General mechanical relay is formed primarily of drive unit and electrode two large divisions.Relay in the market after powered up, can impulse current be produced due to during access big current, can magnetic field be produced between moving electrode and stationary electrode, likely make moving electrode and stationary electrode depart from, thus cause relay misoperation to be done, destroy the normal operating conditions of relay.
Utility model content
Based on the described shortcoming of conventional relay in the market, the utility model provides a kind of structure simple, can make that three-phase electrical relay is stable under operating state that is closed or that disconnect, motor-driven single sheave three-phase electrical relay of reliably working.
For achieving the above object, the utility model adopts following technical measures:
This three-phase electrical relay is driven by direct current machine (1), the output shaft of motor (1) is provided with worm screw (2), worm screw (2) engages with worm gear (3), worm gear (3) and a straight spur gear (4) join together, straight spur gear (4) engages with another straight spur gear (5), straight spur gear (5) is partial gear (namely this gear only has the part gear teeth), incomplete straight spur gear (5) and driver plate (6) are integrated, driver plate (6) and single sheave (8) act on, it is characterized in that: described motor (1) forward and reverse rotation, by described worm screw (2) and worm gear (3), the engaged transmission of straight spur gear (4) and incomplete straight spur gear (5), driver plate (6) described in drive rotates 108 °, driver plate (6) drives single sheave (8) to make counter-rotation 72 ° by finger (7), straight pin (9) on single sheave (8) swings, pull bar (10) is driven to do reciprocating linear motion, pull bar (10) and three moving electrodes (11) combine as a whole, thus realize closed with hard-wired three stationary electrodes (12) of housing (13) and disconnect, namely achieve the closed of three-phase circuit or disconnect control.
Feature of the present utility model is: structure is simple, easy to manufacture, and working stability is reliable, and mechanical efficiency is high, can realize the closed and disconnected action of three-phase electrical relay reposefully, off and on and exactly and realize self-locking.
Accompanying drawing explanation
Accompanying drawing 1, accompanying drawing 2 are the utility model structural representation;
When accompanying drawing 3 is the utility model three-phase electrical relay three moving electrodes (11) with three stationary electrode (12) closure states, the structural representation of driver plate (6), finger (7), single sheave (8), straight pin (9) and pull bar (10) status.
When accompanying drawing 4 is the utility model three-phase electrical relay three moving electrodes (11) with three stationary electrode (12) off-states, the structural representation of driver plate (6), finger (7), single sheave (8), straight pin (9) and pull bar (10) status.
Embodiment
With reference to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, motor-driven single sheave three-phase electrical relay architectural feature is: direct current machine (1) is arranged in housing (13), the output shaft of motor (1) is provided with worm screw (2), worm screw (2) engages with worm gear (3), worm gear (3) and a straight spur gear (4) join together, straight spur gear (4) engages with another straight spur gear (5), straight spur gear (5) is partial gear (namely this gear only has the part gear teeth), straight spur gear (5) and driver plate (6) are integrated, driver plate (6) and single sheave (8) act on, it is characterized in that: described motor (1) forward and reverse rotation, by described worm screw (2) and worm gear (3), the engaged transmission of straight spur gear (4) and straight spur gear (5), driver plate (6) described in drive rotates, driver plate (6) drives single sheave (8) to make counter-rotation by finger (7), straight pin (9) on single sheave (8) swings, pull bar (10) is driven to do reciprocating linear motion, pull bar (10) and three moving electrodes (11) combine as a whole, thus realize closed with hard-wired three stationary electrodes (12) of housing (13) and disconnect.When relay is in closed and disconnected state, straight spur gear (4) and straight spur gear (5) no longer engage, the gear teeth of straight spur gear (4) skid on the smooth, cylindrical peripheral surface of incomplete straight spur gear (5), and driver plate (6) is no longer passed in motion.
