For those of ordinary skill in the art, specific meanings of the preceding terms in the present disclosure may be understood based on specific situations.

[0045] An embodiment provides a conductive sheet structure 1 which can be in elastic contact with a grounding terminal 3 and thus can reduce the probability of poor contact of a high-speed connector.

[0046] As shown in FIGS. 1 to 8, the conductive sheet structure 1 includes a conductive sheet 11 and a plurality of elastic arms 12 disposed on the conductive sheet 11.

[0047] The elastic arms 12 are arranged on the conductive sheet 11 with spacings. Each elastic arm 12 includes a connecting section 121, a tilt section 122 and a contact section 123 which are connected in sequence. The connecting section 121 is fixedly connected to the conductive sheet 11. The tilt section 122 is tilted relative to the conductive sheet 11. The tilt angle between the tilt section 122 and the conductive sheet 11 is variable. That is, the distance from the end of the tilt section 122 closer to the contact section 123 to the conductive sheet 11 can be varied. The contact section 123 is used for contacting with a grounding terminal 3 on a high-speed connector.

[0048] When the contact section 123 is in contact with the grounding terminal 3, the elastic arm 12 is in a state of compression, that is, the distance between the end of the tilt section 122 closer to the contact section 123 and the conductive sheet 11 is smaller than the original distance (that is, the distance between the end of the tilt section 122 closer to the contact section 123 and the conductive sheet 11 when the contact section 123 is not in contact with the grounding terminal 3). In this manner, when the grounding terminal 3 has a different height, only the extent to which the elastic arm 12 is compressed is affected, and the contact section 123 is still able to be in contact with the grounding terminal 3.

[0049] According to the conductive sheet structure 1 provided by this embodiment, the elastic arms 12 are arranged on the conductive sheet 11, and the elastic arms 12 can be elastically deformed. In this manner, the conductive sheet 11 can be in elastic contact with the grounding terminal 3 through each elastic arm 12, so even if the top surface of the grounding terminal 3 is uneven, the contact section 123 of each elastic arm 12 can be in effective contact with the grounding terminal 3 due to the existence of the tilt section 122. Thus, the probability of poor contact of the high-speed connector is reduced, and signal transmission of communication device is guaranteed.

[0050] Optionally, the conductive sheet 11 may have various structures, and this embodiment provides two types of conductive sheets 11 as described below.

[0051] In the structure of one type of conductive sheet 11, as shown in FIGS. 1 to 7, the conductive sheet 11 is provided with a plurality of openings 111, and at least one elastic arm 12 is fixed in each opening 111. In the drawings, FIG. 1 is a schematic view showing one elastic arm 12 disposed in each opening 111, and FIGS. 2 to 7 are schematic views showing two elastic arms 12 disposed in each opening 111. Optionally, as shown in FIG. 1, when one elastic arm 12 is disposed in each opening 111, the elastic arm 12 may be located on any edge of each opening 111, or the orientations of the elastic arms 12 disposed on the conductive sheet 11 may be the same or different. When two or more elastic arms 12 are disposed in each opening 111, two or more elastic arms 12 located in the same opening 111 can be in contact with the same grounding terminal 3, ensuring that the grounding terminal 3 can be in effective contact with the conductive sheet 11.

[0052] Further, each opening 111 in the conductive sheet 11 may be a rectangle opening, and when two elastic arms 12 are disposed in each opening 111, as shown in FIGS. 2 to 7, each of the two elastic arms 12 may be fixed to a respective one of the opposite inner walls of each opening 111, and the two elastic arms 12 can be in contact with the same grounding terminal 3. When two elastic arms 12 are disposed in each opening 111, it is possible to make the conductive sheet structure 1 lighter and facilitate the mounting of the conductive sheet structure 1 while ensuring that the conductive sheet 11 is in effective contact with the grounding terminal 3.

[0053] Optionally, when two elastic arms 12 are disposed in each opening 111, as shown in FIGS. 3, 4 and 6, two elastic arms 12 located in the same opening 111 may be staggered, or as shown in FIG. 5 or FIG. 7, two elastic arms 12 located in the same opening 111 may be symmetrically arranged. When two elastic arms 12 are staggered in one opening 111, as shown in the first opening 111 from the left of FIG. 3, the elastic arm 12 fixed to the left inner wall of the opening 111 may be located below the elastic arm 12 fixed to the right inner wall of the opening 111, or as shown in the second opening 111 from the left of FIG. 3, the elastic arm 12 fixed to the left inner wall of the opening 111 may be located above the elastic arm 12 fixed to the right inner wall of the opening 111, which is not limited in this embodiment.

