Place the tip of the
A method for attaching an actuator of a reed relay is characterized in that the actuator is detachably brought into contact with the upper surface of a fixed contact 1, and unnecessary parts of a metal plate 6 are punched out. To provide an actuator mounting method for a reed relay which is compact and inexpensive, has no inclination between a contact point and an actuator, has high operational stability and performance.

Conventional reed relays tend to be tilted between the fixed contacts and the actuator, which causes instability in durability, pressure resistance, contact bounce, contact resistance, etc., resulting in low operational stability and performance. However, there is a drawback that the assembly requires a sealing process and a potting process, making it complicated.

The present invention aims to eliminate such conventional drawbacks, and will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a block A includes a first fixed contact 1, a second fixed contact joint 2, a coil terminal 3, an actuator support 4, and another terminal plate 5 on a long metal plate 6.
A plurality of sets are successively formed by punching at regular intervals, and the first fixed contact 1 and the actuator support portion 4 are curved so that their upper end surfaces are located substantially in the same plane.

In this case, only a single block A may be formed on one metal plate 6.

Next, the block A of the metal plate 6 is used as a unit insert member and a frame 7 is insert-molded with synthetic resin as shown in FIG.
The upper end surfaces of the fixed contact 1 and the actuator support portion 4 are simultaneously finished so that the upper surfaces of both are located in the same plane.

Next, the permanent magnet 9 is fixed near the first fixed contact 1, and the first
, the second fixed contact 8 is welded and fixed to the second fixed contact joint part 2 while inserting a spacer with accurate dimensions between the second fixed contacts 1 and 8, and the spacer is inserted between the first and second fixed contacts 1 and 8. Set accurate spacing.

Next, the coil block 10 is inserted into the frame T, the lead terminals 11 and 11 are bonded and connected to the coil terminal parts 3, 3, and the actuator 12 is inserted into the coil block 10.
The ends of the actuator are placed over the upper surfaces of the actuator supports 4, 4 and fixed by welding.

The tip of this actuator 12 comes into elastic contact with the upper surface of the first fixed contact 1 in a detachable manner against the elasticity of the spring.

Thereafter, the shield plate 13 and the cover 14 are placed on top of the frame 7 as shown in FIG. At the same time, the first fixed contact 1 is removed by punching along the cotton.
, the second fixed contact joint portion 2, the coil terminal portion 3, the actuator support portion 4, and other portions of the terminal plate 5 that protrude outward from the frame 7 are bent downward to form a dual in-line terminal configuration.

In the reed relay obtained in this way, the actuator 12 serves as a common contact plate, and normally the tip of the actuator 12 is in contact with the first fixed contact 1, and when the coil block 10 is energized, the tip of the actuator 12 is connected to the second fixed contact.
The fixed contact 8 is brought into suction contact and conductive, and the contact is exchanged.

In the present invention, as described above, the first fixed contact, the actuator support portion, other terminal plates, etc. are punched out, and the first
The fixed contacts and actuator support are formed by insert molding a curved metal plate into a synthetic resin frame.
Each of the above members is fixed to the frame as a single metal plate,
Even if each member is minute, it is possible to arrange each member on the frame with accurate positioning and dimensional accuracy without causing positional deviation between each member. For example, the first fixed contact and actuator The positional accuracy of the mounting with the support part is accurate, and since the bent first fixed contact and the upper surface of the actuator support part are polished so that they are located in the same plane, the first fixed contact and the actuator support can be mounted on the same plane. The mutual positional accuracy of the upper surfaces of the parts can be set with extremely high precision, and the actuator can be mounted with high dimensional accuracy so that it is not tilted with respect to the first constant contact, and the electrical life and pressure resistance can be set with high precision. , contact bounce, contact resistance, and other characteristics are stabilized and improved.

Since the unnecessary parts of the metal plate are punched out and removed after each necessary part is housed and fixed in the frame, combined with the fact that the above-mentioned parts are insert-molded as a single metal plate, the cost is small. There is an advantage that a reed relay with high precision can be provided at low cost in terms of parts and processes.
