Description

Technical Field

[0001] The utility model relates to the technical field of wire harness shielding covers, in particular to a signal wire harness shielding cover. Background Art

[0002] Shielding covers are tools used to shield electronic signals. Shielding covers are mostly made of metal. Their function is to shield the influence of external electromagnetic waves on internal wiring harness circuits, prevent the electromagnetic waves generated internally from radiating outward, and shield the outside of the signal harness to prevent the harness from being exposed to external collisions and impacts and being damaged. In recent years, new energy vehicles have gradually become popular. In order to ensure the normal operation of new energy vehicles, complex signal harnesses are installed inside new energy vehicles. In order to improve the working stability of the signal harness, a shielding cover is required to be installed on the outside of the key signal harness.

[0003] Traditional signal harness shielding covers mostly adopt a square shell structure. Since the shielding covers are processed by a bending process, the square shell shielding covers have more bending seams, and more welding points are required during processing. In addition, the square shell shielding covers have poor protection against lateral impacts. When hit, the internal wiring harness is easily damaged. In addition, traditional wiring harness shielding covers lack a restraining and limiting structure for the internal wiring harness. When the car is running, the wiring harness is prone to slippage and friction inside the shielding cover, which can easily cause the surface of the wiring harness to wear and crack over a long period of time, posing certain safety hazards.

[0026] As attached Figure 4 As shown, the protective top plate 2 and the protective side plate 3 are respectively connected to the front and rear sides of the shielding plate 1, and are respectively located at the top and front sides of the shielding cover body after being bent. The protective end plate 4 is connected to the side of the protective side plate 3, as shown in the attached Figure 4As shown, the protective end plate 4 is located on the end side of the shielding cover body, and the protective end plate 4 is welded to the sides of the shielding plate 1, the protective top plate 2, and the protective side plate 3. The shielding cover is bent as a whole and welded to the protective end plate 4 on the end side. The welds are required to be full and the weld diameter must not be less than 2mm. The welds are concentrated on the end side of the shielding cover. The welding process is more convenient and the number of welds can be reduced, which is beneficial to the shielding cover processing operation.

[0027] In order to improve the side impact resistance of the shielding cover body, Figure 2 As shown, after bending, the shielding plate 1 is tilted and arranged on the upper part of the shielding cover body, forming a stress-bearing folding surface on the side, which greatly improves the lateral impact resistance of the shielding cover, and a fixed side seat 6 is arranged at the stress-bearing position in the middle of the shielding plate 1, which can further improve the structural strength of the shielding cover.

[0028] As attached Figure 4 As shown, the fixed end seat 5 is arranged on the side of the protective end plate 4.

The shielding cover is bent as a whole and welded and fixed to the protective end plate 4 on the end side. The welding points are concentrated on the end side of the shielding cover. The welding process is more convenient and the number of welding points can be reduced, which is beneficial to the shielding cover processing operation. The shielding plate 1 adopts an inclined structure setting to form a force-bearing folding surface on the side, which greatly improves the lateral impact resistance of the shielding cover. A fixed side seat 6 is provided at the force-bearing position in the middle of the shielding plate 1, which can further improve the structural strength of the shielding cover. A wiring harness fixing strap 11 is provided on the upper part of the protective side plate 7. The wiring harness fixing strap 11 can be used to constrain and limit the wiring harness in the shielding cover, which can effectively prevent the wiring harness from being damaged due to sliding friction, thereby greatly improving the safety and protection of the shielding cover.
