Embodiment
Below in conjunction with accompanying drawing, invention is described further.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: a kind of six logical cascade quick cable introducing devices; comprise communicating joint 2, described communicating joint 2 is that cable is imported joint inside, protects the cable of whole connector exterior; by blast space boundary inside communicating joint, the harm to outside can be reduced at explosion time.Be provided with rubber ring 6 in communicating joint 2 inside, described rubber ring 6 has fastening effect to the cable connected, and can prevent foreign matter and water and explosibility gas from entering joint inside; Rubber ring 6 has three holes, wherein has two apertures and a macropore, and the rubber bar 7 of corresponding size is installed in three holes, when deployed, rubber bar 7 is extracted, insert cable; Macropore in three holes is used as the connection of leader cable, namely passes into the main line of joint, and it is powered for equipment cable wiring, and two apertures in three macropores are as the connection of external equipment cable.In described rubber ring 6 one end, steel closure plate II 5 is installed, described steel closure plate II 5 has two holes; Be close to described steel closure plate II 5 and have the steel closure plate I 4 be arranged in communicating joint 2, described steel closure plate I 4 has a hole; Two steel closure plates with holes can rotate in communicating joint 2, and can adjust the aperture position in different hole on two closure plates according to the number of cables entered in joint, thus realize connector exterior and joint inside separately; Described steel closure plate I 4 is the circular slab that two shapes are identical with steel closure plate II 5.Be provided with steel gasket 3 in described steel closure plate I 4 side, steel gasket 3 is connected with and can extrudes and fastening clamp nut 1 described rubber ring 6; Because described communicating joint 2 and described clamp nut 2 screw coordinate, when clamp nut 2 is in rotary course, the wearing and tearing of rubber ring 6 effectively can be prevented by steel gasket 3.Draw cascade electric wire 9 by the snap joint of upper level, be connected in next stage joint, realize powering to next stage joint, reach the object of cascade, all the other four electrical apparatus interstar connections 10 are connected to external electric equipment 8, thus reach the object of cascade.
Concrete use procedure: when not needing access cable, be all inserted with the rubber bar 7 of corresponding size in three holes on rubber ring 6; When needs access cable, take away the rubber bar 7 in described rubber ring 6 three holes, cable is introduced, and rubber ring 6 is placed in communicating joint 2, install two steel closure plates in rubber ring 6 one end.When two steel closure plates do not need cable to access, steel closure plate I 4 is rotated to an angle, make steel closure plate I 4 hole and described steel closure plate II 5 on hole stagger, two holes realized on steel closure plate II 5 are completely closed; When a hole in two holes on described steel closure plate II 5 needs access cable, rotate steel closure plate I 4, make a hole centering in the hole on steel closure plate I 4 and three holes on steel closure plate II 5, and by its corresponding access cable aperture; When two holes on described steel closure plate II 5 need access cable, steel closure plate I 4 is taken away, only leaves steel closure plate II 5, and by the hole centering of two in steel closure plate II 5 on two holes on described rubber ring 6; When needs access three cables, steel closure plate I 4 and steel closure plate II 5 are all taken away, realizes the access of three cables.After connecting cable, in communicating joint 2, put into steel gasket 3, and clamp nut 1 is rotated, realize the compression of rubber ring 6 and fastening.
