Description

Technical Field

[0001] The utility model belongs to the technical field of inductors, and in particular relates to an inductor capable of preventing accidental touch. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. Its structure is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance and only blocks changes in current. If no current flows through the inductor, it will attempt to block current from flowing through it when the circuit is connected. If current flows through the inductor, it will attempt to maintain the current constant when the circuit is disconnected. Inductors are also called chokes, reactors, and dynamic reactors.

[0003] Currently, four-pin separated inductors on the market usually have a magnetic core body and four solder pins directly welded to the bottom of the magnetic core body. A coil consisting of two groups of insulated copper wires is wound on the magnetic core body, and the two ends of the insulated copper wires are respectively connected to their corresponding solder pins.

[0004] Publication (Announcement) No. CN221175924U proposes an inductor that prevents accidental touch from occurring between the insulated copper wire and the solder pin and the circuit board, thereby affecting the circuit connection of the separated inductor.

[0005] However, when the above patent is in use, a spring structure is required to cooperate with an insulating pin for limiting the position. However, the position of the spring structure lacks an adjustable function, which may cause the device to be unable to be disassembled or the arc surface of the insulating pin can be freely plugged in and out of the device, resulting in poor limiting effect and affecting the fixing effect. In addition, the component structure of the anti-accidental touch component is inconvenient to maintain and disassemble, which increases the cost of equipment use and affects the efficiency of use. Utility Model Content

[0006] The technical problem to be solved by the present invention is that the component mechanism of the anti-mistouch component of the inductor in the prior art is inconvenient to operate and adjust, which affects the installation stability, and is inconvenient to disassemble and replace.

A mounting frame fixedly connected to the lower portion of the insulating base is formed by a vertical combination of two sets of rectangular plate-shaped structures and a circular disc structure.

[0009] A movable rod is slidably provided through the center of the disc structure on the mounting frame, and a limiting component plugged into the limiting groove is fixedly connected to the upper end of the movable rod; an adjusting unit is provided at the lower part of the mounting frame.

[0010] Furthermore, a return spring is sleeved on the movable rod, and the return spring is arranged between the limiting component and the mounting bracket.

[0011] Furthermore, the adjustment unit includes a connecting sleeve fixed to the lower part of the mounting frame, the inner ring of the connecting sleeve is provided with a threaded groove, a threaded column is screwed on the threaded groove, and an anti-accidental touch insulating plate is fixed to the lower part of the threaded column.

[0012] Furthermore, the inner diameter of the connecting sleeve is larger than the outer diameter of the movable rod, and the upper end of the threaded column is matched with the lower end of the movable rod.

[0013] Furthermore, the limiting member is arranged in a half spherical structure.

[0014] Furthermore, a coil is wound on the magnetic core body, and a movable groove having a size corresponding to the outer diameter of the magnetic core body is opened on the installation groove.

[0015] Furthermore, an avoidance groove is provided on the insulating base, and welding feet for welding the magnetic core body are passed through the lower part of the insulating base.

[0016] The beneficial effects achieved by the utility model using the above structure are as follows:

DETAILED DESCRIPTION

[0025] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model proposes an inductor for preventing accidental touch, including a magnetic core body 1, end plates 2 are fixedly connected at both ends of the magnetic core body 1, and a limiting slot 3 is provided at the center of the end plate 2. An insulating base 5 is provided below the magnetic core body 1, and a mounting groove 6 is provided on the side of the insulating base 5 for snap-fitting with the end plate 2. It also includes a circular groove 8 provided on the insulating base 5, and a mounting frame 9 is fixedly connected to the lower part of the insulating base 5. The mounting frame 9 is composed of two groups of rectangular plate structures and a disc structure vertically combined; a movable rod 10 is slidably provided through the center of the disc structure on the mounting frame 9, and a limiting member 11 is fixedly connected to the upper end of the movable rod 10 and plugged into the limiting slot 3; an adjustment unit is provided at the lower part of the mounting frame 9.

[0026] The adjustment unit includes a connecting sleeve 13 fixed to the lower part of the mounting frame 9. The inner ring of the connecting sleeve 13 is provided with a threaded groove 14. A threaded column 15 is screwed on the threaded groove 14. An anti-accidental touch insulating plate 16 is fixed to the lower part of the threaded column 15.

[0027] The inner diameter of the connecting sleeve 13 is larger than the outer diameter of the movable rod 10 , and the upper end of the threaded column 15 is matched with the lower end of the movable rod 10 .

[0028] It should be noted that the inner diameter of the connecting sleeve 13 is larger than the outer diameter of the movable rod 10, so that the movable rod 10 can pass through the inside of the connecting sleeve 13, which is convenient for adjustment and use. 10 can be locked and fixed by adjusting the height of 15.

[0029] Furthermore, the limiting member 11 is provided in a half spherical structure.

[0030] It should be noted that the hemispherical structure of the limiting member 11 facilitates push adjustment.

[0031] Furthermore, a coil 4 is wound on the magnetic core body 1 , and a movable groove 7 having a size corresponding to the outer diameter of the magnetic core body 1 is opened on the mounting groove 6 .

[0032] Furthermore, an avoidance groove 17 is formed on the insulating base 5 , and a welding foot for welding the magnetic core body 1 passes through the lower portion of the insulating base 5 .

[0033] When in use, the user installs and places the device, slides the end plate 2 on the installation groove 6, and the magnetic core body 1 slides over the movable groove 7. In the process of moving to the center position, the end plate 2 squeezes the arc surface of the limiting member 11, pushing the movable rod 10 down, and the return spring 12 is compressed. After moving into place, the limiting member 11 corresponds to the limiting groove 3. Under the push of the elastic potential energy of the return spring 12, the limiting member 11 is stuck in the limiting groove 3. At this time, the limiting effect is not good, and the threaded column 15 needs to be rotated on the threaded groove 14. As the threaded column 15 gradually moves up, the bottom of the movable rod 10 is lifted, so that the limiting member 11 cannot be easily moved down, resulting in the problem of loose structure.

[0034] The anti-accidental-touch insulating plate 16 contacts the circuit board and plays a limiting role, thereby preventing the portion where the insulated copper wire is connected to the solder pin from accidentally touching the circuit board, thereby affecting the circuit connection of the separation inductor.

[0035] The four insulated copper wires extending from the two sets of limiting grooves 3 wound around the magnetic core body 1 are connected to the solder pins. The insulated copper wires in the path are constrained in the avoidance grooves 17 opened on the circumference of the insulating base 5 to prevent the insulated copper wires from rubbing against other surrounding electronic components and causing accidental short circuits due to the insulation layer being worn away. The above is the entire usage process of an anti-accidental touch inductor.

[0036] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
