Description
Technical field
The utility model relates to a kind of automobile sensor, relates to a kind of throttle position sensor specifically.
Background technique
Environmental protection recently becomes the pith of government work, and when becoming the thing of the common concern in the world along with environmental protection at present, the Chinese government has taked actual action at automobile, releases the policy of a series of emission standards.The automobile of making energy-saving and emission-reduction is we automobile people's a great mission, because throttle position sensor has very important significance to energy-saving and emission-reduction, at present a lot of domestic a lot of automobile factorys select the commercial city E-Gas and this approach of electronic throttle to realize energy-saving and emission-reduction.We find that most of throttle position sensor operating life under rugged environment is short but make a general survey of outside the gateway of a country market, perhaps part user vehicle that automobile circuit is ignorant of is when cleaning automobile, allow throttle position sensor advance water because of carelessness, therefore this sensor is easy to damage.Also having a kind of situation in addition is in the process of assembly sensor substrate, the situation that has jitter occurs, because soldering is adopted in being connected of throttle position sensor substrate and terminal at present mostly, this welding manner cost is low, though this meeting allows very firm that terminal fixedlys connected with substrate, opening circuit but often appears in circuit.Reason is the oval-shaped circuit attachment hole that substrate is connected with terminal, weld the time out of joint, this circuit attachment hole inwall has silver slurry layer, play electric action, but in the process of welding, can cause the silver slurry layer fusing, therefore breaking phenomena can occur, make the scrappage of sensor rise, cost increases.
Summary of the invention
The purpose of this utility model provides a kind of throttle position sensor, and this sensor signal is stable, good waterproof performance, long service life.
In order to achieve the above object, a kind of throttle position sensor of the utility model, comprise shell, the end cap that links to each other with shell, be provided with substrate in the enclosure, substrate is provided with one group of resistance body that is electrically connected with ECU, be provided with brush carriage near the substrate, brush carriage is connected with throttle plate pin and rotation thereupon, on brush carriage, be provided with brush, one end of brush is connected with brush carriage, the other end contacts with resistance body, described substrate is connected with the terminal solder joint by the chip circuit attachment hole with resistance body, all be provided with at least one anti-via that opens circuit around each described resistance body, the inwall of the described anti-via that opens circuit is provided with the silver slurry layer that is connected with described chip circuit attachment hole silver slurry layer on every side.
Further, a sheathed seal ring in described throttle sensor rotating shaft.
Wherein, described shell is provided with an end cap fixed groove, and described end cap be located in this end cap fixed groove; The described end cap fixedly depression platform of cell wall and end cap periphery forms a glue-filling slot, is cast with casting glue in the described glue-filling slot; Described resistance body is carbon film or the layer high molecule conductive plastic that is coated in base surface.
The utility model makes it compared with prior art owing to adopted above-mentioned technological scheme, has following advantage and good effect:
Because the utility model is provided with the anti-via that opens circuit around each resistance body, when causing in the circuit attachment hole silver slurry layer fusing to come off because of welding process, silver slurry layer in the anti-via that opens circuit can substitute the effect that it plays connecting circuit, has reduced the scrappage of sensor to a great extent; Seal ring and end cap casting glue on every side set in the rotating shaft of moral door sensor can prevent that well sealing enters sensor, have prolonged its working life effectively.
