Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of optical module test equipment, and specifically relates to a scratch-proof device applied to a high-speed optical module test system. BACKGROUND

[0002] Optical modules play a key role in the field of data communication, especially high-speed optical modules such as 400G and 800G. The stability of the optical modules is crucial to the quality of the optical modules. In order to ensure that the optical modules can be used stably for a long time, the optical modules need to be strictly tested for multiple projects before being shipped. During these tests, the optical modules need to be plugged in and moved multiple times on different test equipment and test stations. Therefore, it is necessary to ensure that the connection between the optical modules and the test equipment is stable and accurate, and at the same time, the optical modules should not be scratched during the plugging operation to avoid affecting their performance and appearance. Especially in high and low temperature test projects, test operators need to wear protective devices, and the requirement for scratch-proofing of the optical modules is higher.

[0003] Under the existing technical conditions, a traditional squirrel cage is used to fix the optical modules in a high and low temperature test environment. The utility model patent "Optical module test equipment" with the announcement number CN214149756U discloses this kind of integrated optical module test equipment with a squirrel cage. On a heating platform, multiple optical modules can be accommodated for preheating. On the test station connected to the test signal assembly, the optical modules to be tested are fixed by the squirrel cage and the heat conducting piece. The middle connecting plane is coupled by heat conducting glue. In this solution, the size of the squirrel cage is fixed, and the installation position is also fixed. Only the squirrel cage can be installed on the test station. The optical film block to be tested needs to be removed from the heating platform and installed on the squirrel cage. In a high temperature test environment, the test operator needs to be careful to avoid scratching the optical module shell.

[0004] The utility model "Optical module point temperature test tool" with the announcement number CN222231885U discloses a test squirrel cage made of a semi-metal cage. In order to prevent the optical module from scratching the surface of the optical module when it is inserted into the metal cage, the technical solution adopts a squirrel cage structure with a fixed metal base and a movable non-metal upper cover. The material hardness of the base is lower than that of the optical module structure, and the material hardness of the movable upper cover is lower than that of the optical module structure. In this way, good heat conduction of the base is achieved, and the surface of the optical module is prevented from being scratched, thereby improving the yield.

[0005] In the high temperature test environment technical scheme of adopting the traditional heat flow meter, the optical module test squirrel cage needs to be fixed in the test station and placed in the heat flow meter as a whole, and the optical module plugging operation is completed by the test operator in the heat flow meter high temperature box. The test station adopting the ceramic heating device has the advantages of direct contact heat conduction, uniform heat field, fast temperature regulation speed, small temperature difference error and supporting dry burning. The utility model discloses a scratch-proof device for improving the test system according to the advantages of the ceramic heating device. Utility model content
