The through hole 41 is internally provided with a conductive tube 5 in a penetrating manner, and the conductive tube 5 extends into the first mounting hole 123/the second mounting hole 133. The lower end face of the conductive tube 5 is higher than the lower end face of the insulator 2, and when the conductive tube 5 is not connected with a conductive object, the conductive tube 5 is not contacted with the conductive object, so that the conductive tube 5 is prevented from being electrified, and the service life of the conductor 1 is not easy to reduce.
Referring to fig. 4 and 5, the outer circumferential surface of the conductive pipe 5 is fixedly connected with a driving ring 51 and a limiting ring 52, and both the outer diameter of the driving ring 51 and the outer diameter of the limiting ring 52 are larger than the inner diameter of the through hole 41. The drive ring 51 is located on the side of the cymbal-shaped washer 4 remote from the first conductive plate 12/second conductive plate 13. The limiting ring 52 is positioned on one side of the cymbal-shaped gasket 4, which is close to the first conducting plate 12/the second conducting plate 13, a chamfer is formed on the limiting ring 52, and the chamfer is positioned at the junction of one side of the limiting ring 52, which is far away from the driving ring 51, and the outer circumferential surface of the limiting ring 52. When the connecting piece is not connected with the conductive object, the limiting ring 52 and the first conductive plate 12/the second conductive plate 13 leave a gap, so that the conductive tube 5 has a movable space towards the first conductive plate 12/the second conductive plate 13.
A production process of an automobile energy storage structure connecting piece comprises the following steps:
step one, stamping the blank to form a limiting block 31;
step two, stamping and forming a limiting hole 32 and a mounting hole on the limiting block 31, and mounting a cymbal-shaped gasket 4 on the limiting block 31;
step three, placing the conductor 1 in an injection mold to perform injection molding to form an insulator 2;
and step four, mounting the conductive tube 5 on the cymbal-shaped gasket 4.
The implementation principle of the embodiment 2 is as follows: the electric conduction pipe 5 and the cymbal-shaped gasket 4 are arranged, when the electric conductor 1 is connected with an electric conduction object through the bolt, the cymbal-shaped gasket 4 deforms, so that the electric conduction pipe 5 moves towards the electric conduction object until the electric conduction pipe 5 contacts with the electric conduction object, the electric conductor 1 is electrically connected with the electric conduction object, and the compression deformation cymbal-shaped gasket 4 enables the bolt not to rotate easily, so that the electric conduction object has an anti-conveying function.
