiple shielding curtains 31. In this case, the second opening 13 may extend from one end of the side panel along the arrangement direction of the multiple shielding curtains 31 to the other end in this direction.

[0075] Optionally, the width of the curtain assembly 30 along the arrangement direction of the multiple shielding curtains 31 may also be smaller than the width of the side panel along the arrangement direction of the multiple shielding curtains 31. In this case, the second opening 13 is located in the middle of the side panel along the arrangement direction of the multiple shielding curtains 31.

[0076] In some embodiments, the cover body 10 includes a first side panel 14 and at least one second side panel 15, the at least one second side panel 15 is connected to one side of the first side panel 14 along the first direction X, and is enclosed with the first side panel 14 to form a accommodating space 11, the first opening 12 is formed on the second side panel 15 or the first opening 12 is adjacent to at least part of the second side panel 15, and the second opening 13 is provided on the second side panel 15.

[0077] The number of the second side plate 15 may be one. In this case, the second side plate 15 may be an arc-shaped plate or an annular plate, and the cover body 10 may be a hollow columnar structure.

[0078] There may be multiple second side panels 15 , and each second side panel 15 is a flat plate structure, while the cover body 10 is a hollow prismatic structure.

[0079] The first opening 12 may be formed in the second side plate 15 , that is, the first opening 12 is opened on the second side plate 15 , and the first opening 12 is a gap formed by removing a portion of the second side plate 15 .

[0080] The first opening 12 may also be adjacent to at least a portion of the second side plate 15. For example, when there is only one second side plate 15, the second side plate 15 may be an arcuate plate with both ends of the arcuate plate spaced apart in the circumferential direction to form the first opening 12. For example, when there are multiple second side plates 15, the first opening 12 may be formed between two of the second side plates 15.

[0081] The second opening 13 is provided on the second side plate 15 to facilitate wiring from the side of the cover body 10 for easy operation. The second opening 13 can be a notch area formed by cutting out a portion of the second side plate 15.

[0082] In some embodiments, the at least one second side panel 15 includes three second side panels 15 , which are sequentially connected to form a U-shaped structure. Two second side panels 15 are disposed opposite each other along a second direction Y, and the first opening 12 is disposed opposite another second side panel 15 along a third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. Each second side panel 15 is provided with a second opening 13 , and the curtain assembly 30 covered by each second opening 13 has the same height.

[0083] Optionally, the first direction X may be parallel to the vertical direction, and the second direction Y and the third direction Z may be parallel to the horizontal direction.

[0084] Each of the three second side panels 15 is provided with a curtain assembly 30, which can simultaneously lead out cables in three different directions of the shading mechanism 100, thereby connecting different test equipment or connecting different functional modules of the same test equipment, making it convenient to separate the cables of different test equipment or the cables of different functional modules of the same test equipment, and making the cable partitioning clearer and more regular.

[0085] The heights of the curtain assemblies 30 on each second side panel 15 are the same, which makes it convenient for the anti-exposure part in the shading mechanism 100 to connect cables of different testing equipment or cables with different functions of the same testing equipment at the same height, which is conducive to the position selection of the anti-exposure part.

[0086] In some embodiments, the cover body 10 further includes a support frame 16 , the first side panel 14 , the second side panel 15 and the door body 20 are all connected to the support frame 16 , and the curtain assembly 30 is connected to the second side panel 15 and / or the support frame 16 .

[0087] The support frame 16 can provide support for the side panels, door body 20 and other structures of the cover body 10, making it easy to flexibly select the position of the curtain assembly 30 on the side panels.

[0088] For example, when the second openings 13 on the three second side panels 15 are all located at the bottom of the second side panels 15 so that the multiple shielding curtains 31 are all suspended below the second side panels 15, and the width of the second openings 13 along the arrangement direction of the multiple shielding curtains 31 is consistent with the width of the second side panels 15 in this direction, the support frame 16 can play an effective supporting role.

[0089] The support frame 16 may include a plurality of vertical legs extending vertically and a plurality of transverse legs extending horizontally.

[0090] In some embodiments, the housing 10 further includes a third opening disposed opposite the first side panel 14 along the first direction X. In the test mode, the third opening is located below the first side panel 14. In the test mode, the shading mechanism 100 can be placed on the ground or a tabletop, and the third opening can be blocked by the ground or tabletop to prevent external light from entering the shading mechanism 100 through the third opening.

[0091] In the embodiment of the present application, a third opening is provided on a side of the cover body 10 opposite to the first side plate 14 along the first direction X, which can save material of the cover body 10 and reduce the weight of the cover body 10.

[0092] According to the second aspect of the present application, an embodiment of the present application further provides a test device. Figure 5 is a structural diagram of a test device provided by an embodiment of the present application. Referring to Figure 5, the test device 1 provided by an embodiment of the present application includes a shading mechanism 100 and a transmission line pulse tester 200 provided in any of the above embodiments. The exposable portion 210 of the transmission line pulse tester 200 is arranged outside the shading mechanism 100, and the anti-exposure portion 220 of the transmission line pulse tester 200 is arranged in the accommodating space 11 of the shading mechanism 100. The exposable portion 210 and the anti-exposure portion 220 are connected by a cable 230 passing through the wire gap of the shading mechanism 100.

[0093] The exposable portion 210 of the transmission line pulse tester 200 is a portion that can be exposed to the external environment and does not require light shielding. For example, the exposable portion 210 may include a display, an operation panel, and the like.

[0094] The anti-exposure portion 220 of the transmission line pulse tester 200 is a portion that cannot be exposed to the external environment and needs to be shielded from light. For example, the anti-exposure portion 220 may include a test wafer or the like.

[0095] When the test equipment 1 is being tested, the door body 20 closes the first opening 12, and the exposable part 210 of the test equipment 1 that does not require shading can be arranged outside the shading mechanism 100, and the anti-exposure part 220 of the test equipment 1 that requires shading can be arranged inside the shading mechanism 100. The exposable part 210 and the anti-exposure part 220 are connected by a cable 230 to facilitate signal transmission. The cable 230 passes through the wire gap of the curtain assembly 30 and will not form a large light-transmitting area at the curtain assembly 30. Therefore, the anti-exposure part 220 of the test equipment 1 that requires shading has a better shading effect, thereby improving the test accuracy of the test equipment 1.

[0096] On the other hand, the embodiment of the present application provides a curtain assembly 30 on the cover body 10, so that the cable 230 between the anti-exposure part 220 of the test equipment 1 inside the shading mechanism 100 and the exposable part 210 outside the shading mechanism 100 passes through the curtain assembly 30, and the cable 230 can be restricted to the side and area where the curtain assembly 30 is located, which to a certain extent regularizes the routing of the test equipment 1, solves the problem of too messy test routing, and is conducive to the smooth progress of teaching and training.

[0097] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
