Main Functions And Advantages Of Connector
Connector is an important node for information transmission and conversion of electronic equipment. It is mainly used to connect the conductor of one circuit to the conductor of another circuit. Moreover, the connector also provides a detachable interface for the two circuit subsystems. When maintaining or upgrading components, there is no need to change the whole system, which not only improves the portability of components and the scalability of equipment, but also makes the design and manufacturing process more convenient and flexible.
1. The interconnection transmission performance of the connector changes the overall disadvantage of excessive space and spacing, and connects the combination of large space, so as to realize the unity of three-dimensional surface connection and plane.
2. The connector is simple and compact. Once a connection problem is found, it is very convenient for maintenance and replacement. Moreover, the connector can be upgraded quickly and the internal components can be renovated and replaced, which is more important for the cost saving and safety guarantee of the whole project.
3. The flexible design of the connector is also one of the main advantages of choosing it. The design of the connector is compact, easy to install and disassemble, and ensures its safety and integrity.
What Are The Commonly Used Materials For Connectors?
Nylon
There are two kinds of nylon materials, one is ordinary nylon material, the other is high-temperature nylon material. Ordinary nylon material has the advantages of excellent chemical resistance and high strength. The disadvantage is that the wettability of the material will lead to the decline of the electrical function of the connector; The advantages of high-temperature nylon material will have higher toughness and ductility than ordinary nylon material! The disadvantages are the same as that of ordinary nylon, and the cost will be higher than that of ordinary nylon!
PBT
The material characteristics of PBT are its excellent moisture resistance and high strength. At the same time, it also has excellent chemical resistance, and the disadvantage of PBT is that its cost will be higher than that of high-temperature nylon, and it is not suitable for surface mounting technology!
PCT
The characteristics of PCT material are its dimensional stability, high strength and excellent chemical resistance. The disadvantage is that it may break, and its cost will be higher than that of PBT.
PPS
The advantage of PPS material lies in its moisture resistance and excellent chemical resistance. The disadvantage is that it is more fragile than other plastic materials and has less color selectivity. In addition, its cost is higher than that of most thermoplastic plastic materials.
LCP
LCP material has many advantages. It has super moisture resistance, toughness and strength. It also has excellent chemical resistance. Moreover, it is very suitable for the thin wall of injection molded connector with instant noodles bonding technology. Its disadvantage is that the flexibility of LCP material is worse than that of other thermoplastic materials, and its color is less and the cost is higher.
Performance requirements for plastics used in connectors
Temperature resistance: Meet the maximum operating temperature and minimum temperature of the connector.
Because when the connector is working, the current generates heat at the contact point, causing a temperature rise. Therefore, it is generally believed that the operating temperature should be equal to the sum of the ambient temperature and the temperature rise of the contact.
Water absorbency: For connectors requiring #SMT, water absorption is an important indicator for #material #selection. Connectors are prone to defects such as blistering during the SMT process after absorbing water. The less absorbent the plastic from which the connector is produced, the longer the connector can be stored.
Mechanical properties: Connection performance
Connectors need to meet certain #pull-out force test requirements
Vibration and shock
Vibration and impact resistance are important properties of connectors. They are particularly important in special application environments, such as aerospace and rail transportation. They are important indicators of the robustness of the mechanical structure of the connector and the reliability of electrical contacts.
Electrical properties: Withstand voltage and insulation; CTI level 0-5, the smaller the value, the better.
Flame retardant properties: Under specific conditions of use, electrical flame retardant requirements should be met. Flame retardant properties range from HB to V0.
Environmental resistance: Common environmental performances include low temperature, constant humidity and heat, alternating humidity and heat, salt spray test, sulfur dioxide test, and hydrogen sulfide test.Other environmental properties of the connector include sealing (air leakage, liquid pressure), chemical resistance (resistance to specific chemical reagents), low air pressure, etc.
Processing performance: The fluidity of the material meets the #molding conditions, and the size is stable and the deformation is small.
A list of electrical or electronic devices using connectors would be long and varied both in function and construction. At the beginning of the list, both in function and construction, is an incandescent lamp. At the complex end of the list, both in function and construction, is a collection of computer servers interconnected to provide the immense functionality of a search engine.
The power connection consists of two sections the wall receptacle and the wall plug. This connection is a separable connection, the wall plug is separable from the wall receptacle to enable the lamp to be moved to different locations. The wall plug has two metal pins that are inserted into the wall receptacle and the wall receptacle contains two metal spring systems that are deflected as the pins are inserted. Two pins/receptacle springs are necessary to provide both input and output power connections. The force created by the deflection of the receptacle spring when a pin and the receptacle spring come in contact creates and maintains the metal-to-metal interface that enables the power, voltage and current, from the power source to be transmitted to the lamp. The properties of this interface will be discussed in detail later in this chapter, but it is worth noting at this point that creating and maintaining a metal-to-metal interface is the prime goal of connector design. In addition to this separable connection, there are two permanent connections. The wall receptacle is connected to the house wiring, usually by a mechanical connection.
