Abstract

The invention belongs to the technical field of cable construction, and particularly relates to an anti-explosion cable lead-in device. The problems of unreasonable design and the like in the prior art are solved. The anti-explosion cable lead-in device comprises a straight-through device and a compression nut, an inner thread is arranged on the inner wall of one end of the straight-through device, one end of the compression nut is inserted into the straight-through device and is in threaded connection with the inner thread, a gasket, a blocking piece and a rubber ring which are sequentially arranged from one end of the compression nut to the other end of the straight-through device are arranged in the straight-through device, and the end, away from the compression nut, of the rubber ringis flush with the corresponding end of the straight-through device. The anti-explosion cable lead-in device is simple in structure and can prevent damage.

Description

technical field [0001] The invention belongs to the technical field of cable construction design, and in particular relates to an explosion-proof cable lead-in device. Background technique [0002] Most of the mine explosion-proof electrical equipment currently produced adopts the pressure plate type cable lead-in device to connect the pressure plate to the base with screws, and use the screws to adjust the pressing force of the pressure plate to compress the sealing ring to seal the cable. , the structure of this method is relatively complicated, and at the same time, it is easy to cause damage to the cable. [0003] For example, a Chinese patent discloses an explosion-proof cable entry device, application number 201320672376.8, which includes: a compression nut, which has a first end connected to a steel pipe for routing and a second end connected to the body of the lead-in device, the first The inner cavity body of the second end has an internal thread structure, and the...
