Description
Technical field:
This utility model relates to the new-energy automobile of a kind of band noise trap.
Background technology:
Along with developing rapidly of new-energy automobile, current car load is more and more higher for the stability requirement of system.Increase at present on new energy vehicle and have substantial amounts of high pressure equipment, between these high pressure equipmentes, have various control and the low voltage wiring harness that communicates.Therefore, the high-tension circuit interference to these low-voltage signals can be there is, car load time serious, can be made normally to work.
Summary of the invention:
The purpose of this utility model is to provide the new-energy automobile of a kind of band noise trap, can effectively suppress the interference to other control panel of the automobile inner high voltage equipment, ensures that automobile can normally work, improves stability.
The purpose of this utility model is achieved by following technical proposals.
A kind of new-energy automobile of band noise trap, including the body of a motor car electrically connected with the earth, it is arranged on the control panel inside body of a motor car, it is characterized in that: described noise trap includes three terminal capacitor suppressor, electrical control equipment is with metal shell, one pin electrical connection body of a motor car of three terminal capacitor suppressor, two pins of remaining of three terminal capacitor suppressor are connected electrically on the metal shell of control panel.
Control panel described above is high voltage electric equipment.
Control panel described above is low voltage equipment.
Three terminal capacitor suppressor described above includes electric capacity C1, electric capacity C2 and electric capacity C3, is together in parallel with electric capacity C3 and draws the first pin and the 3rd pin at place in parallel, draw the second pin between electric capacity C1 and electric capacity C2 after electric capacity C1 and electric capacity C2 series connection.
Control panel described above is multiple stage, and every control panel one three terminal capacitor suppressor of configuration is anti-interference.
Body of a motor car described above is to comprise vehicle frame.
Electric capacity C1, electric capacity C2 and the parameter of electric capacity C3 described above are the same or different.
Optional pin electrical connection body of a motor car in the first pin, the second pin and the 3rd pin described above, other two pin is connected electrically on the metal shell of control panel.
This utility model compared with prior art, has the effect that
1) described electrical control equipment is with metal shell, one pin electrical connection body of a motor car of three terminal capacitor suppressor, two pins of remaining of three terminal capacitor suppressor are connected electrically on the metal shell of control panel, the effectively suppression automobile inner high voltage equipment interference to other control panel, ensure that automobile can normally work, improve stability；
Three terminal capacitor suppressor includes electric capacity C1, electric capacity C2 and electric capacity C3, it is together in parallel with electric capacity C3 after electric capacity C1 and electric capacity C2 series connection and draws the first pin and the 3rd pin at place in parallel, the second pin is drawn between electric capacity C1 and electric capacity C2, electric capacity C1, electric capacity C2 are the same or different with the parameter of electric capacity C3, simple in construction, anti-jamming effectiveness is good；
2) control panel is multiple stage, and every control panel one three terminal capacitor suppressor of configuration is anti-interference, and so, each control panel carries out anti-interference independently of each other, reduces reciprocal influence.
3) optional pin electrical connection body of a motor car in the first pin, the second pin and the 3rd pin, other two pin is connected electrically on the metal shell of control panel.I.e. three terminal capacitor suppressor can arbitrarily select a pin electrical connection body of a motor car, and two pins of remaining of three terminal capacitor suppressor are connected electrically on the metal shell of control panel, so, conveniently connect, it is to avoid wrong line.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the circuit diagram of three terminal capacitor suppressor of the present utility model.
Detailed description of the invention:
Below by specific embodiment and combine accompanying drawing this utility model is described in further detail.
Embodiment one: as shown in Figure 1 to Figure 2, the new-energy automobile of this utility model a kind of band noise trap, including the body of a motor car electrically connected with the earth, it is arranged on the control panel inside body of a motor car, described noise trap includes three terminal capacitor suppressor, electrical control equipment is with metal shell, one pin electrical connection body of a motor car of three terminal capacitor suppressor, two pins of remaining of three terminal capacitor suppressor are connected electrically on the metal shell of control panel.Described control panel can be high voltage electric equipment.Described control panel can also be low voltage equipment, described three terminal capacitor suppressor includes electric capacity C1, electric capacity C2 and electric capacity C3, it is together in parallel with electric capacity C3 after electric capacity C1 and electric capacity C2 series connection and draws the first pin and the 3rd pin at place in parallel, between electric capacity C1 and electric capacity C2, drawing the second pin.Described control panel is multiple stage, and every control panel one three terminal capacitor suppressor of configuration is anti-interference.Body of a motor car of the present utility model comprises vehicle frame.
