Description

Technical Field

[0001] This invention relates to a conductive terminal, and more particularly to a conductive terminal and an electrical connector using the conductive terminal. Background Technology

[0002] A conductive terminal is disclosed in the prior art, including a first terminal, a second terminal, and an elastic member. The first terminal is used to abut against a first electronic component, and the second terminal is used to abut against a second electronic component. The first terminal is cylindrical, and the second terminal is cylindrical and includes a receiving groove. Both the first terminal and the elastic member are received in the receiving groove of the second terminal. One end of the elastic member abuts against the bottom wall of the first terminal, and the other end abuts against the second terminal. Since the diameter of the first terminal is smaller than the diameter of the receiving groove, when the first terminal is abutted by the first electronic component, it will be deflected in the receiving groove. Sometimes it abuts against the groove wall, and sometimes it does not abut against the groove wall. The current flow between the first electronic component and the second electronic component is mainly transmitted through the first terminal to the elastic member, and then through the elastic member to the second terminal.

[0003] In this prior art, because the first terminal will be deflected in the receiving groove, sometimes it will abut against the groove wall and sometimes it will not. The current flow between the first electronic component and the second electronic component is mainly transmitted through the first terminal to the elastic member and then through the elastic member to the second terminal. The transmission path is long, the speed is low, and the high-frequency performance is not very good. Even if the first terminal abuts against the groove wall, the part of the first terminal abutting against the groove wall is different each time, which makes the transmission path from the first electronic component to the second electronic component uncertain each time, thus affecting the high-frequency performance.

[0004] Therefore, it is necessary to provide an improved high-frequency conductive terminal and electrical connector to overcome at least some of the aforementioned defects. Summary of the Invention

[0026] Compared with the prior art, the present invention has the following beneficial effects: After the first terminal and the second terminal of the present invention move relative to each other in the vertical direction Z, the first abutting part abuts against the second terminal, and the second abutting part abuts against the first terminal. This not only ensures that the abutting position of the first terminal and the second terminal is the same each time, and that the transmission path is the same, but also allows the current between the first mating element and the second mating element to be transmitted through the first conductive part, the abutting part and the abutting point of the first terminal, the abutting point of the first abutting part and the second terminal, and the second conductive part, without relying on elastic elements for current transmission. This shortens the current transmission path. Furthermore, the abutting part of the second terminal and the abutting part of the second terminal together achieve dual-channel path transmission between the first terminal and the second terminal, improving the transmission rate. In addition, along the vertical direction Z, the first abutting part is closer to the second conductive part relative to the first conductive part, and the second abutting part is closer to the first conductive part relative to the second conductive part. The distance from the first abutting part to the abutting point of the second abutting part and the first terminal exceeds half the height of the first terminal in the vertical direction Z, and exceeds half the height of the second terminal in the vertical direction Z. This is beneficial for increasing the length of the dual-channel path transmission between the first terminal and the second terminal, further improving the transmission rate.

Detailed Implementation Methods

[0028] In the following description, it should be noted that the terms "upper", "lower", "lateral", "width", "top", "bottom", "vertical", "inner", "outer", "middle", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the position or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. It should be noted that when an element is referred to as "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element.

[0030] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this invention, the first direction Y is defined as the Y direction, the second direction X is defined as the X direction, and the vertical direction Z is defined as the Z direction. The first direction Y and the second direction X are mutually perpendicular and both perpendicular to the vertical direction Z. It is understood that the orientation positioning of this invention is for better understanding the relative positional relationships and directions of movement between components. In actual use, the orientation positioning of this invention can be adjusted according to the application environment.

[0032] like Figures 1 to 14 As shown in the first embodiment of the present invention, the electrical connector 100 includes a conductive base 1, a body 2 disposed on the conductive base 1, and a plurality of conductive terminals 3 disposed on the body 2. The conductive terminals 3 are used to transmit signals. The electrical connector 100 electrically connects a first mating member 200 and a second mating member 300 through the conductive terminals 3. In this embodiment, the first mating member 200 is a chip module and the second mating member 300 is a circuit board. Of course, in other embodiments, the conductive terminals 3 can also electrically connect other types of components, such as the first mating member 200 being a circuit board and the second mating member 300 being a cable.

[0033] like Figure 1 and Figure 2 As shown, along the vertical direction Z, the conductive base 1 is formed by stacking multiple metal sheets 11. The conductive base 1 is provided with multiple through holes 12, a first mating structure 13, and a second mating structure 14. The through holes 12 can be formed by stamping. The first mating structure 13 connects to the first mating member 200, and the second mating structure 14 connects to the second mating member 300, forming a common ground shield. Specifically, the first mating structure 13 and the second mating structure 14 are both spring sheets. In other embodiments, the first mating structure 13 and the second mating structure 14 can be other metal materials that can abut, such as metal sponge, metal hooks, etc. The base body 2 includes multiple insulators 2', which are specifically made of insulating material, so that the multiple conductive terminals 3 are electrically isolated from the conductive base 1. However, in other embodiments, the base body 2 can also be made of conductive material, as long as the conductive terminals 3 used to transmit signals are electrically insulated from the base body 2 by insulating material barriers. Multiple insulators 2' are disposed in multiple through holes 12 in a one-to-one correspondence, and the multiple insulators 2' are spaced apart from each other. Each insulator 2' is provided with two mounting holes 21. Each mounting hole 21 passes through a first surface 22 and a second surface 23 disposed opposite to each other in the vertical direction Z. Multiple conductive terminals 3 are installed in the multiple mounting holes 21 in a one-to-one correspondence. Specifically, in this embodiment, the first surface 22 corresponds to the upper surface of the base 2, and the second surface 23 corresponds to the lower surface of the base 2.

