Electronic connectors are mainly divided into two categories according to their connection method: DIP category (e.g. PCI 120P): these connectors are usually soldered with solder soldering technology and are suitable for applications that require large insertion and extraction forces or need to support multiple pins.SMT category (e.g. MINI PCI EXPRESS): Surface mount technology (SMT) connectors for miniaturized, high-density electronic product designs, such as interfaces on modern motherboards. According to the appearance of the form, electronic connectors can be divided into: external type includes: interface: such as I / O connectors, such as D-SUB (serial port), USB, 1394, etc.. Card type: such as SD card, SIM card, NEW CARD and so on. Jacks: such as RJ11 (phone line), RJ45 (network cable), etc. Other types: such as SCSI interface, DVI interface, etc. Internal types include: BTB (board-to-board): connectors between two circuit boards. WTB (wire-to-board) and WTW (wire-to-wire): used to connect cables and circuit boards. FPC (pin-type): such as ZIF (Zero Insertion Force) sockets, commonly used for memory and HDD interfaces. Edge Card: such as AGP, PCI. Commonly found in expansion slots on computer motherboards.
Connector knowledge The basic properties of connectors can be divided into three main categories: namely, mechanical properties, electrical properties and environmental properties. Another important mechanical properties is the mechanical life of the connector. Mechanical life is actually a durability (durability) indicators, in the national standard GB5095 called it mechanical operation. It is an insertion and a pull-out for a cycle, in order to specify the insertion and pull-out cycle after the connector can normally complete its connection function (such as contact resistance value) as the basis for judgment. Mechanical properties of the connection function, insertion and extraction force is an important mechanical properties. Insertion force is divided into insertion force and pull-out force (pull-out force is also known as separation force), the two requirements are different. In the relevant standards have the maximum insertion force and minimum separation force provisions, which indicates that, from the point of view of the use, the insertion force should be small (so that there is a low insertion force LIF and no insertion force ZIF structure), while the separation force is too small, it will affect the reliability of the contact. Connector insertion and extraction force and mechanical life with the structure of the contact parts (the size of the positive pressure) the quality of the contact part plating (coefficient of sliding friction) and the contact parts of the arrangement of dimensional accuracy (alignment). 2. Electrical properties of the connector's main electrical properties include contact resistance, insulation resistance and electrical strength
Connector knowledge of the basic performance of the connector can be divided into three main categories: namely, mechanical properties, electrical properties and environmental performance. Another important mechanical properties is the mechanical life of the connector. Mechanical life is actually a durability (durability) indicators, in the national standard GB5095 called it mechanical operation. It is an insertion and a pull-out for a cycle, in order to specify the insertion and pull-out cycle after the connector can normally complete its connection function (such as contact resistance value) as the basis for judgment. 1. Mechanical properties of the connection function, insertion and extraction force is an important mechanical properties. Insertion force is divided into insertion force and pull-out force (pull-out force is also known as separation force), the two requirements are different. In the relevant standards have the maximum insertion force and minimum separation force provisions, which indicates that, from the point of view of the use, the insertion force to be small (so that there is a low insertion force LIF and no insertion force ZIF structure), while the separation force is too small, it will affect the reliability of the contact. The insertion and extraction force and mechanical life of the connector are related to the structure of the contacts (magnitude of positive pressure) the quality of the plating on the contact area (sliding friction coefficient
I'm not sure what you mean by the specifications of the general specifications are to see the pitch size of 0.5, 0.8, 1, 1.25mm But if you are referring to the type of distinction there are sub-upper connection type lower connection type direct insertion type patch type, patch there are sub-horizontal sticker, direct sticker
Connector, that is, CONNECTOR, also known as domestic plugs, plugs and sockets. Generally refers to electrical connectors. That is, the device that connects two active devices to transmit current or signal. It is widely used in aviation, aerospace, defense and other military systems.
