Description

Technical Field

[0001] The utility model relates to the technical field of solar energy controllers, in particular to a solar energy controller which is convenient for wiring. Background Art

[0002] A solar controller is a device used to manage and regulate the transmission of electrical energy in a solar power generation system. It is mainly responsible for obtaining electrical energy from solar panels and storing it in batteries, while preventing the batteries from being overcharged, over-discharged or overloaded, thereby extending battery life and ensuring efficient operation of the system. The interior of a solar controller usually includes a controller motherboard and terminal blocks for connecting wires. By connecting the positive and negative poles of each terminal as marked, the stable operation of the solar power generation system is ensured.

[0003] In traditional solar controllers, when the wires are connected to the main board or the terminals on the main board, the excess wires extending outward are prone to shaking or intertwining, especially when there is a lack of effective fixing and restriction measures. The wires may become loose during use, affecting the reliability and safety of the equipment, and increasing the degree of clutter inside the equipment, reducing the overall aesthetics of the equipment and the efficiency of subsequent maintenance and repair. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, one purpose of the utility model is to provide a solar controller that is easy to wire. The solar controller that is easy to wire surrounds the wires in the solar controller as a whole through a U-shaped plate inside the shell and a C-shaped plate on the top of the bottom plate, thereby limiting the position of the wires to avoid shaking and improving stability.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a solar controller that is easy to wire, comprising a shell, a bottom plate is installed with a buckle at the bottom of the shell; a plurality of fixed plates are installed on the top of the bottom plate at equal intervals, and two C-shaped plates are symmetrically installed on the top of each of the fixed plates, and the outer wall of the C-shaped plate is provided with arc-shaped convex ridges; a cross plate is fixedly connected to the inside of the shell, and a plurality of U-shaped plates are installed on the bottom of the cross plate at equal intervals, and the inner wall of each U-shaped plate is symmetrically provided with two arc-shaped grooves, and the shape of the arc-shaped convex ridges matches the shape of the arc-shaped grooves.

[0007] Preferably, the top inner wall of the shell is symmetrically provided with four threaded barrels, and the bottom plate is symmetrically penetrated by four bolts, and one end of the bolt is threadedly connected to the inside of the threaded barrel.

[0008] Preferably, connecting plates are fixedly connected to both sides of the shell, and threaded holes are provided on the connecting plates.

[0009] Preferably, a plurality of sockets are arranged equidistantly on the front surface of the housing.

[0010] Preferably, a heat sink is installed at the bottom of the base plate.

[0011] Preferably, the C-shaped plate is a C-shaped elastic plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: in the utility model, the wire passes through the C-shaped plate on the fixed plate to limit the left and right deviation of the wire. After the wire is connected to the mainboard terminal, the bottom plate is buckled on the bottom of the shell, so that the inner wall of the U-shaped plate inside the shell gradually fits the outer wall of the C-shaped plate, driving the arc-shaped convex ridges to be inserted into the arc-shaped groove, so that the U-shaped plate and the C-shaped plate surround the wire as a whole, limit the shaking of the wire in the shell, improve stability, and facilitate inspection and observation of the wire direction.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 2 The embodiment of the utility model provides a solar controller which is easy to connect, including: a shell 1 and a bottom plate 2.

[0020] In this embodiment, Figure 1 and Figure 3 As shown, the base plate 2 is snap-fitted to the bottom of the housing 1, and the solar controller mainboard is installed on the base plate 2. Four threaded tubes 11 are symmetrically arranged on the top inner wall of the housing 1. Four bolts 12 are symmetrically passed through the base plate 2, and one end of the bolt 12 is threadedly connected to the inside of the threaded tube 11.

[0021] When in use, the outer shell 1 and the base plate 2 form a solar controller outer shell structure, and the mainboard of the solar controller is installed on the base plate 2. After the mainboard is connected to the wires, the base plate 2 is snapped onto the bottom of the outer shell 1, and the bolts 12 penetrate the base plate 2 and are connected to the inside of the threaded tube 11 to complete the assembly of the outer shell 1 and the base plate 2.

