Abstract
Description
Technical Field
[0001] This invention relates to an electrical connector and an electronic device, and more particularly to an electrical connector that can improve the overall characteristic impedance matching of conductive terminals and an electronic device having the electrical connector. Background Technology
[0002] Existing electrical connectors typically use probes for signal transmission. The probe consists of a tube, a spring housed within the tube, and a needle tip. One end of the spring abuts against the needle tip, allowing the needle tip to move axially relative to the tube; one end of the needle tip protrudes from the tube, serving as the contact end with the mating component, typically forming a point contact or a small-area contact. The needle tip is electrically connected to the tube, and the other end of the tube is connected to a printed circuit board (PCB) via soldering or crimping. This structure results in an impedance mismatch between the probe's two ends and its central portion, causing reflections and distortions along the signal transmission path, ultimately leading to a decrease in signal transmission integrity.
[0003] Therefore, it is necessary to design an electrical connector to solve the above-mentioned technical problems. Summary of the Invention
[0004] The purpose of this invention is to provide an electrical connector and an electronic device having the electrical connector to improve signal transmission integrity.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An electrical connector includes: a base having a plurality of signal receiving slots; a plurality of signal terminals received in the plurality of signal receiving slots, each signal terminal comprising: a tube, at least one contact, and a resilient member, the tube extending longitudinally in a vertical direction, the resilient member and the contact being received in the tube, one end of the resilient member abutting the contact, the contact being movable vertically relative to the tube, and the contact having a contact portion protruding from the tube; and a plurality of adjustment structures circumferentially arranged around the tube, each signal terminal having two adjustment structures, defined as an upper adjustment structure and a lower adjustment structure, the upper adjustment structure circumferentially arranged around the upper end of the tube, and the lower adjustment structure circumferentially arranged around the lower end of the tube, the upper and lower adjustment structures being electrically connected to the tube, used to increase the local thickness of the tube to adjust the local impedance of the signal terminal, such that, in a direction perpendicular to the vertical direction, for the same signal terminal, the portion of the corresponding adjustment structure on it protrudes outward relative to the tube between the upper and lower adjustment structures.
[0006] Furthermore, the adjusting structure and the pipe fitting are separately formed structures and form a ring structure. The adjusting structure is sleeved on the outer surface of the pipe fitting, and the adjusting structure is at least partially in contact with the pipe fitting to achieve electrical conduction.
[0007] Furthermore, the adjusting structure is a rolled structure formed by rolling up a metal sheet, with a first gap formed between the two ends of the adjusting structure along the rolling direction, or the adjusting structure is a set of ring structures formed by directly cutting a metal tube.
[0008] Furthermore, the inner side of the self-adjusting structure has at least one protrusion protruding inward, and each protrusion abuts against the outer surface of the pipe to achieve electrical conduction.
[0009] Furthermore, the adjustment structure and the pipe are integrally formed, and the adjustment structure and the pipe are formed by stamping and rolling metal sheets of different thicknesses.
[0010] Furthermore, the pipe fitting is provided with at least one groove, which is provided along the vertical direction of the pipe fitting. The contact member has at least one slider that protrudes outward in one direction and extends into the groove. The pipe fitting is a rolled structure formed by rolling metal sheet. A second gap is formed between the two ends of the pipe fitting along the rolling direction. One of the grooves is formed at the second gap. At least one of the upper end or the lower end of the groove is provided with a stop. The slider of the contact member is used to abut against the side of the stop that is away from the contact portion of the contact member.
[0011] Furthermore, at least one protective plate is provided in the middle of the chute. The protective plate extends from one side wall of the chute to the other side wall of the chute. The protective plate is used to cover the elastic element to prevent the elastic element from protruding horizontally outward from the chute under force.
[0012] Furthermore, when the contact element moves relative to the tube to the position of maximum compression stroke, the slider is spaced apart from the guard plate in the vertical direction.
[0013] Furthermore, the pipe fitting includes an upper pipe body, a lower pipe body, and multiple connecting sections distributed circumferentially along the pipe fitting. The two ends of the connecting sections are connected to the upper pipe body and the lower pipe body. The upper adjustment structure is sleeved on the outer surface of the upper pipe body, and the lower adjustment structure is sleeved on the outer surface of the lower pipe body.
[0014] Furthermore, the two ends of the upper tube body along the winding direction are fixed together by welding, and the two ends of the lower tube body along the winding direction are fixed together by welding.
[0015] Furthermore, multiple abutting protrusions are provided on the inner wall of the signal receiving groove, and the abutting protrusions abut against the connection section of the corresponding signal terminal.
[0016] Furthermore, the pipe fitting is formed by stamping and rolling metal sheet. When the pipe fitting is unfolded, any two adjacent connecting sections are spaced apart and an opening is formed between them. The pipe fitting is provided with at least one or more protective plates at the middle position of the opening in the vertical direction. Each protective plate extends from one side of one of the openings to the other side of the opening. The protective plates are used to cover the elastic element to prevent the elastic element from being forced to bulge out of the pipe fitting horizontally from the groove.
[0017] Furthermore, each connecting segment is provided with an abutment portion, which protrudes from the upper and lower pipe bodies in a direction perpendicular to the vertical direction of the pipe fitting. Multiple abutment protrusions protrude from the inner wall surface of the signal receiving groove, and each abutment protrusion abuts against the abutment portion of at least one connecting segment.
[0018] Furthermore, when the contact element moves relative to the pipe to the position of maximum compression stroke, the contact part protrudes from the pipe in the vertical direction, and the height of the contact part protruding from the pipe is no more than 0.05mm.
