FIG. 1 is a sectional view showing the internal structure of a conventional mercury reed relay, and FIG. 2 is a perspective view of the same, in which 1 is a mercury reed switch in which mercury 2 is sealed, and 3 is a terminal 4, 5 of the mercury reed switch 1. A contact terminal 6 connected to is a coil provided around the mercury reed switch 1, and the mercury reed switch 1 is operated by the action of the magnetic force generated when the coil 6 is energized. 7 is a coil terminal connected to each lead wire at the beginning and end of winding of the coil 6, respectively.

ル６も大きなものが必要となつた。 In the mercury reed relay 11 having such a configuration, the mercury reed switch 1 has no contact repulsion during operation compared to a dry contact, and has a large contact allowable current, but on the other hand, the mercury reed switch 1 cannot be turned ON/OFF via the mercury 2 between the contacts. Since the contact gap is large due to the mercury reservoir in the lower part, the impressed ampere turn of the mercury reed switch 1 becomes high, and the coil 6 that operates it also needs to be large.

A non-magnetic resin such as silicone resin is poured between the 23 and 23 to form a yoke and a case, and 23 is a magnetic resin that serves as a yoke and case. Powders with a size of 1 to 10 microns are mixed to form a powder or tablet-shaped molding material. The contact terminals 14 and the coil terminals 21 are provided on a frame 24 made of a magnetic material such as permalloy and shaped as shown in FIG. 6.

防止するためである。 In the thus assembled state, a non-magnetic resin 22 is poured between the winding frame 17 and the mercury reed switch 12 and solidified together. This is because the magnetic resin 23 is attached to the winding frame 17 and the mercury reed switch 1 during subsequent molding.
This is to prevent the mercury from flowing between the terminals 15 of the mercury reed switch 12 and creating a bypass of the magnetic path formed by the terminals 15 of the mercury reed switch 12.

リードリレーとする。 Further, the frame 24 assembled in this state is placed in a mold and molded, and the entire outer peripheral surface is sealed with magnetic resin. The tie bars in the frame 24 are cut off using a press die, and the contact terminals 14 and coil terminals 21 of the frame 24 are bent to form a mercury reed relay as shown in FIG.

与える。 When the coil 16 of this mercury reed relay is energized, the lines of magnetic force generated can more easily pass through the magnetic resin 23, which is a magnetic material, and the same effect as when a yoke is attached in all directions occurs, causing the lines of magnetic force generated in the coil 16 to pass through the magnetic resin 23, which is a magnetic material. To more efficiently supply mercury to a reed switch 12.

As described above, according to the mercury reed relay according to the present invention, the mercury reed switch and the coil provided around it are fixed together with non-magnetic resin, and the entire outer periphery of the integrated mercury reed switch and coil is made magnetic. By surrounding the powder with a magnetic resin that serves as a yoke and case, the lines of magnetic force generated by the coil pass through the magnetic resin, producing the same effect as when a yoke is attached in all directions, and more efficiently converting the lines of magnetic force into mercury. Since it can be applied to a reed switch, it can operate with less power, and the coil can be made smaller, which has the effect of making it more compact.
また、巻枠構造のコイルとすることができるた

により同時に多数個成形ができるために大量生産
できる効果がある。 Furthermore, since the coil can have a winding frame structure, the coil winding and finishing processes can be automated, and since the magnetic resin can be molded into a large number of pieces at the same time using a transfer mold press, mass production is possible.
更に、巻枠が水銀リードスイツチとコイルとの

できる効果がある。 Furthermore, since the winding frame insulates the mercury reed switch and the coil, quality can be stabilized, and since there is no need for a metal case or terminal board as in conventional methods, the weight is lighter and printing is easier. The structure enables high-density mounting on a board and is sealed with magnetic resin, so when mounted on a printed circuit board, it is easy to position the contact terminals and coil terminals in positions that are easy to maintain and inspect. There is an effect that can be done.