[0034] like Figure 1 and Figure 2As shown, the insulator 2' includes a first stop 24 and a second stop 25 corresponding to each mounting hole 21. The first stop 24 and the second stop 25 restrict the conductive terminal 3 in the vertical direction Z, preventing the conductive terminal 3 from detaching from the corresponding mounting hole 21. It can be understood that in this embodiment, the insulator 2' is a one-piece plastic component, with the first stop 24 and the second stop 25 directly formed within the mounting hole 21 of the insulator 2'. A portion of the upper opening of the mounting hole 21 corresponds to the first stop 24, and a first fixture is positioned above the first stop 24 through the upper opening of the mounting hole 21; a portion of the lower opening of the mounting hole 21 corresponds to the second stop 25, and a second fixture is positioned below the second stop 25 through the lower opening of the mounting hole 21; alternatively, the insulator 2' is composed of upper and lower parts assembled together, with the first stop 24 formed on the upper part of the insulator 2'. The second stop 25 is formed in the lower part of the mounting hole 21; or, the insulator 2' is integrally formed, and one of the first stop 24 and the second stop 25 is formed in the mounting hole 21, while the other is a limiting film or protrusion provided outside the mounting hole 21, which is fixed to the insulator 2' by means of bonding, adhesive, or hot-melt fixing, or it can be a protrusion integrally formed with the insulator 2', and then its shape is changed by hot-melt, that is, it protrudes into the mounting hole 21 to play a limiting role. There is no limitation here, and it can be selected according to the actual situation. The first stop 24 is formed in the mounting hole 21 and is located on the side of the mounting hole 21 adjacent to the second surface 23. Specifically, the mounting hole 21 is formed by injection molding to form a width difference to form a limiting step surface. The second stop 25 is specifically a protrusion formed in the mounting hole 21 and flush with the first surface 22 of the insulator 2', thereby preventing the conductive terminal 3 from coming out of the second surface 23. Compared to the insulator 2' being formed by assembling two insulators 2', the insulator 2' being integrally formed in this embodiment reduces the assembly process of the insulator 2'. At the same time, if the mounting hole 21 formed by assembling two insulators 2' is misaligned, it will affect the assembly of the conductive terminal 3 and the positioning accuracy. The integrally formed mounting hole 21 is more conducive to the smooth assembly of the conductive terminal 3 and the positioning accuracy.

[0035] like Figures 8 to 10 and Figure 13 As shown, each mounting hole 21 includes a first guide groove 26 and a second guide groove 27, the first guide groove 26 and the second guide groove 27 are spaced apart from each other, a first stop 24 is provided below the first guide groove 26, and a second stop 25 is provided above the second guide groove 27. The first guide groove 26 and the second guide groove 27 each include two opposing wall surfaces M.

[0036] like Figures 1 to 2As shown, the two conductive terminals 3 located in the two mounting holes 21 of the same insulator 2' are a pair of differential signal terminals. The conductive terminal 3 includes a first terminal 31, a second terminal 32, and an elastic member 33. The first terminal 31 extends out of the second surface 23 and abuts against the second mating member 300. The second terminal 32 extends out of the first surface 22 and abuts against the first mating member 200. The elastic member 33 is located between the first terminal 31 and the second terminal 32 and is electrically connected to the first terminal 31 and the second terminal 32. Specifically, in this embodiment, the first terminal 31 extends out of the second surface 23 of the base 2, and the second terminal 32 extends out of the first surface 22 of the base 2. Of course, in other embodiments, the two can be interchanged.

[0037] like Figures 3 to 5 As shown, both the first terminal 31 and the second terminal 32 are stamped from metal sheets. The first terminal 31 and the second terminal 32 are slidably mounted to each other. This arrangement helps avoid the need for additional stamping dies, reducing stamping costs. The elastic element 33 is housed within the second terminal 32, which is mounted from top to bottom within the first terminal 31. The first terminal 31 is fitted over the second terminal 32 and the elastic element 33. The first terminal 31 and the second terminal 32 are mounted in the same direction in the mounting hole 21. Along the vertical direction Z, one end of the elastic element 33 elastically abuts against the first terminal 31, and the other end of the elastic element 33 elastically abuts against the second terminal 32. Figures 9 to 10 As shown, when the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, the first terminal 31 moves relative to the second terminal 32 in the vertical direction Z. In this embodiment, the elastic element 33 is a helical metal spring. In other embodiments, the elastic element 33 can be other elastic and stretchable metal parts, such as a spring sheet, leaf spring, ring spring, etc.

[0038] like Figures 3 to 7As shown, the first terminal 31 includes a hollow cylindrical body, elastic arms and elastic contact arms connected to the upper and lower sides of the cylindrical body respectively, a limiting groove 314, a limiting portion protruding from the cylindrical body, and a slit extending vertically along it.

The limiting groove 314 is located on the side of the first slit 316 away from the first guide portion 3131. The limiting groove 314 extends vertically and penetrates the insertion end of the first cylinder 311 for inserting the second terminal 32, and the limiting groove 314 communicates with the first slit 316 in the vertical direction Z. Two first elastic arms 312 are provided and extend vertically in the vertical direction Z. Each first abutting portion 3121 is provided on the corresponding first elastic arm 312, and abuts against the second terminal 32 in the first direction Y. A first guide portion 3131 is provided on the first elastic contact arm 313, and is used to guide the second mating member 300 in the vertical direction Z.

[0039] like Figures 3 to 7As shown, the second terminal 32 includes a hollow cylindrical body, elastic arms and elastic contact arms connected to the upper and lower sides of the cylindrical body respectively, a limiting portion protruding from the cylindrical body, and a slit extending vertically along it.

The first cylindrical body 311 is sleeved outside the second cylindrical body 321. The insertion end of the first cylindrical body 311 is for the second cylindrical body 321 to be inserted, facilitating the mutual installation of the first cylindrical body 311 and the second cylindrical body 321 in the vertical direction Z. The elastic member 33 is housed in the second cylindrical body 321. In the vertical direction Z, one end of the elastic member 33 elastically abuts against the first elastic contact arm 313, and the other end of the elastic member 33 elastically abuts against the second elastic contact arm 323. A second guiding part 3231 is provided on the second elastic contact arm 323 for guiding with the first mating member 200. Two second elastic arms 322 are provided and extend in the vertical direction Z. Each second abutting part 3221 is provided on the corresponding second elastic arm 322. The height d2 of the first elastic contact arm 323 in the vertical direction Z is more than half of the height d1 of the first elastic arm 312 in the vertical direction Z, and the height of the first elastic contact arm 313 in the vertical direction Z is less than the height of the second elastic arm 322 in the vertical direction Z.

[0040] like Figure 10 and Figure 12As shown, after the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, that is, after the first terminal 31 and the second terminal 32 move relative to each other in the vertical direction Z, along the first direction Y, the first abutting portion 3121 and the second elastic contact arm 323 of the first elastic arm 312 abut against each other, and the second abutting portion 3221 of the second elastic arm 322 and the first elastic contact arm 313 abut against each other.

