PURPOSE: To improve workability in connecting external wires without interfering with highly dense mounting of various electronic parts in electric equipment.

CONSTITUTION: In a rapid connecting terminal device 30 where external wires can be mounted onto electric equipment capable of making junction to an internal circuit of the electric equipment only by inserting the external wires, the rapid connecting terminal device is provided with lead parts 43b to be connected to the internal circuit of the electric equipment, and is also separated into a fixed body 40 to be installed in the electric equipment and a turning body 50 having external wire installation parts 51 into which the external wires are inserted. The fixed body is provided with support parts 41 having shaft support parts 41a for the turning body and fixed contact parts 43a being exposed in the vicinity of the shaft support parts so as to be continued electrically to the lead parts. The turning body is provided with shaft installation parts 54 to install the turning body in the shaft support parts and turning contact parts 53 capable of making sliding contact with the fixed contact parts in the vicinity of the shaft installation parts so as to be continued electrically to the external wire installation parts.
