Description

Technical Field

[0001] This invention relates to a conductive terminal and an electrical connector, and more particularly to a conductive terminal that improves high-frequency performance. Background Technology

[0002] An electrical connector is disclosed in the prior art, which includes a base and conductive terminals disposed on the base. The conductive terminals are connected between a first mating element and a second mating element. The conductive terminals include a first terminal and a second terminal. The second terminal and the first terminal are stacked in a first direction. A portion of the middle of the first terminal is bent in a serpentine shape along a second direction to form an elastic portion. The elastic portions of the first terminal are electrically connected to the second terminal on both sides in the second direction. The first terminal has a mating portion formed on one side of the elastic portion for mating with the first mating element. The second terminal has a receiving portion for receiving the elastic portion. The two do not form an abutment. A conductive portion is formed on one side of the receiving portion in the second direction for conducting with the second mating element.

[0003] However, in the prior art, the elastic part of the first terminal is electrically connected to the first terminal on both sides in the second direction. The signal transmission in the second direction of the first terminal needs to pass through the entire serpentine bend, resulting in a longer signal transmission path. This leads to a longer capacitive coupling path between the first terminal and the second terminal. In the crosstalk and insertion loss pattern of the conductive terminal, more resonances are generated under the specified frequency range, resulting in poor high-frequency performance of the electrical connector.

[0004] Therefore, it is necessary to design a conductive terminal and electrical connector with improved high-frequency performance to overcome the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a conductive terminal and an electrical connector, wherein a third terminal is sandwiched between a first terminal and a second terminal, and a first abutting part is provided between the second abutting part and the third abutting part of the third terminal to abut against the second terminal, thereby shortening the capacitive coupling length between the third terminal and the first and second terminals and improving the high-frequency performance of the electrical connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a conductive terminal for mating with a first mating element and a second mating element, comprising: a first terminal; a second terminal disposed opposite to the first terminal in a first direction; and a third terminal located between the first terminal and the second terminal in the first direction. The third terminal includes an elastic portion having elasticity in a second direction, wherein the second direction is perpendicular to the first direction. The elastic portion includes a first bending segment, a second bending segment, and a connecting segment. At least one of the first bending segment and the second bending segment is provided with at least two of them. The first bending segment is connected to any adjacent second bending segment via at least one of the connecting segments. The connecting segment is provided with at least one first abutment portion to abut against... The second terminal is defined in a third direction perpendicular to the first and second directions. The third terminal forms at least one second abutment on one side of the first abutment and at least one third abutment on the other side of the first abutment. The second abutment and the third abutment abut against the first terminal. At least one of the connecting segments and the corresponding first and second bent segments are provided with the first abutment, the second abutment, and the third abutment. At least one of the first terminal and the third terminal is provided with a first mating portion for mating with the first mating element. At least one of the second terminal and the third terminal is provided with a second mating portion for mating with the second mating element.

[0007] Furthermore, the elastic portion is provided with at least one of the first abutting portion, the second abutting portion, and the third abutting portion at both ends in the second direction, and the elastic portion is provided with at least one of the first abutting portion, the second abutting portion, and the third abutting portion in the middle portion between the two ends in the second direction.

[0008] Furthermore, the elastic portion is at least partially arched toward the second terminal in a first direction, thereby forming the first abutting portion at the top of the arched elastic portion to abut against the second terminal. The first bent segment correspondingly forms the second abutting portion, and the second bent segment correspondingly forms the third abutting portion. The second abutting portion and the third abutting portion abut against the first terminal in a first direction on the side of the third abutting portion away from the second terminal.

[0009] Furthermore, the elastic portion is serpentine along the second direction, and the elastic portion includes a plurality of first bending segments, a plurality of second bending segments, and a plurality of connecting segments. The first bending segments and the second bending segments are arranged alternately along the second direction, and each first bending segment is connected to its adjacent second bending segment by only one connecting segment.

[0010] Furthermore, each of the first bending segments has a second abutment portion, each of the second bending segments has a third abutment portion, and each of the connecting segments has a first abutment portion.

[0011] Furthermore, the first mating portion is disposed on the first terminal, the second mating portion is disposed on the second terminal, the first terminal has a first limiting portion protruding in a first direction toward the side where the second terminal is located, the second terminal has a second limiting portion protruding in a first direction toward the side where the first terminal is located, the second limiting portion and the first limiting portion are spaced apart in a second direction, the third terminal is received between the first limiting portion and the second limiting portion, and the third terminal abuts against the first limiting portion and the second limiting portion in a second direction.

[0012] Furthermore, one of the first terminal and the second terminal includes a limiting groove, which penetrates one of the first terminal and the second terminal in a first direction. The first limiting portion or the second limiting portion corresponding to the other of the first terminal and the second terminal protrudes towards the limiting groove to form a protruding portion, which is received in the limiting groove, so that the protruding portion moves in the limiting groove in a second direction.

