PURPOSE:To provide a structure having a grounding electrode in which a plug never easily fall out by providing first and second locking springs and connecting by contact the lead wire of a power source wire and the conductor of grounding wire by the corresponding locking springs. CONSTITUTION:A pair of power source terminal assemblies 2 and a grounding terminal assembly 4 are placed in concave parts 22a-22c of a body 12. Circular tooth rest springs 1, 3 are concentrically disposed in one ends of the terminal plates 2, 4, and contact plates 6, 9 are provided in the other ends thereof. A conductor of the power source wire or a grounding conductor is inserted from the outside, made into spring contact with locking springs 5, 8, and connected by contact to the contact plates 6, 9. The contact is released by the operation of release buttons 7, 10. The top end part of the plug tooth inserted into the spring 1 of the power source terminal assembly is engagingly locked by a protrusion 11, and the above each member is placed in the body 12. Hence, a plug socket having a grounding electrode from which the plug never easily fall out can be obtained. Furthermore, it comprises a cover 14 having a plug tooth inserting port 13, a builtup frame for joining the body 12 to the cover 14, and a locking piece 16 removably locked by a mounting frame. |
