Industrial Equipment Harness Processing Frequently Asked Questions

1. Industrial equipment harness processing connector failure
Various types of equipment connector terminal joints irregularities caused by accidents are common, the reason is that many installers in the installation of wire harnesses, do not pay attention to the quality of the installation, in should be used in insulating sleeves do not install sleeves, should be used in the place of the junction box did not install the junction box, resulting in the interface when the power is on the interface heat fever, and then make around the gradual drying, carbonized, and then produce incineration.
There are many connection points on the harness, such as wires and switches, wires and electrical appliances, wires and junction stakes, wires and shelter device connection points and other parts of these joints and wires are not different from other parts of the joints when the joints of the insulation layer is stripped off, if the wrapping cloth wrapped around a bad so that the two wires produce a collision, it is very likely to cause a short-circuit, fever, or electric sparks.
2. Industrial equipment wiring harness processing touch line failure
Wires are generally insulated shelter, as long as the insulation is not destroyed, although the two wires touch, there will be no difficulty.
3. Industrial equipment harness processing connector loosening
Some of the joints in the installation of quality is relatively good, but due to thermal expansion and contraction reasons, or long-term vibration, will make the joints loose, such as a bridge bridgehead within the electrical wiring, because the vehicle over the bridge is often violent vibration, so that the joints of the wires are slowly loosened, the contact resistance slowly becomes larger, more and more serious fever!
4. Industrial equipment harness processing conductor linkage oxidation
In the wet and corrosive air environment, the conductor is prone to generate a layer of oxide (in the copper conductor will show copper oxide, in the aluminum conductor is more likely to generate aluminum oxide) this kind of hydride of the motor can be very bad
5. Dust pollution
Soil, dust infiltration into the conductor of the joints, interfere with the contact between the conductor, so that the joints overheating
Industrial equipment harness processing short circuit problem solution.
1. Immediately turn off the power supply, the corresponding batch of equipment to trace the source
2. let engineers and wire processing plant engineers to analyze the defects
3. use some professional equipment to search for equipment
4. Record the relevant data
5. Develop inspection and maintenance programs
   A wire processing plant can beam processing industry stands also need to be able to support the ability. During the operation of electronic wire harness, the heat released will be absorbed by the wire itself, thus causing the temperature of the wire to rise. Wire in the operation process, although constantly in the absorption of current work released heat, but its temperature will not systematically rise. Because the wire in the absorption of heat at the same time, but also in the outside world constantly exothermic, the facts show that the electronic wire harness wire temperature rises gradually after energization, after the temperature is constant at a certain point. In this constant point, the wire absorption, exothermic power consistent, electronic wire harness wire is in thermal equilibrium. But once the temperature exceeds the current limit of operation will appear wire overload.
In our daily life, the use of electronic wire harness is very frequent, we have to use the electronic wire harness according to the different environments, to choose different levels of flame retardant materials. Here to see the electronic harness in the flame retardant grade is how to define? The flame retardant grade of electronic wire harness can be divided into 6 levels, the following we explain in detail from low to high:
1, HB requirements for 3 to 13mm thickness of the sample, the burning speed is less than 40mm per minute; less than 3mm thickness of the sample, the burning speed is less than 70mm per minute; or extinguished before the mark of 100mm.
2, V-2 on the sample after two 10-second combustion test, the flame is extinguished within 60 seconds, there can be burning material falling.
3, V-1 to the sample after two 10 seconds of combustion test, the flame is extinguished within 60 seconds, there can be no incendiary drop down.
4, V-0 on the sample after two 10-second combustion test, the flame is extinguished within 30 seconds, there can be no incendiary drop down.
5、5VB After five 5-second burn tests on the sample, the flame goes out within 60 seconds. Drops of particles must not ignite the cotton. Lumpy samples are allowed to be burned through.
6. 5VA The flame is extinguished within 30 seconds after five 5-second burn tests on the sample. The dripping particles must not ignite the cotton. Lumpy samples are not allowed to be burned through. All the wires of Lianghua Wire meet the qualification of UL US safety certification and EU certification. Strictly in accordance with the standards of its quality system, the product source has traceability.
Different wire harnesses use different interfaces, and electronic wire harnesses process different interfaces. Lianghua wire company for you to organize the classification of electronic wire harness processing interface. Electronic wire harness processing interface classification:?
1, I / O interface chip: most of the chips are integrated circuits, you can enter different parameters and commands through the CPU, and control the relevant I / O circuits, as well as some simple devices to carry out the relevant operations. Common interface chips are: interrupt controller, parallel interface, counter and DMA controller and so on;
2, I / O interface control card: control card is mainly composed of multiple integrated circuits according to a certain logic to form a component, or directly and the same CPU in the same motherboard, can also be a plug-in inserted in the system bus slot above; electronic harness processing interface problems: 1, speed mismatch: I / O devices work much slower than the CPU, and due to the different kinds of different speed differences between also very large; 2, speed mismatch: I / O devices work much slower than the CPU, and because of different kinds of different speeds. Between the speed difference is also very large; 2, timing mismatch: each I / O devices have their own timing control circuit to their own speed to transmit data, can not be harmonized with the CPU's timing?
With the development of Internet technology, the penetration of the Internet into the field of electronics, the acceleration of new product development and business strength and ability to enhance, the Internet electronics industry chain will be in the direction of the depth as well as the development of the electronic field. The market for electronic wire harness has also become a major trend. Then, customers choose electronic wire harness processing manufacturers generally have to consider the following aspects:
First, the strength of the electronic wire harness processing manufacturer verification, 1, the manufacturer's production strength, production strength is mainly judged from the company's size, electronic wire harness processing production equipment and management level. 2, the manufacturer's qualification verification, whether to obtain electronic wire harness processing UL certification, ISO9001, 14001 and other related certification qualifications.
Second, the technical capabilities of electronic wire harness processing manufacturers 1, electronic wire harness processing manufacturers quality assurance.　Electronic wire harness processing process is mainly divided into end pressure (crimping) and molding two ways of processing, electronic wire harness processing manufacturers to design according to the functional characteristics of the harness needs, and after a number of procedures of inspection and full inspection of the product, test the conductivity of the electronic wire harness, resistance, voltage, etc., to ensure that the product yield, to ensure that the customer's quality requirements.2, the production efficiency of the electronic wire harness processing manufacturers. Production efficiency is mainly from the commissioning level of production equipment and technical staff and management staff training and other aspects of the test.
