Description
Technical field
The utility model relates to power battery fields, and in particular to a kind of high voltage connector.
Background technique
Battery pack high tension loop is usually to be controlled by high voltage connector in electric car, past in cutoff high circuit
Toward that can generate electric arc, current high voltage connector, which is usually utilized in spark chamber, installs magnet, stretches electric arc by magnetic field, simultaneously
It pours inert gas intracavitary and realizes fast arc extinction.
Since the high tension loop of battery pack is usually while having charging and discharging function, thus it is electric in cutoff high circuit
The draw direction of arc will appear variation, when electric arc stretching close to each other, it is likely that and cause electric arc to merge, improves arc extinguishing difficulty,
And then improve risk；Simultaneously because arc stiffness increases, the corrosion of contact is enhanced, can further shorten high voltage connector
Service life；In order to ensure the stability of high voltage connector, it has to make contact using more corrosion resistant conductive metal, in this way
The manufacturing cost of battery pack is improved indirectly.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of high voltage connector, and electric arc fusion can be effectively reduced
Generation, improve the reliability of high voltage connector.
The utility model provides a kind of high voltage connector, including pedestal and arc-extinguish chamber, and the arc-extinguish chamber is assemblied in described
On pedestal, the base exterior is provided with fixed device and coil interface, the chassis interior include coil, armature, iron core,
Movable contact spring and connecting rod, the coil are electrically connected with the coil interface, and the armature is fixed on the chassis interior, described
Movable contact spring is connect by the connecting rod with the iron core, and the coil is wrapped on the iron core, is arranged on the arc-extinguish chamber
There are stationary contact and magnet, the stationary contact is two, and the magnet is attached in the side of the arc-extinguish chamber, and the magnetic of the magnet
Field direction is filled with inert gas in the arc-extinguish chamber perpendicular to the moving direction of the movable contact spring, the movable contact spring and described
Stationary contact is high conductive metal material, and the line direction of the stationary contact is not parallel to the magnetic direction of the magnet,
The movable contact spring and the stationary contact cooperate, it is ensured that two stationary contacts realize electrical connection when contacting with each other.
A kind of high voltage connector provided by the utility model, two stationary contacts are arranged in and are not parallel to magnetic field of magnets direction
On direction, when electric arc stretches along magnetic direction and is close to each other, not in a plane due to electric arc, generation can not be merged more
Strong electric arc avoids risk caused by fusion electric arc, meanwhile, it, will not be intermittently to quiet because electric arc does not merge
Contact, movable contact spring generate deep-etching, the service life of high voltage connector are improved, in addition, being not required to when making stationary contact, movable contact spring
It selects more corrosion resistant conductive metal as material, thereby reduces the cost of battery pack.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model high voltage connector.
Fig. 2 is the top view of the utility model high voltage connector.
Wherein, 1 is pedestal, and 2 be arc-extinguish chamber, and 3 be stationary contact, and 4 be magnet, and 5 be fixed device, and 6 be coil interface, 7 ranks
Iron, 8 be coil, and 9 be iron core, 10 is movable contact spring, 11 is connecting rod.
Specific embodiment
More detailed description is done to the utility model below in conjunction with attached drawing.
Fig. 1, Fig. 2 are a kind of schematic diagram of specific embodiment of the utility model
As a kind of specific embodiment of the utility model, high voltage connector includes pedestal (1) and arc-extinguish chamber (2), arc extinguishing
Cover (2) is assemblied on pedestal (1), and fixed device (5) and coil interface (6) are provided with outside pedestal (1), and pedestal (1) is internal
It is provided with armature (7), coil (8), iron core (9), movable contact spring (10) and connecting rod (11), armature (7) is fixed in pedestal (1)
Portion, movable contact spring (10) are connect by connecting rod (11) with iron core (9), and coil (8) is wrapped on iron core (9).
As a kind of preferred embodiment of the utility model, movable contact spring (10) is in " Z " word structure.
Further, coil (8) is electrically connected with coil interface (6), the electrical connection of coil interface (6) outer low pressure circuit.
Further, stationary contact (3) totally two, the position of two stationary contacts (3) and two endpoints of movable contact spring (10) match
It closes, is assemblied on the upper surface of arc-extinguish chamber (2), two stationary contacts (3) are electrically connected with external high pressure circuit.
Further, magnet (4) is attached in the side of arc-extinguish chamber (2), and the magnetic direction of magnet (4) is perpendicular to movable contact spring
(10) moving direction, arc-extinguish chamber (2) is interior to be filled with inert gas.
As a kind of preferred embodiment of the utility model, movable contact spring (10) is made with stationary contact (3) of red copper.
The course of work of above-described embodiment is as follows:
When needing to connect battery pack high-tension circuit, outer low pressure route is connected, and coil generates magnetic field, in the work of electromagnetic force
Under, iron core attracts each other with armature, and then movable contact spring is promoted to move up, electrical connection movable contact spring (10) and stationary contact (3), connects outer
Portion's high-tension circuit.
