But, because above-mentioned slide-mouse must be inserted on the computer with the connector of circuit board upper conductor, so after the slide-mouse installing, all must on reflecting surface, supply its storing by vacating space, and this slide-mouse also regular meeting and can't any storing according to the required of user because of the restriction of lead; Moreover the gauge module in this slide-mouse, it is former also can to roll on reflecting surface for a long time because of trace ball, and the dust lane of reflecting surface is gone in the gauge module, and makes the gauge module produce the situation of loose contact.
So just there is relevant dealer to develop a kind of optical mice, this optical mice is by a drain pan, one loam cake and a circuit board are formed, this circuit board is fixed on the drain pan, centre respectively at circuit board and drain pan is provided with a notch that runs through again, and be provided with a light emitting diode in this circuit board, this light emitting diode bends and the adjacent notches place, and in nuclear circuit board be provided with an inductor, reception place of this inductor is corresponding with notch, in between drain pan and circuit board, be provided with a lens set again, with corresponding to light emitting diode, and, reach reception place of inductor again with the repeatedly refraction path of light source signal via this lens set; Yet, though aforesaid optical mice can effectively solve the shortcoming of traditional slide-mouse, but, because the light source (seeing also Fig. 1) that this light emitting diode sends, weld pad 2 on its wafer 1 is to be located at this wafer 1 top center place, so emitted light source will be because of being subjected to covering of weld pad 2, and form a dark zone in middle position, cause the integrated light source projection uneven, and can be delivered to inductor via each lens and the reflecting surface of this lens set again, so will cause light source projects inequality and loss, so on reality is used, still do not meet the required of user.
Summary of the invention
The purpose of this utility model is to provide a kind of structure-improved of optical mice, by a light emitting diode that can send splendid uniform source of light, with light source signal via lens combination after, see through acceptance division again and transfer to inductor, make have firm combination, group establishes convenient and excellent laser propagation effect, increases practicality.
The utility model is to provide a kind of structure-improved of optical mice, comprises a housing, and this housing is combined by a loam cake and a base, offers a through hole on this base; One circuit board, this circuit board is fixedly arranged in this housing, this circuit board is provided with an inductor, this inductor below neighbour is provided with an acceptance division and a light emitting diode, the wafer top periphery of this light emitting diode is provided with weld pad, and for setting lead, the acceptance division of this inductor and the corresponding setting of through hole on the base; An and lens combination, this lens combination is to be located on the base of this housing, and be to be provided with a reflecting part and lens on this lens combination, this light emitting diode below tiltedly is located in this reflecting part collocation, and this lens correspondence is located at the place, acceptance division below of this inductor, and this lens below is corresponding setting with the through hole of base.
The utility model is to provide a kind of structure-improved of optical mice, and this lens combination is to be provided with one first lens in this light emitting diode below correspondence, and first lens below tiltedly is located in this reflecting part collocation.
The utlity model has firm combination, organize and establish convenient and excellent laser propagation effect.