[0022] For further reference, Figure 1 Both sides of the shell 1 are fixedly connected with connecting plates 6, and the connecting plates 6 are provided with threaded holes. The shell 1 can be installed on a wall or a plane through the connecting plates 6 on both sides and fixing screws passing through the threaded holes.

[0023] In this embodiment, Figure 1-Figure 4 As shown, a plurality of fixed plates 3 are installed at equal intervals on the top of the bottom plate 2, two C-shaped plates 4 are symmetrically installed on the top of each fixed plate 3, and the outer wall of the C-shaped plate 4 is provided with an arc-shaped convex ridge 13. A cross plate 8 is fixedly connected to the inside of the shell 1, and a plurality of U-shaped plates 7 are installed at equal intervals on the bottom of the cross plate 8. Two arc-shaped grooves 9 are symmetrically provided on the inner wall of each U-shaped plate 7, and the shape of the arc-shaped convex ridge 13 matches the shape of the arc-shaped groove 9.

[0024] When connecting the wire, the wire can pass through the two symmetrically arranged C-shaped plates 4 on the fixed plate 3, so that the two C-shaped plates 4 can half cover the wire and limit the left and right deviation of the wire. After the wire is connected to the mainboard terminal and is located in multiple C-shaped plates 4 in sequence, the bottom plate 2 can be snapped to the bottom of the shell 1, and the inner wall of the U-shaped plate 7 inside the shell 1 gradually fits the outer wall of the C-shaped plate 4, and finally the arc-shaped convex ridges 13 of the outer wall of the C-shaped plate 4 are snapped into the arc-shaped groove 9 of the inner wall of the U-shaped plate 7, so that the U-shaped plate 7 as a whole surrounds the C-shaped plate 4, forming an overall covering for the wire.

[0025] It should be noted that the C-shaped plate 4 is a C-shaped elastic plate. When the inner wall of the U-shaped plate 7 fits against the C-shaped plate 4 , the C-shaped plate 4 made of elastic plate material can be slightly deformed, which facilitates the arc-shaped convex rib 13 to move into the arc-shaped slot 9 .

[0026] like Figure 1 and Figure 2 As shown, a heat sink 10 is installed at the bottom of the base plate 2. The heat sink 10 can increase the heat dissipation area at the bottom of the base plate 2 and increase the heat dissipation effect of the solar controller.

[0027] Specifically, the front surface of the housing 1 is provided with a plurality of sockets 5 arranged equidistantly, and external connection wires can enter the housing 1 through the sockets 5. At the same time, the sockets 5 can expand the installation wiring interface to facilitate the external wires to connect to the solar controller through the plug.

[0028] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: In the utility model, the shell 1 and the base plate 2 constitute the shell structure of the solar controller, and the mainboard of the solar controller is installed on the base plate 2, and multiple wires are connected to the mainboard wiring terminals.

[0029] When the wires are connected, they can pass through the two symmetrically arranged C-shaped plates 4 on the fixed plate 3, so that the two C-shaped plates 4 can half-cover the wires and limit the left and right deviation of the wires. After the wires are connected to the mainboard terminals and are located in sequence on multiple C-shaped plates 4, the bottom plate 2 can be snapped on the bottom of the outer shell 1, and the inner wall of the U-shaped plate 7 inside the outer shell 1 gradually fits the outer wall of the C-shaped plate 4, and finally the arc-shaped convex ridges 13 of the outer wall of the C-shaped plate 4 are snapped into the arc-shaped grooves 9 on the inner wall of the U-shaped plate 7, so that the U-shaped plate 7 as a whole surrounds the C-shaped plate 4, forming an overall covering for the wires, limiting the wires from shaking or interlacing up and down or left and right in the outer shell 1 of the solar controller, thereby improving the stability of the wires in the solar controller and facilitating maintenance personnel to observe the routing direction of the wires after wiring.

[0030] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
