Description

A kind of spring contact fuel level sensor

Technical field

The utility model relates to a kind of automobile sensor more particularly to a kind of spring contact fuel level sensors.

Background technique

Fuel level sensor is generally fixed on automobile auxiliary fuel tank shell, work of the float on fuel level sensor in oil liquid buoyancy Float up and down under with the height of oil level, the floating up and down of float drives float swing arm to swing, float swing arm swing so that Resistance value in sliding variable resistance circuit changes, and is then converted into electric signal feedback to automobile oil gauge and shows fuel oil inventory information. The spring contact of the prior art is easily deformed using reed structure, reed, and reed installation site is not allowed to be fixed easily.In the presence of Resistance value is easy to appear the unstable disadvantage of breakpoint, oil level.

Utility model content

The purpose of this utility model is exactly to overcome the deficiencies of the prior art and provide a kind of resistance value to be less prone to breakpoint, oil level Stable spring contact fuel level sensor.

To achieve the goals above, the technical solution of the utility model is such that a kind of spring contact oil level passes Sensor, including float swing arm, oscillating arm bracket, guide, resistance plate rack, resistor disc, contact, the resistor disc are fixed on resistance On plate rack, the described guide indentation resistance plate rack fix connection, the oscillating arm bracket and the float swing arm and The guide does axial restraint connection, radially movable connection, and the contact end of the oscillating arm bracket is equipped with spring, the bullet Spring pushes down the contact, is in close contact the contact and the resistor disc.

The beneficial effects of the utility model are: the spring contact of the fuel level sensor of the utility model is using spring knot Structure only needs adjustment spring force value i.e. and can guarantee that contact contacts closely with resistor disc, avoids resistance value breakpoint defect.Also there is body simultaneously Product is small, structure is simple, install convenient, uses reliable, the feature of service life length.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples:

As shown in Figure 1, a kind of spring contact fuel level sensor, including float swing arm 1, oscillating arm bracket 2, guide 3, resistor disc Bracket 4, resistor disc 5, contact 7, the resistor disc 5 are fixed on resistance plate rack 4, and the guide 3 is pressed into resistor disc branch Frame 4 fix connection, the oscillating arm bracket 2 and the float swing arm 1 and the guide 3 do axial restraint connect, diameter To flexible connection, the contact end of the oscillating arm bracket 2 is equipped with spring 6, and the spring 6 pushes down the contact 7, makes described Contact 7 and the resistor disc 5 be in close contact.

The head of the contact 7 presses silver contact, so that electric conductivity is more excellent.
