The connector includes a Barklip connector module, a cable module, and a power connector; the Barklip connector module is electrically connected to a plurality of corresponding power connectors through a cable; a plurality of power connector interfaces are provided through the barklip connector to meet the power supply requirements of customers for multiple chassis units; however, when docking the wires, the wires need to be attached to the connector through the elasticity of the terminals themselves. But during installation, it is necessary to open the connector one by one and then put in the wires, which is not convenient and has low efficiency.

[0004] Therefore, it is necessary to develop a portable high-power connector to solve the above problems. Summary of the Utility Model

[0008] Terminals, arranged inside the outer plastic part, and their surfaces are exposed inside the frame hole.

[0009] A spring piece, located inside the outer plastic part. The spring piece can extend into the frame hole and contact the exposed surface of the terminal.

[0010] A movable handle, used to pull the spring piece to cause the spring piece to deform and disengage from or contact the surface of the terminal.

[0011] Further, the bottom of the terminal penetrates through the outer plastic part and is connected to other components, and its top is bent to abut against the spring piece.

[0012] Further, the top of the terminal has a protrusion, and the protrusion is formed by protruding outward from the lower surface of the bent top of the terminal for docking with the spring piece.

The end of the spring sheet abutting against the top of the terminal has a through hole running through its upper and lower surfaces, and the through hole is used to accommodate the protrusion.

[0014] Furthermore, the top of the terminal extends from the side to form a limiting portion, and the limiting portion bends toward the spring sheet to limit the position of the spring sheet.

[0015] Furthermore, the terminal further includes a temperature sensing portion, and the temperature sensing portion extends outward from the terminal surface, penetrates the outer plastic part, and extends to the outside of the outer plastic part.

[0016] Furthermore, the temperature sensing portion has a groove formed by being recessed inward from its surface, and the groove is used to expand the temperature sensing area.

[0017] Furthermore, the spring sheet further includes a connecting arm, which is formed by extending outward from a side where the spring sheet contacts the plane of the terminal and abuts against the movable handle.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is a portable high-power connector, which is convenient and efficient. The toggle switch is pulled by external force to drive the connecting arm to move upward, and the connecting arm drives the spring to break away from the contact with the terminal. The wire passes through the frame hole into the outer plastic part, and the toggle switch is released. The spring rebounds by its own elastic force, and its end presses the wire, so that the wire fits tightly with the surface of the terminal, thereby improving the docking efficiency.
