Title: Insulated staple
Inventor: KAWAGUCHI TAKEO
IPC: F16B15/00
Filed: 1988-09-29
Abstract: PURPOSE:To stop the coming off of an insulated staple and prevent the driving in too far thereof by bending the upper parts of the staple toward their inside respectively and forming the parts from the bent parts to the tops of both legs slant outward respective. CONSTITUTION:The boundary parts between waist parts 3, 3 and leg parts 1, 1 are formed in parts 2, 2 bent inward respectively. Even if a gap between the top end parts 5 to 5 of the leg parts 1, 1 is formed in nearly same as a gap between the bent parts 2 to 2 after driven in by narrowing the gap between these bent parts 2 to 2, the leg parts 1, 1 are still slant outward respectively. As the gap between holes made on the upper surface where the leg end parts 5 to 5 are driven in is nearly equal to the gap between the bent parts 2, 2 after the completion of driving in, the driving in holes are neither expanded and a body 6 covered by an insulator is nor deformed. Therefore, a covered cable 8 is involved in its safe status and driven in a cable sticking body 9. The leg parts 1, 1 are expandingly driven in while increasing their slants further and as the holes made slantingly act as stopping walls, strong stopping action effect against coming off can be obtained.
