Mid-Autumn Festival holiday notice

The Mid-Autumn Festival is a traditional cultural festival popular in China’s many ethnic groups and Chinese cultural circles. It has become one of the traditional Chinese festivals with the Spring Festival. Influenced by Chinese culture, the Mid-Autumn Festival is also a traditional festival for some Chinese in East Asia and Southeast Asia, especially local Chinese. Since 2008, the Mid-Autumn Festival has been listed as a national legal holiday. On May 20, 2006, the State Council was included in the first batch of national intangible cultural heritage.

Since the ancient times, the Mid-Autumn Festival has been worshipping the moon, enjoying the moon, worshiping the moon, eating moon cakes, enjoying sweet-scented osmanthus, drinking sweet-scented osmanthus wine, etc., which have been passed down to the present and have been enduring for a long time. The Mid-Autumn Festival celebrates the hometown of the people with the symbol of the moon, and misses the feelings of their loved ones, praying for a good harvest and happiness, and becoming a colorful and precious cultural heritage. The Mid-Autumn Festival and the Dragon Boat Festival, the Spring Festival, and the Ching Ming Festival are also known as the four traditional festivals in China.

Group building-Yichang two-day tour

2019 We meet Yichang Three Gorges, Passion Waterfall, Qingjiang Gallery, cool summer. To enrich the cultural life of our employees and improve the company’s welfare, we would like to thank all the staff for their hard work and hard work. The company specially organized this event and hoped to promote mutual understanding and mutual solidarity among employees through this event.

The event lasted for two days, and there were two main activities, namely, the Three Gorges Waterfall and the Qingjiang Gallery. After all the company members got off the bus, we went through a five-hour drive and finally arrived at the beautiful scenery and suitable temperature in Yichang. The first trip to the Three Gorges Waterfall area.

The Three Gorges Waterfall is a national AAAA-level tourist scenic spot. It is known as “China’s Top Ten Famous Waterfalls”. The Three Gorges Waterfall has a total length of 5 kilometers. It is against the water, and some of them are soothing and soothing. They suddenly fall, and there are sounds. Pour down along the rock wall; some are interlocking, waterfalls and waterfalls are connected, forming a rare cascade waterfall, beautiful, enjoying the deep canyon, Qingshan Pinnacle, clear water, flying waterfall, the Three Gorges Waterfall 102 The meter is nearly 80 meters wide and flows straight down. It is like a rainbow and is spectacular. Along the way, you can see dozens of natural landscapes such as the paper paste hole, the Tibetan Buddhist cave, the long bridge Feidu, the four, the wild man valley, the macaque paradise, the fairy waterfall, the pearl waterfall, and the Xiaofeng Buddha. Experience the unique zero-distance “wearing” waterfall in the waterfall, let people fully feel the joy and passion of the “collective wet body”, let us relax and enjoy the game. After the tour, drive to the hotel.

On the second day, we drove to the Qingjiang Gallery Scenic Area of the national AAAAA-level tourist scenic spot, arrived at the parking lot parking lot of the Qingjiang Gallery in Geheyan, watched the dam of the Heyman Hydropower Station, and traveled to the Tujia Wind and Rain Corridor to feel the Tujia blowing the welcome music. Cross the Ba people time and space tunnel and visit the Tujia style street. Qingjiang Gallery travels on a boat and takes a boat trip to the Tujia family’s birthplace – Wuluo Zhongli Mountain, along the way to see the beautiful scenery of the Qingjiang River: Qingjiang Small Three Gorges, 30 degrees north latitude island, Jiangjun Island, Pingluo Lake, Fairy Peak, and Mount Foshan Waiting for the landscape, after arriving at Wuluozhong Mountain, after the Chinese meal, visit Wuluozhong from the mountainous area: Xiangwang Temple, Shishentai, Salt Goddess Stone Statue, Xiangwang Temple, Baihutang, and worshipping Tujia ancestors.

Through this event, the communication between our employees has deepened, the friendship and cohesion between the groups have been strengthened, and more importantly, we have relaxed our mind and body, and then we will work in a better state to meet the bigger The challenge.

RJ45 Female Connectors  8P8C 180 Degree with LED and Shield

Things we need to know in RJ45 connectors pin manufacturing

The contacts of RJ45 connectors are the core components to ensure the resistance and reliability in using. And the contact resistance is mainly affected by the contact material, the impact of vertical pressure, surface morphology, application voltage and current, and other factors.

