Field of the Invention The present invention relates to a connection cord for an electronic product, and more particularly, to a connection cord connection device for an electronic product that can simultaneously transmit video and audio signals by one connection cord.

In general, a connection code for an electronic product is a cable for transmitting a video signal or an audio signal output from an electronic product to another electronic product, and is commonly used for televisions, video cassette recorders, and audio systems.

As such, electronic products to which connection cords are connected are in demand as the AV system (Audio & Video) becomes more common. For example, a television, a video cassette recorder and an audio system may be connected to each other so that the respective connection codes are connected to the back of the television, the video cassette recorder and the audio system so as to mutually transmit video signals (or video signals) or audio signals (or audio signals). Is connected to.

An example of a connection cord for an electronic product of the prior art, as shown in Figure 1, the connection cord 1 is provided with a pin-shaped first terminal (1a) in the center, in the circumferential direction of the first terminal (1a) The tubular second terminal 1b is provided. An insulator (not shown) is filled between the first terminal 1a and the second terminal 1b to prevent a short circuit.

Moreover, the coating | covering material 1c which consists of rubber | gum and synthetic resin is coat | covered on the outer peripheral surface of the 2nd terminal 1b, and the cable 1d is inserted in the back inner side of the coating | covering material 1c. The 1st terminal 1a and the 2nd terminal 1b are connected to the electric wire which is not shown of the cable 1d, and are comprised in the both ends of the cable 1d.

In addition, the user may not be able to distinguish between the video and audio signal ports of the electronic product, and may change the connection cord 1 to connect. For example, in the case of the AVE system, a power cable, a speaker cable, a tutor antenna cable, and a converter cable are connected to the back of the system, so that it is difficult for a user to distinguish whether the connection port corresponds to a video or audio signal. . In addition, the back configuration and wiring of the AVE system is complicated, and there is a problem that it is cumbersome and inconvenient to use.

In order to solve this problem, the connection cords (1) are manufactured in various colors so that they can be distinguished. However, in order to distinguish whether the connected connection cords (1) are used for video signals or audio signals, a problem that a user must check is required. have.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to reduce the production cost of the electronic products using the connection code while simultaneously transmitting the video and audio signal by one connection code To provide a connection cord connecting device for electronic products that can be made.

Interconnect. That is, the first, second, third and fourth terminals 11, 12, 13 and 14 provided at both ends of the connection cord 10 are made of the connection terminal 20 provided in the respective electronic products. Since the terminals are connected to the 1,2,3 and fourth terminals 11, 12, 13 and 14, the signals corresponding to the respective terminals, that is, the video signals and the audio signals, can be connected.

For example, the first and second terminals 11 and 12 of the connection cord 10 and the first and second connection terminals 21 and 22 of the connection terminal 20 connect audio signals, and the connection cord. The third and fourth terminals 13 and 14 of (10) and the third and fourth connection terminals 23 and 24 of the connection terminal 20 connect the video signals so that the video signal and the audio signal can be connected at once. Can be connected.

Since the connection cord 10 and the connection terminal 20 connect the video and audio signals at one time, the user who includes the connection cord 10 in the electronic product or purchases it separately can connect the video and the audio by one connection cord 10. Enable audio signal connection. Therefore, the user is more easily connected to the connection code 10 for connecting the video and audio signals, and also provided on the back of the electronic product by one connection cord 10 for transmitting the video and audio signals at once Wiring becomes simpler.

The above-described embodiment is merely an example of a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above, and may be appropriately changed within the scope of the same concept.

As described above, the connection cord of the present invention includes first, second, third, and fourth terminals, and the first and second connection terminals include first, second, third, and fourth connection terminals to connect video and audio signals between electronic products. do. Therefore, the user who connects the connection cord does not need to distinguish the video and audio signals, so that the user can connect the connection cord more easily, and the back configuration of the electronic product to which the connection cord is connected is simpler and the production cost of the electronic product is reduced. Has a very useful effect.
