[0030] like Figure 6 and Figure 7 As shown, a connector includes a female end base 10, a shielding assembly is installed in the female end base 10, a locking tongue 14 is arranged on the upper surface of the female end base 10, and a positioning member 20 is also installed on the upper surface of the female end base 10 to prevent the locking tongue 14 from pressing down. In this embodiment, as Figure 1 , Figure 2 As shown, the shielding assembly includes an outer shielding member 100, an inner shielding member 200, an insulator 300 and a contact assembly 400. 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. Figure 3 and Figure 4 As shown, the upper surface and the lower surface of the left end of the inner shielding member 200 are both provided with a stop hole 201, and the upper surface and the lower surface of the right end of the outer shielding member 100 are provided with an elastic buckle 101 corresponding to the stop hole 201, the elastic buckle 101 is convex inward, and the elastic buckle 101 is stuck in the corresponding stop hole 201. When installing, the contact assembly 400 is installed in the insulator 300, and then the left end of the insulator 300 is inserted from the right end of the outer shielding member 100. After the insulator 300 is installed in the outer shielding member 100, the left end of the inner shielding member 200 is then plugged into the inner cavity of the right end of the outer shielding member 100. In this embodiment, as shown in FIG. Figure 3 As shown, square holes are provided on the upper and lower surfaces of the right end portion of the outer shielding member 100, and an elastic undercut 101 extending to the left is provided on the right side wall of the square hole. When the elastic undercut 101 contacts the inner shielding member 200, the elastic undercut 101 is squeezed, thereby generating elastic deformation. When the elastic undercut 101 enters the stop hole 201, the elastic undercut 101 enters the stop hole 201 under the action of the elastic restoring force, and the left end face of the elastic undercut 101 abuts against the right end face of the stop hole 201, thereby realizing the assembly of the inner shielding member 200 and the outer shielding member 100, and the assembled inner shielding member 200 and the outer shielding member 100 cannot be separated, thereby eliminating the laser welding process, reducing the assembly process, and making the assembly of the inner shielding member 200 and the outer shielding member 100 simple and convenient.

[0031] In this embodiment, if Figure 3 As shown, there are four elastic undercuts 101 and four stop holes 201. The upper surface of the outer shielding component 100 has two elastic undercuts 101, and the lower surface of the outer shielding component 100 has two elastic undercuts 101. The four elastic undercuts 101 are all on the same vertical plane. The four stop holes 201 are fastened together to ensure the assembly stability of the inner shielding component 200 and the outer shielding component 100.

[0032] 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.

[0033] 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.

[0034] In this embodiment, if Figure 5 As 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.

[0035] In this embodiment, if Figure 4 and Figure 5 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.

[0036] In this embodiment, if Figure 2 As shown, the female end base 10 is provided with an installation cavity 11, and the shielding assembly is installed in the installation cavity 11. A raised limiting protrusion 106 is provided on the outer shielding member 100 of the shielding assembly, and a limiting end face 2612 abutting against the limiting protrusion 106 is provided in the installation cavity 11.

When the locking block 13 is installed, the end of the locking block 13 is stuck in the limiting recess of the inner shielding member 200, thereby preventing the shielding assembly from axially withdrawing, and the abutment between the limiting protrusion 106 and the limiting end face 2612 prevents the shielding assembly from axially moving forward, thereby preventing the shielding assembly from axially moving relative to the female end base 10, thereby ensuring the reliability of the assembly of the shielding assembly and the female end base 10.

[0037] In this embodiment, if Figure 8As shown, the positioning member 20 includes a positioning block 25, a limiting block 22 extending to the left is arranged on the left end surface of the positioning block 25, a wedge-shaped surface 23 is arranged on the left end of the limiting block 22, and two elastic arms 21 are also arranged on the left end surface of the positioning block 25, the limiting block 22 is located between the two elastic arms 21, and a buckle 24 protruding outward is arranged on the outer side of the left end of the elastic arm 21, and two relatively arranged limiting walls 17 are arranged on the upper surface of the female end base 10. In this embodiment, the limiting wall 17 is a "7"-shaped structure. When the limiting wall 17 is installed, an installation groove for installing the positioning member 20 is formed between the two limiting walls 17, and a first lock hole 15 and a second lock hole 16 are opened on the limiting wall. The first lock hole 15 is located at the bottom of the female end base 10. On the right side of the second locking hole 16, when the female base 10 is locked with the male base, the buckle 24 is located in the second locking hole 16, and the wedge-shaped surface 23 is in contact with the lower surface of the locking tongue 14, and when the female base 10 is not plugged into the male base, the buckle 24 is located in the first locking hole 15. At this time, the wedge-shaped surface 23 is located in front of the locking tongue 14. The locking tongue 14 can be pressed at this time, and the positioning member 20 is also prevented from being separated from the female base 10. When the male connector and the female connector need to be separated, the buckle 24 is withdrawn from the second locking hole 16 into the first locking hole 15, and then the locking tongue 14 is pressed to unlock the male connector and the female connector, and then the male connector and the female connector can be pulled apart.
