Problems solved by technology

However, with the emergence of various high-current electronic devices, the charging current is getting larger and larger, the charging times are becoming more and more frequent, and the number of plugging and unplugging of various connecting wire interfaces is also increasing. The electronic equipment connected with each other may have the hidden danger of being burned due to the inability to withstand a large fault current and heat
At present, various connection lines have not adopted effective protection methods to deal with this hidden danger, so once a failure occurs, it will lead to serious consequences

Abstract

The invention discloses a charging interface for overcurrent or overheating protection. The charging interface includes a base and a conductive part, wherein the conductive part is fixed in the base; an overcurrent and overheating protection element is electrically connected in series with the conductive part; the conductive part comprises a first conductive part and a second conductive part at least, wherein the first conductive part is composed of a first embedded end and a first connection end, and the first embedded end is not in direct contact with the first connection end; the first embedded end is fixed in the base and is electrically connected in series with the first connection end through the overcurrent and overheating protection element; the second conductive part is an integral conductive part formed by electrically connecting a second embedding end with a second connection end directly. The charging interface can cut off the current promptly until the fault is removed when the current is abnormal and the interface temperature is too high, so that the charging interface has outstanding safety performance.

Description

technical field [0001] The invention relates to a charging interface for overcurrent and overheating protection. In particular, when the current is abnormal and the temperature of the interface is too high, the charging interface can cut off the current in time until the fault is resolved, so it has outstanding safety performance. Background technique [0002] With the development of various peripheral electronic devices using data transmission and charging interfaces, people use various connection lines more and more frequently in daily life. However, with the emergence of various high-current electronic devices, the charging current is getting larger and larger, the charging times are becoming more and more frequent, and the number of plugging and unplugging of various connecting wire interfaces is also increasing. The electronic equipment connected with each other may have the hidden danger of being burned due to the inability to withstand a large fault current and heat. ...
