What are the basic performance types of strip connector and RF connector? ——Ethernet network transformer

Mechanical equipment performance in terms of connection function, plug force is the key mechanical equipment performance. The pull-out force is divided into pull-in force and pull-out force (pull-out force is also called separation force). The provisions of the two are different. In relevant codes, there are requirements for large insertion force and minimum separation force, which shows that from the perspective of application, the insertion force is small (and then there are structures of low insertion force LIF and non insertion force ZIF), and if the separation force is small, it will endanger the credibility of contact.

Another key performance of mechanical equipment is the service life of mechanical equipment of connector. In fact, the service life of mechanical equipment of micro pulse network filter is a kind of durability index value, which is called the actual operation of mechanical equipment in the national standard gb5095. It should take one insertion and one extraction as a cycle system, and take whether the connector can normally perform its connection function (such as contact resistance value) after the required insertion and removal of the cycle system as the evaluation basis.

The pulling force and service life of the mechanical equipment of the connector are related to the coating quality (rolling friction index) of the contact structure (positive working pressure size) of the contact position and the precision (directivity) of the contact sequencing specification.

The key electrical performance of electrical connector includes contact resistance, grounding resistance of micro network signal transformer and electrical compressive strength.

① The electrical connector with high quality 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 grounding resistance shall take into account the index values of the performance of the insulation layer between the contact parts of the electrical connector and between the contact parts and the shell, with the magnitude varying from over 100 megohm to over 1000 megohm.

③ The electrical compressive strength, or working voltage and material compressive strength, is the working ability of qualitative analysis of the rated experimental working voltage of the resistance between the connector contact or between the contact and the shell.

④ Other micro network filter price electrical performance EMI leakage attenuation coefficient is the actual effect of EMI shielding of the comment connector, and EMI leakage attenuation coefficient is the actual effect of EMI shielding of the comment connector, which is generally detected in the frequency range of 100MHz ~ 10GHz.

As for the frequency connector, there are also electrical indexes such as impedance, insertion loss, transmission coefficient and VSWR.

Because of the development trend of electronic information technology of micro network communication transformer, in order to connect and transmit high-speed and large digital differential signals, a new type of connector, namely high-speed data signal connector, micro Ethernet RJ45 connector, has appeared. In terms of electrical performance, in addition to impedance, there are also some new electrical index values, such as crosstalk, transmission delay time（ Delay, skew, etc
