Electrical connector

The present invention provides an electric connector which reliably prevent invasion of unnecessary objects such as water and dust through a simple structure. The electrical connector is provided with a sealing housing (6) which is composed of tubular members, and an electrically insulative connector housing. According to the sealing housing, the metal boards with preset sizes and thicknesses are tubularly bent to a member which is internally provided with a hollow hole with a preset size, and furthermore two ends of each metal board are jointed. Furthermore at least one end is provided with an opening. The connector housing is provided with a contact with high conductivity. The connector housing is inserted into hollow hole of the sealing housing for performing electromagnetic shielding. A housing waterproof unit which prevents invasion of the water inwards from outer side is provided between the connector housing (3) and a contactor (2). A contactor waterproof unit which prevents similar invasion is provide
