Description

  The present invention relates to a cable harness and a television receiver using the cable harness.

  A limited reception system is adopted in a television receiver that receives and reproduces digital terrestrial waves, BS broadcasts, and CS broadcasts. In such a television receiver, it is necessary to authenticate video display by connecting a contact type IC card (B-CAS (registered trademark) card) storing authentication information. This IC card is used by being inserted into a card slot of a television receiver. Since this IC card records reception contract information on a card-by-card basis, it is the same with other television receivers by replacing the card on which information such as a satellite broadcast reception contract or pay broadcast viewing contract is recorded. Can be viewed and recorded. For this reason, even when a television receiver is replaced, the same viewing and recording as before replacement can be performed by using an IC card which has been used conventionally. For this reason, a television receiver is generally provided with an insertion slot through which an IC card can be inserted from outside the main body of the television receiver.

  On the other hand, some TV receivers are designed to be waterproof for use outdoors or in bathrooms. Such waterproof TV receivers are waterproof and have a card slot. Since water is generated from the card insertion slot, it is necessary to waterproof the card insertion slot.

  In Patent Document 1, a television main body having a card insertion slot for a CAS (Limited Reception System) card is attached to the indoor side wall surface of the bathroom wall, and the rear surface of the TV main body is closely attached to the indoor side wall surface via an annular water sealing packing. And the card insertion slot facing the inside of the water-stopping packing is described.

  By the way, in a small-sized television receiver or an inexpensive television receiver, it is difficult in terms of space to waterproof the card slot port of the television receiver, and there are cases where it cannot be adopted in terms of cost. For this reason, a special built-in card or a special built-in mini card that can be inserted into the television receiver has been provided from the shipping stage.

JP 2012-85088 A

  However, in recent years, the special built-in card or the special built-in mini card described above has been abolished. In order to cope with this, in a waterproof television, it is necessary to attach a normal IC card from the outside of a waterproof casing as in the technique described in Patent Document 1.

  However, if such a waterproof structure is adopted for the conventional waterproof television receivers, the conventional molds and parts have to be changed drastically. There is a problem that the cost of preparing parts is high.

  The present invention has been made in view of the above-described problems, and it is an object of the present invention to make it possible to use an externally mounted IC card without significantly increasing the cost of a television receiver that has been conventionally provided and suppressing an increase in cost. And

  The device according to claim 1, which solves the problem, has a board portion on which a card socket into which a contact type IC card storing authentication information can be inserted, and one end portion connected to an output terminal of the card socket. And an authentication signal cable in which a connector for transmitting an authentication signal is disposed at the other end, and the card socket, the board portion, and the authentication signal in a state where at least the card insertion port of the card socket is exposed. A waterproof coating covering one end of the cable is provided, and the authentication signal cable is provided with RF connectors at both ends to transmit an RF signal from the television antenna, and power connectors are provided at both ends to supply power. A cable harness is characterized in that a power cable is arranged in parallel and a single cable portion is formed by covering them together.

  Similarly, the invention described in claim 3 includes a front panel and a back panel that covers the back side of the front panel to form a waterproof space, and the waterproof space includes an image display that is displayed on the front panel. And an audio output unit, an image display unit, and an audio output unit, and an input terminal unit including an RF signal receiving terminal, an authentication signal receiving terminal, and a power input terminal, and signals from these input terminal units And a TV drive board that drives the image display unit and the audio output unit based on the power, and the RF signal receiving terminal, the authentication signal receiving terminal, and the power input terminal include: The connection connector, the RF connector, and the power connector of the cable harness according to claim 2, wherein the authentication signal, the RF signal, and the power are supplied, and the cable is connected. Through the cable portion is the back side panel of the table harness, between the cable part and the rear panel is a television receiver, characterized in that the waterproof processing is given

  Similarly, the invention according to claim 4 is the television receiver according to claim 3, wherein the back panel can be attached to a wall part in which an insertion hole through which the cable harness can be inserted is formed, and the cable part is The RF signal receiving terminal, the authentication signal receiving terminal, and the power input terminal of the cable harness are led to the outside through the insertion hole, and are connected to an external antenna terminal and a power source through a hole formed in the wall. It is connectable.

  Similarly, the invention described in claim 5 is such that the television receiver according to claim 3 or 4 receives a signal from a wireless remote control device and controls the television drive board to control the television channel and audio volume. A wireless remote control receiver for controlling is provided.

  According to the present invention, it is possible to use an externally mounted IC card without greatly modifying the conventionally provided television receiver and suppressing an increase in cost.

That is, in the cable harness according to the first aspect, a card socket into which a contact type IC card for broadcast authentication can be inserted is arranged on the board portion, and one end of the authentication signal cable is connected to the output terminal of the card socket and extends. A connecting connector for transmitting an authentication signal is disposed at the other end, and the waterproof covering covers the card socket, the board portion, and one end of the signal cable in a state where at least the card insertion port of the card socket is exposed. The cable is provided with an RF cable having RF connectors at both ends to transmit antenna signals from a television antenna, and a power cable having power connectors at both ends to supply power, and these are waterproofed together. The cable part is formed.
Therefore, an externally mounted IC card can be used without significantly changing the configuration of the television receiver by disposing a waterproof card socket at the tip of the cable portion drawn from the television receiver. Further, since the RF harness and the power cable are arranged in parallel in the cable harness, the RF signal and power can be supplied to the television receiver.

  In the cable harness according to claim 2, since the AV cable having the AV connector at both ends and transmitting the audio signal and the image signal is arranged on the wire portion, the AV signal can be supplied from the outside to the television receiver. .
