[0047] As an implementation form, the conductive part 20 is a conductive sheet, and the isolation strip 24 and the brush guide groove 25 are integrally formed. The installation is convenient, and the contact failure of the slide wire 2 is reduced.
[0048] As an implementation form, the current collector body 1 is mounted on a mobile device.
[0049] As an implementation form, the mobile device is a shuttle shell replacing device 4 of an embroidery device.

The rack 50 is arranged on the front side of the slide wire 2. The shuttle shell replacing device 4 is slidably mounted on the corresponding slide rail 5 through a sliding block. A driving motor is arranged in the shuttle shell replacing device 4. A gear is connected with the output end of the driving motor. The shuttle shell replacing device 4 is connected to the rack 50 matched therewith through the gear. The constant force spring 3 is adopted to keep the brush 10 and the conductive part 20 of the slide wire 2 in stable brush pressure. The brush 10 is always in contact with the slide wire 2 during the sliding process. The excessive wear of the brush 10 caused by excessive brush pressure is avoided. The service life of the current collector is increased. The maintenance and repair frequency of the shuttle shell replacing device 4 and the current collector is reduced. The stable operation of the current collector and the shuttle shell replacing device 4 is ensured. The equipment maintenance cost is reduced, and the production efficiency is improved.
