When in use, the internal wires are arranged in a line in the outer sheath, which increases the minimum margin of the injection molding and the rubber coating, thereby greatly improving the product qualification rate."

[0004] However, one type of wiring harness in the above-mentioned public document mainly considers improving the product qualification rate, but is not convenient for protecting the outside of the safety photovoltaic wiring harness. Because the wiring harness body is installed in an electrical box, and most electrical boxes cannot be completely closed, air containing water vapor and dust enters the electrical box, and the water vapor in the air will corrode the outside of the wiring harness body. At the same time, the friction of the wiring harness body by external objects will also cause damage to the outside of the wiring harness body, thereby reducing the safety of the wiring harness body.

[0005] In view of this, it is necessary to develop a protection mechanism to protect the outside of the safety photovoltaic wiring harness. Utility Model Content

[0016] 1. The utility model protects the wiring harness body by installing a protection mechanism to prevent external factors from causing damage to the outside of the wiring harness body and reducing the safety of the wiring harness body. The wiring harness body is installed in an electrical box, and most electrical boxes cannot be completely closed, which causes air with water vapor and dust to enter the electrical box and the water vapor in the air will corrode the outside of the wiring harness body. At the same time, the friction of the wiring harness body by external objects will also cause the outside of the wiring harness body to be damaged, which reduces the safety of the wiring harness body. Therefore, it is necessary to protect the outside of the wiring harness body to prevent the outside of the wiring harness body from being damaged by external influences. In order to affect the safety of the wiring harness body, first pull the push rod to move the push rod in the fixing ring, then move the sealing block, move the transparent protective shell to the outside of the wiring harness body, then fix the first threaded rod to the first threaded groove, then install the transparent protective shell on the outside of the wiring harness body, then push the push rod to move the sealing block to seal the gap between the transparent protective shell and the wiring harness body, then fix the second threaded rod to the second threaded groove to fix the position of the sealing block, then protect the outside of the wiring harness body, and prevent external factors from causing damage to the outside of the wiring harness body and reducing the safety of the wiring harness body;

[0017] 2. The utility model is equipped with a display mechanism to distinguish different types of photovoltaic wiring harnesses. There are many wires in the electrical box, which makes it difficult for staff to quickly distinguish the names and corresponding functions of each wire when they inspect the wires in the electrical box. Therefore, the wiring harness body needs to have a display function so that staff can see the threaded light on the wiring harness body and recognize that the wire is the wiring harness body at a glance, which is convenient for staff to inspect later. The second Velcro is adhered to the first Velcro, and the bracket is installed on the wiring harness body. The wiring harness body is installed in the electrical box and powered on. When the threaded light is on, the wiring harness body can be distinguished from other wires. At the same time, the threaded light can be changed to other conspicuous colors. The threaded light can be removed from the screw hole by twisting it, and the threaded light can be disassembled and replaced. Therefore, the wiring harness body has a display function so that staff can see the threaded light on the wiring harness body and recognize that the wire is the wiring harness body at a glance.
