Description

Technical Field

[0001] The utility model belongs to the technical field of integrated circuit testers, and in particular relates to an integrated circuit tester which is easy to repair. Background Art

[0002] An integrated circuit is a miniature electronic device that uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit, and is made on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit function. Integrated circuits have the advantages of small size, light weight, fewer lead wires and welding points, long life, high reliability, good performance, etc., and at the same time, low cost and easy mass production. Integrated circuit testers are special instruments and equipment for testing integrated circuits. Integrated circuit testing is one of the key means to ensure the performance and quality of integrated circuits. Integrated circuit testing technology is one of the three major supporting technologies for the development of the integrated circuit industry.

[0003] However, there are some problems with the prior art: the casing of the prior integrated circuit tester is usually connected with screws. When the circuit board inside the integrated circuit tester is damaged, it is necessary to first remove the casing of the integrated circuit tester to display the internal circuit board, and then remove the screws connecting the circuit board before the circuit board can be taken out from the inside of the integrated circuit tester casing. The disassembly process is relatively cumbersome, and the screws may rust and become unable to be removed, resulting in the circuit board being unable to be repaired, which can easily affect the use of the integrated circuit tester. Therefore, we propose an integrated circuit tester that is easy to repair. Utility Model Content

By separating the plug-in block from the plug-in slot, the connection relationship between the cover plate and the tester housing is changed, thereby facilitating the sliding cover plate to open the inspection port and perform maintenance work on the interior. The fixing component is then removed from one end of the support table, thereby releasing the restriction of the fixing component on the circuit board, making it convenient to remove the circuit board from the upper surface of the placement plate, thereby improving the disassembly speed of the circuit board, facilitating the maintenance work on the circuit board, and further improving the maintenance speed of the integrated circuit tester.

[0005] The utility model is implemented as follows: an integrated circuit tester that is easy to maintain, includes a tester shell, an inspection port is provided on the upper surface of the tester shell, a cover plate is slidably connected to the upper surface of the tester shell, plug-in blocks are slidably connected to both sides of the inside of the tester shell, a plug-in slot corresponding to the plug-in block is provided on the lower surface of the cover plate, the plug-in block is slidably plugged into the plug-in slot, four groups of support platforms are provided at the bottom of the tester shell, a placement plate is fixedly installed on the surface of the support platform, a circuit board is detachably connected to the surface of the placement plate, a positioning hole is provided on the upper surface of the circuit board, one end of the support platform passes through the positioning hole, and a fixing component is provided at one end of the support platform.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By pulling the pressing plate downward, the plug-in block slides downward in the first groove, and at the same time, pressure is applied to the first spring to compress the first spring under its own elastic action. When one end of the plug-in block is out of the plug-in slot, the cover plate can be slid to expose the inspection port, so as to inspect the circuit board in the tester housing, solve the problem of cumbersome screw removal, and further improve the inspection speed of the integrated circuit tester.

[0015] 2.

When one end of the support platform is completely inserted into the second groove, the second spring returns to its original state under the action of its own elasticity, and at the same time drives the baffle and the limit block to return to their original position, so that one end of the limit block is reinserted into the jack, which is convenient for re-fixing the repaired circuit board in its original position. When the circuit board needs to be taken out, only the baffle needs to be pressed to move one end of the limit block inward. When the fourth groove and the fifth groove overlap, the card block can be pulled out upward. When one end of the limit block slides out of the fifth groove, the card block is completely separated from the support platform, which is convenient for taking out the circuit board placed on the upper surface of the placement board, thereby overhauling the circuit board.

[0029] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 6As shown, an embodiment of the utility model provides an integrated circuit tester that is easy to repair, including a tester housing 1, an inspection port 2 is provided on the upper surface of the tester housing 1, a cover plate 3 is slidably connected to the upper surface of the tester housing 1, and the cover plate 3 is slidably arranged in a horizontal direction. Both sides of the inside of the tester housing 1 are slidably connected to plug-in blocks 4, and the plug-in blocks 4 are located at the center of the inner side wall of the tester housing 1, so that the cover plate 3 can slide out or slide in from two different directions of the front end or the rear end of the tester housing 1. A plug-in slot 6 corresponding to the plug-in block 4 is provided on the lower surface of the cover plate 3, and the plug-in block 4 is slidably plugged into the plug-in slot 6. Since the tester housing 1 are connected by screws, which means that all bolts need to be removed during the disassembly process to view the internal situation of the tester housing 1, so as to perform maintenance work on the internal components. During the disassembly process, the screws may slip or become thread-locked, which makes it impossible to disassemble the tester housing 1, thereby affecting the maintenance work of the integrated circuit tester. Therefore, by separating the plug-in block 4 from the plug-in slot 6, the connection between the cover plate 3 and the tester housing 1 is changed, so that it is convenient to slide the cover plate 3 to open the inspection port 2, so as to facilitate the maintenance work of the components inside the tester housing 1;

