Connector

A connector used for electrically connecting a first circuit board and a second circuit board, the first circuit board having a positioning portion, the connector comprising:

• an L-shaped body having a lateral side, a bottom and a supporting portion, the supporting portion being used for supporting the first circuit board;
• a first contact elastic piece disposed on and protruding from the lateral side, for being electrically connected with a lateral surface ot the first circuit board, said lateral surface being parallel to the lateral side of the L-shaped body;
• a second contact elastic piece disposed on and protruding from the bottom and electrically connected with the first contact elastic piece, for being electrically connected with the second circuit board;
• and
• a positioning pillar disposed on the supporting portion, the positioning pillar serving as the positioning portion for the first circuit board supported by the supporting portion, so tat the first circuit board is fastened on the supporting portion.

A connector module used for electrically connecting a first circuit board and a second circuit board, the first circuit board having a through hole, the connector module comprising:

• an L-shaped body having a lateral side, a bottom and a supporting portion, the supporting portion supporting the first circuit board;
• a first contact elastic piece disposed on and protruding from the lateral side, for being electrically connected with a lateral surface of the first circuit board, said lateral surface being parallel to the lateral side of the L-shaped body;
• a second contact elastic piece disposed on and protruding from the bottom and electrically connected with the first contact elastic piece, for being electrically connected with the second circuit board;
• a positioning pillar, disposed on the supporting portion and corresponds to the through hole, for pinning through the through hole on the first circuit board supported by the supporting portion, so that the first circuit board is fastened on the supporting portion;
• a base unit for supporting the second circuit board, the L-shaped body and the first circuit board;
• and
• a cover having a positioning hole corresponding to the positioning piUar, the cover being coupled with the base unit, the positioning hole retaining the positioning pillar so that the second contact elastic piece is electrically connected wit the second circuit board firmly.