[0019] Furthermore, the signal terminal includes two contacts, which are coiled structures formed by rolling metal sheets. The two contacts are defined as an upper contact and a lower contact. The upper contact has an upper conductive portion and at least one upper contact portion connected to the upper conductive portion. The upper conductive portion is housed in an upper tube and moves vertically relative to the upper tube. At least a portion of the upper contact portion protrudes upward from the upper tube.

Both the upper and lower conductive portions are cylindrical. The upper contact has a contact portion relative to the upper conductive portion. The upper contact member has two inwardly protruding lugs, which are distributed laterally on opposite sides of the upper guide portion and abut against the corresponding side of the upper end of the elastic member. The lower contact member has two inwardly protruding lugs, which are distributed laterally on opposite sides of the lower guide portion and abut against the corresponding side of the lower end of the elastic member. A first height difference is provided between the two upper lugs in the vertical direction, so that the upper contact member is inclined and abuts against the inner wall surface of the pipe. A second height difference is provided between the two lower lugs in the vertical direction, so that the lower contact member is inclined and abuts against the inner wall surface of the pipe.
[0020] Furthermore, the signal terminal includes two contacts, which are coiled structures formed by rolling metal sheets. The two contacts are defined as an upper contact and a lower contact. The elastic element is a spring, which includes a main body section and two contraction sections. The upper and lower ends of the main body section are respectively connected to a contraction section. The contraction sections are housed in the contacts. In the direction perpendicular to the up and down direction, the width of the contraction section is smaller than the width of the main body section.
[0021] Furthermore, the electrical connector also includes multiple grounding terminals, which are pogo pins or stamped terminals. The base includes a metal base, which is formed by stacking metal sheets. Multiple through slots are provided on the metal base, and at least one signal terminal or grounding terminal is accommodated in the through slots. The signal terminal is electrically isolated from the metal base by insulating material, and the grounding terminal is conductive to the metal base.
[0022] Furthermore, the signal receiving slot includes a first slot, a second slot, and a third slot arranged sequentially from top to bottom. The first slot and the third slot are both horizontally protruding outward relative to the second slot, so that the signal receiving slot forms a structure that is large at both ends and small in the middle. The upper adjustment structure is received in the first slot, and the lower adjustment structure is received in the third slot.
[0023] This embodiment also proposes an electronic device, including: two mating parts; and an electrical connector as described above, the electrical connector being electrically connected to the two mating parts.
[0024] Compared with the prior art, the electrical connector designed in this invention has the following advantages: In this invention, each signal terminal is equipped with two adjustment structures, defined as an upper adjustment structure and a lower adjustment structure. The upper adjustment structure is arranged circumferentially around the upper end of the tube, and the lower adjustment structure is arranged circumferentially around the lower end of the tube. The upper and lower adjustment structures are electrically connected to the tube. By using the added upper and lower adjustment structures to increase the local thickness of the upper and lower ends of the tube, the cross-sectional area at the upper and lower ends of the tube is increased. During the current flow through the tube, the local impedance at the upper and lower ends of the tube is reduced, so that the impedance at the upper and lower ends of the tube and the impedance at the middle of the tube are both within the impedance specification line. This improves the phenomenon of reflection and distortion caused in the signal transmission path, improves the signal transmission integrity of the signal terminal, and gives the electrical connector good high-frequency performance.

[0031] For ease of understanding, we define the Z-axis extension direction as the up-down direction (where the positive Z-axis direction is upward), the Y-axis extension direction as the left-right direction (where the positive Y-axis direction is to the right), and the X-axis extension direction as the front-back direction (where the positive X-axis direction is forward).
[0032] An electronic device of the present invention, such as Figure 1As shown, the invention includes an electrical connector 200 and two mating parts that mate with the electrical connector 200. In this embodiment, one mating part is a circuit board 100, and the other mating part is a chip 300. The electrical connector 200 is mounted downwards on the circuit board 100, and the chip 300 is mounted on the electrical connector 200. The chip 300 is electrically connected to the circuit board 100 through the electrical connector 200. In other embodiments, the mating parts can be other types of electrical components.
[0033] like Figures 2 to 10 As shown, this is a first embodiment of the electrical connector 200 of the present invention. Figures 11 to 17 As shown, this is a second embodiment of the electrical connector 200 of the present invention. Figure 18 As shown, this is a third embodiment of the electrical connector 200 of the present invention; as Figure 19 As shown, this is a fourth embodiment of the electrical connector 200 of the present invention. Figure 20 As shown, this is the fifth embodiment of the electrical connector 200 of the present invention; as Figure 21 The figure shown is a sixth embodiment of the electrical connector 200 of the present invention.
[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the electrical connector 200 includes a base 10, multiple signal terminals 20S, and multiple ground terminals 20G. The base 10 has multiple signal receiving slots 101 and multiple ground receiving slots 102, both penetrating two opposite surfaces of the base 10 along the vertical direction. Each signal terminal 20S is received in one signal receiving slot 101, and each ground terminal 20G is received in one ground receiving slot 102. In this embodiment, both the signal terminals 20S and ground terminals 20G are pogo pins with largely the same terminal structure. The upper ends of each signal terminal 20S and ground terminal 20G abut against the chip 300 for electrical connection, and the lower ends of each signal terminal 20S and ground terminal 20G abut against the circuit board 100 for electrical connection. In other embodiments, the upper ends of the signal terminal 20S and the ground terminal 20G respectively abut against the chip 300 to achieve electrical connection, and the lower ends of the signal terminal 20S or the ground terminal 20G are mounted on the circuit board 100. The lower ends of the signal terminal 20S or the ground terminal 20G can be electrically connected to the circuit board 100 by soldering, crimping or other means.
