Portion's cable conducting.There is diode in terminal box, ensure that component can be worked normally when being in the light.
Existing photovoltaic cell component be divided into conventional single crystal photovoltaic component and it is very burning hot in recent years, performance is more excellent
The double glass photovoltaic modulies of polycrystalline more.It is also different for the mode of busbar access due to the difference of component, and existing terminal box
Produced both for a certain photovoltaic cell component institute independent design, can not meet the need of different photovoltaic cell components at the same time
Ask, this results in needing to prepare the different mould of more sets and equipment during production, causes cost increase, also adds and adopt for construction party
The difficulty that purchase and maintenance are replaced.
The content of the invention
In order to overcome the above-mentioned deficiency of the prior art, the utility model provides a kind of universal photovoltaic junction box.
The technical scheme in the invention for solving the technical problem is：A kind of universal photovoltaic junction box, including box body, set
Metallic support and diode in box body are put, the longitudinally connected hole for connecting busbar is offered on the metallic support
With lateral connection hole.
Further, the metallic support raises up to form diode support frame, and the diode is arranged at described
Diode support frame on.
Further, the box body includes base and lid, and the both sides of the base offer the first card slot, the lid
The both sides of body are equipped with the first buckle, and described first buckles into first card slot.
Further, a tension disc is further included, the side of the box body is equipped with the connecting portion for being used for being connected into cable, described
Offer the second card slot on tension disc, the connecting portion is equipped with the second buckle, described second buckle into described in the
In two draw-in groove, the connecting portion forms the string holes being adapted with cable after being fastened with the tension disc.
Further, is equipped with divider wall in the base, between the divider wall and the outer wall of the base equipped with every
From groove.
The beneficial effects of the utility model are：In use, when single crystal photovoltaic component of the photovoltaic cell component for routine,
Busbar can be from the longitudinally connected hole access on metallic support；When photovoltaic cell component glass photovoltaic module double for polycrystalline, converge
Single crystal photovoltaic component can both be met from the lateral connection hole access on metallic support so as to fulfill single terminal box by flowing bar
Use demand, can also meet the use demand of the double glass photovoltaic modulies of polycrystalline.Meanwhile one set of die need to be only used in production and is set
It is standby, greatly save production cost.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1~Fig. 5, a kind of universal photovoltaic junction box, including box body, 1 and of metallic support that is arranged in box body
Diode 2, longitudinally connected hole 3 and lateral connection hole 4 for connecting busbar 15 are offered on the metallic support 1.
In the present embodiment, the metallic support 1 raises up to form diode support frame 5, and the diode 2 is set
In on the diode support frame 5.Diode 2 in existing photovoltaic junction box be all disposed within greatly adjacent metallic support 1 it
Between, without specific supporting structure, using the diode support frame 5 in the present embodiment, it can effectively support diode 2 and right
Diode 2 carries out reliable spacing so that photovoltaic junction box is more reliable and more stable when in use.
In the present embodiment, the box body includes base 6 and lid 7, and the both sides of the base 6 offer the first card slot
8, the both sides of the lid 7 are equipped with the first buckle 9, and the described first buckle 9 is buckled into first card slot 8.Pass through
The cooperation of one buckle 9 and the first card slot 8 so that the dismounting of terminal box is more convenient, being capable of effective improving production efficiency.
In the present embodiment, a tension disc 10 is further included, the side of the box body is equipped with the connection for being used for being connected into cable 11
Portion 12, offers the second card slot 13 on the tension disc 10, and the connecting portion 12 is equipped with the second buckle 14, and described the
Two buckles 14 are buckled into second card slot 13, and the connecting portion 12 is formed after being fastened with the tension disc 10 and cable
11 string holes being adapted.Cable 11 there is a phenomenon where bending causes to rupture, and then influences at thereto
The normal use of cable 11；And existing cable 11 and the connection of terminal box mostly use ultrasonic bonding, this mode
