Sealed electric connector for transmitting high-speed radio frequency or differential signals on vehicle

Abstract

The invention relates to a sealed electric connector for transmitting high-speed radio frequency or differential signals on a vehicle, which comprises a first connector and a second connector, wherein waterproof sealing between the first connector and an equipment mounting panel is realized through a sealing rubber pad, and waterproof sealing between the first connector and the second connector is realized through a flexible sealing element; a flange plate is arranged on a connector shell I of the first connector, and waterproof sealing is realized between the flange plate and the equipment mounting panel through the sealing rubber pad; the first connector and the second connector are provided with locking structures which are matched with each other, and the first connector and the second connector are locked with each other after being inserted through the locking structures; and the first connector is also provided with an identification key which is used for playing a role in error-proofing identification. The connector shell has universality, and a terminal structure for transmitting radio frequency signals or differential signals can be installed in the connector shell, so that function of transmitting the radio frequency signals or the differential signals is achieved, the cost is low, the size is small, and the waterproof performance is good.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a sealed electrical connector for vehicles to transmit high-speed radio frequency or differential signals. Background technique [0002] The electronic equipment in the car needs to transmit high-speed radio frequency or differential signals, and also needs to meet the requirements of normal operation in various harsh environments of the car. Typical interconnection occasions, such as the first connector installed on the printed circuit board inside the device, and the second connector to the external cable; another example is the first connector and the second connector connected between two cables . Take the interconnection between printed boards and external cables as an example. Common connectors in the industry, such as the ISO international standard fakra connector, generally do not have a waterproof structure and a fixed structure that cooperates with the equipment cas...

AI Technical Summary

Problems solved by technology

This structure requires the printed board end connector (i.e., the device end) to have a larger outline and occupy more space on the panel of the device, which seriously restricts the miniaturization of the device.

[0004] Moreover, the current connectors for transmitting radio frequency signals and connectors for transmitting differential signals need to design their own shell modules, which are not universal, resulting in increased cost and inconvenient use
