Abstract
The utility model belongs to the electric power field, concretely relates to open dynamic relay. Including the shell, be equipped with two stationary contacts on the shell, be first stationary contact and second stationary contact respectively, two stationary contacts belows are equipped with the sheetmetal, and the sheetmetal both ends correspond with two stationary contacts and set up first movable contact and second movable contact, swing joint connecting rod in the middle of the sheetmetal, the sheetmetal below is equipped with armature, armature and connecting rod swing joint, on the shell was all fixed at the both ends of connecting rod, the connecting rod outer lane set up the spring, and open dynamic relay inside still is equipped with the coil. The utility model discloses simple structure, it is practical convenient, adopt low current starting heavy current, starting switch's frequent damage is avoided to the protection motor.
Description
Technical field
The utility model belongs to power domain, is specifically related to a kind of starting relay.
Background technology
Relay is a kind of electronic control device, is usually applied in automatic control circuit, plays the effects such as automatic adjustment, safeguard protection, change-over circuit in circuit.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of starting relay, and structure is simple, practical and convenient, adopts low current to start big current, and protection motor, avoids the frequent breakage of starting switch.
Starting relay described in the utility model, comprise shell, shell is provided with two fixed contacts, is respectively the first fixed contact and the second fixed contact, sheet metal is provided with below two fixed contacts, sheet metal two ends are corresponding with two fixed contacts arranges the first moving contact and the second moving contact, and sheet metal intermediate active connects connecting rod, is provided with armature below sheet metal, armature is flexibly connected with connecting rod, on the equal fixed housing in two ends of connecting rod, connecting rod outer ring arranges spring, and starting relay inside is also provided with coil.
Coil is positioned at spring side, and coil is fixed on enclosure.
Connecting rod is positioned at the centre of sheet metal, is also positioned at the centre of armature, and adopt prior art to connect, make sheet metal can be up and down along connecting rod, armature also can be up and down along connecting rod.During use, adopt prior art by coil two ends, first fixed contact and the second fixed contact are connected in circuit, opening power, connection circuit, very large by the electric current of coil, stronger magnetic field is produced in coil, armature is inhaled, armature promotes spring and moves upward, spring promotes sheet metal and moves upward, first moving contact and the first fixed contact are connected, second moving contact and the second fixed contact are connected, after motor enters normal operation, suddenly motor rated current is reduced to again by the electric current in coil, therefore the field weakening produced, first moving contact and the first fixed contact are disconnected, second moving contact and the second fixed contact disconnect, play winding no longer place in circuit, complete a subnormal startup.
In sum, the utility model has the following advantages:
The utility model structure is simple, practical and convenient, adopts low current to start big current, and protection motor, avoids the frequent breakage of starting switch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-shell, 2-first fixed contact, 3-second fixed contact, 4-sheet metal, 5-first moving contact, 6-second moving contact, 7-connecting rod, 8-armature, 9-spring, 10-coil.
Embodiment
Below in conjunction with embodiment, the utility model is described further.
Embodiment
A kind of starting relay, as shown in Figure 1, comprise shell 1, shell 1 is provided with two fixed contacts, be respectively the first fixed contact 2 and the second fixed contact 3, sheet metal 4 is provided with below two fixed contacts, sheet metal 4 two ends are corresponding with two fixed contacts arranges the first moving contact 5 and the second moving contact 6, sheet metal 4 intermediate active connects connecting rod 7, be provided with armature 8 below sheet metal 4, armature 8 is flexibly connected with connecting rod 7, on the equal fixed housing 1 in two ends of connecting rod 7, connecting rod 7 outer ring arranges spring 9, and starting relay inside is also provided with coil 10.
During use, adopt prior art by coil 10 two ends, first fixed contact 2 and the second fixed contact 3 are connected in circuit, opening power, connection circuit, very large by the electric current of coil 10, stronger magnetic field is produced in coil 10, armature 8 is dynamic by suction, armature 8 promotes spring 9 and moves upward, spring 9 promotes sheet metal 4 and moves upward, first moving contact 5 and the first fixed contact 2 are connected, second moving contact 6 and the second fixed contact 3 are connected, after motor enters normal operation, suddenly motor rated current is reduced to again by the electric current in coil 10, therefore the field weakening produced, first moving contact 5 and the first fixed contact 2 are disconnected, second moving contact 6 and the second fixed contact 3 disconnect, play winding no longer place in circuit, complete a subnormal startup.