[0013] Furthermore, the first terminal includes a first flat plate portion and a first extension arm. The first extension arm is connected to the end of the first flat plate portion near the first docking element in a second direction. The first extension arm is bent and offset relative to the first flat plate portion toward the second terminal in a first direction. The first limiting portion protrudes from the first flat plate portion. The first docking portion is located at the end of the first extension arm near the first docking element. The second terminal includes a second flat plate portion and a second extension arm. The second extension arm is connected to the end of the second flat plate portion near the second docking element in a second direction. The second extension arm is bent and offset relative to the second flat plate portion toward the first terminal in a first direction. The second limiting portion protrudes from the second flat plate portion. The second docking portion is located at the end of the second extension arm near the second docking element.

[0014] Furthermore, both the first docking portion and the second docking portion are located at the third terminal.

[0015] Furthermore, the first terminal, the second terminal, and the third terminal are all formed by stamping metal sheets, and the elastic part is formed by bending the sheet surface to form an arch. The first terminal and the second terminal are arranged face to face in a first direction.

[0016] Another aspect of the present invention provides an electrical connector, comprising: a body having a plurality of receiving slots; and a plurality of conductive terminals as described above, the conductive terminals being received in the receiving slots.

[0017] Furthermore, the first terminal has a first flat plate portion, the second terminal has a second flat plate portion, and the elastic portion of the third terminal is at least partially arched toward the second terminal in a first direction. The first abutting portion is formed at the top of the arched elastic portion and abuts against the second flat plate portion. The second abutting portion and the third abutting portion are formed on both sides of the arched elastic portion and abut against the first flat plate portion. The conductive terminal is inserted into the corresponding receiving groove, and the inner wall of the receiving groove is recessed with a clearance groove. The clearance groove is located on the side of the second terminal away from the third terminal in the first direction. The clearance groove is correspondingly arranged with the first abutting portion in the first direction so that the second terminal is elastically deformed by the force applied by the first abutting portion, thus clearance of the second terminal.

[0018] Furthermore, the first terminal has a first flat plate portion, the second terminal has a second flat plate portion, and the elastic portion of the third terminal is at least partially arched toward the second terminal in a first direction. A first abutting portion is formed at the top of the arched elastic portion, abutting the second flat plate portion. The second and third abutting portions are formed on both sides of the arched elastic portion, abutting the first flat plate portion. The conductive terminal is inserted into the corresponding receiving groove. The inner wall of the receiving groove is recessed with two clearance grooves spaced apart in a third direction and a positioning partition wall located between the two clearance grooves. The clearance grooves are located on the side of the first terminal away from the third terminal in the first direction. The positioning partition wall abuts the first terminal in the first direction. One of the clearance grooves is correspondingly arranged with the second abutting portion in the first direction, and the other clearance groove is correspondingly arranged with the third abutting portion in the first direction, so that the first terminal is elastically deformed by the force applied by the second and third abutting portions, thus making room for the first terminal.

[0019] Furthermore, the maximum width of the conductive terminal in the third direction is greater than the maximum width in the first direction. Two conductive terminals that are adjacent and opposite to each other in the first direction form a differential signal pair, and the two conductive terminals are mirror images of each other in the first direction.

[0020] Furthermore, each of the receiving slots is provided with a first stop and a second stop, the first stop and the second stop being formed on both sides of the receiving slot in a first direction. One of the first terminal and the second terminal is provided with a first mating part, the first mating part cooperating with the first stop to limit the upper and lower movement. The other of the first terminal and the second terminal is provided with a second mating part, the second mating part cooperating with the second stop to limit the upper movement in a second direction, so that the first terminal and the second terminal can move between the first stop and the second stop in a second direction.

[0021] Furthermore, the second terminal, the third terminal, and the first terminal are sequentially inserted into the corresponding receiving slots. The first terminal has a guide portion on each side of its insertion end in the second direction and in the third direction. The guide portion is used to cooperate with the third terminal to guide the assembly of the first terminal.

[0022] Furthermore, the base includes a base with multiple receiving slots extending through the base in a second direction. The base also includes an insulating member corresponding to each receiving slot. The insulating member has two receiving slots spaced apart in a first direction, and each receiving slot corresponds to a conductive terminal. The base includes a metal seat formed by stacking multiple metal layers in a second direction and two grounding members. The two grounding members are fixedly connected to both sides of the metal seat in the second direction. One grounding member in the second direction is used to connect with the first docking element to form a common ground connection, and the other grounding member is used to connect with the second docking element to form a common ground connection. The grounding member includes a body and multiple spring arms. The body is connected to the metal seat, and the spring arms are integrally connected to the body. The multiple receiving slots are arranged in at least one row. Each row of receiving slots is arranged along a third direction. Two spring arms are provided between two adjacent receiving slots in the third direction. Both spring arms extend longitudinally in a first direction. The two spring arms are staggered in the first direction and in the third direction.

