Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figures 1 to 4, it is a kind of to operate light non-maintaining disconnecting switch, including base 5.The base 5 is strip
Shape, provided with several mounting holes, easily it can be bolted in line bar.One end of the base 5 is provided with static contact 3,
The other end is provided with dynamic contact portion part 1.The both sides of the static contact 3 and dynamic contact portion part 1 difference connection line, meanwhile, the dynamic contact portion part 1
Can under external force transverse shifting and with the static contact combine or separate, realize the break-make of circuit.
The static contact 3 is L-shaped, is connected by insulator 2 with the base 5.The lateral ends of the static contact 3 are provided with and connect
Line pile crown 6, in that context it may be convenient to be connected with circuit.
The dynamic contact portion part 1 includes guide rail 11 and the attachment 12 being matched therewith.The cross section of the guide rail 11 is
I-shaped, it is connected by insulator 2 with the base 5.The cross section of the attachment 12 is " Jiong " font, can be consolidated
It is connected on the guide rail 11, and can be slided along the guide rail 11.The both sides of the attachment 12 are respectively equipped with one piece of electric conductor 13.
Every piece of electric conductor 13 is bolted on the attachment 12, and front end is respectively equipped with an arc pawl.The two panels arc
Pawl collectively forms moving contact 14, can be with the active link of static contact 3.Moreover, the static contact 3 and the phase of moving contact 14
To one side be adverse slope shape, the clearance gap between the two panels arc pawl front end is less than the width of the static contact 3, makes described
Moving contact 14 can rely on elasticity to wrap the static contact 3, it is ensured that both good contacts.
The top of the moving contact 14 is provided with divide-shut brake closedown structure 4, can lock or unlock with the static contact 3.
The divide-shut brake closedown structure 4 includes hook 41 and operation ring 42.The operation ring 42 is horizontal U-shaped, and a side is fixed on institute
State the upper surface of attachment 12.The hook 41 is horizontal L-shaped, and middle part is connected by rotary shaft 43 and the activity of operation ring 42
Connect, front end is provided with the crotch that can catch on the upper end of static contact 3, and rear end passes through blocking bolt 44 and back-moving spring 45 and the behaviour
Make the one end of ring 42 away from the attachment 12 to be connected.
