Abstract

PURPOSE:To improve wiring work efficiency and to realize uniform distribution of tightening force of a sealing rubber by making a conical body for giving a depressing force to a cover screw-engage with a main body. CONSTITUTION:Fixed shafts 6 are provided on both sides of a main body 1. A loose hole 5 is formed in a form ascending toward the right on either side of one end of the cover 3. A tapered portion 7a sloped and projecting downward is formed on the end surface of a sliding part 7 secured to the other end of the cover 3. A tapered portion 8a of a conical body 8 engages with the tapered portion 7a. When a screw 9 is tightened, the conical body lowers, the tapered portion 7a is pressed, the cover 3 gradually lowers toward the main body 1 to strongly press a sealing rubber 4 and to exert a uniform tightening force, and the cover 3 is secured to the main body 1. When the screw 9 is loosened on the other hand, the engagement between the tapered portion 7a and the tapered portion 8a is gradually lost, the cover 3 rotates about the fixed shaft 6, and the cover can be opened.
