Description

[Technical field]

[0001] The utility model relates to an electric connector, in particular to an electric connector for improving high frequency. [Background technology]

[0002] The Chinese patent application number CN202111108073.9 discloses an electrical connector, which includes an insulating shell 1, and a grounding terminal 31 and a signal component 32 installed on the insulating shell 1. The grounding terminal 31 includes a sheet-shaped segment 311, a protrusion 314, and an elastic arm segment 312 and a welding segment 313 extending from the sheet-shaped segment 311. The protrusion 314 extends from the sheet-shaped segment 311 and is adjacent to the elastic arm segment 312. A groove G is formed between the protrusion 314 and the elastic arm segment 312 and is recessed along the height direction D3 toward the mounting surface 12.

[0003] The above structure has the following problems:

[0004] Since the groove G is a gap formed by removing part of the metal material from the metal plate, the signals emitted by the two signal components at both ends of the ground terminal are easily leaked from the groove G of the ground terminal, causing mutual interference.

[0005] Therefore, it is necessary to design a new electrical connector to overcome the above problems. [Contents of the utility model]

The distance between the two opposite signal board edges 31 is defined as the thickness of the signal terminal 3, and the distance between the two opposite signal cutting edges 32 is defined as the width of the signal terminal 3. In other embodiments, the signal terminal 3 is formed by metal bending, and the signal terminal 3 includes two opposite signal board edges 31 and two opposite signal cutting edges 32, and the signal board edges 31 and the signal cutting edges 32 are connected.

The signal elastic portion 35 also includes a narrow portion 354 extending upward from the signal main body portion 33 and a wide portion 353 extending upward from the narrow portion 354. The width of the narrow portion 354 is smaller than the width of the wide portion 353. The signal elastic portion 35 reduces the normal force by arranging the narrow portion 354 near one end of the signal main body portion 33.

[0042] like Figures 3 to 5 As shown, the ground terminal 4 is in the shape of a plate, and the ground terminal 4 includes two opposite ground plate edges 41 and two opposite ground cutting edges 42, and the ground plate edges 41 and the ground cutting edges 42 are connected. The distance between the two opposite ground plate edges 41 is defined as the thickness of the ground terminal 4, and the distance between the two opposite ground cutting edges 42 is defined as the width of the ground terminal 4. The ground plate edge 41 of the ground terminal 4 is directly opposite to the signal plate edge 31 of the signal terminal 3 in the left-right direction. When viewed from the left-right direction, the projection of the entire signal terminal 3 in the front-back direction is located within the projection of the entire ground terminal 4. Specifically, in this embodiment, not only when viewed from the left-right direction, the entire ground terminal 4 can shield the entire signal terminal 3 in the front-back direction, but also the distance between the two ground cutting edges 42 is greater than the distance between the two signal cutting edges 32, and does not include the case where the distance between the two ground cutting edges 42 is equal to the distance between the two signal cutting edges 32. In other embodiments, the ground plate edge 41 of the ground terminal 4 is directly opposite to the signal cutting edge 32 of the signal terminal 3 in the left-right direction. Not only when observed from the left and right directions, the entire ground terminal 4 can cover the entire signal terminal 3 along the front and back directions, but also the distance between the two ground cutting edges 42 must be greater than the distance between the two signal board edges 31, and does not include the situation where the distance between the two ground cutting edges 42 is equal to the distance between the two signal board edges 31.

[0043] like Figures 3 to 5As shown, the grounding terminal 4 includes a grounding body portion 43, a grounding contact portion 44, a grounding elastic portion 45 connected between the grounding body portion 43 and the grounding contact portion 44, and a grounding conductive portion 46 connected to one end of the grounding body portion 43 away from the grounding elastic portion 45. The plurality of grounding body portions 43 are fixed to the grounding fixing slot 141 along the front-to-back direction, the grounding contact portion 44 protrudes from the receiving slot 14 to the card insertion slot 13 for abutting against the first electronic component 200, and the grounding conductive portion 46 is used to abut against the second electronic component 300.

[0044] like Figure 3 and Figure 6 As shown, the grounding body portion 43 includes a grounding extension portion 431 extending downward from the grounding elastic portion 45 and a grounding fixing portion 432 extending forward from the grounding extension portion 431. A plurality of grounding fixing portions 432 are engaged with the grounding fixing groove 141 and abut against the base 21 of the grounding sheet 2 downward. A plurality of grounding extension portions 431 are located outside the grounding fixing groove 141, and a plurality of clamping portions 23 clamp the plurality of grounding extension portions 431. The grounding fixing groove 141 includes an upper wall 1411 located above the grounding fixing portion 432.

