Description

RCA connection socket

The present invention relates to a socket for the connection of a United States Radio Company (RCA), and more particularly to a socket for RCA connection, which has a socket body type which allows a standard contact terminal (plug) which can function as a single tone or a stereo switch and has a color to be inserted. The cylindrical system is received in a grounding sleeve and the upper portion is exposed outside the sleeve. The cylindrical body is vertically mounted on a printed circuit board (PCB) and connected to a circuit pattern formed on the copper film of the PCB, and the PCB is connected. The socket is fixed to a casing so that the socket integrally formed with the socket body-integrated cylindrical body is exposed, whereby the area occupied by the (effective) path of the contact terminal contacting the plug of the RCA connection socket is configured by the PCB circuit pattern. Instead, the circuit pattern of the PCB can satisfy the function of the electronic instrument as a single tone or stereo signal; thus, not only can the non-ferrous metal raw materials used be reduced, but also the cost can be saved, and the manufacturing process and the die used can be simplified, and at the same time Standardize stamped parts to improve productivity.

Generally, the plug-in connector is provided as an operating system (hereinafter referred to as "V system") such as a television, a record player, a video recorder, a CD player, a digital video disc (DVD) player, or the like. The necessary components for connecting the terminals and allowing the pin type plug to be inserted and removed.

Further, the socket (socket) plate is composed of a plurality of cylindrical socket bodies having a socket, and is provided at a peripheral portion of the socket body to form a metal plate of the chassis ground and a plurality of contact terminals.

The socket board constituting the above is connected to the printed circuit board (PCB) of the electronic appliance via the terminal provided in an outwardly exposed state on the front side (and/or the back side) of the electronic body, and with the popularity of the home theater system, The practical value is even more increased.

Specifically, the socket board is configured to enable the signal input/output of the electronic appliance to be inactive (invalid) when the plug of the external device is inserted into the jack of the cylindrical socket, and then the external device is connected by the plug. Signal input/output is valid.

However, conventionally, the plug is inserted into the jack of the cylindrical socket to disable the signal input/output of the electronic appliance, and then the input/output of the external appliance is activated to become effective. The control system is installed on the PCB of the electronic appliance. Moreover, when the plug is inserted into the jack, the switching element or the integrated circuit (IC) chip of the electrical connection signal is generated, and therefore, the circuit structure of the component of the PCB is complicated, and it is difficult when the switching element or the IC chip malfunctions. Fix its bug.

Moreover, the grounding of the metal plate casing provided on the conventional socket board forms a loop, which is not separated from the grounding of the signal provided on the PCB of the electronic appliance, so that the signal flowing through the PCB is grounded. The current affects the grounding of the chassis, thus causing high impedance to be applied to the chassis ground. As a result, when the external device performs signal input/output, the signal cannot avoid noise (noise) due to the high impedance.

In addition, the contact terminals made of non-ferrous metals have different lengths depending on the arrangement position of the RCA connector from the matching device to the circuit board of the electronic device. Therefore, the types of raw materials used and the types of the molds are various, resulting in various types. In order to cope with the material management costs and raw material costs brought about by the demand and supply of raw materials, and the financial burden required for mold development costs, there is no profit.

According to the above-mentioned RCA connection socket structure, all the contact terminals, the grounding sleeve, the socket body integrated colored cylinder body and the like are all produced by the simplification design of the mold, and therefore, the cost of the non-ferrous metal material for the terminal can be Since the standard specifications of the materials used for miniaturizing the contact terminals are simplified, and the supply and demand of the materials can be easily adapted, the cost of the raw materials can be reduced, and the supply and demand of the materials can be adapted. Moreover, the conditions of the manufacturing process, the assembly stability and the productivity can be improved due to the batch and on-line production system of the connection socket assembly line. Moreover, since the online assembly workers can simultaneously perform the production and assembly system of the on-line process quality during the operation, it is possible to greatly reduce the occurrence of defective products.

In addition, the traditional spacers (gaskets) with the recognized color can be replaced by the integral body of the socket body. Therefore, the cost of the mold can be reduced, the manufacturing time of the parts can be shortened, and the assembly engineering can be reduced, thereby reducing the production cost. . Further, it is possible to use the same connection socket for horizontal or vertical type installation which is different depending on the PCB mounting type developed by the manufacturer (developer).

Furthermore, the connection socket required for the product of the manufacturer can be used for various electronic appliances, and the deformation of the basic shelf caused by the length-based assembly of the connection pin terminals of the same socket is used. Because the PCB can block the through hole leading to the inside of the electronic appliance, it can prevent any metal tool that may cause electric shock from being inserted into the through hole from the outside, thereby preventing the high-voltage electric shock inside the electronic appliance from happening.
