Detailed Implementation

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] A test fixture for a modular circuit board includes: a test circuit board 1 and a housing 2. The test circuit board 1 is fixed inside the housing 2. Multiple connectors 1-1 are provided on the test circuit board 1. The modular circuit board to be tested is connected to the test circuit board 1 through the connectors 1-1. The test circuit board 1 is used to test the modular circuit board to be tested. Multiple connector slots 2-1 and multiple fixing slots are provided on the housing 2. The connectors 1-1 are fixed inside the connector slots 2-1. The connector slots 2-1 are arranged inside the fixing slots or on one side edge outside the fixing slots. The fixing slots fix the modular circuit board to ensure that the modular circuit board will not vibrate during the test, thereby ensuring the stability of the modular circuit board test.

[0025] In this embodiment, multiple test areas can be set on the test circuit board 1, each test area has a different test function, and a connector 1-1 is set on each test area for testing module circuit boards with different functions. As an alternative implementation, the test circuit board 1 has a single test function, and multiple connectors 1-1 are set on the test circuit board 1 for testing module circuit boards with the same function but different shapes.

[0026] The fixing slots include snap-fit ​​fixing slots 2-2 and plug-in fixing slots 2-3 respectively arranged on the two end faces of the housing 2. The snap-fit ​​fixing slots 2-2 and plug-in fixing slots 2-3 are staggered and have opposite openings. The staggered snap-fit ​​fixing slots 2-2 and plug-in fixing slots 2-3 reduce the required thickness of the housing 2, making it easier to store this test fixture. At the same time, the snap-fit ​​fixing slots 2-2 and plug-in fixing slots 2-3 can fix different module circuit boards respectively to ensure the stability of the module circuit board during the test process.

[0027] The housing 2 includes a first housing 2-18 and a second housing 2-19 that are assembled together. The second housing 2-19 is provided with a through groove 2-13, and the first housing 2-18 is provided with a plug-in groove 2-14. The through groove 2-13 and the plug-in groove 2-14 are assembled to form a plug-in fixing groove 2-3. A snap-fit ​​fixing groove 2-2 is arranged on the first housing 2-18, and the depth of the first fixing groove is less than the thickness of the first housing 2-18.

[0028] A partition plate 2-4 is provided in the snap-fit ​​fixing groove 2-2, which divides the snap-fit ​​fixing groove 2-2 into a support groove 2-5 and a slot 2-6. A connector 1-1 is provided in the support groove 2-5 and the slot 2-6 respectively. The support groove 2-5 is used to fix the module circuit board in a horizontal state, and the slot 2-6 is used to fix the module circuit board in a vertical state, so as to meet the connection of different types of module circuit boards with connector 1-1.

[0029] To facilitate the stable placement of the module circuit board within the support groove 2-5, a support rib 2-7 and a connector rib 2-8 are connected to the inner wall of the support groove 2-5. The support rib 2-7 is connected to the inner side wall of the support groove 2-5, and the connector rib 2-8 is connected to the partition plate 2-4, forming a connector groove 2-1 on one side of the partition plate 2-4 for assembling the connector 1-1. The top surfaces of the support rib 2-7 and the connector rib 2-8 are at the same height to facilitate the support of the module circuit board through the support rib 2-7 and the connector rib 2-8.

[0030] On the inner wall of slot 2-6, there are guide ribs 2-9 arranged opposite to each other. A plug-in gap 2-10 is formed between the guide ribs 2-9 for plugging in the module circuit board. By setting the guide ribs 2-9, the module circuit board can be fixed in a vertical state. At the same time, the contact area between slot 2-6 and the surface of module circuit board can be reduced, preventing slot 2-6 from damaging the components on module circuit board.

[0031] The partition plate 2-4 is provided with a connecting plate 2-11 at its end. The partition plate 2-4 is connected to the inner wall of the snap-fit ​​fixing groove 2-2 through the connecting plate 2-11, thereby ensuring that the partition plate 2-4 has good strength. Preferably, the connecting plate 2-11 is arranged on one side of the slot 2-6.

[0032] Insertion ribs 2-12 are provided on the inner wall of the insertion fixing groove 2-3. A circuit board slot 2-17 for inserting the module circuit board is formed between adjacent insertion ribs 2-12. The insertion ribs 2-12 are T-shaped and include a horizontal plate 2-15 and a vertical plate 2-16. The horizontal plate 2-15 is connected to the inner wall of the circuit board slot 2-17 through the vertical plate 2-16. The circuit board slot 2-17 is formed between adjacent horizontal plates 2-15.
