Vehicle USB media jack for easy assembly {AUTOMOTIVE UNIVERSAL SERIAL BUS MEDIA JACK FOR EASY ASSEMBLY}

The present invention relates to a universal serial bus (USB) media jack for a vehicle that is easy to assemble, and more particularly, a socket to which a USB is inserted and electrically connected, a printed circuit board, and a connection part of a cable are integrated to allow assembly with a housing. It relates to an easy-to-assemble USB media jack for a car that can be done very simply and quickly.

With the advancement of electronic devices and communication technology, the electronic system of vehicles is also evolving so that they can connect to the Internet and exchange information with others through communication networks.

The vehicle's electronic system is basically configured to control or support vehicle driving or vehicle safety-related things, but additionally, it communicates with the vehicle driver's or passenger's external device (such as a high-performance portable terminal) or receives audio input from an external device. It is required to expand the function to perform functions such as outputting to a speaker or supplying energy stored in a vehicle battery or the like to an external device.

In response to such a demand, a universal serial bus (USB) media jack is installed on the front panel of a driver's seat of a vehicle recently, and is used for communication or information sharing or charging.

As a prior art of such a USB media jack, there is a USB connecting cable assembly known through Korean Patent Registration No. 10-1725928.

The prior art is provided with a USB socket in which a plurality of connecting pins are assembled, a circuit board installed at the rear of the USB socket and provided with a plurality of connecting pins, and a plurality of core wires connected to the terminal pins of the connecting pins. It consists of a cable, a plurality of fixing brackets installed on a circuit board to fix the core wire, and a housing installed on the upper part of the fixing bracket to accommodate the fixing bracket and fix the core wire.

In the prior art described above, a circuit board, a fixing bracket, and a housing are mounted at the rear of the USB socket to stably fix the connecting pin of the USB socket and the core wire of the cable, and the connecting pin is not separated from the case of the USB media jack. Disclosed is a configuration in which the substrate is stably supported on a USB media jack.

However, the above-described prior art has a problem in that, as a power circuit unit and a USB data circuit unit are provided together on one circuit board, there is a problem of generating noise due to mutual interference and induced interference between a signal from the power circuit unit side and a signal from the USB data circuit unit side, By arranging the power circuit unit and the USB data circuit unit together, the size of the circuit board increases and the overall size of the USB media jack increases.

In addition, the work of fixing the core wire of the cable is performed by the fixing bracket and the housing, and as the shape of the fixing part of the fixing bracket and the housing is complicated for solid fixing, there is difficulty in manufacturing as well as assembly work. There is also a disadvantage that is not simple, and since the fixing bracket and the housing are a method in which the core wire of the cable is tightly fixed, when installed on the front panel of the vehicle, the fixed part may become loose due to repeated vibrations during the operation of the vehicle, causing poor connection. There is a problem that the electrical connection is severely separated and disconnected.

In addition, the prior art USB connecting cable assembly is not provided with a configuration capable of easily identifying and using the location of the USB media jack while the vehicle is running, especially at night. Therefore, when using the USB media jack while driving, it can be a potential risk factor causing a safety accident. For example, if the driver turns his gaze from the front of the vehicle to check the location of the USB media jack to connect an external device while driving, the driver's response time is delayed in an emergency situation such as a sudden appearance of an object in front of the vehicle. Can cause. As such, there is a need for a USB media jack suitable for vehicle safety.
