Description
Technical Field
The utility model relates to a multi-channel adapter needle structure.
Background
With the development of industrial technologies, the requirements of consumer groups on the performance and reliability of electronic products are improved, and the requirements of high-demand testing are required, so that the stable testing of various consumer electronic products becomes an important means for ensuring and improving the performance and reliability of the consumer electronic products. The multi-channel test is continuously upgraded while the requirement is stably tested, the test requirements of more products can be met, and the multi-channel test system has the advantages of high test efficiency, high reliability of test results and the like. The prior art is mostly a single-channel signal switching technology, has simple test requirements, and is not suitable for more test requirements and more complex product tests. Therefore, a multi-channel adapter pin structure which is compact in structure, stable in test and capable of realizing multi-channel test needs to be developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides a multi-channel adapter pin structure which is compact in structure, stable in test and capable of realizing multi-channel test.
The technical scheme adopted by the utility model is as follows: the test board assembly comprises a test board, a needle plate assembly, a carrier board assembly, a pressure plate assembly and a transfer plate which are sequentially arranged from bottom to top, wherein a lower transfer needle matched with the test board is arranged on the needle plate assembly, a through hole is formed in the carrier board assembly, an upper transfer needle matched with the transfer plate is arranged on the pressure plate assembly, the upper end of the lower transfer needle is matched with the lower end of the upper transfer needle, and a plurality of test stations are arranged on the carrier board assembly.
Furthermore, the upper end of the lower connecting needle is a telescopic tip.
Further, the lower end of the upper transfer needle is a butt end.
Furthermore, the upper end of the lower transfer needle penetrates through the through hole and is matched with the lower end of the upper transfer needle.
The utility model has the beneficial effects that: the utility model adds the switching technology on the basis of not influencing the original test structure, is well applied to the test fixture with limited space, has compact structure and small occupied area of the fixture; in addition, the utility model adopts the upper and lower separated switching, is suitable for the movable test structure, meets the requirement of multi-channel test, and has high efficiency and stability.

Detailed Description
As shown in fig. 1 to 6, in this embodiment, the test board assembly of the present invention includes a test board 1, a needle plate assembly 2, a carrier board assembly 3, a pressure plate assembly 4, and a patch panel 5, which are sequentially arranged from bottom to top, wherein a lower patch pin 6 matched with the test board 1 is arranged on the needle plate assembly 2, a through hole 7 is formed on the carrier board assembly 3, an upper patch pin 8 matched with the patch panel 5 is arranged on the pressure plate assembly 4, an upper end of the lower patch pin 6 is matched with a lower end of the upper patch pin 8, and a plurality of test stations are arranged on the carrier board assembly 3; during testing, a product is placed on the carrier plate component 3, the product collects a pin point signal on the adapter plate 5 through the probe, and the signal is transmitted to the test board 1 through the upper adapter pin 8 and the lower adapter pin 6. Compared with the defects of the prior art, in the utility model, during testing, the press plate component 4 presses down and presses down the carrier plate component 3, the press plate component 4 with the carrier plate component 3 presses down on the needle plate component 2, so that the press plate component 4, the carrier plate component 3 and the needle plate component 2 are integrally pressed, a product on the carrier plate component 3 collects a needle point signal on the adapter plate 5 through a probe, the adapter plate 5 is communicated with the test plate 1 through the contact of the upper adapter pin 8 and the lower adapter pin 6, and then the signal is switched on the test plate 1, therefore, the utility model can meet more test requirements through the arrangement of the upper adapter pin 8 and the lower adapter pin 6, can realize multi-channel signal switching, realizes better signal transmission, provides an efficient and stable test environment, and has a compact structure, The test is stable and the multi-channel test can be realized.
In this embodiment, the upper end of the lower transfer needle 6 is a retractable tip. So that the upper end of the lower transfer needle 6 can elastically contact with the lower end of the upper transfer needle 8 to reduce impact and ensure good contact.
In this embodiment, the lower end of the upper transfer needle 8 is a butt end.
In this embodiment, the upper end of the lower adapter pin 6 passes through the through hole 7 and is matched with the lower end of the upper adapter pin 8.
While the embodiments of the present invention have been described in terms of practical embodiments, they are not to be construed as limiting the meaning of the present invention, and modifications of the embodiments and combinations with other embodiments will be apparent to those skilled in the art in light of the present description.
