Description

Conduction test equipment such as fuses, A / V jacks, and devices

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a conduction inspection apparatus for fuses, A / V jacks, and the like. More particularly, the present invention relates to fuse conduction inspection, A / V jack conduction inspection, cable conduction inspection, and various types of device conduction inspection. The present invention relates to a conduction inspection device such as a fuse, an A / V jack, and an element that enables multi testing for simultaneously.

In general, a multimeter is an instrument that can inspect (measure) the voltage, current, and resistance of an element as an inspection component (a) with one device, as shown in FIG. ), And the multimeter's selector dials allow you to measure the resistance, current, and voltage of each component or device. The resistance, current, and voltage values of each device or component measured are checked by means of the pure gold value indicated by the needle in the case of analog, and by the screen of the multimeter in case of digital display.

Conventional conduction inspections of fuses, A / V jacks, and other devices measure the voltage, current, and resistance of various devices, and measure both ends of the component to be tested to act as an input to the multimeter. It consists of the passive connection probe 31 which is a connection means between the multimeter 1 and components.

The conduction test of the fuse, the A / V jack, the element, etc. thus constructed is carried out by the following procedure.

For the input from the component to the multimeter, the black probe of the passively connected probe 31 is plugged into the COM which serves as the ground of the multimeter 1 and the other wire into the V position.

The position of the selector dial of the multimeter 1 connected to the passive connection probe 31 is positioned where there is a phone speaker indication (FIG. 1) which enables the conduction test by ringing a buzzer.

Both ends of the component to be inspected are connected to the tip 32 of the probe by using the manual connection probe 31. At this time, when the part to be inspected is turned on, the buzzer built into the multimeter will ring to inform the inspector of the conduction of the part. have.

However, the conduction test of such conventional fuses, A / V jacks, devices, etc., places the selection dial of the multimeter 1 measuring resistance, voltage, and current at the position of the phone speaker for conduction test, and the conduction of the parts. In the case of inspection, since only one component, such as fuses, A / V jacks, and various cables, needs to be measured one by one, the inspection takes a long time and is inconvenient to test.

Therefore, the present invention has been invented to solve the above problems, and to compensate for the above disadvantages, the battery (battery) and buzzer, LED and protection resistor, buzzer to inspect the fuse and A / V jack and each component at the same time It is an object of the present invention to provide a conduction inspection device such as a fuse, an A / V jack, and an element using a selection switch.
