New Description: [New Technology Field] [0001] The present invention relates to an electrical connector, and more particularly to an electrical connector for electrically connecting a wafer module to a printed circuit board. [Prior Art] [0002] With the rapid development of electronic technology, electrical connectors are widely used for electrically connecting chip modules to printed circuit boards. A conventional planar grid array electrical connector includes an insulative housing and a plurality of electrically conductive terminals received in the insulative housing. The insulating body is provided with a receiving hole for receiving the conductive terminal. The conductive terminal includes a base, a welded portion extending downward from the base, and a resilient arm extending upward from the base. The end of the elastic arm is provided with a contact portion electrically connected to the wafer module. With the development trend of miniaturization of electrical connectors, the distance between the terminals and the terminals is getting smaller and smaller, and the corresponding electromagnetic interference is becoming more and more serious, which affects the contact quality of the electrical connectors. [0003] Therefore, it is necessary to provide an improved electrical connector to overcome the deficiencies of the related art. [New content] [0004] The technical problem solved by this creation is to achieve the effect of electromagnetic shielding by setting the metal frame and firmly positioning the metal frame and the base. In order to solve the foregoing technical problems, the present invention provides an electrical connector for electrically connecting a chip module to a printed circuit board, including a base, a plurality of conductive terminals received on the base, and a base disposed on the base The metal frame body comprises a top surface, a lower surface opposite to the upper surface, and a side surface connecting the upper surface and the lower surface, the metal frame body is provided with a plurality of side walls, and the side double is provided with a plurality of holes. The third page/total 11 page form No. A0101 M424673, the positioning post of the through hole is provided on the side of the base [0006] Compared with the prior art, the present electrical connector has the following advantages: the metal frame is provided with a hole, and is integrally formed with the base. The plastic flows through the hole to form a positioning post, so that the metal frame and the base are firmly positioned to achieve electromagnetic shielding while enhancing the holding effect of the metal frame and the base. [Embodiment] [0007] Referring to the first to third figures, the present electrical connector 1 is used to electrically connect a chip module (not shown) to a printed circuit board (not shown). The electrical connector 100 includes a base 2, a plurality of conductive terminals 3 received in the base 2, and a metal frame 1 disposed on the base 2. The metal frame 1 is fixed to the base 2 by integral molding. The base 2 is provided with an upper surface 20, a lower surface 21 opposite to the upper surface 20, and a side surface 22 connecting the upper surface 20 and the lower surface 21. The base 2 is further provided with a plurality of upper surfaces 20 extending from the lower surface 21 The receiving hole 201 and the positioning post 221 extending from the side surface 22. The conductive terminal 3 is received in the receiving hole 201 of the base 2, and includes a base portion 30, an elastic portion 33 extending upward from the base portion 30, an elastic portion 32 extending downward from the base portion 30, and an upward extending portion from the base portion 30. The upper end of the upper elastic portion 33 of the holding portion 31 ^ is provided with an upper contact portion 331 , the lower end portion of the lower elastic portion 32 is provided with a lower contact portion 321 , and the holding portion 31 is provided with a barb 310 . The upper contact portion 331 extends from the upper surface 20 of the socket 2 to be electrically connected to the wafer module, and the lower contact portion 32i extends from the lower surface 21 of the base 2 to be electrically connected to the printed circuit board. Remaining 3 ^ 基座 The susceptor 2 is held such that the conductive terminal 3 is securely positioned within the susceptor 2. [0010] The metal frame 1 is embedded in the susceptor 2 and is provided with a plurality of side walls 11. Four of the form numbers A0101 Page 4 of 11 M424673 The side walls 11 are respectively attached to the side 2 2 of the base 1. The plurality of side walls 11 are surrounded by a plurality of openings 10. In the present embodiment, the opening 10 and the receiving hole 2〇1- are opposite, and the number of the openings 10 can also be smaller than the number of the receiving holes 201, and the number of the openings 10 can be set according to specific requirements. The side wall 11 is provided with a plurality of holes 111 corresponding to the positioning posts 221 of the base 2. During the process of forming the metal frame 1 and the base 2, the plastic flows through the hole 111 of the metal frame 1 to form the positioning post 221 ' of the base 2 to firmly position the metal frame 1 and the base 2 together. In order to maximize the effect of electromagnetic shielding, the position of the aperture 1 on the metal frame 1 is lower than the position of the barb 310 of the conductive terminal 3, and the size of the hole ill is less than 0.5 mm.
