A split plug-in functional conversion interface

Abstract

The invention discloses a split plug-in functional conversion interface, belonging to the field of conversion interfaces, which includes a circuit main board, an upper-level access terminal connected to the line input end of the circuit main board, and a lower-level connection terminal connected to the circuit main board line output end. terminal, the upper-level access terminal includes a line connection board and a connection wire, the line input end of the line connection board is connected to the connection wire, and the line output end of the line connection is connected with a golden finger; fixedly installed on the circuit main board There is a plug connector connected with the line input end, and the plug connector is mated with the golden finger. The invention has the effect that the conversion interface can meet the normal use requirement without directly welding the circuit board in the conversion interface and the connecting wire in the upper-level access terminal.

Description

technical field [0001] The invention relates to the technical field of conversion interfaces, in particular to a split plug-in functional conversion interface. Background technique [0002] In the electronics industry, data information conversion between different interface types, such as VGA interface, DVI interface, HDMI interface, DP interface, etc., needs to be realized through conversion interfaces with different functions. As attached to the manual Figure 4 As shown, the conversion interface in the prior art includes a functional circuit board 1 and a coaxial cable 22 inside, and each terminal of the coaxial cable 22 is usually welded on the pads of the input ends of the lines on both sides of the circuit board 1 , which is simple and fast, without the need to design other connection methods, and at the same time can achieve a reliable connection between the two. [0003] However, there are the following problems in the connection between the coaxial line and the cir...

Problems solved by technology

[0003] However, there are the following problems in the connection between the coaxial line and the circuit board by welding: 1. Usually the board of the circuit board is relatively large, and the board is full of electronic components when it is not welded, so the production cost is high, and welding is inevitable. There will be bad phenomena such as virtual welding, false welding, and desoldering. After repeated welding or misoperation, the pads on the entire circuit board will easily fall off, and the entire circuit board will be directly scrapped; 2. Coaxial cables must be welded synchronously On the circuit board, that is, the welding process can only be formed into a finished conversion interface product after the processing of the coaxial line and the circuit board is completed, and it is also easy to fall off between the two during the process of transferring the conversion interface to the factory
