Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of conductive ring manufacturing, in particular to a welded conductive ring. BACKGROUND
[0002] The conductive ring is used to release the induced voltage generated by the current output from the frequency converter when the output shaft of the variable frequency motor is higher than the action of the variable frequency switch through the current of the output shaft of the variable frequency motor, and at the same time avoid the voltage to break the oil film between the bearing balls on the output shaft of the variable frequency motor, so as to cause the electric corrosion of the bearing seat, bearing balls and track of the bearing. However, the process difficulty of the current conductive ring manufacturing mainly focuses on the fixation of the conductive fiber, because the conductive fiber needs to be fixed radially on the inner circumferential surface of the conductive ring. In the traditional way, one end of each conductive fiber is fixed on the inner circumferential surface of the conductive ring by welding or bonding, and a clamping device is needed to hold the conductive fiber during the welding or bonding process of the conductive fiber. At the same time, during the process of directly welding the conductive fiber and the conductive ring, the contact surface between the conductive fiber and the conductive ring is very small due to the small size of the conductive fiber, resulting in high process difficulty. CONTENT OF THE UTILITY MODEL
[0003] The application is aimed at the shortcomings of the prior art, and adopts the way of setting the flattened plug at the end of the conductive fiber to cooperate with the plug-in connector arranged on the mounting bracket or directly inserting the conductive fiber into the plug-in connector, so that the welding surface is increased and the welding difficulty is reduced by the setting of the plug-in connector during welding, and the conductive fiber is directly inserted into the plug-in connector, so that the conductive fiber does not need to be held during the welding process, solving the problem of high process difficulty of the traditional conductive ring manufacturing process.
[0004] The technical scheme of the application is as follows:
[0005] A welded conductive ring, comprising a mounting bracket, a plug-in connector and a conductive fiber, wherein the plug-in connector is provided with a plug-in through hole matched with the conductive fiber, the axis of the plug-in through hole is directed to the center of the mounting bracket, and the plug-in connector is welded on the end surface of the mounting bracket; after one end of the conductive fiber is inserted into the plug-in through hole, the other end of the conductive fiber, which is away from the plug-in connector, is directed to the center of the mounting bracket.
[0006] Preferably, a fixing sheet is further arranged on the plug-in connector.
[0007] Preferably, the plug-in connector and the fixing sheet are integrally formed by machining or aluminum extrusion.
[0008] Preferably, the fixing sheet is welded to the mounting bracket by laser welding, ultrasonic welding, tungsten argon arc welding or gas tungsten arc welding.
[0009] Preferably, the end of the insertion hole near the center of the mounting bracket has a chamfer or rounded corner to protect the conductive fibers.
[0010] Preferably, there is at least one insertion hole, and one insertion hole corresponds to one conductive fiber.
[0011] Preferably, a retaining wall is provided on the outer circumference of the mounting bracket, and the top of the retaining wall is flush with the side of the connector facing away from the mounting bracket.
[0012] Preferably, one end of the conductive fiber is provided with a flattened plug. After one end of the conductive fiber is inserted into the flattened plug, the flattened plug is then inserted into the plug hole so that the conductive fiber does not fall out.
[0013] The working principle and beneficial effects of this application are as follows:
[0014] This application designs a weldable conductive ring by using a flattened plug at the end of the conductive fiber to work with a connector mounted on a mounting bracket, or by directly inserting the conductive fiber into the connector. The connector design increases the welding surface during welding, reducing the welding difficulty. This allows the conductive fiber to be fixed to the upper part of the mounting bracket and then detached. Furthermore, it eliminates the need to support the conductive fiber during welding, thus solving the problem of high manufacturing difficulty in traditional conductive rings.

[0016] Fig. 2 This is a schematic diagram of the structure after removing one connector in this application.
[0017] The components include: 1. Mounting bracket; 2. Connector; 3. Conductive fiber; 4. Plug-in through hole; 5. Fixing plate; 6. Chamfer / rounded corner; 7. Retaining wall. Detailed Implementation
[0018] like Figs. 1-2 As shown, a welded conductive ring includes a mounting frame 1, a connector 2, and a conductive fiber 3. The connector 2 has a insertion through hole 4 that mates with the conductive fiber 3. One end of the axis of the insertion through hole 4 faces the center of the mounting frame 1. The connector 2 is welded to the end face of the mounting frame 1. When one end of the conductive fiber 3 is inserted into the insertion through hole 4, the end of the conductive fiber 3 facing away from the connector 2 faces the center of the mounting frame 1.
[0019] In the present application, after the adapter 2 is set, when the conductive ring is made, one end of the wire fiber 3 is inserted into the adapter 2, which makes the adapter 2 placed on the mounting frame 1 stable, so that the conductive fiber does not need to be held during the welding process, and the adapter 2 can be directly welded on the mounting frame 1, which is very convenient. When the current of the output shaft of the variable frequency motor is released, only the end of the conductive fiber 3 outside the adapter 4 needs to be in contact with the output shaft of the variable frequency motor to achieve the release.
[0020] Preferably, the fixing sheet 5 is arranged on the adapter 2. By arranging the fixing sheet 5, the fixing sheet 5 is welded on the mounting frame 1 together with the adapter 2 during welding, and the fixing sheet 5 plays the role of a reinforcing rib, so that the adapter 2 is more stable when welded on the mounting frame 1.
[0021] Preferably, the adapter 2 and the fixing sheet 5 are integrally formed by machining or aluminum extrusion.
[0022] Preferably, the fixing sheet 5 is welded to the mounting frame 1 by laser welding, ultrasonic welding, tungsten argon arc welding or gas tungsten arc welding.
[0023] Preferably, the adapter 4 is formed with a chamfer or a round corner 6 at one end close to the center of the mounting frame 1 for protecting the conductive fiber 3. In this way, the end of the adapter 4 is prevented from scratching the conductive fiber 3, so that the wire fiber 3 is not easily broken.
[0024] Preferably, the adapter 4 is at least one, and one adapter 4 corresponds to one conductive fiber 3.
[0025] Preferably, the mounting frame 1 is provided with a row of retaining walls 7 on the outer circumferential surface, and the top end of the retaining wall 7 is flush with the back of the adapter 2 away from the mounting frame 1. The retaining wall 7 protects the adapter 2 and the conductive fiber 3.
[0026] Preferably, one end of the conductive fiber 3 is provided with a flattened plug 8, and the flattened plug 8 is inserted into the adapter 4 after the conductive fiber 3 is inserted into the flattened plug 8, so that the conductive fiber 3 does not fall off. In this way, the flattened plug 8 is arranged to facilitate the insertion of the conductive fiber 3 into the adapter 4.