The first abutting portion 3121 to the second... The distance d3 between the abutting part 3221 and the abutting point of the first terminal 31 exceeds half of the height d4 of the first terminal 31 in the vertical direction Z, and exceeds half of the height d5 of the second terminal 32 in the vertical direction Z. Viewed from the first direction Y, the connection point of the second cylinder 321 and the second elastic contact arm 323, the abutting point of the first abutting part 3121 and the second terminal 32, the abutting point of the second abutting part 3221 and the first terminal 31, and the connection point of the first cylinder 311 and the first elastic contact arm 313 are vertically aligned, and the abutting point of the first abutting part 3121 and the second elastic contact arm 323 is vertically aligned with the abutting point of the second abutting part 3221 and the first elastic contact arm 313. In other embodiments, the first terminal 31 does not have a first elastic arm 312, and the first abutment portion 3121 is directly disposed on the first cylinder 311. The second cylinder 321 has a protrusion protruding towards the first cylinder 311. Along the vertical direction Z, the distance from the end edge of the protrusion near the second guide portion 3231 to the end edge of the second cylinder 321 near the second guide portion 3231 is less than the thickness of the second cylinder 321. After the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, along the first direction Y, the first abutment portion 3121 and the protrusion abut against each other. Viewed from the first direction Y, the connection between the second cylinder 321 and the second elastic contact arm 323, the abutment between the first abutment portion 3121 and the second terminal 32, the abutment between the second abutment portion 3221 and the first terminal 31, and the connection between the first cylinder 311 and the first elastic contact arm 313 are vertically aligned. Of course, in some other embodiments, the first terminal 31 does not have a first elastic arm 312, and the first abutting part 3121 is directly provided on the first cylinder 311. The first abutting part 3121 is a protrusion protruding toward the second cylinder 321. Along the vertical direction Z, the distance from the end edge of the protrusion near the second guide part 3231 to the end edge of the first cylinder 311 near the second guide part 3231 is less than the thickness of the first cylinder 311.After the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, along the first direction Y, the first abutting part 3121 abuts against the second cylinder 321. And from the first direction Y, the connection between the second cylinder 321 and the second elastic contact arm 323, the abutting part between the first abutting part 3121 and the second terminal 32, the abutting part between the second abutting part 3221 and the first terminal 31, and the connection between the first cylinder 311 and the first elastic contact arm 313 are aligned vertically.

[0041] like Figures 14 to 21 As shown, in other embodiments, the second terminal 32 does not have a second elastic arm 322, and the second abutment portion 3221 is directly disposed on the second cylinder 321, that is, the second abutment portion 3221 is part of the cylinder wall of the second cylinder 321. The first cylinder 311 is provided with a plurality of protrusions 3111 protruding toward the second cylinder 321. The plurality of protrusions 3111 are spaced apart from each other. After the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, along the first direction Y, the second abutment portion 3221 abuts against the plurality of protrusions 3111. The position where the plurality of protrusions 3111 abut against the second cylinder 321 is the second abutment portion 3221. Figure 17 and Figure 21 As shown, along the vertical direction Z, the distance from the end edge of the protrusion 3111 near the first guide portion 3131 to the end edge of the first cylinder 311 near the first guide portion 3131 is less than the thickness of the first cylinder 311. Figures 14 to 17As shown, along the vertical direction Z, a portion of the protrusion 3111 is located on the first elastic contact arm 313. After the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, viewed from the first direction Y, the connection between the second cylinder 321 and the second elastic contact arm 323, the abutment of the first abutment portion 3121 of the first elastic arm 312 and the abutment of the second elastic contact arm 323, the abutment of the second abutment portion 3221 and the protrusion 3111, and the connection between the first cylinder 311 and the first elastic contact arm 313 are vertically aligned. Of course, in some other embodiments, the second terminal 32 does not have a second elastic arm 322, and the second abutment portion 3221 is directly provided on the second cylinder 321. The second abutment portion 3221 is a protrusion protruding toward the first cylinder 311. Along the vertical direction Z, the distance from the end edge of the second abutment portion 3221 near the first guide portion 3131 to the end edge of the second cylinder 321 near the first guide portion 3131 is less than the thickness of the second cylinder 321. After the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, along the first direction Y, the second abutting part 3221 abuts against the first cylinder 311. And from the first direction Y, the connection between the second cylinder 321 and the second elastic contact arm 323, the abutting part between the first abutting part 3121 and the second terminal 32, the abutting part between the second abutting part 3221 and the first terminal 31, and the connection between the first cylinder 311 and the first elastic contact arm 313 are aligned vertically.

[0042] like Figure 4 As shown, the second slit 325 is formed by the unclosed gap between the two circumferential ends of the second cylinder 321. The second slit 325 is located on the side of the first cylinder 311 facing away from the first slit 316 in the circumferential direction. The second limiting part 324 is slidably accommodated in the limiting groove 314. Specifically, the limiting groove 314 includes two opposing wall parts N. After the second guide part 3231 abuts against the first docking member 200, the second limiting part 324 is located between the two wall parts N of the limiting groove 314. The two wall parts N of the limiting groove 314 can prevent the second limiting part 324 from moving circumferentially.

[0043] like Figure 3 and 4As shown, both the first elastic contact arm 313 and the second elastic contact arm 323 include two arms (unlabeled). The first cylinder 311 connects to the two arms of the first elastic contact arm 313 at the same end in the vertical direction Z. The portions of the two arms connected to the first cylinder 311 are spaced apart, and the two arms of the same first terminal 31 are positioned opposite each other in the first direction Y at their connection points with the first cylinder 311. The second cylinder 321 connects to the two arms of the second elastic contact arm 323 at the same end in the vertical direction Z. The portions of the two arms connected to the second cylinder 321 are spaced apart, and the two arms of the same second terminal 32 are positioned opposite each other in the first direction Y at their connection points with the second cylinder 321. Along the vertical direction Z, one end of the elastic member 33 elastically abuts against the two arms of the first elastic contact arm 313, and the other end of the elastic member 33 elastically abuts against the two arms of the second elastic contact arm 323. After the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, the two first elastic arms 312 of the same first terminal 31 are arranged opposite each other along the first direction Y, and the two first abutting portions 3121 abut against the two arms of the second terminal 32 respectively. The two second elastic arms 322 of the same second terminal 32 are arranged opposite each other along the first direction Y, and the two second abutting portions 3221 abut against the two arms of the first terminal 31 respectively. In other embodiments, the first elastic contact arm 313 may only include two arms, and the second guiding portion 3231 abuts against the first mating member 200 through a structure of other shapes; or the second elastic contact arm 323 may only include two arms, and the first guiding portion 3131 abuts against the second mating member 300 through a structure of other shapes.

[0044] like Figure 3 and Figure 4As shown, the two arms of the first elastic contact arm 313 and the two arms of the second elastic contact arm 323 are respectively the first arm S1 and the second arm S2. In this embodiment, the first guide portion 3131 is disposed on the first arm S1 of the first elastic contact arm 313 and elastically abuts against the second docking member 300. The second guide portion 3231 is disposed on the first arm S1 of the second elastic contact arm 323 and elastically abuts against the first docking member 200. In other embodiments, the first guide portion 3131 may be disposed on both the first arm S1 and the second arm S2 of the first elastic contact arm 313, and the second guide portion 3231 may be disposed on both the first arm S1 and the second arm S2 of the second elastic contact arm 323. The second arm S2 of the first terminal 31 is closer to the second guide portion 3231 relative to the first guide portion 3131, and the second arm S2 of the second terminal 32 is closer to the first guide portion 3131 relative to the second guide portion 3231. When the first guide portion 3131 elastically abuts against the second mating member 300 and the second guide portion 3231 elastically abuts against the first mating member 200, along the vertical direction Z, the second cylinder 321 extends beyond the first cylinder 311 towards the end near the first guide portion 3131 and covers the portion between the two arms, that is, the second cylinder 321 extends downward beyond the first cylinder 311 and covers the portion between the first arm S1 and the second arm S2.

