[0002] In today's electronic communications, such as voice transmission, data transmission, and image transmission, coaxial high-speed cables are required to transmit data, and coaxial connectors are set at both ends of the coaxial high-speed cables. Coaxial connectors can be used to connect circuit boards, circuit boards and modules, and modules and modules.

[0003] At present, the terminal assembly in the coaxial connector generally includes an outer conductor, an inner insulator and an inner conductor arranged in sequence from the outside to the inside, wherein the outer conductor is generally produced by mechanical processing or die-casting, which has high processing costs and wastes working hours. More and more outer conductors are formed by stamping of metal sheets, but when stamping the outer conductor to process the card slot that cooperates with the TPA part, it will inevitably form a rounded structure at both ends of the card slot, which will lead to poor matching effect and stability when the card slot cooperates with the secondary lock assembly (TPA part) of the connector. In addition, the existing outer conductor is used to prevent the terminal assembly from continuing to be inserted into the sheath through the puncture structure arranged on the outside, that is, to achieve the front stop of the terminal assembly, but the puncture structure protruding outward by stamping will cause a gap between the inside and outside of the outer conductor, affecting the shielding effect of the outer conductor and causing attenuation of the transmitted signal.
