<p><P>PROBLEM TO BE SOLVED: To improve anchorage strength to a lead-in/branch terminal box and electrical connection retentivity in a short circuit and grounding instrument installed in the lead-in/branch terminal box. <P>SOLUTION: In the short circuit and grounding instrument 1 installed in the lead-in/branch terminal box 2, a high-voltage connection terminal 7 connected to an electric path on the power supplying side and a low-voltage connection terminal 6 connected to an electric path on the power receiving side are provided within a hollow body 3, and a lid 4 is provided and mounted so as to open and close an opening section of the body 3. The instrument 1 includes: hollow frames 15, 16; fixing means 25, 39 for enabling the frames 15, 16 to be mounted to the body 3 instead of the lid 4; a contact section 18 provided within the frames 15, 16, having the conductivity, and contacting the low-voltage connection terminal 6; and a grounding cable 23 electrically contacted to the contact section 18 and extended to the outside of the frames 15, 16. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
