[0002] With the rapid development of the semiconductor industry, the design, packaging and testing of electronic components have broad application prospects. Especially in the field of chip testing, test equipment is particularly important as an indispensable testing fixture for chip testing.

[0003] With the improvement of semiconductor test equipment performance and its integrated system application, power supply devices that provide high-stability performance for test equipment have become key components. In existing power supply devices, the power module and backplane are installed in a vertical plug-in manner, which not only takes up a large space and is not convenient for expansion, but also the installed power board and power backplane can only be taken out separately. If they need to be taken out at the same time, a lot of disassembly and assembly work must be done, which makes the installation operation inconvenient. In addition, since the power board and power backplane can only be installed inside the chassis, it is difficult to check the connectors of the power board and power backplane with the naked eye. Therefore, it is easy for cables, devices and other objects to interfere with the installation of the power board and power backplane, thereby affecting the signal transmission of the power supply device. Summary of the invention

[0004] The invention provides a test power supply device and a test chassis to solve the problems in the prior art that the power supply device is inconvenient to install and operate, occupies a large space and is inconvenient to expand.

[0015] Preferably, an extension rod is provided at the end of the guide plate, and a pull rod is provided at the end of the extension rod.

[0016] Preferably, guide sleeves are respectively provided at both ends of the support plate so as to position and install the power supply body in the box body of the detection chassis.

[0017] Preferably, the power supply assembly comprises: a power supply module, a power supply board and a heat dissipation module for dissipating heat for the power supply module and the power supply backplane, wherein the power supply module communicates with the power supply backplane via the power supply board.

[0018] Preferably, the heat dissipation module includes: a heat conducting plate located between the power module and the power backplane and attached to the surface of the power backplane, a heat conducting pipe having one end connected to the heat conducting plate to conduct heat, a radiator installed on the support plate and connected to the other end of the heat conducting pipe, and a cooling fan, wherein the cooling fan is arranged on one side of the radiator to dissipate the heat of the radiator.

[0019] Preferably, a limiting component is further included, and after the power supply body is installed, the limiting component limits the two ends of the power supply body respectively.

[0020] The invention also provides a test chassis, comprising a test power supply device.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The mounting bracket of the present invention is provided with at least two sets of mounting plates, which can provide sufficient mounting space according to the number of power supply bodies.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0050] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] The present invention provides a test power supply device, which is used to provide power to a test device and can be expanded according to the requirements of the test device. Figure 1 and Figure 2 As shown, the test power supply device includes: a power supply body 1, a mounting bracket 2 and a pull-out mechanism 3. The power supply body 1 is provided with at least one group, and the pull-out mechanism 3 is respectively located on both sides of the power supply body 1 to slide the power supply body 1 and the mounting bracket 2 together. Of course, in order to adapt to different numbers of power supply bodies 1, the mounting bracket 2 and the pull-out mechanism 3 can be expanded as needed to provide sufficient installation space for the power supply body 1.

[0052] Please refer to Figure 1 and Figure 2 The mounting bracket 2 includes: at least two sets of mounting plates 21 arranged in parallel with each other, two adjacent sets of mounting plates 21 together constitute an installation space, and each installation space corresponds to accommodating a set of the power source body 1. Figure 1 As shown, four groups of the mounting plates 21 can be installed correspondingly to three groups of the power supply bodies 1, and the structure is extremely delicate and easy to disassemble and assemble. Furthermore, the mounting bracket 2 also includes a connecting rod 22 for fixing and supporting the mounting plate 21. The connecting rod 22 is usually located at the bottom of the mounting plate 21 and will not affect the installation of other mechanisms. When the installation space needs to be expanded or reduced, it is only necessary to extend or shorten the connecting rod 22, and install the mounting plate 21 on the connecting rod 22 or remove the mounting plate 21 from the connecting rod 22.

[0053] Key References Figure 2 and Figure 3The pulling mechanism 3 includes: a connecting plate 31 and a guide plate 32. The connecting plate 31 is used to connect with the power supply body 1 to guide the power supply body 1 into the installation space, and the guide plate 32 is arranged between the installation plate 21 and the connecting plate 31 to provide guidance for the connecting plate 31 and guide the connecting plate 31 and the power supply body thereon to descend to the set installation position, so as to facilitate the connection of the power supply body 1 with other devices.

[0054] Continue to refer to 2 and Figure 3 , a first waist-shaped hole 321 is horizontally provided on the guide plate 32. A guide groove 211 is provided on the mounting plate 21, and a first roller 212 is provided in the guide groove for moving along the first waist-shaped hole 321. The guide plate 32 is installed in the guide groove 211 and can slide back and forth in the guide groove 211. The size of the guide groove 211 is determined according to the size and movement range of the guide plate 32, so as to provide sufficient installation and sliding space for the guide plate 32.

[0055] Preferably, the guide plate 32 is further provided with a second waist-shaped hole 322 which is arranged obliquely, and the connecting plate 31 is provided with a second roller 311 which moves along the second waist-shaped hole 322, so that the connecting plate 31 tilts relative to the guide plate 32. Furthermore, the mounting plate 21 is provided with a vertical slide rail 213, and the connecting plate 31 is provided with a vertical slider 312 which matches the vertical slide rail 213. Therefore, the connecting plate 31 has a vertical degree of freedom, and when the connecting plate 31 is subjected to force, it will descend along with the vertical slide rail 213 until the bottom of the connecting plate 31 contacts the connecting rod 22.

[0056] Furthermore, an extension rod 33 is provided at the end of the guide plate 32, and a pull rod 34 is provided at the end of the extension rod 33. The pull rod 34 can pull the guide plate 32 to move in the guide groove 211, thereby driving the connecting plate 31 to rise or fall.