[0023] Compared with the prior art, the conductive terminals and electrical connectors of the present invention have the following advantages: In the conductive terminal of the present invention, a third terminal is provided between the first terminal and the second terminal. The second and third abutment portions on both sides of the third terminal in the third direction abut against the first terminal, thereby forming a transmission path from the second abutment portion to the third abutment portion between the third terminal and the second terminal. This path is shorter than that of the solution that requires passing through the entire elastic part, which can shorten the capacitive coupling length between the third terminal and the first terminal. The third terminal also has a first abutment portion that abuts against the second terminal, ensuring that the third terminal has stable abutment contact with the first terminal and the second terminal respectively. At least one connecting segment and the corresponding first and second bending segments are provided with a first abutment portion, a second abutment portion and a third abutment portion, thereby forming a transmission path from the first abutment portion to the second abutment portion and from the first abutment portion to the third abutment portion between the first terminal and the second terminal. This is shorter than the transmission path from the second abutment portion to the third abutment portion, further shortening the capacitive coupling length between the third terminal and the first and second terminals, improving the resonance of the conductive terminal in crosstalk and insertion loss, and thus improving the high-frequency performance of the electrical connector.

[0028] Furthermore, the terms "first" and "second" 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" or "second" 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.

[0029] In the first embodiment of the present invention, the first direction is the front-back direction, the second direction is the up-down direction, and the third direction is the left-right direction. In other embodiments, the first direction may also be the up-down direction or the left-right direction, the second direction may also be the front-back direction or the left-right direction, and the third direction may also be the front-back direction or the left-right direction. Of course, the second direction is perpendicular to the first direction, and the third direction is perpendicular to the first and second directions. In the following second, third, fourth, and fifth embodiments, the first direction, the second direction, and the third direction are all described according to the directions of the first embodiment. For ease of understanding, the Z-axis extension direction of the electrical connector 100 is defined as the up-down direction, where the positive Z-axis direction is upward; the Y-axis extension direction is defined as the left-right direction, where the positive Y-axis direction is to the right; and the X-axis extension direction is defined as the front-back direction, where the positive X-axis direction is forward.

[0030] like Figure 1 and Figure 8 As shown, the electrical connector 100 of the first embodiment of the present invention includes: a plurality of conductive terminals 1 and a base 2, wherein the plurality of conductive terminals 1 are disposed on the base 2. The conductive terminals 1 are used to connect between a first mating element 200 and a second mating element 300 in the vertical direction. The conductive terminals 1 are provided with a first mating portion 1a and a second mating portion 1b. The first mating portion 1a is used to mate with the first mating element 200, and the second mating portion 1b is used to mate with the second mating element 300. The first mating element 200 may be a circuit board, a chip, or a mating connector, and the second mating element 300 may be a circuit board, a chip, or a mating connector. In this embodiment, the first mating element 200 is located above the second mating element 300 and is a chip, while the second mating element 300 is a circuit board.

[0031] like Figure 2 and Figure 6 As shown, the conductive terminal 1 includes a first terminal 11, a second terminal 12, and a third terminal 13. The first terminal 11 and the second terminal 12 are arranged opposite each other in the front and back direction. The third terminal 13 is located between the first terminal 11 and the second terminal 12 in the front and back direction, and the third terminal 13 abuts against the first terminal 11 and the second terminal 12 respectively, so as to form a shorter transmission path between the first terminal 11 and the second terminal 12. The third terminal 13 is elastic and cooperates with the first terminal 11 and the second terminal 12, so that the conductive terminal 1 is similar to a POGOPIN structure.

[0032] like Figure 2 , Figure 4 and Figure 6 As shown, the first terminal 11 is plate-shaped and formed by stamping metal sheet, which facilitates manufacturing. The first terminal 11 includes a first flat plate portion 111, a first extending arm 112, a first limiting portion 113, a limiting groove 114, and a first mating portion 115. The first flat plate portion 111 has a longitudinally elongated plate structure in the vertical direction. The two plates of the first flat plate portion 111 are arranged facing each other. The first extending arm 112 is integrally connected to one end of the first flat plate portion 111 in the vertical direction. A guide portion 1111 is provided on each of the left and right sides of the end of the first flat plate portion 111 away from the first extending arm 112 in the vertical direction. The two guide portions 1111 are arranged from the side closer to the first extending arm 112 toward the side away from the first extending arm 112 toward each other. In other words, the arrangement of the two guide portions 1111 makes the end of the first flat plate portion 111 away from the first extending arm 112 approximately trapezoidal in the front-back direction. The first extension arm 112 is connected vertically to one end of the first flat plate 111 near the first docking element 200. The first extension arm 112 is bent and offset relative to the first flat plate 111 towards the second terminal 12 in the front-back direction. A first docking portion 1a is provided at the end of the first extension arm 112 near the first docking element 200, such that the first docking portion 1a is positioned in the middle relative to the entire conductive terminal 1 in the front-back direction, facilitating docking with the first docking element 200. A first limiting portion 113 protrudes from the first flat plate 111 on the side facing the second terminal 12 in the front-back direction, and is used to limit the vertical movement of the third terminal 13. A limiting groove 114 is provided on the first flat plate 111, and the limiting groove 114 is vertically spaced from the first limiting portion 113. The limiting groove 114 extends through the first flat plate 111 from front to back, and is used to cooperate with the second terminal 12, limiting the vertical movement range of the second terminal 12. The first mating part 115 protrudes from the first flat plate part 111 on the side away from the second terminal 12 in the front-back direction, and the first mating part 115 protrudes from the second flat plate part 121.

