Description

[Detailed Description of the Invention] "Target Technical Field" This invention relates to an illuminated switch, and particularly to an assembly structure of a light emitting element unit.

``Conventional devices and their problems'' Conventionally, in this type of illuminated switch, when assembling the light emitting element unit, the light emitting element, the terminal piece connected to this element, the printed circuit board, etc., were assembled using jigs and tools. However, this process is complicated and requires a lot of time.

``Purpose'' This idea was created in consideration of the drawbacks of the conventional method.
The object is to provide an illuminated switch with good workability.

``Example'' An example of this invention will be described below with reference to the drawings.

That is, a partition wall 2 is provided within the housing 1 at an intermediate portion thereof in the axial direction. The light emitting element unit 3 is accommodated from one end, that is, the upper end opening, and the partition wall 2
is supported by Further, a switch 5 is accommodated in the housing 1 from its lower end. The light emitting element unit 3 includes a printed circuit board 6, a holder 7 mounted on one surface of this board,
It is composed of a light emitting element 8 held by this holder and terminal pieces 9 connected to this light emitting element. The holder 7 and the printed circuit board 6 are provided with through holes 12 and 13 from one surface to the other, through which the lead wires 11 and 11 of the light emitting element 8 pass.

Further, the other surface of the holder 7 is provided with grooves 15, 15 into which the terminal pieces 9 fit, and within the grooves, the holder 7 has at least one pair of Opposed convex portion 1 of
6 and 16 are integrally molded. The terminal pieces 9, 9 are formed in an L-shape, and the corners thereof are grooves 15,
15, and further inside the pair of ends,
One end 17 protrudes to the side of the holder 7 to form a terminal part, and the other end 18 protrudes to the side of the holder 7.
It protrudes from the other side. Furthermore, a notch 19 is formed in one end 17. Further, on the other surface of the holder 7, a pair of engagement protrusions 21, 21 for positioning are provided protrudingly spaced apart from each other at a predetermined interval. The printed circuit board 6 is provided with through holes 25, 25 through which the terminal pieces 9, 9 pass, and engagement recesses 26, 26 that engage with the engagement protrusions 21, 21 for positioning.

Also, inside the housing 1 is a terminal plate 35 for power supply,
35 is housed therein, and is arranged in the axial direction of the housing 1 along the inner wall thereof. Terminal pieces 9 are engaged with one end of these terminal plates.

A plunger 45 for operating the switch 5 is slidably housed in the upper part of the light emitting element unit 3, that is, one end side of the housing 1, and a push button 47 is fitted to one end of the plunger 45 through a collar plate 46. , legs 48, 48 connected to the switch 5 are integrally formed at the other end.

``Effects'' As described above, this invention provides a groove in which the terminal piece fits into the holder, and within this groove, the holder has at least one pair of opposing protrusions that are spaced apart from each other with a smaller distance than the thickness of the terminal piece. Furthermore, the surface of the holder in contact with the printed circuit board is provided with an engagement protrusion for positioning, and the printed circuit board is provided with an engagement recess that engages with the engagement protrusion for positioning. The contact piece can be temporarily assembled to the holder, which has the advantage of greatly improving workability.