[0045] like Figure 7As shown, the first arm S1 includes a first connecting segment S11 and a first extension segment S12 that bends and extends from the first connecting segment S11. The second arm S2 includes a second connecting segment S21 and a second extension segment S22 that bends and extends from the second connecting segment S21. The first connecting segment S11 and the second connecting segment S21 of the first elastic contact arm 313 are jointly connected to the first cylinder 311. The first cylinder 311 is connected to the first connecting segment S11 and the second connecting segment S21 of the first elastic contact arm 313 at the same end in the vertical direction Z. The first connecting segment S11 and the second connecting segment S21 of the second elastic contact arm 323 are jointly connected to the second cylinder 321. The second cylinder 321 is connected to the first connecting segment S11 and the second connecting segment S21 of the second elastic contact arm 323 at the same end in the vertical direction Z. The first connecting segment S11 and the second connecting segment S21 of the first terminal 31 are opposite to each other and spaced apart along the first direction Y. The first connecting segment S11 and the second connecting segment S21 of the second terminal 32 are opposite to each other and spaced apart along the first direction Y. Along the first direction Y, the length of the first extension segment S12 is greater than the length of the second extension segment S22. Along the vertical direction Z, the first extension segment S12 and the second extension segment S22 of the same first terminal 31 abut against each other, and the first extension segment S12 and the second extension segment S22 of the same second terminal 32 abut against each other. Specifically, the first extension segment S12 of the first terminal 31 is located below the second extension segment S22, and the first extension segment S12 of the second terminal 32 is located above the second extension segment S22. Along the first direction Y, the abutment position of the first extension segment S12 and the second extension segment S22 is closer to the second connecting segment S21 than the first connecting segment S11. Along the vertical direction Z, the first extension segment S12 and the second extension segment S22 of the first terminal 31 elastically abut against one end of the elastic member 33, and the first extension segment S12 and the second extension segment S22 of the second terminal 32 elastically abut against the other end of the elastic member 33. The first guide portion 3131 is provided on the first extension S12 of the first elastic contact arm 313, and the second guide portion 3231 is provided on the first extension S12 of the second elastic contact arm 323. The first guide portion 3131 is offset from the center line P of the width of the first cylinder 311 in the vertical direction Z, and the second guide portion 3231 is offset from the center line P of the width of the second cylinder 321 in the vertical direction Z. This arrangement is beneficial to the elastic member 33 being able to twist after being compressed by force. After twisting, the elastic member 33 forms a "C" shape roughly along the vertical direction Z, thereby making multiple points of contact with the first terminal 31 and the second terminal 32.

[0046] like Figures 12 to 13As shown, the first terminal 31 and the second terminal 32 are both installed from bottom to top in the mounting hole 21. The first limiting part 315 passes over the first stop part 24 and enters between the two walls M of the first guide groove 26. The two walls M of the first guide groove 26 can prevent the first limiting part 315 from moving circumferentially. The second limiting part 324 enters between the two walls M of the second guide groove 27. The two walls M of the second guide groove 27 can prevent the second limiting part 324 from moving circumferentially. The first limiting part 315 is used to engage with the first stop part 24 in the vertical direction Z, and the second limiting part 324 is used to engage with the second stop part 25 in the vertical direction Z. The first limiting part 315 and the second limiting part 324 are located between the first stop part 24 and the second stop part 25 in the vertical direction Z. Specifically, before the first terminal 31 abuts against the second mating member 300 and before the second terminal 32 abuts against the first mating member 200, the first stop portion 24 abuts against the first limiting portion 315 upwards to prevent the first limiting portion 315 from moving downwards, and the second stop portion 25 abuts against the second limiting portion 324 downwards to prevent the second limiting portion 324 from moving upwards.

[0047] like Figures 22 to 28 As shown in the second embodiment of the present invention, the conductive terminal 3 is one of a pair of differential signal terminals. The conductive terminal 3 includes a first terminal 31, a second terminal 32 and an elastic member 33. The first terminal 31 is used to abut against the second mating member 300, the second terminal 32 is used to abut against the first mating member 200, and the elastic member 33 is located between the first terminal 31 and the second terminal 32 and is electrically connected to the first terminal 31 and the second terminal 32.

[0048] like Figure 22 As shown, both the first terminal 31 and the second terminal 32 are stamped from sheet metal. The first terminal 31 and the second terminal 32 are slidably mounted relative to each other. This arrangement helps avoid the need for additional stamping dies, reducing stamping costs. The elastic element 33 is housed within the second terminal 32, which is mounted from top to bottom within the first terminal 31. The first terminal 31 is sleeved around the second terminal 32 and the elastic element 33. Along the vertical Z-direction, one end of the elastic element 33 elastically abuts against the first terminal 31, and the other end elastically abuts against the second terminal 32. Figures 25 to 28 As shown, when the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, the first terminal 31 moves relative to the second terminal 32 in the vertical direction Z. In this embodiment, the elastic element 33 is a helical metal spring. In other embodiments, the elastic element 33 can be other elastic and stretchable metal parts, such as a spring sheet, leaf spring, ring spring, etc.

[0049] like Figure 23 and Figure 24As shown, the first terminal 31 includes a hollow cylindrical body, connecting portions and elastic contact arms integrally connected to the upper and lower sides of the cylindrical body, an elastic arm integrally connected to the connecting portion, a limiting groove 314, a limiting portion protruding from the cylindrical body, and a slit extending vertically along it. The cylindrical body of the first terminal 31 is defined as the first cylindrical body 311, the elastic arm as the first elastic arm 312, the elastic contact arm as the first elastic contact arm 313, the limiting portion as the first limiting portion 315, the slit as the first slit 316, and the connecting portion as the first connecting portion 317. In this embodiment, the first cylindrical body 311 is cylindrical; in other embodiments, the first cylindrical body 311 can be a square cylinder or a cylindrical body of other shapes. Both the limiting groove 314 and the first slit 316 are formed by the unclosed gap between the two circumferential ends of the first cylindrical body 311, and the circumferential width of the limiting groove 314 is greater than the circumferential width of the first slit 316. The limiting groove 314 is located on the side of the first slit 316 away from the first guide portion 3131. The limiting groove 314 extends along the vertical direction Z and penetrates the insertion end of the first cylindrical body 311 for inserting the second terminal 32, and the limiting groove 314 communicates with the first slit 316 in the vertical direction Z. Two first elastic arms 312 are provided, and each first abutting portion 3121 is respectively provided on the corresponding first elastic arm 312. Along the first direction Y, the first abutting portion 3121 abuts against the second terminal 32. The first connecting portion 317 and the two first elastic arms 312 form a cylindrical shape. The circumferential width of each first elastic arm 312 is greater than the circumferential width of the first connecting portion 317. When the size of the first terminal 31 is limited, it is beneficial to increase the arm length of the two first elastic arms 312 and improve elasticity. The ends of the two first elastic arms 312 are opposite to each other and spaced apart. A first guide portion 3131 is provided on the first elastic contact arm 313 along the vertical direction Z, and the first guide portion 3131 is used to guide with the second mating member 300.

