The performance and role of connectors in automotive systems

 Whether in traditional cars or new energy cars, automotive electrical connectors are valued by engineers. Because it plays an indispensable role in the normal driving of a car. Let’s talk about the role and performance of automotive electrical connectors today.

Generally speaking, in order to ensure safer driving of the car, the choice of car connector must be reliable. How to determine this reliability, that is to ensure that the electrical connector in the process of use, the performance of the sealing and spark prevention is stable. Moreover, when the electrical connector is working, it must have temperature control performance and display shielding performance.

Regarding the sealing performance of automotive electrical connectors, it is not only aimed at waterproof sealing performance. The international standard specification for closedness of automotive electrical connectors is IP67, which is also the highest specification for closedness in the industry. According to the different parts of the car, there will be different waterproof requirements. However, the IP67 standard has become the choice of many automobile manufacturers, which can better ensure the airtight performance of automobile electrical connectors.

The power supply is also the most important source of energy in the driving of a car. It is not only related to the normal operation of the engine, but also responsible for the use of all power sources during driving. The car electrical connectors are also divided into different car power systems, such as Between the male end connector and the device, between the female end connector and the cable, between the male end connector and the cable, and between the female end connector and the cable, these four types have certain airtight spaces to implement.

In the realization of the sealing performance of the automotive electrical connector, the sealing ring is indispensable. The sealing ring can not only realize the fixing effect between different holes, but also realize the sealing effect. It can not only ensure the stable operation of automobile equipment, but also ensure the waterproof performance of automobile equipment during work. The material of the sealing ring is mostly silicone rubber, which is produced by liquid silicon and solid silicon after a certain chemical change.

In the driving of a car, electronic circuit technology plays an important role. Whether it is the control system of the car or the internal entertainment facilities, the electronic circuit technology provides the connection guarantee for the stable operation of the car in all aspects. In order to make the electronic circuit technology work better, automobile manufacturers have applied many shielding technologies to ensure the smooth progress of the work. Shielding technology can firstly protect the electronic circuit of the car, and secondly, it also plays a role in anti-interference and radiation to other parts. Specifically, there are two types of shielding technologies: inner shielding and outer shielding.

When using external shielding to protect automobile electrical connectors, two identical shielding shells are usually assembled together to form a shielding layer, and the length of the shielding layer can cover the entire length of the connector. Ensure that there is enough lock plate structure to ensure reliable installation of the shielding layer. In addition, the shielding material used must not only be electroplated, but also be treated to prevent chemical corrosion.

What are the RF properties of coaxial cable

图片
How much do you know about coaxial cable? When you talk about coaxial cable, you will talk about the RF properties of coaxial cable. Do you know what the RF properties of coaxial cable are?The  Konnra Connectors  engineer will focus on introducing the RF properties of coaxial cables to you. We hope that you can master the RF properties of these coaxial cables through our explanation. The RF properties of coaxial cable mainly include six aspects: characteristic impedance, parasitic capacitance, transmission loss, transmission delay, return loss and rated power. The specific contents are as follows: 1. Characteristic impedance of coaxial cable It is an equivalent parameter in theoretical calculation, which reflects the measurement of the resistance degree of RF signal transmission when the wire transmits RF signal, and reflects the signal loss and signal delay of the transmission line at the physical ...

The optical fiber connector

图片
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Basic introduction A connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss (<0.5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small. Introduction Optical fiber con...

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and...
