[0030] The embodiments of the present application will be further described in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0031] In the specific technical features and embodiments described in the specific embodiments, any suitable combination can be combined without contradiction, for example, different specific technical features / embodiments can form different embodiments. In order to avoid unnecessary repetition, various possible combinations of each specific technical feature / embodiment in the present application are not described again.

[0032] In order to facilitate understanding of the vibration clamp 100 provided by the embodiments of the present application, the vibration device provided by the embodiments of the present application is described first:

[0033] The present application provides a vibration device, which comprises a vibration platform and the vibration clamp 100 in any embodiment of the present application, and the vibration clamp 100 is arranged on the vibration platform.

[0034] The circuit board is fixed on the vibration platform by the vibration clamp 100. The vibration platform can generate vibration, which is used to simulate that the circuit board is in a vibration working condition.

[0035] For example, when the vibration platform generates vibration, it is observed whether resonance occurs among the circuit board, the vibration clamp 100 and the vibration platform. If resonance occurs, the circuit board and the vibration clamp 100 need to be fixed again. If resonance does not occur, the circuit board is fixed firmly, and then the circuit board is tested.

[0036] In the related art, multiple scattered vibration clamps need to be arranged to fix the circuit board, and multiple scattered vibration clamps need to be rearranged to test different sizes of circuit boards, which is low in operation efficiency. Especially for irregularly shaped circuit boards, more vibration clamps need to be arranged, which is difficult to install and occupies more space.

[0037] In an embodiment, the vibration clamp 100 is used for fixing a circuit board, and the vibration clamp 100 comprises a plurality of fixing strips 10 and a first fastener. Figures 1 to 4 The plurality of fixing strips 10 are connected as a whole, each fixing strip 10 is rotationally connected with at least another fixing strip 10, and each fixing strip 10 is formed with a plurality of positioning holes 10a.

[0038] The first fastener is used for penetrating the positioning holes 10a and the circuit board, so as to fix the circuit board to the fixing strips 10.

[0039] The fixing strips 10 are formed with the plurality of positioning holes 10a, that is, the first fastener can penetrate any one of the positioning holes 10a, and the first fastener can selectively penetrate the positioning holes 10a and the fixing points of the circuit board.

[0040] The plurality of fixing strips 10 are connected as a whole, so as to improve the structural stability.

[0041] Each fixing strip 10 is rotationally connected with at least another fixing strip 10, that is, each fixing strip 10 can rotate, and the position of the fixing strip 10 is variable.

[0042] In an embodiment, the plurality of fixing strips 10 are sequentially connected in a ring structure. Figure 1 Figure 2 In an embodiment, the plurality of fixing strips 10 are sequentially connected in a strip structure.

[0043] In an embodiment, the plurality of fixing strips 10 are rotationally connected with another fixing strip 10 at the same end along the length direction.

[0044] In an embodiment, the plurality of fixing strips 10 are rotationally connected with two fixing strips 10 at two ends along the length direction.

[0045] In an embodiment, the plurality of fixing strips 10 are rotationally connected with two fixing strips 10 at two ends along the length direction.

[0046] ​The specific material of the fixing strip 10 is not limited, and the fixing strip 10 can be made of a metal material, for example, the fixing strip 10 can be an aluminum alloy structure, which has good structural strength and is easy to manufacture.

[0047] The specific type of the circuit board is not limited, and for example, the circuit board can be a printed circuit board (PCB). The first fastener includes, but is not limited to, a bolt or a screw, and the like.

[0048] It should be noted that in the present application, multiple means a number including two and more than two.

[0049] The vibration clamp 100 provided by the embodiment of the present application is provided with a plurality of positioning holes 10a formed in the fixing strip 10, and the plurality of fixing strips 10 are rotationally connected, each of the fixing strips 10 can rotate, and the position of the fixing strip 10 is variable. On the one hand, the first fastener can be selectively arranged in the positioning hole 10a and the fixed point of the circuit board, and the position of the fixing strip 10 can be adjusted by rotating the fixing strip 10, which can be suitable for circuit boards of different sizes. On the other hand, compared with the multiple clamps scattered in the related art, the plurality of fixing strips 10 are rotationally connected to form a single vibration clamp 100 in the present application, which can save the use space, and can also reduce the difficulty of fixing the circuit board and improve the work efficiency. In addition, the shape of the vibration clamp 100 can be changed by rotating the fixing strip 10, so that it can be suitable for irregular circuit boards, and the versatility of the vibration clamp 100 is improved.

[0050] In some embodiments, the vibration clamp 100 includes a first rotation shaft, and the first rotation shaft passes through all the fixing strips 10. That is, each of the fixing strips 10 can rotate around the first rotation shaft, the first rotation shaft plays a fixing role on the fixing strip 10, improves the structural stability of the vibration clamp 100, and also facilitates the user to rotate the fixing strip 10 to adjust the position of the fixing strip 10, and improves the work efficiency.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 , the plurality of fixing strips 10 are rotationally connected one by one. That is, the fixing strips 10 are connected two by two. For example, the vibration clamp 100 includes a plurality of second rotation shafts 20, and a single second rotation shaft 20 passes through two fixing strips 10.

