Description

Technical Field

[0001] This invention relates to the field of refrigeration chip testing technology, and in particular to a refrigeration chip performance testing device. Background Technology

[0002] To ensure that the cooling chip can work properly, its performance needs to be accurately tested. A cooling chip performance testing device is required when testing the cooling chip performance.

[0003] The testing device is equipped with a male connector that mates with the female connector on the cooling chip. However, most existing testing devices lack a protective mechanism to assist in positioning the male connector's connecting rod, thereby enhancing its support strength and preventing it from being bent or broken when the female connector is inserted into the male connector. This results in the male connector easily bending or breaking the connecting rod when the female connector is inserted into the male connector, reducing the lifespan of both the connecting rod and the male connector, increasing the frequency of male connector replacement, and indirectly increasing the operating cost of the testing device. Summary of the Invention

[0004] In view of this, the present invention provides a cooling chip performance testing device to solve the problem that existing testing devices lack a protective mechanism that can assist in positioning the power connector rod on the male connector, thereby enhancing the support strength of the power connector rod and preventing the power connector rod from being bent or broken when the female connector is plugged into the male connector.

[0005] The technical solution proposed in this invention is: a performance testing device for a cooling chip, specifically including an operating table, wherein multiple male power connectors are arranged and installed on the top of one side of the operating table; The power connector includes a base, an integrally formed vertical support block on the top of the base, and two power connector rods symmetrically inserted into the vertical support block. Two T-shaped guide rods are symmetrically fixed to both sides of the power connector at the top of the operating table. A horizontal positioning plate is slidably mounted on the two T-shaped guide rods by a spring-loaded mechanism. The two power connector rods slide through and slide with the horizontal positioning plate. Two hook-and-loop positioning components are symmetrically and rotatably mounted on the bottom of the horizontal positioning plate. Each hook-and-loop positioning component includes a main pull plate and a mounting plate located on the main pull plate. The main body of the pull plate has a rotating shaft at the top, a wedge-shaped hook block integrally formed on the bottom part of the main body pull plate, and a baffle fixed to one end of the rotating shaft. A tension spring is connected between the two main body pull plates of the two hook positioning components. The inner part of the baffle plate abuts against the horizontal positioning plate, and its main body protrudes from the horizontal positioning plate. Two positioning wedge blocks are symmetrically fixed on the vertical support block. When the two hook positioning components slide down with the horizontal positioning plate, the inclined surfaces of the two wedge-shaped hook blocks abut against the inclined surfaces of the two positioning wedge blocks.

[0006] Furthermore, the spring that pushes the horizontal positioning plate is fitted onto the T-shaped guide rod and compressed and clamped between the operating table and one end of the horizontal positioning plate.

[0007] Furthermore, four positioning bushings are symmetrically fixed to the bottom of the horizontal positioning plate, and the two positioning bushings at the two ends of the rotating shaft respectively pass through and rotate in cooperation.

[0008] Furthermore, the power connector also includes two symmetrically inserted power connector shafts in the base and the vertical support block. The top of the operating table is symmetrically provided with two power connector holes that are adapted to the shape of the power connector shafts at the position of the power connector. The two power connector shafts are connected and engaged with the two power connector holes. The base is fixedly connected to the operating table by bolts.

[0009] Furthermore, both of the main pull plates have protruding mounting rods fixedly connected to their bottom ends, and the two ends of the tension spring are respectively connected to the two protruding mounting rods.

[0010] Furthermore, an electrical box is installed on the top of the control panel away from the power connector. Two rows of indicator lights are embedded in the inclined side wall of the electrical box. The upper indicator light is used to warn of abnormal cooling chip, and the lower indicator light is used to indicate that the cooling chip is normal.

[0011] Furthermore, the top of the electrical box is used to support and place the refrigeration chip to be tested. The power connector of the refrigeration chip has two symmetrically arranged power connector holes inside, which are adapted to the shape of the power connector rods. The two power connector rods are correspondingly interference-fitted with the two power connector holes.

[0012] Furthermore, the electrical box is equipped with a test controller, which is electrically connected to the upper and lower rows of indicator lights, and the power socket is electrically connected to the test controller.

