TERMINAL CONNECTION STRUCTURE AND CONNECTION SOCKET

PROBLEM TO BE SOLVED: To provide a terminal connection structure which prevents the spring properties of a terminal block from changing due to repeated use, and can ensure the contact area with a pin terminal, and to provide a connection socket.SOLUTION: In the connection socket having a terminal connection structure, an insertion hole 2 of a pin terminal is provided in the socket body 1, and a terminal block 3 is placed in each insertion hole 2. The terminal block 3 is provided, at a plurality of places spaced apart in the depth direction of the insertion hole 2, with trapezoidal contact parts 7 formed by bending the terminal block 3 at that places convexly. The pin terminal inserted into the insertion hole 2 comes into elastic contact with the top faces of a plurality of contact parts 7 formed in the terminal block 3.
