Description

A solar panel junction box with double waterproof function

technical field

The utility model relates to a solar panel junction box with double waterproof functions.

Background technique

With the increasing shortage of energy in the world, my country's photovoltaic power generation industry is booming. As a kind of green and clean energy, solar energy is more and more favored by people because of its safety, cleanness and recyclability. The solar photovoltaic power generation industry has become a sunrise industry that the world is chasing. This also promotes the development of components related to the solar photovoltaic industry. As an important part of the solar cell module, the solar panel junction box is a connector between the solar cell array formed by the solar cell module and the solar cell charging control device. It is a necessary part of the photovoltaic power generation system and ensures that the solar cell panel In the thunderstorm season, it is not affected by thunderstorms and can operate safely and stably, which is a necessary measure to ensure the stable operation of the entire solar photovoltaic power generation system. At present, the existing similar products have a simple structure, consisting only of an upper cover and a lower cover. The connection between the upper and lower covers is not tight enough, causing water leakage during the thunderstorm season, which affects the operation of the electronic components inside the junction box. In addition, the junction box is connected to the solar photovoltaic cable. The method of screw connection is adopted. The disadvantage of this method is that it is cumbersome and inconvenient to operate.

Utility model content

The purpose of the utility model is to provide a solar panel junction box with good sealing effect, no water leakage and convenient and fast connection with external solar photovoltaic cables.

The technical scheme that the utility model takes:

The structural design includes an upper cover 1, a lower cover 2, six connecting components 3, a sealing ring 4, and a sealing ring 5. It is characterized in that: a sealing ring 4 and a sealing ring 5 are arranged between the upper cover 1 and the lower cover 2, and six The connection assembly 3 is arranged in parallel inside the lower cover 2 , and the connection assembly 3 and the photovoltaic cable are connected by a rotary buckle 6 .

Features and advantages of the utility model: the structural design is more compact, and two layers of sealing rings are set between the upper and lower covers to achieve a better double waterproof effect, ensuring the safe and stable operation of the battery board in the thunderstorm season; it is simpler to use the clamping connection cable mode , fast, easy maintenance.

Description of drawings

Fig. 1 is the layout diagram of the double-layer sealing ring between the upper and lower covers of the utility model.

Fig. 2 is a structural schematic diagram of the junction box of the present invention.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The product structure of the utility model is made up of upper cover 1, lower cover 2, six connecting assemblies 3, sealing ring 4 and sealing ring 5. Double-layer sealing rings 4 and 5 are used between the upper cover 1 and the lower cover 2, and buckles 6 are used to connect the connecting components and cables. When the upper and lower covers are tightly connected by the buckles evenly arranged around them, the two sealing rings arranged in between are pressed tightly, and a better waterproof effect is achieved through the double protection of the two sealing rings. In the clamping type shown in Figure 1, the cable head is pressed into the connecting component to bend the shrapnel and then rotated 90 degrees clockwise, and the shrapnel presses the cable connector to the slot of the connecting component through the elastic force. Connection is quick and easy.

Claims (1)
