[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. 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.

[0019] Example 1 One implementation method of this utility model is a combined connector terminal, such as... Figures 1 to 7 As shown, it includes: a female connector 1 and a male connector 2; a female connector 11 is provided on one side of the female connector 1, and a male connector 21 is provided on one side of the male connector 2.

[0020] The female connector 11 is provided with a first main pin 112, a first spring 111 and several signal pins; the male connector 21 is provided with a second main pin 212, a second spring 211 and several signal springs.

[0021] When the female connector 11 and the male connector 21 are connected, the first main pin 112 and the second spring 211 are connected, the second main pin 212 is connected to the first spring 111, and each signal pin is connected to the corresponding signal spring.

[0022] In this embodiment, the signal pins include a first signal pin 113 and a second signal pin 114; the signal spring includes a first signal spring 213 and a second signal spring 214. The first signal pin 113 and the second signal pin 114 are arranged in parallel and positioned between the first main pin 112 and the first spring 111; similarly, the first signal spring 213 and the second signal spring 214 are positioned between the second main pin 212 and the second spring 211. The first main pin 112 and the second main pin 212 are used to transmit operating current, and the first signal pin 113 and the second signal pin 114 are used to transmit detection signals.

[0023] Specifically, the female connector 11 also includes a first connecting cavity 115, a second connecting cavity 116 and a third connecting cavity 117; the first main pin 112, the first spring 111 and the signal pin (i.e. the first signal pin 113 and the second signal pin 114) are respectively disposed in the first connecting cavity 115, the second connecting cavity 116 and the third connecting cavity 117.

[0024] The male connector 21 includes a first connecting post 215, a second connecting post 216 and a third connecting post 217; a second spring 211, a second main pin 212 and signal springs (a first signal spring 213 and a second signal spring 214) are respectively disposed in the first connecting post 216, the second connecting post 215 and the third connecting post 217.

[0025] When the female connector 11 and the male connector 21 are connected, the first connecting cavity 115 is connected to the first connecting post 215, the second connecting cavity 116 is connected to the second connecting post 216, and the third connecting cavity 117 is connected to the third connecting post 217. At this time, the outer walls of the first connecting post 215, the second connecting post 216, and the third connecting post 217 respectively come into contact with the inner walls of the first connecting cavity 115, the second connecting cavity 116, and the third connecting cavity 117 through friction, making the connection between the female connector 1 and the male connector 2 stable and not easy to loosen. Moreover, the cavity isolation design physically isolates the power circuit and the signal circuit, effectively avoiding mutual electromagnetic interference and ensuring the integrity and accuracy of signal transmission.

[0026] Furthermore, the front ends of the first main pin 112, the second main pin 212, and the signal pin are all chamfered to ensure smooth insertion. Both the first spring 111 and the second spring 211 adopt a multi-lobed structure, and each multi-lobed structure has a corresponding sheath on its outer side. The innovative structure of the pins and springs of the female connector 11 and the male connector 21, combined with the multi-lobed structure of the springs, provides continuous and uniform elastic contact pressure, significantly increasing the effective contact area, thereby reducing contact resistance, ensuring the stability and reliability of the connection, and exhibiting excellent vibration resistance.

[0030] Specifically, the female terminal block 12 includes a first wiring cavity 125, a second wiring cavity 126, and a third wiring cavity 127; the male terminal block 22 includes a fourth wiring cavity 225, a fifth wiring cavity 226, and a sixth wiring cavity 227.
