Abstract
Claims
1. An anti-arcing contact assembly, characterized by: The system includes a stationary contact plate (1), a stationary contact point (2), and a guide sleeve (3). The stationary contact plate (1) includes a stationary contact plate mounting part (5), which extends horizontally at both ends to form a stationary contact plate contact part (6). The stationary contact plate contact part (6) is provided with a stationary contact plate positioning groove (7). The center of the stationary contact plate positioning groove (7) is provided with a stationary contact plate inner boss (8) at the same height as the upper surface of the stationary contact plate contact part (6). The stationary contact plate inner boss (8) is provided with a stationary contact plate riveting hole (9). The stationary contact point (2) includes a stationary contact point mating part (10) that contacts the moving contact point and a stationary contact point rivet (11) located at the bottom of the stationary contact point mating part (10). The stationary contact rivet (11) is riveted into the stationary contact plate rivet hole (9). The outer diameter of the inner boss (8) of the stationary contact plate is larger than the outer diameter of the stationary contact mating part (10). The arc guide sleeve (3) includes an arc guide sleeve body (13) placed in the positioning groove (7) of the stationary contact plate. The arc guide sleeve body (13) is provided with an arc guide sleeve clearance hole (14) corresponding to the inner boss (8) of the stationary contact plate. The upper end of the arc guide sleeve body (13) is provided with an L-shaped arc guide block (15). The upper surface of the L-shaped arc guide block (15) is higher than the upper surface of the stationary contact mating part (10). The inner diameter of the L-shaped arc guide block (15) is equal to the outer diameter of the stationary contact mating part (10).
2. The anti-arcing contact assembly of claim 1, wherein: The outer wall of the arc guide sleeve body (13) is provided with an arc guide sleeve external thread (16), and the inner wall of the static contact plate positioning groove (7) is provided with an arc guide sleeve internal thread (17) that is threadedly connected to the arc guide sleeve external thread (16).
3. The anti-arcing contact assembly of claim 1, wherein: The L-shaped arc guide block (15) has a wedge-shaped arc guide head (18) at its front end.
4. The anti-arcing contact assembly of claim 1, wherein: The upper end of the arc guide sleeve (13) is provided with L-shaped arc guide blocks (15) spaced around an arc, and there are two L-shaped arc guide blocks (15).
5. The anti-arcing contact assembly of claim 1, wherein: The bottom of the contact part (6) of the stationary contact plate is provided with a stationary contact plate annular boss (20) at the stationary contact plate positioning groove (7).
6. The anti-arcing contact assembly of claim 1, wherein: Both the static contact plate (1) and the arc guide sleeve (3) are made of pure copper.
7. The anti-arcing contact assembly of claim 1, wherein: The static touch plate mounting part (5) has a static touch plate limiting hole (21) at the center, and the static touch plate mounting part (5) has static touch plate positioning recesses (22) at the front and rear ends to facilitate anti-movement during installation.
