Description

Technical Field

[0001] This invention relates to a conductive component and a connector having the conductive component, and more particularly to a high-precision conductive component. Background Technology

[0002] A conductive component is disclosed in the prior art, comprising a conductive element, a contact element, and an elastic element. The conductive element is formed by bending a metal sheet into a cylindrical structure. The cylindrical structure has a first end and a second end disposed opposite to each other in a first direction, and a through hole passing through the first end and the second end. The first end has a plurality of clamping arms distributed circumferentially. The ends of each clamping arm are bent to form an inwardly folded portion at the end of the clamping arm. The contact element is assembled in the through hole of the conductive element and is clamped by the folded portion of the clamping arm. The elastic element is received in the through hole and abuts against the contact element.

[0003] However, in the existing technology, bending the ends of each clamping arm to form an inwardly folded section at the end of the clamping arm makes it difficult to maintain a consistent curvature of the multiple folds. This results in the clamping force of the multiple clamping arms on the contact element being either too loose or too tight, leading to low precision of the conductive components.

[0004] Therefore, it is necessary to design a high-precision conductive component to overcome the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision conductive component and connector. By forming the conductive parts in the conductive component through a turning process, the clamping force of the clamping arms of the conductive parts on the contact parts in the conductive component is more stable, thereby improving the precision of the conductive component and connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A conductive component includes: a conductive member having a first end and a second end disposed opposite to each other in a first direction; the conductive member includes a through hole formed by a turning process, penetrating the first end and the second end; the through hole has an inwardly constricted opening at the first end, the opening being circular with a first diameter; the conductive member has a plurality of slots formed on the outer periphery of the through hole, the slots communicating with the through hole and penetrating the first end of the conductive member in the first direction but not penetrating the second end, thereby forming a plurality of independent clamping arms; the clamping arms have an abutment facing the opening at positions corresponding to the openings. A component; a contact element assembled on a conductive component, the contact element including a contact segment and a limiting segment and a mating portion located on opposite sides of the contact segment in a first direction, the mating portion being exposed outside the opening for mating with a mating component, the limiting segment protruding outward relative to the outer periphery of the contact segment and being received in a through hole, the contact segment being circular with a second diameter in a cross section perpendicular to the first direction, the second diameter being larger than the first diameter, the contact segment passing through the opening at one end near the mating portion in the first direction, the abutting portion being propped open by the contact segment; an elastic element received in the through hole, the elastic element abutting against the contact element.

[0007] Furthermore, there are two slots, which are arranged opposite each other along one of the diameter directions of the through hole. The two clamping arms formed therefrom are symmetrically arranged along the other diameter direction of the through hole, and the abutting part is an arc surface facing the opening.

[0008] Furthermore, the outer diameter of the portion of the conductive member corresponding to the clamping arm gradually decreases toward the first end in the first direction, the clamping arm has a root portion corresponding to the adjacent slot away from the opening end in the first direction, and the thickness of the clamping arm from the root portion to the abutment portion gradually decreases toward the first end in the first direction.

[0010] Furthermore, it also includes a conductive plug housed in the through hole, the conductive plug being positioned by interference with the inner wall of the through hole to divide the through hole into two spaced receiving holes along the first direction, wherein one receiving hole closer to the opening is used to house an elastic member and a contact member, the side of the elastic member away from the contact member along the first direction abuts against the conductive plug, and the other receiving hole away from the opening is used to house a signal line.

[0011] Furthermore, it also includes a signal line assembled from the second end into the through hole, the signal line abutting against the side of the elastic member away from the contact member in the first direction.

[0012] A connector includes: a base having a first side and a second side disposed opposite to each other in a first direction; a plurality of conductive components as described above, the plurality of conductive components being correspondingly housed in the base, and a mating portion being exposed on the first side for elastically mating with a mating member.

[0013] Furthermore, the base includes a conductive body, an elastic conductive base, and multiple insulating components. The conductive body is provided with multiple receiving grooves, and the insulating components are received in the receiving grooves. The insulating components are provided with at least one receiving groove, and the conductive components are received in the receiving grooves for transmitting signals. The first side is provided on the elastic conductive base, and the elastic conductive base surrounds the insulating components to tightly fit the mating components, thereby realizing an electrical connection between the conductive body and the mating components and forming a grounding path.

