Description
Technical field
The utility model relates to a kind of photovoltaic junction box, in particular to one kind occupy little space, simple process, structure optimization
Photovoltaic junction box.
Background technique
Photovoltaic junction box is the solar cell array that surplus solar cell module is constituted and solar charging electric control dress
Connector between setting.It is the cross-cutting comprehensive design that collection electrical design, a Machine Design are combined with material science.
For existing photovoltaic junction box usually using polyphenylene oxide as cell material, the diode binding post used is bending
's.Diode binding post is inserted into the location hole on binding post, then is welded by arc welding.But this structure needs
Certain gap is reserved between binding post and box body, increases the occupied space of terminal box.Meanwhile arc welding needs welding material
Material just can be carried out welding, and such welding manner is unstable, and welding material, which is easy to fall off, causes diode to connect not with junction block
Stablize.
Summary of the invention
In order to solve the above problem in the prior art, the utility model provide one kind occupy little space, weld stablize, at
This low and structure optimization photovoltaic junction box.
The technical scheme in the invention for solving the technical problem is:
A kind of photovoltaic junction box of structure optimization, including cable, box body, junction block and be fixed on junction block two
Pole pipe；The terminals with through-hole are tiltedly equipped on the outer wall of the box body side, the cable passes through terminals and tray interior electricity
Road connection；The junction block includes the side plate of bottom plate and two sides, and the side plate is equipped with locating slot；The diode passes through resistance
Solid welding is scheduled on the junction block.
Further, the cell material is nylon material.
Further, the box body interior base is equipped with grab, and the junction block is fixed in box body by the grab.
Further, there are two the locating slots on the side plate.
Further, the binding post of the diode does not set bending.
Junction block is fixed on Bottom of box body the utility model by grab when in use, and the binding post of diode is passed through
Locating slot on binding post side plate carries out positioning placement on junction block, then is welded diode and junction block with electric resistance welding
Connection.
The utility model has the beneficial effects that: diode binding post used in the 1, terminal box simplifies without bending
Diode production technique；2, junction block directly passes through grab and is fixed on Bottom of box body, without retaining gap, reduces terminal box and accounts for
Use space；3, welding of the diode on junction block uses electric resistance welding, saves welding material, guarantees that workpiece contact is good, is formed
Close pad, diode are not easy to loosen；4, cell material uses nylon, heat-resist, low in cost.
Detailed description of the invention
Fig. 1 is the internal structure chart of the utility model.
Fig. 2 is the side view of the utility model.
It is marked on attached drawing: 1, box body, 2, junction block, 3, cable, 4, terminals, 5,
Diode, 6, grab, 7, side plate, 8, locating slot.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1~2, a kind of photovoltaic junction box of structure optimization, including cable 3, box body 1, junction block 2 and solid
The diode 5 being scheduled on junction block 2；The terminals 4 with through-hole are tiltedly equipped on the 1 side outer wall of box body, the cable 3 is logical
Terminals 4 are crossed to connect with 1 internal circuit of box body；The junction block 2 includes the side plate 7 of bottom plate and two sides, is set on the side plate 7
There is locating slot 8；The diode 5 is fixed on the junction block 2 by electric resistance welding.Electric resistance welding does not need filling gold in welding
Category and welding material, productivity is high, and welding deformation is small, automation easy to accomplish.
In the present embodiment, 1 material of box body is nylon material.Nylon is heat-resist, is unlikely to deform, and at low cost.
In the present embodiment, 1 interior base of box body is equipped with grab 6, and the junction block 2 is fixed on by the grab 6
In box body 1.
In the present embodiment, there are two the locating slots 8 on the side plate 7.The binding post of diode 5 is located in junction block
On, facilitate automatic welding.
In the present embodiment, the binding post of the diode 5 does not set bending.Without being reserved between Bottom of box body and junction block
Gap.
Junction block is fixed on Bottom of box body by grab when the present embodiment is in use, by the binding post of diode by connecing
Locating slot on terminal side plate carries out positioning placement on junction block, then diode and junction block are carried out welding company with electric resistance welding
It connects.
The advantage of this embodiment is that it is raw to simplify diode without bending for diode binding post used in the 1, terminal box
Production. art；2, junction block directly passes through grab and is fixed on Bottom of box body, without retaining gap, reduces terminal box occupied space；
3, welding of the diode on junction block uses electric resistance welding, saves welding material, guarantees that workpiece contact is good, forms closely weldering
Contact, diode are not easy to loosen；4, cell material uses nylon, heat-resist, low in cost.
More than, the only preferable specific embodiment of the utility model, but the protection scope of utility model is not limited to
This, anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can be readily occurred in
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with right
Subject to the protection scope of claim.
