Description

Technical field

[0001] The present invention relates to an electrical connector, and in particular to an electrical connector which optimizes time lag by adjusting impedance. [Background Technology]

[0002] The electrical connector includes two rows of terminals and a shielding member arranged between the two rows of terminals. Each row of terminals includes a differential signal terminal pair for transmitting signals. In conventional designs, in order to ensure the matching of the electrical connector and the docking PCB or docking connector, the structure and position settings of the two rows of terminals and the shielding member inside it often make it impossible to take into account the high-frequency performance of the electrical connector due to excessive consideration of the above-mentioned matching, which ultimately leads to signal distortion. As the requirements for high-speed and high-frequency signal transmission become increasingly stringent, it is necessary to consider how to further improve the high-frequency performance of the electrical connector on the basis of meeting conventional designs. Therefore, it is necessary to design a new electrical connector to overcome the above-mentioned problems. [Summary of the invention]

[0003] In view of the problems faced by the background technology, the invention aims to provide an electrical connector that optimizes time lag and improves signal integrity by adjusting impedance.

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

[0006] Furthermore, the portion of the extension section that extends beyond the second extension portion in a direction away from the shielding main section is defined as a third section. The second conductive section has an end portion, and the end portion is arranged on a side of the second conductive section away from the second extension portion, wherein the third section does not extend beyond the end portion in a direction away from the shielding main section.

[0007] Furthermore, viewed in a direction perpendicular to the extending direction of the second extending portion, the projection of the extending section and the projection of the second guiding portion are completely staggered.

[0008] Furthermore, there is a first angle between the first main body and the first extension portion, and a second angle between the second main body and the second extension portion, wherein the first angle is smaller than the second angle, the first conductive portion and the second conductive portion are in contact with a first element, the first conductive portion includes a first contact surface in contact with the first element, the second conductive portion includes a second contact surface in contact with the first element, and the first contact surface and the second contact surface are located in the same plane.

[0009] Furthermore, the first row of terminals also includes at least one first grounding terminal, the first grounding terminal having a first grounding main body, a first grounding contact portion and a first grounding extension portion extending from both sides of the first grounding main body, and a first grounding conductive portion connected to a side of the first grounding extension away from the first grounding main body; the second row of terminals also includes at least one second grounding terminal, the second grounding terminal having a second grounding main body, a second grounding contact portion and a second grounding extension portion extending from both sides of the second grounding main body, and a second grounding conductive portion connected to a side of the second grounding extension away from the second grounding main body; along the arrangement direction of the first row of terminals, the first grounding terminal is located on one side of the first differential signal pair, and there is a first spacing between the first extension portion and the first grounding extension portion; along the arrangement direction of the second row of terminals, the second grounding terminal is located on one side of the second differential signal pair, and there is a second spacing between the second extension portion and the second grounding extension portion, wherein the first spacing is smaller than the second spacing.

[0010] Furthermore, along the arrangement direction of the first row of terminals, the width of the first extension portion is greater than the width of the first grounding extension portion, along the arrangement direction of the second row of terminals, the width of the second extension portion is equal to the width of the second grounding extension portion, and the width of the first grounding extension portion along the arrangement direction of the first row of terminals is greater than the width of the second grounding extension portion along the arrangement direction of the second row of terminals.

[0011] Furthermore, the electrical connector includes an insulating plug, which includes at least one first partition column and at least one second partition column, wherein a first partition column is located between two adjacent first signal terminals, and a second partition column is located between two adjacent second signal terminals, wherein the first partition column is higher than the second partition column along the arrangement direction perpendicular to the arrangement direction of the first row of terminals or the arrangement direction of the second row of terminals.

[0012] Furthermore, the electrical connector includes an insulating plug, which includes multiple partition columns. A first signal terminal is located between two adjacent partition columns. Along the arrangement direction of the first row of terminals, a partition column between two first signal terminals in the first differential signal pair is provided with a clearance groove, and the facing portions of the two first extensions are located in the same clearance groove.

