Description

Technical Field

[0001] The present application relates to the technical field of high-speed electrical connectors, and in particular to a conductive terminal assembly. Background Art

[0002] As a key component for high-speed data transmission between electronic system equipment, high-speed electrical connectors are widely used in computers, communications, automobiles, aerospace and other fields. With the rapid development of industries such as communications, automobiles, consumer electronics, and industrial control, and the promotion of technologies such as 5G, the Internet of Things, and artificial intelligence, the transmission rate requirements for high-speed connectors are also getting higher and higher. The conductive terminals have specific structures and material properties to ensure the integrity, stability and efficient transmission of the signal. The male head is inserted into the high-speed electrical connector to achieve the connection of the high-speed electrical connector. The high-speed electrical connector is usually set on the circuit board for transmitting signals.

[0003] In the related art, the terminal includes a mounting piece and a connecting piece. The connecting piece is made of metal and is fixed on the mounting piece.

[0004] Since the terminals need to maintain contact reliability and electrical signal transmission at the same time, in order to maintain contact reliability, the connector needs to have sufficient elasticity, so the connector needs to have sufficient thickness to ensure the positive force. In order to maintain electrical signal transmission, the connector needs to be thinner to ensure fast signal transmission. Therefore, it is difficult to achieve good contact reliability and electrical signal transmission at the same time, making it difficult for high-speed electrical connectors to meet the requirements of the next generation of communication equipment for higher transmission rates. Summary of the invention

[0005] In order to improve the problem that it is difficult for terminals to ensure contact reliability and electrical signal transmission, the present application provides a conductive terminal assembly.

[0006] The present application provides a conductive terminal assembly, which adopts the following technical solution: A conductive terminal assembly includes a mounting member and a connecting member, wherein the connecting member includes a transmission end and a fixed end, wherein the fixed end and the transmission end are both fixedly connected to the mounting member, wherein the fixed end is located on a side of the transmission end away from a male head, wherein the fixed end is used to apply a force to the transmission end toward the male head, and wherein the transmission end is used to transmit electrical signals.

[0007] By adopting the above technical solution, when the male plug is inserted into the terminal, the male plug abuts against the transmission end, causing the transmission end to deform in the direction away from the male plug. At this time, the fixed end is located on the side of the transmission end away from the male plug, and the fixed end applies a force toward the male plug side to the transmission end, so that the fixed end applies a positive force to the transmission end, so that the transmission end and the male plug can be in more stable contact, so that the connector has sufficient positive force to maintain the transmission of electrical signals; at the same time, the fixed end supports the transmission end, and the transmission end does not need to be too thick, so that the transmission end can ensure fast signal transmission.

[0008] Optionally, the transmission end is formed on a side of the fixed end facing the male connector through a metallization process.

[0009] By adopting the above technical solution, the transmission end is formed on the side of the fixed end facing the male head through a metallization process, so that the thickness of the transmission end is thin enough, and the fixed end serves as a support for the transmission end, so that the transmission end can be fixed to the male head more stably; since the thickness of the transmission end is reduced, the distance between two adjacent transmission ends can be reduced and the width of the transmission end can be reduced, thereby increasing the strong coupling of the transmission end, eliminating the short pile effect, and thereby improving the signal transmission rate of the transmission end.

[0010] Optionally, a boss is provided on the fixed end, the transmission end abuts against the boss, and the transmission end abutting against the boss is used to abut against a male head.

[0011] By adopting the above technical solution, since the metallization process of the transmission end is formed on the fixed end, the transmission end is thin enough, and the boss supports the transmission end, so that the transmission end can be stably connected to the male head.

[0012] Optionally, the transmission end includes a contact portion and a main body portion, the contact portion is integrally formed on the main body portion, the main body portion is arranged on the mounting member, an arc surface for abutting the male head is formed on the contact portion, and there is a gap between the arc surface away from the surface of the mounting member and the fixed end.

