Technical Field
The utility model belongs to the explosion-proof cable field, concretely relates to locking explosion-proof type cable entry device.
Background
The power supply introduction or the electrical output of the explosion-proof electrical equipment should be generally performed through a cable introduction device which is structurally divided into two types: sealing ring type and pouring type; the sealing ring type is divided into a pressing nut type and a pressing disc type. The explosion-proof principle of the compression nut type lead-in device is as follows: in this introduction, the sealing ring is made of vulcanized rubber, which is a compression-deformable material that changes its shape but does not change its volume under the action of an external force. Therefore, the sealing ring is deformed under the action of the compression nut to seal the gap between the sealing ring and the communication joint and between the sealing ring and the cable, so that combustible gas can be prevented from entering a wiring cavity of electrical equipment or an equipment shell.
Because the rubber material has certain elasticity, after the compression nut type lead-in device is used for a little long time, the communicating joint with the nut can be gradually unscrewed, so that a small gap exists between the sealing ring and the cable, and the explosion-proof performance of the cable lead-in device is lost.
