Description

Contact detection device for failure analysis of automobile production line Technical Field The utility model relates to the technical field of line detection jigs, in particular to a contact detection device for failure analysis of an automobile production line. Background Wire failure is commonly referred to in automotive production lines as a problem with wire harnesses or wire connections, resulting in circuit interruption or poor signal transmission. Such problems may be caused by various reasons, such as poor contact, wear, breakage, etc. The wire failure can directly affect the performance and safety of the automobile, and can cause problems such as functional failure, signal transmission errors or circuit short circuit. At present, a universal meter is matched with a wire and a crocodile clip to be a common contact detection tool fixture for line failure analysis in an automobile production line. At present, china patent discloses an automobile line detector (the authorized bulletin number is CN 206594248U), when the device is used for detecting the voltage of a power supply loop, a probe is connected with a detection terminal of electric equipment, a clamping end is connected with the negative electrode of a storage battery, at the moment, the power supply loop forms a closed loop through the detector, a detector toggles a selection switch to select a shunt resistor similar to the electric equipment, a voltage value displayed in a display screen is read, if the read value is the power supply voltage, the normal operation of the power supply loop is indicated, if the read value is lower than the power supply voltage but greater than 0v, the virtual connection fault exists in the power supply loop, and if the read value is 0v, the disconnection of the power supply loop is indicated, whether the virtual connection or the disconnection phenomenon occurs in the power supply loop can be accurately judged.