[0013] Furthermore, the electrical connector includes an insulating plug, which includes a plurality of partition columns, the partition columns including a first partition column and a third partition column, and along the arrangement direction of the first row of terminals, the first partition column is located between two first signal terminals in the first differential signal pair, wherein, along the arrangement direction of the first row of terminals, the width of the first partition column is smaller than the width of the third partition column, and the gap between the two first extensions is larger than the width of the first partition column.

[0014] Furthermore, the electrical connector includes an insulating plug, which includes multiple partitions. A horizontal partition is arranged between two adjacent partitions along the arrangement direction perpendicular to the first row of terminals, and the horizontal partition connects the two partitions. Along the arrangement direction perpendicular to the first row of terminals, the horizontal partition gradually narrows from the first extension portion to the first conductive portion.

[0015] Furthermore, the electrical connector includes an insulating plug, which includes a limiting surface and a substrate; the limiting surface is located on the side of the extension section away from the shielding main section, and is spaced apart from the end surface, and there is a third distance between the limiting surface and the end surface; the substrate is located on the side of the first conductive portion away from the first main body portion, and is spaced apart from the first conductive portion, and there is a fourth distance between the first conductive portion and the substrate, wherein the third distance is smaller than the fourth distance.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The length of the first extension portion in its extension direction is greater than the length of the second extension portion in its extension direction, so the inductance at the first extension portion is greater than the inductance at the second extension portion. Furthermore, the portion of the first extension portion that extends beyond the end surface in a direction close to the first conductive portion is defined as a first segment, and the portion of the second extension portion that extends beyond the end surface in a direction close to the second conductive portion is defined as a second segment, or does not extend beyond the end surface. In the present application, the length of the first segment is set to be greater than the length of the second segment. In other words, the capacitive coupling between the first extension portion and the extension segment is less than the capacitive coupling between the second extension portion and the extension segment, so that the impedance of the first signal terminal at the first extension portion is greater than the impedance of the second signal terminal at the second extension portion. The present application also sets the width of the first extension portion to be greater than the width of the second extension portion, so that the impedance at the first extension portion matches the impedance at the second extension portion. In other words, the width of the first extension portion is greater than the width of the second extension portion, so that the inductance of the first extension portion is reduced, thereby reducing the impedance at the first extension portion, and ultimately optimizing the time lag between the first differential signal pair and the second differential signal pair caused by the impedance difference between the first extension portion and the second extension portion, thereby facilitating signal transmission and improving the signal integrity performance of the electrical connector.

[0032] like Figure 2As shown, the Type-C connector of the present invention also includes a metal shell 6 arranged on the outside of the insulating body 1, specifically, including an inner shielding shell 61 and an upper shell 62 and a lower shell 63 separately arranged on the outside of the inner shielding shell 61. The insulating body 1 actually includes a first insulating member 11 molded on the first row of terminals 2, a second insulating member 12 molded on the second row of terminals 3, and a third insulating member 13 molded on the outside of the first insulating member 11 and the second insulating member 12. The shielding member 4 can be accommodated in the insulating body 1 in different ways, for example, molded in the first insulating member 11 together with the first row of terminals 2, or molded in the second insulating member 12 together with the second row of terminals 3, or clamped between the first insulating member 11 and the second insulating member 12 and then molded together in the third insulating member 13.

[0033] The first row of terminals 2 and the second row of terminals 3 are electrically connected to the first component 200 by surface elastic abutment and are fixed to the first component 200 by bolts. Of course, in other embodiments, other conventional technical means can also be used for electrical connection, such as but not limited to surface welding, through-hole welding or solder-free fisheye foot method, etc.

[0034] like Figure 6 As shown, the first row of terminals 2 includes two first differential signal pairs 21 and a first ground terminal 22 located on the left or right side of each first differential signal pair 21; each first differential signal pair 21 includes two first signal terminals 21a adjacent to each other on the left and right sides, and each first signal terminal 21a has a first main body 211, a first contact portion 212 extending forward from the first main body 211, a first extension portion 213 extending backward from the first main body 211, and a first conductive portion 214 extending backward from the first extension portion 213; wherein a first angle R1 is formed between the first main body 211 and the first extension portion 213. In this embodiment, the first angle R1 is an obtuse angle greater than 90 degrees but less than 180 degrees. Of course, in other embodiments, other angles can also be selected according to needs.

