Abstract
Description
Technical Field
[0001] The present application relates to the technical field of inductor coils, and in particular to a contact ring assembly for inductors. Background Art
[0002] An inductor is a device that works on the principle of electromagnetic induction. When current passes through a wire, a certain electromagnetic field is generated around the wire, and the wire itself in this electromagnetic field will have an inductive effect on the wires within the range of this electromagnetic field. The effect on the wire itself that generates the electromagnetic field is called self-inductance, that is, the changing current generated by the wire itself produces a changing magnetic field, and this magnetic field further affects the current in the wire. The effect on other wires within the range of this electromagnetic field is called mutual inductance. In actual use, the wires are mostly wrapped around the coil frame to ensure the normal use of the coil.
[0003] Some existing inductor coils are connected to the outside by a welding structure wound with aluminum enameled wire. However, the inductor coils are prone to loosening and damage during movement, resulting in poor contact, which often leads to sparking and burning. Therefore, further improvement is needed. Utility Model Content
[0004] In order to reduce the possibility of poor contact during use, the present application provides a contact ring assembly for an inductor.
[0005] The present application provides a contact ring assembly for an inductor, which adopts the following technical solution:
[0006] A contact ring assembly for an inductor comprises a contact ring body abutting against an inductor coil and a plurality of elastic conductive springs wound around the contact ring body, wherein the inductor coil is arranged in a spiral shape, a conductive shaft is arranged above the inductor coil, the contact ring body is coaxially sleeved on the conductive shaft, and the elastic conductive springs abut against the outer surface of the conductive shaft.
[0007] By adopting the above technical solution, since the contact ring body abuts against the inductor coil, the elastic conductive spring sheet can closely abut against the outer wall of the conductive shaft through its own elasticity to improve the close contact with the conductive shaft to form a conductive loop. Compared with the welding process, the possibility of poor contact of the inductor coil during use is reduced.
[0008] Preferably, an annular slot for inserting the inductor coil is formed on the outer peripheral wall of the contact ring body, and the cross section of the annular slot along the axial direction thereof is V-shaped.
[0009] By adopting the above technical solution, since the inductor coil is arranged in a threaded shape and has a certain curvature, an annular slot for inserting the inductor coil is opened on the outer peripheral wall of the contact ring body, and the cross-section of the annular slot along its axial direction is V-shaped, the direct contact area with the inductor coil can be increased, so as to reduce the possibility of poor contact between the contact ring assembly and the inductor coil.
[0010] Preferably, the contact ring body is slidably sleeved on the conductive shaft, and the conductive shaft rotates around the center of the inductor coil.
[0011] By adopting the above technical solution, the annular slot cooperates with the spiral trend of the inductor coil so that it can slide along the length direction of the conductive shaft as the conductive shaft rotates, so as to change the position of the contact ring assembly on the inductor coil, that is, the number of turns of the inductor coil at this time, so as to change the inductance of the inductor coil at this time.
[0012] Preferably, the elastic conductive spring is detachably connected to the contact ring body.
[0013] By adopting the above technical solution, the elasticity of the elastic conductive spring may be reduced during use, thereby affecting the conductive effect between the conductive shaft and the inductor coil. Therefore, the elastic conductive spring is detachably connected to the contact link to facilitate replacement.
[0014] Preferably, a mounting ring is protruding from one end surface of the contact ring body, the mounting ring is coaxially sleeved on the conductive shaft, the elastic conductive spring abuts against the outer wall of the mounting ring, the elastic conductive spring is penetrated by a screw, and the screw is threadedly connected to the mounting ring.
[0015] By adopting the above technical solution, the elastic conductive spring is installed on the mounting ring by passing a screw through the elastic conductive spring to be threadedly connected with the mounting ring. The threaded connection has a high connection strength and is also easy to disassemble and replace.
[0016] Preferably, the diameter of the mounting ring is smaller than the diameter of the contact ring body, and smaller than the diameter of the annular slot.
[0017] By adopting the above technical solution, the diameter of the mounting ring is smaller than the diameter of the contact ring body and smaller than the diameter of the annular slot, so as to reduce the possibility that the mounting ring touches the inductor coil and damages the inductor coil during practical use.
[0018] Preferably, it further comprises a silver contact point arranged on the elastic conductive spring sheet, wherein the silver contact point abuts against the outer surface of the conductive shaft.
[0019] By adopting the above technical solution, silver contacts are provided. Since silver has good conductivity but is relatively expensive, the conductivity can be improved while controlling the corresponding cost by providing silver contacts on the elastic conductive spring. And since silver is relatively soft, the elastic conductive spring can deform the silver contacts to a certain extent when the elastic conductive spring is pressed, so as to increase the contact area with the outer surface of the conductive shaft, thereby improving the connection effect between the inductor coil and the conductive shaft, so as to further reduce the possibility of poor contact during use.