[0050] like Figure 23 and Figure 24As shown, the second terminal 32 includes a hollow cylindrical body, connecting portions and elastic contact arms respectively connecting the upper and lower sides of the cylindrical body, an elastic arm integrally connected to the connecting portions, a limiting portion protruding from the cylindrical body, and a slit extending vertically along it. The cylindrical body of the second terminal 32 is defined as the second cylindrical body 321, the elastic arm as the second elastic arm 322, the elastic contact arm as the second elastic contact arm 323, the limiting portion as the second limiting portion 324, the slit as the second slit 325, and the connecting portion as the second connecting portion 326. In this embodiment, the second cylindrical body 321 is cylindrical; in other embodiments, the second cylindrical body 321 can be a square cylinder or a cylindrical body of other shapes. The first cylindrical body 311 is sleeved outside the second cylindrical body 321. The insertion end of the first cylindrical body 311 allows the second cylindrical body 321 to be inserted, facilitating the mutual installation of the first and second cylindrical bodies 311 and 321 in the vertical direction Z. The elastic member 33 is housed within the second cylindrical body 321. In the vertical direction Z, one end of the elastic member 33 elastically abuts against the first elastic contact arm 313, and the other end of the elastic member 33 elastically abuts against the second elastic contact arm 323. A second guiding part 3231 is provided on the second elastic contact arm 323 for guiding with the first mating member 200. The second connecting part 326 and the two second elastic arms 322 form a cylindrical shape. The circumferential width of each second elastic arm 322 is greater than the circumferential width of the second connecting part 326. Given the limited size of the first terminal 32, this allows for an increase in the arm length of the two second elastic arms 322, improving elasticity. The ends of the two second elastic arms 322 are opposite to each other and spaced apart. Two second elastic arms 322 are provided, and each second abutment portion 3221 is respectively provided on the corresponding second elastic arm 322. The second slit 325 is formed by the unclosed gap between the two circumferential ends of the second cylinder 321, and the second slit 325 is located on the side of the first cylinder 311 facing the first slit 316 circumferentially. The second limiting portion 324 is slidably accommodated in the limiting groove 314, and the limiting groove 314 includes a limiting wall T. The limiting wall T is located on the side of the second limiting portion 324 away from the first guide portion 3131. The limiting wall T blocks the second limiting portion 324 from displacing away from the first guide portion 3131 in the vertical direction Z. The gap between the ends of the two first elastic arms 312 communicates with the first slit 316 in the vertical direction Z.

[0051] like Figure 23 and Figure 24As shown, both the first elastic arm 312 and the second elastic arm 322 include a first elastic segment L1 extending on a horizontal plane and a second elastic segment L2 extending from the first elastic segment L1 in the vertical direction Z toward the first conductive portion 3131. The first elastic segment L1 of the first elastic arm 312 is integrally connected to the first connecting portion 317, and the lower edge of the first elastic segment L1 of the first elastic arm 312 is flush with the lower edge of the first connecting portion 317. The first abutment portion 3121 is provided at the end of the second elastic segment L2 of the first elastic arm 312, which can effectively suppress the antenna effect. The first elastic segment L1 of the second elastic arm 322 is integrally connected to the second connecting portion 326, and the upper edge of the first elastic segment L1 of the second elastic arm 322 is flush with the upper edge of the second connecting portion 326. The second abutment portion 3221 is provided at the end of the second elastic segment L2 of the second elastic arm 322, which can effectively suppress the antenna effect.

[0052] like Figures 21 to 23 As shown, both the first elastic contact arm 313 and the second elastic contact arm 323 include two arms (unlabeled). The first cylinder 311 connects to the two arms of the first elastic contact arm 313 at the same end in the vertical direction Z. The portions of the two arms connected to the first cylinder 311 are spaced apart, and the two arms of the same first terminal 31 are positioned opposite each other in the first direction Y at their connection points with the first cylinder 311. The second cylinder 321 connects to the two arms of the second elastic contact arm 323 at the same end in the vertical direction Z. The portions of the two arms connected to the second cylinder 321 are spaced apart, and the two arms of the same second terminal 32 are positioned opposite each other in the first direction Y at their connection points with the second cylinder 321. Along the vertical direction Z, one end of the elastic member 33 elastically abuts against the two arms of the first elastic contact arm 313, and the other end of the elastic member 33 elastically abuts against the two arms of the second elastic contact arm 323. In other embodiments, the first elastic contact arm 313 may consist of two arms, and the second guide portion 3231 may abut against the first docking member 200 through a structure of other shapes. Alternatively, the second elastic contact arm 323 may consist of two arms, and the first guide portion 3131 may abut against the second docking member 300 through a structure of other shapes.

[0053] like Figures 21 to 23As shown, the two arms of the first elastic contact arm 313 and the two arms of the second elastic contact arm 323 are respectively the first arm S1 and the second arm S2. In this embodiment, the first guide portion 3131 is disposed on the first arm S1 of the first elastic contact arm 313 and elastically abuts against the second docking member 300. The second guide portion 3231 is disposed on the first arm S1 of the second elastic contact arm 323 and elastically abuts against the first docking member 200. In other embodiments, the first guide portion 3131 may be disposed on both the first arm S1 and the second arm S2 of the first elastic contact arm 313, and the second guide portion 3231 may be disposed on both the first arm S1 and the second arm S2 of the second elastic contact arm 323. The second arm S2 of the first terminal 31 is closer to the second conductor 3231 relative to the first conductor 3131, and the second arm S2 of the second terminal 32 is closer to the first conductor 3131 relative to the second conductor 3231.

