Description

Technical Field

[0001] This utility model relates to the field of DC contactor technology, and in particular to a multifunctional DC contactor structure. Background Technology

[0002] DC contactors play a number of important roles in electrical control systems, mainly including circuit switching, control and protection.

[0003] A DC contactor operates based on electromagnetic principles and consists of an electromagnet, contacts, and a spring. When the electromagnet is energized, it generates a magnetic field that attracts the contacts to close; when the electromagnet loses power, the spring separates the contacts, breaking the circuit.

[0004] Existing DC contactors are only equipped with one set of electrical connection ports, which may not meet the needs of some complex circuits in practical applications. This means that when it is necessary to switch, control or protect between multiple circuits, a single connection port may not be able to do the job, thus limiting the application scenarios and functional expansion of DC contactors. Therefore, the applicant has made a useful design and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the traditional DC contactor design and provide a product that improves applicability and flexibility.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A multifunctional DC contactor structure includes a body, the body having a partition, copper busbars on both sides of the partition, at least two conductive plates on both sides of the partition and connected and fixed to the copper busbars, and the copper busbars having at least two terminal sets.

[0008] Preferably, the body is provided with a stationary contact, which is connected and fixed to the conductive plate.

[0009] Preferably, the conductive plate is provided with a threaded rod that passes through a copper busbar, the threaded rod being threadedly connected to a nut, and the nut pressing the copper busbar tightly onto the conductive plate.

[0010] Preferably, the terminal assembly includes a screw, and the screw is provided with a washer and a spring washer in sequence from bottom to top. The screw is threaded to a nut and abuts against the spring washer.

[0011] Beneficial effects:

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) By installing a copper busbar with a larger cross-sectional area, this utility model can withstand a larger current, thereby enhancing the wiring capacity. In addition, due to the increased contact area between the copper busbar and the air, heat dissipation is effectively promoted, significantly reducing the temperature rise of the wiring port and ensuring the stable operation of the DC contactor in a high-temperature environment.

[0014] (2) This utility model achieves centralized and standardized wiring through the design of copper busbars, which facilitates the parallel or series connection of multiple circuits and greatly improves the application flexibility of DC contactors to meet diverse circuit design needs. In addition, the configuration of copper busbars helps to evenly distribute current, reduce the current burden of individual contacts, effectively reduce the risk of fire caused by overheating, and thus improve the safety performance of the entire electrical system.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0022] Reference example Figure 1 , Figure 2 A multifunctional DC contactor structure includes a body 1, a partition 11, copper busbars 3 on both sides of the partition 11, and at least two conductive plates 2 on both sides of the partition 11, which are connected and fixed to the copper busbars 3. The copper busbars 3 have at least two terminal groups 4. By installing copper busbars 3 with a larger cross-sectional area, it can withstand a larger current, thereby enhancing the wiring capacity. In addition, due to the increased contact area between the copper busbars 3 and the air, heat dissipation is effectively promoted, significantly reducing the temperature rise of the wiring ports and ensuring the stable operation of the DC contactor in high-temperature environments. The design of the copper busbars 3 realizes the centralization and standardization of wiring, which facilitates the parallel or series connection of multiple circuits, greatly improving the application flexibility of the DC contactor to adapt to diverse circuit design needs. Furthermore, the configuration of the copper busbars 3 helps to evenly distribute the current, reducing the current burden of individual contacts and effectively reducing the risk of fire due to overheating, thereby improving the safety performance of the entire electrical system.

[0023] It is worth mentioning that the main body 1 is provided with a stationary contact 5, which is connected and fixed to the conductive plate 2;

[0024] It is worth mentioning that the conductive plate 2 is provided with a threaded rod 21, which passes through the copper busbar 3. The threaded rod 21 is threadedly connected to the nut 6. The nut 6 presses the copper busbar 3 tightly onto the conductive plate 2, and the copper busbar 3 and the conductive plate 2 are tightly connected by the nut 6.

[0025] It is worth mentioning that the terminal block 4 includes a screw 41. From bottom to top, the screw 41 is provided with a washer 42 and a spring washer 43. The screw 41 is threaded to the nut 6 and abuts against the spring washer 43. The wire is wound around the screw 41 or the copper lug is sleeved on the screw 41. The nut 6 and the washer 42 press the wire or copper lug tightly onto the copper busbar 3. The spring washer 43 increases the friction between the nut 6 and the screw 41 to ensure a stable connection.

[0026] The above design scheme can enable the product to achieve the advantages of reduced temperature rise, improved applicability and flexibility.

[0027] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions.
