Abstract

The internal weak current line and outer leading line are configurated in partition on the printed plate component with composite structure to insert every components into left and right rear panel of printed circuit plate in machine box in order vertically. The weak current line on every components are connected each other by printed lines at rear panel of printed circuit plate, the outer leading line of every components are insert in direct leading-out socket fixed on machine box to lead lines out directly. The confounding between strong and weak current liens and leading line is prevented and the separation of diffeent electric lines is realized by said invention with excellent anti-interference ability.

Description

technical field

[0001] The invention relates to a printed circuit board plug-in structure in the electrical field, in particular to a combined plug-in structure composed of an anti-interference circuit board plug-in. Background technique

[0002] At present, in each microcomputer control device, especially in the relay protection device of the engine, it is a relatively common problem that the strong electric signal is serially inserted into the weak electric circuit to interfere with the normal operation of the device. For this reason, in conventional devices, measures such as isolation and filtering have been adopted, which have produced certain positive effects, but the effects are not very satisfactory. Research has shown that the source of interference is mainly the surge (analog quantity) introduced from the outside through the device terminals. input, digital input, output, DC power input, etc.). However, in the existing device, the chassis structure and terminal arr...

Embodiment Construction

[0012] figure 1 Among them, the virtual box A on the upper part of the printed circuit board insert 1 is shown as an internal weak current circuit. Corresponding to this circuit, a plug 2 of the circuit is fixedly arranged at the inserting part of the printed circuit board insert 1 . In the lower virtual frame B of the printed circuit board insert 1, the external incoming and outgoing lines are indicated. Corresponding to this circuit, another plug 3 is also fixedly arranged on the printed circuit board insert.

[0013] figure 2 Among them, take a relay protection device as an example, each printed circuit board plug-in such as CPU plug-in, open-in and open-out plug-in, man-machine dialogue plug-in (MMI), communication port, power plug-in and so on. The weak current lines of each plug-in are connected by the weak current connection lines shown in the upper part of the figure, while the external outgoing lines are separated from the weak current lines and weak current connect...
