Description

[Detailed description of the invention] This invention relates to a solenoid that has a built-in lamp for indicating power supply or energization in the housing, and allows various parts to be easily assembled to the housing while reducing the amount of labor involved. It is an object of the present invention to provide a solenoid for a solenoid valve with a lamp that can be reduced in number.

The drawings showing the embodiments of the present application will be described below.

In the solenoid A, 1 is a housing, 2 is a bottom plate facing the opening 1a of the housing 1 and attached detachably, 3 is a gasket, 4 is a fixed core, 5 is a coil, 6 is a lead wire, and 7 is a movable The iron core and 8 indicate the bush pins, respectively.

Next, the lamp portion provided near the opening 1a of the housing 1 will be explained.

Reference numeral 9 denotes a lamp holder, which is made of a transparent material such as resin or glass fiber.

In this lamp holder 9, reference numeral 10 denotes a display window, which is formed thin to allow light to pass through easily, as clearly shown in FIG.

Note that the lamp holder 9 may be formed of a non-transparent material, and only the display window portion 10 may be formed of a translucent material, or may be formed thin so as to be translucent.

11 is a printed board, and 12 is a lamp, in which a current-carrying light conversion element such as a neon bulb, filament bulb, or light emitting diode is used.

13 is a protective resistor for the lamp 12, and the lamp 12 and the resistor 13 are connected to the copper foil 11a of the printed board 11.
It comprises a circuit for causing the lamp 12 to emit light.

Note that this copper foil 11a also constitutes a power receiving element for receiving current supply from a power feeding element to be described later.

14 is a filling that fixes the printed board 11, lamp 12, etc., and prevents oil from entering by eliminating the space between the display window 10 and the lamp 12, thereby preventing poor light transmission. This is to prevent it.

Note that 15 is a gasket inserted between the housing 1 and the lamp holder 9 so that there is no gap.

Next, 16 is a plug holder, 17 is a plug holder 16
The plug pin 18 and 19 are a connection piece and a connection spring which are illustrated as power supply elements, and the connection piece 18 is connected to the lead wire 6.
The connecting spring 19 is also connected to the head 17a of the plug pin 17 by a joining means such as brazing or welding, while the connecting spring 19 is always in contact with both the copper foil 11a of the printed board 11 and the connecting piece 18.

Note that 16a is a holding hole for the connection spring 19 drilled in the plug holder 16, and lb and IC are support pieces formed integrally with the housing 1 and provided to support the plug holder 16.

Next, in the valve B, 20 is a valve body, 21 is a valve pin, and 22 is a receptacle housing, which is made of an insulating material such as synthetic resin.

23 is a receptacle contact, and 24 is a terminal screw, which is provided so that a conducting wire can be connected to the contact 23.

25 is a conductor introduction hole bored in the body 20, 26 is a lid, and 27 is a fastener for fixing solenoid A to valve B.

Next, the assembly of the solenoid A having the above structure will be explained.

First, a printed board 1 with a lamp 12 and a resistor 13 attached.
1 is fixed to a lamp holder 9 with a filler 14, and the lamp holder 9 is further attached to the housing 1 via a packing 15.

Next, assemble the electromagnet with the fixed core 4, coil 5, movable core 7, etc., install it in the housing 1, fit the connection spring 19 into the holding hole 16a of the plug holder 16, and then attach the plug holder 16. Support piece lb, I
Place it on C and cover it with the bottom plate 2 to complete the assembly.

In the solenoid A assembled in this way, the lamp holder 9 and the plug holder 16 are formed separately, so when attaching the solenoid A to the valve B, it is necessary to The force applied to
The support piece 1b is supported by the IC and is not transmitted to the plug holder 9. On the other hand, since there is a gap between the mounting hole 2a and the insertion part 16b of the plug holder 16 in the direction perpendicular to the axis, the plug is not transmitted to the plug holder 9. The holder 16 is positioned in the most suitable position by the receptacle.

As described above, in this invention, the plug holder 16 that holds the plug pin 17 connected to the electromagnet is formed separately from the lamp holder 9, so when the electromagnet and the lamp holder 9 are assembled into the housing 1, the plug holder 16 is formed separately from the lamp holder 9. It has the advantage that it can be assembled independently and the work can be done very easily.

Moreover, even if the plug holder 16 and the lamp holder 9 are formed separately as described above, when the plug holder 16 is attached to the bottom plate 2, the power supply element 18.
9 and the power receiving element 11a are in contact with each other, when the plug holder 16 is attached, the electrical connection from the plug pin 17 to the lamp 12 can be made at the same time, reducing the amount of effort required for assembly. There are also some benefits.
