Problems solved by technology

[0002] Among the existing photovoltaic products, the junction boxes used in them use many original parts, and the processing technology is relatively complicated. The most important thing is that they cannot be completely sealed. Exposure to the sun and long-term use will cause some waterproof components to age and become invalid. Once water enters the junction box, the consequences will be disastrous
In the same industry, even the same type of glue-filling junction box has a large box body, which leads to an increase in the amount of glue-filling, and the direct impact is to increase the cost

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] combine Figure 1~4 A glue-filled waterproof photovoltaic junction box is shown, which is provided with a box body 1 and a box cover 2 with a cavity 1-1, and a wiring cable channel for placing cables 6 is opened on one side of the box body 1. Hole 1-6, the middle part of the cavity 1-1 is provided with two clamping modules 1-2, and the two sides of the bottom are provided with buckles 1-4, and the inside of the two clamping modules 1-2 Each clamping connection has a metal terminal 5. In order to make the connection between the metal terminal and the clamping module stronger, an inner groove 5-2 can be provided at the contact position between the metal terminal 5 and the clamping module 1-2. There is a diode 4 welded on the metal terminal 5, and the two ends of the diode 4 can be installed in the diode welding groove 5-1 of the metal terminal 5 f...

Abstract

The invention relates to a junction box, in particular to a glue-filling waterproof photovoltaic junction box which is provided with a box body with a cavity and a box cover, wherein one side of the box body is provided with a connection cable through hole through which a placed cable is penetrated; two clamping modules are arranged in the middle part of the cavity, and buckles are arranged at two sides of the bottom part of the cavity; the two clamping modules are clamped with a metal terminal respectively, a diode is connected between the two metal terminals, and the bottom parts of the metal terminals are connected with the cable; and the two buckles are respectively clamped on two clamping hooks at two sides of a clamping groove, and the clamping groove is pressed on the cable. The glue-filling waterproof photovoltaic junction box adopts a small-volume box design, thus reducing glue-filling quantity and saving cost; pressing and clamping manners among elements are adopted in manufacturing and processing of the junction box, thus avoiding use of mechanical connection and achieving energy conservation and environmental protection; and a glue-filling manner is adopted for sealing the junction box, thus improving tightness and water resistance.

Description

Technical field: [0001] The invention relates to a junction box, in particular to a glue-filled waterproof photovoltaic junction box. Background technique: [0002] Among the existing photovoltaic products, the junction boxes used in them use many original parts, and the processing technology is relatively complicated. The most important thing is that they cannot be completely sealed. Exposure to the sun and long-term use will cause some waterproof components to age and become invalid. Once water enters the junction box, the consequences will be disastrous. In the same industry, even the same kind of glue-filled junction box has a large box body, which leads to an increase in the amount of glue-filled, and the direct impact is to increase the cost. Invention content: [0003] The purpose of the present invention is to provide a low-cost, easy-to-install glue-filled waterproof photovoltaic junction box. [0004] The technical solution adopted by the present invention to s...
