[0040] like Figures 1 to 7As shown, the terminal 100 of the first embodiment of the present application is as follows: the first section 1 is provided with a first docking portion 11, a first main body portion 12, a contraction section 13 and a first welding portion 14 in sequence along the front-to-back direction, and the first docking portion 11 and part of the first main body portion 12 protrude out of the insulating module M, and the other part of the first main body portion 12, the contraction section 13 and the first welding portion 14 are fixed in the insulating module M.

[0042] The second section 2 includes a second butting portion 24 and a second welding portion 21. The second welding portion 21 is fixed to the insulation module M and is perpendicular to the first welding portion 14.

[0043] The second welding portion 21 has two second plate surfaces 211 arranged opposite to each other in the left-right direction, two second material thickness surfaces 212 arranged opposite to each other in the up-down direction, a first welding surface 213 and a second welding surface 214. The width direction of the first plate surface 141 and the width direction of the second plate surface 211 are perpendicular to each other. In other embodiments, the angle between the width direction of the first plate surface 141 and the width direction of the second plate surface 211 can be adjusted according to the actual needs of the user for the high-frequency performance of the terminal 100, such as 30°, 45°, 60°, etc. The first welding portion 14 and the second welding portion 21 partially overlap along the direction of the second plate surface 211 and are fixed by laser welding.

[0048] like Figure 12 to Figure 14 As shown, the terminal 100 of the third embodiment of the present application, in the third embodiment, the rest of the structure is the same as the first embodiment, the only difference is: the first section 1 is also provided with a fourth welding portion 15, the fourth welding portion 15 is formed by extending outward from one of the first material thickness surfaces 142 in the left-right direction. The fourth welding portion 15 also has a fourth welding surface 151 that is welded and fixed to the second section 2 in the left-right direction. In other embodiments, according to the actual needs of the user for the current carrying capacity and high-frequency performance of the terminal 100, the terminal 100 may also have the third welding portion 22 and the fourth welding portion 15 at the same time.

[0049] In summary, the terminal 100 of the present invention has the following beneficial effects:

[0050] 1. In the present application, the first welding portion 14 and the second welding portion 21 are arranged along the second plate surface.

[0051] 211, and the first welding portion 14 is partially overlapped and welded in place, and the width W4 of the first welding portion 14 along the left-right direction is the same as the width W5 of the second welding portion 21 along the left-right direction, that is, when viewed from the perspective of the second plate surface 211, the two first material thickness surfaces 142 are respectively flush with the two second plate surfaces 211, so that the current flows freely.

[0052] During the conduction from the second section 2 to the first section 1, based on the skin effect of the current, the current can be smoothly conducted along the second plate surface 211 to the first material thickness surface 142, so that the current conduction direction transitions smoothly; the situation that the torsion section is set to increase the crosstalk is avoided; and at the same time, during the welding

[0053] When welding, the welding jig can be vertically aligned with the first material thickness surface 142 and / or the second plate surface 211 for welding, which helps to accurately position the welding jig and facilitates observation of the welding condition, thereby improving the welding yield.

[0054] while the first welding surface 213 and the second welding surface 214 are respectively welded with the first welding portion 14 along the up and down and front and back directions, so that the first welding portion 14 and the second welding portion 21 are welded more firmly.

[0055] 2. The first docking portion 11 and part of the first main body 12 protrude from the insulating module M, and the contraction section 13 is fixed in the insulating module M. Since the dielectric constant of plastic is greater than that of air, according to the formula (C is the capacitance, ε is the dielectric constant of the transmission medium), due to the increase of the dielectric constant ε

[0056] The capacitance C increases, and the formula It can be seen that the impedance Z is reduced, so the impedance of the contraction section 13 fixed in the insulating module M is smaller than the impedance of the first docking portion 11 and part of the first main body 12 protruding out of the insulating module M, so that the impedance of the same terminal 100 is not matched. Therefore, by setting the width W3 of the contraction section 13 along the left-right direction to be smaller than the width of the first main body 12 along the left-right direction, the area S is reduced, the capacitance C is increased, and the impedance is increased, so that the impedance of the same terminal 100 is matched.

[0057] 3. By providing the buffer section 122 extending obliquely from the first main body 12 to the contraction section 13, and the buffer section 122 is fixed in the insulation module M, the area S is further reduced. According to the formula

[0058] Thus increasing the capacitance C, according to the formula It can be seen that further reducing the impedance Z further reduces the impedance difference of the terminal 100; at the same time, combined with the skin effect of the current, the current can be conducted along the second welding part 21, the first welding part 14, the contraction section 13 and the buffer section 122, so that in the process of the current being conducted from the contraction section 13 to the first main body part 12, the current conduction direction is smoothly converted and the current is smoothly transmitted, avoiding the sudden change of the current conduction direction, which increases the electromagnetic radiation and aggravates the crosstalk.

