[0029]

[0030] [Specific implementation method]

[0031] In order to facilitate a better understanding of the purpose, structure, features and functions of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0032] In order to more conveniently understand the technical solution of the present invention, the X-axis in the three-dimensional coordinate axes in the drawings of the specification is defined as the left-right direction, the Y-axis is defined as the front-back direction, and the Z-axis is defined as the up-down direction, wherein the X-axis, Y-axis and Z-axis are perpendicular to each other.

[0033] like Figure 1 The utility model electrical connector 100 is used to electrically connect a docking element (not shown) and a substrate (not shown), and includes a base 10, two insulators 12, two rows of terminals 20, and a plurality of grounding components 50. The two insulators 12 are respectively accommodated in the base 10, and each row of terminals 20 is respectively injection molded with an insulator 12. Of course, in other embodiments, each row of terminals 20 can be assembled with the insulator 12. The base 10 is provided with a slot 11, and the slot 11 extends along the front-to-back direction Y. The electrical connector 100 is plugged into the docking element (not shown) through the slot 11 to achieve electrical conduction.

[0034] like Figure 1 Each row of terminals 20 includes a plurality of signal terminals 30 and ground terminals 40, which are arranged along the left-right direction X and accommodated in the insulator 12, wherein the signal terminal 30 is located between two ground terminals 40. In this embodiment, two signal terminals 30 are included between the two ground terminals 40, and in other embodiments, only one signal terminal 30 may be provided between the two ground terminals 40.

[0035] like Figure 1 , Figure 2 and Figure 4 Each signal terminal 30 includes a base 31, a signal arm 32 extending forward from the base 31, and a signal soldering portion 33 extending backward from the base 31. The signal arm 32 is provided with a signal contact portion 321 exposed in the slot 11 in the front-to-back direction Y, and the base 31 is located between the signal contact portion 321 and the signal soldering portion 33 along the front-to-back direction Y. In this embodiment, the signal contact portion 321 and the signal soldering portion 33 are exposed to the air. Along the left-right direction X, the width of the base 31 is smaller than the maximum width of the signal arm 32, and the width of the base 31 is smaller than the maximum width of the signal soldering portion 33.

[0036] Each grounding terminal 40 includes a main body 41, a first deflection portion 43 extending forward from the main body 41 and a grounding arm 42, a second deflection portion 44 extending backward from the main body 41 and a grounding welding portion 45. The grounding arm 42 is provided with a grounding contact portion 421 exposed in the slot 11 in the front-to-back direction Y, the first deflection portion 43 is connected forwardly to the grounding contact portion 421, and the second deflection portion 44 is connected backwardly to the grounding welding portion 45. The main body 41, the first deflection portion 43 and the second deflection portion 44 are fixed to the insulator 12, and the grounding arm 42 is not fixed to the insulator 12 and is movable. In this embodiment, the grounding arm 42 abuts against the docking element (not shown), and the grounding arm 42 can move in the up-down direction Z. Since the main body 41, the first deflection portion 43, and the second deflection portion 44 are fixed to the insulator 12, the fulcrum for the grounding arm 42 to move in the up-down direction Z is fixed, and the part of the grounding terminal 40 fixed to the insulator 12 (the main body 41, the first deflection portion 43, and the second deflection portion 44) forms the fulcrum.

[0037] like Figure 3 and Figure 7 In the vertical direction Z, the top surface of the grounding arm 42 includes a first cutting surface S1, a second cutting surface S2 and a third cutting surface S3. The second cutting surface S2 is connected to the first cutting surface S1 backward and connected to the third cutting surface S3 forward. In this embodiment, the first cutting surface S1 and the third cutting surface S3 are not coplanar. If the second cutting surface S2 is not provided, the first cutting surface S1 and the third cutting surface S3 are directly connected to form a tip, which will cause the grounding terminal 40 to be unbalanced and break. In order to increase the service life of the grounding terminal 40, the second cutting surface S2 smoothly connects the first cutting surface S1 and the third cutting surface S3 to reduce stress concentration. Along the vertical direction Z, the distance between the first cutting surface S1 and the bottom surface of the grounding arm 42 is a first height H1, and the distance between the third cutting surface S3 and the bottom surface of the grounding arm 42 is a second height H2. The first height H1 is greater than the second height H2 and greater than the height of the first deflection portion 43. In the front-to-back direction Y, the first cutting surface S1 is closer to the fulcrum than the third cutting surface S3, and the first height H1 is greater than the second height H2, so that the unit force area at the first cutting surface S1 is larger, and the stress concentration at the first cutting surface S1 can be reduced. In the up-down direction Z, the first cutting surface S1 is higher than the top surface of the first deflection portion 43, so that the ground terminal 40 can shield the noise scattered by the signal terminal 30 in a larger range in the up-down direction Z to reduce crosstalk.

