Description

Technical Field

[0001] This utility model belongs to the field of inductor coil technology, and in particular relates to an inductor coil frame. Background Technology

[0002] An inductor is a device that works based on the principle of electromagnetic induction. When current flows through a conductor, a certain electromagnetic field is generated around the conductor. This electromagnetic field in turn induces a reaction in other conductors within the range of the electromagnetic field. This effect on the conductor that generates the electromagnetic field is called self-induction. An inductor is an electromagnetic induction element made of insulated wire. It is generally composed of a frame, windings, shielding, encapsulation material, magnetic core or iron core, etc. Some larger fixed inductors or adjustable inductors mostly have enameled wire wound around the frame, and then the magnetic core or copper core, iron core, etc. are installed in the inner cavity of the frame to increase its inductance. Therefore, the frame plays an important role in the inductor.

[0003] However, existing technologies have some problems: in order to obtain different inductance values, existing inductor coil frames usually need to be manufactured in different specifications according to the requirements. However, commonly used frames cannot be adjusted during use, resulting in high manufacturing costs, poor versatility, reduced practicality of inductor coil frames, and inconvenience for users. Therefore, we propose an inductor coil frame. Utility Model Content

[0016] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0017] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] Example 1: like Figures 1 to 2 As shown in the figure, an inductor coil frame provided by this utility model includes a first mounting base 1 and a second mounting base 4 corresponding to the first mounting base 1. A connecting base 2 is fixedly connected to the side of the first mounting base 1 opposite to the second mounting base 4. The connecting base 2 is provided with a through hole 24 and a plurality of insertion slots 23 on the side near the second mounting base 4. The insertion slots 23 are symmetrically distributed at the four corners of the connecting base 2. A screw sleeve 43 and a plurality of insertion plates 42 are fixedly connected to the side of the second mounting base 4 near the connecting base 2. The insertion plates 42 extend into the insertion slots 23. The screw sleeves 43 correspond to the through holes 24. An adjustment mechanism 3 is provided on the outside of the first mounting base 1. The adjustment mechanism 3 passes through the through hole 24 and is connected to the screw sleeve 43. The rectangular insertion slots 23 symmetrically distributed at the four corners of the connecting base 2 and the T-shaped grooves of the second mounting base 4 are connected to the connecting base 4. The shaped plug plate 42 forms a surface contact fit to achieve positioning in the X / Y axis direction, effectively preventing coil winding deviation caused by the tilt of the mounting seat; and the coaxiality design of the screw sleeve 43 and the through hole 24 of the connecting seat 2 ensures the thread fit accuracy when the adjustment mechanism 3 passes through. Rotating the knob 32 can realize stepless adjustment of the distance between the two mounting seats, which is compatible with the winding of inductor coils of different heights and improves the applicability of the device.

[0019] like Figure 2As shown, the right outer wall of the second mounting base 4 is provided with a polygonal groove 41, which is located behind the screw sleeve 43 and is interconnected. The adjustment mechanism 3 includes a screw shaft 33 located on the outside of the first mounting base 1 and a nut 31 embedded in the polygonal groove 41. The screw shaft 33 is threaded to the screw sleeve 43 through the through hole 24, and the screw shaft 33 extends into the polygonal groove 41 and is threaded to the nut 31. A knob 32 is fixedly connected to one end of the screw shaft 33 located outside the first mounting base 1. The polygonal groove 41 of the second mounting base 4 and the embedded nut 31 are precisely matched to form an anti-rotation limiting pair to prevent the nut 31 from rotating synchronously when the screw shaft 33 is adjusted, thus ensuring the unidirectional controllability of the adjustment operation.

[0020] like Figures 3 to 4 As shown, the upper and lower end faces of the connecting seat 2 are provided with inwardly recessed sliding grooves 21. The lower end of the sliding groove 21 is provided with an interconnected connecting groove 22. The connecting groove 22 is interconnected with the insertion groove 23, and the cross-sections of the sliding groove 21 and the connecting groove 22 are arranged in a T-shape. The connecting groove 22 is provided with a T-shaped positioning block 5. The positioning block 5 extends into the insertion groove 23 and connects with the insertion plate 42. The T-shaped sliding groove 21 and the connecting groove 22 on the upper and lower end faces of the connecting seat 2 form a three-dimensional limiting guide with the T-shaped positioning block 5. The positioning block 5 extends into the insertion groove 23 and is rigidly connected to the insertion plate 42, realizing positioning in the Z-axis direction, solving the problem of vertical swaying that is easy to occur in traditional planar connections, and at the same time facilitating the movement of the insertion plate 42 within the insertion groove 23.

[0021] like Figure 1 , Figure 5 and Figure 6As shown, the positioning block 5 is fixedly connected to a positioning shaft 51 at one end inside the insertion slot 23, and a receiving hole 511 is provided through the outer wall of the positioning shaft 51; a limiting hole 421 is provided through the upper outer wall of the insertion plate 42, and the limiting hole 421 is used to receive the positioning shaft 51; a stepped hole 424 is provided on the inner wall of the insertion plate 42, and the left side of the stepped hole 424 communicates with the limiting hole 421. A telescopic block 422 arranged in a T-shape is connected inside the stepped hole 424, and one end of the telescopic block 422 located inside the stepped hole 424 is connected to a spring. Spring 423, with one end connected to the inner wall of stepped hole 424, and telescopic block 422 extending to the inside of limiting hole 421; the positioning shaft 51 at the front end of positioning block 5 forms an interference fit with the limiting hole 421 of plug plate 42, improving the relative position accuracy of the two mounting seats, meeting the stringent requirements of high-frequency inductors for coil coaxiality, reducing the risk of inter-turn short circuit, and the storage hole 511 on the outer wall of positioning shaft 51 provides space for telescopic block 422 to avoid wear of positioning shaft 51 caused by rigid contact; under the action of spring 423, T-shaped telescopic block 422 on the inner wall of plug plate 42 normally extends into limiting hole 421, forming an elastic clamp with the outer wall of positioning shaft 51. When positioning shaft 51 is inserted, telescopic block 422 is compressed and retracted, and the potential energy of spring 423 is converted into contact surface pressure, automatically compensating for the tolerance gap between positioning shaft 51 and limiting hole 421, preventing positioning shaft 51 from loosening under vibration environment. The telescopic block 422 has an arc-shaped front end, which makes it easy for the telescopic block 422 to be inserted into the storage hole 511, so that installation can be completed quickly even in a narrow space where the view is obstructed.
