AI Technical Summary

Technical Problem

The existing high-voltage cable connectors have limitations in electromagnetic shielding, especially the shielding effect of the shielding claws (titles) method is not ideal, resulting in electromagnetic radiation leakage and signal interference problems.

Method used

Using a cable connection structure including a shielding body, a first compression ring and a second compression ring, the cable is penetrated through the axial receiving cavity, and a shielding layer is clamped with a gap to ensure the shielding layer and the cable. The outer insulation layer is connected to reduce the risk of loosening and deformation and improve electromagnetic shielding performance.

Benefits of technology

It realizes a more reliable connection between the cable and the shielding body, reduces the risk of loosening and deformation of the shielding layer, improves electromagnetic shielding performance and signal transmission stability, and ensures the continuity and integrity of high-voltage cables.

Abstract

The embodiment of the utility model provides a cable connection structure and a vehicle, the cable connection structure comprises a shielding body, a first hold-down ring and a second hold-down ring, the shielding body is internally provided with at least one accommodating cavity penetrating in the axial direction, and the accommodating cavity is used for allowing a cable to penetrate through; a gap is formed between the first hold-down ring and the second hold-down ring, the gap is used for clamping a shielding layer of a cable, one of the first hold-down ring and the second hold-down ring is connected with an outer insulating layer of the cable, and the other one of the first hold-down ring and the second hold-down ring abuts against the shielding body. Therefore, reliable connection between the cable and the shielding body can be realized by using the first hold-down ring and the second hold-down ring. And moreover, the shielding layer is clamped between the first pressing ring and the second pressing ring, so that the risks of loosening and deformation of the shielding layer are reduced, the continuity and integrity of the shielding layer are ensured, and the electromagnetic shielding performance of the cable can be improved.
