Description

Technical Field

[0001] This utility model relates to the field of electrical performance testing technology, specifically to an electrical performance testing device for multi-point connectors. Background Technology

[0002] With the development of the IT industry, the number of CPU pins has increased to improve CPU data processing speed and computing power. Due to the continuous increase in CPU connector pins, traditional CPU connector testing methods struggle to complete electrical performance testing comprehensively and accurately, requiring multiple instruments or multiple probes, which easily leads to missed tests and misjudgments. While imported instruments can perform comprehensive testing, their cost is nearly 30 times higher than conventional instruments, and their testing efficiency is low. Therefore, to solve these problems, multiple instruments or multiple probes are generally used to complete the testing.

[0003] Currently, traditional video display devices have the following problems:

[0004] 1. When using multiple instruments for electrical performance testing, the large number of pins on the connector module makes the point allocation for each instrument complex. Furthermore, the high redundancy of test points allocated to different areas by each instrument can easily lead to missed tests or misjudgments. Additionally, when test results are abnormal, it is difficult to quickly locate the problem using multiple instruments; diagnosis requires consulting the documentation for each instrument, which is inconvenient and costly.

[0005] 2. When using multiple probes for electrical performance testing, the time and design costs are high, requiring the testing instruments and mechanical structures to work together to complete multiple tests. Furthermore, the frequent use of multiple probes leads to accelerated wear on the test pins, reducing their lifespan and increasing testing costs. Utility Model Content

[0006] The purpose of this invention is to provide an electrical performance testing device for multi-point connectors to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] The electrical performance testing device for multi-point connectors provided by this utility model includes a test chassis, a test rack, performance testing components, and a test base module.

[0009] The test base module is installed inside the test chassis, and a connector module is clamped and positioned on the top of the test base module.

[0010] Preferably, a connecting arm is installed inside the test rack, and the connecting arm is located on the side of the performance testing component.

[0011] The bottom of the connecting arm is fitted with a control terminal by screws, and the control terminal is electrically connected to the performance testing component and the test base module respectively.

[0012] Preferably, the performance testing component includes:

[0013] A test bracket is mounted on the top of the test chassis by screws. The test bracket is located inside the test frame, and multiple guide cylinders are mounted on the top of the test bracket.

[0014] A pressure servo cylinder is installed at the center of the top of the test bracket. The pressure servo cylinder is located on the side of multiple guide cylinders. The output end of the pressure servo cylinder penetrates through the test bracket and is connected to an assembly plate.

[0015] The bottom of the assembly plate is equipped with a horizontal compensation component;

[0016] A guide rod is provided, which passes through the guide cylinder. Multiple guide rods are provided, and all of the multiple guide rods are installed on the top of the assembly plate. A baffle is installed on the top of the multiple guide rods.

[0026] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0027] 1. Customized test motherboards and adapter boards are designed for specific connector applications. During use, the test motherboard brings out all required test pins via a product test fixture, and the adapter board transfers these pins to the switching board. The number of switching boards can be increased as the number of required pins grows, with each switching board corresponding to one interface on a traditional test instrument. The switching board is divided into eight zones, each corresponding to a different area of ​​the CPU connector, and corresponding documentation is created on the traditional test instrument according to testing requirements. During testing, the control terminal controls the continuity of different areas on the switching board, and the documentation on the traditional test instrument performs continuity and withstand voltage tests on that area of ​​the CPU connector. This process allows for the completion of the entire connector testing operation with the fewest contact attempts and in the shortest time.

[0028] 2. Compared with existing technologies, it significantly reduces design and implementation time and costs, and solves the problems of missed tests and misjudgments. If an abnormal point is detected during testing, it can be quickly located and recorded. Furthermore, it eliminates the need for repeated contact with the connector pins during testing, reducing testing time and connector wear, and extending connector lifespan.

[0040] Please see Figures 1-4The electrical performance testing device for multi-point connectors includes a test chassis 10, a test rack 20, a performance testing component 30, and a test base module 40. The test rack 20 is installed at the top corner of the test chassis 10. The performance testing component 30 is installed inside the test rack 20. The performance testing component 30 is located above the test base module 40. The test base module 40 is installed inside the test chassis 10. A connector module is clamped and positioned on the top of the test base module 40.