[0033] like Figure 2 and Figure 6As shown, the second terminal 12 is plate-shaped and formed by stamping metal sheet, which is convenient to manufacture. The second terminal 12 and the first terminal 11 are arranged plate-to-plate in the front-back direction. The second terminal 12 includes a second flat plate portion 121, a second extension arm 122, a second limiting portion 123, a protrusion portion 124, and a second mating portion 125. The second flat plate portion 121 has a longitudinally elongated plate-like structure in the vertical direction. The two plates of the second flat plate portion 121 are arranged facing each other. The second extension arm 122 is integrally connected to one end of the second flat plate portion 121 in the vertical direction. The second extension arm 122 is connected to one end of the second flat plate portion 121 near the second docking element 300 in the vertical direction. The second extension arm 122 is bent and offset relative to the second flat plate portion 121 toward the first terminal 11 in the front-back direction. The second docking portion 1b is provided at one end of the second extension arm 122 near the second docking element 300, so that the second docking portion 1b is located in the middle position relative to the entire conductive terminal 1 in the front-back direction, which facilitates docking with the second docking element 300. In addition, the second docking portion 1b and the first docking portion 1a are arranged vertically opposite each other in the vertical direction, so that the conductive terminal 1 is subjected to more uniform force and avoids the conductive terminal 1 from being skewed.

[0034] like Figure 2 and Figure 6 As shown, the second limiting part 123 is disposed on the side of the second flat plate part 121 facing the first terminal 11 in the front-back direction. The second limiting part 123 protrudes from the second flat plate part 121. The second limiting part 123 and the first limiting part 113 are arranged vertically at intervals. The third terminal 13 is received between the first limiting part 113 and the second limiting part 123 in the vertical direction, so that the third terminal 13 is compressed between the first limiting part 113 and the second limiting part 123. The upper and lower ends of the third terminal 13 abut against the first limiting part 113 and the second limiting part 123, thereby the first terminal 11 and the second terminal 12 move up and down in conjunction with the third terminal 13, so that the conductive terminal 1 as a whole has elasticity in the vertical direction.

[0035] like Figure 4 and Figure 5 As shown, the second limiting portion 123 in the second terminal 12 protrudes towards the limiting groove 114 to form a protruding portion 124. The protruding portion 124 is received in the limiting groove 114, allowing the protruding portion 124 to move up and down within the limiting groove 114. This prevents the second limiting portion 123 from scratching the first terminal 11 and also prevents excessive rebound of the terminal, ensuring that the terminal can move up and down within a certain range. Of course, in other embodiments, the second terminal 12 may also have a limiting groove 114 at a position corresponding to the first limiting portion 113 in the front-back direction, and the first limiting portion 113 protrudes towards the limiting groove 114 to form a protruding portion 124. The protruding portion 124 is received in the limiting groove 114, allowing the protruding portion 124 to move up and down within the limiting groove 114, thereby allowing the conductive terminal 1 to move up and down within a controllable range.

[0036] like Figure 2 , Figure 3 As shown, the second mating part 125 is formed on one end of the second flat plate part 121 in the vertical direction near the second extension arm 122. The width of the second flat plate part 121 in the horizontal direction is wider than the width of the second extension arm 122 in the horizontal direction, so that the left and right sides of the second flat plate part 121 protrude relative to the second extension arm 122 to form two second mating parts 125.

[0037] like Figure 2 , Figure 3 and Figure 6 As shown, the third terminal 13 is formed by stamping a metal sheet. The third terminal 13 includes an elastic portion 131, which has a serpentine bending structure in the vertical direction, giving it elasticity to expand and contract in the vertical direction. The elastic portion 131 is also bent towards the surface of the second terminal 12 in the front-back direction to form an arch. The elastic portion 131 includes a first bending section, a second bending section, and a connecting section 1313. At least one of the first bending section and the second bending section is provided in multiples. The first bending section 1311 and the second bending section 1312 are located on the left and right sides of the elastic portion 131, and the connecting section 1313 connects the adjacent first bending section 1311 and the second bending section 1312. In this embodiment, the elastic part 131 includes a plurality of first bending segments 1311, a plurality of second bending segments 1312 and a plurality of connecting segments 1313. The first bending segments 1311 and the second bending segments 1312 are arranged alternately in the vertical direction. Each first bending segment 1311 is connected to its adjacent second bending segment 1312 by only one connecting segment 1313, which has better elasticity.

