Power saving switch structure of electronic device

The present invention relates to a power saving switch configuration as a power switch in an electronic device.

The application of wireless optical mice is now quite extensive, such as current home computers, personal mobile devices, school teaching equipment, corporate conference rooms, etc. The past roller-type wired mouse has been almost eliminated due to wireless optical mouse The effect is to replace the cable with wireless, and replace the roller with optical, which greatly enhances the convenience of carrying, using and the sensitivity of operation.

Referring to FIG. 7, a bottom of a known wireless optical mouse is disclosed, which includes a bottom case 60 and a substrate 64 disposed inside the bottom case 60. A bottom of the bottom case 60 is provided with a lens assembly 61 and forms a a switch slot 62; a battery slot 65, a sensor 66, and a switch body 67 are disposed on the substrate 64 of the bottom case 60. The lens assembly 61 is configured to capture an image reflected by the optical mouse moving on the desktop. And translating the image signal to the information such as the moving coordinate through the sensor 66; the switch slot 62 is hollow and has a paddle 63, and the paddle 63 is dialed to control the switch body 67 on the substrate 64; The switch body 67 is used to control whether the positive and negative electrodes of the battery slot 65 are turned on; as shown in FIG. 8, the switch body 67 provided on the substrate 64 includes a plurality of pins 69 and a push extending from the side. The button 68 is soldered to the substrate 64, and the push button 68 is connected to the paddle 63. When the user pushes the paddle 63, the pin 69 is switched to work. For example, push up to ON (ON) means switching to the on position of the foot 69 The mouse works fine.

It can be known from the above-mentioned known wireless optical mouse that when the user no longer needs to use, the paddle 63 will be pushed to the OFF position, and the linked push button 68 will also switch the switch. The body 67 switches to a non-conducting pin to switch the power of the wireless optical mouse in this way, but the above-mentioned switch body 67 mostly uses a DIP switch, which is very small and has a small foot. Bit 69 is very close, and the DIP switch is very inexpensive. When it is manufactured in large quantities, the quality of its manufacture is quite rough. The distance between the poles and poles of most pins 69 is very close, and impedance is generated even in the OFF state. The flow of a small current, or the frequent penetration of solder oil into the switch, causes the switch to be in the OFF state but still consumes power; therefore, it is necessary to propose a better solution for the above situation. .

After the battery is installed in the battery compartment of the housing and is respectively in contact with the first and second contact electrodes in the above-described power-saving switch configuration, when the push button is moved from the first position to the second position in the positioning member, the push button will be pressed. The free end of the electrical connector makes contact with the second power contact to turn on the power circuit; when the use is completed and the power is to be turned off, the push button is pushed back from the second position to the first position, and the push button will be The free end of the electrical connector is separated from the second power contact and an air gap is formed, thereby completely opening the battery with the first and second power contacts, so as to effectively solve the problem that the conventional power switch still has a slight current through formation loss and battery Always turn on and cause water problems.

Regarding the power-saving switch structure of the electronic device of the present invention, the electronic device includes, but is not limited to, a wireless mouse, a wireless keyboard, and the like, and an electronic device having a battery and having a power switch, and in the preferred embodiment, is wireless.

In this embodiment, the housing 21 forms a slot at the bottom of the corresponding positioning member 24. And the positioning member 24 forms an adjacent first positioning recess 24A and a second positioning recess 24B on one side; the push button 22 is formed on one side and the bottom to form an elastic convex portion 22C and a push button 22D, respectively. The elastic protrusion 22C corresponds to the first and second positioning recesses 24A, 24B of the positioning member 24, and the push button 22D is pierced by the slot at the bottom of the housing 21. The opening/closing action in the above configuration is as follows When the battery 40 is placed in the battery compartment of the casing 21, the negative electrode and the positive electrode of the battery 40 will be in contact with the conductive coils of the first and second contact electrodes 28, 29, respectively, and the elastic convex portion 22C of the push button 22 corresponds to In the position of the second positioning recess 24B, it represents that the push button 22 is in the second position (for example, ON), and the jacking portion 22A on the push button 22 will press the connecting portion of the electrical connector 30 with the pressing portion 22B thereof. 301, making contact with the second power contact 26 to turn on the power circuit to form an open state; When the power is turned off and the power is turned off, the push button 22 is pushed back from the second position to the first position (for example, OFF).
