Description

Technical Field

[0001] The utility model relates to the field of testing devices, and more particularly to a double-floating heat dissipation testing device. Background Art

[0002] A heat dissipation testing device is a device used to test the heat dissipation performance of a chip or other electronic components. Its principle is to place the chip or other electronics on a test seat, then use a radiator to press on top of the chip, and then power on the chip to test its heat dissipation performance.

[0003] To ensure the accuracy of the test, it is necessary to ensure that the pressing between the radiator and the chip is in place without gaps. The traditional solution usually uses a knob type, that is, by setting a knob on the top, using the knob to screw the housing with the radiator onto the housing with the chip, so as to press the radiator on the chip. However, the knob type has the following defects. First, the knob type structure must be paired with threads. As the number of tests increases, the threads are prone to aging, resulting in the failure of the knob type mechanism. Second, the pressure of the knob type is basically concentrated in the middle of the housing, and it is easy to cause the surrounding to warp during the screwing process, resulting in flaws in the pressing between the radiator and the chip. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides a double-floating heat dissipation testing device, which includes a first housing and a second housing that can be covered together up and down. A test seat is arranged in the second housing, and a heat dissipation pressing block is arranged in the first housing. The heat dissipation pressing block can move up and down in the first housing. Floating plates are suspended on opposite sides of the first housing, and the floating plates are connected to the heat dissipation pressing block. Knobs with opposite positions are arranged on both sides of the first housing, and cam portions are arranged on the circumferential surfaces of the knobs.

[0005] Furthermore, a first rotating shaft is arranged on the side surface of the first housing. The knob is installed on the first rotating shaft and rotates around the first rotating shaft.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in this specification in the description of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.

[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] Now, further description will be made on the preferred embodiments of the present utility model in conjunction with the accompanying drawings. Figures 1 to 6As shown in the figure, a double-floating heat dissipation test device includes a first housing 100 and a second housing 200 that can be covered together up and down. A test seat 210 for placing a product 10 to be tested is arranged in the second housing 200. A heat dissipation pressing block 300 is arranged in the first housing 100, and the heat dissipation pressing block 300 can move up and down in the first housing 100. Floating plates 400 are suspended on opposite sides of the first housing 100, and the floating plates 400 are connected to the heat dissipation pressing block 300. Knobs 500 are arranged on both sides of the first housing 100, and the positions of the knobs 500 are directly opposite on both sides of the first housing 100. A cam portion 510 is arranged on the circumferential surface of the knob 500. When the product 10 to be tested is placed on the test seat 210, the first housing 100 and the second housing 200 are covered together up and down. When the knob 500 is rotated until the cam portion 510 contacts the floating plate 400, the knob 500 controls the floating plate 400 to press down. Since the floating plate 400 is connected to the heat dissipation pressing block 300, the floating plate 400 will drive the entire heat dissipation pressing block 300 to press down and thus contact the product 10 to be tested, facilitating subsequent heat dissipation tests. Compared with the prior art, in this application, floating plates 400 connected to the heat dissipation pressing block 300 are suspended on opposite sides of the first housing 100, and then the rotation of the knob 500 is used to control the floating plate 400 to drive the entire heat dissipation pressing block 300 to press down and contact the product 10 to be tested. While ensuring that the heat dissipation pressing block 300 can fully contact the product 10 to be tested, the overall structure is simple and the operation is convenient.

[0032] Furthermore, on the basis of the above embodiment, a first rotating shaft 110 is arranged on the side surface of the first housing 100. The knob 500 is installed on the first rotating shaft 110 and rotates around the first rotating shaft 110. A guiding shaft 111 is also arranged on the side surface of the first housing 100. A U-shaped guiding groove 520 is formed on the knob 500. When the first housing 100 and the second housing 200 are covered together up and down and the knob 500 is rotated until the cam portion 510 contacts the floating plate 400, the guiding shaft 111 moves relatively in the guiding groove 520. In this way, when the knob 500 rotates, the cam portion 510 can better contact the floating plate 400, enabling it to complete the pressing down of the floating plate 400 only by rotating a very short angle. The operation is more convenient and the rotation angle can be adjusted at any time according to the thickness of different products 10 to be tested, and it can be applied to different products 10 to be tested.

