Description
Technical field
The utility model relates to a kind of relay, is specifically related to a kind of motor-driven cam orientation one-phase 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 relay is stable under operating state that is closed or that disconnect, the motor-driven cam orientation one-phase relay of reliably working.
For achieving the above object, the utility model adopts following technical measures:
This relay is provided with straight spur gear (3) by the output shaft of direct-flow micromachine (2), straight spur gear (3) engages with straight spur gear (4), straight bevel gear (5) and straight spur gear (4) join together, straight bevel gear (5) engages with another straight bevel gear (6), straight bevel gear (6) is partial gear, straight bevel gear (6) and cam (7) join together, straight pin (8) contacts with the cam path higher pair of cam (7), straight pin (8) and pull bar (9) join together, pull bar (9) and moving electrode (11) are fixed together, it is characterized in that: described motor (2) forward and reverse rotation, by the engagement of described straight spur gear (3) and straight spur gear (4), and straight bevel gear (5) engages with straight bevel gear (6), cam (7) described in drive rotates, straight pin (8) drives pull bar (9) to do reciprocating linear motion, pull bar (9) and moving electrode (11) combine as a whole, thus realize closed with housing (1) hard-wired stationary electrode (10) and disconnect.
Feature of the present utility model is: structure is simple, compact, design and manufacture convenient, can realize the closed and disconnected action of relay reposefully, 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 relay moving electrode (11) with stationary electrode (10) closure state, the structural representation of straight pin (8) and pull bar (9) status.
When accompanying drawing 3 is the utility model relay moving electrode (11) with stationary electrode (10) off-state, the structural representation of straight pin (8) and pull bar (9) status.
Embodiment
With reference to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, motor-driven cam orientation one-phase relay architectural feature is: direct-flow micromachine (2) is arranged in housing (1), the output shaft of motor (2) is provided with straight spur gear (3), straight spur gear (3) engages with straight spur gear (4), straight spur gear (4) and spur bevel gear (5) join together, spur bevel gear (5) engages with another spur bevel gear (6), spur bevel gear (6) is partial gear, this partial gear and cam (7) are integrated, straight pin (8) contacts with the cam path higher pair of cam (7), straight pin (8) and pull bar (9) join together.It is characterized in that: described motor (2) forward and reverse rotation, by the engagement of described straight spur gear (3) and straight spur gear (4), and straight bevel gear (5) engages with straight bevel gear (6), cam (7) described in drive rotates, straight pin (8) drives pull bar (9) to do reciprocating linear motion, pull bar (9) and moving electrode (11) combine as a whole, thus realize closed with housing (1) hard-wired stationary electrode (10) and disconnect.When moving electrode (11) and stationary electrode (10) are in closed or off-state, the conical surface contact of spur bevel gear (5) and spur bevel gear (6), the gear teeth of spur bevel gear (5) skid on the smooth taper seat of spur bevel gear (6), cam (7) is static, because pull bar (9) cannot actuating cam (7) rotation and self-locking, therefore relay is stablized in closed or off-state, reliably, is avoided the misoperation of relay.
When accompanying drawing 1 and accompanying drawing 2 are moving electrode (11) with stationary electrode (10) closure state, the structural representation of cam (7), straight pin (8), pull bar (9) status.
When relay moving electrode (11) will disconnect with stationary electrode (10), motor (2) rotates, straight spur gear (3) engages with straight spur gear (4), spur bevel gear (5) engages with another spur bevel gear (6), cam (7) rotates, drive straight pin (8) and pull bar (9) rectilinear movement, thus drive moving electrode (11) and stationary electrode (10) to disconnect.
As shown in Figure 3, when relay moving electrode (11) will close with stationary electrode (10), motor (2) and aforementioned counter-rotation, straight spur gear (4) engages with straight spur gear (4), spur bevel gear (5) engages with another spur bevel gear (6), cam (7) and aforementioned counter-rotation, drive straight pin (8) and pull bar (9) to make in aforementioned opposite direction to move linearly, thus drive moving electrode (11) to close with stationary electrode (10).
Think when closing or disconnect, because spur bevel gear (5) can not drive spur bevel gear (6), so spur bevel gear (6) and cam (7) are in halted state, and pull bar (9) cannot actuating cam (7) rotation and self-locking, therefore the closed or off-state of relay is located, stable working state, reliable, avoid the misoperation of 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.
