Abstract

<P>PROBLEM TO BE SOLVED: To provide a receptacle safety circuit device for achieving a longer service life by improving the safety of a safety receptacle. <P>SOLUTION: The receptacle safety circuit device includes, mainly, one receptacle body, a conduction circuit, and an access circuit. On the receptacle body, clamping components are installed for clamping both insertion pieces of an electric product. On the receptacle body, a power cord is also separately installed for energizing the access circuit. Additionally, in the conduction circuit, at least normally-open contacts between both clamping components differently supported are formed between both sides of the clamping components. In this design, when the insertion piece of a plug is inserted into the clamping component, the access circuit controls the energization of the normally-open contact in the conduction circuit to form a normally-closed contact. This avoids the event that the foreign matters enters at the same time to be inserted into both clamping components, leading to energization, to improve the safety of the receptacle when used. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a safety circuit device for an outlet, and enhances safety during use.

  Due to the widespread use of home appliances, every day in daily life comes in contact with electrical products such as televisions, personal computers, washing machines, and table lamps. In addition, these home appliances can be powered by plugging them into a wall outlet or an extension cord outlet. In general outlets, the insertion holes for inserting plugs of electrical products are open, so if an infant inserts foreign objects into the insertion holes, there is often a risk of electric shock. In order to improve the above-mentioned drawbacks, it is well known to cover the outlet hole of the outlet. However, if the lid is used, the convenience of use is affected. Therefore, it is the mainstream to improve the current conductive circuit inside the outlet.

  In the current safety outlet structure, as shown in FIGS. 1 and 2, a fixed base unit constituted by a pair of both high fixed base 11 and both low fixed bases is installed at the bottom of the outlet 1. Among them, the two high fixed bases 11 are respectively installed on both sides of the low fixed base 12, and the open tub 111 is respectively designed thereon, and the sliding plate 2 having the corresponding sliding holes 21 is installed therebetween. Further, the two low fixing bases 12 between the two high fixing bases 11 form a side-by-side state relative to the sliding plate 2. A semi-circular tank 121 in which the pin columns 3 are installed is designed at the uppermost ends of the two low-fixing bases 12, and both sliding plates 2 are positioned and slid left and right. Separately, the long and short spring pieces 4 and 5 of both sets are fixed and movable, respectively, are installed inside the outlet 1 and are opposed to the position of the base hole 13, and the sliding plate 2 and the pin pillar 3 are high and low fixed bases 11, When fixed at 12, the sliding holes 21 of both sliding plates 2 are slid left and right relative to the pin column 3. Thus, when a foreign object is inserted into the base hole 13 on one side, it is not conductive, thereby preventing an electric shock.

The above-mentioned known safety outlet theoretically has a function to prevent electric shock, but the safety function does not work correctly in actual operation. In other words, this known structure has a risk of electric shock during use. At the same time, this structure is poorly designed and has the following problems in use.
1. In the known safety outlet, the sliding plate 2 slides to the left and right to push the short spring piece 5 so that the short spring piece 5 and the long spring piece 4 come into contact with each other and the power supply passes therethrough. However, when a foreign object is inserted only into the base hole 13 on one side, the base hole 13 on that side cannot be energized, but the base hole 13 on the other side is energized. If an infant inserts a foreign object having both holding pieces, such as a similar metal clip, into the pedestal hole 13 at the same time, or inserts one foreign object with both hands, both the sliding plates 2 are pushed to operate the short spring pieces 5 to improperly energize May cause electric shock. Therefore, the certain safety level is insufficient.
2. Furthermore, the above-described known structure achieves the purpose of energization by the sliding function of the sliding plate 2. These sliding plates 2 are provided with pin columns 3, but when the sliding plate 2 slides to the left and right in the lateral direction, friction occurs with the pin columns 3, and something is clogged when the plug is inserted. It is easy to feel and affects the smoothness of insertion. At the same time, if the friction is greatly damaged, the contact of the power supply becomes worse, so this structure is not good.

  In order to solve these problems, Patent Document 1 solves the above-mentioned known drawbacks and inconveniences. The purpose is to respond.

  The present inventor has made a thorough study on safety problems with the above-mentioned outlets, and has been actively seeking a way to solve them, and has succeeded in developing a kind of outlet safety circuit device through long-term efforts. Enhance safety and extend service life.
