Power plug pulling force testing device

Abstract

The invention discloses a power plug pulling force testing device, which comprises a base, a first support, a second support, a rotating assembly, a lever, and a hanging piece, wherein the base comprises a bearing surface; one end of the second support and one end of the first support are arranged on the bearing surface; the rotating assembly comprises a turntable and a handle; the turntable is connected onto the other end of the first support in a rotating mode and is eccentrically arranged onto the other end of the first support; the handle is arranged on the turntable; one end of the lever is connected onto the other end of the second support in a rotating mode; the other end of the lever abuts against the peripheral surface of the turntable; the lever comprises a fixing part; and the hanging piece is used for being connected onto a tested power plug. According to the power plug pulling force testing device, the lever rises or falls in the vertical direction via the rotating assembly, the hanging piece connected with the tested power plug also rises and falls, different pulling forces are applied to the power plug for testing, and reliability and environmental adaptability of the tested power plug can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a pull-out force testing device for a power plug. Background technique [0002] The power plug is also called the power cord plug, and the power plug includes a power cord and a plug. The power plug can be roughly divided into conversion power plug, injection molding power plug and assembly power plug. Among them, the assembly power plug is that the power cord and the plug are fixed together by screws. This connection method is convenient for disassembly and assembly, ensuring the flexibility of assembling the power plug. . In actual assembly, there may be abnormal phenomena such as untightened screws, and in actual use, the assembly power plug is often pulled. If the screws are not tightened, the power cord may fall off from the plug and cause a short circuit, which may cause fire or personal injury. Therefore, the reliability and environmental adaptability of t...

Problems solved by technology

In actual assembly, there may be abnormal phenomena such as untightened screws, and in actual use, the assembly power plug is often pulled. If the screws are not tightened, the power cord may fall off from the plug and cause a short circuit, which may cause fire or personal injury. Injury, so the reliability and environmental adaptability of the assembly power plug must be considered when it is pulled out

In the prior art, there is no special device for testing the reliability of the plug when it is subjected to a pulling force, and the environmental adaptability and reliability of the plug in actual use cannot be guaranteed.
