Stikinspektion
Den grundlæggende struktur afstik
Stiks are parts of electronic equipment that connect circuits to transmit current and are irreplaceable. The basic structure of the stikkan opdeles i fire dele: kontakt, isolator, skal og tilbehør.Med samfundsudviklingen og teknologiske fremskridt,stiks are playing an increasingly important role in various fields. In order to ensure their safety, durability and other performance, it is essential to test stiks. Generally speaking, the testing standards for stiks mainly include insertion and removal force, insulation resistance, durability, withstand voltage, contact resistance, vibration, and mechanical shock. The details are as follows:
1. Stikindsættelseskraft test.
2. Stik insulation resistance test
3. Stik durability test.
4. Stik withstand voltage test.
5. Stikkontaktmodstandstest.
6. Stik vibration test.
7. Stik mechanical shock test.
Stik productinspektion
Stik product inspection requirements mainly cover appearance, quality and performance.
1. Strukturstørrelse: Der er visse krav til formen og størrelsen af formen og forbindelsen tilstik has space restrictions. For example, the single-board stik cannot contact other parts, so the inspection of the structure size is the most important.
2. Reliability: The reliability of the connecting parts is related to the signal connection strength of the stik, and the reliability is a necessary inspection item for the performance inspection of the stik.
3. Afskærmning: Afskærmningseffekten afstiker også blevet mere og mere opmærksom. Afskærmningseffekten kan opnås ved at forbinde metalskallen påstik with the shielding layer, or wrapping the plug part of the stik with copper, and the shielding layer of the cable The copper sheets are welded together to act as a shield.
4. Versatility: When choosing stiks, try to choose general objects, which can reduce supply risks and costs, and reduce material types.
5. Holdbarhed: Holdbarheden afstikafspejles i dets evne til at tilpasse sig komplekse miljøer. Almindelige inspektionsindikatorer omfatter høj temperaturbestandighed, lav temperaturbestandighed, saltspraybestandighed og korrosionsbestandighed.
6. Impedance matching: The RF signal of the stik has high requirements for impedance matching. Impedance mismatch will cause signal reflection and affect signal transmission.
