Reed relay

Abstract

The invention relates to a reed relay which comprises a bobbin, a first coil, a second coil and a reed switching unit, wherein the bobbin comprises two side walls arranged at an interval, a barrel wall which is around an axis and connected between the side walls, a partition wall which is protruded out of the barrel wall and arranged between the side walls, a first winding groove which is positioned between the partition wall and one side wall, a second winding groove which is positioned between the partition wall and the other side wall, an accommodating chamber which is communicated with the side walls and the barrel wall along the axis and a plurality of electrodes which are respectively arranged on the side walls; the first coil and the second coil are respectively wound on the first winding groove and the second winding groove and electrically connected with the electrodes respectively; and the reed switching unit is arranged in the accommodating chamber and is provided with a plurality of pins extending out of the bobbin.

Description

technical field [0001] The invention relates to a relay, in particular to a magnetic reed relay. Background technique [0002] China Taiwan Patent Application No. 94137648 discloses a reed relay. The reed relay adopts a single coil winding structure, and the finished product must meet the customer's needs. In terms of current and impedance, it is generally difficult to achieve the winding structure of a single coil, because when a thicker coil is used to meet the low driving current, it will increase the volume and cannot meet the size limit of miniaturization. Impedance increases when the coil is wound, so improvement is necessary. [0003] In addition, in terms of control, the control of a single coil is relatively simple, and the matched circuit only needs a single signal source to achieve it. However, when there are switch control requirements for multiple signal sources, only one switch change can not meet the use requirements. Contents of the invention [0004] The...
