This application provides an arc-blocking device and a circuit breaker, belonging to the field of electrical equipment technology. In this arc-blocking device, one end of an elastic element is connected to the circuit breaker housing, and the other end is connected to an arc-blocking element, which is located on the movement trajectory of the circuit breaker's moving contact. When the moving and stationary contacts of the circuit breaker are in contact, the arc-blocking element is located on the side of the moving contact facing away from the stationary contact. During the separation process of the moving and stationary contacts, the moving contact pushes against the first side of the arc-blocking element, causing the arc-blocking element to drive the elastic element to bend and deform in the first direction until the moving contact slips off from the first side. Then, under the elastic force of the elastic element, the arc-blocking element moves in the second direction to between the moving and stationary contacts, thereby forcibly cutting off the arc generated when the moving and stationary contacts separate. It has good breaking capacity and can effectively improve the arc-extinguishing capability of the circuit breaker. Furthermore, the arc-blocking device provided in this embodiment has a simple structure, is easy to assemble, operates reliably, and has a certain degree of universality.

This application relates to the technical field of self-piercing riveting, and more specifically, to a self-piercing riveting device, a control method for the self-piercing riveting device, and related equipment. The self-piercing riveting device includes a first stamping part, a second stamping part, and a pressure sensor. The first stamping part pushes the tail of the rivet to apply pressure to the rivet, causing it to penetrate the multi-layered sheet metal. The pressure sensor detects the pressure applied to the rivet by the first stamping part. When a sudden change in pressure is detected, it indicates that the rivet has penetrated all the sheet metal. The second stamping part applies pressure to the tip of the rivet, causing it to deform and form a flange that abuts against the sheet metal. This ensures that the rivet completely penetrates all the sheet metal while preventing it from coming out, reducing the risk of loosening of the sheet metal during subsequent use. Furthermore, the riveting status can be detected without destructive testing, reducing testing costs and improving the efficiency of self-piercing riveting.
