Junction box for photovoltaic modules for easy crimping of bus bars

Abstract

The invention discloses a photovoltaic module junction box convenient to crimp a bus bar. The photovoltaic module junction box comprises a junction box body, glass and an internal bus bar, wherein the internal bus bar is arranged in the glass, an opening is formed in the glass and is used for the junction box body to be electrically connected with the internal bus bar, a crimping groove is formed at the bottom of the junction box body and is opposite to the opening, a diode module, an external bus bar and a crimping device are arranged in the junction box body, one end of the external bus bar can be electrically connected with the diode module, the other end of the external bus bar can be placed in the opening to be electrically connected with the internal bus bar, the crimping device can be pressed onto the external bus bar when the junction box body and the glass are connected and comprises a crimping element, a conductive main body and an elastic element, the conductive main body can act upwards and downwards and is arranged in the crimping element in a penetrating way, and the elastic element sleeves the conductive main body. In the photovoltaic module junction box, a bus bar leading-out line is not needed to be arranged, the connection between the photovoltaic module junction box and the bus bar can be achieved by bonding of the junction box body and the glass, and the crimping device is arranged to stably connect the bus bar.

Description

technical field [0001] The invention belongs to the technical field of double-glass photovoltaic power generation components, and in particular relates to a photovoltaic component junction box which is convenient for crimping bus bars. Background technique [0002] At present, the back of the photovoltaic cell module junction box is usually glass. In order to facilitate the connection of the bus bar in the glass to the junction box, the lead wires of the bus bar need to be exposed outside the glass, and then the bus bar is soldered or snap-connected to the junction box terminal, so that Make the process of operation comparatively troublesome, and production efficiency reduces greatly. Moreover, this connection method is relatively unstable, and the connection between the bus bar and the terminal is not stable enough, and phenomena such as virtual welding and disconnection are prone to occur, which affects the normal use of the junction box.

[0002] At present, the back of the photovoltaic cell module junction box is usually glass. In order to facilitate the connection of the bus bar in the glass to the junction box, the lead wires of the bus bar need to be exposed outside the glass, and then the bus bar is soldered or snap-connected to the junction box terminal, so that It makes the operation process more troublesome, and the production efficiency is greatly reduced.

Moreover, this connection method is relatively unstable, and the connection between the bus bar and the terminal is not stable enough, and it is prone to false welding, disconnection, etc., which affects the normal use of the junction box
