[0002] With the upgrading and evolution of electronic equipment, the volume and transmission rate of communication data in the electronic equipment have been significantly improved. In order to meet the signal transmission requirements of the electronic equipment, the transmission performance of various devices in the electronic equipment needs to be upgraded. Taking the commonly used connector in the electronic equipment as an example, as an important component of the electronic equipment, the connector is mainly used for connecting between multiple electronic assemblies to realize signal transmission between the electronic assemblies.
[0003] In the current electronic equipment, the connector is an important link in signal transmission, and its signal transmission rate and bandwidth have important influence on the running rate of the electronic equipment and the frequency range of the transmitted signal. The specific structure of the terminal of the connector as an important node for transmitting the signal directly affects the signal transmission rate and bandwidth of the connector. In order to achieve the purpose of guiding and pre-pressing, the end of the terminal usually includes a stub, but the electromagnetic effect of the stub limits the improvement of the signal transmission rate and the expansion of the bandwidth.

The terminal includes an electrical connection part and an extension part, the electrical connection part is a metal structure, and the extension part is an insulating structure. The electrical connection part includes a first end and a second end, the first end is fixedly connected with the fixed structure, and the second end is fixedly connected with the extension part; that is, one end of the terminal away from the fixed structure is fixedly connected with the extension part. The extension part serves as a guide structure of the terminal and provides a pre-pressing force for the terminal. The terminal includes a contact point located at the electrical connection part, and the distance between the contact point and the end face of the second end is less than or equal to 0.8 mm. The extension part in the present application embodiment plays a guiding and pre-pressing role while limiting the transmission rate and bandwidth of the signal less, which is conducive to improving the signal transmission rate and bandwidth of the connector, and is particularly suitable for connectors for transmitting high-speed signals and / or high-frequency signals. In addition, the preparation precision requirement of the terminal and the connector is low, and the structure of the connector is simple, which is conducive to reducing the cost of the connector.
[0006] In a further technical solution, the distance between the contact of the terminal and the end face of the second end of the electric connection part is greater than or equal to 0.4 mm. The distance between the contact and the end face of the second end can absorb manufacturing tolerances, and the contact can be reliably connected with the opposite connector even if there is some deviation. This is also conducive to reducing the preparation process of the terminal, and the precision requirement for the connection between the extension part and the electric connection part is also low, which is conducive to simplifying the preparation process of the terminal.
[0007] The strength of the extension part of the terminal is greater than or equal to 0.2 N. This is conducive to improving the guiding effect of the extension part and improving the pre-pressing force of the terminal, thereby improving the connection reliability of the connector and the opposite connector.
[0008] In order to connect the extension part, the electric connection part of the terminal can include a connection region and a fixing region, wherein the connection region is used for electrically connecting with the opposite connector, and the contact is located in the connection region; and the fixing region is used for fixedly connecting with the extension part. The extension part is fixed to the fixing region, and the length of the extension part along the arrangement direction of the connection region and the fixing region is 0.3 mm to 0.7 mm. The length of the extension part along the arrangement direction of the connection region and the fixing region is at least 0.3 mm, which is conducive to improving the pre-pressing force generated by the terminal of the connector. In addition, the length of the extension part along the arrangement direction of the connection region and the fixing region is not more than 0.7 mm, which does not easily affect the signal transmitted by the terminal.
[0009] In a technical solution, the length of the extension part along the thickness direction of the fixing region is 0.2 mm to 0.5 mm. The thickness of the extension part is at least 0.2 mm, which is conducive to improving the thickness of the extension part, thereby improving the strength and rigidity of the extension part. In addition, the thickness of the extension part is not more than 0.5 mm, which is conducive to improving the miniaturization degree of the terminal and reducing the volume of the connector.
[0010] In a technical solution, the length of the extension part along the first direction is 0.18 mm to 0.36 mm, the first direction is perpendicular to the arrangement direction of the connection region and the fixing region, and the first direction is perpendicular to the thickness direction of the fixing region. This is conducive to improving the strength and rigidity of the extension part, and is conducive to improving the miniaturization degree of the terminal and reducing the volume of the connector.