[0035] like Figure 4 , Figure 5As shown, in this embodiment, the base 10 includes an insulating body 10a and at least one grounding layer 10b. The grounding layer 10b is a metal plate. The insulating body 10a and the grounding layer 10b are integrated through an embedding process. The grounding layer 10b is embedded in the insulating body 10a. The insulating body 10a has multiple signal receiving slots 101 and multiple grounding receiving slots 102. The signal receiving slots 101 and grounding receiving slots 102 penetrate the insulating body 10a vertically. The structures of the signal receiving slots 101 and grounding receiving slots 102 are partially different. Multiple grounding receiving slots 102 are provided around the signal receiving slots 101. The grounding layer 10b is partially exposed in each grounding receiving slot 102, but not in each signal receiving slot 101.
[0036] like Figure 4 As shown, the signal receiving slot 101 includes a first slot 101a, a second slot 101b and a third slot 101c arranged from top to bottom. The first slot 101a and the third slot 101c are both horizontally protruding outward relative to the second slot 101b, so that the signal receiving slot 101 forms a structure with large upper and lower ends and a small middle part.
[0037] like Figure 4 , Figure 5 As shown, each signal receiving slot 101 has a plurality of abutting protrusions 101d protruding from its inner wall surface. The abutting protrusions 101d are formed by protruding inward from the inner wall surface of the signal receiving slot 101. The plurality of abutting protrusions 101d corresponding to each signal receiving slot 101 are spaced apart along its slot periphery. In this embodiment, the abutting protrusions 101d are provided in the second slot 101b, and each abutting protrusion 101d abuts against the outer surface of the corresponding signal terminal 20S. The abutting protrusions 101d provide an installation limit for the signal terminal 20S to be installed into the signal receiving slot 101. As shown in the figure, in this embodiment, the signal receiving groove 101 has three spaced abutment protrusions 101d, which abut against the middle of the tube 1. In other embodiments, the inner wall of the signal receiving groove 101 may have only one abutment protrusion 101d, or it may have two or more spaced abutment protrusions 101d. The specific number of abutment protrusions 302 is not limited. The abutment protrusion 101d may abut against the middle of the signal terminal 20S, or it may abut against the upper or lower end of the signal terminal 20S. The abutment position of the abutment protrusion 101d against the signal terminal 20S is not limited.
[0038] like Figure 6 , Figure 9 and Figure 10As shown, in this embodiment, the grounding terminal 20G uses a pogo pin, which has the same structure as the signal terminal 20S. Please refer to the detailed description of the signal terminal 20S in this embodiment; it will not be repeated here. In other embodiments, the grounding terminal 20G can be a stamped terminal, thus the specific structure of the grounding terminal 20G is not limited. In this embodiment, each signal terminal 20S includes a tube 1, two contacts, and an elastic element 4. Both the contacts and the tube 1 are formed by stamping and rolling metal sheets. The tube 1 has a cylindrical structure and extends longitudinally in the vertical direction. The elastic element 4 is specifically a spring structure. The two contacts are defined as the upper contact 2 and the lower contact 3, respectively. A tube opening (not labeled in the figure) is provided at both the upper and lower ends of the tube 1. The elastic element 4 is installed inside the tube 1 through one of the tube openings. The upper contact 2... The upper contact 2 and the lower contact 3 are installed through the upper opening of the tube 1 and the lower contact 3 are installed through the lower opening of the tube 1. The upper contact 2 and the lower contact 3 abut against the upper and lower ends of the elastic element 4, respectively. The upper end of the upper contact 2 abuts against the chip 300, and the lower end of the lower contact 3 abuts against the circuit board 100. The upper contact 2 and the lower contact 3 can move up and down relative to the tube 1. When both the upper contact 2 and the lower contact 3 are under pressure, they move relative to the tube 1 and move closer to each other, causing the elastic element 4 to undergo elastic deformation. When the pressure on the upper contact 2 and the lower contact 3 is removed, the elastic element 4 returns to its original state and drives the upper contact 2 and the lower contact 3 to move along the tube 1 to achieve reset. In other embodiments, each signal terminal 20S includes a tube 1, a contact and an elastic member 4. The contact and the tube 1 can both be formed by rolling metal sheets or by directly cutting tubing. The tube 1 has a cylindrical structure and extends longitudinally in the vertical direction. One end of the tube 1 is provided with a tube opening (not shown in the figure), and the other end of the tube 1 is directly electrically connected to the circuit board 100 by elastic pressing or welding.
[0039] like Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the electrical connector 200 includes multiple adjustment structures 30. Each signal terminal 20S is equipped with two adjustment structures 30, which are defined as an upper adjustment structure 30a and a lower adjustment structure 30b, respectively. The upper adjustment structure 30a is arranged circumferentially around the upper end of the tube 1, and the lower adjustment structure 30b is arranged circumferentially around the lower end of the tube 1. The upper adjustment structure 30a and the lower adjustment structure 30b are electrically connected to the tube 1. By adding the upper adjustment structure 30a and the lower adjustment structure 30b to the upper and lower ends of the tube 1, in the direction perpendicular to the vertical direction, for the same signal terminal 20S, the portion of the corresponding adjustment structure 30 located between the upper adjustment structure 30a and the lower adjustment structure 30b of the tube 1 protrudes outward relative to the tube 1. The added upper adjustment structure 30a and the lower adjustment structure 30b are used to increase the local thickness of the upper and lower ends of the tube 1, thereby increasing the cross-sectional area of the upper and lower ends of the tube 1. The upper adjustment structure 30a is housed in the first slot 101a, and the lower adjustment structure 30b is housed in the third slot 101c.
