Description

Technical Field

[0001] The utility model relates to the technical field of chip inductors, in particular to a chip inductor. Background Art

[0002] Chip inductors, also known as surface mount inductors, are a new generation of leadless or short-lead microelectronic components suitable for surface mount technology (SMT). Chip inductors are electromagnetic induction components wound with coils. Their main function is to isolate and filter AC signals, or form resonant circuits with capacitors, resistors, etc. When the current flowing through the chip inductor changes, it will generate a magnetic field, and the magnetic flux of this magnetic field will act on the circuit.

[0003] When chip inductors are used for a long time, the internal coils are prone to overload conditions such as overcurrent operation, overheating, frequent starting or braking, etc., which can easily cause combustion. In addition, if there are quality problems with the inductor coil itself, such as broken enameled wire, short circuit between turns, etc., it may also cause the coil to burn. If the fire cannot be extinguished in time after burning, it may easily lead to greater losses, so there are certain shortcomings. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] Some embodiments of the present invention are described below in conjunction with the accompanying drawings to provide a chip inductor.

[0027] Embodiment 1:

[0028] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a chip inductor, including a shielding cover 100, an inductor assembly 200, a screw 300, a storage cloth 500, a fire extinguishing dry powder 600, a top cover 700 and a bottom cover 800.

[0029] Specifically, the shielding cover 100 includes a cover body 101 and a stopper 102 arranged on the inner side of the cover body 101. The stopper 102 has a blocking effect to facilitate the fixing of the storage cloth 500. Both sides of the cover body 101 are provided with mounting holes 1011 for fixing the inductor component 200. The mounting holes 1011 can be penetrated by the screws 300 to fix the inductor component 200.

[0030] Specifically, the inductor component 200 is arranged inside the shielding cover 100. The inductor component 200 includes a magnetic core 201 arranged inside the cover body 101, a coil 202 wound around the outside of the magnetic core 201, and a conductive metal sheet 203 arranged on the coil 202. When the current flowing through the inductor component 200 changes, it will generate a magnetic field. The magnetic flux of this magnetic field will act on the circuit, and its function is mainly to isolate and filter the AC signal, or form a resonant circuit with capacitors, resistors, etc.

[0031] Specifically, the two screws 300 pass through the cover body 101 and are threadedly connected to the magnetic core 201 . The two screws 300 can fix the magnetic core 201 on the cover body 101 for easy installation.

[0032] Specifically, the storage cloth 500 is bonded to the top of the block 102, and a plurality of grooves 501 are provided on the storage cloth 500. The grooves 501 can be used to place the fire extinguishing dry powder 600, that is, the fire extinguishing dry powder 600 can be evenly distributed for rapid fire extinguishing. The storage cloth 500 is woven from viscose fiber, which can burn quickly so that the fire extinguishing dry powder 600 can quickly cover the inductor component 200.

[0033] Specifically, the fire extinguishing dry powder 600 is placed on the top of the storage cloth 500 , and the fire extinguishing dry powder 600 can cover the inductor component 200 to extinguish the fire by isolating oxygen.

[0034] Specifically, the top cover 700 is screwed to the top of the shielding cover 100 , and the top cover 700 can cover the top of the shielding cover 100 for sealing.

[0035] Specifically, the bottom cover 800 is screwed to the bottom of the shielding cover 100 , and the bottom cover 800 can cover the bottom of the shielding cover 100 for sealing.

[0036] Embodiment 2:

[0037] Reference Figure 1 and Figure 2 , which is the second embodiment of the utility model, and is different from the first embodiment in that it also includes a guide plate 400, and two guide plates 400 are symmetrically arranged on the inner side of the cover body 101. The guide plates 400 can guide the magnetic core 201 for quick installation.

[0038] The working principle and use process of the utility model are as follows: when in use, the inductor component 200 is first placed in the shielding cover 100. During the placement process, the magnetic core 201 can be guided by the guide plate 400 for quick installation. When the magnetic core 201 is in a suitable position, it can be fixed to the cover body 101 by the screw 300, and then the storage cloth 500 can be bonded to the block 102. After bonding, the fire extinguishing dry powder 600 is placed on the top of the storage cloth 500. After placement, the top cover 700 and the bottom cover 800 are fixed to the cover body 101 by screws. When the inductor component 200 burns, it will burn the storage cloth 500. After burning, the fire extinguishing dry powder 600 on the top will all fall off, and the fallen fire extinguishing dry powder 600 will cover the inductor component 200, so that the fire can be extinguished quickly, which greatly reduces the loss. When extinguishing the fire, since the groove 501 can be used to place the fire extinguishing dry powder 600, the fire extinguishing dry powder 600 can be evenly distributed for quick fire extinguishing.
