Description

[Detailed description of the invention] The present invention relates to a method for manufacturing a reed relay.

Conventionally, in order to manufacture reed relays, multiple terminal insertion holes were formed in a synthetic resin frame, and a terminal board was passed through each of the terminal insertion holes, and the assembly was performed using a potting process, which took time and effort. However, in the conventional example described above, the fixed position of the terminal plate shifts or tilts within the terminal insertion hole, and as a result, the correct position of the frame is not correct. There was a problem that each member could not be attached and the accuracy of the distance between each member was poor.

The present invention was invented in view of the above-mentioned conventional drawbacks, and its purpose is to provide a fourth fixed contact, a second fixed contact joint, a coil terminal, an actuator support, and other terminal boards. By insert-molding the parts into a synthetic resin frame simultaneously as one block, it is possible to accurately attach each part to the predetermined position of the frame at the same time as the frame is molded, without causing misalignment or tilting, and also to attach each part to the frame. To provide a method for manufacturing a reed relay that can be easily manufactured by attaching the reed relay at one time, and can be manufactured by continuous manufacturing.

The method for manufacturing a reed relay of the present invention is such that the first fixed contact 1, the second fixed contact joint 2, the coil terminal part 3, the actuator support part 4, and the other terminal plate 5 are punched out, and the first fixed contact 1 and the actuator are punched out. A plurality of blocks A each having a bent support portion 4 are formed on a metal plate 6, each block is insert-molded into a synthetic resin frame 7, and the metal plate 6 is
This method is characterized by punching out and removing unnecessary portions of the material, and by using such a method, the above-mentioned object of the present invention is achieved.

Hereinafter, the present invention will be explained in detail based on the attached drawings. As shown in FIG.
A plurality of blocks A each including a set of terminal plates 5 and other terminal plates 5 are continuously formed by punching at regular intervals, and the first fixed contact 1 and the actuator support part 4 are arranged so that their upper end surfaces are located in substantially the same plane as each other. Form.

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 their upper surfaces are located in the same plane.

This insert molding may be performed sequentially for each block, or may be performed on a plurality of blocks at the same time.

Next, the permanent magnet 9 is fixed near the first fixed contact 1, and the straw 1
, the second fixed contact 8 is welded and fixed to the second fixed contact joint part 2 while inserting a spacer of accurate size between the second fixed contacts 1°8, and the second fixed contact 8 is fixed between the first and second fixed contacts 1 and 8. Set precise spacing.

Next, the coil block 10 is inserted into the frame γ, 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 end of the actuator support section 44 is placed over the upper surface of the actuator support section 44 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. The first fixed contact 1 is removed by punching along the line
, 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 second fixed contact joint, the coil terminal part, the actuator support part, and the other terminal plates are punched out, and the first fixed contact and the actuator support part are bent. A plurality of blocks are molded onto a metal plate, each block is insert-molded into a synthetic resin frame, unnecessary parts of the metal plate are punched out, and a second fixed contact is then fixed to the second fixed contact joint. At the same time, since the end of the actuator is fixed to the actuator support, each member such as the first fixed contact, the second fixed contact joint, the coil terminal, the actuator support and other terminal plates is molded into a frame using synthetic resin. At the same time, it can be attached to the frame as one block,
Each component can be attached to the frame at once, making manufacturing easier. Furthermore, since each component is inserted into the frame as one block, each component can be accurately attached to the specified position of the frame without shifting or tilting. This has the advantage that each member can be arranged on the frame with accurate positioning and dimensional accuracy.

What's more, after all the required parts are fixed to the frame, unnecessary parts of the metal plate block are punched out and removed.

As mentioned above, the above-mentioned members are insert-molded in the form of a single metal plate, and this has the advantage that a highly accurate reed relay can be provided at low cost with a small number of parts and processes.

Furthermore, as mentioned above, multiple blocks made of each member are formed on a metal plate and these blocks are used for insert molding, so the unnecessary parts of the metal plate are reduced and a large number of reed relays can be manufactured with a small number of parts. It has the advantage of being able to efficiently and continuously produce products.
