Description

[Technical Field]

[0001] This utility model relates to an electrical connector, and more particularly to an electrical connector with double-sided terminal compression and improved high-frequency performance. [Background Technology]

[0002] A conventional electrical connector for electrically connecting a chip module and a circuit board includes a body and a plurality of conductive terminals assembled on the body. Each conductive terminal has a base with protrusions that interfere with the body to fix the conductive terminal to the body. An upper spring arm extends upward from the upper end of the base, and the upper spring arm is elastically deformable to abut against the chip module. A lower spring arm extends downward from the lower end of the base, and the lower spring arm is elastically deformable to abut against the circuit board. However, to ensure good contact between the upper spring arm and the chip module and between the lower spring arm and the circuit board, the lengths of the upper and lower spring arms need to be relatively long. This results in a longer overall length of the conductive terminals and a larger spacing between the terminals, which is detrimental to the high-frequency and density requirements of the electrical connector. [Utility Model Content]

[0003] The purpose of this invention is to provide an electrical connector in which the terminals can float up and down within the insulating body, thus improving the high-frequency performance of the terminals.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrical connector includes: an insulating body; a plurality of terminals respectively housed in the insulating body; each terminal having a positioning portion for being vertically and horizontally positioned on the insulating body; an upper arc-shaped portion extending upward from the upper end of the positioning portion, the upper arc-shaped portion being connected to an upper contact portion for abutting an upper mating element upward; and a lower arc-shaped portion extending downward from the lower end of the positioning portion, the lower arc-shaped portion being connected to a lower contact portion for abutting a lower mating element downward; the upper contact portion and the lower contact portion are vertically aligned; and the plate surfaces of the positioning portion, the upper arc-shaped portion, and the lower arc-shaped portion are located on the same plane.

[0006] Furthermore, each terminal also has a connecting part for connecting the material strip and a bending part. The connecting part and the bending part protrude from opposite sides of the positioning part. The center of the arc of the connecting part and the upper arc-shaped part are located on opposite sides of the positioning part, and the plate surface of the connecting part and the plate surface of the positioning part are on the same plane. The insulating body is provided with a stop block and a limiting groove for receiving the bending part. The stop block is located below the connecting part to prevent the connecting part from moving downward. The limiting groove penetrates downward through the insulating body, and the upper wall surface of the limiting groove is located above the bending part to prevent the bending part from moving upward.

[0007] Furthermore, the width of the upper arc-shaped portion gradually increases from the upper contact portion to the connecting portion, and the width of the lower arc-shaped portion gradually increases from the lower contact portion to the bending portion, wherein the minimum width of the upper arc-shaped portion is 0.03mm-0.05mm and the maximum width is 0.11mm-0.13mm.

[0008] Furthermore, the positioning part is arc-shaped, and the positioning part shares the same center with the upper arc-shaped part and the lower arc-shaped part.

[0009] Furthermore, the terminal also includes a clearance space, which extends through the upper arc-shaped portion, the positioning portion, and the lower arc-shaped portion in a direction perpendicular to the plate surface. The positioning portion has an upper limit portion and a lower limit portion on one side of the clearance space. The insulating body has a stop block, with the upper limit portion and the lower limit portion located on the upper and lower sides of the stop block. The stop block prevents the upper limit portion from moving excessively downward and prevents the lower limit portion from moving excessively upward. When the terminal abuts against the upper and lower mating elements, the upper limit portion and the lower limit portion can move toward the clearance space, allowing the terminal to float up and down within the insulating body.

[0010] Furthermore, the upper arc-shaped portion protrudes into a connecting portion for connecting the material strip connecting portion, and the connecting portion is located between the upper contact portion and the upper limit portion.

[0011] Furthermore, the plate surface of the positioning part is defined as the front and rear surfaces. The terminal also includes an elastic part connecting the upper arc-shaped part and the lower arc-shaped part. The elastic part and the positioning part are spaced apart in the left and right direction. The upper arc-shaped part, the positioning part, the lower arc-shaped part and the elastic part form an elastic deformation space. When the terminal abuts against the upper docking element and the lower docking element, the elastic part can deform toward the elastic deformation space, so that the terminal can float up and down in the insulating body.

[0012] Furthermore, the insulating body has two positioning surfaces arranged opposite each other for each terminal, and the positioning part and the elastic part abut against the corresponding positioning surface along the left and right direction.