[0054] like Figures 21 to 23As shown, the first arm S1 includes a first connecting segment S11 and a first extension segment S12 that bends and extends from the first connecting segment S11. The second arm S2 includes a second connecting segment S21 and a second extension segment S22 that bends and extends from the second connecting segment S21. The first connecting segment S11 and the second connecting segment S21 of the first elastic contact arm 313 are jointly connected to the first cylinder 311, and the first cylinder 311 is connected to the first connecting segment S11 and the second connecting segment S21 of the first elastic contact arm 313 at the same end in the vertical direction Z; the first connecting segment S11 and the second connecting segment S21 of the second elastic contact arm 323 are jointly connected to the second cylinder 321, and the second cylinder 321 is connected to the first connecting segment S11 and the second connecting segment S21 of the second elastic contact arm 323 at the same end in the vertical direction Z. The first connecting segment S11 and the second connecting segment S21 of the first terminal 31 are arranged opposite to each other and spaced apart along the first direction Y, and the first connecting segment S11 and the second connecting segment S21 of the second terminal 32 are arranged opposite to each other and spaced apart along the first direction Y. Along the first direction Y, the length of the first extension segment S12 is greater than the length of the second extension segment S22. Along the vertical direction Z, the first extension segment S12 and the second extension segment S22 of the same first terminal 31 abut against each other, and the first extension segment S12 and the second extension segment S22 of the same second terminal 32 abut against each other. Specifically, the first extension segment S12 of the first terminal 31 is located below the second extension segment S22, and the first extension segment S12 of the second terminal 32 is located above the second extension segment S22. Along the first direction Y, the abutment position of the first extension segment S12 and the second extension segment S22 is closer to the second connecting segment S21 than the first connecting segment S11. Along the vertical direction Z, the first extension segment S12 and the second extension segment S22 of the first terminal 31 elastically abut against one end of the elastic member 33, and the first extension segment S12 and the second extension segment S22 of the second terminal 32 elastically abut against the other end of the elastic member 33. The first guide portion 3131 is provided on the first extension S12 of the first elastic contact arm 313, and the second guide portion 3231 is provided on the first extension S12 of the second elastic contact arm 323. The first guide portion 3131 is offset from the center line P of the width of the first cylinder 311 in the vertical direction Z, and the second guide portion 3231 is offset from the center line P of the width of the second cylinder 321 in the vertical direction Z. This arrangement is beneficial to the elastic member 33 being able to twist after being compressed by force. After twisting, the elastic member 33 forms a "C" shape roughly along the vertical direction Z, thereby making multiple points of contact with the first terminal 31 and the second terminal 32.

[0055] like Figures 25 to 28As shown, after the first terminal 31 is connected to the second mating member 300 and the second terminal 32 is connected to the first mating member 200, that is, after the first terminal 31 and the second terminal 32 move relative to each other in the vertical direction Z and the first connecting part 3131 is connected to the second mating member 300 and the second connecting part 3231 is connected to the first mating member 200, along the first direction Y, the first abutting part 3121 of the first elastic arm 312 and the second cylinder 321 abut against each other, and the second abutting part 3221 of the second elastic arm 322 and the first cylinder 311 abut against each other. Along the vertical direction Z, the first abutting part 3121 is closer to the second connecting part 3231 than the first connecting part 3131, and the second abutting part 3221 is closer to the first connecting part 3131 than the second connecting part 3231. The distance d3 from the contact portion 3121 to the contact point between the second contact portion 3221 and the first terminal 31 exceeds half of the height d4 of the first terminal 31 in the vertical direction Z, and exceeds half of the height d5 of the second terminal 32 in the vertical direction Z. Along the vertical direction Z, a portion of the first elastic contact arm 313 is located between the two first elastic arms 312 of the first terminal 31, and a portion of the second elastic contact arm 323 is located between the two second elastic arms 322 of the second terminal 32. Along the vertical direction Z, the second cylinder 321 extends beyond the first cylinder 311 towards the end near the first guide portion 3131 and covers the portion of the two arms that are spaced apart from each other, that is, the second cylinder 321 extends downward beyond the first cylinder 311 and covers the portion of the first arm S1 and the second arm S2 that are spaced apart from each other.

[0056] The beneficial effects of this invention are as follows: 1. After the first terminal 31 and the second terminal 32 move relative to each other in the vertical direction Z, the first abutting part 3121 abuts against the second terminal 32, and the second abutting part 3221 abuts against the first terminal 31. This not only ensures that the abutting positions of the first terminal 31 and the second terminal 32 are the same each time, and that the transmission path is the same, but also allows the current between the first mating element and the second mating element to be transmitted through the first conductive part 3131, the abutting part 3221 and the abutting point of the first terminal 31, the abutting point of the first abutting part 3121 and the second terminal 32, and the second conductive part 3231, without relying on the elastic member 33 for current transmission. This shortens the current transmission path, and the second abutting part 3221 abuts against the first terminal 31 and the first abutting part 3121. The first abutment portion 3121 and the second abutment portion 32 can jointly realize dual-channel path transmission of the first terminal 31 and the second terminal 32, thereby improving the transmission rate. Furthermore, along the vertical direction Z, the first abutment portion 3121 is closer to the second guide portion 3231 than the first guide portion 3131, and the second abutment portion 3221 is closer to the first guide portion 3131 than the second guide portion 3231. The distance d3 from the first abutment portion 3121 to the abutment point of the second abutment portion 3221 and the first terminal 31 exceeds half of the height d4 of the first terminal 31 in the vertical direction Z, and exceeds half of the height d5 of the second terminal 32 in the vertical direction Z. This is beneficial to increase the length of the dual-channel path transmission of the first terminal 31 and the second terminal 32, thereby further improving the transmission rate.

[0057] 2. The second conductive part 3231 is disposed on the second elastic contact arm 323. The first abutting part 3121 abuts against the second elastic contact arm 323. Compared with the first abutting part 3121 abutting against the second cylinder 321, this is beneficial to shorten the current transmission path from the first abutting part 3121 to the second conductive part 3231, increase the length of the dual-channel transmission path between the first terminal 31 and the second terminal 32, and further improve the transmission rate. On this basis, the height d2 of the second elastic contact arm 323 in the vertical direction Z is smaller than that of the first elastic arm 312 in the vertical direction Z. The height d1 in the downward direction Z is more than half of the height d1. Since the first elastic arm 312 is longer than the second elastic contact arm 323, it has better elasticity and less holding force, which helps to reduce the force applied by the first docking member 200 and the second docking member 300 to push the first terminal 31 to move relative to the second terminal 32 in the vertical direction Z. The second elastic contact arm 323 is shorter than the first elastic arm 312, which helps to reduce the deformation of the second elastic contact arm 323 at the position where it is abutted by the first abutting part 3121, thus ensuring stable contact between the first terminal 31 and the second terminal 32.

[0058] 3. The second conductive part 3231 is disposed on at least one of the two arms of the second elastic contact arm 323. The two first abutting parts 3121 abut against the two arms of the second elastic contact arm 323 respectively. Compared with the first abutting part 3121 abutting against the second cylinder 321, it is beneficial to shorten the current transmission path from the first abutting part 3121 to the second conductive part 3231, increase the length of the dual-channel transmission path of the first terminal 31 and the second terminal 32, and further improve the transmission rate. On this basis, the two arms of the second elastic contact arm 323 are arranged opposite to each other at the connection with the second cylinder 321 along a first direction Y, wherein the two first elastic arms 312 are arranged opposite to each other along the first direction Y, and the two first abutting parts 3121 abut against the two arms of the second elastic contact arm 323 respectively. This is beneficial to the uniform force when the two first elastic arms 312 abut against the two arms, ensuring the stability of the abutment and avoiding poor contact due to the relative misalignment of the first terminal 31 and the second terminal 32.

