Description

Technical Field

[0001] The utility model relates to the technical field of sliding contact electrical appliance connection, in particular to a power supply connector for a sliding contact electrical appliance. Background Art

[0002] Safety busbars are widely used in the metallurgical industry. They are composed of busbar guide rails and insulating sheaths. The busbar guide rails are generally made of copper or aluminum alloy and are connected by single lengths of 4 to 6 meters. They are connected to a power source to draw power for the moving busbar collector. The busbar collector runs along the busbar guide rails to supply power to the moving vehicle. However, most of the existing busbar collectors are prone to jumping when they run to the contact position of the two busbars, which leads to sparking. After the carbon brushes are excessively worn, the height of the carbon brushes in the busbar is reduced, and the busbar collector is prone to fall out of the busbar, thereby affecting the normal operation of the vehicle. Therefore, the carbon brushes need to be removed and replaced. Most of the existing carbon brushes are integrally formed at the connection parts. For example, the existing known model: SN64993619 seamless busbar collector, which makes it impossible to remove the carbon brushes on the busbar collector. Therefore, the entire collector needs to be replaced after the carbon brushes are worn, which seriously increases the maintenance cost.

[0003] After searching, a sliding wire collector disclosed in the prior art (application number: CN202320080888.9) records that "a connecting frame is provided on the side of the sleeve, a mounting plate is provided on the side of the connecting frame away from the sleeve, a mounting seat is provided on the mounting plate, a carbon brush is provided on the mounting seat, a mounting groove is provided on the mounting seat, the mounting groove coincides with the lower side of the carbon brush, a connector is fixedly connected to the lower surface of the mounting seat, the upper side of the connector extends into the mounting groove, a docking groove is provided on the upper surface of the connector, a wire body is provided on the lower side of the connector, and the lower surface of the carbon brush is fixedly connected to the lower surface of the mounting seat. The fixed connection is provided with a docking column, and the mounting seat is provided with a fixing mechanism. "; The carbon brush of the sliding wire collector is detachably connected to the mounting seat, so when the carbon brush is worn, a new carbon brush can be replaced, thereby avoiding as much as possible the problem of the sliding wire collector falling out of the sliding wire due to the reduction of the height of the sliding piece in the sliding wire, thereby ensuring the safety of the equipment during operation. However, the sliding wire collector only solves the problem of loading and unloading the carbon brush, but does not solve the problem that after the carbon brush is excessively worn, the height of the carbon brush in the sliding wire is reduced, and the sliding wire collector is prone to falling out of the sliding wire, and cannot effectively ensure the safety of the sliding contact electric appliance during movement.
