Problems solved by technology
[0004] In addition, the electrical conduction between the TV signal transmission connector 110 or the AV terminal socket 12 and the fixed iron plate 13 will be completed by pasting aluminum foil and conductive foam (not shown in the figure), which will make the appearance and texture of the product worse and reduce the The value of the product and the limitation of space distance often cause the aluminum foil and conductive foam fixed by the adhesive method to fall and be damaged, and the quality of the adhesive also directly affects the grounding characteristics, and it is difficult to control the quality of anti-noise
[0005] Moreover, directly switch to manual spot welding (not shown in the figure) to complete the electrical conduction between the TV signal transmission joint 110 or the AV terminal socket 12 and the fixed iron sheet 13, although the TV signal transmission joint 110 or the AV terminal socket 12 can be made The contact method between the terminal socket 12 and the fixed iron plate 13 is better than that of aluminum foil, but the appearance quality is also affected, and it also lengthens the working hours and affects the production process cost of the product.

A method for assembling expansion card with elastic fixing device includes assembling metal elastic conductive unit between signal transmission connector socket and fixing plate, then fixing the circuit board on fixing plate, having wriggle section along the first direction on metal elastic conductive unit for generating telescopic elasticity along the first direction to go against between said socket and said fixing plate for finalizing electric ¿C connection through. The expansion card device is also disclosed.
Description
technical field [0001] The invention relates to an expansion card device using an elastic fixing device and an assembly method for the expansion card device, especially an expansion card device using an elastic fixing device and an assembly method for the expansion card device in a computer system. Background technique [0002] See figure 1 , which is a schematic diagram of the appearance of a common TV expansion card 1, which mainly has two groups of input and output terminals, the first group belongs to the TV signal transmission connector 110 (generally called RF connector) on the channel selector (tuner) 11, and the second group Two groups are AV terminal sockets 12 (generally called RCA connectors) belonging to a group of common three, which can be used for connecting the left and right audio and video signal lines (not shown in this figure). [0003] And in order to comply with the requirements of the three major environmental protection directives (WEEE, RoHS, EUP) o...
