Summary of the invention:
The objective of the invention is to be to provide a kind of low cost, rubber filling type waterproof photovoltaic junction box easy for installation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rubber filling type waterproof photovoltaic junction box; Be provided with the box body and the lid that have cavity, offer on said box body one side and be used to run through the connection cable through hole of placing cable, the middle part in the said cavity is provided with two Clamp connecting blocks; The dual-side of bottom is provided with buckle; Respectively be connected with a metal terminal in said two Clamp connecting blocks, be connected with a diode between said two metal terminals, said metal terminal bottom is connected with cable; Said two buckles are connected to respectively on two trips of buckling groove both sides, and said buckling groove gland is on cable.
For cable clamping interface and box body are more closely cooperated; Thereby further prevent the lead off-line; Further: clamping plane in the middle of said bottom is provided with; The clamping plane is positioned at two buckle interludes in the middle of said, is provided with one at the middle part of said buckling groove and is used to be connected to the middle trip on this clamping plane, centre.
In order preventing, to cause metal terminal generation deformation and diode is come off, further: adopt between said metal terminal and the diode to be welded to connect at the diode operation adstante febre.
For the ease of the welded and installed of diode on metal terminal, further: said metal terminal is provided with the diode welding groove that is used for welding diode.
Conveniently use and prevent off-line in order to make, further: adopt machine riveting between said metal terminal and the cable.
In order to save cost, box body is designed to small size, significantly reduced the encapsulating amount, further: the opening edge in the said cavity is provided with and holds the glue plane.
Be connected more firmly in order to make between metal terminal and the Clamp connecting block, further: the contact site of said metal terminal and Clamp connecting block offers inner groovy.
In order to make terminal box and solar panel bonding more firm, be provided with the photovoltaic mucilage glue surface around the said Bottom of box body.
In order to improve the water proof and dust proof ability, and the useful life that prolongs terminal box, further: said box body adopts the mode of hermetically sealed encapsulating.
Advantage of the present invention is: the cavity volume in the said rubber filling type waterproof photovoltaic junction box is little with respect to the cavity volume in other encapsulating box bodys; Thereby significantly reduced the encapsulating amount, practiced thrift cost, portion is provided with clamping metal terminal module within it; Need not mechanical connection; Reduced manufacturing procedure, the direct clamping of cable clamping interface and box body can closely cooperate, and reaches the effect of clamping cables line.And the present invention has adopted hermetically sealed encapsulating mode that box body is sealed, and guarantees that the water proof and dust proof ability is stronger, guarantees the longer service life of terminal box.
