    PURPOSE: Structure of an accelerator position sensor is provided to prevent wear of a circuit pattern and a terminal by spreading fluorine on the circuit pattern and the terminal, and to improve performance of an engine by preventing engine stall with restricting contact failure of the accelerator position sensor. CONSTITUTION: An accelerator position sensor comprises a housing, and a printed circuit board(10) installed in the housing. Plural circuit patterns(11) are printed on the printed circuit board, and plural terminals(12) are connected to the circuit patterns to convert force in stepping on an accelerator pedal into voltage to control output of an engine. Fluorine is spread on the circuit patterns and the terminals to prevent wear and rust and resist heat. The accelerator position sensor transmits a data signal accurately by restricting the terminals and the circuit patterns from coming off with spreading fluorine on the circuit patterns and the terminals.

    Accel Position Sensor Structure {STRUCTURE FOR ACCELERATOR POSITION SENSOR}
    [9] The present invention relates to an accelerator position sensor structure, and more particularly, to an accelerator position sensor structure in which the structure is improved to prevent contact failure.
    [10] The accelerator position sensor is used to convert the amount of pedaling of the accelerator pedal into a voltage and input it to a computer to control the output of the engine to prevent slippage of the tire on the slippery road and to improve steering performance during turning.
    [11] By the way, there are problems such as relief of the engine speed (rpm) and start-up of the engine speed (rpm) in the stopped state of the vehicle, and deterioration of the reliability of the vehicle due to acceleration and drunkenness while driving.
    [12] There are many factors that cause this problem, but one of them is caused by a poor contact of the accelerator position sensor.
    [13] The reason for the poor contact of the accelerator position sensor is that a pattern or a terminal of a printed circuit board (PCB) provided in the accelerator position sensor is lifted due to long-term use or vibration of the vehicle. .
    [14] SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an accelerator position sensor structure which improves vehicle reliability by preventing floating of patterns or terminals of a printed circuit board.

    [15] Accel position sensor structure of the present invention for achieving the above object is provided in the housing, the housing, a plurality of circuit patterns are printed, a plurality of terminals connected to the circuit pattern is provided with a printed circuit board In the accelerator position sensor structure which converts the amount of stepping of the accelerator pedal into a voltage to control the output of the engine, fluorine is coated on the circuit pattern and the terminal to prevent wear of the circuit pattern and the terminal. It features.
    [16] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    [17] FIG. 1 is a schematic view showing a main configuration of an accelerator position sensor structure according to the present invention, and FIGS. 2A and 2B are cross-sectional views respectively shown in FIG. 1.
    [18] Referring to the drawings, the accelerator position sensor structure according to the present invention includes a housing (not shown) and a plurality of circuit patterns 11 printed on the housing, and connected to the circuit patterns 11. A printed circuit board 10 having a terminal 12 is provided to convert the amount of stepping of the accelerator pedal into a voltage to control the output of the engine.
    [19] Particularly, in the accelerator position sensor structure, the terminal 12 includes 5 pins of an idle switch, a power supply, an accelerator position sensor signal, an signal ground, and an idle ground. do.
    [20] By separating the ground from such a signal configuration, the reliability of noise is improved, and the accelerator position sensor signal that is varied is detected by an ECU (engine controller), and the accelerator position sensor signal is processed by a microcomputer.
    [21] And as a feature of the invention, fluorine (F) 20 is applied over the circuit pattern 11 and the terminal 12 to prevent wear of the circuit pattern 11 and the terminal 12.
    [22] Referring to the operation of the accelerator position sensor structure according to the present invention having the configuration as described above are as follows.
    [23] Referring back to the drawings, the accelerator position sensor structure according to the present invention, the fluorine 20 coated on the circuit pattern 11 and the terminal 12 is adhered to the slide surface of all the machines to maintain the precision and long life It is guaranteed and can be used continuously without failure in the range of about -220 ℃ ~ 232 ℃. This fluorine 20 has excellent chemical resistance and corrosion resistance, and has very high stability.
    [24] In particular, it is used as a polymer material of fluorocarbon polymer, fluorine 20, which is an inert element and resistant to abrasion, is applied to the printed circuit board 10 of the accelerator position sensor to prevent wear.
    [25] And this fluorocarbon polymer is as strong as water and oil and has the property to splatter any liquid. Since carbon atoms are strongly bound to other carbon atoms, it is almost impossible to break the bond and bond them with atoms of other materials. Do.
    [26] Due to such an exclusive property, the fluorocarbon polymer is not rusted or burned, is completely harmless and is not received at all from other materials. Thus, the fluorocarbon polymer does not attach to anything because it is not integrally associated with other molecules. That is, since the surface is very slippery and very strong against heat, it can be applied to the printed circuit board 10 in the accelerator position sensor because it can be prevented from being pressed.
    [27] Therefore, as described above, when the fluorine 20 is applied to the circuit pattern 11 and the terminal 12 of the printed circuit board 10, it is possible to prevent the lifting of these circuit patterns 11 and the terminal 12. This can enhance contactability and accurately transmit data signals from the accelerator position sensor.
    [28] As described above, the accelerator position sensor structure according to the present invention has the following effects.
    [29] It is possible to prevent a poor contact of the accelerator position sensor to improve the performance of the engine, it is possible to prevent the relief of the engine speed (rpm), and in particular to improve the idle rpm.
    [30] Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
