<p>A cable gland includes a nut (1), a waterproof ring (4), a tightening screw cap (5), and a tubular body (3) with external thread. A clamping end of the body (3) is provided with clamping claws spaced by a gap and extending in an axial direction of the body (3). A fixing protrusion protruding outwards is provided on an outer circumferential surface of the body (3), and the nut (1) is fitted with a fixed end of the body (3). A locating protrusion is provided on an inner side of the clamping claws. A limiting groove being open towards the locating protrusion is provided on an inner wall of the body (3). A locating groove fitted with the locating protrusion is provided at one end of the waterproof ring (4), and the other end of the waterproof ring (4) is inserted into the limiting groove. The tightening screw cap (5) is tightly screwed to the clamping end of the body (3). The cable gland prevents the waterproof ring (4) from being pushed out by cables, and the waterproof ring (4) may not easily be deformed, thereby avoiding a clearance from being generated between the waterproof ring (4) and the body (3), improving the sealing performance between the waterproof ring (4) and the body (3), preventing outside dust, moisture or the like from entering into the cabinet, and improving the stable performance of electrical components in the cabinet.</p> |
