The present invention provides a network apparatus for a network of ring topology configuration in which an insertion of an I/O card automatically ring-connects the I/O card and a removal of the I/O card automatically leaves the empty position ring-connected. A connector 1 which is ring-connected to a network includes connection means to be inserted to intervene a signal line. The connection means has a first terminal member and a second connection member. In a first state of the connection means, the first terminal member is in contact with the second terminal member so as to establish an electrical connection between the first terminal member and the second terminal member. In a second state of the connection means, the first terminal member is mechanically disconnected from the second terminal member, which is associated with that the first terminal member is brought into contact with a first connection member of a node so as to establish an electrical connection between the first terminal member and the first connection member, and the second terminal member is brought into contact wint a second connection member of the node so as to establish an electrical connection between the second terminal member and the second connection member.