[0038] like Figure 6 and Figure 7As shown, the top of the elastic portion 131, which arches in the front-rear direction, forms at least one first abutment portion 131a for abutting against the second flat plate portion 121 of the second terminal 12 in the front-rear direction. The elastic portion 131 also includes a plurality of second abutment portions 131b formed on the left side of the first abutment portion 131a, and a plurality of third abutment portions 131c formed on the right side of the first abutment portion 131a. In this embodiment, each connecting segment 1313 is provided with a first abutment portion 131a, and a corresponding first abutment portion 131a is formed at the middle position of the connecting segment 1313 in the left-right direction. The first bending segment 1311 and the second bending segment 1312 are located on both sides of the arch of the elastic portion 131, and each first bending segment 1311 is provided with a second abutment portion 131. b. Each second bend segment 1312 is provided with a third abutment portion 131c. The second abutment portion 131b and the third abutment portion 131c abut against the first plate portion 111 of the first terminal 11 in the front-back direction on the side of the first abutment portion 131a away from the second terminal 12. This forms a transmission path between the first terminal 11 and the second terminal 12 from the first abutment portion 131a to the second abutment portion 131b and from the first abutment portion 131a to the third abutment portion 131c. This transmission path is shorter than the transmission path from the second abutment portion 131b to the third abutment portion 131c. This shortens the capacitive coupling length between the third terminal 13 and the first terminal 11 and the second terminal 12, improves the resonance of the conductive terminal 1 in crosstalk and insertion loss, and thus improves the high-frequency performance of the electrical connector 100.

[0039] like Figure 1 , Figure 8 and Figure 10As shown, the base 2 includes a base 21 and multiple insulating components 23. The base 21 has multiple receiving grooves 22, which extend vertically through the base 21. The multiple receiving grooves 22 are arranged in at least one row in the front-back direction, and each row of receiving grooves 22 is arranged in the left-right direction. Each receiving groove 22 has a corresponding insulating component 23. In this embodiment, the multiple receiving grooves 22 are arranged in multiple rows in the front-back direction, and adjacent rows of receiving grooves 22 are staggered left and right. The base 21 includes a metal seat 211 formed by stacking multiple metal sheets 2111 and two grounding components 212. The two grounding components 212 are fixedly connected to the upper and lower sides of the metal seat 211. One grounding component 212 in the top-bottom direction is used to connect with the first docking element 200 to form a common ground connection, and the other grounding component 212 is used to connect with the second docking element 300 to form a common ground connection. The grounding component 212 includes a main body 2121 and multiple spring arms 2122. The main body 2121 is fixedly connected to the metal base 211, and the spring arms 2122 are integrally connected to the main body 2121. The spring arms 2122 can be cantilever beams or simply supported beams. Two spring arms 2122 are provided between two adjacent receiving slots 22 in the left-right direction. Both spring arms 2122 extend longitudinally in the front-back direction. The two spring arms 2122 are staggered front-back to better shield the two conductive terminals 1 in the receiving slots 22. The staggered left-right arrangement of the two spring arms 2122 also facilitates connection to the main body 2121.

[0040] like Figure 8 and Figure 13 As shown, each insulating member 23 has two receiving grooves 24 spaced apart front to back. Each receiving groove 24 extends vertically through the corresponding insulating member 23 and receives one conductive terminal 1. Multiple insulating members 23 have multiple receiving grooves 24, and each receiving groove 24 receives multiple conductive terminals 1. In this embodiment, the inner wall of the receiving groove 24 is recessed with three clearance grooves 241. One clearance groove 241 is provided on the side of the second terminal 12 away from the third terminal 13 in the front-back direction. This clearance groove 241 is arranged front-back with the first abutment portion 131a so that the second terminal 12 is elastically deformed by the force applied by the first abutment portion 131a, thus making room for the second terminal 12. Two clearance grooves 241 are provided on the side of the first terminal 11 away from the third terminal 13 in the front-back direction, and the other two clearance grooves 241 are spaced apart left and right. The two relief grooves 241 are positioned such that a positioning partition 242 is formed between them. The positioning partition 242 abuts against the first terminal 11 in the front-back direction. One of the two relief grooves 241 is arranged in a front-back correspondence with the second abutment part 131b, and the other is arranged in a front-back correspondence with the third abutment part 131c. This allows the first terminal 11 to be elastically deformed by the force applied by the second abutment part 131b and the third abutment part 131c, thus making room for the first terminal 11 and ensuring that the third terminal 13 is in close contact with both the first terminal 11 and the second terminal 12.

[0041] like Figure 1 and Figure 8 As shown, two conductive terminals 1 housed in the same insulating member 23 and spaced apart front to back form a differential signal pair. Within the limited space occupied by a pair of differential signal pairs, the maximum width of each conductive terminal 1 in the differential signal pair in the left-right direction is greater than the maximum width in the front-back direction. The two conductive terminals 1 in the differential signal pair are arranged face-to-face, which increases the distance between the two conductive terminals 1, thereby adjusting the impedance of the conductive terminals 1. The two conductive terminals 1 are mirror images in the front-back direction, ensuring the simultaneity of signal transmission in the two conductive terminals 1 of the differential signal pair, thus improving the high-frequency performance of the electrical connector 100. In this embodiment, the conductive terminals 1 are inserted into corresponding receiving slots 24. Specifically, the second terminal 12, the third terminal 13, and the first terminal 11 are sequentially inserted into the corresponding receiving slots 24. When assembling the first terminal 11 last, the guide portions 1111 on the left and right sides of the insertion end of the first terminal 11 in the up-down direction can cooperate with the third terminal 13 to guide the assembly of the first terminal 11.

