High-frequency high-speed transmission cable module and upper cover of the cover body thereof

A high-frequency high-speed transmission cable module, comprising:

• a cover body, comprising an upper cover and a lower cover, the upper cover further comprising a main body and a heat dissipation block, the main body having a first end portion and a second end portion in a length direction of the main body, the lower cover further having a first end portion and a second end portion in a length direction of the lower cover;
• a cable, one end of the cable being accommodated in the second end portion of the main body and the second end portion of the lower cover in the cover body;
• a control module, disposed inside the first end portion of the main body and the first end portion of the lower cover in the cover body and located under the heat dissipation block;
• wherein the first end portion of the main body is disposed with a through hole, an inner wall of the through hole is disposed with a protruding support portion, the protruding support portion divides the through hole into an upper passage and a lower passage connected by a connecting passage, the upper passage passes through a top surface of the first end portion of the main body, and the lower passage passes through a bottom surface of the first end portion of the main body;
• wherein the heat dissipation block is embedded in the through hole and includes an upper portion, a middle portion and a lower portion, the upper portion is located in the upper passage and exposed through the top surface of the first end portion of the main body with an edge portion of the upper portion in contact with and supported by the protruding support portion, the middle portion is disposed in the connecting passage, the lower portion is located in the lower passage, and a portion of a bottom surface of the middle portion is exposed directly above a topmost surface of the control module;
• and
• wherein the control module is located under the lower portion of the heat dissipation block, a top surface of the upper portion of the heat dissipation block is in contact with heat dissipation fins of a casing to transfer heat generated by the control module through the heat dissipation block to the heat dissipation fins, and a bottom surface of the edge portion abuts against the protruding support portion so that the protruding support portion and the first end portion of the main body absorb and transfer the heat to the second end portion of the main body and dissipate the heat through a plurality of grooves formed on the second end portion of the main body.