[0020] Preferably, the silver contact is protrudingly provided with a connecting rod, the connecting rod is riveted to the elastic conductive spring sheet, and the diameter of the connecting rod is smaller than the diameter of the silver contact.
[0021] By adopting the above technical solution, a connecting rod is protruded from the silver contact and the connecting rod is riveted to the elastic conductive spring. Since the diameter of the connecting rod is smaller than the diameter of the silver contact, the connection strength between the two can be improved after being deformed under pressure, thereby reducing the possibility of the silver contact falling off during use, thereby further reducing the possibility of poor contact during use.
[0022] In summary, the utility model has the following beneficial effects:
[0023] 1. Through the elasticity of the elastic conductive spring itself, it is closely in contact with the outer wall of the conductive shaft to improve the close contact with the conductive shaft to form a conductive loop. Compared with the welding process, it reduces the possibility of poor contact of the inductor coil during use.
[0024] 2. The elastic conductive spring is detachably connected to the contact link to facilitate replacement.
[0025] 3. By setting up silver contacts, since silver has good conductivity but is relatively expensive, the conductivity can be improved while controlling the corresponding cost. And since silver is relatively soft, the elastic conductive spring can increase the contact area with the outer surface of the conductive shaft when the elastic conductive spring is pressed, thereby improving the connection effect between the inductor coil and the conductive shaft, and further reducing the possibility of poor contact during use.

[0030] The following is combined with Figure 1-3 , further details of this application are given.
[0031] The embodiment of the present application discloses a contact ring assembly for an inductor.
[0032] Example:
[0033] A contact ring assembly for an inductor, referring to Figure 1 , Figure 2 , is coaxially arranged with the conductive shaft 1, and the sliding sleeve is arranged on the conductive shaft 1, and can slide along the length direction of the conductive shaft 1, and abut against the inductor 2 to connect the conductive shaft 1 and the inductor 2. It should be noted that the inductor 2 is arranged on the workbench 21, and the inductor 2 is arranged in a spiral shape. In this embodiment, the conductive shaft 1 rotates around the center of the inductor 2.
[0034] Reference Figure 2 , Figure 3 The contact ring assembly specifically includes a contact ring body 3 abutting against the inductor 2, a plurality of elastic conductive springs 4 wound on the contact ring body 3, and a silver contact 5 arranged on the elastic conductive spring 4. The contact ring body 3 is also made of a conductive material, such as copper, aluminum, etc., and is specifically set according to the needs. The contact ring body 3 is coaxially arranged with the conductive shaft 1, and the sliding sleeve is arranged on the conductive shaft 1. In this embodiment, the outer peripheral wall of the contact ring body 3 is provided with an annular slot 31 for inserting the inductor 2, and the cross section of the annular slot 31 along its axial direction is V-shaped. During the rotation of the conductive shaft 1, the position of the contact ring body 3 on the conductive shaft 1 can be changed along the spiral direction of the inductor 2.
[0035] The elastic conductive spring piece 4 is a copper elastic spring piece, which is conductive. In this embodiment, the elastic conductive spring piece 4 is detachably connected to the contact ring body 3. Specifically, one end surface of the contact ring body 3 is protrudingly provided with a mounting ring 32, which is coaxially sleeved on the conductive shaft 1. The elastic conductive spring piece 4 abuts against the outer peripheral wall of the mounting ring 32. The elastic conductive spring piece 4 is penetrated by a screw 41, which is specifically a hexagon socket screw 41. Two screws 41 are arranged at intervals along the width direction of the elastic conductive spring piece 4, and the screws 41 are threadedly connected to the mounting ring 32. The elastic conductive spring piece 4 abuts against the outer surface of the conductive shaft 1.
[0036] It should be noted that the diameter of the mounting ring 32 is smaller than the diameter of the contact ring body 3 and smaller than the diameter of the annular slot 31 , so as to reduce the possibility of the contact ring assembly colliding with the inductor 2 when moving on the conductive shaft 1 .
[0037] Among them, the silver contact 5 is protrudingly provided with a connecting rod 51, which is riveted to the elastic conductive spring 4. The diameter of the connecting rod 51 is smaller than the diameter of the silver contact 5. The silver contact 5 is specifically arranged at one end of the elastic conductive spring 4 away from the screw 41, and is arranged on the surface of the elastic conductive spring 4 close to the conductive shaft 1, so that under the elasticity of the elastic conductive spring 4, the silver contact 5 abuts against the outer surface of the conductive shaft 1.
[0038] The implementation principle of a contact ring assembly for inductance in an embodiment of the present application is as follows: since the contact ring body 3 is in contact with the inductor coil 2, the silver contact 5 is in close contact with the outer wall of the conductive shaft 1 through the elasticity of the elastic conductive spring 4 itself, so as to improve the close contact with the conductive shaft 1, and the main body is provided with an annular slot 31 for inserting the inductor coil 2, so as to improve the release with the conductive coil to form a conductive loop, compared with the welding process, so as to reduce the possibility of poor contact of the inductor coil 2 during use.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
