1.How to choose a proper waterproof connector?

Connectors are electronic parts that connect the flow of power and electrical signals. electrical connectors generally refers to  a component that connects two active devices to transmit current or signals. As the key component of current or signal connection, connector is an important part of industrial system. So how to choose a suitable connector?

The first factor to consider is the pin. Because pins and pin spacing are the fundamental basis for choosing a connector. The number of pins selected for the connector depends on the number of cable cores to be connected. These cores are generally used for conducting currents and signals. For some male and female connectors, as shown below, 2Pin 3Pin 3Pin 4Pin 5Pin 6Pin, etc. The multiple options for these male and female connectors allow a larger applied space.
It is suitable to select connector pins as required. When choosing the connector, special attention should be paid to the insulation injection molding material of the connector, which may be deformed by heat , resulting in that The middle of the connector is raised, and the pins are weak fixing.

The second factor to consider is the electrical performance of the connector. The electrical properties of connectors include working current, contact resistance, insulation resistance, and electrical strength. when connecting to equipment. Pay attention to the working current of the connector. If the rated current is exceeded, it will cause abnormal heat, smoke and fire, which will damage the machine and even lead to accidents.

The third factor to consider is the environmental performance of the connector. Connector environmental performance mainly includes temperature resistance, humidity resistance, salt spray resistance, vibration resistance, impact resistance and so on. Users can select according to the specific application environment.

For example, If the application environment is humid, the humidity and salt spray resistance of the connector is required to avoid corrosion of the metal contacts of the connector. While in the field of industrial control, the anti-vibration and impact performance of the connector is required to avoid the connector falling off in the vibration process.

The fourth factor to consider is the mechanical properties of the connector. The mechanical properties of the connector include insertion force, mechanical fool-proofing, etc. Mechanical fool proof design is very important to the connector, once inserted in reverse, is likely to cause irreversible damage to the circuit! Of course, this is for positive and negative discrimination.

And the insertion force is divided into insertion force and separation force. Generally, you can ask the maximum insertion force and minimum separation force of the connector for reference. From the perspective of use, the insertion force should be small, and the separation force should be large. If the separation force is too small, the contact reliability will be reduced. However, for connectors that often need to be inserted and removed, too much separation force will increase the difficulty of pulling out and reduce the mechanical life. The required separation force increases the difficulty of pulling out and reduces the mechanical life of the connector.

2.Why You Should Use Waterproof Connector for Outdoor Lighting?

3.100 Waterproof Lighting Wire Connectors IP67/IP68 for Your Option

With the wide application of solar power generation, the international standard MC4/H4 connector is widely used in the connection between photovoltaic modules and module matrix as well as the connection of combiner box, inverter and other equipment. Direct current is transferred and stored between these components through connectors. What is solar system connector? What characteristics should PV connectors have? Here are 12 things solar system wire connector you should know about.

(1)A connector plug socket is a part of a circuit that connects multiple solar cell components into a system. A quick connector for a solar system is called a solar connector and has the feature that it is convenient for plug and remove.

(2)The role of the connector is very simple and easy to understand. We use it to bridge the line break, so that the current can flow, the electrical signal can be transmitted, and the whole circuit can function properly.

(3)The form and structure of the solar connector is  kaleidoscopic. With different application object, frequency, power, application environment, there are a variety of different forms of connector. MC4 connector is one of the most common solar connector.

(4)MC is the abbreviation of the words-multi-contact, 4 is the metal core diameter size inside the connector. The name of MC4 photovoltaic connector a combination of these two characteristics. Solar connector is rising with the mature application of solar energy. Based on the demand of collecting current from solar panel, the world‘s first real sense of photovoltaic connector MC3 is developed by a company named Multi-Contact. It is prefixed by the brand name and suffixed by the metal core diameter. Many of the later solar connectors that claimed the MC4 used this naming rule.

