[0025] Please refer to Figure 1-6 The present application provides a technical solution: a quick installation cable explosion-proof joint, which is composed of an explosion-proof shell 1, an insulating rubber body 2, a conductive cylinder 3, two plug-in cylinders 4, two stress cones 5, two stop rings 6, two tail pipes 7, two sealing washers 8, two compression sleeves 9, two nuts 10, and two cables 11 to be connected. The insulating rubber body 2 is fixed inside the explosion-proof shell 1, the conductive cylinder 3 is fixed inside the insulating rubber body 2, the two plug-in cylinders 4 are symmetrically inserted inside the conductive cylinder 3, and watchband contact fingers 43 are arranged between the two plug-in cylinders 4 and the conductive cylinder 3 to prevent poor contact after insertion. The two stress cones 5 are also symmetrically inserted inside the insulating rubber body 2 and located on both sides of the conductive cylinder 3. The end of each stress cone 5 is fixedly connected with a stop ring 6 (the stop ring 6 is made of insulating material). When the plug-in cylinder 4 is inserted into the conductive cylinder 3 and in place, the stop ring 6 abuts against the conductive cylinder 3, and when the two conductive cylinders 3 are in place, an explosion-proof gap 12 is reserved between them. The setting of the explosion-proof gap 12 can avoid direct contact between the ends of the two cables, thereby preventing sparking and even explosion.

In addition, threaded holes 41 are provided on the surfaces of the two plug-in tubes 4, and the cable 11 is fastened by screwing the screws 42 into the inside of the threaded holes 41.

[0027] When using the connector to connect two cables 11, first, both end caps 101 need to be threaded onto both ends of the explosion-proof housing 1, and then the two end caps 101 need to be threaded onto both ends of the explosion-proof housing 1, and then the two end caps 101 need to be threaded onto the two ... Figure 3 For example), put the nut 10, compression sleeve 9, sealing gasket 8, tail pipe 7, stress cone 5 and stop ring 6 and plug-in tube 4 on the outside of the cable 11 in sequence (after the plug-in tube 4 is put on, use the screw 42 and threaded hole 41 to lock it on the cable 11, and then put the strap contact finger 43 on the outside of the plug-in tube 4), and then insert the above-mentioned whole into the conductive tube 3 of the explosion-proof housing 1 at the same time. After being inserted into place, the stop ring 6 and the conductive tube 3 are against each other, and the adjacent ends of the two cables 12 are connected. There will be an explosion-proof gap 12, and then the two tail pipes 7 are fixed to the two end caps 101 by screws, and then the two nuts 10 are tightened onto the tail pipes 7.
