A self-cooling conductive contact piece and connector

Abstract

The invention relates to a self-cooling conductive contact piece and a connector. The connector includes a connector housing and a self-cooling conductive contact provided in the connector housing. The self-cooling conductive contact includes a contact body, and the inside of the contact body is provided with a coolant for circulation to make the contact body The heat on the surface is exported along with the liquid flow channel of the cooling liquid, and the two ends of the liquid flow channel are respectively provided with a liquid inlet and a liquid outlet. The self-cooling conductive contact has a liquid flow channel inside it, and can directly pass into the insulating cooling liquid. The cooling liquid enters the contact from the liquid inlet and circulates inside the contact. The heat is absorbed, and then flows out from the liquid outlet and cooled externally to realize cyclic heat exchange and heat conduction and heat dissipation to the contact parts. Good cooling of the contacts is achieved under the premise of current passing through the contacts.

Description

technical field [0001] The invention relates to a self-cooling conductive contact piece and a connector. Background technique [0002] The conductive contact will generate a certain amount of heat due to the existence of resistance when the current passes, resulting in the temperature rise of the contact. In order to solve the problem of temperature rise of the contact, it is usually achieved by controlling the magnitude of the current, that is, when the contact When the heat is too large, the temperature rise of the contact can be reduced by reducing the current. When the temperature is too high, it is even necessary to stop the current input, and then conduct the current input after the contact is cooled, which makes the contact impossible. Long-term continuous use, or the passing current cannot pass through a large current for a long time, which will affect the normal use of the contacts and affect the work efficiency.
