Problems solved by technology
However, assembly and cooperation between the connecting part and the contact arm is required, resulting in a long production cycle, and the two are easy to collide with each other, causing the terminal to be broken and resulting in an increase in the defective rate. More importantly, there is a problem between the connecting part and the contact arm. New contact interface, resulting in high terminal impedance and poor high frequency performance

Embodiment Construction
[0038] In order to facilitate a better understanding of the purpose, structure, features, and effects of the present invention, the present invention will now be further described with reference to the drawings and specific embodiments.
[0039] Such as Figure 1 to Figure 4 As shown, the electrical connector 100 according to the first embodiment of the present invention is used to electrically connect a chip module 13 to a circuit board 15. Its main components include: a plurality of terminals 4 and a plurality of terminals 4 的一 Insulating body 1.
[0040] Such as figure 1 As shown, the terminal 4 is punched out of a thick and thin material P having a thin portion p2 and a thick portion p1 protruding from the thin portion p2.
[0041] Please continue to refer figure 1 with figure 2 The multiple terminals 4 include multiple signal terminals 4a and multiple power terminals 4b, and the signal terminals 4a and the power terminals 4b have the same structure. In other embodiments, the pl...

The invention discloses an electric connector which is used for electrically connecting a chip module with a plurality of conductive sheets to a circuit board and comprises an insulating body and a plurality of terminals. The insulating body is provided with an upper surface, a lower surface and a plurality of terminal holes, wherein the upper surface faces the chip module, the lower surface facesthe circuit board, and the terminal holes penetrate the upper surface and the lower surface. Each terminal is provided with a connecting portion correspondingly positioned in the corresponding terminal hole, the connecting portion extends to form a conducting portion for conducting the circuit board, the connecting portion is bent upwards and extends to form at least one elastic arm extending upwards out of the corresponding terminal hole, and each elastic arm is bent upwards and extends to form a contact portion. When the chip module is pressed down, the bottoms of the conductive sheets areabutted downwards to the tops of the contact portions, and the elastic arms are compressed downwards and deformed. The contact portions, the elastic arms, the connecting portions and the conducting portions are integrally formed, the thickness of each connecting portion is larger than that of the corresponding contact portion, the impedance of the terminals is adjusted to a proper range, the requirement of the electric connector for impedance matching is met, and the high-frequency transmission performance of the electric connector is improved.
Description
【Technical Field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector with improved high-frequency performance. 【Background technique】 [0002] The Chinese patent with the patent number CN201420377264.4 discloses an electrical connector, including an insulating body and a plurality of terminals arranged on the insulating body, each terminal has a contact arm, the contact arm has an assembly part, and An elastic part of the assembling part bent upward is used to contact a chip module, and a connecting part is assembled to the contact arm, the lower end of the connecting part is connected to the assembling part, and the upper end is used to connect to a material belt. However, the connection part and the contact arm need to be assembled and cooperated, which leads to a long production cycle, and the two are easy to collide with each other, which causes the terminal to be broken, resulting in an increase in the rate of defective products...
