Description

  The present invention relates to an electronic device having a connector for electrical connection with a peripheral device, another electronic device, or the like, and in particular, the connector is strengthened in grounding (GND) such as HDMI (High-Definition Multimedia Interface). The present invention relates to a connector device for an electronic device suitable for use in an electronic device having a connector that requires a shorter harness.

  As a conventional connector device of this type of electronic device, for example, there is one described in Patent Document 1. Patent Document 1 describes an external connector holding structure of an electronic device. The external connector holding structure of an electronic device described in Patent Document 1 is “an outer casing of an electronic device, a printed circuit board disposed in the outer casing, and a printed circuit board disposed on the printed circuit board, and a distal end portion thereof is an external portion. An external connector exposed from an insertion hole formed in the housing and a part of the outer housing that is detachable from the outer housing, and is divided at an insertion hole portion for exposing the distal end portion of the external connector And an external connector holding member provided with a holding portion for holding the external connector in the front-rear direction when attached to the outer casing.

  According to the external connector holding structure of the electronic device having such a configuration, “the connector holding member can receive the force applied to the mounting portion between the external connector and the printed circuit board when the plug is attached to or detached from the external connector. The burden on the mounting portion between the connector and the printed circuit board can be reduced, and the occurrence of accidents such as backlash of the mounting portion, detachment of the external connector, breakage, and peeling of the circuit pattern can be expected.

  However, in the conventional electronic device connector device disclosed in Patent Document 1, the printed wiring board to which the connector is soldered is fixed to a mounting bracket made of sheet metal, and the mounting bracket is screwed to the housing of the electronic device. It was the composition to do. For this reason, since the connector itself is not configured to directly contact a sheet metal casing or component, it is necessary to separately provide ground (GND) wiring, and the ground of the electronic device is weak. It was.

  In general, in this type of electronic device connector device mounting method, a connector and a control device or electronic device electrically connected thereto are fixed in advance to a housing or the like, and then the connector is soldered. The operation | work which connects the terminal part of the flexible wiring board pulled out from the wiring board to connection parts, such as a control apparatus, is required. Therefore, it is necessary to secure a sufficiently large length of the terminal portion so that the operation of connecting the terminal portion to the connecting portion can be easily performed as a final process at the time of assembly. As a result, the communication characteristics may become unstable due to the length of the cable.

  In particular, in recent years, a connector called HMDI (High-Definition Multimedia Interface) has been used in response to a request for improvement of electrical characteristics (removal of unnecessary radiation) and stabilization of communication characteristics. This HMDI is a display connection technology DVI (Digital Visual Interface) constructed based on TMDS (Transition Minimized Differential Signaling), which is the de facto standard for digital video interfaces, with specifications for AV (Audio Visual). , Hitachi, Matsushita Electric Industrial, Philips, Sony, Thomson Multimedia, and Toshiba, and Silicon Image, a semiconductor manufacturer for high-speed serial transmission, is an interface standard for next-generation TVs.

  Conventionally, there is a DVI digital connection standard for connecting a PC (Personal Computer) and a display. HMDI is a further development of DVI. Up to now, a plurality of cables have been used for video, audio, and control signals for connection between devices. By using this HMDI, a single cable can be used for connection. In addition, since the control signal is compatible with bidirectional transmission, a single remote controller is provided by relaying the control signal from a monitor to a device such as an STB (Set-top Box) or a DVD player connected via HDMI. It becomes possible to operate the equipment of the whole home theater.

This HMDI is indispensable for improving electrical characteristics and stabilizing communication characteristics compared to other connectors. For this purpose, the grounding (GND) function is strengthened and the length of the connection cable (connection) is shortened. It will be necessary.
Japanese Utility Model No. 6-38536 (Japanese Utility Model Publication No. 2-3068)

  The problem to be solved is that, in the connector device of the conventional electronic device, the connector itself is not directly in contact with the sheet metal casing or component, and a ground (GND) wiring is provided separately. Since it was necessary, the grounding (GND) function of the electronic device was weak. In addition, after fixing the connector, the control device, the electronic device, etc. to the housing in advance, the terminal portion of the flexible wiring board drawn out from the printed wiring board to which the connector is soldered is connected to the connection portion of the control device, etc. Since the work is required, it is necessary to ensure a sufficiently large length of the terminal portion, and as a result, there is a possibility that the communication characteristics may become unstable.

A connector 84 to which different types of plugs 83 are connected is provided on the side of the connecting device 82 opposite to the lead side of the cord 81.

As described above, according to the connector device of the electronic device of the present application , after the connector such as HMDI is temporarily fixed to the substrate holder (fixing frame) and assembled to the outer case (housing) in the temporarily fixed state. Since the connection terminal (harness) of the flexible wiring board connected to the connector is connected to the connector of the main board, even a short flexible wiring board can be easily connected. As a result, the length of the wiring (harness) can be shortened to improve the electrical characteristics (removal of unnecessary radiation) and stabilize the communication characteristics. In addition, since the connector shell is in direct contact with the substrate holder, the ground (GND) characteristics can be enhanced, and adverse effects due to static electricity or the like can be prevented.
