Penyambungpemeriksaan
Struktur asaspenyambung
Penyambungs are parts of electronic equipment that connect circuits to transmit current and are irreplaceable. The basic structure of the penyambungboleh dibahagikan kepada empat bahagian: kontak, penebat, cangkang, dan aksesori.Kenalan: Ia terdiri daripada hubungan lelaki dan kenalan wanita, dan sambungan elektrik selesai melalui penyisipan kenalan lelaki dan wanita. Kenalan adalah bahagian inti daripenyambung, yang terutamanya memainkan peranan sambungan elektrik.
Penebat: Ia dapat mengatur potongan kontak mengikut kedudukan dan jarak yang diperlukan, dan memastikan prestasi penebat antara bahagian kontak dan antara cangkang dan kepingan kontak. Penebat juga disebut alas dan plat pelekap, yang memerlukan bahan penebat mempunyai ketahanan penebat yang baik, menahan prestasi voltan, dan kemudahan pemprosesan.
Shell: As the outer cover of the penyambung, it mainly provides mechanical protection for the built-in insulating mounting board and pins.
Aksesori: Terdapat dua jenis aksesori struktur dan aksesori pemasangan. Aksesori struktur, cincin pengapit, cincin penyambung, pengapit kabel, pin penentu, pin panduan, cincin pengedap, gasket, dan lain-lain; aksesori pemasangan-skru, mur, skru, gelang spring, dll.
Dengan perkembangan masyarakat dan kemajuan teknologi,penyambungs are playing an increasingly important role in various fields. In order to ensure their safety, durability and other performance, it is essential to test penyambungs. Generally speaking, the testing standards for penyambungs mainly include insertion and removal force, insulation resistance, durability, withstand voltage, contact resistance, vibration, and mechanical shock. The details are as follows:
1. Penyambungujian daya sisipan.
2. Penyambung insulation resistance test
3. Penyambung durability test.
4. Penyambung withstand voltage test.
5. Penyambungujian rintangan hubungan.
6. Penyambung vibration test.
7. Penyambung mechanical shock test.
Penyambung productpemeriksaan
Penyambung product inspection requirements mainly cover appearance, quality and performance.
1. Ukuran struktur: Terdapat syarat tertentu untuk bentuk dan ukuran bentuk, dan hubungannyapenyambung has space restrictions. For example, the single-board penyambung 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 penyambung, and the reliability is a necessary inspection item for the performance inspection of the penyambung.
3. Perisai: Kesan pelindung daripenyambungjuga telah diberi perhatian dan perhatian. Kesan pelindung dapat dicapai dengan menghubungkan shell logam daripenyambung with the shielding layer, or wrapping the plug part of the penyambung with copper, and the shielding layer of the cable The copper sheets are welded together to act as a shield.
4. Versatility: When choosing penyambungs, try to choose general objects, which can reduce supply risks and costs, and reduce material types.
5. Ketahanan: Ketahanan daripenyambungtercermin dalam kemampuannya untuk menyesuaikan diri dengan persekitaran yang kompleks. Petunjuk pemeriksaan biasa merangkumi rintangan suhu tinggi, rintangan suhu rendah, rintangan semburan garam, dan ketahanan kakisan.
6. Impedance matching: The RF signal of the penyambung has high requirements for impedance matching. Impedance mismatch will cause signal reflection and affect signal transmission.
