Description
Technical field
This utility model relates to high-voltage DC contactor correlative technology field, and specifically one is for New energy electric
HVDC vacuum contactor in coach air conditioner.
Background technology
The catalyst of automobile refers to utilize coil to flow through current induced magnetic field, makes contact closure, thus realizes effective
Power transmits.Conventional catalyst is by electromagnetic system (dynamic iron core, static iron core and solenoid), contact system and arc-control device group
Become.After the solenoid of catalyst is energized, the strongest magnetic field can be produced, make static iron core produce electromagnetic attracting force and move iron core, and
Drive contact action: contact closure；When the coil is de-energized, electromagnetic attraction disappears, and dynamic iron core discharges under the effect of release spring,
Contact is made to restore: contact disconnects.
Existing automobile high-voltage DC contactor has the shortcomings such as structure is complicated, volume is big, sealing is not enough.

In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of HVDC vacuum contactor in New energy electric coach air conditioner, has housing, it is characterised in that
Housing upper end is provided with positive pole input interface and positive pole output interface, is provided with power rail, moving contact and location shell in housing, dynamic
Contact also and has spacing in the lower end of positive pole output interface between positive pole output interface, be provided with coil, line in the shell of location
Snare is located at outside power rail, and the upper end of power rail is connected with the lower end of moving contact by connecting plate, and the top of moving contact is passed through
Connect sheet to be connected with the bottom of positive pole input interface, between positive pole input interface and housing, positive pole output interface and housing it
Between and positive pole input interface and positive pole output interface between be equipped with insulated enclosure locating ring and seal lid, seal lid be positioned at
The outside of insulated enclosure locating ring.
Further, the bottom of described enclosure interior has groove, and the bottom of power rail is placed in described groove, power
The upper end of bar protrudes from the upside of location shell.
Further, the outside of power rail is also arranged with back-moving spring, and the lower section of coil is located at by back-moving spring, back-moving spring
Lower end abuts with the bottom of housing.
This utility model has the advantages that
Have simple in construction, volume is little, the life-span is long, lightweight advantage, the EV series that its function and u s company produce
The EV series seal DC contactor that D.C. contactor, PANASONIC electrician produce is similar to, and can be widely applied to: dig up mine-drive
Move and control system, electric automobile, mobile excavating equipment, aviation mobile device, power supply backup system, hydrogen fuel cell drivetrain
System, boats and ships and underwater installation, the alternating current and direct current power switching device such as solar power plant, is the power supply of Large-scale Mobile equipment
The ideal chose in loop.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model high-voltage DC contactor；
Fig. 2 is the internal structure schematic diagram of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described, but protection domain of the present utility model not only office
It is limited to embodiment.
Shown in Fig. 1-Fig. 2, a kind of HVDC vacuum contactor in New energy electric coach air conditioner, have
Housing 12, housing 12 upper end is provided with positive pole input interface 8 and positive pole output interface 2, is provided with power rail 11, moves and touch in housing 12
3 and location shell 5.Moving contact 3 also and has spacing between positive pole output interface 2 in the lower end of positive pole output interface 2.Fixed
Position shell 5 is positioned at the lower position of enclosure interior, is provided with coil 6 in the shell of location, and it is outside that coil 6 is set in power rail 11, dynamic
The upper end of power bar 11 is connected with the lower end of moving contact 3 by connecting plate 13, and the top of moving contact 3 inputs with positive pole by connecting sheet
The bottom of interface 8 connects.Coil 6 is connected with coil power line 1.
Bottom within housing 12 has groove, and the bottom of power rail 11 is placed in described groove, power rail 11 upper
End protrudes from the upside of location shell 5.The outside of power rail 11 is also arranged with back-moving spring 7, and coil 6 is located at by back-moving spring 7
Lower section, the lower end of back-moving spring 7 abuts with the bottom of housing 12.
Between positive pole input interface 8 and housing 12, between positive pole output interface 2 and housing 12 and positive pole input interface
It is equipped with insulated enclosure locating ring 10 between 8 and positive pole output interface 2 and seals lid 9, sealing lid 9 and be positioned at insulated enclosure locating ring
The outside of 10.Housing cavity above the shell of location is vacuum chamber 4.
In its natural state, moving contact 3 does not contacts with positive pole output interface 2, and after coil electricity, power rail is at the action of a magnetic field
Under move upward, power rail drive moving contact 3 also move upward so that moving contact 3 contacts conducting with positive pole output interface 2.When
After coil blackout, magnetic field disappears, and power rail 11 moves downward under back-moving spring 7 acts on so that moving contact 3 connects with positive pole output
Mouthfuls 2 separated.
