The LS-B10 Apparatus for Abrasion Test on Insulating Sleeves of Plug Pins is designed and manufactured in strict accordance with Clause 24.8 and Figure 28 of GB/T 2099.1, “Plugs and Sockets for Household and Similar Purposes—Part 1: General Requirements” (IEC 60884-1:2022、条項23.2、図31）。

It is primarily used in electrical product quality inspection laboratories, the quality control departments of manufacturers of plugs, sockets, and electrical accessories, third-party testing organizations, and for import and export product inspections.

1.2 機器構成の検証

1.2.1開梱

When unpacking the device, handle it gently to avoid scratching the outer casing with sharp tools. After unpacking, first inspect the exterior of the device to ensure there is no visible deformation or dents, and that the buttons are not damaged or loose. If you notice any abnormalities with the device or its accessories, do not turn it on. Please contact us immediately.

2.安全上の注意

2.1 電気安全

Before connecting the power cord, verify that the supply voltage is AC 220V ±10% and the frequency is 50 Hz or 60 Hz. You must use a three-prong outlet with a protective ground, and the protective ground resistance must be ≤4 Ω. Never cut or disconnect the protective ground wire, as doing so poses a risk of electric shock.

2.2 環境安全

Do not use this equipment in environments with flammable or explosive substances, strong electromagnetic interference, high temperatures and humidity, or excessive dust levels. Place the equipment on a level, stable surface, leaving at least 0.5 m of operating space around it. Operating environment: temperature 5°C to 35°C, humidity ≤65% RH.

2.3 操作手順

During the test loading process, do not reach into the area of the clamps or the motor drive mechanism to prevent pinching injuries; test specimens must be securely clamped, as specimens falling out or weights dropping during the test may damage the equipment; it is strictly prohibited to disassemble the equipment’s drive mechanism or replace weights with non-original ones.

4. Wear Resistance Test for Plug Insulation Sleeves

4.1 サンプルの準備

Select finished plugs that are intact, undamaged, and have not undergone aging tests. The test must be conducted on one prong of each test specimen.

4.2 Sample Installation and Commissioning

Refer to the standard diagram in Section 3.1 to install the test specimen. Press the “Start Test” button to begin the test, observe the wire’s friction travel, and adjust the position of the connector so that approximately 7 mm of the 9 mm wire travel is covered by the insulating sleeve. Once adjusted, press the “Stop Test” button, then press the “Reset” button to clear the count.

4.3 Set Parameters and Start the Test

説明書	お願い
①	Press the counter setting button, then use the up and down buttons and the directional buttons to change the number of settings; according to the standard, the number of tests must be set to 20000.
②	Press the Reset button to clear the current test data.
③	Press the “Start Test” button to begin the test.
④	During the test, observe the condition of the specimen and the steel wire. If any abnormalities are detected, press the “Stop Test” button, make the necessary adjustments, and then retry.
⑤	When the test is complete, the motor stops rotating; check the current test count to confirm that the test has been completed.

4.4 試験結果の評価

After testing, the plug should show no damage that could compromise safety or affect future use; in particular, the insulated sheath should not be worn through or wrinkled.

5. 機器の日常的なメンテナンスと手入れ

5.1 Daily Maintenance After Shutdown

At the end of each day’s testing, clean dust and specimen debris from the equipment surfaces, and keep the clamps and slide rails clean and free of debris; check the steel wire for looseness or deformation; if it is deformed or damaged, replace it.

5.2 Weekly Routine Maintenance

Apply a small amount of specialized lubricating grease to the equipment’s guide rails, drive screws, and bearings to ensure smooth, jam-free operation.

5.3 Maintenance During Long-Term Storage

After powering down and cleaning the equipment, apply rust-preventative oil to important components such as bearings, drive screws, clamps, and weights to prevent rust and deformation. Cover the entire unit with a dust cover and store it in a dry, well-ventilated warehouse. Power on the equipment for 30 minutes each month to prevent moisture damage to the components.

5.4 校正間隔の要件

機器の測定精度と動作信頼性を確保するため、定期的に認定された第三者計測機関に送付して校正を受けることを推奨します。推奨される校正間隔は12ヶ月です。具体的な校正間隔は、使用頻度、環境条件、および品質システム要件に基づいてユーザーが決定できます。

6. 一般的な問題のトラブルシューティングと解決

障害症状	考えられる原因	手順
The device did not respond after the test was started.	Loose power cord, blown fuse	Check the input power supply and power cord connections; check the fuse on the front panel of the device; if it is blown, replace it with a fuse of the same rating.
