An embodiment of the present invention will be described in detail with reference to FIG. 2 and FIG.

The user selects a switch for an automobile and an electric module 100 to be inspected through the display unit 10. Hereinafter, an automotive switch and electric module 100 will be described as an example of an instrument panel switch. The connectors 105 to 108 of the instrument panel switch 100 may be connected to the input / output terminals 51 to 54, respectively. Assuming that each of the connectors 105 to 108 is composed of six pins, only one of the plurality of input / output terminals 51 to 54 is connected to one connector, and the unused line of the input / 55 can be turned off. For example, the control unit 20 turns on the switch element 55 so that the connector 105 can be connected to the lines 1 to 6 of the input / output terminals, and the switch element 55 of the lines 7 to 8 is turned off The switch element 55 is turned on so that the connector 106 can be connected to the lines 9 to 14 of the input and output terminals and the switch element 55 of the lines 15 to 16 is turned off, The switch element 55 is turned on and the switch element 55 of the lines 23 to 24 is turned off so that the switch element 55 can be connected to the input / output terminal lines 17 to 22, The switch element 55 is turned on so that the switch element 55 is turned on and the lines 31 to 32 are turned on so that the switch element 55 is turned off.

The instrument panel switch 100 may include a head lamp leveling device 101, a front deicer 102, a VDC (Vehicle Dynamic Control) 103, and a brightness control switch REOSTAT 104 have. A VDC (Vehicle, Dynamic Control) 103 is connected to a connector 107, a front deicer 102 is connected to a connector 106, and a HLLD (Head Lamp Leveling Device) And the illumination brightness control switch (REOSTAT) 104 is connected to the connector 108. Each of the switches 101 to 104 is connected to the switch / electric module connection part 50 of the automobile various switches and the electric field module inspection equipment 1 through the connectors 105 to 108, ) Can be inspected and the presence or absence of abnormality can be checked.

When the user selects the instrument panel switch 100 through the display unit 10, the control unit 20 reads a program for controlling the input / output terminals 51 to 54 in the storage unit 60 as described above, The specific switch element of each switch element 55 of the switches 51 to 54 is turned on and the specific switch element is turned off. The inspection of the instrument panel switch 100 can check the electrical characteristics of the various switches 101 to 104 connected to the respective connectors 105 to 108 by the control unit 20 in order, The electrical characteristics of only some of the switches 101 to 104 may be inspected. However, in any case, the plurality of switch elements 35 of the function select switches 31 to 34 are controlled by the control section 20. [

For example, when inspecting the instrument panel switch 100, the electrical characteristics of the switches 101 to 104 are checked sequentially through the connector 105, the connector 106, the connector 107 and the connector 108 Such control is performed by the control section 20 by reading the control program stored in the storage section 60. The case where the connector 105 is inspected will be described. In the function selection switch 31, only the voltage switch element is turned on and the remaining switch elements are turned off. In the function selection switches 32 to 34, only the resistance switch element is turned on , And the remaining switch elements can be turned off. The control unit 20 controls the switch element 41 included in the bridge unit 40 so that the function selection switch 31 can be connected to the line 1 of the input / By doing so, the function selection switch 31 can measure the voltage of the switch 101 through the line 1 of the input / output terminal 51.

The control unit 20 includes the function selection switch 32 in the bridge unit 40 so as to be connected to the line 2 of the input / output terminal 51 so that the resistance can be measured through the function selection switches 32 to 34. [ And the function selection switch 33 controls the switch element 41 included in the bridge unit 40 so as to be connected to the line 3 of the input / output terminal 51, The switch 34 can control the switch element 41 included in the bridge portion 40 so as to be connected to the line 4 of the input / Once the voltage and resistance measurements have been completed, other electrical properties can be controlled to be inspected in this manner. The control unit 20 controls the plurality of switch elements 31 to 34 included in the bridge unit 40 so that no signal collision occurs when the plurality of function selection switches 31 to 34 are connected to the input / And controls the on / off state of the switch 41.

In addition, a plurality of electrical characteristics can be combined and controlled by controlling the switch element 41 included in the bridge portion 40. [ For example, when the resistance is measured through the function selection switches 32 to 34, the resistance applied from the function selection switches 32 to 34 is connected to the respective lines 2 to 4 of the input / output terminal 51 But the three resistances applied to the line 2 of the input / output terminal 51 are applied by controlling ON / OFF of the switch element 41 and merging the three resistances applied from the function select switches 32 to 34 It is possible.

On the other hand, when the inspection is completed through the connector 105, the electrical characteristics of the switch 102 can be inspected through the connector 106. In this case, the operation can be performed in the same manner as the connector 105 described above. Of course, the inspection of each of the switches 101 to 104 may be different in the item of the electrical characteristic to be inspected, and the ON / OFF control of the switch element 41 included in the bridge unit 40 may be different .

On the other hand, in the embodiment shown in FIG. 2, four function selection switches 31 to 34 are shown, but the number of function selection switches 31 to 34 is not limited to four. In the case where the number of the function selection switches 31 to 34 is eight, a total of eight electrical characteristics can be simultaneously inspected since one input / output line is output from each of the function selection switches 31 to 34. In the case where the number of function selection switches 31 to 34 is eight, eight lines can be connected to each of the input / output terminals 51 to 54 so as to process eight inputs or outputs at the same time. As a result, the channel for testing the electrical characteristics can be configured as eight channels, and the four channels or eight channels may be suitable for inspection of various switches and electric modules 100 for an automobile. However, the configuration of the channel can be extended any number of times, and the present invention is not limited thereto.

In the above embodiment, only one switch or one electric module is connected to the switch / electric module connection part 50, but the present invention is not limited thereto. For example, a power window switch may be connected to the input / output terminals 51 to 52, and a start switch may be connected to the input / output terminals 53 to 54 to simultaneously perform the inspection. In this case, the electrical characteristics applied from the function selection switches 31 to 32 are input to the power window switches connected to the input / output terminals 51 to 52, and the electrical characteristics applied from the function selection switches 33 to 34 are input / 53 to 54). The bridge unit 40 controls on / off of the plurality of switch elements 41 so that the electrical characteristics applied from the function selection switches 31 to 32 are inputted to the power window switch through the input / output terminals 51 to 52 And the electric characteristics applied from the function selection switches 33 to 34 can be input to the ignition switch through the input / output terminals 53 to 54. [ As a result, the signals from the function selection switches 31 to 32 and the function selection switches 33 to 34 do not collide with each other through the control of the bridge unit 40, and the switch / It is possible to divide into blocks and examine different switches and electric modules at the same time.

As described above, by constructing the bridge section 40 including a plurality of the switch elements 41 by constituting a plurality of the function selection switches 31 to 34, it is possible to simultaneously check various electrical characteristics can do.
