Problems solved by technology

[0003] The existing high-voltage and high-current connectors do not monitor the temperature of the connector itself. During the vibration process of the connector, the temperature of the contact part is likely to rise sharply due to poor contact, coating wear, etc., and eventually the high-voltage line is caused by thermal runaway. Phenomena such as ablation

Abstract

According to a high-voltage connector, a storage groove is formed on the side face of a jack, and the top and the inner side of the storage groove are both open; a second threading hole is formed on the bottom surface of the interior of the storage groove, a temperature detection element is embedded into the storage groove, is embedded into the storage groove and is electrically connected with a wire, the wire penetrates through the second threading hole, and the temperature detection element is used for monitoring the internal temperature of the connector. According to the invention, the temperature detection element is installed inside the connector, the temperature change inside the conductive copper bar and the whole connector can be detected in real time, and when the temperature is too high, the alarm information is transmitted to a vehicle driver, so that a vehicle fire phenomenon caused by the too high temperature is effectively avoided, and the safety of a whole high-voltage loop is improved.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, in particular to a high-voltage connector. Background technique [0002] High-voltage connectors are widely used in various fields, especially in the new energy vehicle industry. Connectors are important components in the entire high-voltage system; The demand for connectors is increasing, especially for logistics vehicles and electric buses. The total output current of the power battery can reach about 300A. The high heat generated by the transmission of large currents is directly related to the safety of the entire vehicle. [0003] The existing high-voltage and high-current connectors do not monitor the temperature of the connector itself. During the vibration process of the connector, the temperature of the contact part is likely to rise sharply due to poor contact, coating wear, etc., and eventually the high-voltage line is caused by thermal runaway. erosion etc. Contents of...
