The motor wiring device with overheat-protecting capacity not only can play the function of the common junction device, but also can automatically break power when the electric motor generates heat by accident. The motor wiring device with overheat-protecting capacity can be directly installed on the electric motor. The motor wiring device with overheat-protecting capacity is comparatively economical and is a junction device which has over temperature protection ability. The utility model has the advantages of convenient maintenance and use, simple structure and high reliability.
Description
The utility model relates to a kind of motor wiring device, is suitable for a kind of protection termination that prevents that motor from damaging because of the heating of reasons such as brownout or overload especially.
General motor wiring device only plays the effect of connection, can't prevent that motor from hindering for some reason and cause that heating damages.And those motor protecting devices, structure is often complicated, thus as increasing an additional protection means, cost is improved, and inconvenient owing to installing, so very inapplicable to the motor in the machineries that much often will move.
The purpose of this utility model provides a kind of motor wiring device with overtemperature protection ability, and it can play the effect of common termination, can cut off the electricity supply automatically at motor adstante febre for some reason again.
The utility model is achieved in that in a termination that includes wiring pile, housing, a bimetal leaf is arranged, its end inserts in the motor field frame, mechanical transmission mechanism with hand and bimetal leaf control, drive contact chip rotation by this mechanical transmission mechanism, make contact chip closed mutually with the power supply wiring stake or separate with the motor wiring stake.This mechanical transmission mechanism can be made up of a rotating shaft swivel plate that drives and the hook-type plate that has hook portion.Under the motor operating state, a ledge is arranged on the free end of swivel plate, interlock with the hook portion of hook-type plate.This mechanical transmission mechanism also can be made up of the swivel plate that rotating shaft drives, and directly controls swivel plate with hand and bimetal leaf, makes the contact chip that is fixed on the swivel plate can make motor with the power supply closure or separate.
The utility model versatility is stronger, 7 kilowatts of of a of any type motor of applicable 1 to kind of specification.Cause is directly installed on the motor, thus use, easy to maintenance, and simple in structure, reliable operation, and can replace former terminal box, be a kind of both economical termination with overtemperature protection ability.
Utilize the example shown in the accompanying drawing, the utility model is further described.
Fig. 1 is the cutaway view of motor wiring device when closure.
Fig. 2 is the cutaway view of motor wiring device when separating.
Fig. 3 is an A-A cutaway view among Fig. 1.
Fig. 4 is the cutaway view of another embodiment clipped internal structure of motor wiring device.
Fig. 1, Fig. 2, Fig. 3 are a kind of embodiment of the present utility model.In this motor wiring device, have in the housing (1) between power supply wiring stake (2) and the motor stake (4) insulation board (3) is arranged, an end of bimetal leaf (14) inserts in the motor field frame.Swivel plate (7) that is driven by rotating shaft (8) and the hook-type plate (12) that is contained in rotating shaft (11) are formed mechanical transmission mechanism.A torsionspring (9) and torsionspring (10) respectively are housed in rotating shaft (8) and the rotating shaft (11).Contact chip (6) is fixed on the swivel plate (7), and swivel plate (7) can be made with insulating material, also can be between contact chip (6) and swivel plate (7) insulation board of liner, after preventing power connection, make rotating shaft charged.During use, the turn-knob in the rotating shaft that turns clockwise (8) also rotates the swivel plate (7) and the contact chip (6) that are fixed in the rotating shaft (8) thereupon.The free end of swivel plate (7) has a ledge (13), and it promotes hook-type plate (12) rotation, and makes the free end of hook-type plate (12) promote bimetal leaf (14) bending left.When the free end of hook-type plate (12) forwards bimetal leaf (14) upper end to, because the elastic reset of bimetal leaf (14) withstands hook-type plate (12) free end.At this moment the ledge (13) of swivel plate (7) is fastened by the hook portion of hook-type plate (12), and swivel plate (7) can not be circled round.Owing between contact chip (6) and the swivel plate (7) stage clip (15) is housed, make contact chip (6) power supply wiring stake (2) and motor wiring stake (4) close proximity, motor is promptly opened operation.Motor is adstante febre for some reason, make bimetal leaf (14) distortion crooked left, lose the support of bimetal leaf (14) with the free end that causes hook-type plate (12), effect because of torsion spring (10), make hook-type plate (7) to being rotated counterclockwise, the ledge (13) of its hook-type position and swivel plate (7) breaks off relations, because the effect of torsion spring (9) makes swivel plate (7) drive contact chip (6) and is rotated counterclockwise.Like this, power supply wiring stake (2) and motor wiring stake (4) are separated, and motor is promptly out of service.
Fig. 4 is another embodiment of the anti-overheated motor wiring device of the utility model.Housing, power supply wiring stake, motor wiring stake and the insulation board in the middle of them have been omitted among the figure.The mechanical transmission mechanism of this termination is made up of the swivel plate (7) that rotating shaft (8) drives.Torsionspring (9) is housed in the rotating shaft, and contact chip (6) is contained on the swivel plate (7), and adorns stage clip (15) in the middle of them.Swivel plate (7) can be made by insulating material, and perhaps insulation board of liner between swivel plate (7) and contact chip (6) is in case rotating shaft (8) is charged.During use, make rotating shaft (8) driven rotary plate (7) and contact chip (6) to turning clockwise, directly promote bimetal leaf (14) bending by the free end of swivel plate (7) with turn-knob.When the free end of swivel plate (7) turns to bimetal leaf (14) upper end, bimetal leaf (14) elastic reset, the free end of swivel plate (7) is withstood by bimetal leaf (14), at this moment contact chip (6) since the effect of stage clip (15) stake is connected with motor wiring with the power supply wiring stake, motor is promptly opened operation.In like manner, when motor adstante febre for some reason, bimetal leaf (14) heated bending, the free end of swivel plate (7) lose bimetal leaf (14) and support.Because the effect of torsion spring (15) makes contact chip (6) rotate to the inverse time meter with swivel plate (7).At this moment, motor wiring stake and power supply wiring stake are separated, and motor is promptly out of service.
