Optional elements of cable

Wire and plug in terminal block as the main carrier of power transmission, are widely used in electrical equipment, lighting, household appliances and other lines, its quality directly affects the quality of the project and the life and property safety of consumers. There are a lot of wire varieties on the market, want to use the appropriate wire according to the power load your.
On the market sell wire some cheap and some more expensive, some people often but to relatively cheap, cheap, wires, often have many did not reach the performance that he shows, there may bring many security hidden trouble to yourself. Production technology content of wire is not too high, the raw material is not much difference, if cheap too much, or cut corners, or the number of not giving enough. How to identify it. I give you several methods for easier identification:
1, to look at the packaging, GB wires tend to do relatively well, neat, hand up have a sense of quality.
2, to open the package to see the inside of the wire, the wire GB 1.5 - -6 square wire requirement is thick skinned (insulation thickness) is 0.7mm, too thick is non-standard, corresponding to his inner core is sure enough, line skin you can force pull, not easy to tear is general is the national standard of
3, with the fire, extinguished within 5S after leaving, have certain flame retardant function for GB line.
4, look at the inner core, the inner core material (copper) brightness higher copper is better, and photometric mini hdmi cable uniform, shiny, no sense of hierarchy. The national standard requirements within the core must use oxygen free copper. Non standard such as black rod copper, there may be hidden dangers of accidents.
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 meters, but there are many manufacturers also played meters, not necessarily GB dozen meters, but the General GB generally not dozen 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 maximum not more than 500mm have identified the same next play out, above the general product trademark, factory name, the implementation of standards

Hdmi extension cable features an infrared receiver

hdmi extension cable infrared receiver features: 

1 External colloids using electrical terminal block, and add coloring, play better shielding effect. 

2 senior internal IC chip imported from Germany and PD, achieve longer distances and more sensitive receiver acceptance angle, to ensure the 21 pin flat scart cable and consistency of performance. 

3 fixation using high-temperature aging process, to ensure infrared receiver bracket rust during storage.

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.

How to use micro hdmi cable

High-Definition Multimedia Interface ( English : High Definition Multimedia Interface, HDMI) is a digital audio / video interface technology is suitable for special type of digital video transmission interfaces , which  can simultaneously transmit audio and video signals , the maximum WISDOM rca audio cable  data transfer rate of 5Gbps . micro hdmi cable at the same time without having to send the signal before the D / A or A / D conversion. HDMI can be used with broadband digital content protection (HDCP) high- definition multimedia interface ( English : High Definition Multimedia Interface, HDMI) is a digital audio / video interface technology, the interface is a special type of digital video transmission suitable for how to connect a TV with an HDMI cable
