Description

Technical Field

[0001] This utility model relates to a connector common grounding assembly structure, specifically an upper connector having a first spacer with a plurality of first contacts between a first terminal block and a second terminal block, wherein the plurality of first contacts simultaneously contact a plurality of grounding terminals of a first terminal group and a second terminal group, thereby forming a multi-point common grounding function of the first spacer, the first terminal group, and the second terminal group; similarly, the lower connector can also form a multi-point common grounding function of the second spacer, the third terminal group, and the fourth terminal group, thereby reducing the overall reflection loss and insertion loss of the stacked connector, and making the high-speed signal transmission characteristics better and more stable. Background Technology

[0002] Electronic connectors are widely used in various communication and audio-visual equipment as components for transmitting and connecting electronic signals. Common standard connector sockets include RJ-11 (telephone line socket), RJ-45 (network cable socket), USB (Universal Serial Bus), IEEE1394 (Serial Bus), RF (Radio Frequency), Pin-header, HDMI (High Definition Multimedia Interface), and DisplayPort, among other types.

[0003] Among the aforementioned connectors, the DisplayPort (DP) connector is widely used in image signal transmission. A high-frequency DP connector consists of an insulating body, multiple upper row terminal pairs housed within the insulating body, and a lower row of terminals. The aforementioned DP connector's upper and lower terminal structure design is inadequate, failing to achieve optimal impedance matching and thus failing to reduce high-frequency signal reflection. This significantly compromises the integrity and stability of high-frequency signal transmission. Furthermore, its complex manufacturing process results in long production times and ineffective cost reduction, requiring improvement from those in the industry. Utility Model Content
