New Description: [New Technical Field] This creation relates to a socket connector, and more particularly to a socket connector for electrically connecting a wafer to a circuit board. [Prior Art] Conventionally, a socket connector for connecting a wafer, such as a central processing unit, has a conductive terminal held therein by a destructive interference fit with the insulating body. Chinese Patent No. 2254847 and No. 200420055027 5 Tigers disclose such socket connectors. As shown in Fig. 1, the conductive terminal 7 of the socket connector disclosed in Chinese Patent No. 02254847. The conductive terminal 7 includes a soldering portion 70, a holding portion 71 extending from the solder portion 7A, a cantilever 72 extending from the other end of the holding portion 71, and a contact portion 73 extending from the end of the cantilever. The opposite sides of the holding portion 71 are provided with a plurality of spurs 710' which are wider than the distance between the two ribs 710 and the side wall of the terminal receiving groove (not shown). Therefore, after the conductive terminals 7 are assembled into the terminal accommodating grooves of the insulative housing, each spur 710 destructively penetrates the inner wall of the terminal accommodating groove to cause destructive interference to accommodate the terminal 7 in the insulating body. However, in such a socket connector, in order to fit the wafer, the number of terminal receiving grooves of each of the insulating bodies is extremely large. Therefore, the destructive interference of the conductive terminal and the inner wall of the insulating body causes stress concentration on the insulating body. This concentrated stress causes the socket connector to be excessively deformed when soldered to the circuit board, which affects the soldering quality and leads to the performance of the socket connector. And the service life is reduced. In view of the above, the conventional receptacle connector requires further improvement. [New Content] *M327564 The purpose of this creation is to provide a socket connector in which the conductive terminals are relatively stable in the green receiving holes of the respective terminals without causing insulation. Deformation ^ To achieve the above purpose, the present invention provides The following technical solution: the socket connector includes: an insulating body penetrating through the plurality of terminal receiving slots, and a plurality of receiving holes in the corresponding terminal receiving slots (4) conductive terminals i terminal receiving slots respectively having an upper opening and Lower opening.

The second catch portion is located below the second limit portion and is restricted from moving upward. In an embodiment, the terminal receiving groove has an opposite first side wall and a first wall connecting the first and second side walls to form a third side wall and a fourth side wall; the second limiting portion and the second limit The positions are all disposed on the third side wall. The opposite end of the base connecting the tandem W is a free end, and the first retaining portion extends downward from the outer side of the free end and at an angle to the base. The first limiting portion is corresponding to the first one, the holding portion is recessed at the end of the third side wall at the upper opening, and the second holding portion is connected to the opposite side of the _ end of the welded portion from the base portion. The base is extended at an angle of one. The second limiting portion is a limiting step corresponding to the second clamping, and the second sidewall is adjacent to the lower opening. A third limiting portion is protruded from the first wall and the first wall, so as to form a card slot with the third side.

The conductive terminal further • M327564 includes a first connecting portion connecting the base portion and the elastic arm, and a second connecting portion connecting the base portion and the soldering portion. Compared with the conventional socket connector, the conductive terminal of the socket connector of the present invention is provided with a holding portion at the base portion and cooperates with a corresponding limiting portion disposed in the terminal receiving groove to jointly hold the conductive terminal relative to the terminal receiving slot. There is no need to apply a strong force to the terminal receiving groove to avoid deformation of the insulating body.
