Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to an alloy magnetic rubber inductor. Background Art

[0002] Magnetic rubber inductors are also called automated shielded inductors because they are made using fully automated machines. Japan's Taiyo Yuden was the first to launch this product, so many people are accustomed to calling it NR inductor.

[0003] The prior art patent document with publication number CN203397870U provides a magnetic glue inductor, including a magnetic core and a coil, at least one turn of the coil is wound on the magnetic core, the outer periphery of the coil is wrapped with a magnetic glue layer, and a terminal component is arranged at the bottom of the magnetic core; the utility model forms a layer of magnetic glue by coating magnetic glue on the outer periphery of the coil, so that the magnetic glue inductor has strong resistance to drop impact and is durable; the closed magnetic circuit structure design has less magnetic leakage; under the condition of equal inductance, thicker copper wire can be used and fewer turns can be wound to increase the current, thereby obtaining a magnetic glue inductor with better reliability and stability.

[0004] However, in the process of using the existing alloy magnetic rubber inductors, most of them are welded to the circuit board with solder. When the alloy magnetic rubber inductor is damaged and needs to be replaced, the staff needs to remove the solder before disassembling it. However, this replacement method has cumbersome operation steps, which makes it inconvenient for the staff to replace it. For this reason, we propose an alloy magnetic rubber inductor.

[0014] (III) Beneficial effects

[0015] The utility model provides an alloy magnetic rubber inductor, which has the following beneficial effects:

[0016] (1) This alloy magnetic rubber inductor has a connection post, a shrinkage slot and a shrinkage card. When the coil is damaged and needs to be replaced during use, the staff uses a tool to forcefully pull the core top seat upwards. At this time, the shrinkage card will shrink into the shrinkage slot, and the core body will move out of the docking port, thereby separating the core base from the core top seat. Then, the core body to be replaced is aligned in the docking port, and the two ends of the coil are respectively located between the two connection posts and the extrusion block. Then, the core top seat is pressed downward with force. At this time, the shrinkage card will shrink into the shrinkage slot, so that the shrinkage card is located in the bayonet and connected. At the same time, the connection post and the extrusion block will clamp the two ends of the coil, and the coil can be replaced. This structural setting does not require the solder to be removed for replacement, thereby simplifying the replacement steps, making it convenient for the staff to replace the alloy magnetic rubber inductor.
