One end of the rod-shaped part A protrudes from the front surface of the housing in the previous period, and the other end is located in the vicinity of the switch 7 and in the groove 1. The switch is reliably operated by coupling the spring part integrally formed with the holding component B so as to be elastically deformable.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a push button device for operating a user control switch or the like incorporated in the front surface of an electronic device such as a color television receiver.

[0002]

[Prior Art]

 An operating push button device incorporated in the front surface of a conventional color television receiver or the like has a structure shown in FIGS. 4 and 5.

The push button 8 is generally integrally formed of a thermoplastic resin having high elasticity such as ABS, and is generally attached to a boss 9 provided on the housing. A part of the part connecting the attachment part of the button and the operation part 11 is thinned to have a hinge effect, and when the operation part is pushed from the front side, it is deformed by the hinge part 10, and the electronic circuit printed board 6 inside It has a structure for operating the switch 7 provided in.

[0004]

[Problems to be solved by the device]

 When the resin-made hinge type push button device is used as in the conventional example, the operating portion 11 and the switch contact portion 12 move in an arc shape with the hinge portion as a fulcrum to operate the push switch 7. Therefore, this method is possible only when the distance L from the front surface of the housing to the switch is small.

The present invention provides a resin button device that can be used when the distance L from the front surface of the housing to the switch is large.

[0006]

[Means for Solving the Problems]

 The present invention is an apparatus composed of two main components, a resin rod-shaped part A that constitutes an operating part and an operating part, and a holding part B that holds the bar-shaped part A and that constitutes the elastic spring part 2. Is.

There are a plurality of resin rod-shaped parts A depending on the number of switches of the equipment used.

[0008]

[Action]

 Even when the distance L from the front surface of the device housing to the push switch mounted on the printed circuit board is large, the push switch can be reliably operated.

[0009]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a main part of a push button device according to an embodiment of the present invention, and FIG. 2 is a sectional view of the push button device mounted on a device as seen from the cutting lines S1 to S1.

The rod-shaped part A includes an operation part A1 for pushing with a finger from the front surface of the housing 20, and an operation part A2 for pushing the push switch 7, and is fitted with the resin spring part 2 provided in the holding part B. A spring fitting groove 1 is provided. The holding component B has a spring portion that holds the rod-shaped component A slidably in the axial direction and that regulates the longitudinal movement of the rod-shaped component A (that is, the stroke movement in the axial direction). It is a resin integrally molded part. The spring portion 2 is formed by connecting thin semicircular shapes in a predetermined manner, and elastically deforms to function as a spring. As described above, it fits in the groove 1 of the rod-shaped component A and serves to control the longitudinal movement of the rod-shaped component A. Further, the holding component B has semi-circular recessed portions B1 for supporting the rod-shaped component A on its end surface at predetermined intervals, and the hinge 3 is bent about the symmetrical axis to slide the rod-shaped component A in the axial direction. It is configured to hold as much as possible. The holding part B, which is folded into a box shape, has a structure in which the respective system stop claws 4A and 4B are fitted to each other and do not open due to the elastic force of the resin. Further, the plurality of mounting holes 5 are provided for the purpose of fitting into the bosses 9 arranged in the housing 20 and fastening or fixing by welding.

FIG. 2 shows a state in which the button of the present invention is mounted on the housing 20 of the device. When the rod-shaped component A is pushed from the front surface of the housing 20, the rod-shaped component A resists the push switch 7 provided on the internal electronic circuit printed circuit board 6 against the spring portion 2 (that is, while elastically deforming the spring portion 2). Move it and make it work). When the finger is released, the bar-shaped component A returns to its original position due to the coercive force of the push switch 7 and the elasticity of the spring portion 2.

[0013]

[Effect of the device]

 As described in the above embodiment, by using the push button device of the present invention, stable and reliable switching operation can be obtained even when the distance L from the front surface of the housing to the push switch is large.

Further, since the position of the push switch on the printed circuit board can be freely selected, there is no need to be restricted by the structure or the external design unlike the conventional example. Also, the B part of the push button device is highly common, and by changing the length and shape of only the A part, there is an advantage that it can be applied to various sizes and design models.
