Description

Technical Field

[0001] This utility model relates to the field of tester technology, specifically to a structure suitable for a simple programming tester. Background Technology

[0002] In the current field of electronic manufacturing and testing, the programming tester is a key device for chip programming and functional verification. The reliability and ease of operation of the programming tester directly affect production efficiency and product quality. Traditional programming testers usually have many limitations. First, existing programming testers typically require the assembly of dozens or even hundreds of parts, resulting in complex structures and high assembly costs. Specifically, existing programming testers use an integrated plastic encapsulation design after assembling multiple parts. The numerous components lead to complex processing and assembly processes and high costs. Moreover, the encapsulation is not removable, making it difficult to adapt to the subsequent testing requirements of the packaged chips, reducing the utilization rate and flexibility of the tester. In terms of operation, an additional button panel or button structure is required, which not only increases the cost of manual assembly and mold opening, but also may lead to low operating efficiency due to secondary assembly. For example, traditional testers often require external buttons to achieve control functions, which occupies space and increases costs. Therefore, the inventors propose a simplified programming tester structure to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a structure suitable for a simple programming tester, thereby solving the aforementioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A structure suitable for a simple programming tester includes a housing and a circuit board, the circuit board being installed inside the housing; a first connection interface is provided on one side of the housing, and a second connection interface is provided on the other side of the housing; The housing includes a base and a cover plate, wherein the base and the cover plate are detachably connected; At least one button is provided on the cover plate; The circuit board is provided with at least one button, and the button is provided in correspondence with the button.

[0005] According to the above technical solution, the circuit board is installed inside the housing, which consists of a detachable base and a cover plate. One side of the housing has a first connection interface, and the other side has a second connection interface for connecting external devices to transmit data and power. The cover plate has at least one button, and the circuit board has a corresponding button. When the operator presses the button on the cover plate, it triggers the corresponding button on the circuit board, sending a command signal to the circuit board. Upon receiving the signal, the circuit board performs chip programming or testing operations on the connected electronic components according to a preset program. Simultaneously, the programming or testing status during the process is clearly displayed through indicator lights on the circuit board and corresponding light-emitting holes on the cover plate, allowing the operator to intuitively understand the progress. If it is necessary to test electronic components with different chip programming, the base and cover plate can be retained; only the circuit board needs to be removed and replaced to allow the tester to continue functioning, improving its versatility and practicality.

[0006] Furthermore, at least one first lifting column is provided inside the base, and the first lifting column has screw holes.

[0007] Furthermore, the base is provided with a second lifting column inside, and the height of the first lifting column is the same as the height of the second lifting column.

[0008] According to the above technical solution, when the circuit board is installed into the base, since the first and second lifting pillars are of the same height, they can provide stable support for the circuit board from the vertical direction, maintaining a safe distance between the circuit board and the bottom of the base. This effectively avoids the situation where the circuit board is passively raised due to interference from subsequent soldering components, ensuring that the base and cover can be smoothly closed. Moreover, the screw holes in the first lifting pillar, together with the corresponding studs on the cover, can be used to tightly fix the base, circuit board, and cover together with screws and other connectors, forming a stable overall structure. This ensures that the position of each component is accurate and the connection is reliable during the programming and testing process, thereby ensuring that the tester can stably and accurately perform chip programming and various tests on the connected electronic components.

[0009] Furthermore, at least one stud is provided inside the cover plate. When the cover plate is closed with the base, the stud is correspondingly arranged with the first lifting post, and the stud has an internal threaded hole.

[0010] Furthermore, the cover plate is provided with at least one debugging interface slot.

[0011] According to the above technical solution, when the cover plate and base are closed, at least one stud inside the cover plate will precisely correspond to the first raised post with screw holes inside the base. Since the stud has internal threaded holes, screws or other connecting parts can be passed sequentially through the first raised post and the circuit board, and then tightly threaded to the stud, thus firmly fixing the base, circuit board, and cover plate into a whole. This ensures the stability of the tester structure and avoids problems such as component loosening or displacement during programming and testing. Simultaneously, at least one debugging interface slot on the cover plate exposes the debugging interface on the circuit board, allowing software engineers to directly debug the tester's program and set parameters through this interface. This ensures that the tester can accurately program and test the connected electronic components as expected.

[0012] Furthermore, the cover plate has a plurality of light-emitting holes; the circuit board is provided with a plurality of indicator lights, each of which is configured to correspond to one of the light-emitting holes.

