[0024] Reference example Figures 1 to 5 , a dual power automatic transfer switch that is easy to wire, includes a body 1, a plurality of wiring chambers 11 are provided at both ends of the body 1, the wiring chamber 11 is provided with a static spring 2, the static spring 2 is provided with a spring 3, one end of the spring 3 is provided with at least one supporting portion 31, and the other end of the spring 3 is provided with at least one contact portion 32, the static spring 2 is provided with a through hole 21 for accommodating the supporting portion 31 and the contact portion 32, one side of the through hole 21 is provided with an inclined pressure-bearing portion 22, and the contact portion 32 abuts against each other, the wiring chamber 11 is provided with an inclined wire hole 12, and faces the contact portion 32, a liftable pressing member 4 is provided above the wiring chamber 11, and is provided between the contact portion 32 and the wiring chamber 11, for pushing the contact portion 32 and leaving the pressure-bearing portion 22;

[0025] It is worth mentioning that a curved extension portion 23 is provided at one end of the static spring piece 2, and a curved top plate 24 is provided at the other end of the static spring piece 2, which abuts against the support portion 31. The extension portion 23 cooperates with the moving contact in the body 1, and the top plate 24 further provides support for the support portion 31.

[0026] It is worth mentioning that the support portion 31 is provided with a curved hook portion 311 that abuts against the static spring piece 2 , and the hook portion 311 prevents the spring piece 3 from escaping from the through hole 21 ;

[0027] It is worth mentioning that the top of the wiring chamber 11 is provided with a sliding hole 13 for the pressing member 4 to pass through, and limiting grooves 14 are provided on both sides of the wiring chamber 11. A fitting portion 15 is provided at one end of the wiring chamber 11 and abuts against the abutting portion 32. The sliding hole 13 provides a guide for the pressing member 4, and the limiting groove 14 limits the range of movement of the pressing member 4 in rising and falling. The fitting portion 15 cooperates with the abutting portion 32.

[0028] It is worth mentioning that limit blocks 41 are provided on both sides of the pressing member 4 and are slidably arranged in the limit groove 14. The pressing member 4 is provided with an inclined surface 42, which faces the interference portion 32 and is located above the spring 3. A pressing portion 43 is provided on the end face of the pressing member 4. The inclined surface 42 gradually pushes the interference portion 32 away from the pressure-bearing portion 22. The pressing portion 43 facilitates the user to operate the pressing member 4.

[0029] The operating principle of the present invention is now described as follows:

[0030] By applying downward pressure to the pressing portion 43, the inclined surface 42 enters between the abutting portion 32 and the end surface of the wiring chamber 11. As the pressing member 4 gradually descends, the inclined surface 42 pushes the abutting portion 32 further away from the pressure-bearing portion 22, causing the spring 3 to gradually accumulate energy until the limit block 41 abuts the bottom of the limit groove 14, and the pressing member 4 can no longer be pushed downward.

[0031] Insert the exposed part of the wire through the wire hole 12 and between the pressure-bearing part 22 and the contact part 32. Release the force applied to the pressing part 43. The spring 3 releases the elastic force to press the contact part 32 down to press the exposed part of the wire against the pressure-bearing part 22, and push the pressing member 4 back to its original position, thus completing the quick wiring.

[0032] If the exposed portion of the wire does not enter between the pressure-bearing portion 22 and the contact portion 32, the contact portion 32 will press the wire tightly against the fitting portion 15, and quick wiring can still be achieved. At the same time, the contact portion 32 is electrically connected to the exposed portion of the wire and still has conductivity.

[0033] The above design solution can enable the product to achieve the advantages of fast wiring and stable electrical connection.

[0034] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
