Example Embodiment
[0011] The specific embodiments, structures, features and effects of the present invention are described in detail below in conjunction with the drawings and simple embodiments.
[0012] Such as figure 1 As shown, an energy-saving multi-contact group DC contactor is composed of an injection-molded insulating housing 1, a drive motor 2, and multiple sets of static and moving contacts. The drive motor 2 installed inside the injection-molded insulating housing 1 passes The forward or reverse rotation drives the screw 3 to rotate, thereby driving the push rod 4 to produce a push or pull mechanical movement, thereby driving the movable contact group on the movable contact arm 19, namely the movable contact 8, the movable contact 9, The moving contact 12, the moving contact 13, the moving contact 16, and the moving contact 17 move left and right between the static contact groups at the same time to achieve the purpose of circuit switching. The photoelectric position sensor 6 detects th...
