Description

FIELD OF THE INVENTION

The utility model relates to an assembly type, in particular to an assembly type of a solar energy control system.

BACKGROUND OF THE INVENTION

All connection boxes for a solar energy control system are made of integrated cast iron. Although a few manufactured models are offered with a cover and a box, they must be post injection molded to provide an integral seal. Since a disconnection is not available, the control box must be completely removed in case of failure of the internal electrical elements. This can damage the solar panel to the extent of significant waste. Since the electrical elements in the junction box are still connected by irreversible welding operations, it becomes difficult to weld welding strips to the box in case of disassembly. In addition, integrated ultrasonic welding can compromise strength; whereas integrated injection molding through molten plastic at high temperatures can cause burns to the cables. Such defects affect the widespread use of solar panel control junction boxes in the field of solar energy.

Alternatively, the existing cable connections rely only on the 1st and 2nd sockets to connect two separate ports that were originally disconnected. This type of connection is only available for simple mechanical connections and can not ensure perfect conductivity. In fact, the conductivity of the cables will decline after a certain period of operation. Furthermore, conventional connections that are connected by screw connection, lead to an irreversible combination of the cable connection and to the extent that the cable can not be separated and maintenance with separate cables is not possible. Moreover, because existing connections rely on leaf springs to position the cable, the leaf spring without external structural definition would result in disengaging the incoming connection from two cable sections that would be mounted in that connection. Due to the aforementioned defects, the connection of the cables is affected by several factors; Such complicated connections are also impractical for installation at the installation site. For this reason, the functional performance is still in need of improvement.

This is advantageous for determining the distribution position of the wire strip ( 9 ) with the additional rod ( 8th ). However, it is also possible, the common arrangement of the wire strip ( 9 ) and the additional rod ( 8th ) and the outer wall of the cable frame ( 7 ) in order to ensure optimum elastic deformation of the wire strip ( 9 ), so as to facilitate the clamping of the incoming cable connection.

Furthermore, the connection box ( 21 ) and the corresponding position on the lid, each with a bayonet socket ( 10 ) and ( 11 ) in order to ensure an overall stable compression of the connection box and to increase the water resistance. Alternatively, the bayonet base ( 10 ) and ( 11 ) also at the corresponding positions on the box lid and the aforementioned terminal box ( 21 ). In view of the fact that many outgoing cables in the connection box ( 21 ), the cable protection plate is fitted with a cable receiving cover ( 4 ) to extend the conventional expansion space of the cable. The normal location of the cable receiving cover ( 4 ) can solve the problem of the projected space occupied by maximum bent cables. However, with respect to the strength of the terminal box for a solar energy control system, a stiffening ( 12 ) in the connection box ( 21 ) and accordingly a cable reinforcement ( 5 ) used.

The structure of the assembly for a solar energy control system according to this utility model aims to provide a maximum internal cavity in the junction box (FIG. 21 ) by position placement between heat dissipation cavity ( 3 ) and connection terminal ( 2 ) and thus guarantee perfect heat dissipation.