[0040] like Figure 6 , Figure 9 and Figure 10As shown, in this embodiment, the upper adjustment structure 30a and the lower adjustment structure 30b are separately formed from the pipe fitting 1, wherein both the upper adjustment structure 30a and the lower adjustment structure 30b are a set of ring structures. In this embodiment, the upper adjustment structure 30a is installed from the upper end of the pipe fitting 1 and sleeved on the outer surface of the pipe fitting 1, and the lower adjustment structure 30b is installed from the lower end of the pipe fitting 1 and sleeved on the outer surface of the lower end of the pipe fitting 1. The upper adjustment structure 30a and the lower adjustment structure 30b are at least partially in contact with the pipe fitting 1 to achieve electrical conduction. By separating the upper adjustment structure 30a and the lower adjustment structure 30b from the pipe fitting 1, it is convenient to sleeve the adjustment structure 30 on the basis of the original signal terminal 20S to adjust the impedance. Alternatively, an adjustment structure 30 of appropriate size can be selected according to the required impedance. Both the upper adjustment structure 30a and the lower adjustment structure 30b are rolled structures formed by rolling metal sheets to facilitate processing and forming. A first gap 301 is formed between the two ends of both the upper and lower adjustment structures 30a and 30b along the rolling direction, giving them a certain elastic deformation capability. When installed on the pipe fitting 1, both the upper and lower adjustment structures 30a and 30b can open and close along the winding direction for installation. Simultaneously, this ensures that the inner walls of the upper and lower adjustment structures 30a and 30b are tightly abutted against the outer surface of the pipe fitting 1, improving the connection stability between the upper and lower adjustment structures 30a and 30b and the pipe fitting 1, and maintaining a stable electrical conductivity between the upper and lower adjustment structures 30a and 30b and the pipe fitting 1. In another embodiment, both the upper adjustment structure 30a and the lower adjustment structure 30b can be formed by directly cutting metal tubing into a set of ring structures. The complete ring structure can provide uniform clamping force and support, which not only reduces the difficulty of manufacturing, but also improves the mechanical strength of the adjustment structure 30.
[0041] like Figure 7 , Figure 8 and Figure 9 As shown, at least one protrusion 302 is provided inwardly from the inner side of the upper adjustment structure 30a and the inner side of the lower adjustment structure 30b, respectively. Each protrusion 302 abuts against the outer surface of the pipe fitting 1 to achieve electrical conduction. The protrusion 302 is formed by stamping one side of a metal sheet onto another side, thereby forming the protrusion 302 on the other side. In this embodiment, three protrusions 302 are provided at intervals, and the three protrusions 302 abut against the outer surface of the pipe fitting 1 respectively.
[0042] like Figure 6 and Figure 9As shown, the tube 1 is a rolled structure formed by stamping and rolling a metal sheet. A second gap 13 is formed between the two ends of the tube 1 along the rolling direction. At least one groove 11 is provided on the tube 1, and the groove 11 is arranged along the vertical direction of the tube 1. One of the grooves 11 is formed at the second gap 13. At least one of the upper and lower ends of the groove 11 is provided with a stop 12. In this embodiment, a stop 12 is provided at both the upper and lower ends of the groove 11.
[0043] like Figure 6 , Figure 9 and Figure 10 As shown, the pipe fitting 1 includes an upper pipe body 14, a lower pipe body 15, and a plurality of connecting segments 16 distributed along the circumference of the pipe fitting 1. The two ends of each connecting segment 16 are connected to the upper pipe body 14 and the lower pipe body 15. The upper pipe body 14, the lower pipe body 15, and the plurality of connecting segments are integrally formed metal plates. When the pipe fitting 1 is unfolded, any two adjacent connecting segments 16 are spaced apart and an opening 17 is formed between them. At least two connecting segments 16 and at least two openings 17 are alternately arranged along the circumference of the pipe fitting 1. In this embodiment, the pipe fitting 1 is provided with three connecting segments 16 and three openings 17, one of which is part of the slide groove 11. Each of the three abutting protrusions 101d protruding in the signal receiving groove abuts against a corresponding connecting segment 16. When the pipe fitting 1 is wound and formed, two of the connecting segments 16 are provided at both ends of the winding direction of the pipe fitting 1, and a second gap 13 is formed between the two connecting segments 16. Of course, in other embodiments, the required number of connecting segments 16 and openings 17 can be provided as needed.
[0044] like Figure 6 , Figure 9 and Figure 10 As shown, at least one protective plate 18 is provided at the middle position of the opening 17 in the vertical direction of the pipe fitting 1. The protective plate 18 extends from one side of the opening 17 to the other side. Correspondingly, at least one protective plate 18 is also provided in the middle of the slide groove 11 of the pipe fitting 1. The protective plate 18 extends from one side wall of the slide groove 11 to the other side wall. In this embodiment, two protective plates 18 are provided in the middle of the slide groove 11. The two protective plates 18 are provided on the two side walls of the middle of the slide groove 11, and the two protective plates 18 face each other towards the middle of the slide groove 11. Similarly, in the extended configuration, two guard plates 18 are provided in the middle of each opening 17. The two guard plates 18 are provided on both sides of the middle of the opening 17, and the two guard plates 18 extend towards the middle of the slide groove 11. When the contact member and the docking member dock, the contact member moves relative to the pipe 1 and compresses the elastic member 4. The guard plate 18 is used to cover the elastic member 4 to prevent the elastic member 4 from deforming and protruding horizontally outward from the slide groove 11 / opening 17 from the pipe 1 when it is under force. Of course, in other embodiments, the required number of guard plates 18 can be provided as needed.
