Automobile conducting wire single-node fault setting device and method

Abstract

The invention discloses an automobile conducting wire single-node fault setting device and method. The device comprises a shell, an internal PCB, resistors, micro manual switches and fastening bolts,wherein the shell is provided with wiring holes and bolt holes, the resistors and the micro manual switches are both mounted on the internal PCB to form a circuit, one micro manual switch forms a normal state circuit, the rest n micro manual switches are connected in series with the corresponding resistors to form a virtual connection circuit in a multi-fault state, the normal-state circuit and the virtual connection circuit in the multi-fault state are connected in parallel, and wire cores at two cut-off openings of an automobile conducting wire needing to be connected into the device are inserted into the wiring holes, pressed by the fastening bolts screwed into the bolt holes and electrically connected to the line of the internal PCB. According to the invention, a single automobile conducting wire can be rapidly, firmly and reliably connected in series, the fault setting is convenient and flexible, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of automobile electrical fault setting, in particular to a single-node fault setting device and method for automobile wires. Background technique [0002] In vehicle fault diagnosis teaching and actual auto repair, fault simulation (on, off, and virtual faults) is often carried out with the help of fault setting equipment of automobile routes. The existing fault setting devices of automobile circuits can basically be divided into two types: temporary and fixed: (1) Temporary fault setting equipment refers to the series connection of switches or resistors in the car line. The operation process is as follows: cut off the target wire on the car → peel off the wire at the break → connect a resistor or switch in series at the break (soldering is required to Ensure that there is no virtual connection at the series connection / joint connection) → insulation treatment at the connection point. This fault setting meth...

Problems solved by technology

[0003] However, there are still deficiencies in the above two setting devices

For temporary fault setting equipment, its fault setting is time-consuming and labor-intensive, and it is easy to generate unnecessary fault points (false connections are likely to occur at the barge), and if the insulation treatment is not up to standard, it is prone to short circuit and damage to vehicle components. Poor reliability and inefficiency; and when setting the fault point, it is impossible to realize the switching of multiple fault states by connecting the fault setting objects in series with a single node at one time, and the fault setting mode is single

For fixed fault setting equipment, its cost is high, its volume is large, and its quality is large, so it cannot be used for on-site needs at will; for any automobile wire, it can only be selected and used according to the established fault setting function of the equipment, and it is dedicated to special vehicles, with poor versatility
