Embodiment Construction
[0022] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] figure 1 It is a schematic diagram of the structure of the 2 / 4 turn coil type longitudinal magnetic contact of the present invention. It includes static contact 1 and moving contact 2 with the same structure and opposite arrangement. The static contact 1 includes a static conductive rod 3-1, a 2 / 4 turn longitudinal magnetic coil 4-1 on the static side, a static support seat 5-1 and a static contact piece 6-1, wherein the static conductive rod 3-1, the static side The 2 / 4-turn longitudinal magnetic coil 4-1 is made of oxygen-free copper, the static support seat 5-1 is made of stainless steel, and the static contact piece 6-1 is made of copper-chromium alloy. The 2 / 4-turn longitudinal magnetic coil 4-1 on the static side is welded to the bottom of the static conductive rod 3-1. Its structure is obtained by optimizing the parameters of th...
