Abstract
The utility model belongs to a quick-action switch with the forced switch-off function, and a top frame drives a contacting bridge through a quick-action elastic piece and a punching rod to quickly switch on and off a static contacting point. When the welding connection of the contacting point or the elastic piece has the fault, the action force is directly transferred to the movable contacting bridge through forcedly opening a lever. The static contacting point is forced to be switched off to switch off a circuit to ensure the safety. Owing to the module and the diversity of the structure and function, high reliable performance and long lifetime, the quick-action switch with the forced switch-off function is used for the railway locomotive motor train unit and the subway vehicle as the auxiliary controlling switch.
Description
The utility model belongs to the appliance switch of using in a kind of automatic control equipment.Be specially adapted to railway locomotive, motor train unit, railcar, urban light rail, ground mechanically moving (device), as the contact switch of control circuit.
In existing technology, the auxiliary contact contact capacity that railway locomotive adopts is little, and breaking capacity is poor, and it is unreliable to contact, and is easy to generate adhesion, and useful life is short.
The purpose of this utility model is: design a kind of have volume little (lightly), quick-action, easy for installation, breaking capacity big, the switch element that the contact is arranged of fail-self effect, modular railway locomotive, railcar.
The purpose of this utility model realizes in the following manner: a kind of with the quick-action switch of forcing to disconnect, comprise switch base (13), switch base (13) top is provided with the upper frame of falling the T-shape (3), upper frame (3) is provided with back-moving spring (4), switch base (13) middle part is provided with jumper bar (9), jumper bar (9) top is provided with quick-action shell fragment (5), quick-action shell fragment (5) other end is located at upper frame (3) two bottom sides, jumper bar (9) both sides are provided with positive opening lever (1), the fulcrum of lever (2) is located on the switch base (13), jumper bar (9) bottom is provided with movable contact bridge (8), and switch base (13) both sides are provided with normally closed or often open fixed contact (6,7).
Switch base (13) top is provided with installs support plate (12), and upper frame (3) is provided with wheel shelf assembly (11), and fixed contact (6,7) is provided with binding post, and binding post is screw (14) or flat plug (15).
Switch base (13) is outer to be provided with arc-control device, and arc-control device comprises arc-extinguish chamber (16), is provided with magnetic core (17) in the arc-extinguish chamber (16), and arc-extinguish chamber (16) side is provided with pole plate (18).
Movable contact bridge (8) is a double break point-contact type formula with fixed contact (6,7).
Movable contact bridge (8) is auto purification double break point pattern with fixed contact (6,7), and arc movable contact bridge (8) is gone up through the CONTACT WITH FRICTION closure at " V " type fixed contact (6,7).
As the contact switch of control usefulness, when reaching the final position, snap action disconnects the contact, cuts off circuit, and to prevent damage equipment or the life security that threatens operating personnel, this point is vital.In addition, quick-action switch is equipped with the pressure release mechanism, when causing the fault that circuit can't disconnect when contact weld or spring breakage, the power of action is directly passed to touches bridge portion, forces release mechanism can guarantee at once circuit to be cut off by force.The quick-action of contact switch, band are forced release mechanism, and its importance gains public acceptance in the world.The utility model has the advantages that: quick-action type, double break point, big, the modularization of capacity.Auto purification effect and the characteristics of forcing disrupted configuration make it reach highly reliable, the long-life.
