Description
Technical field
The present invention relates to a kind of catalyst, particularly relate to the mechanical interlocking module structure of a kind of directional contactor.
Background technology
Catalyst refers to utilize coil to flow through current induced magnetic field in industrial electro, makes contact closure, to reach to control the electricity of load
Device.After contactor coil is energized, coil current can produce magnetic field, and it is dynamic that the magnetic field of generation makes fixed core produce electromagnetic attraction attraction
Iron core, and drive contacts of contactor action, normally-closed contact disconnects, and normally opened contact closes, and both are linkages.Work as coil blackout
Time, electromagnetic attraction disappears, and armature discharges under the effect of release spring, makes contact restore, and normally opened contact disconnects, normally-closed contact
Guan Bi.Reversible catalyst is a kind of reversible A.C. contactor of machinery for controlling relatively high power motor forward and backward, by two
Standard type catalyst and a mechanical interlocking module are constituted, and mechanical interlocking module is connected between two catalysts, when therein one
During individual Contactor Starting adhesive, the control bar of two catalysts is made to interlock by mechanical interlocking module.
In the prior art, a kind of mechanical interlocking module is to include shell, beat heart part and push rod, this mechanical interlocking mould
Block is that the bar that controls using seesaw principle to realize two catalysts is mutually locked, and its shell is by two different part structures
Becoming, two parts are provided with the pin-and-hole structure that can cooperate, and two parts couple composition shell in pin-and-hole occlusion mode, and depend on
Bad U-shaped part card is from bilaterally-chucked shell, and dependence U-shaped part couples the catalyst of both sides, and this mechanical interlocking module is altogether containing 6
Plant/7 parts.Another kind of mechanical interlocking module is to use engaged swing arm to be used as lockable mechanism, and its shell is by 2
Plant/3 parts and couple composition in lockhole occlusion mode, and by U-shaped part from bilaterally-chucked, and rely on U-shaped part connection both sides
Catalyst, this mechanical interlocking module contains 6 kinds/10 parts containing 6 kinds/7 parts altogether.Above two mechanical interlocking module
Kind and the quantity of part are the most more, and this can make the cost of manufacture of product increase.Another mechanical interlocking module, its locking machine
Structure is cylinder and push rod, and push rod is provided with a step, utilizes the step on push rod to realize locking, and cylinder is contained in housing,
Cylindrical rotating direction is mechanical interlocking module thickness direction, namely mechanical interlocking module and the coupling direction of two side contactors,
Owing to cylinder needs have certain diameter dimension, this allows for wider (the i.e. machinery connection in the connection interval between two catalysts
The gauge of lock module is bigger), and, shell is 1 labyrinth (mould needs distance to loose core) part, by thickness
Limiting and push rod assembles and limits, the limit rib on cylinder rotating direction is little and weak, limited strength；And wanting due to structure
Ask push rod need to set elastic spacing convex tendon, frangibility during assembling；It addition, need on shell arrange bayonet socket and jointly joined by independent fastener
Connect two side contactors；And this mechanical interlocking module needs 4 kinds/6 parts altogether.
Summary of the invention
