Description

Technical Field

[0001] This application relates to the field of power supply equipment testing technology, and in particular to a clamping device. Background Technology

[0002] A power supply is a device that can provide electrical energy. After the power supply is manufactured, it needs to undergo a series of tests, mainly to ensure that the power supply can output stably under various working conditions. Power supply testing generally includes testing for high temperature, low temperature, high temperature and high humidity, live operation, voltage, load, temperature and transient response, etc. The above test methods and technologies are used to evaluate the power supply to ensure that it can operate efficiently, reliably and stably when it is actually used in the factory.

[0003] During power supply testing, the equipment needs to be secured to ensure the accuracy and reliability of the test results. Traditionally, power supplies are secured using screws, studs, etc. However, in the actual installation of aviation power supplies, there are strict space requirements, so the power board can only be secured by clamping its edges.

[0004] However, in the process of implementing this application, the applicant discovered that the current operating method is generally to use clamping plates for fixation, that is, to clamp the power supply device from both sides. If the clamping of the power supply device is too tight, it will squeeze the sides of the power supply device and cause the power supply device to deform. If the clamping is too loose, the fixing effect of the power supply device is not enough, resulting in the displacement of the power supply position. Utility Model Content

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0023] Unless otherwise specified, the term "multiple" in this application refers to two or more.

[0024] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please see Figures 1 to 3 This application provides a clamping device for fixing a power supply for testing. The clamping device includes a base 10, a first fixing plate 20, a first adjusting component 30, and a second adjusting component 40. The base 10 supports the power supply. The first fixing plate 20 is vertically connected to the base 10 and abuts against a first side of the power supply. The first adjusting component 30 includes a first clamping plate 310, which is parallel to the first fixing plate 20 and slidably connected to the base 10 along a first direction x. The first clamping plate 310 abuts against a second side of the power supply. The second adjusting component 40 includes a second clamping plate 410, which is slidably connected to the first fixing plate 20 along a second direction y and is parallel to the base 10. The first direction x and the second direction y are perpendicular to each other. The first clamping plate 310 cooperates with the first fixing plate 20 to clamp the side of the power supply to restrict the power supply from moving along the first direction x. The second clamping plate 410 cooperates with the base 10 to clamp the top and bottom of the power supply to restrict the power supply from moving along the second direction y. The power supply is locked from two directions, reducing the risk of the power supply shifting.

[0026] In some embodiments, the base 10 includes a bottom plate 110 and a back plate 120 connected to each other, with the bottom plate 110 and the back plate 120 vertically connected. The bottom plate 110 abuts against the bottom of the power supply, and the back plate 120 abuts against the back of the power supply. It should be noted that the first side of the power supply is opposite to the second side, and the bottom of the power supply is opposite to the top.

[0027] For ease of description, the length direction of the base plate 110 is defined as the first direction x, the height direction of the base plate 110 is defined as the second direction y, and the width direction of the base plate 110 is defined as the third direction z. The first direction x, the second direction y, and the third direction z are all perpendicular to each other.

[0028] In some embodiments, the first fixing plate 20 is perpendicularly connected to the base plate 110 along the second direction y, and perpendicular to the back plate 120 along the third direction z. The first clamping plate 310 is slidably connected to the base plate 110, and the second clamping plate 410 is parallel to the base plate 110.

[0029] In some embodiments, the base plate 110 is provided with a first groove 111 along a first direction x, and the first clamping plate 310 is slidably connected to the first groove 111. Specifically, a first slider 320 is connected to one end of the first clamping plate 310 near the first groove 111, and the first slider 320 is slidably connected to the first groove 111. The first slider 320 makes the first clamping plate 310 slide more smoothly.

[0030] In some embodiments, the first slider 320 and the first clamping plate 310 are integrally formed.

[0031] In some embodiments, such as Figure 3 As shown, along the first direction x, the first end of the first slide groove 111 is fixed to the first fixed plate 20, and the second end of the first slide groove 111 is provided with a first stop 112. The first slider 320 slides between the first fixed plate 20 and the first stop 112. The first stop 112 is used to prevent the first slider 320 from disengaging from the first slide groove 111.

[0032] In some embodiments, the first stop 112 is integrally formed with the base plate 110.

