Abstract
The utility model discloses an ESP acceleration sensor box which belongs to the field of automotive electronics application and comprises a casing, a cover board and a circuit board, wherein, a transverse/longitudinal acceleration sensor, a yaw rate sensor, a dedicated chip and various relevant electronic components are welded on the circuit board; a circle of groove which can be filled with sealant is formed on junction surface of the casing, the inner walls of the casing are sprayed with metal shield paint, and the casing is buckled with two asymmetrical joining holes at the joint of the cover board; and a plurality of plug pins are embedded in the interface, wherein, ends of the plug pins are in plug connection with an external circuit, and the other ends of the plug pins are welded with the internal circuit. The utility model is characterized in that a protective shielding layer that is effectively resistant to electromagnetic interference is built and an improvement on the prior structure is adopted for protecting the sensor chip and the peripheral circuit against the interference by an external signal source, thereby effectively solving the problems that the box runs an increased risk of being to subject to reverse assembly during assembly, and insufficient sealing leads the cover board to absorb water and become damp, and greatly improving the reliability of the product.
Description
Technical field
The utility model belongs to the automobile electronics application, is specifically related to a kind of ESP acceleration transducer box.
Background technology
ESP (Electronic Stability Program) means " vehicle electronic stability system ", is a kind of brake system that prevents vehicle slip under the emergency running condition, and its topmost characteristics are exactly its initiative, can accomplish to prevent trouble before it happens.The ESP system can reduce the danger of defective steering stabilizer, thus the generation of reduction accident.
The ESP acceleration transducer is one and adopts two kinds of special chips of horizontal/longitudinal acceleration sensor and yaw-rate sensor to reach the inertial sensor combination of being made up of interlock circuit, is one of core component of ESP automobile electronic stabilization system.
The ESP acceleration transducer is an electronic product, and box body structure is simple relatively, mainly is made up of housing, cover plate and printed circuit board etc.The contour structures of housing is limited by often the automobile installation position or design need be satisfied the installation requirement of main engine plants, and the inner chamber of housing need guarantee pack into printed circuit board and cover plate; The retrieval of the international and domestic interrelated data of tool, existing ESP acceleration transducer box has polytype, the box body structure of usefulness usually, the printed circuit plate level is placed in the housing, internal circuit with patch pin employing flexible printed circuit and be connected; Cover plate adopts inlays the Copper Foil shielding; Mistake proofing is installed adopts the single hole location.And inside and outside circuit connecting mode often is difficult to accomplish problems such as the sensor that anti-electromagnetic interference (EMI) and anti-loading error cause absorbs water, makes moist, sensitivity inefficacy.
The utility model content
The purpose of this utility model is the problem that connects, prevents loading error and waterproof for the anti-electromagnetic interference (EMI) that solves ESP acceleration transducer box, inside and outside circuit.
The utility model proposes a kind of novel ESP acceleration transducer box, form by housing 1, cover plate 2, circuit board 11, horizontal/longitudinal acceleration sensor and yaw-rate sensor special chip and relevant all kinds of electronic devices and components has been welded on the circuit board 11, according to the direction difference of special chip axis of operation, but circuit board 11 levels or vertical fixing are installed on housing 1 inner chamber or the cover plate 2; Described housing 1 docks with cover plate 2, and the interface of housing 1 has the groove 4 that can insert fluid sealant a week, and inner-wall spraying metallic shield lacquer is with two asymmetric butt hole snappings of cover plate 2 joints; Shielding lacquer in cover plate 2 inside surface spray metals patches pin and adopts the embedding and injection molding method to be fixed on inside, is inlaid with several in the plug receptacle and patches pin, and an end patches with external circuit and connects, and the other end connects with the internal circuit welding.
The utility model has taked the inwall at housing, the inside surface of cover plate to set up effectively anti-electromagnetic interference shield protective seam; be not subjected to the interference of outside source with protection sensor chip and peripheral circuit part; adopt the various difform pins that patch; be embedded in cover plate 2 parts single injection-molded.Effectively solving anti-dress appears in the assembling process easily and at cover plate because the improper suction that causes of sealing, the problem of making moist, product reliability is greatly improved.
