Abstract
An energy discharge type explosion-proof box for the central connector of a cable comprises a housing made from stainless steel synthetic material. The whole housing is of a cylindrical shape and is integrally formed by two semi-cylindrical housings one time in a non-soldering manner. An energy discharge hole is arranged on the side surface of the housing. A sealing plug is disposed on the energy discharge hole. If short circuit occurs and the central connector of a cable is on fire, a fireproof arc resistance band provides an arc resistance effect without external combustion. During mounting, the energy discharge hole is adjusted so as to direct toward a safety direction. After the mounting is finished, energy discharge is carried out for the sealing plug via silicone rubber so that the energy discharge hole is sealed. Once the central connector of a cable explodes, the energy discharge sealing plug can be rapidly opened for energy discharge, and the housing can help to prevent the explosion of the central connector of a cable from damaging other cables or channels.
Description
Technical field
The utility model relates to a kind of cable intermediate joint armored cassette.
Background technology
Well-known anti-explosion product housing main material iron plate or steel plate, and the product body must reach sealing; So-called explosion-proof being meant under hermetic situation just can be played explosion-proof.Hermetically sealed because of oxygen, air are arranged because if cable does not have when producing spark, thus just can produce fire, and then blast.If therefore anti-explosion product fails to accomplish must not reach explosion-proof effect under the hermetic situation.
And we select for use the cable armored cassette will arrive expected effect, and reason can reduce five kinds of situation: 1. electric cable accessories quality problems; 2. cable quality problem (as when the payout, cable sheath damage and water inflow or cable are put back sealing cap useless well it is sealed, and cable in wet condition); 3. electric cable accessories mounting process problem; 4. running environment problem; 5. overload operation, the too high problems of excessive heat of temperature of cable junction.
Our cable mid head majority is in cable trough or cable shaft, to move; Influenced by running environment so a lot of accidents take place, account for a greater part of factor at least, in water, move because of often steeping; Make moist; Advance situation such as air, take place then that cable end punctures, spontaneous combustion, more serious after blast, also wound other cable blown up even burnt.Move in water if the armored cassette of usefulness is the hermetic frequent bubble of cable mid head of just can avoiding, make moist, advance situation such as air, lower the probability that has an accident, avoid when having an accident, dropping to loss minimum.
The utility model content
The purpose of the utility model provides a kind of cable intermediate joint armored cassette, addresses the above problem.
The purpose of the utility model is to realize through following technical scheme:
Rush down ability formula cable intermediate joint armored cassette; Comprise the housing of making by the corrosion resistant plate synthetic material; Housing integral body is not had by two semicolumn housing overall times and is welded into the cylindrical of shape, is provided with in the side of housing that rush down can the hole, and is rushing down and can on the hole sealing plug be installed.
After housing installs cable intermediate joint, fire prevention arc resistant band is earlier wrapped on the cable intermediate joint that has installed, be seated in the fire protection flame retarding expanding material in the transparent armored cassette shell; Transparent armored cassette product then is installed; The affirmation screw is all gone up (revolving) and is tightly afterwards evenly stamped the cable fire-proof fluid sealant around the both sides and the two ends of transparent armored cassette, reinforces the sealing of product, when being short-circuited; When the cable intermediate joint place is on fire, fire prevention arc resistant band will play the effect that arc resistant makes not external combustion of fire; Regulate during installation rush down can the hole make its aim at secure side to; Installing back use silicon rubber rushes down and can will rush down and can seal in the hole by sealing plug; When cable intermediate joint is blasted; Rush down can sealing plug can open rapidly rush down can, housing can prevent the destruction of cable intermediate joint blast to other cables or other circuit.
Two semicolumn housings of housing are connected by the recessed end screw of hexagonal in explosion-proof; The diameter at the housing two ends formation tightening mouth that diminishes, and form one section small size at the tightening mouth place cylindrical, the inside of tightening mouth is equipped with groove type sealing ring waterproof sealing attachment design; Adopt the manufacturing of high quality silicon elastomeric material; Inner walls is seated in the fire protection flame retarding expanding material in the transparent armored cassette shell with the fire protection flame retarding thermal insulation layer, and housing outer surface is coated with insulating corrosion uvioresistant lacquer.Flat shape silastic sealing strip is equipped with on the armored cassette both sides, and unique dual groove type sealing ring design is adopted at two ends, the sealing strip disposal integral molding, and sealing ring adopts the squash type structure, and water resistance is splendid.On the housing face of cable intermediate joint armored cassette semicylinder be with the centre neutral point each be provided with one toward both sides rush down can the hole, rush down and can adopt high quality silicon rubber to make by port lid, and rush down and can adopt unique design by port lid.Blast when cable intermediate joint, rush down can seal cover can open rush down can, the naked light that produces that also can prevent to explode of the dilatancy fire-fighting fire retardant in the housing spreads.
After installing cable intermediate joint, on the wrapped cable intermediate joint that has installed of fire prevention arc resistant band elder generation, be seated in the fire protection flame retarding expanding material in the transparent armored cassette shell; The armored cassette product then is installed; The affirmation screw is all gone up (revolving) and is tightly afterwards evenly stamped the cable fire-proof fluid sealant around the both sides and the two ends of armored cassette, reinforces the sealing of product, when being short-circuited; When the cable intermediate joint place is on fire, fire prevention arc resistant band will play the effect that arc resistant makes not external combustion of fire; Regulate during installation rush down can the hole make its aim at secure side to; Installing back use silicon rubber rushes down and can will rush down and can seal in the hole by sealing plug; In case cable intermediate joint is blasted; Rush down can sealing plug can open rapidly rush down can, housing can prevent the destruction of cable intermediate joint blast to other cables or raceway groove.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structure chart of the described cable intermediate joint armored cassette of the utility model embodiment.
Fig. 2 is the partial sectional view that rushes down place, ability hole among Fig. 1.
Embodiment
