Patent Description:
Generally, a display apparatus is an apparatus that displays an image, such as a monitor and a television.

A display apparatus includes a display panel for optically displaying an image, and a rear cover for covering a rear surface of the display panel.

A cable for transmitting image or supplying power is connected to the rear case. The cable is connected to a connector, and as the connector is fastened to the rear case, the cable may be connected to the rear case.

When the cable is not fixed to the rear case, the connector may be broken as the cable is pulled toward the rear of the rear case. In order to prevent this, the cable needs to be fixed to the rear case.

In order to fix the cable to the rear case, the cable is provided with a cable holder to surround a portion of the cable, and the cable holder is fixed to the rear case by a fastening member such as a screw so that the cable may be fixed to the rear case.

In order to fix the cable to the rear case by means of a fastening member such as a screw, an instrument for assembling or disassembling the fastening member such as a screw is required. In addition, because a consumer has to directly assemble or disassemble the fastening member such as a screw using an instrument, the convenience of the consumer may be reduced, and an occurrence rate of defects or service calls may increase.

As illustrated in <FIG>, the rear case <NUM> may include the connector fastening portion <NUM> to which the connector <NUM> is fastened, and includes the cable fixing hole <NUM> into and to which a clamp <NUM> for fixing the cable <NUM> is inserted and fixed.

A cable holder <NUM> may be provided on the connector <NUM> to fix the cable <NUM> connected to the connector <NUM>. The cable holder <NUM> is provided to surround a portion of the cable <NUM>. The cable holder <NUM> may include a passing hole <NUM> through which the clamp <NUM> passes to fix the cable holder <NUM> to the rear case <NUM>. The passing hole <NUM> may be provided at a position corresponding to the cable fixing hole <NUM> of the rear case <NUM>. The cable holder <NUM> may be provided integrally with the connector <NUM>. Although not shown in the drawings, the cable holder <NUM> may be provided separately from the connector <NUM>.

The clamp <NUM> may be fixed to the cable fixing hole <NUM> by being inserted into the passing hole <NUM> of the cable holder <NUM> and the cable fixing hole <NUM> of the rear case <NUM>.

The clamp <NUM> includes a pair of fixing pins <NUM> inserted into and fixed to the cable fixing hole <NUM>, and may include a pressing part <NUM> to which a force is applied to insert the pair of fixing pins <NUM> into the cable fixing hole <NUM>, and a handle <NUM> to which a force is applied to separate the pair of fixing pins <NUM> from the cable fixing hole <NUM>.

<FIG> is a cross-sectional view illustrating that a force is applied to a pressing part in order to insert the clamp into a passing hole of the cable holder and a cable fixing hole of the rear case, <FIG> is a cross-sectional view illustrating a state in which a pair of fixing pins are elastically deformed by the clamp being inserted into the passing hole of the cable holder and the cable fixing hole of the rear case,.

<FIG> is a cross-sectional view illustrating a state in which a first hook and a second hook are fixed to the cable fixing hole according to an embodiment of the present disclosure, and <FIG> is a cross-sectional view illustrating a state in which a force is applied to a handle in order to remove the clamp from the cable fixing hole.

As illustrated in <FIG>, the clamp <NUM> includes the pair of fixing pins <NUM> inserted into and fixed to the cable fixing hole <NUM>, and may include the pressing part <NUM> to which a force is applied to insert the nair of fixing pins <NUM> into the cable fixing hole <NUM>, and the handle <NUM> to which a force is applied to separate the pair of fixing pins <NUM> from the cable fixing hole <NUM>.

The pair of fixing pins <NUM> are provided to be elastically deformable. The pair of fixing pins <NUM> include a first hook <NUM> provided at an end of one of the pair of fixing pins <NUM>, and a second hook <NUM> provided at an end of the other one of the pair of fixing pins <NUM>.

The first hook <NUM> includes a first protruding portion <NUM> provided to protrude in a radial direction of the cable fixing hole <NUM>. The first protruding portion <NUM> is fixed to the cable fixing hole <NUM> when the pair of fixing pins <NUM> are inserted into the cable fixing hole <NUM>.

