## Abstract

An electric jack for the connection of an electric connector, including at least one plug hole disposed on a side wall of the jack for the installation of display means, sets of terminals respectively disposed in the at least plug hole at one end, each of the terminals having a receiving section, said receiving section having a clamp portion at one end and a mounting tail end at the other end extending out of the jack and adapted for connection to power source, and at least one display means for example LEDs respectively mounted in the at least one plug hole and detachably connected to the terminals, each of the at least one display means having a plurality of electrically conductive pins respectively plugged into the receiving section of the terminals in the respective plug hole, and a front side projecting out of the jack through which the display means can be conveniently removed out of the respective plug hole by a pliers or like tool for a replacement.

## Claims

### Claim 1

An electric jack for the connection of an electric connector, comprising at least one plug hole disposed on a side wall of the jack for the installation of display means, a plurality of terminals respectively disposed in said at least one plug hole at one end, each of said terminals having a receiving section, said receiving section having a clamp portion at one end facing the respective plug hole and a mounting tail end extending out of the jack and adapted for connection to a circuit board, and at least one display means respectively mounted in said at least one plug hole and detachably connected to said terminals, each of said at least one display means having a plurality of electrically conductive pins respectively plugged into the receiving section of the terminals in the respective plug hole.

### Claim 2 (depends on 1)

The electric jack of claim 1 wherein each of said at least one display means has a front displaying side projecting out of the jack.

### Claim 3 (depends on 1)

The electric jack of claim 1 wherein each of said at least one display means is a light emitting diode.