[0042] like Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, each receiving groove 24 is further provided with a first stop 243 and a second stop 244. The first stop 243 and the second stop 244 are formed on the front and rear sides of the receiving groove 24. The first mating portion 115 of the first terminal 11 is barbed and engages with the first stop 243 to limit its vertical movement. The second mating portion 125 of the second terminal 12 engages with the second stop 244 to limit its vertical movement, so that the first terminal 11 and the second terminal 12 can move up and down between the first stop 243 and the second stop 244, thereby preventing the first terminal 11 and the second terminal 12 from falling out of the receiving groove 24. In other embodiments, the first mating portion 115 may be provided on the second terminal 12 to engage with the first stop 243, and the second mating portion 125 may be provided on the first terminal 11 to engage with the second stop 244.

[0043] like Figure 14 As shown, in other embodiments, the inner wall of the receiving groove 24 is recessed with a relief groove 241. The relief groove 241 is located on the side of the second terminal 12 away from the third terminal 13 in the front-back direction. The relief groove 241 is arranged in a front-back correspondence with the first abutment portion 131a, so that the second terminal 12 is elastically deformed by the force applied by the first abutment portion 131a, making room for the second terminal 12, which facilitates the assembly of the third terminal 13. Furthermore, the second terminal 12 is elastically deformed under the force when the third terminal 13 is bent, which enables the third terminal 13 to be in close contact with both the first terminal 11 and the second terminal 12.

[0044] like Figure 15As shown, in other embodiments, the conductive terminal 1 is inserted into the corresponding receiving groove 24. The inner wall of the receiving groove 24 is recessed with two clearance grooves 241 spaced apart from left to right and a positioning partition 242 formed between the two clearance grooves 241. The clearance grooves 241 are located on the side of the first terminal 11 away from the third terminal 13 in the front-back direction. The positioning partition 242 abuts against the first terminal 11 in the front-back direction. One clearance groove 241 is arranged in front-back correspondence with the second abutment portion 131b, and the other clearance groove 241 is arranged in front-back correspondence with the third abutment portion 131c, so that the first terminal 11 is elastically deformed by the force applied by the second abutment portion 131b and the third abutment portion 131c, making room for the first terminal 11, so that the third terminal 13 is in close contact with both the first terminal 11 and the second terminal 12.

[0045] like Figure 16 As shown, in the second embodiment of the conductive terminal 1, the first terminal 11 and the second terminal 12 of the conductive terminal 1 have the same structure and connection relationship as in the first embodiment. The elastic part 131 in the third terminal 13 has a first abutment part 131a only in part of the first bending section 1311 and a second abutment part 131b only in part of the second bending section 1312, which reduces the contact points between the third terminal 13 and the first terminal 11. This reduces the friction between the third terminal 13 and the first terminal 11 when the third terminal 13 moves up and down, thereby adjusting the positive force of the entire conductive terminal 1. In this embodiment, at least one connecting segment 1313 and its connected first bending segment 1311 and second bending segment 1312 are provided with a first abutting portion 131a, a second abutting portion 131b and a third abutting portion 131c to shorten the signal transmission path and thereby improve the high-frequency performance of the electrical connector 100. The elastic part 131 is provided with at least one of the first abutting portion 131a, the second abutting portion 131b and the third abutting portion 131c at both ends in the vertical direction, and at least one of the first abutting portion 131a, the second abutting portion 131b and the third abutting portion 131c is provided in the middle part between the two ends in the vertical direction. Specifically, one of the connecting segments 1313 at the two ends in the vertical direction and the middle part between the two ends of the elastic part 131, as well as the first bending segment 1311 and the second bending segment 1312 connected thereto, are provided with the first abutting portion 131a, the second abutting portion 131b and the third abutting portion 131c respectively.

[0046] like Figure 7 As shown, in the third embodiment of the conductive terminal 1, the first mating portion 1a of the conductive terminal 1 is provided on one side of the third terminal 13 in the vertical direction, and the second mating portion 1b is provided on the side of the first terminal 11 or the second terminal 12 away from the first mating portion 1a in the vertical direction.

[0047] like Figure 18As shown, in the fourth embodiment of the conductive terminal 1, the first mating portion 1a and the second mating portion 1b of the conductive terminal 1 are disposed at the upper and lower ends of the third terminal 13. The length of the third terminal 13 in the vertical direction is greater than the length of the first terminal 11 in the vertical direction, and the length of the third terminal 13 in the vertical direction is greater than the length of the second terminal 12 in the vertical direction. When the conductive terminal 1 is mated with the first mating element 200 and the second mating element 300, the elastic mating is formed only by the vertical movement of the third terminal 13. The first terminal 11 and the second terminal 12 are fixed in the receiving groove 24 and do not move up and down.

[0048] like Figure 19 As shown, in the fifth embodiment of the conductive terminal 1, the third terminal 13 of the conductive terminal 1 is plate-shaped in the front-back direction and has no arched portion. The first terminal 11 is arched towards the third terminal 13 in the front-back direction, such that the top of the arched portion of the first terminal 11 abuts against the first abutting portion 131a of the third terminal 13. The second terminal 12 is arched away from the third terminal 13 in the front-back direction, such that the two sides of the arched portion of the second terminal 12 abut against the second abutting portion 131b and the third abutting portion 131c of the third terminal 13. Of course, in other embodiments, the first terminal 11 may also have a convex structure protruding towards the third terminal 13 in the front-back direction and abutting against the first abutting portion 131a of the third terminal 13. The second terminal 12 may also have convex structures protruding towards the third terminal 13 in the front-back direction on both the left and right sides, abutting against the second abutting portion 131b and the third abutting portion 131c of the third terminal 13.

