Abstract

The invention relates to a connector with thermal protection function. The thermal protection connector includes an insulating body, a terminal group, and a thermal protection unit. A plugging space is formed at the front end of the insulating body. The terminal group is arranged through the insulating body. The terminal group includes at least two power terminals. Each power terminal has an electrical contact section, a welding section and an extension section. The electrical contact section protrudes into the insertion space, and the welding The segment is connected to a circuit board, and the extension segment protrudes backward from the soldering segment. The thermal protection unit includes a thermal action element and a thermal protection element. The heated action element is arranged on the circuit board, the heat protection element covers the heat action element, and the extension section penetrates the heat protection element and is attached to the heat action element, so that the heat action element can move more quickly and avoid the insulation body more quickly There are cases of burning and blackening of terminals.

Description

technical field [0001] The invention relates to a connector, in particular to a connector with thermal protection function. Background technique [0002] The plug connector of the USB Type-C interface specification can be used to dock with the socket connector of the USB Type-C interface specification for power transmission. When liquid, such as soda, sports drinks, etc., accidentally infiltrates into the insertion space of the connector, it is easy to cause a short circuit (micro-short circuit) between the terminals and generate high temperature, causing the connector to burn and the terminals to burn. In order to avoid the aforementioned situation, a PTC (Thermistor) is usually provided on the circuit board of the connector. However, the high temperature is slowly transmitted to the PTC through the terminals and the circuit board. Therefore, when the PTC is slowly heated to the switching temperature, the connector may have been burned and the terminals have been scorched....
