Abstract

PROBLEM TO BE SOLVED: To turn off both of movable and fixed terminals in an unplugged state to prevent an electric shock from occurring, and to move the movable terminals in a plugged state to feed power by connecting plug blades to blade receivers by the insertion of the plug blades of a plug and by bringing the movable terminals in contact with the fixed terminals. SOLUTION: A sliding rod 23 which is constituted of an insulating body and has an edge and a rear end inserted into a through hole 17 is provided with movable contact plates 28 and movable terminals 29 to a fitting piece 22 projected to the both sides, and blade receivers 31 having contact pieces 30. When a plug 34 is plugged in a socket, plug blades are pushed in toward the blade receivers 31 and the sliding rod 23 is pushed down against a spring 27 so as to bring the movable terminals 29 in contact with fixed terminals 19. At the same time, a guide part in the rear end of the sliding rod 23 touches the wall of an insulating case and the plug blades and the blade receivers 31 are brought in contact under a sufficient state. When the plug 34 is drawn out, the movement of the sliding rod 23 is regulated by abutting on the front plate of a stopper 25 so that the plug blades and the blade receivers 31 are released.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outlet device attached to, for example, a top plate or a sink of an electric kotatsu.

[0002]

2. Description of the Related Art Some electric appliances are provided with an outlet on the top plate of the electric kotatsu or on the side wall of the wash basin so that other electric appliances can be used.

For example, a personal computer or a fluorescent light plug is inserted into an outlet attached to a top plate of an electric kotatsu,
A hair dryer and an electric razor are plugged into the outlet attached to the sink.

[0004] However, the outlet attached to the top plate of the electric kotatsu is designed so that when the user enters the electric kotatsu, the outlet is located just around the chest, so that a child can insert a pencil or other foreign matter and insert the plug. Inability to do so or risk of electric shock.

Similarly, in the case of an outlet attached to a washstand, there is a danger that foreign matter may be inserted or water may enter the outlet and cause an electric shock when the plug of the electric razor is inserted.

In order to prevent such a danger, a slide plate is provided on the front of the outlet as shown in, for example, Japanese Patent Application Laid-Open No. Hei 6-260239. The one that prevented electric shock beforehand was proposed.

[0007]

However, in the case of the prior art as described above, the moving mechanism of the slide plate provided on the front side of the outlet becomes complicated, and the two slide plates are provided. It is necessary to design the slide plate to move synchronously, which is troublesome.

If the two slide plates do not move in a timely manner, the insertion blade of the plug may not be securely inserted, or the plug may be oblique and one of the insertion blades may be greatly exposed, resulting in electric shock. There was a danger.

In particular, when two metal rods are inserted into an outlet at the same time, there is a danger that the two slide plates move and the human body becomes a conductor, resulting in electric shock.

According to the present invention, when the plug is not inserted, the movable terminal and the fixed terminal are separated from each other to prevent the electric shock by being cut off, and when the plug is inserted, the movable terminal moves and comes into contact with the fixed terminal so that power can be supplied. I do.

[0011]

According to the present invention, there is provided a recess provided on a side wall of a base, a fixed terminal having a different polarity which is insulated and fixed in the recess, and movably provided in the recess. And a movable contact plate having a different polarity having a movable terminal and having a movable terminal. When the insertion blade of the plug is inserted, the insertion blade and the blade receiver are connected and the movable terminal and the fixed terminal are brought into contact.

Further, the contact plate is fixed to a sliding rod made of an insulator, and the sliding rod separates the movable terminal and the fixed terminal by a spring.

[0013] A curved portion is provided on one or both of the fixed terminal and the movable terminal.

Further, the sliding rod is provided with a guide portion guided by the side wall of the base.

In addition, the tip of the sliding rod projects outward from the side wall of the base.

[0029]

As described above, according to the present invention, when a normal plug is not inserted into an outlet, terminals of different polarity facing outward are in a double-cut state. No electric shock when plugged in. Also, there is no need to provide a cover or an opening / closing plate on the front side of the outlet, and the insertion of the insertion blade is smooth, and the contact with the blade receiver is ensured.

Since the sliding rod is made of an insulator, the movement is smooth, the contacts of different polarities can be insulated, and the plug is pulled out by a spring to forcibly separate the movable terminal from the fixed terminal. Later, the movable terminal always becomes the non-charged part.

Further, the bending portion protects the terminals by preventing an impact applied to each terminal portion when the plug is inserted.

Further, the guide portion provided on the sliding rod can stably move the sliding rod, and can prevent the insertion blade from being tilted or defectively inserted (poor connection) when the plug is inserted.

In addition, since the tip of the sliding rod protrudes outside the side wall of the base, the sliding rod automatically moves with the insertion of the plug, and the plug has no special shape. No mechanism or mechanism is required.