[0057] Key References Figures 4 to 7, the power supply body 1 includes: a support plate 11, a power back plate 12 and a power assembly 13. Among them, the support plate 11 is used to provide installation space for the power back plate 12 and the power assembly 13, and the support plate 11 also cooperates with the pull-out mechanism 3 to be smoothly installed on the mounting bracket 2. The power back plate 12 is a flat plate structure with a relatively large area, so it is directly laid on the side of the support plate 11. Of course, there are several components on the power back plate 12, so there are several openings on the support plate 11 to make way for each component. The power assembly 13 is distributed and installed on the other side of the support plate 11 and is reasonably laid out and accurately arranged. Therefore, in this embodiment, the force points of the installation of the power assembly 13 and the power back plate 12 are concentrated on the support plate 11, not on the power back plate 12, so the power back plate 12 will not be affected, ensuring the stability of the output signal.

[0058] Specific as Figure 4 As shown, both sides of the support plate 11 are provided with slide grooves 111 corresponding to the connecting plate 31. When installing the power supply body 1, just align the top edge of the connecting plate 31 with the slide groove 111 of the support plate 11, and then push the support plate 11 until the connecting plate 31 contacts the end of the slide groove 111, and the first step of installing the power supply body 1 is completed. The operation is convenient and easy to use.

[0059] Reference Figure 5 , guide sleeves 15 are respectively provided at both ends of the support plate 11. The guide sleeves 15 are provided with guide posts or guide holes, through which the support plate 11 can be aligned with the housing of the detection chassis, so that the support plate 11 and the power backplane 12 and power assembly 13 thereon are precisely positioned and installed inside the housing, ensuring the plug-in accuracy of the power backplane 12, and avoiding damage to the docking plug-in and signal influence caused by plug-in accuracy problems.

[0060] like Figures 5 to 7 As shown, the power supply assembly 13 includes: a power supply module 131, a power board 132 and a heat dissipation module 133 for dissipating heat for the power supply module 131 and the power supply backplane 12, wherein the power supply module 131 communicates with the power supply backplane 12 through the power board 132, wherein the power board 132 and the power supply module 131 communicate directly through a connector, and the power board 132 and the power supply backplane 12 communicate through a connecting line with a connector. Therefore, the power supply backplane 12 and the power supply assembly 13 in this embodiment are connected to each other after the installation and fixation are completed, instead of plugging the power board 132 or the power supply module 131 into the power supply backplane 12, so as to avoid losses to the power supply backplane 12.

[0061] Reference Figure 6 to Figure 7, the heat dissipation module 133 includes: at least one group of heat conducting plates 1331, multiple groups of heat conducting pipes 1332 and a radiator 1333. The heat conducting plates 1331 fit tightly against the surface of the power supply backplane 12, and can quickly absorb the heat on the surface of the power supply backplane 12. One end of the heat conducting pipe 1332 is connected to the heat conducting plate 1331, and the other end extends outward and is connected to the radiator 1333, so as to transfer the heat on the heat conducting plate 1331 to the radiator 1333, and avoid heat accumulation on the power supply backplane 12. In order to improve the heat dissipation effect, the radiator 1333 is usually set at a relatively large space. In this embodiment, the radiator 1333 is set at the end of the power supply module 131, and dissipates heat outward to avoid the dissipated heat affecting the power supply module 131.

[0062] Continue to refer to Figure 6 and Figure 7 A cooling fan 1334 is also provided on one side of the radiator 1333. The cooling fan 1334 blows air to the radiator 1333 to accelerate the diffusion of the heat on the radiator 1333. Since the radiator 1333 is located at the end of the power module 131, the cooling fan 1334 can be arranged on the side where the radiator 1333 is connected to the heat pipe 1332 and is also the side of the radiator 1333 close to the power module 131. In this way, the cooling fan 1334 can blow air to the radiator 1333 and part of the heat pipe 1332 to dissipate heat at the same time, and at the same time, the blown cooling air passes through the heat pipe 1332 and the radiator 1333 and diffuses to the outside of the power module 131, ensuring that the dissipated heat will not affect the power module 131.

[0063] Preferably, the support plate 11 is further provided with an outer cover 14, which cooperates with the support plate 11 to form a box-shaped housing that can accommodate the power supply assembly 13, protect the power supply assembly 13, and facilitate the overall installation and movement of the power supply body 1. The outer cover 14 is provided with heat dissipation holes, which are usually located at both ends and the top surface (or bottom surface) of the outer cover 14, so that the heat inside the power supply body 1 can be promptly diffused to the external air through the heat dissipation holes.

[0064] After the above-mentioned test power supply device of this embodiment is installed, the power supply body 1 may be displaced or even fall off due to external forces during the later transportation or movement. Therefore, the test power supply device also includes a limit component 4. After the power supply body 1 is installed, the limit component 4 limits the two ends of the power supply body 1 respectively. Figure 2 and Figure 5 As shown, there are two groups of limit components 4, which are respectively arranged at the two ends of the power supply body 1. One group of limit components 4 is arranged at the end of the mounting plate 21, such as Figure 2As shown, it is used to limit the extension rod 33 of the guide plate 32, and another set of limiting components 4 is at the end of the support plate 11, such as Figure 5 As shown, it is used to limit the support plate 11. Specifically, the two groups of limiting components 4 each include a limiting block 41 and a limiting roller 42, the limiting roller 42 is fixed on the mounting plate 21 or the support plate 11, and the limiting block 41 is provided with a waist-shaped hole matching the limiting roller 42, and the limiting block 41 slides relative to the limiting roller 42, and then extends out to press against the end of the extension rod 33 of the guide plate 32 or against the end of the mounting plate 21, so that the power supply body 1 is fixed relative to the mounting plate 21 and the guide plate 32, effectively ensuring the stability of the power supply body 1 during movement.
