Description

Motor-driven cam production three-phase electrical relay
Technical field
The utility model relates to a kind of three-phase electrical relay, is specifically related to a kind of motor-driven cam production three-phase electrical relay, belongs to field of electronic devices.
Background technology
Relay is a kind of electric control device, is when the change of input variable reaches regulation requirement, makes controlled volume that a kind of electrical equipment of predetermined Spline smoothing occurs in electric output circuit.It has control system and by the interactive relationship between control system.Usually be applied in the control circuit of automation, it is actually the one " automatic switch " going to control big current running with small area analysis, is use one of control element very widely.
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, the motor-driven cam production 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 provided with straight spur gear (2) by the output shaft of direct current machine (1), straight spur gear (2) engages with straight spur gear (3), straight spur gear (3) and 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 gear only has the part gear teeth), straight spur gear (5) and cylindrical cam (6) join together, straight pin (7) contacts with the cam path higher pair of cylindrical cam (6), straight pin (7) and pull bar (8) join together, pull bar (8) and three moving electrodes (9) are fixed together, it is characterized in that: described motor (1) forward and reverse rotation, by the engagement of described straight spur gear (2) and straight spur gear (3), and straight spur gear (4) engages with straight spur gear (5), cylindrical cam (6) described in drive rotates, straight pin (7) drives pull bar (8) to do reciprocating linear motion, pull bar (8) and three moving electrodes (9) combine as a whole, thus realize closed with hard-wired three stationary electrodes (10) of housing (11) and disconnect, namely the closed control with disconnecting to three-phase circuit is achieved.
Feature of the present utility model is: structure is simple, compact, design and manufacture convenient, 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 is the utility model structural representation;
When accompanying drawing 2 is the utility model three-phase electrical relay three moving electrodes (9) with three stationary electrode (10) closure states, the structural representation of straight pin (7) and pull bar (8) status.
When accompanying drawing 3 is the utility model three-phase electrical relay three moving electrodes (9) with three stationary electrode (10) off-states, the structural representation of straight pin (7) and pull bar (8) status.
Embodiment
With reference to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, motor-driven cam production three-phase electrical relay architectural feature is: direct current machine (1) is arranged in housing (11), the output shaft of motor (1) is provided with straight spur gear (2), straight spur gear (2) engages with straight spur gear (3), straight spur gear (3) and 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 gear only has the part gear teeth), this partial gear and cylindrical cam (6) are integrated, straight pin (7) contacts with the cam path higher pair of cylindrical cam (6), straight pin (7) and pull bar (8) join together.It is characterized in that: described motor (1) forward and reverse rotation, by the engagement of described straight spur gear (2) and straight spur gear (3), and straight spur gear (4) engages with straight spur gear (5), cylindrical cam (6) described in drive rotates, straight pin (7) drives pull bar (8) to do reciprocating linear motion, pull bar (8) and three moving electrodes (9) combine as a whole, thus realize closed with hard-wired three stationary electrodes (10) of housing (11) and disconnect.When three moving electrodes (9) are in closed or off-state with three stationary electrodes (10), the Cylindrical Surfaces Contact of straight spur gear (4) and straight spur gear (5), the gear teeth of straight spur gear (4) skid on the smooth, cylindrical peripheral surface of straight spur gear (5), cylindrical cam (6) transfixion, (i.e. self-locking) is rotated because pull bar (8) cannot promote cylindrical cam (6), therefore three-phase electrical relay is stablized in closed or off-state, reliably, is avoided the misoperation of relay.
When accompanying drawing 1 and accompanying drawing 2 are three moving electrodes (9) with three stationary electrode (10) closure states, the structural representation of cylindrical cam (6), straight pin (7), pull bar (8) status.
When three-phase electrical relay three moving electrodes (9) will disconnect with three stationary electrodes (10), motor (1) rotates, straight spur gear (2) engages with straight spur gear (3), straight spur gear (4) engages with another straight spur gear (5), cylindrical cam (6) rotates, drive straight pin (7) and pull bar (8) rectilinear movement, thus drive three moving electrodes (9) and three stationary electrodes (10) to disconnect.
As shown in Figure 3, when three-phase electrical relay three moving electrodes (9) will close with three stationary electrodes (10), motor (1) and aforementioned counter-rotation, straight spur gear (2) engages with straight spur gear (3), straight spur gear (4) engages with another straight spur gear (5), cylindrical cam (6) and aforementioned counter-rotation, drive straight pin (7) and pull bar (8) to do to move linearly with aforementioned opposite direction, thus drive three moving electrodes (9) to close with three stationary electrodes (10).
Because when closing or disconnect, because straight spur gear (4) can not drive straight spur gear (5) to rotate, so straight spur gear (5) and cylindrical cam (6) are in halted state, and pull bar (8) cannot promote cylindrical cam (6) rotation (i.e. self-locking), therefore the closed or off-state of three-phase electrical relay is locked, stable working state, reliable, avoid the misoperation of three-phase electrical relay.
Reality of the present utility model uses and is not limited to embodiment.Also have various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
