Abstract: A joint structure of a high-voltage cable includes a cable core wrapped from interior to exterior sequentially by an inner insulating layer, a shielding layer and an outer insulating layer, a section of the inner and outer insulating layers is stripped at an end of the cable core, and a length of the stripped section of the outer insulating layer is greater than a length of the stripped section of the inner insulating layer. The end of the cable core is connected to an external terminal, a connection between the end and the external terminal and an adjacent section of the inner insulating layer are wrapped by a heat-shrinkable tube, a spacing is provided between an end of the heat-shrinkable tube and the outer insulating layer, the shielding layer within the spacing is wrapped by a copper foil and connected externally to a cable connector via the copper foil.