[0013] By adopting the above technical solution, the arc surface of the contact part abuts against the male head, so that the arc surface and the male head can be better connected; at the same time, since there is a gap between the arc surface away from the surface of the mounting part and the fixed end, the contact part does not need to form a complete arc surface, and part of the arc surface can abut against the male head, which saves some materials and reduces costs; at the same time, the overall volume of the contact part is reduced, and the signal transmission speed of the contact part is further improved.

[0014] Optionally, the transmission end includes a contact portion and a main body portion, the contact portion is integrally formed on the main body portion, the contact portion is arranged on the mounting member, the fixed end abuts against a side of the contact portion away from the male head, and when the main body abuts against the male head, the contact portion is deformed.

[0015] By adopting the above technical solution, the male plug is inserted into the terminal, and the male plug drives the contact part to deform. The fixed end abuts against the side of the contact part away from the male plug, so that the fixed end can stably support the contact part and avoid the transmission end from being offset during the deformation process.

[0016] Optionally, the fixing end, the contact portion and the mounting member are arranged in a triangle.

[0017] By adopting the above technical solution, the fixed end, the contact part and the mounting piece form a triangle arrangement with each other, so that the fixed end supports the contact part, so that the part of the contact part that is deformed changes from the position where the contact part abuts the mounting piece to the position where the fixed end abuts the contact part, thereby making the connection between the contact part and the mounting piece less susceptible to damage due to excessive deformation.

[0018] Optionally, the fixing end abuts against the contact portion on the side facing the male connector.

[0019] By adopting the above technical solution, the fixed end abuts against the contact part with the side of the male head, and the contact area between the fixed end and the contact part is larger, so that the pressure applied by the fixed end to the contact part is smaller, so that the contact part is not easily damaged by excessive force, and the connection between the fixed end and the contact part can be more stable.

[0020] Optionally, the contact portion is provided with a movable groove, and the movable groove is used for the fixed end to slide.

[0021] By adopting the above technical solution, when the male plug is inserted into the terminal, the male plug drives the contact portion to deform toward the side away from the male plug, allowing the fixed end to slide in the movable groove. The fixed end can be deformed toward the side away from the male plug, and the contact area between the fixed end and the contact portion can be increased, so that the pressure applied by the fixed end to the contact portion is further reduced, making the contact portion less likely to be damaged when deformed.

[0022] Optionally, a covering portion is integrally formed on the fixed end, and the covering portion and the fixed end are arranged around the transmission end.

[0023] By adopting the above technical solution, the covering part and the fixed end are arranged around the transmission end, and the covering part can stably protect the transmission end, and prevent the transmission end from bending due to shaking during the transportation or assembly of the terminal, thereby ensuring that the transmission end can stably support and transmit electrical signals.

[0024] Optionally, an annular groove is provided on the transmission end, the fixed end and the covering portion are both arranged in the annular groove, and the fixed end or the covering portion is fixedly connected to the mounting member.

[0025] By adopting the above technical solution, the fixed end and the covering part are both arranged in the annular groove, so that the thickness of the transmission end can be thinner, the transmission speed of the transmission end can be faster, and the electrical signal transmission capacity of the terminal is enhanced.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the male plug is inserted into the terminal, the male plug abuts against the transmission end, causing the transmission end to deform in the direction away from the male plug. At this time, the fixed end is located on the side of the transmission end away from the male plug, and the fixed end applies a force toward the side of the male plug to the transmission end, so that the fixed end applies a positive force to the transmission end, so that the transmission end and the male plug can be in more stable contact, so that the connector has enough positive force to maintain the transmission of electrical signals; at the same time, the fixed end supports the transmission end, and the transmission end does not need to be too thick, so that the transmission end can ensure fast signal transmission.

[0027] 2. The transmission end is electroplated on the side of the fixed end facing the male head, so that the thickness of the transmission end is thin enough, and the fixed end serves as a support for the transmission end, so that the transmission end can be fixed to the male head more stably.

[0028] 3. By abutting the contact part with the side of the fixed end toward the male head, the contact area between the fixed end and the contact part is larger, so that the pressure applied by the fixed end to the contact part is smaller, so that the contact part is not easily damaged by excessive force, and the connection between the fixed end and the contact part can be more stable.
