Abstract
The utility model discloses a wear-resistant and oil-resistant liquid level sensor, which relates to the technical field of the sensor. A resistor is arranged on a framework. The framework is connected with a reed through a pin, a reed support and a spring. The liquid level sensor is characterized in that a gold-plated contact and a gold alloy contact are respectively riveted in a radial direction of the reed towards the resistor; the gold-plated contact is closer to the pin than the gold alloy contact; and the gold-plated contact consists of an alloy inner layer and a surface gold-plated layer. As two contacts are used between the reed and the resistor, and made from special materials, the wear-resistance and the corrosion-resistance of the sensor are improved, so that the electrical output performance of the sensor can be more stable.
Description
Technical field
The utility model relates to sensor technical field, especially liquid level sensor.
Background technology
Contact liquid level sensor of the prior art utilization can change resistance value with respect to the contact on the resistor disc rotary type reed, realizes the output of transducing signal.Because the single contact of existing employing welding is good inadequately aspect wear-resistant and oil resistant corrosion, particularly in the various oil that contain additive impurity.The contact is easy to be corroded in fuel oil, causes loose contact, and the signal stabilization of output is relatively poor, and the automobile oil gauge indication is inaccurate.
The utility model content
The utility model purpose is to design and a kind ofly can overcomes that prior art defective, wearing quality are good, the good wear-resistant oil-proof liquid level sensor of signal stabilization of transmission.
The utility model comprises skeleton, resistor disc is set on skeleton, be connected reed by pin with reed support and spring on the skeleton, be characterized in upwards riveting a gold plated contact and a billon contact respectively towards a footpath of the described reed of resistor disc, described gold plated contact approaches pin than the billon contact, and described gold plated contact is made up of alloy internal layer and surface gold-plating layer.
The utility model adopts two contacts between reed and resistor disc, and adopts special material to make, and can improve the anti-wear performance and the decay resistance of product, makes the electrical property output of sensor more stable.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cut-away view.
Embodiment
As shown in Figure 1, on skeleton 1, fixedly install resistor disc 3, also be connected reed 4 on the skeleton 1 by pin 7 and reed support 2 and spring 6.Electric wire 8 is fixed on a side of skeleton 1, and its end links to each other with resistor disc 3 by joint.
Upwards riveting a gold plated contact 5-1 and a billon contact 5-2 respectively towards a footpath of the reed 4 of resistor disc 3, gold plated contact 5-1 approaches pin 7 than billon contact 5-2, and the gold-plated 5-2 of touching point is made up of alloy internal layer and surface gold-plating layer.
