Abstract
The utility model relates to a kind of ship shape key light guide plate structure, comprise light guide panel, ship shape button, pcb board, touch-switch, LED light source, described ship shape button be installed on described light guide panel by keyway, and exceed the front of described light guide panel, the reverse side of described ship shape button has 2 short guiding columns, be pressed on 2 touch-switch respectively, described touch-switch and described LED light source to be welded on described pcb board and to be electrically connected, and described pcb board is arranged on the back side of described light guide panel.The utility model has the advantage of the mode adopting the mode of welding touch-switch to replace conventional package reed, while simplification ship shape key light guide plate structure, improve reliability and the maintainability of product.
Description
Technical field
The utility model relates to a kind of ship shape key light guide plate structure.
Background technology
Traditional ship shape key light guide plate structure as shown in Figure 1, comprises light guide panel 11, ship shape button 12, pcb board 13, reed 14, LED light source 15, light conductor 16, one side glue 17, double faced adhesive tape 18.Wherein, the guide pillar of ship shape button through the guide pillar hole on light conductor, and withstands on reed; And reed adopts double faced adhesive tape and one side rubber seal dress to be limited on the corresponding conducting contact of pcb board; LED light source is welded on pcb board, for illuminating the character on ship shape button.On traditional structure, the encapsulation operation of reed and detachable maintaining are all inconvenient; And the component of horizontal direction can be produced due to ship shape button in pressing process, and act on reed by guide pillar, make reed easily produce displacement after long-term work, thus affect the conducting reliability of ship shape button.
Summary of the invention
The purpose of this utility model is the structure simplifying traditional ship shape keystroke light conducting plate, solves the problems referred to above existing when reed encapsulates, provides a kind of ship shape key light guide plate structure.
For achieving the above object, the technical solution of the utility model is: a kind of ship shape key light guide plate structure, comprise light guide panel, ship shape button, pcb board, touch-switch, LED light source, it is characterized in that: ship shape button be installed in described light guide panel by keyway, and exceed the front of described light guide panel, the reverse side of ship shape button has 2 short guiding columns, be pressed on 2 touch-switch respectively, touch-switch and LED light source to be welded on pcb board and to be electrically connected, and pcb board is arranged on the back side of described light guide panel.The material of described light guide panel is aluminium alloy or aerial organic glass.The material of described ship shape button is aerial organic glass.Described short guiding column is cylindrical boss structure.Described touch-switch top is equipped with one can the column silica gel head of knee-action.The end face of described column silica gel head, center line overlap with the end face of described short guiding column, center line respectively.The utility model has the advantage of the mode adopting the mode of welding touch-switch to replace conventional package reed, while simplification ship shape key light guide plate structure, improve reliability and the maintainability of product.
Accompanying drawing explanation
Fig. 1 is traditional ship shape keystroke light conducting plate structural representation.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to drawings and Examples, the utility model is described in further detail.
In fig. 2, ship shape key light guide plate structure comprises light guide panel 1, ship shape button 2, pcb board 3, touch-switch 4, LED light source 5.Ship shape button 2 be installed on light guide panel 1 by keyway, and exceed the front of described light guide panel 1, the reverse side of ship shape button 2 has 2 short guiding columns, be pressed on 2 touch-switch 4 respectively, touch-switch 4 and LED light source 5 to be welded on pcb board 3 and to be electrically connected, and pcb board 3 is arranged on the back side of light guide panel 1.
The material of described light guide panel 1 is aluminium alloy or aerial organic glass, the material of described ship shape button 2 is aerial organic glass, described short guiding column is cylindrical boss structure, described touch-switch 3 top is equipped with one can the column silica gel head of knee-action, and the end face of column silica gel head, center line overlap with the end face of described short guiding column, center line respectively.
In the present embodiment, each ship shape button has 2 touch-switch for 2 times, control the break-make of 2 road signals respectively, press any one end in ship shape button 2 two ends, the short guiding column of this end reverse side acts on the column silica gel head of corresponding touch-switch 3, and make it action, trigger a corresponding road signal circuit conducting, simultaneously another road signal circuit not conducting of ship shape button 2.In addition, described ship shape button 2 is carved with the character needing printing opacity, when pcb board 3 connects mains lighting supply, on it, the LED light source 5 of welding can send visible ray, thus illuminates the character on ship shape button 2.
Because touch-switch 5 is directly welded on the relevant position on pcb board 3, the encapsulation without the need to double faced adhesive tape and one side glue is spacing, and structure is simple, firm welding, and can not be shifted, reliability is higher; Every touch-switch, as a separate unit, improves the degree of modularity of product, and can not cause association impact, and maintain and replace is more convenient.
Below only have expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (6)
