PURPOSE:To facilitate the maintenance of a meter by providing a receptacle provided with a conductive material, which is connected to a terminal part with elastic contact in a meter for process instrumentation of a plant and fitting a receptacle having a conductive part to this receptacle. CONSTITUTION:A current indicating meter 11 consists of an indicating part 12 as a main body and a terminal part 13 which can be connected to another meter, and both parts are freely attachable and detachable, and the indicating part 12 has a pair of projecting insulating plugs 14 on the joint surface, and conductive materials are stuck to their outside faces. The terminal part 13 has a pair of receptacles 16, to which plugs 14 are fitted, on the joint surface, and a conductive material 17 which is brought into contact with the face of the conductive material 15 is stuck to each receptacle 16 from the inside face to the bottom face, and a flat spring 18 is buried in the terminal part 13, and both ends 18a of this spring 18 are led into receptacles 16 and are allowed to face the bent ends 17a of conductive materials 17. When the indicating part 12 and the terminal part are joined, both ends 18a of the spring 18 are kept away from conductive materials 17a, and conductive materials 15 and 17 are brought into contact with each other, and input terminals 19a and 19b are connected to the circuit of the indicating part 12 through conductive materials 17 and 15. |
