The common problems in industrial equipment wiring harness processing, different industrial equipment wiring harness in the machining process will have different problems and seriously affects the quality of the production equipment, the cost of loss, to reduce industrial equipment wiring harness problem, avoid unnecessary losses, to know about the problems in the industrial equipment wiring harness processing, analysis and make a solution.
1. Wiring harness processing joint failure of industrial equipment
Accident caused by all kinds of non-standard equipment connector terminal connector, the reason is that many of the installation personnel when installing a wiring harness, don't be careful with the quality of the installation, should be not installed casing with insulation casing, should use the junction box where no junction box, leads to power outlet fever fever, and then make the area gradually dry, carbonization, and then burned.
Wire harness, there are many join points, such as electric wires and switches, wires and electrical appliance wiring pile head, wire protection device connection points such as the joint part is different from other parts of the wires are different, when the insulation joint strip off, if wrapped around and not let the two lines of touching, it is likely to cause a short-circuit, fever or cause electrical discharge
Wires are generally insulated, as long as the insulation is not destroyed, although the two lines collide, it will not produce difficult
3. The wiring harness processing joint of industrial equipment is loose
Some joint during installation quality is good, but due to the reason of heat bilges cold shrink, or a shock for a long time, can make the loose connection such as bridge bridgehead in electrical wiring, because when vehicles cross the bridge often produce violent vibration, to loosen wire junction slowly, slowly contact resistance, fever is more and more serious
4. Oxidation of conductor connection during wiring harness processing of industrial equipment
In wet and corrosive air, the conductor tends to form an oxide layer (copper oxide on copper wire, alumina more readily on aluminum wire) and the motor performance of such hydrides is poor
5. Dust pollution
Soil and dust infiltrate the connecting points of conductors, interfering with the contact between conductors and overheating the connecting points
Solution to short circuit problem in wiring harness machining of industrial equipment
1. Turn off the power immediately and trace the source of the equipment of the corresponding batch
2. Have engineer and engineer of wire processing plant conduct defect analysis
3. Use some professional equipment to search
4. Record relevant data
5. Develop inspection and maintenance plans
A wire harness processing plant can bundle processing industry standing is also required to be able to support. During the operation of the electronic wire harness, the heat emitted will be absorbed by the wire itself, thus causing the temperature rise of the wire. The temperature of the wire does not rise even though it is absorbing the heat released by the current. Because the wire is absorbing heat at the same time, it is also constantly releasing heat to the outside world. The fact shows that the temperature of the electronic wire harness wire rises gradually after it is energized, and the temperature is constant at a certain point. At this constant point, the absorbing and exothermic powers of the wire are consistent, and the wire of the electronic harness is in a state of thermal equilibrium. Overloading occurs when the current limit for temperature operation is exceeded.
In our daily life, the use of electronic wiring harness is very frequent, we need to choose different grades of flame retardant materials according to the different environment of electronic wiring harness. Now let's see how flame retardancy rating is defined in electronic wiring harness. The flame retardant grade of electronic wiring harness can be divided into 6 levels, which are explained in detail from lowest to highest:
1. HB requires that the combustion rate be less than 40mm per minute for samples with thickness of 3 to 13mm; For samples less than 3mm thick, the combustion rate is less than 70mm per minute; Or extinguish it in front of the 100mm mark.
2, V-2 on the sample after two 10-second combustion test, the flame in 60 seconds out, can have combustion dropped.
3, V-1 on the sample for two 10 seconds after the combustion test, the flame in 60 seconds, no combustion dropped.
4, V-0 on the sample twice 10 seconds after the combustion test, the flame extinguished in 30 seconds, no combustion dropped.
5, 5VB on the sample five times 5 seconds after the combustion test, the flame extinguished in 60 seconds. Falling particles cannot ignite cotton. Block samples are allowed to burn through.
6, 5VA on the sample five times 5 seconds after the combustion test, the flame extinguished within 30 seconds. Falling particles cannot ignite cotton. Block samples are not allowed to burn through. All the wires of lianghua wire are in line with UL USA safety certification and EU certification. Strictly in accordance with its quality system standards, the source of products can be traced.
Different wire harnesses use different interfaces, and the machining interfaces of electronic wire harnesses are also different. Lianghua wire co., Ltd. will sort out the electronic wiring harness processing interface for you. Electronic wiring harness processing interface classification:?
1. I/O interface chip: most of the chips are integrated circuits, which can input different parameters and commands through the CPU, and control related I/O circuits and some simple equipment for related 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 a number of integrated circuits according to a certain logic of a component, or directly and CPU in the same motherboard above, can also be a plug-in in the system bus slot above; Problems existing in electronic wiring harness processing interface: 1, speed mismatch: THE working speed of I/O equipment is much slower than CPU, and due to the different types, the speed difference is also very large; 2. Timing mismatch: Each I/O device has its own timing control circuit and transmits data at its own speed, which cannot be unified with CPU timing.
With the development of Internet technology, the penetration of the Internet into the electronic field, the acceleration of new product development and the continuous enhancement of enterprise business strength and ability, the Internet electronic industry chain will be deepened and the development of the electronic field. The market for electronic wiring harnesses has also become a major trend. So, customers choose electronic wiring harness processing manufacturers generally consider the following aspects:
1. The production strength of the manufacturers is mainly judged from the scale of the company and the production equipment and management level of electronic wiring harness processing. 2, the manufacturer's qualification verification, whether to obtain electronic wiring harness processing UL certification, ISO9001, 14001 and other relevant certification qualifications.
1. Quality assurance of electronic wiring harness processing manufacturers. Electronic wiring harness processing process consists of side pressure (pressure) and forming two ways to carry on the processing, electronic wiring harness processing factory according to the wiring harness features design demand, and through multiple working procedure of inspection and full inspection product, the wire and test electrical connectivity, resistance, voltage, etc., to ensure that the product yield, guarantee the quality of the customer requirements. 2, the production efficiency of electronic wiring harness processing manufacturers. Production efficiency is mainly tested from the debugging level of production equipment and technical personnel as well as the training of management personnel to employees.