[0013] The present invention provides a performance testing device for a cooling chip, which has the following advantages: 1. The horizontal positioning plate can surround and limit the two power connection rods, keeping them in a vertically supported position and indirectly enhancing their bending resistance. The horizontal positioning plate acts as a protective mechanism for the two power connection rods. Compared to existing technologies lacking such a protective mechanism, this invention avoids the situation where, during the connection process (female plug sliding down and male plug assembling), the female plug can easily bend, deform, or break the power connection rod due to misalignment between the power socket and the power connection rod. This helps extend the service life of the power connection rods, reduces the frequency of replacing the entire male plug when the power connection rod is damaged, and lowers the operating cost of the testing device.

[0014] 2. When the female plug slides down to the low position, it completes the combination connection with the male plug and pushes the horizontal positioning plate against the top of the vertical support block. When the horizontal positioning plate and the vertical support block are in contact, the top plane of the two wedge-shaped hooks and the bottom plane of the two positioning wedges are in contact. In this way, when the top plane of the two wedge-shaped hooks and the bottom plane of the two positioning wedges are in contact, the horizontal positioning plate can be locked in the low position where it is in contact with the vertical support block, intercepting the counter-force of the compressed springs on the two T-shaped guide rods. This prevents the upward counter-force from being transmitted to the female plug through the horizontal positioning plate, thus offsetting and weakening the frictional fixing force generated when the two plug rods and the two plug holes are interference-fitted, reducing the firmness of the combination connection between the female plug and the male plug.

[0015] Third, because the two baffles abut against and are close to the horizontal positioning plate, the fingers holding the power connector plug and pulling it out are close to the two baffles. This allows the fingers holding the power connector plug to push down the protruding parts of the horizontal positioning plate on the two baffles without moving them much, thus releasing and unlocking the horizontal positioning plate. In this way, the power connector plug pulling out operation and the horizontal positioning plate releasing and unlocking operation can be carried out by one hand at a time, eliminating the trouble of having to use both hands to perform the above two operations step by step. The operation is convenient and efficient.

[0016] 4. After the horizontal positioning plate is released and unlocked, it will be pushed back by the compressed spring on the T-shaped guide rod and slid back to its original position. When the horizontal positioning plate is pushed back to its original position, it can assist in pushing the power connector that is being slid out and disassembled, thus offsetting part of the interference friction resistance between the two power connector rods and the two power connector holes, making the removal and disassembly of the power connector more effortless and convenient.

[0022] The following is an embodiment of the present invention, please refer to it. Figures 1 to 10 : This embodiment proposes a cooling chip performance testing device, including an operating table 2, with multiple power connectors 4 arranged on the top of one side of the operating table 2; The male plug 4 includes a base 401, an upright support block 402 integrally formed on the top of the base 401, and two power plugs 403 symmetrically inserted into the upright support block 402. Two T-shaped guide rods 101 are symmetrically fixed on both sides of the top of the operating table 2 at the male plug 4. A horizontal positioning plate 6 is slidably installed on the two T-shaped guide rods 101 in the form of spring push. The two power plugs 403 are slidably engaged with the horizontal positioning plate 6. Two hook positioning components 5 are symmetrically rotated and installed at the bottom of the horizontal positioning plate 6. The hook positioning component 5 includes a main pull plate 501, a rotating shaft 502 set on the top of the main pull plate 501, a wedge-shaped hook 504 integrally formed on the bottom part of the main pull plate 501, and a baffle 506 fixed to one end of the rotating shaft 502. A tension spring 505 is connected between the two main pull plates 501 of the two hook positioning components 5.

[0023] Preferably, the spring that pushes the horizontal positioning plate 6 is mounted on the T-shaped guide rod 101 and is compressed and clamped between the operating table 2 and one end of the horizontal positioning plate 6.

[0024] Preferably, four positioning bushings 601 are symmetrically fixed to the bottom of the horizontal positioning plate 6, and the two positioning bushings 601 at the two ends of the rotating shaft 502 respectively pass through and rotate in cooperation with each other.

[0025] Preferably, the male plug 4 also includes two symmetrically inserted electrical connectors 405 in the base 401 and the vertical support block 402. The top of the operating table 2 is symmetrically provided with two electrical connector holes 102 that are adapted to the shape of the electrical connectors 405 at the position of the male plug 4. The two electrical connectors 405 are connected to the two electrical connector holes 102 respectively. The base 401 is fixedly connected to the operating table 2 by bolts.

