A kind of moisture-proof terminal box, including chamber door, casing, the bottom surface of casing are equipped with damp-proof layer, three sides, one of casing
Individual top surface is provided with thermal insulation layer, and the bottom setting of casing is fluted, and osculum, the chamber door 1 and case are offered on the groove
Body joint place installs sealing joint strip additional.
Silica-gel desiccant poly-bag is disposed with the casing, silica-gel desiccant poly-bag is open or boxes out, for the moisture absorption.
The silica-gel desiccant poly-bag is transparent glue bag, and transparent glue bag contains silica-gel desiccant, and silica-gel desiccant absorption is empty
Air water point, gradually change colour during drier water content increase, pass through the agent discoloration that sees drying, judge casing damp degree.
The cabinet arrangement having heaters, heater are arranged in the less one side of terminal block, avoid heater line and end
Son row's contact short circuit.
The bottom half sets a rise seat, is easy to divulge information, eliminates stack effect.
The damp-proof layer is the inorganic putty of neutral water soluble.So, not by maintenance power box, terminal when the damp-proof layer is laid
Shape influences inside case, can be made into arbitrary shape, moreover, anatomic shape after drying, easy cleaning.
The chamber door bottom groove makes a call to 3 osculums, and position is chosen at left end in groove, middle part, right-hand member.
The thermal insulation layer includes multiple insulating block units, is provided with cavity in the insulating block unit, adjacent two
The expanded and vitrified small ball for being mixed with adhesive is provided with space between insulating block unit.
A kind of moisture-proof terminal box of the utility model, can smoothly drain terminal chamber door groove ponding, can effectively prevent because
The safe operation of electric network accident that moist or bad weather causes terminal chamber door ponding and induced.Meanwhile the utility model has knot
Structure is simple, low cost, service life length, meets a variety of actual demands.
Brief description of the drawings
Fig. 1 is moisture-proof terminal box structural representation of the present utility model.
Embodiment
As shown in figure 1, a kind of moisture-proof terminal box, including chamber door 1, casing 2, the bottom surface 2.1 of casing 2 are equipped with damp-proof layer 3,
Three sides of casing 2, a top surface are provided with thermal insulation layer 4, and the bottom of casing 2 sets fluted 5, opened up on the groove 5
There is osculum 6, the chamber door 1 installs sealing joint strip 7 additional with the joint place of casing 2.
Silica-gel desiccant poly-bag 8 is disposed with the casing 2, silica-gel desiccant poly-bag 8 is open or boxes out, for the moisture absorption.
Silica-gel desiccant poly-bag 8 is placed in the corner of bottom surface 2.1 of casing 2；Or it is bonded on three sides of casing 2.
The silica-gel desiccant poly-bag 8 is transparent glue bag, and transparent glue bag contains silica-gel desiccant, and silica-gel desiccant absorption is empty
Air water point, gradually change colour during drier water content increase, pass through the agent discoloration that sees drying, judge the damp degree of casing 2.
The casing 2 arranges having heaters, and heater is arranged in the less one side of terminal block, avoid heater line with
Terminal block contact short circuit.
The bottom of casing 2 sets a rise seat, is easy to divulge information, eliminates stack effect, can both avoid in cable duct
Moisture be directly entered terminal box, cable duct and extraneous air exchange can be increased again, exclude moisture in time.
The damp-proof layer 3 is the inorganic putty of neutral water soluble.So, not by maintenance power box, end when the damp-proof layer 3 is laid
Shape influences inside sub- case, can be made into arbitrary shape, moreover, anatomic shape after drying, easy cleaning.
The bottom groove of chamber door 1 makes a call to 3 osculums 6, and position is chosen at left end, middle part, right-hand member in groove 5.Bore draining
The instrument in hole 6 is electric drill, direction by groove from inside to outside.A diameter of 8 mm of osculum 6, specific size can be according to the width of groove 5
Spend suitably modified.After opening osculum 6, the burr of surrounding is polished off with file, prevents the burr at the edge of osculum 6 after perforate from existing
When switching chamber door, chamber door sealing joint strip is scratched.When terminal box internal-external temperature difference is to certain value, moisture, moisture can be in chamber doors 1 in case
Upper generation condensation, ponding, condensation, ponding are converged at 3 osculums 6 of bottom groove and discharged, so as to keep being done in terminal box
It is dry.
The thermal insulation layer 4 includes multiple insulating block units, is provided with cavity in the insulating block unit, adjacent two
The expanded and vitrified small ball for being mixed with adhesive is provided with space between insulating block unit.Thermal insulation layer be designed as several every
Hot plate module unit, it is easy to splicing to assemble.
The insulating block unit should be designed according to the actual size of terminal box, cut, punched in advance, in order to pacify
On each face in casing.Thermal insulation layer 4 is easily obtained using the materials such as stainless steel materials, material, is simple to manufacture.Every
Hot material is expanded and vitrified small ball, and expanded and vitrified small ball is a kind of environmental protection inorganic light heat-insulating material, meets national GB8623-
The non-ignitable standard of 2006A1 levels, there is light, insulation, adiabatic, fire prevention, intensity height, long lifespan.
The silica-gel desiccant poly-bag 8 is transparent glue bag, and transparent glue bag contains silica-gel desiccant, silica-gel desiccant mainly into
It is divided into silica, is a kind of high activity sorbing material.Air moisture is adsorbed by silica-gel desiccant, during drier water content increase
Gradually discoloration.By observing silica-gel desiccant discoloration, terminal box damp degree is judged.When drier adsorption saturation, take
Go out drier, be reentered into after dewater treatment, envelope stores again.Silica-gel desiccant discoloration is inspected periodically, when drying
It is blueness, becomes pink after the moisture absorption.
