[0002] A DC connector, or DC power interface, is a connection port that provides DC power to electronic devices. With its stable power supply and simple connection method, it is widely used in many fields, such as laptops, mobile phones, home appliances, cameras and monitoring equipment, as well as automation equipment and instruments in the industrial field. It is an indispensable part of modern industry and daily life, widely used for power connections.

[0003] However, existing technologies have some problems. The insertion process requires precise alignment, which can lead to breakage during use. Furthermore, existing technologies are prone to the locking mechanism breaking or cracking, causing the male connector to detach. Therefore, it is necessary to provide a new technology that can solve these problems.

[0004] In view of this, a circular mating connector is provided to overcome the above-mentioned defects. Utility Model Content

[0026] Please see Figure 1-4 In this invention, a technical solution is provided:

[0027] A circular mating connector includes a removable DC female connector 10 and a DC male connector 20;

[0028] The DC female connector 10 includes a female connector housing 14, which has a hollow cavity. One end of the hollow cavity is fixedly connected to a negative terminal connector 17. An insulating layer 16 is fixedly connected inside the negative terminal connector 17, and a positive terminal connector 15 is fixedly connected inside the insulating layer 16. The negative terminal connector 17 is connected to the negative electrode plate 13, and the positive terminal connector 15 is connected to the positive electrode plate 12.

[0029] The DC male connector 20 includes a male connector housing 21, a negative terminal connector 25 is fixedly connected inside the male connector housing 21, an insulating layer 26 is fixedly connected inside the negative terminal connector 25, and a positive terminal connector 27 is fixedly connected inside the insulating layer 26. The positive terminal connector 27 is connected to the positive electrode plate 22, and the negative terminal connector 25 is connected to the negative electrode plate 23.

[0030] In the above configuration, positive electrode 22 and negative electrode 23 are connected to the line terminals. DC female connector 10 is inserted into DC male connector 20. As DC female connector 10 is inserted deeper, negative connector 17 and negative connector 25 first make contact, followed by positive connector 15 and positive connector 27, ensuring that current or signal can pass through with low impedance. Simultaneously, insulating layers 16 and 26 effectively isolate the positive and negative electrodes, preventing short circuits.

[0031] In this embodiment, the female connector housing 14 is provided with a double-layer slot 18 inside, and the male connector housing 21 is provided with a snap-fit ​​block 28 on its outer surface. The snap-fit ​​block 28 snaps into the female connector housing 14 through the slot 18, thereby further fixing the DC male connector 20 inside the DC female connector 10.

[0032] In this embodiment, the first insulating layer 16 and the second insulating layer 26 are made of polytetrafluoroethylene (PTFE) or epoxy resin. They effectively isolate the positive and negative electrodes, prevent short circuits, and ensure good insulation performance even in harsh environments.

[0033] In this embodiment, the other end of the positive electrode plate 12 and the negative electrode plate 13 is connected to pin 11, which facilitates connection to external circuits or devices.

[0034] In this embodiment, both the negative connector 17 and the positive connector 27 are arc-shaped, while the positive connector 15 and the negative connector 25 are straight. Thus, during the mating process of the negative connector 17 and the negative connector 25, and the positive connector 15 and the positive connector 27, the arc-shaped connectors can more smoothly guide the straight connectors into the mating position, reducing friction and resistance during insertion and removal. This not only improves operational convenience but also helps extend the connector's lifespan. In vibration or impact environments, the arc-shaped connectors can better adapt to minute positional changes and maintain a stable contact state. This helps prevent signal interruption or current fluctuations caused by poor contact. The compact design of the arc-shaped connectors allows the connector to maintain high performance while occupying less space, which is particularly important for space-constrained applications. It also facilitates blind mating, provides better stability, and is less prone to detachment.

[0035] Operating Principle: Before the DC female connector 10 and DC male connector 20 are connected, they remain independent. Pin 11 of the DC female connector 10 is connected to the corresponding circuitry of an external device or system via a circuit board or other connection means, while the line terminal of the DC male connector 20 is connected to the circuitry of the other device or system. At this point, although the circuits at both ends are independent, they are both ready for electrical connection. When an electrical connection is needed, the operator aligns the DC female connector 10 with the insertion port of the DC male connector 20 and smoothly pushes the DC female connector 10 into the DC male connector 20. During this process, some insertion resistance may need to be overcome, which is usually generated by a locking mechanism or a tight fit between the connectors to ensure a stable connection. As the DC female connector 10 is inserted deeper, the negative terminal 17 and the negative terminal 25 first make contact, followed by the positive terminal 15 and the positive terminal 27. The contact surfaces between these connectors are designed with excellent conductive materials and plating to ensure that current or signals can pass through with low impedance. Meanwhile, insulating layer 16 and insulating layer 26 effectively isolate the positive and negative electrodes, preventing short circuits. Current or signals are transmitted from the line end of DC male connector 20 to pin 11 of DC female connector 10 through the contact surface between the positive and negative terminals, and then reach external devices or systems via circuit boards or other connection methods. Conversely, this achieves electrical connection and communication between the two devices or systems. When disconnection is required, the operator unlocks the locking mechanism and then smoothly pulls DC female connector 10 out of DC male connector 20. During this process, the contacts between the connectors gradually separate until the electrical connection is completely broken.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
