A radio frequency coaxial connector, including a cover, the upper and lower parts of the cover are provided with a touch part setting hole, the touch part setting hole is fixed and inserted with a touch part, the touch part includes an external electric conductor, the external electric conductor The inner thread of the inner thread is fixed by the conductor and the insulator to fix the inner conductor in the outer conductor. The front end of the touch piece is developed to be plugged with a compatible touch piece, and the rear end of the touch piece is fixedly provided with a sandwich layer A glass sealing member made of glass that cooperates with the outer electrical conductor to form a shielded cavity. A connecting conductor is installed under the glass sealing member. The inner end of the connecting conductor connects with the inner electrical conductor, and the toe of the connecting conductor Used to connect with the power circuit. The back-end development of the contact part of this product is equipped with a glass sealing member that cooperates with the external electrical conductor to form a sealed cavity. The connecting electrical conductor set inside the glass sealing member connects the internal electrical conductor to the power circuit. A bottom-shielded cavity is formed inside the conductor, which maintains excellent magnetic shielding material and airtightness, and reasonably prevents the data signals transmitted in the touch parts from being subjected to external interference signals.
