Description

Technical Field

[0001] This utility model relates to the field of terminal production technology, specifically to a terminal housing riveting and straightening fixture. Background Technology

[0002] A terminal is an accessory product used to achieve electrical connections. It is widely used in electronic equipment, electrical circuits and other scenarios. It is usually connected to other electrical components through wires to transmit current or signals. During the production process, terminals are usually connected to the circuit by riveting.

[0003] Currently, because the force applied during the riveting of the terminal housing is only applied to the connection between the circuit and the terminal housing, one end of the terminal housing is always suspended or unpositioned. During the riveting process, deformation is very likely to occur, resulting in a low pass rate for the terminals during riveting. Utility Model Content
