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 electrical connector suitable for transmitting high-frequency signals between a first docking part and a second docking part, comprising: a first shielding sheet extending along the front and rear directions; a grounding elastic sheet electrically connected to the first shielding sheet Sexual connection, the grounding shrapnel has a main body and an elastic arm extending from the main body, the elastic arm is used to electrically connect the first docking piece or the second docking piece, the elastic arm is provided with a through groove, located on the left and right sides of the through groove The two arm parts and the connection part connecting the two arm parts, the connection part is located at the end of the through groove away from the main part, the first shielding piece is accommodated in the through groove, and the two arm parts are located at the left and right sides of the first shielding piece side; the signal terminal is located on one side of the first shielding piece in the left-right direction, and the upper and lower ends of the signal terminal are used to electrically connect the first butt joint and the second butt joint. Such setting prevents the ground shrapnel from swinging left and right while having better elasticity, and realizes shielding of the signal terminals, which is beneficial to signal transmission.
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 ...
