Multi-Movable socket – Outlets Mechanical Strength Testing Device

1. Pemahaman Dasar tentang Peralatan

1.1 Properti Dasar

This device is intended for specialized testing of the mechanical strength of portable plugs for household and similar uses.

It is primarily used in electrical product quality inspection laboratories, the quality control departments of portable power strip manufacturers, third-party testing organizations, and for the inspection of products entering or leaving the country.

1.2 Standar yang Berlaku

Strictly in accordance with Clause 24.10 and Figure 29 of GB/T 2099.1-2021 “Plugs and Sockets for Household and Similar Uses—Part 1: General Requirements” (Clause 24.10 of IEC 60884-1:2022, Figure 32).

Conduct mechanical strength tests on portable power strips in accordance with the specified drop height, angle, and number of drops.

2. Tindakan Pencegahan untuk Penggunaan

2.1 Operational Environment Safety Requirements

Operating environment temperature: 10°C to 35°C; relative humidity: 45% to 75%; no condensation, no corrosive gases, and no dust or airborne particles.

Letakkan perangkat di atas meja kerja yang rata dan stabil, sisakan setidaknya 30 cm ruang kerja di semua sisi, dan jauhkan dari sumber getaran.

2.2 Pedoman Keselamatan untuk Operator

During testing, no unauthorized personnel are permitted to enter or exit the test area, and no unrelated items may be placed in the area that could interfere with the test. Operators must securely clamp the flexible cable in the fixture to prevent it from loosening or falling during the test. It is strictly prohibited to use the equipment for non-standard tests to avoid equipment damage and safety incidents.

4. Mechanical Strength Testing of Portable Power Strips

4.1 Perlakuan Awal Spesimen Uji

Select the portable power strips to be tested, discarding any nonconforming samples with surface dents, cracks, or obvious deformation, and ensuring they have not undergone any destructive testing.

4.2 Penjepitan Sampel

See Figure 4-1 (image taken from the IEC standard). Secure the flexible cable to the equipment fixture; the length of the flexible cable between the fixture and the receptacle is 2250 mm.

4.3 Proses Pengujian

As described in Section 4.2, secure the free end of the flexible cable to the equipment fixture, hold the portable outlet test specimen, and position the flexible cable horizontally. Then drop the specimen onto a concrete floor 8 times. After each drop, rotate the flexible cable 45° at the secured end.

4.4 Interpretasi Hasil Tes

After the test, the test specimen shall not exhibit any damage within the range specified in the standard; in particular, no components shall become loose or detach.

Note: Minor scratches and dents that do not affect protection against electric shock or ingress of harmful water may be disregarded.

5. Prosedur Pasca-Ujian

5.1 Reset Perangkat

Remove the flexible cable after the test is complete. When the equipment is not in test mode, do not leave the flexible cable clamped in the fixture for extended periods of time.

5.2 Persiapan Sampel

Pisahkan sampel yang lulus dan gagal uji, beri label dengan jelas, dan hindari mencampurnya.

5.3 Membersihkan dan Merapikan Lokasi Pengujian

Use a lint-free, soft cloth to wipe dust and debris from the surfaces of fixtures, brackets, and equipment. Tidy up the test area and remove any debris generated during the test.

6. Perawatan dan Pemeliharaan Rutin

6.1 Pemeliharaan Reguler

Apply rust-preventive oil to the clamps and brackets every three months to prevent metal corrosion; apply a small amount of neutral grease to the bearings to prevent them from seizing up.

6.2 Persyaratan Interval Kalibrasi

To ensure the accuracy and reliability of the device, it is recommended that it be sent periodically to a qualified third-party metrology institution for calibration. The recommended calibration interval is 12 months. The specific calibration interval may be determined by the user based on frequency of use, environmental conditions, and quality system requirements.

7. Pemecahan Masalah dan Penyelesaian Masalah Umum

Gejala Kesalahan	Kemungkinan penyebab	Prosedur
Changes in the Center Height of the Fixture	Loosening of mounting screws due to vibration during transport or prolonged use	The fixture position is adjustable; recalibrate and secure the fixture’s center height to 750 mm according to standard dimensions.
The fixture jerks when rotating	Dust buildup in bearings, insufficient lubrication, foreign objects lodged in bearings	Try again after removing dust from the bearings, replenishing the lubricating grease, and clearing any foreign objects from the clearances.
