Description

Backboard connector plug
Technical Field
The invention relates to the technical field of connector equipment, in particular to a backboard connector plug.
Background
The connector is also called a connector. Also referred to as contacts and sockets, are commonly referred to as electrical connectors. I.e., devices that connect two active devices, transmit current or signals, the basic performance of a connector can be divided into three general categories: i.e. mechanical properties, electrical properties and environmental properties. Another important mechanical property is the mechanical life of the connector. The mechanical life is in fact a durability indicator, which is called mechanical operation in national standard GB 5095. It uses one insertion and one extraction as one cycle, and uses whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and extraction cycle as judgement basis.
1. Mechanical properties in terms of the connection function, the insertion and extraction forces are important mechanical properties. The insertion and extraction forces are divided into insertion force and extraction force (extraction force is also called separation force), and the requirements of the two are different. In the relevant standards, a maximum insertion force and a minimum separation force are specified, which means that from a use point of view the insertion force is small (and thus a low insertion force LIF and a no insertion force ZIF are constructed), whereas a separation force that is too small affects the reliability of the contact. The plug force and the mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact part of the structure (positive pressure and positive pressure) of the contact part and the arrangement dimensional precision (alignment degree) of the contact part;
2. electrical performance the main electrical performance of the connectors include contact resistance, insulation resistance, and electrical resistance. (1) High quality electrical connectors with contact resistance should have low and stable contact resistance. The contact resistance of the connector varies from a few milliohms to tens of milliohms; (2) the insulation resistance measures an indicator of insulation performance between electrical connector contacts and between contacts and housing, which is on the order of hundreds to thousands of megaohms; (3) the dielectric strength or withstand voltage and dielectric withstand voltage are the capability of representing the withstand rated test voltage between the contact pieces of the connector or between the contact pieces and the shell;
3. the common environmental performance comprises temperature resistance, moisture resistance, salt fog resistance, vibration resistance, impact resistance and the like, (1) the highest working temperature of the current temperature-resistant connector is 200 ℃ (except for a few high-temperature special connectors), and the lowest temperature is-65 ℃. Since the electrical current generates heat at the contact point when the connector is in operation, resulting in a temperature rise, 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 point. In some specifications, the highest allowable temperature rise of the connector at rated operating current is specified; (2) the penetration of moisture and humidity can affect the insulation properties of the connection h and rust the metal parts. The constant humidity and heat test conditions are that the relative humidity is 90% -95% (up to 98% according to the product specification), the temperature is +40+/-20 ℃, and the test time is 96 hours at least according to the product specification. The alternating damp-heat test is more severe; (3) when the salt spray resistant connector works in an environment containing moisture and salt, galvanic corrosion can be generated on a surface treatment layer of a metal structural part and a contact piece of the salt spray resistant connector, and physical and electrical performances of the connector are affected. In order to evaluate the ability of an electrical connector to withstand such an environment, a salt spray test was prescribed. The connector is hung in a temperature-controlled test box, sodium chloride solution with specified concentration is sprayed out by compressed air to form salt fog atmosphere, and the exposure time is specified by product specifications and is at least 48 hours; (4) vibration and shock resistance is an important property of electrical connectors, particularly in special application environments such as aviation and aerospace, rail and road transportation, which is an important indicator for testing the robustness of the mechanical structure and the reliability of electrical contacts of electrical connectors. There are clear regulations concerning the test methods. The peak acceleration, duration and pulse shape of the impact should be specified in the impact test, as well as the time at which the electrical continuity is interrupted.
The back board connector is a connector commonly used for large-scale communication equipment, ultra-high performance servers, huge computers, industrial computers and high-end storage equipment, and mainly is used for connecting a single board with a back board, the single board and the back board form a 90-degree vertical structure, high-speed differential signals or single-ended signals are transmitted, and large currents are transmitted.