[0014] Furthermore, the base includes a conductive body and multiple insulating components. The conductive body is provided with multiple receiving slots, and the insulating components are received in the receiving slots. Each insulating component is provided with two receiving slots and a connecting slot. The two receiving slots are used to receive two conductive components that transmit differential signals. The connecting slot passes through the insulating component in a first direction and connects the two receiving slots.

[0015] Furthermore, the base also includes at least one elastic conductor, which has a mounting groove extending through it in a first direction. The connector assembly includes at least one cable mounted in the mounting groove. The cable includes two signal lines, an insulating layer covering each signal line, and a shielding layer covering the two signal lines. The shielding layer is electrically connected to the elastic conductor. The mounting groove extends beyond the shielding layer in the first direction towards the first side, forming a receiving space on one side of the shielding layer. The signal lines are exposed outside the insulating layer along the first direction towards the first side, and a portion of the signal lines are exposed in the receiving space. A portion of the signal lines protrudes out of the receiving space and inserts into a through hole to connect with a conductive element. The receiving space is filled with insulating adhesive to electrically isolate the signal lines from the elastic conductor.

[0016] Furthermore, at least one annular stop portion is provided protruding inward from the mounting groove. The annular stop portion abuts against the shielding layer. The receiving space is located on the side of the annular stop portion closer to the first side in the first direction. The annular stop portion is used to block the insulating adhesive in the first direction.

[0017] Furthermore, the elastic conductor is provided with an injection hole and an overflow hole, both of which are connected to the receiving space. Insulating adhesive is injected into the elastic conductor through the injection hole, and the overflow hole is used to allow the insulating adhesive to overflow.

[0018] Furthermore, the base also includes a conductive body, with the second side disposed on the conductive body. The conductive body has multiple assembly slots, with two adjacent assembly slots connected along a direction perpendicular to the first direction. The elastic conductors carrying cables are assembled in the assembly slots one by one. The shielding layer of the cable and the conductive body are electrically connected through the elastic conductors. The elastic conductors in two adjacent assembly slots are in contact with each other and connected.

[0019] Furthermore, the base includes a conductive body, multiple insulating components, and a limiting component. The conductive body has multiple receiving grooves, and the multiple insulating components are assembled one-to-one into the multiple receiving grooves along a first direction toward a first side. Each receiving groove has a limiting portion, and each insulating component has a mating portion. The mating portion and the limiting portion cooperate to stop the insulating component in the assembly direction of the insulating component. The limiting component is located on the side of the conductive body away from the first side in the first direction. The limiting component includes a base connected to the conductive body. The limiting component has multiple openings that penetrate the base in the first direction. The multiple openings are correspondingly arranged with the multiple receiving grooves in the first direction. At least one limiting portion is provided between adjacent openings. The limiting portion stops on one side of the receiving groove in the first direction to prevent the insulating component from exiting the receiving groove. The limiting portion is elastic in the direction perpendicular to the first direction so that when the insulating component is assembled into the corresponding receiving groove, the limiting portion can allow the insulating component to move out of the receiving groove through elastic deformation.

[0020] Furthermore, the base includes a conductive body and multiple insulating components. The conductive body is provided with multiple receiving grooves, and the insulating components are received in the receiving grooves. The insulating components are provided with at least one receiving groove, and the conductive components are received in the receiving grooves for transmitting signals. The receiving grooves include a first groove and a second groove. The first groove is closer to the first side relative to the second groove in a first direction. The first groove is connected to the second groove in the first direction. The second groove is arranged to be expanded outward relative to the first groove in a direction perpendicular to the first direction. The conductive components include, from the first end to the second end, a first segment, a second segment, and a third segment in sequence. The outer diameter of the first segment is larger than the outer diameter of the second segment, and the outer diameter of the first segment is smaller than the outer diameter of the third segment. The first segment and the second segment are respectively received in the first groove, and the third segment is respectively received in the second groove.

