[0059] The technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0060] In the following detailed description, reference is made to the accompanying drawings that form a part of this specification, in which specific embodiments in which the present application can be implemented are shown by way of example. With respect to the accompanying drawings, directional terms such as "top", "bottom", "inside", "outside", "up", "down", "front", "back" and the like are used with reference to the directions of the accompanying drawings described. Since the components of the embodiments of the present application can be placed in many different directions, the directional terms are only used for illustration and are not intended to be limiting. It should be understood that other embodiments may be used and that structural or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be understood as limiting, and the present application is defined by the appended claims.

[0061] like Figure 1As shown, the present application proposes a shielding component 10 for an electrical connector. The shielding component 10 generally includes a first shielding sheet 1 in the shape of an elongated strip, a second shielding sheet 2 in the shape of an elongated strip, and at least one first elastic sheet 1a and at least one second elastic sheet 2a. In this article, the "elongated strip" shielding sheet actually means that the length of the shielding sheet is longer than its width, and its thickness is relatively thin and has a sheet-like structure. For example, the first shielding sheet 1 or the second shielding sheet 2 may have a roughly rectangular shape, but may not be an exact rectangle.

[0062] Each of the first shielding sheet 1 and the second shielding sheet 2 may have first and second long sides opposite to each other and first and second short sides opposite to each other, and the first shielding sheet 1 and the second shielding sheet 2 are arranged parallel to each other to be spaced apart by a distance D1. Preferably, the distance D1 may be in the range of 0.15 mm to 0.4 mm.

[0063] The first elastic piece 1a can extend from the first shielding sheet 1 in a direction away from the second shielding sheet 2, and the second elastic piece 2a can extend from the second shielding sheet 2 in a direction away from the first shielding sheet 1. In general, the first shielding sheet 1 and the structure thereon (e.g., the first elastic piece 1a) and the second shielding sheet 2 and the structure thereon (e.g., the second elastic piece 2a) have substantially similar structures, but are arranged in a mirror image to each other.

[0064] The shielding component 10 may further include at least one connecting piece 3. The connecting piece 3 may be connected to the first long side of the first shielding piece 1 and the first long side of the second shielding piece 2, in other words, connected between the first long side of the first shielding piece 1 and the first long side of the second shielding piece 2, thereby connecting the first shielding piece 1 and the second shielding piece 2 together.

[0065] Accordingly, the shielding member has a simple structure and is easy to manufacture.

[0066] In an advantageous embodiment, the shielding component 10 may be integrally formed. For example, the first shielding sheet 1, the second shielding sheet 2, the connecting sheet 3, and the first elastic sheet 1a and the second elastic sheet 2a of the shielding component 10 may be integrally formed by stamping. In particular, a sheet having a specific shape may be formed at one time by stamping a sheet of material (e.g., a metal sheet), and then bent to finally form a Figure 1 Specifically, after the sheet material is formed into a specific shape by stamping, the two ends of the connecting sheet 3 are connected to and located between the first long side of the first shielding sheet 1 and the first long side of the second shielding sheet 2, and the connecting sheet 3 is bent so that the first shielding sheet 1 and the second shielding sheet 2 are arranged parallel to each other to form the shielding component 10.

[0067] In particular, in such an embodiment, in combination with Figures 1 to 3As shown, the first shielding sheet 1 may include at least one first window H1 (two are shown in the figure), and each first spring sheet 1a is located within the range of a corresponding first window H1. Similarly, the second shielding sheet 2 may also include at least one second window H2, and each second spring sheet 2a is located within the range of a corresponding second window H2. Further, the first spring sheet 1a and the second spring sheet 2a are formed by stamping and the first window H1 and the second window H2 are formed around the first spring sheet 1a and the second spring sheet 2a respectively at the same time. In other words, the first spring sheet 1a and the second spring sheet 2a can be obtained by stamping the first window H1 and the second window H2 on the plane of the first shielding sheet 1 and the second shielding sheet 2, and the size and size of the first window H1 and the second window H2 can be adjusted according to the needs to solve the matching of crosstalk and SI value.

