Positioning column corresponding with the location hole on the electrically-conductive backing plate is provided on box body, the photovoltaic junction box of this structure needs to divide
Each electrically-conductive backing plate is not installed, then one-way conduction element is placed on electrically-conductive backing plate and specifies region and welds, installation is more not
Just, the set-up time is long.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of photovoltaic wiring for facilitating and installing to save labour turnover
Box.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows: a kind of photovoltaic junction box, including cover board and
The box body snapped together with cover board is provided with electrical connection module in box body, offers wiring notch on box body, on wiring notch
It is provided with inserting type cover board, electrical connection module includes electrically-conductive backing plate and three one-way conduction elements being disposed thereon, conductive base
Plate includes plate-like body, and there are four L-shaped connection dististyle, plate-like body other end two sides to distinguish punching press for the punching press of plate-like body one end
There are two the cable connection port that section is U-shaped, cable connection port passes through soldering block and the cable thread end phase for passing through wiring notch
Connection, one end that cable stretches out box body are equipped with connector, and the positioning that placement one-way conduction element is stamped in plate-like body is recessed
Slot is installed at least two location holes in the plate-like body of electrically-conductive backing plate, be provided on box body on the electrically-conductive backing plate
The corresponding positioning column of location hole.
As a preferred solution, it is equipped at the side of connection dististyle in the plate-like body in positioning groove small
In the evacuation groove or escape port of the positioning groove side channel wall length.
As a preferred solution, distinguish at the stitch for corresponding to each one-way conduction element in the plate-like body
Equipped with locating slot.
As a preferred solution, the one-way conduction element is stamp-mounting-paper diode.
The beneficial effects of the present invention are: electrically-conductive backing plate includes plate-like body, plate due to the electrically-conductive backing plate for using whole piece
For one end punching press of shape ontology there are four L-shaped connection dististyle, it is U-shaped that punching press is distinguished there are two section in plate-like body other end two sides
Cable connection port is stamped with the positioning groove for placing one-way conduction element in plate-like body, opens in the plate-like body of electrically-conductive backing plate
At least two location holes are provided with, positioning column corresponding with the location hole on the electrically-conductive backing plate are provided on box body, significantly
The installation for facilitating electrically-conductive backing plate and one-way conduction element, improves efficiency, saves cost of labor；And due to electrically-conductive backing plate
For an entirety, allow to first complete before stamping to be electroplated, and rack plating process can be used, electroplating cost is lower, and seperated
The electrically-conductive backing plate of formula can only then carry out barrel plating after punching press, cumbersome, at high cost.
It is less than the positioning groove side channel wall due to being equipped at the side of connection dististyle in plate-like body in positioning groove
The evacuation groove or escape port of length allow and are more easy to be put in place when placing one-way conduction unit.
It is respectively equipped with locating slot at the stitch for corresponding to each one-way conduction element in the plate-like body, so that unidirectionally
The location and installation of onunit becomes more to be easy.