(6)The long-term environment faced by solar connector. because PV systems are exposed to wind, rain, hot sun and extreme temperature changes for a long time, the connectors using here must be able to adapt to those harsh environments. Photovoltaic connector should not only be waterproof, high temperature resistance and UV resistance weather proof , but also to achieve touch protection, high load current capacity and high efficiency, etc. in the meantime,low contact resistance is also an important consideration index. These all have to be taken into account when choosing a PV system connector, as it will be throughout the PV system life cycle.

(7)Solar system connectors for PV systems should conduct well and have contact resistance not greater than 0.35 mΩ.

(8)Solar system connectors used in photovoltaic systems are required to have sufficient safety features to ensure the safety performance of solar cell modules.

(9)PV connectors used in solar systems are required to have a protection class of IP68. Because the solar equipment is used outdoors in a variable climate, the entire solar system should be equipped with high protection grade connectors.

(10)Solar system connectors used in photovoltaic systems require a solid and reliable connector structure. If the solar connector is correctly inserted, the connection between the male and female terminals should not be less than 80N.

(11)MC4 connector belongs to single core connector.This connector has male head, female head difference.What’s more,MC4 connectors have good sealing, convenient insertion, repair, maintenance and many other advantages.

Solar connectors, though small, are important in photovoltaic power systems. If the connector is in poor working condition, the internal resistance of the DC side will increase, which will lead to the decrease of power generation efficiency of the power station; if the connector is in poor contact, it will heat up or even burn the connector, which will lead to the burning of the combiner box and inverter, or even cause a large area fire.

4.What to Know About Automatic Equipment Cable Connector?

The cable and connector used by the automatic equipment are in a very high demand, which is not only required to has strong signal transmission capacity, but also has good wear resistance and other characteristics, so as to ensure the equipment a durable guarantee and a long serve life.find cable and connector for your automatic equipment?  WeiChat is your reliable electrical connector supplier.

Automation equipment has high requirements for cables and connectors. Cable connectors not only require strong signal transmission capacity, but also have good wear resistance, transmission stability and other characteristics. When these characteristics are available at the same time, the automation equipment can run better and exert its mechanical properties to ensure the high efficiency of production.

Cable connector of automation equipment is a kind of special connecting terminal, many enterprises do not have so great strength in research and development, production and supply. if you are looking for a suitable cable connector for automation equipment, WeiChat is a not bad choice for you.

Beforehand, it is believed that many people do not understand the automation equipment cable connector, so let‘s have a rough look at what requirements of the automation equipment connector?

(1)Strong signal ability
Automation equipment is mainly according to the set program issued by the central command to work. The signal from the center to the device execution end, the main dependence is the cable connector. If the cable connector is of good quality, then the transmission signal is short and accurate, but if the cable is of poor quality, it will definitely affect the signal transmission and will not allow the automation equipment to work immediately and execute the right command.

(2)Stable signal transmission
If the connector end quality is not good, the signal transmission may be interrupted, so that the automatic equipment cannot run continuously. Therefore, in the process of signal transmission, especially in the place of continuation, the selection of cable connector deserves special attention.

(3)Good wear resistance and flexibility
In addition to the connector, the cables connected to the connector also have certain requirements.good wear resistance, good rotation property and good flexibility are the requirements that automation equipment cables must own. Because the cable will be damaged after long-term use.If the wear resistance of the cable is not good, it will affect the internal stranded wire and the robot can not be used normally, meanwhile it will also produce safety risks. Therefore, the robot cable selected must have good wear resistance.The cable and connector are a whole, which together affect the signal transmission of the whole line.

(4)Long service life
The service life of the automation equipment connector should be long. Only when the cable connector with a long service life that  is can help to save resources and improve work efficiency. Long-life cable connectors are preferred for enterprises.

If the connector of the automation equipment can meet the four requirements above,  such a connector will be right for the use of automation equipment. On the other hand, if the above requirements cannot be met and the inferior connector is used, it will not only affect the use of the automation equipment, but also cause damage to the equipment, which will lead to equipment failure.
