摘要： An electrical connector includes an insulating body having a mating slot and multiple accommodating slots are in communication with the mating slot. Multiple terminals are accommodated in the accommodating slots. The terminals include ground terminals. Each terminal includes a connecting portion, an elastic arm, a tail portion, and an extending portion located between the connecting portion and the tail portion. The extending portion of each terminal extends obliquely downward and backward from the connecting portion. A grounding member is provided on the insulating body. The grounding member has a multiple upper and lower extending arms. A length of each upper extending arm is shorter than a length of each lower extending arm in the front-rear direction. The upper and lower extending arms respectively abut the ground terminals, thus shortening the transmission paths of the terminals. The grounding member and the ground terminals are in stable connection, thus reducing the resonance.

摘要： A method for manufacturing an electrical connector is provided. A metal plate is provided, and defines multiple terminals. Each terminal has a base portion and an elastic arm connected to the base portion. A portion of a lower surface of the base portion defines a conducting area. The base portion is cut on the metal plate, thereby forming a cutting slot on the metal plate located at a side edge of the base portion. An insulating body is formed on the metal plate by injection molding, such that the insulating body fills the cutting slot. The insulating body covers only the base portion and not the conducting area and the elastic arm, thereby forming a through hole on the insulating body to expose the elastic arm. Then, the elastic arm is cut on the metal plate, thereby forming a through slot on the metal plate surrounding the elastic arm.

摘要： An electrical connector is used to electrically connect a chip module to a circuit board. The electrical connector has an insulating body, provided with multiple accommodating holes vertically penetrating through the insulating body. An upper surface of the insulating body protrudes upward to form a protruding block located between adjacent ones of the accommodating holes to support the chip module. The protruding block has a first ejector pin surface. The insulating body has a second ejector pin surface adjacent to the protruding block. The first ejector pin surface and the second ejector pin surface are provided for an ejector pin on a mold to push thereon so as to push the insulating body out of the mold. Multiple terminals are correspondingly accommodated in the accommodating holes to be electrically connected to the chip module.

摘要： An electrical connector includes an insulating body, upper row terminals and lower row terminals disposed in the insulating body, and a shielding casing placed on an outer side of the insulating body. The insulating body includes a base portion, and an elevated portion disposed below the base portion. Each of the terminals has a connecting portion located in the elevated portion. A shielding plate integrally extends from a bottom wall of the shielding casing to be located in front of the elevated portion. A back cover integrally bends from a top wall of the shielding casing to be located behind the elevated portion. When the electrical connector is soldered to a circuit board, the shielding plate and the back cover isolate the connecting portion from an external environment, so that the electrical connector is not affected by external electromagnetic interference (EMI) during transmission of high-frequency signals.

摘要： An electrical connector includes at least one electrical module. The electrical module includes: an insulating body, where multiple first accommodating slots are concavely provided on a first side toward a second side of the insulating body; multiple first terminal assemblies, respectively accommodated in the corresponding first accommodating slots; and a first grounding member, having multiple first spokes and multiple second spokes. Each first terminal assembly includes a first insulating block, a pair of first signal terminals, and a first shielding shell. Each first shielding shell has a first shielding side surface exposed to the first side. Each first spoke is in mechanical contact with the first shielding shells of a same electrical module, and each second spoke is in contact with the first shielding side surface of the corresponding first shielding shell, thus achieving conduction between the first shielding shells and the first grounding member.
