The plug-in latching component 90 and the mating guide groove 144 cooperate to engage with the latching structure on the male connector to achieve quick plugging and secure fixing of the connector. The protective plate 93 is located on the outer side wall of the fixing part 11 and on both sides of the pressing plate 92, forming a limiting cavity with the outer casing 10 and the pressing plate 92 to further ensure the movement stability and reliability of the pressing plate 92.

[0060] During assembly, insert the insulating sleeve 22 into the zinc alloy mating sleeve 21, and mark the zinc alloy around the perimeter; insert the contact ring 216; lead out a shielded wire 40 from the main wire braid, pre-install the main wire heat shrink tubing 31 and the crimped sleeve 24; crimp the main wire to the electrical terminal 23; crimp the shielded wire 40 to the shielded terminal 50; insert the electrical terminal 23 into the plastic core and crimp the crimped sleeve 24; install the main wire (coaxial cable), shielded wire 40 and shielded terminal 50 into the plastic shell, and install the first fixing member 70 and the second fixing member 60.

[0061] During actual assembly, the crimped sleeve 24 on the outer periphery of the wiring part 213 is fitted onto the part where the wiring part 213 and the coaxial line 30 need to be connected. Pressure is applied by a special crimping device to cause the crimped sleeve 24 to undergo plastic deformation. The deformed crimped sleeve 24 tightly wraps around the wiring part 213 and the coaxial line 30, reducing the air gap between them, lowering the contact resistance, and ensuring the stability of current and signal transmission. At the same time, it can also ensure that the wiring part 213 and the coaxial line 30 always maintain a stable connection and will not loosen or fall off, further improving the practicality and reliability of the female connector of this utility model.