In the left-right direction, a first spacing H1 exists between the first extension portion 213 and the first grounding extension portion 223, and the width of the first extension portion 213 is greater than the width of the first grounding extension portion 223.

[0036] like Figure 6As shown, the second row of terminals 3 includes two second differential signal pairs 31 and a second ground terminal 32 located on the left or right side of each second differential signal pair 31. Each second differential signal pair 31 includes two second signal terminals 31a adjacent to each other on the left and right sides. Each second signal terminal 31a has a second main body 311, a second contact portion 312 extending forward from the second main body 311, a second extension portion 313 extending rearward from the second main body 311, and a second conductive portion 314 extending rearward from the second extension portion 313. A second angle R2 is formed between the second main body 311 and the second extension portion 313. In this embodiment, the second angle R2 is an obtuse angle greater than 90 degrees but less than 180 degrees. It is worth noting that in the present invention, the first angle R1 is also set to be smaller than the second angle R2.

[0037] The second grounding terminal 32 includes a second grounding body portion 321, a second grounding contact portion 322 extending forward from the second grounding body portion 321, a second grounding extension portion 323 extending backward from the second grounding body portion 321, and a second grounding conductive portion 324 extending and bending backward from the second grounding extension portion 323. In the left-right direction, the width of the second grounding extension portion 323 is equal to the width of the second extension portion 313. A second distance H2 exists between the second extension portion 313 and the second grounding extension portion 323, and the first distance H1 is smaller than the second distance H2.

[0038] like Figure 2 and Figure 3 As shown, the shielding member 4 includes a shielding main section 41 and an extension section 42 extending obliquely rearward from the shielding main section 41. In the vertical direction, a portion of the shielding main section 41 is located between the first contact portion 212 and the second contact portion 312, and another portion is located between the first main section 211 and the second main section 311. In a direction perpendicular to the extension direction of the extension section 42, the extension section 42 is located between the first extension portion 213 and the second extension portion 313. The extension section 42 has an end surface 421 facing away from the shielding main section 41.

[0039] like Figure 3As shown, in this embodiment, the first conductive portion 214 and the second conductive portion 314 are both elastic contact portions, and elastically abut the first element 200 downward and are electrically conductive with the first element 200. The first conductive portion 214 includes a first contact surface 2141 that contacts the first element 200, and the second conductive portion 314 includes a second contact surface 3141 that contacts the first element 200. The first contact surface 2141 and the second contact surface 3141 are located on the same plane. In other words, in this embodiment, the first contact surface 2141 and the second contact surface 3141 are aligned in the front-to-back direction. Of course, in other embodiments, the first contact surface 2141 and the second contact surface 3141 may also be arranged at the same height when viewed in the left-right direction.

[0040] like Figure 4 and Figure 6 As shown, in this embodiment, the first contact portion 212, the first grounding contact portion 222, and the second contact portion 312, the second grounding contact portion 322 are correspondingly arranged in different rows, that is, the first contact portion 212, the first grounding contact portion 222 are arranged in one row, and the second contact portion 312, the second grounding contact portion 322 are arranged in another row; the first conductive portion 214, the first grounding conductive portion 224, the second conductive portion 314, the second grounding conductive portion 324 are also correspondingly arranged in different rows, that is, the first conductive portion 214, the first grounding conductive portion 224 are arranged in one row, and the second conductive portion 314, the second grounding conductive portion 324 are arranged in another row. The conductive portion 314 and the second grounding conductive portion 324 are arranged in another row. Of course, in other embodiments, the first contact portion 212, the first grounding contact portion 222 and the second contact portion 312, the second grounding contact portion 322 are arranged in different rows, but the first conductive portion 214, the first grounding conductive portion 224, the second conductive portion 314, and the second grounding conductive portion 324 can be arranged in one row. That is, in other embodiments, the first conductive portion 214, the first grounding conductive portion 224, the second conductive portion 314, and the second grounding conductive portion 324 are aligned in the left-right direction.

