Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, and in particular to a multifunctional circuit board functional tester. Background Technology

[0002] With the rapid development of electronic technology, circuit boards, as the core component of various electronic devices, directly affect the working status of the entire machine in terms of performance and reliability. To ensure the normal functioning of circuit boards during production and use, multi-functional testers have become an indispensable tool in production testing, maintenance and debugging. Currently, most multi-functional circuit board testers on the market have multiple test interfaces, which can test multiple functions of circuit boards such as electrical performance, signal integrity and load capacity, greatly improving testing efficiency and accuracy.

[0003] A utility model patent application with publication number CN213398818U discloses a circuit board tester with dustproof function, including a tester housing. A movable door is movably installed at the upper end of the housing, and a handle is welded and fixed to the movable door. An indicator light is fixedly installed below the movable door, a VGA interface is fixedly installed below the indicator light, and a USB port is fixedly installed below the VGA interface. A display screen is fixedly installed in the middle of the housing, and a circuit board connector is fixedly installed below the display screen. Shock-absorbing springs reduce vibrations caused by impacts and violent movements, better protecting internal components and preventing misalignment due to vibration. When not in use, the movable door is closed to prevent dust from accumulating at the connectors, causing poor contact and affecting test results and accuracy.

[0004] The above technical solution achieves dust protection for the interface by closing the movable door. However, due to the presence of shock-absorbing springs, the top of the tester's outer casing is not closed. The presence of the shock-absorbing springs creates a gap between the instrument itself and the casing. Furthermore, the movable door is a flat design, while the interface and socket protrude from the circuit board socket. This means that when the movable door is closed, there is a gap between the movable door and the interface or socket. Even when the movable door is closed, dust can still contaminate the interface or socket, resulting in a decrease in the dust protection effect. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional circuit board function tester, which solves the problem of poor dust prevention in existing multifunctional circuit board function testers by setting a dust prevention mechanism.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0023] Please see Figures 1-3This is the first embodiment of the present invention, which provides a multifunctional circuit board functional tester, including a tester body 1, a buffer pad 2 mounted on the surface of the tester body 1, a protective shell 3 mounted on the surface of the buffer pad 2, a dustproof mechanism 4 provided in front of the protective shell 3, the dustproof mechanism 4 including a sealing plate 41 disposed on the front side of the protective shell 3, sealing strips 42 respectively mounted on both sides of the front side of the protective shell 3, a protective plate 43 mounted on the rear side of the sealing strips 42, a protective pad 44 mounted on the rear side of the protective plate 43, and an adjustment component 49 disposed in front of the protective plate 43. The dust collection mechanism 4 also includes grooves 45 respectively opened on both sides of the rear of the sealing plate 41, magnets 46 installed inside the grooves 45, a fixing plate 47 installed on the front side of the top of the protective shell 3, and iron plates 48 respectively installed on both sides in front of the fixing plate 47. The sealing plate 41 and the protective shell 3 are slidably connected. Slider blocks are fixedly connected to the bottom of both sides of the sealing plate 41. The protective shell 3 has a sliding groove adapted to the slider on the side near the sealing plate 41. The sealing strip 42 is in contact with the sealing plate 41, the protective plate 43 and the protective pad 44. The tester body 1 is in contact with the protective pad 44.

[0024] The tester body 1 is a special electronic test device used for detecting and diagnosing multiple functions such as the function, performance and faults of circuit boards. It has various connection interfaces on the front side, and three circuit board test ports are installed in the center of the front side. Its specific composition and function are existing mature technologies and will not be described in detail here. The buffer pad 2 plays a buffering role to protect the internal structure of the tester from external impact or vibration. The protective shell 3 is used to fix and encapsulate the tester body 1 and other components. Both the protective shell 3 and the buffer pad 2 have heat dissipation holes on the top, and dustproof mesh is installed inside the heat dissipation holes.

