Description

Connector and tuner including the same}

This embodiment relates to a tuner comprising a connector thereof.

The electronic device may perform a certain operation using the data stored therein or receive a signal from the outside to perform the operation. In this case, the electronic device may receive a signal wirelessly from the outside, but can generally receive the signal through a cable line.

For example, a TV, which is one of electronic devices, may receive a broadcast signal such as a terrestrial broadcast signal, a cable broadcast signal, or a satellite broadcast signal through a cable line to display an image. Specifically, as the male connector is mounted on the cable line for transmitting the broadcast signal, and the female connector is mounted on the TV, the male connector may be inserted into and connected to the female connector, thereby A broadcast signal can be smoothly transmitted to the TV.

In general, an electronic device may not operate properly due to various reasons. One of the causes is when the electronic device is not connected to the cable line or the contact is in a bad state. That is, the male connector of the cable wire is not inserted into the female connector of the electronic device or is connected in a bad manner. However, the user may not easily identify such a defective state of the connection, and may feel uncomfortable in determining the cause of the malfunction of the electronic device.

In addition, since the TV control module searches for a broadcast channel by assuming that the male connector and the female connector are coupled regardless of whether the male connector and the female connector are connected, there is a problem that the user experience is reduced due to an operation error.

The present invention is proposed to improve the above problems, and to provide a tuner including a connector that can detect the connection state of the signal terminal.

The connector according to the present embodiment includes a housing in which a pinhole is formed at a front surface and a thread is formed at a side adjacent to the front surface; A core wire disposed in the housing; An insulating member disposed on a side of the housing adjacent to the screw thread; And a terminal sensing unit disposed outside the insulating member and spaced apart from an outer surface of the housing. When an external signal terminal is coupled to the housing, the terminal sensing unit and the external signal terminal contact each other.

In this embodiment, since the voltage of the terminal sensing unit varies according to the coupling of the signal terminals, the main IC has an advantage of easily detecting the coupling state of the signal terminals.

Therefore, since the input signal of the signal terminal can be provided through the core wire only in the state in which the signal terminals are coupled, there is an advantage of ensuring the user's reliability in accordance with product driving.

A pinhole 103 may be formed at the center of the terminal coupling surface 106 to communicate the inside and the outside of the housing 102. The pin hole 103 may have a pin 3 of the signal terminal 5 inserted therein. For this reason, the pin 3 and the core line 120 to be described later may be electrically connected.

When the outer surface of the housing 102 excluding the rear surface of the housing 102 opposite the terminal coupling surface 106 and the terminal coupling surface 106 is referred to as the side surface of the housing 102, the housing 102 The side of can be partitioned into two regions. One region is a region relatively adjacent to the terminal coupling surface 106, and may be defined as a terminal coupling portion A1 extending backward from the terminal coupling surface 106 of the housing. Another region is defined as a mounting portion A2 relatively adjacent to the rear surface of the housing 102 and adjacent to the terminal coupling portion A1 and having an insulating member 140 and a terminal sensing unit 150 to be described later.

In addition, the inner surface of the cover 2 facing the terminal coupling part A1 in the signal terminal 5 may be formed with a screw groove or a thread for screw coupling with the upper thread 104 or the screw groove. Therefore, the signal terminal 5 may be screwed to the outer surface of the terminal coupling portion A1 by rotating the cover 2 while the pin 3 is inserted into the pinhole 103.

The outer surface of the mounting portion A2 may be formed to be recessed inward relatively than the height of the thread 104. That is, the protruding height of the outer surface of the mounting portion A2 is formed to be lower than the protruding height of the outer surface of the terminal coupling portion A1.

The insulating member 140 and the terminal sensing unit 150 are coupled to the mounting surface 105 of the mounting unit A2. The insulating member 140 and the terminal detecting unit 150 are formed in a ring shape in which a hole is formed at the center of the cross section, and an inner circumferential surface of the hole formed in the insulating member 140 is formed in the mounting surface 105.

The core wire 120 may be electrically connected to the pin 3 of the signal terminal 5 inserted through the pinhole 103. Thus, an input signal may be provided from the signal terminal 5 and transmitted to the main IC 190. When the signal terminal 5 is coupled to the connector 101, one end of the core wire 120 may contact the pin 3, and the other end may contact the printed circuit board of the main IC 190. .

In detail, the core wire 120 may include a terminal unit 124 and a signal transmission unit 126 extending rearward from the terminal unit 124 to be in contact with the printed circuit board. The terminal portion 124 is formed with a coupling hole 122 into which the pin 3 is fitted. The coupling hole 122 may be formed on the front surface of the core wire 120.

The bent portion 123 may be configured to be bent inwardly in a direction in which each of the plurality of plates are close to each other. Due to the bent portion 123, the plurality of plates may be in contact with each other in the bent portion 123. The bent portion 123 may be located at the rear of the coupling hole 122.

The plurality of plates may be a metal material having elastic force. The elastic force of the plurality of plates may act in a direction in which the bent portions 123 are close to each other. Therefore, when the pin 3 is coupled to the core wire 120, the bent portion 3 may press the outer surface of the pin 3 in a state spaced apart from each other. When the pin 3 is separated from the core line 120, the bent portions 3 may be in contact with each other by an elastic force.

The signal transmission unit 126 may extend rearward from the rear surface of the terminal unit 124. The signal transmitter 126 may have an area bent at least once. An end of the signal transfer unit 126 may be electrically connected to the printed circuit board. As a result, the signal input from the pin 3 may be transmitted to the printed circuit board.

The insulating member 140 is disposed between the terminal detecting unit 150 and the housing 102 to insulate the terminal detecting unit 150 from other components. The insulating member 140 may be formed of a resin material. The insulating member 140 may have a rib 142 protruding outward and hooked with the terminal detecting part 150. Therefore, when the terminal detecting unit 150 is coupled to the outer surface of the insulating member 140, the rib 142 presses the outer surface of the terminal detecting unit 150, thereby coupling force with the terminal detecting unit 150. This can be high.

However, when the signal terminal 5 is coupled to the connector 101, the terminal sensing unit 150 may have a ground voltage formed by an electrical connection with the cover 2 or the housing 102. . Accordingly, the main IC 190 may detect that the voltage of the terminal detecting unit 150 is lowered, and may detect that the signal terminal 5 is coupled to the connector 101.

The signal terminal 5 is screwed to the connector 101 to be in contact with the terminal sensing unit 150 as the cover 2 moves, so that the terminal sensing unit 150 is connected to the housing 102 or the housing 102. The low level voltage may be formed in the terminal sensing unit 150 by being electrically connected to the cover 2.

Therefore, according to the present embodiment, since the voltage of the terminal detecting unit 150 varies according to the coupling of the signal terminal 5, the main IC 190 easily detects the coupling state of the signal terminal 5. There is an advantage to this. Therefore, since the input signal of the signal terminal 5 may be provided through the core wire 120 only in the state in which the signal terminal 5 is coupled, the user's reliability may be secured according to driving of the product. have.