[0068] Accordingly, the shielding component can be manufactured more conveniently.

[0069] In an advantageous embodiment, the shielding component 10 may further include at least one first stopper 1b, which is disposed on a surface of the first shielding sheet 1 opposite to the second shielding sheet 2. Similarly, the shielding component 10 may further include at least one second stopper 2b, which is disposed on a surface of the second shielding sheet 2 opposite to the first shielding sheet 1.

[0070] By providing corresponding stop blocks on the outer sides of the two shielding sheets of the shielding component 10, the corresponding spring sheets will not bend and deform too much when being compressed inward by the components to be contacted (e.g., the side walls of the U-shaped shielding sheets of the docking connector described in detail below), because the components to be contacted will be stopped by the stop blocks when they are bent and deformed to a certain extent (e.g., flush with the highest protrusion of the stop blocks). This can effectively prevent the spring sheets from forming a simply supported beam with another spring sheet when they are bent and deformed to the limit, thereby increasing the insertion and extraction force.

[0071] In an advantageous embodiment, the connecting piece 3 may have an arched shape. Such an arched shape may be naturally formed during the bending process of the sheet mentioned above. Of course, the specific shape of the connecting piece of the present application is not limited thereto, for example, it may have a boss shape, or may even be flat.

[0072] In an advantageous embodiment, the shielding component 10 may include a plurality of connecting pieces 3 spaced apart from each other in the length direction of the shielding component 10 (the length direction is parallel to the extension direction of the long side of the first shielding piece 1 or the second shielding piece 2), and the length of the connecting piece 3 in the length direction may be greater than or equal to 0.15 mm. Figure 2 Best shown and referenced Figure 6 As shown, the elongated shielding member 10 has first ends (ie, Figure 2The left end shown) and the second end (i.e., Figure 2 The shielding component 10 is shown at the right end, wherein when the shielding component 10 is mounted on the transmission sheet of the electrical connector, the second end is closer to the transmission sheet housing, and the first end is farther away from the transmission sheet housing. In particular, the shielding component 10 may include two connecting pieces 3 spaced apart from each other in the length direction, wherein a shorter connecting piece 3 is close to the first end and is at a distance L3 from the first end, and mainly serves to connect with the upper shielding sheet or the lower shielding sheet to be described in detail later, that is, the solder joint may be located thereon, and the length of the shorter connecting piece 3 is L1, while the other longer connecting piece 3 is arranged in the middle part to mainly serve as a connecting support, and is at a distance L4 from the shorter connecting piece 3 in the length direction, and the length of the longer connecting piece 3 is L2. In particular, L1 may be in the range of 0.15 mm to 3 mm, L2 may be in the range of 0.15 mm to 3 mm, L3 may be in the range of 0.15 mm to 1.5 mm, and L4 may be in the range of 0.5 mm to 3.5 mm.

[0073] like Figure 3 and Figure 4 As best shown, the shielding component 10 may also include a long strip of sheet metal 4. The sheet metal 4 may have a first long side and a second long side opposite to each other and a first short side and a second short side opposite to each other and have a first flat surface S1 facing the first shielding sheet 1 and a second flat surface S2 facing the second shielding sheet 2. The sheet metal 4 may be fixed between the first shielding sheet 1 and the second shielding sheet 2 to cover the first window H1 and the second window H2. Furthermore, the sheet metal 4 may completely cover and enclose the first window H1 and the second window H2.

[0074] Accordingly, the shielding component 10 can have a better shielding effect.

[0075] In an advantageous embodiment, the sheet metal sheet 4 can be fixed to the first shielding sheet 1 and / or the second shielding sheet 2 by laser welding, and the welding point P formed by laser welding can be located between the first flat surface S1 and the first shielding sheet 1 and / or between the second flat surface S2 and the second shielding sheet 2. Figure 4 In FIG. 1 , the positions of six welding points P are exemplarily shown on one side.

[0076] In particular, the distance D2 between the first flat surface S1 and the second flat surface S2 may be greater than or equal to 0.1 mm, but it may not be greater than the distance D1.