[0054] Optionally, the openings 111 are arranged in an array on the conductive sheet 11. For example, the openings 111 may be arranged in a plurality of rows and columns on the conductive sheet 11 to apply to high-speed connectors having different structures. Exemplarily, as shown in FIG. 3 or FIG. 5, a plurality of openings 111 are arranged in sequence along the length direction of the conductive sheet 11. In this case, it can be considered that the openings 111 are arranged in one row and a plurality of columns, and each opening 111 can correspond to one grounding terminal 3. For example, the openings 111 may be in one row and four columns. As another example, as shown in FIGS. 6 and 7, the openings 111 are arranged in two rows and a plurality of columns on the conductive sheet 11, and the openings 111 located in the same column can correspond to the same grounding terminal 3. That is, the elastic arms 12 located in the openings 111 in the same column can be in contact with the same grounding terminal 3. For example, the openings 111 may be in two rows and seven columns. Such arrangement mode can be used for high-speed connectors having long grounding terminals.

[0055] In the structure of another type of of the conductive sheet 11, as shown in FIG. 8, the conductive sheet 11 is strip-shaped, the conductive sheet 11 is not provided with openings, and the elastic arms 12 include a plurality of first elastic arms 124 and a plurality of second elastic arms 125. The first elastic arms 124 are arranged on the edge of one side of the conductive sheet 11 with spacings, the second elastic arms 125 are arranged on the edge of the other side of the conductive sheet 11 with spacings, and each second elastic arm 125 corresponds to a respective first elastic arm 124 and is connectable to the same grounding terminal 3 as the respective first elastic arm 124. Exemplarily, the first elastic arms 124 and the second elastic arms 125 may be staggered on two sides of the conductive sheet 11, and the orientations of a first elastic arm 124 and a second elastic arm 125 corresponding to each other are opposite.

[0056] A conductive sheet structure 1 having either of the preceding two structures can be in stable and effective contact with the grounding terminal 3. Such conductive sheet structure 1 is simple in structure, convenient to manufacture and low in cost.

[0057] Optionally, as shown in FIG. 4, the surface, which is contacted with the grounding terminal 3, of the contact section 123 of the elastic arm 12 is flat so that the area, which is contacted with the grounding terminal 3, of the elastic arm 12 can be relatively large, further ensuring effective contact between the elastic arm 12 and the grounding terminal 3. Exemplarily, as shown in FIG. 4, the contact section 123 of the elastic arm 12 is sheet-shaped and parallel to the conductive sheet 11.

[0058] Another embodiment provides a high-speed connector. As shown in FIGS. 9 to 11, the high-speed connector includes a housing 2, a grounding terminal 3 and a signal terminal 4 fixed to the housing 2, and the preceding conductive sheet structure 1. The conductive sheet structure 1 is fixed to the housing 2. The contact section 123 in the elastic arm 12 abuts against the grounding terminal 3. Grounding terminals 3 and signal terminals 4 are arranged in sequence with spacings, and two signal terminals 4 are arranged between each two adjacent grounding terminals 3.

[0059] Further, the high-speed connector may include one or more conductive sheet structures 1, and when the high-speed connector includes a plurality of conductive sheet structures 1, a part of the conductive sheet structures 1 is fixed to an upper wall 21 of the housing 2, and the other part of the conductive sheet structures 1 is fixed to a side wall 22 of the housing 2. Exemplarily, as shown in FIGS. 9 and 10, the high-speed connector may include two conductive sheet structures 1, one of which is located on the upper wall 21 of the housing 2 and the other of which is located on the side wall 22, specifically the front side wall, of the housing 2.

[0060] Optionally, at least one of the upper wall 21 or the side wall 22 of the housing 2 is provided with a fixing groove 23 in which the conductive sheet structure 1 is welded or glued to prevent separation of the conductive sheet structure 1 from the housing 2.

[0061] In an exemplary embodiment, when the high-speed connector includes one conductive sheet structure 1, the upper wall 21 or the side wall 22 of the housing 2 may be provided with one fixing groove 23 in which the one conductive sheet structure 1 is welded or glued. In an exemplary embodiment, when the high-speed connector includes a plurality of conductive sheet structures 1, a part of the conductive sheet structures 1 is disposed on an upper wall 21 of the housing 2 and the other part of the conductive sheet structures 1 is disposed on a side wall 22 of the housing 2, only the upper wall 21 of the housing 2 may be provided with one or more fixing grooves 23 in which a respective conductive sheet structure disposed on the upper wall 21 of the housing 2 is welded or glued, or only the side wall 22 of the housing 2 may be provided with one or more fixing grooves 23 in which a respective conductive sheet structure disposed on the side wall 22 of the housing 2 is welded or glued, or the upper wall 21 and the side wall 22 of the housing 2 are provided with fixing grooves in each of which a respective one of the plurality of conductive sheet structures is welded or glued.

[0062] FIG. 10 is a schematic view showing the side wall 22 of the housing 2 having the fixing groove 23. When a fixing groove 23 is disposed on the upper wall 21 of the housing 2, reference can be made to the structural arrangement in which the side wall 22 has a fixing groove 23.

Various modifications and variations made without departing from the spirit and scope of the present disclosure fall within the scope of the present disclosure. The scope of the present disclosure is defined by the appended claims and their equivalents.
