Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted terminals, in particular to a waterproof structure of a terminal and a vehicle-mounted terminal. Background Art

[0002] Most of the terminals on the market do not have waterproof measures, especially at the connector position. Due to the higher requirements for the use environment of some car manufacturers, the protection level of the terminal is further required, so it is necessary to make a waterproof design at the terminal connector position. In order to solve the waterproof problem of the terminal connector, the Chinese utility model with application number 202223328408.0 discloses a vehicle-mounted controller, including a first shell, a second shell, a connector and a seal. The first shell and the second shell cover each other and form an installation chamber with an installation port with a ring-shaped inner wall with the first shell. The connector is arranged at the installation port and has an annular side wall. The seal is sleeved on the periphery of the side wall of the connector, one side of the seal is in contact with the side wall of the connector, and the other side is in contact with the inner wall of the installation port. Although this structure can solve the waterproof problem of the terminal connector, it is necessary to adapt the shape of the installation port to the connector. If the same type of product is replaced with a different connector, the first shell and the second shell also need to be replaced and the mold is re-opened, which greatly increases the manufacturing cost.
