Electric connector

Abstract

The invention discloses an electric connector. The electric connector is used for electrically connected with an electronic element and a circuit board, and is characterized in that the electric connector comprises an insulation body, at least one first terminal and at least one second terminal. Each first terminal comprises a base part accommodated in the insulation body, and a first elastic armwhich upwards extends from the base part and is at least partially arranged on the insulation body and used for being in abutted contact with the electronic element. Each second terminal comprises a fixed end and second elastic arm, wherein the fixed end is connected with the second elastic arm. Each fixed end is at least partially arranged on the insulation body and welded to the corresponding first elastic arm. Each second elastic arm is in sliding contact with the corresponding first terminal.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector for connecting a chip module to a circuit board with a terminal of double conduction channels. Background technique [0002] A conventional electrical connector has an insulating body, a plurality of terminals are accommodated in the insulating body, each terminal has a base part accommodated in the insulating body, and the upper end of the base extends upwards out of a main spring arm above the insulating body , the upper end of the main elastic arm has a contact portion for abutting contact with a chip module, the lower end of the base portion extends upwards from an auxiliary elastic arm on the upper surface of the insulating body, and the free end of the auxiliary elastic arm has a contact, upward When the chip module abuts against the main elastic arm, the main elastic arm moves downward, and the auxiliary elastic arm slides along the main elastic arm and su...

Problems solved by technology

[0003] However, the contact is the elastic end of the auxiliary elastic arm, which can slide freely along the main elastic arm, and both the main elastic arm and the auxiliary elastic arm are located on the upper surface of the insulating body. The arm and the auxiliary elastic arm are easily affected by external force, so that the auxiliary elastic arm is easily deformed and the contact is deflected left and right relative to the main elastic arm, resulting in a gap between the contact and the main elastic arm, resulting in the auxiliary elastic arm and the main elastic arm. The main elastic arms are separated, so that when the main elastic arm is pressed down, the auxiliary elastic arm does not support the main elastic arm upwards, which leads to the downward pressure of the chip module only being borne by the main elastic arm, and the elasticity of the main elastic arm Excessive deformation makes the electrical transmission between the electrical connector and the chip module unstable

At the same time, the electrical signal of the conductive terminal can only be transmitted to the conduction part through the main elastic arm, and the auxiliary elastic arm forms an electrical stub, which is an invalid path for transmitting electrical signals, thereby increasing the impedance of the terminal, which is not conducive to the electrical performance of the electrical connector