The second hook <NUM> includes a second protruding portion <NUM> provided to protrude in the radial direction of the cable fixing hole <NUM>, and may include a concave portion <NUM> provided to be depressed in the radial direction of the cable fixing hole <NUM> on an opposite surface of the second protruding portion <NUM>. The second protruding portion <NUM> is fixed to the cable fixing hole <NUM> when the pair of fixing pins <NUM> are inserted into the cable fixing hole <NUM>.

In comparing the first protruding portion <NUM> of the first hook <NUM> and the second protruding portion <NUM> of the second hook <NUM>, the second protruding portion <NUM> is provided to protrude further in the radial direction of the cable fixing hole <NUM> than the first protruding portion <NUM>. By protruding the second protruding portion <NUM> more than the first protruding portion <NUM>, when the first hook <NUM> and the second hook <NUM> are fixed to the cable fixing hole <NUM>, a fixing force of the second hook <NUM> fixed to the cable fixing hole <NUM> by the second protruding portion <NUM> is greater than that of the first hook <NUM>. The fixing force may refer to a force required to release the first hook <NUM> and the second hook <NUM> from the cable fixing hole <NUM> when the first hook <NUM> and the second hook <NUM> are fixed to the cable fixing hole <NUM>.

Because the first protruding portion <NUM> of the first hook <NUM> protrudes relatively smaller than the second protruding portion <NUM> of the second hook <NUM>, when the pair of fixing pins <NUM> are inserted into and fixed to the cable fixing hole <NUM>, the pair of fixing pins <NUM> may be easily inserted and fixed.

The pair of fixing pins <NUM> may be provided to have an outer diameter equal to or smaller than inner diameters of the passing hole <NUM> and the cable fixing hole <NUM> to be easily inserted into the passing hole <NUM> of the cable holder <NUM> and the cable fixing hole <NUM> of the rear case <NUM>. The inner diameter of the passing hole <NUM> may be larger than or equal to the inner diameter of the cable fixing hole <NUM>.

The first hook <NUM> and the second hook <NUM> may protrude to have an outer diameter larger than the inner diameter of the cable fixing hole <NUM> so that the pair of fixing pins <NUM> may be fixed to the cable fixing hole <NUM> by being inserted into the passing hole <NUM> and the cable fixing hole <NUM>. That is, the first protruding portion <NUM> and the second protruding portion <NUM> may protrude to have outer diameters larger than the inner diameter of the cable fixing hole <NUM>.

Because the first protruding portion <NUM> and the second protruding portion <NUM> may protrude to have the outer diameters larger than the inner diameter of the cable fixing hole <NUM>, when the pair of fixing pins <NUM> is inserted into the cable fixing hole <NUM>, the pair of fixing pins <NUM> may be elastically deformed so that the outer diameters of the first hook <NUM> and the second hook <NUM> decrease. After the first hook <NUM> and the second hook <NUM> are fully inserted and pass through the cable fixing hole <NUM>, the first hook <NUM> and the second hook <NUM> may be elastically deformed to return to the original outer diameter. When the first hook <NUM> and the second hook <NUM> are elastically deformed to return to the original outer diameters, the first protruding portion <NUM> and the second protruding portion <NUM> may be fixed to the cable fixing hole <NUM>.

The pressing part <NUM> may be provided above the pair of fixing pins <NUM>. When the pair of fixing pins <NUM> are inserted into the cable fixing hole <NUM>, a force is applied to an upper end of the pressing part <NUM> in a direction in which the pair of fixing pins <NUM> are inserted into the cable fixing hole <NUM>.

