본 발명은 일반가정이나 건물의 벽에 매설되는 전원공급용 콘센트가 안정된 접지효과를 얻을 수 있도록 한 콘센트의 접지구조에 관한 것으로, 전자기기 또는 전기기기 등의 각종 정밀기기 제품에 전원을 공급하기 위한 전원코드의 단부에 설치된 플러그를 콘센트에 꽂아서 사용할 때 플러그의 접속단자 중간부분에 돌출되게끔 설치된 접지단자와 대응하여 긴밀하고 견고하게 접속되어 안정된 접지효과를 얻도록 벽에 매설되는 콘센트몸체의 상측부에 덮혀지는 커버체의 접속단자 삽입구멍의 중간부분에 접지부를 형성하되, 상기 커버체의 접속단자 삽입구멍의 중간부분에 플러그의 접지단자 삽입용 접지구멍을 형성하고, 그 하측부에는 상기 접지구멍에 대응하는 접지단자부를 돌출되게 형성하며 양단부는 하향 절곡되어 접속부를 일체로 형성한 접지용 접속판을 커버체의 내면부에 밀착되게끔 결합하여서 되는 것이다.The present invention relates to a grounding structure of a power outlet so that a power supply outlet embedded in a wall of a general home or a building can obtain a stable grounding effect, and to supply power to various precision equipment products such as electronic devices or electrical devices. The upper part of the outlet body buried in the wall to be connected firmly and firmly to obtain a stable grounding effect in response to the earthing terminal installed to protrude in the middle of the plug connection terminal when the plug installed at the end of the power cord is plugged into the outlet. A grounding portion is formed in the middle portion of the connection terminal insertion hole of the cover body which is covered by the cover body, and a grounding hole for insertion of the grounding terminal of the plug is formed in the middle portion of the connection terminal insertion hole of the cover body, and the grounding hole is formed in the lower portion thereof. A ground terminal portion protruding from each other is formed to protrude, and both ends are bent downward to form a contact portion integrally formed. The connecting plate for paper is to be bonded to be in close contact with the inner surface of the cover body.

종래의 콘센트는 일반적으로 전원을 배선함에 있어서 연결 접속을 하기 위하여 별개의 물품으로 구성된 통상의 콘센트와 벽면에 매설되게 설치된 콘센트로 구분할 수 있는 것이며, 특히 110V용 콘센트의 경우에는 상기 어떠한 종류의 것이던간에 접지를 위한 접지부가 전혀 형성되지 않았던 것이다.Conventional outlets generally can be divided into ordinary outlets composed of separate items and outlets installed on the wall for connection connection in power supply, especially for 110V outlets of any kind There was no grounding part for grounding at all.

그러나, 220V용 콘센트의 경우에는 110V에 비해 승압된 전압이 흐르기 때문에 감전사고와 같은 안전사고를 방지하고져 대부분의 제품이 접지부를 형성하였다. 이는 첨부도면 제 5 도에 도시된 바와 같이 콘센트(1)의 표면부에 형성되는 플러그의 접속단자 삽입구멍(2)의 일측부, 즉 통상적으로 원형을 이루는 220V전용의 플러그 외주연이 닿는 부분에 접지구멍(3)을 형성하고 그 하부에는 접지판(4)을 연결 구성하였던 것으로, 이러한 콘센트는 콘센트(1)의 접지구멍(3)에 대응하게끔 형성된 플러그의 접지단자 한쌍의 접속단자와 직교하는 외주연부에 위치하게끔 구성되므로서, 상기 콘센트에 플러그를 접속시키기 위하여는 큰 삽입력으로 꽉 끼워지도록 하여야만 긴밀하고 견고한 접속상태와 그에 따른 안정된 접지효과를 얻을 수 있었던 것이다.However, in the case of a 220V outlet, a voltage boosted compared to 110V prevents a safety accident such as an electric shock, thus forming a ground part of most products. As shown in FIG. 5 of the accompanying drawings, it is connected to one side of the connection terminal insertion hole 2 of the plug formed in the surface portion of the outlet 1, that is, a portion where the plug outer circumference dedicated for 220V, which is generally circular, touches. The ground hole 3 is formed and the ground plate 4 is connected to the lower portion of the ground hole 3. The outlet is orthogonal to a pair of connection terminals of the ground terminal of the plug formed to correspond to the ground hole 3 of the outlet 1. Since it is configured to be located at the outer circumferential edge, in order to connect the plug to the outlet, a tight and secure connection state and a stable grounding effect can be obtained only by tightly inserting with a large insertion force.

이러한 콘센트에 접속되는 플러그는 상당한 하중이 작용하기 때문에 플러그와 콘센트가 쉽게 손상되거나 파손되는 경우가 허다할 뿐만 아니라, 사용상의 불편함과 접속부분의 긴밀하고 안정된 접속상태를 얻지 못하는 경우가 많았던 것이다.Since the plugs connected to such outlets have a significant load, they are not only easily damaged or broken, but also many inconveniences of use and inability to obtain a close and stable connection state of the connection parts have been obtained.

본 발명은 상기와 같은 종래의 제반 문제점을 해결 보완하여서 사용상의 편리함과, 플러그와 접속시킬 때 항상 긴밀하고 견고하게 접속되어 안정된 접지효과를 얻을 수 있는 콘센트의 접지구조를 제공하고져 함에 발명의 목적이 있는 것이다.The object of the present invention is to provide a grounding structure of an outlet that can solve the above-mentioned conventional problems and provide convenience in use and a stable grounding effect by always being tightly and firmly connected when connected to a plug. It is.