[0045] like Figures 3 to 5 As shown, the grounding elastic portion 45 of the grounding terminal 4 of the first terminal row includes a first section 451 extending upward from the grounding main body portion 43, a second section 452 extending forward from the first section 451 by bending, and a tearing portion 453 located in the first section 451. The second section 452 is connected to the grounding contact portion 44. The tearing portion 453 is located at one end of the grounding elastic portion 45 close to the grounding extension portion 431 and is kept at a distance from the upper wall 1411. The tearing portion 453 of the grounding terminal 4 in the left-right direction is at least partially opposite to the narrow portion 354. The signal elastic portions 35 of the plurality of signal terminals 3 of the first terminal row do not have the tearing portion 453.

[0046] like Figure 3 to Figure 4 As shown, the grounding elastic part 45 of the first terminal row also includes a first grounding side edge 454 and a second grounding side edge 455 opposite to each other, wherein the first grounding side edge 454 and the second grounding side edge 455 are positions of the grounding elastic part 45 corresponding to the two opposite grounding cutting edges 42 of the grounding terminal 4. The tearing part 453 is torn from the first grounding side edge 454 to the second grounding side edge 455 respectively. When the first electronic component 200 abuts against the grounding contact part 44, the grounding contact part 44 is displaced in the direction from the first grounding side edge 454 to the second grounding side edge 455, that is, it is displaced upward and backward, and drives the tearing part 453 to stretch upward. Specifically, the tearing part 453 includes an upper inner wall surface 4531 and a lower inner wall surface 4532. When the first electronic component 200 abuts against the grounding contact part 44, the distance between one end of the upper inner wall surface 4531 close to the first grounding side edge 454 and one end of the lower inner wall surface 4532 close to the first grounding side edge 454 becomes larger.

[0047] like Figure 4 As shown, when observing along the arrangement direction of the plurality of signal terminals 3 and the plurality of ground terminals 4 (i.e., the left-right direction), the projection of the entire signal elastic portion 35 is located within the projection of the entire ground elastic portion 45. It should be noted that when observing along the left-right direction, the projection of the entire signal elastic portion 35 is located within the projection of the entire ground elastic portion 45.

[0048] like Figure 3 to Figure 4 As shown, in this embodiment, the tearing portion 453 includes a first tearing portion 4533 and a second tearing portion 4534 located below the first tearing portion 4533. The first tearing portion 4533 is closer to the grounding contact portion 44 than the second tearing portion 4534, and the second tearing portion 4534 is closer to the grounding body portion 43 than the first tearing portion 4533. The width D3 of the first tearing portion 4533 is greater than the width D4 of the second tearing portion 4534. The distance D5 between the first tearing portion 4533 and the second tearing portion 4534 is greater than the width D3 of the first tearing portion 4533 and greater than the width D4 of the second tearing portion 4534. One end of the upper inner wall of the first tear portion 4533 close to the second grounding side 455 is connected to one end of the lower inner wall of the first tear portion 4533 close to the second grounding side 455, which is defined as the bottom of the first tear portion 4533; one end of the upper inner wall of the second tear portion 4534 close to the second grounding side 455 is connected to one end of the lower inner wall of the second tear portion 4534 close to the second grounding side 455, which is defined as the bottom of the second tear portion 4534; the distance D8 from the bottom of the first tear portion 4533 to the second grounding side 455 is smaller than the distance D9 from the bottom of the second tear portion 4534 to the second contact side.