[0041] like Figures 7 to 9 As shown, the first conductive portion 214 and the first grounding conductive portion 224 are respectively located behind the second conductive portion 314 and the second grounding conductive portion 324. The length of the first extension portion 213 in its extension direction is greater than the length of the second extension portion 313 in its extension direction. In the left-right direction, the width of the first extension portion 213 is greater than the width of the second extension portion 313, and the width of the first grounding extension portion 223 is greater than the width of the second grounding extension portion 323.

[0042] like Figure 7As shown, the portion of the first extension portion 213 that extends beyond the end surface 421 in the direction close to the first connecting portion 214 is defined as the first section P1, and the portion of the second extension portion 313 that extends beyond the end surface 421 in the direction close to the second connecting portion 314 is defined as the second section P2. The length of the first section P1 is greater than the length of the second section P2. In other embodiments, the second extension portion 313 may not extend beyond the end surface 421 in the direction close to the second connecting portion 314. In other words, the second extension portion 313 is not provided with the second section P2. For details, please refer to Figure 8 The extension section 42 extends beyond the second extension portion 313 in a direction away from the shielding main section 41. The portion of the extension section 42 extending beyond the second extension portion 313 in a direction away from the shielding main section 41 is defined as the third section P3. The second conductive portion 314 has an end portion 3142, and the end portion 3142 is located on a side of the second conductive portion 314 away from the second extension portion 313. The third section P3 does not extend beyond the end portion 3142 in a direction away from the shielding main section 41. Please refer to Figure 9 , viewed in a direction perpendicular to the extending direction of the second extending portion 313 , the projection of the extending section 42 and the projection of the second guiding portion 314 are completely staggered.

[0043] like Figures 2 to 5 As shown, the electrical connector 100 also includes an insulating plug 5, which includes a plurality of partition bars 51, a limiting surface 53 and a base plate 54. The partition bars 51 are used to separate the first row of terminals 2 or the second row of terminals 3. A horizontal partition bar 52 is provided between each two adjacent partition bars 51, and the horizontal partition bar 52 connects the two adjacent partition bars 51. The horizontal partition bar 52 is located below the first extension portion 213 and behind the second conductive portion 314 and / or the second grounding conductive portion 324, and is spaced apart from the second conductive portion 314 and / or the second grounding conductive portion 324 in front and back. Along the up and down direction, the width of the horizontal partition bar 52 gradually narrows from front to back.

[0044] The plurality of partition bars 51 include a first partition bar 511, a second partition bar 512, and a third partition bar 513. The first partition bar 511 is used to separate two adjacent first signal terminals 21a, the second partition bar 512 is used to separate two adjacent second signal terminals 31a, and the third partition bar 513 is used to separate two adjacent left and right terminals of other functions, or between the first signal terminal 21a and terminals of other functions, or between the second signal terminal 31a and terminals of other functions. The terminals of other functions may be power supply, detection, grounding terminals, etc. In this embodiment, the first differential signal pair 21 and the second differential signal pair 31 are arranged correspondingly in front and back, and the first partition bar 511 is connected to the second partition bar 512 in an integrated manner forward. In the up and down direction, the first partition bar 511 is higher than the second partition bar 512.

[0045] The limiting surface 53 is arranged forward and is located on the side of the extension section 42 facing away from the shielding main section 41, and is spaced in front of and behind the end surface 421. The base plate 54 is located behind the first conductive portion 214 and is spaced in front of and behind the first conductive portion 214. Along the front-to-back direction, a third distance H3 exists between the limiting surface 53 and the end surface 421, and a fourth distance H4 exists between the first conductive portion 214 and the base plate 54, wherein the third distance H3 is smaller than the fourth distance H4.

