Description

Technical Field

[0001] This utility model relates to the technical field of plug testing devices, and more specifically, to a testing device for distinguishing US standard plugs. Background Technology

[0002] A power plug is a device that connects electrical appliances and other devices to a power source. Power sockets and plugs vary in shape, rating, size, and type depending on the country or region. For example, the structure of a US standard plug consists of two parallel, spaced-apart conductive terminals, which are flat and plate-shaped; the structure of a European standard plug also consists of two conductive terminals in a straight line, which are round and rod-shaped; while the structure of a British standard plug has three conductive terminals arranged in a triangle, which are thicker and plate-shaped.

[0003] Some plug manufacturers produce US standard plugs after receiving orders from American customers. However, European or British standard plugs may inevitably be mixed in with the same batch. This not only renders the plugs unusable after delivery but also damages trust with the customer. To address this, plug manufacturers typically manually remove non-compliant European or British standard plugs from the batch during the necessary quality inspection process (checking if the plugs can conduct electricity) after producing US standard plugs. However, because European and US standard plugs have similar structures, visual inspection alone may introduce errors and cannot guarantee that other standard plugs are not mixed in with the same batch of US standard plugs. Therefore, a testing device for distinguishing US standard plugs is needed. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a testing device for distinguishing US standard plugs.
