[0026] See also Figure 1-4 The present invention provides a technical solution:

[0027] A circular plug-in connector, comprising a pluggable DC female connector 10 and a DC male connector 20;

[0028] The DC female connector 10 includes a female connector housing 14, a hollow cavity is provided inside the female connector housing 14, one end of the hollow cavity is fixedly connected to a negative electrode connector 17, an insulating layer 16 is fixedly connected inside the negative electrode connector 17, and a positive electrode connector 15 is fixedly connected inside the insulating layer 16, wherein the negative electrode connector 17 is connected to the negative electrode sheet 13, and the positive electrode connector 15 is connected to the positive electrode sheet 12;

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

[0030] In the above, the positive electrode sheet 22 and the negative electrode sheet 23 are connected to the line terminal, and the DC female connector 10 is inserted into the DC male connector 20. As the DC female connector 10 goes deeper, the negative electrode connector 17 and the negative electrode connector 25 are first contacted, and then the positive electrode connector 15 and the positive electrode connector 27 are also contacted, to ensure that the current or signal can pass through with low impedance. At the same time, the insulating layer 16 and the insulating layer 26 effectively isolate the positive and negative electrodes to prevent short circuits.

[0031] Furthermore, in this embodiment, a double-layer card slot 18 is provided inside the female head shell 14, and a card block 28 is provided on the outer surface of the male head shell 21. The card block 28 is card-connected with the female head shell 14 through the card slot 18, thereby further fixing the DC male head 20 inside the DC female head 10.

[0032] Furthermore, in this embodiment, the insulating layer 1 16 and the insulating layer 2 26 are made of polytetrafluoroethylene (PTFE) or epoxy resin material, which effectively isolates the positive electrode from the negative electrode and prevents the occurrence of a short circuit, thereby ensuring that good insulation performance can be maintained even in harsh environments.

[0033] Furthermore, in this embodiment, the other ends of the positive electrode sheet 12 and the negative electrode sheet 13 are connected to the pin 11, and the pin 11 is used to facilitate connection with an external circuit or device.

[0034] Furthermore, in the present embodiment, the negative electrode connector 1 17 and the positive electrode connector 2 27 are both arranged in an arc shape, and the positive electrode connector 1 15 and the negative electrode connector 2 25 are arranged in a straight line. In this way, when the negative electrode connector 1 17 and the negative electrode connector 2 25, and the positive electrode connector 1 15 and the positive electrode connector 2 27 are in the docking process, the arc connector can more smoothly guide the straight connector into the docking position, reducing the friction and resistance during the plugging and unplugging process, which not only improves the convenience of operation, but also helps to extend the service life of the connector. In a vibration or impact environment, the arc connector can better adapt to slight position changes and maintain a stable contact state, which helps to prevent signal interruption or current fluctuation caused by poor contact. The compact design of the arc connector allows the connector to occupy a smaller space while maintaining high performance, which is particularly important for application scenarios with limited space. It is more convenient for blind plugging, has better stability, and is not easy to fall off.

[0035] Working principle: Before the DC female connector 10 and the DC male connector 20 are connected, they are kept in an independent state. The pin 11 of the DC female connector 10 is connected to the corresponding circuit of the external device or system through a circuit board or other connection means, and the line end of the DC male connector 20 is connected to the circuit of the device or system at the other end. At this time, although the circuits at both ends are independent, they are ready for electrical connection. When electrical connection is required, the operator aligns the DC female connector 10 with the insertion port of the DC male connector 20 and pushes the DC female connector 10 smoothly into the DC male connector 20. In this process, it may be necessary to overcome a certain insertion resistance, which is usually generated by the locking mechanism or the tight fit between the connectors to ensure the stability of the connection. As the DC female connector 10 goes deeper, the negative terminal 17 and the negative terminal 2 25 are first contacted, and then the positive terminal 15 and the positive terminal 2 27 are also contacted. The contact surface between these connectors is designed with excellent conductive materials and plating to ensure that the current or signal can pass with low impedance. At the same time, the insulating layer 16 and the insulating layer 26 effectively isolate the positive and negative electrodes to prevent short circuits. The current or signal is transmitted from the line end of the DC male connector 20 to the pin 11 of the DC female connector 10 through the contact surface between the positive connector and the negative connector, and then reaches the external device or system through the circuit board or other connection means. Vice versa, the electrical connection and communication between the devices or systems at both ends are achieved. When the connection needs to be disconnected, the operator unlocks the locking mechanism and then smoothly pulls the DC female connector 10 out of the DC male connector 20. In this process, the contact between the connectors is gradually separated until the electrical connection is completely disconnected.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