[0059] 4. The first conductive part 3131 is disposed on at least one of the two arms of the first elastic contact arm 313. The two second abutting parts 3221 abut against the two arms of the first elastic contact arm 313 respectively. Compared with the second abutting part 3221 abutting against the first cylinder 311, it is beneficial to shorten the current transmission path from the second abutting part 3221 to the first conductive part 3131, increase the length of the dual-channel transmission path of the first terminal 31 and the second terminal 32, and further improve the transmission rate. On this basis, the two arms of the first elastic contact arm 313 are arranged opposite to the first cylinder 311 at the connection point along a first direction Y, wherein the two second elastic arms 322 are arranged opposite to each other along the first direction Y, and the two second abutting parts 3221 abut against the two arms of the first elastic contact arm 313 respectively. This is beneficial to the uniform force when the two second elastic arms 322 abut against the two arms of the first elastic contact arm 313, ensuring the stability of the abutment and avoiding poor contact due to the relative misalignment of the first terminal 31 and the second terminal 32.

[0060] 5. The first conductive portion 3131 is disposed on the first elastic contact arm 313, and the second abutting portion 3221 abuts against the second elastic contact arm 323. Compared with the second abutting portion 3221 abutting against the first cylinder 311, this is beneficial to shorten the current transmission path from the first abutting portion 3121 to the second conductive portion 3231, increase the length of the dual-channel transmission path between the first terminal 31 and the second terminal 32, and further improve the transmission rate. The second conductive portion 3231 is disposed on the second elastic contact arm 323, and the first abutting portion 3121 abuts against the second elastic contact arm 323. Compared to the first abutting part 3121 abutting the second cylinder 321, it is beneficial to shorten the current transmission path from the first abutting part 3121 to the second conductive part 3231, increase the length of the dual-channel transmission path of the first terminal 31 and the second terminal 32, and further improve the transmission rate. On this basis, from the first direction Y, the abutting point of the first abutting part 3121 and the second elastic contact arm 323 are aligned vertically with the abutting point of the second abutting part 3221 and the first elastic contact arm 313. Since the straight distance is the shortest transmission path, the transmission rate is further improved.

[0061] 6. The first cylindrical body 311 abuts against the second abutting part 3221 through multiple protrusions 3111 protruding towards the second cylindrical body 321. The abutment between the two is stable, and the protrusions 3111 are simple to form. The multiple protrusions 3111 are spaced apart from each other, which can avoid the excessive abutting force between the protrusions 3111 and the second abutting part 3221, which would make it difficult for the second docking member 300 to push the first terminal 31 or for the first docking member 200 to push the second terminal 32. The part of the protrusions 3111 near the first conductive part 3131 to the end edge of the first cylindrical body 311 near the first conductive part 3131 is prone to antenna effect. By making the distance along the vertical direction Z from the end edge of the protrusions 3111 near the first conductive part 3131 to the end edge of the first cylindrical body 311 near the first conductive part 3131 less than the thickness of the first cylindrical body 311, the antenna effect can be effectively suppressed.

[0062] 7. The direction in which the first abutting part 3121 and the second terminal 32 abut against each other is the same as the direction in which the second abutting part 3221 and the first terminal 31 abut against each other. The direction in which the first abutting part 3121 and the second terminal 32 abut against each other is defined as the first direction Y. From the first direction Y, the connection between the second cylinder 321 and the second elastic contact arm 323, the abutting part between the first abutting part 3121 and the second terminal 32, the abutting part between the second abutting part 3221 and the first terminal 31, and the connection between the first cylinder 311 and the first elastic contact arm 313 are aligned vertically. Since the straight distance is the shortest transmission path, the transmission rate is further improved.

[0063] 8. At least one of the first terminal 31 and the second terminal 32 includes two arms, namely a first arm S1 and a second arm S2. A first conductive portion 3131 is disposed on the first arm S1 of the first terminal 31 and / or a second conductive portion 3231 is disposed on the first arm S1 of the second terminal 32. Compared to having the first conductive portion 3131 and the second arm S2 simultaneously disposed on both the first arm S1 and the second arm S2, and / or the second conductive portion 3231 and the second arm S2 simultaneously disposed on both the first arm S1 and the second arm S2, this avoids the situation where, due to manufacturing tolerances, one of the first arm S1 and the second arm S2 fails to abut against the first arm S1. A first mating member 200 and / or a second mating member 300; along the vertical direction Z, the first arm S1 abuts against the second arm S2, the second arm S2 of the first terminal 31 is closer to the second conductive part 3231 relative to the first conductive part 3131, and / or the second arm S2 of the second terminal 32 is closer to the first conductive part 3131 relative to the second conductive part 3231. This achieves dual-channel transmission of current from the first conductive part 3131 and / or the second conductive part 3231 through the first arm S1 and the second arm S2 respectively, and also ensures that the first mating member 200 abuts against the second conductive part 3231 and / or the second conductive part 3231. When the mating part 300 abuts against the first conductive part 3131, the second arm S2 provides support for the first arm S1, increasing the holding force of the first arm S1 against the first mating part 200 and / or the second mating part 300. This arrangement creates a height difference between the first arm S1 and the second arm S2 at the point where they abut against the elastic member 33, which facilitates the twisting of the elastic member 33 after compression. The twisted elastic member 33 forms a roughly Z-shaped "C" along the vertical direction, resulting in multiple points of contact with the first terminal 31 and the second terminal 32. Because the conductive terminal 3, after assembly, connects with the first mating part 200... Before the second mating member 300 abuts, the elastic member 33 will have a pre-pressure on the first terminal 31 and the second terminal 32. Compared with one of the first arm S1 and the second arm S2 elastically abutting one end of the elastic member 33, by setting the first arm S1 and the second arm S2 of the first terminal 31 to elastically abut one end of the elastic member 33 together along the vertical direction Z, and / or the first arm S1 and the second arm S2 of the second terminal 32 to elastically abut the other end of the elastic member 33 together, it can prevent the elastic member 33 from opening one of the first arm S1 and the second arm S2 during vertical movement and causing excessive deformation.

