[0026] Such as Figures 1 to 5As shown in the figure, the present utility model discloses a highly protective connector socket, including a housing 1. At the front end center of the housing 1, there is a plug-in cavity 100. Inside the plug-in cavity 100, there are a signal connection part, two terminal connection parts, a first shielding part 2, and a second shielding part 3. The two terminal connection parts have the same structure and are symmetrically arranged. The signal connection part is located between the two terminal connection parts. The signal connection part and the terminal connection parts penetrate through the front and rear end faces of the plug-in cavity 100. The first shielding part 2 is sleeved on the outer wall bottom of the terminal connection part protruding from the front end face of the plug-in cavity 100. The edge of the first shielding part 2 has a set of first hooks 201. The set of first hooks 201 is inserted from the front end face of the plug-in cavity 100 and is engaged therewith. The second shielding part 3 is located between the outer walls of the two terminal connection parts protruding from the rear end face of the plug-in cavity 100. The edge of the second shielding part 3 has a set of second hooks 301. The second hooks 301 are inserted from the rear end face of the plug-in cavity 100 and are engaged therewith. On both sides of the second shielding part 3 adjacent to the first shielding part 2, there is a set of elastic contacts 302 evenly distributed. The set of elastic contacts 302 are respectively abutted against the side walls of the two first shielding parts 2, so that the second shielding part 3 is connected to the two first shielding parts 2 to form a continuous shielding layer.

[0027] In this solution, the first shielding part 2 is arranged on the outer wall of the terminal connection part to play a left and right shielding role. The second shielding part 3 is arranged between the two first shielding parts 2. And both sides of the second shielding part 3 are connected to the first shielding part 2 through the elastic contacts 302 to form a continuous and complete shielding layer structure, so as to also form a shielding effect on the middle part between the two terminal connection parts, maximizing the overall shielding protection effect and avoiding electromagnetic leakage from the middle.

[0028] Specifically, as shown in Figure 1 and Figure 2 , the housing 1 is composed of a plug-in housing 104 and a flange 105. The plug-in housing 104 is fixed on the front end face of the flange 105 and encloses to form the plug-in cavity 100. On the outer wall of the plug-in housing 104, there are necessary structures such as teeth for connecting with other components (such as a plug assembly).

[0029] The terminal connection part includes a terminal connection cavity 401, a terminal limiting bracket 402, and a male terminal 4. The terminal connection cavity 401 is fixedly arranged in the insertion cavity 100 and is a hollow cavity with openings at both ends. The terminal limiting bracket 402 is fixedly arranged at the axis of the terminal connection cavity 401 through a group of reinforcing ribs 403, and it is a frame body whose inner contour matches the outer contour of the male terminal 4. The male terminal 4 is inserted into the terminal limiting bracket 402 from the bottom opening and is limited within the terminal limiting bracket 402. For the convenience of manufacturing, the terminal connection cavity 401, the terminal limiting bracket 402, the reinforcing ribs 403 and the housing 1 are integrally formed.

[0030] The inner contour of the first shielding member 2 matches the outer contour of the terminal connection cavity 401, so as to be sleeved on the outer wall of the terminal connection cavity 401. A first card slot 101 is opened on the end face of the insertion cavity 100. After the first catch 201 is inserted into the first card slot 101, it is bent at 90° to be clamped with the end face of the insertion cavity 100.

[0031] Further, as Figures 3 - 5 shown, each first catch 201 has two hook parts 2011, and there is a first elastic piece 2012 extending outwardly obliquely between the two hook parts 2011. A first bayonet 1011 matching the first elastic piece 2012 is arranged on the inner wall of the first card slot 101, so that after the first catch 201 is inserted into the first card slot 101, the first elastic piece 2012 is clamped in the first bayonet 1011. The first elastic piece 2012 and the hook part 2011 together make the first catch 201 stably clamped with the first card slot 101, so that the first shielding member 2 is not easily separated. In the illustrated embodiment, the first catch 201 is arranged on the edges of the other three sides of the two first shielding members 2 except the adjacent sides between them, so as to improve the clamping stability of the first shielding member 2 and the insertion cavity 100.

[0032] Similarly, a second card slot 102 matching the second catch 301 is opened on the end face of the insertion cavity 100. The second catch 301 has a group of second elastic pieces 3011 extending inwardly obliquely, and a second bayonet 1021 matching the second elastic pieces 3011 is arranged in the second card slot 102, so that after the second catch 301 is inserted into the second card slot 102, the second elastic pieces 3011 are clamped in the second bayonet 1021. The second catch 301 is arranged on the edge of the side of the second shielding member 3 that is not adjacent to the first shielding member 2.

[0033] Further, a set of elastic fingers 303 are spaced on two sides of the second shielding member 3 adjacent to the first shielding member 2. The end faces of the elastic fingers 303 perpendicular to the second shielding member 3 extend, and their extended ends bend outward to form the elastic contacts 302. Such a structure can increase the width of the elastic contacts 302, so that when the second shielding member 3 is inserted, the first shielding member 2 will inwardly press the elastic contacts 302, thereby keeping the elastic contacts 302 in contact with the side wall of the first shielding member 2. A strip-shaped hole 103 through which the elastic contacts 302 can pass is formed on the end face of the insertion cavity 100 to allow the elastic fingers 303 to extend in.

[0034] The signal connection part includes a signal terminal connection cavity 601 and signal terminals 6. The signal terminals 6 are inserted into the signal terminal connection cavity 601. The signal terminal connection cavity 601 is also integrally formed with the housing 1 and penetrates the front and rear end faces of the insertion cavity 100. Since the signal terminal connection cavity 601 is located between two terminal connection cavities 401, a recess 304 for avoiding the signal terminal connection cavity 601 is provided on the second shielding member 3.

[0035] In addition, a groove is provided on the back surface of the flange 105, and a sealing ring 5 is clamped in the groove, so that after the connection cavity socket is connected to other components, the sealing ring 5 seals the back surface of the flange 105.

[0036] To facilitate the connection of the flange 105, connection holes 106 are formed at the corners of the flange 105, and metal rings are embedded in the connection holes 106.

The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
