[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0044] This application provides a grounding plate. Specifically, the grounding plate 600 of this application embodiment is used for, for example... Figure 6 and Figure 7 The board-to-board connector 10 is shown. (As shown in the image.) Figure 6 As shown, the grounding piece 600 is approximately positioned at the middle of the board-to-board connector 10 along its length direction (X direction).
[0045] like Figure 1 As shown, the grounding plate 600 includes two plug-in portions 610 and a connecting portion 620 connecting the two plug-in portions 610. The two plug-in portions 610 are respectively disposed on both sides of the connecting portion 620 along the width direction (Y direction). Figure 2 As shown, two plug-in portions 610 are symmetrically arranged on both sides of the connecting portion 620. Each plug-in portion 610 is provided with a socket 611 and a plug arm 612, which are arranged sequentially along the length direction. Figure 8As shown, when the two board-to-board connectors 10 are engaged, the grounding plates 600 on the two board-to-board connectors 10 also engage with each other, as shown. Figure 5 As shown, the insertion arm 612 on the grounding plate 600 of one board-to-board connector 10 is inserted into the socket 611 on the grounding plate 600 of another board-to-board connector 10. Figure 8 and Figure 9 As shown, when the two board-to-board connectors 10 are engaged, one connector rotates 180 degrees relative to the other connector and then engages, so that the arm 612 of the grounding plate 600 on one connector is aligned with the socket 611 of the grounding plate 600 on the other connector.
[0046] like Figure 6 As shown, by placing the grounding piece 600 of this embodiment on the board-to-board connector 10, the grounding area of the connector can be increased, allowing for the flow of large current and adapting to scenarios with high power flow. Furthermore, as... Figure 1 As shown, the grounding piece 600 of this application includes two plug-in portions 610, combined with Figure 1 and Figure 6 As shown, two plug-in portions 610 are provided on both sides of the board-to-board connector 10. The plug-in portions 610 are provided with sockets 611 and plug arms 612 to facilitate the fastening and fixing of the two board-to-board connectors 10.
[0047] In one embodiment, such as Figure 3 As shown, the insertion portion 610 includes an arched portion 613. The arched portion 613 is used to provide the insertion port 611. Figure 1 As shown, the socket 611 is located at the top of the arched portion 613. One side of the arched portion 613 is connected to the connecting portion 620. By placing the socket 611 at the top of the arched portion 613, the height of the socket 611 can be raised, giving the insertion arm 612 sufficient space to be inserted downwards, thereby making the insertion of the insertion arm 612 and the socket 611 more secure.
[0048] like Figure 1 As shown, the socket 611 has flanges 6111 on both sides that bend inwards. Combined with... Figure 1 and Figure 5 As shown, the flange 6111 can clamp the insert arm 612 inserted into the socket 611. The outer end of the flange 6111 is connected to the edge of the socket 611, and the other end of the flange 6111 is bent into the socket 611, so that the end of the flange 6111 bent into the socket 611 is elastic and can clamp the insert arm 612.
[0049] In one embodiment, such as Figure 4As shown, the insertion arm 612 includes a first bent portion 6121, a second bent portion 6122, and a solder foot portion 6123. The first bent portion 6121 extends upward from the connecting portion 620. The second bent portion 6122 bends outward and downward from the first bent portion 6121 along the width direction (Y direction). The solder foot portion 6123 extends horizontally outward from the second bent portion 6122 along the width direction (Y direction). Here, "outward" refers to the direction away from the center of the grounding plate 600 along the Y direction. The above structure of the insertion arm 612 makes the insertion arm 612 a flexible arm that can be securely inserted into the socket 611 and cooperate with the socket 611.
[0050] like Figure 1 As shown, the grounding piece 600 also includes a protective part 630. Combined with... Figure 1 and Figure 7 The protective part 630 is used to protect the island 140 on the insulating base 100 of the board-to-board connector 10. For example... Figure 1 As shown, the protective portion 630 is disposed at one end of the grounding plate 600 along its length direction (X direction) and at the middle position of the grounding plate 600 along its width direction (Y direction). The protective portion 630 includes a third bend portion 631 and a fourth bend portion 632. The third bend portion 631 bends upward from the connecting portion 620. The fourth bend portion 632 bends forward and downward from the third bend portion 631 along its length direction (X direction). Here, "forward" refers to the direction away from the center of the grounding plate 600 along the X direction. Figure 1 and Figure 6 As shown, the third bend 631 can cover one end of the island portion 140 of the insulating base 100, thereby protecting the island portion 140. The fourth bend 632 can be embedded in the insulating base 100, thereby making the grounding piece 600 more securely fixed on the insulating base 100.
