CONNECTOR HAVING PORT FOR SETTING PARAMETER INTEGRATED CIRCUIT DEVICE OF HALL SENSOR MODULE}

The present invention relates to a Hall sensor module for detecting the inclination and the rotation direction, and more particularly, in response to the specification of the electronic system of the vehicle, the hall module in the modular state and the module connected to the system when setting the parameters of the hall sensor module A connector of a hall sensor module having a parameter setting port of an integrated circuit device for setting parameters of a sensor module.

As the automotive and electronics industries develop, automobiles are equipped with various electronic devices for driver safety and convenience.

These electronic devices have a connector for connecting with the electronic system of the vehicle or for interconnecting the electronic devices. One of these electronic devices automatically controls the headlight, such as the Auto Head Lamp Leveling System (AHLS) or the Adapted Front Lighting System (AFLS), which automatically adjusts the vehicle's headlights up, down, left and right according to the vehicle's forward and backward tilt or rotational direction. Regulation system. The headlight automatic control system includes a hall sensor module that detects the tilt and the rotation direction of the vehicle to automatically adjust the headlight according to the tilt and the rotation direction of the vehicle.

1 is a view showing the appearance of a general Hall sensor module.

Referring to FIG. 1, the hall sensor module includes a connector 10, a body housing 20, and a hall sensor module substrate 30.

The connector 10 is a portion that is connected to a vehicle electronic system such as a headlight automatic control system.

The main body housing 20 serves to surround and protect the hall sensor module substrate 30.

The connector 10 and the body housing 20 are integrally formed.

The hall sensor module substrate 30 includes electronic circuits including Hall ICs for detecting the front and rear tilt and the rotation direction of the vehicle.

2 and 3 are diagrams showing the electronic configuration of the Hall sensor module in the general Hall IC setting.

2 and 3, the hall sensor module includes a connector 10, a regulator 31, an MCU 32, and a hall IC 33.

The connector 10 is a male electrical connector, which transmits and receives data to and from a power pin, a ground pin (GND), and a vehicle system for receiving power (Vcc) from a 12V or 24V vehicle battery to correspond to a female electrical connector of a vehicle electronic system. Data transmission and reception pins (Tx, Rx) and the like.

The regulator 20 receives the vehicle power Vcc connected to the power pin Vcc and the ground pin GND of the connector 10 and receives the input vehicle power Vcc, and converts the driving power VDD required in the hall sensor module. To print.

The MCU 32 operates by receiving the driving power VDD output from the regulator 20 and controls the overall operation of the hall sensor module.

The Hall IC 33 includes a storage unit for storing a plurality of parameter values for controlling an operation, and operates by receiving a driving power supply VDD output from the regulator 20 and based on the parameter values. Detects the vehicle's front / rear tilt and rotation direction and outputs it. As such, the hall IC 33 must set the parameter value in order to output the requested data. Normally, the hall IC 33 needs a writing power higher than the driving power supply VDD to set a parameter value. In general, the writing power supply of the Hall IC 33 is 7.5V.

Therefore, in order to set the parameters of the hall IC 33, the lighting power and the parameter to be set, that is, the setting data must be provided to the hall IC 33. In order to provide the writing power to the Hall IC 33, the writing power line of the writing power supply unit 100 should be connected to a node input from the regulator 31 to the driving power supply terminal VDD of the Hall IC 33 in FIG. 2. And, the ground line of the lighting power supply unit 100 should be connected to the ground node of the hall sensor module. The setting data line should be connected to the data output terminal OUT of the hall IC 33.

In this case, the writing power is higher than the driving power so that the power supply flows back to the regulator 31 and the MCU 32, thereby causing damage to peripheral circuits such as the regulator 31 and the MCU 32.

In order to improve such a problem, as shown in FIG. 2, the terminal has a terminal for receiving driving power from the regulator 31 and a terminal for receiving writing power from the writing power supply unit 100 in front of the hall IC 33. Hall sensor module has been developed that includes a switch unit 34 for switching depending on the input whether the drive power and the lighting power selectively output to the Hall IC (33). In this case, the writing power supply line should be connected to the switch section 34 and the drive power supply terminal (VDD) node of the hall IC 33.

2 and 3, in order to facilitate maintenance by changing a parameter of the hall sensor module, the connector 10 further includes male pins to which the writing power line, the ground line, and the setting data receiving line are connected. It is desirable to.

However, since the pins of the connector 10 must be configured to correspond to the pins of the female electrical connectors of the electronic system of the vehicle, there is a problem in that the male pins for parameter setting of the hall sensor module cannot be configured in the connector 10.

Due to this problem, the following three methods are used for parameter setting.

In the first method, the drawing pins connected to the corresponding nodes 101, 102, and 103 are connected to the hall sensor module in order to connect the writing power line, the ground line, and the data line of the writing power supply unit 100 to the hall sensor module board 30. It is a method of pre-soldering on the phase.

The second method is to remove the lines by temporarily soldering the lines directly to the node, setting the parameters, and then removing the soldering.

The last method is to remove only the Hall IC 33 from the substrate, change the parameters, and insert the same again into the substrate.

However, the above-described methods have a problem that it is cumbersome and time-consuming because the substrate must be separated to set parameters.

In addition, the aforementioned methods have a problem in that secondary failure may occur due to disassembly, recombination, or soldering.

Accordingly, an object of the present invention is to correspond to the standard of the electronic system of the vehicle, and the parameters of the integrated circuit device to set the parameters of the hall sensor module in the modular state and the module connected to the system when setting the parameters of the hall sensor module It is to provide a connector of a hall sensor module having a setting port.

The connector may further include a ground parameter setting port connected to the ground terminal of the hall IC.

The parameter setting ports are formed on a surface on which the plurality of male electrical contacts are formed.

The parameter setting ports are formed in a straight line on the outer surface of the connector.

Further comprising a latch portion in the downward direction at both ends of the straight line of the connector, the second body housing, the writing power supply line for supplying the writing power, the ground line and the setting data receiving line are respectively connected and the second body And a second connector including groove electrical contacts formed on a lower side of the housing, and fixing hooks formed at both ends of the second body housing to be hooked to the latch to be fixed to the connector. .

Therefore, the connector according to the present invention satisfies the specification of the electronic system of the vehicle, but does not need to separate the module board from the module each time the initial setting and change of parameters has a convenient effect on maintenance.

In addition, the present invention can change the parameters of the Hall sensor module even when the Hall sensor module is connected to the vehicle system, and thus the maintenance is convenient.

In addition, the connector of the present invention has the effect of preventing secondary failures due to separation and coupling and soldering and soldering removal when setting the conventional parameters.
