Embodiment 1

[0036] as follows figure 1 , 2 As shown, the box cover 1 is set to the following shape, which is formed by one-time injection molding. The box cover 1 is surrounded by a thin edge that is clamped with the box body, and the bottom of one side is provided with a protective cover perpendicular to the side of the box cover 1. wing. The shape of the box cover 1 is corresponding to the structure of the box body 2, which can completely occupy the space other than the external circuit components in the box body 2, so as to ensure that there is no extra space for the external circuit during assembly, thereby solving the common thermal expansion of the junction box Cold shrinkage problem. At the same time, the box body 2 is set to be integrally injection-molded into the shape of the box body 2 as shown in the figure by connecting the terminal parts connected by the positioning pin 24 and the plastic material as shown in the figure, and the box body 2 includes positive and negative two...

Embodiment 2

[0040] as follows figure 1 , 2 , 3, the box cover 1 is set to the following shape, one-time injection molding, the box cover 1 has a thin edge around the box body, and the bottom of one side is perpendicular to the side of the box cover 1. wings. The tail of the wings has a stepped structure, and the shape of the box cover 1 is corresponding to the structure of the box body 2, which can completely occupy the space other than the external circuit components in the box body 2, ensuring that there is no redundant external circuit during assembly space, so as to solve the common problem of thermal expansion and contraction deformation of junction boxes. At the same time, the box body 2 is set as shown in the figure, and the terminal part connected by the positioning pin is integrally injected with the plastic material into the shape of the box body 2 as shown in the figure. The box body 2 includes two positive and negative wires. post, the positive and negative terminals are in...

Embodiment 3

[0043] Such as Figure 4 As shown, the lid 1 is set as follows Figure 5 , Figure 6 The shape shown is one-time injection molding. The box cover 1 is surrounded by a thin edge that is clamped with the box body 2, and the bottom of one side is provided with a wing perpendicular to the side of the box cover 1. The box cover 1 The shape corresponds to the structure of the box body 2, and the space other than the components in the box body 2 can be completely occupied, so as to ensure that there is no extra space for the external circuit during assembly, and avoid the problem of thermal expansion and contraction deformation that may occur in the junction box. The box cover 1 is provided with heat conduction blind holes to expedite the dissipation of heat generated by components, especially the diode 5 . At the same time, the box body 2 is set as a terminal Figure 10 , Figure 11 The 21, 22 in it are connected by the positioning pin 24 Figure 9 The terminal part and the pla...

Abstract

The invention discloses a rapid connecting type photovoltaic junction box with a shelter. The junction box comprises a box body, a box cover, a positive binding post, a negative binding post and a bypass diode, wherein the positive binding post and the negative binding post are composed of internal and external binding posts respectively, the box body and the box cover are of an integrated structure, a part of the box cover can be opened from one side of the box cover to be connected with the box body through a side spreading portion in a snapping mode, and the box cover is provided with heat dissipation holes. The box body is provided with the shelter which is perpendicular to a box body main portion so that the shelter is applicable to a solar cell panel with bus bars which are led out from one side of the solar cell panel, and the tail of the shelter is provided with a step type structure so that two sub-junction boxes can form a{-shape junction box to lead out electrodes of a two-side cell. The internal and external binding posts are of an integrated structure and are integrated with the box body in an injection molding, and the internal binding post is connected with the bus bars in a pressing mode. The bypass diode is located on an external circuit, the external binding post is provided with a plier type structure which is used for achieving labyrinth type connection, and the external junction wire is led in from a leading wire port on one side of the junction box.

Description

technical field [0001] The invention relates to an electrode lead-out attachment device for solar cell photovoltaic modules, so as to connect the current lead-out photovoltaic module with electrical appliances or photovoltaic arrays or other forms of buses or cables, especially suitable for double-sided solar cells with double-sided leads module. Background technique [0002] Photovoltaic junction boxes are known as an accessory device for connecting solar cell photovoltaic modules with other solar cell photovoltaic modules, distribution boxes, buses and cables. As an indispensable link, the reliability and reasonable design of photovoltaic junction boxes are very important. [0003] One problem of the photovoltaic junction box is that moisture will enter the solar panel along the external connection line, through the terminal post and the confluence strip, and affect the life of the solar cell. No matter the gas-permeable membrane or filter material in the prior art can on...
