Problems solved by technology
like Figure 7 In the middle, if the cable is always in the open state, the two wires at the left end will cause a short circuit after being exposed to water, which may cause damage to the power supply
[0004] Some existing technologies control circuit on and off through computer programs and circuit boards, resulting in high cost and difficult implementation
[0005] Existing high-voltage cables generate a lot of heat during charging, and it is difficult for cables to achieve rapid heat dissipation
In order to achieve heat dissipation, some cables need to add more heat dissipation medium, resulting in complicated cable structure

The invention relates to a safety component for a cable of a new energy automobile. The safety component comprises a first connecting block and a second connecting block; the right end surface of thefirst connecting block is provided with a first connecting hole and a second connecting hole, and the left end surface of the second connecting block is provided with a first connecting piece and a second connecting piece; the right end of the first connecting block is provided with a first isolation cover, and the left end of the second connecting block is provided with a second isolation cover;and the positions of the first isolation cover and the second isolation cover are oppositely arranged, and the opposite surfaces of the first isolation cover and the second isolation cover are both provided with openings. The beneficial effects are as follows: automatic power failure can be realized when a charging power supply is not connected, and thus the problem of damages to an automobile power supply caused by short circuit of a charging interface can be effectively prevented; when a charging cable is connected to the charging power supply, the circuit path connection can be automatically realized, and the charging operation is further carried out; the cable has better heat dissipation performance; and compared with common cables, the cable can export heat more quickly.
Description
technical field [0001] The invention belongs to the field of automobile manufacturing industry, and in particular relates to a high-voltage cable for automobiles. Background technique [0002] With the vigorous development of the automobile industry, high-performance cables for automobiles have been put on the agenda. Due to the large increase in electronic devices in automobiles, the requirements for the size of electronic devices in automobiles are getting higher. On the one hand, the cables are required to be as flexible as possible for easy placement. Or bundling, on the other hand requires high security of the cables. [0003] Generally, the voltage is relatively high during the charging process of a car, and some high-voltage cables are required. Existing high-voltage cables for car charging can only simply realize the charging function. Since they are directly connected to the power supply, a short circuit will occur if the charging port is wading through water. Suc...
