Description
Technical field
The present invention relates to electrical power distribution electro-technical field, a kind of flexible explosion-proof connector box and its production method are particularly related to.
Background technology
Power distribution network build, repairing during, be commonly applied to cable and cable intermediate joint, due to built environment by
Limit, more cables are total to ditch situation generally existing.And cable is when being total to ditch, it is huge due to will produce when a certain cable intermediate joint failure
Impact force, and environment temperature is caused to increase.On the other hand, because there may be imflammable gas in cable duct, and it is general
In the case of the insulating materials of cable body be also combustible, therefore a cable and junction malfunction also easily generates open fire, leads to it
His total ditch cable is involved, and causes to have a power failure on a large scale, loss is inestimable.Chinese patent 201420817343.2 discloses
A kind of cable intermediate joint flexible explosion-proof box, including:Flexible bellow and two explosion-proof end sockets for being located at its both ends, each
The explosion-proof end socket is made of a upper shield and a lower shield;Lead to respectively between flexible bellow and two explosion-proof end sockets
Flange is crossed to be fixedly connected with fastening screw;Filling hole is offered on the explosion-proof end socket;Filled with protection material in the armored cassette
Material.Although the patent application realizes flexible connected, but its there are still problems with:1, its is complicated for operation, " first by centre
Flexible bellow 3 penetrates 8 side of cable, the making of cable intermediate joint is then carried out, after making, by flexible bellow 3
It is placed on cable intermediate joint position;The upper shield of explosion-proof end socket 1 and lower shield 2 are fastened again, and passed through with flexible bellow 3
Flange 4 is fixedly connected with fastening screw 5;Grail is filled into armored cassette by the filling hole 6 on explosion-proof end socket later
Or the protective materials such as dry powder fire retardant 9, then clogged with stopple 7 by hole 6 is filled." step is more, materials are complicated, in particular by
Flexible bellow need to penetrate cable, operated in narrow space limited;2, it makes there is still a need for using filling mode explosion-proof
Clad outside at cable connector is thicker, when connector is abnormal situation, can not effectively pass out connector and abnormal shape occurs
The signal of condition;3, still doped with metallic framework in its flexible bellow, connecting mode, can not there is still a need for conductive attachment part is used
It avoids that closed loop conductive path can be formed, is formed by closed loop conductive path under the influence of the magnetic field that energization cable generates, understands in it
Portion forms circulation, and fever, there are security risks.4, its structural material is the rigid material such as steel, easily to the epidermis of peripheral cable
It is formed to squeeze and even be damaged, and the insulation performance of flexible bellow is unsatisfactory.

Connector box insulation when in use and waterproof effect.In the present embodiment, the upper box cover 1 and lower casing 4 use vulcanized rubber one
Method is made of body formed:Rubber raw materials progress raw rubber is plasticated according to a conventional method, compounding agent is added to be kneaded, park, heat refining, sulphur
Change, deburring, before the vulcanisation step is implemented, the steel plate be embedded in inside the sealing shirt rim 5 of rubber stocks, one into
Enter in vulcanizing equipment and is vulcanized.As stated above prepared upper box cover 1 and lower casing 4 can acid-alkali-corrosive-resisting, have good
Corrosion Protection.
In addition, in specific setting, as shown in Fig. 2, having the multiple through-holes arranged along its length on upper box cover 1
11;Temperature-sensitive paster is pasted on the through-hole 11.In specific setting, the multiple through-hole 11 is located at the upper box cover 1 and heaves
Arcuate structure on.So that warming paster 3 is able to detect that the temperature change of 7 joint of cable, can effectively prevent
Occur on fire.So that the present invention is had temperature function in monitor box, can in time show security risk existing for 7 connector of cable
Come, to handle or to overhaul.
In the present embodiment, which has both pressure relief vent function, when normal pressure, temperature detection paper
Pressure relief vent and temperature detection hole are sealed, and overtemperature situation is shown.Instantaneous event occurs inside flexible explosion-proof connector box
When barrier, pressure is washed open from weaker temperature detection paper sealing place of box body, is played the role of pressure relief vent, is avoided the hair of explosion accident
It is raw.In the present embodiment, 70-100 DEG C of temperature monitoring can be achieved in the present invention.Temperature anomaly situation in box is shown, into
And can release, avoid the generation of explosion accident.
In specific connection, as shown in Figure 1, upper box cover 1 and the lower casing 4 are connected by multiple strength bands 2.And it is more
A strength band 2 binds the both ends and centre position of upper box cover 1 and lower casing 4, ensures have between upper box cover 1 and lower casing 4
Good sealing.
It can be seen from the above description that the present invention closes button mode using upper box cover and lower casing along cable axis, it is not necessarily to
Be inserted in any part from cable socket, in appropriate cable ditch the narrow operation of installation space need, and box body have both it is flexible and just
The needs of support are spent, existing certain deformation can meet the needs of insulation and rigid support to adapt to the needs of connector installation.On
Box cover and lower casing are structure as a whole, easy for installation, easy to operate.The present invention has flexibility, fire prevention, arc extinguishing, pressure release, fire-retardant
The features such as, it is easily installed, more for functions such as temperature monitorings, is conducive to usual inspection, is suitable for different installation environments, so as to have
The isolation of effect ground does not damage other electricity in same tunnel when being protected cable connector electrical hazard occur by protection cable connector
Cable.