[0052] For example, the first rotation shaft or the second rotation shaft 20 can pass through any part of the fixing strip 10 along the length direction. In an embodiment, the first rotation shaft or the second rotation shaft 20 can pass through one end of the fixing strip 10 along the length direction. In another embodiment, the first rotation shaft or the second rotation shaft 20 can pass through the middle part of the fixing strip 10.

[0053] The positioning hole 10a can be sized to fit the first fastener. The diameter of the positioning hole 10a is not limited, and in an embodiment, the diameter of the positioning hole 10a is between 2 mm and 3 mm. For example, the diameter of the positioning hole 10a can be 2 mm, 2.2 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.8 mm, or 3 mm, etc.

[0054] In some embodiments, the number of first fasteners is at least three, and each of the at least one positioning hole 10a of the fixing strip 10 is provided with a first fastener.

[0055] It should be noted that the at least three first fasteners do not overlap. That is, the circuit board is installed on the fixing strip 10 by a three-point fixing manner, so that the stability of the circuit board can be improved, and the circuit board can be prevented from loosening and shifting under the high-frequency vibration of the vibration platform.

[0056] For example, taking three first fasteners as an example, the three first fasteners are not on the same straight line, that is, the connection lines between the three first fasteners are approximately triangular, so that the stability of the circuit board can be further improved.

[0057] Each of the at least one positioning hole 10a of the fixing strip 10 is provided with a first fastener, that is, each of the fixing strips 10 can be connected with the circuit board, so that each of the fixing strips 10 can be fully utilized, and the connection stability of the circuit board and the vibration clamp 100 can be improved. For example, taking two fixing strips 10 and three first fasteners as an example: that is, two positioning holes 10a on one of the fixing strips 10 are respectively provided with a first fastener, and one positioning hole 10a on the other fixing strip 10 is provided with a first fastener. For example, taking three fixing strips 10 and three first fasteners as an example: that is, one positioning hole 10a on each of the fixing strips 10 is respectively provided with a first fastener.

[0058] In some embodiments, referring to Figures 1 to 3 , the vibration clamp 100 comprises a second fastener, and each of the fixing strips 10 is formed with a plurality of fixing holes 10b. The fixing hole 10b is used to pass through the second fastener to fix the fixing strip 10 to the vibration platform. The second fastener passing through the fixing hole 10b and the vibration platform can improve the connection stability of the vibration clamp 100 and the vibration platform, and prevent the vibration clamp 100 from loosening and shifting during the test.

[0059] The fixing strip 10 is formed with a plurality of fixing holes 10b, that is, the second fastener can pass through any one of the fixing holes 10b, and the second fastener can selectively pass through the fixing hole 10b and the fixing point of the vibration platform, so as to improve the space utilization of the vibration platform.

[0060] For example, the second fasteners can be multiple, and the multiple second fasteners are respectively arranged in the multiple fixing holes 10b, so as to enhance the connection stability of the vibration clamp 100 and the vibration platform.

[0061] The second fastener includes, but is not limited to, a bolt, a screw, or the like.

[0062] The fixing hole 10b can be sized to be adapted to the second fastener, and the diameter of the fixing hole 10b is not limited. In an embodiment, the diameter of the fixing hole 10b is between 12 mm and 13 mm. For example, the diameter of the fixing hole 10b can be 12 mm, 12.2 mm, 12.4 mm, 12.5 mm, 12.6 mm, 12.8 mm, or 13 mm, or the like.

[0063] In some embodiments, the number of the second fasteners is at least three, and each fixing strip 10 has at least one fixing hole 10b arranged with the second fastener.

[0064] It should be noted that the at least three second fasteners are not overlapped. That is, the fixing strip 10 is installed on the vibration platform in a three-point fixed manner, so as to enhance the stability of the vibration clamp 100 and prevent the vibration clamp 100 from loosening and shifting under the high-frequency vibration of the vibration platform.

[0065] For example, in the case of three second fasteners, the three second fasteners are not on the same straight line, that is, the connecting lines between the three second fasteners are approximately triangular, so as to further enhance the stability of the vibration clamp 100.

[0066] Each fixing strip 10 has at least one fixing hole 10b arranged with the second fastener, that is, each fixing strip 10 can be connected to the vibration platform, so as to fully utilize each fixing strip 10 and enhance the connection stability of the vibration clamp 100 and the vibration platform. For example, in the case of two fixing strips 10 and three second fasteners, that is, two fixing holes 10b on one of the fixing strips 10 are respectively arranged with the second fasteners, and one fixing hole 10b on the other fixing strip 10 is arranged with the second fastener. For example, in the case of three fixing strips 10 and three second fasteners, that is, one fixing hole 10b on each fixing strip 10 is respectively arranged with the second fastener.

[0067] In some embodiments, referring to Figures 1 to 3 The multiple fixing holes 10b and the multiple positioning holes 10a of each fixing strip 10 are alternately and spacedly arranged along the length direction. In this way, the first fastener is arranged in the positioning hole 10a and the circuit board, and the second fastener is arranged in the fixing hole 10b and the vibration platform, so as to reduce the installation difficulty.

