[0039] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many other forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] like Figure 1-6 As shown, in one embodiment of a terminal structure, the terminal structure includes a main body 1 and a lever assembly, the lever assembly including a first lever 2 and a second lever 3. The main body 1 has a first end 11 and a second end 12 relative to each other. The first lever 2 and the second lever 3 are both connected to the end surface of the second end 12 facing away from the first end 11, and the connection points are respectively located at both ends of the end surface of the first end 11. The first lever 2 includes a first section 21 and a second section 22. One end of the first section 21 is connected to the first end 11, and the other end is connected to the second section 22. The first section 21 is bent toward the middle of the first end 11 and in a direction away from the second lever 3, so that the second section 22 can be opposite to the second lever 3 to form a clamping space.

[0043] In this embodiment, a clamping space is formed by connecting a first force arm 2 and a second force arm 3 on a main body 1, and bending the first force arm 2 toward the middle of the first end 11 of the main body 1 and away from the second force arm 3. It can be understood that the force arm is made of conductive metal and has elasticity. In this embodiment, a clamping space is formed after the second section 22 is opposite to the second force arm 3, and then the second section 22 and the second force arm 3 are stretched by inserting other terminals into the clamping space, and the elastic force generated can form an effect of clamping the inserted terminal, and because of the relative setting after twisting, it is conducive to achieving more stable clamping, which can avoid signal interruption and solve the technical problem of unstable clamping of the existing terminal structure. It is also conducive to improving the terminal arrangement density after the connector is formed, thereby bringing better performance.

[0044] In one terminal structure embodiment, the second force arm 3 includes a third section 31 and a fourth section 32, one end of the third section 31 is connected to the first end 11, and the other end is connected to the fourth section 32, and the third section 31 is bent toward the middle of the first end 11 and bent in a direction away from the first force arm 2, so that the fourth section 32 can be opposite to the second section 22 at a position corresponding to the middle of the first end 11.

[0045] In this embodiment, combined with the previous embodiment, specifically, the main body 1 can be a plate-like structure, the first force arm 2 and the second force arm 3 are first bent in the direction away from each other, and then both are bent toward the middle of the first end 11 of the main body 1, which can form a cross or other relative structure, all of which are complete toward the middle, which can be more convenient to arrange, and avoid excessive bending of a single force arm, forming a more stable clamping force arm group.

[0046] In one embodiment of the terminal structure, the orthographic projection of the arm assembly onto a first plane is an axisymmetric figure, and the first plane is disposed at an angle to the end face of the first end 11. And / or, the orthographic projection of the arm assembly onto a second plane is an axisymmetric figure, and the second plane is perpendicular to the first plane and disposed at an angle to the end face of the first end 11.

[0047] In this embodiment, referring to Figure 2-4 As shown, the first plane is not parallel to the end face of the first end 11. By setting it to be an axisymmetric figure when projected relative to the first plane, a symmetrical state can be formed, thereby achieving a more stable clamping effect. In addition, the second plane is similarly capable of achieving a more stable clamping effect. When the orthographic projections toward the first and second planes are both axisymmetric structures, a relatively symmetrical state can be formed on two perpendicular planes such as XX and YY, which can be understood as a front view and a side view. For this reason, the bent second section 22 and fourth section 32 are symmetrical in structure, thus achieving a more stable clamping, avoiding asymmetric clamping force, and preventing signal interruption.

[0048] Preferably, the first plane and the second plane are both perpendicular to the end surface of the first end 11. When the end surface of the first end 11 is a rectangular surface, it can be understood that the first plane and the second plane can be two axially symmetrical planes of the rectangular surface.

[0049] In one terminal structure embodiment, the second section 22 includes a first segment 221 and a second segment 222, one end of the first segment 221 is connected to the first section 21, and the other end is connected to the second segment 222, the first segment 221 and the second segment 222 are arranged at an angle to form a first bending portion 223, and the opening of the first bending portion 223 is facing away from the second force arm 3.

[0050] In this embodiment, it can be understood that the second segment 222 can be formed by bending in a direction away from the second lever arm 3, so that it is easy to guide the terminal into between the first lever arm 2 and the second lever arm 3, and the first bent portion 223 formed during the bending process can also be closer to the second lever arm 3 to form a portion for clamping the inserted terminal.

[0051] In one terminal structure embodiment, the fourth section 32 includes a third segment 321 and a fourth segment 322, one end of the third segment 321 is connected to the third segment 31, and the other end is connected to the fourth segment 322, and the third segment 321 and the fourth segment 322 are arranged at an angle to form a second bending portion 323, and the opening of the second bending portion 323 is facing away from the first force arm 2.

[0052] In this embodiment, similarly, the fourth segment 322 can be formed by bending in a direction away from the first lever arm 2, so that the terminal can be easily guided into between the first lever arm 2 and the second lever arm 3, and the second bent portion 323 formed during the bending process can also be closer to the first lever arm 2 to form a portion for clamping the inserted terminal.

[0053] In combination with the previous embodiment, preferably, the first bend portion 223 and the second bend portion 323 are arranged relative to each other and abut against each other. It is understandable that when the two bend portions abut against each other, the first force arm 2 and the second force arm 3 form an X-shape, that is, an opening is formed between the second segment 222 and the fourth segment 322. The external terminal opens the opening, allowing the first bend portion 223 and the second bend portion 323 to separate and enter between the first segment 221 and the third segment 321. Due to the elasticity of the first force arm 2 and the second force arm 3, the first bend portion 223 and the second bend portion 323 will tightly clamp the inserted terminal.

