Description

[Detailed description of the invention] The present invention relates to reed relays.

In conventional reed relays, resin is injected between the metal case and the assembly after the internal components are assembled to prevent outside air from entering the relay body, but the injection molding process cannot be mechanized, making assembly complicated. The injected liquid corroded the coil when used for a long time, causing wire breakage.

Furthermore, the terminal groups protruding from the bottom surface are not aligned, making handling complicated.

The present invention aims to eliminate the above-mentioned drawbacks, provide a reed relay that is easy to assemble, allows terminal groups to be aligned, and allows the terminal arrangement to be arbitrarily changed.

The invention will now be explained with reference to the drawings.

As shown in FIGS. 1 to 3, 1 and 2 are coil frames that are joined together to form a coil frame, and fixed terminals 5 and 6 are simultaneously molded on the enlarged portion 3.4 on the minus side, respectively. the fixed terminal 5,
The contact portions 5a and 6a of No. 6 are provided so as to face each other with a suitable contact gap when the coil frame halves 1 and 2 are joined.

Reference numeral 7 denotes a protrusion formed on the enlarged part 3, which is provided so as to be able to fit into the recess 8 of the enlarged part 4, and has a protrusion 9° 9 opposite thereto which abuts against the contact part 6a to ensure a contact gap. has been done.

Reference numeral 10 denotes a common terminal that is simultaneously molded on the enlarged portion 11 on the other side of the coil frame half 1, and one end of the lead 14 is housed between the recesses 12 and 13 extending in the longitudinal direction of the coil frame halves 1 and 2. It will be permanently installed.

The free end of the lead 14 is formed to reach between the contact portions 5a and 6a, that is, the contact gap, and to come into contact with one of the contact portions 5a.

15. 15 is a protrusion, which is the enlarged part 1 on the other side of the coil frame half 2.
It joins with the 6-shaped step 17.17.

18.19. %- and 20.21 are coil frame halves 1 and 2
Coil terminals are simultaneously molded on the enlarged portions 3, 4, 11, and 16 on both sides, 22 is a coil wound around the joined coil frame, and 23 is a magnet disposed between fixed terminals 5 and 6. .

24 is a base flock, and a pair of fixed terminal portions 25, 26. two pairs of coil terminal portions 27 to 30, and a common terminal portion 31 are simultaneously molded to form a button that aligns and protrudes from both sides in the horizontal direction. , the fixed terminals 5 and 6 protruding from the bottom surfaces of the joined coil frame halves 1 and 2, the coil terminals 18, 19 buttons and 20, 21, and the lower ends of the common terminal 10 are inserted and brought into contact with the terminal group. Obtaining holes 32.33, 34.35, 36
There are 37 trigrams and 38 trigrams.

39 is a yoke, and 40 is a case that can be mounted on the base block.

According to the present invention, the coil frame halves 1 and 2 are assembled, joined together, and ultrasonically welded; and the terminal groups 5 are inserted into the holes 32 to 38 of the base block 24.

6. Insert the wires 18, 19, 20, 21, and 10, make them contact with each terminal part 25 to 31, and ultrasonically weld the bottom of the coil frame 1°2 to the base block 24, and then place it on the base flock 24. A case 40 is mounted and ultrasonically welded.

Thereafter, the horizontally extending terminals are uniformly bent vertically downward from appropriate locations to complete the assembly.

The reed relay of the present invention constructed as described above has the following features: (a) It is easy to assemble, and does not cause corrosion of the windings, etc.
It can protect the windings and prevent outside air from entering inside.

b. It has a group of matched terminals and is easy to handle.

C is extremely easy to encapsulate.

d) Each terminal extending in the horizontal direction can be bent from the required position, allowing the terminal arrangement of the relay to be changed arbitrarily, providing excellent versatility.

and other effects.