[0046] like Figures 3 to 5 As shown, along the front-to-back direction, the first partition column 511 is provided with a clearance groove 5111, and the facing portions of the two first extensions 213 are located in the same clearance groove 5111, so as to avoid damage to the first signal terminal 21a caused by interference between the first extension 213 and the partition column 51. Of course, in order to achieve this purpose, in other embodiments, the clearance groove 5111 may not be provided along the left-right direction, such as Figure 5 As shown in the first partition column 511 on the left, the width of the first partition column 511 is set to be smaller than the width of the third partition column 513, so that the gap between two adjacent first extensions 213 is larger than the width of the first partition column 511.

[0047] like Figure 5 As shown, in this embodiment, one of the first dividing columns 511 is provided with a giveway slot 5111, and the other first dividing column 511 is set to have a width smaller than the width of the third dividing column 513; in other embodiments, each first dividing column 511 can be provided with a giveway slot 5111, or the width of each first dividing column 511 can be set to be smaller than the width of any third dividing column 513.

[0048] In summary, the present invention has the following beneficial effects:

[0049] 1. The length of the first extension portion 213 in its extension direction is greater than the length of the second extension portion 313 in its extension direction. Therefore, the inductance at the first extension portion 213 is greater than the inductance at the second extension portion 313. Furthermore, the portion of the first extension portion 213 extending beyond the end surface 421 in the direction close to the first conductive portion 214 is defined as the first section P1, and the portion of the second extension portion 313 extending beyond the end surface 421 in the direction close to the second conductive portion 314 is defined as the second section P2, or does not extend beyond the end surface 421. In this application, the length of the first section P1 is set to be greater than the length of the second section P2. In other words, the capacitive coupling between the first extension portion 213 and the extension section 42 is less than the capacitive coupling between the second extension portion 313 and the extension section 42, so that the first signal terminal 21 The impedance of a at the first extension portion 213 is greater than the impedance of the second signal terminal 31a at the second extension portion 313. The present application also sets the width of the first extension portion 213 to be greater than the width of the second extension portion 313, so that the impedance at the first extension portion 213 matches the impedance at the second extension portion 313. In other words, the width of the first extension portion 213 is greater than the width of the second extension portion 313, so that the inductance of the first extension portion 213 is reduced, thereby reducing the impedance at the first extension portion 213, and ultimately optimizing the time lag between the first differential signal pair 21 and the second differential signal pair 31 caused by the impedance difference between the first extension portion 213 and the second extension portion 313, which is beneficial to signal transmission and improves the signal integrity performance of the electrical connector 100.

[0050] 2. The portion of the extension section 42 that extends beyond the second extension portion 313 in a direction away from the shielding main section 41 is defined as the third section P3. The third section P3 does not extend beyond the end portion 3142 of the second conductive portion 314. In other words, there are two scenarios. In the first scenario, the third section P3 completely shields the second conductive portion 314, reducing crosstalk between the second conductive portion 314 and the first signal terminal 21a. In the second scenario, the third section P3 partially shields the second conductive portion 314. While ensuring a certain shielding effect, the provision of the extension section 42 does not significantly affect the impedance of the second conductive portion 314, thereby facilitating signal transmission.

[0051] 3. Viewed in a direction perpendicular to the extension direction of the second extension portion 313, the projection of the extension section 42 and the projection of the second conductive portion 314 are completely offset. This ensures that the extension section 42 substantially does not affect the impedance of the second conductive portion 314, thereby preventing a significant impedance difference between the first conductive portion 214 and the second conductive portion 314, thereby facilitating signal transmission.

[0052] 4. In the present application, the first contact surface 2141 where the first conductive portion 214 contacts the first component 200 and the second contact surface 3141 where the second conductive portion 314 contacts the first component 200 are located in the same plane, and the first angle R1 between the first main portion 211 and the first extension portion 213 is smaller than the second angle R2 between the second main portion 311 and the second extension portion 313. This increases the length of the second extension portion 313, shortens the length difference between the first extension portion 213 and the second extension portion 313, and reduces the time lag between the first signal terminal 21a and the second signal terminal 31a, thereby facilitating signal transmission.

[0053] 5. The first distance H1 between the first extension portion 213 and the first ground extension portion 223 is smaller than the second extension portion 313.

