JOINT STRUCTURE FOR HIGH-VOLTAGE CABLE

The present disclosure discloses a joint structure of a high-voltage cable, including a cable core (7), the cable core (7) being wrapped from interior to exterior sequentially by an inner insulating layer (6), a shielding layer (8) and an outer insulating layer (5), a section of the inner insulating layer (6) and of the outer insulating layer (5) being stripped at an end of the cable core (7), and a length of the stripped section of the outer insulating layer (5) being greater than a length of the stripped section of the inner insulating layer (6), wherein the end of the cable core (7) is connected to an external terminal (9), a connection between the end of the cable core (7) and the external terminal (9) and an adjacent section of the inner insulating layer (6) are wrapped by a heat-shrinkable tube, a spacing is provided between an end of the heat-shrinkable tube and the outer insulating layer (5), the shielding layer (8) within the spacing is wrapped by a copper foil, and the shielding layer (8) is connected externally to a cable connector via the copper foil. The present disclosure improves the safety during connecting the cable connector to the high-voltage cable, can avoid a too large diameter at the tail end of the high-voltage cable, and can prevent the shielding layer (8) from being scraped by the cable connector to be damaged.