[0021] Compared with the prior art, the conductive components and connectors of the present invention have the following advantages: In this invention, the conductive component of the conductive assembly is formed by machining a through hole that extends through the first and second ends. An inwardly tapering opening is formed at the first end of the through hole, resulting in a more precise size of the opening. Compared to the prior art where the clamping arm of the conductive component is bent to form an abutment, the abutment formed at the position of the clamping arm facing the opening in this invention generates a more stable force when abutting the contact section. This avoids the clamping arm clamping the contact section too tightly or too loosely, improving the precision of the conductive assembly. Consequently, the clamping force on the contacts of multiple conductive components in the connector remains highly consistent, thereby improving the overall precision of the connector.

[0023] Explanation of reference numerals in the accompanying drawings for the specific implementation methods: Detailed Implementation

[0024] To make the objectives, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] In the description of this invention, unless otherwise expressly specified and limited, the terms "installation," "connection," "assembly," 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 components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. 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 indicated technical features. Thus, a feature defined with "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 expressly and specifically limited.

[0026] In this invention, the first direction is the vertical direction. The following specific embodiments are mainly described using the vertical, front-back, and left-right directions. In other embodiments, the first direction may also be the front-back or left-right direction.

[0027] For ease of understanding, the Z-axis extension direction of the connector is defined as the up-down direction, with the positive Z-axis direction being upward; the Y-axis extension direction is defined as the left-right direction, with the positive Y-axis direction being to the right; and the X-axis extension direction is defined as the front-back direction, with the positive X-axis direction being forward.

[0028] like Figure 1 and Figure 11 As shown, the connector 100 of the present invention includes a plurality of conductive components 10Q and a base 10R. The base 10R has a first side 1R1 and a second side 1R2 disposed opposite to each other in the vertical direction. The plurality of conductive components 10Q are mounted on the base 10R, and the conductive components 10Q are exposed on the first side 1R1 for elastically engaging with a mating member 200. Specifically, the mating member 200 may be a circuit board or a mating connector 100. In this embodiment, the mating member 200 is a circuit board.

[0029] like Figure 5 and Figure 7 As shown, the conductive component 10Q includes a conductive element 10, a contact element 11, and an elastic element 12. The elastic element 12 and the contact element 11 are assembled on the conductive element 10, and the elastic element 12 and the contact element 11 are in contact.

[0030] like Figure 6 and Figure 8As shown, the conductive element 10 has a first end 101 and a second end 102 disposed opposite to each other in the vertical direction. The conductive element 10 is formed from a metal columnar material by a turning process. The conductive element 10 includes a through hole 103 formed by a turning process, penetrating through the first end 101 and the second end 102. Specifically, the through hole 103 is a circular hole, and a large part of the inner diameter of the through hole 103 remains constant. The inner diameter of the constant part of the through hole 103 is a third diameter ϕ3. The through hole 103 forms an inwardly contracting opening 1031 at the first end 101. The opening 1031 is a circle with a first diameter ϕ1, which is smaller than the third diameter ϕ3. Specifically, a larger cutting tool can be used to drill a part of the through hole 103 from the second end 102 of the conductive element 10, and then a smaller cutting tool can be used to drill the opening 1031 near the first end 101, thereby forming an inwardly contracting opening 1031 at the first end 101.

[0031] like Figure 6 and Figure 8 As shown, the conductive element 10 has a plurality of slots 104 formed on the outer periphery of the through hole 103. The slots 104 extend longitudinally in the vertical direction and communicate with the through hole 103. The slots 104 penetrate the first end 101 of the conductive element 10 in the vertical direction but do not penetrate the second end 102, thereby forming a clamping arm 105 between every two adjacent slots 104. Consequently, a plurality of independent clamping arms 105 are formed on the side of the conductive element 10 that is closer to the first end 101 than the second end 102. 05. The clamping arm 105 has an abutment portion 1051 facing the opening 1031 at the position corresponding to the opening 1031. It can be understood that the opening 1031 is inwardly contracted relative to the through hole 103. Therefore, when the clamping arm 105 is formed, the position of the clamping arm 105 corresponding to the opening 1031 will form an abutment portion 1051 that protrudes inwardly relative to the other parts of the clamping arm 105 except for the position of the opening 1031. That is to say, the abutment portion 1051 is the inner wall of the opening 1031. In this embodiment, there are two slots 104. The two slots 104 are arranged opposite each other along one of the diameter directions of the through hole 103. The two clamping arms 105 formed accordingly are symmetrically arranged along the other diameter direction of the through hole 103. The abutment portion 1051 is an arc surface facing the opening 1031. In other embodiments, more slots 104 may be provided, for example, three, four or five slots 104 may be provided, corresponding to three, four or five clamping arms 105, etc., and these slots 104 may be evenly distributed along the circumference of the conductive element 10.

