Description

  The present invention relates to a connector arrangement structure such as a DC jack for connecting an AC adapter and an electronic device.

  Conventionally, electronic devices having portability such as notebook personal computers (hereinafter referred to as notebook PCs) are usually battery-driven when being carried and used with an AC adapter attached in an office or the like. Generally, the AC adapter is electrically connected by inserting a plug into a DC jack attached to the electronic device body so that the AC adapter can be detached from the electronic device. The DC jack is fixed to the internal substrate of the electronic device by direct soldering or directly fixed to the housing of the electronic device and connected to the internal substrate via a wiring connector. As an example of such a structure, there exists a thing as described in patent document 1, for example. In this example, the DC jack is directly attached to the outside of the casing of the electronic device in a detachable state to prevent disconnection on the AC adapter side.

  FIG. 3 is a plan view showing an assembled state of the DC cord connection mechanism of the electronic device which is designed to prevent the AC adapter from being disconnected. In FIG. 3, reference numeral 1 denotes a casing of a notebook personal computer, which is an electronic device, 2 denotes an internal board, and 3 denotes an internal cable that connects the internal board 2 and the jack 4. 8 is an AC adapter for supplying power, 7 is a plug, and 6 is a DC cord connecting the AC adapter 8 and the plug 7. The internal cable 3 is connected to an internal jack 10 on the internal substrate 2 by an internal plug 9 at the tip. As a result, power is supplied from the AC adapter 8 to the internal substrate 2.

  Here, if an unnecessary stress is generated when the plug 7 is removed from the DC jack 4 due to carelessness of the operator, a large force is applied to the boundary between the plug 7 and the DC cord 6 in the conventional structure. In the worst case, disconnection occurred, and in this case, the entire AC adapter was replaced, resulting in a significant increase in repair costs. In the present invention, the DC jack 4 was removed from the housing 1 as shown in FIG. Since the connection is made in a state, when the plug 7 is pulled strongly, the DC cord 6, the plug 7, and the AC adapter 8 are not affected, and a disconnection occurs between the internal cable 3 and the internal jack 9.

With the above structure, disconnection on the AC adapter side is prevented, and disconnection is performed on the DC jack side, thereby reducing the repair cost at the time of disconnection.
Japanese Patent Laid-Open No. 9-120858

  In recent years, electronic devices having portability such as notebook PCs have been reduced in weight, while the capacity of a hard disk drive (hereinafter referred to as HDD), which is a storage device attached inside, has also been increased. HDDs are susceptible to vibrations and shocks, and are more susceptible to the weight and capacity of HDDs themselves and the weight of electronic devices.

  In the configuration of the above-mentioned Patent Document 1, it is effective in reducing the repair cost at the time of disconnection, but disconnecting at the DC jack side means that an impact is easily applied to the internal jack attached to the substrate, and the substrate added at the time of disconnection The impact on the device is disadvantageous in this structure. Therefore, the impact applied to the DC jack is transmitted to the HDD inside the notebook PC via the housing and the substrate. The impact causes a malfunction of the notebook PC (Disk writing error, etc.).

  Further, in the conventional structure different from Patent Document 1, when the cord on the AC adapter side is pulled, the weight-reduced electronic device is pulled and moved together. As a result, the impact is also applied to the internal HDD, which also causes the notebook PC to malfunction. In addition, even if not careless, the cord may be pulled by the plugging / unplugging of the AC adapter that is usually performed several times a day, which may cause malfunctions in the notebook PC.

  It is an object of the present invention to reduce that an impact applied to a connector such as a DC jack is transmitted to a unit that is susceptible to vibration and impact such as an HDD inside a notebook PC.

  In order to solve the above conventional problems, the connector arrangement structure of the present invention includes an internal board of an electronic device, a connector mounted on the internal board, and an elastic body that elastically holds the connector and is attached to the internal board. It is provided.

  Alternatively, an electronic device housing, an opening provided in the electronic device housing, an elastic body that is attached to the outer periphery and holds the outer shape of the connector on the inner periphery, and is press-fitted and fixed to the elastic body Connector.

  As a result, when plugging / unplugging the AC adapter, etc., the impact on the unit that is susceptible to vibration and impact such as HDD transmitted through a connector such as a DC jack can be reduced, preventing malfunction of the notebook PC due to impact. it can.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.