[0045] like Figure 4 and Figure 6 As shown, each connecting segment 16 of the pipe fitting 1 is laterally arched outward, and each connecting segment 16 has an abutment portion 161 at its midpoint in the vertical direction. The abutment portion 161 protrudes from the upper pipe body 14 and the lower pipe body 15 in a horizontal direction perpendicular to the vertical direction of the pipe fitting 1. That is, the abutment portion 161 is the largest part of the laterally arched connecting segment 16, so that the signal terminal 20S has the largest lateral dimension at the midpoint of the vertical direction of the pipe fitting 1. By utilizing the inward elastic deformation of the abutment portion 161, it stably abuts against the inner wall surface of the signal receiving groove 101, which facilitates the installation of the signal terminal 20S in the corresponding signal receiving groove 101. In other embodiments, the connecting segment 16 can be a straight segment structure extending vertically, without the abutment portion 161 protruding outward.
[0046] like Figure 6 , Figure 9 and Figure 10 As shown, the upper contact 2 includes an upper guide portion 21 and at least one upper contact portion 22. The upper guide portion 21 is housed within the upper tube body 14 and can move vertically relative to the upper tube body 14. The upper guide portion 21 is a rolled structure formed by rolling a metal sheet, specifically a cylindrical structure. A third gap 211 is formed between the two ends of the upper contact 2 along the winding direction in the upper guide portion 21. In this embodiment, the upper contact 2 has two upper contact portions 22, which extend upward from the upper end of the upper guide portion 21 and are laterally distributed on opposite sides of the upper guide portion 21. Of course, in other embodiments, one or more upper contact portions 22 may be provided.
[0047] like Figure 4 As shown, the upper guide portion 21 is provided with an upper slider 23 and two upper lugs 212 protruding inward relative to the upper guide portion 21. In this embodiment, there is one upper slider 23. Of course, in other embodiments, there can be two or more upper sliders 23. The two upper lugs 212 on the upper guide portion 21 are distributed on opposite sides of the upper guide portion 21 in the lateral direction, and the two upper lugs 212 respectively abut against the corresponding side of the upper end of the elastic member 4. There is a height difference between the two upper lugs 212 in the vertical direction, which is defined as the first height difference H1.
[0048] like Figure 6 , Figure 9 and Figure 10As shown, the lower contact member 3 includes a lower guide portion 31 and at least one lower contact portion 32. The lower guide portion 31 is housed within the lower tube body 15 and can move downwards relative to the lower tube body 15. The lower guide portion 31 is a rolled structure formed by rolling a metal sheet, specifically a cylindrical structure. A fourth gap 311 is formed between the two ends of the lower contact member 3 along the winding direction in the lower guide portion 31. In this embodiment, the lower contact member 3 has two lower contact portions 32, which extend downwards from the lower end of the lower guide portion 31 and are laterally distributed on opposite sides of the lower guide portion 31. Of course, in other embodiments, one or more lower contact portions 32 may be provided.
[0049] like Figure 4 As shown, the lower guide portion 31 is provided with a lower slider 33 and two lower lugs 312 protruding inward relative to the lower guide portion 31. In this embodiment, the lower guide portion 31 is provided with a lower slider 33 protruding outward in the lateral direction. Of course, in other embodiments, two lower sliders 33 can be provided. The lower guide portion 31 is also provided with two lower lugs 312. The two lower lugs 312 are distributed on opposite sides of the lower guide portion 31 in the lateral direction, and the two lower lugs 312 respectively abut against the corresponding side of the lower end of the elastic member 4. There is a height difference between the two lower lugs 312 in the vertical direction, which is defined as the second height difference H2.
[0050] like Figure 1 and Figure 4 As shown, when the electrical connector 200 is mated with the chip 300 and the circuit board 100, both the upper contact 2 and the lower contact 3 are pressed together and move towards each other in the vertical direction, causing the elastic member 4 to be compressed by force. Because there is a first height difference H1 between the two upper lugs 212 in the vertical direction, the upper contact 2 is tilted and abuts against the inner wall of the tube 1. Because there is a second height difference H2 between the two lower lugs 312 in the vertical direction, the lower contact 3 is tilted and abuts against the inner wall of the tube 1. The two upper contact portions 22 of the same signal terminal 20S elastically abut against the same conductive sheet (not shown) of the chip 300, and the lower contact portion 32 of the same signal terminal 20S elastically abuts against the same gasket (not shown) of the circuit board 100.
[0051] like Figures 11 to 17As shown, the difference between this embodiment and the first embodiment is that: the signal receiving groove 101 has six spaced abutment protrusions 101d; the two upper adjustment structures 30a and the lower adjustment structure 30b are integrally formed with the tube 1. That is, the upper adjustment structure 30a, the lower adjustment structure 30b, and the tube 1 can be integrally formed by stamping and rolling metal sheets of different thicknesses. Specifically, the thickness of the metal sheet in the area where the upper adjustment structure 30a and the lower adjustment structure 30b are located is greater than the thickness of the metal sheet in the area between the upper adjustment structure 30a and the lower adjustment structure 30b, avoiding poor contact and separation between the upper adjustment structure 30a and the lower adjustment structure 30b and the tube 1. At the same time, it can also reduce assembly steps and improve production assembly efficiency. Other structures can be found in the detailed description of the first embodiment.
