Detailed Description

For the purpose of clearly illustrating the embodiments, structures and effects achieved by the present invention, the following description is made with reference to the drawings:

referring to fig. 1, a structure of a positioning member 10 is shown, in which the positioning member 10 has a side wall spirally surrounding along a virtual axis, and the side wall has an inner side wall surface 11 facing the virtual axis and an outer side wall surface 12 far away from the virtual axis. The outer wall 12 defines a generally cylindrical ring-positioning region that is in partial contact with the inner circumferential surface of a ring 20 (shown in FIG. 2). In other words, the sidewall has a helical outer edge, so that the contact surface between the outer wall 12 and each conductive ring 20 does not form a closed contour. In addition, the positioning member 10 is made of an insulator, and the outer wall 12 further has a plurality of conductive ring positioning slots 13, so that the conductive rings 20 are disposed at intervals without electrical connection, thereby replacing the insulating ring in the prior art.

Referring to fig. 2 to fig. 3, an assembly diagram of a slip ring rotor module is shown, in which the positioning element 10 has the above structure, the conductive ring 20 can be partially contacted and disposed in the positioning groove 13 of the outer side wall 12, and under the condition that the conductive wire 30 and the conductive ring 20 are linked, the connection portion of the conductive wire 30 and the conductive ring 20 can be positioned at the spiral outer edge of the side wall, so that the conductive wire 30 is disposed on the inner side wall surface 11 and extends axially to be guided out of the positioning element 10. Therefore, the conducting rings 20 are sleeved and stacked along the virtual axial direction to generate the appearance of the collector ring rotor, the conducting wires 30 can be uniformly distributed on the inner side wall surface 11 along the axial direction to form a uniform circular shape, and then the structure is packaged to form a modular structure of the collector ring rotor.

Since the positioning member 10 has a structure for positioning the conductive ring 20 and the conductive wire 30 at the same time, the number of other positioning members (e.g., insulating rings and conductive wire positioning members) can be reduced, and the positioning structure can be directly used for injection molding of the slip ring rotor module.

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

The utility model discloses still provide a manufacturing approach of collecting ring rotor module adopts the setting element 10 shown in figure 1, makes collecting ring rotor module 1 shown in figure 4, contains following step:

in step S10, a positioning member 10 is provided, which has a side wall spirally surrounding 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 wall 12 defines a substantially cylindrical ring-positioning portion and has a plurality of ring-positioning slots 13, however, the contact surface between the outer wall 12 and each ring 20 does not form a closed contour.

In step S20, the conductive rings 20 are sequentially sleeved on the outer side of the sidewall, so that the conductive rings 20 are positioned in the positioning slots 13. In this step, the conductive wires 30 electrically connecting the conductive rings 20 are extended into the inner sidewall surface 11 against the outer edge of the sidewall and are sequentially arranged along the inner side of the sidewall to form a uniform circle. However, the step of installing the conductive wire 30 can also be changed according to the specific structure (such as the positioning groove on the outer edge of the sidewall, the longitudinal positioning groove on the inner sidewall 11, or the positioning hole) of the positioning member 10, so that the conductive wire 30 and the conductive ring 20 are electrically connected.

Step S30, the conductive ring 20, the conductive wires 30 and the positioning element 10 are encapsulated by injection molding, the outer wall 12 of the positioning element 10 is formed into a uniform cylindrical shape, the outer ring surface of the conductive ring 20 protrudes and exposes relative to the outer wall 12 of the positioning element 10 to contact the brushes 40 and 41 to form a conductive state, other parts of the conductive ring 20 and the conductive wires 30 are fixedly encapsulated to form the slip ring rotor module 1, and in addition, the plurality of conductive wires 30 annularly surrounded are also encapsulated and positioned together to form a uniform circular shape, and only one end to be electrically connected is exposed.

therefore, the utility model discloses a collecting ring rotor module 1 can reduce the step that sets up of insulating ring, wire setting element, forms the rotor module of shape homogeneous, and the easy management and control of shaping size.
