Abstract

An apparatus for displaying electrical measurement of distributor of motor vehicle comprises a distributor and a circuit module including at least one display unit and a circuit board in distributor under input and output terminals and electrically connected thereto by contacting. Display unit is electrically connected to circuit board and located on a side of distributor for ease of reading. Thus current representing an electrical measurement of distributor may be shown on display unit.

Claims

a circuit module including at least one display unit and a circuit board;

wherein said circuit board is provided in said distributor under said input and output terminals and is electrically connected thereto by contacting, and said display unit is electrically connected to said circuit board and is located on a side of said distributor, thereby showing current representing an electrical measurement of said distributor on said display unit via circuit board.

2. The apparatus of claim 1, wherein said distributor comprises a plurality of fuse blocks each provided in a branch of said distributor.

3. The apparatus of claim 1, wherein said display unit comprises a plurality of light emitting diodes (LEDs).

4. The apparatus of claim 3, wherein said display unit further comprises a digital display.

5. The apparatus of claim 4, wherein said digital display is a liquid crystal display (LCD).

6. The apparatus of claim 4, wherein said circuit module further comprises a button being operative to switch values shown on said digital display.

7. The apparatus of claim 1, further comprising a casing extended from a side of said distributor and a window on said casing disposed corresponding to said display unit.

8. The apparatus of claim 7, wherein said display unit is disposed vertically on a side of said distributor.

9. The apparatus of claim 7, wherein said display unit is disposed slantwise on said side of said display unit.

10. The apparatus of claim 9, wherein said circuit board comprises a plurality of electrical elements in said casing.

11. The apparatus of claim 10, wherein said electrical elements are under said circuit board.

12. The apparatus of claim 11, further comprising a plurality of slots on bottom of said distributor for receiving said electrical elements.

13. The apparatus of claim 11, further comprising a recess on bottom of said distributor for receiving said electrical elements.

14. The apparatus of claim 1, wherein said distributor further comprises a cover.
