Embodiment Construction

[0016] see figure 1 and figure 2 , the electromagnetic compatibility test fixture 1 of the present invention is used to assist a server 100 under test to perform electromagnetic compatibility test.

[0017] The cross-section of the test fixture 1 is generally in the shape of an "I", which includes two side plates 10 parallel to each other and a partition plate 20 vertically connected to the inner middle of the two side plates 10 . A through hole 21 is defined in the middle of the partition 20 . The upper and lower sides of the separator 20 and the inner side of the side panels 10 are all pasted with conductive foam 30 .

[0018] Please also refer to figure 2 and image 3 , the test fixture 1 can be sandwiched between the server under test 100 and an auxiliary test server 200 to facilitate the electromagnetic compatibility test of the server under test 100 . The server 100 to be tested is a server without a top cover, which includes a bottom wall 101 and four side walls ...

Abstract

An electromagnetic compatibility test fixture comprises two parallel side plates and a partition plate vertically connected to the middle parts of the inner sides of the two side plates. The middle of the partition plate is provided with a through hole. The upper and lower sides of the partition plate and the inner sides of the two side plates are pasted with conductive foam. The invention further provides a method for testing the electromagnetic compatibility of a server without an upper cover by use of the test fixture. Compared with the prior art, the electromagnetic compatibility test fixture can be clamped between a to-be-tested server and an auxiliary server so as to test the electromagnetic compatibility of the to-be-tested server, which facilitates operation, ensures that electromagnetic leakage is not caused, and makes test results accurate.

Description

technical field [0001] The invention relates to an electromagnetic compatibility testing jig and a testing method using the jig. Background technique [0002] According to the requirements of the Electro Magnetic Compatibility (Electro Magnetic Compatibility) directives of various countries, electronic products need to undergo electromagnetic compatibility testing before entering the country's market. Only products that meet the country's electromagnetic compatibility standards can be sold in the country's market. For a server without a cover, in the electromagnetic compatibility test, because it has no cover, another server is manually placed on the server to be tested for testing, and the two servers are often not completely aligned, which is not only inconvenient for testing It can also cause inaccurate test results. Contents of the invention [0003] In view of the above, it is necessary to provide an EMC test fixture that is convenient for EMC testing and a testing m...