[0054] The second spacing H2 between the first ground terminal 22 and the second ground extension portion 323, that is, the capacitance between the first ground terminal 22 and the first signal terminal 21a is greater than the capacitance between the second ground terminal 32 and the second signal terminal 31a, thereby reducing the impedance of the first signal terminal 21a, and further reducing the signal reflection and crosstalk caused by the impedance difference of the first signal terminal 21a at the first extension portion 213, thereby improving the signal integrity of the electrical connector 100.

[0055] 6. Along the arrangement direction of the first row of terminals 2, the width of the first extension 213 is greater than the width of the first ground extension 223. Along the arrangement direction of the second row of terminals 3, the width of the second extension 313 is equal to the width of the second ground extension 323. The width of the first ground extension 223 along the arrangement direction of the first row of terminals 2 is greater than the width of the second ground extension 323 along the arrangement direction of the second row of terminals 3. This arrangement can optimize the signal return path at the first extension 213 and the second extension 313, which is beneficial to signal transmission.

[0056] 7. The present application sets a first partition bar 511 between two adjacent first signal terminals 21a, and sets a second partition bar 512 between two adjacent second signal terminals 31a, and the first partition bar 511 is higher than the second partition bar 512 along the arrangement direction perpendicular to the arrangement direction of the first row of terminals 2 or the arrangement direction of the second row of terminals 3, so that the dielectric constant around the first row of terminals 2 is greater than the dielectric constant around the second row of terminals 3, further adjusting the impedance matching of the first row of terminals 2 and the second row of terminals 3 at the first extension portion 213 and the second extension portion 313.

[0057] 8. The first signal terminal 21a is located between two adjacent partitions 51 of the insulating plug 5. Along the arrangement direction of the first row of terminals 2, a partition 51 is located between two first signal terminals 21a in the first differential signal pair 21.

[0058] A clearance groove 5111 is provided, and the facing portions of the two first extension portions 213 are located in the same clearance groove 5111.

[0059] This prevents the first signal terminal 21 a from being damaged due to interference between the first extension portion 213 and the partition bar 51 .

[0060] 9. The insulating plug 5 includes a plurality of partition bars 51 , wherein the partition bars 51 include a first partition bar 511 and a third partition bar 513 .

[0061] The first partition bar 511 is located between the two first signal terminals 21a in the first differential signal pair 21, wherein the width of the first partition bar 511 is smaller than the width of the third partition bar 513 along the arrangement direction of the first row of terminals 2, and

[0062] The gap between the two first extensions 213 is larger than the width of the first partition bar 511 to prevent the first extensions 213 from

[0063] The first signal terminals 21 a are damaged due to interference with the first partition bar 511 .

[0064] 10. Along the arrangement direction perpendicular to the first row of terminals 2, a horizontal partition 52 is provided between two adjacent partitions 51, and the horizontal partition 52 connects the two partitions 51, thereby strengthening the strength of the partitions 51 and preventing breakage when assembling the insulating plug 5; further, along the arrangement direction perpendicular to the first row of terminals 2, the present application also arranges the horizontal partition 52 to gradually narrow from the first extension portion 213 to the first conductive portion 214, that is, the signal transmission path from the first extension portion 213 to the first conductive portion 214, since the change of the medium (horizontal partition 52) is gradual, the signal here can hardly feel the impedance difference caused by the change of the medium, which is more conducive to signal transmission.

[0065] 11. A third distance H3 between the limiting surface 53 of the insulating plug 5 and the end surface 421 is smaller than a fourth distance H4 between the first conductive portion 214 and the base plate 54 of the insulating plug 5. This allows the extension 42 of the shielding member 4 to first engage the limiting surface 53 for position limiting during assembly of the insulating plug 5. This means that the end surface 421 will first abut the limiting surface 53, thereby limiting further displacement of the insulating plug 5. Consequently, the first conductive portion 214 will not abut the base plate 54, thereby preventing damage to the first signal terminal 21a caused by collision between the base plate 54 and the first conductive portion 214.

[0066] The above detailed description is only an illustration of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this invention are included in the patent scope of this invention.
