Abstract

The utility model relates to an auxiliary lighting device for a wrist watch, which is used for seeing time clearly in the dark. The auxiliary lighting device for wrist watch uses a button cell as a power supply and is composed of a luminous tube and a button switch, and the luminous tube and the button switch are connected in series. The button cell is positioned in the back cover of the wrist watch. A watch case is used as the positive pole output of the cell. One end of the luminous tube is connected with the watch case, and the other end and an elastic contact sheet of the button switch are linked into integration. A conducting elastic sheet which is linked with the negative electrode of the button cell is fixed out of a machine core in insulation. The timely elastical contact of the fixed point of the conducting elastic sheet and the elastic contact sheet of the button switch is carried out, and the on-off state of a circuit is controlled. The technology makes full use of the available space of the existing watch body to arrange the lighting device. The structure of the utility model is simple. The auxiliary lighting device for a wrist watch is suitable for various mechanical watches and electronic watches. The service life is long, and the trouble that the cell is replaced frequently can be avoided.

Description

The auxiliary lighting apparatus of wrist-watch

The utility model relates to a kind of and wrist-watch or pocket-watch, comprise stem-winder and electronic watch, the auxiliary lighting apparatus of the wrist-watch that organically combines.

Can see clearly the time in the dark in order to make existing wrist-watch, the lighting means that is adopted is very single, promptly scribbling fluorescent powder on the dial plate or on the dial scale or on the pointer, this mode not only has the radioactivity injury to human body, and after the time of using one or two years, the light-emitting phosphor amount will reduce greatly, and it is very difficult to want the time of seeing clearly, even can't see clearly, " bright table at night " will have a false reputation.

It is light source with the electronic light-emitting component that goal of the invention of the present utility model is to provide a kind of, can organically combine, form simple, long-lived wrist-watch auxiliary lighting apparatus with the wrist-watch inner structure.

Realize the wrist-watch auxiliary lighting apparatus of foregoing invention purpose, the technical characterstic of its technical scheme is: its lighting circuit is composed in series by twist button battery, luminotron and button type switch; Twist button battery is located in the bonnet of table, and promptly watchcase is its anodal output; Movement is outer, an end and watchcase insulate is fixed with at least one and is used for the conductor shell fragment that links with the twist button battery negative pole; The elastic contact chip that the spring catch bar insulation promotion one and luminotron one end of button type switch links contacts formation one shell fragment touch switch with the point of fixity of conductor shell fragment in good time, and the luminotron other end and watchcase link.

The wrist-watch auxiliary lighting apparatus that the utility model is designed, made full use of in existing wrist-watch or pocket-watch or the similar table body, between movement and the bonnet, between movement and the watchcase, existing space, dial plate top is provided with this lighting circuit, therefore the physical dimension of table can not change.Because volume and the minimum luminotron of power consumption, just can satisfy the brightness of illumination requirement of stopwatch as light emitting diode, so decoration design that the surface that can not influence stopwatch on the one hand is set of light emitting diode, particularly this auxiliary lighting apparatus has adopted special-purpose supplying cell, thereby electronic watch and stem-winder all can be installed this auxiliary lighting apparatus, and because this battery is separately set in the watch back cover place, or make the integrative-structure of the battery that has watch back cover, created condition for adopting jumbo twist button battery, the service time of this lighting device can be considerably beyond the electricity consumption time of electronic watch operation itself, thereby avoided the trouble of frequent replacing battery.Technology of the present utility model is simple, is easy to industrial implementation application and maintenance.

Describe technology contents of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 3 is for being installed in twist button battery 1 side sectional view of the bonnet 4 of table

Fig. 4 is for being installed in twist button battery 1 front schematic view of the bonnet 4 of table.

As shown in the figure, the lighting circuit of auxiliary lighting apparatus of the present utility model is to be power supply with twist button battery 1, is composed in series by light emitting diode 2 and button type switch 3.The luminous point of light emitting diode 2 is positioned at the top of dial plate, for not influencing the whole structure of dial plate, light emitting diode 2 is preferably disposed in dial plate and the table sidewall between covering or table covers among the edge trim shade, light emitting diode 2 one ends and watchcase link, and the elastic contact chip 8 of the other end and button type switch 3 links.For making light shine on the surface all sidedly, preferably adopt two or more light emitting diodes in parallel 2 evenly to be distributed on the dial plate side, one end of these light emitting diodes 2 all is communicated with on watchcase, and the other end all is connected in parallel on the elastic contact chip 8 of button type switch 3.Twist button battery 1 is fixedly mounted in the bonnet 4 of table, can a circular recess be set on the bonnet 4, twist button battery 1 is located in this circular recess, or the integrative-structure that adopts twist button battery and watch back cover to make, the positive pole that is twist button battery is exactly a bonnet of showing body, and watch back cover 4 is the cathode output end that watchcase then becomes twist button battery 1.For the conductor shell fragment 5 link to each other with twist button battery 1 negative pole is set, an end of conductor shell fragment 5 is fixed on the plastic frame of movement 9 outer rims, other end perk is used for linking to each other with the negative pole of twist button battery behind fastening watch back cover 4; For the center is symmetrical arranged conductor shell fragment 5, outside plastic frame, be provided with the symmetrically arranged conductor shell fragment 5 in a metal lining ring 6, two centers and be fixedly connected with metal lining ring 6, become an interface that links with battery cathode of circuit; As shown in the figure, this conductor shell fragment 5 also can be made into two ends and metal lining ring 6 is fixedly connected, and the center is the shell fragment of the one of elasticity perk.Present embodiment, button type switch 3 is positioned at the side of table, this switch can select for use " two lion " table calendar of selling as part in the market to adjust knob, utilize its catch bar insulation to promote elastic contact chip 8, be communicated with contact point 7 with conductor shell fragment 6 in good time, constitute the shell fragment touch switch as battery cathode.For realizing the insulation of elastic contact chip 8 and catch bar, a side that contacts with catch bar at elastic contact chip 8 scribbles one deck insulating gel.When pressing the catch bar of button type switch 3, its elastic contact chip 8 is communicated with contact point 7, conducting illumination series circuit then, and light emitting diode 2 is luminous, illuminates dial plate; When loosening catch bar, elastic contact chip 8 is separated with contact point 7 under the elastic reaction of himself, and the series circuit that then throws light on is cut off, and light emitting diode 2 quits work.
