secondly, the conductive element exposes, easily touches the conductive element when the people touches the mainboard, and has heavy current, high voltage application on the board, the risk of someone for electrocution.

In order to solve the above problems, the prior art generally provides a housing outside the connector, for example, a corrugated protective cover of an electrical connector disclosed in patent CN110542012A discloses the following technical contents: comprises a core-level cover body, a corrugated cover body and a boosting cover body; one end of the core-level cover body is connected with the core-level installation through a turned edge, the other end of the core-level cover body is of a slot structure, one end of the corrugated cover body is connected with a slot of the core-level cover body in a matched mode, the other end of the corrugated cover body is in threaded connection with the boosting cover body, one end of the boosting cover body is connected with the booster through the turned edge in an installation mode, and the other end of the boosting cover body is in threaded connection with the corrugated cover body; the axes of the core-level cover body, the corrugated cover body and the boosting cover body are overlapped. But it solves the problems of overlong cable network length between the traditional core level and the boosting, large signal attenuation degree, loss to carrying capacity, influence on normal work of an electrical system and the like.

Patent 201580050086.1 discloses a protective cover for a plug connector housing, which specifically includes: the plug connector housing is provided for receiving a plug connector module, wherein the protective hood is designed with a plug side and the plug side is provided for closing the plug connector housing in an environmentally sealed manner, wherein the plug side of the protective hood is designed with two spring arms for holding on the plug connector housing, the plug side of the protective hood has at least one receptacle, and the receptacle is designed for mechanically contacting the plug connector module. But it solves mainly the plugging problem, which through the mechanical connection between the protective cover and the plug connector module fixes the plug connector module against damage in transport and against loosening and falling off when unfastening the protective cover. The plug connector module can furthermore be removed from the plug connector housing together with the protective hood.

Therefore, there is a need for a protective cover that can protect the connector from contamination by dust and other foreign matter.
