Embodiment

[0025] In order to clearly describe the implementation method of the protection circuit for preventing incorrect connection of connectors, the circuit system of a liquid crystal television is taken as an example. Since the liquid crystal screen accounts for more than 50% of the cost of the whole machine, it has high practical significance.

[0026] At present, there are two or more manufacturers or models of LCD screens used in LCD TVs of the same type. The input parts of the drive parts of these different manufacturers or models of LCD screens are basically the same, and the difference is the voltage Vpp supplied to the LCD screen drive circuit. For example, the voltage of the LCD screen produced by L company is 12V; while the voltage of the LCD screen produced by C company is 5V. Therefore, if the circuit components of the LCD screen produced by Company L are mistakenly connected to the LCD screen produced by Company C during the production or maintenance process, the LCD sc...

Abstract

The invention is concerned with circuit control process by affording a kind of circuit system to prevent the error connecting of linker. The circuit connects or not connects with insulated lead between some two tube feet of wiring harness pin to linker according to the different of wiring harness and the circuit of circuit module. Add control circuit GA and switch KA in the circuit system Sa and add control circuit GB and switch KB in the circuit system Sb. Because the work theory of control circuit GA and GB is different, so the connecting modules are not matching with each other, it will make out different respond by controlling switch KA or KB. The great effect is that the circuit system can judge out at once to cut off the wrong signal leading foot to prevent the breakage when circuit modules of different circuit system are mixed using.

Description

technical field [0001] The invention relates to circuit control technology. Background technique [0002] The circuit system Sa is composed of a circuit assembly A1 and a circuit assembly A2, and the circuit assembly A1 and the circuit assembly A2 are connected through a connector A with a cable X. Connector A is formed by mating socket A and plug A. The pins of the plug A and the socket A transmit signals through the insulated wires in the cable X according to a specific corresponding relationship, that is, the circuit component A1 transmits signals to the circuit component A2 through the cable X of the above-mentioned connector. The connector includes n pins. When the plug A is matched with the socket A, the first pin P1 of the plug must be connected to the first pin P1 of the socket, and the second pin P2 of the plug is connected to the second pin P2 of the socket... , the nth pin Pn of the plug is connected with the nth pin Pn of the socket. [0003] Another circuit s...
