PURPOSE:To increase the interval of upper and lower plugs to facilitate the connection of transmission lines by placing the lower most plug seat at a side wall biased downward till the lower part of the plug seat and the upper part of the link element at the lower ridge of a main body are overlapped perspectively. CONSTITUTION:The position of a lowermost plug seat 13 on a side wall is decided to a position where a lower part (a) of a plug seat 13 and an upper part (b) of a link element 21 are overlapped perspectively when viewing from the left side of figure. Then in the case of connecting a transmission line 11c whose one terminal connects to a power supply device to the plug seat 13 of the side wall closer to the power supply device, a terminal 11 fitted to the transmission line 11c is screwed to a thread hole 13a of the plug seat 13. In the case of the work above, even if a transmission line 10c is connected to the upper plug seat by using already a terminal 10, the interval between the plug seat and the plug seat 13 is large. Thus, connecting work is facilitated. |
