IP67. IP68 is a well-known waterproof level, but after hearing IEC 60529, I am at a loss, not knowing what this series of numbers is. Next, let me take a look at what is the IEC 60529 standard. International Protection Marking (IEC 60529) is also called Ingress Protection Rating or IP Code. Sometimes called "waterproof grade" "dustproof grade", etc., it defines the degree to which mechanical and electronic equipment can provide protection against solid foreign body intrusion (including body parts such as fingers, dust, gravel, etc.), liquid infiltration, and accidental contact Protection ability. This standard focuses on providing users with more detailed product information, not just vague marketing vocabulary, such as "waterproof." However, the standard has not been publicly released. The number in the code indicates compliance with the conditions in the table below. When it does not meet any of the conditions, the digit is replaced by the letter ...

This standard lists objective, acceptance, and unfavorable conditions for different grades of products, and concession acceptance is also included. During the inspection, the inspector does not have to choose the level of product acceptance for assembly. This standard will provide the inspector with the level of product acceptance, the conditions are as follows:  1. Objective: This state is close to perfect. This is an ideal situation and cannot be achieved. It is not necessary to ensure that the assembly requirements of this level are met. 2. Acceptance: The conditions need not be perfect, but the product must maintain the integrity and stability of the assembly in the working environment. 3. Concession acceptance: The condition of concession acceptance is not to affect the composition, installation, function, or stability of the product. Conditions such as materials, design, operators, or machines do not meet acceptable standards or are defective products. Concession a...

During the production process, tool and equipment control is something every manufacturer must master. How to control tools and equipment? Each manufacturer must: 1. Select tools for crimping, thread cutting, peeling, binding, measuring, testing, and achieving the expected function in the prepared workplace. 2. Clean and proper maintenance tools and equipment. 3. Check the performance of the tool, using in cabling, to prevent tangible loss. 4. Prevent unidentified, defective, and unverified tools from entering the workplace. 5. There should be documents detailing the operating procedures and maintenance intervals for tool and equipment verification or setting. 6. Records shall be made on the effectiveness or functional tests of tools and equipment. According to domestic or foreign standards. The manufacturer must establish a verification system. This standard must include: 1. The measurement standard is suitable for tools that need to be glamorous and must be traceab...

The IPC standard is the most important standard document for electronic engineering personnel. It has very authoritative and enforceable regulations on the reliability, safety, standardization, and manufacturability of electronic equipment and systems. ​ This standard is an appearance acceptance standard related to cable assembly established by the Cable Assembly Association and the Electronic Connection Products Committee. If no standards for process inspection and finished product inspection are defined, IPC 620 can be used as the inspection standard document for the product alone. It establishes process control or defective products that allow repair/rework. This information suggests that it needs to be improved through statistical process control plans. IPC 620 mainly includes the following: conductor/cable preparation, measurement of cable assemblies and conductors, crimp terminals, insulation piercing connections, solder terminals, connector connections, compression/inject...

The selection of wire should be considered from the aspects of circuit conditions, ambient temperature, and mechanical strength. First. Circuit conditions: 1. Allowable current: Allowable current refers to the current value at normal temperature. The allowable current of the wire should be greater than the maximum current of the circuit. 2. The voltage drop of wire resistance: When the wire is long, use a wire with a large diameter to reduce the influence of resistance on the voltage. 3. Rated voltage and insulation: In use, the maximum voltage of the circuit should be lower than the rated voltage of the wire. 4. Signal shielding: When the signal level is small, it is susceptible to interference from noise signals. Shielded wires are often used to overcome the interference. Second. Environmental conditions: 1. Temperature: Temperature will make the insulation layer of the wire soft and hard and cause a short circuit. 2. Electrochemical resistance: Under normal circ...

Nylon tube is widely used by many automobile manufacturers in the world because of its advantages such as easy assembly, cleanness, anti-aging, and corrosion resistance. ​ For a car to achieve safe driving, it must have good braking performance, so the parts of the brake system are also called "security parts". Due to the very high requirements for nylon tubes used in automotive braking systems, it must be rigorously tested and researched before they can be used in automobiles. There are also strict requirements for the installation of nylon tubes in automobile brake systems: they must have good sealing performance and should be easy to disassemble, adapt to various weather and environments, and have good anti-vibration effects. When designing the joints of nylon pipes, the following two principles must be met: (1) Under the specified conditions, the pipe joints must have good sealing, and the pipe joints must meet the strength when the pipe fittings are pulled out; (2...

Nylon bellows tube Nylon bellows is a PA wire harness threading bellows developed with PA nylon as the raw material. It has good flexibility, resistance to twisting, good bending performance, and can withstand heavy loads. Good aging resistance, good mechanical vibration reduction ability, good sliding property, excellent wear resistance, good machining performance, used for precise and effective control, no creeping phenomenon, good anti-wear performance, good dimensional stability. The working temperature is -40℃-+125℃. PVC jacket PVC is a durable material that is not affected by corrosion or other forms of degradation. It can be easily converted into different forms so that it has obvious advantages in various industries. As a thermoplastic, it can be recycled and converted into new products in different industries. It also exhibits chemical stability, which is an important factor in the application of PVC products to different types of chemicals. Braided tube The braid...
