なるきらいがある。2 is a cross-sectional view of a conventionally assembled relay, showing different methods of configuring the electrostatic shield. That is, on the surface of the cylindrical shaft core 10 of the coil winding frame 4 explained in FIG. A metal foil with a thickness of about 30 to 50 microns (μ) is applied to form the shield 11 (see the dotted line position in the figure), and the excitation coil is wound after this shield is applied. A coil 3 is formed insulated from the layer. Other details are the same as in FIG. 1. However, instead of the metal foil 11 in FIG. 2, a conductive paste may be afted and dried to form an equivalent electrostatic shield.0 However, In conventional reed relays, the electrostatic shielding method described above is troublesome due to the need for solder connections to ensure the connection between the metal foil or quaternary paste and the terminals of the assembled board, or the connection of the 7-wire circuit within the reed relay. However, it also has the disadvantage that connection reliability cannot be obtained. The conductive thin plate-molded shield shown by 5 in FIG. 1 is press-molded integrally with the terminal, so there is no problem in terms of connection (relay assembly), but it tends to be expensive.

(f) 発明の実施例
以下、第3図の実施例図に基づき、本発明の詳細な説明

静電遮蔽端子9が夫々配設される。In the figure, the same reference numerals are added to the assembly functional parts of the relay components that are equivalent to those in the conventional figure to facilitate mutual comparison. For example, the reed switch 1 is housed in the cylindrical shaft core portion 10 of the winding frame 4 and assembled at the shaft center position of the coil 3. Further, on the insulating substrate 6 of the assembly, an output terminal 7 for connecting the relay switch circuit, an input terminal/terminal 8 of the coil, and an electrostatic shielding terminal 9 between the relay output circuits are respectively arranged.

The insulating layer melts on the surface by heat treatment at about 80°C or higher,
There is an advantage that an insulating layer can also be formed on the shield surface of the winding.

The magnetic coil will be wound.

An electrostatic shielding function is obtained at the external terminal, so that noise propagation due to, for example, electrostatic coupling between the input circuit and the output circuit is completely blocked.