[0031] Four groups of support platforms 7 are arranged at the bottom of the tester housing 1. A placement plate 8 is fixedly installed on the surface of the support platform 7. A circuit board 9 is detachably connected to the surface of the placement plate 8. A positioning hole 10 is opened on the upper surface of the circuit board 9. One end of the support platform 7 passes through the positioning hole 10. The size of the positioning hole 10 is larger than the size of the support platform 7. The positioning hole 10 and the support platform 7 are clearance-matched. The shape of the support platform 7 is the same as that of the positioning hole 10, which makes it convenient to sleeve the support platform 7 into the positioning hole 10, so that the circuit board 9 is placed on the surface of the placement plate 8. A fixing component 5 is arranged at one end of the support platform 7. By removing the fixing component 5 from one end of the support platform 7, the restriction of the fixing component 5 on the circuit board 9 is released, so that the circuit board 9 can be removed from the upper surface of the placement plate 8, thereby improving the disassembly speed of the circuit board 9 and facilitating the inspection and maintenance of the circuit board 9.

[0032] Sliders 11 are provided on both sides of the lower surface of the cover plate 3, and a slide groove 12 corresponding to the slide block 11 is provided on the upper surface of the tester housing 1. The slide block 11 is slidably connected in the slide groove 12. The slide block 11 is set in an inverted T shape, so that the slide block 11 can only slide horizontally in the slide groove 12, and then is plugged into the plug groove 6 through the plug block 4, so that the slide block 11 cannot move horizontally, thereby limiting the cover plate 3 to the upper surface of the tester housing 1 to cover the inspection port 2.

[0033] Fixed blocks 13 are fixedly installed on both sides of the tester housing 1. A first groove 14 is provided on the upper surface of the fixed block 13. The first groove 14 is corresponding to the plug-in slot 6. The plug-in block 4 is slidably connected to the first groove 14. A first spring 15 is provided in the first groove 14. The first spring 15 is fixedly connected to the lower surface of the plug-in block 4. A long hole 16 communicating with the first groove 14 is provided on one side of the tester housing 1. A pressing plate 17 is fixedly installed on one side of the plug-in block 4. One end of the pressing plate 17 passes through the long hole 16. By pulling the pressing plate 17 downward, the plug-in block 4 slides downward in the first groove 14, and pressure is applied to the first spring 15 at the same time, so that the first spring 15 is compressed under the action of its own elasticity. When one end of the plug-in block 4 is out of the plug-in slot 6, the sliding cover plate 3 can be used to expose the inspection port 2, so as to perform maintenance work on the circuit board 9 in the tester housing 1.

[0034] The support platform 7 is hollow at the upper end, a through hole 18 is provided at the bottom of the support platform 7, a threaded hole 19 is provided at the bottom of the tester housing 1, a screw 20 is provided in the support platform 7, one end of the screw 20 passes through the through hole 18 and is threadedly connected to the threaded hole 19. The support platform 7 is fixedly installed at the bottom of the tester housing 1 by the screw 20, which facilitates the installation of the support platform 7.

[0035] The fixing assembly 5 includes a card block 501, a second groove 21 is provided on the lower surface of the card block 501, one end of the support platform 7 is inserted into the second groove 21, two sets of sliding grooves 22 are provided in the second groove 21, and a limited block 502 is slidably connected in the sliding groove 22. One end of the limit block 502 is arranged in an inclined surface, and a socket 23 corresponding to the limit block 502 is provided on the surface of the support platform 7. The limit block 502 is slidably inserted into the socket 23. Third grooves 24 communicating with the sliding grooves 22 are provided on both sides of the card block 501. A second spring 503 is arranged in the third groove 24.

When one end of the support platform 7 is inserted into the second groove 21, one end of the support platform 7 abuts against one end of the inclined surface of the limit block 502, so that the limit block 502 slides outward in the sliding groove 22. At the same time, the baffle 504 drives one end of the second spring 503 to follow the movement, so that the second spring 503 is deformed under the action of its own elasticity. When one end of the support platform 7 is completely inserted into the second groove 21, the second spring 503 returns to its original state under the action of its own elasticity, and at the same time drives the baffle 504 and the limit block 502 to return to their original positions, so that one end of the limit block 502 is reinserted into the socket 23, which is convenient for re-fixing the repaired circuit board 9 in its original position.

[0036] Fourth grooves 25 are provided on both sides of the limit block 502, and the two groups of fourth grooves 25 are symmetrically arranged. A fifth groove 26 connected to the jack 23 is provided on the upper surface of the support table 7.
