The power supply terminal plate 7 is provided with two connection pieces 12 projecting integrally therefrom, and a substantially U-shaped blade receiving spring 13 having elasticity is fixed to the connection piece 12 with a caulking rivet 14. The upper part of the pair of blade receiving spring pieces 13a of the blade receiving spring 13 is formed in an arc shape, and a projection is provided on the inner surface, and the hole of the plug blade of the inserted plug is fitted to prevent it from falling off. It has a structure. Here, the blade receiving spring 13 uses brass having high mechanical stress.
A projection 15 is integrally formed substantially at the center of the power supply terminal plate 7, and the projection 15 comes into contact with a rib on the ceiling surface of a cover 21 covering the upper surface of the body 1 so that the power supply terminal plates 7, 8 To prevent floating.

U-shaped terminal strips 9 are formed on both sides of the ground terminal plate 16 in the same manner as the power supply terminal plate 7, and a locking spring 10 is also provided. The ground terminal plate 16 is integrally formed with a blade receiving spring 17 for a ground electrode, and the upper portions of the pair of blade receiving spring pieces 17a are formed in an arc shape. still,
The power supply terminal plates 7, 8 and the ground terminal plate 16 are made of iron-containing copper having high conductivity.

On the upper surface of the cover 21, three ones corresponding to the blade receiving springs 13 and 17 are provided.
A set of blade insertion openings 22 is formed. The cover 21 is covered on the upper surface of the body 1, and the both are joined by the swaging stud 23. Steps 24 are formed on both sides of the cover 21, and a mounting step is provided at the center of the step 24.
25 are formed.

When the body 1 and the cover 21 are connected, one wire insertion opening 26 is formed on both side surfaces at both ends.

2 and 3 show the outlet body A as a caseway.
The case where it is attached to 30 is shown. The caseway 30 has a U-shaped cross section, is a long object, and has an open front surface. The outlet main body A is inserted from the cutout opening 32 in which the side piece 31 on the front surface of the caseway 30 is partially cut out, and the outlet main body A is moved in the longitudinal direction of the caseway 30 by using a wood screw 33 at an arbitrary position. Fix the outlet body A. Here, the third on both sides of the back of the body 1 of the outlet body A

The door 40 is provided between the inner opening of the blade and the blade receiving springs 13 and 17. The door 40 is formed in a substantially L shape, and a flat spring 41 is disposed on the back. At the center of the spring 41, a spring piece 42 is formed by cutting out.
Is closed to close the blade insertion port 22.

When the plug of the plug blade is inserted, the tip of the plug blade of the plug presses against the inclined surface 40a on the upper surface of the door 40, and the door 40 is tilted outward against the urging force of the spring piece 42 so that the blade of the plug blade is Smooth insertion into the receiving springs 13 and 17 is enabled. Here, after inserting the plug blade, by rotating the plug by a predetermined amount, the hole of the plug blade is fitted into the projection of the blade receiving spring 13 and the plug is prevented from coming off. When the plug is not inserted, the blade insertion port 22 is closed by the door 40, so that invasion of small animals such as slugs can be prevented, and accidents such as short circuit can be prevented.

[Effect of the invention]

In the present invention, as described above, a pair of conductive power supply terminal plates having a power-side blade receiving spring, a conductive ground terminal plate having a ground-side blade receiving spring, and both terminal plates are disposed. In a power outlet provided with a body and a cover disposed on the upper surface of the body and having a blade insertion hole corresponding to each blade receiving spring, the blade receiving spring of the power supply terminal plate is formed of brass and a ground terminal. Since the blade receiving spring of the plate is made of iron-containing copper, and the cover is formed on the power supply terminal plate, a projection is formed on the power supply terminal plate so as to abut against the ceiling surface of the cover when the cover is laid over the body to prevent the power supply terminal plate from floating. The mechanical strength of the blade receiving spring of the power supply terminal plate is increased to ensure stable contact with the plug blade even if the plug blade is repeatedly inserted and removed, and the conductivity of the ground terminal plate can be increased. That can be easily grounded. Form and the projections, in which the effect capable of preventing the floating of the power terminal plate in contact with the ceiling surface of the cover when Kutsugae設 the cover body.