[0049] exist Figure 2 , Figure 16 , Figure 17 and Figure 18 As shown, there are various configuration options for the first mating portion 1a and the second mating portion 1b of the conductive terminal 1, and various conductive terminal 1 structures can be combined. Figure 13 , Figure 14 and Figure 15 The structure of any of the receiving slots 24 shown is as follows: Figure 19 The conductive terminal 1 shown can also be configured in any of the following ways: first mating part 1a and second mating part 1b.

[0050] In other embodiments (not shown in the figures), the third terminal 13 in the first, second, third, fourth, and fifth embodiments described above can be replaced by an elastic part 131 having an "8" shaped structure or multiple consecutive "8" shaped structures in the vertical direction. The elastic part 131 includes multiple first bending segments 1311, multiple second bending segments 1312, and multiple connecting segments 1313. The multiple first bending segments 1311 and multiple second bending segments 1312 are arranged symmetrically from left to right. In the horizontal direction, each first bending segment 1311 and its opposite second bending segment 1312 are integrally connected by two connecting segments 1313. The two connecting segments 1313 are arranged vertically spaced apart. In the vertical direction, the two adjacent connecting segments 1313 that are integrally connected by two adjacent first bending segments 1311 are integrally connected at the middle part in the horizontal direction, which can increase the strength of the terminal and prevent the terminal from deforming.

[0051] In summary, the conductive terminals and electrical connectors of the present invention have the following beneficial effects: (1) In the conductive terminal 1 of the present invention, a third terminal 13 is provided between the first terminal 11 and the second terminal 12. The second abutment portion 131b and the third abutment portion 131c on both sides of the third terminal 13 in the third direction abut against the first terminal, so that a transmission path from the second abutment portion to the third abutment portion is formed between the third terminal and the second terminal. The path is shorter than that of the solution that needs to pass through the entire elastic part 131, which can shorten the capacitive coupling length between the third terminal 13 and the first terminal 11. The third terminal 13 also has a first abutment portion 131a abutting against the second terminal 12, ensuring that the third terminal 13 is stably abutted against the first terminal 11 and the second terminal 12 respectively, and at least one connection The segment 1313 and its corresponding first bent segment 1311 and second bent segment 1312 are provided with a first abutment portion 131a, a second abutment portion 131b and a third abutment portion 131c, thereby forming a transmission path from the first abutment portion 131a to the second abutment portion 131b and from the first abutment portion 131a to the third abutment portion 131c between the first terminal 11 and the second terminal 12. This transmission path is shorter than the transmission path from the second abutment portion 131b to the third abutment portion 131c, further shortening the capacitive coupling length between the third terminal 13 and the first terminal 11 and the second terminal 12, improving the resonance of the conductive terminal 1 in crosstalk and insertion loss, and thus improving the high-frequency performance of the electrical connector 100.

[0052] (2) The elastic part 131 is provided with at least one of the first abutting part 131a, the second abutting part 131b and the third abutting part 131c at both ends and the middle part in the second direction, so that the capacitive coupling length of the third terminal 13 in the second direction is shortened, and the resonance of the conductive terminal 1 in crosstalk and insertion loss is further improved.

[0053] (3) By arching the elastic part 131 of the third terminal 13 in the first direction, the third terminal 13 can be tightly contacted with the first and second terminals 12, making manufacturing simpler and the connection of the conductive terminal 1 more stable.

[0054] (4) The elastic part 131 is serpentine, and the first bending segment 1311 and the second bending segment 1312 are arranged alternately along the second direction. Each first bending segment 1311 and its adjacent second bending segment 1312 are connected by only one connecting segment 1313, so that the elastic part 131 has better elasticity.

[0055] (5) Each first bending segment 1311 has a first abutting part 131a, each second bending segment 1312 has a second abutting part 131b, and each connecting segment 1313 has a third abutting part 131c. This increases the abutting contact points between the third terminal 13 and the first terminal 11 and the second terminal 12, thereby increasing the number of signal transmission paths formed between the first terminal 11 and the second terminal 12, further shortening the capacitive coupling length between the third terminal 13 and the first terminal 11 and the second terminal 12, thereby further improving the resonance of the conductive terminal 1 in crosstalk and insertion loss, and thus improving the high-frequency performance of the electrical connector 100.

