Description

Technical Field

[0001] The utility model relates to the field of electrical connection, in particular to a novel curved IPT connector. Background Art

[0002] IPT connector is mainly used for the input and output of all-in-one power from the power battery to the rear drive of new energy vehicles, and is installed on one end of the distribution line that is connected to the all-in-one.

[0003] The traditional IPT connector needs to connect the mating copper busbar and the transfer copper busbar at the transfer position, so the shell needs to be provided with a skylight for the disassembled mounting plate and the transfer bolts. The defect is that the skylight structure adds a sealing structure, which not only increases the assembly parts but also increases the risk of sealing failure.

[0004] At the same time, the traditional radially sealed IPT connector relies on the sealing ring to be fixed on the connector housing by the increased elasticity installed on the connector housing. Its defect is that a large amount of compression is required when the sealing requirement is high. At this time, the sealing ring fixed only by elasticity will turn outward when the connector is installed into the cavity, resulting in the connector being unable to be installed into the cavity or the sealing failing after installation.
