Description

Photovoltaic junction box

technical field

The utility model relates to a junction box, in particular to a junction box of a solar cell assembly.

Background technique

Solar energy generally refers to the radiant energy of sunlight. Due to its non-polluting and environmentally friendly features, it has been paid more and more attention by humans, and it is usually used in the water heater industry. Recently, with the development of society, a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy has emerged. The junction box of the solar cell module is the key connection device in the system.

The commonly used photovoltaic junction box at present includes a box body and a box cover matched with the box body. The box body includes a mounting part, a side part extending upward from the periphery of the mounting part, and formed by the mounting part and the side part to accommodate diodes and terminals. For the storage space of other components, when the photovoltaic junction box is installed, glue is generally applied on the ground of the installation part. At the same time, when the photovoltaic junction box is prepared, the ground of the installation part cannot be completely smooth, so during installation, the ground of the installation part cannot be close On the battery board, there is a gap, so that there is air between the ground of the installation part and the battery board, resulting in an unstable installation.

Contents of the invention

The technical problem to be solved by the utility model is to provide a photovoltaic junction box which is easy to install, firmly fixed and easy to maintain in view of the above disadvantages.

In order to solve the problems of the technologies described above, the technical solution of the present invention is:

A photovoltaic junction box includes a box body, a box cover, and metal terminals and diodes installed in the box body, wherein the box body is provided with positioning components required for fixing the metal terminals.

The above-mentioned photovoltaic junction box, wherein, the metal terminal is provided with two sets of symmetrical convex edges, the metal terminal is in the structure of "earth", and the two sets of convex edges cooperate with the positioning parts of the box body, It plays the role of positioning and restricting movement.

In the above photovoltaic junction box, the positioning component is composed of a first horizontal positioning component, a second horizontal positioning component and a longitudinal positioning component.

The above photovoltaic junction box, wherein, the first horizontal positioning component and the second horizontal positioning component are longitudinally arranged at the bottom of the box body, and the positions are matched with the front and rear ends of the metal terminals.

The above photovoltaic junction box, wherein the longitudinal positioning component is composed of a triangular protruding positioning block built into a positioning hole, and one end of the triangular protruding positioning block is higher than the box body.

The beneficial effects of the present invention are:

1. The first horizontal positioning card slot and the second horizontal positioning card slot cooperate with the front and rear ends of the metal terminal, which play a positioning role and prevent the metal terminal from moving forward and backward.

2. The longitudinal positioning protruding parts cooperate with the middle part of the metal terminal to play a positioning role and prevent the metal terminal from moving left and right.

3. The installation is convenient and simple, no need to use glue, which improves the heat dissipation performance, increases the service life of the product, and saves costs.
