Description of drawings
Fig. 1 is the structural representation of magneto distribution isolating switch.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1, a kind of magneto distribution isolating switch comprises:
Be fixed on the static contact and insulation pillar 82 on the described pedestal 9;
Be fixed on the moving contact insulation column 81 on the described pedestal 9;
Stationary contact and described static contact and insulation pillar 82 switch main bodies 1 hinged, that comprise melt;
Be fixed on the metallic object 2 of the movable contact head end of described switch main body 1;
Be hinged on the declutch shaft 3 of the movable contact head end of described switch main body 1, under preferable situation, declutch shaft 3 is connected with the movable contact head end of described switch main body 1 with riveted way;
Be fixed on the metallic cavity 4 on the described moving contact insulation cylinder;
Place the metal-doped magnet 5 in the described metallic cavity 1;
Wherein, the pin joint of described declutch shaft 3 and described switch main body 1 is to the distance of described declutch shaft 3 one ends, and after described magneto panel switches closure, described switch main body 1 is to the beeline of described metallic cavity 4.Then, when magneto distribution isolating switch is closed, by the magnetic force of metal-doped magnet 5, can metallic object 2 and metallic cavity 4 is fixing; When needing cut-off switch,, can like a cork switch be disconnected by leverage by pulling declutch shaft 3.Under preferable situation, an end of described declutch shaft contacts with described metallic object and described metallic cavity when described magneto distribution isolating switch is closed, and then when switch closure, the position of declutch shaft 3 can be fixed, and can not rotate around pin joint.
Further, the stationary contact of described switch main body 1 is hinged on the cylinder 7, and described cylinder 7 is fixed on the fixed contact substrate 62, and described fixed contact substrate 62 is fixed on the described static contact and insulation cylinder 82, can connect external cable on the described fixed contact substrate 62.
Further, described metallic cavity 4 is fixed on the moving contact substrate 61, can connect external cable on the described moving contact substrate 61.
Further, the affixed eseparation ring 31 of the other end of described declutch shaft 3 is convenient to the application of force.
Further, described metal-doped magnet 5 is a ferro-aluminum roc magnet, and described metallic cavity is the pure iron metallic cavity, and described metallic object is an armature block.The magnetic force of ferro-aluminum roc magnet is stronger, and armature and pure iron are magnetic material preferably, can guarantee the dynamics of switch closure.
Further, also be fixed with a columnar projections on the described moving contact substrate 61, the notch on the adaptive described switch main body of described columnar projections.So that determine the make position and the conduction of switch main body 1 better.