[0033] In some embodiments, along the third direction z, the width of the opening of the first groove 111 is smaller than the width of the bottom of the groove, so as to prevent the first slider 320 from sliding out along the second direction.

[0034] In some embodiments, the first adjusting assembly 30 includes a first elastic element 330, which is disposed within the first sliding groove 111 and located between the first stop 112 and the first slider 320. When the power supply is clamped between the first fixing plate 20 and the first clamping plate 310, the first elastic element 330 is in a compressed state, thereby causing the elastic force of the first elastic element 330 to drive the first clamping plate 310 to abut against the second side of the power supply. The first elastic element 330 automatically adjusts the clamping force, reducing the risk of power supply deformation due to excessive clamping force.

[0035] In some embodiments, the first elastic element 330 is a spring. Specifically, the first adjusting assembly 30 includes a moving rod 340. Along a first direction x, the first end of the moving rod 340 is connected to the end of the first slider 320 away from the first fixed plate 20, and the second end of the moving rod 340 passes through the first stop member 112. The moving rod 340 can move along the first slide groove 111 with the first slider 320, and the first elastic element 330 is sleeved on the moving rod 340. The moving rod 340 increases the stability of the sliding of the first clamping plate 310 on the one hand, and guides the first elastic element 330 on the other hand, reducing the risk of tilting during the movement of the first elastic element 330, which is beneficial to improving the clamping effect of the first clamping plate 310.

[0036] In some embodiments, the first adjustment assembly 30 includes a first locking member 350, which restricts the movement of the first slider 320, the moving rod 340, or the first clamping plate 310 when the first clamping plate 310 abuts against the second side of the power source.

[0037] In some embodiments, one end of the first locking member 350 is fixed to the back plate 120, and the other end of the first locking member 340 is operable to clamp or release the first clamping plate 310. When the first clamping plate 310 abuts against the second side of the power supply, the first locking member 350 clamps the first clamping plate 310 to restrict the movement of the first clamping plate 310, and when it is necessary to remove the power supply from the clamping device, the first locking member 350 releases the first clamping plate 310.

[0038] In some embodiments, the first locking member 350 is movably connected to the moving rod 340. Specifically, the first locking member 350 is a locking nut, the outer periphery of the moving rod 340 is provided with external threads, and the first locking member 350 is threadedly connected to the moving rod 340. When the first clamping plate 310 abuts against the second side of the power supply, the first locking member 350 is tightened to abut against the first stop member 112 to restrict the movement of the moving rod 340 and the first clamping plate 310. When it is necessary to remove the power supply from the clamping device, the first locking member 350 is loosened to a preset distance or the moving rod 340 is directly unscrewed.

[0039] It should be noted that the aforementioned preset distance refers to the distance that the power supply can move unimpeded (except for the elastic force of the first elastic element) between the first fixed plate 20 and the first clamping plate 310 along the first direction x.

[0040] In this embodiment, the first locking member 350 is movably connected to the second end of the first slide groove 111. The first locking member 350 is configured to operably abut or release the moving rod 340. For example, the first locking member 350 is movably connected to the first stop member 112. Specifically, the first locking member 350 is a locking bolt, and the first locking member 350 is threadedly connected to the first stop member 112. When the first clamping plate 310 abuts against the second side of the power supply, the first locking member 350 is tightened to abut against the moving rod 340 to restrict the movement of the moving rod 340 and the first clamping plate 310. When it is necessary to remove the power supply from the clamping device, the first locking member 350 releases the moving rod 340, that is, the first locking member 350 is loosened to disengage from the moving rod 340. It can be understood that the first stop member 112 has a threaded hole, and the first locking member 350 is threadedly connected to this threaded hole. Alternatively, a second fixing plate 130 may be provided at the end of the base plate 110 away from the first fixing plate 20, and the first locking member 350 may be movably connected to the second fixing plate 130. Specifically, the first locking member 350 is a locking bolt, and the first locking member 350 is threadedly connected to the second fixing plate 130. When the first clamping plate 310 abuts against the second side of the power supply, the first locking member 350 is tightened to abut against the moving rod 340 to restrict the movement of the moving rod 340 and the first clamping plate 310. When it is necessary to remove the power supply from the clamping device, the first locking member 350 releases the moving rod 340, that is, the first locking member 350 is loosened to disengage from the moving rod 340. It can be understood that a threaded hole is passed through the second fixing plate 130, and the second locking member 450 is threadedly connected to the threaded hole.

