Liquid-cooled cable connecting assembly and connector

Abstract

The invention discloses a liquid-cooled cable connecting assembly and a connector. The liquid-cooled cable connecting assembly comprises liquid-cooled cable connectors. Each liquid-cooled cable connector comprises a cable tail terminal, a pin terminal and a cable, wherein the cable tail terminal is provided with a first accommodating cavity with one end opened and a first liquid flowing channel communicated with the first accommodating cavity; the pin terminal is provided with a second accommodating cavity with one end opened and a second liquid flowing channel communicated with the second accommodating cavity; the cable comprises an insulating pipe and a conductor located inside the insulating pipe, two ends of the insulating pipe are respectively in sealed connection with the opened endsof the first accommodating cavity and the second accommodating cavity, two ends of the conductor extend to be inserted in the first accommodating cavity and the second accommodating cavity and are contacted with the cable tail terminal and the pin terminal respectively, and liquid flowing gaps are formed among the conductor and the first accommodating cavity, the second accommodating cavity and the inner wall of the insulating pipe. The liquid-cooled cable connecting assembly is simple in structure and convenient in operation, conduction of a coolant can be realized while electric connectionis ensured, and temperature rise of a contact piece at a heat source place can thus be controlled.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a liquid-cooled cable plug assembly and a connector. Background technique [0002] Connectors are widely used in various fields, especially in the new energy vehicle industry, where connectors are extremely important components. In the application of new energy vehicles, pins, terminals, and charging cables are contacts with high heating temperature in electric vehicle charging connectors. These contacts tend to generate heat due to long-term work in a high-current and high-voltage environment. serious. In particular, the contacts heat up due to the existence of their own resistance when conducting current, and the general connector has a high protection level, and the contacts work in a closed environment with poor heat dissipation conditions. Working in a high-temperature environment for a long time will easily accelerate the aging of the contacts, and the connector insula...

Problems solved by technology

In particular, the contacts heat up due to the existence of their own resistance when conducting current, and the general connector has a high protection level, and the contacts work in a closed environment with poor heat dissipation conditions

Working in a high temperature environment for a long time, it is easy to accelerate the aging of the contacts, and the connector insulator and shell are also affected by aging to varying degrees

How to reduce the temperature rise of the connector has always been a technical problem. Existing methods often start with improving the performance of the contact or improving the heat dissipation structure of the housing, but the improvement is difficult, costly, and the effect is not significant
