[0037] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0038] Please refer to Figures 1 to 8 As shown, an electrical connector is used to connect a chip module (not shown) such as a central processing unit (CPU) to a circuit board (not shown). The electrical connector 100 includes an insulating body 1 and a plurality of conductive terminals 2 installed in the insulating body 1. In this way, the electrical connection between the electrical connector 100 and the chip module is achieved through the contact between the conductive terminals 2 and the chip module.

[0039] The insulating body 1 has an upper surface 11 and a lower surface 12 opposite to each other and a plurality of terminal slots 13 passing through the upper and lower surfaces 11 and 12 . The conductive terminals 2 are received in the terminal slots 13 .

[0040] The conductive terminal 2 includes a first body portion 21 and a second body portion 22 simultaneously housed within the terminal slot 13, an elastic portion 23 that bends from the first body portion 21 and extends beyond the upper surface 11 of the insulating body 1, a first soldering portion 24 extending downward from the first body portion 21, and a second soldering portion 25 extending downward from the second body portion 22. The first and second body portions 21, 22 are arranged at an angle to each other and connected by a transverse bridge portion 26. The elastic portion 23 is provided with an upwardly protruding contact portion 27. The first body portion 21 and the second body portion 22 are arranged perpendicular to each other. The first body portion 21 is provided with a first bent portion 211 connected to the first soldering portion 24, and the first bent portion 211 is bent downward. The lower portion of the second body portion 22 is provided with a second bent portion 222 that bends downward, a third bent portion 223 that bends upward from the lower end of the second bent portion 222, and a fourth bent portion 224 that bends downward and extends from the third bent portion 223. The second welding portion 25 is connected to the lower end of the fourth bent portion 224. The second body portion 22 is provided with barbs 221 that extend horizontally to both sides to interfere with the terminal slot 13 and secure the conductive terminal 2 within the terminal slot 13. The upper portion of the second body portion 22 is provided with a strip connection portion 225 for connecting a strip.

[0041] The elastic portion 23 is provided with two upwardly projecting contact portions 27 at its free end. These contact portions 27 are spaced apart and parallel to each other. The presence of these two contact portions 27 provides two points of contact between the conductive terminal 2 and the chip module, thereby enhancing signal transmission efficiency. A slot 231 extends through the thickness of the elastic portion 23. The width of the elastic portion 23 is greater than the width of the contact portions 27. The slot 231 is located in the stress concentration area of the conductive terminal 2, and its length, width, and position can be adjusted according to actual needs.

[0042] The first soldering portion 24 and the second soldering portion 25 are arranged adjacent to each other, and the first soldering portion 24 and the second soldering portion 25 are located in the same horizontal plane. The first soldering portion 24 and the second soldering portion 25 are both soldered to the same solder ball 3. With this arrangement, when the solder ball 3 is bonded to the circuit board, current can flow into the circuit board through the second body portion 22, forming a closed state, which can effectively reduce the capacitance effect in the conductive terminal 2. At the same time, the first body portion 21 and the second body portion 22 form a parallel circuit, reducing signal loss during high-frequency signal transmission and improving the quality of high-frequency signal transmission. The first soldering portion 24 has a first inner side 241 facing the second soldering portion 25, and the second soldering portion 25 has a second inner side 251 facing the first soldering portion 24. The first inner side 241 and the second inner side 251 are arranged adjacent to each other, parallel to each other, and spaced apart. The first inner side 241 and the second inner side 251 are arranged face to face. The first soldering portion 24 has a first outer edge 242, which is the side excluding the first inner edge 241; the second soldering portion 25 has a second outer edge 252, which is the side excluding the second inner edge 251. The first soldering portion 24 extends and widens toward the first outer edge 242, and the second soldering portion 25 extends and widens toward the second outer edge 252, so that the first soldering portion 24 and the second soldering portion 25 can better contact the solder ball 3.

[0043] In summary, the beneficial effects of the electrical connector 100 described in the present invention are as follows: the present invention is provided with a first welding part 24 and a second welding part 25, and the first welding part 24 and the second welding part 25 are both in contact with the solder ball 3. The current can flow into the circuit board through the second main body part 22, forming a closed state, effectively reducing the capacitance effect of the conductive terminal 2; at the same time, the current flows into the circuit board through the first main body part 21 and the second main body part 22 at the same time, so that the first and second main body parts 21 and 22 form a parallel circuit, which can reduce the signal loss of high-frequency signal transmission and improve the quality of high-frequency signal transmission.
