A clamping slot is provided on one side of the internal groove of the joint base 1. The shape of the clamping slot is a cylindrical cavity, and the inside of the clamping slot is adapted to the outer end of the clamping column 14. When the joint is docked and the movable cover 3 is moved down, the clamping column 14 on one side of the movable cover 3 will first shrink to the inside of the movable cover 3. When it moves to one side of the clamping slot of the joint base 1, it can be pushed into the inside of the clamping slot under the action of the spring 12, thereby improving the stability of the movable cover 3 after it is closed. The outside of the movable cover 3 is adapted to the groove inside the joint base 1, and the contact surface between the movable cover 3 and the joint base 1 is provided with a rubber pad to improve the sealing of the contact surface between the movable cover 3 and the joint base 1.

[0028] In addition, the back side of the joint base 1 is fixedly connected to a back plate 4, the interior of the back plate 4 is fixedly connected to a partition plate 5, the interior of the partition plate 5 is fixedly connected to a welding foot 8 and a threaded block 9, and the internal thread of the threaded block 9 is connected to a fixing bolt 6, the outside of the fixing bolt 6 is also sleeved with a gasket 7, the welding foot 8 is sleeved on the outside of the fixing bolt 6, the gasket 7 is located directly above the welding foot 8, and a skylight is opened on the top of the back plate 4, and a movable plate 15 is rotatably connected inside the skylight, which can be entangled with the arc wire during use.

[0029] The above scheme needs to be supplemented with the following: the wiring base is cast in one piece by extruding an aluminum cold plate, which can greatly improve the overall strength of the wiring head. The cold plate extrusion process is a prior art and therefore does not need to be elaborated on.

[0030] The working principle of the utility model is as follows: when installing the connector base 1, one end of the arc wire is wrapped around the outside of the fixing bolt 6, the movable plate 15 on the top is opened, and the fixing bolt 6 is rotated and rotated downward, so that the gasket 7 contacts the welding foot 8 and the arc wire. As the fixing bolt 6 moves downward, the contact between the three becomes tighter, thereby completing the docking with the arc wire. When it is necessary to plug in the wire, the wire can be docked with the plug connector 2, and then the movable cover 3 is moved down. The card column 14 on one side of the movable cover 3 will first shrink to the inside of the movable cover 3, and when it moves to one side of the card slot of the connector base 1, it can be pushed into the card slot under the action of the spring 12, thereby improving the stability of the connection and protecting the connection. It can improve the stability of the movable cover 3 after it is closed, and improve the stability of the connection between the wire and the connector terminal, which is worthy of promotion and use.