[0068] Exemplarily, at least one fixing hole 10b of each fixing strip 10 is spaced apart from the circuit board, so that the second fastener is spaced apart from the circuit board, and contact between the second fastener and the circuit board can be prevented, and damage to the circuit board under high-frequency vibration of the vibration platform can be avoided to a certain extent.

[0069] In some embodiments, referring to Figure 3 , two positioning holes 10a are distributed on both sides of the fixing hole 10b along the width direction, and the width direction intersects the length direction. Exemplarily, the width direction can be perpendicular to the length direction.

[0070] In some embodiments, referring to Figure 1 and Figure 2 , the end portions of the at least three fixing strips 10 are sequentially connected to form a polygonal structure along the length direction. Exemplarily, the end portions of the four fixing strips 10 are sequentially connected to form a quadrilateral structure along the length direction, that is, the end portions of the four fixing strips 10 are sequentially connected end to end to form a quadrilateral structure along the length direction, so that the structural stability of the vibration clamp 100 can be improved.

[0071] It should be noted that, in the present application, at least three means three or more than three. A single vibration clamp 100 of the present application can be used to fix one circuit board or multiple circuit boards.

[0072] Continuously referring to Figure 1 and Figure 2 , the vibration clamp 100 in the quadrilateral structure can fix at least two circuit boards. For example, two circuit boards are fixed on two adjacent fixing strips 10, that is, each circuit board is provided with two first fasteners penetrating the one fixing strip 10 and one first fastener penetrating the other fixing strip 10. For another example, two circuit boards are fixed on three fixing strips 10, that is, the two circuit boards are partially fixed on two opposite fixing strips 10, and each circuit board is provided with one first fastener penetrating each of the three fixing strips 10. In this way, two circuit boards can be fixed by one vibration clamp 100, so that the number of vibration clamps 100 used can be reduced in the case of simultaneously detecting multiple circuit boards, the occupied space can be reduced, and the production cost can be reduced.

[0073] In other embodiments, the end portions of the at least three fixing strips 10 are sequentially connected to form a strip-shaped structure along the length direction.

[0074] In some embodiments, referring to Figure 2 , the included angle between the two adjacent fixing strips 10 is between 5° and 175°. In this way, by setting a suitable angle, the vibration clamp 100 can fix circuit boards of different sizes and irregular shapes, and the versatility of the vibration clamp 100 can be improved.

[0075] For example, the angle between two adjacent fixing bars 10 can be 5°, 20°, 45°, 60°, 75°, 90°, 135°, or 175°, etc.

[0076] In some embodiments, referring to Figure 3 and Figure 4 , the fixing bar 10 comprises a main body 11 and a fixing ear 12, the fixing ear 12 is connected to one end of the main body 11 along the length direction, the main body 11 is formed with a limiting slot 10c at the end away from the fixing ear 12 along the length direction, the fixing ear 12 of one fixing bar 10 is accommodated in the limiting slot 10c of the other fixing bar 10, and the two are rotationally connected. In this way, the fixing ear 12 can be regarded as the male head of the fixing bar 10, the limiting slot 10c can be regarded as the female head of the fixing bar 10, the limiting slot 10c plays a positioning and fixing role on the fixing ear 12, and the assembly difficulty of the vibration clamp 100 can be reduced.

[0077] For example, referring to Figure 1 and Figure 2 , the second rotation shaft 20 penetrates the limiting slot 10c of each fixing bar 10 and the fixing ear 12 of the adjacent fixing bar 10.

[0078] In some embodiments, referring to Figure 4 , the thickness of the fixing ear 12 is less than the thickness of the main body 11. For example, the positioning hole 10a and the fixing hole 10b are both formed in the main body 11. In this way, in the thickness direction, the fixing ear 12 does not protrude from the surface of the main body 11, the surface of the main body 11 is relatively flat, the circuit board can be relatively stably fixed on the fixing bar 10, and the vibration clamp 100 can be relatively stably fixed on the vibration platform.

[0079] In some embodiments, referring to Figure 4 , in the thickness direction, the surfaces of the main bodies 11 of the plurality of fixing bars 10 are flush. For example, the surfaces of the main bodies 11 of the respective fixing bars 10 are flush. That is to say, the surfaces of all the fixing bars 10 are relatively flat, preventing the fixing bars 10 from being locally protruded to mistakenly touch the circuit board and cause damage, and also allowing the circuit board to be relatively stably fixed on the fixing bar 10, and the vibration clamp 100 to be relatively stably fixed on the vibration platform.

[0080] In some embodiments, the fixing bar 10 is an integrally formed structure, which is easy to produce.

[0081] In some embodiments, the length of at least one fixing bar 10 is not equal to the length of the other fixing bars 10, which facilitates the vibration clamp 100 to fix the circuit board of irregular shape and improves the versatility of the vibration clamp 100.

[0082] In some embodiments, the lengths of all the fixed strips 10 can be the same. In this way, the manufacturing difficulty is reduced and the production efficiency is improved.