[0051] like Figure 1 As shown, the grounding piece 600 also includes a fixing part 640. The fixing part 640 is located at the other end of the grounding piece 600 along its length (X direction), that is, the end opposite to the protective part 630. The fixing part 640 is a bent arm formed by bending the connecting part 620 upwards. The grounding piece 600 and the insulating base 100 are integrally molded by injection molding. After molding, the fixing part 640 is embedded in the insulating base 100, thereby better fixing the grounding piece 600.
[0052] This application also provides a board-to-board connector 10. For example... Figure 6 As shown, one end of the board-to-board connector 10 is a male connector 10a, and the other end is a female connector 10b. Figures 8 to 9As shown, in use, two board-to-board connectors 10 are interlocked, with one connector rotating 180 degrees relative to the other for interlocking. The male connector 10a of one board-to-board connector 10 engages with the female connector 10b of the other board-to-board connector 10, and simultaneously, the female connector 10b engages with the male connector 10a of the other board-to-board connector 10, thus achieving signal transmission. In the prior art, the male and female connectors have different structures, and signal transmission is achieved by interlocking the male and female connectors. The board-to-board connector 10 of this application embodiment, with a male connector 10a at one end and a female connector 10b at the other end, is a connector with an integrated male and female connector. Interlocking two board-to-board connectors 10 of this application embodiment can replace the prior art of interlocking two male and female connectors with different structures. Only one mold is needed, reducing mold costs and the number of parts.
[0053] like Figure 6 and Figure 7 As shown, the board-to-board connector 10 of this embodiment includes the aforementioned grounding plate 600, as well as an insulating base 100, a male terminal 200, a female terminal 300, a first grounding plate 400, and a second grounding plate 500. The grounding plate 600, the male terminal 200, the female terminal 300, the first grounding plate 400, and the second grounding plate 500 are all disposed on the insulating base 100.
[0054] like Figure 7 As shown, the insulating base 100 includes a base plate 110, a male flange 120, a female flange 130, and an island portion 140. The male flange 120 is located at one end of the base plate 110, and the female flange 130 and the island portion 140 are located at the other end of the base plate 110. Here, "one end" and "the other end" refer to the two ends of the insulating base 100 along its length direction (X direction). Figure 7 As shown, both the male flange 120 and the female flange 130 are arranged around the edge of the base plate 110. The island portion 140 is located within the frame formed by the female flange 130. A female slot 101 is formed between the island portion 140 and the female flange 130. The male flange 120 and the female flange 130 are respectively provided at both ends of the insulating base 100 to facilitate the integration of the male base 10a and the female base 10b onto the board-to-board connector 10 of this embodiment. The insulating base 100 can be injection molded. When the two board-to-board connectors 10 are fastened, the male flange 120 of one board-to-board connector 10 is engaged into the female slot 101 of the other board-to-board connector 10 to complete the fastening.
[0055] like Figure 6 As shown, the male connector terminal 200 is disposed on the male connector flange 120, and the female connector terminal 300 is disposed in the female connector slot 101. When the two board-to-board connectors 10 are engaged, they are connected... Figure 8 and Figure 9As shown, the male flange 120 of one connector is inserted into the female socket 101 of another connector, and the male terminal 200 on the male flange 120 contacts the female terminal 300 in the female socket 101, thereby enabling signal transmission.
[0056] like Figure 6 As shown, the first grounding plate 400 and the second grounding plate 500 are respectively disposed at both ends of the insulating base 100. When the two board-to-board connectors 10 are fastened together, they combine... Figure 8 and Figure 9 The first grounding piece 400 of one board-to-board connector 10 contacts the second grounding piece 500 of the other board-to-board connector 10, and the second grounding piece 500 of one board-to-board connector 10 contacts the first grounding piece 400 of the other board-to-board connector 10.
[0057] Continue to refer to Figure 6 The grounding plate 600 is disposed on the insulating base 100, and is located at the midpoint of the insulating base 100 along its length (X direction). (Reference) Figure 6 As shown, the grounding piece 600 is roughly set at the connection position between the male connector 10a and the female connector 10b, that is, between the male connector 10a and the female connector 10b. The grounding piece 600 is set at the position between the male connector 10a and the female connector 10b.
