[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a wire harness shielding protection clamp of the utility model comprises a lower C-shaped plate 1 and an upper C-shaped plate 2, the inner side surface of the lower C-shaped plate 1 is provided with an assembly groove 9 matching the upper C-shaped plate 2, the upper C-shaped plate 2 is movably installed in the assembly groove 9, a fixing portion 5 is protruded on the bottom surface of the lower C-shaped plate 1, a screw hole 10 connected to the assembly groove 9 is provided at the center of the fixing portion 5, a stud 6 for locking and fixing the upper C-shaped plate 2 in the lower C-shaped plate 1 is threadedly connected in the screw hole 10, one end of the stud 6 extends to the outside, and a handwheel 7 is installed, and a fixing ring 8 for connecting to the grounding wire is installed on the bottom surface of the lower C-shaped plate 1.

[0024] In this embodiment, a limiting strip 3 is installed in the opening at one end of the assembly groove 9, one end surface of the upper C-shaped plate 2 is arranged to abut against the bottom surface of the limiting strip 3, and the other end surface of the upper C-shaped plate 2 extends to the outside and bends outward to form a pushing portion 4, and the pushing portion 4 is placed on the opening end surface of the lower C-shaped plate 1.

[0025] In this embodiment, the inner side surface of the lower C-shaped plate 1 is flush with the inner side surface of the upper C-shaped plate 2; the top surface of the limit strip 3 is flush with the open end surface of the lower C-shaped plate 1, so that the upper C-shaped plate and the lower C-shaped plate can be combined together, which greatly reduces the volume, and after the stud contacts the outer ring surface of the upper C-shaped plate, the upper C-shaped plate can be pressed against the lower C-shaped plate, avoiding the upper C-shaped plate from rotating on its own.

[0026] In this embodiment, the outer ring surface of the upper C-shaped plate 2 is arranged in contact with the inner ring surface of the assembly groove 9, so that the upper C-shaped plate can only rotate along the inner side surface of the assembly groove, avoiding swinging and increasing stability.

[0027] In this embodiment, the fixing portion 5 and the stud 6 are eccentrically arranged so that after the stud enters and the assembly is completed, it can be arranged to abut against the end surface of the upper C-shaped plate.

[0028] In this embodiment, a space for fingers to enter is formed between the fixing ring 8 and the hand wheel 7, so that after the fingers grasp the hand wheel, they can smoothly rotate the hand wheel without being blocked by the fixing ring.

[0029] During installation, the wiring harness can be directly placed between the lower C-shaped plate and the upper C-shaped plate. After placement, the upper C-shaped plate can be pulled outward through the push portion, so that the upper C-shaped plate is rotated outward in a ring structure along the inner side of the assembly groove until the push portion abuts against the limit strip. At this time, the hand wheel can be rotated, and the rotation of the hand wheel drives the stud, so that the stud moves upward along the screw hole, so that one end of the stud can enter the assembly groove and abut against the end surface of the upper C-shaped plate away from the push portion. The upper C-shaped plate is tightly abutted against the limit strip by abutting against each other, thereby preventing the upper C-shaped plate from rotating again and increasing stability.

[0030] From the above, it can be known that the lower C-shaped plate and the rotated upper C-shaped plate can wrap the wire harness 360°, increasing the contact area with the wire harness, and no other workpieces are needed, and the installation can be completed by directly turning the hand wheel, which greatly increases the installation efficiency. After the stud is removed from the assembly groove, the upper C-shaped plate can be rotated into the assembly groove again, so that the wire harness can be quickly disassembled, which greatly increases the convenience;

[0031] After the fixation is completed, the grounding wire can be prepared. One end of the grounding wire can be fixed on the fixing ring. The main function of the grounding wire is to effectively conduct the electrostatic charge or electromagnetic interference (EMI) on the wiring harness into the ground, thereby protecting the wiring harness from the influence of electromagnetic interference and preventing the accumulation of electrostatic charge from causing potential safety problems.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
