Description

Technical Field

[0001] This utility model relates to the field of mixed-signal testing machine technology, and in particular to a modular probe interface switching device for a mixed-signal testing machine. Background Technology

[0002] In the field of mixed-signal testing, traditional interface switching devices mainly consist of fixed interfaces and basic switching circuits. Their principle is to guide test signals to the corresponding channels of the mixed-signal tester via manual connection or simple mechanical devices, thereby achieving signal switching between different test points. These devices have a relatively simple structure, typically consisting of a main frame, several fixed interfaces, and basic circuit switching elements, such as relays or simple semiconductor switches. Their signal transmission path is relatively fixed, and the switching function is also quite basic, mainly relying on external operation or simple control signals to change the signal flow.

[0003] Existing technologies, such as some early interface switching devices, while capable of basic signal switching, have certain limitations. Firstly, their heat dissipation performance needs improvement. During testing, especially during prolonged, high-frequency signal switching operations, heat is generated at the interface and internal circuitry. Due to the lack of efficient heat dissipation structures, this heat accumulation can lead to increased interface temperature, affecting the stability and accuracy of signal transmission, and potentially damaging interface components. Secondly, the interface fixing method is not robust enough. Existing devices mostly use simple plug-and-play interfaces, which are prone to loosening and falling off in test scenarios susceptible to vibration or requiring long-term stable connections, causing signal interruptions and affecting test continuity. These problems, to some extent, restrict the efficiency and reliability of mixed-signal testing, especially when facing complex and diverse modern testing requirements, where the shortcomings of existing technologies become more apparent. This invention addresses these problems by proposing a modular probe interface switching device. By optimizing the heat dissipation structure, improving the interface fixing method, and enhancing interface expandability, it effectively solves the deficiencies of existing technologies and improves the overall performance of mixed-signal testing. Utility Model Content

[0004] The purpose of this invention is to provide a modular probe interface switching device for a mixed-signal testing machine, which can overcome the shortcomings of existing devices.

[0005] To achieve the above objectives, a modular probe interface switching device for a mixed-signal tester is provided, comprising a heat dissipation base, a mixed-signal tester body mounted on the upper side wall and near the rear of the heat dissipation base, a connector conversion device body mounted on the upper side wall of the heat dissipation base and directly in front of the mixed-signal tester body, and a plurality of connection slots provided on the front side wall of the connector conversion device body, wherein a probe interface body is installed inside the connection slots. The front sidewall of the connector conversion device body and located directly above the connection slot is provided with a sliding inner groove. A sliding block is slidably connected inside each sliding inner groove. Two positioning pieces are slidably connected inside the upper sidewall of each connection slot. A heat-conducting block is fixedly connected inside the connector conversion device body and located between adjacent probe interface bodies.

[0006] According to the modular probe interface switching device of the mixed-signal tester, the heat dissipation base is provided with a circulating water pipe inside, and a heat-conducting pipe is installed at the upper end of the circulating water pipe. The heat-conducting pipe is located inside the heat-conducting block, and the circulating water inside the heat-conducting pipe can remove the heat from the heat-conducting block.

[0007] According to the modular probe interface switching device of the mixed-signal tester, the heat dissipation base is provided with a heat dissipation fan bracket, which can effectively accelerate the heat dissipation efficiency of the circulating water pipe.

[0008] According to the modular probe interface switching device of the mixed-signal tester, the front and rear side walls of the heat sink are provided with dustproof nets, which can effectively reduce the entry of external dust into the heat sink.

[0009] According to the modular probe interface switching device of the mixed-signal testing machine, the front sidewall of the sliding block is provided with anti-slip texture.

[0010] According to the modular probe interface switching device of the mixed-signal tester, the left and right sides of the sliding block are fixedly connected with connecting plates. The sliding block is connected to the positioning plate through the connecting plates. The sliding block moves up and down, and the positioning plate moves up and down through the connecting plates. The positioning plate can fix the plug inserted into the probe interface body, effectively preventing the plug from falling off.

[0011] According to the modular probe interface switching device of the mixed-signal tester, the connecting piece is symmetrically arranged about the probe interface body to improve the fixing effect of the plug.

[0012] According to the modular probe interface switching device of the mixed-signal tester, the circulating water pipe is spirally wound inside the heat dissipation base, and the heat conduction pipe and the interior of the circulating water pipe are filled with circulating water.

[0013] This utility model has the following beneficial effects: 1. Compared with existing technologies, this device can securely fix the plug inserted into the probe interface body through the ingenious cooperation of the sliding block, positioning piece and connecting piece in the main body of the connector conversion device. It can effectively prevent the plug from loosening or falling off due to vibration and other factors, ensure the continuity and stability of signal transmission, improve test efficiency and reliability, reduce the risk of test interruption and error caused by connection problems, and adapt to a variety of complex test scenarios.