The stepped surface is used to accommodate part of the extension part, so that the surface of the extension part facing the side where the contact is located is a third surface, and the first surface and the third surface smoothly transition, which is beneficial to improve the guiding effect of the terminal.
[0013] In one technical solution, the fixed area has grooves on both sides along a first direction, the first direction is perpendicular to the arrangement direction of the connection area and the fixed area, and the first direction is perpendicular to the thickness direction of the fixed area. This is beneficial to improve the fixing strength of the extension part and the electrical connection part and improve the structural reliability.
[0014] The length of the extension part along the first direction is greater than the maximum length of the fixed area along the first direction, the first direction is perpendicular to the arrangement direction of the connection area and the fixed area, and the first direction is perpendicular to the thickness direction of the fixed area. The extension part wraps the fixed area on both sides of the fixed area along the first direction, thereby improving the fixing strength of the extension part and the electrical connection part.
[0015] In another technical solution, the surface of the connection area facing the outer side surface is a first surface, the surface of the fixed area facing the side where the contact is located is a second surface, and the first surface and the second surface smoothly transition; the extension part covers the second surface of the fixed area. The extension part protrudes from the first surface of the electrical connection part, which is beneficial to the extension part abutting against the fixed structure, thereby providing a pre-pressure. In this solution, grooves do not need to be prepared on the electrical connection part to fix the extension part, which is beneficial to simplify the manufacturing process of the terminal.
[0016] The surface of the extension part facing the side where the contact is located is a fourth surface, and the distance between the fourth surface and the second surface is less than or equal to 0.03. This makes the structure of the terminal more regular, can better play a guiding role, and the size of the terminal will not be too large. The greater the distance between the fourth surface and the second surface, the more likely it is to cause a contact risk. Since the fourth surface and the second surface are not necessarily parallel, the distance between the fourth surface and the second surface refers to the maximum distance.

In this solution, the fixing area of metal material is 3D printed on the end surface of the connecting area of metal material, and the connecting strength is strong. Then, the extension part is directly 3D printed on the end surface of the fixing area. Although the material of the extension part is different from that of the fixing area, the extension part can be formed at one time, and thus the connecting strength between the extension part and the fixing area is strong.

Figure 4 and Figure 5As shown, in the embodiment of the application, the terminal 11 of the connector includes an electrical connection part 111 and an extension part 112. The electrical connection part 111 includes a first end 1111 and a second end 1112. It can be understood that the two ends of the electrical connection part 111 in the extension direction are the first end 1111 and the second end 1112, respectively. The first end 1111 of the electrical connection part 111 is fixedly connected with the fixed structure 12, so that the terminal 11 is fixed to the fixed structure 12.

Therefore, the extension part 112 in the embodiment of the application plays a guiding and pre-pressing role while limiting the signal transmission rate and bandwidth, which is beneficial to improving the signal transmission rate and bandwidth of the connector, and is particularly suitable for connectors for transmitting high-speed signals and / or high-frequency signals. In addition, the preparation precision of the terminal 11 and the connector is low, and the structure of the connector is simple, which is beneficial to reducing the cost of the connector.
[0066] For reference Figure 5 In an embodiment, the distance L1 between the contact 113 of the electrical connection part 111 and the end face of the second end 1112 is greater than or equal to 0.4 mm. In this embodiment, the distance between the contact 113 and the end face of the second end 1112 can absorb manufacturing tolerances, and the contact 113 can be reliably connected with the opposite connector even if it has some deviation. In addition, it is also beneficial to reduce the preparation process of the terminal 11, and the precision requirement of the connection between the extension part 112 and the electrical connection part 111 is also low, which is beneficial to simplifying the preparation process of the terminal 11.
[0067] In an optional embodiment, the distance L1 between the contact 113 and the end surface of the second end 1112 can be 0.45 mm, 0.5 mm, 0.53 mm, 0.55 mm, 0.58 mm, 0.6 mm, 0.65 mm, 0.67 mm, 0.7 mm, 0.72 mm, 0.75 mm or 0.78 mm. The distance L1 can be selected according to requirements, for example, according to the overall size of the terminal 11, or according to the performance requirements of the connector, etc.
[0068] In an embodiment, the extension 112 of the terminal 11 has a strength greater than or equal to 0.2 N. For example, the extension 112 of the terminal 11 can have a strength of 0.3 N, 0.4 N, 0.5 N, 0.6 N, 0.7 N, 0.8 N or 1 N. In this scheme, the extension 112 has a strong strength, which is beneficial to improve the guiding effect of the extension 112 and improve the pre-pressing force of the terminal 11, thereby improving the connection reliability of the connector and the opposite connector.
[0069] The size of the extension 112 can have various options. Figure 6 FIG. 1 shows a structure of a terminal according to an embodiment of the present application, Figure 7 FIG. 2 shows a partial lateral structure of a terminal according to an embodiment of the present application, and Figure 6 and Figure 7 In an embodiment, the electrical connection portion 111 includes a connection region 1113 and a fixing region 1114. The connection region 1113 is used for electrical connection with the opposite connector, and the contact 113 is located in the connection region 1113. The fixing region 1114 is used for fixed connection with the extension 112. The length L2 of the extension 112 along the arrangement direction X of the connection region 1113 and the fixing region 1114 is 0.3 mm to 0.7 mm. For example, the length L2 of the extension 112 along the arrangement direction X of the connection region 1113 and the fixing region 1114 can be 0.4 mm, 0.5 mm, 0.55 mm or 0.6 mm, etc. In this embodiment, the length L2 of the extension 112 along the arrangement direction X of the connection region 1113 and the fixing region 1114 is at least 0.3 mm, which is beneficial to improve the pre-pressing force of the terminal 11 of the connector. In addition, the length L2 of the extension 112 along the arrangement direction X of the connection region 1113 and the fixing region 1114 is not more than 0.7 mm, which is not easy to affect the signal transmitted by the terminal 11.
[0070] Please continue to refer to Figure 6 and Figure 7In an embodiment, the length L3 of the extension 112 along the thickness direction Y of the fixing area 1114 is 0.2mm-0.5mm. For example, the length L3 of the extension 112 along the thickness direction Y of the fixing area 1114 can be 0.3mm, 0.35mm, 0.4mm, 0.42mm, 0.45mm or 0.48mm. In this embodiment, the length L3 of the extension 112 along the thickness direction Y is at least 0.2mm, which is conducive to increasing the thickness of the extension 112 and thus increasing the strength and rigidity of the extension 112. Moreover, the length L3 of the extension 112 along the thickness direction Y is not more than 0.5mm, which is conducive to increasing the miniaturization degree of the terminal 11 and reducing the volume of the connector.

