What are the performance of the RF connector?

author:kingsignal time:2017/05/20

RF connector performance is mainly mechanical properties, electrical performance and environmental performance. Here we will detail about the relevant performance.

 

1.Mechanical properties

 

(1) insertion force

 

Mechanical performance In terms of connection function, the insertion force is an important mechanical property. Insertion force is divided into insertion force and pull out force, the two requirements are different. In the relevant standards have the maximum insertion force and the minimum separation of the provisions, which shows that from the use point of view, the insertion force is small, and the separation force is too small, it will affect the reliability of contact.

 

(2) mechanical life

 

Mechanical life is actually a durability indicator. It is a single insert and a pull out as a cycle to the provisions of the plug-in cycle after the connector can normally complete its connection function as a basis for judging.

 

2. Electrical performance

 

Electrical performance The main electrical performance of the connector includes contact resistance, insulation resistance and electrical strength.

 

(1) contact resistance

 

Contact resistance High quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to several tens of milliohms.

 

(2) Insulation resistance

 

Insulation resistance measures the insulation performance between electrical connector contacts and between the contact and the enclosure, which is of the order of several hundred megohms to several gigahertz.

 

(3) electrical strength

 

Dielectric strength or resistance to voltage, dielectric pressure, is to characterize the connector between the contacts or between the contact with the shell to withstand the rated test voltage capacity.

 

3. Environmental performance

 

Environmental performance Common environmental performance including temperature, moisture, salt spray resistance, vibration and shock.

 

(1) temperature

 

Temperature The current connector has a maximum operating temperature of 200 ° C and a minimum temperature of -65 ° C. As the connector works, the current at the contact point to generate heat, resulting in temperature rise, it is generally believed that the operating temperature should be equal to the ambient temperature and contact temperature rise and. In some specifications, the maximum permissible temperature rise of the connector at rated operating current is specified.

 

(2) moisture resistant

 

Moisture resistant moisture intrusion will affect the connection h insulation performance, and corrosion of metal parts. Constant humidity test conditions for the relative humidity of 90% to 95%, temperature +40 ± 20 ℃, the test time by product, at least 96 hours. Alternating hot and humid test is more stringent.

 

(3) salt spray resistance

 

Salt resistant connectors work in environments containing moisture and salt, and their metal structures and contact surfaces are likely to produce electrochemical corrosion, affecting the physical and electrical properties of the connector. In order to evaluate the ability of the electrical connector to withstand this environment, a salt spray test was specified. It is suspended in the temperature of the control box, with a specified concentration of sodium chloride solution with compressed air sprayed to form salt mist atmosphere, the exposure time by the product specification, at least 48 hours.

 

(4) vibration and shock

 

Vibration and Shock Resistance to vibration and shock is an important feature of electrical connectors that are particularly important in special applications such as aerospace and aerospace, railways and road transport. It is to test the robustness of electrical connectors and the reliability of electrical contact Of the important indicators. In the relevant test methods are clearly defined. The peak acceleration, duration, and impulse pulse waveforms, as well as the duration of electrical continuity, shall be specified in the impact test.