[0032] like Figure 6 and Figure 7As shown, the outer diameter of the portion of the conductive member 10 corresponding to the clamping arm 105 gradually decreases in the vertical direction toward the first end 101. The clamping arm 105 has a root portion 1052 corresponding to the adjacent slot 104 at the end away from the opening 1031 in the vertical direction. The thickness of the clamping arm 105 from the root portion 1052 to the abutment portion 1051 gradually decreases in the vertical direction toward the first end 101, thereby making the clamping arm 105 more elastic near the opening 1031. The conductive component 10 includes a first segment P1, a second segment P2, and a third segment P3 sequentially from the first end 101 to the second end 102. The outer diameter of the first segment P1 is larger than that of the second segment P2, and the outer diameter of the first segment P1 is smaller than that of the third segment P3, so as to adjust the overall impedance of the conductive component 10Q and make the impedance of the conductive component 10Q more matched. Since the conductive component 10 is provided with a through hole 103, a thickness is formed between the outer wall surface and the inner wall surface of the conductive component 10, and the inner diameter of the through hole 103 remains mostly constant. Therefore, the thickness of the first segment P1 is greater than that of the second segment P2, and the thickness of the first segment P1 is smaller than that of the third segment P3.

[0033] like Figure 5 , Figure 7 and Figure 8As shown, the contact member 11 includes a contact segment 111, a limiting segment 112 located on opposite sides of the contact segment 111 in the vertical direction, and a mating portion 113. The mating portion 113 is exposed outside the opening 1031 and is used to mate with the mating member 200. The limiting segment 112 protrudes outward relative to the outer periphery of the contact segment 111 and is received in the through hole 103. The limiting segment 112 is blocked by the opening 1031 in the vertical direction, thereby preventing the contact member 11 from exiting the through hole 103. The contact segment 111 is circular with a second diameter ϕ2 in a cross section perpendicular to the vertical direction. The second diameter ϕ2 is larger than the first diameter ϕ1 and smaller than the third diameter ϕ3. Because the end of the contact segment 111 close to the mating portion 113 passes through the opening 1031 in the vertical direction, the abutting portion 1051 is opened by the contact segment 111, so that the abutting portion 1051 stably abuts against the contact segment 111. The through hole 103 and the opening 1031 of the conductive component 10 are both formed by turning process, so the size of the opening 1031 is manufactured with greater precision. Compared with the prior art where the clamping arm 105 of the conductive component 10 is bent to form the abutment part 1051, the abutment part 1051 formed by our company at the position of the clamping arm 105 facing the opening 1031 generates a more stable force when it abuts the clamping contact section 111, which can avoid the clamping arm 105 clamping the contact section 111 too tightly or too loosely, thus improving the precision of the conductive component 10Q. Furthermore, the two clamping arms 105 are symmetrically arranged along the diameter direction of the through hole 103, which makes the force on the contact member 11 more uniform and avoids the contact member 11 from deflecting or tilting. The abutment portion 1051 formed at the opening 1031 is an arc surface. Compared with the non-arc surface structure of the abutment portion 1051 formed by bending in the prior art, the arc surface of the abutment portion 1051 is more compatible with the circular structure of the contact section 111, which is more conducive to improving the stable abutment between the abutment portion 1051 and the contact section 111.

[0034] like Figure 5 and Figure 7 As shown, the elastic element 12 is housed in the through hole 103 of the conductive element 10. The elastic element 12 has the elasticity to extend and retract vertically. In this embodiment, the elastic element 12 is a spring.

