Description

Device for detecting on-off and sequence of wire harnesses
Technical Field
The utility model relates to a pencil detects technical field, particularly, relates to a detect device of pencil break-make and line preface.
Background
With the continuous improvement of the requirements of people on the safety, comfort, economy and emission of automobiles, the application of automobile electrical systems is more and more extensive, and wire harnesses are more and more complex. The wire harness is called as an automobile 'blood vessel' and is considered as a central nervous system of a vehicle, and the connection between the components of the existing electric appliances is widely performed by the wire harness. The wiring harness refers to a component for connecting a circuit, which is formed by pressing a contact terminal punched by a copper material and an electric wire and cable, then externally molding and pressing an insulator or adding a metal shell, and the like, and bundling the wiring harness, wherein the wiring harness is usually formed by a multi-core wire and is branched to run according to functions and requirements. Nowadays, automobile functions become intelligent day by day, vehicle electronic systems become more and more complex, and electronic control system wire harness that follows with is more and more complicated, and the cable core number is more and more also more and more. For a vehicle wire harness, since a control object is complicated, a trunk wire harness is generally as many as several hundred cores. The wire harness is electrically connected with components such as an electronic control unit, a sensor, an actuator and the like through cables and connectors, so that a complex system is formed.
After the wire harness is shipped from a factory, various performance tests such as short-circuit, open-circuit, and continuity are generally performed. On engine rack and car, the pencil has all been tied up fixedly, in case break down, needs the on-the-spot solution, and ordinary universal meter can only detect the break-make of a cable once, and detection efficiency is low. And the two ends of the tested cable are searched according to the definition of the connector pins on the wire harness, and because the pin hole diameter of the female connector is small, and the meter pen of the multimeter is thick, the meter pen of the multimeter cannot be directly inserted into the pins of the female connector, errors are easy to make in detection, and the detection speed is low, obviously, the detection method excessively depends on the personal working capacity and proficiency of engineers.
The jig is a large tool for carpenters, ironmen, pincers workers, machines, electric controls and other handicraft articles, and is mainly used as a tool for assisting in controlling positions or actions (or both); the jig can be divided into a process assembly type jig, a project test type jig and a circuit board test type jig. An electrical measuring instrument is a measuring instrument that compares a measured electrical quantity or parameter to an electrical standard or provides an accurate ratio. A large number of relatively measuring instruments (short for comparative measuring instruments) used in scientific research, quantity transmission and industrial testing belong to the electric measuring instruments. The method has wide application and plays an important role in the field of measurement and test. The electric quantity tester mainly utilizes a proportional technology to realize measurement; for direct current, the voltage proportion formed by the voltage generated on the two resistors by the same current or the current proportion of the two resistors under the same voltage is utilized, and then the unknown quantity is measured by combining a standard device; the device for providing the proportion is like a balance, and the standard device is equivalent to a weight; the measuring instrument made according to the ratio is provided with a direct current bridge, a direct current potential difference meter and the like; the electric measuring instrument mainly utilizes a proportional technology to realize measurement; for direct current, the voltage proportion formed by the voltage generated on the two resistors by the same current or the current proportion of the two resistors under the same voltage is utilized, and then the unknown quantity is measured by combining a standard device; the device for providing the proportion is like a balance, and the standard device is equivalent to a weight; the measuring instrument made according to the ratio is provided with a direct current bridge, a direct current potential difference meter and the like; for alternating current, the measurement principle is basically the same as that of direct current, except that the resistor is replaced by impedance; thus, in general, the ratio is complex; real or imaginary ratios are only a special case; in addition, two magnetically coupled coils can be used to obtain a real ratio of voltage proportional to the number of turns or a real ratio of current inversely proportional to the number of turns. The measuring instruments made according to these principles include classical ac bridge, inductive coupling proportional arm bridge, ac potential difference meter, inductive voltage divider, current comparator, mutual inductor, etc. In addition to the above-mentioned electrical measuring instruments, there are equivalent circuit elements composed of electronic circuits, and active bridges and digital bridges made by digital techniques; since the 70 s in the 20 th century, the combination of the measuring instrument and the microcomputer expands the functions and develops towards intellectualization.
At present, the on-off and the line sequence of a wire harness are detected by generally adopting a mode of detecting the on-off by using a universal meter, the detection efficiency by using the universal meter is low, and the defects of the on-off and the correct line sequence of the wire harness cannot be detected; when defects such as short circuit, needle drop appear in the pencil, can cause the connector function to lose, its quality directly influences the transmission effect of electric power or signal, and in case the quality problem appears, often can produce serious consequence, and the later stage reprocesses the cost and increases by a wide margin.