Figure 8 In an embodiment, the length L4 of the extension 112 along the first direction Z is 0.18mm-0.36mm. For example, the length L4 of the extension 112 along the first direction Z is 0.2mm, 0.23mm, 0.25mm, 0.3mm, 0.32mm or 0.35mm. The first direction Z is perpendicular to the arrangement direction X of the connecting area 1113 and the fixing area 1114, and the first direction Z is perpendicular to the thickness direction Y of the fixing area 1114. This scheme is also conducive to increasing the strength and rigidity of the extension 112 and increasing the miniaturization degree of the terminal 11 and reducing the volume of the connector.
[0072] In an embodiment of the present application, the fixing mode of the electric connection part 111 of the terminal 11 and the extension 112 has multiple choices. For example, the electric connection part 111 and the extension 112 are injection molded structures, or the electric connection part 111 and the extension 112 are injection molded structures. In this scheme, the fixing strength of the electric connection part 111 and the extension 112 is better, and the preparation process is simple.
[0073] Figure 9 FIG. 6 is a schematic view of a partial lateral structure of a terminal according to an embodiment of the present application. Figure 9As shown, in an embodiment, the surface of the connecting area 1113 facing the outer side surface is a first surface 11131, the surface of the fixing area 1114 facing the side where the contact 113 is located is a second surface 11141, the first surface 11131 and the second surface 11141 form a stepped surface, and the extension 112 covers the second surface 11141 of the fixing area 1114. From the side where the contact 113 is located, the second surface 11141 is recessed from the first surface 11131 of the connecting area 1113. In order to form the above-mentioned stepped surface, in an embodiment, the electrical connection part 111 can be bent to form the above-mentioned stepped surface, at which time the thickness of the connecting area 1113 is the same as the thickness of the fixing area 1114. Alternatively, in an embodiment, part of the metal structure of the fixing area 1114 can be removed, for example, a groove is formed, to form the above-mentioned stepped surface, at which time the thickness of the connecting area 1113 is greater than the thickness of the fixing area 1114. The surface of the extension 112 facing the side where the contact 113 is located is a third surface 1121, and the first surface 11131 and the third surface 1121 smoothly transition. In this embodiment, the extension 112 smoothly transitions with the connecting area 1113 of the electrical connection part 111, which is conducive to improving the guiding effect of the terminal 11.
[0074] As shown in FIG. 1, Figure 8 In an embodiment, the fixing area 1114 of the electrical connection part 111 has a groove on both sides along the first direction Z, the first direction Z is perpendicular to the arrangement direction X of the connecting area 1113 and the fixing area 1114, and the first direction Z is perpendicular to the thickness direction Y of the fixing area 1114, for example, the above-mentioned first direction Z can be understood as the width direction of the fixing area 1114. In a specific embodiment, the above-mentioned groove can be a square groove, or can also be an arc-shaped groove, etc., which is not limited in the present application. In this embodiment, the extension 112 can be fixed in the above-mentioned groove and form a partially clamped structure with the fixing area 1114, which is conducive to improving the fixing strength of the extension 112 and the electrical connection part 111 and improving the structural reliability.
[0075] As shown in FIG. 1, Figure 6 and Figure 8 In an embodiment, the length of the extension 112 along the first direction Z is greater than the maximum length of the fixing area 1114 along the first direction Z. This allows the extension 112 to wrap around the fixing area 1114 on both sides along the first direction, thereby improving the fixing strength of the extension 112 and the electrical connection part 111.
