とができる。 The case 4 is a cylindrical case body 2 with an open bottom surface.
6 and a bottom plate 27 that closes the opening thereof, and when the bottom plate 27 is removed, the switch stand is inserted into a cylindrical switch housing tube 28 that projects from the center of the inner surface of the top wall of the case body 26. 1
The second plate-shaped main body portion 14 is fitted into the housing tube portion 28 so as to pass along the central axis thereof, and the tapered portion 18 of the portion to be melted 16 is brought into contact with the opening of the switch housing tube portion 28 . In this state, the entire melted part 16, the inner surface of the lid body 17, and the inner circumferential surface and end surface of the opening of the switch accommodation tube part 28 are melted by ultrasonic heating, and the switch stand 12 is pushed in, and the inner surface of the lid body 17 is housed in the switch. The switch stand 12 is welded to the switch accommodation pipe part 28 so as to abut against the end face of the opening of the pipe part 28. In this case, the molten resin of the melted part 16 fills the gap between the lid part 17 and the switch housing tube part 28, so that the two parts 17 and 28 can be brought into close contact with each other.

In addition, the switch housing tube section 28
The inside can be kept oil-tight by the lid body part 17. Thus, inside the switch accommodation tube section 28, the plate-shaped main body section 14 accommodates a substantially semi-cylindrical first chamber C1 in which the reed switch 5 is accommodated, and the terminals of the respective lead wires 81 and 82 are accommodated. It is divided into a second chamber C2 which is also approximately cylindrical.

る。 After the switch stand 12 is welded to the switch accommodation tube 28 as described above, the float 7 is loosely fitted around the outer circumference of the tube 28, the opening of the case body 26 is closed by the bottom plate 27, and both 26 and 27 are welded together by ultrasonic welding. . An annular platform 29 is provided on the inner surface of the bottom plate 27, which restricts the lowering limit of the float 7. When the float 7 is located between the lowering limit and a position slightly higher than the lowering limit, the magnet 6
This causes the reed switch 5 to close.

必要はなくなり構造の簡素化に寄与し得る。 As described above, according to the present invention, there is provided a case having a cylindrical switch housing tube portion extending in the vertical direction and communication holes located at the upper and lower portions, a reed switch fixed within the switch housing tube portion, and a case for housing the switch. In a liquid level detector comprising a float that is loosely fitted around the outer periphery of a pipe section and has a magnet on the inner peripheral surface that can actuate the switch when it approaches the reed switch, the center of the pipe section is located within the switch housing pipe section. a plate-shaped main body part that is fitted along the axis and divides the interior of the switch housing tube into first and second chambers each having a substantially semi-cylindrical shape; A switch stand is constituted by a lid part welded to the open end of the accommodation tube part, and the first chamber includes the lead which is fitted into a switch accommodation groove recessed on one side of the plate-shaped main body part. A switch is disposed, and the tips of a pair of connection terminals extending from both ends of the reed switch are bent in the same direction at approximately right angles to pass through both ends of the plate-shaped main body, respectively. The tips protruding from the other side of the plate-shaped main body are soldered to the pair of lead wire terminals housed in the second chamber, so that the opening end of the switch housing tube part of the switch stand lid body is By welding, the reed switch can be accurately positioned inside the switch housing tube via the switch stand, and the inside of the housing tube can be reliably sealed with the lid. Since there is no need to use a reed switch, the workability of installing the reed switch is good. Moreover, the plate-shaped main body of the switch stand is
By fitting the both side edges and the inner circumferential surface of the cylindrical switch accommodation tube part, it is possible to effectively restrict wobbling of the free end of the plate-shaped main body part. Further, the inside of the switch housing tube is divided into first and second chambers each having a substantially semi-cylindrical shape by the plate-shaped main body, and the reed switch is disposed in the first chamber and the lead wire terminal is disposed in the second chamber. Since the housing groove for the reed switch is recessed on one side of the plate-shaped main body, the reed switch can be housed inside the switch housing tube without having to make it very large in diameter.
The switch stand and the lead wire terminal can be accommodated easily, and the solder joint between the reed switch connection terminal and the lead wire terminal is located on the opposite side of the reed switch across the plate-shaped main body. The reed switch can be effectively protected by the plate-shaped main body during soldering work,
Damage to the reed switch due to contact with high-temperature brazing metal can be prevented. Furthermore, the tips of the pair of connection terminals at both ends of the reed switch are bent at approximately right angles in the same direction and pass through both ends of the plate-shaped main body, so that the reed switch itself can be attached to the switch stand by the penetration. It can be easily and accurately positioned, and by simply soldering the ends of both connection terminals to the ends of both lead wires on the other side of the plate-shaped main body while maintaining their penetrating state, the ends of both connection terminals can be easily and accurately positioned. Since separation from both ends of the plate-shaped main body can be reliably prevented, the reed switch can always be correctly positioned and held at a predetermined position on the switch stand, even in the assembled state before the switch stand is set in the switch housing tube. Moreover, since the soldering portion also serves as a holding means for the reed switch with respect to the switch stand, there is no need to provide a special holding means for the reed switch, which contributes to the simplification of the structure.
