Использовать соединение для моделирования робота ниже является электропроводку кожи, как присутствие человека кровеносных сосудов. Но между провода упряжи и кабель будет неизбежно падать, и четыре оправка обжимной Алюминиевык способность, тяговое усилие лучший шаблон давления.

Робот шели в жизни каждого, но я до сих пор не верят, что роботы могут заменить людей. В конце концов это то, что мы делаем это.

Charging piles in electric vehicles

New energy vehicle is a kind of car which uses unconventional vehicle fuel as a power source and integrates advanced technology of vehicle power control and driving force. It is a kind of car with new technology and new structure. Nowadays, the problem of energy shortage and environmental pollution is getting more and more serious. New energy vehicles have become the trend of the automotive industry. Of course, this trend has also led to the popularity of charging piles in public places.

The function of the charging pile is similar to the tanker inside the gas station. It can be fixed on the ground or the wall. It can be installed in the public buildings (public buildings, shopping malls, public parking lots, etc.) and parking lots in residential area or charging stations. And the charging pile can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with the AC grid, and the charging plug is arranged at the output end for charging the electric vehicle. Charging piles generally provide two kinds of charging methods: normal charging and fast charging. People can use the special charging card to charge in the human-computer interaction interface provided by the charging pile, and carry out the corresponding operation, such as charging way, charging time and cost data printing. Charge pile screen can display charge capacity, cost, charge time and other data.

The charging pile’s special structure determines the characteristics of the automatic communication system is wide coverage and short communication distance. And with the development of the city, the network topology requires a flexible and scalable structure. Therefore, the selection of charging pile communication mode should consider the following aspects:

1.     The reliability of communications - Communications systems must maintain communication with long-term strong electromagnetic interference or noise interference in harsh environments.

2.     Construction costs - In the premise of meeting the reliability, taking into account the cost of construction and long-term use and maintenance costs.

3.     Two-way communication - Not only to achieve the amount of information uploaded, but also to achieve the control of the release.

4.     Multi-service data transfer rate - With the future growth of terminal traffic, the communication between the main station to the sub-station and the sub-station to the terminal makes the requirements of achieving multi-service data transfer rate higher.

5.     The flexibility and scalability of communication - With the development trend of "ALL IP" network technology and the continuous growth of power operation business, it is necessary to consider IP-based service bearer, and to facilitate installation, commissioning, operation and maintenance.

Charging pile’s high communication requirements also determines its high requirements in construction and production. There are strict standards on the production technology, manufacturing processes and production control management when producing charging pile. In the process of producing charging pile, each process should be strictly in accordance with all kinds of standards. It is a process that combines a large number of electronic components, mechanical mountings, wires, terminals, and connectors together step by step by adopting different connection ways and installation methods.What’s more, processes like wiring harness processing, grounding molding, wire and terminal crimping process are very critical. if the quality can’t be achieved, it will make the charging pile has serious security risks.

Precisetool specializes in manufacturing M22520 series crimping tool and those crimping tools can complete the crimping of wires and terminals in charging piles more perfectly and efficiently which has a very important significance in improving the overall quality of the charging pile wiring harness and plays a positive role in promoting the development of the electric car industry. Also, it will make contributions to the popularity of new energy vehicles in China. M22520 series crimping tools are also widely used in crimping wire and terminals in aviation connectors, military connectors, circular connectors, rectangular heavy duty connector, RF coaxial connectors, printed circuit board connectors, automotive connectors, optical connectors, etc. In addition, in order to further expand the scope of application of crimping tools, Precisetool specifically designed and produced a series of customized crimping tool including manual crimping pliers, pneumatic crimping pliers, pneumatic desktop crimping machine, by changing the wire crimp range, expanding the diameter of the through-hole and other methods according to customer’s special demands, which in the meanwhile, greatly enriched the product catalog.

It is conducive to the digestion and absorption of imported technologies, system integration and imitation innovation. It is conducive to promoting the diffusion of foreign advanced technology in domestic enterprises and rapidly increasing the technological capability of Chinese enterprises.

The electronic technology plays a vital role in aerospace aircraft, so it is very necessary to develop aerospace electronic technology. The electronic equipment on aerospace aircraft is characterized by: ①small size, light-weighted and less power consumption; ② can work in harsh environment; ③ high efficiency, high reliability and long life. The overall development level of China's manufacturing industry is improving, which is conducive to promoting the development of aerospace technology. Every success in aerospace program has benefited from every detail of the manufacturing process. This means that each process of manufacturing aerospace aircraft must be strictly in accordance with the corresponding standards. Any tiny error may lead to the failure of the entire aerospace program, or even resulting in irreparable economic losses and even flight crew casualties. Even the choice of materials or the use of crimping tools may have a decisive impact on space flight experiments. Communication and control is a must to ensure high reliability of spacecraft. In the extremely harsh environment such as aerospace, various types of aviation connectors are widely used to achieve the communication connection technology. Currently, M22520 (AS22520) four-indent crimping is a way of high reliability of the terminal and wire connection.