[0013] According to the above technical solution, several indicator lights on the circuit board will turn on and off or change color depending on the different test states to provide real-time feedback on the programming test, such as whether the programming was successful or failed, and which stage the test is in. Several light-emitting holes on the cover plate are correspondingly set to each indicator light on the circuit board, allowing the light emitted by the indicator lights to pass through the cover plate without obstruction. Operators do not need to open the tester; they can simply observe the light emitted by the indicator lights at the light-emitting holes on the cover plate to intuitively and clearly understand the ongoing programming test status inside the tester, thereby promptly grasping the work progress and judging the test results.

[0014] Furthermore, it also includes a connector that passes through the first lifting column and the circuit board and is connected to the stud for fixing the base, cover plate and circuit board.

[0015] According to the above technical solution, after the circuit board is placed in the base and the cover plate is initially aligned and closed with the base, the first lifting post in the base, the circuit board, and the stud in the cover plate are in corresponding positions. The connector is passed through the first lifting post and the circuit board in sequence so that it accurately reaches the stud. As the connector is tightened to the stud, a stable fastening force is generated, which tightly combines the base, the circuit board, and the cover plate to form an integral structure, ensuring the stability and reliability of the tester structure and ensuring that the programming test can be carried out accurately and smoothly.

[0016] Furthermore, a stepped strip is formed on the cover plate, and when the cover plate is closed with the base, the stepped strip is engaged in the base.

[0017] According to the above technical solution, when the cover plate is moved towards the base and prepared to close, the stepped strip formed on the cover plate gradually moves closer to the base as the cover plate moves. As the cover plate and the base are fully fitted, the stepped strip precisely engages in a specific position within the base, providing additional limiting and fixing functions between the cover plate and the base without relying on connectors. Even if the tester is subjected to slight impacts from external forces or vibrations caused by the operation of internal components during use, the stepped strip can effectively prevent relative sliding or displacement between the cover plate and the base, ensuring that the overall structure composed of the base, circuit board, and cover plate remains stable at all times. This, in turn, ensures reliable internal circuit connections for the tester, enabling continuous and accurate chip programming and testing.

[0018] Furthermore, a first notch is provided on one side of the base, and a second notch is provided on the other side of the base; A third notch is provided on one side of the cover plate, and a fourth notch is provided on the other side of the cover plate. The first notch and the third notch together form a first connection interface, and the second notch and the fourth notch together form a second connection interface.

[0019] According to the above technical solution, the first notch on one side of the base and the second notch on the other side, along with the third and fourth notches on the corresponding side of the cover plate, play a crucial role in constructing the connection interface. When the cover plate and the base are closed, the first notch on the base and the third notch on the cover plate precisely align and together form the first connection interface. Similarly, the second notch on the base and the fourth notch on the cover plate also precisely align and together form the second connection interface. These two connection interfaces bridge the gap between the tester and external devices for data transmission and power supply. The tester can easily connect to external devices such as computers and electronic components under test, enabling the transmission of chip program writing instructions, test data feedback, and providing necessary power support for the testing process, ensuring the smooth operation of the entire programming test.

[0020] Furthermore, a groove is provided on the top of the cover plate, and a positioning label is pasted in the groove.

[0021] According to the above technical solution, when it is necessary to identify, classify, or record key information (such as the applicable chip model, test parameter range, production batch, etc.) of the tester, the operator can accurately affix the positioning label to the groove. The groove provides a neat placement space for the label, ensuring that the label is flat and firmly fixed, avoiding the label from lifting, falling off, or becoming blurred due to friction or collision during use. When operating, maintaining, or managing multiple testers, operators can quickly and accurately identify the purpose and relevant parameters of the tester simply by checking the information on the positioning label in the groove, greatly improving work efficiency and reducing the risks caused by misoperation or confusion of testers.

[0022] The beneficial effects of this utility model are: This utility model adopts a detachable connection structure between the base and the cover plate. With the first and second lifting columns supporting the circuit board and maintaining a safe distance, the vertical alignment of the cover plate buttons with the circuit board buttons and the slotted on-shell button design eliminates the need for additional button panel assembly, simplifying the operation process and reducing mold costs, thus eliminating the need for redundant structures. The connecting piece passes through the first lifting column and the circuit board, connecting to the cover plate studs for a fixing system that ensures structural stability and supports quick disassembly and replacement of the circuit board to adapt to different chip testing needs, improving equipment versatility and utilization. The step strip's locking design into the base prevents the cover plate from sliding or shifting even without screws. Combined with the circuit board debugging interface exposed in the debugging interface slot, it achieves dual optimization of production efficiency and testing convenience. The precise alignment of the light-emitting hole and the indicator light provides real-time feedback on the programming / testing status, ultimately forming a comprehensive technical advantage of simplified structure, reduced cost, convenient operation, and strong versatility.
