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 chip module to a circuit board. [Prior Art] [0002] The planar grid array electrical connector is widely used in the electronic field to electrically connect the wafer module to the circuit board to realize signal and data transmission between the chip module and the circuit board. Such a technique is disclosed in "Nonlinear Analysis Helps Design LGA Connectors" (Connector Spe-cifier, Februsy 200 1). The electrical connector includes a body and a terminal received in the body. When the electrical connector connects the chip module to the circuit board, the upper and lower contact points of the electrical connector are respectively connected to the chip module and the circuit board. The conductive sheets are crimped to form a signal transmission between the chip module and the circuit board. [0003] However, with the continuous development of electronic technology, the arrangement density of the conductive chips of the chip module and the circuit board is increasing, and the size and height of the planar grid array electrical connector used in the field are increasingly Small, and the terminal arrangement density is required to be more and more dense. In this case, when the electrical connector is connected to the signal transmission between the chip module and the circuit board, it will inevitably cause electromagnetic interference when the terminal with small adjacent spacing transmits signals, and electromagnetic interference occurs between adjacent signals. It will definitely affect the quality of signal transmission between the chip module and the board. Therefore, in order to ensure signal transmission integrity between the chip module and the board, an electrical connector having a shielding device for preventing electromagnetic interference becomes particularly important.

The anti-electromagnetic interference terminals are generally assembled into the insulative body by means of interference embedding. However, since the side walls of the insulating body are generally weak, the anti-electromagnetic interference terminals are likely to cause plastic cracks or even damage to the side walls of the insulating body after being incorporated into the side wall of the insulating body.