[0076] Figure 10 FIG. 1 is a structural schematic diagram of a terminal in an embodiment of the present application, Figure 11 FIG. 2 is a partial structural schematic diagram of a terminal in an embodiment of the present application, Figure 12 FIG. 3 is a partial structural schematic diagram of a terminal in an embodiment of the present application. As shown in FIG. 3, Figure 10 , Figure 11 andFigure 12 As shown, in one embodiment, the surface of the connection area 1113 of the electrical connection portion 111 facing the outer surface is the first surface 11131, and the surface of the fixing area 1114 facing the side where the contact 113 is located is the second surface 11141. The first surface 11131 and the second surface 11141 transition smoothly. The extension 112 covers the second surface 11141 of the fixing area 1114, causing the extension 112 to protrude from the first surface 11131 of the electrical connection portion 111. This facilitates the abutment of the extension 112 against the fixing structure 12, thereby providing pre-pressure. In this design, it is unnecessary to prepare a groove in the electrical connection portion 111 to fix the extension 112, which simplifies the manufacturing process of the terminal 11.
[0077] Specifically, such as Figure 10 and Figure 11 As shown, the surface of the extension 112 facing the contact 113 is the fourth surface 1122, and the distance between the fourth surface 1122 and the second surface 11141 is less than or equal to 0.03 mm. This distance between the fourth surface 1122 and the second surface 11141 can be understood as the height by which the extension 112 protrudes from the connection area 1113. For example, the distance between the fourth surface 1122 and the second surface 11141 can be 0.01 mm or 0.02 mm, making the structure of the terminal 11 more regular, providing better guidance, and preventing the terminal 11 from being too large. A larger distance between the fourth surface 1122 and the second surface 11141 increases the risk of contact. Since the fourth surface 1122 and the second surface 11141 are not necessarily parallel, the distance between them in this case refers to the maximum distance.
[0078] Figure 13 This is a partial cross-sectional view of a terminal in an embodiment of this application, as shown below. Figure 13 As shown, in one embodiment, the fixing area 1114 of the electrical connection 111 can be a dovetail-shaped protrusion, and the extension 112 includes a dovetail-shaped groove, in which the dovetail-shaped protrusion is accommodated. The cross-section of the dovetail-shaped protrusion along the direction perpendicular to the arrangement direction of the connecting area 1113 and the fixing area 1114 gradually increases away from the connecting area 1113, which helps to enhance the connection reliability between the extension 112 and the electrical connection 111. The dovetail-shaped protrusion and the dovetail-shaped groove can form a tenon-and-mortise structure, so that the extension 112 is riveted to the fixing area 1114. Alternatively, the extension 112 can also be welded to the fixing area 1114, thereby improving the fixing strength between the extension 112 and the fixing area 1114.
[0079] Figure 14 This is a partial structural diagram of a terminal in an embodiment of this application, such as... Figure 14As shown, in one embodiment, the fixing area 1114 of the terminal 11 and the extension 112 are sequentially 3D printed on the electrical connection part 111. In this scheme, the fixing area 1114 of the metal material is 3D printed on the end surface of the connection area 1113 of the metal material, the connection strength is strong, and then the extension 112 is directly 3D printed on the end surface of the fixing area 1114. Although the material of the extension 112 is different from that of the fixing area 1114, it can be formed at one time, so the connection strength of the extension 112 and the fixing area 1114 is also strong. Moreover, the preparation process is relatively simple.
[0080] Based on the same inventive concept, the application further provides a signal transmission method of an electronic device, which transmits signals by using the electronic device provided in the third aspect. The signal transmission method specifically includes: transmitting a data signal by a terminal of a connector. By using the method, the transmission rate and bandwidth of the connector for transmitting signals can be improved after being absorbed.

Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
