[0002] PC-grade dual-power automatic transfer switch is a power management device mainly used in computer systems and other electronic devices. Its main function is to achieve seamless switching between two power sources, so that when one power source fails, the system can automatically switch to the backup power source, thereby ensuring the continuous operation of the equipment.

[0003] In existing technologies, PC-level dual-power automatic transfer switches require internal sensing electronic components to detect the circuit status and enable seamless switching between the two power sources. However, these sensing electronic components are delicate and susceptible to damage from impacts when installed inside the PC-level dual-power automatic transfer switch, compromising accuracy and increasing both usability and cost. Therefore, this invention designs a low-cost PC-level dual-power automatic transfer switch. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing PC-level dual power automatic transfer switch, it is necessary to add an internal sensing electronic component to detect the circuit status so as to achieve seamless switching between the two power sources. However, the sensing electronic component is relatively delicate, and if it is placed inside the PC-level dual power automatic transfer switch, it will be damaged by impact, which makes it difficult to guarantee high accuracy during use. This not only affects the use of the PC-level dual power automatic transfer switch, but also increases the cost of using the PC-level dual power automatic transfer switch. Therefore, a low-cost PC-level dual power automatic transfer switch is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-cost PC-grade dual-power automatic transfer switch includes a switch housing. Multiple interfaces are provided on the upper and lower inner walls of the switch housing. Multiple terminals are slidably arranged on the inner walls of the switch housing. The tops of the terminals are in contact with the upper interfaces. A wire is electrically connected to the bottom of each terminal. A connecting end cap is electrically connected to the side of the lower interface opposite to the wire. An electric push rod is fixedly connected to the top inner wall of the switch housing. A push block is fixedly connected to the piston rod end of the electric push rod. A transmission rod is hinged to the side wall of the push block. The end of the transmission rod facing away from the push block is hinged to the side wall of one of the terminals.

[0007] Preferably, guide blocks are fixed on the side walls of the plurality of terminals, and guide grooves are provided on the inner wall of the switch housing. The guide blocks are slidably disposed on the inner wall of the guide grooves, and connecting rods are fixedly connected to the corresponding sides of the two terminals.

[0008] Preferably, a top rod is fixedly connected to the side wall of each of the plurality of terminals, and an insulating pressure plate is fixedly connected to the end of the top rod away from the terminal, and the insulating pressure plate is pressed tightly at the bottom of the interface above.

[0009] Preferably, a housing is fixedly connected to the bottom inner wall of the switch housing, a controller is fixedly connected to the bottom inner wall of the housing, a first wire is electrically connected to the side wall of the connecting end cover, an electromagnet is fixedly connected to the inner wall of the housing, the electromagnet is electrically connected to the first wire, an adapter is fixedly connected to the top inner wall of the controller, a second wire is electrically connected to the side wall of the electric push rod, one end of the second wire away from the electric push rod extends to the upper surface of the adapter, and the terminal of the controller extends to the upper surface of the adapter.

[0010] Preferably, a magnetic ring is provided above the electromagnet, and the sidewall of the magnetic ring is slidably disposed on the inner wall of the box.

[0011] Preferably, the inner wall of the magnetic ring is fixedly connected to an adapter block, the adapter block has an adapter wire inside, and the bottom of the adapter block is located above the adapter seat.

[0012] Compared with the prior art, this utility model provides a low-cost PC-grade dual power automatic transfer switch, which has the following advantages:

[0013] 1. This low-cost PC-grade dual-power automatic transfer switch, when the circuit power is cut off, the first wire cannot energize the electromagnet, causing the electromagnet to lose its magnetism and prevent it from pushing the magnetic ring to rise. The magnetic ring descends, causing the adapter block to press against the upper surface of the adapter base. This allows the controller to drive the electric push rod to be energized through the adapter base, the adapter block, and the second wire. This drives the piston rod to move, pushing the push block down and causing the transmission rod to pull the movable terminal, allowing it to be transferred to the interface connected to the backup power supply, thus ensuring automatic power switching.

[0014] 2. This low-cost PC-grade dual-power automatic transfer switch improves the stability of terminal movement by having a guide block slide along the inner wall of the guide groove, while the connecting rod allows two adjacent terminals to move synchronously, and the top rod and insulating pressure plate ensure that the connected interface remains sealed to prevent leakage.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Reference Figure 1-4 A low-cost PC-grade dual-power automatic transfer switch includes a switch housing 1. Multiple interfaces 2 are provided on the upper and lower inner walls of the switch housing 1. Multiple terminals 3 are slidably provided on the inner wall of the switch housing 1. The tops of the terminals 3 are in contact with the upper interface 2. A wire 4 is electrically connected to the bottom of the terminal 3. A connecting end cap 5 is electrically connected to the opposite side of the lower interface 2 and the wire 4. An electric push rod 6 is fixedly connected to the top inner wall of the switch housing 1. A push block 7 is fixedly connected to the piston rod end of the electric push rod 6. A transmission rod 8 is hinged to the side wall of the push block 7. The end of the transmission rod 8 facing away from the push block 7 is hinged to the side wall of one of the terminals 3.

[0023] A housing 13 is fixedly connected to the bottom inner wall of the switch housing 1. A controller 14 is fixedly connected to the bottom inner wall of the housing 13. A first wire 15 is electrically connected to the side wall of the connecting end cover 5. An electromagnet 16 is fixedly connected to the inner wall of the housing 13. The electromagnet 16 is electrically connected to the first wire 15. An adapter 17 is fixedly connected to the top inner wall of the controller 14. A second wire 18 is electrically connected to the side wall of the electric push rod 6. One end of the second wire 18, away from the electric push rod 6, extends to the upper surface of the adapter 17. The wiring terminal of the controller 14 extends to the upper surface of the adapter 17.

[0024] A magnetic ring 19 is provided above the electromagnet 16. The side wall of the magnetic ring 19 is slidably disposed on the inner wall of the box 13. A converter block 20 is fixedly connected to the inner wall of the magnetic ring 19. A converter wire is provided inside the converter block 20. The bottom of the converter block 20 is disposed above the converter seat 17.

[0025] In use, when the circuit power is cut off, the first wire 15 cannot energize and magnetize the electromagnet 16, causing the electromagnet 16 to lose its magnetism and be unable to push the magnetic ring 19 to rise. The magnetic ring 19 descends and causes the adapter block 20 to press against the upper surface of the adapter seat 17. This allows the controller 14 to drive the electric push rod 6 to be energized through the adapter seat 17, the adapter block 20, and the second wire 18. This drives the piston rod to move and push the push block 7 down, causing the transmission rod 8 to pull the movable terminal 3, which can be transferred to the interface 2 connected to the backup power supply, ensuring automatic power switching.

[0026] Example 2

[0027] Reference Figure 1-4 Guide blocks 9 are fixed on the side walls of multiple terminals 3 respectively. A guide groove is opened on the inner wall of the switch housing 1. The guide blocks 9 are slidably disposed on the inner wall of the guide groove. A connecting rod 10 is fixedly connected to one side of each of the two terminals 3. A top rod 11 is fixedly connected to the side walls of multiple terminals 3 respectively. An insulating pressure plate 12 is fixedly connected to the end of the top rod 11 away from the terminal 3. The insulating pressure plate 12 is pressed tightly at the bottom of the upper interface 2.

[0028] The guide block 9 slides along the inner wall of the guide groove, which can improve the stability of the movement of the terminal 3, while the connecting rod 10 can make two adjacent terminals 3 move synchronously. The top rod 11 and the insulating pressure plate 12 can ensure that the connected interface 2 is sealed to prevent leakage.