[0026] Preferably, the bottom ends of the two main pull plates 501 are fixedly connected to protruding mounting rods 503, and the two ends of the tension spring 505 are respectively connected to the two protruding mounting rods 503.

[0027] Preferably, an electrical box 1 is provided on the top of the control panel 2 away from the power connector 4. Two rows of indicator lights 201 are embedded in the inclined side wall of the electrical box 1. The upper indicator light 201 is used to warn of abnormality of the cooling chip 3, and the lower indicator light 201 is used to indicate that the cooling chip 3 is normal.

[0028] Preferably, the top of the electrical box 1 is used to support and place the cooling chip 3 to be tested. The internal part of the power connector 301 of the cooling chip 3 has two power connector holes 3011 that are symmetrically arranged to match the shape of the power connector rod 403.

[0029] Preferably, the electrical box 1 is equipped with a test controller, which is electrically connected to the upper and lower rows of indicator lights 201, and the power socket 102 is electrically connected to the test controller.

[0030] The following section provides a detailed explanation of the specific details, implementation steps, functions and interrelationships of the above features, and their roles in achieving this technical solution: The horizontal positioning plate 6 can surround and limit the two power connection rods 403, keeping them in a vertically supported position and indirectly enhancing their bending resistance. The horizontal positioning plate 6 acts as a protective mechanism for the two power connection rods 403. Compared to existing technologies lacking such a protective mechanism, the horizontal positioning plate 6 prevents the power connection rod 403 from being easily bent, deformed, or broken by the power connection female plug 301 during the process of sliding down and connecting with the power connection male plug 4. This helps extend the service life of the power connection rod 403, reduces the frequency of replacing the entire power connection male plug 4 when the power connection rod 403 is damaged, and helps lower the operating cost of the testing device.

[0031] When the female plug 301 slides down and connects with the male plug 4, the two connecting rods 403 and the two connecting holes 3011 are interference-fitted. The female plug 301 pushes and drives the horizontal positioning plate 6 to compress the springs on the two T-shaped guide rods 101 and move down along the two T-shaped guide rods 101 and the two connecting rods 403. When the horizontal positioning plate 6 is driven down along the two connecting rods 403, it can keep the two connecting rods 403 in place and protect them during the connection process, and leave space for the female plug 301 to slide down, so as to prevent the two connecting rods 403 from being bent or deformed during the above process. The frictional resistance generated when the female plug 301 and the male plug 4 are interference-fitted by the two connecting rods 403 and the two connecting holes 3011 is fixed in the combined connection state.

[0032] Under the pulling effect of the tension spring 505, the two main pull plates 501 move closer to each other and swing, and the two baffles 506 swing upward. During the upward swing of the two baffles 506, their inner parts abut against the horizontal positioning plate 6. When the two baffles 506 abut against the horizontal positioning plate 6, their main parts protrude out of the horizontal positioning plate 6.

[0033] As the two hook-and-positioning components 5 slide down with the horizontal positioning plate 6, the inclined surfaces of the two wedge-shaped hooks 504 on them abut against the inclined surfaces of the two positioning wedges 404. Through the guiding principle of the inclined surfaces of the two wedge-shaped hooks 504 and the two positioning wedges 404, when the horizontal positioning plate 6 slides down, it can push and drive the two main pull plates 501 and the two wedge-shaped hooks 504 to swing away from each other, creating space for the two wedge-shaped hooks 504 to pass through the two positioning wedges 404. When the two main pull plates 501 swing away from each other, the tension spring 505 is stretched. Subsequently, as the horizontal positioning plate 6 continues to slide down, when the two wedge-shaped hooks 504 pass through the two positioning wedges 404, the tension spring 505 is stretched. When wedge block 404 is in place, the two wedge-shaped hook blocks 504 and the two positioning wedge blocks 404 slide down and separate, and the tension spring 505 loses the pushing and holding force from the two positioning wedge blocks 404. It automatically pulls and drives the two main pull plates 501 to move closer to each other, rotate and reset. After the two main pull plates 501 are reset, the two wedge-shaped hook blocks 504 are placed on the bottom side of the two wedge-shaped hook blocks 504. At this time, under the reverse push of the spring on the two T-shaped guide rods 101, the horizontal positioning plate 6 slides upward and drives the two wedge-shaped hook blocks 504 to slide upward synchronously. When the two wedge-shaped hook blocks 504 are pushed upward, their top plane abuts against the bottom plane of the two positioning wedge blocks 404.