[0033] The heat dissipation pressing block 300 includes a first pressing block 301 and a second pressing block 302, and the second pressing block 302 is embedded in the first pressing block 301. In this way, different heat dissipation pressing blocks 300 can be adjusted for different thicknesses and different types of products 10 to be measured. For example, when encountering a product 10 to be measured with a relatively thin or fragile thickness, only the first pressing block 301 needs to be used. When encountering a product 10 to be measured with a relatively thick or high strength, the second pressing block 302 can be embedded in the first pressing block 301, so as to maintain sufficient pressing force on the product 10 to be measured.

[0034] Furthermore, on the basis of the above embodiment, two first stroke rods 120 are respectively arranged on both sides of the first housing 100. One end of the first stroke rod 120 is movably connected to the first housing 100, and the other end of the first stroke rod 120 is fixedly connected to the floating plate 400. Therefore, a suspension connection is formed between the floating plate 400 and the first housing 100. When the first housing 100 and the second housing 200 are covered up and down, the floating plate 400 will rise and push up the first stroke rod 120. When the rotary knob 500 is rotated to control the floating plate 400, the floating plate 400 can be pressed down along the first stroke rod 120.

[0035] Furthermore, on the basis of the above embodiment, two second stroke rods 310 are respectively arranged on both sides of the heat dissipation pressing block 300. One end of the second stroke rod 310 is movably connected to the heat dissipation pressing block 300, and the other end of the second stroke rod 310 is fixedly connected to the floating plate 400. Therefore, a suspension connection is also formed between the floating plate 400 and the heat dissipation pressing block 300. When the first housing 100 and the second housing 200 are covered up and down, the heat dissipation pressing block 300 will rise and push up the first stroke rod 120. When the rotary knob 500 is rotated to control the floating plate 400, the floating plate 400 can drive the heat dissipation pressing block 300 to be pressed down along the second stroke rod 310.

[0036] Furthermore, on the basis of the above embodiment, a spring 320 is arranged between the heat dissipation pressing block 300 and the floating plate 400. When the first housing 100 and the second housing 200 are not covered, the spring 320 separates the heat dissipation pressing block 300 and the floating plate 400, and the two are only connected by the second stroke rod 310. When the first housing 100 and the second housing 200 are covered up and down, the spring 320 is compressed, and it remains compressed during the process that the floating plate 400 drives the heat dissipation pressing block 300 to be pressed down along the second stroke rod 310. When the heat dissipation pressing block 300 is pressed down as a whole to contact the product 10 to be measured, the spring 320 can provide additional elastic force, so as to ensure better pressing force of the heat dissipation pressing block 300.

[0037] Furthermore, based on the above embodiments, a second rotating shaft 220 is provided on the second housing 200. The first housing 100 and the second housing 200 are rotatably connected through the second rotating shaft 220. A chip positioning seat 230 is provided around the test seat 210. The chip positioning seat 230 is used to help the chip be placed more precisely on the test seat 210 for positioning with the test probe. Preferably, a positioning rod 240 is provided upward on the second housing 200, and a positioning hole 231 that cooperates with the positioning rod 240 is provided on the chip positioning seat 230. When the chip positioning seat 230 is installed on the second housing 200, inserting the positioning rod 240 into the positioning hole 231 can better ensure that the chip positioning seat 230 is installed in place.

[0038] Furthermore, based on the above embodiments, a third rotating shaft 130 is still provided on the first housing 100. A claw 140 is rotatably installed on the third rotating shaft 130. A fixing rod 250 that cooperates with the claw 140 is provided on the second housing 200. When the rotary knob 500 is rotated to control the floating plate 400 to press down, driving the overall pressing down of the heat dissipation pressing block 300 to contact the product to be tested 10, then the claw 140 is rotated and buckled on the fixing rod 250, so as to maintain the contact state between the heat dissipation pressing block 300 and the product to be tested 10.

[0039] Details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