The handle <NUM> may be provided to extend from one side of the pressing part <NUM> adjacent to the first hook <NUM> in the first hook <NUM> and the second hook <NUM>. When the pair of fixing pins <NUM> are separated from the cable fixing hole <NUM>, a force is applied to a lower end of the handle <NUM> in a direction in which the pair of fixing pins <NUM> are separated from the cable fixing hole <NUM>. The reason that the handle <NUM> extends from one side of the pressing part <NUM> adjacent to the first hook <NUM> is that the first hook <NUM> may be released from the cable fixing hole <NUM> with a smaller force than the second hook <NUM>. In addition, this is to cause more elastic deformation to occur in the second hook <NUM> than in the first hook <NUM> in order to easily release the second hook <NUM> which requires a great force to be released from the cable fixing hole <NUM>.

Hereinafter, an operation of fixing or releasing the cable <NUM> by the clamp <NUM> will be described in detail.

As illustrated in <FIG>, in order to fix the cable <NUM> to the rear case <NUM>, first, the clamp <NUM> may be positioned above the passing hole <NUM> and the case fixing hole <NUM>. In a state in which the clamp <NUM> is positioned above the passing hole <NUM> and the case fixing hole <NUM>, a user may press the upper end of the pressing part <NUM>.

When a force is applied to the upper end of the pressing part <NUM> by pressing the upper end of the pressing part <NUM> in the direction in which the pair of fixing pins <NUM> are inserted into the cable fixing hole <NUM>, as illustrated in <FIG>, the first hook <NUM> and the second hook <NUM> may be inserted into the passing hole <NUM> and the cable fixing hole <NUM> by being elastically deformed so that the outer diameters thereof decrease. When the first hook <NUM> and the second hook <NUM> are inserted into the passing hole <NUM> and the cable fixing hole <NUM>, the first protruding portion <NUM> and the second protruding portion <NUM> may come into contact with inner walls of the passing hole <NUM> and the cable fixing hole <NUM>. In this case, the force applied to the pressing part <NUM> may be substantially <NUM> kgf.

When the force is continuously applied to the pressing part <NUM>, as illustrated in <FIG>, the first hook <NUM> and the second hook <NUM> may pass through the cable fixing hole <NUM>. When the first hook <NUM> and the second hook <NUM> pass through the cable fixing hole <NUM>, the first protruding portion <NUM> and the second protruding portion <NUM> may not be in contact with the inner walls of the passing hole <NUM> and the cable fixing hole <NUM>. When the first protruding portion <NUM> and the second protruding portion <NUM> are not in contact with the inner walls of the passing hole <NUM> and the cable fixing hole <NUM>, the first hook <NUM> and the second hook <NUM> may be elastically deformed so that the outer diameters thereof increase as much as the original outer diameters. When the first hook <NUM> and the second hook <NUM> are elastically deformed so that the outer diameters thereof increase, the first protruding portion <NUM> and the second protruding portion <NUM> may be fixed to the cable fixing hole <NUM>. At this time, because the second protruding portion <NUM> protrudes relatively more than the first protruding portion <NUM>, the fixing force of the clamp <NUM> may increase. In this case, the fixing force may be substantially <NUM> kgf. As the fixing force of the clamp <NUM> increases, even when the cable <NUM> is pulled, the clamp <NUM> may not be easily separated. Accordingly, the cable <NUM> may be maintained in a state of being fixed to the rear case <NUM>.

In order to separate the clamp <NUM> from the cable fixing hole <NUM>, as illustrated in <FIG>, the user may raise the handle <NUM>. When the user raises the handle <NUM>, a force may be applied to the lower end of the handle <NUM> in the direction in which the pair of fixing pins <NUM> are separated from the cable fixing hole <NUM>. When a force is applied to the handle <NUM>, as the first hook <NUM> adjacent to the handle <NUM> is elastically deformed, the first protruding portion <NUM> may be easily released from the cable fixing hole <NUM>.

When the first hook <NUM> is released from the cable fixing hole <NUM> by being elastically deformed, the second hook <NUM> may be elastically deformed so that the concave portion <NUM> may move to a position for receiving an opposite surface of the first protruding portion <NUM> of the first hook <NUM>. When the second hook <NUM> is elastically deformed, the second protruding portion <NUM> may be released from the cable fixing hole <NUM>.