[0064] 9. The second connecting segment S21 connects the first cylinder 311 and / or the second cylinder 321. The first connecting segment S11 and the second connecting segment S21 of the first terminal 31 are arranged opposite each other along a first direction Y, and / or the first connecting segment S11 and the second connecting segment S21 of the second terminal 32 are arranged opposite each other along the first direction Y. This facilitates the first connecting segment S11 and the second connecting segment S21 in the first direction Y to limit the torsional displacement of the elastic member 33 when the first extension segment S12 and the second extension segment S22 elastically abut against the elastic member 33 together, making it difficult for the two ends of the elastic member 33 to come out. In the vertical direction Z, the first extension segment S12 and the second extension segment S22 of the first terminal 31 abut against each other, and / or the first extension segment S12 and the second extension segment S22 of the second terminal 32 abut against each other. The length of the first extension segment S12 is greater than that of the second extension segment S22. The length, along the first direction Y, the contact position of the first extension segment S12 and the second extension segment S22 is closer to the second connecting segment S21 than the first connecting segment S11. This is beneficial for the second connecting segment S21 to provide support for the second extension segment S22, increasing the strength of the first extension segment S12 under pressure, making the first extension segment S12 less prone to deformation under pressure. The first guide part 3131 is set off from the center line P of the defined width of the first cylinder 311 in the vertical direction Z, and / or the second guide part 3231 is set off from the center line of the defined width of the second cylinder 321 in the vertical direction Z. This setting is beneficial for the elastic element 33 to be able to twist after being compressed. After twisting, the elastic element 33 forms a roughly "C" shape along the vertical direction Z, thus having multiple points of contact with the first terminal 31 and the second terminal 32.

[0065] 10. The first terminal 31 includes a hollow first cylindrical body 311 and a first elastic contact arm 313 connecting the first cylindrical body 311. The first elastic contact arm 313 includes two arm portions, and a first guiding portion 3131 is disposed on at least one of the two arm portions. By setting the portions of the two arm portions that are respectively connected to the first cylindrical body 311 to be spaced apart from each other, the first guiding portion 3131 and the second mating member 300 can be better elastically abutted. Along the vertical direction Z, the elastic member 33 elastically abuts against the two arm portions, and the elastic member 33 extends out of the first cylindrical body 31. 1. The part surrounded by the two arms cannot effectively control the tilting of the elastic element 33 after being compressed because the parts of the two arms that are connected to the first cylinder 311 are spaced apart. By setting the first guide part 3131 to be connected to the second docking member 300 and the second guide part 3231 to be connected to the first docking member 200, the second cylinder 321 extends beyond the first cylinder 311 towards the end near the first guide part 3131 and covers the spaced-apart parts of the two arms, the tilting of the spring can be better restricted.

[0066] 11. Since both the first terminal 31 and the second terminal 32 are formed by stamping metal sheets, the first cylindrical body 311 has a first slit 316 extending vertically therefrom, which is formed by the unclosed gap between the two circumferential ends of the first cylindrical body 311. The second cylindrical body 321 has a second slit 325 extending vertically therefrom, which is formed by the unclosed gap between the two circumferential ends of the second cylindrical body 321. The second slit 325 is located on the side of the first cylindrical body 311 facing away from the first slit 316 in the circumferential direction, which is beneficial to the first slit 316 and the second slit 325. The staggered arrangement of the first and second slits 316 and 325 prevents them from interlocking or scraping against each other during relative movement, effectively reducing sliding resistance and preventing jamming. Furthermore, by placing the second slit 325 on the side of the first cylinder 311 facing away from the first slit 316 in the circumferential direction, the low-stiffness region of the first cylinder 311 and the high-stiffness region of the second cylinder 321 compensate for each other in the circumferential direction, thereby making the radial stiffness of the assembly more consistent at various angles in the circumferential direction. This avoids eccentric loads caused by stiffness asymmetry and ensures the centering accuracy and uniform force distribution during vertical movement.

[0067] 12. A limiting groove 314 extends in the vertical direction Z and penetrates the insertion end of the first cylinder 311 for inserting the second cylinder 321. A second limiting part 324 is slidably accommodated in the limiting groove 314. The limiting groove 314 includes two opposing wall portions N. After the second guide portion 3231 abuts against the first mating member 200, the second limiting part 324 is located between the two wall portions N of the limiting groove 314. The two wall portions N of the limiting groove 314 can prevent the second limiting part 324 from moving circumferentially, thus achieving foolproof assembly of the first cylinder 311 and the second cylinder 321. The second limiting part 324 and the limiting groove... The sliding fit of 314 provides precise guidance for the relative up-and-down movement of the two, preventing relative rotation. Both the limiting groove 314 and the first slit 316 are formed by the unclosed gap between the two circumferential ends of the first cylinder 311. The circumferential width of the limiting groove 314 is greater than the circumferential width of the first slit 316, and the limiting groove 314 and the first slit 316 are connected in the vertical Z direction. This means that the limiting groove 314 does not need to be drilled twice. When punching the first cylinder 311, it is only necessary to punch notches at both ends. After bending, it will automatically fit together to form the limiting groove 314, which is formed simultaneously with the first slit 316, simplifying the process.

[0068] 13. The limiting groove 314 extends in the vertical direction Z and penetrates the insertion end of the first cylinder 311 for inserting the second cylinder 321. The second limiting part 324 is slidably accommodated in the limiting groove 314. The limiting groove 314 includes two opposing wall parts N. After the second guide part 3231 abuts against the first docking member 200, the second limiting part 324 is located between the two wall parts N of the limiting groove 314. The two wall parts N of the limiting groove 314 can prevent the second limiting part 324 from moving circumferentially, which can realize the assembly of the first cylinder 311 and the second cylinder 321 without mistake. The sliding cooperation between the second limiting part 324 and the limiting groove 314 is the relative vertical movement of the two. The movement provides precise guidance to prevent relative rotation; based on this, the base 2 includes a second guide groove 27 corresponding to each mounting hole 21, a second stop 25 is provided in the second guide groove 27, and a second limiting part 324 enters between the two walls M of the second guide groove 27. The two walls M of the second guide groove 27 can prevent the second limiting part 324 from moving circumferentially. Before the second guide part 3231 abuts against the first docking member 200, the second stop 25 abuts against the second limiting part 324 downwards, preventing the second limiting part 324 from moving upwards, thus realizing that the second limiting part 324 can be limited by both the second stop 25 and the limiting groove 314.

[0069] 14. Both the first terminal 31 and the second terminal 32 include a cylindrical body. The first terminal 31 further includes a first connecting portion 317 and two first elastic arms 312. The cylindrical body of the first terminal 31 is cylindrical. The first connecting portion 317 integrally connects the cylindrical body of the first terminal 31 and the two first elastic segments L1. The first connecting portion 317 and the two first elastic arms 312 form a cylindrical shape. The second terminal 32 further includes a second elastic contact arm 323 connecting the cylindrical body of the second terminal 32. The cylindrical body of the first terminal 31 is sleeved on the cylindrical body of the second terminal 32. The elastic element 33 is housed within the second... The cylindrical body of terminal 32, along the vertical direction Z, has an elastic member 33 abutting against the second elastic contact arm 323. The second conductive part 3231 is disposed on the second elastic contact arm 323.
