Description

High-current connector assembly, wire end connector and board end connector Technical Field The utility model belongs to the technical field of connectors, and particularly relates to a high-current connector assembly, a wire end connector and a board end connector. Background A connector is a device for interfacing an electronic product with a power source or other electronic products, and generally includes a connection terminal, a wire, and a body encapsulated at a connection portion of the connection terminal and the wire. The line end connector and the board end connector are commonly used in combination and are mated by plugging with each other. The connection stability between two connectors is of great importance, and once loose, the connection can cause power failure and network failure to cause loss and damage of production data. The plugging mode realized only through tight fit is easy to loosen, and particularly the large-current connector is large in size and is also provided with a thicker cable, the cable can be bent when in use, and the connecting part of the connector can be stressed by forces in various directions, so that shaking and loosening are finally generated.
