Abstract

The utility model discloses a rubber sleeve electric and optical cable double entry used for explosion-proof electric apparatus under the environments with explosive gases and dust. A gland nut (9), a metal gasket (8), a steel baffle (7) and a seal ring (6) are arranged inside an outer communicating joint (5) and are connected with the right end of an outer hood (4) to form an outer entry; the gland nut (9), the metal gasket (8), the steel baffle (7) and the seal ring (6) are arranged inside an inner communicating joint (3) and are connected with a junction box (1) together to form an inner entry; the outer periphery of the left side of the inner communicating joint (3) of the inner entry is provided with a boss (12); and the boss (12) is movably connected with the inner wall of the outer hood (4) to form an explosion-proof structure. According to the utility model, as direct entry way is converted into an indirect entry way, the serviceable range of the rubber sleeve electric and optical cable double entry used for explosion-proof electric apparatus is expanded and condition limitation is broadened.

Description

Explosion-proof electric apparatus is electric with the rubber cover, the dual introducing device of optical cable
Technical field: the utility model relates to a kind of explosion-proof electric apparatus that uses, optical cable dual introducing device electric with the rubber cover in the environment that has damp, dust to exist.
Background technology: under coal mine, exist in the environment of damp, dust with other field, when the cable of explosion-proof electric apparatus adopts direct introducing mode, its inside does not allow to occur spark, electric arc or dangerous temperature when normally moving, and the scope of application is very narrow, and is subjected to the restriction of condition.
The utility model content: the utility model has overcome the drawback that directly introducing mode of former explosion-proof electrical equipment cable exists, and provides the explosion-proof electric apparatus that reliable explosion separation structure is set between a kind of inside and outside introducing device, optical cable dual introducing device electric with the rubber cover.The purpose of this utility model is achieved through the following technical solutions: described clamp nut 9, metal washer 8, steel closure plate 7 and sealing ring 6 install communicating joint 5 inside outside, and and outer cover 4 right-hand members link together and form outer introducing device, clamp nut 9, metal washer 8, steel closure plate 7 and sealing ring 6 devices at interior communicating joint 3 inner and and terminal box 1 link together form in introducing device, the neighboring, interior communicating joint 3 left side of interior introducing device is provided with boss 12, and boss 12 and outer cover 4 inwalls are movably connected to form explosion separation structure.
The beneficial effects of the utility model are: owing to change directly introducing mode into indirect introducing mode, expanded the scope of application, condition restriction is relaxed.
Description of drawings: Fig. 1 is a front view of the present utility model
Fig. 2 is the right view of Fig. 1
Embodiment: embodiment 1: as shown in Figure 1 and Figure 2, described clamp nut 9, metal washer 8, steel closure plate 7 and sealing ring 6 install communicating joint 5 inside outside, and and outer cover 4 right-hand members link together and form outer introducing device, clamp nut 9, metal washer 8, steel closure plate 7 and sealing ring 6 devices at interior communicating joint 3 inner and and terminal box 1 link together form in introducing device, the neighboring, interior communicating joint 3 left side of interior introducing device is provided with boss 12, and boss 12 and outer cover 4 inwalls are movably connected to form explosion separation structure.
Embodiment 2: as shown in Figure 1 and Figure 2, described outer cover 4 left outer ends are provided with fixing feet 10, by being fixed together with bolt 11, outer cover hold-down nut 2 and terminal box 1.
Operation principle of the present utility model is: the outer cover of outer introducing device with interior introducing device cover within it, the boss of interior introducing device is formed explosion separation structure with the inner chamber of outer introducing device outer cover, in the mode of dual introducing, be to introduce structure indirectly with the structural transformation of former direct introducing.Lose when quick-fried at interior introducing device, outer introducing device is the another road guarantee of equipment explosion-proof performance.
