Be equipped with rotary or touch operation knob in the operation panel, the operation of knob is conveyed to the printed circuit board (PCB) that front end casing inboard is adhered to, and operates in the switch element that forms on the printed circuit board (PCB), thereby electronic products is controlled.
Same as shown in Figure 1, printed circuit board assembling structure was by constituting with lower device in the past: the operation knob 21 that has contact point 21a; On one side, be formed with operation knob with forming a plurality of fixing front end casings 10 around installing port 11 and the installing port with projection 13; Have and insert casing fixing fixing hole 23 and the knob support framework 20 that is connected a plurality of elastic limit devices 25 of supporting knob with projection; And the fixing hole of supporting the framework inboard to have to insert the casing fixed projection at knob 33 and according to the printed circuit board (PCB) 30 of the contact-making switch of knob-operated.Printed circuit board (PCB) 30 is fixed with outstanding front end casing 10 by fixing hole 33 and is carried out thermal welding (thermal welding part: P), fix front end casing 10 with projection.
But identical therewith printed circuit board assembling structure in the past is when final assembling, part for the narrow and small assembling of casing should be carried out thermal welding, so want to carry out accurately relatively difficulty of assembly operation, and since the bad operation of thermal welding can cause assembling unfavorable, when maintenance, only carry out enforceable separation, relatively more difficult concerning maintenance like this, nor economical.
Summary of the invention
The present invention is an existing problem above solving, and the simple structure that provides a kind of printed circuit board (PCB) that use in the electronic products operation control is installed to separate.
For achieving the above object, of the present inventionly utilize control that operation knob (knob) operates to comprise as lower device: in one side with the package assembly of printed circuit board (PCB), front end casing (frontcabinet), the a plurality of fixing projection of using that it is equipped with the operation knob installing port and forms around the installing port, and the fixing boss of usefulness (boss) in two ends; Be equipped with and insert the fixing fixing hole with projection of casing is connected a plurality of elastic limit devices (stopper) of knob with support knob support framework (frame); The printed circuit board (PCB) of fixing hole that inserts the casing fixed projection and the switch that moves according to the operation knob operation is equipped with in knob support framework inboard; There is screw to insert mouthful at two ends, and by the fixing fixing boss of using of front end casing, and then printed circuit board (PCB) separated or the analog bracket (Bracket) of combination with the front end casing.
If according to enforcement example of the present invention, above said analog bracket be characterized in, the tension force bend is equipped with for stably supporting printed substrate.
According to enforcement example of the present invention, above its characteristics of said switch be touch switch (tactswitch).
As according to enforcement example of the present invention, above its characteristics of said analog bracket be that according to the operation of operation knob, for the switch that makes knob and printed circuit board (PCB) stably contacts, the part of contact printed circuit holding is provided with a plurality of support projections.
According to the invention process example, above form the recess of promising configuration signal cable on the said analog bracket.
Identical with the above, the invention provides the simple structure that a kind of printed circuit board (PCB) that use in the electronic products operation control is installed can separate.

Embodiment
Following with reference to institute's accompanying drawing, the desirable example of implementing of the present invention is described in detail.
Fig. 2 is according to the view after decomposing schematic representation and the assembling before the assembling of printed circuit board (PCB) assembling formation of the present invention; In the printed circuit board (PCB) assembling as shown in the figure, for representing with identical symbol with the identical or similar part of the printed circuit board assembling structure of foundation conventional art.
As reference Fig. 2 is words, and the aspect that printed circuit board assembling structure of the present invention is big mainly comprises: front end casing 10; Operation knob framework 20; Printed circuit board (PCB) 30, analog bracket 40.
Dispose knob in the inboard of front end casing 10 and support framework 20, it has inserts casing fixing fixing hole 23 and a plurality of elastic limit devices 25 that contact support knob 21 with projection 13.
Above said elastic limit device 25 be through certain intervals and the vertical topography set, more satisfactory is to be made of plastics, the operation knob rotation or the bounce of press operation down are provided, under operation knob during press operation, and support that operation knob together makes it restore to original position.
Support the inboard of framework 20 to be equipped with printed circuit board (PCB) 30 at knob, printed circuit board (PCB) comprises fixing hole 33 that inserts the casing fixed projection and the switch that operates according to knob.
Above the switch of said printed circuit board (PCB) can be the contact-making switch that miniaturized electric handset device mainly is suitable for, this contact switch contacts the formation control circuit in the operation knob rotation or when pressing down with the contact point 21a of knob.
Above a side of said printed substrate 30 dispose the analog bracket 40 that plate is fixed on casing 10.
With identical shown in Fig. 3 a and Fig. 3 b, above said analog bracket 40 are the parts that are formed with certain-length on the longitudinal direction, for fixing front end casing is provided with screw patchhole 41, its effect is to insert on the two ends the fixedly screw of the boss of front end casing 10.Above said screw patchhole 41 around be formed with the guiding wall (wall) that is used for leadscrew.
