What is the working principle of the M8 connector?

I believe many people are no strangers to the M8 connector. Let me introduce you in detail today. The M8 connector and cables are two or more containers that communicate with each other below the liquid level. The connector with the same liquid and equal pressure on the liquid surface has the same liquid level.

(1) The M8 connector connection line contains the same liquid, but the pressure on the liquid level is not equal, the pressure difference of the liquid level is equal to the pressure difference caused by the difference in the liquid level between the two containers of the communicating device.

(2) The pressure on the liquid level of the M8 connector cable is equal, but there are different liquids that are not mixed with each other. The height of the two liquid surfaces is inversely proportional to the liquid density from the interface.

The M8 connector cable principle has a wide range of applications in engineering. For example, various liquid level meters (water level gauges, oil level gauges, etc.), mercury vacuum gauges, liquid column air pressure gauges, differential pressure gauges, etc., are all made by applying the principle of the connected device.

By understanding the definition and working principle of the M8 connector and cable, it can help us better understand and develop the connector market.

Advantages of Renhotec Technology M8 Connector:

1. Easy to repair. If an electronic component fails, the failed component can be quickly replaced when the connector is installed;

2. Improve the production process. The connector simplifies the assembly process of electronic products. It also simplifies the mass production process;

3. Easy to upgrade. As technology advances, components can be updated with connectors, replacing old ones with new, more sophisticated components;

4. Improve design flexibility. The use of connectors gives engineers greater flexibility when designing and integrating new products, as well as when building components with components.

Hope the above contents about the M8 connector will help you. Welcome to continue to pay attention to Shenzhen Renhotec Technology Electronics Co., Ltd., consult our engineers [email protected],and visit our website www.renhotecpro.com

What are the connection forms of the connector?

There are four main types connections:

1. Threaded connection: Some types of connections are often used for contacts with larger dimensions and connector plugs that operate in a strong vibration environment. This type of connection can be fitted with a fuse that prevents loosening after the connection is completed. The connection form is reliable,but slow to connect and pull.

2. Bayonet connection: it is a reliable and rapid connection and separation form. Most of the electrical connectors of the 121 connection form have a visual display of the correct connection and locking and can be viewed from the small holes on the side of the electrical connector connection nut.

3. Plug and pull connection: is a multi-purpose connection form. When the plug and the socket of the electrical connector are connected and disconnected, the moving direction is usually a reciprocating linear motion, without twisting and rotating, and only a small working space is required to complete the loading and unloading. Common plug-in connections are available in either ball or pin configurations. Since the connection form has no mechanically labor-saving mechanism, once the insertion is mistaken, the mechanical resistance is significantly increased and can be found in time.

4. The cabinet connection: it is used for some electrical connectors on the equipment that need to be blindly connected to the frame, which can make the electrical equipment lighter and smaller, easier to maintain and more reliable. This type of connection makes it impossible for the operator to feel the connection. It is necessary to design an accurate positioning device to avoid forcibly connecting the mis-inserted connector plugs together, making mis-insertion impossible. Connector plugs are usually designed with a floating or resilient contact design to ensure proper connection.

What factors affect the contact resistance and reliability of the aviation plug PIN?

Contact material, vertical pressure, surface morphology, voltage and current usage can affect the contact resistance of the PIN pin of the aviation plug. Affected by the technical conditions of aviation plugs, the contact resistance indexes of the same type of mating contact parts made of different materials are different. For example, the contact resistance of the mating contact piece with a diameter of 1 mm, the copper alloy should not be greater than 5 mΩ, and the ferroalloy is ≤ 15mΩ.

Vertical pressure refers to the force generated by a surface in contact with each other and perpendicular to the contact surface. The number and area of ​​contact micro-dots will increase with the increase of vertical pressure, and the contact micro-point will also transition from elastic deformation to plastic deformation, thereby reducing the concentrated resistance, and the contact resistance will decrease as the concentrated resistance decreases.

Dust, rosin and oil stains will be deposited on the surface of the joint to form a loose surface. The surface of the film will contain particulate matter, which will carry particulate matter embedded in the microscopic pits on the contact surface, reducing contact. Area, increasing contact resistance, resulting in unstable performance; affected by physical adsorption and chemisorption, the surface of the contact point will deposit a fouling film, increasing contact resistance, resulting in unstable performance. In order to improve the performance and reduce the contact resistance, the aviation plug must have clean production environment conditions in the production and assembly environment, as well as a complete cleaning process and necessary structural sealing measures, and the storage and use operating environment should also be good.

When the voltage reaches a certain threshold, the contact film will be broken down, and the contact resistance will drop rapidly. However, due to the thermal effect, the chemical reaction in the vicinity of the film will accelerate the repair of the film.

How to meet the installation requirements of aviation plugs:

  1. Ordinary sockets should be installed in a dry, dust-free place.
  2. The socket should be installed firmly. Since the socket is always charged, the installation height of the wall-mounted socket is not less than 1.3m from the ground, generally 1.5-1.8m, and the concealed socket allows for low installation, but the height from the ground is not less than 0.3m.
  3. For the aviation plugs in the same place, the installation height should be the same, the height difference should be no more than 5mm, and the sockets installed in rows should not be larger than 2mm.
  4. Socket power cords for high-power household appliances such as air conditioners and electric water heaters should be arranged separately from the power cords of the lamps. The sockets should not be shared with other household appliances. The power cable should be directly led out from the distribution box or bus. The wires used are generally copper core wires with a cross section of not less than 2.5 mm. The air conditioner should be a copper core wire with a section of not less than 4 square meters.
  5. 5.Concealed socket should have a special box, the cover should be straight and close to the wall. Surface mounted aerial plugs are to be mounted on wooden pallets and secured with two wood screws.

Types and advantages and disadvantages of rubber insulators commonly used in aviation plug connectors

The most commonly used Plastic material are PBT, PPT, POM, ABS, and LCP. What are the characteristics of these five kinds of plastic material?

PBT is a thermoplastic and is one of the five most widely used engineering plastics. It has the advantages of good strength, heat resistance, low temperature resistance, chemical resistance, low water absorption, good gloss, good electrical properties and easy processing. It can withstand 230 ° C heat temperature, oxidation resistance and comprehensive performance. The disadvantage is molding shrinkage. Large and notched impact strength is low.

PDM, which belongs to the five general engineering plastics as well as PBT, is the hardest plastic material in thermoplastics. Its mechanical properties are one of the closest metal varieties in plastic materials, with low friction coefficient and good Stability, tensile strength, flexural strength, fatigue strength, abrasion resistance and electrical properties are all excellent, but they are susceptible to strong acid corrosion, poor weatherability and poor adhesion.

ABS is a general-purpose plastic, which has the advantages of good rigidity, good impact strength, heat resistance, low temperature resistance, chemical resistance, chemical stability, and good electrical properties. It can withstand 180 ° C heat temperature and has good flexibility.

PPT has excellent electrical properties, good dimensional stability, low friction coefficient, self-lubricating, low water absorption, chemical resistance, oil resistance, and can withstand 160 ° C hot temperature, if used in the production of aviation plug products. Its high temperature resistance can reach 250 ° C, which is higher than that of POM material. Its mechanical properties are stable tensile strength and tensile modulus are similar to nylon.
