[0026] like Figure 1 and Figure 2 As shown, a female end shielding assembly includes an outer shielding member 100, an inner shielding member 200, an insulator 300 and a contact assembly 400, wherein the contact assembly 400 is installed in the insulator 300, the right end of the insulator 300 is installed in the inner shielding member 200, the left end of the insulator 300 is installed in the outer shielding member 100, and the left end of the inner shielding member 200 is plugged into the inner cavity of the right end of the outer shielding member 100, as shown in FIG. Figure 3 Shown and Figure 4As shown, the left end of the inner shielding member 200 is an elliptical cavity, and the right end of the outer shielding member 100 is an elliptical cavity matching the left end of the inner shielding member. The existing female end shielding member has a rectangular structure in the nesting area of ​​the outer shielding member 100 and the inner shielding member 200. The characteristic impedance represents the transient impedance felt at any position when the signal is transmitted on a uniform transmission line, that is, the instantaneous ratio of the voltage to the current on the transmission line. It is related to the characteristics of the filling dielectric material and the lateral dimensions of the signal line (line width, line thickness, thickness of the dielectric material), but has nothing to do with the length. Therefore, when other conditions remain unchanged, The smaller the area, the smaller the capacitance, and the impedance rises to reach the impedance value required by the system. The insertion loss and return loss indicators of the system are optimized, which is actually an impedance matching problem. Therefore, the smaller the impedance fluctuation, the better the transmission performance of the system (reflection, loss and other indicators). Under the same plug-in environment, the elliptical area is smaller than the rectangular area. Therefore, the fitting area of ​​the outer shielding component 100 and the inner shielding component 200 is set to an elliptical cavity. When the outer shielding component 100 and the inner shielding component 200 are installed, the impedance of the shielding component is better, and the insertion loss, crosstalk, etc. are also better.

[0027] In this embodiment, if Figure 3 As shown, the upper, lower, left and right side walls of the left end of the outer shielding member 100 are all provided with strip holes 103 extending left and right, and the right side wall of the strip hole 103 is provided with a spring piece 102 extending leftward. When not affected by external force, the claw of the spring piece 102 protrudes from the corresponding strip hole 103, and the left end of the insulator 300 is provided with an annular groove 303 corresponding to the claw of the spring piece 102. In actual use, when the male base and the female base 10 are plugged in, the spring piece 102 will be compressed, thereby causing the spring piece 102 to generate an elastic restoring force, and the spring piece 102 is always in contact with the shielding member of the male base under the action of the elastic restoring force, thereby ensuring the shielding performance of the connector, and after the spring piece 102 is compressed, the claw of the spring piece 102 is located in the annular groove 303, thereby reserving space for the deformation of the spring piece 102.

[0028] In this embodiment, if Figure 3 As shown, the upper side wall and the lower side wall of the left end portion of the outer shielding member 100 are each provided with two spaced apart strip holes 103, the strip holes 103 extend to the left side, and the space between the left end surface of the strip hole 103 and the claw portion of the corresponding spring piece 102 forms an observation window 104, through which the assembly status of the insulator 300 and the outer shielding member 100 can be checked, thereby facilitating the assembly of the insulator 300 and the outer shielding member 100.

[0029] In this embodiment, if Figure 3As shown, the left end portion of the outer shielding member 100 is also provided with an inwardly protruding anti-fool protrusion 105, and the left end portion of the shielding component is opened and closed with an anti-fool protrusion 105 corresponding to the anti-fool protrusion 105. The anti-fool protrusion 105 is stuck in the anti-fool protrusion 301. Through the anti-fool protrusion 105 and the anti-fool protrusion 301, the shielding component can be prevented from being installed incorrectly or offset, thereby ensuring the assembly reliability of the insulator 300 and the outer shielding member 100.

[0030] In this embodiment, if Figure 4 As shown, a positioning notch 202 is provided on the left end face of the upper surface of the inner shielding member 200, and a positioning protrusion 302 corresponding to the positioning notch 202 is provided on the shielding member, and the positioning protrusion 302 abuts against the positioning notch 202. The abutment between the positioning protrusion 302 and the positioning notch 202 ensures the positioning performance of the inner shielding member 200 and the insulator 300, so that the elastic undercut 101 can smoothly enter the corresponding stop hole 201.

[0031] In this embodiment, if Figure 5 As shown, a pair of T-shaped through holes 304 are provided in the middle of the insulator 300, which pass through the two T-shaped through holes 304, and a positioning protrusion 302 is located between the two T-shaped through holes 304. The large end of the T-shaped through hole 304 is located at the right end, and a guiding slope is provided at the junction of the large end and the small end of the T-shaped through hole 304. An elastic stop buckle 401 protruding outward is provided on the contact component 400. In this embodiment, a hole is provided on the contact component 400, and then the elastic stop buckle is installed on the wall of the hole. When the elastic stop buckle 401 is pressed, the elastic stop buckle 401 can be compressed in the hole, thereby facilitating the axial insertion of the contact component 400. When the contact component After 400 is installed, the elastic stop buckle 401 is located in the large end of the T-shaped through hole 304. The contact component 400 can be well observed through the T-shaped through hole 304, which facilitates the installation of the contact component 400 and the insulator 300. During the installation process of the contact component 400 and the insulator 300, the front end of the contact component 400 is inserted from the socket of the insulator 300. When the contact component 400 contacts the guide bevel, the guide bevel can guide the contact component 400 into the socket of the insulator 300. The guide bevel can also reduce the possibility of the contact component 400 scratching the socket mouth, thereby avoiding abnormalities of the socket mouth.
