Board connector

A board connector comprising:

• a plurality of radio frequency (RF) contacts for transmitting RF signals;
• an insulating part that supports the RF contacts;
• a plurality of transmission contacts coupled to the insulating part and between a first RF contact and a second RF contact, among the RF contacts, such that the first RF contact and the second RF contact are spaced apart from each other in a first axial direction;
• and
• a grounding housing to which the insulating part is coupled, the grounding housing comprising an inner grounding wall facing the insulating part, an outer grounding wall spaced apart from the inner grounding wall, and a grounding connection wall coupled to each of the inner grounding wall and the outer grounding wall,
• wherein
• the inner grounding wall and the outer grounding wall are double-shielding walls that surround the lateral sides of an inner space, and
• the first RF contact and the second RF contact are placed in the inner space surrounded by the double-shielding walls.