The third tear portion 4535 and the fourth tear portion 4536 are located between the second tear portion 4534 and the grounding body portion 43, and the third tear portion 4535 is closer to the grounding body portion 43 than the fourth tear portion 4536. The distance D5 between the first tear portion 4533 and the second tear portion 4534 is equal to the distance D6 between the third tear portion 4535 and the fourth tear portion 4536, and the distance D7 between the second tear portion 4534 and the third tear portion 4535 is greater than the distance D5 between the first tear portion 4533 and the second tear portion 4534. An end of the upper inner wall of the first tear portion 4533 close to the second ground contact side 455 is connected to an end of the lower inner wall of the first tear portion 4533 close to the second ground contact side 455, which is defined as the bottom of the first tear portion 4533; an end of the upper inner wall of the second tear portion 4534 close to the second ground contact side 455 is connected to an end of the lower inner wall of the second tear portion 4534 close to the second ground contact side 455, which is defined as the bottom of the second tear portion 4534; an end of the upper inner wall of the third tear portion 4535 close to the second ground contact side 455 is connected to an end of the lower inner wall of the third tear portion 4535 close to the second ground contact side 455, which is defined as the bottom of the third tear portion 4535; and a fourth tear portion One end of the upper inner wall of 4536 close to the second grounding side 455 is connected to one end of the lower inner wall of the fourth tear portion 4536 close to the second grounding side 455, which is defined as the bottom of the fourth tear portion 4536; the distance D8 from the bottom of the first tear portion 4533 to the second grounding side 455 is smaller than the distance D9 from the bottom of the second tear portion 4534 to the second contact side, the distance D9 from the bottom of the second tear portion 4534 to the second contact side is smaller than the distance D10 from the bottom of the third tear portion 4535 to the second contact side, and the distance D10 from the bottom of the third tear portion 4535 to the second contact side is smaller than the distance D11 from the bottom of the fourth tear portion 4536 to the second contact side.

[0050] In summary, the electrical connector 100100 of the utility model has the following beneficial effects:

[0051] 1. At least one grounding terminal 4 is located between two signal terminals 3, and the grounding terminal 4 can effectively shield the signal interference between the two signal terminals 3; in order to improve the shielding effect of the grounding terminal 4, the projection of the entire signal elastic part 35 can be arranged in the projection of the entire grounding elastic part 45 when viewed along the direction in which the plurality of signal terminals 3 and the plurality of grounding terminals 4 are arranged. However, this will cause the positive force of the grounding elastic part 45 to be too large, which is easy to wear the contact surface electroplating layer of the grounding contact part 44 and easy to fatigue, thereby affecting the electrical performance of the grounding terminal 4. In addition, by providing a tearing part 453 on the grounding elastic part 45, the positive force of the grounding elastic part 45 can be effectively reduced, solving the problem of the positive force of the grounding elastic part 45 being too large. Since the tearing part 453 is formed by directly tearing the grounding elastic part 45, compared with directly providing a notch on the grounding elastic part 45, it can reduce signal leakage and effectively shield the signal interference between the two signal terminals 3.

[0052] 2. The tearing portion 453 is arranged at the second section 452 close to the grounding contact portion 44. The width of the second section 452 corresponding to the tearing portion 453 is reduced, so part of the stress is concentrated in the second section 452. The second section 452 is prone to fatigue, which affects the contact between the grounding contact portion 44 and the first electronic component 200. Compared with the tearing portion 453 arranged at the second section 452 close to the grounding contact portion 44, the tearing portion 453 is arranged at the first section 451 far from the grounding contact portion 44, which not only ensures that the second section 452 is not prone to fatigue, but also helps to avoid the instability of the height difference of the grounding contact portion 44, and ensures good contact between the grounding contact portion 44 and the first electronic component 200; the distance from the grounding contact portion 44 to the first section 451 is greater than the distance from the grounding contact portion 44 to the second section 452. The tearing portion 453 is arranged at the first section 451 far from the grounding contact portion 44, and the force arm from the grounding contact portion 44 to the tearing portion 453 is lengthened, and the positive force reduction effect of the grounding elastic portion 45 is obvious.

[0053] 3. The signal terminal 3 is in the shape of a plate, which facilitates direct stamping of the ground terminal 4 and the signal terminal 3 on the same metal plate; the signal elastic portion 35 includes a narrow portion 354 extending upward from the signal main portion 33 and a wide portion 353 extending upward from the narrow portion 354, the width of the narrow portion 354 is smaller than the width of the wide portion 353, and the signal elastic portion 35 reduces the positive force by arranging the narrow portion 354 at one end close to the signal main portion 33. Each signal elastic portion 35 does not have a tearing portion 453, which can effectively avoid affecting the signal transmission of the signal terminal 3.

