Description

Electrical connector

The present invention relates to the construction of an electrical connector, and more particularly to an electrical connector having a dustproof and waterproof function.

Many known electrical, electronic or electromechanical products are provided with power outlets that are electrically coupled to each other using a power outlet and another mating power plug to form a power transmission line for transmitting power. Since the power outlet is only plugged into and out of the power plug only when it is required to transmit power, for many electrical equipment (such as mobile power or batteries), electronic devices or electromechanical products (such as electric motor vehicles) that are often exposed to the open air or the outside environment. In other words, the power outlet exposed to the open air or the outside environment is easily damaged by rain, dust or other foreign matter.

Taking an electric motor car as an example, the electric motor car has to rely on an external power source to charge the battery in order to be used again than the self-charging hybrid electric vehicle. Therefore, the electric motor vehicle must be provided with a charging socket (which is a kind of power connector), the charging socket and the charging circuit of the electric motor car are electrically connected, and the external power source is plugged and coupled to each other through the other charging plug and the charging socket, and the external power source is electrically connected. It is connected to the charging circuit of the electric motor vehicle, and then the battery of the electric motor vehicle is charged by the external power source. In order to facilitate charging, the charging socket of the electric motor vehicle is generally installed outside the body of the electric motor vehicle, so that the charging plug electrically connected to the external power source can be conveniently coupled with the electric socket of the electric motor vehicle.

When the electric motor car is driving or parked, the charging socket installed on the outside of the vehicle body is often exposed to the environment filled with rainwater and other foreign matter. In order to prevent the charging socket from being invaded by rainwater and foreign matter, the short circuit or the contact is poor. The problem is that a cover body is usually disposed outside the charging socket, and the cover body is generally a hollow member having an opening at one end for covering the outside of the charging socket, and this is required every time charging is performed. The sleeve-type cover is pulled out of the charging socket, so it is slightly inconvenient to use. If it is not properly placed, it is more likely to be lost. Therefore, how to prevent the charging socket from being affected by rain or foreign matter will not cause inconvenience in use. It is one of the problems that the industry pays attention to and constantly seeks solutions.
