The hybrid electrical self-locking wire-to-board circular connector comprises a male connector and a female connector that cooperate with each other, and a detection mechanism is arranged in the male connector and the female connector, and the cooperation and separation signals when the male and female connectors are plugged in and out are detected through the detection mechanism.

[0032] As shown in Figure 2 , Figure 2 is the structure of the female connector in the hybrid electrical self-locking wire-to-board circular connector. The male connector 1 comprises a male plastic body 11 and a male terminal 12 arranged in the male plastic body 11.

[0033] As shown in Figure 3 , Figure 3 is the structure of the male connector in the hybrid electrical self-locking wire-to-board circular connector. The female connector 2 comprises a female plastic body 21 and a female terminal assembly 22 arranged in the female plastic body 21.

[0034] In the embodiment, the detection mechanism comprises a first terminal 3 and a second terminal 4, the first terminal 3 is arranged in the male connector 1, and the second terminal 4 is arranged in the female connector 2. When the male and female connectors are matched, the first terminal on the male connector is inserted into the second terminal on the female connector. The first terminal 3 and the second terminal 4 are signal terminals.

[0035] In the same axial direction, the male terminal 12 extends to one side of the male plastic body 11, and when the male and female connectors are matched, the male terminal is inserted into the female connector before the first terminal.

[0036] When the female connector 2 and the male connector 1 are matched, the male terminal 12, the female terminal assembly 22, the first terminal 3 and the second terminal 4 are matched and connected.

[0037] Further, the first terminal 3 and the second terminal 4 are arranged in two, and the two second terminals 4 are connected through a signal wire 6. As shown in Figure 4 Figure 4 is a schematic view of the structure of the second terminal in the female connector in the preferred embodiment. The second terminal is fixed at both ends of the same signal wire through a crimping process, realizing the connection of the two signal terminals. After crimping, it is installed in the female plastic body, and the connection between the signal wire and the second terminal is more stable.

[0038] When matched, the two first terminals 3 and the two second terminals 4 are matched and contacted, forming a closed loop.

[0039] The two male terminals are linearly arranged in the male plastic body, the two first terminals are linearly arranged in the male plastic body, and parallel to the linear arrangement of the two male terminals; the module boundary of the male plastic body fixing the first terminal does not exceed the module boundary of the module fixing the two male terminals. The two female terminal assemblies are linearly arranged in the female plastic body, the two second terminals are linearly arranged in the female plastic body, and parallel to the linear arrangement of the two female terminals; the module boundary of the female plastic body fixing the second terminal does not exceed the module boundary of the module fixing the two female terminal assemblies.

[0040] As shown in Figure 5 Figure 5 is a schematic view of the structure of the female terminal assembly in the female connector in the preferred embodiment. The female terminal assembly 22 comprises a female terminal sleeve 22-1, an inner terminal 22-2 and a circular ring 22-3, the inner terminal 22-2 and the circular ring 22-3 are sequentially installed in the female terminal sleeve 22-1, and the inner terminal 22-2 and the circular ring 22-3 are fixed by closing the head of the female terminal sleeve 22-1.

[0043] In the embodiment, according to the structure of the wire-to-board circular connector, the male terminal and the female terminal are both circular terminals. In the limited space, the circular terminals or the circular terminal assembly with high current density are arranged without increasing the product volume. Since the area of the circular terminal is larger than that of any other shape under the same circumference, the current density of the circular terminal is the largest, and the occupied volume is the smallest. Thus, the volume of the connector is greatly reduced, but the current carrying capacity is not affected.

[0044] Through the above structure, an integrated electrical interlocking system is formed in the connector to detect the mating and separation signals of the male and female circular terminals. The working principle is as follows: when the male and female connectors are mated, the male and female signal terminals are contacted after the male and female terminals, and the entire connection system is powered after the male and female signal terminals are contacted; when the male and female connectors are separated, the male and female signal terminals are disconnected before the male and female terminals, and the entire connection system is powered off after the male and female signal terminals are disconnected. In this way, the connection system is not plugged with power, and arc is avoided, which affects the service life and current carrying capacity of the connection system.
