Abstract

The invention discloses a kind of photovoltaic wiring units, including insulating body, conducting strip and diode chip for backlight unit, the conducting strip has and only two panels, is realized and electrically connected by diode chip for backlight unit, and is tightly fastened with insulating body;The insulating body has the geometry closed in plane, and the area of conducting strip more than 95% falls into the close-shaped interior of insulating body;Busbar welding hole is reserved with two conducting strips.Multiple proposed photovoltaic wiring units are connected and can play a part of terminal box in existing photovoltaic cell by the present invention, and the connection of multiple photovoltaic wiring units is more prone to mounting arrangements, the layout of photovoltaic wiring units can also be changed according to the actual requirements.

Description

A kind of photovoltaic wiring units
Technical field
The invention belongs to technical field of solar batteries, more particularly to a kind of photovoltaic wiring units.
Background technology
Solar cell is also known as " solar chip " or " photocell ", is a kind of photoelectricity using the sunshine direct generation of electricity Wafer.As long as the illumination that it is satisfied certain illumination conditions is arrived, moment output voltage and can have the situation in loop Lower generation electric current.Solar junction box is used to protect whole electricity generation system, plays a part of electric current terminal, if component is short-circuit Terminal box disconnects short circuit battery string automatically, prevents that burning out whole system connects, it is crucial that the selection of diode in line box, according to The type of cell piece is different in component, and corresponding diode also differs.In the prior art, the structure of terminal box generally comprises box Body, box body is interior to be provided with some conducting strips, for connecting solar battery sheet;It is connected between each conducting strip with diode, two pole Pipe is in parallel with component cell piece, plays bypass;The conducting strip at both ends is respectively connected with wire with the external world.
The content of the invention
It is an object of the invention to provide a kind of stabilized structure, it is easier to the photovoltaic wiring units installed and used and replaced.
Therefore, the technical scheme is that:A kind of photovoltaic wiring units, including insulating body, conducting strip and diode Chip, it is characterised in that:The conducting strip has and only two panels, is realized and electrically connected by diode chip for backlight unit, and and insulating body It is tightly fastened;The insulating body has the geometry closed in plane, and the area of conducting strip more than 95% falls into insulating body It is close-shaped in;Busbar welding hole is reserved with two conducting strips.
Further, the conducting strip is provided with connection jaws, stretches out the close-shaped outer of insulating body.
Further, the busbar welding hole on the conducting strip, the close-shaped interior of insulating body is fallen completely within.
The insulating body of the present invention surround shape for complete surrounding, forms firm structural form;Terminal box is confluxed Bar weld zone is arranged at the centre position of product so that welding busbar is easier during installation;Basis is actually needed setting simultaneously The quantity of connection jaws;Can be each one of two ends, wherein one end sets the other end to be not provided with, or two ends do not set connection jaws.
Multiple proposed photovoltaic wiring units are connected and can play terminal box in existing photovoltaic cell by the present invention Effect, and the connection of multiple photovoltaic wiring units is more prone to mounting arrangements, can also be according to the actual requirements to photovoltaic wiring list The layout of member is changed;Meanwhile multigroup conducting strip being connected with diode present in existing terminal box, and work as one of which Again problem, it is necessary to replace whole terminal box, after multiple wiring units now instead of to original terminal box, it is only necessary to The corresponding photovoltaic wiring units to go wrong are changed, reduce the overall use cost of photovoltaic cell.
Brief description of the drawings
It is described in further detail below in conjunction with accompanying drawing and embodiments of the present invention
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the internal structure schematic diagram of the present invention;
Fig. 3 is the side sectional view of the present invention.
In figure mark for:Insulating body 1, conducting strip 2, diode chip for backlight unit 3, busbar weld zone 4, connection jaws 5, wire jumper 6.
Embodiment
Referring to accompanying drawing.The present embodiment includes insulating body 1, conducting strip 2 and diode chip for backlight unit 3, and the conducting strip 2 has and only There is two panels, diode chip for backlight unit 3 is placed in one on a piece of conducting strip, and diode chip for backlight unit is realized by wire jumper 6 and another conducting strip Electrical connection, and be tightly fastened with insulating body 1;The insulating body 1 has the geometry closed in plane, conducting strip 95% Area above falls into the close-shaped interior of insulating body;Busbar weld zone 4, busbar are reserved with two conducting strips 2 Weld zone 4 falls completely within the close-shaped interior of insulating body.The number that the conducting strip sets connection jaws 5 according to being actually needed simultaneously Amount;Can be each one of two ends, wherein one end sets the other end to be not provided with, or two ends do not set connection jaws;Connection jaws stretch out exhausted Edge body it is close-shaped outer.
