Technological characteristics of cable

(1) process flow and equipment layout of production
Production workshop of equipment must be according to the requirement of products and reasonable process emissions, the half finished product of each stage, orderly transfer. Device configuration to consider differences in the production capacity of the production efficiency of the balance, some devices may be configured to two or more, to make the production line's production capacity to balance. Thus the reasonable selection of equipment combination and production site layout, must to balance considering according to products and production capacity.
(2) the organization of production management
Production organization and management must be reasonable and scientific, strict and meticulous, careful and accurate, the operator must be strict in one's demands, according to the requirement of process execution, any link problems, will affect the process smooth, affecting the quality of products and delivery. Especially in multi core hdmi dvi cable , a line on the basic unit of length or shorter, or quality problems, then the whole cable will be insufficient length, scrap. Conversely, if a unit length is too long, it must be off the waste.
(3) quality management
The mode of production of large length of continuous superposition and combination, so that the production process of any link, instantaneous point problem, affect the whole cable quality will. Quality defects occurred in the inner layer, but not found in time to stop production, so the loss caused by the. Because the wire and RCA audio cable production is different from the assembled products, can be disassembled and replaced the other; any part or process quality problems of wires and cables, is almost unable to restore and remedy for this cable. After the treatment is very negative, not cut short is degraded, or scrap the whole cable. It can not be opened again.
Wire and cable quality management, must run through the entire production process. Quality management and inspection department to the whole production process of tour inspection, operation self checking, process under the mutual inspection, this is to ensure the product quality, an important guarantee to improve the economic efficiency of enterprises and measures.

The introduction of fixed head

Cable sealing sleeve is a suitable connection cable power supply, also can protect the cable, so it won't escape. Cable sealing device is placed in different categories,depending on whether the glands for general processing industry or in need of protection, prevent the risk is too high or the explosion temperature. Into the armored cate5e network cable glands or no armoring layer and a different type of gland will be required for each variety. The gland itself, can be made of metal, such as copper or aluminum, or plastic, the material is useful in different environments.
When the electrical work is completed, it may be no cable sealing, to ensure theelectrical equipment wire, but there are several reasons, this is a bad idea. Glandsprovide sealing power, so as to ensure that the RCA audio cable will not slip during operation.Security is also provided, because the mini displayport cable gland to ensure that electricity can not attached to anyone nearby, causing bodily harm. Glands usually provide other safety features, such as the earth wire or insulated cable.
To have two categories: Industrial and hazardous for RCA video cable sealing. Industrial cablesealing joint is a general use of the gland, in order to meet the requirements ofgeneral risk, so it is useful or dangerous explosion in high-temperature environments.If the environment is harmful substances, the use of dangerous gland, because these glands to meet additional requirements necessary. They are fortified with extra, so that they can resist common glands cannot withstand the temperature and external forces.
Two types of cables can be sealed sleeve is classified as armored or unarmoredcable into, which will play glands work will rebound. Armored cat6 ethernet cable will need a gland,can clip into the wire, and the ability to terminate the energy from the armor part. Nonarmoured line does not require termination, but the glands need highly protected andpreserved, in order to maintain the safety of wire.
Most cable gland cell is made from brass, which is considered, as a general materialis resistant to corrosion and electrical conductivity. In the aluminum and the presence of moisture at the same time, the corrosion of brass can start. Brass is often associated with other metal plating, to make the gland is stronger, better corrosion.Plastic is often used as an alternative to metal glands.

Function of mini hdmi cable

Mini hdmi cable not only meet the highest quality 1080P resolution, but also support DVD Audio, the most advanced digital audio formats, support for eight-channel stereo 96kHz or 192kHz digital audio transmission, but with only one HDMI cable, eliminating the digital audio cable. Meanwhile HDMI standard has extra space can be used in future upgrades of audio and video formats. Sufficient to meet a 1080p video and an 8-channel audio signals. And because a 1080p video and 8-channel audio signal is less than the demand for a 4Gbps, HDMI therefore there is a great margin. This allows it to be connected with a DVD player, cable receiver and PRR. Alsomicro usb cable supports EDID, DDC2B, and therefore has a HDMI device has a "plug and play" feature, automatically "consultation" between the source and display devices, automatically selects the most appropriate video / audio formats.
  HDMI and DVI interfaces, compared with DVI Mini HDMI cable  nterface, smaller volume, and can simultaneously transmit audio and video signals. dvi cable ength can not exceed 8 meters, otherwise it will affect the picture quality, but HDMI can transmit as far as 15 meters. As long as a mini hdmi cable can replace up to 13 analog transmission line, a home entertainment system can effectively solve the tangled mess behind the connection problem.
