Description
Technical Field
The utility model relates to a photovoltaic module device field especially relates to a terminal box for photovoltaic module.
Background
A solar cell is also called a "solar chip" or a "photovoltaic cell", and is a photoelectric semiconductor sheet that directly generates electricity by using sunlight; the terminal box is generally installed on the solar cell so as to facilitate the installation of cables on the cell panel, but the surface of the terminal box can be corroded in environments such as illumination rainwater after long-time use, and the service life is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an extension terminal box life's terminal box for photovoltaic module.
The technical scheme of the utility model as follows:
the junction box for the photovoltaic module is characterized by comprising a first shell and a second shell, wherein the first shell and the second shell are both cylindrical; a first flange on the first shell is connected with a second flange on the second shell; the exposed end of the first shell and the exposed end of the second shell are both provided with at least two wire connectors, and the wire connectors are both provided with wire through holes; and the wiring terminals are all sleeved with silica gel sealing sleeves with through holes in the centers.
And a slot is formed in the side surface of the silica gel sealing sleeve.
The mounting surface of the first flange is a first inclined surface, and the mounting surface of the second flange is provided with a second inclined surface matched with the first inclined surface.
And a sealing ring is arranged between the first flange and the second flange.
And the outer sides of the first shell and the second shell are both provided with an asphalt layer.
And an aluminum foil layer is arranged outside the asphalt layer.
The utility model has the advantages that: the junction box adopts a cylindrical structure, so that more cables can be accommodated when being placed, the threading is more convenient, and the shell bodies at two ends are connected through the first flange and the second flange; through establish the silica gel seal cover on the through wires hole to the sealed effect of reinforcing through wires hole department.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Wherein: FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the aluminum foil layer structure of the present invention;
in the attached drawing, 1 is a first shell, 2 is a second shell, 3 is a first flange, 4 is a second flange, 5 is a connector lug, 6 is a silica gel sealing sleeve, 7 is a slot, 8 is a first inclined plane, 9 is a second inclined plane, 10 is an aluminum foil layer, and 11 is an asphalt layer.
Detailed Description
Referring to fig. 1-2, a junction box for a photovoltaic module is characterized by comprising a first shell 1 and a second shell 2, wherein the first shell and the second shell are both cylindrical; a first flange 3 on the first shell is connected with a second flange 4 on the second shell; the exposed end of the first shell and the exposed end of the second shell are both provided with at least two wire connectors 5, and the wire connectors are both provided with wire through holes; and the wiring terminals are all sleeved with silica gel sealing sleeves 6 with through holes in the centers. The junction box adopts a cylindrical structure, so that more cables can be accommodated when being placed, the threading is more convenient, and the shell bodies at two ends are connected through the first flange and the second flange; through establish the silica gel seal cover on the through wires hole to the sealed effect of reinforcing through wires hole department.
And a slot 7 is formed in the side surface of the silica gel sealing sleeve. The sealing sleeve is clamped on the cable by arranging the groove, and the sealing sleeve moves towards the connector lug after being clamped on the cable and moves to the end part of the connector lug; because the seal cover adopts the silica gel material, has better reversible deformation's high elasticity, consequently not only can firmly block the cable and make between the cable can be inseparabler for sealed effect is better, and the through-hole radius on the seal cover is less than through wires hole radius.
The mounting surface of the first flange is a first inclined surface 8, and the mounting surface of the second flange is provided with a second inclined surface 9 matched with the first inclined surface. Because the installation face of first flange and second flange is the inclined plane, the use of mounting structure cooperation sealing washer has better waterproof dustproof effect like this.
And a sealing ring is arranged between the first flange and the second flange. Greatly improving the sealing effect.
And the outer sides of the first shell and the second shell are both provided with an asphalt layer 11. Have better waterproof sealing effect through setting up the pitch layer.
And an aluminum foil layer 10 is arranged outside the asphalt layer. Through setting up the aluminium foil layer, can effectively reflect the sunlight, reduce the temperature in the terminal box, keep the invariant of temperature.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