[0034] When the female plug 301 slides down to the low position, it completes the combination connection with the male plug 4, and pushes the horizontal positioning plate 6 against the top of the vertical support block 402. When the horizontal positioning plate 6 and the vertical support block 402 are in contact, the top plane of the two wedge-shaped hooks 504 and the bottom plane of the two positioning wedges 404 are in contact. In this way, when the top plane of the two wedge-shaped hooks 504 and the bottom plane of the two positioning wedges 404 are in contact, the horizontal positioning plate 6 can be locked and kept in the low position in contact with the vertical support block 402, intercepting the counter-pushing force of the compressed springs on the two T-shaped guide rods 101, and preventing the upward counter-pushing force from being transmitted to the female plug 301 through the horizontal positioning plate 6. This counteracts and weakens the frictional fixing force generated when the two power plugs 403 and the two power sockets 3011 are interference-fitted, reducing the firmness of the combination connection between the female plug 301 and the male plug 4.

[0035] When the female connector 301 and male connector 4 are connected, the cooling chip 3 can be tested. After the test is completed, the female connector 301 and male connector 4 need to be removed, and the tested cooling chip 3 can be unloaded from the top of the operating table 2. Pushing down the two baffles 506 can drive the two main pull plates 501 to swing away from each other, controlling the separation of the two wedge-shaped hooks 504 and the two positioning wedges 404, and releasing and unlocking the horizontal positioning plate 6. Since the two baffles 506 abut against and approach the horizontal positioning plate 6, they can then grip the female connector 301. When the fingers used to pull out the female connector 301 are close to the two baffles 506, they can simultaneously push down the protruding horizontal positioning plates 6 on the two baffles 506 without significant movement, thus releasing and unlocking the horizontal positioning plates 6. In this way, the pulling out of the female connector 301 and the releasing and unlocking of the horizontal positioning plates 6 can be carried out by one hand at a time, eliminating the trouble of having to use both hands to perform the two operations step by step, making the operation convenient and efficient.

[0036] After the horizontal positioning plate 6 is released and unlocked, it will be pushed back by the compressed spring on the T-shaped guide rod 101 and slid upward to reset. When the horizontal positioning plate 6 is pushed back and slid upward to reset, it can assist in pushing the power connector 301 that is being slid out and disassembled, thereby offsetting part of the interference friction resistance between the two power connector rods 403 and the two power connector holes 3011, making the removal and disassembly of the power connector 301 easier and more convenient.

[0037] The working principle of this embodiment is as follows: When the two connecting pins 405 are plugged into the connecting socket 102, the male connector 4 can be connected to the test controller for conduction. When the female connector 301 is connected to the male connector 4, the cooling chip 3 can be connected to the male connector 4 for conduction. Thus, when the female connector 301 is connected to the male connector 4, the cooling chip 3 can be indirectly connected to the test controller for conduction. During testing, the cooling chip 3 to be tested is placed on top of the operating table 2, and the female power connector 301 and the male power connector 4 are connected to make the cooling chip 3 electrically connected to the test controller. After the cooling chip 3 is electrically connected to the test controller, the test controller outputs current to power the cooling chip 3 and starts the cooling chip 3. After the cooling chip 3 is powered on and started, it begins to run and cool. During this process, the test controller monitors the operating current of the cooling chip 3 in real time and compares the actual operating current with the standard operating current in real time. If the actual real-time fluctuating operating current is less than the standard operating current within the specified operating time range, the actual performance of the cooling chip 3 is judged to be qualified; otherwise, the actual performance of the cooling chip 3 is judged to be unqualified.

[0038] When the cooling chip 3 is deemed unqualified, the test controller is powered on and the corresponding indicator light 201 on the upper side illuminates, indicating that the cooling chip 3 is malfunctioning. When the cooling chip 3 is deemed qualified, the test controller is powered on and the corresponding indicator light 201 on the lower side illuminates, indicating that the cooling chip 3 is functioning normally.
