Terminals requirements

Mechanical structural safety requirements terminals in terms of chemistry and structural materials and moving parts to ensure the safety of live, such as shell edges, hardware aspects of glitches, and various parts of the connection strength, even stable under electrical terminal block exercise conditions sex, above all in the mechanical structure of the power industry requirements for terminals.
2, enclosure protection requirements mainly JB / T 9568-2000 provides for protection class, it is mainly divided into two types, one is solid foreign protection level, one is water damage caused to equipment and products.
3, insulation coordination requirements are mainly based on the materials used, the working voltage and environmental pollution levels, come together to select clearances and creepage distances, thereby protecting the safety of staff and products work, but also make the product does not occur in the over-voltage insulation damage .
4, the tracking index requirement for the product in the course of the surface of the solid insulating materials in the electric field and an electrolyte to form a conductive path, so that the insulating properties of the insulating material housing decline, affecting the safety of the product. If insulation voltage level at the same conditions, tracking index is high, the product creepage distance can be reduced, if the product enters power sector development in this regard, please pay full attention.
5, the thermoplastic material in the work requirements of the deformation, which is mainly of the temperature and the contact resistance of the terminals in the work, the high temperature which causes the deformation of the housing becomes soft, so that the electrical short-circuit, resulting in a serious accident, so the carrier terminals Select the material flow components was very important.
6, electric shock requirements, the structural aspects of the operating element should not be charged, terminal and internal PCB Spring Terminal Block connections should be accessible to this area mainly for screw torque and reliability requirements, should prevent the screw terminals can be touched, Loose wires accidentally shorted. Such as the ground terminal requirements: ground resistance class security products should not exceed 0.5Ω.

5, the thickness of inner core countries have certain requirements, but not very strict.But not a lot of mistakes, only a very small a little bit error generally with the eyes of the.

6, length, no compulsory must play fiber optic cable , but there are many manufacturers alsoplayed meters, not necessarily GB dozen meters, but the General GB generally notdozen meters. Non standard dozen meters that is only a kind of means.

7, the provisions of the state on the wires must play a certain identity, the maximumnot more than 500mm have identified the same next play out, above the generalproduct trademark, factory name, the implementation of standards

mini hdmi cable from the cable industry in the development of competition

The total size of the cable industry and the growth rate has been ranked first in the world. However, the prevalence of quality problems in the industry but for grid security, environmental protection and consumer health and safety of persons buried a significant risk.
"Quality is the life," For many years this slogan slogan by domestic enterprises as truth. However, in the face of fierce market competition, more and more companies have chosen "to life", once the "lifeline" increasingly fragile.
Product concept not only focus on quantity, but WISDOM 15 pin vga cable  also pay attention to product quality. Domestic enterprises tend to have short-term market behavior, ignoring the long-term goal of sustainable development of enterprises. For more serious quality crisis, experts recommend that companies need to change their ideas, mini hdmi cable from a strategic point of view reflect the enterprise value, from the simple "price" competition to "value" competition, and gradually establish the company's core competitive advantage. Cable companies want to build the foundation through the interior of "quality, cost, delivery" aspect of advantages, while opening up new markets with high added value, improve product quality and innovation.
Go connotation type of enterprise development, development of the road refinement mini hdmi cable, key personnel from the interior to enhance the quality and continuous improvement system. To compete with  cable management world-class enterprise, first of all have to grasp ideas and world-class tools and improve the skills and management skills to improve internal staff, build continuous improvement system is the key to business transformation take a good road. As an important economic and social cell, the enterprises themselves should play a "full part" in charge, from raw materials sectors, production and processing, circulation, until the sales cycle, and both are corporate responsibility, should not relax our vigilance on the part of any . This usb extension cable  responsibility is reflected in the corporate control of the quality of their own products, there are no weak links, not buried quality problems, but also the responsibility for the overall image of the product line.

WISDOM mini hdmi cable and introduce the main features

Power cables for transmission and distribution of electrical energy in the power system features a large trunk, the control cables from the distribution point of the power system to power transmission lines connected directly to the power supply of various electrical equipment  WISDOM sfp module appliances. Rated voltage power cables 0.6/1kV and more generally, control cables mainly for 450/750V. The same specifications as power cables and control cables in the production, power cable insulation and sheathing thickness thicker than the control cables.

