Board-to-board connectors usually include a pair of plug and socket connectors, which are respectively installed on two parallel and separate PC female end boards, and are configured to be mechanically and electrically connected to each other, so that the plug and socket connectors on the corresponding PC female end boards can transmit signals by being electrically connected to each other. Wire-to-board connectors usually include a wire-end connector and a board-end connector connected to the wire-end connector, so as to realize the current or signal transmission between the components of the device and the circuit board. Although board-to-board connectors and wire-to-board connectors have played an important role in their respective application fields, whether it is a board-to-board connector or a wire-to-board connector, a single type of connector still has the following defects when facing the complex needs of modern electronic equipment: (1) A single type of connector can only meet specific connection requirements and cannot adapt to the diverse connection requirements of different devices and application scenarios, and its adaptability range is limited.

At the same time, it can also be easily upgraded and expanded. By replacing some components of the board-end connector module or the line-end connector module according to actual needs, the changing connection needs of the equipment can be met.

[0018] (2) The present invention provides a high-current connector with a board end and a wire end combination.

Since a third limiting groove is respectively provided on the two inner side walls of the second accommodating cavity, and a third limiting member corresponding to the third limiting groove is provided on the outer side wall of the second shell body, the third limiting groove and the third limiting member are used in coordination with each other, so that the signal terminal module can be effectively prevented from rotating and shifting relative to the second accommodating cavity when subjected to external force, thereby improving the connection stability between the signal terminal module and the first shell body.

Since a fourth limiting groove is provided at the upper end of the second accommodating cavity, and a fourth limiting member corresponding to the fourth limiting groove is provided at the upper end of the second shell, the fourth limiting groove and the fourth limiting member are used in coordination with each other, so that the signal terminal module can be effectively prevented from being separated from the second accommodating cavity when subjected to external force, thereby further improving the connection stability between the signal terminal module and the first shell.

[0023] (7) The present invention provides a high-current connector that combines a board end and a wire end.
