Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a cable for solar photovoltaic components. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center, with a highly insulating covering layer on the entire outside. The cable has the characteristics of being powered inside and insulated outside. The existing cable for solar photovoltaic modules needs to be adjusted in length as needed. Therefore, when two cables need to be connected, usually, the staff connects the cable cores and then uses insulating tape to stick and wrap the outer insulating layer to connect the two cables so that the data signal can be transmitted from one cable to another. However, since the focus of the two cables is on the insulating tape that adheres the insulating layers of the two cables, when the cables are in a humid and high temperature environment, the insulating tape is prone to degumming, causing the insulating layers of the two cables to come off, and eventually causing the two cables to come off, which may cause moisture to enter from the connection, causing damage.

[0003] In order to solve the above problems, patent number CN202321646996.4 discloses a cable for solar photovoltaic components, which is provided with springs, clamping columns and toggle plates. By manually toggling the two toggle plates, four springs are compressed to drive the two clamping columns to move to the left. When fixed, by releasing the two toggle plates, the elastic force of the springs is used to reset the two clamping columns to be clamped in the corresponding two fixed cylinders, so that the two first cables and the second cables can be quickly connected. By rotating the upper and lower rotating handles respectively, the two threaded rods are driven to rotate, and then the two clamping blocks are driven to approach the two clamping columns until the two clamping blocks are clamped in the two fixed grooves, so that the first cable and the second cable are fixedly connected; by providing a first placement shell, a second placement shell, a sealing ring, a plug rod and a socket, when installing, the two plug rods at the left end of the first sleeve are aligned with the two sockets at the right end of the second sleeve, and the sealing ring in the first placement shell is clamped in the second placement shell. At this time, the two plug rods are clamped and fixed in the two sockets, so that the connection between the first cable and the second cable is sealed to prevent water vapor from entering the internal connection.

[0004] The solar photovoltaic assembly cable disclosed in the above patent is connected by two closed sleeves, which is not convenient to open and cannot ensure that the wire cores are neatly and firmly connected together, and the sleeves are easy to slide along the outside of the cable.

The cables for solar photovoltaic components disclosed in the utility model can be connected through a quick wiring assembly, and the quick wiring assembly is composed of an upper clamp and a lower clamp, and can be open-designed for easy docking of cable cores. A plurality of metal limiting spikes are installed at both ends of the inner side wall of the quick wiring assembly, which can be firmly inserted into the cable sleeve, with good limiting effect. After docking, the quick wiring assembly is not easy to move, so as to solve the problems raised in the above-mentioned background technology.