[0014] 2. Compared with existing technologies, the heat sink base is equipped with circulating water pipes and heat conduction pipes, which, together with the cooling fan bracket and cooling fan, form a highly efficient heat dissipation system. The heat conduction block can quickly absorb the heat generated by the probe interface body during operation and transfer it to the circulating water in the heat conduction pipes for removal. The cooling fan accelerates the airflow within the heat sink base, further improving heat dissipation efficiency. This excellent heat dissipation design ensures that the connector conversion device body and the mixed-signal testing machine body operate in a stable and suitable temperature environment, extending the service life of the equipment, improving testing accuracy and stability, and ensuring the continuity and reliability of testing work.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4 This utility model discloses a modular probe interface switching device for a mixed-signal testing machine. It includes a heat dissipation base 1, which serves as the fundamental support structure of the entire device. Made of highly thermally conductive aluminum alloy, it exhibits excellent heat dissipation performance. A circulating water pipe 205 is spirally wound inside the heat dissipation base 1, increasing the contact area between the pipe and the cooling air and improving heat dissipation efficiency. A heat-conducting pipe 2051 is installed at the upper end of the circulating water pipe 205, extending into a heat-conducting block 204 inside the connector conversion device body 2. This heat-conducting pipe transfers the heat absorbed by the heat-conducting block 204 to the circulating water in the circulating water pipe 205, where the heat is carried away, effectively dissipating heat from the connector conversion device body 2. A cooling fan bracket 102 is also installed inside the heat dissipation base 1, with a cooling fan mounted on it. When the cooling fan operates, it accelerates the airflow inside the heat dissipation base 1, further improving its heat dissipation efficiency and ensuring that the heat generated during operation is dissipated promptly, guaranteeing stable operation of the device.

[0019] The connector conversion device body 2 is mounted on the upper side wall of the heat dissipation base 1 and located directly in front of the mixed-signal testing machine body 3. Its front side wall has several connection slots 203 arranged in a matrix to accommodate different numbers and specifications of probe interface bodies 202. Each connection slot 203 houses a probe interface body 202, which connects to probes from external testing equipment to transmit and switch signals. A sliding inner groove 201 is located on the front side wall of the connector conversion device body 2, directly above the connection slots 203. This sliding inner groove 201 provides a track for the sliding block 4, allowing it to slide stably along the groove, thereby driving the positioning piece 401 to fix or release the plug inserted into the probe interface body 202. A heat-conducting block 204 is fixedly connected inside the connector conversion device body 2 and between adjacent probe interface bodies 202. The heat-conducting block 204 is made of copper material with high thermal conductivity, which can quickly absorb the heat generated by the probe interface body 202 during operation and transfer it to the heat-conducting pipe 2051. Then, the heat is carried away from the device by the circulating water in the circulating water pipe 205, effectively reducing the temperature of the connector conversion device body 2 and ensuring the normal operation of the probe interface body 202.

[0020] The sliding block 4 is slidably connected inside the sliding inner groove 201. Its front sidewall is provided with anti-slip texture, which facilitates the operator's manual sliding operation and prevents slippage during sliding. Connecting pieces 402 are fixedly connected to both the left and right sides of the sliding block 4. The connecting pieces 402 are symmetrically arranged about the probe interface body 202. The sliding block 4 is connected to the positioning piece 401 via the connecting pieces 402. When the operator pushes the sliding block 4 up and down, the sliding block 4 drives the positioning piece 401 to move up and down via the connecting pieces 402. The positioning piece 401 is located inside the upper sidewall of the connecting slot 203. When the positioning piece 401 moves downwards, it can fix the plug inserted into the probe interface body 202, preventing the plug from falling off due to vibration or other external forces during testing, ensuring the reliability of the connection. When it is necessary to remove the plug, moving the sliding block 4 upwards causes the positioning piece 401 to move upwards as well, thus releasing the fixation on the plug and facilitating its removal. This cooperative structure of sliding block 4 and positioning piece 401 is simple and convenient to operate, and can effectively improve the stability of the connection between probe interface body 202 and plug.

[0021] Dustproof nets 101 are installed on both the front and rear side walls of the heat dissipation base 1. The dustproof nets 101 are made of high-density filter material, which can effectively filter dust and impurities in the air and prevent external dust from entering the interior of the heat dissipation base 1. While ensuring good ventilation and heat dissipation of the heat dissipation base 1, dust accumulation on components such as the circulating water pipe 205, the cooling fan bracket 102, and the connector conversion device body 2 is avoided, thereby affecting the heat dissipation performance and normal operation of the device and extending the service life of the device.

[0022] Through the coordinated operation of the above-mentioned devices or mechanisms, the modular probe interface switching device of the mixed-signal tester can achieve efficient and stable signal switching function, while having good heat dissipation and dustproof performance, effectively improving the reliability and stability of the mixed-signal tester during operation, and providing a strong guarantee for the accurate conduct of testing.

[0023] Unless otherwise specified, the constituent units of this utility model are obtained from conventional commercial channels or manufactured by conventional methods. Their specific structure, working principle, and possible control methods and spatial arrangement methods can adopt conventional choices in the field and should not be regarded as the innovation of this utility model. This is understandable to those skilled in the art, and this utility model patent will not be further elaborated in detail.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
