Description
Technical field
The utility model is related to a kind of photovoltaic junction box sealing structures, belong to terminal box technical field.
Background technology
In the electric connection technology of solar power system, generally use photovoltaic terminal box realizes photovoltaic module
Electrical connection between inverter.In view of the application scenario of terminal box is typically outdoor environment, therefore prevent the media such as rainwater
It is a more important consideration factor in terminal box design to penetrate into terminal box to influence internal electrical connection.In existing photovoltaic
In the sealing structure of terminal box, the upper and lower covers of terminal box are connected by bayonet or fastener, and sealing is by upper and lower in upper and lower covers
Squeeze what rubber seal was sealed, installation is inconvenient, easy to fall off to cause great quality accident；Also have and realized by inside and outside extruding
Sealing, but need mould and die accuracy high, it easily causes lateral shell cover and squeezes to form stress deformation, poor sealing is caused to form quality thing
Therefore.
Invention content
Technical problem to be solved by the utility model is to provide a kind of convenient for assembly, the photovoltaic junction box of good airproof performance
Sealing structure.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of photovoltaic junction box sealing structure, including terminal box body and upper cover, the box body include for accommodating electricity
The cavity of road module and for connecting the connecting pin for being located at four side of the box body with the upper cover, the upper cover include top surface with
And the joint end positioned at four sides, the connecting pin include the card slot for being clamped with the joint end, the card slot and the card
Connecing end, contact surface matches in the inner part, and Yu Youyi is U-shaped gap, and the gap is used for injecting glue, item is equipped at the top of the connecting pin
Shape block tongue, for blocking the gap open top and being clamped with the upper cover.
The gap bottom surface is equipped with several through holes.
The joint end is stepped.
The joint end is rough surface with glue-contact face.
The box bottom is equipped with shallow slot.
Seamless contact between the block tongue on four side of the box body.
The advantageous effect that the utility model is reached：Box body connecting pin is arranged with upper cover joint end using said combination, leads to
Encapsulating process can be simplified using the setting of through hole by crossing encapsulating and can reach fixed and sealing effect, by box body
While fixed, pass through through hole excessive glue, you can realize above-mentioned fixed function, be arranged using shallow slot, glue can be guided to flow to.