[0041] In practical use, the connector module to be tested is mounted on top of the test base module 40. The internal components of the test base module 40 divide the connector module's internal points into eight regions (a total of 256 input points and 64 output points). Each point corresponds to a pin on the connector module and an interface of the electrical testing machine, achieving electrical performance testing of a large number of connector points through superposition. During actual testing, the performance testing component 30 operates, enabling automated electrical performance testing with high efficiency.

[0042] The test rack 20 has a connecting arm 201 installed inside. The connecting arm 201 is located on the side of the performance test component 30. The bottom of the connecting arm 201 is fitted with a control terminal 202 by screws. The control terminal 202 is electrically connected to the performance test component 30 and the test base module 40 respectively.

[0043] This utility model discloses a multi-point connector electrical performance testing device. Through the design of the control terminal 202, during each test, the control terminal 202 can sequentially control the relays in eight areas of the test base module 40 to conduct the connection between the connector module and the electrical testing machine, thereby realizing the electrical performance testing of the connector module. It can perform testing on up to 256 electrical testing machine interfaces per test, which is four times that of conventional testing operations.

The test bracket 301 is located inside the test frame 20, and multiple guide cylinders 302 are mounted on the top of the test bracket 301. A pressure servo cylinder 303 is mounted at the center of the top of the test bracket 301 and is located on the side of the multiple guide cylinders 302.

[0047] This utility model discloses an electrical performance testing device for multi-point connectors. When performing electrical performance testing on connector modules, the device activates a pressure servo cylinder 303, which drives the assembly plate 304 connected to its output end to move vertically. This allows the horizontal compensation component 305 mounted at the bottom of the assembly plate 304 to move vertically, thus automating the connector module testing (withstand voltage capability). The design of the guide rod 306 and guide cylinder 302 guides the vertical movement of the assembly plate 304, ensuring that the assembly plate 304 moves vertically only in the vertical direction.

[0048] The horizontal compensation component 305 includes a test module 3051, which is slidably disposed at the bottom of the assembly plate 304. One side of the test module 3051 is connected to the output end of the horizontal cylinder 3052, which is mounted on the side of the assembly plate 304. A pressure-resistant probe 3053 is mounted at the bottom of the test module 3051 and performs a pressure-resistant test on the connector module disposed at the bottom.

[0049] The electrical performance testing device for multi-point connectors of this utility model allows the test module 3051 and the withstand voltage probe 3053 to be moved horizontally by operating the horizontal cylinder 3052 when performing electrical performance testing on the connector module, thereby adjusting the position (horizontal direction) of the test module 3051 and the withstand voltage probe 3053.

[0050] The basic test module 40 includes a test host 401, a switching board 402, a support bracket 403, an adapter board 404, a test motherboard 405, and a product test fixture 406.

The top of the test host 401 extends to the top of the test chassis 10. A support bracket 403 is installed on the outer side of the top of the test host 401. The support bracket 403 is installed on the top of the test chassis 10. The test motherboard 405 is installed on the top of the support bracket 403. Multiple adapter boards 404 are installed at the top edge of the test motherboard 405. The product test fixture 406 is installed on the side of the adapter board 404. The product test fixture 406 is installed at the center of the top of the test motherboard 405. A connector module is clamped and fixed on the inner side of the product test fixture 406.

[0051] This utility model discloses a multi-point connector electrical performance testing device. The test host 401 provides power for the electrical performance testing of the connector module. Several pins of the connector module are connected to the interface of a conventional electrical testing machine via a product testing fixture 406, a test main board 405, an adapter board 404, and a switching board 402. In use, the product testing fixture 406, test main board 405, and adapter board 404 are assembled together, and then the switching board 402 and the electrical testing machine are connected via wiring. Each switching board 402 is divided into 8 areas, with a total of 256 input points and 64 output points, corresponding to the 256 pins of the connector module and one interface of the electrical testing machine, respectively.
