Lie prostrate capacity of installed generator annual with more than 40 percent speedup development.Terminal box is connected as the bypass of photovoltaic electrification component
Device, its demand is increasing, and to rated power, reliability, the requirement more and more higher of small size installation.Therefore, wiring
Box needs constantly upgrading to meet the growth requirement of photovoltaic industry.
The generating efficiency of traditional one side photovoltaic module only has 20% or so, and market user's end is to high-power high-efficiency
Demand is increasing, demand sustainable growth of the generating efficiency up to more than 30% solar double-glass assemblies.Because solar double-glass assemblies are double-side cells
Piece, therefore terminal box can not be optionally mounted at the back side as one side cell piece, without considering volume size.Solar double-glass assemblies two sides
It is cell piece, terminal box can only reduce erection space as far as possible and be arranged on frame.What in the market was commonly used is triad terminal box,
Cost is higher to install inconvenience.And single-gang junction box is limited by interior patches diode volume and secondary welding, it is impossible to accomplish
Narrower width, and take into account radiating.Module terminal box can be with arbitrarily devised inner mounting structure.Meanwhile, box structure needs inside
Encapsulating, cassette bottom portion needs the ultra-sonic welded of large area, and technique is complex.
The content of the invention
It is an object of the invention to provide a kind of narrow body photovoltaic junction box, it have it is simple in construction, the characteristics of function admirable.
The technical solution adopted in the present invention is：Narrow body photovoltaic junction box, the terminal box includes the box by cooperating
The box body that bottom and lid are constituted；Provided with embedded terminal module in the box body, the embedded terminal module includes yi word pattern from left to right
The first copper electrode terminal, the second copper electrode terminal, the 3rd copper electrode terminal, the 4th copper electrode terminal arranged, adjacent copper electricity
Diode chip for backlight unit is connected between extreme son, diode chip for backlight unit is encapsulated by modified epoxy plastic-sealed body；Meanwhile, this
One copper electrode terminal is connected with the first cable, the 4th copper electrode terminal and is connected with the second cable, and first cable extends to the left
The outside of the box body, second cable are extend out to afterwards, and the outside of the box body is extend out to after extending to the right.
First cable and the first copper electrode terminal are connected by the way of electric resistance welding.
Second cable and the 4th copper electrode terminal are connected by the way of electric resistance welding.
The second copper electrode terminal and the 3rd copper electrode terminal are embedded in the modified epoxy by way of embedded and moulded
Envelope is internal.
The first copper electrode terminal, the second copper electrode terminal, the 3rd copper electrode terminal, the 4th copper electrode terminal and the box
There is clearance for insulation between the intracavity sidewall of body.
The invention has the advantages that compared with the prior art,：It is simple in construction, function admirable.The narrow body photovoltaic of the present invention
Three parts such as the cassette bottom of prior art, box body, upper lid are reduced to only cassette bottom, two parts of upper lid by terminal box, are simplified
Product structure.Meanwhile, without using or reducing ultrasonic bonding, reduce welding difficulty；Without by the way of encapsulating, entering
One step reduces product cost.And, the gap of insulation is provided between copper electrode terminal and box body, the exhausted of product is added
Edge voltage endurance capability, through experiment, insulation voltage endurance capability is scalable to 1500V from 1000V；Cable stretches out from the left and right sides of box body,
Add creep age distance.That is, the performance of product is lifted.