[0038] In this embodiment, the grounding soldering portion 45 is in contact with a substrate (not shown). Figures 1 to 7, along the left-right direction X, the deflection direction of the first deflection portion 43 relative to the main body 41 is the same as the deflection direction of the second deflection portion 44 relative to the main body 41; along the front-back direction Y, the projection of the grounding contact portion 421 is staggered with the projection of the main body 41, and the projection of the grounding welding portion 45 is staggered with the projection of the main body 41, and the projection of the grounding contact portion 421 overlaps with the projection of the grounding welding portion 45. In this embodiment, the first deflection portion 43 deflects to the left relative to the main body 41, and the second deflection portion 44 deflects to the left relative to the main body 41. Along the up-down direction Z, the height of the first deflection portion 43 is less than the height of the main body 41, and the height of the second deflection portion 44 is less than the height of the main body 41. The first deflection portion 43 and the second deflection portion 44 are both deflected at a certain angle relative to the main body 41, and the height of the first deflection portion 43 and the second deflection portion 44 are both less than the height of the main body 41, which can reduce the stress concentration at the positions of the first deflection portion 43 and the second deflection portion 44, making it easy to process and not easy to damage the ground terminal 40.

[0039] like Figures 1 to 3 , in the same row of terminals 20, along the left-right direction X, the signal contact portion 321 and the ground contact portion 421 are arranged one-to-one, the signal welding portion 33 and the ground welding portion 45 are arranged one-to-one, the base portion 31 and the main body portion 41 are arranged one-to-one, and the projection of the signal terminal 30 is located within the projection of the ground terminal 40. In this embodiment, the ground terminal 40 is manufactured by blanking, and the ground terminal 40 is in a plate shape. Each ground terminal 40 has two plate surfaces, and the two plate surfaces are arranged opposite to each other along the left-right direction X; and the signal terminal 30 is placed horizontally, so that the ground terminal 40 can increase the shielding range of the signal terminal 30 in the up-down direction Z to reduce crosstalk.

[0040] like Figure 1 , Figures 4 to 5 , multiple grounding components 50 are connected to each other along the left-right direction X and accommodated in the insulator 12, and each grounding component 50 includes two adjacent grounding terminals 40 and a bridge 60. The bridge 60 includes a bridge portion 61 and a bent portion 62 integrally extending from one end of the bridge portion 61 along the up-down direction Z. Multiple grounding terminals 40 are connected to each other along the left-right direction X through the bridge 60 and accommodated in the insulator 12.

[0041] Two adjacent grounding components 50 along the left-right direction X share one grounding terminal 40. It should be noted that, in this embodiment, along the left-right direction, the same grounding component 50 includes a grounding terminal 40 located on the left side (hereinafter referred to as the left terminal) and a grounding terminal 40 located on the right side (hereinafter referred to as the right terminal), the left terminal is the grounding terminal 40 located on the right side of an adjacent grounding component 50, and the right terminal is the grounding terminal 40 located on the left side of another adjacent grounding component 50.

