Plug connector coupled to receptacle connector

A plug connector coupled to a receptacle connector, the plug connector comprising:

• a conductor for signals;
• a ring-shaped conductor for ground, the conductor surrounding the conductor for signals;
• a ring-shaped insulator surrounding the conductor for signals and being surrounded by the conductor for ground, and insulating between the conductor for signals and the conductor for ground;
• a lower body;
• and
• an upper body coupled onto the lower body,
• wherein the conductor for signals comprises a lower portion protruding below a first portion on the insulator, a middle portion inserted into a hollow portion of the first portion, and an upper portion protruding above the first portion,
• wherein the conductor for ground comprises a lower portion protruding below the first portion and an upper portion surrounding the first portion,
• wherein the lower body comprises a lower housing having a hollow portion that is vertically opened,
• wherein the upper portion of the conductor for ground is accommodated in the hollow portion, and the lower portion of the conductor for ground and the lower portion of the conductor for signals are exposed downward through the hollow portion,
• wherein the upper body comprises an upper housing facing the lower housing and having a hollow portion opened downwards so that the hollow portion forms a space around the upper portion of the conductor for signals,
• wherein the lower body further comprises a lower guide portion configured to guide a cable toward the conductor for signals from one side of the lower housing, and the upper body further comprises an upper guide portion facing the lower guide portion and configured to guide the cable toward the conductor for signals from one side of the upper housing, and
• wherein a lower neck portion and an upper neck portion protrude respectively from one sides of the lower guide portion and the upper guide portion to surround an exposed outer conductor of the cable at a distance, and a soldering portion is formed between inlet portions of the lower neck portion and the upper neck portion and the outer conductor.