[0059] 4. Since the current-carrying area changes in the two processes of the current being transmitted from the first welding portion 14 to the contraction section 13 and from the buffer section 122 to the first main body 12, there is still an impedance difference between the contraction section 13 and the first welding portion 14, and between the buffer section 122 and the first main body 12. Therefore, when the electromagnetic wave of the current is transmitted from the first welding portion 14 to the contraction section 13 and from the buffer section 122 to the first main body 12, the electromagnetic wave is reflected to generate two electromagnetic waves with the same amplitude and wavelength in opposite transmission directions. The electromagnetic wave opposite to the transmission direction of the electromagnetic wave of the current is defined as the reflected electromagnetic wave, and the other is defined as the incident electromagnetic wave. When the length D2 of the contraction section 13 along the front-to-back direction and the length D1 of the buffer section 122 along the front-to-back direction are both greater than or equal to greater than one-quarter of the wavelength (the wavelength at the target transmission frequency of the connector), destructive interference occurs between the reflected electromagnetic wave and the incident electromagnetic wave in the contraction section 13 and the buffer section 122, thereby suppressing the resonance generated by the reflected electromagnetic wave, thereby improving the high-frequency performance of the terminal 100.

[0060] 5. The first inclined surface 215 and the second inclined surface 216 are formed by extending from two oppositely arranged second material thickness surfaces 212 to the first welding portion 14 respectively, and the first inclined surface 215 is obliquely extended to the first welding surface 213 and connected with the first welding portion 14, so that the current can be smoothly transmitted from the first inclined surface 215 to the first welding portion 14; at the same time, the second inclined surface 216 has the first side edge 216a and the second side edge 216b in sequence along the front-to-back direction; the lower edge of the first end face 143 is connected with the first side edge 216a and is arranged flush along the front-to-back direction, so that the current can be smoothly transmitted from the first side edge 216a to the first end face 143, so that the current is smoothly transmitted from the second welding portion 21 to the first welding portion 14, thereby reducing crosstalk.

[0061] 6. By setting the length D3 of the first welding surface 213 along the front-to-back direction to be greater than the length D2 of the contraction section 13 along the front-to-back direction, the first welding surface 213 extends to more than half of the total length of the first welding portion 14 and the contraction section 13 along the front-to-back direction, thereby making the welding between the first welding portion 14 and the second welding portion 21 more stable; and because the width W3 of the contraction section 13 along the left-to-right direction is smaller than the width of the first main body portion 12 along the left-to-right direction, the current-carrying area of ​​the contraction section 13 is smaller. When the potential difference between the two ends of the terminal 100 is constant, the amount of current that the contraction section 13 can carry is reduced. Therefore, the present application avoids the current-carrying length of the contraction section 13 being too long by making the length D3 of the first welding surface 213 along the front-to-back direction greater than the length D2 of the contraction section 13 along the front-to-back direction. Firstly, the current-carrying capacity of the terminal 100 can be improved, and secondly, the pressure generated during the injection molding process of the insulating module M can be avoided from deforming the contraction section 13.

[0062] 7. When the height H1 of the first welding portion 14 along the vertical direction is different from the height H2 of the second welding portion 21 along the vertical direction, the pulling forces on both sides of the welding plane between the first welding surface 213 and the first plate surface 141 welded and fixed thereto are different, which makes the first welding portion 14 and the second welding portion 21 easy to separate; in the present application, the height H1 of the first welding portion 14 along the vertical direction is set to be the same as the height H2 of the second welding portion 21 along the vertical direction, so that the pulling forces on both sides of the welding plane between the first welding surface 213 and the first plate surface 141 welded and fixed thereto are balanced, thereby making the first welding portion 14 and the second welding portion 21 stably fixed; at the same time, combined with the fact that the molten welding thickness N1 of the first plate surface 141 is the same as the molten welding thickness N4 of the first welding surface 213, and the molten welding thickness N3 of the first end face 143 is the same as the molten welding thickness N5 of the second welding surface 214, it is further ensured that the welding strength on both sides of the welding plane between the first welding portion 14 and the second welding portion 21 is balanced, thereby making the first welding portion 14 and the second welding portion 21 stably fixed.

[0063] 8.