RJ45 Female Connectors  8P8C 180 Degree with LED and Shield

1) contact material

The electrical connector of different material and technical conditions for the production of the same specifications mating contacts, contact resistance provides a different assessment indicator. Rapid separation of electrical connectors totals resistance to environmental norms GJB101-86 predetermined diameter of 1mm contact mating contact resistance of copper alloy ≤5mΩ, ferroalloy ≤15mΩ.

2) The surface pressure perpendicular to the contact surface

Perpendicular to the surface of the pressure contact means in contact with each other and perpendicular to the surface of the contact surface of the force. With vertical pressure increases, the number of contact points and the micro area is also increasing, while the contact point of transition from micro elastic deformation to plastic deformation. Resistance decreases due to the concentration, leaving the contact resistance is reduced.

The contact pressure is primarily dependent on the geometry and material properties of the contact member.

3) surface morphology

Including the design of the shape of the surface morphology and the state of the environment, the more loose surface membrane contacting surface may be due to dust, rosin, oil and other mechanical attachment in the contact surface formed by deposition, this layer of film because the table easily fitted with a particulate matter hidden in microscopic pits at the contact surface, the contact area is reduced, the contact resistance increases, and highly volatile. Second, the membrane fouling due to physical adsorption and chemical adsorption formed on the metal surface is mainly chemisorption, which is accompanied by physical adsorption after electron mobility generated. Therefore, some of the high-reliability requirements of the product, such as aerospace electrical connector assembly must be clean environmental conditions and improve the cleaning process necessary structural sealing measures, the use of units must have good storage and use of operating environmental conditions.

4) Voltage

When using the voltage reaches a certain threshold, the film will contact the breakdown, leaving the contact resistance decreased rapidly. However, due to the thermal effect accelerates the chemical reaction layer near the area of the film has some repair. So resistance is nonlinear. In the vicinity of the threshold voltage, the voltage drop will be small fluctuations in the current may cause twenty times or several times range. The contact resistance change dramatically, not to understand this error occurs when testing and useful contacts.

What’s the structure of RJ45 connector?

What is RJ45 connectors?

RJ is the abbreviation of Registered Jack, which means registered socket. And it is the interface that describes the public telecommunication network in the standards of FCC (US Federal Communications Commission).

RJ series connectors are widely used in civil, industrial, medical, communications and other fields. They have a bright future in civilian areas, such as telephone, network adapter, PC, Notebook, Router/Switch, security cameras, game consoles and other devices. Commonly, RJ connector series can be divided into RJ11, RJ14, RJ25 and RJ45 Ethernet interface (network interface).

The following numbers of RJ connector represent the number of wires. So the RJ45 connector is a standard 8-bit modular interface of a computer network. There are many ways of common saying, for example, RJ45 socket, RJ45 connector, RJ45 network port, RJ45 female socket, and so on.  Renhotec mainly offer RJ45 connector for PCB/Panel mount, and RJ45 cable.

3 Structure of RJ45 connectors

The basic structure of the RJ45 network connector always includes three parts.

  1. the contacts;
  2. insulation;
  3. the shielding case (depending on species maybe).

The Contacts

The contacts of the RJ45 network connector is the core functions of the parts for electrical connection. Usually, the contact pair composed of male and female contacts are mated to complete the electrical connection.

The positive contact of rigid parts, which shape is cylindrical (round pins), square column (square pin) or flat-shaped (inserts). Positive contacts generally made of brass, phosphor bronze. I.e.

As to the negative socket contact, the contact is part of the key, it relies on an elastic structure with the pin insertion timely elastic deformation force of the elastic contact member into close contact with the positive, to complete the connection.

The insulator

The insulator. Often referred insulator body, a base (base) or mounting plate (insert), its role is to make contact by location and spacing of the required arrangement, and to ensure that the contact between the RJ45 network connector member and the contact member and the housing insulation between. Good insulation resistance, voltage resistance and ease of processing are the basic requirements to select the insulating material.

The Housing

Housing. Also known as the shell (shield), the RJ45 network connector housing, which provides insulation and contacts built mechanical protection, and provides plug and socket plug timely alignment, and then secure the connector to the device.
