Embodiment Construction

[0019] In the following, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known processing steps have not been described in detail.

[0020] like figure 1 As shown, it includes an upper shell 1, a PCB circuit board 2, a decoder 3, a USB socket 4, a shockproof assembly 5, an upper layer of cushioning cotton 501, including a shell, and a lower layer of cushioning cotton 502. The shockproof assembly 5 is located on the PCB The upper and lower sides of the circuit board 2 are connected by buckles. The '7' type support column is located at the four corners of the PCB circuit board 2, and the two are connected by welding. The upper cushioning cotton 501 is located directly above the PCB circuit board 2 , its shape is a ...

Abstract

The invention discloses a TV stick. The TV stick comprises a housing, a PCB, a decoder and a USB interface, and further comprises shockproof assemblies which are arranged on the upper side and the lower side of the PCB and connected with each other in a buckled manner. Memory cotton is arranged on the upper side and the lower side of the PCB of the TV stick, so that the excellent shockproof effect is provided; 7-shaped supporting posts at four corners of the PCB are connected with through holes in four corners of the upper-layer memory cotton in a buckled manner; through a groove I in the center of the upper-layer memory cotton, a component on the PCB is free of impact; through heat dissipation holes in the groove, heat generated when the PCB works can be radiated smoothly; the memory cotton is also arranged at the lower layer of the PCB; and a 3-5 mm groove II is formed in the center of the lower-layer memory cotton, and the PCB is positioned in the groove II, so that the PCB is in a double-layer protection mode, and has an excellent heat radiation function. Therefore, the TV stick has an excellent shockproof property.

Description

technical field [0001] The invention relates to a signal receiving and converting device, in particular to a TV stick. Background technique [0002] Existing TV sticks are generally composed of housings, PCB circuit boards, decoders, and USB sockets. The working environment of TV sticks is generally located on family TVs, office computers, and mobile notebooks. The volume is small, and the use method is plug-in, so it is very easy to collide, squeeze and drop during the placement process. These situations will cause damage to the internal electronic components of the TV stick, making the TV stick scrapped in advance, and seriously affecting its service life. In view of above-mentioned defective, be necessary to design a kind of TV stick really. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a TV stick to solve the problem of damage to electronic components inside the TV stick due to collision, extrusion and dro...
