Zusammenfassung: | An electric conduit capable of external measurement of a coupling length according to the present invention may comprise: a pipe main body which is provided such that an electric wire may pass therein, and has the length extended after the end portion and the end portion of another pipe main body adjacent thereto are inserted into both ends of a connecting body; and a coupling length measuring unit which is provided at one end or both ends of the pipe main body to measure the coupling length of the connecting body from the outside. According to the present invention, the coupling length measuring unit is provided at one end or the both ends of the pipe main body, such that, when coupling at the connecting body is performed, the length by which coupling is performed at the both sides of the connecting body may be measured from the outside by means of the distance between the coupling length measuring unit and the end portion of the connecting body, thereby preventing a coupling failure with the connecting body.
개시된 본 발명에 따른 결합길이 외부 측정이 가능한 전선관은, 내부에 전선이 통과하도록 구비되며, 단부와 이와 이웃한 관 본체의 단부가 연결체의 양단에 삽입되면서 길이가 연장되는 관 본체; 및 상기 관 본체의 일단 또는 양단에 상기 연결체의 결합길이를 외부에서 측정이 가능하도록 구비된 결합길이 측정부;를 포함한다. 본 발명에 의하면, 관 본체의 일단 또는 양단에 결합길이 측정부가 구비되어 연결체에 결합시 결합길이 측정부와 연결체의 단부와의 거리를 통해 연결체의 양쪽에 결합된 길이를 외부에서 측정이 가능하므로 연결체와의 결합 불량을 방지 가능한 효과가 있다. |
