Description

[Detailed Description of the Invention] This invention relates to an indicator light that allows accurate positioning of a lamp unit.

In conventional various indicator lights, the mounting means for the lamp part is screw type, so the tightening position of the lamp part is not constant, which makes it difficult to position when engraving letters etc. on the front of the lamp part. Met.

In addition, if the characters engraved on the surface of the lamp unit are bent and the lamp unit is installed, adjusting the position of the holder to position the characters straight will cause the connection terminal to be installed at the rear of the holder to be bent. There was a drawback.

In addition, the lamp unit must be rotated to attach it to the holder, which has the disadvantage that it takes time and effort to attach it.

In order to eliminate these conventional drawbacks, the present invention facilitates the stationary positioning of the lamp unit by attaching it to the holder in a fitting manner.

An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes a lamp unit made of translucent synthetic resin, which has a display section 2 on which characters are engraved on the front surface, and a cylindrical body 3 connected to this display section. A pair of flexible locking pieces 4, 4 are provided at the rear of the locking pieces 4, 4, and retaining protrusions 5.5 are formed on the outer surfaces of the tips of the locking pieces, respectively. Small holes 6, 6 are formed.

Reference numeral 11 denotes a holder to which the lamp unit 1 is attached, and an outer cylinder 12 with a bottom.
A large-diameter engaging portion 13 is provided concentrically on the outer periphery of the distal end thereof, and a thread 14 is formed on the outer cylinder 12 behind this engaging portion 13.

Engagement holes 15, 15, into which the engagement protrusions 5, 5 engage, are formed on the inner surface of the approximately middle portion of this outer cylinder, and a pair of outwardly opening tapered holes are formed from the engagement holes 15, 15 toward the front of the holder. A guide groove 16.16 is formed.

Reference numeral 21 is an LED indicator light, which has a hat 22 with a diameter that can be accommodated in the cylindrical body 3 of the lamp unit, and a plurality of L on the front of this body.
Attach the ED23゜23 and attach the cylindrical body 3 to the outer wall of the body.
The LED indicator light 21 is integrally and removably attached to the light cover part 1 by forming protrusions 24 and 24 that fit into the small holes 6, 6 provided in the light cover part 1.

Reference numeral 25 denotes a reflective section provided on the front side of the LED indicator light.

26 indicates one lead leg 2 of the LED 23.
7.27 is attached to the lower end of the rear body part 22a provided at the lower part of the body part 22, and the other ends of the other lead legs are bent and connected to the rear body part 22a. A protruding portion 28.28 is provided to protrude outward from approximately the middle portion.

Reference numeral 30.30 denotes a contact spring whose lower end is exposed at the lower end of the outer cylinder 12, and the contact springs 30, 30 are fixed to the lower part of the outer cylinder. 2
8.28.

35 is a rear holder attached to the lower part of this outer cylinder 12;
A terminal piece 3 that accommodates a resistor 36 inside and connects to this resistor
7.37 is disposed in a connecting tube 38 provided at the upper part of the holder, and when this connecting tube 38 is attached to the outer tube 12, the contact spring 30.30 and this terminal piece 37.37 are connected. A resistor 36 is connected to the LED.

According to the present invention, the holder 11 is inserted into the mounting hole 31 provided in the panel 40, and the nut 17 is screwed into the thread 14 to fix the holder 11 to the panel 30.

In this case, as shown in FIG. 1, if the engagement holes 15, 15 and the series of guide grooves 16, 16 are positioned horizontally or vertically and the holder is attached and fixed to the panel, the light cover can be engaged. By positioning the mating projections 5, 5 horizontally or vertically and engraving characters, etc. on the display part 2, the lamp cover part 1 can be attached to the holder 11 without bending the characters.

Furthermore, since the LED indicator light 21 is held inside the light cover section 1, if the LED indicator light breaks down, the LED indicator light can also be taken out by removing the light cover section 1 from the front of the panel 30. and can be easily replaced with a new one.

In addition, since the lamp cover part 1 is stationary at a fixed position in the holder 11, the protrusion part 28, 28 of the LED 23 which is mounted inside the lamp cover part 1 and the contact spring 30 which is mounted inside the rear part of the holder 11 are attached. , 30 can be smoothly contacted.

As described above, the present invention provides tapered guide grooves 16, 16 on the inner surface of the holder 11, and if the lamp cover part 1 is pushed in without engaging the engaging protrusions 5, 5 with the guide grooves, the lamp cover The engaging protrusions 5, 5 of the parts can easily engage the engaging holes 15, 15,
Since the position of the display section 2 on which characters and the like are engraved does not change, positioning is easy and accurate, which is a useful feature.

In addition, to remove the light cover part 1 from the holder 11, hold the light cover part and pull it a little forcefully. , LEDs can be easily replaced.
