Also, instantly during windscreen wiper wind, some dusts or rainwater enter inside distribution box easily by string holes, influence first device in distribution box
The normal work of part.
Utility model content
The purpose of this utility model is to provide a kind of comprehensive distribution box cable protection curved head type string holes, can effectively solve the problem that
The problem of insulating barrier of cable is destroyed in cable threading process and prevents rainwater or dust from entering distribution box, it is simple in construction, make
With convenient.
The technical solution adopted in the utility model is：
A kind of comprehensive distribution box cable protection curved head type string holes, including the string holes on distribution box body, in addition to
External curved head type string holes cover and insulation rubber gasket, insulating cement gasket diameters and string holes diameter matches, and the rubber gasket parcel line that insulate
Hole circumferential edge edge；Described external curved head type string holes cover includes gasket seal, stainless steel bend and installing plate, and installing plate is provided with
The periphery welding of the through hole to match with the upper port bore of stainless steel bend, the upper end of stainless steel bend and the through hole of installing plate
It is integrated, installing plate is provided with mounting hole, and matches and be provided with galvanized bolt, is fixed on the back side of installing plate by galvanized bolt
String holes position on the outside of distribution box body, and the center of through hole and string holes is on the same axis；Installing plate and distribution box body it
Between gasket seal is set.
The lower ending opening circumference of described stainless steel bend is provided with insulating protection circle.
Also include the built-in curved head type string holes cover in the distribution box body, the structure of built-in curved head type string holes cover with it is external
The structure of curved head type string holes cover is identical, and the lower end of built-in curved head type string holes cover is installed on the string holes position on the inside of distribution box body.
The utility model is using the rubber gasket that insulate, by insulation rubber gasket parcel string holes circumferential edge edge, it is therefore an objective to prevent cable
Scratched during disengaging by string holes, with anticreep.External curved head type is set respectively in the inner side and outer side of the string holes position of distribution box again
String holes cover and built-in curved head type string holes cover, built-in curved head type string holes cover are used in combination with external curved head type string holes cover, from top to bottom
S bend pipe road is formed, on the one hand ensures the safety of the cable of inlet-outlet line by various insulated rings, on the other hand can also play waterproof and prevent
The effect of dirt, when amount of rainfall is larger, water level needs the upper end higher than built-in curved head type string holes cover to penetrate into distribution box, improves
Waterproof effect, meanwhile, using S bend pipe road, the inlet of dust is reduced, protects component in distribution box.
The present apparatus has three pipe protection measures, is the lower end of external curved head type string holes cover together during cable passes in and out
Insulating protection circle, be insulation rubber gasket in string holes together, be also the insulation of the upper end of built-in curved head type string holes cover together
Guard ring, it can effectively protect cable to be scratched, prevent from leaking electricity.It can effectively solve the problem that and the exhausted of cable is destroyed in cable threading process
It is edge layer and the problem of preventing rainwater or dust from entering distribution box, simple in construction, it is easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is scheme of installation of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model includes the string holes 2 on distribution box body 1, in addition to external elbow
Molded line escutcheon and insulation rubber gasket 3, the insulation diameter of rubber gasket 3 and the diameter matches of string holes 2, and the rubber gasket 3 that insulate wraps up string holes 2 and justified
All edges, it is therefore an objective to prevent from being scratched by string holes 2 when cable from passing in and out, with anticreep.
Described external curved head type string holes cover includes gasket seal 4, stainless steel bend 5 and installing plate 6, is set on installing plate 6
