Description

Technical Field

[0001] This utility model relates to the field of arc-leading angle fixing technology, and in particular to a static contact arc-leading angle riveting clamp. Background Technology

[0002] Stationary contacts refer to contacts whose position remains basically unchanged during operation. They are widely used as the main conductive contact material in relays, contactors, load switches, medium and low voltage circuit breakers, as well as household appliances and automotive electrical appliances (horn, headlights, ignition) and other switching electrical appliances.

[0003] In existing technologies, an arc-starting angle is typically riveted to one end of the stationary contact, such as... Figure 1 As shown, the stationary contact includes a wiring part (1), a stationary contact plate (2), a bending part (3) and a stationary contact bearing part (4). A through groove is provided in the middle of the stationary contact plate (2), and the arc angle (5) is riveted to the stationary contact bearing part (4).

[0004] When riveting the arc-starting angle, most companies still manually hold the stationary contact with one hand and the rivet with the other, and then perform stamping and riveting under the stamping equipment. This can easily lead to uneven manual clamping force, resulting in problems such as rivet misalignment and tilting of the arc-starting angle. Utility Model Content