[0035] like Figure 7 As shown, the conductive component 10Q also includes a signal line 14 assembled from the second end 102 into the through hole 103. The signal line 14 abuts against the side of the elastic member 12 away from the contact member 11 in the vertical direction. Compared to setting a plug in the through hole 103 or riveting a protrusion on the inner wall of the through hole 103 to abut against the elastic member 12, directly abutting against the elastic member 12 through the signal line 14 simplifies the manufacturing process and reduces the overall length of the conductive member 10 in the vertical direction, thereby reducing the resistance of the conductive component 10Q itself, reducing signal attenuation during transmission, and improving the integrity of signal transmission.

[0036] like Figure 13As shown, in other embodiments, the conductive component 10Q further includes a conductive plug 13 housed in the through hole 103. The conductive plug 13 is positioned by interference with the inner wall of the through hole 103 to divide the through hole 103 into two spaced receiving holes 1032 along the vertical direction. One receiving hole 1032 near the opening 1031 is used to house the elastic member 12 and the contact member 11. The side of the elastic member 12 away from the contact member 11 along the vertical direction abuts against the conductive plug 13. The other receiving hole 1032 away from the opening 1031 is used to house the signal line 14. The conductive plug 13 divides the through hole 103 into two receiving holes 1032 (unlabeled), and the two receiving holes 1032 respectively house the signal line 14 and the elastic member 12, avoiding mutual interference between the elastic member 12 and the signal line 14. Specifically, the conductive plug 13 is a spherical conductor. The conductive plug 13 is fixed to the inner wall of the through hole 103 by hard interference, eliminating the need for additional blocking structures, thus simplifying the manufacturing of the conductive component 10Q.

[0037] like Figure 2 , Figure 9 and Figure 10As shown, the base 10R includes a conductive body 17, an elastic conductive base 18, and multiple insulating members 19. The conductive body 17 has multiple receiving grooves 171 that penetrate the conductive body 17 in the vertical direction. The multiple insulating members 19 are assembled one-to-one with each other in the vertical direction toward the first side 1R1 in the multiple receiving grooves 171. Each insulating member 19 has at least one receiving slot 191. The conductive component 10Q is received in the receiving slot 191 for signal transmission. The receiving groove 171 includes a first groove 1711, a second groove 1712, and a limiting part 1713. The first groove 1711 is closer to the first side 1R1 in the vertical direction than the second groove 1712. The first groove 1711 is vertically connected to the second groove 1712. The second groove 1712 is expanded outward in the vertical direction relative to the first groove 1711, thereby forming an annular step-shaped limiting part 1713 at the upper end of the first groove 1711. The insulating member 19 is provided with a mating part 192 corresponding to the limiting part 1713. Specifically, the upper section of the insulating member 19 protrudes outward relative to the lower section, thereby forming a stepped mating part 192. The mating part 192 and the limiting part 1713 cooperate to stop the insulating member 19 in the assembly direction of the insulating member 19. The first segment P1 and the second segment P2 of the conductive component 10 are respectively housed in the first groove 1711, and the third segment P3 of the conductive component 10 is respectively housed in the second groove 1712. If the distance between the third segment P3 and the groove wall of the first groove 1711 is much larger than the distance between the first segment P1 and the second segment P2 and the groove wall of the first groove 1711, the impedance of the third segment P3 will be relatively high. Due to the skin effect at high frequencies, the larger the outer diameter of the conductive component 10, the lower the impedance of the conductive component 10 will be. By setting the outer diameter of the third segment P3 to be larger than the outer diameter of the first segment P1 and the outer diameter of the second segment P2, the impedance of the third segment P3 of the conductive component 10 is reduced, thereby making the overall impedance of the conductive component 10Q more matched. By setting the outer diameter of the first segment P1 to be larger than the outer diameter of the second segment P2, the conductive component 10 can be fixed by interference with the inner wall of the receiving groove 191 of the insulating component 19, so that the conductive component 10 is stably fixed in the receiving groove 191. In this embodiment, the conductive body 17 is formed by stacking two metal plates one on top of the other. The first groove 1711 and the second groove 1712 are respectively formed on the two metal plates one-to-one, which facilitates the manufacturing of the conductive body 17. In other embodiments, the conductive body 17 can also be formed by stacking multiple metal sheets (unlabeled) one on top of the other, which facilitates the manufacturing of the conductive body 17. Of course, the conductive body 17 can also be a one-piece structure, formed by other molding processes.A flexible conductive base 18 is disposed on the lower side of the conductive body 17. The first side 1R1 of the base body 10R is disposed on the flexible conductive base 18, and the flexible conductive base 18 surrounds the insulating member 19. When the connector 100 mates with the mating member 200, the flexible conductive base 18 tightly fits the mating member 200, achieving an electrical connection between the conductive body 17 and the mating member 200, forming a grounding path, preventing signal leakage from the gap between the conductive body 17 and the mating member 200, reducing signal crosstalk, and improving the shielding effect of the connector 100. Specifically, the flexible conductive base 18 is made of conductive rubber. In this embodiment, each insulating element 19 is provided with two receiving slots 191 and a connecting slot 193. The two receiving slots 191 are used to receive two conductive components 10Q that transmit differential signals. The connecting slot 193 penetrates the insulating element 19 in the vertical direction and connects the two receiving slots 191. This reduces the insulating material around the conductive components 10Q, so that part of the dielectric around the conductive components 10Q changes from insulating material to air. Since the dielectric constant of air is lower than that of plastic, the dielectric constant around the conductive components 10Q is reduced, thereby reducing the capacitance of the conductive components 10Q and increasing the characteristic impedance. This facilitates the adjustment of the impedance matching of the conductive components 10Q and improves the high-frequency performance of the connector 100. In other embodiments, the conductive body 17 and the elastic conductive base 18 can be designed as a single conductive integral structure, or each insulating element 19 can have a receiving slot 191.

