Problems solved by technology

[0002] A connector is a conductor device that bridges two conductors on a circuit so that current or signals can flow from one conductor to another conductor. With the advancement and development of science and technology, a connector can connect multiple circuits at the same time. Multiple conductors perform current output or signal transmission at the same time, and the output voltage of each connector port is rated. In order to ensure the same voltage, most connectors are connected in parallel circuits, but the existing connectors are relatively wet In the process of power output in an environment, if the connection port of a single connector is damp and short-circuited, the resistance of the line will instantly become 0. Due to the nature of the current, all the current will move along the short-circuit line. As a result, the current of this line is very large, causing other lines to lose current, causing other connectors to have no current output, and at the same time causing great damage to the power supply, and it is difficult to judge the damaged interface, which needs to be measured by a special electric measuring instrument

Abstract

The invention discloses a connector for preventing short circuit between a terminal and a metal shell, which structurally comprises a connecting head, a power connection plate, an isolation plate, a fixing groove and an input groove, wherein the top surface of the connecting head and the fixing groove are integrally molded. When the connector is used in a humid environment, the short circuit between the terminal and the metal shell is avoided through the isolation plate. Meanwhile, if a short circuit is generated in a single joint structure, an electromagnet plate can be driven by concentrated current to eject out of an output head, a circuit is connected again through two connecting handles, and a conductive block is in contact with a resistance frame through bending of a folding guide plate in an extending plate in the process of connecting handle impact, so that impact can be effectively absorbed, the risk of short circuit continuously caused by too low resistance is avoided at the same time, other lines still output current after a single joint structure is short-circuited, and great damage to a power supply is avoided.Meanwhile, the damaged structure is more prominent, thereby being convenient to observe and more beneficial to replacement and maintenance.
