Description
Technical Field

Background
At present, the electrical connector supports a power supply function in addition to data transmission, for example, a Type-C male connector is taken as an example, and a CC terminal thereof is used as a power supply detection terminal; because the sizes and positions of the multiple terminals of the electric connector have standard specifications, in order to consider the power supply safety, the front ends of the CC terminals are shorter than the front ends of the power supply terminals (VBUS and GND), so that the corresponding CC terminals of the male and female end connectors can be contacted after the power supply terminals of the male and female end connectors are contacted; if the male connector is the power supply side, the power is output to the power terminals (VBUS and GND) after the contact with the CC terminal of the female connector is detected through the CC terminal. On the contrary, if the male end connector is pulled out from the female end connector, the corresponding CC terminals of the male end connector and the female end connector are disconnected with the power supply terminals first, so that the output of the power supply to the power supply terminals is stopped first after the disconnection contact is detected by the CC terminals, namely, the power supply is interrupted first before the disconnection contact of the power supply terminals of the male end connector and the female end connector, so as to ensure the power supply safety.
However, because the distance between the front end of the CC terminal and the front end of the power terminal is not long enough, in the pull-out stroke of the male-end connector, the time for the corresponding CC terminal of the male-end connector and the female-end connector to be successively disconnected and contacted is too short, and the power output is not interrupted before the power terminal of the male-end connector and the female-end connector is disconnected and contacted, so that sparks (electric arcs) are generated at the moment that the power terminals of the male-end connector and the female-end connector are disconnected and contacted, and the sparks are oxidized to increase the impedance or melt the colloid to damage the electrical connector; therefore, there is a need for an improved electrical connector that avoids sparking when the male connector is removed.