[0038] like Figure 3 and Figure 10 As shown, the connector 100 includes at least one cable 10M. Each cable 10M includes two signal lines 14, an insulating layer 15 covering each signal line 14, and a shielding layer 16 covering the two signal lines 14. The lower end of the signal line 14 is inserted into the through hole 103 of the conductive member 10 and connected to the conductive member 10. The signal line 14 is part of the conductive component 10Q. In this embodiment, the connector 100 has multiple cables 10M. In other embodiments, the connector 100 may have only one cable 10M.

[0039] like Figure 2 , Figure 4 and Figure 10As shown, the base 10R also includes at least one elastic conductor 20 and a conductive body 22. The conductive body 22 is located above the conductive body 17, and the second side 1R2 is disposed on the conductive body 22. The conductive body 22 is provided with at least one assembly groove 221 for the elastic conductor 20 to be inserted. The assembly groove 221 is arranged vertically and vertically with the receiving groove 171 to facilitate the assembly of the conductive component 10Q. Each elastic conductor 20 is provided with a mounting groove 201, which extends through the elastic conductor 20 in the vertical direction. The cable 10M is installed in the mounting groove 201. The shielding layer 16 is electrically connected to the elastic conductor 20. The mounting groove 201 extends beyond the shielding layer 16 in the vertical direction toward the first side 1R1, so that a receiving space 2012 is formed on one side of the shielding layer 16. The signal line 14 is exposed outside the insulating layer 15 along the vertical direction toward the first side 1R1, and part of the signal line 14 is exposed in the receiving space 2012. Part of the signal line 14 protrudes out of the receiving space 2012 and is inserted into the corresponding through hole 103. The receiving space 2012 is filled with insulating glue 21 so that the signal line 14 is electrically isolated from the elastic conductor 20. Each elastic conductor 20 has at least one annular stop portion 2011 protruding inward from the mounting groove 201. The annular stop portion 2011 abuts against the shielding layer 16. The receiving space 2012 is located on the side of the annular stop portion 2011 closer to the first side 1R1 in the vertical direction. The annular stop portion 2011 is used to block the insulating adhesive 21 in the vertical direction. Specifically, in this embodiment, two annular stop portions 2011 are provided, and the two annular stop portions 2011 are arranged vertically at intervals. Each elastic conductor 20 has an injection hole 2013 and an overflow hole 2014. Both the injection hole 2013 and the overflow hole 2014 are connected to the receiving space 2012. The insulating adhesive 21 is injected into the elastic conductor 20 through the injection hole 2013, and the overflow hole 2014 is used to allow the insulating adhesive 21 to overflow. During connector 100 assembly, cable 10M can be assembled onto elastic conductor 20 first, and signal line 14 can be assembled into conductive component 10. Then, insulating glue 21 is injected through injection hole 2013, so that elastic conductor 20 is filled with insulating glue 21, improving the insulation between signal line 14 and elastic conductor 20. Conductive body 22 can be first sleeved on the side of elastic conductor 20 away from injection hole 2013 and overflow hole 2014 in the vertical direction. After insulating glue 21 is injected into receiving space 2012, conductive body 22 is moved towards injection hole 2013 and overflow hole 2014 in the vertical direction, so that conductive body 22 is blocked outside injection hole 2013 and overflow hole 2014.In this embodiment, the conductive body 22 is provided with multiple assembly slots 221. Two adjacent assembly slots 221 are connected in a direction perpendicular to the vertical direction. Specifically, some two adjacent left and right assembly slots 221 are connected in the left and right direction, while two adjacent front and back assembly slots 221 are not connected. The elastic conductors 20 carrying the cable 10M are assembled one-to-one in the assembly slots 221. The shielding layer 16 of the cable 10M and the conductive body 22 are electrically connected through the elastic conductors 20. The elastic conductors 20 in two adjacent assembly slots 221 are in contact with each other and are connected. In this way, the multiple elastic conductors 20 arranged in the left and right direction are assembled more compactly, which can save space in the left and right direction of the connector 100. Of course, it is also possible to arrange two adjacent front and back and two adjacent left and right assembly slots 221 to be unconnected.

