Abstract

(57) [Abstract] [Purpose] To obtain a button guide for a push button switch that has a simple resin mold structure, can reduce the mold cost, and can reduce the cost. [Structure] In the button guide member 2, a button guide frame 6, a pair of guide plate pieces 8 and 8 which are vertically provided under the button guide frame, and a mounting plate 7 of a panel 4 are integrally molded by a resin mold. To be done. The guide plate pieces 8 and 8 have a bent portion 10 bent at a substantially right angle at the lower end thereof, and a pair of guide projections 5 and 5 formed on both side surfaces of the button 2 are fitted into the guide plate pieces 8 and 8. Is the bent part 10
Has a guide groove 11 opening on the lower surface. The button 1 has protrusions 5 and 5 between the guide plate pieces 8 and 8 from below as shown by the arrow in the figure.
Is inserted into the guide groove 11 and the guide plate pieces are inserted while widening the gap. The button 1 does not fall out because the projections 5 and 5 hit the bent portions.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a button guide for a push button switch.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 3 and FIG. 4, for example, button guides for push button switches are known. 3 and 4, a is a button, b is a button guide member, c is a switch, and d is a panel to which a push button switch is attached. Wedge-shaped protrusions e are formed on both opposite sides of the button a, and the button guide member b is provided with a button guide frame f and a guide groove g which is vertically provided so as to face the lower edge of the button guide frame f. It is composed of a pair of formed guide plate pieces h and h, and an attachment plate i for attaching the button guide member b to the panel d. As shown by the arrow in FIG. 3, the button a is inserted from below between the pair of guide plate pieces h 1 and h 2, and the protrusions e 1 and e 2 are fitted into the guide grooves g 1 and g 2, respectively. The button guide member b is fixed to the panel d, and the switch c is mounted on the wiring board j and arranged under the button a. In the button guide of this push button switch, when the button a is fitted into the button guide member b, the protrusion e of the button a fits into the guide groove g. Therefore, unless the interval between the lower ends of the guide plate pieces h is widened. The button a does not come off.

[0003]

[Problems to be solved by the device]

 The button guide member b of the conventional push button switch has the above-described shape. Therefore, when this is manufactured using a resin mold, a slide is used for the mold, which complicates the mold and increases the cost. There was an inconvenience. The present invention aims to eliminate such inconveniences of the related art.

[0004]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a button having guide projections formed on opposite side surfaces thereof, a button guide frame, and a downwardly-opposed button guide frame. A button guide member having a pair of guide plate pieces formed with guide grooves into which the guide protrusions are fitted, the pair of guide plate pieces being bent at their lower ends. The guide groove is characterized in that the lower end of the guide groove is opened to the lower surface of the bent portion.

[0005]

[Action]

 The pair of guide plate pieces of the button guide member has, for example, a bent portion bent at substantially right angles at the lower ends thereof, and the guide grooves formed in the pair of guide plate pieces respectively have the lower ends at the above-mentioned bent portions. Since the opening is on the lower surface of the bent portion, there is no need to provide slides on the resin mold, and the protrusions formed on the opposite side surfaces of the button can be folded even if the lower end of the guide groove is open to the lower surface of the bent portion. Since it hits the curved portion, the button does not fall out.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, 1 is a button, 2 is a button guide member, 3 is a switch, and 4 is a panel. The button 1 has wedge-shaped guide projections 5 on opposite side surfaces thereof, and the button guide member 2 is vertically provided so as to face the button guide frame 6, the mounting plate 7, and the button guide frame 6 below. It is composed of a pair of guide plate pieces 8 and 8, which are integrally molded by a resin mold. The switch 3 is mounted on the wiring board 9 and arranged at a position facing the button 1. The above configuration is not different from the conventional one. The pair of guide plate pieces 8 and 8 of the button guide member 2 have bent portions 10 and 10 which are bent at substantially right angles at their lower ends, respectively, and guides to which the guide projections 5 of the button 1 are fitted. The use groove 11 is formed so as to open in the vertical direction and on the lower surface of the bent portion 9.

As shown by the arrow in FIG. 1, the button 1 is such that the guide projections 5 and 5 are fitted into the guide grooves 11 and 11 between the guide plate pieces 7 and 7 from below, and the guide plate piece 8 and When the guide projections 5 and 5 are inserted into the guide grooves 11 and 11 above the bent portion 10 when the guide projections 5 and 5 are inserted while widening the space, the bent portion is not moved even if the guide projections 5 and 5 are moved downward. The button 1 is supported by the button guide member 2 without coming off because it abuts on the button guide member 10. The button guide member 2 is attached to the panel 4 by inserting the button guide frame 6 into the hole 12 of the panel 4 and fixing the attachment plate 7 to the panel 4 with a double-sided tape (not shown).

[0008]

[Effect of device]

 As described above, according to the present invention, the pair of guide plate pieces of the button guide member each have a bent portion at the lower end thereof, and the guide plate piece has a guide groove whose lower end is open to the lower surface of the bent portion. Since the resin mold is formed, the structure of the resin mold can be simplified and the mold cost can be reduced. As a result, the cost of the button guide of the push button switch can be reduced.