Analysis hdmi cable HD cable burned when hot-swappable reasons

hdmi cable HD 19-pin female header, put a half pin, unplugging hdmi high-definition cable, when the root HOT PLUG needle first disconnect and then hdmi high-definition cable circuit detects the disconnect notice input output devices, stops working, hdmi cable acts hot-swappable. The reality is that when hot-swappable high-definition cable hdmi port  is often burned, which is static damage by hdmi HD line is very high-speed WISDOM 24 port patch panel digital signal, because of the need speed, sending and receiving chip design, the use of anti-static protection Circuit generally only 5-8KV electrostatic voltage capability, but in real life, if the environment is dry, while there are static voltage conditions, thousands of static voltage V is common in the design of sophisticated source and display side, the general are arranged to sacrifice some margin capacitance ESD protection circuit. hdmi cable, but WISDOM patch panel  some machines in order to save costs without ESD protection circuitry, it may burn when inserted into the chip with static electricity, which is, do HDMI wire testing friends certainly know, there are anti-static requirements, this is the same reason. Another reason related to the grid: Our 2-pin power socket is no ground. General users when installing LCD TVs and projectors, will not another ground wire. This makes it easier to form an electrostatic. For these reasons, in the definition of hdmi cable hot swappable, you  WISDOM optical fiber cable must first blessing, the character of the fight. Online hot-swappable port or device is burned two reasons. Therefore, manufacturers generally do not recommend hot-swappable HD hdmi cable.

China wire mini hdmi cable industry development analysis

Wire and cable occupational dependence on capital is relatively large. Affected by copper, aluminum, plastic and other raw materials quoted, cable production companies facing cost pressures endless. Shortage of funds, capital chain tight become an important factor in small and medium sized cable company to carry out. Followed by shopping increasingly fierce competition, the cable company's mergers and acquisitions, capital combine to become an inevitable trend. Electric floor heating
The device combines
Production equipment is the company's fixed assets, mini hdmi cable company is also an important resource. And each company produced commodities, many transactions are incidental, not often WISDOM hdmi cable for ps3  attack. Thus, the company's production facilities on the president some time aside. Hold the largest resource spoil. So the company must carefully analyze usage of the equipment, the company's production equipment, production lines combined.
China Wire and Cable how to open up the mall puzzle?
Just gather resources, specializing in the primary sector to the cable industry bigger and stronger doing fine. As long as the time to focus on the cable industry, and can help cultivate professional talents and skills accumulation. Many areas are high-tech cable manufacturing industry skill-intensive industries, there is no a strong professional technology team, unable to innovation and research and development skills.
Cables for the Chinese economy into the global mall, mini hdmi cable specification needs more awareness and  WISDOM cat5e ethernet cable national competitions as a sense of responsibility. Reality states that consequently the results would only be done consequently do less well. In future years, making the country the cable industry will continue to experience a difficult period. There must be a number of backbone, has focused on the launch of the cable industry, support from the cable industry in China's national flag. Professional conduct, can along the upstream and downstream industry chain extension goods and conduct space is actually infinite. Carbon fiber heating cables
When China opened up many hours of foreign companies mall, mini hdmi cable we found that in addition to a series of foreign trade barriers maintenance, but also tend to develop norms through skill set of skills barriers. And China is far behind the changing norms new mall. Wind power, nuclear WISDOM cat6 network cable  power, photovoltaic composite grid smart grid and other cutting-edge products are not involved in the early national standard.
I fear, followed by cable gradually seasoned professional, career competition increased, the company annexation, reorganization, bound to promote the product, personnel, funds, equipment serving the industry, among the combined company from scratch.

The main explanation hdmi cable

HDMI and DVI digital signal processing effects are exactly the same, they are all derived from the same standards out of the interface. Difference is that HDMI is connected with audio, and DVI generally do not, under special circumstances can be achieved, but the effect is not good.
So, hdmi cable if your monitor with speakers, be sure to HDMI, otherwise no sound. If not, then see if you have a graphics  WISDOM mini usb connector card and monitor are what interface to connect directly without conversion as well. If you have HDMI, has DVI, but no speakers under the display cases, individuals tend to DVI, since HDMI is designed to push the kind of the kind at any time, the connection is not solid, in terms of desktops someday thread out also very depressed. In addition, HDMI audio signals that the road will be useless interference somewhat, but it is slightly worse than the actual DVI is almost impossible to distinguish. Each PCB board will be applied to electronic products, PCB board in addition to capacitors, resistors, IC, diodes, transistors, etc. hdmi cable as well as the most important thing you  WISDOM hdmi to dvi adapter can cable needle holder, needle holder by welding, then it leads to a connector line, called the cable, the benefits of cable that requires no soldering, terminal machine that is cold to be completed. Cable with connectors, easy maintenance, and debugging. Among the equipment, if the line is short-circuited, we just need to change a line of the same size line without the need to use a soldering iron, so environmentally friendly and simple. Bailev designed to do a variety of cable, can provide you with various  WISDOM 24 port patch panel options. PCB board cable, also known as terminal cable is determined by the needle holder, plastic shell, terminal, wire, cable processing, generally widely used inside the device. Is also a priority can not be ignored.

