Description
Technical field
The present invention relates to a kind of photovoltaic adapter, particularly relate to the T-type structure of a kind of photovoltaic DC-to-AC converter even
Connect the attachment structure of device, bus and branch line.
Background technology
Unidirectional current produced by photovoltaic cell component is transformed to alternating current by photovoltaic DC-to-AC converter and is fed to electricity
Net, in the process, needs to converge on total cable the electric current in each branch-off cables, the company used
Access node structure generally includes male end (bus end) and female end (line end), described male end by bus each
Heart yearn is drawn respectively, and female end is provided with the terminal electrically connected with each heart yearn, and male end is constituted with female end grafting
The branch line of T-type structure electrically connects form with bus.
The most in the art, typically go between out from bus and need, by peeling, exposed heart yearn to twine
Around lead-in wire, then the cable of exposed part is encased by electricity consumption adhesive plaster, completes lead-in wire and connects.This kind of mode is deposited
At manual wiring poor stability, the problems such as firmness is not enough, impact conducts performance, and working (machining) efficiency is low,
Batch production difficulty is big.Occur by the way of playing terminal connection on every heart yearn 111 for this, such as figure
Shown in 1, respectively by peeling, beat terminal, suit male end main body 112, the operations such as encapsulated 115, reality
The now lead-in wire to bus 113；Branch line then by setting terminal on every heart yearn, is set with female end main body,
Finally complete encapsulated 115 operations.Owing to using the mode of metal terminal 114 to go between, with manual kinking phase
Ratio, connective stability and fastness are greatly enhanced, but are not shown on the loaded down with trivial details degree of operation
The improvement write, it is still desirable to artificial participation, therefore working (machining) efficiency does not get a promotion, and affects volume production and enters
Degree.It addition, either male end or female end, it is required for arranging encapsulated layer at outer layer, i.e. utilizes encapsulated layer
Guarantee the water proofing property of adapter, but this procedure will need die sinking, on the one hand improve production cost,
On the other hand complex procedures, makes a whole set of adapter packaging efficiency decline, affects the lifting of volume of production.
