## Abstract

A multimedia cable includes a casing, a terminal pin, an audio signal unit, a video signal unit, and a control lever. The terminal pin is mounted to the casing so as to be rotated with respect to a rotary shaft, and is configured such that first and second four-conductor terminals are arranged on respective sides of the rotary shaft. A audio signal unit comprising three-conductor connection pins each one end of which is rotatably mounted in the casing and audio cables each of which is connected with said each one end of the three-conductor connection pins respectively. A video signal unit comprising four-conductor connection pins mounted opposite the three-conductor connection pins, each one end of which is rotatably mounted in the casing and video cables which are connected with said each one end of the four-conductor connection pins. The control lever is connected to both the three-conductor connection pins and the four-conductor connection pins to connect either the three-conductor connection pins or the four-conductor connection pins to the terminal pin.

## Claims

### Claim 1

A multimedia cable, comprising:
a casing;
a terminal pin mounted to the casing so as to be rotated with respect to a rotary shaft, and configured such that first and second four-conductor terminals are arranged on respective sides of the rotary shaft;
an audio signal unit comprising three-conductor connection pins each one end of which is rotatably mounted in the casing and audio cables each of which is connected with said each one end of the three-conductor connection pins respectively;
a video signal unit comprising four-conductor connection pins mounted opposite the three-conductor connection pins, each one end of which is rotatably mounted in the casing and video cables which are connected with said each one end of the four-conductor connection pins; and
a control lever connected to both the three-conductor connection pins and the four-conductor connection pins to connect either the three-conductor connection pins or the four-conductor connection pins to the terminal pin;
wherein the casing comprises a concave depression therein, corresponding to a direction of rotation of the terminal pin; and the terminal pin is rotated so as to pass through the concave depression.

### Claim 2 (depends on 1)

The multimedia cable as set forth in claim 1, wherein:
the terminal pin is configured such that a convex head portion is formed in one end thereof and a concave head portion is formed in the other end thereof; and
the control lever is configured to be able to be raised and lowered by coming into contact with the convex head portion or the concave head portion, thus selectively connecting either the three-conductor connection pins or the four-conductor connection pins to the terminal pin.

### Claim 3 (depends on 2)

The multimedia cable as set forth in claim 2, wherein the control lever is supported upwards by a spring, the spring stores elastic potential while the control lever is lowered in case where the control lever comes into contact with the convex head portion of the terminal pin, and the elastic potential stored in the spring allows the control lever to be raised in case where the control lever comes into contact with the concave head portion of the terminal pin.

### Claim 4 (depends on 3)

The multimedia cable as set forth in claim 3, wherein the three-conductor connection pins of the audio signal unit are electrically connected with respective AUX-L, AUX-R and AUX-GND conductors of the first four-conductor terminal of the terminal pin.

### Claim 5 (depends on 3)

The multimedia cable as set forth in claim 3, wherein the four-conductor connection pins of the video signal unit are electrically connected with respective AUX-L, AUX-R, VIDEO-IN and AUX-GND conductors of the first four-conductor terminal of the terminal pin.
