[0048] The base 100 is used to carry electrical parts; the transformer module 200 is arranged on one side of the base 100; the contactor module 300 is arranged on the side of the base 100 away from the transformer module 200; the first end of the conductive wire 400 is connected to the contactor module 300 on the side close to the transformer module 200, and the conductive wire 400 passes through the transformer module 200 and is movably arranged on the base 100.
[0049] In this embodiment, the conductive cord 400, as a new type of power transmission material, has attracted wide attention in the power industry due to its unique softness and bendability. The conductive cord 400 is usually woven from multiple strands of fine copper wires, and the outer layer is wrapped with insulating material.

Finally, the contactor module 300 is connected by a conductive soft wire 400, which passes through the transformer module 200 and is movably set on the base 100 to realize the transmission of electrical signals. By adopting the conductive soft wire 400 to replace the traditional hard connection method, not only the volume of the AC contactor is reduced, but also the flexibility and reliability of the connection are improved.
[0054] Combined with reference Figure 2 and Figure 6 As shown, further, another embodiment of the utility model provides an AC contactor, based on the above Figure 2 , Figure 3 , Figure 5 as well as Figure 6In the embodiment shown, there are a plurality of conductive flexible wires 400, an insulating protrusion 110 is provided on the base 100, the mutual inductor module 200 is mounted on the insulating protrusion 110, and the plurality of conductive flexible wires 400 are arranged through the insulating protrusion 110, and the insulating protrusion 110 is used to insulate the plurality of conductive flexible wires 400 from each other.

When space is limited, a conductive flexible wire 400 with a shorter length and a smaller bending radius can be selected to optimize the layout.

In addition, the wiring hole on the transformer body 210 is used to lead out the signal line, which is convenient for connection with the control part of the circuit board 600.
[0063] In this embodiment, the central insulating component 220 is an important component of the transformer module 200.

The contact assembly 340 includes components such as a first static contact 341, a second static contact 342, and an action connecting rod 343. The first static contact 341 is electrically connected to the conductive soft wire 400 in a one-to-one correspondence, and is used to connect to an external circuit. The second static contact 342 is electrically connected to the first copper bar 500 in a one-to-one correspondence, and is used to transmit current to other parts of the contactor module 300. A plurality of moving contacts 344 are provided on the action connecting rod 343. When the action connecting rod 343 moves axially, the moving contact 344 will simultaneously approach or move away from the first static contact 341 and the second static contact 342, thereby realizing the conduction or disconnection between the conductive soft wire 400 and the first copper bar 500. This design makes the action of the contact assembly 340 more synchronous and coordinated, and improves the accuracy and reliability of contact closing and disconnection. At the same time, by optimizing the structure and material of the contact assembly 340 , the contact resistance and wear can be reduced, and the service life and stability of the contact can be improved.
[0082] In actual applications, the selection, design and parameter setting of the contact assembly 340 need to be comprehensively considered according to the use conditions and performance requirements of the AC contactor. For example, the material of the static contact and the moving contact 344 needs to have good conductivity and wear resistance to ensure good contact effect and long service life. The structure and action mode of the action connecting rod 343 also need to be adjusted and optimized according to specific control requirements. In addition, in order to improve the heat dissipation performance and arc resistance of the contact assembly 340, special heat dissipation structures and arc extinguishing measures can also be adopted. Through these optimization measures, the performance and reliability of the AC contactor can be further improved to meet various complex application scenarios and requirements.
[0083] In addition, the contact effect can be improved by reasonably designing and optimizing the contact area and contact pressure of the contact assembly 340, thereby reducing the contact resistance and reducing energy loss. Secondly, the contact assembly 340 has a fast and stable action speed, can achieve rapid closing and disconnection, and improves the response speed and work efficiency of the device.

[0085] In this embodiment, the circuit board 600 of the AC contactor is used as a core component of electrical control and signal processing. By setting a second connection terminal 610, an electrical connection with the transformer module 200 is achieved. This design enables the transformer module 200 to detect parameters such as the current and voltage of the AC contactor in real time, and transmit the signal to the circuit board 600 for processing. Through the analysis and processing of the signal by the circuit board 600, the precise control and protection function of the AC contactor can be achieved. In addition, the circuit board 600 is also provided with a plurality of pins 620, which are arranged through the base 100 and are used to connect with external devices or systems to realize data transmission and exchange. The design of the pins 620 makes the connection more stable and reliable, and improves the stability and reliability of the equipment. This design enables the AC contactor to not only have electrical control and switching functions, but also have the ability of real-time detection and data processing, which improves the intelligence and automation level of the equipment.
[0086] In practical applications, the selection and design of the circuit board 600 need to be comprehensively considered according to the performance requirements and use environment of the AC contactor. For example, it is necessary to select a microprocessor and peripheral circuit with high performance and stability to ensure that the circuit board 600 can perform signal processing and control normally. At the same time, it is also necessary to consider the layout and wiring method of the circuit board 600 to reduce electromagnetic interference and signal loss. In addition, in order to improve the heat dissipation performance and anti-electromagnetic interference ability of the equipment, special heat dissipation structures and shielding measures can also be adopted. Through these optimization measures, the performance and stability of the AC contactor can be further improved to meet various complex application scenarios and requirements.