[0054] In one embodiment of the connector, a male socket 4 and a female socket 5 are included. The male socket 4 includes a first mounting seat and the terminal structure described in the above embodiment. The first mounting seat is provided with an insertion hole 41. At least the arm assembly of the terminal structure is accommodated in the insertion hole 41. The female socket 5 is provided with a connecting terminal 6. When the male socket 4 and the female socket 5 are connected, the connecting terminal 6 can extend into the clamping space and contact both the first arm 2 and the second arm 3.

[0055] In this embodiment, by applying the terminal structure in the previous embodiment to the male socket 4, the connecting terminal 6 on the female socket 5 can be clamped more firmly, thereby achieving a better signal transmission effect and avoiding signal interruption.

[0056] In one connector embodiment, there are multiple terminal structures, each terminal structure is arranged along a first direction, there are multiple connecting terminals 6, each connecting terminal 6 is arranged at intervals along the first direction, and the female socket 5 is also provided with multiple signal terminals 7 arranged along the first direction, and two signal terminals 7 are provided between two adjacent connecting terminals 6. Each connecting terminal 6 and each signal terminal 7 extends into the clamping space one by one and contacts both the first force arm 2 and the second force arm 3.

[0057] In this embodiment, specifically, the connection terminal 6 may be a ground terminal. By providing two signal terminals 7 between adjacent ground terminals, the arrangement spacing between adjacent ground terminals can be made larger than the spacing between the signal terminals 7, thereby achieving high-frequency performance.

[0058] Preferably, the interval between the connection terminal 6 and the signal terminal 7 is equal to the interval between two adjacent signal terminals 7 .

[0059] In one embodiment of the connector, each terminal structure and its connected connecting terminals 6 and signal terminals 7 form a terminal row. There are at least two terminal rows, and each row of terminal rows is arranged along a second direction that is perpendicular to the first direction. In adjacent rows, the connecting terminals 6 in one terminal row are positioned opposite the two signal terminals 7 in the other terminal row.

[0060] In this embodiment, by providing at least two rows of terminal blocks, the signal terminal 7 can be surrounded by the ground terminal on three sides or more, which can fully meet the high-speed transmission performance.

[0061] Preferably, the grounding terminal is a U-shaped structure with two ends that can extend into the clamping space. The spacing between the two ends can be set to be larger than the spacing between the two signal terminals 7, so that the grounding terminal can better face the adjacent row signal and achieve a three-sided surround effect.

[0062] In one embodiment of the connector, the connector further includes a shielding member 9 , which is disposed between two rows of terminal blocks and abuts against each of the connecting terminals 6 in the two adjacent rows of terminal blocks.

[0063] In this embodiment, by providing a shielding member 9 to connect to the ground terminals in two adjacent rows of terminal blocks, high-frequency analysis capabilities can be improved. Specifically, the shielding member 9 can be a plate-shaped structural member embedded in the female connector 5, with connecting portions 91 extending from the shielding member at positions corresponding to the ground terminals to connect to each ground terminal.

[0064] In one embodiment of the connector, the second lever arm 3 includes a third section 31 and a fourth section 32. The third section 31 is connected to the first end 11 at one end and to the fourth section 32 at the other end. The third section 31 bends toward the middle of the first end 11 and away from the first lever arm 2, so that the fourth section 32 is opposite the second section 22 at a position corresponding to the middle of the first end 11. The second section 22 includes a first segment 221 and a second segment 222. The first segment 221 is connected to the first section 21 at one end and to the second segment 222 at the other end. The first segment 221 and the second segment 222 are arranged at an angle to form a first bend 223, with the opening of the first bend 223 facing away from the second lever arm 3. The fourth section 32 includes a third subsection 321 and a fourth subsection 322. One end of the third subsection 321 is connected to the third section 31, and the other end is connected to the fourth subsection 322. The third and fourth subsections 321 and 322 are arranged at an angle to form a second bend 323. The opening of the second bend 323 faces away from the first arm 2. A guide member 411 is provided on the inner wall of the entrance of the insertion hole 41 for the connection terminal 6 to extend in the direction of the connection terminal 6. The guide member 411 abuts the second subsection 222 and the fourth subsection 322.

[0065] In combination with the previous embodiment, by providing a guide component 411 on the inner wall of the plug hole 41 of the male socket 4, the ground terminal and the signal terminal 7 can be further guided to enter between the first lever arm 2 and the second lever arm 3, thereby avoiding abutting against the second segment 222 or the fourth segment 322 during the insertion process, thereby preventing the lever arm assembly from deforming and preventing the lever arm assembly from extending into the plug hole 41, thereby playing a role of limiting support.

[0066] Specifically, the guide component 411 may be an annular protruding structure, or include two protruding structures to abut against the second segment 222 and the fourth segment 322 in a one-to-one correspondence.

[0067] By applying the terminal structure and connector of the present invention, a better clamping effect and better high-frequency transmission performance can be achieved. In addition, the double-sided clamping can still ensure stable signal transmission between the ground terminal and the signal terminal 7 on the female socket 5 even when subjected to external impact. It can be understood that the second end 12 of the main body 1 is a first welding end 13 extending from the male socket 4. Specifically, the first welding end 13 can be a welding pad that can extend from the second end 12. The ground terminal and the signal terminal 7 both have a second welding end 8 extending from the female socket 5 away from the male socket 4.

[0068] like Figure 7-11 , a variety of simulation analyses were performed on the connector according to the PCIE5.0 standard, including characteristic impedance analysis, insertion loss analysis, return loss analysis, near-end crosstalk analysis, and far-end crosstalk analysis. The connector of this utility model can meet high-speed transmission performance and high-frequency performance.

[0069] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0070] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
