Circuit board flat cable detection device and detection method

Abstract

The invention relates to a circuit board flat cable detection device and method, and the device comprises a signal output module, an output terminal, a signal receiving module, a detection seat, a detection result output module and a power supply, the detection seat comprises a housing, the upper end of the housing is provided with a detection port, the housing is internally provided with an insulation pedestal, and a plurality of probes are vertically inserted in the pedestal. The upper end of each probe extends out of the detection port, positioning pins are respectively arranged on the upper surface of the shell at two ends of the detection port, the lower end of each probe is electrically connected with the signal receiving and comparing module, the detection seat is detachably connected with a detection clamp, and the detection clamp comprises a base and a gland. A plurality of grooves matched with the outer contour of the circuit board are formed in the base, a through hole is formed in each groove, flat cable connecting points are all right opposite to the through holes when the circuit board is embedded into the grooves, protruding blocks are arranged on the pressing cover, and when the pressing cover and the base are oppositely combined, the top portions of the protruding blocks are partially inserted into the corresponding grooves. Positioning holes corresponding to the positioning pins are formed in the base and the gland.

Description

technical field [0001] The invention relates to a circuit board wiring detection device and a detection method. Background technique [0002] The cable on the circuit board is generally formed by a plurality of wires arranged and welded on the circuit board. Each wire transmits a different signal. The end of the cable away from the circuit board will be made into a terminal. The position of each wire on the terminal is Fixed, so the order of the wiring (that is, the order in which each wire is connected to the circuit board) is wrong will cause signal transmission errors, resulting in the function of the circuit board cannot be realized normally, so the circuit board needs to be corrected after connecting the wiring. Check the wiring to ensure that the board can be used normally. [0003] The conventional method of detecting circuit board wiring is to pre-install the soldered circuit board on an analog device, and then check whether the functions of the circuit board can op...

AI Technical Summary

Problems solved by technology

In this detection method, the detection engineering is relatively cumbersome, and each function of the circuit board needs to be tried, so the detection efficiency is low, and the soldered circuit board needs to be used for detection. When a problem is detected, the repair cycle is long and the cost is high.

[0004] To sum up, the current conventional method of detecting circuit board wiring has the advantages of cumbersome detection process, low detection efficiency, long repair cycle and high repair cost for circuit boards with quality problems.
