Technical field
The utility model is related to cable safety box technical field, and specially a kind of totally enclosed type cable connector waterproof fireproofing is prevented
Quick-fried safety box.
Background technology
The 18 great anti-accident measures of power network (revised edition) 13.2.1.5 of State Grid Corporation of China in 2011 prevent cable fire
The outermost layer of the non-direct-burried cable connector of calamity should coat fire proofing, oil-filled cable joint and the joint for laying intensive midium voltage cable
Closed using fire resisting anti-explosion groove box.13.2.2.1 the in-service joint of cable close quarters should install fire prevention channel box additional or take other to prevent
Fiery quarantine measures.
After cable laying is good, in order to become a continuous circuit, each section of line must be connected as an entirety, these
Tie point is known as cable connector.Because currently the majority cable is embedded in underground, working environment is poor, and cable connector makes for a long time
Sparking, short circuit are easily produced because of aging in or even is exploded, the heavy losses of economy is caused or even threatens personal life
Life safety.Due to current China cable tunnel limited amount, the number of cables in each cable tunnel is more, when a cable rises
It is hot it is fried after, other cables will be lighted, trigger subsequent explosion, cable tunnel inner cable damage is caused.In order to prevent cable from connecing
Rear trigger on fire occurs at head armored cassette is used at second accident, cable connector.It is on fire in order to prevent from occurring at cable connector
Constantly burning sets off an explosion, it is necessary to ensure the sealing property of armored cassette afterwards, so when on fire after, due to amount of oxygen it is limited and can not
Sustained combustion, can avoid blast as far as possible.
Seal between the connect band of existing armored cassette uses band mostly, due to connecing for band and connect band
Contacting surface product is big, it is impossible to ensure that band and connect band are fitted completely, poor sealing performance.
Utility model content
The purpose of this utility model is to provide a kind of totally enclosed type cable connector waterproof fireproofing anti-explosion safety box, to solve
The existing cable joint explosion-proof box proposed in above-mentioned background technology is big due to band and connect band contact area, it is impossible to ensure
Band and connect band are fitted completely, the problem of poor sealing performance.
To achieve the above object, the utility model provides following technical scheme：A kind of totally enclosed type cable connector waterproof is prevented
Fiery anti-explosion safety box, including it is seal groove, shell, bolt hole, inner casing, cable, silicone rubber O-ring, constriction, explosion-proof fiber, anti-
Chamotte, pressure relief vent and reinforcement, the shell are provided with the inner side for being located at seal groove on seal groove, the shell provided with bolt
Hole, the inward at both ends of the shell is tightened up to form constriction, and the inside of the constriction is provided with silicone rubber O-ring, the inner casing
Two ends be connected with cable, the outside of the inner casing is filled with fire-proof mud, and the top of the shell is provided with pressure relief vent, described outer
The outside of shell and constriction is equipped with reinforcement.
It is preferred that, the seal groove is provided with the sealing strip being engaged with U-shape structure in U-shape structure, and seal groove.
It is preferred that, the pressure relief vent is provided with two altogether.
It is preferred that, the outer surface of the shell is coated with annular-oxygen and rich zinc antiseptic dope.
It is preferred that, the connector exterior that the inner casing is connected with cable is wound with explosion-proof fiber.
Compared with prior art, the beneficial effects of the utility model are：The totally enclosed type cable connector waterproof fireproofing is explosion-proof
Safety box is opened up in the edge of shell provided with the sealing strip being engaged with U-shape structure in U-shaped seal groove, and seal groove, is reduced
The contact area of sealing strip and shell, makes the power that shell applies to sealing strip more concentrate, sealing effectiveness more preferably, shell and tight
The outside in contracting portion is equipped with reinforcement, applies tightening force to shell, makes the combination of lower casing even closer, and increase shell
Structural strength, when occurring explosion time, reduces the impulsive force to surrounding objects, and shell can be made to produce less fragment, prevents brokenly
Bad surrounding objects, the connector exterior that inner casing is connected with cable is wound with explosion-proof fiber, strengthens filling out in the sealing of inner casing, inner casing
The fire-proof mud filled makes the safety box have good fire prevention, water resistance.