[0058] like Figure 7 As shown, the male seat flange 120 includes two male seat long flanges 121 and one male seat wide flange 122. The two male seat long flanges 121 are respectively disposed on both sides of the base plate 110 along its width direction (Y direction), and the long flanges extend along the long side of the insulating seat 100. Figure 7 As shown, the male seat wide flange 122 is disposed at one end of the insulating seat 100, and the two ends of the male seat wide flange 122 are respectively connected to the ends of the two male seat long flanges 121. The two male seat long flanges 121 and the male seat wide flange 122 form a semi-frame structure.
[0059] like Figure 7 As shown, the female seat flange 130 includes two long female seat flanges 131 and one wide female seat flange 132. The two long female seat flanges 131 are respectively disposed on both sides of the base plate 110 along its width direction (Y direction). Figure 7 As shown, a wide flange 132 of the female seat is disposed at one end of the insulating seat 100, and the two ends of the wide flange 132 are respectively connected to the ends of two long flanges 131 of the female seat. The two long flanges 131 and the wide flange 132 of the female seat form a semi-frame structure.
[0060] like Figure 7As shown, there is a gap between the long flange 131 of the female connector and the island portion 140, which forms a long slot 1011. A short slot 1012 is formed between the wide flange 132 of the female connector and the island portion 140. The long slot 1011 and the short slot 1012 communicate to form the female connector slot 101. (Continue referring to...) Figure 7 The male seat long flange 121 and the male seat wide flange 122 together form the male seat slot 102.
[0061] like Figure 7 As shown, the insulating base 100 of the board-to-board connector 10 also includes a connecting flange 150. The connecting flange 150 is disposed between the male flange 120 and the female flange 130, and as shown... Figure 7 As shown, there are two connecting flanges 150, which are respectively disposed on both sides of the base plate 110. Each connecting flange 150 is connected at both ends to the corresponding male long flange 121 and female long flange 131. The connecting flanges 150 connect the male flange 120 and the female flange 130, enabling the flanges to be connected as a single unit and improving their strength.
[0062] like Figure 7 As shown, a connecting groove 103 is formed between the two connecting flanges 150. One end of the connecting groove 103 communicates with the male socket 102, and the other end communicates with the female socket 101. This creates a connecting groove in the middle of the connector, facilitating the insertion of two connectors.
[0063] As mentioned above, refer to Figure 1 The grounding plate 600 has a socket 611 and a plug arm 612 on its insertion portion 610. In this embodiment, combined with Figure 1 , Figure 6 and Figure 7 As shown, the socket 611 and the plug arm 612 are disposed on the connecting flange 150 corresponding to the plug portion 610 where the socket 611 and the plug arm 612 are located. Figure 1 As shown, the grounding plate 600 has two insertion parts 610, one at the front and one at the back, as follows: Figure 7 As shown, the insulating base 100 has two connecting flanges 150, front and rear, which are combined with Figure 1 , Figure 6 and Figure 7 The socket 611 and the plug arm 612 on the front plug portion 610 of the grounding plate 600 are provided on the front connecting flange 150 of the insulating base 100. The socket 611 and the plug arm 612 on the front plug portion 610 of the grounding plate 600 are provided on the front connecting flange 150 of the insulating base 100. The connecting flange 150 supports the plug portion 610, which can improve the strength of the plug portion 610.
[0064] It is understandable that, such as Figure 7As shown, the connecting flange 150 is provided with a clearance hole 151, which is combined with Figure 6 and Figure 7 The clearance hole 151 on the connecting flange 150 is used to avoid the socket 611 on the third grounding piece 600, thereby avoiding the insertion arm 612 of the two connectors after they are engaged and inserted into the socket 611.
[0065] In this embodiment, the grounding plate 600, the first grounding plate 400, the second grounding plate 500, the male terminal 200, and the female terminal 300 are all integrally formed with the insulating base 100 by injection molding, thereby embedding the grounding plate 600, the first grounding plate 400, the second grounding plate 500, the male terminal 200, and the female terminal 300 onto the insulating base 100. After injection molding, the board-to-board connector 10 of this embodiment can be formed by cutting. The process is simple and the cost is low.
[0066] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0067] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
