It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
As shown in figs 1 to 6, a kind of metal junction box of the present invention includes housing 100, collection string holes 111, cap 140, separated time
Plate 200, branch hole 221, separated time component 222, deconcentrator 223 and line pressing component 120.
In the present invention, punching press sheet metal process is the processing by shearing technique, punching and corner cut by sheet metal
A series of processing technologys such as technique and bending make so that the sheet metal processed meets mechanical processing technique and can be right
Complicated surface is handled, and the housing 100 in the present invention belongs to metal material, and housing 100 and cap with cap 140
140 surface is related to the mechanical processing technique of many places and complicated surface treatment, and therefore, the present invention uses punching press sheet metal process
Process housing 100 and cap 140 so that housing 100 with cap 140 in the case where not changing virgin metal material, two
Degree of protection reaches IP55 degree, and (IP also known as shell protection grade, IP degree of protection, dustproof and waterproof or IP grades, IP prevent
Shield grade is made up of two numerals, the grade that first digit represents that light fixture is dust-proof, prevents foreign object from invading；Second digit
Represent light fixture blocks moisture, the tightness of waterproof intrusion.Numeral is bigger, represents that its degree of protection is higher；IP55 first number
Word 5 represents dust-proof, specifically, prevent foreign object from invading, though dust can not be entirely prevented to invade, the amount of the dust of intrusion can't
The normal operating of light fixture is influenceed, second digit 5, which represents, prevents the water of injection from immersing, specifically, preventing from all directions by spraying
The water that mouth ejects causes to damage into light fixture.)
Hot dipping zinc technology is that housing 100 and cap 140 are immersed in liquid Zn, and the stop regular hour makes housing 100
Interpenetrated diffusion with liquid Zn and cap 140 and the atom between liquid Zn, at this moment housing 100 and cap 140
Surface forms one layer of protection zinc layers (zinc-iron alloys layer) due to zinc granule accumulation, and the alloy-layer has fine and close, uniform, bonding jail
Solid, bright, corrosion resistant the features such as, in the present invention, housing 100 and cap 140 are invaded into zinc technology using heat and made so that shell
Body 100 is respectively provided with protection zinc layers with cap 140, in this way, not only increasing the anti-corrosive properties of the housing 100 and cap 140, also extends