[0013] Furthermore, the elastic part has an arc-shaped segment and two connecting segments located at both ends of the arc-shaped segment. The connecting segments are used to connect the positioning part and the arc-shaped segment, and the arc centers of the arc-shaped segment and the positioning part are located on the same side of the arc-shaped segment.

[0014] Furthermore, the upper arc-shaped portion and the lower arc-shaped portion are arranged symmetrically, and when the terminal abuts against the upper docking element and the lower docking element, the upper contact portion and the lower contact portion are located in the insulating body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The plate surfaces of the positioning portion, the upper arc-shaped portion, and the lower arc-shaped portion are located on the same plane. Therefore, the upper and lower arc-shaped portions of the terminal do not require stamping or bending, resulting in a simple structure that facilitates production and improves high-frequency performance. The positioning portion is vertically floating and confined within the insulating body, thus giving it elasticity. In other words, the conductive terminal is elastic from beginning to end. Therefore, compared to the prior art, while providing the same elasticity, the length of the upper and lower arc-shaped portions can be reduced, thereby reducing the terminal length and benefiting high-frequency performance.

Detailed Implementation Methods

[0031] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0032] For the sake of accuracy, all directions mentioned in this article are defined as follows: the X-axis extends in the forward-backward direction (with the positive X-axis direction being forward), the Y-axis extends in the left-right direction (with the positive Y-axis direction being right), and the Z-axis extends in the up-down direction (with the positive Z-axis direction being up).

[0033] like Figure 1 , Figure 2 As shown, the electrical connector 100 of the first embodiment of the present invention is used to electrically connect an upper docking element 200 and a lower docking element 300 respectively (in this embodiment, the upper docking element 200 is a chip module and the lower docking element 300 is a circuit board); the electrical connector 100 includes an insulating body 1 and a plurality of terminals 2 (for clarity, only some terminals are shown in the figure, but the actual number of terminals is more than this).

[0034] like Figure 1 , Figure 2 As shown, the insulating body 1 is provided with a stop block 11 and a limiting groove 12 corresponding to the terminal 2, and the limiting groove 12 penetrates downward through the insulating body 1.

[0035] like Figure 2 , Figure 3As shown, multiple terminals 2 are respectively housed in an insulating body 1 and can float up and down within the insulating body 1; each terminal 2 has a positioning part 21 for positioning in the insulating body 1, an upper arc-shaped part 22 extending upward from the positioning part 21, the upper arc-shaped part 22 is connected to an upper contact part 23 for abutting the upper docking element 200 upward, a lower arc-shaped part 24 extending downward from the positioning part 21, and the lower arc-shaped part 24 is connected to a lower contact part 25 for abutting the lower docking element 300 downward. In this embodiment, the positioning part 21 is arc-shaped (in other embodiments, the positioning part 21 may also be rectangular or other shapes), and shares the same center with the upper arc-shaped part 22 and the lower arc-shaped part 24. The plate surface of the positioning part 21, the plate surface of the upper arc-shaped part 22, and the plate surface of the lower arc-shaped part 24 are located on the same plane; the upper arc-shaped part 22 and the lower arc-shaped part 24 are arranged symmetrically in the upper and lower directions. Before and after the terminal 2 abuts against the upper docking element 200 and the lower docking element 300, the positioning part 21 abuts against the side of the stop block 11; before the terminal 2 abuts against the upper docking element 200 and the lower docking element 300, the upper contact part 23 and the lower contact part 25 are located outside the insulating body 1; after the terminal 2 abuts against the upper docking element 200 and the lower docking element 300, the upper contact part 23 and the lower contact part 25 are located inside the insulating body 1.

[0036] like Figure 3 , Figure 4 As shown, each terminal 2 also has a connecting part 26 for connecting the strip and a bending part 27. The connecting part 26 and the bending part 27 protrude from opposite sides of the positioning part 21. The arc center of the connecting part 26 and the upper arc-shaped part 22 are located on opposite sides of the positioning part 21, and the plate surface of the connecting part 26 and the plate surface of the positioning part 21 are on the same plane. The stop block 11 is located below the connecting part 26 to prevent the connecting part 26 from moving downward. The bending part 27 bends. The material enters the limiting groove 12, and the upper wall of the limiting groove 12 is located above the bending portion 27, preventing the bending portion 27 from moving upward. In this embodiment, the width of the upper arc-shaped portion 22 gradually increases from the upper contact portion 23 to the connecting portion 26, and the width of the lower arc-shaped portion 24 gradually increases from the lower contact portion 25 to the bending portion 27. The minimum width of the upper arc-shaped portion 22 is 0.03mm-0.05mm, and the maximum width is 0.11mm-0.13mm.

