Electric connector

Abstract

The invention discloses an electric connector; the electric connector is used for being mounted to a circuit board to be electrically connected with a chip module, wherein the electric connector comprises an insulating body equipped with a plurality of terminal holes, and a plurality of conducting terminals which are contained in the terminal holes in a one-to-one correspondence mode; the insulating body has an upper surface and a lower surface which are opposite to each other; the terminal holes penetrate through the upper surface and the lower surface; each conducting terminal comprises a butt joint arm and a welding arm, wherein the butt joint arm is used for being in contact with the chip module, and the welding arm is used for being welded to the circuit board and extends up and down;each butt joint arm comprises a first main body portion and an elastic arm, wherein the first main body portion is fixedly clamped in the corresponding terminal hole, and each elastic arm extends andbends upwardly from the first main body portion to extend out of the upper surface; each butt joint arm and the corresponding welding arm are independent and are arranged at intervals; and the elastic arms move when the chip module presses down to prop against the welding arms downwardly so as to form electric conduction, and therefore the current path between the chip module and the circuit board is shortened, and the high-frequency performance of the electric connector is improved.

[0002] Chinese Utility Model Patent No. CN206283019U discloses an electrical connector for mounting on a circuit board to electrically connect a chip module, which includes an insulating body and conductive terminals held on the insulating body. The holding part of the insulating body, the elastic arm bent upward from the holding part and extending out of the upper surface of the insulating body, and the welding part extending downward from the holding part to be welded to the circuit board, when the chip module presses down on the elastic When the arms are connected, the conductive terminals form an electrical connection between the chip module and the circuit board. Due to the current requirements for the transmission speed of high-frequency signals for electrical connectors are continuously increasing, and the elastic arms of such conductive terminals are due to abutment It has to be set in a curved long arm shape due to the demand, which will cause the current path of the terminal to be too long, which will affect its high frequency characteristics and limit its transmission rate
