Description

Technical Field

[0001] This utility model relates to the field of electronic components, and more specifically, to an inductor with protective functions. Background Technology

[0002] An inductor is a device that works based on the principle of electromagnetic induction. When current flows through a conductor, it generates a certain electromagnetic field around the conductor. This electromagnetic field in turn induces an effect on other conductors within the range of this electromagnetic field. The effect on the conductor that generates the electromagnetic field is called self-inductance, that is, the changing current in the conductor itself produces a changing magnetic field, which in turn affects the current in the conductor. The effect on other conductors within the range of this electromagnetic field is called mutual inductance.

[0003] An inductor typically consists of an insulating sleeve, a magnetic core inside the insulating sleeve, a coil wound around the outside of the insulating sleeve, support baffles on both sides of the insulating sleeve, and probes extending from both ends of the coil. The coil is generally made of copper wire. Because copper wire is thin, it is very easy to bump and break it when workers handle it, causing damage. This also makes it difficult for workers to handle the inductor. Utility Model Content

[0004] The problem solved by this invention is how to provide an inductor with protective function that can protect the inductor coil and prevent the copper wire from being damaged during handling.

[0005] To address the aforementioned problems, this utility model provides an inductor with protective functionality, comprising: a base, an inductor frame, and a protective shell. The inductor frame includes a sleeve and support baffles disposed on both sides of the sleeve. A magnetic core is disposed inside the sleeve, and a coil is wound around the outside of the sleeve. The support baffles include a first baffle connected to the side of the sleeve and a first base plate located at the bottom of the first baffle and perpendicular to the first baffle. A wiring mechanism and a metal connecting piece are disposed in the middle of the first base plate. The first base plate has a metal connecting piece inside, with a first side of the metal connecting piece located below the wiring mechanism and a second side extending out of the inner side of the first base plate. The two leads of the coil are respectively welded to the extended ends of the metal connecting pieces on the inner sides of the two support baffles. The bottom of the protective shell is fixed to the base, and its inner side is in contact with the sides of the two support baffles, enclosing the coil.

[0006] Furthermore, the wiring mechanism includes an opening located on the outer side of the center of the first base plate, and a wire pressing component located above the opening.

[0007] Furthermore, the pressure wire component includes a first threaded hole provided in the first base plate, a first screw passing through the first threaded hole and entering the opening, a pressure wire piece provided on the first side of the first screw located inside the opening, and a first nut provided on the second side located outside the first base plate.

[0008] Furthermore, the first base plate is also provided with skeleton fixing holes.

[0009] Furthermore, the protective housing includes a top plate, side plates, and a bottom plate. The two side plates are respectively vertically arranged on the left and right sides of the top plate, and the bottom plate is vertically arranged on the bottom outer side of the side plates. When the bottom plate is fixed to the base, the top plate is attached to the top surface of the support baffle, and the two side plates are respectively attached to the two sides of the support baffle.

[0010] Furthermore, ventilation grilles are spaced apart on the top plate and side plate of the outer casing, and a protective net is provided on the surface of the ventilation grilles.

[0011] Furthermore, the bottom plate of the outer casing is provided with outer casing fixing holes.

[0012] Furthermore, four limiting blocks are sequentially arranged at the four corners of the base. A second threaded hole is provided between the first limiting block and the fourth limiting block, and between the second limiting block and the third limiting block. The second threaded hole corresponds to the position of the frame fixing hole. A third threaded hole is provided between the first limiting block and the second limiting block, and between the third limiting block and the fourth limiting block. The third threaded hole corresponds to the position of the outer shell fixing hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By fixing the frame to the base and setting a protective cover, a closed space is formed between the base plate, the support baffles on both sides of the inductor frame, and the protective cover, enclosing the coil inside. At the same time, the leads at both ends of the coil are connected by connecting pieces set in the base of the support baffle, so that the coil and its leads will not come into contact with the outside when the staff handles them, avoiding damage to the copper wires of the coil and making it convenient for the staff to handle.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1As shown, this utility model provides an inductor with protective function, including: a base 1, an inductor frame and a protective shell 2. The inductor frame includes a sleeve 3 and support baffles 5 disposed on both sides of the sleeve 3. A magnetic core is disposed inside the sleeve 3, and a coil 4 is wound around the outside of the sleeve 3. The support baffles 5 include a first baffle 51 connected to the side of the sleeve 3 and a first base plate 52 located at the bottom of the first baffle 51 and disposed perpendicular to the first baffle 51. A wiring mechanism 54 and a metal connecting piece 53 are disposed in the middle of the first base plate 52. The first base plate 52 has a metal connecting piece 53 inside. The first side of the metal connecting piece 53 is located below the wiring mechanism 54, and the second side extends out of the inner side of the first base plate 52. The two leads of the coil 4 are respectively welded to the extended ends of the metal connecting pieces 53 on the inner sides of the two support baffles 5. The bottom of the protective shell 2 is fixed to the base 1, and the inner side is attached to the sides of the two support baffles 5, covering the coil 4.