[0025] The dustproof mechanism 4 is used to provide closed dust protection for the front interface area of ​​the tester body 1 when it is not in use. The sealing plate 41, as the main closing component of the dustproof mechanism 4, can slide to close when the tester body 1 is not in use, covering the front of the tester body 1 and blocking dust. The sealing strip 42 is in close contact with the sealing plate 41, the protective plate 43, the protective pad 44 and other components to enhance the sealing performance and prevent dust from entering from the gaps. The protective plate 43 can move up and down to cover part of the unused circuit board test ports. The magnet 46 cooperates with the iron plate 48 on the front side of the fixing plate 47 to achieve magnetic fixation when the sealing plate 41 is opened, which is convenient for operation.

[0026] When the circuit board needs to be tested during operation, the sealing plate 41 is pulled up by the handle until the tester body 1 is exposed. The opening sealing plate 41 is then magnetically fixed by the iron plate 48 and the magnet 46, allowing the tester body 1 to be connected normally. The circuit board is then inserted into the circuit board test socket for testing. When not in use, the sealing plate 41 is reset. The sealing strip 42, protective plate 43, protective pad 44, protective shell 3, and sealing plate 41 together form a seal to seal the front area of ​​the tester body 1 and prevent dust, achieving a good dustproof effect. Example 2

[0027] Please see Figures 4-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] Specifically, the adjustment assembly 49 includes a movable groove 491 located behind the sealing plate 41, a movable strip 492 slidably connected inside the movable groove 491, an observation plate 493 located on the front side of the movable strip 492, a limiting pin 494 inserted into the front side of the observation plate 493, a positioning hole 495 located on the front side of the movable strip 492, and limiting blocks 496 respectively installed on both sides of the movable strip 492. The size of the movable groove 491 is adapted to the movable strip 492. Limiting grooves adapted to the limiting blocks 496 are provided on both sides inside the movable groove 491. The front section of the limiting pin 494 is threaded, and the rear section of the limiting pin 494 is smooth. The size of the positioning hole 495 is adapted to the rear section of the limiting pin 494.

[0029] Adjustment component 49 is used to control the position of protective plate 43. It can select to block part of the circuit board detection interface according to the actual use, so as to achieve flexible dust prevention. The rear side of the movable strip 492 extends to the rear side of the sealing plate 41 and is installed in front of the protective plate 43. The protective plate 43 and the sealing plate 41 are in close contact. The observation plate 493 is made of transparent material, which makes it easy to observe the position of the protective plate 43. The sealing plate 41 is installed on the surface of the observation plate 493. The protective plate 43 and the protective pad 44 are in contact with the bottom of the limit pin 494. The threaded section of the limit pin 494 can be threadedly connected to the observation plate 493. There are two positioning holes 495, so that the limit pin 494 can be inserted into the two positioning holes 495 from bottom to top, which can respectively block the top two and the top one of the three circuit board interfaces for dust prevention.

[0030] When the sealing plate 41 is opened and the tester body 1 is used, the limit pin 494 is pulled out. The protective plate 43 and the protective pad 44 move down under the action of gravity to block the circuit board test port. At this time, the movable strip 492 slides inside the movable groove 491. Depending on the specific use, the number of reserved circuit board test ports can be selected. The plate can be moved up and the limit pin 494 can be inserted into the corresponding positioning hole 495 to fix the position of the protective plate 43, so as to protect the unused circuit board test ports from dust and further improve the dustproof effect. Example 3

[0031] Please see Figure 1 and Figure 2 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0032] Specifically, a handle is fixedly connected to the front side of the sealing plate 41, and a limit hole 5 is opened at the bottom front side of the tester body 1.

[0033] The size of the limiting hole 5 is also compatible with the size of the smooth section of the limiting pin 494. When the sealing plate 41 is in the sealing protection tester body 1, the limiting pin 494 is threadedly connected to the observation plate 493. At this time, the smooth section of the limiting pin 494 is inserted into the limiting hole 5, thereby limiting the sealing plate 41 as a whole to prevent it from moving, and further improving the dustproof effect.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
