Description

Technical Field

[0001] This application relates to the photovoltaic field, and more particularly to cable assemblies and photovoltaic systems. Background Technology

[0002] During the installation of a photovoltaic system, cables need to be connected to the enclosure that houses the equipment (e.g., an inverter) via connectors and conductive plugs.

[0003] Due to the complex environment at the installation site and the instability of human operation, the various components are installed separately, which often leads to the loss of components or the inability of cables to be accurately connected to the chassis, resulting in low efficiency in cable and chassis installation.

[0021] During the installation of a photovoltaic system, cables need to be connected to the enclosure that houses the equipment (e.g., an inverter) via connectors and conductive plugs.

[0022] Specifically, the installer first inserts the connection terminal into the mounting position of the chassis, then uses the locking device inside the chassis to lock the connection terminal, then inserts the conductive plug into the connection terminal, and finally inserts the cable into the conductive plug.

[0023] Due to the complex environment at the installation site and the instability of human operation, the various components are installed separately, which often leads to the loss of components or the inability of cables to be accurately connected to the chassis, resulting in low installation efficiency.

[0024] To address the above problems, this utility model provides a cable assembly. Figure 1 This is a structural schematic diagram of a cable assembly provided by the present invention, as shown below. Figure 1 As shown, the cable 103 assembly 10 includes:

[0025] The connection terminal 101 includes a first portion 1011 and a second portion 1012 connected to the first portion 1011. After the connection terminal 101 is connected to the mounting part of the chassis, the first portion 1011 is located on one side of the mounting part, and the second portion 1012 is located on the other side of the mounting part. A conductive plug 102 is connected to the second portion 1012. A cable 103 is connected to the conductive plug 102.

[0026] It should be noted that, for ease of understanding, Figure 1 The illustration shows the connection terminal 101 and the conductive plug 102 not connected. In reality, after the cable assembly 103 is manufactured, the connection terminal 101 and the conductive plug 102 are connected.

[0027] The mounting part can be a hole on the chassis, or it can be other devices on the chassis. This utility model does not impose any specific limitations on this.

[0028] The material of the connecting terminal 101 can be plastic or ceramic. Of course, the connecting terminal 101 can also be made of other materials. This utility model does not impose specific restrictions on this.

[0029] like Figure 1 As shown, the second part 1012 is provided with a fastening device 104, which is used to fix the connecting terminal 101 to the chassis.

[0030] The fastening device 104 can be a nut. Of course, the fastening device 104 can also have other structures. This utility model does not impose specific limitations on this.

[0031] The fastening device 104 can be made of plastic or ceramic. Of course, the fastening device 104 can also be made of other materials. This utility model does not impose any specific restrictions on this.

[0032] The part where the chassis connects to the connection terminal 101 may be provided with a device that cooperates with the fastening device 104.

[0033] like Figure 1 As shown, the conductive plug 102 has a limiting latch 1021, which is used to fix the conductive plug 102 to the connecting terminal 101. In this way, the stability of the connection between the conductive plug 102 and the connecting terminal 101 can be increased.

[0034] The number of limit buckles 1021 can be one or more, and this utility model does not impose a specific limitation on this.

[0035] The cable 103 can be soldered to the conductive plug 102, or the cable 103 can be crimped to the conductive plug 102. Of course, the cable 103 can also be connected to the conductive plug 102 in other ways. This utility model does not impose any specific limitations on this.

[0036] Based on this solution, compared with the existing solution where the connection terminal 101 is first inserted into the mounting part of the chassis, the connection terminal 101 is locked inside the chassis, then the conductive plug 102 is inserted into the connection terminal 101, and then the cable 103 is inserted into the conductive plug 102, in this utility model solution, the cable 103 assembly 10 includes: a connection terminal 101, including a first part 1011 and a second part 1012 connected to the first part 1011. After the connection terminal 101 is connected to the mounting part of the chassis, the first part 1011 is located on one side of the mounting part, and the second part 1012 is located on the other side of the mounting part; the second part... The second part 1012 is equipped with a fastening device 104, which is used to fix the connecting terminal 101 to the chassis. The second part 1012 is also equipped with a conductive plug 102 and a cable 103 connected to the conductive plug 102. Therefore, the connecting terminal 101, the fastening device 104, the conductive plug 102 and the cable 103 can be installed as a whole. During installation, the connecting terminal 101 is inserted into the mounting part of the chassis, and then the connecting terminal 101 can be locked by the fastening device 104 on the connecting terminal 101. This eliminates the need for installers to install each component in turn, thereby improving the efficiency of the cable 103 and chassis installation.

[0037] This utility model also provides a photovoltaic system, which includes: a chassis for housing photovoltaic equipment, the chassis including a mounting part; and the aforementioned connection terminal 101, which is connected to the mounting part of the chassis. The photovoltaic equipment can be an inverter, rectifier, or other similar devices, and this utility model does not impose specific limitations on this.

[0038] In this embodiment, the photovoltaic system can be applied in photovoltaic power plants, such as ground-mounted power plants, rooftop power plants, and floating power plants. It can also be applied to equipment or devices that utilize solar energy to generate electricity, such as user solar power supplies, solar streetlights, solar cars, and solar buildings. Of course, it is understood that the application scenarios of the photovoltaic system are not limited to these; that is, the photovoltaic system can be applied in all fields that require solar energy to generate electricity. Taking a photovoltaic power generation system network as an example, the photovoltaic system may include a photovoltaic array, a combiner box, and an inverter. The photovoltaic array may be an array combination of multiple battery modules; for example, multiple battery modules can form multiple photovoltaic arrays. The photovoltaic array is connected to the combiner box, which can collect the current generated by the photovoltaic array. The collected current flows through the inverter and is converted into AC power required by the mains power grid before being connected to the mains power grid to achieve solar power supply.
