Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

The embodiment of the present application provides a current collector to solve the problem that the cables in the existing current collector easily constrain the movement of the carbon brush. It will be described below in conjunction with the accompanying drawings.

In the embodiment of the present application, as shown in FIGS. 1 and 2 , the current collector 10 includes a slider 20 , a conductive shaft 30 and a conductive component 40 . The slider 20 has a conductor 21, the conductive shaft 30 is connected to the slider 20, and is in electrical contact with the conductor 21, the conductive component 40 includes a wire 45, and the wire 45 has a first A connection end 451 and a second connection end 452, the first connection end 451 is electrically connected to the conductive shaft 30, and the second connection end 452 is used for electrical connection with the electrical equipment to be used.

Specifically, as shown in FIG. 1, the current collector 10 in the embodiment of the present application is mainly used in a trolley line system 100. The trolley line system 100 generally includes an energized guide rail 110, which is connected to a power source, and the current collector 10 passes through The sliding contact 20 slides in the energized guide rail 110 to take power, and the sliding contact 20 is connected to the standby power equipment through a cable, thereby realizing the mobile power supply of the standby power equipment.

Wherein, as shown in Figure 2 and Figure 3, the slider 20 in the collector 10 has a conductor 21, the conductor 21 can be a conductive copper sheet, a conductive block, a conductive roller and other structural forms, and the conductor 21 passes through the conductive guide rail 110 sliding contact to realize mobile power taking. The part of the conductive body 21 exposed from the conductive rail 110 is covered with an insulator 22 to prevent electric shock or short circuit with external conductive structures.

Please refer to Fig. 2, Fig. 3 and Fig. 6, the conductive rotating shaft 30 in the collector 10 is connected with the slider 20, generally speaking, it is connected in rotation, so that the slider 20 has a protrusion when sliding into the energized rail 110, When the position is on a slope or a curved section, it can adaptively swing to keep sliding smoothly. Different from traditional collectors, the conductive shaft 30 in the embodiment of the present application can conduct electricity and is in electrical contact with the conductor 21 on the slider 20 , that is, the connection point between the conductive shaft 30 and the slider 20 It is not only a rotating connection point, but also an electrical energy export point, which not only simplifies the structure of the current collector 10, but also makes the cables used to connect the electrical equipment to be used not directly connected to the sliding contact 20, and the sliding contact 20 can also be connected The electric energy on the 20 is transmitted to the electrical equipment to be used.

Wherein, the conductive rotating shaft 30 can be made of conductive material as a whole, or only a part of it can be formed of conductive material, for example, the shaft center is made of conductive material, and the shaft sleeve outside the shaft center is made of insulating material, only the conductive part in the shaft structure needs to be ensured It only needs to be in electrical contact with the conductor 21 of the slider 20, and the specific structural form can be designed according to the actual situation. The conductive material is not limited, as long as it can conduct electricity, for example, the same conductive material as the conductor 21 can be used, which is not only convenient to use the same material for processing, but also conducive to stable conduction, and can reduce wear when rubbing against each other.

In addition, there can be many ways of electrical contact between the conductive shaft 30 and the conductor 21, for example, the conductive part on the conductive shaft 30 is rotationally connected to the conductor 21 through a conductive pin, so that it will not affect the The rotation of the conductor 21 can lead out the electric energy on the conductor 21 again. Alternatively, a shaft structure and a hole structure that can be rotatably connected are formed directly on the conductive shaft 30 and the conductor 21 , so that the conductive shaft 30 and the conductor 21 are directly rotatably connected. Alternatively, a cavity is provided on the conductor 21, and the conductive shaft 30 partially extends into the cavity of the conductor 21, and keeps in contact with the conductor 21 without interfering with the rotation of the conductor 21. At this time, the conductive shaft 30 and the sliding contact The rotational connection between the parts 20 can be completed by the insulating parts of the two parts.

As shown in Figure 2, after the electrical energy on the conductor 21 is transmitted to the conductive shaft 30, in order to further derive the electrical energy on the conductive shaft 30, the embodiment of the present application also includes a conductive component 40, the conductive component includes a wire 45, such as As shown in FIG. 1 , the wire 45 has a first connection end 451 and a second connection end 452, the first connection end 451 is electrically connected to the conductive rotating shaft 30, and the second connection end 452 is used for electrically connecting the electrical equipment to be used. Connect, and then transmit the electric energy to the standby electric equipment, realize the mobile power supply of the standby electric equipment.

Wherein, there can be many ways to realize the electrical connection between the first connection end 451 of the wire 45 and the conductive shaft 30, for example, the wire 45 can be directly connected to the conductive shaft 30, or, based on the design principle of not affecting the rotation of the conductive shaft 30 , the conductive assembly 40 can also include a bearing structure or a similar transition structure, the bearing structure is sleeved outside the conductive shaft 30 (or connected to the end of the conductive shaft 30) and electrically contacted, and the wire 45 does not rotate with the bearing structure part of the electrical connection. Alternatively, the conductive assembly 40 may also include a conductive block, a conductive pin, etc., which are fixed on one side of the conductive shaft 30 and are in rotational contact with the outer peripheral surface of the conductive shaft 30 and are in electrical contact. blocks, conductive pins and other electrical connections. For the part that needs to be fixedly installed in the conductive assembly 40, in the current collector 10, the conductive rotating shaft 30 is generally also covered with a shaft sleeve (that is, the rotating connector 51), so the part that needs to be fixedly installed in the conductive assembly 40 can be installed on the shaft. put on.

In summary, it can be understood that the current collector 10 provided by the present application is in electrical contact with the conductor 21 on the slider 20 through the conductive shaft 30 , and at the same time is in electrical contact with the conductive shaft 30 through the conductive component 40 , and the conductive component is then passed through the wire 45 It is electrically connected with the electrical equipment to be used, that is, the wire 45 transmits the electric energy on the sliding contact 20 to the electrical equipment to be used by electrically connecting with the conductive rotating shaft 30 , so that it does not need to be directly connected to the sliding contact 20 . In this way, the situation that the movement of the sliding contact 20 is constrained when the cable is directly connected to the sliding contact 20 can be avoided, effectively solving the problem that the cable in the current collector 10 is easy to affect the carbon brush (that is, the sliding contact 20 ).
