Embodiment Construction

[0043] Hereinafter, a coil component according to an embodiment of the present invention will be described with reference to the drawings. The coil component of this embodiment is applied to a solenoid valve, for example.

[0044] A solenoid valve is used, for example, as a circuit element of various devices mounted on an automobile, and is sometimes covered for waterproofing and dustproofing. In such a solenoid valve, the conductive wire receives a large stress due to the difference in thermal expansion coefficient between the molding resin and the conductive wire. In particular, when miniaturization of the coil component is strongly demanded, if the conductive wire is used as an aerial wiring, there is a high possibility that the conductive wire will be disconnected.

[0045] Therefore, in the coil component of the present embodiment, the lead wire is not directly pulled from the terminal electrode to the coil portion. Specifically, the conductive wire from the terminal el...

Abstract

A coil component 1 such as a solenoid valve is provided with a wiring part 20 formed by winding a conducting wire 4 therearound, and terminal electrodes 3A, 3B having connection terminals 16A, 16B electrically connected to the conducting wire 4. A locking piece 15A is provided on the terminal electrode 3A on a side of a wiring part for the connection terminal 16A, a starting end part of the conducting wire 4 is locked to the locking piece 15A, and the conducting wire 4 is led up in a direction reverse to a direction in which the wiring part 20 is arranged at a predetermined position, is passed into the connection terminal 16A so as to be electrically connected to the connection terminal 16A, and further led up in the direction reverse to the direction in which the wiring part 20 is arranged at a predetermined position.

Description

technical field [0001] The present invention relates to a coil component which is used for a solenoid valve, an electromagnetic actuator, etc., and in particular to a coil component which is fully molded and sealed, and a method of manufacturing the coil component. Background technique [0002] For example, coil components installed in the engine room of a motor vehicle or sometimes directly exposed to the external environment, such as ABS coils, valves of air conditioners, or valves of washing machine devices, are strongly subjected to temperature, humidity, shock, and vibration. , or dust and other external environment. [0003] In this way, it is desired that the coil components used in harsh environments affected by various external environments have waterproof and dustproof functions. Accordingly, an overmolding method of covering the coil component with a molding resin is adopted. [0004] However, when the coil component is repeatedly subjected to thermal load, the ...