[0026] It should be noted that by fixing the frame to the base 1 and setting a protective cover, a closed space is formed between the base plate, the support baffles 5 on both sides of the inductor frame, and the protective cover, enclosing the coil 4 inside. At the same time, the leads at both ends of the coil 4 are connected by the connecting piece set in the base 1 of the support baffle 5, so that the coil 4 and its leads will not come into contact with the outside when the operator handles it, avoiding damage to the copper wires of the coil 4. When the operator handles it, they can directly touch the protective shell to pick it up without worrying about touching the copper wires or pulling out the probes, which facilitates the operation.

[0027] In one embodiment of the present invention, the wiring mechanism 54 includes an opening 541 located on the outer side of the center of the first base plate 52, and a wire pressing component located above the opening 541.

[0028] It should be noted that, as Figure 2 As shown, the opening 541 is used for the entry of external connection wires. The external connection wires are connected to the metal connecting piece 53 by the wire clamping component to realize the circuit connection with the inductor coil 4. The width of the metal connecting piece 53 can match the width of the opening 541.

[0029] In one embodiment of the present invention, the wire pressing component includes a first threaded hole disposed on the first base plate 52, a first screw 542 passing through the first threaded hole and entering the opening 541, a wire pressing piece 543 disposed on the first side of the first screw 542 located inside the opening 541, and a first nut 544 disposed on the second side located outside the first base plate 52.

[0030] It should be noted that, as Figure 2 and 3As shown, the first side of the metal connecting piece 53 is located below the wire pressing piece 543. By rotating the first nut 544, the first screw 542 is pressed down, and the wire pressing piece 543 can press the external connecting wire onto the metal connecting piece 53.

[0031] In one embodiment of the present invention, the first base plate 52 is further provided with a skeleton fixing hole 55.

[0032] It should be noted that the frame fixing holes 55 are used for fixing the first base plate 52 and the base 1, such as... Figure 3 As shown in the figure, there are two skeleton fixing holes 55, which are respectively set on the left and right sides of the first base plate 52. Other numbers of skeleton fixing holes 55 can also be used.

[0033] In one embodiment of this utility model, the protective shell 2 includes a top shell plate 21, a side shell plate 22, and a bottom shell plate 23. The two side shell plates 22 are respectively vertically arranged on the left and right sides of the top shell plate 21, and the bottom shell plate 23 is vertically arranged on the bottom outer side of the side shell plates 22. When the bottom shell plate 23 is fixed to the base 1, the top shell plate 21 is attached to the top surface of the support baffle 5, and the two side shell plates 22 are respectively attached to the two sides of the support baffle 5.

[0034] It should be noted that, as Figure 4 As shown, when the bottom plate 23 of the outer casing is fixed on the base 1, the two sides of the top plate 21 of the outer casing are respectively attached to the top surfaces of the two support baffles 5, forming a closed space at the top. The two sides of a side plate 22 of the outer casing are respectively attached to the sides of the two support baffles 5 on the same side, forming a closed space at the front and back sides of the space. This makes the bottom plate, the two support baffles 5 of the inductor frame and the protective cover form a closed space, enclosing the coil 4 inside.

[0035] In one embodiment of the present invention, ventilation grilles 24 are provided at intervals on the top plate 21 and the side plate 22 of the outer shell, and a protective net is provided on the surface of the ventilation grilles 24.

[0036] It should be noted that, as Figure 4 As shown, the ventilation grille 24 is used to allow ventilation in the enclosed space, and the protective net can be made of steel wire mesh, etc., to prevent small debris from entering through the space between the grilles.

[0037] In one embodiment of this utility model, the outer shell base plate 23 is provided with an outer shell fixing hole 25.

[0038] It should be noted that the outer casing fixing hole 25 is used for fixing the outer casing base plate 23 and the base 1.

[0039] In one embodiment of this utility model, four limiting blocks are sequentially arranged at the four corners of the base 1. A second threaded hole 15 is provided between the first limiting block 11 and the fourth limiting block 14, and between the second limiting block 12 and the third limiting block 13. The second threaded hole 15 corresponds to the position of the frame fixing hole 55. A third threaded hole 16 is provided between the first limiting block 11 and the second limiting block 12, and between the third limiting block 13 and the fourth limiting block 14. The third threaded hole 16 corresponds to the position of the outer shell fixing hole 25.

[0040] It should be noted that, as Figure 5 As shown, the height of the limiting block is slightly less than the thickness of the first base plate 52 and the outer shell base plate 23. When fixed, the first limiting block 11 and the fourth limiting block 14, the second limiting block 12 and the third limiting block 13 limit the installation of the two support baffles 5. Their spacing matches the width of the first base plate 52, and the length of the limiting block matches the length of the part of the first base plate 52 that extends out of the first baffle 51. The first limiting block 11 and the second limiting block 12, the third limiting block 13 and the fourth limiting block 14 limit the outer shell base plate 23. Their spacing matches the width of the outer shell base plate 23. The number and position of the second threaded hole 15 correspond to the number and position of the frame fixing hole 55, and the number and position of the third threaded hole 16 correspond to the number of the outer shell fixing hole 25. So that when fixed, the fixing screw can pass through the frame fixing hole 55 and the outer shell fixing hole 25 and enter the second threaded hole 15 and the third threaded hole 16 to fix the inductor frame and the protective shell 2.

[0041] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
