LBT-1108 Plug Pin Insulation Sleeve Abnormal Heat Resistance Test Apparatus

Description

Meets the standard:

Clause 28.1.2 and Figure 40 of GB 2099-2008

IEC 60884-1 Figure 40

Purpose:

Conduct thermal and flammability tests under abnormal temperature conditions on plugs equipped with insulating sleeves for the pins.

Simulation of insulating components that may be subjected to electrothermal stress and whose degradation could compromise the safety performance of the mating assembly.

Specimen range:

Plug pin insulating sleeve

Structure and Function:

According to the standard, the heat resistance and flame retardancy of the insulating sleeve on the test plug pin are tested.

Note: The plug pin insulation sleeve of the non‑normal heat test apparatus shall not sustain excessive damage when exposed to overheating and flame.

Technical Specifications:

1. Insulating plate: A flat, circular surface 5 mm thick, with a diameter twice that of the test specimen’s contact area, made of bakelite or epoxy laminate.

2. Metal Component B (Fixture): Length exceeds 20 mm; material is brass. Standard configuration includes three types: GB6A two‑pin, GB10A three‑pin, and GB16A three‑pin; customization available.

3. Gap between the insulating plate and metal part B: 3 ± 0.2 mm, ensuring air convection around the pins.

4. Thermocouple distance from the front surface of metal part B: 7 ± 0.5 mm

5. The pin on metal part B is inserted into the hole: the clearance is greater than 0.1 mm beyond the pin’s maximum cross-sectional dimension.

6. Equipped with a K-type thermocouple and an imported high-precision digital temperature controller.