[0054] 4. Compared with setting a notch or a tear portion 453, setting a first tear portion 4533 and a second tear portion 4534 can disperse stress, reduce the yield, and prevent the grounding elastic portion 45 from being easily fatigued; the bottom of the first tear portion 4533 where the grounding elastic portion 45 is located is the first stress concentration position, and the bottom of the second tear portion 4534 where the grounding elastic portion 45 is located is the second stress concentration position. The distance D5 between the first tear portion 4533 and the second tear portion 4534 is greater than the width D3 of the first tear portion 4533 and greater than the width D4 of the second tear portion 4534, so as to avoid the distance between the first stress concentration and the second stress concentration being too small, and ensure that the stress at the first tear portion 4533 and the second tear portion 4534 where the grounding elastic portion 45 is located is relatively dispersed.

[0055] 5. Compared with setting a notch or a tear portion 453, setting a first tear portion 4533 and a second tear portion 4534 can not only effectively achieve the required reduction in the normal force value, but also disperse the stress, reduce the yield amount, and the grounding elastic portion 45 is not easy to fatigue. The width D3 of the first tear portion 4533 is greater than the width D4 of the second tear portion 4534, which is convenient for fine-tuning the size of the normal force.

[0056] 6. Since the first tearing portion 4533 is closer to the grounding contact portion 44 than the second tearing portion 4534, the distance D8 from the bottom of the first tearing portion 4533 to the second grounding side 455 is set to be smaller than the distance D9 from the bottom of the second tearing portion 4534 to the second contact side. According to the equal strength theory, the grounding elastic portion 45 can disperse stress, reduce the yield, and facilitate reliable contact of the terminal. Since the grounding body 43 is fixed to the insulating body 1, the second tearing portion 4534 is closer to the grounding body 43 than the first tearing portion 4533, so the stress of the second tearing portion 4534 is more concentrated than that of the first tearing portion 4533. The distance D8 from the bottom of the first tearing portion 4533 to the second grounding side 455 is set to be smaller than the distance D9 from the bottom of the second tearing portion 4534 to the second contact side. The strength of the grounding elastic portion 45 at the second tearing portion 4534 is greater than the strength of the grounding elastic portion 45 at the first tearing portion 4533, which can reduce the risk of broken needles.

[0057] 7. The tearing portion 453 also includes a third tearing portion 4535 and a fourth tearing portion 4536. The third tearing portion 4535 is closer to the grounding main portion 43 than the fourth tearing portion 4536. The distance from the bottom of the second tearing portion 4534 to the second grounding side 455 is smaller than the distance from the bottom of the third tearing portion 4535 to the second contact side. The distance from the bottom of the third tearing portion 4535 to the second grounding side 455 is smaller than the distance from the bottom of the fourth tearing portion 4536 to the second contact side. According to the equal strength theory, the stress is further dispersed, the yield strength is reduced, and the reliability of the terminal contact is beneficial.

[0058] 8. Apply a thrust to the grounding extension portion 431 so that the grounding fixing portion 432 is engaged with the grounding fixing groove 141. The tearing portion 453 is arranged at one end of the grounding elastic portion 45 close to the grounding extension portion 431 and is kept at a distance from the upper wall 1411. A sufficient safety distance is reserved to prevent the tearing portion 453 from interfering with the upper wall 1411, which can effectively avoid the pin breakage phenomenon when the grounding terminal 4 is assembled to the insulating body 1.

[0059] 9. The receiving groove 15 is connected to the multiple grounding fixing grooves 141, and the grounding plate 2 is received in the receiving groove 15. The multiple grounding main bodies 43 are fixed to the multiple grounding fixing grooves 141 and abut against the grounding plate 2 downward, so as to ensure that the grounding terminal 4 is fixed to the insulating body 1 while achieving the common grounding of the multiple grounding main bodies 43 and the grounding plate 2 with equal electric potential, which is beneficial to improving the shielding effect.

[0060] 10. The grounding plate 2 abuts against multiple grounding fixing parts 432 and multiple grounding extension parts 431 at the same time to achieve common grounding, which can ensure that the grounding plate 2, the grounding fixing part 432 and the grounding extension part 431 have equal electric potential, which is beneficial to improving the shielding effect, further reducing the electromagnetic signal interference emitted by the signal terminal 3, and ensuring the stability of the grounding shielding performance of the electrical connector 100.

[0061] The above detailed description is only an explanation of the preferred embodiment of the utility model, and does not limit the patent scope of the utility model. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
