Description
Technical Field

Background
In the prior art, coaxial connectors typically include a housing, an outer terminal, an insulating core, a center terminal (or inner terminal), and a cable. The outer terminal, the insulating core, the center terminal and the cable are preassembled into one electrical connection module, which is then inserted into the housing. The center terminal is inserted in the insulating core, and the insulating core is inserted in the outer terminal. The rear end of the center terminal is soldered to the conductor core of the cable, and the front end of the center terminal is used for electrical contact with the mating center terminal. The rear end of the outer terminal is fixed to the cable and electrically connected with the shielding layer of the cable.
In the related art, when soldering the rear end of the center terminal, solder, such as solder and flux, may flow to the front end along the center through hole of the center terminal, which may affect the electrical contact performance between the center terminal and the mating center terminal. In addition, in the prior art, it is difficult to ensure that the diameters of the two positioning flanges on the outer terminal are uniform, which may cause the outer terminal to tilt during the insertion, and easily cause damage to the elastic arm of the outer terminal. Furthermore, in the prior art, the external terminals may appear to shake in the housing, which may cause unstable electrical contact and may easily cause signal snap-off. Furthermore, in the prior art, there is no primary lock in the housing that can be used to lock the external terminals, which results in the possibility of movement of the external terminals before the secondary lock is latched, affecting the quality of the installation of the connector. In addition, the existing external terminal has the disadvantages of high manufacturing difficulty, high cost and large axial length.
