Description

Collector ring rotor module

The present invention relates to a slip ring rotor module. More precisely, it relates to a slip ring rotor modular structure that can simplify the assembly process.

The cooperation of the slip ring rotor and the brush can be applied to the electromechanical system that requires continuous rotation and also needs to transmit power and/or signals to avoid sprains during the rotation of the wire. Generally speaking, the manufacturing method of the collector ring rotor is formed by stacking the metal ring and the insulating ring in the axial direction to ensure the insulation between the adjacent slip rings, or the assembled insulating metal ring assembly is assembled and positioned. However, this manufacturing method is still complicated, and it is impossible to arrange the wires connected to the stator.

Based on the above-mentioned defects, the present invention provides a slip ring rotor module, which includes a positioning member, a plurality of conductive rings nested along the virtual axis of the positioning member and a stack, and a plurality of wires are respectively electrically connected to the conductive rings. The positioning member has a side wall that is spiral along the virtual axis.

In this way, the conductive ring can be located outside the side wall of the positioning member, and the wire can be located inside the side wall of the positioning member, and the connection position of the conductive ring and the wire can be positioned at the outer edge of the spiral side wall, reducing other positioning members (such as insulating ring, wire positioning member ), and by encapsulating this structure to form a modular ring rotor structure.

To further explain, the material of the positioning member may be an electrical insulator as a whole, instead of the function of the conventional insulating ring, the lateral cross-section of the positioning member side wall is a discontinuous surface, so that the conductive ring only partially contacts the positioning member, and the positioning member may also be provided with perforations Let the wire pass through and be located inside the side wall of the positioning member. In addition, a plurality of positioning grooves for the installation of the conductive ring or the wire may be provided on the outside or inside of the side wall of the positioning member.

In order to clearly explain the specific implementation mode, structure and achieved effects of the new model, the illustrations are as follows:

Referring to FIG. 1, a structure of a positioning member 10 is shown. The positioning member 10 has a side wall spiraling along a virtual axis. The side wall has an inner side wall surface 11 facing the virtual axis and an outer side wall surface 12 away from the virtual axis. The outer wall surface 12 defines a positioning area of the conductive ring which is slightly cylindrical, and is in contact with the inner ring surface of the conductive ring 20 (as shown in FIG. 2 ). In other words, the side wall has a spiral outer edge, so that the contact surface between the outer side wall surface 12 and each conductive ring 20 does not form a closed contour. In addition, the material of the positioning member 10 is an insulator as a whole, and the outer side wall surface 12 also has a plurality of conductive ring positioning grooves 13, so that the plurality of conductive rings 20 are spaced apart without electrical connection, replacing the role of the conventional insulating ring.

Please refer to FIG. 2 to FIG. 3, which shows an assembly schematic diagram of the collector ring rotor module. Since the positioning member 10 has the above-mentioned structure, the conductive ring 20 can be partially contacted to be provided in the positioning groove 13 of the outer wall surface 12. In the state where 30 and the conductive ring 20 are connected, the connection portion of the conductive wire 30 and the conductive ring 20 can be positioned on the spiral outer edge of the side wall, so that the conductive wire 30 is disposed on the inner side wall surface 11 and guides the positioning member 10 from the axial extension. Thereby, a plurality of conductive rings 20 are nested and stacked along the virtual axis, resulting in the appearance of the collector ring rotor. The plurality of wires 30 can be distributed axially or evenly on the inner wall surface 11 to form a uniform circle, and then by Encapsulate this structure to form a modular ring rotor structure.

Since the positioning member 10 has a structure for positioning the conductive ring 20 and the conductive wire 30 at the same time, the arrangement of other positioning members (such as an insulating ring and a conductive wire positioning member) can be reduced, and the positioning structure can be directly molded into the current collector ring rotor module.

In other embodiments, as long as the wires 30 can be placed and arranged in the space defined by the inner sidewall surface 11, the number of sidewalls of the positioning member 10 can be plural, forming a multi-strand spiral structure. In addition, the positioning groove 13 of the side wall may also be provided with a through hole. In other words, the cross section of the side wall is a discontinuous surface, so that one end of the wire 30 is electrically connected to the conductive ring 20 through the through hole, and the other end of the wire 30 extends to the inner wall surface 11 to be aligned.

The manufacturing method of the slip ring rotor module uses the positioning member 10 shown in FIG. 1 to manufacture the slip ring rotor module 1 shown in FIG. 4, which includes the following steps:

In step S10, a positioning member 10 is provided. The side wall has a spiral shape along the virtual axis, and the side wall has an inner side wall surface 11 facing the virtual axis and an outer side wall surface 12 away from the virtual axis. The outer side wall surface 12 defines a slightly cylindrical conductive ring positioning area, and also has a plurality of conductive ring positioning grooves 13, however, the contact surface between the outer side wall surface 12 and each conductive ring 20 does not form a closed contour.

In step S20, a plurality of conductive rings 20 are sequentially placed on the outside of the side wall, so that the conductive ring 20 is positioned in the plurality of positioning grooves 13. In this step, the wire 30 electrically connected to each conductive ring 20 is extended into the inner wall surface 11 against the outer edge of the side wall, and arranged in sequence along the inner side of the side wall to form a uniform circle. However, the step of installing the wire 30 can also be changed according to the specific structure of the positioning member 10 (such as the positioning groove on the outer edge of the side wall, the longitudinal positioning groove on the inner wall surface 11 or the positioning hole), so that the wire 30 and the conductive ring 20 appear The state of the electrical connection.

In step S30, the conductive ring 20, the wire 30 and the positioning member 10 are packaged by injection molding to form the outer wall surface 12 of the positioning member 10 into a uniform cylindrical shape, and the outer ring surface of the conductive ring 20 protrudes and is exposed relative to the outer wall surface 12 of the positioning member 10 In order to form a conductive state by contacting the brushes 40 and 41, the other parts of the conductive ring 20 and the wires 30 are fixedly packaged to form the collector ring rotor module 1, in addition, the plural wires 30 surrounded by the ring are also packaged and positioned together to form A uniform circle with only one end exposed to electrical connection.

In this way, the current-collecting ring rotor module 1 of the present invention can reduce the installation steps of the insulating ring and the wire positioning member, form a rotor module with a uniform shape, and the forming size is easy to control.