[0052] like Figure 18 As shown, the difference between this embodiment and the second embodiment is that the two ends of the upper tube 14 along the winding direction are fixed by welding, and the two ends of the lower tube 15 along the winding direction are fixed by welding. In this embodiment, the corresponding stops 12 of the upper tube 14 are formed on both ends of the metal plate on which the upper tube 14 is located along the winding direction. The two ends of the upper tube 14 along the winding direction are fixed together by laser welding to improve the overall structural strength of the tube 1 and prevent deformation of the tube 1 along the winding direction after forming. This technique can be applied to the signal terminal 20S in all embodiments of the present invention. Other structures can be found in the descriptions of the first and second embodiments.
[0053] like Figure 18 As shown, in this embodiment, when the contact member moves relative to the tube 1 to the position of maximum compression stroke, both the upper contact portion 22 and the lower contact portion 32 protrude from the tube 1 in the vertical direction. The height of the upper contact portion 22 and the lower contact portion 32 protruding from the tube 1 is no greater than 0.05 mm. This technique can be applied to the signal terminal 20S in all embodiments of the present invention. In this embodiment, the height of the upper contact portion 22 and the lower contact portion 32 protruding from the tube 1 is 0.05 mm, defined as the protrusion height H3.
[0054] like Figure 18 As shown, in this embodiment, when the upper contact 2 moves relative to the tube 1 to the maximum compression stroke position, the upper slider 23 of the upper contact 2 is spaced apart from the guard plate 18 in the vertical direction. When the lower contact 3 moves relative to the tube 1 to the maximum compression stroke position, the lower slider 33 of the lower contact 3 is spaced apart from the guard plate 18 in the vertical direction, so as to avoid interference between the upper slider 23 of the upper contact 2, the lower slider 33 of the lower contact 3 and the guard plate 18. This technique can be applied to the signal terminal 20S in all embodiments of the present invention.
[0055] like Figure 19As shown, the difference between this embodiment and the first embodiment is that the elastic member 4 includes a main body section 41 and two contraction sections 42. The upper and lower ends of the main body section 41 are respectively connected to a contraction section 42. In the direction perpendicular to the vertical direction, the width of the contraction section 42 is smaller than the width of the main body section 41. The elastic member 4 is specifically a spring structure. The contraction section 42 is provided to facilitate the installation of the elastic member 4 into the pipe fitting 1. The contraction section 42 at the upper end of the main body section 41 is convenient to be housed in the upper contact member 2 during assembly, and the contraction section 42 at the lower end of the main body section 41 is convenient to be housed in the lower contact member 3 during assembly.
[0056] like Figure 20 The fifth embodiment of the electrical connector shown and as follows Figure 21 The sixth embodiment of the electrical connector shown differs from the first embodiment only in the structure of the signal terminal 20S. The differences between the fifth and first embodiments, and between the sixth and second embodiments, lie in the structure of the base 10. In both the fifth and sixth embodiments, the base 10 includes a metal base 10c, formed by stacking metal sheets 103. Adjacent metal sheets 103 are electrically connected. The metal base 10c has multiple through slots 104, each slot 104 accommodating at least one signal terminal 20S or a ground terminal 20G. In the fifth and sixth embodiments... In this example, the through-slot 104 accommodating the signal terminals 20S houses two signal terminals 20S used for transmitting differential signals. An insulating material is provided in the through-slot 104, and a signal receiving groove 101 is formed on this insulating material to accommodate the signal terminals 20S. The signal terminals 20S are electrically isolated from the metal base 10c by the insulating material. The ground terminal 20G is directly housed within the through-slot 104. The through-slot 104 accommodating the ground terminal 20G is equivalent to the aforementioned ground receiving groove 102. The ground terminal 20G at least abuts against the central metal sheet 103 and achieves electrical conductivity. Other structures, such as the signal terminals 20S and the ground terminal 20G, can be found in the detailed description of the first or second embodiment.
[0057] In summary, the electrical connector and electronic device of the present invention have the following beneficial effects: (1) Each signal terminal 20S is provided with two adjustment structures 30, defined as an upper adjustment structure 30a and a lower adjustment structure 30b. The upper adjustment structure 30a is arranged circumferentially around the upper end of the tube 1, and the lower adjustment structure 30b is arranged circumferentially around the lower end of the tube 1. The upper adjustment structure 30a and the lower adjustment structure 30b are electrically connected to the tube 1, so that in the direction perpendicular to the vertical direction, for the same signal terminal 20S, the corresponding adjustment structure 30 is located relative to the tube 1 at the upper adjustment structure 30a and the lower adjustment structure 30b. The portion between b protrudes outward, and the added upper adjustment structure 30a and lower adjustment structure 30b are used to increase the local thickness of the upper and lower ends of the pipe fitting 1, thereby increasing the cross-sectional area of the upper and lower ends of the pipe fitting 1. During the process of current passing through the pipe fitting 1, the local impedance of the upper and lower ends of the pipe fitting 1 is reduced, so that the impedance of the upper and lower ends of the pipe fitting 1 and the impedance of the middle part of the pipe fitting 1 are both within the impedance specification line. This improves the phenomenon of reflection and distortion caused in the signal transmission path and enhances the signal transmission integrity of the signal terminal 20S.