[0040] like Figure 2 and Figure 12 As shown, the base 10R also includes a limiting member 23, which is formed by stamping a metal sheet. The limiting member 23 is located between the conductive body 17 and the conductive body 22 in the vertical direction, and is electrically connected to the conductive body 17 and the conductive body 22. The limiting member 23 includes a base 231, which is connected to the conductive body 17. The limiting member 23 has multiple openings 232 that penetrate the base 231 in the vertical direction. The multiple openings 232 are corresponding to multiple receiving grooves 171 in the vertical direction. Adjacent openings 232 are separated by a limiting part 233. The limiting part 233 blocks one side of the receiving groove 171 in the vertical direction to prevent the insulating member 19 from exiting the receiving groove 171. The limiting part 233 is elastic in the vertical direction so that when the insulating member 19 is assembled into the corresponding receiving groove 171, the limiting part 233 can make way for the insulating member 19 through elastic deformation.

[0041] In summary, the conductive component 10Q and connector 100 of the present invention have the following beneficial effects: (1) In this invention, the conductive element 10 of the conductive component 10Q is formed by turning a through hole 103 through the first end 101 and the second end 102, and an inwardly contracted opening 1031 is formed at the first end 101 of the through hole 103. Therefore, the size of the opening 1031 is manufactured more precisely. Compared with the prior art where the clamping arm 105 of the conductive component 10 is bent to form an abutment part 1051, the abutment part 1051 formed at the position of the clamping arm 105 facing the opening 1031 in this invention generates a more stable force when it abuts the clamping contact section 111. This can prevent the clamping arm 105 from clamping the contact section 111 too tightly or too loosely, thereby improving the precision of the conductive component 10Q. As a result, the clamping force on the contact 11 of the multiple conductive components 10Q in the connector 100 remains highly consistent, thereby improving the precision of the entire connector 100.

[0042] (2) The two clamping arms 105 are symmetrically arranged along the diameter direction of the through hole 103, so that the contact member 11 is subjected to more uniform force. The abutting part 1051 is an arc surface facing the opening 1031. The arc surface is adapted to the shape of the contact section 111, which is conducive to the stable abutting part 1051 and the contact section 111.

[0043] (3) The thickness of the clamping arm 105 from the root 1052 to the abutment 1051 gradually decreases toward the first end 101 in the first direction, thereby making the clamping arm 105 more elastic near the opening 1031, which is conducive to the clamping arm 105 being pushed outward by the contact section 111, and conducive to the contact section 111 moving in the first direction.

