Description

RCA PIN JACK {RCA PIN JACK}

The present invention relates to an RCA pin jack, and more particularly, to a PCB copper foil surface, which is embedded in a ground can such that the upper portion of a connector body cylindrical body assembled with any one selected contact terminal of a standard mono function or a switch function is exposed. Later, it is directly mounted on the PCB, connected to the circuit pattern, and fixed to the case so that the connector formed integrally with the connector body cylindrical body is exposed to mass production at a low cost by simplification of mold production. It's about the RNC pinjack.

In general, the pin jack is mounted for the terminal of the V system, such as TV, audio, video and CD player, DVD player, and is a device that accommodates the insertion and detachment of the pin plug.

In addition, the pin jack board includes a plurality of cylindrical terminal portions having jack holes, a metal plate provided on the circumferential surface of the terminal portion to form a frame ground, and a terminal terminal.

The pin jack board is connected to the printed circuit board in the home appliance through the terminal terminal in the state of being installed on the front (and / or rear) of the home appliance externally, and its use value due to the spread of home theater system. Is rising.

That is, when the plug jack of the external device is connected to the jack hole of the cylindrical terminal part, the pin jack board turns off the signal input / output of the home appliance, and enables the signal input / output of the external device connected through the plug jack.

However, in the related art, a control method of inserting a plug jack into a jack hole of a cylindrical terminal part to turn off signal input / output of a home appliance and turning on signal input / output of an external device, while inserting a jack hole into the jack jack and generating an electrical connection signal, Due to the circuit switching device or IC chip configured in the printed circuit board in the device, the circuit configuration of the devices in the printed circuit board has to be complicated, and when an error occurs in the switching device or the IC chip, The error correction was hard work.

In addition, since the frame ground of the metal plate provided in the conventional pin jack board forms a loop in which interference occurs without being separated from the signal ground formed in the printed circuit board in the home appliance, the current flowing through the signal ground of the printed circuit board is frame ground. The high impedance is applied to the frame ground while affecting the signal, and the noise has to be included in the signal when input / output by the external device.

On the other hand, contact terminals processed with non-ferrous metals become longer and shorter depending on the position of the RCA pin jack arrangement, and therefore, to the counterparts and home appliance boards.Therefore, there are various types of raw materials and molds. There was a problem of uneconomical use due to the burden of personnel.
