The above-mentioned existing technical solution has the following shortcomings: this technical solution realizes stable pressure contact of the inner conductor by installing a high-precision elastic part on the inner end of the probe, but the millimeter wave connector and the connecting sleeve are threadedly connected, which is prone to rotation or loosening after long-term use, affecting the subsequent work and making it difficult to proceed smoothly. At the same time, when the probe is not in use, dust in the air is easy to adhere to its upper end, which will have a certain adverse effect on data transmission. Therefore, we need to design a millimeter wave connector with a dustproof structure to solve the above-mentioned problems. Utility Model Content