[0058] (2) The upper adjustment structure 30a and the lower adjustment structure 30b are separately molded from the pipe fitting 1, which makes it convenient to install the appropriate adjustment structure 30 on the basis of the original signal terminal 20S according to the required impedance range to adjust the local impedance of the signal terminal 20S, so that the impedance of each part of the signal terminal 20S is within the impedance specification line.
[0059] (3) A first gap 301 is formed between the two ends of the upper adjustment structure 30a and the lower adjustment structure 30b along the curling direction, so that the upper adjustment structure 30a and the lower adjustment structure 30b have a certain elastic deformation capability. When installed on the pipe fitting 1, the upper adjustment structure 30a and the lower adjustment structure 30b can be opened and closed along the winding direction for installation. At the same time, it ensures that the inner wall of the upper adjustment structure 30a and the lower adjustment structure 30b is tightly abutted against the outer surface of the pipe fitting 1, improving the connection stability between the upper adjustment structure 30a and the lower adjustment structure 30b and the pipe fitting 1, so that the upper adjustment structure 30a and the lower adjustment structure 30b and the pipe fitting 1 maintain a stable electrical conduction state.
[0060] (4) The upper adjustment structure 30a and the lower adjustment structure 30b can be formed by directly cutting metal pipes to form a set of ring structures. The complete ring structure can provide uniform clamping force and support, which not only reduces the difficulty of production and manufacturing, but also improves the mechanical strength of the adjustment structure 30. Due to the consistency of the structure, its impedance value is relatively stable.
[0061] (5) At least one protrusion 302 is provided on the inner side of the upper adjustment structure 30a and the lower adjustment structure 30b respectively. Each protrusion 302 abuts against the outer surface of the pipe fitting 1 to achieve electrical conduction, thereby improving the stability of electrical conduction between the upper adjustment structure 30a and the lower adjustment structure 30b and the pipe fitting 1.
[0062] (6) The two upper adjustment structures 30a and the lower adjustment structure 30b are integrally formed with the pipe fitting 1. That is, the upper adjustment structure 30a, the lower adjustment structure 30b and the pipe fitting 1 can be formed by stamping and rolling metal plates of different thicknesses, which avoids poor contact and separation between the upper adjustment structure 30a and the lower adjustment structure 30b and the pipe fitting 1. At the same time, it can also reduce assembly steps and improve production assembly efficiency.
[0063] (7) At least one sliding groove 11 is provided on the pipe fitting 1. The sliding groove 11 is arranged along the vertical direction of the pipe fitting 1. The upper contact member 2 has an upper slider 23 protruding outward in one direction, and the lower contact member 3 has a lower slider 33 protruding outward in one direction. The upper slider 23 of the upper contact member 2 and the lower slider 33 of the lower contact member 3 respectively protrude into the same sliding groove 11. A stop 12 is provided at both the upper and lower ends of the sliding groove 11. The upper slider 23 of the upper contact member 2 abuts against the lower side of the stop 12 at the lower end of the pipe fitting 1, and the lower slider 33 of the lower contact member 3 abuts against the upper side of the stop 12 at the lower end of the pipe fitting 1, so as to avoid the upper slider 23 protruding outward in one direction. Contact 2 and lower contact 3 detach from tube 1; tube 1 is a rolled structure formed by rolling metal sheet, and a second gap 13 is formed between the two ends of tube 1 along the rolling direction. A groove 11 is formed at the second gap 13. This structure does not require material removal by machining to form the groove 11, which can preserve the structural integrity of tube 1 to the greatest extent. It not only enhances the overall structural strength and deformation resistance of tube 1, but also simplifies the processing flow, eliminates additional processes such as cutting and grinding, improves processing efficiency, and reduces material loss and manufacturing costs.
[0064] (8) At least one guard plate 18 is provided in the middle of the slide groove 11. The guard plate 18 extends from one side wall of the slide groove 11 to the other side wall of the slide groove 11. At least one guard plate 18 is provided in the middle of the opening 17 in the vertical direction. The guard plate 18 extends from one side of the opening 17 to the other side of the opening 17. The guard plate 18 is used to protect the elastic member 4 to prevent the elastic member 4 from being subjected to force and protruding horizontally outward from the slide groove 11 or the opening 17 from the pipe 1, so as to avoid the elastic member 4 from being damaged due to large deformation.
[0065] (9) When the upper contact 2 moves relative to the pipe 1 to the maximum compression stroke position, the upper slider 23 is spaced apart from the guard plate 18 in the up and down direction. During the relative up and down movement of the upper contact 2, the upper slider 23 and the guard plate 18 can be prevented from interfering and getting stuck instead of moving up and down smoothly. When the lower contact 3 moves relative to the pipe 1 to the maximum compression stroke position, the lower slider 33 is spaced apart from the guard plate 18 in the up and down direction. During the relative up and down movement of the lower contact 3, the lower slider 33 and the guard plate 18 can be prevented from interfering and getting stuck instead of moving up and down smoothly.
[0066] (10) The fitting 1 includes an upper pipe body 14, a lower pipe body 15 and multiple connecting sections 16 distributed along the circumference of the fitting 1. The two ends of each connecting section 16 are connected to the upper pipe body 14 and the lower pipe body 15. The upper adjustment structure 30a is sleeved on the outer surface of the upper pipe body 14 and the lower adjustment structure 30b is sleeved on the outer surface of the lower pipe body 15. The upper adjustment structure 30a and the lower adjustment structure 30b are respectively sleeved on the outer surfaces of the upper pipe body 14 and the lower pipe body 15, which facilitates the positioning and installation of the upper adjustment structure 30a and the lower adjustment structure 30b, so as to achieve precise adjustment of the local impedance of the signal terminal 20S.
