Embodiment Construction

[0026] Such as figure 1As shown, the level generator, the waveform generator, the high voltage generator, and the positive electrode of the aging power supply are respectively connected to the four selection terminals of the first function selection switch K1. The common end of the first function selector switch is connected with eight first detection switches K2, and each first detection switch is respectively connected to one end of the eight-core wire to be detected by the first socket A. The other end of the wire to be tested is correspondingly connected to the eight second detection switches K4 through the second socket B. The other end of the second detection switch is connected together and then connected with the common end of the second function selection switch K3; Negative connection.

[0027] Insulation requirements for cable processing to be inspected: 5 megohms, 1000V; on-resistance less than 5 ohms; aging requirements: 2A for 1 hour; high level is defined as 1...

Abstract

The invention discloses a cable detection board, a cable detection method, and line sequence, impedance, insulation and aging detection methods. The cable detection board comprises N first detection switches. The output end of each first detection switch is connected with the input end of a second detection switch through a to-be-detected cable. The input ends of the N first detection switches are connected with at least one first function selection switch. The output end of the N second detection switches are connected with at least one second function selection switch. The problem that the line sequence is difficult to detect in the prior art is solved. The cable detection board and the detection methods have the advantages of comprehensive test parameters, low cost, low requirement on light source, line color and terminal type, wide application scope, simple wiring, and easy operation.

Description

technical field [0001] The invention relates to a board card, in particular to a cable detection board and method, line sequence, impedance, insulation and aging detection method. Background technique [0002] During cable processing, wires of different colors in the cable need to be inserted into the corresponding holes of the terminal in a certain order (determined by the cable processing requirements). Manual insertion of terminal wires, miswiring or wrong line sequence are unavoidable problems. In order to solve the problem that the wire sequence is difficult to detect in wire harness processing, the existing solution is to use a high-definition camera to sample the wire harness picture, identify the color and position of the wire sequence through an image analysis algorithm, and locate the wire sequence according to the color matching relationship. This solution has a single test parameter and low cost. High cost, high requirements on light source, wire color, and term...