Chlorinated polyethylene mini hdmi cable cable technology features

(A) mixing a chlorinated polyethylene main chain contain a double bond, the main chain is not easy to cut the plastic mechanical virtually no effect on Mooney viscosity, so no mastication. 2, CPE plastic suitable for both open mill mixing, kneading and suitable mixer. Before using the open mill mixing, because CPE is powdery, need to first CPE at 70 ℃ to 90 ℃ on the WISDOM fiber optic connectors  mill through thin plastic Tempered translucent, then kneaded. CPE rubber kneading with mixer, mix the temperature should be controlled in the range of 130 ℃ ~ 150 ℃ appropriate. If the peroxide was added directly to the mixer and kneaded in the mixer to control the temperature peroxide "from" sulfur temperature. In addition, CPE rubber mixing with the mixer, the glue should be enough installed capacity, mini hdmi cable should WISDOM cat5e keystone jack  generally be above 95%. (B) extruding CPE good scorch resistance, smooth surface can be extruded cable products. Extruder screw length of less than 12, the extrusion quite difficult. Hot feed extruder, to improve the surface quality of the cable. When the aspect ratio is greater than 12, the cold extrusion, hot extrusion agent can smooth surface cable. Since CPE CR mobility better than good, plastic is not easy, so when extrusion, body  scart cable temperature was controlled at 75 ℃ ~ 85 ℃ in terms of extrusion temperature; mini hdmi cable head temperature controlled at 85 ℃ ~ 95 ℃ appropriate. (C) curing CPE applies to pipes continuous vulcanization. To ensure the productivity, it is necessary to raise the temperature of curing, generally at a steam pressure of 1.2 ~ 2.0MPa continuous vulcanization. The temperature is too low, the amount of the curing system or water cooling or water cooling section short segments, easy to produce bubbles. In addition, CPE are heat-sensitive materials, extrusion and vulcanization stage should be to control the temperature, high temperature, easy to produce pores.

With a network cable can do to make mini hdmi cable

I want to do with a network cable USB extension cable. Access wireless card. Received outside the window. Because the suburbs each had a bad signal to get a good spot where the signal near the window. So WISDOM barrier terminal block  I want to use a USB extension cable to drag cards received from outside the house. Fear of weak signals. Useful insufficient power supply lines do see. But how to identify a network cable with good or bad? Is to look at the copper content? But do not see the time to buy. Or watch cable manufacturers. Or softness? The two were connected to the power remaining two groups WISDOM ethernet jack  received a set of three remaining two signal lines. Feasible? About 5 meters long. Plug ruined a USB extension cable. Window with a powered mini hdmi cable box will good points? But trouble will also house the cable to be unplugged. I hope you give points. You mean the family does not need to rub someone else's broadband router network? If the home is installed on the line home broadband equipment that will inevitably router, whether you're wired or wireless Internet access are unlikely to signal bad, after all, will be taken into account when installing these issues. You want to close the window wireless card is WISDOM dvi to hdmi adapter  what the reason for this? Then talking back to a dedicated mini hdmi cable extension cord meters have very cheap prices, so why use a network cable at great pains to change it? Classification is a few lines like, now is a better category 6 twisted pair cable 8-core, USB extension cable can not do it I do not know it. Instead of buying this might as well change the network cable directly to buy USB extension cable.

Grasp the common coaxial mini hdmi cable, cable types and characteristics

1 Consider transmission attenuation : the case where a high floor, and distant from the monitoring center should carefully consider the transmission attenuation problem. When selecting cables, we all know  WISDOM cat6 keystone jack better than Thick thin cable , but should also be aware SYWV physical foaming cable SYV than solid cable , high- series cable is superior to low- programmed cable , copper cable is superior to " Copper Clad " cable, copper is better than aluminum-magnesium alloy netting netting . -
. 2 mini hdmi cable high frequency attenuation concern : the low-frequency component of the brightness / contrast attenuation easy to find and solve the most important cable transmission characteristics that the higher the frequency the greater the attenuation , high frequency attenuation mainly affect the clarity and resolution, paying particular attention to summary of the observation method of image quality . Cable characteristics and laws in this regard are : Thick better than thin cable , foam is better WISDOM barrier terminal block  than solid , but the same type of "high- and low- compiled code , like high frequency attenuation .
3 Consider mini hdmi cable life: the flexible cable is better than regular cable , thin cable is better than thick cable ; still one of the most easily overlooked problem : Cable adhesion between the layers , that is, when the cable between the layers lengthwise force in the opposite direction , relative sliding occurs whether the high-level elevator cable length up to 100 m perpendicular to the wiring , the cable outer sheath is fixed to the trailing cable , which is a "soft fixed," allowed cable deformation constant ( destroy coaxial ) , so that , in the reciprocating movement of the elevator within WISDOM fiber optic cable  the cable layer , under gravity , will gradually " dip" , and slowly pulled off or wire braid , the performance of the signal gradually weakened, increasing interference ; there is no such standard cable technology , a simple way to check is to take a meter cable , peel the layers at one end , one hand holding the ends of the cables , another person with pliers to pull the inner cable : in order to pull wire, insulating layer , woven mesh , the size of adhesion experience to make a reasonable estimate , poor adhesion , easy sliding try not to choose. The performance of many of the cable is not good , should be carefully chosen .
