Referring to fig. 1, the present embodiment provides a television housing 100 including a rear cover 10, a PCB control board 20, and a logic board 30. The rear cover 10 mainly serves as a load bearing member for supporting and mounting the PCB control board 20 and the logic board 30. The PCB control board 20 is a main control board of the whole television. The logic board 30 may be a screen driving board, a central control board, a T-CON board (Timing Controller, timing control circuit), and the like, and the logic board 30 is configured to convert LVDS image data input signals (input signals include RGB data signals, clock signals, and control signals) transmitted by the PCB control board 20 into LVDS signals (Low Voltage Differential Signaling) capable of driving the liquid crystal screen after being processed by the logic board 30, and then directly send the LVDS signals to the LVDS receiving chip of the liquid crystal screen to drive the liquid crystal screen to display images.

Specifically, the rear cover 10 includes a rear cover body 11 and a bezel 12 provided around an outer edge of the rear cover body 11. The rear cover body 11 is made of an insulating material, for example, the rear cover body 11 may be made of polypropylene, polyurethane, polycarbonate, polymethyl methacrylate, polystyrene, polybutylene terephthalate, or the like.

The bezel 12 includes an insulating frame portion 121 and a conductive frame portion 122. It is understood that the insulating frame portion 121 is a non-conductive portion of the bezel 12. The insulating frame portion 121 may be disposed at the outer edge of the rear cover body 11 in an adjustable manner according to actual manufacturing requirements to control the manufacturing cost, and the material of the insulating frame portion 121 may be the same as the material of the rear cover body 11, for example, the material of the insulating frame portion 121 may be polypropylene, polyurethane, polycarbonate, polymethyl methacrylate, polystyrene, polybutylene terephthalate, and the like. Of course, the material of the insulating frame portion 121 may be different from that of the rear cover body 11. The conductive frame portion 122 is a conductive portion in the frame 12 for meeting the requirement of grounding. The conductive frame portion 122 may be made of a galvanized plate, an aluminum alloy plate, or the like. Similarly, the position of the conductive frame 122 can be adjusted according to actual needs.

For example, the insulating frame portion 121 encloses all the external parts of the rear cover body 11, and the conductive frame portion 122 is disposed on one of the insulating frame portions 121, so that the manufacturing efficiency of the entire rear cover 10 is more uniform, the rear cover body 11 and the insulating frame portion 121 can be integrally molded, and the manufacturing process is less and simpler.

Alternatively, for example, the insulating frame 121 encloses most of the exterior of the rear cover body 11, for example, if the rear cover body 11 has a square structure, the insulating frame 121 may alternatively enclose three outer edges of the rear cover body 11, or even a fourth outer edge, and the reserved exterior is used for the conductive frame 122 to mount.

The shape and structure of the insulating frame portion 121 and the conductive frame portion 122 are not limited, and both may have the same shape and structure, for example, the insulating frame portion 121 and the conductive frame portion 122 are both strip-shaped structures or plate-shaped structures. Of course, the shape and structure of the insulating frame and the conductive frame 122 may be the same, for example, the insulating frame 121 may have a strip structure or a plate structure, and the conductive frame 122 may have a sheet structure or a block structure.

The PCB control board 20 is disposed on the rear cover body 11, and the logic board 30 is disposed on the conductive frame portion 122. It is to be understood that the PCB control board 20 may be detachably coupled with the rear cover body 11 by fasteners such as screws. The logic board 30 is electrically connected to the conductive frame portion 122 to satisfy the grounding requirement. For example, the logic board 30 may be welded to the conductive frame portion 122, or may be sequentially inserted through the bare copper portion of the logic board 30 and the conductive frame portion 122 by screws.

The PCB control board 20 is electrically connected to the logic board 30. Here, the PCB control board 20 is electrically connected to the conductive frame portion 122 through the logic board 30 to achieve grounding. The PCB control board 20 and the logic board 30 may be connected by conductive members such as wires or conductive paste.

The utility model provides a TV set casing 100, its back lid 10 includes back lid body 11 and frame 12, and wherein, back lid body 11 is insulating, and frame 12 includes insulating frame portion 121 and electrically conductive frame portion 122, and promptly, frame 12 has insulating and electrically conductive two kinds of characteristics, can enough reduce manufacturing cost, can satisfy the ground connection requirement again. Meanwhile, the PCB control board 20 can bear more electromagnetic compatibility margin of the whole television, and is electrically connected to the logic board 30 to connect with the conductive frame portion 122 of the frame 12 of the rear cover 10, so as to achieve grounding. Thus, the television set housing 100 of the present application can improve the probability that the entire television set passes the electromagnetic compatibility test.

Referring to fig. 2, in an embodiment, the rear cover body 11 is a square structure, the rear cover body 11 has four outer edges, the insulating frame 121 surrounds each outer edge, and the conductive frame 122 is disposed on one of the insulating frames 121. It is understood that the rear cover body 11 is a square cover plate, so that the cover plate has four straight outer edges, and the insulating frame portions 121 enclose the outer edges to form a closed structure, and the conductive frame portion 122 is selectively disposed on one of the insulating frame portions 121. For example, the conductive frame portion 122 may be directly mounted on the side of the insulating frame portion 121 facing the rear cover body 11; alternatively, the insulating frame portion 121 is provided with a mounting hole, and the conductive frame portion 122 is fixed to the mounting hole.

