Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0034] As competition in technological innovation becomes fierce, the TV industry is launching more and more new products. In new products of different sizes, the board sizes and shapes are usually different. In order to prevent problems in board design, it is necessary to use tooling to fix the board and conduct testing.

[0035] In the related art, the tooling is usually designed according to the size of the board, but the size of the board is updated quickly and the tooling is not universal, resulting in high tooling costs and a long production cycle for the tooling, which affects the test efficiency.

[0036] The utility model provides a board test tool, aiming to at least solve the problem in the related art that the tool is not universal, resulting in high tool cost and a long tool production cycle, which affects the test efficiency.

[0037] Please refer to Figure 1 and Figure 2 The board test fixture 100 includes a base 1 and a first fixed structure 2, the first fixed structure 2 includes two first slide rails 21 arranged on the base 6 at intervals along a first direction, the first slide rails 21 extend along a second direction, each of the first slide rails 21 is provided with two sliders 22, a first clamping space is defined between the four sliders 22, the first clamping space is used for placing the board to be tested to clamp the board to be tested, at least one of the first slide rails 21 can be slidably arranged along the first direction relative to another first slide rail 21, and the slider 22 can slide along the corresponding first slide rail 21 to adjust the first clamping space, the first direction and the second direction intersect.

[0038] In the technical solution of the utility model, the first fixing structure 2 includes two first slide rails 21 arranged on the base 6 at intervals along the first direction, the first slide rails 21 extend along the second direction, each of the first slide rails 21 is provided with two sliders 22, and a first clamping space is defined between the four sliders 22, the first clamping space is used for placing the board to be tested to clamp the board to be tested, at least one of the first slide rails 21 can be slidably arranged along the first direction relative to another first slide rail 21, and the slider 22 can slide along the corresponding first slide rail 21; in this way, the four sliders 22 form a first clamping space. The first clamping space can clamp and fix the board to be tested, the slider 22 can slide on the corresponding first slide rail 21 to adjust the size of the first clamping space in the second direction, and at least one of the first slide rails 21 can slide relative to the other in the first direction to change the distance between the two first slide rails 21 in the first direction, thereby changing the distance between the sliders 22 on two different first slide rails 21 in the first direction, thereby changing the size of the first clamping space in the first direction. In this way, the size of the first clamping space is adjustable, and boards to be tested of different sizes can be clamped and fixed.

[0039] Since the four sliders 22 can all slide, when the board to be tested is of a regular shape, the position of the slider 22 can be directly adjusted to well fix the board to be tested. When the board to be tested is of a regular shape, since the distance between the two first slide rails 21 can be changed, the position of the first slide rails 21 can be adjusted so that the corresponding slider 22 can clamp the board to be tested at a suitable position, and the adaptability range is wide.

[0040] After the slider 22 moves, it is necessary to keep the slider 22 stable to maintain the stability of the fixation of the board under test. There are various ways to keep the slider 22 stable. For example, the stability can be maintained by the frictional force between the slider 22 and the first slide rail 21, that is, the cooperation between the slider 22 and the first slide rail 21 is relatively tight, so that the slider 22 is difficult to move by itself without manual driving. For example, the slider 22 can also be submitted by tightening the screw. There are various ways, and you can choose according to actual needs.

[0041] This design does not limit the sliding fit mode between the slider 22 and the first slide rail 21. For example, the slider 22 can be directly slidably installed in a chute, that is, the cooperation mode of the sliding convex and the sliding concave, or the cooperation mode of the slide bar and the hole provided on the slider 22 can be adopted.

[0042] For the two first slide rails 21, both can slide, or one of them can slide. In the embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the first fixing structure 2 further includes at least one second slide rail 23 extending along the first direction, and one end of each of the two first slide rails 21 is slidably installed on the second slide rail 23; thus arranged, both of the two first slide rails 21 can slide. When facing the irregular board under test, the four sliders 22 can all slide along the first direction, so as to conveniently find a suitable clamping position.

[0043] Among them, the second slide rail 23 can be set to one, or can be set to two or more. Please refer to Figure 2 , in this embodiment, the second slide rail 23 is set to two, and both ends of the first slide rail 21 are slidably connected to the two second slide rails 23 respectively.

[0044] Of course, the first slide rail 21 also needs to maintain its stability after sliding. Similarly, the first slide rail 21 can maintain its stability by the frictional force with the second slide rail 23, or a tightening screw can be provided to fix it.

[0045] The usage environment of the board is usually within a housing structure. In order to enable the board test work to better simulate the actual working environment to conduct some power-on or temperature-rising tests on the board, in some embodiments, please refer to Figure 1 and Figure 3, the board test fixture 100 also includes a frame structure 3 arranged on the base plate 1, the frame structure 3 and the base plate 1 are enclosed to form an accommodating cavity with an opening arranged opposite to the base plate 1; the first fixed structure 2 is located in the accommodating cavity; the board test fixture 100 also includes a cover plate 4 arranged on the frame structure 3, and the cover plate 4 can cover the opening of the accommodating cavity. In this way, by setting the cover plate 4 and the frame structure 3, and the base plate 1 to form a relatively closed accommodating cavity, the actual use environment is simulated to improve the accuracy of the test. Even if the actual working environment of some boards is relatively exposed, it can be simulated by opening the cover plate 4.

[0046] In order to be able to see the state of the internal board from the outside when the cover plate 4 covers the accommodating cavity, in some embodiments, at least part of the cover plate 4 is made of transparent material for easy observation. The cover plate 4 can be partially or entirely made of transparent material. The design does not limit the type of transparent material, and can be acrylic or glass. Since the board is usually subject to a temperature rise test, the transparent material is preferably a high temperature resistant material.

