Abstract

A connecting device applicable to a battery terminal can display the electrical condition, such as the voltage of power and the condition of the fuses of each line. The connecting device includes a main body having a clamp at one end for fixing to the battery terminal, and the other end for carrying a display unit and connecting cables of appliances. The display unit makes the connecting device displayable with electrical conditions directly without the need of using other testing devices.

Claims

1. A connecting device applicable to a vehicular battery terminal comprising at least:

an electrically conductive main body, having one end formed with a clamp for fixing to the battery terminal and leading power to at least an appliance, and another end formed with a carrier for cables;

a display unit, mounted on said main body, comprising;

a circuit board;

a plurality of connecting pins, inserted into the carrier for linking the battery power to the circuit board;

a display mounted on the circuit board, showing the electrical status of the battery power; and

a window, made of a transparent material and mounted on said display unit for protecting and showing the same.

2. A connecting device applicable to a vehicular battery terminal as recited in claim 1 wherein the carrier is formed with a recess for mounting the display unit.

3. A connecting device applicable to a vehicular battery terminal as recited in claim 1 wherein the carrier is formed with a plane at the top of the main body for mounting the display unit.

4. A connecting device applicable to a vehicular battery terminal as recited in claim 1 wherein the carrier is formed with a plane lower than top of the main body for mounting the display unit.

5. A connecting device applicable to a vehicular battery terminal as recited in claim 1 wherein the display is a liquid crystal display.

6. A connecting device applicable to a vehicular battery terminal as recited in claim 5 wherein the display unit further comprises a plurality of light emitting diodes.
