The present invention relates to a socket structure, more particularly to the socket having a clamp plate to avoid possible cracks of the printed circuit board (PCB) caused by unexpected movement of the plug inside the socket.
Recently, 3C products (communication, computer and consumer electronics) have already played important roles in daily life. In particular, the new emerging flat panel display that features less space occupation has quickly grasped people's attention and interests and is extending its market share over the traditional cathode ray tube displays.
In the flat panel display industry, the liquid crystal display (LCD) is one of the well-developed products. The LCD has merits of lightweight, convenient moving and less space occupation and is widely applied to cell phones, language translators, digital cameras, PDAs and notebook computers.

A side plate lateral to the PCB 110 (may be a part of the housing of the PCB) can provide a plurality of holes to mount relevant sockets for the LCD. In

To further fix the power socket 11 on the PCB 110, a fixed iron piece 112 is used to restrain the socket 11 by screwing to the PCB 110 through the combining holes 1130 at the opposing extending portions 113 of the fixed iron piece 112.
As shown in
Therefore, when the plug 14 engages with the socket 11, the welding between the socket 11 and the PCB 110 needs to sustain a substantial pulling force from the plug's action. In some accidental situations, the pulling force may be large enough to crack the welding between the socket 11 and the PCB 110 that may finally lead to fail the connection to the power source and the imaging of the flat panel display. Further, for the extend portion 113 of the fixed iron piece 112 is fixed firmly on the PCB 110, a room on the PCB 110 must be empty, and thus wasted, to dodge the fixed iron piece 112.

For ensuring the socket 21 on the PCB 210, a conventional back-housing 26 of the panel display is used to press on top of the socket 21. As shown in
The side plate 25 of the housing of the PCB can provide a plurality of combining holes to expose the socket 21 of the PCB 210. As shown in
In addition, with respect to the retrieval force through the plug, the direction arrangement of the ribs is not good for structural stability. In particular, the socket may fall off from the housing after frequently usage. Besides, when the plug is anchored inside the socket, the welding between the socket and the PCB needs to sustain the disturbance force from the plug. So, any accidental force upon the socket or the plug may be easily to crack the welding between the socket and the PCB. Definitely, any crack to the welding may interrupt the power source to the flat panel display.
The object of the present invention is to provide a fixed seat of the socket firmly holding the socket on the PCB so as to avoid the pulling force of the plug to crack the PCB.
The another object of the present invention is to provide a flat panel display having the fixed seat of the socket, and the fixed seat can avoid any movement between the socket and the PCB pulling out of the plug.
The fixed seat of the socket of the present invention is applied to a panel display device. One side face of the socket has a flange. The fixed seat comprises a side plate and a clamp plate. The side plate has a combining hole for the socket to receive an external plug. The flange of the socket is fixed onto the side plate of the fixed seat.
In a preferred embodiment, the combining hole is an opening gap and the clamp plate is combined to the combining hole for holding the side plate. In another embodiment, the combining hole is formed as a seal gap.
In a preferred embodiment, an end of the socket having a combining hole to receive a plug, and another end of the socket is electrically connected to a PCB by welds or screws.
In a preferred embodiment, the clamp plate comprises an inner clamp plate and an outer clamp plate spaced from the inner clamp plate so as to clamp the side plate in between. Each side of the combining hole has a trough to engage, by screws or the like, a respective hook of the clamp plate.
In another preferred embodiment, a flat panel display having a fixed seat of a socket comprises a panel display, a PCB, a socket and a fixed seat. The PCB is connected to the panel display. An end of the socket is connected to the PCB, and a side face of the socket has a flange. The fixed seat comprises a side plate and a clamp plate. The side plate has a combining hole, and the clamp plate clips the side plate so as to have the socket fixed on the side plate.

The object of the present invention is to provide a fixed seat of the socket for avoiding any relative movement of the socket with respect the side plate while the socket meets a pull-out or push-in of an external plug.
The fixed seat applicable to the flat panel display or other display device is set to a side plate of the corresponding display device so as to protect welds between the socket and the PCB from being cracked by applications upon the plug.

An end of the socket 31 is connected to the PCB 310, and one side of the socket 31 has a socket hole 311 for receiving the plug 34. A bottom face of the socket 31 has a plurality of welding 3102 to pair respectively a plurality of pads of the PCB 310 (not shown in the figure). The socket 31 is fixed and thus electrically connected to the PCB 310 by welding. In addition, the socket 31 can be further surely fixed onto the PCB 310 by screwing.
A flange 312 of the socket 31 is included at a side of the socket 31 facing the plug 34. As shown in

The clamp plate 36 of the present invention comprises an inner clamp plate 361 and an outer clamp plate 362. By providing the spacing between the inner clamp plate 361 and the outer clamp plate 362 as clearly shown in
In this preferred embodiment, the top of clamp plate 36 further comprises an extended face 363 which is perpendicular to both the inner clamp plate 361 and the outer clamp plate 362. The extended face 363 extends horizontally to act as a part to integrate the clamp plate 35 to the panel display. The clamp plate 36 can be made of a plastics or an iron material.
By providing the fixed seat of the socket in accordance with the present invention, drawbacks of the conventional technology in cracking the PCB and the bottom welding of the socket have been improved. With the introduction of the clamp plate in the present invention, the side plate and the socket can be firmly engaged, and the force from removing the plug can be fully taken by the side plate without being transmitted further to crack possibly the PCB.
