Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, and in particular to a photovoltaic connector for an inverter. Background Art

[0002] In solar photovoltaic power generation systems, photovoltaic connectors are one of the key components of the solar photovoltaic industry, connecting various devices through photovoltaic connectors. In existing inverter grid-connected systems, the electrical energy converted from each photovoltaic cell is converted from DC to AC through an inverter, which is then connected to the bus through a branch line. The bus is then connected to the next photovoltaic device (for example, a voltage stabilizer stabilizes the voltage of the entire circuit to meet the needs of the electrical device). The connector used when connecting to the bus typically includes a male end and a female end. The male end is set on one side of the branch line, and the female end is set on the bus. The male and female ends are connected together to complete the connection between the branch line and the bus.

[0003] When installing photovoltaic connectors in existing technology, bare wires are typically connected to male and female terminals. However, the connection is not secure enough and can easily become dislodged due to strong winds or human factors, affecting the stability of the connection. Therefore, it is necessary to provide a photovoltaic connector for inverters to solve the above technical problems. Utility Model Content

[0023] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0024] Example 1:

[0025] like Figure 1-5 As shown, a photovoltaic connector for an inverter of the present invention includes a photovoltaic connector body 1, which includes a sub-shell 3 and a female shell 5 arranged on the outside, and one end of the sub-shell 3 and the female shell 5 are fixedly connected to a second bend pipe 8, and a mounting groove 13 is provided on the top of the second bend pipe 8. The inner side of the mounting groove 13 is rotatably connected to the first bend pipe 7, and a plurality of upper anti-slip ridges 12 are fixedly installed on the inner side of the first bend pipe 7, and a plurality of lower anti-slip ridges 6 are fixedly installed on the inner side of the second bend pipe 8.

[0026] like Figure 1 and Figure 5As shown, the outer side of the sub-shell 3 is symmetrically provided with a first groove 2, and a U-shaped seat 10 is fixedly installed on the inner side of each first groove 2. The outer side of the female shell 5 is symmetrically provided with a second groove 4, and an elastic plug-in piece 9 that passes through the U-shaped seat 10 is fixedly installed on the inner side of each second groove 4. The opposite back surfaces of the two elastic plug-in pieces 9 are fixedly provided with a limit block 14 that contacts the U-shaped seat 10. The limit block 14 is a right-angled triangular structure, which is convenient for connecting and fixing the sub-shell 3 and the female shell 5.

[0027] like Figure 2 As shown, the upper anti-skid ridges 12 and the lower anti-skid ridges 6 are both semi-annular structures, and are both made of rubber.

[0028] During implementation, by providing a "Z"-shaped first bend 7 and a second bend 8 at both ends of the photovoltaic connector body 1, by passing the wires through the first bend 7 and the second bend 8, and using the upper anti-slip ridge 12 and the lower anti-slip ridge 6 to clamp the wires, the wires' anti-pullout ability can be enhanced, and the firmness of the connection points can be improved, which solves the technical problem in the prior art that when installing photovoltaic connectors, the exposed wires are usually connected to the male and female ends, but the connection position is not firm enough and is prone to falling off due to strong winds or human factors, thereby affecting the stability of the connection.

[0029] Example 2:

[0030] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: a second fixed block 15 is fixedly installed on the outer side of the second bent pipe 8, and a notch 18 is provided on one side of the second fixed block 15; a first fixed block 11 is fixedly installed on the outer side of the first bent pipe 7; a rotating shaft 20 is rotatably connected inside the first fixed block 11; a stopper 17 engaged with the second fixed block 15 is fixedly connected at the lower end of the rotating shaft 20; a receiving groove 21 is provided on the upper surface of the first fixed block 11; a torsion spring 19 is fixedly installed on the bottom of the inner cavity of the receiving groove 21; a knob 16 connected to the rotating shaft 20 is fixedly installed on the upper end of the torsion spring 19; the upper surface of the stopper 17 is in contact with the second fixed block 15; the rotating shaft 20 is located inside the torsion spring 19, and the rotating shaft 20 and the knob 16 are connected to form a T-shaped structure.

[0031] During implementation, by turning the knob 16, the torsion spring 19 is elastically deformed, so that the stop block 17 connected by the rotating shaft 20 is separated from the bottom of the second fixed block 15, thereby facilitating the opening of the first bend pipe 7 from the installation groove 13 opened by the second bend pipe 8, making it easier to lay the wires inside the second bend pipe 8, thereby improving installation efficiency.

[0032] During installation of the present technical solution, the wires connected to the female plug shell 5 and the daughter plug shell 3 are first passed through the second bend tube 8 and laid inside the second bend tube 8. Then, the knob 16 is turned to elastically deform the torsion spring 19, so that the stopper 17 connected to it by the rotating shaft 20 is rotated to a certain angle. Then, the first bend tube 7 is covered on the second bend tube 8. At this time, the rotating shaft 20 is located inside the notch 18. Finally, the knob 16 is released. At this time, under the elastic deformation of the torsion spring 19, the stopper 17 is fixed to the inside of the second fixed block 15, so that the upper anti-slip ridge 12 and the lower anti-slip ridge 6 clamp the wire. At the same time, under the action of the first bend tube 7 and the second bend tube 8, the wire is bent in a "Z" shape, thereby preventing the wire from being pulled out and preventing disconnection at the connection position.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may 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 appended claims and their equivalents.
