LBT-1115 Socket Pull-Out Force Testing Device

Verify that the maximum force required to remove the plug from the socket and the minimum force required to withdraw a single‑pole pin from the receptacle assembly fall within the limits specified by the standard. Test objective: The insertion–withdrawal force test ensures that the structural plug of an electrical accessory does not become so difficult to remove due to excessive insertion force that it impairs user convenience. Durability testing involves repeatedly performing insertion–withdrawal cycles; after prolonged use, the plug must continue to meet the specified insertion–withdrawal force requirements and remain securely seated in the socket. Test sample scope: Sockets for household or similar applications.

LBT-1124 Plug (Pin) Insulating Sleeve Abrasion Resistance Tester

Test the wear resistance of the insulating sleeve on the plug pin. Structure: The apparatus consists of a horizontally mounted crossbeam and a linearly moving clamp holder. Function: At the end of the crossbeam is a U‑shaped head formed by a 1 mm‑diameter steel wire; the two ends of the U are vertically fixed to the crossbeam, with a straight working section of 6 mm along the base of the U. The 6‑mm straight base of the U‑shaped wire is pressed against the insulating sleeve of the plug pin, while an electric motor drives the clamp holder—carrying the plug—to perform reciprocating linear motion, thereby subjecting the wire to frictional contact with the insulating sample.
