Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grounding devices, and in particular relates to a cable ring grounding device. Background Art
[0002] Among the many tests in the automotive electronics laboratory, some tests require that the high-voltage cable be passed directly from the shielding body through the waveguide into the laboratory. The cable needs to be grounded to the shielding body. The traditional method is generally to use copper foil to overlap the cable surface shielding layer and the shielding body. It is difficult to completely overlap the high-voltage cable and the shielding body for grounding. Once this test is not performed, the high-voltage cable needs to be pulled out of the laboratory. It takes a long time to peel off the original copper foil and the residual adhesive of the copper foil is difficult to clean, which affects the appearance of the laboratory. Utility Model Content

[0006] The cable shielding sleeve comprises a fixing plate, the fixing plate is connected to a pipe sleeve located inside the straight-through pipe, and the other end of the fixing plate is evenly and annularly mounted with a plurality of clips, the clips having an inclination;
[0007] The male head of the grounding clamp is threadedly connected with an inner cylinder whose position matches that of the clamp, and the male head of the grounding clamp and the female head of the grounding clamp are provided with screw holes whose positions correspond to each other.

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a cable ring grounding device of the utility model comprises a straight-through pipe 1, a fixing ring 2 is installed on the outer side of the straight-through pipe 1, a grounding clamp female head 3 is threadedly connected to the end of the straight-through pipe 1, a grounding clamp female head 3 is matched with a grounding clamp male head 4, and a cable shielding sleeve 5 is clamped and installed between the grounding clamp female head 3 and the grounding clamp male head 4;
[0022] The cable shielding sleeve 5 includes a fixing plate 51, the fixing plate 51 is connected to a pipe sleeve 52 located inside the straight-through pipe 1, and the other end of the fixing plate 51 is evenly and annularly mounted with a plurality of clips 53, and the clips 53 have an inclination;
[0023] The male grounding clamp 4 is threadedly connected with an inner tube 6 of the position matching clamp 53, and the male grounding clamp 4 and the female grounding clamp 3 are provided with screw holes 7 with corresponding positions.
[0024] In this embodiment, when using a cable ring grounding device, the fixing ring 2 is installed on the shielding body, and then it can be used;
[0025] When not in use, the grounding clamp female connector 3 may not be installed, and the end of the straight-through pipe 1 may be blocked to ensure the appearance of the laboratory;
[0026] When in use, the grounding clamp female head 3 is installed at the end of the straight pipe 1 in a threaded connection manner, and then the pipe sleeve 52 of the cable shielding sleeve 5 is inserted into the straight pipe 1 until the fixing piece 51 contacts the end face of the grounding clamp female head 3, the high-voltage cable is passed through the position of the clip 53, and then the grounding clamp male head 4 is locked on the grounding clamp female head 3 through the screw hole 7. In this action, the inner tube 6 will squeeze the inclined clip 53, thereby achieving the purpose of locking the high-voltage cable;
[0027] Furthermore, by replacing the inner tube 6 with different sizes, different degrees of squeezing effect on the clip 53 can be achieved, that is, the inner diameter size of the clip 53 after being squeezed is changed to adapt to the clamping and fixing of high-voltage cables with different diameters.
[0028] Preferably, the fixing ring 2 is provided with a fixing hole 21. With this design, the fixing ring 2 can be fixed by using screws in conjunction with the fixing hole 21. In fact, the fixing method of the fixing ring 2 can also be considered according to specific circumstances.
[0029] Preferably, the straight-through pipe 1 is threadedly connected with a cover. With this design, when it is idle, the grounding clamp female head 3 can be removed and the straight-through pipe 1 can be sealed with the cover. In fact, the installation method of the cover can also be considered according to the specific situation.
