Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to a connector sealing structure. Background Art

[0002] There is still no good solution to the problem of water and air leakage when the existing automotive connectors are integrally injection molded with the connector body and the cable insert. There are currently two common methods to save sealing. One is to make the terminal into a special-shaped bend, and to improve the sealing effect by extending the embedding interface between the insert and the plastic. However, this method still has an interface gap formed by the different thermal expansion coefficients of the two materials, and there is still a sealing problem over time. The other is to make the insert into two connectors and add a sealing ring at the connection. This sealing structure has a good sealing effect, but the manufacturing cost is relatively high.
