Abstract

The present invention discloses a detection device for manufacturing silver-copper alloy contacts, which relates to the field of switch manufacturing technology and includes a support seat, wherein a guide slide is fixedly connected to the upper position of the inner side surface of the support seat, and a fixed plate is fixedly connected to the output end of the guide slide. The detection device for manufacturing silver-copper alloy contacts achieves that a positioning component pushes the middle position of the surface of multiple silver-copper alloy contacts through a gap, thereby pressing the silver-copper alloy contacts onto the inner side surfaces of the positioning component and the limiting component. At this time, the two contact ends of the silver-copper alloy contacts face the bottom of the positioning component and the top of the limiting component respectively. After the silver-copper alloy contacts are limited, the guide slide drives the fixed plate to move, so that the multi-position clamping component moves as a whole to the inside of the protective mechanism. The protective mechanism detects the resistances at both ends of multiple copper alloy contacts in sequence, solving the problems of small products and irregular appearance, inconvenient manual handling, and slow measurement efficiency.

Description

Technical Field

[0002] High-voltage switch contacts refer to the contacts in high-voltage switches, which are used to connect or disconnect in high-voltage circuits. High-voltage switches are usually used to control current in high-voltage power systems. Contacts are part of high-voltage switches and are responsible for conducting current when connected or disconnected. These contacts are usually made of wear-resistant and conductive materials to ensure reliable operation under high-voltage and high-current environments. Before using high-voltage switch contacts, it is necessary to detect the connected state, disconnected state, and resistance change between the contacts to ensure that the switch contacts can be used safely during use.