[0042] like Figures 5 to 7In the same grounding assembly 50, along the left-right direction X, the bridge 60 is located between the two main bodies 41, and the bridge 61, the bent portion 62 and the main body 41 of the left terminal enclose a receiving space W1. Two bases 31 are arranged in the receiving space W1, one base 31 is close to the left terminal, and the other base 31 is close to the bent portion 62. Because the signal contact portion 321 and the signal welding portion 33 are exposed to the air, the impedance at the positions of both is large, and the base 31 is contained in the insulator 12 and is located in the receiving space W1 from the up and down direction Z. Because the dielectric constant of the insulator 12 is larger than that of air, the capacitance is increased, thereby reducing the impedance. In order to achieve impedance matching, the width of the base 31 is reduced relative to the width of the signal arm 32, and the width of the base 31 is reduced relative to the width of the signal welding portion 33, so as to increase the impedance and achieve impedance matching. The main body 41 of the left terminal is connected to the other end of the bridge 61 upward, and the main body 41 of the right terminal is connected to the bent portion 62 downward. In order to facilitate processing and manufacturing and improve assembly efficiency, the grounding terminal 40 and the bridge 60 are formed on the same metal plate, so that multiple grounding terminals 40 are connected by the bridge 60 in the left-right direction X, and two grounding terminals 40 and one bridge 60 form a grounding assembly 50. After the bridge 60 is bent, the bridge portion 61 is not in the same plane as the main body 41 and the bent portion 62, so that the grounding assembly 50 can shield the signal terminal 30 in the left-right direction X and on either side of the up-down direction Z, so as to improve the anti-crosstalk capability of the electrical connector 100. Because the grounding terminal 40 and the bridge 60 are integrated, when installed together with the signal terminal 30, the grounding assembly 50 only needs to be aligned once to install it, reducing the processing steps.

[0043] like Figure 1 and Figure 4, in the same grounding assembly 50, along the left-right direction X, the grounding contact portion 421 and the signal contact portion 321 are separated by a first distance L1, the base portion 31 close to the left terminal and the main body portion 41 of the left terminal are separated by a second distance L2, and the grounding welding portion 45 and the signal welding portion 33 are separated by a third distance L3; the first distance L1 is equal to the third distance L3, and the first distance L1 is greater than the second distance L2. The terminals are prone to crosstalk at the positions of the signal welding portion 33 and the grounding welding portion 45, but the specification requires that the distance between the grounding welding portion 45 and the signal welding portion 33 be equal to the distance between the grounding contact portion 421 and the signal contact portion 321. The first deflection portion 43 deflects to the left relative to the main body portion 41, and the second deflection portion 44 deflects to the left relative to the main body portion 41 to balance the spacing between the signal contact portion 321 and the grounding contact portion 421 and the spacing between the signal welding portion 33 and the grounding welding portion 45, ensuring that the first distance L1 is equal to the third distance L3 to meet the association specification. In this embodiment, in the same grounding component 50, the distance between the base 31 close to the left terminal and the main body 41 of the left terminal is shortened. The main body 41 is made of metal. The main body 41 is close to the base 31, so that the mutual capacitance and inductance between the main body 41 and the base 31 are reduced, thereby reducing crosstalk.

[0044] like Figure 1 and Figure 5 , in the same grounding component 50, along the left-right direction X, the base 31 close to the right terminal and the main body 41 of the right terminal are separated by a fourth distance L4, and the base 31 close to the right terminal and the bending portion 62 are separated by a fifth distance L5; the fourth distance L4 is greater than the first distance L1, and the fifth distance L5 is equal to the second distance L2. The fourth distance L4 is greater than the first distance L1, so that the bending portion 62 has sufficient space in the left-right direction X. Although the fourth distance L4 is greater than the first distance L1, the bending portion 62 in the left-right direction X plays the same shielding role as the main body 41 on the left, shortening the distance between the base 31 and the bending portion 62 so that the fifth distance L5 is equal to the second distance L2. The bending portion 62 and the main body 41 are both made of metal. The bending portion 62 is close to the base 31, so that the mutual capacitance and inductance between the main body 41 and the base 31 are reduced, thereby reducing crosstalk.

[0045] like Figure 4 and Figure 5, viewed from the front-to-back direction Y, the two signal terminals 30 include a bent portion 62 and a main body 41, and the spacing between the bent portion 62 and the adjacent signal terminal 30 is equal to the spacing between the main body 41 and the adjacent signal terminal 30, so that the bent portion 62 and the main body 41 can respectively shield the two signal terminals 30, i.e., the two bases 31, and the distance between each signal terminal 30 and the shielding structure (the bent portion 62 and the main body 41) in the left-right direction X is the same, and the shielding effects of the bent portion 62 and the main body 41 on the base 31 are almost the same to reduce crosstalk. Viewed from the front-to-back direction Y, the bent portion 62 between the two signal terminals 30 is adjacent to the main body 41, and there is a gap W2 between the bent portion 62 and the main body 41. Although the gap W2 is formed when bending, the existence of the gap W2 can increase the distance between the main body 41 and the bending portion 62, avoiding the two shielding structures (main body 41, bending portion 62) being too close to each other and causing impedance mismatch, while ensuring that the spacing between the main body 41 and the adjacent signal terminal 30 is equal to the spacing between the bending portion 62 and the adjacent signal terminal 30, which is conducive to reducing crosstalk and ensuring signal integrity. Along the front-to-back direction Y, the grounding contact portion 421 is located in the middle of the gap W2 and the grounding welding portion 45 is located in the middle of the gap W2; along the up-down direction Z, the distance that the first deflection portion 43 deflects relative to the main body 41 is equal to the distance that the second deflection portion 44 deflects relative to the main body 41, and the distance is equal to half the width of the gap W2.

