Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-5As shown, this utility model provides a technical solution: an environmentally friendly insulated automotive wiring harness, including a connector 1, a wire 2 fixedly connected to one side of the connector 1, a fixing seat 3 provided on the outer surface of the wire 2, a fixing structure 4 movably connected to one side of the fixing seat 3, the wire 2 including a conductor core 21, the outer surface of the conductor core 21 being wrapped with an environmentally friendly insulation layer 22, the outer surface of the environmentally friendly insulation layer 22 being wrapped with a shielding layer 23, and the outer surface of the shielding layer 23 being wrapped with a flame-retardant protective layer 24, the fixing seat 3 including a fixing block 31, a fixing groove 32 formed on the outer surface of the fixing block 31, a connecting groove 33 formed on one side of the fixing groove 32, the fixing structure 4 including a pressure plate 41, a spring 42 fixedly connected to the top of the pressure plate 41, the top of the spring 42 being fixedly connected to the inner wall of the fixing groove 32, a pressure block 43 fixedly connected to the bottom of the pressure plate 41, and a connecting groove 33 formed on one side of the pressure plate 41. A connecting rod 44 is fixedly connected to the side, and the outer surface of the connecting rod 44 is slidably connected to the inner wall of the connecting groove 33. A support plate 34 is fixedly connected to the inner wall of the fixing block 31, and a slot 35 is opened on the outer surface of the support plate 34. An extension plate 45 is fixedly connected to one side of the connecting rod 44, and a support column is fixedly connected to the outer surface of the extension plate 45. A baffle 46 is fixedly connected to the outer surface of the support column. A rotating knob 47 is provided on one side of the baffle 46, and the inner wall of the rotating knob 47 is rotatably connected to the outer surface of the support column. A rotating locking strip 48 is fixedly connected to one side of the rotating knob 47, and the outer surface of the rotating locking strip 48 is engaged with the inner wall of the slot 35. The conductor core 21 is made of multiple strands of copper wire twisted together. The environmentally friendly insulation layer 22 is made of environmentally friendly polyvinyl chloride material. The shielding layer 23 is made of copper wire braiding. The flame-retardant protective layer 24 is made of halogen-free flame-retardant polyolefin material.

[0028] In this embodiment, by setting a support plate 34 and a slot 35, when the slot 35 and the rotating clip 48 are engaged, the extension plate 45, the pressure plate 41 and the connecting rod 44 are temporarily fixed, thereby enlarging the entrance for clamping the wire 2, which facilitates clamping and fixing the wire 2. The rotating clip 48 is engaged with the slot 35 by rotating the knob 47 on the surface of the support column. By setting the connecting rod 44 to pass through the connecting groove 33, the pressure plates 41 in a row can be connected together. By controlling the extension plate 45, the pressure plates 41 and the pressure blocks 43 in a row can be lifted upwards simultaneously, so that it is not necessary to lift the pressure plates 41 and the pressure blocks 43 in each fixing groove 32 upwards.

[0029] In addition, when the extension plate 45 is moved upward, the rotating knob 47 will also move upward, and its surface will stick to one side of the support plate 34. At this time, rotating the rotating knob 47 can rotate the rotating clip 48 into the slot 35.

[0030] The environmentally friendly insulation layer 22 in the conductor 2 uses environmentally friendly polyvinyl chloride material that does not contain harmful substances and will not cause pollution to the environment during production and use. At the same time, it has good insulation properties and can effectively prevent leakage of conductor core 21. The flame-retardant protective layer 24 is made of halogen-free flame-retardant polyolefin material, which has excellent flame-retardant properties and can effectively prevent the spread of fire in the event of a fire, thereby improving the safety of the vehicle.

[0031] Working principle:

[0032] like Figure 1-5 As shown, when actually installing and using this environmentally friendly insulated automotive wiring harness, first pull the extension plate 45 upward, causing the connecting rod 44 to slide upward along the connecting groove 33, thereby causing the pressure plate 41 to compress the spring 42 and move upward, and the pressure block 43 to be lifted accordingly. Rotate the rotating knob 47 to make the rotating clip 48 engage with the clip groove 35, providing sufficient space for the wire 2 to be placed, and pass the wire 2 through the fixing groove 32 on the fixing seat 3.

[0033] Once the conductor 2 is in place, rotate the knob 47 to disengage the rotating clip 48 from the slot 35. Under the elastic reset action of the spring 42, the pressure plate 41 drives the pressure block 43 to move downward and press firmly against the outer surface of the conductor 2, thus achieving a stable fixation of the conductor 2. The environmentally friendly insulation layer 22 provides insulation protection for the conductor core 21, and the flame-retardant protective layer 24, made of halogen-free flame-retardant polyolefin material, has excellent flame-retardant properties.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
