An edge connector is disclosed, having a configuration in which board contacting portions of terminals coming into contact with both ends of the board are displaced, an overall spring portion of each terminal applying an biasing force to the board contacting portions are displaced, and the surface of a cover member displacing the spring portion is configured as a sloped surface. Due to this configuration, it is possible to apply a stable biasing force to the board contacting portion without plastically deforming the terminals and to bring the board contacting portion of the terminal into secure contact with the board even when the thickness of the board varies greatly.
1. An edge connector comprising:
a housing having one end which is configured to be engaged, by fitting, with a counterpart connector body;
terminals which are fitted in the housing, in which each of the terminals includes a connector contacting portion that is configured to come into contact with a counterpart connection portion of the counterpart connector body, and a board contacting portion that is configured to protrude from the other end of the housing in a direction opposite to the counterpart connector body and come into contact with a connection portion of a board; and
a cover member which includes a first cover member and a second cover member arranged so as to oppose both surfaces of the board, and which is provided at the other end of the housing so as to accommodate the board contacting portions of the terminals, wherein:
the first cover member is fixed to the housing, and the second cover member is coupled with the first cover member by a fastening means;
the fastening means fastens the first cover member and the second cover member with each other, whereby the edge connector is connected to the board;
the cover member is provided with a terminal accommodation groove that accommodates the board contacting portions of the terminals; and
the board contacting portion includes a cantilever-like contacting upper-arm portion which has one fixed end and is configured to extend obliquely towards the center in the thickness direction of the housing, a bent projection portion which is formed at the free end of the contacting upper-arm portion so as to come into contact with the connection portion, a spring portion which is configured to extend obliquely from the bent projection portion in a direction away from the center in the thickness direction of the housing, and an abutting portion which is formed at the free end of the spring portion so as to come into abutting contact with an inner wall of the terminal accommodation groove.
2. The edge connector according to claim 1 , wherein the inner wall of the terminal accommodation groove includes a sloped pressing surface that is approximately parallel to the spring portion, and the abutting portion comes into abutting contact with the sloped pressing surface.
