Housingless connector

A housingless connector comprising:

• a first housingless connector part including a plurality of beam parts and a plurality of first conductive patterns, the plurality of beam parts having a first metal plate and a first insulating layer formed on the first metal plate, and the plurality of first conductive patterns being formed on the first insulating layer of the plurality of beam parts;
• and
• a second housingless connector part including a beam contact part and a plurality of second conductive patterns, the beam contact part having a second metal plate and a second insulating layer formed on the second metal plate, and the plurality of second conductive patterns being formed on the second insulating layer of the beam contact part, wherein
• when the first housingless connector part and the second housingless connector part are mated, the plurality of first conductive patterns and the plurality of second conductive patterns are electrically and respectively brought into contact, and
• a beam projection is formed between the adjacent second conductive patterns of the second housingless connector part, and the beam projection is inserted between the adjacent beam parts of the first housingless connector part when the first housingless connector part and the second housingless connector part are mated.
