Description

Technical Field

[0001] The utility model relates to the technical field of combiner boxes, and in particular to a photovoltaic combiner box which is easy to install. Background Art

[0002] A combiner box means that users can connect a certain number of photovoltaic cells of the same specifications in series to form photovoltaic strings, and then connect several photovoltaic strings in parallel to the photovoltaic combiner box. After the photovoltaics are combined in the photovoltaic combiner box, they are used together through a controller, a DC distribution cabinet, a photovoltaic inverter, and an AC distribution cabinet to form a complete photovoltaic power generation system and achieve grid connection with the city power grid.

[0003] The existing photovoltaic combiner box is usually installed by connecting a cross bar to the photovoltaic bracket, and then placing the photovoltaic combiner box on the cross bar and screwing bolts on both sides to fix it on the cross bar. This installation method requires lifting the photovoltaic combiner box to align the mounting holes of the bolts with the connection holes on the cross bar and then screwing in the bolts to connect. During the installation, the photovoltaic combiner box needs to be dragged all the time, which is laborious and troublesome. It also needs to be supported during disassembly, otherwise it will fall off. In addition, after installation, the weight of the photovoltaic combiner box will all fall on the bolts, which is not stable enough. Utility Model Content

[0004] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a photovoltaic combiner box that is easy to install.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photovoltaic junction box that is easy to install, comprising a junction box body and a box door, the box door is hinged to the junction box body at the opening of the front end face thereof, and also comprises a fixing member, a connecting buckle is provided on the back of the junction box body, the connecting buckle comprises a connecting plate and a snap-fit ​​plate, the two ends of the connecting plate are respectively connected to the junction box body and the snap-fit ​​plate, the connecting plate is located above the snap-fit ​​plate, the spacing from the snap-fit ​​plate to the junction box body is adapted to the cross bar, and the fixing member fixes the position of the connecting buckle on the cross bar.

[0006] With this arrangement, during installation, you only need to buckle the connecting buckle on the back of the combiner box body onto the cross bar on the photovoltaic bracket. At this time, the combiner box body will be hung on the cross bar by relying on the connecting buckle. After hanging it up, use the fixings to fix the position of the connecting buckle on the cross bar to complete the connection. When using the fixings, the combiner box body is in a state of being buckled on the cross bar by relying on the connecting buckle. There is no need to manually support the alignment position, which makes installation more convenient. After the connection, the weight of the combiner box body is supported by the connecting buckle. The contact area between the connecting buckle and the cross bar is large, the pressure is evenly distributed, and it is more stable. The connecting buckle can be connected to the combiner box body in various ways such as integrated setting or welding.

[0007] Furthermore, the connection buckle is provided with connection heads at positions outside the two sides of the combiner box body, and the fixing member fixes the connection buckle and the cross bar on the connection heads.

[0008] With such an arrangement, the fixings can be used on the connection heads on both sides of the combiner box body, and will not be blocked by the combiner box body during the installation process, making the installation process more convenient.

[0009] Furthermore, the fixing member is a bolt, which passes through the connecting buckle and the cross bar to connect the two.

[0010] With such arrangement, connection with bolts can be completed by simply rotating, which is convenient for installation and provides a stable connection.

[0011] Furthermore, the buckle plate is provided with a connection hole adapted to the fixing member.

[0012] In this arrangement, since the profile of the bracket used for photovoltaic is a U-shaped profile with its connecting surface facing the front end, the fixing part will enter from the U-shaped opening position of the cross bar after passing through the connecting hole on the snap plate, and then pass through its connecting surface to connect with it. When this structure needs to move the junction box body, you only need to pull out the bolt a little to make it leave the connecting surface, and then slide the junction box body on the cross bar. After moving it to a suitable position, you can re-screw the bolt, which is more convenient to adjust.

[0013] Furthermore, it also includes a connecting nut, which is threadedly connected to the fixing piece on a side of the cross bar facing the combiner box body.

[0014] With this arrangement, after the bolt passes through the connecting surface of the crossbar, it can be tightened with the connecting nut, so that the connecting buckle will tightly clamp the crossbar, making the connection more stable. After adding the nut, the crossbar can use the ordinary style with strip holes.

[0015] Furthermore, the length of the connecting plate is not greater than the width of the combiner box body.

[0016] With such arrangement, only the snap-fit ​​plate with the connection hole is present in the connector, and it is easier to bend and deform to clamp the crossbar, thus saving more materials.

[0017] Furthermore, the connecting plate is located on the top of the buckling plate, and the connecting plate and the buckling plate are connected to form a 7 shape.

[0018] With such arrangement, the connecting buckle is formed by bending a single plate, and has a simple structure and is easy to process.

[0019] Furthermore, two connecting buckles are provided, and the two connecting buckles are respectively located at the upper and lower sides of the combiner box body.

[0020] With this arrangement, the two connecting buckles are fixed simultaneously from the upper and lower sides for greater stability.

[0021] Furthermore, the snap-fit ​​plate is arranged obliquely relative to the combiner box body, and the distance between the bottom of the snap-fit ​​plate and the combiner box body is greater than the distance between the top of the snap-fit ​​plate and the combiner box body.

[0022] With such a setting, the opening of the connecting buckle is larger when inserted after the inclined setting, making it easier to insert, and the width is smaller when inserted to the bottom, making it clamped tighter. BRIEF DESCRIPTION OF THE DRAWINGS
