Description

Technical Field

[0001] The present invention relates to a CMOS battery adapter device used in a retail self-service equipment mainboard. The device can be conveniently installed in a CMOS battery holder of a retail self-service equipment mainboard of various shapes and sizes to achieve a change in the CMOS battery capacity of the retail self-service equipment mainboard. By connecting a large-capacity battery through the device, the frequency of replacing the mainboard CMOS battery is effectively reduced, thereby reducing operating costs. At the same time, different CMOS battery capacities can be adapted to different types of projects, and batteries of appropriate capacities can be selected, so that the project can effectively reduce costs and increase efficiency when a large number of mainboards are used. Background Art

[0002] Retail self-service equipment is a new type of high-tech equipment that closely links information technology with various production and service scenarios, such as retail POS integrated cash registers, retail self-service cash registers, ticket vending machines, medical self-service printing terminals, self-service government affairs terminals, etc., which have been widely used in various industries. Summary of the invention

[0003] The present invention is a CMOS battery transfer device used in a retail self-service device motherboard. The device can be conveniently installed in a CMOS battery holder of a retail self-service device motherboard of various dimensions to change the CMOS battery capacity of the retail self-service device motherboard. The device can be connected to CMOS battery capacities of various specifications. The device has a 1-way 2PIN CMOS battery socket and a 1-way speaker. The device can adapt to different CMOS battery holders in a layered nesting manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0004] Attached Figure 1 It is a top view of the device of the present invention The meaning of the numbers in the figure: 1. Inner adapter positive contact 2. Outer adapter positive contact 3. CMOS battery socket 4. Speaker Attached Figure 2 It is a side view of the device of the present invention The meaning of the numbers in the figure: 2, positive contact of the outer adapter 3, CMOS battery socket 4, speaker 5, negative contact surface Implementation

[0005] The device of the present invention is essentially a PCBA that can be directly snap-mounted on the CMOS battery holder of a retail self-service motherboard.

[0006] The bottom of the device of the present invention is 5 negative contact surfaces, and the innermost compatible battery specification is CR1220, and the radius can be expanded by nesting layers. The innermost 1 positive contact point of the device of the present invention is insulated below, and the side can be in direct contact with the copper sheet of the outer nested board card to ensure normal conduction of the circuit. The 2 positive contact points of the nested board are insulated below. The innermost top of the device of the present invention has 3-way 2PIN CMOS battery sockets, which is convenient for external CMOS batteries of various specifications and models. The innermost top of the device of the present invention has 4-way speakers, which are turned on by electrical signals. When the battery voltage is lower than a certain value (the design value of this device is 2.8V, and this value can be modified according to the actual project needs to meet the needs of the circuit modification), the speaker buzzes.