Four Keys To Good Connector Care
Electronic engine control (EEC) systems are an increasingly popular option among operators of P&WC engines. These systems are extremely precise and reliable, but once in a while, a fault may be reported. Whether it’s a non-critical fault that doesn’t affect dispatch availability or a critical fault requiring immediate attention, the cause often lies with a connector in the engine and airframe electrical wiring harness.
Before re-connecting a connector, it should be cleaned thoroughly. As explained in detail in the engine maintenance manual, this is a multi-step procedure involving tasks such as rinsing the connector with alcohol, applying contact cleaner (deoxidizer) and so forth.
When re-attaching the connector after cleaning and maintenance, always follow the maintenance manual procedure carefully. One step in particular is easy to overlook but should always be carried out: applying a counter-load to the backshell while torqueing the connector ring using soft-jawed pliers or a mini-strap wrench. This ensures it’s as tight as possible and less likely to come loose accidentally.
Finally, as an insurance measure, André also recommends putting electrical insulation tape over the connector after it has been properly cleaned and tightened.
Factors to Consider in Connector Selection
Current carrying capacity: When selecting the connector for the power signal, pay more attention to the current carrying capacity of the connector, adopt a derating design, and pay attention to the insulation withstand voltage between the pins.
Structural size: The external size of the connector is very important. There are certain space restrictions for the connection in the product, especially the single-board connector, which cannot interfere with other components. Choose the appropriate installation method according to the use space and installation position (installation includes front installation and rear installation, installation and fixing methods include rivets, screws, collars or quick locking of the connector itself, etc.) and shape (straight, curved, T type, round, square).
Impedance matching: Some signals have impedance requirements, especially RF signals, which have stricter impedance matching requirements. When the impedance does not match, it will cause signal reflection, which will affect signal transmission. Generally, signal transmission has no special requirements on the impedance of the connector.
Shielding: With the development of communication products, EMC has been paid more and more attention. When choosing a connector, it needs to have a metal shell. At the same time, the cable needs to have a shielding layer. The shielding layer should be connected with the metal shell of the connector. To achieve the shielding effect, the injection molding method can also be used to wrap the plug part with copper skin, and the shielding layer of the cable and the copper skin are welded together.
Anti-mis-insertion: There are two aspects to prevent mis-insertion: on the one hand, the connector itself, which rotates 180 degrees, and the misaligned connection leads to wrong signal connection. Adjust the relative position relationship of the connectors to make the assembly unique; on the other hand, in order to reduce the types of materials, several signals use the same connector, at this time, it is possible to insert the A plug into the B plug, and you need to pay attention at this time. , if such a situation will cause serious consequences, the A and B interfaces must be selected as different types of sockets.
Reliability: The connector is used to connect the signal, so the connection part should be reliable (for example, surface contact is better than point contact, pinhole type is better than leaf spring type, etc.).
Versatility: In the selection process of connectors, it is necessary to choose common objects as much as possible, especially among products of the same series, the selection of connectors has strong versatility, reducing the types of materials, increasing the quantity and reducing costs, while reducing supply. cargo risk.
Use environment: When the connector is used in outdoor, indoor, high temperature, high humidity, salt spray, mold, cold and other environments, there are special requirements for the connector.
Locking function: In order to prevent the connector from falling off when mating and to ensure good contact, the connector needs to have a locking function.
Cost: Cost is also an important factor in the selection process. With the increasingly fierce market competition, the appropriate selection of connectors, the cost of the connector itself and the processing cost need to be comprehensively considered.
Availability: The supply of connectors will be affected by many factors. General-purpose connectors are better than non-universal connectors, and domestically produced ones are better than foreign ones.
Plugging frequency: The plugging and unplugging of the connector has a certain life. After the number of plugging and unplugging reaches the limit, the performance of the connector will decline. When some signal interfaces need to be plugged and unplugged frequently, more attention should be paid to the connection when selecting a connector. The number of times of plugging and unplugging the device.
Consideration of electrification: Choose a pin-type or female-type connector according to whether it is often electrified or not.
Comprehensive consideration: In the process of selecting connectors, various factors are not independent and often interact with each other. Therefore, we must comprehensively consider in the process of connector selection, select the most suitable connector, and choose whether it is good or bad. The product will be affected to different degrees at different stages.