[0041] In some embodiments, the second end of the moving rod 340 is provided with a stop block 360, which is used to restrict the moving rod 340 from being fully retracted into the first slide groove 111.

[0042] In some embodiments, the first fixing plate 20 is provided with a second sliding groove 210 along the second direction y, the first clamping plate 310 is provided with a third sliding groove 311 along the second direction y, the second clamping plate 410 is provided with a second slider 420 at one end near the first fixing plate 20, and a third slider 430 at one end near the first clamping plate 310. The second slider 420 is slidably connected to the second sliding groove 210, and the third slider 430 is slidably connected to the third sliding groove 311. The arrangement of the second slider 420 and the third slider 430 makes the second clamping plate 410 slide more smoothly.

[0043] In some embodiments, the first end of the third slide groove 311 is connected to the first slider 320, and the second end of the third slide groove 311 is provided with a second stop 312. The third slider 430 slides between the first slider 320 and the second stop 312. The second stop 312 is used to prevent the third slider 430 from disengaging from the third slide groove 311.

[0044] In some embodiments, the second stop 312 is integrally formed with the first clamping plate 310.

[0045] In some embodiments, the second adjusting assembly 40 includes a second elastic member 440 disposed within the third sliding groove 311 and located between the third slider 430 and the second stop member 312. When the power supply is clamped between the base plate 110 and the second clamping plate 410, the second elastic member 440 is in a compressed state, thereby causing the elastic force of the second elastic member 440 to drive the second clamping plate 310 to abut against the top of the power supply. The second elastic member 440 automatically adjusts the clamping force, reducing the risk of power supply deformation due to excessive clamping force.

[0046] In some embodiments, the second elastic member 440 is a spring. Specifically, a guide rod 313 is provided in the third slide groove 311. The first end of the guide rod 313 is connected to the first slider 320, and the second end of the guide rod 313 is connected to the second stop member 312. The third slider 430 is slidably sleeved on the guide rod 313, and the second elastic member 440 is sleeved on the guide rod 313. The guide rod 313 can guide the second elastic member 440 on the one hand, reducing the risk of tilting during the movement of the second elastic member 440, which is beneficial to improving the clamping effect of the second clamping plate 410. On the other hand, it can guide the third slider 430.

[0047] In some embodiments, the second adjustment assembly 40 includes a second locking member 450, which restricts the movement of the second slider 420 or the third slider 430 or the second clamping plate 410 when the second clamping plate 410 abuts against the top of the power source.

[0048] In some embodiments, one end of the second locking member 450 is fixed to the back plate 120, and the other end of the second locking member 450 is operable to clamp or release the second clamping plate 410. When the second clamping plate 410 abuts against the top of the power supply, the second locking member 450 clamps the second clamping plate 410 to restrict the movement of the second clamping plate 410, and when it is necessary to remove the power supply from the clamping device, the second locking member 450 releases the first clamping plate 310.

[0049] In this embodiment, the second locking member 450 is movably connected to the third slider 430. Specifically, the second locking member 450 is a locking bolt, threadedly connected to the third slider 430. When the second clamping plate 410 abuts against the top of the power supply, the second locking member 450 is tightened to abut against the guide rod 313 to restrict the movement of the third slider 430 and the second clamping plate 410. When it is necessary to remove the power supply from the clamping device, the second locking member 450 releases the guide rod 313, that is, the second locking member 450 is loosened to disengage from the guide rod 313. It can be understood that the third slider 430 has a threaded hole, and the second locking member 450 is threadedly connected to this threaded hole.

[0050] In practice, loosen the first locking member to release the moving rod, and simultaneously loosen the second locking member to release the guide rod. Then, manually push the first and second clamping plates to move them away from the first fixed plate. Place the power supply on the base and make the back of the power supply abut against the back plate. Then release the power supply, and the first and second clamping plates will automatically clamp the power supply under the elastic force of the first and second elastic members.

[0051] The clamping device provided in this application embodiment clamps the side of the power supply by cooperating with the first clamping plate and the first fixing plate. Additionally, the second clamping plate cooperates with the base to clamp the top and bottom of the power supply, achieving locking of the power supply from two directions and reducing the risk of power supply displacement.
