Problems solved by technology
When the electrical connector and the chip are crimped, the ground elastic arm is easy to swing left and right, which is likely to cause a short circuit in contact with the signal terminal; in addition, it is necessary to ensure that the ground elastic arm is sufficiently elastic, The shielding part is set relatively short in the up and down direction, the shielding of the signal terminals is poor, the ability to resist electromagnetic interference is weak, and it cannot meet the needs of high-frequency signal transmission. If the shielding part is set relatively long in the up and down direction, then The length of the ground elastic arm is short, the elasticity is not good, and the positive force on the chip is relatively large

The invention discloses an electric connector suitable for transmitting high-frequency signals between a first butt joint piece and a second butt joint piece. The electric connector comprises a firstshielding piece which extends along the front-back direction; a grounding elastic sheet which is electrically connected with the first shielding sheet and is provided with a main body part and an elastic arm formed by extending from the main body part, wherein the elastic arm is used for being electrically connected with the first butt joint piece or the second butt joint piece and is provided with a through groove, two arm parts located at the left side and the right side of the through groove and a connecting part connected with the two arm parts, the connecting part is located at the end, away from the body part, of the through groove, the first shielding piece is contained in the through groove, and the two arm parts are located at the left side and the right side of the first shielding piece; a signal terminal which is located at one side of the first shielding sheet in the left-right direction, wherein the upper end and the lower end of the signal terminal are used for being electrically connected with the first butt joint piece and the second butt joint piece. Through the arrangement, the grounding elastic sheet is prevented from deflecting leftwards and rightwards and has better elasticity, the signal terminal is shielded, and the signal transmission is facilitated.
Description
【Technical field】 [0001] The invention relates to an electrical connector, especially an electrical connector suitable for transmitting high-frequency signals between two docking parts. 【Background technique】 [0002] At present, the amount of data processed by the chip is continuously increasing. In order to meet the stability of large and high-frequency transmission of electrical signals, more and more dense electrical connectors have become a development trend. The conventional electrical connectors are used for welding on a circuit board. It includes a plurality of shielding parts intersecting each other and an outer frame for fixing the plurality of shielding parts. The plurality of shielding parts are vertically fitted to each other to form a plurality of receiving holes, and each receiving hole accommodates a signal terminal. The signal terminal and the shielding member are fixed on the circuit board, and only air is filled between the shielding member and the signal ...