[0037] like Figures 5-8As shown, this is the electrical connector 100 of the second embodiment of the present invention. The difference from the first embodiment is that the insulating body 1 has a stop block 13, and the terminal 2 further includes a clearance space G. The clearance space G extends through the upper arc-shaped portion 22, the positioning portion 21, and the lower arc-shaped portion 24 in a direction perpendicular to the plate surface. The positioning portion 21 is generally vertical, and the positioning portion 21 has an upper limit portion 211 and a lower limit portion 212 on one side of the clearance space G. Figure 6 As shown, the upper limit portion 211 and the lower limit portion 212 are located on the upper and lower sides of the stop block 13, and the stop block 13 prevents the upper limit portion 211 from moving excessively downward and prevents the lower limit portion 212 from moving excessively upward; as Figure 7 As shown, when terminal 2 abuts against upper mating element 200 and lower mating element 300, the upper limit portion 211 and the lower limit portion 212 can move toward the clearance space G, so that terminal 2 can float up and down in the insulating body 1; the connecting portion 26 protrudes from the upper arc-shaped portion 22, and the connecting portion 26 is located between the upper contact portion 23 and the upper limit portion 211.

[0038] like Figures 9-12 As shown, this is the electrical connector 100 of the third embodiment of the present invention. The difference from the first embodiment is that: the insulating body 1 has two positioning surfaces 14 arranged opposite each other in the left-right direction; the terminal 2 further includes an elastic portion 28 connecting the upper arc-shaped portion 22 and the lower arc-shaped portion 24, and is spaced apart from the positioning portion 21 in the left-right direction. The positioning portion 21 and the elastic portion 28 abut against the corresponding positioning surface 14 in the left-right direction. The elastic portion 28 has an arc-shaped segment 281 and two connecting segments 282 located at both ends of the arc-shaped segment 281, as shown... Figure 12 As shown, the connecting segment 282 is used to connect the positioning part 21 and the arc-shaped segment 281. The arc centers of the arc-shaped segment 281 and the positioning part 21 are located on the same side of the arc-shaped segment 281. The width between the left and right sides of the arc-shaped segment 281 gradually increases and then gradually decreases from top to bottom. The upper arc-shaped part 22, the positioning part 21, the lower arc-shaped part 24, and the elastic part 28 form an elastic deformation space Q, as shown. Figure 10 , Figure 11 As shown, when the terminal 2 abuts against the upper docking element 200 and the lower docking element 300, the elastic part 28 can deform toward the elastic deformation space Q, so that the terminal 2 can float up and down in the insulating body 1.

[0039] In summary, this utility model has the following beneficial effects:

[0040] 1. The plate surfaces of the positioning part 21, the upper arc-shaped part 22, and the lower arc-shaped part 24 are located on the same plane. Therefore, the upper arc-shaped part 22 and the lower arc-shaped part 24 of the terminal 2 do not require stamping or bending, resulting in a simple structure that facilitates production and improves high-frequency performance. The positioning part 21 is vertically movable and positioned relative to the insulating body 1, thus giving it elasticity. In other words, the conductive terminal 2 is elastic from beginning to end. Therefore, compared to the prior art, under the premise of providing the same elasticity, the length of the upper arc-shaped part 22 and the lower arc-shaped part 24 can be reduced, thereby reducing the length of the terminal 2 and benefiting high-frequency performance.

[0041] In addition, the terminal 2 can float up and down in the insulating body 1. When the terminal 2 abuts against the upper docking element 200 and the lower docking element 300 respectively, if a certain terminal 2 is too high, the excessively high terminal 2 can move downward, so that the compression amount of the upper arc-shaped part 22 and the lower arc-shaped part 24 of the excessively high terminal 2 is closer; and the area of ​​the upper arc-shaped part 22 or the lower arc-shaped part 24 of each terminal 2 exposed outside the insulating body 1 after compression is approximately the same, so that the overall impedance of the terminal 2 is matched.

[0042] 2. The positioning part 21 is arc-shaped, and the positioning part 21, the upper arc-shaped part 22, and the lower arc-shaped part 24 are concentric, thereby improving the elasticity of the terminal 2.

[0043] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. 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.
