Since the screws 4 are tightened by the screws 4 with square washers while being inserted into the connection holes 14a and 14b, the inner walls of the insertion windows 14a and 14b support the reaction force.
Little force acts on the lower end portions 32a, 32b of the power supply terminal fittings soldered to 22b , and there is no adverse effect on the connection with the circuit pattern.

By fixing Ob to the circuit board with three points, the receptacle terminal is prevented from laterally displacing or opening, and is securely fixed to the board 20 in the correct direction. Therefore, the mounting accuracy in the assembling work can be improved, and contact failure from the coil of the solenoid plunger device to the connection plug is less likely to occur. Note that the number of claws of the receptacle terminal may be an arbitrary number of three or more.

Since the mounting of the circuit board in the receptacle case is securely positioned and fixed by the fitting groove independently of the power supply terminal fitting, undesired bending stress does not remain in the power supply terminal fitting,
Even if the power supply terminal fitting is repeatedly damaged by the operation of the solenoid valve, the power supply terminal fitting is not damaged by fatigue, and the mounting position of the circuit board is accurately determined, thereby facilitating the mounting operation.
