Low Energy Pendulum Impact Test Apparatus For Test Household Plugs And Sockets IEC60068-2-75

Application

The Pendulum Impact Test Apparatus is manufactured in accordance with the requirements of IEC60068-2-75, IEC60884-1 clause 24.1, etc. It is suitable for the mechanical strength test of electrical accessories such as plugs and sockets for household and similar purposes, and surface-mounted installation boxes, screw glands, covers, switches, etc.

The test device mainly consists of a pendulum whose upper end can be kept swinging in a vertical plane around its pendulum axis. The axis of the pendulum shaft is 1000 mm above the measuring point. The pendulum consists of a rigid pendulum shaft and an impact element that meets the requirements. For heavier, bulkier or difficult-to-handle test samples, a portable pendulum can be used for testing. This device is a low-energy pendulum impact device below 2J. It should be fixed vertically on a solid wall. The mounting bracket seat can be adjusted forward and backward, left and right, and the impact angle can be adjusted.

Test Principle:

Test Eha: Pendulum Hammer, the striking element is free released at a certain height through a 1 m pendulum tube, impact the specimen at the lowest point in the vertical direction, after the conversion of gravitational potential energy to kinetic energy, to achieve the purpose of impact test on the sample.

Structure:

The low energy pendulum impact test device is mounted to the wall, the sample mounting bracket is adjustable up, down, left and right, and the angle can be adjusted by pivot, thereby achieving impacts on different positions on the front side and impacts on side of the sample.
