Self-cooling type conductive contact piece and connector

Abstract

The present invention relates to a self-cooling type conductive contact piece and a connector. The connector comprises a connector housing and a self-cooling type conductive contact piece arranged in the connector housing; the self-cooling type conductive contact piece comprises a contact piece body; a liquid flow channel in which a cooling liquid circulates to make heat on a contact piece body discharged with the cooling liquid is arranged in the contact piece body; and two ends of the liquid flow channel are provided with a liquid inlet and a liquid outlet respectively. The liquid flow channel is arranged in the self-cooling type conductive contact piece; the insulating cooling liquid can directly flow into the liquid flow channel; the cooling liquid enters the contact piece from the liquid inlet and then circulates in the contact piece; in the circulation process, the cooling liquid takes away the heat on the contact piece, flows out through the liquid outlet and cools outside; and therefore, circulatory heat exchange can be realized, and heat conduction and heat dissipation of the contact piece can be realized. The flow rate of the cooling liquid can be adjusted according to the amount of the heat emitted by the contact piece, and therefore, the contact piece can be well cooled under the premise that current passing through the contact piece is not decreased.

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.