Alternatively, referring to fig. 3, in an embodiment, the rear cover body 11 is a square structure, the rear cover body 11 has four outer edge portions, the insulating frame portion 121 surrounds three of the outer edge portions, and the conductive frame portion 122 surrounds the remaining outer edge portions. Similarly, the rear cover body 11 is a square cover plate, and thus the cover plate has four straight outer edges, in contrast, in the present embodiment, the insulating frame portion 121 encloses a portion of the outer edge thereof, and forms an open structure, and the conductive frame portion 122 is disposed at the gap of the insulating frame portion 121, which is the open structure, so that the frame 12 is a more closed structure.

Of course, in other embodiments, the insulating frame portion 121 may also surround two outer edge portions of the rear cover body 11, and the conductive frame portion 122 surrounds the remaining outer edge portions, so as to form a closed frame 12 structure.

Similarly, in some embodiments, the rear cover body 11 may have other shapes and structures, such as a circular shape or an arc shape, so that the outer edge of the rear cover body 11 only needs to be surrounded by the insulating frame 121 and the conductive frame 122.

In one embodiment, the length of the conductive frame portion 122 is less than the length of the outer edge portion. It can be understood that, when the insulating frame portion 121 has the open structure after enclosing the rear cover body 11, the conductive frame portion 122 encloses the gap of the insulating frame portion 121 having the open structure, and particularly, the rear cover body 11 is a square cover plate, then, for further saving the manufacturing cost, the length of the conductive frame portion 122 may be selected to be smaller than the length of the outer edge portion, so as to reduce the material usage of the conductive portion in the frame 12.

Referring to fig. 1, in one embodiment, the PCB control board 20 has two ground interfaces 21, and the logic board 30 is provided with a first exposed portion 31 connected to the corresponding ground interface 21. It can be understood that the two grounding interfaces 21 are the anode grounding interface 21 and the cathode grounding interface 21, respectively, and form a grounding loop with the two first exposed portions 31 of the logic board 30, so that the electromagnetic compatibility of the PCB control board 20 is improved, that is, the electromagnetic compatibility of other electronic components of the whole television is reduced.

Illustratively, as shown in fig. 1, the ground interface 21 is a ground hole, and the hole wall of the ground hole is an exposed metal portion, so that the logic board 30 can be electrically connected by plugging. In addition, two ground holes are distributed on the edge of the PCB control board 20 to avoid other electrical elements on the PCB control board 20, thereby improving the use safety of the whole PCB control board.

Specifically, referring to fig. 1, in one embodiment, the tv housing 100 includes a conductive member 50, and the conductive member 50 is used for connecting the grounding interface 21 and the first exposed portion 31. It is understood that the conductive member 50 may be a wire, one end of which is connected to the grounding interface 21 and the other end of which is connected to the first exposed portion 31. For example, the grounding interface 21 is a grounding hole, and when the first exposed portion 31 is a bare copper portion, one end of the wire is provided with an insertion column, the insertion column is adapted to the grounding hole, and the other end thereof can be welded and connected to the bare copper portion.

Referring to fig. 1, in an embodiment, the end surface of the PCB control board 20 facing the rear cover body 11 is provided with a second exposed portion 22, the television housing 100 further includes a conductive sheet 40, the conductive sheet 40 is attached on the second exposed portion 22 and extends to the outside of the PCB control board 20, and the conductive sheet 40 is electrically connected to the interface of the logic board 30. It will be appreciated that in order to reduce the contact resistance of the PCB, the conductive sheet 40 may be directly attached to the second exposed portion 22 to increase the electrical contact area therebetween, thereby reducing the contact resistance therebetween. Furthermore, the conductive sheet 40 may be directly electrically connected to the interface of the logic board 30, that is, one end of the conductive sheet 40 away from the second exposed portion 22 is directly attached to the interface of the logic board 30. Alternatively, the conductive sheet 40 may be connected to the interface of the logic board 30 by a wire.

Referring to fig. 1 and 4, in an embodiment, the conductive sheet 40 includes a supporting layer 41 and a conductive layer 42 stacked together, the supporting layer 41 is supported by the back cover body 11, and the conductive layer 42 is attached to the second exposed portion 22. It can be understood that the supporting layer 41 is used to fill the distance between the second exposed portion 22 and the inner wall of the rear cover body 11, so as to prevent the conductive sheet 40 from being suspended as a whole, and reduce the connection strength between the conductive sheet and the second exposed portion 22. The conductive layer 42 is directly electrically connected to the second exposed portion 22, and the connection method can be selected from adhesion, soldering, and the like.

For example, the supporting layer 41 is made of a foam material, and has elasticity in the thickness direction, and one end of the supporting layer 41 away from the conductive layer 42 has viscosity, so that the supporting layer can be directly attached to the inner wall of the rear cover body 11.

Alternatively, the support layer 41 may be made of metal, and a screw hole may be formed in the support layer 41 and connected to the rear cover body 11 by a fastener such as a screw.

The embodiment of the present application further provides a television, which includes the television housing 100 described above.