[0046] In summary, the electrical connector 100 of the present invention has the following effects:

[0047] (1) In order to facilitate processing and manufacturing and improve assembly efficiency, the grounding terminal 40 and the bridge member 60 are formed on the same metal plate, so that multiple grounding terminals 40 are connected in the left-right direction X through the bridge member 60, and two grounding terminals 40 and one bridge member 60 form a grounding assembly 50. After the bridge member 60 is bent, the bridge portion 61 is not in the same plane as the main body portion 41 and the bent portion 62, so that the grounding assembly 50 can shield the signal terminal 30 in the left-right direction X and on either side of the up-down direction Z, so as to improve the anti-crosstalk capability of the electrical connector 100. Because the grounding terminal 40 and the bridge member 60 are integrated, when installed together with the signal terminal 30, the grounding assembly 50 only needs to be aligned once to install it, reducing the processing steps.

[0048] (2) Along the left-right direction X, the deflection direction of the first deflection portion 43 relative to the main body 41 is the same as the deflection direction of the second deflection portion 44 relative to the main body 41. The first deflection portion 43 deflects to the left relative to the main body 41, and the second deflection portion 44 deflects to the left relative to the main body 41 to balance the spacing between the signal contact portion 321 and the ground contact portion 421 and the spacing between the signal welding portion 33 and the ground welding portion 45, ensuring that the first distance L1 is equal to the third distance L3 to meet the association specification; Along the up-down direction Z, the height of the first deflection portion 43 is less than the height of the main body 41, and the height of the second deflection portion 44 is less than the height of the main body 41. The first deflection portion 43 and the second deflection portion 44 are both deflected at a certain angle relative to the main body 41, and the height of the first deflection portion 43 and the second deflection portion 44 are both less than the height of the main body 41, which can reduce the stress concentration at the positions of the first deflection portion 43 and the second deflection portion 44, facilitate processing and not easily damage the ground terminal 40.

[0049] (3) The signal contact portion 321 and the signal welding portion 33 are exposed to the air, and the impedance at both locations is large. The base 31 is accommodated in the insulator 12 and is located in the accommodation space W1 from the vertical direction Z. Because the dielectric constant of the insulator 12 is larger than that of air, the capacitance is increased, thereby reducing the impedance. In order to achieve impedance matching, the width of the base 31 is reduced relative to the width of the signal arm 32, and the width of the base 31 is reduced relative to the width of the signal welding portion 33, thereby increasing the impedance and achieving impedance matching.

[0050] (4) In the same grounding component 50, along the left-right direction X, the grounding contact portion 421 and the signal contact portion 321 are separated by a first distance L1, and the base portion 31 and the main body portion 41 located on the left are separated by a second distance L2. The first distance L1 is greater than the second distance L2, thereby shortening the distance between the base portion 31 and the main body portion 41 located on the left. The main body portion 41 is made of metal. The main body portion 41 is close to the base portion 31, so that the mutual capacitance and inductance between the main body portion 41 and the base portion 31 are reduced, thereby reducing crosstalk.

[0051] (5) When viewed from the front-to-back direction Y, the bent portion 62 between the two signal terminals 30 is adjacent to the main body 41, and there is a gap W2 between the bent portion 62 and the main body 41. The gap W2 is formed during bending, but the existence of the gap W2 can increase the distance between the main body 41 and the bent portion 62, thereby preventing the two shielding structures from being too close to each other and causing impedance mismatch. At the same time, the spacing between the main body 41 and the adjacent signal terminal 30 is equal to the spacing between the bent portion 62 and the adjacent signal terminal 30, thereby reducing crosstalk and ensuring signal integrity.

[0052] 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.
