Background

In a photovoltaic energy power generation system, a photovoltaic junction box is a key part for energy output of a photovoltaic cell panel and plays a role of a current transfer station. Generally, a photovoltaic junction box is fixedly installed on a photovoltaic cell panel, and then a bus bar of the photovoltaic cell panel is connected with an element inside the photovoltaic junction box in a welding or clamping manner, so that electric energy in the photovoltaic cell panel can be conducted out through the photovoltaic junction box; after the wiring is completed, the inside of the box body of the photovoltaic junction box needs to be sealed so as to meet the waterproof and dustproof requirements of the inside of the photovoltaic junction box, and therefore the junction of the bus bar and the element is prevented from being leaked by water vapor entering the junction box, and the photovoltaic cell panel is burnt.

At present, an external screw or pouring sealant is usually adopted to seal the interior of a box body of a photovoltaic junction box, but a screw hole is reserved outside a battery adopting a screw structure and is directly communicated into a battery shell, or a screw groove is reserved outside the shell, so that water or dust is easily accumulated, the water or dust permeates into the interior of the battery to damage a circuit in the battery, and the waterproof and dustproof performance is poor; after the pouring sealant is adopted to seal the interior of the box body of the photovoltaic junction box, the pouring sealant and the box body cannot be separated, the box body is not easy to detach, if the junction of the junction area and the element fails, the photovoltaic junction box cannot be opened for maintenance, the whole box body can only be cut off from the photovoltaic cell panel, and therefore the photovoltaic cell panel can be damaged.

Disclosure of Invention

In order to solve the technical problem, the utility model discloses a quick detachable photovoltaic cell sealing junction box, include: box body and top cap, the box body is the open cavity holding chamber in top, and the opposite flank of box body is equipped with the wiring mouth, and the bottom edge of box body is equipped with the eaves limit of outside extension, be equipped with the stealthy magnetic screw of several on the eaves limit, top cap and box body looks adaptation, top cap cladding in the box body outside, the position that corresponds stealthy magnetic screw on the top cap is equipped with stealthy magnetic bolt, and the position that corresponds the wiring mouth on the top cap is equipped with slick and sly breach.

Furthermore, be equipped with the elastic sealing circle on the eaves limit, stealthy magnetism screw runs through the fixed setting of elastic sealing circle on the eaves limit.

Further, be equipped with the recess on the eaves limit, block elasticity sealing washer in the recess, stealthy magnetism screw runs through in the fixed recess that sets up on the eaves limit of elasticity sealing washer.

Furthermore, four invisible magnetic screws are arranged and are positioned at four corners of the box body.

Furthermore, the wiring port is provided with a wiring terminal, and the wiring terminal and the box body are integrally formed.

The utility model discloses introduce the photovoltaic cell field with current stealthy magnetic screw technique, combine together through stealthy magnetic screw and photovoltaic cell shell, hide the screw hole in the battery case, make the battery can satisfy corresponding waterproof dustproof requirement, also convenient to detach when guaranteeing the battery seal, make the battery more pleasing to the eye easily clearance.
