Abstract

The invention discloses an inductance element with a heat-shrinkable tubing and a preparing method of the inductance element, and relates to the technical field of electronic components. The inductance element comprises a core column, a coil and an electrode, the side wall and the end of the core column are covered with first heat-shrinkable tubing, the end of the first heat-shrinkable tubing is covered with second heat-shrinkable tubing, the second heat-shrinkable tubing is used for making the first heat-shrinkable tubing keep contact with the end of the core column, and the end, away from the electrode, of the core column is provided with a stopping cover which is detachably installed and is used for making the first heat-shrinkable tubing and the second heat-shrinkable tubing keep contact with the end of the core column. The preparing method comprises the preparing steps of filling processing, preheating processing, heat-shrinkable processing, glue dotting processing and the like. The heat-shrinkable tubing can be fixedly connected with the core column, in the using, storage or installation process of the heat-shrinkable tubing, covering of the core column can be maintained, and the integrity of the inductance components is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of electronic components, in particular to an inductance element with a heat shrinkable sleeve and a manufacturing method thereof. Background technique [0002] With the development of electronic technology, electronic components are gradually becoming smaller, lighter, high-frequency, large current, low electromagnetic interference, low manufacturing costs, and high reliability. Products are required to undergo rapid temperature changes and strong external impacts. Under the circumstances, the excellent performance can still be maintained. At present, there are many kinds of wire-wound power inductance components, most of which are simply protected by heat-shrinkable tubing. However, the existing heat-shrinkable tubing is only fixed on the electronic components by simple heat shrinkage, and it is easy to be subjected to external force. If it falls off or is damaged, the protection function of electronic compone...