[0056] (6) The first mating part 1a is provided on the first terminal 11 and the second mating part 1b is provided on the second terminal 12. Compared with the scheme where the first mating part 1a or the second mating part 1b is provided on the third terminal 13, the first terminal 11 and the second terminal 12 are not elastic and will not bend or deflect when mating with the first mating element 200 and the second mating element 300, so that the conductive terminal 1 is more stable in mating with the first mating element 200 and the second mating element 300. The third terminal 13 is housed between the first limiting part 113 of the first terminal 11 and the second limiting part 123 of the second terminal 12, which can ensure that the third terminal 13 moves in the second direction within a limited range, preventing the third terminal 13 from falling out of the electrical connector 100. The third terminal 13 abuts against the first limiting part 113 and the second limiting part 123 in the second direction, so that the first terminal 11 and the second terminal 12 can move in the second direction through the third terminal 13, so that the entire conductive terminal 1 has elasticity that can contract in the second direction.

[0057] (7) The first terminal 11 includes a limiting groove 114. The second limiting part 123 corresponding to the second terminal 12 protrudes towards the limiting groove 114 to form a protruding part 124. The protruding part 124 is received in the limiting groove 114, so that the protruding part 124 can move in the limiting groove 114. This can prevent the second limiting part 123 from scratching the first terminal 11 and also prevent the third terminal 13 from being over-compressed, ensuring that the first terminal 11 and the second terminal 12 can move in the second direction within a certain range.

[0058] (8) The first extension arm 112 is offset relative to the first plate portion 111 toward the second terminal 12 in the first direction. The first extension arm 112 is provided with a first docking portion 1a at one end near the first docking element 200, so that the first docking portion 1a is located in the middle position relative to the entire conductive terminal 1 in the first direction, which facilitates docking with the first docking element 200. The second extension arm 122 is offset relative to the second plate portion 121 toward the first terminal 11 in the first direction. The second docking portion 1b is provided at one end of the second extension arm 122 near the second docking element 300, so that the second docking portion 1b is located in the middle position relative to the entire conductive terminal 1 in the first direction, which facilitates docking with the second docking element 300.

[0059] (9) The first docking part 1a and the second docking part 1b are both provided on the third terminal 13, so that the third terminal 13 can be uniformly subjected to force in the second direction, and avoid the conductive terminal 1 from being skewed.

[0060] (10) The first terminal 11, the second terminal 12 and the third terminal 13 are all formed by stamping metal sheet. The elastic part 131 is formed by bending the plate surface to form an arch. The first terminal 11 and the second terminal 12 are arranged plate to plate in the first direction, which facilitates the manufacturing of conductive terminal 1 and is conducive to mass production of conductive terminal 1.

[0061] (11) A clearance groove 241 is provided on the side of the second terminal 12 away from the third terminal 13 in the receiving groove 24. The second terminal 12 is elastically deformed under force when the third terminal 13 is bent, thereby making room for the second terminal 12, which facilitates the assembly of the third terminal 13 and the first terminal 11. The second terminal 12 is elastically deformed under force when the third terminal 13 is bent, which enables the second terminal 12 to be in close contact with the first terminal 11 and the third terminal 13.

[0062] (12) On the side of the first terminal 11 away from the third terminal 13 in the receiving groove 24, two clearance grooves 241 and a positioning partition wall 242 are provided at intervals in the third direction. When the third terminal 13 abuts against the first terminal 11, the first terminal 11 is elastically deformed by the force applied by the second abutment part 131b and the third abutment part 131c, making room for the first terminal 11, which facilitates the installation of the third terminal 13 and the second terminal 12. Furthermore, the first terminal 11 is elastically deformed under the force when the third terminal 13 is bent, which enables the second terminal 12 to be in close contact with both the first terminal 11 and the third terminal 13.

[0063] (13) Two conductive terminals 1 housed in the same insulating member 23 and spaced apart front and back form a differential signal pair. Within the limited space occupied by a pair of differential signal pairs, the maximum width of each conductive terminal 1 in the differential signal pair in the left-right direction is greater than the maximum width in the front-back direction. The two conductive terminals 1 in the differential signal pair are arranged face to face, which increases the distance between the two conductive terminals 1 and adjusts the impedance of the conductive terminals 1. The two conductive terminals 1 are arranged in a mirror image, which ensures the precise time alignment of the differential signal in the two conductive terminals 1 in the differential signal pair and improves the high-frequency performance of the electrical connector 100.

[0064] (14) A first stop 243 and a second stop 244 are provided in the receiving groove 24. A first mating part 115 and a second mating part 125 are provided in the first terminal 11 and the second terminal 12. The first mating part 115 and the first stop 243 are mated in the upper limit position in the second direction. The second mating part 125 and the second stop 244 are mated in the upper limit position in the second direction, thereby preventing the first terminal 11 and the second terminal 12 from falling out of the receiving groove 24, so that the first terminal 11 and the second terminal 12 can move between the first stop 243 and the second stop 244.

[0065] (15) Two spring arms 2122 are provided between two adjacent receiving slots 22 in the third direction. Both spring arms 2122 extend longitudinally along the first direction. The two spring arms 2122 are staggered in the first direction, which can better shield the two conductive terminals 1 in the receiving slots 22. When the receiving slots 22 are provided with receiving slots 24 at intervals in the first direction to receive the conductive terminals 1, the gap between the two adjacent receiving slots 22 in the third direction is small. Therefore, the two spring arms 2122 are staggered in the third direction, which facilitates the connection of the main body 2121.

[0066] The above detailed description is only an illustration of a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
