Terminal Module, Electrical Connection Module, Electrical Connection Assembly and Connector

An electrical connection module, comprising:

• a terminal module, comprising:
• a row of terminals including multiple pairs of signal terminals and multiple grounding terminals arranged in a transverse direction, with one grounding terminal set between adjacent pairs of signal terminals, each terminal comprising a cantilever portion and a welding portion opposite in a longitudinal direction, and a fixing portion located between the cantilever portion and the welding portion;
• and
• a terminal holder which is injection molded onto the fixing portions of the row of terminals, so that the row of terminals and the terminal holder become an integrated piece, multiple windows corresponding to the multiple pairs of signal terminals are formed on the terminal holder, and the windows penetrate the terminal holder in a height direction, so that a part of the fixing portions of each pair of signal terminals is exposed through the window;
• and
• multiple cables arranged in a transverse direction, wherein the signal cables of the multiple cables are respectively soldered to the top surfaces of the welding portions of the multiple signal terminals of the terminal module, and the grounding cables of the multiple cables are respectively soldered to the top surfaces of the welding portions of the multiple grounding terminals of the terminal module.