[0044] (4) The third segment P3 of the conductive component 10 is housed in the second groove 1712. If the distance between the third segment P3 and the groove wall of the first groove 1711 is much larger than the distance between the first segment P1 and the second segment P2 and the groove wall of the first groove 1711, the impedance of the third segment P3 will be relatively high. Due to the skin effect at high frequency, the larger the outer diameter of the conductive component 10, the lower the impedance of the conductive component 10 will be. The outer diameter of the third segment P3 is larger than the outer diameter of the first segment P1 and the second segment P2. Reducing the difference between the two distances can reduce the impedance of the third segment P3, making the overall impedance of the conductive component 10 more matched, thereby improving the high frequency performance of the conductive component 10Q.

[0045] (5) The conductive plug 13 and the inner wall of the through hole 103 are positioned by interference, without the need for additional blocking structures, which makes the manufacturing of the conductive component 10Q simpler. The conductive plug 13 divides the through hole 103 into two receiving holes 1032. The two receiving holes 1032 respectively receive the signal line 14 and the elastic member 12. When assembling the conductive component 10Q, the conductive member 10, the elastic member 12, the contact member 11 and the conductive plug 13 can be assembled together, while the signal line 14 can be assembled with other structures. Finally, the signal line 14 is assembled into the conductive member 10, thereby speeding up the assembly efficiency of the connector 100.

[0046] (6) The signal line 14 abuts against the side of the elastic member 12 away from the contact member 11. Compared with setting a plug in the through hole 103 or riveting a protrusion on the inner wall of the through hole 103 to abut against the elastic member 12, the manufacturing process is simpler by directly abutting the elastic member 12 through the signal line 14. It can also reduce the overall length of the conductive member 10 in the first direction, thereby reducing the resistance of the conductive component 10Q itself, reducing the signal attenuation during the transmission process, and improving the integrity of the signal transmission.

[0047] (7) By setting the elastic conductive seat 18 around the insulating part 19 and closely fitting the mating part 200, the signal is prevented from leaking from the gap between the first conductive seat and the mating part 200, signal crosstalk is reduced, and the shielding effect of the connector 100 is improved.

[0048] (8) The receiving slot 191 for accommodating the two conductive components 10Q for transmitting differential signals is connected by a connecting slot 193 to reduce the insulating material around the conductive component 10Q, so that part of the medium around the conductive component 10 is changed from insulating material to air. Since the dielectric constant of air is less than that of plastic, the dielectric constant around the conductive component 10Q is reduced, thereby reducing the capacitance of the conductive component 10Q, increasing the characteristic impedance, and keeping the impedance of the conductive component 10Q within the specified range, which is beneficial to improving the high-frequency performance of the connector 100.

[0049] (9) An elastic conductor 20 is provided between the metal layer of the cable 10M and the groove wall of the second receiving groove 171, which can stably fix the cable 10M to the second receiving groove 171. The elastic conductor 20 can form an elastic contact with the metal layer and the groove wall of the second receiving groove 171, so that the metal layer and the conductive body 22 are tightly attached through the elastic conductor 20 to form a stable common ground connection, thereby improving the overall shielding effect of the connector 100.

[0050] (10) An insulating adhesive 21 is filled between the signal line 14 exposed outside the insulating layer 15 and the elastic conductor 20 to ensure electrical isolation between the signal line 14 and the elastic conductor 20. The annular stop portion 2011 blocks the insulating adhesive 21 in the first direction to form a sealing structure, so that the elastic conductor 20 located on the side of the annular stop portion 2011 away from the insulating adhesive 21 in the first direction can form a stable electrical connection with the metal layer, and avoid the insulating adhesive 21 from affecting the electrical connection between the elastic conductor 20 and the metal layer.

[0051] (11) An injection hole 2013 and an overflow hole 2014 are provided on the elastic conductor 20. The cable 10M can be assembled into the elastic conductor 20 first, and the signal line 14 can be assembled into the conductive component 10. Then, the insulating glue 21 is injected from the injection hole 2013, so that the elastic conductor 20 is filled with insulating glue 21, thereby improving the insulation between the signal line 14 and the elastic conductor 20.

[0052] (12) A limiting member 23 is provided on one side of the conductive body 17, and the limiting part 233 of the limiting member 23 is provided to block one side of the receiving groove 171 in the first direction, so that the insulating member 19 is blocked and limited by the limiting part 233 after being assembled into the receiving groove 171, preventing the insulating member 19 from exiting the receiving groove 171 in the first direction.

[0053] 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.
