Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific drawings.

[0009] Such as Figure 1 ~ Figure 2 As shown: the junction box with an overheating protection device includes a conductor 1, a diode 2, a connector 3, a cable connection 4, a thermal switch 5, and the like.

[0010] Such as Figure 1 ~ Figure 2 As shown, the present invention includes a conductor 1 installed inside the junction box, a diode 2 is connected to the conductor 1, one end of the conductor 1 is a joint end 3, and the other end of the conductor 1 is a cable connection terminal 4, and the conductor 1 and the The cable connection end 4 is connected by a thermal switch 5 .

[0011] In the present invention, a thermal protection device (thermal switch 5) is installed between the cable connection end 4 and the conductor 1. When the diode 2 or the joint end 3 inside the junction box generates a certain high temperature, the thermal protection device automatically cuts off...

Abstract

The invention relates to a junction box with an overheating protection device. The junction box comprises electric conductors mounted in a junction box body, wherein a diode is connected to each electric conductor, one end of each electric conductor is a connector end, and the other end of each electric conductor is a cable connecting end. The junction box is characterized in that a thermoswitch is arranged between each electric conductor and the corresponding cable connecting end. According to the junction box with the overheating protection device, the high temperature protection effect of the junction box in a system is improved on the basis that the basic structure is not changed, the junction box can be prevented from burning at a high temperature, and consequently the purpose of protecting the system is achieved.

Description

technical field [0001] The invention relates to a junction box for a solar battery module, in particular to a junction box with an overheat protection device. Background technique [0002] There is no overheating protection device in the existing junction box for solar cell modules, and there is no short circuit protection when the temperature inside the junction box is enough to burn the junction box. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a junction box with an overheating protection device. When the temperature inside the junction box is sufficient to burn the junction box, the circuit is opened in time to prevent the junction box and components from being burned. [0004] According to the technical solution provided by the present invention, the junction box with an overheat protection device includes a conductor installed inside the junction box, a diode is connected to the c...
