Description
Technical field
the utility model relates to a kind of nut machine termination, the nut machine termination of particularly a kind of auto polarity switching.
Background technology
existing field vehicle with car nut attaching/detaching apparatus, be generally power taking from storage battery, the motor for nut attaching/detaching apparatus uses.But the direct current exported due to storage battery exists dividing of both positive and negative polarity, need during power taking to confirm whether both positive and negative polarity connects correctly, and during power taking, wiring is more inconvenient; When particularly visibility is lower, power taking wiring inconvenience and easy both positive and negative polarity wrong, cause burn-down of electric motor, fail safe is lower.Therefore, existing field vehicle with there is the problem that power taking wiring is inconvenient and fail safe is lower during the attaching/detaching apparatus power taking of car nut.
Utility model content
the purpose of this utility model is, provides the nut machine termination that a kind of auto polarity switches.Wiring when the utility model can not only facilitate power taking, also has the advantage that fail safe is high.
the technical solution of the utility model: the nut machine termination that auto polarity switches, comprises power access end A and power access end B, is connected with relay and the diode of series connection mutually between power access end A and power access end B; Relay is provided with commutator A and commutator B, and the stiff end of commutator A and the stiff end of commutator B are fixedly connected with cathode output end and cathode output end respectively; The mobile terminal of described commutator A is connected with power access end A or power access end B, and the mobile terminal of commutator B is connected with power access end B or power access end A; Described commutator A and commutator B links.
in the nut machine termination that aforesaid auto polarity switches, described power access end A is connected with contact A parallel with one another and contact A ' by wire, power access end B is connected with contact B parallel with one another and contact B ' by wire; The mobile terminal of described commutator A is connected with contact A or contact B, and the mobile terminal of commutator B is connected with contact B ' or contact A '.
compared with prior art, the utility model devises the nut machine termination that a kind of auto polarity switches, be connected the both positive and negative polarity of storage battery with power access end B by power access end A, the one-way flow realizing electric current by arranging diode carrys out control relay work, controlled the link position of commutator A and commutator B by the relay arranged, export finally by cathode output end and cathode output end; When power access end A connects the positive pole of storage battery, power access end B connects the negative pole of storage battery, now diode not conducting, relay quits work, and commutator A connects power access end A, and commutator B connects power access end B, namely cathode output end is positive pole, and cathode output end is negative pole; When power access end A connects the negative pole of storage battery, power access end B connects the positive pole of storage battery, now diode current flow, relay is started working, and commutator A connects power access end B, and commutator B connects power access end A, namely cathode output end is positive pole, and cathode output end is negative pole; Thus achieve automatically polarity and switch, wiring when greatly facilitating power taking, can also prevent the motor damage because wiring error causes, improve fail safe.Therefore, wiring when the utility model can not only facilitate power taking, also has the advantage that fail safe is high.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-power access end A, 2-power access end B, 3-relay, 4-diode, 5-commutator A, 6-commutator B, 7-cathode output end, 8-cathode output end, 9-contact A, 10-contact A ', 11-contact B, 12-contact B '.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.The nut machine termination that auto polarity switches, forms as shown in Figure 1, comprises power access end A1 and power access end B2, is connected with relay 3 and the diode 4 of series connection mutually between power access end A1 and power access end B2; Relay 3 is provided with commutator A5 and commutator B6, and the stiff end of commutator A5 and the stiff end of commutator B6 are fixedly connected with cathode output end 7 and cathode output end 8 respectively; The mobile terminal of described commutator A5 is connected with power access end A1 or power access end B2, and the mobile terminal of commutator B6 is connected with power access end B2 or power access end A1.
described power access end A1 is connected with contact A9 parallel with one another and contact A ' 10 by wire, power access end B2 is connected with contact B11 parallel with one another and contact B ' 12 by wire; The mobile terminal of described commutator A5 is connected with contact A9 or contact B11, and the mobile terminal of commutator B6 is connected with contact B ' 12 or contact A ' 10.
during use, be connected by power access end A1 with power access end B2 with the positive and negative end of storage battery, make cathode output end 7 be fixedly connected with the electrode input end of motor, cathode output end 8 is fixedly connected with the negative input of motor.When power access end A1 connects the positive pole of storage battery, power access end B2 connects the negative pole of storage battery, now diode 4 not conducting, relay 3 quits work, commutator A5 connects power access end A1 by contact A9, and commutator B6 connects power access end B by contact B ' 12, and namely cathode output end 7 is positive pole, cathode output end 8 is negative pole, and wiring is correct; When power access end A1 connects the negative pole of storage battery, power access end B2 connects the positive pole of storage battery, now diode 4 conducting, relay 3 is started working, commutator A5 connects power access end B2 by contact B11, and commutator B6 connects power access end A1 by contact A ' 10, and namely cathode output end is positive pole, cathode output end is negative pole, and wiring is correct; Thus achieve automatically polarity and switch, wiring when greatly facilitating power taking, can also prevent the motor damage because wiring error causes, improve fail safe.