[0067] (11) The upper tube 14 is fixed to the two ends along the winding direction by welding, and the lower tube 15 is fixed to the two ends along the winding direction by welding. This can improve the overall structural strength of the tube 1 and prevent the tube 1 from opening and deforming along the winding direction after forming.
[0068] (12) Multiple abutting protrusions 101d are provided on the inner wall of the signal receiving groove 101. The abutting protrusions 101d abut against the connecting section 16 of the corresponding signal terminal 20S, which facilitates the improvement of the installation and positioning stability between the signal terminal 20S and the signal receiving groove 101.
[0069] (13) The tube 1 is formed by stamping and rolling metal sheet. When the tube 1 is unfolded, any two adjacent connecting segments 16 are spaced apart and an opening 17 is formed between them. By making the tube 1 form a non-closed structure with connecting segments 16 and opening 17 arranged alternately in the circumferential direction, the capacitance of the signal terminal 20S itself can be effectively reduced, and the impedance of the signal terminal 20S in the middle position can be increased, so that it falls within the preset range of impedance. This avoids the low impedance caused by excessive capacitance in the traditional fully enclosed tube 1, and improves the overall signal transmission integrity and data transmission rate of the electrical connector 200.
[0070] (14) Each connecting section 16 is provided with an abutment part 161. The abutment part 161 protrudes from the upper pipe body 14 and the lower pipe body 15 in a vertical direction perpendicular to the pipe 1. The abutment part 161 abuts against the inner wall surface of the signal receiving groove 101. By utilizing the inward elastic deformation of the abutment part 161, it can stably abut against the inner wall surface of the signal receiving groove 101, which facilitates the installation of the signal terminal 20S in the corresponding signal receiving groove 101.
[0071] (15) Multiple abutting protrusions 101d are provided on the inner wall surface of the signal receiving groove 101. Each abutting protrusion 101d abuts against the abutting part 161 of at least one connecting section 16, thereby improving the installation and positioning stability of the signal terminal 20S and the signal receiving groove 101.
[0072] (16) When the contact moves relative to the tube 1 to the position of maximum compression stroke, the upper contact 22 and the lower contact 32 both protrude from the tube 1 in the vertical direction. The height of the upper contact 22 and the lower contact 32 protruding from the tube 1 is no more than 0.05 mm, so as to avoid the tube 1 from contacting the chip 300 or other components on the circuit board 100, causing short circuit or damage.
[0073] (17) The two opposite sides of the upper end of the elastic member 4 abut against the two upper lugs 212 of the upper guide portion 21, and the two upper lugs 212 have a first height difference H1 in the vertical direction. With the help of the elastic member 4, the upper contact member 2 is provided with an inclined lateral force, which causes the upper contact member 2 to be in close contact with the upper tube body 14 at an incline, ensuring that the electrical signal can be stably transmitted from the upper contact member 2 to the upper tube body 14. Similarly, the two opposite sides of the lower end of the elastic member 4 abut against the two lower lugs 312 of the lower guide portion 31, and the two lower lugs 312 have a second height difference H2 in the vertical direction. With the help of the elastic member 4, the upper contact member 2 is provided with an inclined lateral force, which causes the upper contact member 2 to be in close contact with the upper tube body 14 at an incline, ensuring that the electrical signal can be stably transmitted from the upper contact member 2 to the upper tube body 14. The force exerted by the elastic element 4 provides an inclined lateral force to the lower contact element 3, causing the lower contact element 3 to be in close contact with the lower tube body 15 at an inclination, ensuring that the electrical signal can be stably transmitted to the upper tube body 14 through the lower contact element 3; at the same time, the two upper lugs 212 abut against the opposite sides of the upper end of the elastic element 4, and the two lower lugs 312 abut against the opposite sides of the lower end of the elastic element 4, which can enhance the stability of the fit between the elastic element 4 and the upper contact element 2 and the lower contact element 3, effectively preventing the elastic element 4 from detaching from the upper lugs 212 or the lower lugs 312 under pressure, and further improving the reliability of the overall structure.
[0074] (19) The elastic element 4 includes a main body section 41 and two contraction sections 42. The upper end and the lower end of the main body section 41 are respectively connected to a contraction section 42. In the direction perpendicular to the up and down direction, the width of the contraction section 42 is smaller than the width of the main body section 41 so that the elastic element 4 can be installed into the pipe fitting 1. The contraction section 42 at the upper end of the main body section 41 can be accommodated in the upper contact member 2 during assembly, and the contraction section 42 at the lower end of the main body section 41 can be accommodated in the lower contact member 3 during assembly.
[0075] (20) The base 10 is a metal base 10c formed by stacking metal sheets 103. Multiple through slots 104 are provided on the metal base 10c. At least one signal terminal 20S or ground terminal 20G is accommodated in the through slot 104. The signal terminal 20S is electrically isolated from the metal base 10c by insulating material. Each metal sheet 103 in the metal base 10c is a ground plane. After being stacked, it provides excellent shielding effect around the signal terminal 20S, which can greatly reduce electromagnetic interference and amplitude-frequency interference, and at the same time reduce the external radiation of the signal terminal 20S and reduce crosstalk between the signal terminals 20S.
[0076] 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.