[0047] It can be understood that the slider 22 and the first slide rail 21 have certain sizes. When the size of the base plate 1 is certain, even if the slider 22 and the first slide rail 21 slide to the outermost edge of the base plate 1, there is still a certain space on the base plate 1. In particular, when testing irregular boards and cards, there may be no suitable clamping position; in order to further improve the adaptation range, in some embodiments, the frame structure 3 includes two side panels 31 arranged opposite to each other in a first direction; the board and card testing fixture 100 also includes a second fixed structure 5, and the second fixed structure 5 includes two third slide rails 51 respectively arranged on the opposite side of the two side panels 31, and two clamping blocks 52 are slidably arranged on each of the third slide rails 51, and a second clamping space is defined between the four clamping blocks 52, and the second clamping space is used for placing the board and card to be tested so as to clamp the board and card to be tested. In this way, by arranging a total of four clamping blocks 52 on the two side panels 31, the board to be tested can be clamped and fixed by the four clamping blocks 52. For boards with irregular shapes, when it is difficult for the slider 22 to find a suitable clamping position within the maximum range of the first clamping space, the board can be clamped and fixed by the four clamping blocks 52. For boards with regular shapes, even if they can be fixed by the four sliders 22, they can be further fixed by the four clamping blocks 52, thereby fully utilizing the space in the accommodating cavity.

[0048] The size of the clamp block 52 is limited, so when the board is fixed by the clamp block 52, the size of the board that can be adapted is also limited. In order to increase the size of the second clamping space, in some embodiments, at least one of the side panels 31 can be slid along the first direction relative to the other side panel 31; with this arrangement, the distance between the clamp blocks 52 on both sides is adjustable, so that smaller boards can be adapted. At the same time, by adjusting the spacing between the two side panels 31, the two side panels 31 can also clamp and fix the board, thereby improving the fixing effect.

[0049] One of the two side panels 31 can slide, or both can slide. In some embodiments, the first fixing structure 2 further includes at least one second slide rail 23 extending along the first direction; one end of the two side panels 31 is slidably mounted on the second slide rail 23. In this way, the two side panels 31 can slide through the second slide rail 23. After the board is fixed by the four sliders 22, it is more convenient to clamp it by the side panels 31. At the same time, the sliding of the side panels 31 is realized by the second slide rail 23, and there is no need to set a slide rail for the side panels 31 separately, which can save space and cost.

[0050] In order to power on the board in the cavity, please refer to Figure 3 The frame structure 3 is also provided with a wiring hole 311 connected to the accommodating cavity. In the present embodiment, the wiring hole 311 is provided on the side plate 31. Of course, the position of the wiring hole 311 is not limited thereto, and may also be provided at other places of the frame structure 3.

[0051] Please refer to Figure 1 and Figure 3 The frame structure 3 includes a first baffle 32 and a second baffle 33 arranged opposite to each other in the second direction. The first baffle 32, the second baffle 33 and the two side panels 31 are combined with the bottom plate 1 to form the accommodating cavity. The end of the bottom plate 1 where the second baffle 33 is provided is provided with a base 6. In this way, the base 6 can be used to make the entire board test fixture 100 stand up better to simulate the actual usage environment of the board.

[0052] When actually in use, the board is usually located in a shell structure, and this shell structure usually has heat dissipation holes 321 for heat dissipation. In order to improve the authenticity of the temperature rise test, the first baffle 32 is also provided with a plurality of heat dissipation holes 321 connected to the accommodating cavity, thereby reducing the possibility that the accommodating cavity is too closed, resulting in a large error between the test result and the actual use result.

[0053] It is understandable that when the board is fixed by the four blocks, the contact area between the board and the card is small, especially when the board is tested vertically, if the contact area is too small, there may be a problem of pressure concentration and damage. Therefore, in some embodiments, the first baffle 32 is fixedly connected to the bottom plate 1, and the second baffle 33 can be slidably arranged along the second direction relative to the bottom plate 1; in this way, the board can be supported by the sliding of the second baffle 33. The fixing of the second baffle 33 after sliding can also be done by friction or locking screws.

[0054] In order to enable the second baffle 33 to slide along the second direction, in some embodiments, both ends of the second baffle 33 are slidably mounted on the two third slide rails 51, and the second baffle 33 slides through the third slide rails 51, without the need for an additional slide rail structure, thereby saving cost and space.

[0055] Since the two side panels 31 need to slide in the first direction, and the second baffle plate 33 located between the two side panels 31 needs to slide in the second direction, there will be interference in the sliding of the side panels 31 and the second baffle plate 33. Therefore, in the present embodiment, the second baffle plate 33 includes two main body portions 331 which are separately arranged, and the ends of the two main body portions 331 which are away from each other are respectively slidably installed on the two third slide rails 51, and the two main body portions 331 can be slidably arranged in the first direction relative to each other; with such arrangement, when the two side panels 31 slide, the two main body portions 331 of the second baffle plate 33 will also slide along, and there will be no motion interference, and the two main body portions 331 can still slide in the second direction along the third slide rail 51.

[0056] There are many ways for the two main bodies 331 to slide along the first direction. In some embodiments, one of the main bodies 331 can be mounted on the outside of the other main body 331. In some embodiments, the two main bodies 331 are staggered in the second direction and partially overlap.

[0057] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