[0077] In a preferred embodiment, the sheet metal sheet 4 may include a plurality of protrusions 41 extending from the first long side of the sheet metal sheet 4, and each connecting sheet 3 is located between two adjacent protrusions 41. The protrusions 41 extending therefrom may be used to connect with an upper shielding sheet or a lower shielding sheet described in detail below. Similarly, the sheet metal sheet 4 may also include a plurality of protrusions extending in the opposite direction from the second long side of the sheet metal sheet 4, for connection with a lower shielding sheet described in detail below, or the sheet metal sheet 4 may include a plurality of protrusions extending from both the first long side and the second long side of the sheet metal sheet 4, for connection with an upper shielding sheet and a lower shielding sheet described in detail below, respectively.

[0078] Combination Figures 5 to 7 As shown, the present application also proposes an electrical connector 1000. The electrical connector 1000 may include a plurality of transmission sheets 100. Each transmission sheet 100 generally includes a transmission sheet housing 20, a signal terminal row 30, an upper shielding sheet 40 and a lower shielding sheet 50, two side shielding sheets 60, and at least one shielding component 10 described above.

[0079] The signal terminal row 30 is held in the transmission sheet housing 20 and may include a plurality of differential signal terminal pairs 301 arranged adjacent to each other. Each differential signal terminal pair 301 is composed of two signal terminals 301a arranged adjacent to each other and includes a plug-in portion extending outside the transmission sheet housing 20 for mating with a corresponding signal terminal pair 2001 of a mating connector 2000.

[0080] The upper shielding sheet 40 and the lower shielding sheet 50 may be fixed to the transmission sheet housing 20 and located at opposite sides of the signal terminal row 30. Two side shielding sheets 60 may be arranged side by side in parallel with each other and connected between the upper shielding sheet 40 and the lower shielding sheet 50 to enclose a terminal accommodation space A together with the upper shielding sheet 40 and the lower shielding sheet 50. The signal terminal row 30 is located in the terminal accommodation space A.

[0081] The shielding member 10 may be disposed in the terminal accommodation space A, connected between the upper shielding sheet 40 and the lower shielding sheet 50, and arranged parallel to each other with the two side shielding sheets 60, so that the terminal accommodation space A is divided into a plurality of accommodation sub-spaces A1. Each differential signal terminal pair 301 is located in a corresponding one of the accommodation sub-spaces A1.

[0082] In an advantageous embodiment, the shielding component 10 may be fixed together with the upper shielding sheet 40 and the lower shielding sheet 50 by laser welding.

[0083] In an advantageous embodiment, the docking connector 2000 may further include a plurality of U-shaped shielding sheets 2002, each of which surrounds the corresponding signal terminal pair 2001 of the docking connector 2000 and includes two side walls 2002a parallel to each other and a bottom wall 2002b connected between one side edge of the two side walls 2002a, and an open opening formed by the other side edge of the two parallel side walls 2002a (i.e., the open opening of the U-shaped shielding sheet 2002) is opposite to the bottom wall 2002b. When the electrical connector 1000 and the docking connector 2000 are plugged together, each U-shaped shielding sheet 2002 is inserted into the corresponding accommodating subspace A1, and the first elastic sheet 1a and / or the second elastic sheet 2a abut against the corresponding side wall 2002a, thereby forming a common ground. Further, the U-shaped shielding sheet 2002 is located in a containing sub-space A1 surrounded by an upper shielding sheet 40, a lower shielding sheet 50 and two shielding components 10 opposite to each other on both sides, or in a containing sub-space A1 surrounded by an upper shielding sheet 40, a lower shielding sheet 50 and a shielding component 10 and a side shielding sheet 60, and the bottom wall 2002b is connected to the lower shielding sheet 50 or the upper shielding sheet 40, and the corresponding opening portion of the bottom wall 2002b is shielded by the lower shielding sheet 50 or the upper shielding sheet 40.

[0084] Accordingly, a more closed cavity structure can be formed around each differential signal terminal pair, thereby reducing the crosstalk effect between the signal terminals.

For those skilled in the art, the present application may have various modifications and variations.
